Characterization of acidic components in Midway Sunset crude oil  

SciTech Connect

The crude oil from the Midway Sunset Field in California contains 70% non-distillable constituents called resid. Analysis of Midway Sunset crude components using standard analytical techniques such as GC and GC-MS is difficult due to the complex and intractable nature of the resid. Acidic components in crudes are of importance because the presence of these compounds results in problems related to pipe corrosion and waste-water contamination. Detailed characterization of the acidic components of Midway Sunset crude using high-resolution electron impact (HREI) and chemical ionization (HRCI) mass spectrometry have been undertaken.

Reactivation of an Idle Lease to Increase Heavy Oil Recovery Through Application of Conventional Steam Drive Technology in a Low Dip Slope and Basin Reservoir in the Midway-Sunset Field, San Jaoquin Basin, California  

SciTech Connect

A previously idle portion of the Midway-Sunset field, the ARCO Western Energy Pru Fee property, is being brought back into commercial production through tight integration of geologic characterization, geostatistical modeling, reservoir simulation, and petroleum engineering. This property, shut-in over a decade ago as economically marginal using conventional cyclic steaming methods, has a 200-300 foot thick oil column in the Monarch Sand. However, the sand lacks effective steam barriers and has a thick water-saturation zone above the oil-water contact. These factors require an innovative approach to steam flood production design that will balance optimal total oil production against economically viable steam-oil ratios and production rates. The methods used in the Class III demonstration are accessible to most operators in the Midway-Sunset field and could be used to revitalize properties with declining production of heavy oils throughout the region.

Reservoir simulation improves implementation of Midway Sunset steamflood  

SciTech Connect

Thermal reservoir simulation was utilized to understand, make development recommendations, and project the performance of the Monarch C steamflood in a portion of Mobil`s South Midway Sunset field. The Monarch, a thick sequence of complex turbidite deposition, is characterized by extreme geological heterogeneity (lithofacies-controlled permeability and saturation variation, and mudstone barrier layers). Steamflood performance in the Monarch is related directly to the reservoir quality, and the path of steam flow is significantly influenced by the numerous laterally extensive mudstone barriers. The fine grain clay-bearing sediments were deposited on the anticline, distal from the source, whereas the coarser grain sediments, with little clay, were deposited on the more proximal syncline and steep dip areas. Consequently, steamflood performance improves relative to the crest since reservoir quality improves (including oil saturation), clay content decreases, and structure (dip) becomes more pronounced.

Midway-Sunset keeps producing oil with a little help from steam injection  

SciTech Connect

The largest field in the lower 48 states runs on steam injection and well-honed maintenance. The glory days of the Midway-Sunset field had been gone for more than four decades by the beginning of the 1960s. Production had peaked in 1914 with an average of 94,140 bo/d. The field, except for an occasional spike, had been in decline until steam-injection began. The advent of steam injection to increase recovery of the field`s heavy crude began on a pilot basis in 1963. If anyone had predicted the dramatic effect steam would have on Midway-Sunset as well as other California heavy crude fields, the prediction would have been met with total disbelief. The first steam project in California had been initiated by Shell Oil Co. in the Yorba Linda field in the Los Angeles Basin in 1960. Other pilot projects followed in the Coalinga and Kern River fields. Today, Berry Petroleum Co. continues as one of the field`s most successful steamers. The company`s ongoing steam efforts have played a major role in making Berry the top California-based independent producer in the field. Steam contributed to the posting by Berry of a 32% increase in this year`s second quarter earnings.

Steam management in composite mature steam floods, Midway Sunset field  

SciTech Connect

Vogel noted that oil production rates in many steam floods are not predictable from steam injection rates and must be estimated on some other basis. He presented a conservative method, based on simple models assuming instantaneous steam overlay, to calculate heat requirements once the oil rate is known. By more accurately describing the reservoir being flooded and the steam flood process, Vogel`s method was refined resulting in significant steam savings for SWEPI`s leasehold in the northern part of the Midway Sunset field. Analytical expressions are presented for (1) the heat required to support a steam chest descending into an oil column, (2) the heating of a cap or base rock already partially heated by an adjacent steam flood and (3) the heating of a cap or base rock which is exposed to a uniformly growing steam zone. A method is also described to operate a mature steam flood at a constant oil steam ratio while scavenging some heat stored in the steam zone.

Surface geology of the northern Midway-Sunset Field and adjacent Temblor Range, Kern County, California  

SciTech Connect

New surface mapping at a 1:12000 scale adjacent to the 2 billion barrel Midway Sunset Field has revealed complex intraformational stratigraphy within the upper Miocene Santa Margarita Formation (Tms). Locally known as the Potter and Spellacy Formations in the subsurface, these sandstone and conglomerate heavy oil reservoirs produce the majority of Midway Sunset daily production of 164,000 barrels of oil via thermal EOR processes. The Tms consists mostly of conglomerate inserted into the Belridge Diatomite (Tmb) interval. The stratigraphically lower intervals of the Tms clearly fill deeply incised valleys or submarine canyons cut into Tmb and locally into the underlying Antelope Shale (Tma). The basal intervals of Tms; are very coarse grained, containing boulders of granitic and metamorphic rock as large as 4 meters that were derived from the Salinian block west of the San Andreas Fault. The upper intervals of Tms are more sheet-like and interbedded containing clasts less than 50 cm in length. The incised valleys have a spacing of about one mile in outcrop, with a gap located in the area of the older Republic Sandstone (Tmr). Paleocurrents from Tms regionally suggest sediment transport to the northeast. The sedimentary structures of Tms suggest deposition in deep-water conditions, probably a slope (bathyal) setting. Shelf environments should have been present to the southwest (now stripped away by erosion) and submarine-fan and basin-floor environments to the northeast.

Comparison of cracking kinetics for Kern River 650{degrees}F residuum and midway sunset crude oil  

SciTech Connect

Kern River 650{degrees}F{sup +} residuum and Midway Sunset crude oil were examined by micropyrolysis at several constant-heating rates to determine pyrolysis cracking kinetics. Determined by the discrete distribution method, both feeds exhibited principal activation energies of 50 kcal/mol and frequency factors {approximately}10{sup 13} sec{sup -1}. Energy distributions were similar ranging from 45 to 57 kcal/mol. Determined by the shift-in-T{sub max} method, the E{sub approx} and A{sub {approx}} for Kern River 650{degrees}F{sup +} and Midway Sunset were 48 kcal/mol, 1.3 X 10{sup 12} sec{sup -1}, and 46 kcal/mol and 4.6 X 10{sup 11} sec{sup -1}, respectively. These results are similar, but not identical to other kinetic parameters for heavy oils from type II source rocks.

Integrated, multidisciplinary reservoir characterization, modeling and engineering leading to enhanced oil recovery from the Midway-Sunset field, California  

SciTech Connect

The Pru Fee property is developed in a heavy oil, Class III (slope and basin clastic sand), reservoir of the Midway-Sunset field, San Joaquin Basin, California. Wells on the property were shut-in with an estimated 85% of the original oil remaining in place because the reservoir failed to respond to conventional cyclic steaming. Producibility problems are attributed to the close proximity of the property to the margin of the field. Specific problems include complex reservoir geometry, thinning pay, bottom water, and dipping beds. These problems are likely common at the margins of the Midway-Sunset and other Class III reservoirs. This project forms the first step in returning the property to production and explores strategies that might be applied elsewhere. Reservoir characterization, modeling, and engineering methods are integrated to design, simulate, and implement a pilot steam flood. A new drillhole provides good quality, core through the pay zone and a full suite of geophysical logs. Correlations between geological and petrophysical data are used to extrapolate reservoir conditions from older logs and yield a 3-dimensional petrophysical model. Numerical results illustrate how each producibility problem might influence production and provide a framework for designing the pilot steam flood. This first phase illustrates how a multidisciplinary team can use established technologies in developing the detailed petrophysical, geological, and numerical models needed to enhance oil recovery from marginal areas of Class III reservoirs.

Steam-foam pilot project in Dome-Tumbador, Midway-Sunset field  

SciTech Connect

This paper describes a steam-foam pilot project in the Potter sand, Midway-Sunset field. The pilot consists of four inverted five-spot patterns with a confined producer covering 5.2 acres (2.1 ha). Steam foam was generated by continuous injection of steam with NaCl, alpha olefin sodium sulfonate, and nitrogen. Production and subsurface data, obtained from two observation wells, were used as monitoring tools in the pilot. Overall, during the first 2 years of foam injection, 207,000 bbl (32 900 m/sup 3/) of incremental oil was produced.

One of the main objectives of Budget Period I was to return the Pru Fee property to economic production and establish a baseline productivity with cyclic steaming. By the end of the second quarter 1996, all Pru producers except well 101 had been cyclic steamed two times. Each steam cycle was around 10,000 barrels of steam (BS) per well. No mechanical problems were found in the existing old wellbores. Conclusion is after several years of being shut-in, the existing producers on the Pru lease are in reasonable mechanical condition, and can therefore be utilized as viable producers in whatever development plan we determine is optimum. Production response to cyclic steam is very encouraging in the new producer, however productivity in the old producers appears to be limited in comparison.

Stratigraphy of Upper Miocene Potter sands, Midway-Sunset field, Kern County, California  

SciTech Connect

Upper Miocene Potter sands in the northern part of the Midway-Sunset field were analyzed extensively using detailed electric-log correlations. Structural and stratigraphic cross sections and subsurface mapping demonstrate variations across four general areas in T31S, R22E, referred to as west (parts of Secs. 16, 17, 21), north (parts of Secs. 15, 16), east (part of sec. 14), and south (within Sec. 27). Potter sands deposited in the west area represent the oldest strata of the Potter sequence because they unconformably overlie older silts, diatomaceous shales, and isolated sand channels believed to be part of the Antelope Shale Member. These sands are interpreted to represent massive debris flow/grain flows deposited in a proximal channel-trough system that carried sediments from west to east, toward the low point of the Midway syncline. In the north area, Potter sands change abruptly from massive sands in the eastern part of Sec. 16 to thinner sand channels with more correlative and continuous silt interbeds in Sec. 15. The massive sands are stratigraphically equivalent, if not slightly younger than, sands in the west. However, at the base, these sands depositionally onlap onto the southwest flank of the globe anticline. The Potter sand channel packages thin in Sec. 15, which represents lateral facies changes within the system as the sand to silt ratios become lower and the silts become more continuous. Potter sands in the east area are the uppermost and youngest strata encountered in the study area. Although massive sand channel packages are common, they show better lateral continuity and exhibit lower sand to silt ratios than the north sequences. In the south area, Potter sands are interbedded with continuous silt units that can be mapped over much of the section.

Steam-foam mechanistic field trial in the Midway-Sunset field  

SciTech Connect

A one-pattern, steam-foam mechanistic field trial was conducted in Section 26C of the Midway-Sunset field (upper Monarch sand). The test objectives were (1) to understand the mechanisms of steam diversion caused by foam under reservoir conditions, (2) to establish whether foam can exist in-depth away from the injection well, and (3) to measure incremental oil that can be attributed to foam. Surfactant was injected with steam and nitrogen continuously, and bottom-hole injection pressure (BIHP) increased from 100 to 300 psig, indicating good foam generation. Better steam distribution across the injector's perforations occurred when foam was generated. Improvements in both vertical and areal sweep efficiency of steam were observed. Substantial temperature and gas saturation increases coincided with surfactant breakthrough and local reservoir pressure increases at observation wells. Complementary laboratory core-floods showed that foam generation could occur at low-pressure gradients, which are typical of in-depth conditions. Both laboratory and field data were interpreted as evidence that the in-depth presence of foam was the result of local generation wherever surfactant, steam, and nitrogen were present, rather than propagation of a foam bank generated near the injector. Some oil-production increase was also observed during the test; however, an accurate quantitative estimate of incremental oil owing to foam was difficult to establish.

Architecture and sedimentology of turbidite reservoirs from Miocene Moco T and Webster zones, Midway-Sunset field, California  

SciTech Connect

Thirty-five turbidite sandstone bodies from the Moco T and Webster reservoir zones were delineated for enhanced oil recovery projects in Mobil's MOCO FEE property, south Midway-Sunset field. The recognition of these sand bodies is based on mappable geometries determined from wireline log correlations, log character, core facies, reservoir characteristics, and comparison to nearby age-equivalent outcrops. These turbidite sands are composed of unconsolidated arkosic late Miocene sandstones (Stevens equivalent, Monterey Formation). They were deposited normal to paleoslope and trend southwest-northeast in an intraslope basin. Reservoir quality in the sandstone is very good, with average porosities of 33% and permeabilities of 1 darcy.

Multi-well subsurface study of the stratigraphic sequence of the Potter Formation in the Midway-Sunset Field, Kern County, California  

SciTech Connect

To understand the stratigraphic nature of the Potter Formation reservoirs, a multi-well study along a west-east cross-section was done using dipmeter, Formation MicroScanner, and FMI{trademark} (Fullbore Formation Microlmager) data. Thermal EOR wells are drilled only into the heavy oil-bearing portion of the reservoir, thus each well does not penetrate the complete Potter sequence, but penetrates successively younger sandstone and conglomerate members from west to east. Wireline logs and continuous core data were used for correlation and calibration of the dip and image data. The image data revealed detailed stratification, bedding, and sedimentary structures, identifying conglomeratic, bioturbated and stratified sequences. Correlation with continuous core clarified which features were more interpretive. The image data, available on three of the eleven wells, was then correlated to dipmeter data, both in the form of computed dip data and interpolated electrical images. Each of the eleven wells penetrated only one or two members of the Potter Formation. Using the dip data, it was possible to reconstruct a true stratigraphic thickness type log of the Potter Formation. The interpreted stratigraphic data, revealing bedded, bioturbated, and conglomeratic depositional systems was combined into a single type log of the Potter Formation. The resultant type log can be used for various sequence stratigraphic, engineering, and thermal EOR reservoir characterization applications in the Midway-Sunset Field.

Multi-well subsurface study of the stratigraphic sequence of the Potter Formation in the Midway-Sunset Field, Kern County, California  

SciTech Connect

To understand the stratigraphic nature of the Potter Formation reservoirs, a multi-well study along a west-east cross-section was done using dipmeter, Formation MicroScanner, and FMI[trademark] (Fullbore Formation Microlmager) data. Thermal EOR wells are drilled only into the heavy oil-bearing portion of the reservoir, thus each well does not penetrate the complete Potter sequence, but penetrates successively younger sandstone and conglomerate members from west to east. Wireline logs and continuous core data were used for correlation and calibration of the dip and image data. The image data revealed detailed stratification, bedding, and sedimentary structures, identifying conglomeratic, bioturbated and stratified sequences. Correlation with continuous core clarified which features were more interpretive. The image data, available on three of the eleven wells, was then correlated to dipmeter data, both in the form of computed dip data and interpolated electrical images. Each of the eleven wells penetrated only one or two members of the Potter Formation. Using the dip data, it was possible to reconstruct a true stratigraphic thickness type log of the Potter Formation.

Reactivation of an idle lease to increase heavy oil recovery through application of conventional steam drive technology in a low dip slope and basin reservoir in the Midway-Sunset field, San Joaquin basin, California. Quarterly report, January 1--March 31, 1996  

SciTech Connect

This project will reactivate ARCO`s idle Pru Fee lease in the Midway-Sunset field, California and conduct a continuous steamflood enhanced oil recovery demonstration aided by an integration of modern reservoir characterization and simulation methods. The objectives of the project are: (1) to return the shut-in portion of the reservoir to commercial production; (2) to accurately describe the reservoir and recovery process; and (3) convey the details of this activity to the domestic petroleum industry, especially to other producers in California, through an aggressive technology transfer program. The producibility problems initially thought to be responsible for the low recovery in the Pru Fee property are: (a) the shallow dip of the bedding; (b) complex reservoir structure, (c) thinning pay zone; and (d) the presence of bottom water. The project is using tight integration of reservoir characterization and simulation modeling to evaluate the magnitude of and alternative solutions to these problems. Two main activities were brought to completion during the first quarter of 1996: (1) lithologic and petrophysical description of the core taken form the new well Pru 101 near the center of the demonstration site and (2) development of a stratigraphic model for the Pru Fee project area. In addition, the first phase of baseline cyclic steaming of the Pru Fee demonstration site was continued with production tests and formation temperature monitoring.

SciTech Connect

This project will reactivate ARCO`s idle Pru Fee lease in the Midway-Sunset field, California and conduct a continuous steamflood enhanced oil recovery demonstration aided by an integration of modern reservoir characterization and simulation methods. Cyclic steaming will be used to reestablish baseline production within the reservoir characterization phase of the project. During the demonstration phase, a continuous steamflood enhanced oil recover will be initiated to test the incremental value of this method as an alternative to cyclic steaming. Other economically marginal Class 3 reservoirs having similar producibility problems will benefit from insight gained in this project. The objectives of the project are: (1) to return the shut-in portion of the reservoir to commercial production; (2) to accurately describe the reservoir and recovery process; and (3) to convey the details of this activity to the domestic petroleum industry, especially to other producers in California, through an aggressive technology transfer program. A summary of technical progress discusses the literature compilation, assembly of digitized log suites, development of a stratigraphic framework, installation of lease production facilities, return wells to production, drill producer and observation wells, and reservoir characterization.

Oil-field disposal practices in hydrogeologic setting of Midway Sunset and Buena Vista oil fields; review of past effects, current activities, and future scenarios  

SciTech Connect

Class 2 water disposal in the Midway Sunset and Buena Vista oil fields of Kern County, California, has been by injection and infiltration from spreading ponds into the unsaturated zone, which is typically hundreds of feet thick. Water collection is mostly through an extensive tributary network of collection ditches radiating from several disposal facility locations. The purpose of this study was to evaluate the subsurface movement of fluid in the hydrogeological environment and to determine the fate of the disposed water and its long-term impact on the area.

Reservoir description of a sand-rich submarine fan complex for a steamflood project: upper Miocene Potter sandstone, North Midway Sunset field, California  

SciTech Connect

Nearly 650 m of cores from the upper Miocene Potter sandstone in Mobil's Alberta/Shale property, North Midway Sunset field, California, were examined to determine depositional facies, sand-body geometry, and reservoir quality for a proposed steamflood project. The Potter represents a sand-rich submarine fan complex with braided-channel, meandering-channel, levee, and crevasse-splay facies. The braided-channel facies (gravel and coarse sand) is thick (up to 100 m), sheetlike (> 500 m wide), and highly permeable (10,000 + md). The meandering-channel facies (coarse to medium sand) is up to 20 m thick, over 400 m long, lenticular in geometry, and exhibits an upward decrease in permeability (e.g., 9000 to 500 md) related to grain size that fines upward. The levee facies (in bioturbated sand) is up to 21 m thick, shows variable geometry, and is generally low in permeability (100-1500 md). The crevasse splay (medium sand) is up to 12 m thick, sheetlike (> 300 m wide), and shows moderately high permeability (2000-8000 md). The braided-channel facies was a product of density-modified grain flows, and the remaining three facies were deposited by turbidity currents. Steam flooding of the Potter reservoir should perform extremely well because the entire reservoir is composed of relatively clean sand and the reservoir lacks both horizontal and vertical permeability barriers.

[open quotes]2-Step[close quotes] log analysis of the Spellacy reservoir in the giant Midway-Sunset Field, Kern County, California  

SciTech Connect

A technique is presented for simple, effective log analysis of (Miocene) [open quotes]Spellacy[close quotes] sands and conglomerates of the Santa Margarita Formation at Midway-Sunset Field in Kern County, California. Results are shown graphically on the log display and are quantified for mapping. Requirements are digital wireline data -- in this simple case, just resistivity and porosities - and flexible log analysis software such as QLA2[trademark]. The first step of this technique discriminates between reservoir-quality and non-reservoir-quality intervals yielding three color-coded categories. A narrow color-filled column is added to the well log display to graphically communicate the vertical distribution of reservoir-quality and barrier intervals. The second step performs a fluid analysis on the reservoir-quality category (intervals) yielding three more color-coded categories. The results of the fluid analysis are graphically displayed in a second narrow color-filled column on the well log. Analysis results are captured from a tabular report for mapping. Quantifiable products include (1) thicknesses: original net pay, current net pay, reservoir quality, total sand, total porosity, phi-H, etc.; (2) averages: original net pay porosity; current net pay porosity, current net pay saturation, current net pay bulk volume oil, etc.; and (3) ratios: thickness of reservoir quality to total sand and thickness of current net pay to total interval.

Reactivation of an Idle Lease to Increase Heavy Oil Recovery through Application of Conventional Steam Drive Technology in a Low Dip Slope and Basin Reservoir in the Midway-Sunset Field, San Jaoquin Basin, California, Class III  

SciTech Connect

During the initial phase of the project a multifaceted feasibility study was carried out to examine whether the pilot project could be justified technically and economically at this site. This study included: (1) Recompletion of 9 shut-in wells and drilling of a additional producer and a new temperature observation well. A core was taken from the reservoir interval in the new producer, Pru-101. The wells were produced by conventional cyclic steaming over a period of 15 months to establish a production baseline for the site, (2) Characterization of the stratigraphy and petrophysical properties of the Monarch Sand reservoir using existing well logs and analyses on samples in the core taken from Pru-101. The resulting data were used to develop a geostatistical model of the reservoir at the Pru Fee property and a specific reservoir simulator for the pilot test site on the property, and (3) Use of the reservoir simulator to test various steamflood and cyclic steaming production options leading to design of a production strategy for the pilot steamflood based on a four pattern, 9-spot array covering 8 ac near the center of the 40 ac Pru Fee property. The array chosen required drilling additional producers and injectors to supplement the existing wells recompleted in the initial phase of the project.

Gravity and magnetic data of Midway Valley, southwest Nevada  

SciTech Connect

Detailed gravity and ground magnetic data collected along five traverses across Midway Valley on the eastern flank of Yucca Mountain in southwest Nevada are described. These data were collected as part of an effort to evaluate faulting in the vicinity of proposed surface facilities for a potential nuclear waste repository at Yucca Mountain. Geophysical data show that Midway Valley is bounded by large gravity and magnetic anomalies associated with the Bow Ridge and Paintbrush Canyon faults, on the west side of Exile Hill and on the west flank of Fran Ridge, respectively. In addition, Midway Valley itself is characterized by a number of small-amplitude anomalies that probably reflect small-scale faulting beneath Midway Valley.

In the theory of Sumi and Kakitani on electron transfer (ET) via a midway molecule, the overall ET was formulated using the second-order perturbation method and phenomenologically incorporating the renormalization factor in the intermediate state to escape from the divergence of the rate. In this Letter, we developed a nonperturbative theory of the ET via a midway molecule and we have succeeded in naturally deriving the above renormalization factor under certain approximations.

Revised age for Midway volcano, Hawaiian volcanic chain  

Science Journals Connector (OSTI)

New conventional K-Ar,40Ar/39Ar, and petrochemical data on alkalic basalt pebbles from the basalt conglomerate overlying tholeiitic flows in the Midway drill hole show that Midway evolved past the tholeiitic shield-building stage and erupted lavas of the alkalic suite27.0 ± 0.6m.y. ago. The data also show that previously published conventional K-Ar ages on altered samples of tholeiite are too young by about 9 m.y. These results remove a significant anomaly in the age-distance relationships of the Hawaiian chain and obviate the need for large changes in either the rate of rotation of the Pacific plate about the Hawaiian pole or the motion of the plate relative to the Hawaiian hot spot since the time of formation of the Hawaiian-Emperor bend. All of the age data along the Hawaiian chain are now reasonably consistent with an average rate of volcanic propagation of 8.0 cm/yr and with 0.83°/m.y. of angular rotation about the Hawaiian pole.

Accumulation and toxicity assessment of polychlorinated biphenyls in black-footed albatross (Diomedea nigripes) from Midway Atoll, North Pacific Ocean  

Science Journals Connector (OSTI)

Polychlorinated biphenyls (PCBs) are ubiquitous chemicals that were used as additives in capacitors and transformers; and heavy contamination in the past of Midway Atoll, a national wildlife refuge, puts the wildlife, including the black-footed albatross (BFAL), at risk. In this study, we assess the profiles and toxicity of the individual PCB congeners at a natural equilibrium state in various tissues of 1-month old and 4–5-month old BFAL chicks and black-footed and Laysan albatross eggs found on the atoll. In the 1-month old chicks from Midway Atoll, the major seven congeners \\{PCBs\\} 99, 118, 138, 153, 170, 180 and 183 accounted for 36–78% of the total \\{PCBs\\} in the various body parts, and the total PCB concentrations in the bird samples are inversely related to the total body weights. In the 4–5-month old chicks, these same congeners accounted for much lower percentages (7–26%) than in the 1-month-old chicks, with higher amounts of the less chlorinated congeners. The total toxic equivalents (TEQs) for all of the tissues in the 1-month old chicks ranged from 130 to 11,000 pg g?1 (lipid weight, lw), and the total \\{TEQs\\} for the 4–5-month old chicks ranged from 18,000 to 100,000 pg g?1. The average total concentration was 7.9 and 4.6 ?g g?1 lw in the BFAL eggs and Laysan albatross eggs, respectively. The high concentrations could be accounted for by the age and PCB accumulation of the female producing the egg. The average \\{TEQs\\} were 70 and 90 pg g?1 in the Laysan albatross eggs and BFAL eggs, respectively. This PCB concentration and toxicity information can be used to determine the toxicological risk of the BFAL chicks while nesting at Midway Atoll, and the analysis of the albatross eggs is an indication of the contamination of the female albatross at the time of egg formation, with the levels acting as an indicator of the total PCB body burdens that the females are experiencing. The information from this study is indicative of the toxicological risk to the seabirds that nest and feed near Midway and of the overall PCB contamination in the North Pacific Ocean.

No Sunset and Extended Policies cases No Sunset and Extended Policies cases Annual Energy Outlook 2010 with Projections to 2035 No Sunset and Extended Policies cases Background The AEO2010 Reference case is best described as a “current laws and regulations” case, because it generally assumes that existing laws and fully promulgated regulations will remain unchanged throughout the projection period, unless the legislation establishing them specifically calls for them to end or change. The Reference case often serves as a starting point for the analysis of proposed legislative or regulatory changes, a task that would be difficult if the Reference case included “projected” legislative or regulatory changes. As might be expected, it is sometimes difficult to draw a line between what should be included or excluded from the Reference case. Areas of particular uncertainty include:

Metals in albatross feathers from Midway Atoll: Influence of species, age, and nest location  

SciTech Connect

In this paper the authors examine the concentrations of metals (heavy metals, mercury, lead, cadmium, chromium, manganese, tin; and metalloids, arsenic and selenium), in the down and contour (body) feathers of half-grown young albatrosses, and contour feathers of one of their parents. They collected feathers from Laysan Diomedea immutabilis and black-footed Diomedea nigripes albatrosses from Midway Atoll in the central Pacific Ocean. The authors test the null hypotheses that there is no difference in metal levels as a function of species, age, feather type, and location on the island. Using linear regression they found significant models accounting for the variation in the concentrations of mercury, lead, cadmium, selenium, chromium, and manganese (but not arsenic or tin) as a function of feather type (all metals), collection location (all metals but lead), species (selenium only), and interactions between these factors. Most metals (except mercury, arsenic, and tin) were significantly higher in down than in the contour feathers of either chicks or adults. Comparing the two species, black-footed albatross chicks had higher levels of most elements (except arsenic) in their feathers and/or down. Black-footed adults had significantly higher levels of mercury and selenium. They also collected down and feathers from Laysan albatross chicks whose nests were close to buildings, including buildings with flaking lead paint and those that had been lead-abated.

A midway forward-adjoint coupling method for neutron and photon Monte Carlo transport  

SciTech Connect

The midway Monte Carlo method for calculating detector responses combines a forward and an adjoint Monte Carlo calculation. In both calculations, particle scores are registered at a surface to be chosen by the user somewhere between the source and detector domains. The theory of the midway response determination is developed within the framework of transport theory for external sources and for criticality theory. The theory is also developed for photons, which are generated at inelastic scattering or capture of neutrons. In either the forward or the adjoint calculation a so-called black absorber technique can be applied; i.e., particles need not be followed after passing the midway surface. The midway Monte Carlo method is implemented in the general-purpose MCNP Monte Carlo code. The midway Monte Carlo method is demonstrated to be very efficient in problems with deep penetration, small source and detector domains, and complicated streaming paths. All the problems considered pose difficult variance reduction challenges. Calculations were performed using existing variance reduction methods of normal MCNP runs and using the midway method. The performed comparative analyses show that the midway method appears to be much more efficient than the standard techniques in an overwhelming majority of cases and can be recommended for use in many difficult variance reduction problems of neutral particle transport.

A new effective Monte Carlo Midway coupling method in MCNP applied to a well logging problem  

Science Journals Connector (OSTI)

The background of the Midway forward–adjoint coupling method including the black absorber technique for efficient Monte Carlo determination of radiation detector responses is described. The method is implemented in the general purpose MCNP Monte Carlo code. The utilization of the method is fairly straightforward and does not require any substantial extra expertise. The method was applied to a standard neutron well logging porosity tool problem. The results exhibit reliability and high efficiency of the Midway method. For the studied problem the efficiency gain is considerably higher than for a normal forward calculation, which is already strongly optimized by weight-windows. No additional effort is required to adjust the Midway model if the position of the detector or the porosity of the formation is changed. Additionally, the Midway method can be used with other variance reduction techniques if extra gain in efficiency is desired.

Baseline for beached marine debris on Sand Island, Midway Atoll  

Science Journals Connector (OSTI)

Baseline measurements were made of the amount and weight of beached marine debris on Sand Island, Midway Atoll, June 2008–July 2010. On 23 surveys, 32,696 total debris objects (identifiable items and pieces) were collected; total weight was 740.4 kg. Seventy-two percent of the total was pieces; 91% of the pieces were made of plastic materials. Pieces were composed primarily of polyethylene and polypropylene. Identifiable items were 28% of the total; 88% of the identifiable items were in the fishing/aquaculture/shipping-related and beverage/household products-related categories. Identifiable items were lowest during April–August, while pieces were at their lowest during June–August. Sites facing the North Pacific Gyre received the most debris and proportionately more pieces. More debris tended to be found on Sand Island when the Subtropical Convergence Zone was closer to the Atoll. This information can be used for potential mitigation and to understand the impacts of large-scale events such as the 2011 Japanese tsunami.

Metals in Albatross Feathers from Midway Atoll: Influence of Species, Age, and Nest Location  

Science Journals Connector (OSTI)

Female birds sequester some heavy metals in their eggs, which are then transferred to the developing embryo. Semiprecocial birds such as albatrosses are fully covered with down at hatching, but are dependent on their parents for food for many weeks. At hatching, levels of metals in the chick's down represent exposure from the female via egg, while levels in fully formed feathers at fledgling, several months later, represent mainly exposure from food provided by their parents. In this paper we examine the concentrations of “metals” (heavy metals, mercury, lead, cadmium, chromium, manganese, tin; and metalloids, arsenic and selenium), in the down and contour (body) feathers of half-grown young albatrosses, and contour feathers of one of their parents. We collected feathers from Laysan Diomedea immutabilis and black-footed Diomedea nigripes albatrosses from Midway Atoll in the central Pacific Ocean. We test the null hypotheses that there is no difference in metal levels as a function of species, age, feather type, and location on the island. Using linear regression we found significant models accounting for the variation in the concentrations of mercury, lead, cadmium, selenium, chromium, and manganese (but not arsenic or tin) as a function of feather type (all metals), collection location (all metals but lead), species (selenium only), and interactions between these factors. Most metals (except mercury, arsenic, and tin) were significantly higher in down than in the contour feathers of either chicks or adults. Comparing the two species, black-footed albatross chicks had higher levels of most elements (except arsenic) in their feathers and/or down. Black-footed adults had significantly higher levels of mercury and selenium. We also collected down and feathers from Laysan albatross chicks whose nests were close to buildings, including buildings with flaking lead paint and those that had been lead-abated. Lead levels in the down and feathers of chicks close to nonabated buildings were 10 times higher than for chicks from other locations. Conversely, levels of cadmium and tin were lower near the buildings. Near lead-abated buildings, lead levels decreased as a function of distance, indicating residual contamination on the soil. Our results indicate that black-footed albatross adults and chicks generally have higher levels of heavy metals in their feathers than Laysans. Chicks of both species have higher levels in their down than in their contour feathers, indicating potentially higher exposure during the early chick phase.

Ecological risk assessments for protected migratory birds and marine species at Midway Atoll  

SciTech Connect

In June 1997, the US Navy plans to close its Naval Air Facility on Sand Island and transfer the atoll to the US Fish and Wildlife Service for use as a National Wildlife Refuge. Midway provides breeding and feeding habitat for migratory seabirds, terrestrial and marine mammals, sea turtles and other reptiles, and a variety of reef fishes and invertebrates. As part of the base closure and transfer process, 36 sites of potential environmental concern were identified on Sand and Eastern islands. These sites include landfills and uncontrolled disposal areas, hazardous materials storage areas, abandoned transformers, sewer outfalls, and other potential hazardous waste sites. Potential contaminants include pesticides, PAHs, PCBs, and heavy metals. A screening ecological risk assessment was performed at each site with a goal of determining whether contaminants could pose any current or future risks to protected migratory bird or marine mammal wildlife species. Specific exposure pathways investigated were dermal and inhalation routes for ground-nesting and burrowing seabirds; incidental soil ingestion for shore birds; consumption for monk seals and sea turtles. Exposure analysis involved sediment and soil chemistry, marine invertebrate tissue chemistry, bioassays (bioavailability), and food web modeling. Effects analysis involved benthic infauna community analysis, acute and chronic invertebrate sediment bioassays, and extensive literature reviews. Risk characterization used both toxicity quotient methods and weight-of-evidence analysis. Because work by other investigators suggests that birds and perhaps marine wildlife acquire significant contaminant loads while feeding away from the atoll, on-atoll risk investigations had to consider whether atoll sites made significant marginal contributions to existing contaminant loads, particularly with respect to PCBs.

Paleomagnetism of Midway Atoll lavas and northward movement of the Pacific plate  

Science Journals Connector (OSTI)

Two deep drill holes through the reef limestones of Midway Atoll penetrated 120 m and 19 m of basaltic lavas that were dated by the \\{KAr\\} method at 18 my. Inclinations of natural remanent magnetization have been measured in 173 specimens cut from 57 core samples from 13 of the lava flows. The mean paleomagnetic inclination is27.6° ± 6.8°, corresponding to a paleolatitude of14.7° ± 4.2°. The present latitude of Midway is 28°, suggesting a northward component of motion of the Pacific plate of approximately 13° or 1400 km in the last 18 my. The paleolatitude of Midway is thus not significantly different from the present latitude (19°) of the active volcanic island of Hawaii. The paleomagnetic data from the Midway basalts thus support the hypothesis of Wilson and Morgan that volcanic heat sources are fixed with respect to the Earth's mantle below the asthenosphere and their apparent migration with time is due to plate motion.

Recent characterization activities of Midway Valley as a potential repository surface facility site  

SciTech Connect

Midway Valley, located at the eastern base of Yucca Mountain, Nye County, Nevada, has been identified as a possible location for the surface facilities of a potential high-level nuclear-waste repository. This structural and topographic valley is bounded by two north- trending, down-to-the-west normal faults: the Paintbrush Canyon fault on the east and the Bow Ridge fault on the west. Surface and near-surface geological data have been acquired from Midway Valley during the past three years with particular emphasis on evaluating the existence of Quaternary faults. A detailed (1:6000) surficial geological map has been prepared based on interpretation of new and existing aerial photographs, field mapping, soil pits, and trenches. No evidence was found that would indicate displacement of these surficial deposits along previously unrecognized faults. However, given the low rates of Quaternary faulting and the extensive areas that are covered by late Pleistocene to Holocene deposits south of Sever Wash, Quaternary faulting between known faults cannot be precluded based on surface evidence alone. Middle to late Pleistocene alluvial fan deposits (Unit Q3) exist at or near the surface throughout Midway Valley. Confidence is increased that the potential for surface fault rupture in Midway Valley can be assessed by excavations that expose the deposits and soils associated with Unit Q3 or older units (middle Pleistocene or earlier).

Preliminary gravity and magnetic models across Midway Valley and Yucca Wash, Yucca Mountain, Nevada  

SciTech Connect

Detailed gravity and ground magnetic data collected along ten traverses across Midway Valley and Yucca Wash on the eastern flank of Yucca Mountain in southwest Nevada are interpreted. These data were collected as part of an effort to evaluate faulting in the vicinity of proposed surface facilities for a potential nuclear waste repository at Yucca Mountain. Geophysical data show that Midway Valley is bounded by large gravity and magnetic anomalies associated with the Bow Ridge and Paintbrush Canyon faults, on the west side of Exile Hill and on the west flank of Fran Ridge, respectively. In addition, Midway Valley itself is characterized by a number of small-amplitude anomalies that probably reflect small-scale faulting beneath Midway Valley. Gravity and magnetic data across the northwest trending Yucca Wash and the inferred Yucca Wash fault indicate no major vertical offsets greater than 100 m using a density contrast of 0.2 to 0.3 g/cm{sup 3} along the proposed Yucca Wash fault. In addition, a broad magnetic high coincides with the approximate location of the hydrologic gradient and probably reflects moderately magnetic Topopah Spring Tuff or lavas in the Calico Hills Formation.

Upgrading of heavy oil from the San Joaquin valley of California by aqueous pyrolysis  

SciTech Connect

Midway Sunset crude oil and well-head oil were treated at elevated temperatures in a closed system with the presence of water. Mild to moderate upgrading, as measured by increasing in API gravity, was observed at 400 C or above. Reduced pressure operation exhibited upgrading activity comparable to upgrading under normal aqueous pyrolysis conditions. Reduced pressure operation was obtained by the use of specific blending methods, a surfactant, and the proper amount of water. The use of metal complexes provided additional upgrading. The best of the minimum set tested was Co(II) 2-ethylhexanoate. Fe, Zn, Mo, Cu, and Ni complexes also showed some levels of activity.

A mixed groundwater system at Midway, UT: discriminating superimposed local and regional discharge  

Science Journals Connector (OSTI)

Mixed thermal and cold water groundwater occurs in the Midway area, UT. Midway is located in the western Heber Valley, an alluvial-filled intermontane basin behind the crest of the Wasatch Mountains. In addition to streams and thermal springs, groundwater discharges from alluvium, bedrock, and karstified tufa. Evaluation of the thermal system reveals that it has been circulated to depths of ?2 km and temperatures of ?150 °C. Most groundwater characteristics of the area can be explained by subsurface mixing between isotopically depleted, Pleistocene-aged thermal water and isotopically enriched, cold, modern, low TDS groundwater. Because the entire system exhibits evidence of mixing, it is possible to define the regional extent of upwelling of thermal water, as well as mixing fractions between the two end-members. The subsurface mixing of thermal and non-thermal waters is highly controlled by the superimposition of local irrigation recharge.

Monitoring and reconstruction of a chairlift midway station in creeping permafrost terrain, Grächen, Swiss Alps  

Science Journals Connector (OSTI)

The midway station of a chairlift located in the ski resort Grächen (Swiss Alps) was originally built in 1997 at 2453 m ASL in alpine permafrost terrain. The chairlift conveys 300,000–330,000 passengers every winter season and constitutes an important link between two cable cars in the ski area. In winter 1997–1998, it became evident that the terrain at the mid-way station was unstable: one of the two concrete foundations started to creep and settle rapidly and cracks formed in the structure. To investigate the properties of the ground, two 25 m boreholes were drilled near the foundations and equipped with inclinometer casings and thermistors. The presence of permafrost with an exceptionally thick active layer and a 20-m talik containing water was confirmed. The horizontal and vertical deformation rates of the ground attained very high values between 2002 and 2003. As a consequence, and in the interest of the safety of the passengers, the original midway station had to be destroyed and a specially developed new station was built in 2003. The excavation trench was lined with insulating material in order to avoid thermal disturbance of the underlying permafrost by hydration heat. The new foundation consists of a concrete T-girder with three point bearings. Repositioning of the entire structure in response to creep is possible, due to the unique character of the structural bearings which can be raised or lowered using hydraulic cylinders and steel plates. The thermal regime of the entire structure, ground temperatures and slope movements continue to be monitored to determine the long-term evolution of the mid-way station.

Sedimentary regimes of upper Midway and lower Wilcox lignite in Alabama  

SciTech Connect

Paleoenvironments favorable for lignite deposition existed in sedimentary regimes of the Naheola Formation (upper Midway Group) and in Midway-Wilcox transition sediments apparently assignable to the Nanafalia Formation (Wilcox Group). In addition, lignite horizons are recognized in the Tuscahoma Sand (Wilcox Group). Lignite of potential economic significance occurs within the Naheola Formation west of Butler County and within the Nanafalia Formation east of Butler County. Lignite horizons in the Naheola Formation west of Butler County probably are not stratigraphically or time equivalent to lignite horizons east of Butler County. Depositional environments of the Naheola west of Butler County were favorable for development of lignite deposits with extensive lateral continuity, whereas lignite depositional environments east of Butler County apparently favored variability in thickness and lateral continuity. Estuarine and back-barrier coastal marsh environments are suggested for the lignite. Carbonaceous silt and clay in varying proportions are commonly associated with lignite in the Naheola Formation. Lithologic associations of lignite related to the Nanafalia Formation include quartzarenite, carbonaceous silt and clay, oyster beds, and limestone of the Clayton Formation (Midway Group).

Rescue of an extending capsulorrhexis by creating a midway tangential anterior capsular flap: a novel technique in 22 eyes  

Science Journals Connector (OSTI)

Objective: To show how an extending capsulorrhexis can be rescued by a midway tangential capsular flap in order to achieve an uneventful phacoemulsification. Design: Consecutive case series. Participants: Twenty-two eyes of 22 patients with extending capsulorrhexis treated at the Farabi Eye Hospital, Tehran. Methods: First, a tangential capsular opening was created on the border of the presumed continuous curvilinear capsulorrhexis just midway between the beginning of the capsulorrhexis and the edge of the extending capsulor-rhexis, to make a tangential flap of the anterior capsule. Second, the centre of this new flap was grasped and pulled centripetally until the edges of the new flap joined the edges of the extending flap to complete the capsulorrhexis. Results: The technique was successfully performed in all cases, leading to an uneventful phacoemulsification. Conclusions: Midway tangential capsular flap is a safe and effective technique to rescue an extending capsulorrhexis and leads to an uneventful phacoemulsification.

Persistent synthetic chlorinated hydrocarbons in albatross tissue samples from Midway Atoll  

SciTech Connect

Anthropogenic organic contaminants have been found in even the most remote locations. To assess the global distribution and possible effects of such contaminants, the authors examined the tissues of two species of albatross collected from Midway Atoll in the central North Pacific Ocean. These birds have an extensive feeding range covering much of the subtropical and northern Pacific Ocean. Anthropogenic contaminants were found at relatively great concentrations in these birds. The sum of 19 polychlorinated biphenyl (PCB) congeners ranged from 177 ng/g wet weight in eggs to 2,750 ng/g wet weight in adult fat. Total toxic equivalents (TEQs) derived from polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) ranged from 17.2 to 297 pg/g wet weight in the same tissues, while the inclusion of TEQs from PCBs increased these values to 48.4 and 769 pg/g wet weight, respectively. While contaminant concentrations varied between species and tissues, the contaminant profile was relatively uniform. The profile of contaminants detected was unusual in that much of the TEQs was contributed by two pentachlorinated congeners (2,3,4,7,8-pentachlorinated dibenzo-p-dioxin), and the profiles of PCB congeners did not match known sources. When compared to other studies the concentrations detected in the Midway Atoll samples were near or above the thresholds known to cause adverse effects in other fish-eating bird species.

Correlation of lignites in the midway and Wilcox groups of southern Alabama and eastern Mississippi  

SciTech Connect

The Gulf Coast Paleogene section represents one of the world's most continuous records of cyclic nonmarine through marine sedimentation. Microfossil research has demonstrated the completeness of downdip marine sections; however, the continuity of updip, nonmarine, and marginal marine sections remains relatively uncertain. Lignites occur throughout the Gulf Coast low Paleogene, but to date have not been adequately characterized with the detail necessary for high-resolution correlation. Lignite characteristics, stratigraphic position within Paleogene depositional cycles, and their mode of origin can be used in correlating nonmarine deposits (highstand system tract) to downdip marine deposits (transgressive system tract). Samples were collected for east-central Mississippi and west-central Alabama and analyzed. Principle constituents, comprising over 50%, are inaperturate forms in Midway Group samples and tricolporate forms in Wilcox Group samples. Secondary components, 10-20%, of triporate and monolete/trilete forms occur in both groups. Triporate forms are approximately 25% more abundant in the Wilcox Group samples, whereas monolete/trilete forms remain relatively constant in both groups. Minor components ([le]5%) of bivesticulate, tricolpate, polycolpate, polyporate, and polycolporate forms are present, but show distinct percentage variations between each group. Inaperature forms are present only in the Midway Group and monoporate forms exist only in the Wilcox Group. These group-specific forms, combined with the differences in primary and secondary forms and abundances, allow samples to be formationally assigned base on palynomorpbic signature.

Dudresnaya babbittiana (Dumontiaceae, Gigartinales), a new red algal species from Midway Atoll, North Central Pacific  

Science Journals Connector (OSTI)

Dudresnaya babbittiana I.A. Abbott et McDermid, sp. nov., is described from subtidal habitats at Midway Atoll, among the westernmost reefs and lagoons and series of islets in the Hawaiian archipelago. The new species differs in size, habit, internal rhizoids and auxiliary-cell morphology from the two species that have been previously described from the high islands of Hawaii about 1 400 km to the southeast, D. hawaiiensis R.K.S. Lee and D. littleri I.A. Abbott. Closest affinities appear to be with D. capricornica Robins et Kraft from tropical eastern and western Australia, which differs in having a much greater abundance of medullary rhizoids, more consistently present and larger hexagonal crystals in central-axial cells, a far less regular alignment of surface cortical cells, and differently structured carpogonial and auxiliary-cell filaments.

Distribution patterns of polychlorinated biphenyl congeners in water, sediment and biota from Midway Atoll  

SciTech Connect

There are large gaps in the understanding of critical pathways of polychlorinated biphenyl (PCB) transfer from abiotic media into lower trophic level marine organisms and, subsequently to higher marine consumers, particularly for the North Pacific Ocean. In this study, twenty PCB congeners were quantified in surface water, sediment and tissues of marine biota taken from near-shore waters at Midway Atoll. PCB 138, 153, 180, and 187 were the most abundant congeners in all samples analyzed. Bioaccumulation was shifted in favor of higher chlorinated congeners in all species; only aquatic macrophytes displayed significant accumulation of lower chlorinated congeners. Non-ortho substituted congeners with toxic potency were below detection levels in the majority of species. Certain mono-ortho congeners, implicated in marine mammal toxicity, comprised only 4.5% of total congener load in potential forage species.

Metal levels in feathers of 12 species of seabirds from Midway Atoll in the northern Pacific Ocean  

Science Journals Connector (OSTI)

Seabirds are excellent subjects for examination of heavy metals because they are long-lived, feed at different distances from land, and exhibit different trophic levels. In this paper we compare the levels of lead, cadmium, mercury arsenic, chromium, manganese, selenium, and tin in the feathers of birds nesting on Midway Atoll in the northern Pacific Ocean. We test the null hypothesis that there are no interspecific differences in the levels of metals in the feathers of the adult black-footed albatross (Diomedea nigripes), Laysan albatross (Diomedea immutabilis), red-footed booby (Sula sula), great frigatebird (Fregata minor), Bonin petrel (Pterodroma hypoleuca), Christmas shearwater (Puffinus nativitatis), red-tailed tropicbird (Phaethon rubricauda), wedge-tailed shearwater (Puffinus pacificus), brown noddy (Anous stolidus), sooty tern (Sterna fuscata), grey-backed tern (Sterna lunata), and white tern (Gygis alba), and young of some of these species. There were interspecific differences in the levels of all metals for adults. Christmas shearwater had the highest levels of lead, cadmium, selenium and manganese, but the second lowest levels of mercury. In general, metal levels were the lowest in the smallest species (white tern), but were not the highest in the largest species (black-footed albatross), except for manganese, arsenic and mercury. There was a high variance in metal levels among adults for some species, but not for others. White tern adults were variable for lead, while Christmas shearwaters were variable for lead and cadmium. Compared to the means for metals in other birds generally (after Burger, 1993), Christmas shearwaters had higher levels of lead, white terns, brown noddy, Christmas shearwater, frigatebirds and Laysan albatrosses had higher levels of cadmium, and bonin petrel, wedge-tailed shearwater, tropicbirds, frigatebirds, red-footed boobies, and both albatrosses had higher levels of mercury. Whereas the means for lead and cadmium were below the known effects levels, some individuals had levels high enough to cause adverse effects in the birds. The mean values for mercury in Bonin petrel, red-tailed tropicbird, and black-footed albatross were higher than the levels known to cause adverse reproductive and behavioral effects.

Paleoseismic investigations of the Paintbrush Canyon fault in southern Midway Valley, Yucca Mountain, Nevada: Preliminary results  

SciTech Connect

Trench mapping in southern Midway Valley provides evidence of multiple surface-faulting events on a western splay of the Paintbrush Canyon fault during the middle to late Pleistocene. The 6-m-wide fault zone exposed in the trench strikes N30-45E and dips steeply ([approximately]78[degree]) to the west, although some shears within the zone dip to the east. Tertiary volcanic bedrock is exposed only on the footwall block within the trench. Unconsolidated colluvial and eolian deposits are present in the hanging-wall block and above bedrock in the footwall block. These deposits tentatively are assigned, respectively, mid Pleistocene and late Pleistocene ages based on correlations with surficial map units in Midway Valley. Three to five displacement events are inferred based on faulted colluvial and eolian deposits, and scarp-derived colluvial wedges. Total cumulative dip-slip displacement of the oldest middle Pleistocene subunit is estimated to be about 170 to 270 cm. The dip-slip displacement associated with the youngest event is about 15 cm. The earlier displacements are estimated to have produced between 40 and 85 cm of dip-slip displacement per event. The most recent event occurred after deposition of late Pleistocene colluvium deposited against the fault scarp but before deposition of an overlying hillslope-derived colluvium of probable late pleistocene age. Based on the preliminary results of the authors study, the middle to late Quaternary rate of dip-slip displacement is approximately 0.01 m/kyr or less. Ongoing work, including soil-stratigraphic studies and numerical dating of deposits, should better constrain the timing and a rate of faulting along this western splay of the Paintbrush Canyon fault.

Paleocene benthonic foraminiferal biostratigraphy, paleobiogeography and paleoecology of Atlantic—Tethyan regions: Midway-type fauna  

Science Journals Connector (OSTI)

The stratigraphic, geographic and bathymetric distribution of some Paleocene benthonic foraminiferal assemblages have been studied in the Tethyan and circum-Atlantic regions within the framework of planktonic foraminiferal zones. Although some species appear to be restricted to either the Tethyan-European area or to the western Atlantic, the majority of species are amphi-Atlantic and Tethyan in distribution. The cosmopolitan distribution is attributed to more equitable climatic conditions (lower polar—equatorial thermal gradient) and warmer, more uniform thermal structure of the oceans and different paleogeographic and paleo-oceanographic conditions. Two main distinct depth-controlled benthonic foraminiferal assemblages (exclusive of the shallow-warm water Tethyan carbonate assemblage) have been recognized in the Paleocene. The continental shelf fauna, termed here the “Midway-type fauna” (MF) is characterized by species of Cibicidoides alleni (Plummer) = propria Brotzen, howelli (Toulmin), succedens (Brotzen), Anomalinoides [acuta (Plummer), midwayensis (Plummer)], Gavelinella [danica (Brotzen), neelyi (Jennings)], and Osangularia plummerae Brotzen, as well as various lagenids (nodosariids, lenticulinids, vaginulinids), polymorphinids and textulariids. A lower continental slope and abyssal plain fauna, termed here the “Velasco-type fauna” (VF), is characterized by, amongst others, Gavalinella [beccariiformis (White), rubiginosa (Cushman), velascoensis (Cushman)], Nuttallides truempy (Nuttall), Nuttallinella florealis (Cushman), velascoensisZ (Cushman)], (Cushman), Aragonia velascoensis (Cushman), nodosariids (N. velascoensis Cushman, Dentalina limbata d'Orbigny), various agglutinated forms [Gaudryina pyramidata Cushman, Tritaxia aspera (Cushman), Dorothia ex. gr. oxycona trinitatensis (Cushman and Renz)], and various gyroidinids and buliminids. Pleuriostomellids and stilostomellids are quantitatively rare and unimportant until the Middle—Late Eocene. This paper discusses the biostratigraphy and biogeography of the “Midway-type fauna”.

Hydroxylated and methylsulfonyl polychlorinated biphenyl metabolites in albatrosses from Midway Atoll, North Pacific Ocean  

SciTech Connect

Concentrations of hydroxylated metabolites of polychlorinated biphenyls (PCBs) (OH-PCBs) and methylsulfonyl metabolites of PCBs (MeSO{sub 2}-PCBs) were determined in plasma and liver of albatrosses collected from the Midway Atoll in the central North Pacific Ocean. The mean total concentrations of OH-PCBs in plasma of Laysan albatrosses (Diomedea immutabilis) and black-footed albatrosses (Diomedea nigripes) were 11.5 and 27.1 ng/g wet weight, respectively. Total concentrations of OH-PCBs were only one- to fivefold less than those of total PCBs. 4-hydroxy-2,2{prime},3,4{prime},5,5{prime},6-heptachlorinated biphenyl and 4-hydroxy-2,2{prime},3,4{prime},5,5{prime}-hexachlorinated biphenyl were the predominant polychlorinated biphenylols, constituting 70 to 90% of the total OH-PCBs. Concentrations of MeSO{sub 2}-PCBs in liver were between 10.6 and 77 ng/g, lipid weight, approximately 250 times less than those of total PCBs. The MeSO{sub 2}-PCBs congeners retained in the liver were dominated by those having the methylsulfonyl group in the 3-position.

Evaluation of the location and recency of faulting near prospective surface facilities in Midway Valley, Nye County, Nevada  

SciTech Connect

Evaluation of surface faulting that may pose a hazard to prospective surface facilities is an important element of the tectonic studies for the potential Yucca Mountain high-level radioactive waste repository in southwestern Nevada. For this purpose, a program of detailed geologic mapping and trenching was done to obtain surface and near-surface geologic data that are essential for determining the location and recency of faults at a prospective surface-facilities site located east of Exile Hill in Midway Valley, near the eastern base of Yucca Mountain. The dominant tectonic features in the Midway Valley area are the north- to northeast-trending, west-dipping normal faults that bound the Midway Valley structural block-the Bow Ridge fault on the west side of Exile Hill and the Paint-brush Canyon fault on the east side of the valley. Trenching of Quaternary sediments has exposed evidence of displacements, which demonstrate that these block-bounding faults repeatedly ruptured the surface during the middle to late Quaternary. Geologic mapping, subsurface borehole and geophysical data, and the results of trenching activities indicate the presence of north- to northeast-trending faults and northwest-trending faults in Tertiary volcanic rocks beneath alluvial and colluvial sediments near the prospective surface-facilities site. North to northeast-trending faults include the Exile Hill fault along the eastern base of Exile Hill and faults to the east beneath the surficial deposits of Midway Valley. These faults have no geomorphic expression, but two north- to northeast-trending zones of fractures exposed in excavated profiles of middle to late Pleistocene deposits at the prospective surface-facilities site appear to be associated with these faults. Northwest-trending faults include the West Portal and East Portal faults, but no disruption of Quaternary deposits by these faults is evident. The western zone of fractures is associated with the Exile Hill fault. The eastern zone of fractures is within Quaternary alluvial sediments, but no bedrock was encountered in trenches and soil pits in this part of the prospective surface facilities site; thus, the direct association of this zone with one or more bedrock faults is uncertain. No displacement of lithologic contacts and soil horizons could be detected in the fractured Quaternary deposits. The results of these investigations imply the absence of any appreciable late Quaternary faulting activity at the prospective surface-facilities site.

Electron transfer via a midway molecule as seen in primary processes in photosynthesis; a new process describable as superexchange or sequential in mutually opposite limits  

Science Journals Connector (OSTI)

Electron transfer (ET) mediated by a midway molecule should be described as a process new in itself, not in terms of direct ET between two molecules as a two-step sequential or a unistep superexchange mechanism. They describe only mutually opposite limits (not working in parallel as often assumed) that the reorganization time of phonons at the midway state is respectively much shorter or longer than the lifetime of an electron therein, when this state has energies comparable to the donor and acceptor states. We can obtain the rate constant of the ET by perturbational expansion in electronic coupling.

Distribution patterns of polychlorinated biphenyl congeners in water, sediment and biota from Midway Atoll (North Pacific Ocean)  

Science Journals Connector (OSTI)

To increase our understanding of critical pathways of polychlorinated biphenyl (PCB) transfer from abiotic media into marine organisms, this study quantified 20 PCB congeners in surface water, sediment and tissues of marine biota (macrophytes, snails, urchins, bivalves, sea cucumbers, fishes) taken from Midway Atoll. \\{PCBs\\} 138, 153, 170, 180 and 187 were the most abundant congeners in all samples analysed. Distribution of PCB congeners was shifted in favour of higher (hexa- and above) chlorinated congeners in all species; only aquatic macrophytes displayed significant bioaccumulation of lower (tri- and tetra-) chlorinated congeners. Evidence is presented for the differential metabolism of congeners by marine species. Non-ortho substituted congeners (PCBs 77, 126) with elevated toxic potency were not present at significant levels in the sampled species.

Abstract Concentrations of legacy organochlorine pesticides (OCPs), including dichlorodiphenyltrichloroethane (DDT) and its metabolites (e.g., DDE and DDD), and hexachlorocyclohexanes (HCHs) were determined in 111 soil samples from the Midway Atoll. \\{OCPs\\} were found in all samples analyzed, with predominance of ?-HCH, p,p?-DDD and p,p?-DDT. The total concentrations ranged from 0 to 127 ng g? 1 with a median concentration of 17 ng g? 1 for \\{HCHs\\} and 1.4 to 643 ng g? 1 with a median concentration of 168 ng g? 1 for DDTs. The possible degradation pathways and potential sources of \\{DDTs\\} and \\{HCHs\\} were investigated. The total concentrations of \\{DDTs\\} and \\{HCHs\\} were used to evaluate the cancer risk probabilities in humans via ingestion, dermal contact and inhalation of soil particles. Very low cancer risk was found in all soil samples caused by ?DDTs and ?HCHs.

Summary and evaluation of existing geological and geophysical data near prospective surface facilities in Midway Valley, Yucca Mountain Project, Nye County, Nevada; Yucca Mountain Site Characterization Project  

SciTech Connect

Midway Valley, located at the eastern base of the Yucca Mountain in southwestern Nevada, is the preferred location of the surface facilities for the potential high-level nuclear waste repository at Yucca Mountain. One goal in siting these surface facilities is to avoid faults that could produce relative displacements in excess of 5 cm in the foundations of the waste-handling buildings. This study reviews existing geologic and geophysical data that can be used to assess the potential for surface fault rupture within Midway Valley. Dominant tectonic features in Midway Valley are north-trending, westward-dipping normal faults along the margins of the valley: the Bow Ridge fault to the west and the Paintbrush Canyon fault to the east. Published estimates of average Quaternary slip rates for these faults are very low but the age of most recent displacement and the amount of displacement per event are largely unknown. Surface mapping and interpretive cross sections, based on limited drillhole and geophysical data, suggest that additional normal faults, including the postulated Midway Valley fault, may exist beneath the Quaternary/Tertiary fill within the valley. Existing data, however, are inadequate to determine the location, recency, and geometry of this faulting. To confidently assess the potential for significant Quaternary faulting in Midway Valley, additional data are needed that define the stratigraphy and structure of the strata beneath the valley, characterize the Quaternary soils and surfaces, and establish the age of faulting. The use of new and improved geophysical techniques, combined with a drilling program, offers the greatest potential for resolving subsurface structure in the valley. Mapping of surficial geologic units and logging of soil pits and trenches within these units must be completed, using accepted state-of-the-art practices supported by multiple quantitative numerical and relative age-dating techniques.

Drag force on a circular cylinder midway between two parallel plates at Part 2: moving uniformly (numerical and experimental)  

Science Journals Connector (OSTI)

To contribute to the determination of the hydrodynamic interactions between a long straight circular cylindrical particle and flow boundaries, we calculate the wall correction of the drag force exerted on a circular cylinder moving uniformly midway between two parallel plane walls, at very low Reynolds numbers. The wall correction factor is numerically and asymptotically investigated. Furthermore, we present a new experimental results for the drag force exerted on this straight circular cylinder. The Navier–Stokes and continuity equations are expressed in the stream function and vorticity formulation and are rewritten in an orthogonal system of curvilinear co-ordinates. These equations are solved with a finite-differences method. The accuracy of the numerical code is tested successfully through a comparison with theoretical and experimental results. In the lubrication regime the numerical calculations of the pressure and viscosity forces are in very good agreement with those obtained by asymptotic expansions. Combining the present results with those obtained in Poiseuille flow (Chem. Eng. Sci. 59 (15, part 1) (2004) 3215) we give the speed at which a force-free cylindrical particle would move with the fluid perpendicularly to it's axis between two planar walls in Poiseuille flow and corrected by wall effects.

Electron transfer via a midway molecule as seen in primary processes in photosynthesis: Superexchange or sequential, or unified?  

Science Journals Connector (OSTI)

A typical example of electron transfer (ET) mediated by a midway molecule is the initial ET in bacterial photosynthesis from the excited special pair (P?) to the bacteriopheophytin (BPh) mediated by the accessory chlorophyll monomer (BChl) stationed in between. It has been argued intensively whether this ET is sequential (where the state ?m? of P+?BChl??BPh exists as a real chemical intermediate) or superexchange (where it is passed as a quantum-mechanical virtual state). This ET is isomorphic to second-order optical processes (SOOP) where the initial state composed of an incoming photon and a matter is connected to the final state composed of an outgoing photon and a matter with phonons left excited through an intermediate state composed of a matter electronically excited without a photon. SOOP is a single process reducing to Raman scattering or an absorption-luminescence sequence in mutually opposite limits. Correspondingly this ET is also a single process, not composed of two coexisting parallel channels by superexchange and sequential ETs. It reduces to them only in mutually opposite limits determined by competition between the lifetime of an electron and the reorganization time of the medium at ?m?. The rate constant of this ET can be formulated by extending the formulation for SOOP. It can describe satisfactorily the initial ET in photosynthesis observed. We can predict, moreover, that superexchange ET should begin to manifest itself in a low-temperature region when ?m? is raised by several hundred cm?1 from its native position, with its validity range extending toward higher temperatures as ?m? is raised further.

Left ventricular incision midway between the mitral anulus and the stumps of the papillary muscles during mitral valve excision with or without rupture or aneurysmal formation: Analysis of 10 necropsy patients  

Science Journals Connector (OSTI)

Certain clinical and morphologic observations are described in 10 patients who had mitral valve replacement (MVR) and lacerations of the left ventricular (LV) free wall midway between the anulus of the mitral valve and the stumps of the LV papillary muscles. In five patients the lacerations led to LV free wall rupture, with immediate hemopericardium in two and delayed (2 to 4 days) rupture in the other three. Of the other five patients, three developed aneurysm of the LV free wall, the mouth of which was located midway between mitral anulus and papillary muscle stumps, the sites of the lacerations observed in the other seven patients. The remaining two patients had midway lacerations which produced neither rupture nor aneurysmal formation. The midway LV lacerations are considered the result of LV incisions made at the time of mitral valve excision, generally in a setting where the left-sided cardiac chambers were only mildly dilated or normal and the tips of the blades of the scissors may have been inadequately visualized during mitral excision. This complication can be prevented by leaving the posterior mitral leaflet and its attached chordae intact or by applying exquisite care during the mitral excision procedure, or both. LV midway rupture may be the most common cause of death early after MVR and operatively induced LV lacerations may lead to LV aneurysm late postoperatively.

Drag force on a circular cylinder midway between two parallel plates at very low Reynolds numbers—Part 1: Poiseuille flow (numerical)  

Science Journals Connector (OSTI)

At very low Reynolds numbers, we calculate the drag force exerted on a circular cylinder in cross flow fixed midway between two parallel plane walls which are fixed while the fluid experiences a Poiseuille profile at upstream and downstream. The drag wall correction factor is numerically investigated from a very weak interaction to the lubrication regime. The Navier–Stokes and continuity equations are expressed in the stream function and vorticity formulation and are rewritten in an orthogonal system of curvilinear co-ordinates. These equations are solved with using a finite differences method. The generation of the grid was carried out by the singularities method. We calculated the separate contributions of the pressure and viscous forces numerically. At very weak interactions, our numerical results are in good agreement with those obtained analytically by Harrison (Trans. Camb. Phil. Soc. 23 (1924) 71) and Faxèn (Proc. Roy. Swed. Acad. Eng. Sci. 187 (1946) 1). In the lubrication regime these numerical calculations are in very good agreement with those we carried out by asymptotic expansion. So that, the accuracy of the numerical code is tested. This analysis allowed us to show how that the pressure term prevails over the viscosity term in the lubrication regime. At very weak interaction, these forces have the same value.

Condensation of Self-assembled Lyotropic Chromonic Liquid Crystal Sunset Yellow in Aqueous Solutions Crowded with Polyethylene glycol and Doped with Salt  

E-Print Network (OSTI)

We use optical and fluorescence microscopy, densitometry, cryo-transmission electron microscopy (cryo-TEM), spectroscopy, and synchrotron X-ray scattering, to study the phase behavior of the reversible self-assembled chromonic aggregates of an anionic dye Sunset Yellow (SSY) in aqueous solutions crowded with an electrically neutral polymer polyethylene glycol (PEG) and doped with the salt NaCl. PEG causes the isotropic SSY solutions to condense into a liquid-crystalline region with a high concentration of SSY aggregates, coexisting with a PEG-rich isotropic (I) region. PEG added to the homogeneous nematic (N) phase causes separation into the coexisting N and I domains; the SSY concentration in the N domains is higher than the original concentration of PEG-free N phase. Finally, addition of PEG to the highly concentrated homogeneous N phase causes separation into the coexisting columnar hexagonal (C) phase and I phase. This behavior can be qualitatively explained by the depletion (excluded volume) effects that act at two different levels: at the level of aggregate assembly from monomers and short aggregates and at the level of inter-aggregate packing. We also show a strong effect of a monovalent salt NaCl on phase diagrams that is different for high and low concentrations of SSY. Upon the addition of salt, dilute I solutions of SSY show appearance of the condensed N domains, but the highly concentrated C phase transforms into a coexisting I and N domains. We suggest that the salt-induced screening of electric charges at the surface of chromonic aggregates leads to two different effects: (a) increase of the scission energy and the contour length of aggregates, and (b) decrease of the persistence length of SSY aggregates.

PHENIX recent heavy flavor results  

E-Print Network (OSTI)

Cold nuclear matter (CNM) effects provide an important baseline for the interpretation of data in heavy ion collisions. Such effects include nuclear shadowing, Cronin effect, and initial patron energy loss, and it is interesting to study the dependence on impact parameter and kinematic region. Heavy quark production is a good measurement to probe the CNM effects particularly on gluons, since heavy quarks are mainly produced via gluon fusions at RHIC energy. The PHENIX experiment has experiment has ability to study the CNM effects by measuring heavy quark production in $d$$+$Au collisions at variety of kinematic ranges. Comparisons of heavy quark production at different rapidities allow us to study modification of gluon density function in the Au nucleus depending on momentum fraction. Furthermore, comparisons to the results from heavy ion collisions (Au$+$Au and Cu$+$Cu) measured by PHENIX provide insight into the role of CNM effects in such collisions. Recent PHENIX results on heavy quark production are discussed.

Detecting heavy quarks  

SciTech Connect

In this exercise we examine the performance of a detector specifically configured to tag heavy quark (HQ) jets through direct observations of D-meson decays with a high resolution vertex detector. To optimize the performance of such a detector, we assume the small diamond beam crossing configuration as described in the 1978 ISABELLE proposal, giving a luminosity of 10/sup 32/ cm/sup -2/ sec/sup -1/. Because of the very large backgrounds from light quark (LQ) jets, most triggering schemes at this luminosity require high P/sub perpendicular to/ leptons and inevitably give missing neutrinos. If alternative triggering schemes could be found, then one can hope to find and calculate the mass of objects decaying to heavy quarks. A scheme using the high resolution detector will also be discussed in detail. The study was carried out with events generated by the ISAJET Monte Carlo and a computer simulation of the described detector system. (WHK)

Heavy Ions Heavy Ions Heavy ions used at the BASE Facility are accelerated in the form of "cocktails," named because of the fact that several heavy ions with the same mass-to-charge ratio are sent into the Cyclotron, which accelerates the ions while acting as a precision mass separator. The Control Room Operator then uses Cyclotron frequency to select only the desired ion, a process that takes about 2 minutes. We provide four standard cocktails: 4.5, 10, 16, and 30 MeV/nucleon. Depending on the cocktail, LETs from 1 to 100 MeV/(mg/cm^2) and flux levels of up to 1E7 ions/cm2-sec are available. Parts are tested in our vacuum chamber, and can be remotely positioned horizontally, vertically, or rotationally (y and z axes) with the motion table. An alignment laser is available to ensure the part is in the center of the beam. Mounting hardware is readily available. 12xBNC (F-F), 2x25-pin D (F-M or M-F), 4x40-pin flat ribbon (M-M), 4x50-pin flat ribbon (M-M), 12xSMA (F-F), and 2xEthernet vacuum feedthroughs are mounted upon request. (The 4x40-pin and 4x50-pin flat ribbon connectors are wired straight across, so you will need a F-F adapter to correct the pin numbers to normal.) Holes are provided through the cave shielding blocks for connecting additional test equipment, with a distance of approximately 10 feet from vacuum feedthrough to the top of the shielding block.

Utah Heavy Oil Program  

SciTech Connect

The Utah Heavy Oil Program (UHOP) was established in June 2006 to provide multidisciplinary research support to federal and state constituents for addressing the wide-ranging issues surrounding the creation of an industry for unconventional oil production in the United States. Additionally, UHOP was to serve as an on-going source of unbiased information to the nation surrounding technical, economic, legal and environmental aspects of developing heavy oil, oil sands, and oil shale resources. UHOP fulGilled its role by completing three tasks. First, in response to the Energy Policy Act of 2005 Section 369(p), UHOP published an update report to the 1987 technical and economic assessment of domestic heavy oil resources that was prepared by the Interstate Oil and Gas Compact Commission. The UHOP report, entitled 'A Technical, Economic, and Legal Assessment of North American Heavy Oil, Oil Sands, and Oil Shale Resources' was published in electronic and hard copy form in October 2007. Second, UHOP developed of a comprehensive, publicly accessible online repository of unconventional oil resources in North America based on the DSpace software platform. An interactive map was also developed as a source of geospatial information and as a means to interact with the repository from a geospatial setting. All documents uploaded to the repository are fully searchable by author, title, and keywords. Third, UHOP sponsored Give research projects related to unconventional fuels development. Two projects looked at issues associated with oil shale production, including oil shale pyrolysis kinetics, resource heterogeneity, and reservoir simulation. One project evaluated in situ production from Utah oil sands. Another project focused on water availability and produced water treatments. The last project considered commercial oil shale leasing from a policy, environmental, and economic perspective.

Heavy oil transportation by pipeline  

SciTech Connect

Worldwide there are a number of pipelines used to transport heavy crude oils. The operations are facilitated in a variety of ways. For example, the Alyeska pipeline is an insulated pipeline transporting warm oil over 800 miles. This 48-inch line experiences limited heat loss due to the insulation, volume of oil contained, and heat gain due to friction and pumping. Some European trunk lines periodically handle heavy and waxy crudes. This is achieved by proper sizing of batches, following waxy crudes with non-waxy crudes, and increased use of scrapers. In a former Soviet republic, the transportation of heavy crude oil by pipeline has been facilitated by blending with a lighter Siberian crude. The paper describes the pipeline transport of heavy crudes by Interprovincial Pipe Line Inc. The paper describes enhancing heavy oil transportation by emulsion formation, droplet suspension, dilution, drag reducing agents, and heating.

Managing Inventories of Heavy Actinides  

SciTech Connect

The Department of Energy (DOE) has stored a limited inventory of heavy actinides contained in irradiated targets, some partially processed, at the Savannah River Site (SRS) and Oak Ridge National Laboratory (ORNL). The 'heavy actinides' of interest include plutonium, americium, and curium isotopes; specifically 242Pu and 244Pu, 243Am, and 244/246/248Cm. No alternate supplies of these heavy actinides and no other capabilities for producing them are currently available. Some of these heavy actinide materials are important for use as feedstock for producing heavy isotopes and elements needed for research and commercial application. The rare isotope 244Pu is valuable for research, environmental safeguards, and nuclear forensics. Because the production of these heavy actinides was made possible only by the enormous investment of time and money associated with defense production efforts, the remaining inventories of these rare nuclear materials are an important part of the legacy of the Nuclear Weapons Program. Significant unique heavy actinide inventories reside in irradiated Mark-18A and Mark-42 targets at SRS and ORNL, with no plans to separate and store the isotopes for future use. Although the costs of preserving these heavy actinide materials would be considerable, for all practical purposes they are irreplaceable. The effort required to reproduce these heavy actinides today would likely cost billions of dollars and encompass a series of irradiation and chemical separation cycles for at least 50 years; thus, reproduction is virtually impossible. DOE has a limited window of opportunity to recover and preserve these heavy actinides before they are disposed of as waste. A path forward is presented to recover and manage these irreplaceable National Asset materials for future use in research, nuclear forensics, and other potential applications.

Relativistic Heavy Ion Collider Relativistic Heavy Ion Collider Photo of LINAC The Relativistic Heavy Ion Collider (RHIC) is a world-class particle accelerator at Brookhaven National Laboratory where physicists are exploring the most fundamental forces and properties of matter and the early universe. RHIC accelerates beams of particles (e.g., the nuclei of heavy atoms such as gold) to nearly the speed of light, and smashes them together to recreate a state of matter thought to have existed immediately after the Big Bang some 13.8 billion years ago. STAR and PHENIX, two large detectors located around the 2.4-mile-circumference accelerator, take "snapshots" of these collisions to reveal a glimpse of the basic constituents of visible matter, quarks and gluons.

Elliptic flow of heavy flavors  

E-Print Network (OSTI)

The propagation of charm and bottom quarks through a ellipsoidal domain of quark gluon plasma has been studied within the ambit of non-equilibrium statistical mechanics. Energy dissipation of heavy quarks by both radiative and collisional processes are taken in to account. The experimental data on the elliptic flow of the non-photonic electrons resulting from the semi-leptonic decays of hadrons containing heavy flavours has been reproduced with the same formalism that has been used earlier to reproduce the nuclear suppression factors. The elliptic flow of the non-photonic electron from heavy meson decays produced in nuclear collisions at LHC and low energy RHIC run have also been predicted.

Pionic Fusion of Heavy Ions  

Science Journals Connector (OSTI)

We report the first experimental observation of the pionic fusion of two heavy ions. The 12C(12C,24Mg)?0 and 12C(12C,24Na)?+ cross sections have been measured to be 208±38 and 182±84 pb, respectively, at Ecm=137MeV. This cross section for heavy-ion pion production, at an energy just 6 MeV above the absolute energy-conservation limit, constrains possible production mechanisms to incorporate the kinetic energy of the entire projectile-target system as well as the binding energy gained in fusion.

Spontaneous emission of heavy clusters  

Science Journals Connector (OSTI)

The lifetimes of some heavy nuclei relative to the spontaneous emission of various clusters heavier than the alpha particle are estimated with a model extended from the fission theory of alpha decay, showing that this phenomenon is a new manifestation of the nuclear shell structure. A greater probability is obtained for parent-heavy-cluster combinations leading to a magic or almost magic daughter nucleus. The analytical formula obtained allows one to handle a large number of cases to search for new kinds of radioactivities.

System to inject steam and produce oil from the same wellbore through downhole valve switching  

SciTech Connect

Various Downhole Equipment systems have been designed for typical applications in three California Oilfields,based on well data gathered from three different Operating Companies. The first system, applicable to a 2,000 ft deep reservoir (Monarch) a highly underpressured, unconsolidated sand of 200 ft net pay, located in the Midway-Sunset field, is based on the use of a new well. The second well configuration considered was the re-entry into an existing well equipped with a 7 inches casing and penetrating into two separate sandstone reservoirs, at normal pressures in the North Antelope Hills field. Only the bottom layer is presently in production through a gravel-packed 5.5 inch linear, while the upper zone is behind the cemented casing. The third case studied was the re-entry into an existing well equipped with an 8 5/8 inch casing, presently unperforated, into a thin under-pressured sand reservoir (Weber) in the Midway-Sunset field. All three California fields contain Heavy Oils of different but relatively high viscosities. A new class of potential applications of our new technology has also been considered: the recovery of Light Oil (> 20 API) by steam injection in under-pressured Carbonate reservoirs which lay at depths beyond the economic limit for conventional steam injection technology. The possibility of including this application in a Field Test proposal to the DOE, under the Class II Oil Program, is now under review by various Operators. A drilling contractor experienced in drilling multiple horizontal wells in Carbonate reservoirs and a team of reservoir engineers experienced in the recovery of Light Oil by steam in fractured reservoirs have expressed their interest in participating in such a joint Field Project. Laboratory tests on specific prototypes of Downhole Sealing Elements are underway.

Heavy oils (natural and refined)  

SciTech Connect

This section of the Petroleum and Coal review again contains discussions on the analysis of asphalts, bitumens, tars, and pitches as well as heavy natural and refined oils. The characterization of these heavy (high-boiling) materials impacts the way they are produced, their effect on the processing environment, and their suitability for various end products. The analysis of these heavy materials is becoming increasingly important as crude oil stocks get heavier and larger quantities of high-boiling materials are processed to derive clean lower boiling products. This review covers articles found in the literature in the last two years. This review will cover new or improved analytical procedures and applications to new sources of heavy oils. This review will be subdivided into individual separation or analytical techniques. Combined analytical techniques (e.g., GC-FT-IR) will be included under the technique most emphasized in the article. The review is categorized further by chromatographic techniques, spectroscopic techniques, thermal techniques, and miscellaneous. 71 refs.

Heavy oil production from Alaska  

SciTech Connect

North Slope of Alaska has an estimated 40 billion barrels of heavy oil and bitumen in the shallow formations of West Sak and Ugnu. Recovering this resource economically is a technical challenge for two reasons: (1) the geophysical environment is unique, and (2) the expected recovery is a low percentage of the oil in place. The optimum advanced recovery process is still undetermined. Thermal methods would be applicable if the risks of thawing the permafrost can be minimized and the enormous heat losses reduced. Use of enriched natural gas is a probable recovery process for West Sak. Nearby Prudhoe Bay field is using its huge natural gas resources for pressure maintenance and enriched gas improved oil recovery (IOR). Use of carbon dioxide is unlikely because of dynamic miscibility problems. Major concerns for any IOR include close well spacing and its impact on the environment, asphaltene precipitation, sand production, and fines migration, in addition to other more common production problems. Studies have indicated that recovering West Sak and Lower Ugnu heavy oil is technically feasible, but its development has not been economically viable so far. Remoteness from markets and harsh Arctic climate increase production costs relative to California heavy oil or Central/South American heavy crude delivered to the U.S. Gulf Coast. A positive change in any of the key economic factors could provide the impetus for future development. Cooperation between the federal government, state of Alaska, and industry on taxation, leasing, and permitting, and an aggressive support for development of technology to improve economics is needed for these heavy oil resources to be developed.

Open heavy flavor production at RHIC  

E-Print Network (OSTI)

The study of heavy flavor production in relativistic heavy ion collisions is an extreme experimental challenge but provides important information on the properties of the Quark-Gluon Plasma (QGP) created in Au+Au collisions at RHIC. Heavy-quarks are believed to be produced in the initial stages of the collision, and are essential on the understanding of parton energy loss in the dense medium created in such environment. Moreover, heavy-quarks can help to investigate fundamental properties of QCD in elementary p+p collisions. In this work we review recent results on heavy flavor production and their interaction with the hot and dense medium at RHIC.

Impact and future of heavy oil produciton  

SciTech Connect

Heavy oil resources are becoming increaingly important in meeting world oil demand. Heavy oil accounts for 10% of the worlds current oil production and is anticipated to grow significantly. Recent narrowing of the price margins between light and heavy oil and the development of regional heavy oil markets (production, refining and marketing) have prompted renewed investment in heavy oil. Production of well known heavy oil resources of Canada, Venezuela, United States, and elsewhere throughout the world will be expanded on a project-by-project basis. Custom refineries designed to process these heavy crudes are being expanded. Refined products from these crudes will be cleaner than ever before because of the huge investment. However, heavy oil still remains at a competitive disadvantage due to higher production, transportation and refining have to compete with other investment opportunities available in the industry. Expansion of the U.S. heavy oil industry is no exception. Relaxation of export restrictions on Alaskan North Slope crude has prompted renewed development of California's heavy oil resources. The location, resource volume, and oil properties of the more than 80-billion barrel U.S. heavy oil resource are well known. Our recent studies summarize the constraints on production, define the anticipated impact (volume, location and time frame) of development of U.S. heavy oil resources, and examines the $7-billion investment in refining units (bottoms conversion capacity) required to accommodate increased U.S. heavy oil production. Expansion of Canadian and Venezuelan heavy oil and tar sands production are anticipated to dramatically impact the U.S. petroleum market while displacing some imported Mideast crude.

The cross section for high energy muon bremsstrahlung on heavy atoms is calculated without the use of the Born approximation. It is shown that the correction to the Born approximation in the region of momentum transfers q of the order of ?c has the same order of magnitude as the well-known correction of Davies, Bethe, and Maximon. It is shown also that these corrections have different signs and nearly compensate each other.

Neglected heavy leptons at the LHC  

Science Journals Connector (OSTI)

New heavy leptons with standard model gauge couplings have well-determined cross sections for pair production. A standard pattern of mass mixing implies that the most likely decays are ???W?? and ???W?. Interestingly there have been no direct searches for heavy leptons with these decays at the LHC. However comparison with several multilepton searches allows us to set new limits on the heavy lepton masses. Three observed excesses in the signal regions prevent us from setting stronger limits.

Heavy flavor production in the STAR experiment  

E-Print Network (OSTI)

In this paper, recent STAR heavy flavor measurements in proton-proton and heavy-ion collisions are highlighted. We report studies of open charm mesons, reconstructed directly from hadronic decay products, and studies of electrons from semi-leptonic decays of heavy flavor hadrons. We also present J/$\\psi$ measurements via the di-electron decay channel at various collision systems and energies. In Au+Au collisions the energy dependence of J/$\\psi$ production measured at $\\sqrt{s_{NN}}$ = 39, 62.4 and 200 GeV is shown. Finally, prospects of heavy flavor measurements with the STAR detector upgrades are discussed.

Radical scavengers from heavy hydrocarbons  

SciTech Connect

The hydrogen-donating properties of some hydrocarbons form the basis for processes such as coal liquefaction and heavy oil upgrading. However, these hydrocarbons have seldom been used for other purposes, because their potential applications have not been well recognized. Research has indicated that these hydrogen-donating hydrocarbons can be used in important reactions as radical scavengers and have properties particular to those of pure hydrocarbons without functional groups containing heteroatoms. Over years of study researchers have found that pure hydrocarbons with radical-scavenging effects nearly as high as those in conventional hindered phenolic antioxidants can be produced from petroleum, and these hydrogen-donating hydrocarbons exhibit such effects even in oxidative atmospheres (i.e., they function as antioxidants). He has also shown that these mixtures have some properties particular to pure hydrocarbons without functional groups containing heteroatoms, and they`ve seen that a mechanism based on the steric effects appears when these hydrocarbons are used in heavy oil hydroprocessing. Hydrogen-donating hydrocarbons should be a viable resource in many applications. In this article, he presents radical-scavenging abilities, characteristics as pure hydrocarbons, and applications on the basis of the studies.

A Heavy Flavor Tracker for STAR  

SciTech Connect

We propose to construct a Heavy Flavor Tracker (HFT) for the STAR experiment at RHIC. The HFT will bring new physics capabilities to STAR and it will significantly enhance the physics capabilities of the STAR detector at central rapidities. The HFT will ensure that STAR will be able to take heavy flavor data at all luminosities attainable throughout the proposed RHIC II era.

Research and Development Opportunities for Heavy Trucks  

NLE Websites -- All DOE Office Websites (Extended Search)

1] 1] Introduction Heavy-duty long-haul trucks are critical to the movement of the Nation's freight. These vehicles, which currently consume about 10 percent of the Nation's oil, are characterized by high fuel consumption, fast market turnover, and rapid uptake of new technologies. Improving the fuel economy of Class 8 trucks will dramatically impact both fuel and cost savings. This paper describes the importance of heavy trucks to the Nation's economy, and its potential for fuel efficiency gains. Why Focus on Heavy Trucks? Large and Immediate Impact Investments in improving the fuel economy of heavy Class 8 trucks will result in large reduction in petroleum consumption within a short timeframe. While heavy-duty vehicles make up only 4% of the

Heavy photon search experiment at JLAB  

SciTech Connect

The Heavy Photon Search (HPS) experiment in Hall-B at Jefferson Lab will search for new heavy vector boson(s), aka 'heavy photons', in the mass range of 20 MeV/c{sup 2} to 1000 MeV/c{sup 2} using the scattering of high energy, high intensity electron beams off a high Z target. The proposed measurements will cover the region of parameter space favored by the muon g-2 anomaly, and will explore a significant region of parameter space, not only at large couplings (??/? > 10{sup ?7}), but also in the regions of small couplings, down to ??/??10{sup ?10}. The excellent vertexing capability of the Si-tracker uniquely enables HPS to cover the small coupling region. Also, HPS will search for heavy photons in an alternative to the e{sup +}e{sup ?} decay mode, in the heavy photon's decay to ?{sup +}??.

QCD mechanisms for heavy particle production  

SciTech Connect

For very large pair mass, the production of heavy quarks and supersymmetric particles is expected to be governed by ACD fusion subprocesses. At lower mass scales other QCD mechanisms such as prebinding distortion and intrinsic heavy particle Fock states can become important, possibly accounting for the anomalies observed for charm hadroproduction. We emphasize the importance of final-state Coulomb interactions at low relative velocity in QCD and predict the existence of heavy narrow four quark resonances (c c-bar u u-bar) and (cc c-bar c-bar) in ..gamma gamma.. reactions. Coherent QCD contributions are discussed as a contribution to the non-additivity of nuclear structure functions and heavy particle production cross sections. We also predict a new type of amplitude zero for exclusive heavy meson pair production which follows from the tree-graph structure of QCD. 35 refs., 8 figs., 1 tab.

Heavy Duty Vehicle Futures Analysis.  

SciTech Connect

This report describes work performed for an Early Career Research and Development project. This project developed a heavy-duty vehicle (HDV) sector model to assess the factors influencing alternative fuel and efficiency technology adoption. This model builds on a Sandia light duty vehicle sector model and provides a platform for assessing potential impacts of technological advancements developed at the Combustion Research Facility. Alternative fuel and technology adoption modeling is typically developed around a small set of scenarios. This HDV sector model segments the HDV sector and parameterizes input values, such as fuel prices, efficiencies, and vehicle costs. This parameterization enables sensitivity and trade space analyses to identify the inputs that are most associated with outputs of interest, such as diesel consumption and greenhouse gas emissions. Thus this analysis tool enables identification of the most significant HDV sector drivers that can be used to support energy security and climate change goals.

Heavy quark physics from SLD  

SciTech Connect

This report covers preliminary measurements from SLD on heavy quark production at the Z{sup 0}, using 150,000 hadronic Z{sup 0} decays accumulated during the 1993-1995 runs. A measurement of R{sub b} with a lifetime double tag is presented. The high electron beam polarization of the SLC is employed in the direct measurement of the parity-violating parameters A{sub b} and A{sub c} by use of the left-right forward-backward asymmetry. The lifetimes of B{sup +} and B{sup 0} mesons have been measured by two analyses. The first identifies semileptonic decays of B mesons with high (p,p{sub t}) leptons; the second analysis isolates a sample of B meson decays with a two-dimensional impact parameter tag and reconstructs the decay length and charge using a topological vertex reconstruction method.

Helioseismic limit on heavy element abundance  

E-Print Network (OSTI)

Primary inversions of accurately measured solar oscillation frequencies coupled with the equations of thermal equilibrium and other input physics, enable us to infer the temperature and hydrogen abundance profiles inside the Sun. These profiles also help in setting constraints on the input physics as well as on heavy element abundance in the solar core. Using different treatments of plasma screening for nuclear reaction rates, limits on the cross-section of proton-proton nuclear reaction as a function of heavy element abundance in the solar core are obtained and an upper limit on heavy element abundance in the solar core is also derived from these results.

Method for cutting steam heat losses during cyclic steam injection of wells. Second quarterly report  

SciTech Connect

The Midway-Sunset Field (CA) is the largest Heavy Oil field in California and steam injection methods have been successfully used for more than 30 years to produce the Heavy Oil from many of its unconsolidated sand reservoirs. In partnership with another DOE/ERIP grantee, our Company has acquired an 80 ac. lease in the SE part of this field, in order to demonstrate our respective technologies in the Monarch sand, of Miocene Age, which is one of the reservoirs targeted by the DOE Class 3 Oil Program. This reservoir contains a 13 API oil, which has a much higher market value, as a Refinery Feedstock, than the 5 to 8 API Vaca Tar, used only as road paving material. This makes it easier to justify the required investment in a vertical well equipped with two horizontal drainholes. The economic viability of such a project is likely to be enhanced if Congress approves the export to Japan of a portion of the 27 API (1% Sulfur) AK North Slope oil, which currently is landed in California in preference to lighter and sweeter Far East imported crudes. This is a major cause of the depressed prices for California Heavy Oil in local refineries, which have reduced the economic viability of all EOR methods, including steam injection, in California. Two proposals, for a Near-Term (3 y.) and for a Mid-Term (6 y.) project respectively, were jointly submitted to the DOE for Field Demonstration of the Partners` new technologies under the DOE Class 3 Oil Program. The previous design of a special casing joint for the Oxnard field well was reviewed and adapted to the use of existing Downhole Hardware components from three suppliers, instead of one. The cost of drilling and completion of a well equipped with two horizontal drainholes was re-evaluated for the conditions prevailing in the Midway Sunset field, which are more favorable than in the Oxnard field, leading to considerable reductions in drilling rig time and cost.

Heavy metals in Antarctic organisms  

SciTech Connect

To evaluate levels of essential (zinc and copper) and non-essential (mercury and cadmium) heavy metals, 34 species of organisms from different areas close to the Antarctic Peninsula were analysed. These included algae, filter-feeders, omnivorous invertebrates and vertebrates. Mercury was not detected, while cadmium was found in the majority of organisms analysed (detection limit was 0.05 ppm for both metals). The highest cadmium concentration was observed in the starfish Odontaster validus. Anthozoans, sipunculids and nudibranchs showed maximum levels of zinc, while the highest copper level was found in the gastropod Trophon brevispira. Mercury and cadmium levels in fishes were below the detection limit. Concentrations of essential and non-essential metals in birds were highest in liver followed by muscle and eggs. Cadmium and mercury levels in muscle of southern elephant seals were above the detection limit, whereas in Antarctic fur seals they were below it. The objective of the study was to gather baseline information for metals in Antarctic Ocean biota that may be needed to detect, measure and monitor future environmental changes. 46 refs., 7 figs., 8 tabs.

Water issues associated with heavy oil production.  

SciTech Connect

Crude oil occurs in many different forms throughout the world. An important characteristic of crude oil that affects the ease with which it can be produced is its density and viscosity. Lighter crude oil typically can be produced more easily and at lower cost than heavier crude oil. Historically, much of the nation's oil supply came from domestic or international light or medium crude oil sources. California's extensive heavy oil production for more than a century is a notable exception. Oil and gas companies are actively looking toward heavier crude oil sources to help meet demands and to take advantage of large heavy oil reserves located in North and South America. Heavy oil includes very viscous oil resources like those found in some fields in California and Venezuela, oil shale, and tar sands (called oil sands in Canada). These are described in more detail in the next chapter. Water is integrally associated with conventional oil production. Produced water is the largest byproduct associated with oil production. The cost of managing large volumes of produced water is an important component of the overall cost of producing oil. Most mature oil fields rely on injected water to maintain formation pressure during production. The processes involved with heavy oil production often require external water supplies for steam generation, washing, and other steps. While some heavy oil processes generate produced water, others generate different types of industrial wastewater. Management and disposition of the wastewater presents challenges and costs for the operators. This report describes water requirements relating to heavy oil production and potential sources for that water. The report also describes how water is used and the resulting water quality impacts associated with heavy oil production.

Low NOx combustion system for heavy oil  

SciTech Connect

As a result of the increasing demand for white oil as one of countermeasures for pollution control and as a fuel for motor vehicle, coupled with the increasing import of heavy crude oil, heavy oils such as asphalt and distillation residue have become surplus in Japan. It is difficult by the conventional low NOx technology to control the NOx emission from the industrial small and medium capacity boilers, which use heavy oil as their fuels. The authors have been developing and improving NOx control technologies for boilers such as low NOx burners, two-stage combustion methods and so on. They have developed a new combustion system for heavy oil, which generates less NOx and soot than conventional systems, by applying the knowledge, obtained in the course of their development of Coal Partial Combustor (CPC). The conventional low NOx combustion method for oil firing boilers has been developed based on decreasing the flame temperature and delaying the combustion reaction. In the system, however, the heavy oil shall be combusted in the intense reducing atmosphere at the high flame temperature between 1,500 C and 1,600 C, and then the combustions gas shall be cooled and oxidized by two-stage combustion air. With this system, NOx emission can be suppressed below 100ppm (converted as O{sub 2}=4%).

Economic feasibility of biochemical processes for the upgrading of crudes and the removal of sulfur, nitrogen, and trace metals from crude oil -- Benchmark cost establishment of biochemical processes on the basis of conventional downstream technologies. Final report FY95  

SciTech Connect

During the past several years, a considerable amount of work has been carried out showing that microbially enhanced oil recovery (MEOR) is promising and the resulting biotechnology may be deliverable. At Brookhaven National Laboratory (BNL), systematic studies have been conducted which dealt with the effects of thermophilic and thermoadapted bacteria on the chemical and physical properties of selected types of crude oils at elevated temperatures and pressures. Current studies indicate that during the biotreatment several chemical and physical properties of crude oils are affected. The oils are (1) emulsified; (2) acidified; (3) there is a qualitative and quantitative change in light and heavy fractions of the crudes; (4) there are chemical changes in fractions containing sulfur compounds; (5) there is an apparent reduction in the concentration of trace metals; and (6) the qualitative and quantitative changes appear to be microbial species dependent; and (7) there is a distinction between biodegraded and biotreated oils. The downstream biotechnological crude oil processing research performed thus far is of laboratory scale and has focused on demonstrating the technical feasibility of downstream processing with different types of biocatalysts under a variety of processing conditions. Quantitative economic analysis is the topic of the present project which investigates the economic feasibility of the various biochemical downstream processes which hold promise in upgrading of heavy crudes, such as those found in California, e.g., Monterey-type, Midway Sunset, Honda crudes, and others.

Fluid catalytic cracking of heavy petroleum fractions  

SciTech Connect

A process is claimed for fluid catalytic cracking of residuum and other heavy oils comprising of gas oil, petroleum residue, reduced and whole crudes and shale oil to produce gasoline and other liquid products which are separated in various streams in a fractionator and associated vapor recovery equipment. The heat from combustion of coke on the coked catalyst is removed by reacting sulfur-containing coke deposits with steam and oxygen in a separate stripper-gasifier to produce a low btu gas stream comprising of sulfur compounds, methane, carbon monoxide, hydrogen, and carbon dioxide at a temperature of from about 1100/sup 0/F. To about 2200/sup 0/F. The partially regenerated catalyst then undergoes complete carbon removal in a regeneration vessel. The regenerated catalyst is recycled for re-use in the cracking of heavy petroleum fractions. The liquid products are gasoline, distillates, heavy fuel oil, and light hydrocarbons.

High energy heavy ions: techniques and applications  

SciTech Connect

Pioneering work at the Bevalac has given significant insight into the field of relativistic heavy ions, both in the development of techniques for acceleration and delivery of these beams as well as in many novel areas of applications. This paper will outline our experiences at the Bevalac; ion sources, low velocity acceleration, matching to the synchrotron booster, and beam delivery. Applications discussed will include the observation of new effects in central nuclear collisions, production of beams of exotic short-lived (down to 1 ..mu..sec) isotopes through peripheral nuclear collisions, atomic physics with hydrogen-like uranium ions, effects of heavy ''cosmic rays'' on satellite equipment, and an ongoing cancer radiotherapy program with heavy ions. 39 refs., 6 figs., 1 tab.

Heavy Ion Physics at the LHC  

E-Print Network (OSTI)

The first Pb-Pb collisions at the LHC are little more than a year away. This paper discusses some of the exciting measurements which the experiments will be able to perform in the very first run, even with modest luminosity, and gives a very short overview of some of the most interesting ones attainable with more extended runs. The dedicated Heavy-Ion experiment ALICE, but also ATLAS and CMS, experiments optimized for p-p collisions, are ready and eager to make best use of the nuclear beams in the LHC as soon as they will be available. The main specificities of the three detectors for Heavy-Ion collisions will also be briefly addressed in this paper. I will try to show that already the first results obtainable with Heavy-Ion beams at the LHC will qualify it as a discovery machine, capable to provide fundamental new insight to our knowledge of high-density QCD matter.

Canadian operators boost heavy oil production  

SciTech Connect

Recent technological advances in slurry pipelining, horizontal wells, and thermal recovery techniques have made recovery of Canadian heavy oil resources more economical. In addition, reduced government royalties have made investment in these difficult reservoirs more attractive. As a result, activity has increased in heavy-oil fields in Alberta and Saskatchewan. This paper review the various oil sand recovery projects under development in the area and the current government policies which are helping to develop them. The paper also provides brief descriptions of the equipment and technologies that have allowed a reduced cost in the development. Items discussed include surface mining techniques, horizontal drilling, reservoir engineering techniques, separation processes, and thermal recovery.

Heavy quark diffusion from the lattice  

SciTech Connect

We study the diffusion of heavy quarks in the quark gluon plasma using the Langevin equations of motion and estimate the contribution of the transport peak to the Euclidean current-current correlator. We show that the Euclidean correlator is remarkably insensitive to the heavy quark diffusion coefficient and give a physical interpretation of this result using the free streaming Boltzmann equation. However if the diffusion coefficient is smaller than {approx}1/({pi}T), as favored by RHIC phenomenology, the transport contribution should be visible in the Euclidean correlator. We outline a procedure to isolate this contribution.

Heavy quarks in the jet calculus  

Science Journals Connector (OSTI)

In this paper we explore a method for treating heavy quarks such as c and b quarks within the jet calculus. These quarks are differentiated from the more common u, d, and s quarks by the requirement that the gluons never branch into heavy-quark pairs during the jet development. We compute and discuss the charmed-quark "propagators"; the x distribution of colorless clusters containing a charmed quark, a noncharmed antiquark, and gluons; and the mass distribution of the parent partons giving rise to these colorless clusters.

Towards Heavy Fermions in Europium Intermetallic Compounds  

NLE Websites -- All DOE Office Websites (Extended Search)

Towards Heavy Fermions in Towards Heavy Fermions in Europium Intermetallic Compounds Towards Heavy Fermions in Europium Intermetallic Compounds Print Wednesday, 29 July 2009 00:00 For decades, intermetallic compounds of rare-earth metals have been favorite systems of the research community studying strong electron correlations in solids. Nowadays rare-earth intermetallics are often treated as model systems for studies of zero-temperature quantum critical phase transitions, since heavy-fermion rare-earth compounds (in which the electron effective mass is orders of magnitude larger than the bare electron mass) have provided the clearest evidence for these continuous phase transitions, which are controlled by such parameters as chemical composition, magnetic field, and pressure, rather than temperature. A new study of a europium-based compound by an international team led by researchers from the Technische Universität Dresden in Germany hints that this compound could join well-known compounds of cerium, ytterbium, and uranium as a new material suitable for research on quantum critical transitions. This finding is exciting, since physicists hope that the use of a new material will give an additional degree of freedom for researching quantum critical behavior.

Boltzmann equation for heavy ion collisions  

Science Journals Connector (OSTI)

The sensitivity of inclusive observables in heavy ion collisions to the nuclear equation of state can be tested with the Boltzmann equation. We solve the Boltzmann equation, including mean field and Pauli blocking effects, by a method that follows closely the cascade model. We find that the inclusive pion production is insensitive to the nuclear equation of state, contrary to recent claims.

HEAVY AND THERMAL OIL RECOVERY PRODUCTION MECHANISMS  

SciTech Connect

This technical progress report describes work performed from April 1 through June 30, 2002, for the project ''Heavy and Thermal Oil Recovery Production Mechanisms.'' We investigate a broad spectrum of topics related to thermal and heavy-oil recovery. Significant results were obtained in the areas of multiphase flow and rock properties, hot-fluid injection, improved primary heavy oil recovery, and reservoir definition. The research tools and techniques used are varied and span from pore-level imaging of multiphase fluid flow to definition of reservoir-scale features through streamline-based history-matching techniques. Briefly, experiments were conducted to image at the pore level matrix-to-fracture production of oil from a fractured porous medium. This project is ongoing. A simulation studied was completed in the area of recovery processes during steam injection into fractured porous media. We continued to study experimentally heavy-oil production mechanisms from relatively low permeability rocks under conditions of high pressure and high temperature. High temperature significantly increased oil recovery rate and decreased residual oil saturation. Also in the area of imaging production processes in laboratory-scale cores, we use CT to study the process of gas-phase formation during solution gas drive in viscous oils. Results from recent experiments are reported here. Finally, a project was completed that uses the producing water-oil ratio to define reservoir heterogeneity and integrate production history into a reservoir model using streamline properties.

Heavy metal removal and recovery using microorganisms  

SciTech Connect

Microorganisms -- bacteria, fungi, and microalgae -- can accumulate relatively large amounts of toxic heavy metals and radionuclides from the environment. These organisms often exhibit specificity for particular metals. The metal content of microbial biomass can be a substantial fraction of total dry weight with concentration factors (metal in dry biomass to metal in solution) exceeding one million in some cases. Both living and inert (dead) microbial biomass can be used to reduce heavy metal concentrations in contaminated waters to very low levels -- parts per billion and even lower. In many respects (e.g. specificity, residual metal concentrations, accumulation factors, and economics) microbial bioremoval processes can be superior to conventional processes, such as ion exchange and caustic (lime or hydroxide) precipitation for heavy metals removal from waste and contaminated waters. Thus, bioremoval could be developed to contribute to the clean-up of wastes at the Savannah River Site (SRS) and other DOE facilities. However, the potential advantages of bioremoval processes must still be developed into practical operating systems. A detailed review of the literature suggests that appropriate bioremoval processes could be developed for the SRS. There is great variability from one biomass source to another in bioremoval capabilities. Bioremoval is affected by pH, other ions, temperature, and many other factors. The biological (living vs. dead) and physical (immobilized vs. dispersed) characteristics of the biomass also greatly affect metal binding. Even subtle differences in the microbial biomass, such as the conditions under which it was cultivated, can have major effects on heavy metal binding.

Stress distribution under heavy haul transporters  

SciTech Connect

In a previous cited paper, comparisons were made between the relationship of maximum vertical compressive stress generated with depth by various vehicles, including an automobile, a fully-loaded 18-wheel tractor-trailer combination, a test-loaded 12-axle, 96-wheel heavy transporter trailer, and the transporter prime mover, also test loaded. This paper extends the usefulness of those comparisons by adding a 12-axle, 144-wheel heavy transporter trailer. The transporter is a one-and-one-half-wide hydraulic platform trailer test loaded to 110% of the loading from a Westinghouse steam generator. The total weight on the transporter trailer tires is just over 675 tons. This trailer will be used in an upcoming steam generator replacement project. In addition to examining the distribution of maximum vertical stress with depth, the paper looks at the variation of loading beneath the maximum loaded axle of the transporter at different depths.

Search for Heavy Resonances at the LHC  

E-Print Network (OSTI)

Numerous models beyond the Standard Model theory predict new heavy particles or high energy phenomena that would appear as heavy resonances in collider data. Such a signature was thus actively searched for by the ATLAS and CMS collaborations using the LHC 8 TeV proton-proton collisions. The most recent analyses using the full dataset (~ 20 fb-1) and probing a large variety of final states are reported in this article. No sign of new physics was discovered and the results are thus interpreted as exclusion limits in a model independent way or on various models based on the presence of extra-dimensions, a new strong sector or large symmetry groups.

Heavy-Quarkonia in the Star Experiment  

E-Print Network (OSTI)

Heavy Quarkonium states modifications in relativistic heavy ion collisions have been of great interest since the proposal by Matsui and Satz of J/psi suppression as a signature of Quark-Gluon Plasma (QGP) formation. Recent studies suggest that the excited states chi_c, psi(2S) and Upsilon(3S) melt sequentially[1,2] and the amount of observed suppression depends on the state and medium conditions. Therefore, this suppression pattern may be used as a probe of the medium temperature. In this work we present preliminary results on the charmonium and bottomnium measurements performed by the STAR experiment at RHIC for p+p and Cu+Cu collisions at sqrt(s_{NN})=200GeV

Jets in heavy ion collisions with ATLAS  

E-Print Network (OSTI)

The energy loss of high-p_T partons provides insight into the transport properties of the medium created in relativistic heavy ion collisions. Evidence for this energy loss was first experimentally established through observation of high-p_T hadron suppression at RHIC. More recently, measurements of fully reconstructed jets have been performed at the LHC. In this summary the latest experimental results from the ATLAS collaboration on jet suppression are presented. In particular the jet suppression in inclusive jet yields, path length dependence of the jet suppression, photon-jet and Z^0-jet correlations, heavy flavor suppression, and jet fragmentation are discussed. These results establish qualitative features of the jet quenching mechanism as experimental fact and provide constraints on models of jet energy loss.

Fragmentation in central collisions of heavy systems  

SciTech Connect

One of the goals of heavy ion reaction studies is to understand the fragmentation of hot nuclei. The LBL/GSI Plastic Ball detector system has been used to achieve a very high solid angle for detection of light and medium-heavy fragments emitted in 200 Mev/A Au + Au and Au + Fe reactions. The simultaneous measurement of almost all of the nucleons and nuclei resulting from each collision allows an estimation of the total charged particle multiplicity and hence the impact parameter. By choosing subsets of the data corresponding to a peripheral or central collision, the assumptions inherent in various models of nuclear fragmentation can be tested. 3 refs., 3 figs.

Quark condensate for various heavy flavors  

E-Print Network (OSTI)

The quark condensate is calculated within the world-line effective-action formalism, by using for the Wilson loop an ansatz provided by the stochastic vacuum model. Starting with the relation between the quark and the gluon condensates in the heavy-quark limit, we diminish the current quark mass down to the value of the inverse vacuum correlation length, finding in this way a 64%-decrease in the absolute value of the quark condensate. In particular, we find that the conventional formula for the heavy-quark condensate cannot be applied to the c-quark, and that the corrections to this formula can reach 23% even in the case of the b-quark. We also demonstrate that, for an exponential parametrization of the two-point correlation function of gluonic field strengths, the quark condensate does not depend on the non-confining non-perturbative interactions of the stochastic background Yang-Mills fields.

Heavy tetraquarks production at the LHC  

Science Journals Connector (OSTI)

In the current work, spectroscopy and the possibility of observation at the LHC of tetraquarks composed of four heavy quarks are discussed. The tetraquarks concerned are T4c=[cc][c¯c¯], T4b=[bb][b¯b¯], and T2[bc]=[bc][b¯c]¯. By solving the nonrelativistic Schrödinger equation, masses of these states are found with the hyperfine splitting that is accounted for. It is shown that masses of tensor tetraquarks T4c(2++) and T2[bc](2++) are high enough to observe these states as peaks in the invariant mass distributions of heavy quarkonia pairs in pp?T4c+X?2J/?+X, pp?T2[bc]+X?2Bc+X and pp?T2[bc]+X?J/??(1S)+X channels, while T4b is under the threshold of decay into a vector bottomonia pair.

Heavy quarkonium: progress, puzzles, and opportunities  

E-Print Network (OSTI)

A golden age for heavy quarkonium physics dawned a decade ago, initiated by the confluence of exciting advances in quantum chromodynamics (QCD) and an explosion of related experimental activity. The early years of this period were chronicled in the Quarkonium Working Group (QWG) CERN Yellow Report (YR) in 2004, which presented a comprehensive review of the status of the field at that time and provided specific recommendations for further progress. However, the broad spectrum of subsequent breakthroughs, surprises, and continuing puzzles could only be partially anticipated. Since the release of the YR, the BESII program concluded only to give birth to BESIII; the $B$-factories and CLEO-c flourished; quarkonium production and polarization measurements at HERA, JLab, and the Tevatron matured; and heavy-ion collisions at RHIC have opened a window on the deconfinement regime. All these experiments leave legacies of quality, precision, and unsolved mysteries for quarkonium physics, and therefore beg for continuing ...

Co-processing of heavy oil  

SciTech Connect

In co-processing of petroleum and coal, the petroleum fraction may serve as the {open_quotes}liquefaction solvent,{close_quotes} or hydrogen donor, and the aromatics present in the coal liquid may serve as hydrogen {open_quotes}shuttlers{close_quotes} by efficiently transferring hydrogen moieties to places where they are most deficient. The important advantages of co-processing include the following: (1) upgrading of heavy petroleum in a reaction with coal and (2) conversion of coal to synthetic crudes which could be further upgraded to a premium liquid fuel. Co-processing of coal with petroleum, heavy crudes, and residues through catalytic hydrogenation or solvent extraction have been extensively investigated. The studies were typically conducted in the temperature range of 450{degrees}-500{degrees}C under pressurized hydrogen; catalysts are generally also added for hydroconversion of the feedstocks. However, relatively little has been reported in the literature regarding co-processing of coal with heavy petroleum by simple pyrolysis. In this study, co-processing of heavy oil and coal at relatively middle conditions was conducted without the complicating influences of pressurized hydrogen or catalysts. The resulted demonstrate that there is a synergism during co-processing of petroleum and coal. This synergism enhances both the yield and quality of the liquid products. In general, liquids from co-processing the mixture contain a higher content of alkane/alkene, neutral aromatics, lower content of monophenols, and other oxygen containing compounds as compared to the liquids from coal alone. The liquid from the mixture also contains a higher content of naphthenic carbon and naphthenic rings/molecules than those from coal liquid. This suggests that the product from the mixture can be easily upgraded to a premium quality fuel.

Lifecycle-analysis for heavy vehicles.  

SciTech Connect

Various alternative fuels and improved engine and vehicle systems have been proposed in order to reduce emissions and energy use associated with heavy vehicles (predominantly trucks). For example, oil companies have proposed improved methods for converting natural gas to zero-aromatics, zero-sulfur diesel fuel via the Fischer-Tropsch process. Major heavy-duty diesel engine companies are working on ways to simultaneously reduce particulate-matter and NOX emissions. The trend in heavy vehicles is toward use of lightweight materials, tires with lower rolling resistance, and treatments to reduce aerodynamic drag. In this paper, we compare the Mecycle energy use and emissions from trucks using selected alternatives, such as Fisher-Tropsch diesel fuel and advanced fuel-efficient engines. We consider heavy-duty, Class 8 tractor-semitrailer combinations for this analysis. The total life cycle includes production and recycling of the vehicle itself, extraction, processing, and transportation of the fuel itself, and vehicle operation and maintenance. Energy use is considered in toto, as well as those portions that are imported, domestic, and renewable. Emissions of interest include greenhouse gases and criteria pollutants. Angonne's Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation (GREET) model is used to generate per-vehicle fuel cycle impacts. Energy use and emissions for materials manufacturing and vehicle disposal are estimated by means of materials information from Argonne studies. We conclude that there are trade-offs among impacts. For example, the lowest fossil energy use does not necessarily result in lowest total energy use, and lower tailpipe emissions may not necessarily result in lower lifecycle emissions of all criteria pollutants.

In this work, we introduce a new technique to perform densitometric and multielemental analysis of samples at the same time using a simple detector with heavy ion micro-beams. It consists in the simultaneous analysis of X-rays induced in the sample and in a secondary target arranged behind the specimen. The X-rays originated in the secondary target are attenuated when crossing the specimen producing a radiographic image with a monochromatic source.

HEAVY AND THERMAL OIL RECOVERY PRODUCTION MECHANISMS  

SciTech Connect

This technical progress report describes work performed from October 1 through December 31, 2002 , for the project ''Heavy and Thermal Oil Recovery Production Mechanisms.'' In this project, a broad spectrum of research is undertaken related to thermal and heavy-oil recovery. The research tools and techniques used are varied and span from pore-level imaging of multiphase fluid flow to definition of reservoir-scale features through streamline-based history-matching techniques. During this period, experimental data regarding multidimensional imbibition was analyzed to obtain shape factors appropriate for dual-porosity simulation. It is shown that the usual assumption of constant, time-independent shape factors is incorrect. In other work, we continued to study the mechanisms by which oil is produced from fractured media at high pressure and high temperature. High temperature significantly increased the apparent wettability and affected water relative permeability of cores used in previous experiments. A phenomenological and mechanistic cause for this behavior is sought. Our work in the area of primary production of heavy oil continues with field cores and crude oil. On the topic of reservoir definition, work continued on developing techniques that integrate production history into reservoir models using streamline-based properties.

We continued to study the mechanisms by which oil is produced from fractured porous media at high pressure and high temperature. Temperature has a beneficial effect on recovery and reduces residual oil saturation. A new experiment was conducted on diatomite core. Significantly, we show that elevated temperature induces fines release in sandstone cores and this behavior may be linked to wettability. Our work in the area of primary production of heavy oil continues with field cores and crude oil.

Relativistic corrections to heavy quark fragmentation to S-wave heavy mesons  

Science Journals Connector (OSTI)

The relativistic corrections of order v2 to the fragmentation functions for the heavy quark to S-wave heavy quarkonia are calculated in the framework of the nonrelativistic quantum chromodynamics factorization formula. We derive the fragmentation functions by using the Collins-Soper definition in both the Feynman gauge and the axial gauge. We also extract them through the process Z0?Hqq¯ in the limit MZ/m??. We find that all results obtained by these two different methods and in different gauges are the same. We estimate the relative size of the relativistic corrections to the fragmentation functions.

The Heavy Photon Search Test Detector  

E-Print Network (OSTI)

The Heavy Photon Search (HPS), an experiment to search for a hidden sector photon in fixed target electroproduction, is preparing for installation at the Thomas Jefferson National Accelerator Facility (JLab) in the Fall of 2014. As the first stage of this project, the HPS Test Run apparatus was constructed and operated in 2012 to demonstrate the experiment's technical feasibility and to confirm that the trigger rates and occupancies are as expected. This paper describes the HPS Test Run apparatus and readout electronics and its performance. In this setting, a heavy photon can be identified as a narrow peak in the e$^+$e$^-$ invariant mass spectrum, above the trident background or as a narrow invariant mass peak with a decay vertex displaced from the production target, so charged particle tracking and vertexing are needed for its detection. In the HPS Test Run, charged particles are measured with a compact forward silicon microstrip tracker inside a dipole magnet. Electromagnetic showers are detected in a PbW0$_{4}$ crystal calorimeter situated behind the magnet, and are used to trigger the experiment and identify electrons and positrons. Both detectors are placed close to the beam line and split top-bottom. This arrangement provides sensitivity to low-mass heavy photons, allows clear passage of the unscattered beam, and avoids the spray of degraded electrons coming from the target. The discrimination between prompt and displaced e$^+$e$^-$ pairs requires the first layer of silicon sensors be placed only 10~cm downstream of the target. The expected signal is small, and the trident background huge, so the experiment requires very large statistics. Accordingly, the HPS Test Run utilizes high-rate readout and data acquisition electronics and a fast trigger to exploit the essentially 100% duty cycle of the CEBAF accelerator at JLab.

The Heavy Photon Search test detector  

The Heavy Photon Search (HPS), an experiment to search for a hidden sector photon in fixed target electroproduction, is preparing for installation at the Thomas Jefferson National Accelerator Facility (JLab) in the Fall of 2014. As the first stage of this project, the HPS Test Run apparatus was constructed and operated in 2012 to demonstrate the experiment's technical feasibility and to confirm that the trigger rates and occupancies are as expected. This paper describes the HPS Test Run apparatus and readout electronics and its performance. In this setting, a heavy photon can be identified as a narrow peak in the e+e- invariant mass spectrum, above the trident background or as a narrow invariant mass peak with a decay vertex displaced from the production target, so charged particle tracking and vertexing are needed for its detection. In the HPS Test Run, charged particles are measured with a compact forward silicon microstrip tracker inside a dipole magnet. Electromagnetic showers are detected in a PbW04 crystal calorimeter situated behind the magnet, and are used to trigger the experiment and identify electrons and positrons. Both detectors are placed close to the beam line and split top-bottom. This arrangement provides sensitivity to low-mass heavy photons, allows clear passage of the unscattered beam, and avoids the spray of degraded electrons coming from the target. The discrimination between prompt and displaced e+e? pairs requires the first layer of silicon sensors be placed only 10~cm downstream of the target. The expected signal is small, and the trident background huge, so the experiment requires very large statistics. Accordingly, the HPS Test Run utilizes high-rate readout and data acquisition electronics and a fast trigger to exploit the essentially 100% duty cycle of the CEBAF accelerator at JLab.

We have completed the next-to-leading order perturbative QCD corrections to the virtual-photon exclusive differential cross sections for heavy quark production in deep-inelastic electron-proton scattering, i.e. $e + P \\rightarrow Q + \\overline{Q} + X$. Using these results, we have computed distributions which are sensitive to correlations among the heavy quark, the heavy antiquark, and the associated jet. Some predictions for charm and bottom heavy quark production at the electron-proton collider HERA are presented.

Heavy Flavor Simplified Models at the LHC  

SciTech Connect

We consider a comprehensive set of simplified models that contribute to final states with top and bottom quarks at the LHC. These simplified models are used to create minimal search strategies that ensure optimal coverage of new heavy flavor physics involving the pair production of color octets and triplets. We provide a set of benchmarks that are representative of model space, which can be used by experimentalists to perform their own optimization of search strategies. For data sets larger than 1 fb{sup -1}, same-sign dilepton and 3b search regions become very powerful. Expected sensitivities from existing and optimized searches are given.

Non abelian hydrodynamics and heavy ion collisions  

SciTech Connect

The goal of the relativistic heavy ion collisions (RHIC) program is to create a state of matter where color degrees of freedom are deconfined. The dynamics of matter in this state, in spite of the complexities of quantum chromodynamics, is largely determined by the conservation laws of energy momentum and color currents. Therefore it is possible to describe its main features in hydrodynamic terms, the very short color neutralization time notwithstanding. In this lecture we shall give a simple derivation of the hydrodynamics of a color charged fluid, by generalizing the usual derivation of hydrodynamics from kinetic theory to the non abelian case.

Source dimensions in ultrarelativistic heavy ion collisions  

SciTech Connect

Recent experiments on pion correlations, interpreted as interferometric measurements of the collision zone, are compared with models that distinguish a prehadronic phase and a hadronic phase. The models include prehadronic longitudinal expansion, conversion to hadrons in local kinetic equilibrium, and rescattering of the produced hadrons. The longitudinal radius measured in collisions of 200 GeV/u sulfur nuclei on a heavy target require the existence of a prehadronic phase which converts to the hadronic phase at densities around 0.8 GeV/fm{sup 3}. The transverse radii cannot be reproduced without introducing more complex dynamics into the transverse expansion.

We investigate particle production in heavy-ion collisions at RHIC energies as function of incident energy, and centrality in a three-sources Relativistic Diffusion Model. Pseudorapidity distributions of produced charged hadrons in Au + Au and Cu + Cu collisions at sqrt(s_NN) = 19.6 GeV, 62.4 GeV, 130 GeV and 200 GeV show an almost equilibrated midrapidity source that tends to increase in size towards higher incident energy, and more central collisions. It may indicate quark-gluon plasma formation prior to hadronization.

Heavy quark diffusion in pre-equilibrium stage of heavy ion collisions  

E-Print Network (OSTI)

The drag and diffusion coefficients of the heavy quarks have been evaluated in the pre-equilibrium phase which is expected to be formed in the early stages of the evolving fire ball produced in heavy ion collisions at RHIC and LHC energies. The interaction of the probe with the gluon in the pre-equilibrium phase has been treated within the framework of perturbative QCD. For the pre-equilibrium gluon distribution function we have used the KLN and Classical Yang Mills(CYM) models. It is observed that the magnitude of both the transport coefficients have significant values in the pre-equilibrium phase and comparable to the magnitudes obtained for kinetically equilibrated gluonic system. However, these values are larger than the value estimated for a chemically equilibrated quark gluon plasma. The results may have significant impact on the experimental observable like the suppression and elliptic flow of single electron spectra originating from the decays of heavy mesons produced in heavy ion collisions at RHIC a...

Focus on Venezuelan heavy crude: refining margins  

SciTech Connect

Of six crudes refined in the US Gulf Coast, heavy Venezuelan crude Lagunillas (15/sup 0/ API) provides the best margin per barrel. Data for end of December 1983 and the first three weeks of January show that margins on all crudes are on the rise in this market, due to a turnaround in product prices. The lighter crudes are showing the greatest increase in Gross Product Worth. This is having a modest shrinking effect on the margin differential between light and heavy crudes in this market. The domestic crude West Texas Intermediate, at 40/sup 0/ API, provides the highest GPW in this crude slate sample, over US $31 per barrel, compared to GPW of under US $28 per barrel for Lagunillas. Still, as Lagunillas cost about US $8 less than does WTI, refiners with sufficient residue conversion capacity can be earning about US $3.50 more in margin per barrel than they can with WTI. Although few refiners would be using a 15/sup 0/ API crude exclusively for any length of time, heavier oil's inclusion in modern refiners' diets is enhancing their competitive position more than any other single factor. This issue of Energy Detente presents the fuel price/tax series and industrial fuel prices for January 1984 for countries of the Western Hemisphere.

HEAVY AND THERMAL OIL RECOVERY PRODUCTION MECHANISMS  

SciTech Connect

This technical progress report describes work performed from July 1 through September, 2003 for the project ''Heavy and Thermal Oil Recovery Production Mechanisms,'' DE-FC26-00BC15311. In this project, a broad spectrum of research is undertaken related to thermal and heavy-oil recovery. The research tools and techniques span from pore-level imaging of multiphase fluid flow to definition of reservoir-scale features through streamline-based history-matching techniques. During this period, work focused on completing project tasks in the area of multiphase flow and rock properties. The area of interest is the production mechanisms of oil from porous media at high temperature. Temperature has a beneficial effect on oil recovery and reduces residual oil saturation. Work continued to delineate how the wettability of reservoir rock shifts from mixed and intermediate wet conditions to more water-wet conditions as temperature increases. One mechanism for the shift toward water-wet conditions is the release of fines coated with oil-wet material from pore walls. New experiments and theory illustrate the role of temperature on fines release.

Electromagnetic Heating Methods for Heavy Oil Reservoirs  

SciTech Connect

The most widely used method of thermal oil recovery is by injecting steam into the reservoir. A well-designed steam injection project is very efficient in recovering oil, however its applicability is limited in many situations. Simulation studies and field experience has shown that for low injectivity reservoirs, small thickness of the oil-bearing zone, and reservoir heterogeneity limits the performance of steam injection. This paper discusses alternative methods of transferring heat to heavy oil reservoirs, based on electromagnetic energy. They present a detailed analysis of low frequency electric resistive (ohmic) heating and higher frequency electromagnetic heating (radio and microwave frequency). They show the applicability of electromagnetic heating in two example reservoirs. The first reservoir model has thin sand zones separated by impermeable shale layers, and very viscous oil. They model preheating the reservoir with low frequency current using two horizontal electrodes, before injecting steam. The second reservoir model has very low permeability and moderately viscous oil. In this case they use a high frequency microwave antenna located near the producing well as the heat source. Simulation results presented in this paper show that in some cases, electromagnetic heating may be a good alternative to steam injection or maybe used in combination with steam to improve heavy oil production. They identify the parameters which are critical in electromagnetic heating. They also discuss past field applications of electromagnetic heating including technical challenges and limitations.

Jet Reconstruction in Heavy Ion Collisions  

E-Print Network (OSTI)

Measurements of strong suppression of inclusive hadron distributions and di-hadron correlations at high $p_{T}$, while providing evidence for partonic energy loss, also suffer from geometric biases due to the competition of energy loss and fragmentation. The measurements of fully reconstructed jets is expected to lack these biases as the energy flow is measured independently of the fragmentation details. In this article, we review the recent results from the heavy ion collisions collected by the STAR experiment at RHIC on direct jet reconstruction utilizing the modern sequential recombination and cone jet reconstruction algorithms together with their background subtraction techniques. In order to assess the jet reconstruction biases a comparison with the jet cross section measurement in $\\sqrt{s}=200$ GeV p+p collisions scaled by the number of binary nucleon-nucleon collisions to account for nuclear geometric effects is performed. Comparison of the inclusive jet cross section obtained in central Au+Au events with that in $p+p$ collisions, published previously by STAR, suggests that unbiased jet reconstruction in the complex heavy ion environment indeed may be possible.

Removal of Heavy Metals from Industrial Effluent Using Bacteria  

E-Print Network (OSTI)

Industrial development results in the generation of industrial effluents, and if untreated results in water, sediment and soil pollution. (Fakayode and Onianwa, 2002 ? Fakayode, 2005). Industrial wastes and emission contain toxic and hazardous substances, most of which are detrimental to human health (Jimena et al.,2008 ? Ogunfowokan et al.,2005 ? Rajaram et al.,2008). The key pollutants include heavy metals, chemical wastes and oil spills etc. Heavy metal resistant bacteria have significant role in bioremediation of heavy metals in wastewater. The objective of this work is to study the role of bacteria in removing the heavy metals present in the industrial effluent.Five effluent samples out of nine were selected for this study due to high content of heavy metals. The heavy metals Hg and Cu were removed by Bacillus sp. The average Hg reduction was 45 % and Cu reduction was recorded as 62%. The heavy metals Cd, As and Co were removed by Pseudomonas sp. The average Cd reduction was 56%, average As reduction was 34 % and average Co reduction was recorded as 53%. The heavy metals Cd and Cu were removed by Staphylococcus sp. The average Cd reduction was 44 % and average Cu reduction was recorded as 34 %.

Light-front heavy-quark effective theory and heavy-meson bound states  

Science Journals Connector (OSTI)

The heavy-quark effective theory is developed on the light front. Based on this effective theory, a light-front heavy-meson bound state with definite spin and parity is constructed. Within the effective theory, the Isgur-Wise function is derived in terms of the asymptotic light-front bound state amplitudes in the limit mQ??; the result is a general expression for arbitrary recoil velocities. With the asymptotic form of the BSW amplitudes, the Isgur-Wise function is given by ?(v?v?)=1/v?v?. The slope at the zero-recoil point is ?2=-??(1)=1, in excellent agreement with the recent CLEO result of ?2=1.01±0.15±0.09.

Bulk viscosity in heavy ion collision  

E-Print Network (OSTI)

The effect of a temperature dependent bulk viscosity to entropy density ratio~($\\zeta/s$) along with a constant shear viscosity to entropy density ratio~($\\eta/s$) on the space time evolution of the fluid produced in high energy heavy ion collisions have been studied in a relativistic viscous hydrodynamics model. The boost invariant Israel-Stewart theory of causal relativistic viscous hydrodynamics is used to simulate the evolution of the fluid in 2 spatial and 1 temporal dimension. The dissipative correction to the freezeout distribution for bulk viscosity is calculated using Grad's fourteen moment method. From our simulation we show that the method is applicable only for $\\zeta/s<0.004$.

A relativistic cascade for heavy ion collisions  

SciTech Connect

Au on Au collisions at the BNL/AGS (11.6 GeV-A/c) are expected to produce a short-lived state of matter at high baryon density. If the baryons reach sufficiently high density, they may produce a quark-gluon plasma (QGP). The signals from a QGP phase may be difficult to distinguish from those of ordinary hadronic matter. The authors have constructed a relativistic cascade (ARC) for hadrons in an attempt to model the dynamics of ordinary hadronic matter in a heavy ion collision, in the hopes that deviations from the cascade results may indicate new physics. In this contribution the authors discuss the formation of high baryon density matter, and its effect on antiproton production.

HEAVY ION PHYSICS WITH THE ATLAS DETECTOR.  

SciTech Connect

Soon after the LHC is commissioned with proton beams the ATLAS experiment will begin studies of Pb-Pb collisions with a center of mass energy of {radical}s{sub NN} = 5.5 TeV. The ATLAS program is a natural extension of measurements at RHIC in a direction that exploits the higher LHC energies and the superb ATLAS calorimeter and tracking coverage. At LHC energies, collisions will be produced with even higher energy density than observed at RHIC. The properties of the resulting hot medium can be studied with higher energy probes, which are more directly interpreted through modification of jet properties emerging from these collisions, for example. Other topics which are enabled by the 30-fold increase in center of mass energy include probing the partonic structure of nuclei with hard photoproduction (in UltraPeripheral collisions) and in p-Pb collisions. Here we report on evaluation of ATLAS capabilities for Heavy Ion Physics.

Lightweight Composite Materials for Heavy Duty Vehicles  

SciTech Connect

The main objective of this project is to develop, analyze and validate data, methodologies and tools that support widespread applications of automotive lightweighting technologies. Two underlying principles are guiding the research efforts towards this objective: • Seamless integration between the lightweight materials selected for certain vehicle systems, cost-effective methods for their design and manufacturing, and practical means to enhance their durability while reducing their Life-Cycle-Costs (LCC). • Smooth migration of the experience and findings accumulated so far at WVU in the areas of designing with lightweight materials, innovative joining concepts and durability predictions, from applications to the area of weight savings for heavy vehicle systems and hydrogen storage tanks, to lightweighting applications of selected systems or assemblies in light–duty vehicles.

Exhaust emissions from heavy-duty vehicles  

Science Journals Connector (OSTI)

Exhaust emission tests were conducted on 20 heavy-duty vehicles. These test vehicles were Euro 1 and Euro 2 compliant and included coaches, and trucks ranging from 7.5 to 38 tonne vehicles. The vehicles were tested over the European 13-mode and the FIGE engine dynamometer tests, with some of the vehicles repeat tested using an ultra low sulphur diesel fuel (ULSD). A single test vehicle was tested over a selection of real world driving cycles. In general, Euro 2 vehicles demonstrated lower emissions than Euro 1 vehicles. The ULSD produced large decreases in the emissions of CO and PM with a smaller decrease in NOx. Although Euro 2 vehicles produced less mass of particulate, the number of particles emitted significantly increased when compared to Euro 1. The FIGE and the Truck cycles produced the lowest and similar emission rates, while the bus cycle produced much higher levels, reflecting the importance of vehicle operation on emissions.

Heavy Baryon Mixing in Chiral Perturbation Theory  

E-Print Network (OSTI)

We discuss the SU(3) and heavy quark spin-symmetry breaking mixing between the Xi_c and Xi'_c charmed baryons. Chromomagnetic hyperfine interactions are the leading source of spin-symmetry breaking and together with the SU(3) breaking mass differences between the lightest pseudo-Goldstone bosons gives the leading contribution to the mixing. Such contributions are computed in chiral perturbation theory and compared to quark model expectations. We also compute the leading contribution to the semileptonic decay Xi_b -> Xi'_c l nu at zero recoil, and find that it is an order of magnitude smaller than naive power counting would suggest. It appears that Xi_b -> Xi'_c l nu is dominated by incalculable counterterms, and we discuss the implications for quark models based on the essential role of hyperfine interactions.

Rhenium alloying of tungsten heavy alloys  

SciTech Connect

Alloying experiments were performed using rhenium additions to a classic 90 mass % tungsten heavy alloy. The mixed-powder system was liquid phase sintered to full density at 1500 C in 60 min The rhenium-modified alloys exhibited a smaller grain size, higher hardness, higher strength, and lower ductility than the unalloyed system. For an alloy with a composition of 84W-6Re-8Ni-2Fe, the sintered density was 17, 4 Mg/m{sup 3} with a yield strength of 815 MPa, tensile strength of 1180 MPa, and elongation to failure of 13%. This property combination results from the aggregate effects of grain size reduction and solid solution hardening due to rhenium. In the unalloyed system these properties require post-sintering swaging and aging; thus, alloying with rhenium is most attractive for applications where net shaping is desired, such as by powder injection molding.

Supersymmetric heavy Higgs bosons at the LHC  

Science Journals Connector (OSTI)

The search for heavy Higgs bosons is an essential step in the exploration of the Higgs sector and in probing the supersymmetric parameter space. This paper discusses the constraints on the MA and tan?? parameters derived from the bounds on the different decay channels of the neutral H and A bosons accessible at the LHC, in the framework of the phenomenological minimal supersymmetric extension of the standard model. The implications from the present LHC results and the expected sensitivity of the 14 TeV data are discussed in terms of the coverage of the [MA-tan??] plane. New channels becoming important at 13 and 14 TeV for low values of tan?? are characterized in terms of their kinematics and the reconstruction strategies. The effect of QCD systematics, SUSY loop effects and decays into pairs of SUSY particles on these constraints are discussed in details.

LHC Results on Charmonium in Heavy Ions  

E-Print Network (OSTI)

In heavy-ion collisions at high energies, the quantum chromodynamics (QCD) predicts the production of the deconfined quark-gluon plasma (QGP) state. Quarkonia ($c\\bar{c}$ or $b\\bar{b}$ bound states) are a useful means to probe QGP and to investigate the behavior of QCD under the high parton-density environment. Up to now, the large hadron collider (LHC) at CERN provided two runs for PbPb collisions at $\\sqrt{s_{NN}}$ = 2.76 TeV in the years 2010 and 2011. The ALICE, ATLAS, and CMS experiments at LHC have analyzed the yields and spectra of the $J/\\psi$ and $\\Upsilon$ families. In this article, we review particularly the recent charmonium results in PbPb collisions at LHC from the 2010 run.

New Type of Accelerator for Heavy Ions  

Science Journals Connector (OSTI)

A new device, called the heavy ion plasma accelerator (HIPAC), which may be capable of accelerating ions of any atomic number to energies sufficient to overcome the nuclear Coulomb barrier, is described. A closed potential well is created by filling a toroidal vacuum chamber with electrons; the electrons are contained by a magnetic field whose intensity is so low that its effect on the ions can be neglected. Ions are both accelerated and trappend in the well; the trapping effect allows sufficient time for the ions to become highly stripped by electron impact. The very large ion energies that can be achieved in this way would allow a wide variety of nuclear reactions to be studied, including inverse fission. The present primitive state of development of the HIPAC is described, and the future prospects assessed.

Hadron Production in Heavy Ion Collisions  

SciTech Connect

Heavy ion collisions are an ideal tool to explore the QCD phase diagram. The goal is to study the equation of state (EOS) and to search for possible in-medium modifications of hadrons. By varying the collision energy a variety of regimes with their specific physics interest can be studied. At energies of a few GeV per nucleon, the regime where experiments were performed first at the Berkeley Bevalac and later at the Schwer-Ionen-Synchrotron (SIS) at GSI in Darmstadt, we study the equation of state of dense nuclear matter and try to identify in-medium modifications of hadrons. Towards higher energies, the regime of the Alternating Gradient Synchrotron (AGS) at the Brookhaven National Laboratory (BNL), the Super-Proton Synchrotron (SPS) at CERN, and the Relativistic Heavy Ion Collider (RHIC) at BNL, we expect to produce a new state of matter, the Quark-Gluon Plasma (QGP). The physics goal is to identify the QGP and to study its properties. By varying the energy, different forms of matter are produced. At low energies we study dense nuclear matter, similar to the type of matter neutron stars are made of. As the energy is increased the main constituents of the matter will change. Baryon excitations will become more prevalent (resonance matter). Eventually we produce deconfined partonic matter that is thought to be in the core of neutron stars and that existed in the early universe. At low energies a great variety of collective effects is observed and a rather good understanding of the particle production has been achieved, especially that of the most abundantly produced pions and kaons. Many observations can be interpreted as time-ordered emission of various particle species. It is possible to determine, albeit model dependent, the equation of state of nuclear matter. We also have seen indications, that the kaon mass, especially the mass of the K{sup +}, might be modified by the medium created in heavy ion collisions. At AGS energies and above, emphasis shifts towards different aspects. Lattice QCD calculations predict the transition between a Quark-Gluon Plasma and a hadronic state at a critical temperature, T{sub c}, of about 150 to 190 MeV at vanishing baryon density. The energy density at the transition point is about 1:0 GeV/fm{sup 3}. It is generally assumed that chiral symmetry restoration happens simultaneously. In the high-energy regime, especially at RHIC, a rich field of phenomena [3] has revealed itself. Hot and dense matter with very strong collectivity has been created. There are indications that collectivity develops at the parton level, i.e. at a very early stage of the collision, when the constituents are partons rather than hadrons. Signs of pressure driven collective effects are our main tool for the study of the EOS. There are also strong indications that in the presence of a medium hadronization occurs through the process of quark coalescence and not through quark fragmentation, the process dominant for high-energy p+p reactions. We limit this report to the study of hadrons emitted in heavy ion reactions. The report is divided into two parts. The first part describes the phenomena observed from hadrons produced at low energies, whereas the second part concentrates on the search for signs of a partonic state at high energies.

A Heavy Flavor Tracker for STAR  

SciTech Connect

The STAR Collaboration proposes to construct a state-of-the-art microvertex detector,the Heavy Flavor Tracker (HFT), utilizing active pixel sensors and silicon strip technology. The HFT will significantly extend the physics reach of the STAR experiment for precision measurement of the yields and spectra of particles containing heavy quarks. This will be accomplished through topological identification of D mesons by reconstruction of their displaced decay vertices with a precision of approximately 50 mu m in p+p, d+A, and A+A collisions. The HFT consists of 4 layers of silicon detectors grouped into two sub-systems with different technologies, guaranteeing increasing resolution when tracking from the TPC and the Silicon Strip Detector (SSD) towards the vertex of the collision. The Intermediate Silicon Tracker (IST), consisting of two layers of single-sided strips, is located inside the SSD. Two layers of Silicon Pixel Detector (PIXEL) are inside the IST. The PIXEL detectors have the resolution necessary for a precision measurement of the displaced vertex. The PIXEL detector will use CMOS Active Pixel Sensors (APS), an innovative technology never used before in a collider experiment. The APSsensors are only 50 mu m thick and at a distance of only 2.5 cm from the interaction point. This opens up a new realm of possibilities for physics measurements. In particular, a thin detector (0.28percent radiation length per layer) in STAR makes it possible to do the direct topological reconstruction of open charm hadrons down to very low pT by the identification of the charged daughters of the hadronic decay.

Heavy-ion collisions at the LHC  

Science Journals Connector (OSTI)

Abstract A new era in the study of high-energy nuclear collisions began when the CERN Large Hadron Collider (LHC) provided the first collisions of lead nuclei in late 2010. In the first three years of operation the ALICE, ATLAS and CMS experiments each collected Pb–Pb data samples of more than 50 ? b ? 1  at s NN = 2.76 TeV , exceeding the previously studied collision energies by more than an order of magnitude. These data have provided new insights into the properties of QCD matter under extreme conditions, with extensive measurements of soft particle production and newly accessible hard probes of the hot and dense medium. In this review, we provide a comprehensive overview of the results obtained in heavy-ion collisions at the LHC so far, with particular emphasis on the complementary nature of the observations by the three experiments. In particular, the combination of ALICE’s strengths at hadron identification, the strengths of ATLAS and CMS to make precise measurements of high p T  probes, and the resourceful measurements of collective flow by all of the experiments have provided a rich and diverse dataset in only a few years. While the basic paradigm established at RHIC — that of a hot, dense medium that flows with a viscosity to shear-entropy ratio near the predicted lower bound, and which degrades the energy of probes, such as jets, heavy-flavours and J / ? — is confirmed at the LHC, the new data suggest many new avenues for extracting its properties in detail.

Concentrations of Heavy Metals in Selected Tissues of Blue  

E-Print Network (OSTI)

Abstract: Persian Gulf supports diverse ecosystems and biota in need of remediation and protection and metal data from this region is needed. The levels of heavy metals (Fe, Hg, Ni and Pb) in tissues (hepatopancreas, muscle and exoskeleton) of blue swimming crab, Portunus pelagicus and sediments in the Persian Gulf coasts, south Iran were investigated. Heavy metals analysis was performed by Atomic Absorption Spectrophotometer. The concentration of heavy metals in sediments at all sampling stations occurs in descending order of Fe> Ni> Hg> Pb during both seasons. The distribution pattern of heavy metals in the tissues of crab and sediments was as follows: sediment> hepatopancreasn> muscle> exoskeleton. Maximum concentration of the total heavy metals in sediments and all tissues of P. pelagicus observes in Bahrekan station (Pheavy metals in the tissues of the crab P. pelagicus. In present study recorded that there was negligible differences in heavy metals levels between different seasons. Differences in heavy metals concentrations among the species is likely to have resulted from metal bioavailability, hydrodynamics of the environment, changes in tissue composition, stations of collection and sources of pollution within Persian Gulf.

The 273 heavy hydrocarbons in the database include branched/unbranched paraffins and olefins together with a variety of complex nonfused/fused aromatic and naphthenic compounds. A generalized one-parameter viscosity-temperature equation, log ({mu} + 0.8) = 100(0.01T){sup b}, is proposed (overall AAD {lt} 7-10%) for all heavy hydrocarbons in the database. For each hydrocarbon, an optimum value of parameter b is provided. It is shown that parameter b varies linearly with the logarithm of molar mass as well as the inverse of boiling temperature (at 10 mmHg). This important observation leads to the development of a predictive method for the liquid-phase viscosity of pure heavy hydrocarbons.

Bioremediation of soil contaminated with hydrocarbons and heavy metals  

SciTech Connect

This investigation showed that a soil contaminated with petroleum hydrocarbons and heavy metals had sufficient indigenous microbial activity for hydrocarbon biodegradation under nonlimiting conditions. Nutrient supplementation with nitrogen and phosphate, together with aeration, seemed to be the most important factors for enhancing biodegradation. Hydrocarbon biodegradation occurred to a much greater extent under aerobic than under anaerobic conditions. Biodegradation did, however, induce low pH conditions and thus caused high heavy-metal concentrations in the leachate. Anaerobic conditions inhibited hydrocarbon biodegradation with no subsequent drop in pH and low heavy-metal concentrations in the leachate. Thus, anaerobic conditions were shown to facilitate less metal mobility than low pH conditions. Air sparging did not cause a significant increase in biodegradation. Adsorption of heavy-fraction hydrocarbons (> C{sub 20}) to microorganisms and colloidal material in the leachate was suspected of facilitating mobility of these fractions and thus their subsequent detection in the leachate.

Classical simulations of heavy-ion collisions  

Science Journals Connector (OSTI)

We have carried out simulations of central collisions between two heavy ions by the classical molecular dynamics method. The ions used in these simulations are bound spheres of charged argon atoms, and the chosen mass numbers for the collisions are 108 on 108, 65 on 65, and 16 on 200. A few hundred collisions are studied for five energies chosen to span fusion-fission, multifragmentation, and total vaporization reactions. We have also studied the disassembly of hot liquid drops containing 216 and 130 particles. By comparing collisions and disassembly we establish the formation of equilibrated hot matter in the collisions. The density of the hot matter formed appears to be ?80% of the equilibrium density, and its temperature depends upon the beam energy. All the beam energy thermalizes in equal mass collisions; however, a large fraction of it is lost in pre-equilibrium emission in the asymmetric 16 on 200 collisions. Mass yields and energy spectra of the particles emitted in collisions and disassemblies are reported, and the role of the liquid-gas phase transition is discussed. The yield of small clusters having Ac<30 particles is approximately given by the & power law. The ?eff depends on the energy of the collision, and has a minimum value of ?1.7 as observed in nuclear fragmentation reactions.

Nuclear molecular configurations in heavy ion collisions  

SciTech Connect

The possibilities of nuclear molecular configurations in symmetric and asymmetric heavy ion collisions are investigated by choosing a proper parametrization for the molecule-like compound state. We treat the nucleus as a rotating liquid drop in terms of the elliptic lemniscatoid parametrization suggested by Royer and Remaud which describes all deformed shapes that occur during the process of fusion of two nuclei, starting from two touching spheres to a single one with the intermediate formation of a deep neck. Only one parameter ({ital s} for the symmetric and {ital s}{sub 1} for the conditional asymmetric case) is needed to define all the shapes encountered in the process. The shape has a neck as long as {ital s} or {ital s}{sub 1} is less than 1/ {radical}2 . In this parametrization, analytical expressions can be obtained for volume, surface, and moment of inertia while the Coulomb energy has to be evaluated numerically. The total energy of the system is calculated as a function of the parameter {ital s} or {ital s}{sub 1}, for various spins and if the stable shape corresponding to minimum energy is one with a neck, then it is concluded that the molecular configuration is possible. Our model yields results which are in good agreement with the experimental findings.

Biochemical processing of heavy oils and residuum  

SciTech Connect

During the past several decades, the petroleum industry has adjusted gradually to accommodate the changes in market product demands, government regulations, and the quality and cost of feedstock crude oils. For example, the trends show that the demand for distillate fuels, such as diesel, as compared to gasoline are increasing. Air-quality standards have put additional demand on the processing of heavier and higher sulfur feed stocks. Thus, the 1990 Clean Air Act amendments require the industry to produce greater quantities of oxygenated gasoline, and lower sulfur diesel and reformulated gasoline. Biochemical technology may play an important role in responding to these demands on the petroleum industry. Since oil is of biological origin, some biochemical reactions started at the beginning of its formation are still continuing in reservoirs on a geological time scale. Although these rates are very slow, many reactions can proceed readily under optimal conditions. This article will address some of the reactions that may be useful for processing heavy oils and refinery residuum. 6 refs., 2 figs., 3 tabs.

Heavy quarks and long-lived hadrons  

Science Journals Connector (OSTI)

In a recent Letter we reported on some work which led us to suggest the possibility of narrow spikes in the e+e- annihilation cross section into hadrons. In this paper, we discuss the theoretical infrastructure of this work more thoroughly, and improve and extend the calculations and experimental predictions. We examine a colored quark-gluon model of hadronic matter, with color an exact SU(3) gauge symmetry. In addition to the light quarks that make up ordinary hadrons, a heavy quark, such as the charmed c, is included. The narrow resonances recently discovered by the MIT-BNL and SLAC-LBL groups are interpreted as cc¯ bound states (orthocharmonium). In this energy range, the effective coupling has become small according to asymptotic freedom, and many aspects of the bound-state structure can be calculated. The existence of 0- (paracharmonium) states is predicted, and decay widths and mass splittings are estimated. The total e+e- cross section into hadrons is predicted to scale asymptotically, with an approach to scaling from above that can be calculated over a large energy range.

Flavor in heavy neutrino searches at the LHC

Heavy neutrinos at the TeV scale have been searched for at the LHC in the context of left-right models, under the assumption that they couple to the electron, the muon, or both. We show that current searches are also sensitive to heavy neutrinos coupling predominantly to the tau lepton, and present limits can significantly constrain the parameter space of general flavor mixing.

Heavy metal ions are potent inhibitors of protein folding  

SciTech Connect

Environmental and occupational exposure to heavy metals such as cadmium, mercury and lead results in severe health hazards including prenatal and developmental defects. The deleterious effects of heavy metal ions have hitherto been attributed to their interactions with specific, particularly susceptible native proteins. Here, we report an as yet undescribed mode of heavy metal toxicity. Cd{sup 2+}, Hg{sup 2+} and Pb{sup 2+} proved to inhibit very efficiently the spontaneous refolding of chemically denatured proteins by forming high-affinity multidentate complexes with thiol and other functional groups (IC{sub 50} in the nanomolar range). With similar efficacy, the heavy metal ions inhibited the chaperone-assisted refolding of chemically denatured and heat-denatured proteins. Thus, the toxic effects of heavy metal ions may result as well from their interaction with the more readily accessible functional groups of proteins in nascent and other non-native form. The toxic scope of heavy metals seems to be substantially larger than assumed so far.

Production and decay of heavy top quarks  

SciTech Connect

Experimental evidence indicates that the top quark exists and has a mass between 50 and 200 GeV/c{sup 2}. The decays of a top quark with a mass in this range are studied with emphasis placed on the mass region near the threshold for production of real W bosons. Topics discussed are: (1) possible enhancement of strange quark production when M{sub W} + m{sub s} < m{sub t} < M{sub W} + m{sub b}; (2) exclusive decays of T mesons to B and B{asterisk} mesons using the non-relativistic quark model; (3) polarization of intermediate W's in top quark decay as a source of information on the top quark mass. The production of heavy top quarks in an e{sup +}e{sup {minus}} collider with a center-of-mass energy of 2 TeV is studied. The effective-boson approximation for photons, Z{sup 0}'s and W's is reviewed and an analogous approximation for interfaces between photons and Z{sup 0}'s is developed. The cross sections for top quark pair production from photon-photon, photon-Z{sup 0}, Z{sup 0}Z{sup 0}, and W{sup +}W{sup {minus}} fusion are calculated using the effective-boson approximation. Production of top quarks along with anti-bottom quarks via {gamma}W{sup +} and Z{sup 0}W{sup +} fusion is studied. An exact calculation of {gamma}e{sup +} {yields} {bar {nu}}t{bar b} is made and compared with the effective-W approximation. 31 refs., 46 figs.

Hydrogen solubility in heavy oil systems: Experiments and modeling  

Science Journals Connector (OSTI)

Abstract Hydrogen solubility measurements in heavy oils are required in order to develop accurate process models. Nevertheless, these solubility measurements are challenging at elevated temperatures and pressures and the amount of data points is scarce in the literature. This paper presents measured hydrogen solubilities in heavy oil systems at a temperature range from 498 to 598 K and a pressure range from 2 to 11 MPa. The experiments were conducted with a continuous flow apparatus. One of the well-characterized heavy oil systems was a hydrocracked vacuum gas oil and the second system consisted of a modified vacuum residue from Urals crude and toluene. The modified vacuum residue and toluene mixtures were prepared gravimetrically (mass fractions of vacuum residue: 0.25, 0.34 and 0.50). The experiments demonstrated that increasing the partial pressure of hydrogen and temperature increased the hydrogen solubility. Another finding was that the amount of toluene in the system had great impact to the hydrogen solubility. Four modeling approaches were compared based on their predictions on the hydrogen solubility in heavy oil systems measured in this work and four heavy oils found from the literature. The chosen models were PC-SAFT, Peng–Robinson, a simple correlation based on the corresponding theory and a method based on the Scatchard–Hildebrand theory. PC-SAFT with applied a heavy oil characterization method and the correlation based on the corresponding theory were found to predict the hydrogen solubility equally well and accurately. The benefit of using PC-SAFT instead of the simple correlation is that with PC-SAFT, phase behavior of multicomponent systems can be predicted and other properties, such as densities, can be obtained simultaneously. Peng–Robinson with a single carbon number characterization method overestimated the hydrogen solubility in the studied heavy oils and the method based on the Scatchard–Hildebrand theory could model the hydrogen solubility well after parameter regression.

Heavy oil reservoirs recoverable by thermal technology. Annual report  

SciTech Connect

The purpose of this study was to compile data on reservoirs that contain heavy oil in the 8 to 25/sup 0/ API gravity range, contain at least ten million barrels of oil currently in place, and are non-carbonate in lithology. The reservoirs within these constraints were then analyzed in light of applicable recovery technology, either steam-drive or in situ combustion, and then ranked hierarchically as candidate reservoirs. The study is presented in three volumes. Volume I presents the project background and approach, the screening analysis, ranking criteria, and listing of candidate reservoirs. The economic and environmental aspects of heavy oil recovery are included in appendices to this volume. This study provides an extensive basis for heavy oil development, but should be extended to include carbonate reservoirs and tar sands. It is imperative to look at heavy oil reservoirs and projects on an individual basis; it was discovered that operators, and industrial and government analysts will lump heavy oil reservoirs as poor producers, however, it was found that upon detailed analysis, a large number, so categorized, were producing very well. A study also should be conducted on abandoned reservoirs. To utilize heavy oil, refiners will have to add various unit operations to their processes, such as hydrotreaters and hydrodesulfurizers and will require, in most cases, a lighter blending stock. A big problem in producing heavy oil is that of regulation; specifically, it was found that the regulatory constraints are so fluid and changing that one cannot settle on a favorable recovery and production plan with enough confidence in the regulatory requirements to commit capital to the project.

Possibilities for relativistic heavy ion collisions at Brookhaven  

SciTech Connect

Since 1980 there has been considerable interest at Brookhaven in exploiting the existence of the Colliding Beam Accelerator, CBA, earlier referred to as Isabelle, for the generation of heavy ion collisions at very high energies. The only requirement for a heavy ion collider would have been for an energy booster for the Tandem accelerator and a tunnel and magnet transport system to the AGS. For a few million dollars heavy ions up to nearly 200 GeV/amu could be collided with luminosities of 10/sup 27/ to 10/sup 28//cm/sup 2/ sec in experimental halls with ideal facilities for heavy ion physics studies. Although the CBA project has been stopped, it is still true that Brookhaven has in place enormous advantages for constructing a heavy ion collider. This paper describes a design that exploits those advantages. It uses the tunnel and other civil construction, the refrigerator, vacuum equipment, injection line components, and the magnet design for which there is expertise and a production facility in place. The result is a machine that appears quite different than would a machine designed from first principles without access to these resources but one which is of high performance and of very attractive cost.

Electron-State Hybridization in Heavy-Fermion Systems  

NLE Websites -- All DOE Office Websites (Extended Search)

Electron-State Hybridization in Heavy-Fermion Systems Print Electron-State Hybridization in Heavy-Fermion Systems Print Heavy-fermion systems are characterized by electrons with extremely large effective masses. The corresponding heavy-electron "quasiparticle" states are close to the Fermi energy and govern the thermodynamic, transport, and, in part, magnetic properties of these materials. In the case of rare-earth compounds, the quasiparticle states arise from the interactions (hybridization) of valence states with strongly localized 4f states. The question as to whether it is sufficient to treat the f states as localized impurities (single-impurity Anderson model) or whether the periodic crystal symmetry must be considered (periodic Anderson model) has been the subject of extensive debate. An international team of researchers from Germany, Ukraine, India, and the U.S. has performed angle-resolved photoemission spectroscopy (ARPES) studies of the heavy-fermion system YbIr2Si2. The results show a strong momentum (directional) dependence of the hybridization that clearly rules out the single-impurity model in favor of the lattice model.

Energy levels of a heavy ion moving in dense plasmas  

SciTech Connect

In this paper, the potential of a slowly moving test particle moving in collisional dense plasmas is studied. It is composed of the Debye-shielding potential, wake potential, and collision term. The Ritz variational-perturbational method is developed for calculating relativistic binding energy levels of a heavy ion moving in dense plasmas. Binding energy levels of a heavy ion moving in plasmas are calculated. The results show that both non-relativistic energy levels and relativistic energy levels become more negative as the temperature becomes high. They also become more negative as the number density decreasing. Relativistic correction is important for calculating binding energy levels. Both relativistic energy levels and non-relativistic energy levels vary minutely as the speed of heavy ion varies.

Heavy oil characterization method for PC-SAFT  

Science Journals Connector (OSTI)

Abstract Oil characterization is a crucial step in modeling heavy oil systems. Since heavy oil consists of thousands of components, for modeling purpose it is required to lump hydrocarbons into pseudocomponents. New generation equation of state (EoS), Perturbed-Chain Statistical Associating Fluid Theory (PC-SAFT), has shown promising results for modeling heavy oil systems. However, single carbon number type characterization approach has been lacking for PC-SAFT until now. The characterization method presented in this paper is based on sorting the pseudocomponents according to their boiling points. Further, each boiling point cut is split into saturate, aromatic and polyaromatic fractions. Asphaltenes are treated as a single pseudocomponent. For calculations, the PC-SAFT parameters were obtained for each pseudocomponent. The characterization procedure was validated by predicting densities for two heavy oils, three heavy oil cuts and propane + Athabasca bitumen (AB) and CO2 + propane + AB systems and comparing the results with measured data (109 data points). The relative average deviation was at its highest 2.1 % for density. In addition, saturation pressures were predicted for propane + AB and CO2 + propane + AB systems (57 data points). The saturation pressure predictions were as good as predicted earlier in the literature with Peng–Robinson EoS (in this work: the relative average deviations were 7.2 % and 2.0 % for propane + AB and CO2 + propane + AB systems). The calculations demonstrated that densities and gas solubilities for heavy oil systems can be accurately predicted with PC-SAFT without any adjustable PC-SAFT parameters if the distillation curve is available.

Friction coefficient for deep-inelastic heavy-ion collisions  

Science Journals Connector (OSTI)

Based on the microscopic model, the friction coefficient for the relative motion of nuclei in deep-inelastic heavy-ion collisions is calculated. An advantage of the suggested method is that it allows one to consider the relative motion of nuclei and the intrinsic motion self-consistently. The radial dependence of the friction coefficient is studied and the results are compared with those found by other methods. It was demonstrated that the kinetic energy dissipation in deep-inelastic heavy-ion collisions is a gradual process which takes up a significant part of a reaction time. A decrease of the radial friction coefficient with a heating of nuclei is shown.

Disentangling Effects of Nuclear Structure in Heavy Element Formation  

SciTech Connect

Forming the same heavy compound nucleus with different isotopes of the projectile and target elements allows nuclear structure effects in the entrance channel (resulting in static deformation) and in the dinuclear system to be disentangled. Using three isotopes of Ti and W, forming {sup 232}Cm, with measurement spanning the capture barrier energies, alignment of the heavy prolate deformed nucleus is shown to be the main reason for the broadening of the mass distribution of the quasifission fragments as the beam energy is reduced. The complex, consistently evolving mass-angle correlations that are observed carry more information than the integrated mass or angular distributions, and should severely test models of quasifission.

Compatibility of various approaches to heavy-quark fragmentation  

E-Print Network (OSTI)

We find that the definition of the heavy-quark fragmentation function given by Jaffe and Randall differs by a factor of the longitudinal-momentum fraction z from the standard Collins-Soper definition. Once this factor is taken into account, the explicit calculation of Braaten et al. is found to be in agreement with the general analysis of Jaffe and Randall. We also examine the model of Peterson et al. for heavy-quark fragmentation and find that the quoted values of the width and of the value of $z$ at the maximum are in error. The corrected values are in agreement with the analysis of Jaffe and Randall.

Energy loss for heavy quarks in relation to light partons; is radiative energy loss for heavy quarks anomalous?  

E-Print Network (OSTI)

The scaling properties of jet suppression measurements are compared for non-photonic electrons ($e^{\\pm}$) and neutral pions ($\\pi^0$) in Au + Au collisions at $\\sqrt{s_{NN}}=200$ GeV. For a broad range of transverse momenta and collision centralities, the comparison is consistent with jet quenching dominated by radiative energy loss for both heavy and light partons. Less quenching is indicated for heavy quarks via $e^{\\pm}$; this gives an independent estimate of the transport coefficient $\\hat{q}$ that agrees with its magnitude obtained from quenching of light partons via $\\pi^0$'s.

ENVIRONMENTAL IMPACT OF HEAVY METAL POLLUTION IN NATURAL AQUATIC SYSTEMS  

E-Print Network (OSTI)

He who taught the use of the pen, Taught man that which he knew not" The distribution of heavy metals between soil and soil solutions is a key issue in evaluating the environmental impact of long term applications of heavy metals to land. Contamination of soils by heavy metals has been reported by many workers. Metal adsorption is affected by many factors, including soil pH, clay mineralogy, abundance of oxides and organic matter, soil composition and solution ionic strength. The pH is one of the many factors affecting mobility of heavy metals in soils and it is likely to be the most easily managed and the most significant. To provide the appropriate level of protection for aquatic life and other uses of the resource, it is important to be able to predict the environmental distribution of important metals on spatial and temporal scales and to do so with particular emphasis on the water column concentrations. Regulatory levels reflected in water quality criteria or standards are based on

The effect of heavy metals on the activated sludge  

Science Journals Connector (OSTI)

The effect of heavy metal shock loading on biological treatment systems was studied by traditional methods and molecular biological techniques. Two kinds of SBR (sequence batch reactor) operation units, unacclimated and acclimated activated sludge systems, were studied. The addition of special nutrients and powdered activated carbon (PAC) to stimulate heavy metal uptake and recovery were studied. The kinetic constants could be used to describe the effect of the inhibition of substance utilisation. The results showed that heavy metal shock loading had a greater effect on the unacclimated activated sludge system than on the acclimated one. The special nutrients greatly enhanced the uptake of copper, and the PAC improved sludge settling and decreased the turbidity of the effluent. The variation of dominant species and the diversity of the bacterial community were analysed using 16S ribosomal DNA. Compared with the slight change of dominant species during acclimation by copper, there was a great change in the acclimated system shocked by a high concentration of copper. The results confirmed that the acclimation could improve the resistance of microorganisms to heavy metal toxicity.

Removal of heavy metals from samples of residual sludge  

Science Journals Connector (OSTI)

Nitric acid leaching processes were evaluated for removal of heavy metals from samples of residual sludge from an industrial and municipal wastewater plant. The study showed that an acid:water ratio of 1:1 and a nitric acid concentration of 2 mol 1?1 gave efficient removal of 86.7%, 100% and 100% of copper, nickel and arsenic.

Heavy Quark Production in Deep-Inelastic Scattering at HERA  

E-Print Network (OSTI)

We discuss two topics in the production of heavy quarks in deep-inelastic scattering: the next-to-leading order Monte-Carlo HVQDIS and the next-to-leading logarithmic resummation of soft gluon effects, including estimates of next-to-next-to-leading order corrections therefrom.

Inferring Magnetospheric Heavy Ion Density using EMIC Waves  

SciTech Connect

We present a method to infer heavy ion concentration ratios from EMIC wave observations that result from ionion hybrid (IIH) resonance. A key feature of the ion-ion hybrid resonance is the concentration of wave energy in a field-aligned resonant mode that exhibits linear polarization. This mode converted wave is localized at the location where the frequency of a compressional wave driver matches the IIH resonance condition, which depends sensitively on the heavy ion concentration. This dependence makes it possible to estimate the heavy ion concentration ratio. In this letter, we evaluate the absorption coefficients at the IIH resonance at Earth's geosynchronous orbit for variable concentrations of He+ and field-aligned wave numbers using a dipole magnetic field. Although wave absorption occurs for a wide range of heavy ion concentrations, it only occurs for a limited range of field-aligned wave numbers such that the IIH resonance frequency is close to, but not exactly the same as the crossover frequency. Using the wave absorption and observed EMIC waves from GOES-12 satellite, we demonstrate how this technique can be used to estimate that the He+ concentration is around 4% near L = 6.6.

Direct Measurements of the Lifetime of Heavy Hypernuclei  

E-Print Network (OSTI)

The lifetime of a Lambda particle embedded in a nucleus (hypernucleus) decreases from that of free Lambda decay due to the opening of the Lambda N to NN weak decay channel. However, it is generally believed that the lifetime of a hypernucleus attains a constant value (saturation) for medium to heavy hypernuclear masses, yet this hypothesis has been difficult to verify. The present paper reports a direct measurement of the lifetime of medium-heavy hypernuclei produced with a photon-beam from Fe, Cu, Ag, and Bi targets. The recoiling hypernuclei were detected by a fission fragment detector using low-pressure multi-wire proportional chambers. The experiment agrees remarkably well with the only previously-measured single-species heavy-hypernucleus lifetime, that of Fe56_Lambda at KEK, and has significantly higher precision. The experiment disagrees with the measured lifetime of an unknown combination of heavy hypernuclei with 180

Resonance Absorption and Regeneration in Relativistic Heavy Ion Collisions  

E-Print Network (OSTI)

The regeneration of hadronic resonances is discussed for heavy ion collisions at SPS and SIS-300 energies. The time evolutions of Delta, rho and phi resonances are investigated. Special emphasize is put on resonance regeneration after chemical freeze-out. The emission time spectra of experimentally detectable resonances are explored.
