One-Year Cloud Climatology for the One-Year Cloud Climatology for the Southern Great Plains Site T. P. Ackerman, R. T. Marchand, and E. E. Clothiaux Department of Meteorology The Pennsylvania State University University Park, Pennsylvania Introduction The addition of the millimeter wave cloud radar (MMCR) to the suite of instruments at the Southern Great Plains (SGP) site has provided the necessary observations to produce a cloud climatology. Data from the MMCR are currently being combined with data from the Belfort laser ceilometer (BLC) and micropulse lidar (MPL) to determine cloud occurrence and location using algorithms developed by our research group. These basic cloud statistics should prove useful for comparing with both single-column model (SCM) and general circulation model (GCM) predictions of cloud

Paradigm for Testing Cloud Parameterizations Paradigm for Testing Cloud Parameterizations T. P. Ackerman, M. Sengupta, and E. E. Clothiaux The Pennsylvania State University University Park, Pennsylvania Introduction One of the main goals of the Atmospheric Radiation Measurement (ARM) Program is improvement of cloud and radiation parameterizations in general circulation models. This problem can be logically addressed within a three-step framework: 1) prediction of clouds from thermodynamic fields, 2) parameterization of microphysical properties of the clouds, and 3) parameterization of radiative properties of the clouds. The information derived from the parameterizations is used in a radiative transfer scheme to calculate heating rates and surface fluxes. An important requirement for improving parameterizations is the availability of a continuous data

One of our goals in performing one-dimensional studies is to develop the microphysics for these three-dimensional simulations. However, since the microphysics itself is computationally very demanding, the one-dimensional simulations are often useful for cloud simulations of microphysics in situations in which dynamics either is not important or can be parameterized. Here we discuss only one-dimensional simulations. Marine stratus are the only clouds for which there are significant data showing effects of aerosols on cloud

Cirrus Radiative Properties in the Tropical Western Pacific Cirrus Radiative Properties in the Tropical Western Pacific J. M. Comstock and T. P. Ackerman Pacific Northwest National Laboratory Richland, Washington G. G. Mace University of Utah Salt Lake City, Utah Introduction Cirrus clouds in tropical regions are often located high in the cold upper troposphere and have low optical depths. In addition, tropical cirrus often extend in large sheets up to 1000 km horizontally, which may have a large influence on the energy budget of the atmosphere. Characterizing the location and radiative properties of cirrus clouds is an important step in understanding the processes that generate and maintain these cold, thin cirrus clouds and their impact on upper tropospheric dynamics. In this paper, we present cirrus radiative properties derived using a combination of Micropulse Lidar

SU?GG?J?14: Failure Mode and Effect Analysis (FMEA)?Based Quality Assurance for Dynamic MLC Tracking Systems  

Science Journals Connector (OSTI)

Purpose: Effective QA for newly introduced radiotherapy technology has received increased attention within the radiotherapy community and the general public. This work aims to develop and implement a FMEA?based quality management (QM) framework for dynamic MLC (DMLC) tumortracking systems.Methods: A systematic FMEA was performed for a prototype tumortracking system that uses the Calypso system for position monitoring and a DMLC for real?time beam adaptation. A process tree of DMLC tracking delivery was mapped and potential failure modes were identified. For each failure mode a risk probability number (RPN 1:1000) was calculated from the product of the probability of occurrence severity of effect and detectability of failure. Based on the insights obtained from FMEA commissioning and QA procedures were developed to check (i) coordinate transformation (ii) system latency (iii) delivery accuracy (iv) delivery efficiency and (v) system response to error conditions. Results: Failures modes with RPN ? 20 were: delivery accuracy efficiency and data communication integrity. These were recommended to be tested monthly. Failure modes with RPN FMEA proved to be a powerful and flexible tool to develop a QM framework for DMLC tracking. We conclude that the use of FMEA ensures efficient allocation of valuable clinical resources because the most critical failure modes receive the most attention. Finally consistent with the goals of FMEA this framework can serve as the basis of a dynamic QM program that is continuously updated with increasing intra? and inter?institutional experience.

SU?GG?I?110: Study of the Use of Protons and Carbon Ions for Patient Imaging  

Science Journals Connector (OSTI)

Purpose: An evaluation of protons and carbon?ions for generating radiographicimages is performed. The contrast signal?to?noise ratio energy and spatial spread of protons and carbon ions passing through various tissues defined in ICRU were evaluated for different incident energies. Method and Materials: The Monte Carlo package GEANT4 was used to simulate the transport of protons/carbon?ions through different ICRU soft tissues such as: H 2 O lung adipose tissue soft?tissue muscle cartilage and cortical bone. Proton energies were 150300 MeV and carbon ion energies were 360500 AMeV. In order to study how the energy and the spatial spread of the beam varies for different thicknesses of ICRU tissues. The incident proton and carbon ions were pencil beam like with spot size of 1 micron?meter and with direction of motion perpendicular to the surface of the phantom. The spatial spread of exit particles is obtained from the standard deviation of the position of the exit particles relative to the center of the incident beam.Results: The spatial?spread of 200300MeV protons and 360500 AMeV carbon?ions passing through 20cm of soft?tissue representing a typical body thickness was respectively 2mm and 0.05mm. Carbon?ions allow significantly better spatial resolution than protonbeams. The mean exit energy for protons and carbon?ions was respectively 87223MeV and 113320 AMeV. The energy spread of the protons and carbon?ions was respectively 5.18.0MeV and 1.280.91 AMeV. The contrast of 10mm of bone?to?soft tissue is 7.20%2.1% and 59%53% respectively for protons and carbon?ions. Conclusions The spatial?resolution attainable with protons and carbon?ions passing through 20cm is respectively 2mm and 0.050mm. The significantly heavier carbon ions suffer less multiple Coulomb scatter within the patient than the protons and therefore can allow sharper images.Contrast of bone?to?tissue is higher in carbon?ions than in protons. The high contrast makes this tool attractive for online treatment?position?verification.

SU?GG?T?509: Development of a Database and Software Tools for Outcome Analysis of Breast Cancer Radiotherapy  

Science Journals Connector (OSTI)

Purpose:Dose?volume response data for breast cancerradiotherapy (RT) are generally lacking. The purpose of this work is to develop a database and software tools to facilitate the analyses of short? and long?term radiationdose?volume responses of breast cancer RT. Method and Materials: As a part of the project aiming to develop the Research Analysis Platform and IGRTDatabases (RAPID) a database consisting of modules to enter breast cancer patient's demographic diagnosis and staging radiation treatment parameters dose?volume data and follow?up information was developed using FileMaker databasesoftware. Data is tabulated in Microsoft Excel and imported into RAPID. Treatment related toxicity definitions for the breast RT were incorporated into the database to standardize the documentation of toxicity which facilitates statistical and outcome analysis. Relevant data can be exported from the database for use with auxiliary software tools for dose?volume response analysis and outcome meta?analysis. RAPID will be integrated with other software tools such as CERR AutoEUD and DREES to facilitate modeling of dose?volume responses for treatment planning. Results: A database and software tools with capabilities of searching sorting any correlating input parameters are developed. Clinical data for breast cancer patients treated in our institution in the last 10 years with CT?based dosimetry planning are being entered into the database. A FileMaker server has been installed in our department to host RAPID and allows registered users to remotely access password?protected clinical data. Conclusions: A database and auxiliary tools as part of a software platform RAPID has been developed to facilitate storing clinical data and deriving dose?volume responses for breast cancer patients treated with radiation therapy.

SU?GG?J?167: Resonant X?Ray Irradiation of High?Z Nanoparticles for Cancer Theranostics  

Science Journals Connector (OSTI)

Purpose: Broadband X?ray sources employed in current cancer therapy are indiscriminant of tissue composition. We demonstrate significant dose enhancement by high?Z (HZ) sensitizing agents at resonant energies below the K?edge. This is of particular interest in cancer theranostics using agents such as goldnanoparticles embedded in malignant tissue.Method and Materials: Relativistic R?matrix calculations were performed for radiative transitions and photoionization for many HZ elements from Fe to U. Accurate cross section data and monochromatic attenuation coefficients were computed in energy ranges where the large k?a resonance complexes occur. Scaling laws up to HZ species such as Pt Au and U are studied. Depth dose curves based on photon transport in a numerical model containing muscle bone and tumor with 1mg/cc concentration of goldnanoparticles were calculated using the new resonant atomic data and compared with those calculated using standard evaluated data. Results: Giant resonance complexes were identified in all HZ species at energies below the respective K edge. For example the resonant attenuation coefficient for k?? transitions in Fe and Au are more than 1000 times higher than at their K edge. The average absorption efficiency in cm2/g of Au at ?68 keV is 7400 compared to 3.3 at the Au K?edge and only about 0.2 for C N O and 0.24 for Ca. The gold resonance complexes lie in the range 6780 keV below the K?edge. The calculations reveal preferential dose deposition ratio of 3 to 4 between the goldnanoparticle?bearingtumor and soft tissue (including surface) or bone. Conclusion: Opportunities exist to specifically target HZ?bearing tumors while sparing normal tissue at monochromatic or narrowband X?ray sources tuned to resonant energies. We identify and discuss potential sources for the generation of sufficiently intense K?alpha resonant radiation such as laser produced plasma devices and electron?beam ion traps.

SU?GG?J?138: Effect of RF Pulse Dwell Time on Eddy Current and Motion Compensation in Multi?Shot Diffusion?Weighted MRI  

Science Journals Connector (OSTI)

Purpose: Diffusion?weighted (DW) MRI can provide information to improve target delineation in radiation treatment planning. The widely used twice?refocused spin?echo (TRSE) sequence is optimized to diminish eddy current?induced geometric distortions. However the TRSE sequence imposes a longer minimum echo time which precludes its use in acquiring DW images in tissues with short T2s. We found that radiofrequency (RF) pulse dwell times can also affect DW image quality and demonstrate that high?fidelity multi?shot DW images can be obtained using the non?optimized Stejkal and Tanner (ST) sequence when short RF pulse dwell times are employed. Method and Materials: A pulse sequence of our own design was implemented to acquire DW images using ST and TRSE diffusion?encoding schemes with 25 usec and 2 usec RF pulse dwell times. Single? and multi?shot spiral DW images (b=0 1000 s/mm2) of phantom and healthy volunteer were acquired on a 3.0T Siemens Verio scanner.Images were reconstructed offline using custom software developed at our Institution. Results: Single? and multi?shot non?DW images did not exhibit a dependence on RF pulse dwell time. Furthermore single?shot DW images acquired with the TRSE method did not exhibit a dependence on RF pulse dwell time. However multi?shot DW images exhibited significant artifacts at long RF pulse dwell times even for the optimized TRSE method. Reducing the RF pulse dwell time improved the inherent immunity of the sequences to eddy current and motion?induced artifacts permitting acquisition of high?fidelity multi?shot DW images even with the non?optimized ST method. Conclusions: Compensation of eddy current and motion?induced artifacts in multi?shot DW imaging can be affected by choice of RF pulse dwell time. High?fidelity multi?shot DW images of short T2 tissues can be obtained using the non?optimized traditional ST method so long as the RF pulse dwell time is kept short.

Heavy metals in eggshells of cattle egret (Bubulcus ibis) and little egret (Egretta garzetta) from the Punjab province, Pakistan  

Science Journals Connector (OSTI)

Concentrations of nine trace metals were determined to assess site-specific and species-specific differences using Fast Sequential Atomic Absorption Spectrophotometer (Varian FAAS-240) in eggshells of Bubulcus ibis and Egretta garzetta from seven heronries in the Punjab province, Pakistan. Pattern of metal concentration followed the order: Fe>Zn>Pb>Mn>Cd>Cr>Li>Cu>Ni. Greater mean concentrations of Mn(1.17?g/g), Ni(0.11?g/g), Pb(1.49?g/g), Cd(0.88?g/g), Cr(0.7?g/g), Cu(0.20?g/g) and Li(0.27?g/g) were recorded in little egret. Mean concentrations of Mn, Pb, and Cr, (3.98, 5.4, 0.8?g/g) were significantly higher in eggshells collected from Shorkot; Cu, Zn and Ni (0.19, 13.0, 0.12?g/g) from the Trimu Headwork; Cd (1.23?g/g) from Jhang Faisalabad Road and Fe (67.98?g/g) from Mailsi. Multivariate analyses indicated that Mn, Pb, Cd, Ni, Cu, Cr and Zn were associated with anthropogenic activities and Fe and Li with natural origin. This study provides the baseline data for a monitoring program and revealed that egg-shells can serve as a bio-monitor of local metal contamination.

Speciation study of the heavy metals in commercially available recharge cards coatings in Nigeria and the health implication  

Science Journals Connector (OSTI)

Abstract This work assessed levels of heavy metals exposure from silver coatings of mobile phones recharge cards of three major companies (designated as A, B and C) with price denominations 100, 200 and 400 from companies A, B and C respectively, which were carefully scratched using a plastic scraper into a glass tube. The coatings were acid digested for total metal concentration, while speciation experiment for Mn, Cu, Cd and Pb was carried out. Total metals and speciation analysis were done using AAS and XRF techniques. The total metal concentration from XRF analysis was in the range: Ca (702140?g/g), K (204930?g/g), Sc (80270?g/g), Ti (153012,580?g/g), Fe (506660?g/g), Ni (202040?g/g), Cu (20850?g/g) and Zn (40460?g/g). Cr had the lowest concentration (10?g/g) in A ( 400) while Ti had the highest concentration (12,580?g/g) in C ( 500) for all the coatings analyzed. AAS and XRF results agreed closely except for Fe with higher concentration. A ( 100) contained high concentration of the metals compared with others. Speciation study identified Mn as the most mobile element when present in the environment.

A high-resolution and multi-year emissions inventory for biomass burning in Southeast Asia during 20012010  

Science Journals Connector (OSTI)

Abstract Biomass burning (BB) emissions from forest fires, agricultural waste burning, and peatland combustion contain large amounts of greenhouse gases (e.g., CO2, CH4, and N2O), which significantly impact ecosystem productivity, global atmospheric chemistry, and climate change. With the help of recently released satellite products, biomass density based on satellite and observation data, and spatiotemporal variable combustion factors, this study developed a new high-resolution and multi-year emissions inventory for BB in Southeast Asia (SEA) during 20012010. The 1-km grid was effective for quantifying emissions from small-sized fires that were frequently misinterpreted by coarse grid data due to their large smoothed pixels. The average annual BB emissions in SEA during 20012010 were 277Gg SO2, 1125Gg NOx, 55,388Gg CO, 3831Gg NMVOC, 553Gg NH3, 324Gg BC, 2406Gg OC, 3832Gg CH4, 817,809Gg CO2, and 99Gg N2O. Emissions were high in western Myanmar, Northern Thailand, eastern Cambodia, northern Laos, and South Sumatra and South Kalimantan of Indonesia. Emissions from forest burning were the dominant contributor to the total emissions among all land types. The spatial pattern of BB emissions was consistent with that of the burned areas. In addition, BB emissions exhibited similar temporal trends from 2001 to 2010, with strong interannual and intraannual variability. Interannual and intraannual emission peaks were seen during 2004, 2007, 2010, and JanuaryMarch and AugustOctober, respectively.

An angular-selective electron source for the KATRIN experiment  

E-Print Network [OSTI]

The KATRIN experiment is going to search for the average mass of the electron antineutrino with a sensitivity of 0.2 eV/c2. It uses a retardation spectrometer of MAC-E filter type to accurately measure the shape of the electron spectrum at the endpoint of tritium beta decay. In order to achieve the planned sensitivity the transmission properties of the spectrometer have to be understood with high precision for all initial conditions. For this purpose an electron source has been developed that emits single electrons at adjustable total energy and adjustable emission angle. The emission is pointlike and can be moved across the full flux tube that is imaged onto the detector. Here, we demonstrate that this novel type of electron source can be used to investigate the transmission properties of a MAC-E filter in detail.

Spin-on-doping for output power improvement of silicon nanowire array based thermoelectric power generators  

SciTech Connect (OSTI)

The output power of a silicon nanowire array (NWA)-bulk thermoelectric power generator (TEG) with Cu contacts is improved by spin-on-doping (SOD). The Si NWAs used in this work are fabricated via metal assisted chemical etching (MACE) of 0.010.02 ? cm resistivity n- and p-type bulk, converting ?4% of the bulk thickness into NWs. The MACE process is adapted to ensure crystalline NWs. Current-voltage and Seebeck voltage-temperature measurements show that while SOD mainly influences the contact resistance in bulk, it influences both contact resistance and power factor in NWA-bulk based TEGs. According to our experiments, using Si NWAs in combination with SOD increases the output power by an order of 3 under the same heating power due to an increased power factor, decreased thermal conductivity of the NWA and reduced Si-Cu contact resistance.

Microphysical and Optical Properties from Microphysical and Optical Properties from Multifilter Rotating Shadowband Radiometers E. Kassianov, J. Barnard, T. Ackerman, C. Flynn, and D. Flynn Pacific Northwest National Laboratory Richland, Washington Introduction Multifilter rotating shadowband radiometers (MFRSRs) provide measurements of the total and diffuse solar irradiances at six wavelengths (415, 500, 615, 673, 870 and 940 nm). Direct solar irradiances are inferred by finding the difference between the two measured irradiances, and the direct irradiances are used to derive spectral values of the aerosol optical depth (AOD; Harrison and Michalsky 1994; Alexandrov et al. 2002). Single-scattering albedos (SSAs) can be obtained from diffuse irradiances (Petters et al. 2003).

Shear Viscosity in a Gluon Gas  

Science Journals Connector (OSTI)

The relation of the shear viscosity coefficient to the recently introduced transport rate is derived within relativistic kinetic theory. We calculate the shear viscosity over entropy ratio ?/s for a gluon gas, which involves elastic gg?gg perturbative QCD (PQCD) scatterings as well as inelastic gg?ggg PQCD bremsstrahlung. For ?s=0.3 we find ?/s=0.13 and for ?s=0.6, ?/s=0.076. The small ?/s values, which suggest strongly coupled systems, are due to the gluon bremsstrahlung incorporated.

Synthesis, adsorption and regeneration of nanoporous silica aerogel and silica aerogel-activated carbon composites  

Science Journals Connector (OSTI)

Abstract Usage of aerogels as an adsorbent has become more widespread because of its specifications such as high porosity and specific surface. Nanometer silica aerogel and silica aerogel-activated carbon composites were synthesized using a water glass precursor by ambient pressure drying method. Then, the adsorption capacity of synthesized adsorbents was studied in terms of benzene and ethyl benzene adsorption by chromatography method for continuous and batch testing. Results showed that silica aerogel and silica aerogel-activated carbon composites had high tendency for benzene and ethyl benzene adsorption. Silica aerogel showed maximum adsorption capacity of 2.3gg?1 and 0.7gg?1 in static adsorption of benzene and ethyl benzene respectively. Also, in dynamic adsorption of benzene and ethyl benzene, silica aerogel had maximum equilibrium adsorption capacity of 0.954gg?1 and 0.219gg?1 respectively. Minimum equilibrium adsorption capacity in benzene and ethyl benzene static adsorption was related to activated carbon with 0.7gg?1 and silica aerogel2wt% activated carbon with 0.25gg?1 respectively. After adsorption process, silica aerogel and silica aerogel0.5wt% activated carbon composite were regenerated by solvent extractionthermal treatment method and, after at least 15 adsorption/desorption cycles, their adsorption capacity became fixed.

Stochastic Radiative Transfer in Broken Clouds: Stochastic Radiative Transfer in Broken Clouds: Validation Tests E. Kassianov, T. P. Ackerman, R. T. Marchand, and M. Ovtchinnikov Pacific Northwest National Laboratory Richland, Washington Introduction An approach for the stochastic description of the solar radiation transfer through broken fields with the arbitrary horizontal and vertical inhomogeneity have been introduced (Kassianov 2000). Different combinations of the random and maximum cloud overlap can be treated by the suggested approach. We derived the approximated equations for both the mean direct and diffuse solar radiance on the basis of the stochastic transfer equation and a new statistically inhomogeneous Makovian model of broken clouds. In this paper we estimate the accuracy and robustness of the approximated equations by using

However, spectral measurements of the transmission of solar infrared radiation through clear and cloudy skies with FTIR spectroscopy have indicated that still are certain clouds which absorb unexpectedly large amounts of near-infrared (NIR) radiation. The amounts are unexpected in the sense that radiation codes, including sophisticated algorithms such as MODTRAN4, do not model this strong NIR absorption effect. The absorption

Low Doses of Radiation on DNA Repair Low Doses of Radiation on DNA Repair Eric Ackerman Pacific Northwest National Laboratory Why this Project? Even low doses (0.1 Gy) exert measurable effects on DNA repair. The first-known oxidative lesion repaired only by nucleotide excision repair found in normal cells is cyclo-dA. This lesion is found in normal cells and thought to be a byproduct of oxidative metabolism. When this lesion occurs, it stimulates repair. If repair is stimulated by low dose radiation, there are some implications for human health. For example, do some individuals exhibit a greater, lower, or no stimulation to certain DNA lesions? If there are population polymorphism that influence DNA repair, then it would be possible to use our assay for screening individuals for repair sensitivity.

the Estimation of Clear-Sky Upwelling the Estimation of Clear-Sky Upwelling Shortwave and Longwave C.N. Long Pacific Northwest National Laboratory Richland, Washington Introduction Previous work (Long and Ackerman 2000; Long 2004) has concentrated on estimating the downwelling clear-sky irradiances and calculating the effect of clouds on the downwelling radiative energy budget. However, cloud forcing is defined for the difference between clear- and cloudy-sky net radiation, which includes the upwelling components. Thus, if we are to estimate the surface radiative cloud forcing, the means must be developed to estimate what the upwelling shortwave and longwave irradiance would be if the clouds were not present. Estimating the upwelling longwave (LW) is particularly troublesome in

Ackerman Cooperative Institute for Meteorological Satellite Studies University of Wisconsin - Madison Madison, Wisconsin Introduction Cloud-radiative processes in the Arctic have a large and significant effect on the global energy budget. Curry et al. (1996) have identified cloud phase as one of the primary unknowns, which affects the radiation budget in the Arctic. To correctly determine cloud properties, such as particle size and condensed water path that dictate the cloud's radiative effects, the cloud phase must be accurately determined. However, the presence of highly reflecting snow and ice, together with a persistent temperature inversion that exists much of the year, hampers the ability to remotely detect cloud phase.

Aerosols and the Residual Clear-Sky Aerosols and the Residual Clear-Sky Insolation Discrepancy T. P. Charlock National Aeronautics and Space Administration Langley Research Center Hampton, Virginia F. G. Rose and D. A. Rutan Analytical Services and Materials, Inc. Hampton, Virginia Abstract The "clear-sky insolation discrepancy" surfaced a few years ago: several well-regarded theoretical simulations (sound radiative transfer codes and carefully measured inputs for them) produced values for clear-sky shortwave (SW) insolation that exceeded measurements from 20 to 30 Wm -2 . Now, by both carefully screening (Long-Ackerman) the radiometer observations and including the record of the newly installed Eppley Black and White (B&W) pyranometer, we find theory exceeding observations by

Two measurement sites show statistically significant increases in clear- sky direct normal irradiance in background periods before and after the eruption of Mt. Pinatubo [6] (1987- 2008), consistent with the hypothesis that a reduction in anthropogenic aerosols may contribute to the increase in surface irradiance. References 1. Long, C.N. and T. P.

Wang Goddard Earth Sciences and Technology Center University of Maryland, Baltimore County College Park, Maryland K. Sassen Department of Meteorology University of Utah Salt Lake City, Utah Introduction Cirrus clouds affect the surface and top-of-atmosphere energy budgets strongly through albedo and greenhouse effects, and can produce large local variations in atmospheric heating with heating at cloud bottom and cooling at cloud top (Liou 1986; Webster and Stephens 1980). Starr and Cox (1985) found that radiative modulation of local buoyancy through horizontal structure affects the structure and bulk properties of cirrus. Ackerman et al.

Brightness Fields in Statistically Inhomogeneous Clouds Brightness Fields in Statistically Inhomogeneous Clouds E. I. Kassianov, T. P. Ackerman, R. T. Marchand, and M. Ovtchinnikov Pacific Northwest National Laboratory Richland, Washington Introduction The angular structure of reflected and transmitted radiation provides important information needed for remote sensing of a cloudy atmosphere. The model angular distributions of radiation can be obtained by direct numeric simulation of three-dimensional (3D) clouds and radiation (numerical averaging), and the equations for the mean radiance (analytical averaging). The advantage of numerical averaging is that the needed statistical parameters of a radiation field may be obtained for any cloud model with accuracy as high as necessary. This makes it possible to use this direct method to estimate the accuracy

Ackerman Environmental and Health Sciences Division Pacific Northwest National Laboratory Richland, Washington Introduction Radiative transfer and heating in the cloudy atmosphere depend on the specific three-dimensional (3D) structure of the cloud field in question. However, detailed 3D cloud field measurements are rare. As a result, studies of 3D radiative transfer through clouds have frequently assumed that the spatial characteristics of cloud fields are isotropic in the horizontal dimensions.

Marchand Pacific Northwest National Laboratory Richland, Washington Introduction Satellite remote sensing is the major source for statistics of cloud properties; however, accurate and robust methods for extracting both optical and geometrical characteristics of broken clouds have yet to be fully developed. Currently, most broken cloud retrieval schemes rely on spectral (e.g., microwave, visible, or infrared [IR]) observations from near-vertically pointing remote sensors (Rossow 1989; Minnis et al. 1992). Although the multi-spectral techniques can provide accurate retrievals of cloud

Effect of Stratus on Solar Radiation: A Study Using Effect of Stratus on Solar Radiation: A Study Using Millimeter Wave Cloud Radar and Microwave Radiometer Data From the Southern Great Plains M. Sengupta and T. P. Ackerman Pacific Northwest National Laboratory Richland, Washington E. E. Clothiaux The Pennsylvania State University University Park, Pennsylvania Introduction Clouds are important players in the global radiation budget with low-level water clouds being one of the most influential types. Classified as stratocumulus and stratus, these water clouds cover 34% of oceans and 18% of land at any given time (Considine et al. 1997). A 50% plus global coverage, a high albedo when compared to the ocean, and temperatures comparable to the surface causes the low stratiform clouds to provide about 60% of the annually averaged net cloud radiative forcing (Hartmann et al.

Ackerman Department of Meteorology Pennsylvania State University University Park, Pennsylvania The effect of clouds on the shortwave (SW) irradiance near the surface is of interest for surface radiative energy budget studies (Long et al. 1994) and investigation of the recently suggested excess SW cloud absorption (Cess et al. 1995; Ramanathan et al. 1995; Pilewski and Valero 1995).

Ackerman Pacific Northwest National Laboratory Richland, Washington Introduction The state variables of the atmosphere exhibit correlations at various spatial and temporal scales. These correlations are crucial for understanding short- and long-term trends in climate. Cirrus clouds are important phenomena in the troposphere affecting climate. To improve future parameterization of cirrus clouds in climate models, we must understand the cloud properties and how they change within the cloud. We consider fluctuations of cloud radar signals obtained at isodepths within cirrus clouds

NOAA operational OLR estimation is based on flux equivalent temperature defined by the narrow band TBB. We found the relationship between ERBE OLR and brightness temperature (TBB) was different depending on cloud type classified by the split window. The brightness temperature difference between the split window (BTD) is a good indicator of water vapor amount and cloud optical properties. Therefore, we use the TBB and BTD to determine the regression

Comparisons of model output and observational data generally require averaging (or aggregating) the observations in an attempt to put them on the same large spatial scale as

Tropical Radiative Heating Profiles in the Multi- Tropical Radiative Heating Profiles in the Multi- Scale Modeling Framework: A Comparison to Atmospheric Radiation Measurement Program Observations S.A. McFarlane, J.H. Mather, and T.P. Ackerman Pacific Northwest National Laboratory Richland, Washington Introduction Radiative heating associated with the distribution of water vapor and clouds in the atmosphere is an important driver of both local-scale and large-scale circulations in the tropics. One of the difficulties in producing accurate cloud and radiative heating rate profiles with a general circulation model (GCM) is the sub-grid scale nature of cloud processes and their interaction with radiation. The multi-scale modeling framework (MMF) is a new approach to climate modeling (Grabowski 2001; Khairoutdinov

Evaluation of MWR Retrievals Evaluation of MWR Retrievals of Liquid Water Path and Precipitable Water Vapor R. T. Marchand and T. P. Ackerman Pacific Northwest National Laboratory Richland, Washington Introduction This paper offers some observations on the quality of Microwave Radiometer (MWR) retrievals of precipitable water vapor (PWV) and liquid water path (LWP). The paper shows case study comparisons between the standard "statistical" approach and those obtained using an iterative solution of the microwave radiative transfer equations. These examples show how improvements in the retrieval of LWP can be obtained by using an iterative approach, but that possible improvements are limited by the accuracy of the forward model absorption coefficients and errors in the brightness temperature measurements. Each of these effects limits the

Bayes' theorem relates the inverse problem (retrieving cloud properties from remote- sensing observations) to the forward problem (modeling remote-sensing observations given a set of cloud properties). It also formally includes prior information about cloud microphysics, with this information explicitly modeled by a probability distribution function in the parameter space, not hidden

Currently only 1/10th attomole =105 damaged molecules/cell and 3000 cells/measurement are required. We have found that even low doses (10 rad) exert measurable effects on DNA repair. Interestingly, the amount of DNA repair increases at 10-50 rads, plateaus, and then increases even further at higher doses well below doses where radiation-induced lethality

Artocarpus heterophyllus L. seed starch-blended gellan gum mucoadhesive beads of metformin \\{HCl\\}  

Science Journals Connector (OSTI)

Abstract Jackfruit (Artocarpus heterophyllus Lam., family: Moraceae) seed starch (JFSS)gellan gum (GG) mucoadhesive beads containing metformin \\{HCl\\} were developed through ionotropic gelation technique. The effect of GG to JFSS ratio and CaCl2 concentration on the drug encapsulation efficiency (DEE, %) and cumulative drug release at 10h (R10h, %) was optimized and analyzed using response surface methodology based on 32 factorial design. The optimized JFSSGG beads containing metformin \\{HCl\\} showed DEE of 92.674.46%, \\{R10h\\} of 61.302.37%, and mean diameter of 1.670.27mm. The optimized beads showed pH-dependent swelling and mucoadhesivity with the goat intestinal mucosa. The in vitro drug release from all these JFSSGG beads containing metformin \\{HCl\\} was followed zero-order pattern (R2=0.99070.9975) with super case-II transport mechanism over a period of 10h. The beads were also characterized by SEM and FTIR. The optimized JFSSGG beads containing metformin \\{HCl\\} exhibited significant hypoglycemic effect in alloxan-induced diabetic rats over prolonged period after oral administration.

OECD MCCI project long-term 2-D molten core concrete interaction test design report, Rev. 0. September 30, 2002.  

SciTech Connect (OSTI)

The Melt Attack and Coolability Experiments (MACE) program at Argonne National Laboratory addressed the issue of the ability of water to cool and thermally stabilize a molten core-concrete interaction when the reactants are flooded from above. These tests provided data regarding the nature of corium interactions with concrete, the heat transfer rates from the melt to the overlying water pool, and the role of noncondensable gases in the mixing processes that contribute to melt quenching. As a follow-on program to MACE, The Melt Coolability and Concrete Interaction Experiments (MCCI) project is conducting reactor material experiments and associated analysis to achieve the following two technical objectives: (1) resolve the ex-vessel debris coolability issue through a program that focuses on providing both confirmatory evidence and test data for the coolability mechanisms identified in MACE integral effects tests, and (2) address remaining uncertainties related to long-term two-dimensional molten core-concrete interactions under both wet and dry cavity conditions. Achievement of these two objectives will demonstrate the efficacy of severe accident management guidelines for existing plants, and provide the technical basis for better containment designs for future plants. In terms of the first program objective, the Small-Scale Water Ingression and Crust Strength (SSWICS) test series has been initiated to provide fundamental information on the ability of water to ingress into cracks and fissures that form in the debris during quench, thereby augmenting the otherwise conduction-limited heat transfer process. A test plan for Melt Eruption Separate Effects Tests (MESET) has also been developed to provide information on the extent of crust growth and melt eruptions as a function of gas sparging rate under well-controlled experiment conditions. In terms of the second program objective, the project Management Board (MB) has approved startup activities required to carry out experiments to address remaining uncertainties related to long-term two-dimensional molten core-concrete interaction. In particular, for both wet and dry cavity conditions, there is uncertainty insofar as evaluating the lateral vs. axial power split during a core-concrete interaction due to a lack of experiment data. As a result, there are differences in the 2-D cavity erosion predicted by codes such as MELCOR, WECHSL, and COSACO. The first step towards generating this data is to produce a test plan for review by the Project Review Group (PRG). The purpose of this document is to provide this plan.

These tests provided data regarding the nature of corium interactions with concrete, the heat transfer rates from the melt to the overlying water pool, and the role of noncondensable gases in the mixing processes that contribute to melt quenching.

Achievement of these two program objectives will demonstrate the efficacy of severe accident management guidelines for existing plants, and provide the technical basis for better containment designs for future plants. In terms of satisfying these objectives, the Management Board (MB) approved the conduct of two long-term 2-D Core-Concrete Interaction (CCI) experiments designed to provide information in several areas, including: (i) lateral vs. axial power split during dry core-concrete interaction, (ii) integral debris coolability data following late phase flooding, and (iii) data regarding the nature and extent of the cooling transient following breach of the crust formed at the melt-water interface. This data report provides thermal hydraulic test results from the CCI-1 experiment, which was conducted on December 19, 2003. Test specifications for CCI-1 are provided in Table 1-1. This experiment investigated the interaction of a fully oxidized 400 kg PWR core melt, initially containing 8 wt % calcined siliceous concrete, with a specially designed two-dimensional siliceous concrete test section with an initial cross-sectional area of 50 cm x 50 cm. The report begins by providing a summary description of the CCI-1 test apparatus and operating procedures, followed by presentation of the thermal-hydraulic results. The posttest debris examination results will be provided in a subsequent publication. Observations drawn within this report regarding the overall cavity erosion behavior may be subject to revision once the posttest examinations are completed, since these examinations will fully reveal the final cavity shape.

A Novel Statistical Channel Model for Turbulence-Induced Fading in Free-Space Optical Systems  

E-Print Network [OSTI]

In this paper, we propose a new probability distribution function which accurately describes turbulence-induced fading under a wide range of turbulence conditions. The proposed model, termed Double Generalized Gamma (Double GG), is based on a doubly stochastic theory of scintillation and developed via the product of two Generalized Gamma (GG) distributions. The proposed Double GG distribution generalizes many existing turbulence channel models and provides an excellent fit to the published plane and spherical waves simulation data. Using this new statistical channel model, we derive closed form expressions for the outage probability and the average bit error as well as corresponding asymptotic expressions of free-space optical communication systems over turbulence channels. We demonstrate that our derived expressions cover many existing results in the literature earlier reported for Gamma-Gamma, Double-Weibull and K channels as special cases.

Cirrus Horizontal Inhomogeneity and OLR Bias Cirrus Horizontal Inhomogeneity and OLR Bias Q. Fu and B. Carlin Department of Oceanography Dalhousie University Halifax, Nova Scotia Canada G. G. Mace Department of Meteorology University of Utah Salt Lake City, Utah Introduction Clouds exhibit dramatic variabilities at spatial scales smaller than typical grid cells of large-scale models used to study climate and weather. These unresolved cloud fluctuations are potentially important for parameterizations of both cloud radiative effects and cloud microphysical processes (e.g., Harshvardhan and Randall 1985; Jacob and Kein 1999). It is now well accepted that neglect of cloud subscale variability can seriously bias model estimates of the disposition of solar radiation in the earth- atmosphere system (e.g., Cahalan et al. 1994a; Barker 1996).

Li Earth System Science Interdisciplinary Center University of Maryland College Park, Maryland Z. Li Department of Meteorology University of Maryland College Park, Maryland Introduction Cirrus clouds can largely modify the solar reflected and terrestrial emitted radiances. The ubiquitous presence of cirrus clouds has a global coverage of about 20% to30% and more than 70% in the tropics (Wylie et al. 1994). The probability of cirrus clouds overlaying a low-level boundary layer cloud system is greater than 50% (Hahn et al. 1982, 1984; Tian and Curry 1989; Mace et al. 1997). They are often optically thin and semitransparent and frequently reside in high altitude overlapping with a low-level

We are developing an innovative algorithm to simultaneously retrieve cirrus microphysical parameters and air mean vertical motion by using the three moments of the Doppler spectrum. The technique utilizes a statement that the observed Doppler spectrum is the convolution of a quiet air reflectivity spectrum with the turbulence PDF (probability density function).

OECD/MCCI 2-D Core Concrete Interaction (CCI) tests : final report February 28, 2006.  

SciTech Connect (OSTI)

Although extensive research has been conducted over the last several years in the areas of Core-Concrete Interaction (CCI) and debris coolability, two important issues warrant further investigation. The first issue concerns the effectiveness of water in terminating a CCI by flooding the interacting masses from above, thereby quenching the molten core debris and rendering it permanently coolable. This safety issue was investigated in the EPRI-sponsored Melt Attack and Coolability Experiments (MACE) program. The approach was to conduct large scale, integral-type reactor materials experiments with core melt masses ranging up to two metric tons. These experiments provided unique, and for the most part repeatable, indications of heat transfer mechanism(s) that could provide long term debris cooling. However, the results did not demonstrate definitively that a melt would always be completely quenched. This was due to the fact that the crust anchored to the test section sidewalls in every test, which led to melt/crust separation, even at the largest test section lateral span of 1.20 m. This decoupling is not expected for a typical reactor cavity, which has a span of 5-6 m. Even though the crust may mechanically bond to the reactor cavity walls, the weight of the coolant and the crust itself is expected to periodically fracture the crust and restore contact with the melt. Although crust fracturing does not ensure that coolability will be achieved, it nonetheless provides a pathway for water to recontact the underlying melt, thereby allowing other debris cooling mechanisms to proceed. A related task of the current program, which is not addressed in this particular report, is to measure crust strength to check the hypothesis that a corium crust would not be strong enough to sustain melt/crust separation in a plant accident. The second important issue concerns long-term, two-dimensional concrete ablation by a prototypic core oxide melt. As discussed by Foit the existing reactor material database for dry cavity conditions is solely one-dimensional. Although the MACE Scoping Test was carried out with a two-dimensional concrete cavity, the interaction was flooded soon after ablation was initiated to investigate debris coolability. Moreover, due to the scoping nature of this test, the apparatus was minimally instrumented and therefore the results are of limited value from the code validation viewpoint. Aside from the MACE program, the COTELS test series also investigated 2-D CCI under flooded cavity conditions. However, the input power density for these tests was quite high relative to the prototypic case. Finally, the BETA test series provided valuable data on 2-D core concrete interaction under dry cavity conditions, but these tests focused on investigating the interaction of the metallic (steel) phase with concrete. Due to these limitations, there is significant uncertainty in the partition of energy dissipated for the ablation of concrete in the lateral and axial directions under dry cavity conditions for the case of a core oxide melt. Accurate knowledge of this 'power split' is important in the evaluation of the consequences of an ex-vessel severe accident; e.g., lateral erosion can undermine containment structures, while axial erosion can penetrate the basemat, leading to ground contamination and/or possible containment bypass. As a result of this uncertainty, there are still substantial differences among computer codes in the prediction of 2-D cavity erosion behavior under both wet and dry cavity conditions. In light of the above issues, the OECD-sponsored Melt Coolability and Concrete Interaction (MCCI) program was initiated at Argonne National Laboratory. The project conducted reactor materials experiments and associated analysis to achieve the following technical objectives: (1) resolve the ex-vessel debris coolability issue through a program that focused on providing both confirmatory evidence and test data for the coolability mechanisms identified in MACE integral effects tests, and (2) address remaining uncertainties relat

Measurement of the fraction of tt production via gluon-gluon fusion in pp collisions at {radical}(s)=1.96 TeV  

SciTech Connect (OSTI)

We present a measurement of the ratio of the tt production cross section via gluon-gluon fusion to the total tt production cross section in pp collisions at {radical}(s)=1.96 TeV at the Tevatron. Using a data sample with an integrated luminosity of 955 pb{sup -1} recorded by the CDF II detector at Fermilab, we select events based on the tt decay to lepton+jets. Using an artificial neural network technique we discriminate between tt events produced via qq annihilation and gg fusion, and find G{sub f}={sigma}(gg{yields}tt)/{sigma}(pp{yields}tt)<0.33 at the 68% confidence level. This result is combined with a previous measurement to obtain the most stringent measurement of this quantity by CDF to date, G{sub f}=0.07{sub -0.07}{sup +0.15}.

Decadal growth of black carbon emissions in India - article no. L02807  

SciTech Connect (OSTI)

A Geographical Information System (GIS) based methodology has been used to construct the black carbon (BC) emission inventory for the Indian geographical region. The distribution of emissions from a broader level to a spatial resolution of 1{sup o} x 1{sup o} grid has been carried out by considering micro level details and activity data of fossil fuels and bio-fuels. Our calculated total BC emissions were 1343.78 Gg and 835.50 Gg for the base years 2001 and 1991 respectively with a decadal growth of around 61%, which is highly significant. The district level analysis shows a diverse spatial distribution with the top 10% emitting districts contributing nearly 50% of total BC emission. Coal contributes more than 50% of total BC emission. All the metropolitan cities show high BC emissions due to high population density giving rise to high vehicular emissions and more demand of energy.

From realistic 2HDM-II CPV benchmarks to the $H^\\pm \\to\\tau \  

E-Print Network [OSTI]

Phenomenological studies of a CP-violating two-Higgs-doublet Model with type-II Yukawa couplings are presented. In the light of recent LHC data, an update on the viable parameter space that survives both the experimental and theoretical constraints is provided. In addition, the scope of the LHC in exploring this model through the discovery of a charged Higgs boson that decays in the tauonic mode is analysed. For this, various production channels were investigated, with emphasis on the boson-associated channel $gg\\to H_i\\to H^\\pm W^\\mp$ and the fermion-associated channels $gb\\to H^\\pm t$ and $gg\\to H^\\pm bt$. For the latter, a signal-over-background analysis is performed.

The stationary phase point method for transitional scattering: diffractive radio scintillation for pulsar  

E-Print Network [OSTI]

The stationary phase point (SPP) method in one-dimensional case is introduced to treat the diffractive scintillation. From weak scattering, where the SPP number N=1, to strong scattering (N$\\gg$1), via transitional scattering regime (N$\\sim$2,3), we find that the modulation index of intensity experiences the monotonically increasing from 0 to 1 with the scattering strength, characterized by the ratio of Fresnel scale $\\rf$ to diffractive scale $\\rdiff$.

Phenomenology of turbulent dynamo growth and saturation  

E-Print Network [OSTI]

With a non local shell model of magnetohydrodynamic turbulence we investigate numerically the turbulent dynamo action for low and high magnetic Prandtl numbers ($Pm$). The results obtained in the kinematic regime and along the way to dynamo saturation are understood in terms of a phenomenological approach based on the local ($Pm\\ll 1$) or non local ($Pm\\gg 1$) nature of the energy transfers. In both cases the magnetic energy grows at small scale and saturates as an inverse `` cascade ''.

Evaluation of Preindustrial to Present-day Black Carbon and its Albedo Forcing from Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP)  

SciTech Connect (OSTI)

As a part of the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP), we evaluate the historical black carbon (BC) aerosols simulated by 8 ACCMIP models against the observations including 12 ice core records, a long-term surface mass concentrations and recent Arctic BC snowpack measurements. We also estimate BC albedo forcing by performing additional simulations using the NCAR Community Land and Sea-Ice model 4 with prescribed meteorology from 1996-2000, which includes the SNICAR BC-snow model. We evaluated the vertical profile of BC snow concentrations from these offline simulations to using recent BC snowpack measurements. Despite using the same BC emissions, global BC burden differs by approximately a factor of 3 among models due to the differences in aerosol removal parameterizations and simulated meteorology among models; 34 Gg to 103 Gg in 1850 and 82 Gg to 315 Gg in 2000. However,models agree well on 2.5~3 times increase in the global BC burden from preindustrial to present-day, which matches with the 2.5 times increase in BC emissions. We find a large model diversity at both NH and SH high latitude regions for BC burden and at SH high latitude regions for deposition fluxes. The ACCMIP simulations match the observed BC mass concentrations well in Europe and North America except at Jungfrauch and Ispra. However, the models fail to capture the Arctic BC seasonality due tosevere underestimations during winter and spring. Compared to recent snowpack measurements, the simulated vertically resolved BC snow concentrations are, on average, within a factor of 2-3 of observations except for Greenland and Arctic Ocean. However, model and observation differ widely due to missing interannual variations in emissions and possibly due to the choice of the prescribed meteorology period (i.e., 1996-2000).

Light sfermion interplay in the 125 GeV MSSM Higgs production and decay at the LHC  

E-Print Network [OSTI]

We study the effects from light sfermions on the lightest Higgs boson production and decay at the Large Hadron Collider (LHC) within the Minimal Supersymmetric Standard Model (MSSM). We find that the scenario with light coloured sfermions -- stops or sbottoms -- has the potential to explain a non-universal alteration, as hinted by LHC data, of the gluon-gluon Fusion ($\\mu_{ggF}$) with respect to the Vector Boson Fusion ($\\mu_{VBF}$) event rates and, in particular, can predict $\\frac{\\mu_{VBF}}{\\mu_{ggF}}>1$ for all Higgs boson decay channels in large areas of the parameter space. We also find that the scenario with a light stop/sbottom can be complemented by the scenario in which the total Higgs width, $\\Gamma_{\\rm tot}$, is reduced due to a suppressed Yukawa coupling $Y_b$. In this case, the reduction of the Higgs production rates in the $ggF$ process which occurs in the maximal mixing scenario is compensated by the reduction of the $H\\to b\\bar{b}$ partial decay width, the largest component of $\\Gamma_{\\rm t...

Emission factor estimates of cereal waste burning in Spain  

Science Journals Connector (OSTI)

Every year more than 5 million ha of cereal fields are affected by fires in order to eliminate cereal waste in Spain. The characteristics of this type of fire with intense flames are similar to those of the African dry savanna heading fires. This paper surveys the atmospheric emission caused by this process by combining results of field and combustion chamber experiments. Combustion chamber experiments show that during the flaming phase 88% of the fire exposed carbon is converted into CO2 and during the smoldering phase this percentage changes to 74%. These combustion chamber experiments also show that the soluble part of the aerosols emitted during the course of fires only represent 3% of the total particulate matter (TPM) produced, being the ions K+ and CI? the predominant ones. The cereal waste fire process can be represented by an arithmetic combination that takes into account the amounts of mass burned during the two phases of the fire: 0.90 flaming +0.10 smoldering. Emission factor estimates from field burning experiment are 137g TPMkg?1(dm) and 2.80.2g NOxkg?1 (dm). Finally, we obtain average emissions of 80130Gg TPM, 1728Gg NOx, 210350Gg CO and 814Tg CO2 in Spain. These emissions represent nearly 25% of the total \\{NOx\\} and 50% of the total CO2 emissions by other pollution sources during the burning period in Spain.

Pollution by cereal waste burning in Spain  

Science Journals Connector (OSTI)

In this paper, the amount of cereal waste burned in Spain, which represents the most important source of biomass burning in this country, is estimated. During the period between 1980 and 1998, an average mass of 8 Tg of cereal waste was burned annually, with remaining 1 Tg of ash on the cereal fields after combustion. By using emission factors previously calculated by Ortiz de Zrate et al. [Ortiz de Zrate, I., Ezcurra, A., Lacaux, J.P., Van Dihn, P., 2000. Emission factor estimates of cereal waste burning in Spain. Atmos. Environ. 34, 31833193.], it is deduced that pollutant emissions linked to cereal waste-burning process reach values of 11 Tg CO2, 80 Gg of TPM and 23 Gg of \\{NOx\\} year?1 during the cereal-burning period. These emissions represent 46% of total CO2 and 23% \\{NOx\\} emitted in Spain during the burning period that lasts 1 month after harvesting. Therefore, the relative importance of cereal waste burning as pollutant source in Spain almost during fire period becomes evident. Finally, our study allows to deduce that the production of 1 kg of cereal crop implies that 410 g of carbon and 3.3 g of nitrogen are going to be introduced into the atmosphere by this pollutant process. We estimate a total gaseous emission of 3.3 Tg of C and 25 Gg N as different pollutants by cereal waste burning.

Informal Preliminary Report on Comparisons of Prototype SPN-1 Radiometer to PARSL Measurements  

SciTech Connect (OSTI)

The prototype SPN-1 has been taking measurements for several months collocated with our PNNL Atmospheric Remote Sensing Laboratory (PARSL) solar tracker mounted instruments at the Pacific Northwest National Laboratory (PNNL) located in Richland, Washington, USA. The PARSL radiometers used in the following comparisons consist of an Eppley Normal Incident Pyrheliometer (NIP) and a shaded Eppley model 8-48 Black and White pyrgeometer (B&W) to measure the direct and diffuse shortwave irradiance (SW), respectively. These instruments were calibrated in mid-September by comparison to an absolute cavity radiometer directly traceable to the world standard group in Davos, Switzerland. The NIP calibration was determined by direct comparison, while the B&W was calibrated using the shade/unshade technique. All PARSL data prior to mid-September have been reprocessed using the new calibration factors. The PARSL data are logged as 1-minute averages from 1-second samples. Data used in this report span the time period from June 22 through December 1, 2006. All data have been processed through the QCRad code (Long and Shi, 2006), which itself is a more elaborately developed methodology along the lines of that applied by the Baseline Surface Radiation Network (BSRN) Archive (Long and Dutton, 2004), for quality control. The SPN-1 data are the standard total and diffuse SW values obtained from the analog data port of the instrument. The comparisons use only times when both the PARSL and SPN-1 data passed all QC testing. The data were further processed and analyzed by application of the SW Flux Analysis methodology (Long and Ackerman, 2000; Long and Gaustad, 2004, Long et al., 2006) to detect periods of clear skies, calculate continuous estimates of clear-sky SW irradiance and the effect of clouds on the downwelling SW, and estimate fractional sky cover.

Structural investigations of platinum anticancer drugs with DNA  

SciTech Connect (OSTI)

The antitumor agent cis-diamminedichloroplatinum (II) (cis-DDP) can successfully treat testicular and ovarian cancers, presumably by binding to DNA and preventing replication. cis-DDP is less successful in treating lung and breast cancers and the trans isomer is inactive. It has been suggested that cellular recognition and repair processes may be responsible for the difference in activity between cis- and trans-DDP, the differential effectiveness against different types of cancers, as well as acquired resistance. The author reviews structural methods used to characterize several site-specific adducts. Structure-function relations that emerge may help clarify the mechanism of action. The extent of DNA bending caused by several site-specific DNA adducts formed by cis- and trans-DDP has been determined using a gel electrophoresis assay. The adducts cis-GG, cis-AG, cis-GTG, and trans-GTG were incorporated into synthetic DNA oligonucleotides of varying lengths with two bp cohesive ends. Subtle DNA distortions were amplified by polymerizing these monomers and quantitated using polyacrylamide gel electrophoresis. The three adducts cis-GG, cis-AG, and cis-GTG were all found to bend the helix in a directed fashion by about 32-35[degrees]. The trans-GTG adduct gave a degree of flexibility to the double helix, allowing bending in more than one direction. The DNA unwinding caused by the platinum binding was measured by systematically varying the interplatinum distance in a series of synthetic DNA oligonucleotides. The cis-GG and cis-AG adducts both unwind the double helix by 13[degrees]C, while the cis-GTG adduct unwinds by 23[degrees]. To determine the complete structure of platinated duplex DNA< single crystals of a platinated 12 base pair duplex oligonucletide were obtained. Despite extreme temperature and radiation sensitivity problems, a complete set of data was collected. Several different approaches to solve the structure were attempted.

Electromagnetically induced transparency and dark fluorescence in a cascade three-level diatomic lithium system  

Science Journals Connector (OSTI)

Following our previous brief report [Phys. Rev. Lett. 88, 173003 (2002)], we report here a detailed study of electromagnetically induced transparency (EIT) and dark fluorescence in a cascade three-level diatomic lithium system using optical-optical double resonance (OODR) spectroscopy for both resonance and off resonance coupling. When a strong coupling laser couples the intermediate state A?u+1(v=13,J=14) to the upper state G?g1(v=11,J=14) of Li27, the fluorescence from both A?u+1 and G?g1 states was drastically reduced as the weak probe laser was tuned through the resonance transition between the ground state X?g+1(v=4,J=15) and the excited state A?u+1(v=13,J=14). The strong coupling laser makes an optically thick medium transparent for the probe transition. In addition, the fact that fluorescence from the upper state G?g1(v=11,J=14) was also dark when both lasers were tuned at resonance implies that the molecules were trapped in the ground state. We used density matrix methods to simulate the response of an open molecular three-level system to the action of a strong coupling field and a weak probe field. The analytical solutions were obtained under the steady-state condition. We have incorporated the magnetic sublevel (M) degeneracy of the rotational levels in the line shape analysis and report ?M? dependent line shape splitting. Our theoretical calculations are in excellent agreement with the observed fluorescence spectra. We show that the coherence is remarkably preserved even when the coupling field was detuned far from the resonance.

Two Dimensional Renormalization Group Flows in Next to Leading Order  

E-Print Network [OSTI]

Zamolodchikov's famous analysis of the RG trajectory connecting successive minimal CFT models $M_p$ and $M_{p-1}$ for $p\\gg 1$, is improved by including second order in coupling constant corrections. This allows to compute IR quantities with next to leading order accuracy of the $1/p$ expansion. We compute in particular, the beta function and the anomalous dimensions for certain classes of fields. As a result we are able to identify with a greater accuracy the IR limit of these fields with certain linear combination of the IR theory $M_{p-1}$. We discuss the relation of these results with Gaotto's recent RG domain wall proposal.

Automating dipole subtraction  

E-Print Network [OSTI]

We report on automating the Catani-Seymour dipole subtraction which is a general procedure to treat infrared divergences in real emission processes at next-to-leading order in QCD. The automatization rests on three essential steps: the creation of the dipole terms, the calculation of the color linked squared Born matrix elements, and the evaluation of different helicity amplitudes. The routines have been tested for a number of complex processes, such as the real emission process gg --> t anti-t ggg.

The hierarchy $\\Delta m^2_{atm} \\gg \\Delta m^2_\\odot$ and the large $\\theta_{23}$ mixing angle, as suggested by neutrino oscillation experiments, can be accounted for by a variety of lepton flavour models. A dichotomy emerges: i) Models were all neutrino masses are bounded by $m_{atm}\\equiv (\\Delta m^2_{atm})^{1/2}\\approx 0.03 eV$; ii) Models of quasi-degenerate neutrinos. It is shown how these different patterns of neutrino masses may arise from different lepton flavour symmetries. Physical implications are discussed in the various cases.

A SEARCH FOR L/T TRANSITION DWARFS WITH Pan-STARRS1 AND WISE: DISCOVERY OF SEVEN NEARBY OBJECTS INCLUDING TWO CANDIDATE SPECTROSCOPIC VARIABLES  

SciTech Connect (OSTI)

We present initial results from a wide-field (30,000 deg{sup 2}) search for L/T transition brown dwarfs within 25 pc using the Pan-STARRS1 and Wide-field Infrared Survey Explorer (WISE) surveys. Previous large-area searches have been incomplete for L/T transition dwarfs, because these objects are faint in optical bands and have near-infrared (near-IR) colors that are difficult to distinguish from background stars. To overcome these obstacles, we have cross-matched the Pan-STARRS1 (optical) and WISE (mid-IR) catalogs to produce a unique multi-wavelength database for finding ultracool dwarfs. As part of our initial discoveries, we have identified seven brown dwarfs in the L/T transition within 9-15 pc of the Sun. The L9.5 dwarf PSO J140.2308+45.6487 and the T1.5 dwarf PSO J307.6784+07.8263 (both independently discovered by Mace et al.) show possible spectroscopic variability at the Y and J bands. Two more objects in our sample show evidence of photometric J-band variability, and two others are candidate unresolved binaries based on their spectra. We expect our full search to yield a well-defined, volume-limited sample of L/T transition dwarfs that will include many new targets for study of this complex regime. PSO J307.6784+07.8263 in particular may be an excellent candidate for in-depth study of variability, given its brightness (J = 14.2 mag) and proximity (11 pc)

Distribution of rare earth elements in marine sediments from the Strait of Sicily (western Mediterranean Sea): Evidence of phosphogypsum waste contamination  

Science Journals Connector (OSTI)

Concentrations of rare earth elements (REE), Y, Th and Sc were recently determined in marine sediments collected using a box corer along two onshoreoffshore transects located in the Strait of Sicily (Mediterranean Sea). The REE+Y were enriched in offshore fine-grained sediments where clay minerals are abundant, whereas the REE+Y contents were lower in onshore coarse-grained sediments with high carbonate fractions. Considering this distribution trend, the onshore sediments in front of the southwestern Sicilian coast represent an anomaly with high REE+Y concentrations (mean value 163.4?gg?1) associated to high Th concentrations (mean value 7.9?gg?1). Plot of shale-normalized REE+Y data of these coastal sediments showed Middle REE enrichments relative to Light REE and Heavy REE, manifested by a convexity around SmGdEu elements. These anomalies in the fractionation patterns of the coastal sediments were attributed to phosphogypsum-contaminated effluents from an industrial plant, located in the southern Sicilian coast.

Comparison between continuous stirred tank reactor extractor and soxhlet extractor for extraction of El-Lajjun oil shale  

SciTech Connect (OSTI)

Extraction on El-Lajjun oil shale in a continuous stirred tank reactor extractor (CSTRE) and a Soxhlet extractor was carried out using toluene and chloroform as solvents. Solvents were recovered using two distillation stages, a simple distillation followed by a fractional distillation. Gas chromotography was used to test for the existence of trapped solvent in the yield. It was found that extraction using a CSTRE gave a 12% increase in yield on average compared with the Soxhlet extractor, and an optimum shale size of 1.0mm offered a better yield and solvent recovery for both techniques. It was also found that an optimum ratio of solvent to oil shale of 2:1 gave the best oil yield. The Soxhlet extractor was found to offer an extraction rate of 1 hour to complete extraction compared with 4 hours in a CSTRE. The yield in a CSTRE was found to increase on increase of stirring. When extraction was carried out at the boiling point of the solvents in a CSTRE, the yield was found to increase by 30% on average compared to that of extraction when the solvent was at room temperature. When toluene was used for extraction, the average amount of bitumen extracted was 0.032 g/g of oil shale and 76.4% of the solvent recovered, compared with 0.037 g/g of oil shale and 84.1% of the solvent recovered using a Soxhlet extractor.

The connection between 2006 IPCC GHG inventory methodology and ISO 14064-1 certification standard A reference point for the environmental policies at sub-national scale  

Science Journals Connector (OSTI)

Abstract The article shows how a joint application of the 2006 IPCC methodology and the ISO 14064-1 standard of certification, as well as the co-operation between academic, legislative and administrative organizations, are important points for a sustainable management of an administrative jurisdiction, providing positive environmental effects. The administrative systems can choose validated ISO 14064-1 GHG inventories, produced in time series, as a strategy tool for local management, as a compass to orient future policy decisions. The Province of Siena (Tuscany, Central Italy) was one regional system in Europe to achieve the ISO 14064-1 certification of its GHG inventories, developed in time series applying the 2006 IPCC methodology. The results of the time series (year 20062010) of GHG inventories elaborated for the Province of Siena point out that the performed environmental management policies may bring about a significant reduction of GHG emission released to the atmosphere over time (net emission: 449GgCO2eq in 2006, 84GgCO2eq in 2010). The experience of the Province of Siena can be considered a significant reference model for all public authorities at the micro and macro scale who are interested in reducing GHG emission.

AlFe PILC preparation, characterization and its potential adsorption capacity for aflatoxin B1  

Science Journals Connector (OSTI)

Abstract Montmorillonite (Mt) was used as the precursor material for synthesis of aluminumironpillared montmorillonite (AlFePMt) and the adsorption of aflatoxin B1 (AFB1) by Mt and AlFePMt was investigated. Different forms of polycations were prepared and used to modify Mt, when the molar ratio of Al3+ to Fe3+ was 8.0, AlFePMt obtained the maximum adsorption capacity of AFB1 (660.0?g/g) which was much higher than that of Mt (30.4?g/g). The adsorbents were characterized by XRD, SEM and FTIR, and the effects of adsorbent amount, pH and interaction time on the adsorption of AFB1 onto Mt and AlFePMt were also studied. Adsorption isotherm parameters were obtained from Langmuir and Freundlich and the adsorption data fitted better to Langmuir. The obtained results show that the great difference of adsorption capacity between Mt and AlFePMt mainly lies in their microstructure and chemical composition, and it suggests that AlFePMt is suitable to be used as a potential adsorbent to remove AFB1 from the contaminated products.

Production of single top-quark final states at the LHC from supersymmetric FCNC interactions  

E-Print Network [OSTI]

We discuss the production of single top-quark final states by direct supersymmetric flavor-changing interactions at the LHC. The total cross section pp(gg)->t\\bar{c}+\\bar{t}c is computed at the 1-loop order within the unconstrained MSSM. We prove that SUSY-QCD effects may furnish sizeable production rates amounting up to barely 10^5 t\\bar{c}(c\\bar{t}) events per 100 fb^{-1} of integrated luminosity, in full compliance with the stringent low-energy constraints from b->s gamma. Furthermore, we show that the cooperative SUSY-EW effects can be sizeable on their own, regardless of the SUSY-QCD contribution, with maximum production rates of the order of 10^3 events per 100 fb^{-1}. Owing to the fact that FCNC production of electrically neutral heavy-quark pairs is virtually absent within the SM, we conclude that the observation of such pp(gg)->t\\bar{c}+\\bar{t}c processes at the LHC could lead to evidence of new physics - of likely supersymmetric nature.

Let $L$ be an elliptic differential operator on a complete connected Riemannian manifold $M$ such that the associated heat kernel has two-sided Gaussian bounds as well as a Gaussian type gradient estimate. Let $L^{(\\aa)}$ be the $\\aa$-stable subordination of $L$ for $\\aa\\in (1,2).$ We found some classes $\\mathbb K_\\aa^{\\gg,\\bb} (\\bb,\\gg\\in [0,\\aa))$ of time-space functions containing the Kato class, such that for any measurable $b: [0,\\infty)\\times M\\to TM$ and $c: [0,\\infty)\\times M\\to M$ with $|b|, c\\in \\mathbb K_\\aa^{1,1},$ the operator $$L_{b,c}^{(\\aa)}(t,x):= L^{(\\aa)}(x)+ +c(t,x),\\ \\ (t,x)\\in [0,\\infty)\\times M$$ has a unique heat kernel $p_{b,c}^{(\\aa)}(t,x;s,y), 0\\le s1$, where $\\rr$ is the Riemannian distance.

Relationship between selenium body burdens and tissue concentrations in fish exposed to coal ash at the Tennessee Valley Authority Kingston spill site  

SciTech Connect (OSTI)

In December 2008, 4.1 million m3 of coal ash were released into the Emory and Clinch Rivers by the Tennessee Valley Authority (TVA) Kingston Fossil Plant. Coal ash contains several contaminants, including the bioaccumulative metalloid selenium (Se). Because Se is predominantly accumulated in aquatic organisms through dietary, rather than aqueous exposure, tissue-based toxicity thresholds for Se are currently being considered. The proposed threshold concentrations range between 4-9 g/g Se (dry wt.) in whole body fish, with a proposed fillet threshold of 11.8 g/g. In the present study we examined the spatial and temporal trends in Se bioaccumulation and examined the relationship between the Se content in fillets and in whole bodies of fish collected around the Kingston spill site to determine whether Se bioaccumulation was a significant concern at the ash spill site. While Se concentrations in fish (whole bodies and fillets) were elevated at sampling locations affected by the Kingston ash spill relative to reference locations, concentrations do not appear to be above risk thresholds and have not been increasing over the five year period since the spill. Our results are not only relevant to guiding the human health and ecological risk assessments at the Kingston ash spill site, but because of current national discussions on appropriate guidelines for Se in fish as well for the disposal of coal combustion wastes, our results are also relevant to the general understanding of Se bioaccumulation in contaminated water bodies.

Projection and Galaxy Clustering Fourier Spectra  

E-Print Network [OSTI]

Second order perturbation theory predicts a specific dependence of the bispectrum, or three-point correlation function in the Fourier transform domain, on the shape of the configuration of its three wave vector arguments, which can be taken as a signature of structure formed by gravitational instability. Comparing this known dependence on configuration shape with the weak shape dependence of the galaxy bispectrum has been suggested as an indication of bias in the galaxy distribution. However, to interpret results obtained from projected catalogs, we must first understand the effects of projection on this shape dependence. We present expressions for the projected power spectrum and bispectrum in both Cartesian and spherical geometries, and we examine the effects of projection on the predicted bispectrum with particular attention to the dependence on configuration shape. Except for an overall numerical factor, for Cartesian projection with characteristic depth $ \\Dstar $ there is little effect on the shape dependence of the bispectrum for wavelengths small compared to $ \\Dstar $ or projected wavenumbers $ q \\Dstar \\gg 1 $. For angular projection, a scaling law is found for spherical harmonic index $ \\ell \\gg 1 $, but there is always a mixing of scales over the range of the selection function. For large $ \\ell $ it is sufficient to examine a small portion of the sky.

Variable Speed of Light Cosmology, Primordial Fluctuations and Gravitational Waves  

E-Print Network [OSTI]

A variable speed of light (VSL) cosmology is developed with a spontaneous breaking of Lorentz invariance in the early universe. A non-minimal electromagnetic coupling to curvature and the resulting quantum electrodynamic vacuum polarization dispersive medium can produce $c\\gg c_0$ in the early universe, where $c_0$ is the measured speed of light today. Higher derivative curvature contributions to the effective gravitational action and quantum gravity vacuum polarization can produce a dispersive medium and a large increase in the speed of gravitational waves $c_g\\gg c_{g0}$ in the early universe, where $c_{g0}$ is the speed of gravitational waves today. The initial value problems of cosmology are solved: the horizon and flatness problems. The model predicts primordial scalar and tensor fluctuation spectral indices $n_s=0.96$ and $n_t=- 0.04$, respectively. The BICEP2 observation of $r=0.2$ yields $r/n_t=-5$ which is close to the single-field inflationary consistency condition $r/n_t=-8$.

The distribution of depleted uranium contamination in Colonie, NY, USA  

Science Journals Connector (OSTI)

Uranium oxide particles were dispersed into the environment from a factory in Colonie (NY, USA) by prevailing winds during the 1960s and '70s. Uranium concentrations and isotope ratios from bulk soil samples have been accurately measured using inductively coupled plasma quadrupole mass spectrometry (ICP-QMS) without the need for analyte separation chemistry. The natural range of uranium concentrations in the Colonie soils has been estimated as 0.72.1?gg?1, with a weighted geometric mean of 1.05?gg?1; the contaminated soil samples comprise uranium up to 50040?gg?1. A plot of 236U/238U against 235U/238U isotope ratios describes a mixing line between natural uranium and depleted uranium (DU) in bulk soil samples; scatter from this line can be accounted for by heterogeneity in the DU particulate. The end-member of DU compositions aggregated in these bulk samples comprises (2.050.06)נ10?3 235U/238U, (3.20.1)נ10?5 236U/238U, and (7.10.3)נ10?6 234U/238U. The analytical method is sensitive to as little as 50ngg?1 DU mixed with the natural uranium occurring in these soils. The contamination footprint has been mapped northward from site, and at least one third of the uranium in a soil sample from the surface 5cm, collected 5.1km NNW of the site, is DU. The distribution of contamination within the surface soil horizon follows a trend of exponential decrease with depth, which can be approximated by a simple diffusion model. Bioturbation by earthworms can account for dispersal of contaminant from the soil surface, in the form of primary uranium oxide particulates, and uranyl species that are adsorbed to organic matter. Considering this distribution, the total mass of uranium contamination emitted from the factory is estimated to be c. 4.8tonnes.

Study of Multi-Scale Cloud Processes Over the Tropical Western Pacific Using Cloud-Resolving Models Constrained by Satellite Data  

SciTech Connect (OSTI)

Clouds in the tropical western Pacific are an integral part of the large scale environment. An improved understanding of the multi-scale structure of clouds and their interactions with the environment is critical to the ARM (Atmospheric Radiation Measurement) program for developing and evaluating cloud parameterizations, understanding the consequences of model biases, and providing a context for interpreting the observational data collected over the ARM Tropical Western Pacific (TWP) sites. Three-dimensional cloud resolving models (CRMs) are powerful tools for developing and evaluating cloud parameterizations. However, a significant challenge in using CRMs in the TWP is that the region lacks conventional data, so large uncertainty exists in defining the large-scale environment for clouds. This project links several aspects of the ARM program, from measurements to providing improved analyses, and from cloud-resolving modeling to climate-scale modeling and parameterization development, with the overall objective to improve the representations of clouds in climate models and to simulate and quantify resolved cloud effects on the large-scale environment. Our objectives will be achieved through a series of tasks focusing on the use of the Weather Research and Forecasting (WRF) model and ARM data. Our approach includes: -- Perform assimilation of COSMIC GPS radio occultation and other satellites products using the WRF Ensemble Kalman Filter assimilation system to represent the tropical large-scale environment at 36 km grid resolution. This high-resolution analysis can be used by the community to derive forcing products for single-column models or cloud-resolving models. -- Perform cloud-resolving simulations using WRF and its nesting capabilities, driven by the improved regional analysis and evaluate the simulations against ARM datasets such as from TWP-ICE to optimize the microphysics parameters for this region. A cirrus study (Mace and co-authors) already exists for TWP-ICE using satellite and ground-based observations. -- Perform numerical experiments using WRF to investigate how convection over tropical islands in the Maritime Continent interacts with large-scale circulation and affects convection in nearby regions. -- Evaluate and apply WRF as a testbed for GCM cloud parameterizations, utilizing the ability of WRF to run on multiple scales (from cloud resolving to global) to isolate resolution and physics issues from dynamical and model framework issues. Key products will be disseminated to the ARM and larger community through distribution of data archives, including model outputs from the data assimilation products and cloud resolving simulations, and publications.

OECD MCCI project Small-Scale Water Ingression and Crust Strength Tests (SSWICS) SSWICS-1 test data report : thermal hydraulic results. Rev. 0 September 20, 2002.  

SciTech Connect (OSTI)

The Melt Attack and Coolability Experiments (MACE) program at Argonne National Laboratory addressed the issue of the ability of water to cool and thermally stabilize a molten core/concrete interaction (MCCI) when the reactants are flooded from above. These tests provided data regarding the nature of corium interactions with concrete, the heat transfer rates from the melt to the overlying water pool, and the role of noncondensable gases in the mixing processes that contribute to melt quenching. However, due to the integral nature of these tests, several questions regarding the crust freezing behavior could not be adequately resolved. These questions include: (1) To what extent does water ingression into the crust increase the melt quench rate above the conduction-limited rate and how is this affected by melt composition and system pressure and (2) What is the fracture strength of the corium crust when subjected to a thermal-mechanical load and how does it depend upon the melt composition? A series of separate-effects experiments are being conducted to address these issues. The first employs an apparatus designed to measure the quench rate of a pool of corium ({approx}{phi}30 cm; up to 20 cm deep). The main parameter to be varied in these quench tests is the melt composition since it is thought to have a critical influence on the crust cracking behavior which, in turn, alters quench rate. The issue of crust strength will be addressed with a second apparatus designed to mechanically load the crust produced by the quench tests. This apparatus will measure the fracture strength of the crust while under a thermal load created by a heating element beneath the crust. The two apparatuses used to measure the melt quench rate and crust strength are jointly referred to as SSWICS (Small-Scale Water Ingression and Crust Strength). This report describes results of the first water ingression test, designated SSWICS-1. The report includes a description of the test apparatus, the instrumentation used, plots of the recorded data, and some rudimentary data reduction to obtain an estimate of the heat flux from the corium to the overlying water pool.

These 6 layer magnets were designed to include the main quadrupole focus, a skew quad, a normal and skew dipole, and a final sextupole layer. Because of the physical space constraints imposed by the existing detector region components, the DESY magnets were of necessity designed to be very compact. In addition, they are also are required to operate within the solenoidal detector fields at the collision points, so all construction materials had to be non magnetic. Two types of DESY magnets were fabricated. The first, designated as G0, was a two meter long, constant radius magnet. The second, designated GG, is a

The tool consists of an ultrasonic transducer coupled with a downhole inclinometer. These devices are used to generate an oriented image of seismic velocity variation and wave amplitude. These images are then examined and highlighted to reveal fractures, bedding planes and orientation of those features. The log is useful for strata and fracture delineation, and can also be used to evaluate compressional-wave velocity, borehole deviation and eccentricity.[1] References ↑ http://www.dot.ca.gov/hq/esc/geotech/gg/atv_log.htm Ret LikeLike UnlikeLike You like this.Sign Up to see what your friends like.

Determination of Boron-Containing Compounds in Urine and Blood Plasma from Boron Neutron Capture Therapy Patients. The Importance of Using Coupled Techniques  

Science Journals Connector (OSTI)

Since only 10B (comprising 20% of elemental boron in nature) has the large cross-section for neutron capture reaction and is thereby useful for BNCT, the boron in the BPA transport molecules used in the Studsvik therapy was enriched with the 10B isotope to nearly 100%. ... A 1000 ?g/mL certified boric acid standard was purchased from BDH Chemicals (Poole, U.K.) and diluted to 2?10 ppm (?g/g) of boron in 0.1 M hydrochloric acid. ... To get a hint of the accuracy of the BPA determination, a spinach sample, IAEA-331, with a certified boron content of (37.6 1.0) mg kg-1 was digested in nitric acid in a steel bomb and determined with ICP-AES. ...

In situ global method for measurement of oxygen demand and mass transfer  

SciTech Connect (OSTI)

Two aerobic microorganisms, Saccharomycopsis lipolytica and Brevibacterium lactofermentum, have been used in a study of mass transfer and oxygen uptake from a global perspective using a closed gas system. Oxygen concentrations in the gas and liquid were followed using oxygen electrodes, and the results allowed for easy calculation of in situ oxygen transport. The cell yields on oxygen for S. lipolytica and B. lactofermentum were 1.01 and 1.53 g/g respectively. The mass transfer coefficient was estimated as 10 h{sup {minus}1} at 500 rpm for both fermentations. The advantages with this method are noticeable since the use of model systems may be avoided, and the in situ measurements of oxygen demand assure reliable data for scale-up.

Borexino: A real time liquid scintillator detector for low energy solar neutrino study  

E-Print Network [OSTI]

Borexino is a large unsegmented calorimeter featuring 300 tons of liquid scintillator, contained in a 8.5 meter nylon vessel, viewed by 2200 PMTs. The main goal of Borexino is the study, in real time, of low energy solar neutrinos, and in particular, the monoenergetic neutrinos coming from $^7Be$, which is one of the missing links on the solar neutrino problem. The achievement of high radiopurity level, in the order of $10^{-16} g/g$ of U/Th equivalent, necessary to the detection of the low energy component of the solar neutrino flux, was proved in the Borexino prototype: the Counting Test Facility. The detector is located underground in the Laboratori Nazionali del Gran Sasso in the center of Italy at 3500 meter water equivalent depth. In this paper the science and technology of Borexino are reviewed and its main capabilities are presented.

In particular, we focus on the dependence on the different values of the strong coupling, alpha_S(M_Z^2), used by each group. We also perform a comparison of the relevant quark-antiquark and gluon-gluon luminosity functions. We make some comments on the recent PDF4LHC recommendations. Finally, we discuss the comparison of data and theory for W and Z cross sections at the LHC.
