Herbs  

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

Herbs Herbs Nature Bulletin 471-A November 18, 1972 Forest Preserve District of Cook County George W. Dunne, President Roland F. Eisenbeis, Supt. of Conservation HERBS An herb, to a botanist, is a plant with tender stems -- they are not permanently woodly like those of a shrub. To most people, herbs are plants with fragrant stems and leaves, or pungent seeds, used in cooking, pickling, perfumes, or medicines. Their use for such purposes, particularly the latter, is as old as the hills and in every country there is a wealth of folklore, legends and superstitions about them. The early American colonists had herb gardens. They included several kinds of plants used to flavor foods and, especially, to disguise the taste of old half-spoiled meat. They also included many medicinal plants called "simples", or "Physio Herbs", used in home remedies for all sorts of ailments.

Csaba Horvath and preparative liquid chromatography  

SciTech Connect

Few chromatographers have been interested in furthering preparative liquid chromatography. The pioneers, Tswett, Kuhn and Lederer, A.J.P. Martin, Tiselius, isolated fractions but as an intermediate step in the analysis of their samples. The progress in electronics and sensors, and in their miniaturization has lead to the paradoxical situation that the analysts never see the transient pure fractions that their detector quantitates. Yet, over the last 25 years, preparative liquid chromatography has become an important industrial process for the separation, the extraction, and/or the purification of many pharmaceuticals or pharmaceutical intermediates, including pure enantiomers, purified peptides and proteins, compounds that are manufactured at the relatively large industrial scale of a few kilograms to several hundred tons per year. This development that has strongly affected the modern pharmaceutical industry is mainly due to the pioneering work of Csaba Horvath. His work in preparative HPLC was critical at both the practical and the theoretical levels. He was the first scientist in modern times to pay serious attention to the relationships between the curvature of the equilibrium isotherms, the competitive nature of nonlinear isotherms, and the chromatographic band profiles of complex mixtures. The thermodynamics of multi-component phase equilibria and mass transfer kinetics in chromatography attracted his interest and were the focus of ground-breaking contributions. He investigated displacement chromatography, an old method invented by Tiselius that Csaba was first to implement in HPLC. This choice was explained by the essential characteristic of displacement chromatography, in that it delivers fractions that can be far more concentrated than the feed. Remarkably, once the basics of nonlinear chromatography had been mastered in his group, most of the applications that were studied by his coworkers dealt with peptides of various sizes and with proteins. Thus, all the applications of preparative HPLC in the biotechnologies derive directly from Csaba's work. Although displacement did not pan out as a general method, the reasons are related more to practical constraints of the production of pharmaceuticals and to the long period of cheap energy that might be ending now. This report reviews Csaba's work in nonlinear chromatography.

Evaluation of antioxidative/antimicrobial potential of Oriental nutraceutical herb extracts in raw and cooked goat meat and beef products  

E-Print Network (OSTI)

This study was conducted to determine the effects of alcohol extracts of several Oriental nutraceutical herbs on storage properties of raw and cooked ground goat meat and beef. White peony root, red peony root, sappanwood stem, rehmania root, moutan cortex root, angelica root, and rosemary leaves were dehydrated, extracted with 95% ethanol, and freed of the solvent. The sappanwood, moutan cortex, and rosemary samples contained the largest amounts of total phenolics. Extracts were added to ground goat meat, and treated meat samples were aerobically stored at 4C for 6 days, with or without cooking. Each herbal extract was also added to ground beef at 0.25% (w/w), with or without adding NaCl at 2% (w/w), and stored as raw and cooked patties. Peony (red or white) root extracts, whether added at 0.5, 1, or 2% levels, showed strong antioxidant effects in cooked goat meat, decreasing TBARS content more than 90% at day 6. The extracts were less antioxidative in raw goat meat, lowering the day-6 TBARS content less than 50%. The extracts from rehmania root, sappanwood, and moutan cortex were as antioxidative as the extracts from red and white peony roots, decreasing the TBARS content in cooked goat meat more than 88% at day 6. When red peony root extract was evaluated for antimicrobial activity in raw goat meat, it decreased APCs at day 3, but not at day 6. Extracts from white and red peony roots, sappanwood, moutan cortex, and rosemary were highly antioxidative in both raw and cooked beef patties, decreasing TBARS more than 88% by day 6. However, rehmania and angelica root extracts were less inhibitory. The antioxidant activity of the herbal extracts correlated (P 0.05) with total phenolic levels. All the extracts, other than rosemary extract, showed no antimicrobial activity in raw beef patties at either day 3 or day 6, presumably due to the relatively high microbial counts found in the initial untreated meat. Rosemary extract decreased APCs only at day 3.

Pueblo of Jemez Geothermal Feasibility Study Fianl Report  

DOE Green Energy (OSTI)

This project assessed the feasibility of developing geothermal energy on the Pueblo of Jemez, with particular attention to the Red Rocks area. Geologic mapping of the Red Rocks area was done at a scale of 1:6000 and geophysical surveys identified a potential drilling target at a depth of 420 feet. The most feasible business identified to use geothermal energy on the reservation was a greenhouse growing culinary and medicinal herbs. Space heating and a spa were identified as two other likely uses of geothermal energy at Jemez Pueblo. Further geophysical surveys are needed to identify the depth to the Madera Limestone, the most likely host for a major geothermal reservoir.

Bible Bible Nature Bulletin No. 188-A April 16, 1965 Forest Preserve District of Cook County Seymour Simon, President Roland F. Eisenbeis, Supt. of Conservation PLANTS OF THE BIBLE When Jesus suffered on the cross, we are told in the Gospel according to St. Matthew (27:48) that at the ninth hour he thirsted and a sponge, filled with vinegar and put upon a reed, was raised to His lips. It is so related in St. Mark (15:36) but according to St. John (19:29), "they filled a sponge with vinegar, and put it upon hyssop, and put it into his mouth. " What was hyssop. The plant is mentioned frequently in the Bible. The hyssop of our herb gardens is not native to Palestine, Syria or Egypt, but there is evidence that when Solomon "spoke of trees, from the cedar tree that is in Lebanon even unto the hyssop that springeth out of the wall" (I Kings 4:23), he spoke of the herb we call marjoram. The hyssop dipped in the blood of a sacrificial lamb and used by the Israelites in Egypt to mark their doorways (Exodus 12:22), and the hyssop referred to by St. John but called a reed by St. Matthew and St. Mark, was probably sorghum, a tall cereal plant grown by the Jews for food and also used for brushes and brooms.

Smoking, Drinking, and Income  

E-Print Network (OSTI)

A growing literature identifies a beneficial effect of moderate and even heavy drinking on wages and a negative effect of smoking on wages. An outstanding issue is whether these results obtain because of a causal effect of substance use on wages or whether the observed correlations reflect the effects of income on consumption or other endogeneity problems. This paper presents full information estimates of the structural parameters of a simultaneous model of drinking and smoking status and income using repeated cross--section data. With all else in the system held constant, both smoking and drinking behaviour still have large effects on income, and the income elasticities of smoking and drinking are shown to be larger in magnitude when controlling for endogeneity.

Distribution and conservation significance of endemic species of flowering plants in Peru  

E-Print Network (OSTI)

Abstract. Using the data published in the Catalogue of the Flowering Plants and Gymnosperms of Peru, we analyzed the elevational distributions of 5323 species reported as endemics from that country as a whole, for 10 families with the highest number of endemic taxa in Peru, and the distribution patterns of these species according to life form. We calculated the density of endemism (number of endemic species divided by area 1000) and absolute number of endemic species among life forms and families, along an elevational gradient. Overall densities of endemics were 1015 times higher at mid-elevation (2000 3500 m) than in the Amazonian lowlands (0500 m). Absolute numbers of endemics peaked at 1500 3000 m for herbs, shrubs, and epiphytes, while trees, vines, and lianas showed maxima in the lowlands (0500 m); yet densities of endemics for all life forms peaked at 15003000 m. Among the 10 families with the highest number of endemics, densities of endemics peaked at mid- to high elevation (1500 4500 m), but showed much disparity in the elevational distribution of absolute numbers of endemic species. Finally, the percentage of endemic species to total species is highest for herbs, shrubs, and epiphytes. Given that less than 10 % of the land area for each of the montane zones (20004500 m) is protected compared to 13.529.9 % in the lower elevations (01000 m), we recommend that priority be given to increasing the size of protected areas at mid- to high altitude in the Andean slopes to grant further protection in zones with the highest density of endemics. We also recommend that more emphasis be given to collecting and studying non-trees, since most endemic species belong to that class.

Habitat Evaluation Procedures (HEP) Report Wanaket Wildlife Area, Techical Report 2005-2006.  

DOE Green Energy (OSTI)

The Regional HEP Team (RHT) and Confederated Tribes of the Umatilla Indian Reservation (CTUIR) Wildlife Program staff conducted a follow-up habitat evaluation procedures (HEP) analysis on the Wanaket Wildlife Management Area in June 2005. The 2005 HEP investigation generated 3,084.48 habitat units (HUs) for a net increase of 752.18 HUs above 1990/1995 baseline survey results. The HU to acre ratio also increased from 0.84:1.0 to 1.16:1.0. The largest increase in habitat units occurred in the shrubsteppe/grassland cover type (California quail and western meadowlark models), which increased from 1,544 HUs to 2,777 HUs (+43%), while agriculture cover type HUs were eliminated because agricultural lands (managed pasture) were converted to shrubsteppe/grassland. In addition to the agriculture cover type, major changes in habitat structure occurred in the shrubsteppe/grassland cover type due to the 2001 wildfire which removed the shrub component from well over 95% of its former range. The number of acres of all other cover types remained relatively stable; however, habitat quality improved in the riparian herb and riparian shrub cover types. The number and type of HEP species models used during the 2005 HEP analysis were identical to those used in the 1990/1995 baseline HEP surveys. The number of species models employed to evaluate the shrubsteppe/grassland, sand/gravel/mud/cobble, and riparian herb cover types, however, were fewer than reported in the McNary Dam Loss Assessment (Rassmussen and Wright 1989) for the same cover types.

Medicinal Plants Medicinal Plants Nature Bulletin No. 187 April 11, 1981 Forest Preserve District of Cook County George W. Dunne, President Roland F. Eisenbeis, Supt. of Conservation MEDICINAL PLANTS In springtime, many years ago, grandma made her family drink gallons of tea made by boiling roots of the sassafras. That was supposed to thin and purify the blood. Children were sent out to gather dandelion, curly dock, wild mustard, pokeberry and other greens as soon as they appeared -- not only because they added welcome variety to the diet of bread, meat, potatoes and gravy, but because some of them were also laxatives. For a bad "cold on the lungs," she slapped a mustard plaster on the patient's back, and on his chest she put a square of red flannel soaked in goose grease. For whooping cough she used a syrup of red clover blossoms. She made cough medicine from the bloodroot plant, and a tea from the compass plant of the prairies was also used for fevers and coughs. She made a pleasant tea from the blossoms of the linden or basswood tree. For stomach aches she used tea from any of several aromatic herbs such as catnip, fennel, yarrow, peppermint, spearmint, sweetflag, wild ginger, bergamot and splice bush.

Seed Numbers Seed Numbers Name: Dan Status: student Grade: n/a Location: N/A Country: USA Date: Summer 2011 Question: Why do some seed plants produce numerous seeds, while others just one? Replies: Hi Dan, When a plant produces seed, the purpose is to carry on the species - to produce more plants. The strategy employed by the plant will vary depending on the environment in which the plant has developed, but in the main there are two main strategies which I categorize in my head as "Special Care" and "Safety in Numbers". "Safety In Numbers" is how the dandelion chooses to tackle the problem. It produces huge numbers of seeds, and does very little to help those seeds other than to make sure they get away from the parent plant (That's trhe job of the parachute) Other plants which use this strategy include most herbs such as mint, borage, dill where the seeds are very small, and are produced in huge numbers.

Mint Family Mint Family Nature Bulletin No. 432-A November 6, 1971 Forest Preserve District of Cook County George W. Dunne, President Roland F. Eisenbeis, Supt. of Conservation THE MINT FAMILY The Mint Family, in addition to the true mints -- such as Spearmint used in flavoring chewing gum and the mint sauce traditionally served with roast lamb -- contains over 3000 species. Almost all of them are plants with square stems and opposite pairs or whorls of leaves at intervals along the stems. Most of them have a distinctive fragrant or pungent odor, due to volatile oils contained in glands or sacs in the leaves and other parts. Through the ages, the mints have been variously used by man for medicinal purposes and flavorings. Lavender, rosemary and patchouli are perfumes obtained from members of this family. The lemon-scented leaves of Bergamot, one of the true mints, furnish a fragrant oil also used in perfumes. A surprising number of the savories or kitchen herbs used in cooking are plants belonging to this aromatic tribe: sage, thyme, germander, marjoram, the basils, summer savory and hyssop.

Banana Trees

Banana Trees Banana Trees Name: Adele Location: N/A Country: N/A Date: N/A Question: Why do Banana trees grow bananas?? I've been asked this question and no-one I know can provide an answer! Bananas do not have seeds in them to reproduce the tree (e.g you can grow a lemon tree from the seeds in the fruit but not a banana tree from a banana) What evolutionary justification is there for a banana tree to bear fruit? Replies: Hi Adele! you are right, one cannot seed a banana tree, still that kind of vegetal is reproduced and grows... As many other plants they have an asexual reproduction, where the new plants are identical in every respect to the parent plant.The asexual reproduction involves no union of cells or nuclei of cells, there are not mingling of genetic traits. Banana plant is a gigantic herb that grows from an under- ground stem ( rhizome),and forms a false trunk with leaves. There emerges a large flower spike, with numerous individual flowers, that bends downward to become fruits. After the plants had fruits, they die and are replaced by others that arise from the underground stem, and that process can keep on going for many years. Right?

Restoring a disappearing ecosystem: the Longleaf Pine Savanna.  

SciTech Connect

Longleaf pine (Pinus palustris) savannas of the southeastern United States contain some of the worlds most diverse plant communities, along with a unique complement of wildlife. Their traditionally open canopy structure and rich understory of grasses and herbs were critical to their vigor. However, a long history of land-use practices such as logging, farming, and fire exclusion have reduced this once-widespread ecosystem to only 3 percent of its original range. At six longleaf pine plantations in South Carolina, Tim Harrington with the Pacific Northwest Research Station and collaborators with the Southern Research Station used various treatments (including prescribed burns, tree thinning, and herbicide applications) to alter the forest structure and tracked how successful each one was in advancing savanna restoration over a 14-year period. They found that typical planting densities for wood production in plantations create dense understory shade that excludes many native herbaceous species important to savannas and associated wildlife. The scientists found that although tree thinning alone did not result in sustained gains, a combination of controlled burning, thinning, and herbicide treatments to reduce woody plants was an effective strategy for recovering the savanna ecosystem. The scientists also found that these efforts must be repeated periodically for enduring benefits.

Pipeline corridors through wetlands - impacts on plant communities: Bayou Grand Cane, De Soto Parish, Louisiana. Topical report, August 1991--July 1993  

SciTech Connect

The goal of the Gas Research Institute Wetland Corridors Program is to document impacts of existing pipeline on the wetlands they traverse. To accomplish this goal, 12 existing wetland crossings were surveyed. These sites varied in elapsed time since pipeline construction, wetland type, pipeline installation techniques, and night of-way (ROW) management practices. This report presents the results of a survey conducted over the period of August 12-13, 1991, at the Bayou Grand Cane crossing in De Soto Parish, Louisiana, where a pipeline constructed three years prior to the survey crosses the bayou through mature bottomland hardwoods. The sit was not seeded or fertilized after construction activities. At the time of sampling, a dense herb stratum (composed of mostly native species) covered the 20-m-wide ROW, except within drainage channels. As a result of the creation of the ROW, new habitat was created, plant diversity increased, and forest habitat became fragmented. The ROW must be maintained at an early stage of succession to allow access to the pipeline however, impacts to the wetland were minimized by decreasing the width of the ROW to 20 m and recreating the drainage channels across the ROW. The canopy trees on the ROW`s edge shaded part of the ROW, which helped to minimize the effects of the ROW.

Puerariae radix isoflavones and their metabolites inhibit growth and induce apoptosis in breast cancer cells  

SciTech Connect

Puerariae radix (PR) is a popular natural herb and a traditional food in Asia, which has antithrombotic and anti-allergic properties and stimulates estrogenic activity. In the present study, we investigated the effects of the PR isoflavones puerarin, daidzein, and genistein on the growth of breast cancer cells. Our data revealed that after treatment with PR isoflavones, a dose-dependent inhibition of cell growth occurred in HS578T, MDA-MB-231, and MCF-7 cell lines. Results from cell cycle distribution and apoptosis assays revealed that PR isoflavones induced cell apoptosis through a caspase-3-dependent pathway and mediated cell cycle arrest in the G2/M phase. Furthermore, we observed that the serum metabolites of PR (daidzein sulfates/glucuronides) inhibited proliferation of the breast cancer cells at a 50% cell growth inhibition (GI{sub 50}) concentration of 2.35 {mu}M. These results indicate that the daidzein constituent of PR can be metabolized to daidzein sulfates or daidzein glucuronides that exhibit anticancer activities. The protein expression levels of the active forms of caspase-9 and Bax in breast cancer cells were significantly increased by treatment with PR metabolites. These metabolites also increased the protein expression levels of p53 and p21. We therefore suggest that PR may act as a chemopreventive and/or chemotherapeutic agent against breast cancer by reducing cell viability and inducing apoptosis.

Ogilvie, President Roland F. Eisenbeis, Supt. of Conservation APPLES AND OTHER FRUITS OF THE ROSE FAMILY Bread, meat and potatoes, with vegetables and green salads, may satisfy the inner man and keep us healthy but much of the fun of eating is provided by the rose family. The rose, itself, is the flower of chivalry and love but its relative, the apple, king of the fruits, has been cultivated since prehistoric times. The members of the Rose Family give us more pleasure than we get from any other group of plants. Apples, quinces, pears, peaches, plums, apricots, cherries, blackberries, raspberries and strawberries -- whether wild or cultivated -- are all relatives of the roses. Their fruits, raw or cooked, give us desserts, pleasant drinks, and many a between-meal delicacy. Typically, they have showy flowers with five equal petals arranged around a central cup bearing one or more fruit-forming pistils and a large number of pollen-bearing stamens. Their leaves are placed alternately on the twigs or stalks -- some of them simple leaves; some of them compound leaves divided into three, five or more leaflets like the rose itself. Some are trees, some are shrubs, and some are vining herbs.

Dual mechanisms of NF-kappaB inhibition in carnosol-treated endothelial cells  

Science Conference Proceedings (OSTI)

The increased adhesion of monocytes to injured endothelial layers is a critical early event in atherogenesis. Under inflammatory conditions, there is increased expression of specific cell adhesion molecules on activated vascular endothelial cells, which increases monocyte adhesion. In our current study, we demonstrate a putative mechanism for the anti-inflammatory effects of carnosol, a diterpene derived from the herb rosemary. Our results show that both carnosol and rosemary essential oils inhibit the adhesion of TNFalpha-induced monocytes to endothelial cells and suppress the expression of ICAM-1 at the transcriptional level. Moreover, carnosol was found to exert its inhibitory effects by blocking the degradation of the inhibitory protein IkappaBalpha in short term pretreatments but not in 12 h pretreatments. Our data show that carnosol reduces IKK-beta phosphorylation in pretreatments of less than 3 h. In TNFalpha-treated ECs, NF-kappaB nuclear translocation and transcriptional activity was abolished by up to 12 h of carnosol pretreatment and this was blocked by Nrf-2 siRNA. The long-term inhibitory effects of carnosol thus appear to be mediated through its induction of Nrf-2-related genes. The inhibition of ICAM-1 expression and p65 translocation is reversed by HO-1 siRNA. Carnosol also upregulates the Nrf-2-related glutathione synthase gene and thereby increases the GSH levels after 9 h of exposure. Treating ECs with a GSH synthesis inhibitor, BSO, blocks the inhibitory effects of carnosol. In addition, carnosol increases p65 glutathionylation. Hence, our present findings indicate that carnosol suppresses TNFalpha-induced singling pathways through the inhibition of IKK-beta activity or the upregulation of HO-1 expression. The resulting GSH levels are dependent, however, on the length of the carnosol pretreatment period.

Quantifying biological integrity of California sage scrub communities using plant life-form cover.  

SciTech Connect

The California sage scrub (CSS) community type in California's Mediterranean-type ecosystems supports a large number of rare, threatened, and endangered species, and is critically degraded and endangered. Monitoring ecological variables that provide information about community integrity is vital to conserving these biologically diverse communities. Fractional cover of true shrub, subshrub, herbaceous vegetation, and bare ground should fill information gaps between generalized vegetation type maps and detailed field-based plot measurements of species composition and provide an effective means for quantifying CSS community integrity. Remote sensing is the only tool available for estimating spatially comprehensive fractional cover over large extent, and fractional cover of plant life-form types is one of the measures of vegetation state that is most amenable to remote sensing. The use of remote sensing does not eliminate the need for either field surveying or vegetation type mapping; rather it will likely require a combination of approaches to reliably estimate life-form cover and to provide comprehensive information for communities. According to our review and synthesis, life-form fractional cover has strong potential for providing ecologically meaningful intermediate-scale information, which is unattainable from vegetation type maps and species-level field measurements. Thus, we strongly recommend incorporating fractional cover of true shrub, subshrub, herb, and bare ground in CSS community monitoring methods. Estimating life-form cover at a 25 m x 25 m spatial scale using remote sensing would be an appropriate approach for initial implementation. Investigation of remote sensing techniques and an appropriate spatial scale; collaboration of resource managers, biologists, and remote sensing specialists, and refinement of protocols are essential for integrating life-form fractional cover mapping into strategies for sustainable long-term CSS community management.

Manhattan Project: Final Bomb Design, Los Alamos: Laboratory, 1944-1945  

Office of Scientific and Technical Information (OSTI)

The first 0.11 seconds of the nuclear age, Trinity, July 16, 1945. FINAL BOMB DESIGN The first 0.11 seconds of the nuclear age, Trinity, July 16, 1945. FINAL BOMB DESIGN (Los Alamos: Laboratory, 1944-1945) Events > Bringing It All Together, 1942-1945 Establishing Los Alamos, 1942-1943 Early Bomb Design, 1943-1944 Basic Research at Los Alamos, 1943-1944 Implosion Becomes a Necessity, 1944 Oak Ridge and Hanford Come Through, 1944-1945 Final Bomb Design, 1944-1945 Atomic Rivals and the ALSOS Mission, 1938-1945 Espionage and the Manhattan Project, 1940-1945 American troops approaching the beach, D-Day, June 6, 1944. Late in 1944, Los Alamos began to shift from research to development and bomb production. Increased production at Oak Ridge and Hanford seemed to promise that enough plutonium and enriched uranium would be available for at least one bomb using each. Germany no longer was the intended primary target. The war in Europe (left) appeared to be entering its final phase, and evidence uncovered by the ALSOS mission in November 1944 indicated that the German atomic program had not gone beyond the research phase. Already by summer 1944, Groves and his advisers had turned their sights toward Japan. The atomic bomb would justify the years of effort, including both the vast expenditures and the judgment of everyone responsible, by bringing the war in the Pacific to a fiery end. J. Robert Oppenheimer Ongoing problems continued to complicate the efforts of Robert Oppenheimer (right) to finalize bomb design. Foremost among these were continuing personnel shortages, particularly of physicists, and supply difficulties. The procurement system, designed to protect the secrecy of the Los Alamos project, led to frustrating delays and, when Herb Lehr, SED, holding the Gadget's core, July 1945. combined with persistent late war shortages, proved a constant headache. The lack of contact between the remote laboratory and its supply sources exacerbated the problem, as did the relative lack of experience the academic scientists had with logistical matters. Leslie Groves and James Conant were determined not to let mundane problems compromise the bomb effort, and in fall 1944 they made several changes to prevent this possibility. Conant shipped as many scientists as could be spared from the Met Lab and Oak Ridge to Los Alamos, hired every civilian machinist he could lay his hands on, and arranged for Army enlisted men to supplement the work force (these GIs were known as SEDS ("Special Engineering Detachment"). Hartley Rowe, an experienced industrial engineer, provided help in easing the transition from research to production. Los Alamos also arranged for a rocket research team at the California Institute of Technology to aid in procurement, test fuses, and contribute to component development. These changes kept Los Alamos on track as design work reached its final stages.

Operational restoration of the Pen Branch bottomland hardwood and swamp wetlands - the research setting  

Science Conference Proceedings (OSTI)

The Savannah River Swamp is a 3020 Ha forested wetland on the floodplain of the Savannah River and is located on the Department of Energy's Savannah River Site (SRS) near Aiken, SC. Historically the swamp consisted of approximately 50 percent bald cypress-water tupelo stands, 40 percent mixed bottomland hardwood stands, and 10 percent shrub, marsh, and open water. Creek corridors were typical of Southeastern bottomland hardwood forests. The hydrology was controlled by flooding of the Savannah River and by flow from four creeks that drain into the swamp prior to flow into the Savannah River. Upstream dams have caused some alteration of the water levels and timing of flooding within the floodplain. Major impacts to the swamp hydrology occurred with the completion of the production reactors and one coal-fired powerhouse at the SRS in the early 1950's. Water was pumped from the Savannah River, through secondary heat exchangers of the reactors, and discharged into three of the tributary streams that flow into the swamp. Flow in one of the tributaries, Pen Branch, was typically 0.3 m3 s-1 (10-20) cfs prior to reactor pumping and 11.0 m3 s-1 (400 cfs) during pumping. This continued from 1954 to 1988 at various levels. The sustained increases in water volume resulted in overflow of the original stream banks and the creation of additional floodplains. Accompanying this was considerable erosion of the original stream corridor and deposition of a deep silt layer on the newly formed delta. Heated water was discharged directly into Pen Branch and water temperature in the stream often exceeded 65 degrees C. The nearly continuous flooding of the swamp, the thermal load of the water, and the heavy silting resulted in complete mortality of the original vegetation in large areas of the floodplain. In the years since pumping was reduced, early succession has begun in some affected areas. Most of this has been herbs, grasses, and shrubs. Areas that have seedlings are generally willow thickets that support a lower diversity of wildlife. No volunteer seedlings of heavy-seeded hardwoods or cypress have been found in the corridor areas. Research was conducted to determine methods to reintroduce tree species characteristic of more mature forested wetlands. Three restoration strategies were formulated to deal with the differing conditions of the Upper Corridor, the Lower Corridor, and the Delta regions of the impacted area. Site preparation and planting of each area with mixtures of tree species were carried out to speed the restoration of the ecosystem. Species composition and selection were altered based on the current and expected hydrological regimes that the reforestation areas will be experiencing. Because of the operational design of the restoration project, a research program naturally followed to document the success. Many of those efforts are detailed here.

The Role of Disturbance in Dry Tropical Forest Landscapes  

Science Conference Proceedings (OSTI)

Disturbance can be defined as 'any relatively discrete event in time that disrupts ecosystem, community, or population structure and changes resources, substrate availability, or the physical environment'. This definition requires that the spatial and temporal scales of the system and disturbance be determined. Disturbances are typically characterized by their size, spatial distribution, frequency or return time, predictability, and magnitude (which includes both intensity and severity). These disturbance attributes set the parameters for the suite of species, both plant and animal, that can persist within a given system. As such, an understanding of seasonally dry tropical forests in Asia requires an understanding of disturbance within the region. However, disturbances are relatively poorly understood in dry tropical forests, partly because of the weak seasonality in temperature and high tree species diversity of these forests relative to most forest systems of the world. There are about 1,048,700 km{sup 2} of dry tropical forests worldwide and that only 3% of this land is in conservation status. In other words, 97% of the world's seasonally dry tropical forest is at risk of human disturbance. About half of this forest occurs in South America, where most of the conservation lands are located. Satellite imagery based on MODIS (Moderate Resolution Imaging Spectroradiometer) data shows that only about 3.8% of the world's dry tropical forests are in Australia and South east Asia. The susceptibility of these forests to human disturbances is of great concern and is largely unstudied. Because natural disturbance regimes shape the ecosystem structure and are in many ways integral to these forest systems, it is critical to know how natural disturbance affects dry forest in order to understand the effects of human activities on these forests. Even basic information about disturbances in dry tropical forests is only recently available. Therefore this chapter brings together much of the available information from dry tropical forest throughout the world with the goal of developing an understanding of the role of disturbance in Asian dry forests. Most ecologists now recognize that disturbances, rather than being catastrophic agents of destruction, are a normal, perhaps even an integral, part of long-term system dynamics. The composition, structure, organization, and development and trophic dynamics of most forest systems are the products of disturbances. As an example, the forest composition for two disturbances in the Anaikatty Hills of Western Ghats were compared, where the low disturbance was from past logging followed by cutting and illicit felling and grazing and the high disturbance was due to human presence, past logging, and fuelwood collection. They found higher species richness and Shannon-Wiener diversity index for the low-disturbance forest (98 and 3.9, respectively) compared to the high-disturbance stand (45 and 2.71, respectively) as well as significant differences in mean basal area of trees, density of seedlings, number of species, density and diversity of shrubs, and number of species and diversity of herbs. Some ecological systems contain species that have evolved in response to disturbances. Adaptations typical of dry tropical forest plants are drought tolerance, seed dispersal mechanisms, and the ability to sprout subsequent to disturbance. In contrast, evidence was found that human disturbance in Kakamega Forest of western Kenya has significantly reduced allelic richness and heterozygosity, increased inbreeding, and slightly reduced gene flow in Prunus africana in the past century.

SNO: solving the mystery of the missing neutrinos  

DOE Green Energy (OSTI)

The end of an era came on 28 November 2006 when the Sudbury Neutrino Observatory (SNO) finally stopped data-taking after eight exciting years of discoveries. During this time the Observatory saw evidence that neutrinos, produced in the fusion of hydrogen in the solar core, change flavour while passing through the Sun on their way to the Earth. This observation explained the longstanding puzzle as to why previous experiments had seen fewer solar neutrinos than predicted and confirmed that these elusive particles have mass. Solar neutrinos were first detected in Ray Davis's radiochemical experiment in 1967, for which discovery he shared the 2002 Nobel Prize in Physics. Surprisingly he found only about a third of the number predicted from models of the Sun's output. This deficit, the so-called Solar Neutrino Problem, was confirmed by Kamiokande-II while other experiments saw related deficits of solar neutrinos. A possible explanation for this deficit, suggested by Gribov and Pontecorvo in 1969, was that some of the electron-type neutrinos, which are produced in the Sun, had ''oscillated'' into neutrinos that could not be detected in the Davis detector. The oscillation mechanism requires that neutrinos have non-zero mass. The unique advantage, which was pointed out by the late Herb Chen in 1985, of using heavy water (D{sub 2}O) to detect the neutrinos from {sup 8}B decays in the solar fusion process is that it enables both the number of electron-type and of all types of neutrinos to be measured. A comparison of the flux of electron-type neutrinos to that of all flavours could then reveal whether flavour transformation is the cause of the solar neutrino deficit. In heavy water neutrinos of all types can break a deuteron apart into its constituent proton and neutron (neutral-current reaction), while only electron-type neutrinos can change the deuteron into two protons and release an electron (charged-current reaction). SNO was designed by scientists from Canada, the USA and the UK to attain a detection rate of about 10 solar neutrinos per day using 1000 tonnes of heavy water. Neutrino interactions were detected by 9,456 photomultiplier tubes surrounding the heavy water, which was contained in a 12-m diameter acrylic sphere. This sphere was surrounded by 7000 tonnes of ultra-pure water to shield against radioactivity. Figure 1 shows the layout of the SNO detector, which is located about 2 km underground in Inco's Creighton nickel mine near Sudbury in Canada, to all but eliminate cosmic rays from reaching the detector. The pattern of hit photomultiplier tubes following the creation of an electron by an electron-type neutrino is shown in Figure 2.

Integration of the Mini-Sulfide Sulfite Anthraquinone (MSS-AQ) Pulping Process and Black Liquor Gasification in a Pulp Mill  

Science Conference Proceedings (OSTI)

As many of the recovery boilers and other pieces of large capital equipment of U.S. pulp mills are nearing the end of their useful life, the pulp and paper industry will soon need to make long-term investments in new technologies. The ability to install integrated, complete systems that are highly efficient will impact the industrys energy use for decades to come. Developing a process for these new systems is key to the adoption of state-of-the-art technologies in the Forest Products industry. This project defined an integrated process model that combines mini-sulfide sulfite anthraquinone (MSS-AQ) pulping and black liquor gasification with a proprietary desulfurization process developed by the Research Triangle Institute. Black liquor gasification is an emerging technology that enables the use of MSS-AQ pulping, which results in higher yield, lower bleaching cost, lower sulfur emissions, and the elimination of causticization requirements. The recently developed gas cleanup/absorber technology can clean the product gas to a state suitable for use in a gas turbine and also regenerate the pulping chemicals needed to for the MSS-AQ pulping process. The combination of three advanced technologies into an integrated design will enable the pulping industry to achieve a new level of efficiency, environmental performance, and cost savings. Because the three technologies are complimentary, their adoption as a streamlined package will ensure their ability to deliver maximum energy and cost savings benefits. The process models developed by this project will enable the successful integration of new technologies into the next generation of chemical pulping mills. When compared to the Kraft reference pulp, the MSS-AQ procedures produced pulps with a 10-15 % yield benefit and the ISO brightness was 1.5-2 times greater. The pulp refined little easier and had a slightly lower apparent sheet density (In both the cases). At similar levels of tear index the MSS-AQ pulps also produced a comparable tensile and burst index pulps. Product gas composition determined using computer simulations The results demonstrate that RVS-1 can effectively remove > 99.8% of the H2S present in simulated synthesis gas generated from the gasification of black liquor. This level of sulfur removal was consistent over simulated synthesis gas mixtures that contained from 6 to 9.5 vol % H2S.A significant amount of the sulfur in the simulated syngas was recovered as SO2 during regeneration. The average recovery of sulfur as SO2 was about 75%. Because these are first cycle results, this sulfur recovery is expected to improve. Developed WINGems model of the process.The total decrease in variable operating costs for the BLG process compared to the HERB was in excess of $6,200,000 per year for a mill producing 350,000 tons of pulp per year. This represents a decrease in operating cost of about $17.7/ton of oven dry pulp produced. There will be additional savings in labor and maintenance cost that has not been taken into account. The capital cost for the MSSAQ based gasifier system was estimated at $164,000,000, which is comparable to a High Efficiency Recovery Boiler. The return on investment was estimated at 4%. A gasifier replacement cannot be justified on its own, however if the recovery boiler needs to be replaced the MSSAQ gasifier system shows significantly higher savings. Before black liquor based gasifer technology can be commercialized more work is necessary. The recovery of the absorbed sulfur in the absorbent as sulfur dioxide is only 75%. This needs to be greater than 90% for economical operation. It has been suggested that as the number of cycles is increased the sulfur dioxide recovery might improve. Further research is necessary. Even though a significant amount of work has been done on a pilot scale gasifiers using liquors containing sulfur, both at low and high temperatures the lack of a commercial unit is an impediment to the implementation of the MSSAQ technology. The implementation of a commercial unit needs to be facilated before the benefits of
