Review and model-based analysis of factors influencing soil carbon sequestration beneath switchgrass (Panicum virgatum)  

SciTech Connect

Abstract. A simple, multi-compartment model was developed to predict soil carbon sequestration beneath switchgrass (Panicum virgatum) plantations in the southeastern United States. Soil carbon sequestration is an important component of sustainable switchgrass production for bioenergy because soil organic matter promotes water retention, nutrient supply, and soil properties that minimize erosion. A literature review was included for the purpose of model parameterization and five model-based experiments were conducted to predict how changes in environment (temperature) or crop management (cultivar, fertilization, and harvest efficiency) might affect soil carbon storage and nitrogen losses. Predictions of soil carbon sequestration were most sensitive to changes in annual biomass production, the ratio of belowground to aboveground biomass production, and temperature. Predictions of ecosystem nitrogen loss were most sensitive to changes in annual biomass production, the soil C/N ratio, and nitrogen remobilization efficiency (i.e., nitrogen cycling within the plant). Model-based experiments indicated that 1) soil carbon sequestration can be highly site specific depending on initial soil carbon stocks, temperature, and the amount of annual nitrogen fertilization, 2) response curves describing switchgrass yield as a function of annual nitrogen fertilization were important to model predictions, 3) plant improvements leading to greater belowground partitioning of biomass could increase soil carbon sequestration, 4) improvements in harvest efficiency have no indicated effects on soil carbon and nitrogen, but improve cumulative biomass yield, and 5) plant improvements that reduce organic matter decomposition rates could also increase soil carbon sequestration, even though the latter may not be consistent with desired improvements in plant tissue chemistry to maximize yields of cellulosic ethanol.

KGaA, Weinheim 1 Introduction Switchgrass (Panicum virgatum L.) is a warm-sea- son perennial grass that is a major component of the prairies of North America. It is grown in mono- culture for hay, grazing, and erosion control [1]. Also, switchgrass has a high biomass production potential as a feedstock for biofuel production [2, 3]. Genetic manipulation of the growth and devel- opment of switchgrass is needed for better cellu- losic ethanol production, especially to improve cel- lulose-to-lignin ratios. The latest genomic and biotechnology tools can be used for the production of designer plants for this purpose, which is immi- nently feasible. Several genes can make significant

Large-scale production, harvest and logistics of switchgrass (Panicum virgatum L.) - current technology and envisioning a mature technology  

SciTech Connect

Switchgrass (Panicum virgatum L.) is a promising cellulosic biomass feedstock for biorefineries and biofuel production. This paper reviews current and future potential technologies for production, harvest, storage, and transportation of switchgrass. Our analysis indicates that for a yield of 10 Mg ha 1, the current cost of producing switchgrass (after establishment) is about $41.50 Mg 1. The costs may be reduced to about half this if the yield is increased to 30 Mg ha 1 through genetic improvement, intensive crop management, and/or optimized inputs. At a yield of 10 Mg ha 1, we estimate that harvesting costs range from $23.72 Mg 1 for current baling technology to less than $16 Mg 1 when using a loafing collection system. At yields of 20 and 30 Mg ha 1 with an improved loafing system, harvesting costs are even lower at $12.75 Mg 1 and $9.59 Mg 1, respectively. Transport costs vary depending upon yield and fraction of land under switchgrass, bulk density of biomass, and total annual demand of a biorefinery. For a 2000 Mg d 1 plant and an annual yield of 10 Mg ha 1, the transport cost is an estimated $15.42 Mg 1, assuming 25% of the land is under switchgrass production. Total delivered cost of switchgrass using current baling technology is $80.64 Mg 1, requiring an energy input of 8.5% of the feedstock higher heating value (HHV). With mature technology, for example, a large, loaf collection system, the total delivered cost is reduced to about $71.16 Mg 1 with 7.8% of the feedstock HHV required as input. Further cost reduction can be achieved by combining mature technology with increased crop productivity. Delivered cost and energy input do not vary significantly as biorefinery capacity increases from 2000 Mg d 1 to 5000 Mg d 1 because the cost of increased distance to access a larger volume feedstock offsets the gains in increased biorefinery capacity. This paper outlines possible scenarios for the expansion of switchgrass handling to 30 Tg (million Mg) in 2015 and 100 Tg in 2030 based on predicted growth of the biorefinery industry in the USA. The value of switchgrass collection operations is estimated at more than $0.6 billion in 2015 and more than $2.1 billion in 2030. The estimated value of post harvest operations is $0.6 $2.0 billion in 2015, and $2.0 $6.5 billion in 2030, depending on the degree of preprocessing. The need for power equipment (tractors) will increase from 100 MW in 2015 to 666 MW in 2030, with corresponding annual values of $150 and $520 million, respectively. 2009 Society of Chemical Industry and John Wiley & Sons, Ltd

Development of In Vitro Systems for Switchgrass (Panicum virgatum) - Final Report for 1992 to 2002  

SciTech Connect

Our project began on July 1, 1992, with the objective of developing systems that could be used in biotechnological approaches to switchgrass improvement. Within six months after initiation of the project, we had worked out protocols in which plants could be regenerated from callus cultures through both organogenesis and somatic embryogenesis. Documentation for both modes of regeneration was provided in our progress reports and in publications. One thousand regenerated plants were established in the field during the first year. We found that Alamo (lowland type) was much more amenable to in vitro culture, and plants could be regenerated much more easily than from Cave-in-Rock (upland type). During the first three years of the project, we studied the influence of genotype, culture medium components, explant type, etc., on regeneration. As mentioned, we found that the lowland cultivars Alamo and Kanlow were much easier to regenerate than upland cultivars, such as Trailblazer, Blackwell, and Cave-in-Rock. For callus induction, we initially used mature caryopses, young leaf tissue, and portions of seedlings. We were successful in inducing callus and regenerating plants from all explants. Two other systems developed during the 4th to 6th year period of the project included multiple shoot formation initiated from germinated seedlings and regenerable suspension cultures. The latter were initiated from embryogenic calluses produced from in vitro developed inflorescences. An important factor for producing multiple shoots was the presence of thidiazuron in the medium. The shoots could be easily rooted and numerous plantlets produced. The last 3 to 4 years of the project focused on anther and microspore culture experiments to produce haploid plants and on genetic transformation. Although thousands of putative haploid plants were produced from a few anthers, they were very weak and difficult to keep alive. Chromosome counts revealed the gametic number in cells where it was possible to count chromosomes. The isolated microspore culture experiments were not successful.

Open Open Access Advances in biotechnology and genomics of switchgrass Madhugiri Nageswara-Rao 1,2* , Jaya R Soneji 2 , Charles Kwit 1 and C Neal Stewart Jr 1,3* Abstract Switchgrass (Panicum virgatum L.) is a C 4 perennial warm season grass indigenous to the North American tallgrass prairie. A number of its natural and agronomic traits, including adaptation to a wide geographical distribution, low nutrient requirements and production costs, high water use efficiency, high biomass potential, ease of harvesting, and potential for carbon storage, make it an attractive dedicated biomass crop for biofuel production. We believe that genetic improvements using biotechnology will be important to realize the potential of the biomass and biofuel-related uses of switchgrass.

Simulating Potential Switchgrass Production in the United States  

SciTech Connect

Using results from field trials of switchgrass (Panicum virgatum L.) in the United States, the EPIC (Environmental Policy Integrated Climate) process-level agroecosystem model was calibrated, validated, and applied to simulate potential productivity of switchgrass for use as a biofuel feedstock. The model was calibrated with a regional study of 10-yr switchgrass field trials and subsequently tested against a separate compiled dataset of field trials from across the eastern half of the country. An application of the model in a national database using 8-digit watersheds as the primary modeling unit produces 30-yr average switchgrass yield estimates that can be aggregated to 18 major watersheds. The model projects average annual switchgrass productivity of greater than 7 Mg ha-1 in the Upper Mississippi, Lower Mississippi, and Ohio watersheds. The major factors limiting simulated production vary by region; low precipitation is the primary limiting factor across the western half of the country, while moderately acidic soils limit yields on lands east of the Mississippi River. Average projected switchgrass production on all crop land in the continental US is 5.6 Mg ha-1. At this level of productivity, 28.6 million hectares of crop land would be required to produce the 16 billion gallons of cellulosic ethanol called for by 2022 in the 2007 Energy Independence and Security Act. The model described here can be applied as a tool to inform the land-use and environmental consequences of switchgrass production.

Changes in soil carbon and nitrogen associated with switchgrass production  

E-Print Network (OSTI)

Greater knowledge of the short- and long-term effects of biomass production practices on soil biological and chemical properties is needed to determine influences on sustainable land management. Soil samples under switchgrass (Panicum virgatum L.), other forage grasses, cultivated crops, and forest were collected seasonally at six locations. Soil organic C (SOC), total N, soil microbial biomass C (SMBC) and N (SMBN), soil mineralizable C and N, and basal soil respiration (BSR) were in general greatest under long-term coastal bermudagrass [Cynodon dactylon (L.) Pers.] pasture (>40 years), second highest under Alamo switchgrass and kleingrass (Panicum coloratum L.) planted in 1992 and forest, followed by Alamo switchgrass planted in 1997, and was lowest under the cultivated soils. Soil organic C at 0-5 cm was 42-220% greater in soils under Alamo switchgrass planted in 1992 than cultivated soils, except at College Station where SOC values under Alamo planted in 1992 and the cultivated rotation were not significantly different. Although the rotation treatment is cultivated at this location, two high residue crops are used, wheat (Triticum aestivum L.) and sorghum [Sorghum bicolor (L.) Moench.]. Similar trends were noted for total N, SMBC, SMBN, mineralizable C and N, BSR, and the ratio of SMBC/SOC. Insufficient information was collected in this study to determine whether the parameters evaluated for forest and switchgrass were different. In addition to its high yield potential, adaptation to marginal sites and tolerance to water and nutrient limitations, switchgrass appeared to be a competitive crop in terms of land sustainability, resulting in enhanced soil quality characteristics compared to long-term cultivated soils.

Timing Affects Switchgrass Production, Forage Nutritive Value, and Nutrient Removal  

E-Print Network (OSTI)

Switchgrass (Panicum virgatum L.) has potential for both bioenergy and forage. The objectives of this experiment were to: i) determine whether switchgrass could be harvested for greater nutritive value during the vegetative stage relative to early reproductive growth (boot stage); ii) compare biomass yields of switchgrass harvested once versus twice per year for bioenergy; and iii) examine effects of N fertilizer rates on harvest systems. The experiment was a randomized complete block design with a split-plot arrangement of harvest system treatments as main plot (harvest once per year after frost, harvest twice per year first at vegetative or boot stage and regrowth after frost) and nitrogen (N) fertilizer rate as subplots (0, 90, 180, and 270 kg N ha-1). Biomass yield was greatest and nutrient concentrations were least in the one-cut system. For the two-cut system, nutritive values and yields were similar. Total annual biomass increased linearly with N fertilization. Across N rates, CP concentration for the two-cut systems was 50 % greater (71 g kg-1) and ADF and NDF concentrations were 20 % lesser (465 and 856 g kg-1, respectively) than switchgrass in the one-cut system. Switchgrass harvested at vegetative through boot stage and its regrowth could provide forage of acceptable nutritive value to beef cows. However, greater nutrient removal requires appropriate soil fertility evaluation and fertilizer management for sustainable yields.

Why Sequence Switchgrass?  

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

Switchgrass? Switchgrass? A long-standing mission of the DOE has been to develop alternative sources of energy from biomass, and with good reason President George W. Bush specifically mentioned switchgrass as a promising energy crop in his 2006 State of the Union Address. This native grass has many traits that make it well suited for use as an energy feedstock. Yields of switchgrass are high, averaging 7 tons per acre in unirrigated field trials with some lines yielding up to 10 tons per acre. Production costs are low because of the plant's low nutrient use, minimal pesticide requirements, propagation by seed, and perennial growth habit. Switchgrass can be harvested with conventional haying equipment, and its wide adaptability allows it to be grown productively across a large geographic area, including marginal

Soil carbon dynamics beneath switchgrass as indicated by stable isotope analysis  

Science Conference Proceedings (OSTI)

Surface (0--40 cm) soil organic carbon (SOC) dynamics were studied beneath four switchgrass (Panicum virgatum L.) field trails in the southeastern US. Soil organic carbon was partitioned into particulate organic matter (POM) and mineral-associated organic matter (MOM). Most (75--90%) of the SOC at each study site was affiliated with MOM (<0.053 mm). Changes in stable carbon isotope ratios were used to derive carbon inputs to and losses from POM and MOM at each site. Inventories of existing SOC and new C{sub 4}-derived SOC beneath switchgrass decreased with increasing soil depth. Approximately 5 yr after establishment, 19 to 31% of the existing SOC inventories beneath switchgrass had been derived from new C{sub 4}-carbon inputs. Calculated turnover times of POM and MOM ranged from 2.4 to 4.3 yr and 26 to 40 yr, respectively. The turnover time of SOC in the POM fraction increased with decreasing mean annual temperature. A simple, two-compartment model was parameterized to predict the potential for soil carbon sequestration under switchgrass. An example calculation with the model indicated a measurable and verifiable recovery of soil carbon (=12% increase) on degraded lands through one decade of switchgrass production. The potential to sequester carbon through switchgrass cultivation will depend on initial soil carbon inventories, prevailing climate, soil types and site management.

Soil carbon inventories under a bioenergy crop (switchgrass): Measurement limitations  

Science Conference Proceedings (OSTI)

Approximately 5 yr after planting, coarse root carbon (C) and soil organic C (SOC) inventories were compared under different types of plant cover at four switchgrass (Panicum virgatum L.) production field trials in the southeastern USA. There was significantly more coarse root C under switchgrass (Alamo variety) and forest cover than tall fescue (Festuca arundinacea Schreb.), corn (Zea mays L.), or native pastures of mixed grasses. Inventories of SOC under switchgrass were not significantly greater than SOC inventories under other plant covers. At some locations the statistical power associated with ANOVA of SOC inventories was low, which raised questions about whether differences in SOC could be detected statistically. A minimum detectable difference (MDD) for SOC inventories was calculated. The MDD is the smallest detectable difference between treatment means once the variation, significance level, statistical power, and sample size are specified. The analysis indicated that a difference of {approx}50 mg SOC/cm{sup 2} or 5 Mg SOC/ha, which is {approx}10 to 15% of existing SOC, could be detected with reasonable sample sizes and good statistical power. The smallest difference in SOC inventories that can be detected, and only with exceedingly large sample sizes, is {approx}2 to 3%. These measurement limitations have implications for monitoring and verification of proposals to ameliorate increasing global atmospheric CO{sub 2} concentrations by sequestering C in soils.

Switchgrass (Panicum virgatum) is a perennial, warm-season grass that has been identified as a potential biofuel feedstock over a large part of North America.Weexamined above- and belowground responses to nitrogen fertilization in Alamo switchgrass grown in West Tennessee, USA. The fertilizer study included a spring and fall sampling of 5-year old switchgrass grown under annual applications of 0, 67, and 202 kgNha?1 (as ammonium nitrate). Fertilization changed switchgrass biomass allocation as indicated by root:shoot ratios. End-of-growing season root:shoot ratios (meanSE) declined significantly (P?0.05) at the highest fertilizer nitrogen treatment (2.160.08, 2.020.18, and 0.880.14, respectively, at 0, 67, and 202 kgNha?1). Fertilization also significantly increased above- and belowground nitrogen concentrations and decreased plant C:N ratios. Data are presented for coarse live roots, fine live roots, coarse dead roots, fine dead roots, and rhizomes. At the end of the growing season, there was more carbon and nitrogen stored in belowground biomass than aboveground biomass. Fertilization impacted switchgrass tissue chemistry and biomass

SANS Study of Cellulose Extracted from Switchgrass  

SciTech Connect

AbstractLignocellulosic biomass, an abundant renewable natural resource, has the potential to play a major role in generation of renewable biofuels through its conversion to bio-ethanol. Unfortunately, it is a complex biological composite material that shows significant recalcitrance making it a cost-ineffective feedstock for bioethanol production. Small-angle neutron scattering (SANS) was employed to probe the multi-scale structure of cellulosic materials. Cellulose was extracted from milled native switchgrass and switchgrass that had undergone the dilute acid pretreatment method to disrupt the lignocellulose structure. The high-Q structural feature (Q > 0.07 -1) can be assigned to cellulose fibrils based on comparison with the switchgrass purified by solvent extraction of native and dilute acid pretreated and a commercial preparation of microcrystalline cellulose. Dilute acid pretreatment results in an increase in the smallest structural size, a decrease in the interconnectivity of the fibrils; and no change in the smooth domain boundaries at length scales larger than 1000 .

Targeted Discovery of Glycoside Hydrolases from a Switchgrass-Adapted Compost Community  

Science Conference Proceedings (OSTI)

Development of cellulosic biofuels from non-food crops is currently an area of intense research interest. Tailoring depolymerizing enzymes to particular feedstocks and pretreatment conditions is one promising avenue of research in this area. Here we added a green-waste compost inoculum to switchgrass (Panicum virgatum) and simulated thermophilic composting in a bioreactor to select for a switchgrass-adapted community and to facilitate targeted discovery of glycoside hydrolases. Smallsubunit (SSU) rRNA-based community profiles revealed that the microbial community changed dramatically between the initial and switchgrass-adapted compost (SAC) with some bacterial populations being enriched over 20-fold. We obtained 225 Mbp of 454-titanium pyrosequence data from the SAC community and conservatively identified 800 genes encoding glycoside hydrolase domains that were biased toward depolymerizing grass cell wall components. Of these, ,10percent were putative cellulasesmostly belonging to families GH5 and GH9. We synthesized two SAC GH9 genes with codon optimization for heterologous expression in Escherichia coli and observed activity for one on carboxymethyl cellulose. The active GH9 enzyme has a temperature optimum of 50uC and pH range of 5.5 to 8 consistent with the composting conditions applied. We demonstrate that microbial communities adapt to switchgrass decomposition using simulated composting condition and that full-length genes can be identified from complex metagenomic sequence data, synthesized and expressed resulting in active enzyme.

Multimetric spatial optimization of switchgrass plantings across a watershed  

SciTech Connect

The increasing demand for bioenergy crops presents our society with the opportunity to design more sustainable landscapes. We have created a Biomass Location for Optimal Sustainability Model (BLOSM) to test the hypothesis that landscape design of cellulosic bioenergy crop plantings may simultaneously improve water quality (i.e., decrease concentrations of sediment, total phosphorus, and total nitrogen) and increase profits for farmer-producers while achieving a feedstock-production goal. BLOSM was run using six scenarios to identify switchgrass (Panicum virgatum) planting locations that might supply a commercial-scale biorefinery planned for the Lower Little Tennessee (LLT) watershed. Each scenario sought to achieve different sustainability goals: improving water quality through reduced nitrogen, phosphorus, or sediment concentrations; maximizing profit; a balance of these conditions; or a balance of these conditions with the additional constraint of converting no more than 25% of agricultural land. Scenario results were compared to a baseline case of no land-use conversion. BLOSM results indicate that a combined economic and environmental optimization approach can achieve multiple objectives simultaneously when a small proportion (1.3%) of the LLT watershed is planted with perennial switchgrass. The multimetric optimization approach described here can be used as a research tool to consider bioenergy plantings for other feedstocks, sustainability criteria, and regions.

Soil carbon inventories under a bioenergy crop (switchgrass): measurement limitations  

Science Conference Proceedings (OSTI)

Approximately 5 yr after planting, coarse root (>2 mm) carbon (C) and soil organic C (SOC) inventories (0-40 cm deep) were compared under different types of plant cover at four switchgrass (Panicum virgatum L.) production field trials in the southeastern USA. There was significantly (p {le} 0.05) more coarse root C under switchgrass (Alamo variety) and forest cover than under tall fescue (Festuca arundinacea Schreb.), corn (Zea mays L.), or native pastures of mixed grasses. Inventories of SOC under switchgrass were not significantly greater than SOC inventories under other plant covers. At some locations the statistical power associated with ANOVA of SOC inventories was low, which raised questions about whether differences in SOC could be detected statistically. A minimum detectable difference (MDD) for SOC inventories was calculated. The MDD is the smallest detectable difference between treatment means once the variation, significance level, statistical power, and sample size are specified. The analysis indicated that a difference of {approx}50 mg SOC/cm{sup 2} or 5 Mg SOC/ha, which is {approx}10 to 15% of existing SOC, could be detected with reasonable sample sizes (n = 16) and good statistical power (1-{beta} = 0.90). The smallest difference in SOC inventories that can be detected, and only with exceedingly large sample sizes (n > 100), is {approx}2 to 3% ({approx}10 mg SOC/cm{sup 2} or 1 Mg SOC/ha). These measurement limitations have implications for monitoring and verification of proposals to ameliorate increasing global atmospheric CO{sub 2} concentrations by sequestering C in soils.

Switchgrass biomass and chemical composition for biofuel in eastern Canada  

SciTech Connect

Switchgrass (Panicum virgatum L.) is one of several warm-season grasses that have been identified as potential biomass crops in North America. A two-year field study was conducted, on a free-draining sandy clay loam (St. Bernard, Typic Hapludalf), to characterize the growth and evaluate changes in biomass accumulation and composition of switchgrass at Montreal, QC. Three cultivars, Cave-in-Rock, Pathfinder, and Sunburst, were grown in solid stands in a randomized complete block design. Canopy height, dry matter (DM) accumulation and chemical composition were monitored biweekly throughout the growing season. Average maximum canopy heights were 192.5 cm for Cave-in-Rock, 169.9 for Pathfinder, and 177.8 for Sunburst. The respective end-of-season DM yields were 12.2, 11.5, and 10.6 Mg/ha. Biomass production among cultivars appeared to be related to time of maturation. Nitrogen concentration of DM decreased curvilinearly from 25 g/kg at the beginning of the season to 5 g/kg DM at season's end. Both acid-detergent fiber (ADF) and neutral-detergent fiber (NDF) concentrations increased to a maximum early in the season, after which no changes were detected. The average maximum values of ADF and NDF were, respectively, 647.6 and 849.0 g/kg DM for Cave-in-Rock, 669.1 and 865.2 for Pathfinder, and 661.8 and 860.9 for Sunburst. Changes in canopy height, DM accumulation, and chemical composition could all be described by predictive regression equations. These results indicate that switchgrass has potential as a biomass crop in a short-season environment.

Developing Switchgrass as a Bioenergy Crop  

DOE Green Energy (OSTI)

The utilization of energy crops produced on American farms as a source of renewable fuels is a concept with great relevance to current ecological and economic issues at both national and global scales. Development of a significant national capacity to utilize perennial forage crops, such as switchgrass (Panicum virgatum, L.) as biofuels could benefit our agricultural economy by providing an important new source of income for farmers. In addition energy production from perennial cropping systems, which are compatible with conventional fining practices, would help reduce degradation of agricultural soils, lower national dependence on foreign oil supplies, and reduce emissions of greenhouse gases and toxic pollutants to the atmosphere (McLaughlin 1998). Interestingly, on-farm energy production is a very old concept, extending back to 19th century America when both transpofiation and work on the farm were powered by approximately 27 million draft animals and fueled by 34 million hectares of grasslands (Vogel 1996). Today a new form of energy production is envisioned for some of this same acreage. The method of energy production is exactly the same - solar energy captured in photosynthesis, but the subsequent modes of energy conversion are vastly different, leading to the production of electricity, transportation fuels, and chemicals from the renewable feedstocks. While energy prices in the United States are among the cheapest in the world, the issues of high dependency on imported oil, the uncertainties of maintaining stable supplies of imported oil from finite reserves, and the environmental costs associated with mining, processing, and combusting fossil fuels have been important drivers in the search for cleaner burning fuels that can be produced and renewed from the landscape. At present biomass and bioenergy combine provide only about 4% of the total primary energy used in the U.S. (Overend 1997). By contrast, imported oil accounts for approximately 44% of the foreign trade deficit in the U.S. and about 45% of the total annual U.S. oil consumption of 34 quads (1 quad = 1015 Btu, Lynd et al. 1991). The 22 quads of oil consumed by transportation represents approximately 25% of all energy use in the US and excedes total oil imports to the US by about 50%. This oil has environmental and social costs, which go well beyond the purchase price of around $15 per barrel. Renewable energy from biomass has the potential to reduce dependency on fossil fhels, though not to totally replace them. Realizing this potential will require the simultaneous development of high yielding biomass production systems and bioconversion technologies that efficiently convert biomass energy into the forms of energy and chemicals usable by industry. The endpoint criterion for success is economic gain for both agricultural and industrial sectors at reduced environmental cost and reduced political risk. This paper reviews progress made in a program of research aimed at evaluating and developing a perennial forage crop, switchgrass as a regional bioenergy crop. We will highlight here aspects of research progress that most closely relate to the issues that will determine when and how extensively switchgrass is used in commercial bioenergy production.

Down-regulation of the Caffeic acid O-methyltransferase Gene in Switchgrass Reveals a Novel Monolignol Analog  

SciTech Connect

Down-regulation of the caffeic acid 3-O-methyltransferase (COMT) gene in the lignin biosynthetic pathway of switchgrass (Panicum virgatum) resulted in cell walls of transgenic plants releasing more constituent sugars after pretreatment by dilute acid and treatment with glycosyl hydrolases from an added enzyme preparation and from Clostridium thermocellum. Fermentation of both wild-type and transgenic switchgrass after milder hot water pretreatment with no water washing showed that only the transgenic switchgrass inhibited C. thermocellum. Gas chromatography-mass spectrometry-based metabolomics were undertaken on cell wall aqueous extracts to determine the nature of the microbial inhibitors, confirming the increased concentration of a number of phenolic acids and aldehydes that are known inhibitors of fermentation. Metabolomic analyses of the transgenic biomass additionally revealed the presence of a novel monolignol-like metabolite, identified as trans-3, 4-dimethoxy-5-hydroxycinnamyl alcohol (iso-sinapyl alcohol) in both non-pretreated, as well as hot water pretreated samples. Although there was no indication that iso-sinapyl alcohol was integrated into the cell wall, diversion of substrates from sinapyl alcohol to free iso-sinapyl alcohol, its glucoside, and associated upstream lignin pathway changes, including increased phenolic aldehydes and acids, are associated with more facile cell wall deconstruction, and to the observed inhibitory effect on microbial growth.

Global Simulation of Bioenergy Crop Productivity: Analytical framework and Case Study for Switchgrass  

SciTech Connect

Contemporary global assessments of the deployment potential and sustainability aspects of biofuel crops lack quantitative details. This paper describes an analytical framework capable of meeting the challenges associated with global scale agro-ecosystem modeling. We designed a modeling platform for bioenergy crops, consisting of five major components: (i) standardized global natural resources and management data sets, (ii) global simulation unit and management scenarios, (iii) model calibration and validation, (iv) high-performance computing (HPC) modeling, and (v) simulation output processing and analysis. A case study with the HPC- Environmental Policy Integrated Climate model (HPC-EPIC) to simulate a perennial bioenergy crop, switchgrass (Panicum virgatum L.) and global biomass feedstock analysis on grassland demonstrates the application of this platform. The results illustrate biomass feedstock variability of switchgrass and provide insights on how the modeling platform can be expanded to better assess sustainable production criteria and other biomass crops. Feedstock potentials on global grasslands and within different countries are also shown. Future efforts involve developing databases of productivity, implementing global simulations for other bioenergy crops (e.g. miscanthus, energycane and agave), and assessing environmental impacts under various management regimes. We anticipated this platform will provide an exemplary tool and assessment data for international communities to conduct global analysis of biofuel biomass feedstocks and sustainability.

Global Simulation of Bioenergy Crop Productivity: Analytical Framework and Case Study for Switchgrass  

SciTech Connect

A global energy crop productivity model that provides geospatially explicit quantitative details on biomass potential and factors affecting sustainability would be useful, but does not exist now. This study describes a modeling platform capable of meeting many challenges associated with global-scale agro-ecosystem modeling. We designed an analytical framework for bioenergy crops consisting of six major components: (i) standardized natural resources datasets, (ii) global field-trial data and crop management practices, (iii) simulation units and management scenarios, (iv) model calibration and validation, (v) high-performance computing (HPC) simulation, and (vi) simulation output processing and analysis. The HPC-Environmental Policy Integrated Climate (HPC-EPIC) model simulated a perennial bioenergy crop, switchgrass (Panicum virgatum L.), estimating feedstock production potentials and effects across the globe. This modeling platform can assess soil C sequestration, net greenhouse gas (GHG) emissions, nonpoint source pollution (e.g., nutrient and pesticide loss), and energy exchange with the atmosphere. It can be expanded to include additional bioenergy crops (e.g., miscanthus, energy cane, and agave) and food crops under different management scenarios. The platform and switchgrass field-trial dataset are available to support global analysis of biomass feedstock production potential and corresponding metrics of sustainability.

Biomass production by fescue and switchgrass alone and in mixed swards with legumes. Final project report  

SciTech Connect

In assessing the role of biomass in alleviating potential global warming, the absence of information on the sustainability of biomass production on soils of limited agricultural potential is cited as a major constraint to the assessment of the role of biomass. Research on the sustainability of yields, recycling of nutrients, and emphasis on reduced inputs of agricultural chemicals in the production of biomass are among the critical research needs to clarify optimum cropping practice in biomass production. Two field experiments were conducted between 1989 and 1993. One study evaluated biomass production and composition of switchgrass (Panicum virgatum L.) grown alone and with bigflower vetch (Vicia grandiflora L.) and the other assessed biomass productivity and composition of tall fescue (Festuca arundinacea Schreb.) grown alone and with perennial legumes. Switchgrass received 0, 75 or 150 kg ha{sup {minus}1} of N annually as NH{sub 4}NO{sub 3} or was interseeded with vetch. Tall fescue received 0, 75, 150 or 225 kg ha{sup {minus}1} of N annually or was interseeded with alfalfa (Medicago L.) or birdsfoot trefoil (Lotus corniculatus L.). It is hoped that production systems can be designed to produce high yields of biomass with minimal inputs of fertilizer N. Achievement of this goal would reduce the potential for movement of NO{sub 3} and other undesirable N forms outside the biomass production system into the environment. In addition, management systems involving legumes could reduce the cost of biomass production.

Switchgrass was gasified in a bubbling fluidized bed reactor rated at 800 kW (2.75 MMBtu/hr) thermal input and operating at atmospheric pressure. A combustible gas with higher heating value varying between 4.2--5.9 MJ/Nm{sup 3} (114--160 Btu/scf) was produced. Carbon conversion was approximately 85%. Difficulties in feeding high moisture switchgrass inhibited smooth reactor operation. Several feed systems for switchgrass were tried with varying degrees of success. The results of gasification trials using switchgrass as fuel are described.

The Chariton Valley Biomass Power Project, sponsored by the Chariton Valley RC&D Inc., a USDA-sponsored rural development organization, the Iowa Department of Natural Resources Energy Bureau (IDNR-EB), and IES Utilities, a major Iowa energy company, is directed at the development of markets for energy crops in southern Iowa. This effort is part of a statewide coalition of public and private interests cooperating to merge Iowa`s agricultural potential and its long-term energy requirements to develop locally sustainable sources of biomass fuel. The four-county Chariton Valley RC&D area (Lucas, Wayne, Appanoose and Monroe counties) is the site of one of eleven NREL/EPRI feasibility studies directed at the potential of biomass power. The focus of renewable energy development in the region has centered around the use of swithgrass (Panicum virgatum, L.). This native Iowa grass is one of the most promising sustainable biomass fuel crops. According to investigations by the U.S. Department of Energy (DOE), switchgrass has the most potential of all the perennial grasses and legumes evaluated for biomass production.

Direct mechanical energy measures of hammer mill comminution of switchgrass, wheat straw, and corn stover and analysis of their particle size distributions  

Science Conference Proceedings (OSTI)

Biomass particle size impacts handling, storage, conversion, and dust control systems. Size reduction mechanical energy was directly measured for switchgrass (Panicum virgatum L.), wheat straw (Triticum aestivum L.), and corn stover (Zea mays L.) in an instrumented hammer mill. Direct energy inputs were determined for hammer mill operating speeds from 2000 to 3600 rpm for 3.2 mm integral classifying screen and mass input rate of 2.5 kg/min with 90 - and 30 -hammers. Overall accuracy of specific energy measurement was calculated as 0.072 MJ/Mg. Particle size distributions created by hammer mill were determined for mill operating factors using ISO sieve sizes from 4.75 to 0.02 mm in conjunction with Ro-Tap sieve analyzer. A wide range of analytical descriptors were examined to mathematically represent the range of particle sizes in the distributions. Total specific energy (MJ/Mg) was defined as size reduction energy to operate the hammer mill plus that imparted to biomass. Effective specific energy was defined as energy imparted to biomass. Total specific energy for switchgrass, wheat straw, and corn stover grinding increased by 37, 30, and 45% from 114.4, 125.1, and 103.7 MJ/Mg, respectively, with an increase in hammer mill speed from 2000 to 3600 rpm for 90 -hammers. Corresponding total specific energy per unit size reduction was 14.9, 19.7, and 13.5 MJ/Mg mm, respectively. Effective specific energy of 90 -hammers decreased marginally for switchgrass and considerably for wheat straw and it increased for corn stover with an increase in speed from 2000 to 3600 rpm. However, effective specific energy increased with speed to a certain extent and then decreased for 30 -hammers. Rosin Rammler equation fitted the size distribution data with R2 > 0.995. Mass relative span was greater than 1, which indicated a wide distribution of particle sizes. Hammer milling of switchgrass, wheat straw, and corn stover with 3.2 mm screen resulted in well-graded fine-skewed mesokurtic particles. Uniformity coefficient was corn stover, which indicated a moderate assortment of particles. Size-related parameters, namely, geometric mean diameter, Rosin Rammler size parameter, median diameter, and effective size had strong correlation among themselves and good negative correlation with speed. Distribution-related parameters, namely, Rosin Rammler distribution parameter, mass relative span, inclusive graphic skewness, graphic kurtosis, uniformity index, uniformity coefficient, coefficient of gradation and distribution geometric standard deviation had strong correlation among themselves and a weak correlation with mill speed. Results of this extensive analysis of specific energy and particle sizes can be applied to selection of hammer mill operating factors to produce a particular size of switchgrass, wheat straw, and corn stover grind, and will serve as a guide for relations among the energy and various analytic descriptors of biomass particle distributions.

Review Switchgrass- practical issues in developing a fuel crop CAB Reviews 2012 7, No. 037  

E-Print Network (OSTI)

The biomass-based energy sector will play an important role in our drive towards renewable energy. Switchgrass has been identified as one of the candidate-dedicated energy crops in the USA because of its various desirable traits. However, many challenges still exist in ensuring a commercially viable switchgrass crop that is sustainable and techno-economically feasible. This article reviews the existing literature to highlight those challenges and potential solutions and recommendations to address those in the future. Various stages in the switchgrass-based biofuel system, namely crop production, provision and logistics, and conversion, are analysed. For each of these stages, the important challenges as reported in the literature are mentioned, and research gaps are identified. The systems-level issues as well as the challenges associated with the practical implementation of switchgrass production are also highlighted. The review illustrates that although switchgrass is a viable biofuel feedstock, considerable progress is necessary to achieve large-scale practical success.

Flowability parameters for chopped switchgrass, wheat straw and corn stover  

Science Conference Proceedings (OSTI)

A direct shear cell to measure the shear strength and flow properties of chopped switchgrass, wheat straw, and corn stover was designed, fabricated, and tested. Yield loci (r2=0.99) determined at pre-consolidation pressures of 3.80 kPa and 5.02 kPa indicated that chopped biomass followed Mohr-Coulomb failure. Normal stress significantly affected the displacement required for shear failure, as well as the friction coefficient values for all three chopped biomass types. Displacement at shear failure ranged from 30 to 80 mm, and depended on pre-consolidation pressure, normal stress, and particle size. Friction coefficient was inversely related to normal stress, and was highest for chopped corn stover. Also, chopped corn stover exhibited the highest angle of internal friction, unconfined yield strength, major consolidation strength, and cohesive strength, all of which indicated increased challenges in handling chopped corn stover. The measured angle of internal friction and cohesive strength indicated that chopped biomass cannot be handled by gravity alone. The measured angle of internal friction and cohesive strength were 43 and 0.75 kPa for chopped switchgrass; 44 and 0.49 kPa for chopped wheat straw; and 48 and 0.82 kPa for chopped corn stover. Unconfined yield strength and major consolidation strength used for characterization of bulk flow materials and design of hopper dimensions were 3.4 and 10.4 kPa for chopped switchgrass; 2.3 and 9.6 kPa for chopped wheat straw and 4.2 and 11.8 kPa for chopped corn stover. These results are useful for development of efficient handling, storage, and transportation systems for biomass in biorefineries.

Breeding and Selection of New Switchgrass Varieties for Increased Biomass Production  

DOE Green Energy (OSTI)

Switchgrass breeding and genetics research was conducted from 1992-2002 at the Oklahoma State University as part of the national DOE-Bioenergy Feedstock Development Program (BFDP) effort to develop the species as a bioenergy feedstock crop. The fundamental objective of the program was to implement and conduct a breeding program to increase biomass yield capability in switchgrass and develop cultivars for the central and southern United States. Supporting research objectives included: (1) switchgrass germplasm collection, characterization, and enhancement; (2) elucidation of cytogenetic and breeding behavior; and (3) identification of best breeding procedures.

Exploring Potential U.S. Switchgrass Production for Lignocellulosic Ethanol  

Science Conference Proceedings (OSTI)

In response to concerns about oil dependency and the contributions of fossil fuel use to climatic change, the U.S. Department of Energy has begun a research initiative to make 20% of motor fuels biofuel based in 10 years, and make 30% of fuels bio-based by 2030. Fundamental to this objective is developing an understanding of feedstock dynamics of crops suitable for cellulosic ethanol production. This report focuses on switchgrass, reviewing the existing literature from field trials across the United States, and compiling it for the first time into a single database. Data available from the literature included cultivar and crop management information, and location of the field trial. For each location we determined latitude and longitude, and used this information to add temperature and precipitation records from the nearest weather station. Within this broad database we were able to identify the major sources of variation in biomass yield, and to characterize yield as a function of some of the more influential factors, e.g., stand age, ecotype, precipitation and temperature in the year of harvest, site latitude, and fertilization regime. We then used a modeling approach, based chiefly on climatic factors and ecotype, to predict potential yields for a given temperature and weather pattern (based on 95th percentile response curves), assuming the choice of optimal cultivars and harvest schedules. For upland ecotype varieties, potential yields were as high as 18 to 20 Mg/ha, given ideal growing conditions, whereas yields in lowland ecotype varieties could reach 23 to 27 Mg/ha. The predictive equations were used to produce maps of potential yield across the continental United States, based on precipitation and temperature in the long term climate record, using the Parameter-elevation Regressions on Independent Slopes Model (PRISM) in a Geographic Information System (GIS). Potential yields calculated via this characterization were subsequently compared to the Oak Ridge Energy Crop County Level data base (ORECCL), which was created at Oak Ridge National Laboratory (Graham et al. 1996) to predict biofuel crop yields at the county level within a limited geographic area. Mapped output using the model was relatively consistent with known switchgrass distribution. It correctly showed higher yields for lowland switchgrass when compared with upland varieties at most locations. Projections for the most northern parts of the range suggest comparable yields for the two ecotypes, but inadequate data for lowland ecotypes grown at high latitudes make it difficult to fully assess this projection. The final model is a predictor of optimal yields for a given climate scenario, but does not attempt to identify or account for other limiting or interacting factors. The statistical model is nevertheless an improvement over historical efforts, in that it is based on quantifiable climatic differences, and it can be used to extrapolate beyond the historic range of switchgrass. Additional refinement of the current statistical model, or the use of different empirical or process-based models, might improve the prediction of switchgrass yields with respect to climate and interactions with cultivar and management practices, assisting growers in choosing high-yielding cultivars within the context of local environmental growing conditions.

Genetic manipulation of lignin reduces recalcitrance and improves biomass ethanol production from switchgrass  

Science Conference Proceedings (OSTI)

Switchgrass is a leading dedicated bioenergy feedstock because it is a native, high yielding, perennial prairie grass with broad cultivation range and low agronomic input requirements. Biomass conversion research has developed pilot scale processes for production of ethanol and other alcohols but they remain costly primarily due to the intrinsic recalcitrance of biomass. We show here that switchgrass genetic modification can produce normal plants that have reduced thermochemical and enzymatic recalcitrance. Downregulation of the switchgrass caffeic O-methyltransferase gene decreases lignin content modestly, reduces the syringyl to guaiacyl lignin monomer ratio and increases the ethanol yield by up to a third using conventional biomass fermentation processes. The downregulated lines have wild-type biomass yields but require reduced pretreatment severity and 300-400% lower cellulase dosages for equivalent product yields significantly lowering processing costs. Alternately, our modified transgenic switchgrass lines should yield significantly more fermentation chemicals per hectare under identical process conditions.

Bulk density and compaction behavior of knife mill chopped switchgrass,wheat straw, and corn stover  

SciTech Connect

Bulk density of comminuted biomass significantly increased by vibration during handling and transportation, and by normal pressure during storage. Compaction characteristics affecting the bulk density of switchgrass, wheat straw, and corn stover chopped in a knife mill at different operating conditions and using four different classifying screens were studied. Mean loose-filled bulk densities were 67.5 18.4 kg/m3 for switchgrass, 36.1 8.6 kg/m3 for wheat straw, and 52.1 10.8 kg/m3 for corn stover. Mean tapped bulk densities were 81.8 26.2 kg/m3 for switchgrass, 42.8 11.7 kg/m3 for wheat straw, and 58.9 13.4 kg/m3 for corn stover. Percentage changes in compressibility due to variation in particle size obtained from a knife mill ranged from 64.3 to 173.6 for chopped switchgrass, 22.2 51.5 for chopped wheat straw and 42.1 117.7 for chopped corn stover within the tested consolidation pressure range of 5 120 kPa. Pressure and volume relationship of chopped biomass during compression with application of normal pressure can be characterized by the Walker model and Kawakita and Ludde model. Parameter of Walker model was correlated to the compressibility with Pearson correlation coefficient greater than 0.9. Relationship between volume reduction in chopped biomass with respect to number of tappings studied using Sone s model indicated that infinite compressibility was highest for chopped switchgrass followed by chopped wheat straw and corn stover. Degree of difficulty in packing measured using the parameters of Sone s model indicated that the chopped wheat straw particles compacted very rapidly by tapping compared to chopped switchgrass and corn stover. These results are very useful for solving obstacles in handling bulk biomass supply logistics issues for a biorefinery.

Summary of Chariton Valley Switchgrass Co-Fire Testing at the Ottumwa Generating Station in Chillicothe, Iowa: Milestone Completion Report  

DOE Green Energy (OSTI)

Results of the switchgrass co-firing tests conducted at the Ottumwa Generating Station in Chillicothe, Iowa as part of the Chariton Valley Biomass Project. After several years of planning, the Chariton Valley Biomass Project successfully completed two months of switchgrass co-fire testing at the Ottumwa Generating Station (OGS) in Chillicothe, Iowa. From November 30, 2000, through January 25, 2001, the switchgrass team co-fired 1,269 tons (1,151 tonnes) of switchgrass at rates up to 16.8 tons/h (15.2 tonne/h), representing about 3% heat input to the 725-MW power plant. Stack testing was completed when co-firing switchgrass and when burning only coal. Fuel and ash samples were collected for analysis, and boiler performance and emissions data were collected. Numerous improvements were made to the feed-handling equipment during testing. The co-fire testing was completed with no environmental incidents, no injuries to personnel, and no loss in electricity output from OGS. The goals of the this--the first of three rounds of co-fire tests--were: to identify the effects of co-firing on boiler performance, to measure any changes in emissions during co-firing, and to gather information to improve the design of the switchgrass handling equipment. All three of these goals were met. The design target for the switchgrass handling system was 12.5 ton/h (11.3 tonne/h), which we exceeded after a redesign of the secondary grinder in our system. We had hoped to burn over 3,000 tons (2,722 tonnes) of switchgrass during this first round of testing, but because of poor equipment performance in December, we were unable to meet this target before the planned boiler shutdown in January. There were, however, several days in January when we burned more than 100 tons (91 tonnes) of switchgrass.

Ethanol production using corn, switchgrass, and wood; Biodiesel production using soybean and sunflower  

E-Print Network (OSTI)

Energy outputs from ethanol produced using corn, switchgrass, and wood biomass were each less than the respective fossil energy inputs. The same was true for producing biodiesel using soybeans and sunflower, however, the energy cost for producing soybean biodiesel was only slightly negative compared with ethanol production. Findings in terms of energy outputs compared with the energy inputs were: Ethanol production using corn grain required 29% more fossil energy than the ethanol fuel produced. Ethanol production using switchgrass required 50 % more fossil energy than the ethanol fuel produced. Ethanol production using wood biomass required 57 % more fossil energy than the ethanol fuel produced. Biodiesel production using soybean required 27 % more fossil energy than the biodiesel fuel produced (Note, the energy yield from soy oil per hectare is far lower than the ethanol yield from corn). Biodiesel production using sunflower required 118 % more fossil energy than the biodiesel fuel produced.

Switchgrass selection as a "model" bioenergy crop: A history of the process  

Science Conference Proceedings (OSTI)

A review of several publications of the Oak Ridge National Laboratory's Biofuels Feedstock Development Program and final reports from the herbaceous crop screening trials show that technology, environmental, and funding issues influenced the decision to focus on a single herbaceous model crop species. Screening trials funded by the U.S. Department of Energy in the late 1980s to early 1990s assessed thirty-four herbaceous species on a wide range of soil types at thirty-one different sites spread over seven states in crop producing regions of the U.S. Several species, including sorghums, reed canarygrass, wheatgrasses, and other crops, were identified as having merit for further development. Six of the seven institutions performing the screening included switchgrass among the species recommended for further development in their region and all recommended that perennial grasses be given high research priority. Reasons for the selection of switchgrass included demonstration of relatively high, reliable productivity across a wide geographical range, suitability for marginal quality land, low water and nutrient requirements, and other positive environmental attributes. Crop screening results, economic and environmental assessments by the Biofuels Feedstock Development Program staff, and Department of Energy funding limitations all contributed to the decision to further develop only switchgrass as a model or prototype species in 1991. The following ten year focus on development of switchgrass as a bioenergy crop proved the value of focusing on a single model herbaceous crop. The advancements and attention gained were sufficient to give government leaders, policymakers, farmers, and biofuel industry developers the confidence that lignocellulosic crops could support an economically viable and environmentally sustainable biofuel industry in the U.S.

Community dynamics and glycoside hydrolase activities of thermophilic bacterial consortia adapted to switchgrass  

DOE Green Energy (OSTI)

Industrial-scale biofuel production requires robust enzymatic cocktails to produce fermentable sugars from lignocellulosic biomass. Thermophilic bacterial consortia are a potential source of cellulases and hemicellulases adapted to harsher reaction conditions than commercial fungal enzymes. Compost-derived microbial consortia were adapted to switchgrass at 60 C to develop thermophilic biomass-degrading consortia for detailed studies. Microbial community analysis using small-subunit rRNA gene amplicon pyrosequencing and short-read metagenomic sequencing demonstrated that thermophilic adaptation to switchgrass resulted in low-diversity bacterial consortia with a high abundance of bacteria related to thermophilic paenibacilli, Rhodothermus marinus, and Thermus thermophilus. At lower abundance, thermophilic Chloroflexi and an uncultivated lineage of the Gemmatimonadetes phylum were observed. Supernatants isolated from these consortia had high levels of xylanase and endoglucanase activities. Compared to commercial enzyme preparations, the endoglucanase enzymes had a higher thermotolerance and were more stable in the presence of 1-ethyl-3-methylimidazolium acetate ([C2mim][OAc]), an ionic liquid used for biomass pretreatment. The supernatants were used to saccharify [C2mim][OAc]-pretreated switchgrass at elevated temperatures (up to 80 C), demonstrating that these consortia are an excellent source of enzymes for the development of enzymatic cocktails tailored to more extreme reaction conditions.

Historical Perspective on How and Why Switchgrass was Selected as a "Model" High-Potential Energy Crop  

Science Conference Proceedings (OSTI)

A review of several publications of the Biofuels Feedstock Development Program, and final reports from the herbaceous crop screening trials suggests that there were several technical and non-technical factors that influenced the decision to focus on one herbaceous "model" crop species. The screening trials funded by the U.S. Department of Energy in the late 1980's to early 1990's assessed a wide range of about 34 species with trials being conducted on a wide range of soil types in 31 different sites spread over seven states in crop producing regions of the U.S. While several species, including sorghums, reed canarygrass and other crops, were identified as having merit for further development, the majority of institutions involved in the herbaceous species screening studies identified switchgrass as having high priority for further development. Six of the seven institutions included switchgrass among the species recommended for further development in their region and all institutions recommended that perennial grasses be given high research priority. Reasons for the selection of switchgrass included the demonstration of relatively high, reliable productivity across a wide geographical range, suitability for marginal quality land, low water and nutrient requirements, and positive environmental attributes. Economic and environmental assessments by Oak Ridge National Laboratory's Biofuels Feedstock Development Program staff together with the screening project results, and funding limitations lead to making the decision to further develop only switchgrass as a "model" or "prototype" species in about 1990. This paper describes the conditions under which the herbaceous species were screened, summarizes results from those trials, discusses the various factors which influenced the selection of switchgrass, and provides a brief evaluation of switchgrass with respect to criteria that should be considered when selecting and developing a crop for biofuels and bioproducts.

EBS Radionuclide Transport Abstraction  

Science Conference Proceedings (OSTI)

The purpose of this report is to develop and analyze the engineered barrier system (EBS) radionuclide transport abstraction model, consistent with Level I and Level II model validation, as identified in ''Technical Work Plan for: Near-Field Environment and Transport: Engineered Barrier System: Radionuclide Transport Abstraction Model Report Integration'' (BSC 2005 [DIRS 173617]). The EBS radionuclide transport abstraction (or EBS RT Abstraction) is the conceptual model used in the total system performance assessment for the license application (TSPA-LA) to determine the rate of radionuclide releases from the EBS to the unsaturated zone (UZ). The EBS RT Abstraction conceptual model consists of two main components: a flow model and a transport model. Both models are developed mathematically from first principles in order to show explicitly what assumptions, simplifications, and approximations are incorporated into the models used in the TSPA-LA. The flow model defines the pathways for water flow in the EBS and specifies how the flow rate is computed in each pathway. Input to this model includes the seepage flux into a drift. The seepage flux is potentially split by the drip shield, with some (or all) of the flux being diverted by the drip shield and some passing through breaches in the drip shield that might result from corrosion or seismic damage. The flux through drip shield breaches is potentially split by the waste package, with some (or all) of the flux being diverted by the waste package and some passing through waste package breaches that might result from corrosion or seismic damage. Neither the drip shield nor the waste package survives an igneous intrusion, so the flux splitting submodel is not used in the igneous scenario class. The flow model is validated in an independent model validation technical review. The drip shield and waste package flux splitting algorithms are developed and validated using experimental data. The transport model considers advective transport and diffusive transport from a breached waste package. Advective transport occurs when radionuclides that are dissolved or sorbed onto colloids (or both) are carried from the waste package by the portion of the seepage flux that passes through waste package breaches. Diffusive transport occurs as a result of a gradient in radionuclide concentration and may take place while advective transport is also occurring, as well as when no advective transport is occurring. Diffusive transport is addressed in detail because it is the sole means of transport when there is no flow through a waste package, which may dominate during the regulatory compliance period in the nominal and seismic scenarios. The advective transport rate, when it occurs, is generally greater than the diffusive transport rate. Colloid-facilitated advective and diffusive transport is also modeled and is presented in detail in Appendix B of this report.

Effects of Biochar Recycling on Switchgrass Growth and Soil and Water Quality in Bioenergy Production Systems  

E-Print Network (OSTI)

Intensive biomass production in emerging bioenergy systems could increase nonpoint-source sediment and nutrient losses and impair surface and groundwater quality. Recycling biochar, a charcoal byproduct from pyrolysis of biomass, provides potential sources of mineral nutrients and organic carbon for sustaining biomass productivity and preserving soil and water. Yet, research is needed to verify that recycling of pyrolysis biochars will enhance crop growth and soil and environmental quality similar to black carbon or biochar derived from burning of biomass in tropical or Terra Preta soils. The experimental design of this study consisted of 3 replications and four biochar rates (0, 4, 16, and 64 Mg ha-1) incorporated in both a sandy loam and clay soil with and without fertilizer sources of N, P, and K. The sandy loam and clay soils were studied in separate experiments within a set of 24 box lysimeters seeded with switchgrass. Simulated rain was applied at 50 percent and 100 percent establishment of switchgrass for each soil type. Runoff and leachate were collected and analyzed for total and dissolved N, P, K and organic C. After the second rain event, each soil type and the accumulated switchgrass was sampled and analyzed. In the Boonville soil, biochar applied at 64 Mg ha-1 decreased switchgrass emergence from 42 percent to 14 percent when compared to soil alone. In the Burleson soil, 64 Mg ha-1 biochar had no effect (P > 0.05) on biomass production or leaf area index (LAI). Fertilizer N, P, and K had no effect (P > 0.05) on switchgrass emergence for either soil, but did increase (P biochar increased (P biochar receiving supplemental N, P, and K fertilizer also resulted in greater runoff concentrations of DRP. Emergence tests under increased heat showed electrical conductivities of soil-water solutions to be as high as 600 microS cm-1, even after biochar was washed with acetone and water to remove residual oils and tars and soluble salts. Increasing biochar rates decreased soil bulk density and increased pH and SOC in the 0- to 5-cm depth of soil. As a result of high nutrient recovery during pyrolysis (58 percent of total N, 86 percent of total P and 101 percent of total K), high rates of biochar applied at 64 Mg ha-1 increased mass losses of TN, TP, and TK from both soils. Yet, the mass balance of nutrients showed a surplus of N, P, and K at 64 Mg ha-1 biochar, which suggests some nutrient inputs are not plant available and remain in soil. Careful management of biochar, especially at high rates with these high nutrient contents, is critical when trying to improve soil fertility while protecting water quality.

Energy Optimization of Bioethanol Production via Gasification of Switchgrass. Revision submitted to AIChE  

E-Print Network (OSTI)

In this paper, we address the conceptual design of the bioethanol process from switchgrass via gasification. A superstructure is postulated for optimizing energy use that embeds direct or indirect gasification, followed by steam reforming or partial oxidation. Next, the gas composition is adjusted with membrane-PSA or water gas shift. Membrane separation, absorption with ethanol-amines and PSA are considered for the removal of sour gases. Finally, two synthetic paths are considered, high alcohols catalytic process with two possible distillation sequences, and syngas fermentation with distillation, corn grits, molecular sieves and pervaporation as alternative deshydration processes. The optimization of the superstructure is formulated as an MINLP problem using short-cut models, and solved through a special decomposition scheme that is followed by heat integration. The optimal process consists of direct gasification followed by steam reforming, removal of the excess of hydrogen and catalytic synthesis, yielding a potential operating cost of $0.41/gal

DEVELOPMENT OF A POPULATION BALANCE MODEL TO SIMULATE FRACTIONATION OF GROUND SWITCHGRASS  

SciTech Connect

The population balance model represents a time-dependent formulation of mass conservation for a ground biomass that flows through a set of sieves. The model is suitable for predicting the change in size and distribution of ground biomass while taking into account the flow rate processes of particles through a grinder. This article describes the development and application of this model to a switchgrass grinding operation. The mass conservation formulation of the model contains two parameters: breakage rate and breakage ratio. A laboratory knife mill was modified to act as a batch or flow-through grinder. The ground switchgrass was analyzed over a set of six Tyler sieves with apertures ranging from 5.66 mm (top sieve) to 1 mm (bottom sieve). The breakage rate was estimated from the sieving tests. For estimating the breakage ratio, each of the six fractions was further ground and sieved to 11 fractions on a set of sieves with apertures ranging from 5.66 to 0.25 mm (and pan). These data formed a matrix of values for determining the breakage ratio. Using the two estimated parameters, the transient population balance model was solved numerically. Results indicated that the population balance model generally underpredicted the fractions remaining on sieves with 5.66, 4.00, and 2.83 mm apertures and overpredicted fractions remaining on sieves with 2.00, 1.41, and 1.00 mm apertures. These trends were similar for both the batch and flow-through grinder configurations. The root mean square of residuals (RSE), representing the difference between experimental and simulated mass of fractions, was 0.32 g for batch grinding and 0.1 g for flow-through grinding. The breakage rate exhibited a linear function of the logarithm of particle size, with a regression coefficient of 0.99.

Overview of the Chariton Valley switchgrass project: A part of the biomass power for rural development initiative  

DOE Green Energy (OSTI)

Investigation of renewable energy in Iowa is centering on the use of agricultural crops to generate electricity. Switchgrass, a native grass of Iowa, is one of the most promising biomass producers. Chariton Valley RC and D Inc., a USDA affiliated rural development organization based in southern Iowa and Alliant Power, a major Iowa energy company, are leading a statewide coalition of public and private interests to develop a sustainable biomass industry. Chariton Valley RC and D is working with local producers and the agricultural professionals to develop a biomass supply infrastructure. Alliant Power is working to develop the technology to convert agricultural crops to energy to serve as the basis for sustainable commercial energy production. Iowa State University and others are assessing the long-term potential of gasification for converting switchgrass to energy. Plans call for modifications to a 750 MW Alliant Power coal plant that will allow switchgrass to be co-fired with coal. A 5% co-fire rate would produce 35 MW of electrical power production and require 50,000 acres of dedicated biomass supply in southern Iowa. Growing biomass crops on erosive lands, then using them as a substitute fuel in coal-fired boilers can potentially reduce air pollution, greenhouse gas emissions, soil erosion and water pollution.

Abstract  

E-Print Network (OSTI)

A re-evaluation of the Molten Salt Breeder Reactor concept has revealed problems related to its safety and to the complexity of the reprocessing considered. A reflection is carried out anew in view of finding innovative solutions leading to the Thorium Molten Salt Reactor concept. Several main constraints are established and serve as guides to parametric evaluations. These then give an understanding of the influence of important core parameters on the reactors operation. The aim of this paper is to discuss this vast research domain and to single out the Molten Salt Reactor configurations that deserve further evaluation.

ABSTRACT  

E-Print Network (OSTI)

More and more, educational frameworks and accreditation bodies recommend implementing a system to evaluate and improve the quality of higher education institutions. This paper describes a student self-evaluation of a French engineering school which was carried out with an external institution as client. It describes the methodology and standards adopted by the students in order to conduct the evaluation, interview stakeholders, and rate compliance with maturity levels. An analysis of the quantitative and qualitative results of this evaluation is drawn, both from the quality assurance and student perspectives. The benefits, bias, and difficulties of this student-led institution evaluation are discussed. Finally, in this paper, the authors identify the skills specific to quality assurance engineers which this project allowed students to develop. They conclude on possible future issues concerning evaluation, such as student-led cross-evaluations among institutions. This paper will permit readers (i) to identify the strengths and weaknesses of a student-led evaluation, (ii) to validate or not the opportunity of dedicated student projects within their programs to facilitate the continuous improvement loop, and (iii) to underline specific student skills developed in such projects.

KNIFE MILL COMMINUTION ENERGY ANALYSIS OF SWITCHGRASS, WHEAT STRAW, AND CORN STOVER AND CHARACTERIZATION OF PARTICLE SIZE DISTRIBUTIONS  

Science Conference Proceedings (OSTI)

Biomass preprocessing and pretreatment technologies such as size reduction and chemical preconditioning are aimed at reducing the cost of ethanol production from lignocellulosic biomass. Size reduction is an energy-intensive biomass preprocessing unit operation. In this study, switchgrass, wheat straw, and corn stover were chopped in an instrumented knife mill to evaluate size reduction energy and corresponding particle size distribution as determined with a standard forage sieve analyzer. Direct mechanical power inputs were determined using a dedicated data acquisition system for knife mill screen openings from 12.7 to 50.8 mm, rotor speeds between 250 and 500 rpm, and mass feed rates from 1 to 11 kg/min. A speed of 250 rpm gave optimum performance of the mill. Optimum feed rates for 25.4 mm screen and 250 rpm were 7.6, 5.8, and 4.5 kg/min for switchgrass, wheat straw, and corn stover, respectively. Total specific energy (MJ/Mg) was defined as the size reduction energy required to operate the knife mill plus that imparted to the biomass. Effective specific energy was defined as the energy imparted to the biomass. For these conditions, total specific energies were 27.3, 37.9, and 31.9 MJ/Mg and effective specific energies were 10.1, 15.5, and 3.2 MJ/Mg for switchgrass, wheat straw, and corn stover, respectively. These results demonstrated that biomass selection affects the size reduction energy, even for biomass with similar features. Second-order polynomial equations for the total specific energy requirement fitted well (R2 > 0.95) as a function of knife mill screen size, mass feed rate, and speed for biomass materials tested. The Rosin-Rammler equation fitted the cumulative undersize mass of switchgrass, wheat straw, and corn stover chop passed through ASABE sieves with high R2 (>0.983). Knife mill chopping of switchgrass, wheat straw, and corn stover resulted in particle size distributions classified as 'well-graded strongly fine-skewed mesokurtic', 'well-graded fine-skewed mesokurtic', and 'well-graded fine-skewed mesokurtic', respectively, for small knife mill screen sizes (12.7 to 25.4 mm) and distributions classified as 'well-graded fine-skewed mesokurtic', 'well-graded strongly fine-skewed mesokurtic', and 'well-graded fine-skewed mesokurtic', respectively, for the large screen size (50.8 mm). Total and effective specific energy values per unit size reduction of wheat straw were greater compared to those for switchgrass. Corn stover resulted in reduced total and effective specific energy per unit size reduction compared to wheat straw for the same operating conditions, but higher total specific energy per unit size reduction and lesser effective specific energy per unit size reduction compared to switchgrass. Data on minimized total specific energy with corresponding particle spectra will be useful for preparing feed material with a knife mill for subsequent grinding with finer size reduction devices.

Proteogenomic Analysis of a Thermophilic Bacterial Consortium Adapted to Deconstruct Switchgrass  

SciTech Connect

Thermophilic bacteria are a potential source of enzymes for the deconstruction of lignocellulosic biomass. However, the complement of proteins used to deconstruct biomass and the specific roles of different microbial groups in thermophilic biomass deconstruction are not well-explored. Here we report on the metagenomic and proteogenomic analyses of a compost-derived bacterial consortium adapted to switchgrass at elevated temperature with high levels of glycoside hydrolase activities. Near-complete genomes were reconstructed for the most abundant populations, which included composite genomes for populations closely related to sequenced strains of Thermus thermophilus and Rhodothermus marinus, and for novel populations that are related to thermophilic Paenibacilli and an uncultivated subdivision of the littlestudied Gemmatimonadetes phylum. Partial genomes were also reconstructed for a number of lower abundance thermophilic Chloroflexi populations. Identification of genes for lignocellulose processing and metabolic reconstructions suggested Rhodothermus, Paenibacillus and Gemmatimonadetes as key groups for deconstructing biomass, and Thermus as a group that may primarily metabolize low molecular weight compounds. Mass spectrometry-based proteomic analysis of the consortium was used to identify .3000 proteins in fractionated samples from the cultures, and confirmed the importance of Paenibacillus and Gemmatimonadetes to biomass deconstruction. These studies also indicate that there are unexplored proteins with important roles in bacterial lignocellulose deconstruction.

Investigation of an integrated switchgrass gasification/fuel cell power plant. Final report for Phase 1 of the Chariton Valley Biomass Power Project  

DOE Green Energy (OSTI)

The Chariton Valley Biomass Power Project, sponsored by the US Department of Energy Biomass Power Program, has the goal of converting switchgrass grown on marginal farmland in southern Iowa into electric power. Two energy conversion options are under evaluation: co-firing switchgrass with coal in an existing utility boiler and gasification of switchgrass for use in a carbonate fuel cell. This paper describes the second option under investigation. The gasification study includes both experimental testing in a pilot-scale gasifier and computer simulation of carbonate fuel cell performance when operated on gas derived from switchgrass. Options for comprehensive system integration between a carbonate fuel cell and the gasification system are being evaluated. Use of waste heat from the carbonate fuel cell to maximize overall integrated plant efficiency is being examined. Existing fuel cell power plant design elements will be used, as appropriate, in the integration of the gasifier and fuel cell power plant to minimize cost complexity and risk. The gasification experiments are being performed by Iowa State University and the fuel cell evaluations are being performed by Energy Research Corporation.

The usability of switchgrass, rice straw, and logging residue as feedstocks for power generation in East Texas  

E-Print Network (OSTI)

This thesis examines the economic implications of using agriculturally based feedstock for bio-energy production in East Texas. Specifically I examined the use of switchgrass, rice straw, and logging residue as a feedstock for electrical power generation in East Texas replacing coal. To examine the effects of such a substitution, an environmental bio-complexity approach is used to analyze the interactions of agricultural, technological, economic, and environmental factors. In particular, lifecycle analysis (LCA) and Cost-Benefit analysis is used. The results show that as we use more bio-energy for power generation, we will get less Greenhouse Gas (GHG) emission, which will be an environmental benefit in the long run. The main problem is that cost increases. Current biomass feedstock production costs are generally too high for biomass feedstock to replace coal in power generation. However I find that GHG offset prices can make biomass economically attractive. In particular GHG offset prices and forgiveness for the emissions from combustion based on photosynthetic absorption would raise the price people would be willing to pay for biomass feedstock making it competitive.

Combined inactivation of the Clostridium cellulolyticum lactate and malate dehydrogenase genes substantially increases ethanol yield from cellulose and switchgrass fermentations  

SciTech Connect

Background: The model bacterium Clostridium cellulolyticum efficiently hydrolyzes crystalline cellulose and hemicellulose, using cellulosomes to degrade lignocellulosic biomass. Although it imports and ferments both pentose and hexose sugars to produce a mixture of ethanol, acetate, lactate, H2 and CO2, the proportion of ethanol is low, which impedes its use in consolidated bioprocessing for biofuels. Therefore genetic engineering will likely be required to improve the ethanol yield. Random mutagenesis, plasmid transformation, and heterologous expression systems have previously been developed for C. cellulolyticum, but targeted mutagenesis has not been reported for this organism. Results: The first targeted gene inactivation system was developed for C. cellulolyticum, based on a mobile group II intron originating from the Lactococcus lactis L1.LtrB intron. This markerless mutagenesis system was used to disrupt both the paralogous L-lactate dehydrogenase (Ccel_2485; ldh) and L-malate dehydrogenase (Ccel_0137; mdh) genes, distinguishing the overlapping substrate specificities of these enzymes. Both mutations were then combined in a single strain. This double mutant produced 8.5-times more ethanol than wild-type cells growing on crystalline cellulose. Ethanol constituted 93% of the major fermentation products (by molarity), corresponding to a molar ratio of ethanol to organic acids of 15, versus 0.18 in wild-type cells. During growth on acid-pretreated switchgrass, the double mutant also produced four-times as much ethanol as wild-type cells. Detailed metabolomic analyses identified increased flux through the oxidative branch of the mutant s TCA pathway. Conclusions: The efficient intron-based gene inactivation system produced the first gene-targeted mutations in C. cellulolyticum. As a key component of the genetic toolbox for this bacterium, markerless targeted mutagenesis enables functional genomic research in C. cellulolyticum and rapid genetic engineering to significantly alter the mixture of fermentation products. The initial application of this system successfully engineered a strain with high ethanol productivity from complex biomass substrates.

Lignin is an integral component of secondary plant cell walls that provides structural rigidity to the cell wall but it interferes with the conversion of cellulose to fermentable sugars by prevent- ing chemical access to cellulose. Thus, one strategy for improving production of cellulosic ethanol is the down- regulation of lignin in plants. To achieve this goal, it is important

Bell & Yelugere L. Krishnamurthy & Kelly D. Craven Received: 24 November 2010 / Accepted: 12 December 2010 # Kevin D. Hyde 2010 Abstract This study was conducted to explore fungal endophyte communities inhabiting native switchgrass plants from the tallgrass prairie of northern Oklahoma. The primary focus was to isolate these endophytes in pure culture from surface-sterilized plant tissues and provide taxonomic identifications based on comparative analysis of ITS rDNA gene sequences. From these data, we evaluated the biodiversity of these potentially beneficial endosym- bionts from this rapidly disappearing habitat of the Great Plains. While important from a strictly

Evaluating Model Abstractions: A Quantitative Approach  

E-Print Network (OSTI)

An \\evaluation " approach devised for an inductive reasoning system called Logic-based Discrete-event Inductive Reasoner is the focus of this paper. The underlying inductive reasoning methodology utilizes abstractions as its primary means to deal with lack ofknowledge. Based on abstractions and their treatments as assumptions, the Logic-based Discrete-event Inductive Reasoning system allows non-monotonic predictions. The evaluation approach takes into account explicitly the role of abstractions employed in non-monotonically derived multiple predictions. These predictions are ranked according to the type and number of abstractions used. The proposed evaluation approach is also discussed in relation to the dichotomy of model validation and simulation correctness.

Collected abstracts on particle beam diagnostic systems  

SciTech Connect

This report contains a compilation of abstracts on work related to particle beam diagnostics for high temperature plasmas. The abstracts were gathered in early 1978 and represent the status of the various programs as of that date. It is not suggested that this is a comprehensive list of all the work that is going on in the development of particle beam diagnostics, but it does provide a representative view of the work in this field. For example, no abstracts were received from the U.S.S.R. even though they have considerable activity in particle beam diagnostics.

Intra-annual changes in biomass, carbon, and nitrogen dynamics at 4-year old switchgrass field trials in West Tennessee, USA  

Science Conference Proceedings (OSTI)

Switchgrass is a potential bioenergy crop that could promote soil C sequestration in some environments. We compared four cultivars on a well-drained Alfisol to test for differences in biomass, C, and N dynamics during the fourth growing season. There was no difference (P > 0.05) among cultivars and no significant cultivar x time interaction in analyses of dry mass, C stocks, or N stocks in aboveground biomass and surface litter. At the end of the growing season, mean (SE) aboveground biomass was 2.10.13 kg m-2, and surface litter dry mass was approximately 50% of aboveground biomass. Prior to harvest, the live root:shoot biomass ratio was 0.76. There was no difference (P > 0.05) among cultivars for total biomass, C, and N stocks belowground. Total belowground biomass (90-cm soil depth) as well as coarse (greater than or equal to 1 mm diameter) and fine (< 1 mm diameter) live root biomass increased from April to October. Dead roots were less than 7% of live root biomass to a depth of 90 cm. Net production of total belowground biomass (505 132 g m-2) occurred in the last half of the growing season. The increase in total live belowground biomass (426 139 g m-2) was more or less evenly divided among rhizomes, coarse, and fine roots. The N budget for annual switchgrass production was closely balanced with 6.3 g N m-2 removed by harvest of aboveground biomass and 6.7 g N m-2 supplied by fertilization. At the location of our study in west Tennessee, intra-annual changes in biomass, C, and N stocks belowground were of greater importance to crop management for C sequestration than were differences among cultivars.

Despite strong artificial noise, processing using remote referencing and Sutarno phase consistent smoothing revealed significant results from 10 out of 16 sites. Indication for 1-D structures was found in the shortest periods, 2-D effects in the periods up to 40 s, and 3-D effects in the long period range. Since 3-D effects were found in the longer periods, 2-D inversion was carried out for periods smaller than 40 s. The results of the inversion are consistent with the geology of the geothermal site and distinguish well the sediments from the granitic basement including the structures given by the faults. A conductive anomaly with a resistivity of about 3 Ωm has been found at a depth down to 2000 m in the area of the Soultz and Kutzenhausen faults, which is attributed to geothermal processes.

Data Abstraction for CSP-OZ  

E-Print Network (OSTI)

. CSP-OZ is an integrated formal method which combines the state-oriented method Object-Z with the process algebra CSP, thereby allowing a description of static as well as dynamic aspects of a system. Checking correctness of CSP-OZ specifications can be done via a translation into (FDR-)CSP, on which automatic verification can be performed with the tool FDR if the resulting CSP process is not too large to be processed. This paper investigates how data abstraction techniques can be used to bring a translated specification within range of automatic verification. 1

Physical and Chemical Environmental Abstraction Model  

Science Conference Proceedings (OSTI)

As directed by a written development plan (CRWMS M&O 1999a), Task 1, an overall conceptualization of the physical and chemical environment (P/CE) in the emplacement drift is documented in this Analysis/Model Report (AMR). Included are the physical components of the engineered barrier system (EBS). The intended use of this descriptive conceptualization is to assist the Performance Assessment Department (PAD) in modeling the physical and chemical environment within a repository drift. It is also intended to assist PAD in providing a more integrated and complete in-drift geochemical model abstraction and to answer the key technical issues raised in the U.S. Nuclear Regulatory Commission (NRC) Issue Resolution Status Report (IRSR) for the Evolution of the Near-Field Environment (NFE) Revision 2 (NRC 1999). EBS-related features, events, and processes (FEPs) have been assembled and discussed in ''EBS FEPs/Degradation Modes Abstraction'' (CRWMS M&O 2000a). Reference AMRs listed in Section 6 address FEPs that have not been screened out. This conceptualization does not directly address those FEPs. Additional tasks described in the written development plan are recommended for future work in Section 7.3. To achieve the stated purpose, the scope of this document includes: (1) the role of in-drift physical and chemical environments in the Total System Performance Assessment (TSPA) (Section 6.1); (2) the configuration of engineered components (features) and critical locations in drifts (Sections 6.2.1 and 6.3, portions taken from EBS Radionuclide Transport Abstraction (CRWMS M&O 2000b)); (3) overview and critical locations of processes that can affect P/CE (Section 6.3); (4) couplings and relationships among features and processes in the drifts (Section 6.4); and (5) identities and uses of parameters transmitted to TSPA by some of the reference AMRs (Section 6.5). This AMR originally considered a design with backfill, and is now being updated (REV 00 ICN1) to address the design without backfill. This design change is described in ''Monitored Geologic Repository Project Description Document'' (CRWMS M&O 2000c). The design change will result in a greater ability of the waste packages to reject heat after closure of the repository, thereby maintaining the two thermal requirements. The first requirement is for protection of the fuel cladding, and the second requires that a section of the rock pillar between drifts remain below the boiling temperature of water, providing a path for water drainage.

VEST: Abstract Vector Calculus Simplification in Mathematica  

SciTech Connect

We present a new package, VEST (Vector Einstein Summation Tools), that performs abstract vector calculus computations in Mathematica. Through the use of index notation, VEST is able to reduce scalar and vector expressions of a very general type using a systematic canonicalization procedure. In addition, utilizing properties of the Levi-Civita symbol, the program can derive types of multi-term vector identities that are not recognized by canonicalization, subsequently applying these to simplify large expressions. In a companion paper [1], we employ VEST in the automation of the calculation of Lagrangians for the single particle guiding center system in plasma physics, a computation which illustrates its ability to handle very large expressions. VEST has been designed to be simple and intuitive to use, both for basic checking of work and more involved computations. __________________________________________________

Improving abstract interpretations by combining domains  

E-Print Network (OSTI)

This article considers static analysis based on abstract interpretation of logic programs over combined domains. It is known that analyses over combined domains provide more information potentially than obtained by the independent analyses. However, the construction of a combined analysis often requires redefining the basic operations for the combined domain. A practical ap-proach to maintain precision in combined analyses of logic programs which reuses the individual analyses and does not redefine the basic operations is illustrated, The advantages of the approach are that (1) proofs of correctness for the new domains are not required and (2) implementations can be reused. The approach is demonstrated by showing that a combined sharing analysis constructed from old proposals compares well with other new proposals suggested in recent

Compile-time Derivation of Variable Dependency Using Abstract Interpretation  

E-Print Network (OSTI)

Traditional schemes for abstract interpretation-based global analysis of logic programs generally focus on obtaining procedure argument mode and type information. Variable sharing information is often given only the attention needed to preserve the correctness of the analysis. However, such sharing information can be very useful. In particular, it can be used for predicting runtime goal independence, which can eliminate costly run-time checks in and-parallel execution. In this paper, a new algorithm for doing abstract interpretation in logic programs is described which concentrates on inferring the dependencies of the terms bound to program variables with increased precision and at all points in the execution of the program, rather than just at a procedure level. Algorithms are presented for computing abstract entry and success substitutions which extensively domain independent fixpoint algorithm is presented and described in detail. The algorithms are illustrated with examples. Finally, results from an implementation of the abstract interpreter are presented. 1

Environment, First-Order Abstraction in Multiagent Systems  

E-Print Network (OSTI)

Current practice in multiagent systems typically associates the environment with resources external to the agents and infrastructure for communication. Advanced uses of the environment are infrastructures for indirect coordination such as digital pheromones, or support for governed interaction as in electronic institutions. Yet, in general, the notion of environment is not well defined. Functionalities of the environment are often dealt with implicitly, or in an ad-hoc manner. This is not only poor engineering practice, it also hinders engineers to exploit the full potential of the environment in multiagent systems. In this paper, we put forward the environment as an explicit part of multiagent systems. We give a definition of the environment that states that the environment is a first-order abstraction in multiagent systems with a dual role: (1) the environment provides the surrounding conditions for agents to exists, which implies that the environment is an essential part of every multiagent system, and (2) the environment provides an exploitable design abstraction to build multiagent system applications. We discuss responsibilities of the environment in multiagent systems and we present a reference model for the environment that can serve as a basis for environment engineering. To illustrate the power of the environment as design abstraction, we show how the environment is successfully exploited in a real world application. Considering the environment as a first-order abstraction in multiagent systems opens up new horizons for research and development in multiagent systems. 1.

Determination of variable dependence information through abstract interpretation  

E-Print Network (OSTI)

Traditional schemes for abstract interpretation-based global analysis of logic programs generally focus on obtaining procedure argument mode and type information. Variable sharing information is often given only the attention needed to preserve the correctness of the analysis. However, such sharing information can be very useful. In particular, it can be used for predicting run-time goal independence, which can eliminate costly run-time checks in interpretation in logic programs is described which infers the dependencies of the terms bound to program variables with increased precision and at all points in the execution of the program, rather than just at a procedure level. Algorithms are presented for computing abstract entry and success substitutions which extensively keep track of variable aliasing and term dependence information. The algorithms are illustrated with examples. 1

Rethinking Abstractions for Big Data: Why, Where, How, and What  

E-Print Network (OSTI)

Big data refers to large and complex data sets that, under existing approaches, exceed the capacity and capability of current compute platforms, systems software, analytical tools and human understanding. Numerous lessons on the scalability of big data can already be found in asymptotic analysis of algorithms and from the high-performance computing (HPC) and applications communities. However, scale is only one aspect of current big data trends; fundamentally, current and emerging problems in big data are a result of unprecedented complexity--in the structure of the data and how to analyze it, in dealing with unreliability and redundancy, in addressing the human factors of comprehending complex data sets, in formulating meaningful analyses, and in managing the dense, power-hungry data centers that house big data. The computer science solution to complexity is finding the right abstractions, those that hide as much triviality as possible while revealing the essence of the problem that is being addressed. The "big data challenge" has disrupted computer science by stressing to the very limits the familiar abstractions which define the relevant subfields in data analysis, data management and the underlying parallel systems. As a result, not enough of these challenges are revealed by isolating abstractions in a traditional software stack or standard algorithmic and analytical techniques, and attempts to address complexity either oversimplify or require low-level management of details. The authors believe that the abstractions for big data need to be rethought, and this reorganization needs to evolve and be sustained through continued cross-disciplinary collaboration.

Small Business Innovation Research: Abstracts of Phase 1 awards, 1994  

SciTech Connect

The Small Business Innovation Research (SBIR) program enables DOE to obtain effective, innovative solutions to important problems through the private sector, which has a commercial incentive to pursue the resulting technology and bring it to the marketplace. The growing number of awardees, many of them started in business in response to SBIR solicitations, is becoming a significant resource for the solution of high risk, high technology problems for the Department. As detailed here, this publication describes the technical efforts for SBIR Phase 1 awards in 1994. It is intended for the educated layman, and may be of particular interest to potential investors who wish to get in on the ground floor of exciting opportunities. Contained in this booklet are abstracts of the Phase 1 awards made in FY 1994 under the DOE SBIR program. The 212 Phase 1 projects described here were selected in a highly competitive process from a total of 2,276 grant applications received in response to the 1994 DOE annual SBIR Solicitation. The selections for awards were made on scientific and technical merit, as judged against the specific criteria listed in the Solicitation. Conclusions were reached on the basis of detailed reports returned by reviewers drawn from DOE laboratories, universities, private industry, and government. (Any discrepancies noted in prior DOE releases naming the firms selected for awards are due either to the firm changing its name after the award selection or to the firm not proceeding to a signed grant.) It is expected that between one-third and one-half of the Phase 1 projects will be continued into Phase 2. The work described in the abstracts is novel, high-risk research, but the benefits will also be potentially high if the objectives are met. Brief comments on the potential applications are given after each abstract. Individuals and organizations with an interest in the research described are encouraged to contact the appropriate small business directly.

THE DYNAMICS OF HYDROGEN ATOM ABSTRACTION FROM POLYATOMIC MOLECULES.  

DOE Green Energy (OSTI)

The hydrogen atom abstraction reaction is an important fundamental process that is extensively involved in atmospheric and combustion chemistry. The practical significance of this type of reaction with polyatomic hydrocarbons is manifest, which has led to many kinetics studies. The detailed understanding of these reactions requires corresponding dynamics studies. However, in comparison to the A + HX {radical} AH + X reactions, the study of the dynamics of A + HR {yields} AH + R reactions is much more difficult, both experimentally and theoretically (here and in the following, A stands for an atom, X stands for a halogen atom, and R stands for a polyatomic hydrocarbon radical). The complication stems from the structured R, in contrast to the structureless X. First of all, there are many internal degrees of freedom in R that can participate in the reaction. In addition, there are different carbon sites from which an H atom can be abstracted, and the dynamics are correspondingly different; there are also multiple identical carbon sites in HR and in the picture of a local reaction, there exist competitions between neighboring H atoms, and so on. Despite this complexity, there have been continuing efforts to obtain insight into the dynamics of these reactions. In this chapter, some examples are presented, including the reactions of ground state H, Cl, and O atoms, with particular focus on our recent work using imaging to obtain the differential cross sections for these reactions.

However, the polarization direction of Hα emission from "secondary" beam neutrals that ionize, gyrate about field lines, and then charge exchange a second time differs from the polarization direction of the primary beam neutrals and thus confuses the calibration results.

15. international conference on plant growth substances: Program -- Abstracts  

SciTech Connect

Since the 14th Conference in Amsterdam in 1991, progress in plant hormone research and developmental plant biology has been truly astonishing. The five ``classical`` plant hormones, auxin, gibberellin, cytokinin, ethylene, and abscisic acid, have been joined by a number of new signal molecules, e.g., systemin, jasmonic acid, salicylic acid, whose biosynthesis and functions are being understood in ever greater detail. Molecular genetics has opened new vistas in an understanding of transduction pathways that regulate developmental processes in response to hormonal and environmental signals. The program of the 15th Conference includes accounts of this progress and brings together scientists whose work focuses on physiological, biochemical, and chemical aspects of plant growth regulation. This volume contains the abstracts of papers presented at this conference.

To guarantee this it is necessary to know upper bounds for the worst case execution times (WCETs). The accuracy of the prediction of WCETs depends strongly on the ability to model the features of the target processor.

Algebraic specification and program development by stepwise refinement (Extended Abstract)  

E-Print Network (OSTI)

. Various formalizations of the concept of "refinement step" as used in the formal development of programs from algebraic specifications are presented and compared. 1 Introduction Algebraic specification aims to provide a formal basis to support the systematic development of correct programs from specifications by means of verified refinement steps. Obviously, a central piece of the puzzle is how best to formalize concepts like "specification", "program" and "refinement step". Answers are required that are simple, elegant and general and which enjoy useful properties, while at the same time taking proper account of the needs of practice. Here I will concentrate on the last of these concepts, but first I need to deal with the other two. For "program", I take the usual approach of algebraic specification whereby programs are modelled as many-sorted algebras consisting of a collection of sets of data values together with functions over those sets. This level of abstraction is commens...

Preserved Access to Abstract Letter Identities Despite Abolished Letter . . .  

E-Print Network (OSTI)

In this paper, we discuss the letter processing difficulties of a patient (MS) with pure alexia after left hemisphere stroke who is unable to read any words aloud despite preserved writing and good performance at naming orally spelled words. MS is completely unable to name visually presented letters even though she can name them when they are presented in other modalities. Despite her poor naming, she can distinguish correctly oriented letters from mirror reversals and can perform accurate cross-case matching of visually presented letters. It, therefore, appears that MS is able to access the abstract identity of visually presented letters despite her total inability to name them. This is a more precise form of letter processing impairment than that which has been reported in previous cases of pure alexic patients who are unable to name visually presented letters [Caplan, L.R., & HedleyWhite, T. (1974). Cueing and memory function in alexia without agraphia: a case report. Brain, 115, 251-262; Miozzo, M., & Caramazza, A. (1998). Varieties of pure alexia: the case of failure to access graphemic representations. Cognitive Neuropsychology, 15, 203-238; Sevush, S., & Heilman, K.M. (1984). A case of literal alexia. Brain & Language, 22, 92-108]. It suggests that representations of the graphemic identities of letters used in reading are either modality specific or else they are hemisphere specific [Saffran, E.M., & Coslett, H.B. (1998). Implicit vs. letter-by-letter reading in pure alexia: a tale of two systems. Cognitive Neuropsychology, 15, 141-165]. Her letter processing impairment also appears to be different from that observed in a letter-by-letter reader [Perri, R., Bartolomeo, P., & Silveri, M.C. (1996). Letter dyslexia in a letter-by-letter reader. Brain & Language, 53,...

4th Annual DOE-ERSP PI Meeting: Abstracts  

Science Conference Proceedings (OSTI)

This contains abstracts from the 2009 Annual Environmental Remediation Sciences Program (ERSP) Principal Investigators (PI) Meeting. The ERSP seeks to advance fundamental science to understand, predict, and mitigate the impacts of environmental contamination from past nuclear weapons production and provide a scientific basis for the long-term stewardship of nuclear waste disposal. These ambitious goals cannot be achieved by any one project alone. Therefore, ERSP funds a combination of research programs at the DOE national laboratories, individual projects at universities and federal agencies, and large long(er)-term field site research. Integration of these activities to advance the ERSP goals is a constant challenge, but made significantly simpler by bringing together all funded ERSP researchers once a year to discuss the very latest research results. It is at these meetings where new ideas and/or scientific advancements in support of ERSP goals can be discussed and openly debated among all PIs in the program. The ERSP thrives, in part, on the new ideas, concepts, scientific connections, and collaborations generated as a result of these meetings. The annual PI Meeting is very much a working meeting with three major goals: (1) to provide opportunities for scientific interaction among the ERSP scientists, a critical element for the program; (2) to provide the ERSP program staff with an opportunity to evaluate the progress of each program and project; and (3) to showcase the ERSP to interested parties within DOE and within other federal agencies In addition to program managers from within OBER, there will be representatives from other offices within DOE and other federal agencies in attandance at the meeting.

2nd Annual DOE-ERSP PI Meeting: Abstracts  

Science Conference Proceedings (OSTI)

Welcome to the annual 2007 Environmental Remediation Sciences Program (ERSP) Principal Investigators (PIs) meeting. The purpose of this meeting is to bring together all of the lead PIs and key Co-PIs in the program to share and review the results of funded research from the past year. This meeting allows program managers from the Environmental Remediation Sciences Division (ERSD) within the Office of Biological and Environmental Research (OBER) to gauge the progress and significance of the funded research, and it is also an important venue to showcase ERSP research to interested parties within DOE and other invited federal agency representatives. Additionally, these meetings should serve as an opportunity for funded PIs to view their research in the context of the entire ERSP portfolio. Past ERSP meetings have been very important venues for detailed discussion of research results among PIs, development of new research ideas, fostering new collaborations and discussion with ERSD program managers on future research efforts and/or initiatives within the program. In short, these meetings are an important resource for both program managers and PIs. There will be only one ERSP PI meeting for 2007. In years past, ERSD has sponsored two PI meetings, one in the spring and a separate meeting in the fall that focused primarily on field research. However, this format tends to insulate laboratory-based research from the field research sponsored in the program and is incompatible with the ERSD view that laboratory-based research should progress towards understanding the relevant processes in natural environments at the field scale. Therefore the agenda for this year's PI meeting is well integrated with both lab-based and field-based projects, to allow for detailed discussion between PIs involved in each area. In the agenda, you will notice a more relaxed format than in years past. This year's meeting spans four days, but is less heavily regimented in terms of oral presentations and allows ample time for informal group discussions and poster presentations. The intent of this format is to foster informal discussion of research among PIs and ERSD program managers-discussion that is a hallmark of previous ERSD-sponsored meetings. Morning sessions will be dominated by oral presentations from PIs chosen by ERSD program managers to communicate key topics of research within the program. There is ample time during lunch and in the early afternoon for small group discussions/meetings prior to convening again in the later afternoon for oral presentations on field research conducted at the Integrated Field-Scale Subsurface Research Challenge sites (IFCs). Formal poster sessions begin after dinner. Abstracts for all poster presentations are listed within this meeting booklet. On behalf of the ERSD program managers and staff, we thank you for attending this year's PI meeting. We look forward to discussing the results of your research with you and your ideas for the future, and we hope that this meeting will continue as an important tradition for PIs in the program and serve as a valuable resource for your investigations.

/sup 14/CO/sub 2/ incorporation into C/sub 4/ acids by leaves of the C/sub 3/-C/sub 4/ intermediate species, Moricandia arvensis and Panicum milioides, at Gamma-levels of CO/sub 2/  

Science Conference Proceedings (OSTI)

The crucifer M. arvensis is a species with photorespiratory characteristics intermediate between C/sub 3/ and C/sub 4/ plants. Although the precise mechanism promoting decreased photorespiration has yet to be elucidated, evidence to date disfavors participation of C/sub 4/ metabolism. In order to conclusively assess the possible contribution, if any, of limited C/sub 4/ metabolism to the reduction of photorespiration, detached leaves of M. arvensis and M. moricandioides (C/sub 3/) were labeled with /sup 14/CO/sub 2/. When M. arvensis was illuminated and pulsed for 10 s the amount of label in malate increased from 4.5% of total soluble dpm fixed at 21% O/sub 2/ and 340 ..mu..l/l CO/sub 2/ to 10.3% at 20 ..mu..l/l. A two-fold increase was also evident for aspartate (from 2.9% to 6.5%). The C/sub 3/ Moricandia species failed to show a similar response to decreased CO/sub 2/. The physiological significance of the increase in C/sub 4/ acid-labeling which occurred in the intermediate species will be investigated by pulse-chase analyses of C/sub 4/ acids and glycine. Similar data for Panicum milioides (C/sub 3/-C/sub 4/) will also be presented.

An abstract interpretation scheme for groundness, freeness, and sharing analysis of logic programs  

E-Print Network (OSTI)

Static global analyses based on abstract interpretation have been used to derive properties of programs. The analyses differ in the expressiveness of the abstract domains and the precision and efficiency of domain operations. We extend an abstract domain defined by Jacobs and Langen and present new abstract domain operations to derive freeness, groundness, and sharing of variables in logic programs. Analysis of non-trivial programs shows that our method is more precise and more efficient than previous proposals.

CROP SCIENCE, VOL. 51, NOVEMBER- CROP SCIENCE, VOL. 51, NOVEMBER- DECEMBER 2011 RESEARCH S witchgrass (Panicum virgatum L.) is a warm-season peren- nial bunchgrass native to North America. Being one of the predominant species found in tallgrass prairies, switchgrass has traditionally been used for soil conservation and forage produc- tion (Bouton, 2007; Vogel and Jung, 2001). Because of its high biomass productivity, low nutrient requirement, and potential environmental benefits, switchgrass has been developed into a major herbaceous bioenergy crop for the production of cellulosic biofuels in recent years (Hisano et al., 2009; McLaughlin et al., 2006; Schmer et al., 2008). An important aspect of switchgrass taxonomy and reproduc- tive behavior is its grouping into two distinct ecotype categories:

Conceptual Framework and Levels of Abstraction for a Complex Large-Scale System  

SciTech Connect

A conceptual framework and levels of abstraction are created to apply across all potential threats. Bioterrorism is used as a complex example to describe the general framework. Bioterrorism is unlimited with respect to the use of a specific agent, mode of dissemination, and potential target. Because the threat is open-ended, there is a strong need for a common, systemic understanding of attack scenarios related to bioterrorism. In recognition of this large-scale complex problem, systems are being created to define, design and use the proper level of abstraction and conceptual framework in bioterrorism. The wide variety of biological agents and delivery mechanisms provide an opportunity for dynamic scale changes by the linking or interlinking of existing threat components. Concurrent impacts must be separated and evaluated in terms of a given environment and/or abstraction framework.

A New Approach to Abstract Machines - Introduction to the Theory of Configuration Machines  

E-Print Network (OSTI)

An abstract machine is a theoretical model designed to perform a rigorous study of computation. Such a model usually consists of configurations, instructions, programs, inputs and outputs for the machine. In this paper we formalize these notions as a very simple algebraic system, called a configuration machine. If an abstract machine is defined as a configuration machine consisting of primitive recursive functions then the functions computed by the machine are always recursive. The theory of configuration machines provides a useful tool to study universal machines.

Soil physical and hydrological properties under three biofuel crops in Ohio  

Science Conference Proceedings (OSTI)

While biofuel crops are widely studied and compared for their energy and carbon footprints, less is known about their effects on other soil properties, particularly hydrologic characteristics. Soils under three biofuel crops, corn (Zea mays), switchgrass (Panicum virgatum), and willow (Salix spp.), were analyzed seven years after establishment to assess the effects on soil bulk density ({rho}{sub b}), penetration resistance (PR), water-holding capacity, and infiltration characteristics. The PR was the highest under corn, along with the lowest associated water content, while PR was 50-60% lower under switchgrass. In accordance with PR data, surface (0-10 cm) bulk density also tended to be lower under switchgrass. Both water infiltration rates and cumulative infiltration amounts varied widely among and within the three crops. Because the Philip model did not fit the data, results were analyzed using the Kostiakov model instead. Switchgrass plots had an average cumulative infiltration of 69 cm over 3 hours with a constant infiltration rate of 0.28 cm min{sup -1}, compared with 37 cm and 0.11 cm min{sup -1} for corn, and 26 cm and 0.06 cm min{sup -1} for willow, respectively. Results suggest that significant changes in soil physical and hydrologic properties may require more time to develop. Soils under switchgrass may have lower surface bulk density, higher field water capacity, and a more rapid water infiltration rate than those under corn or willow.

The abstract boundary---a new approach to singularities of manifolds  

E-Print Network (OSTI)

A new scheme is proposed for dealing with the problem of singularities in General Relativity. The proposal is, however, much more general than this. It can be used to deal with manifolds of any dimension which are endowed with nothing more than an affine connection, and requires a family \\calc\\ of curves satisfying a {\\em bounded parameter property} to be specified at the outset. All affinely parametrised geodesics are usually included in this family, but different choices of family \\calc\\ will in general lead to different singularity structures. Our key notion is the {\\em abstract boundary\\/} or {\\em $a$-boundary\\/} of a manifold, which is defined for any manifold \\calm\\ and is independent of both the affine connection and the chosen family \\calc\\ of curves. The $a$-boundary is made up of equivalence classes of boundary points of \\calm\\ in all possible open embeddings. It is shown that for a pseudo-Riemannian manifold $(\\calm,g)$ with a specified family \\calc\\ of curves, the abstract boundary points can then be split up into four main categories---regular, points at infinity, unapproachable points and singularities. Precise definitions are also provided for the notions of a {\\em removable singularity} and a {\\em directional singularity}. The pseudo-Riemannian manifold will be said to be singularity-free if its abstract boundary contains no singularities. The scheme passes a number of tests required of any theory of singularities. For instance, it is shown that all compact manifolds are singularity-free, irrespective of the metric and chosen family \\calc.

Modeling an Electronic Throttle Controller using the Timed Abstract State Machine Language and Toolset  

E-Print Network (OSTI)

A key challenge in the design and analysis of real-time systems is the integration of functional and non-functional properties into a single specification. In this paper, we present an integrated toolset based on the TASM language. The toolset is used to specify and analyze reactive embedded real-time systems. The toolset implements the features of the Timed Abstract State Machine (TASM) language, a novel specification language. The non-functional properties that can be expressed in the language include timing behavior and resource consumption. The toolset enables the creation of executable specifications with well-defined execution semantics, abstraction mechanisms, and composition semantics. The toolset includes facilities for editing, analyzing, and simulating TASM specifications. The features of the toolset are demonstrated using an Electronic Throttle Controller (ETC) from a major automotive vendor. The TASM toolset is used to analyze the mode switching logic of the ETC. The ETC is used to calculate fuel injection and air intake to optimize fuel consumption. The TASM toolset is used to analyze the resource consumption resulting from the mode switching logic, and to verify the completeness and consistency of the specification.

issu issu Abstract: In this note we consider compensation of the vertical angle at the IP that arises when the NLC beam enters the detector solenoid. While this angle is antisymmetric for e+e- collisions and does not affect luminosity, compensating this angle is desirable to guarantee knowledge of polarization at the IP. For the e-e- case compensation is necessary also from the luminosity point of view. We show in this note that the most effective compensation can be done locally, with a special dipole coil arrangement incorporated into the detector. It is shown that compensation can be achieved for both e+e- and e-e- case and that this scheme is compatible with beam size compensation by both the standard method, using skew quadrupoles, and by means of more advantageous

Total human exposure and indoor air quality: an automated bibliography (BLIS) with summary abstracts. Final report  

Science Conference Proceedings (OSTI)

The Bibliographic Literature Information System (BLIS) is a computerized data base with brief abstracts that comprehensively reviews literature on total human exposure to environmental pollution. Unpublished draft reports are listed, as well as final reports of the U.S. Government and other countries, reports by governmental research contractors, journal articles, and other contributions. The bibliography covers publications on exposure models, new field data, and newly emerging research methodologies. Although the bibliography covers the entire field of human-exposure methodology, emphasis is on those field studies measuring all the concentrations to which people may be exposed, including indoors, outdoors, or in-transit. Versions of the data base are available on floppy diskettes that can be accessed on MS-DOS computers with two-floppy-disk or hard-disk systems.

NREL photovoltaic subcontract reports: Abstracts and document control information, 1 August 1991--31 July 1992  

DOE Green Energy (OSTI)

This report contains document control information and abstracts for the National Renewable Energy Laboratory (NREL) subcontracted photovoltaic program publications. It also lists source information on additional publications that describe US Department of Energy (DOE) PV research activities. It is not totally exhaustive, so it lists NREL contacts for requesting further information on the DOE and NREL PV programs. This report covers the period from August 1, 1991, through July 31, 1992. The purpose of continuing this type of publication is to help people keep abreast of specific PV interests, while maintaining a balance on the costs to the PV program. The information in this report is organized under PV technology areas: Amorphous silicon research; polycrystalline thin films (including copper indium diselenide, cadmium telluride, and thin-film silicon); crystalline materials and advanced concepts (including silicon, gallium arsenide, and other group III-V materials); and PV manufacturing technology development (which may include manufacturing information for various types of PV materials).

An Approach to Evaluate Scientist Support in Abstract Workflows and Provenance Traces  

Science Conference Proceedings (OSTI)

Abstract workflows are useful to bridge the gap between scientists and technologists towards using computer systems to carry out scientific processes. Provenance traces provide evidence required to validate results and support their reuse. Assuming both technologies are based on formal semantics, a knowledge-based system that consistently merges both technologies is useful for scientists that produce data to document their data collecting and transformation processes; it is also useful for scientists that reuse data to assess scientific processes and resulting datasets produced by others. While evaluation of each technology is necessary for a given application, this work discusses their combined evaluation. The claim is that both technologies should complement each other and align consistently to a scientists perspective in order to be effective for science. Evaluation criteria are proposed based on lessons learned and exemplified for discussion.

An abstract-device interface for implementing portable parallel-I/O interfaces  

Science Conference Proceedings (OSTI)

Portable parallel programming has been hampered by the lack of a single, standard, portable application-programmer`s interface (API) for parallel I/O. Instead, the programmer must choose from several different APIs, many of which are not portable. To alleviate this problem, the authors have developed an abstract-device interface for parallel I/O, called ADIO. ADIO is not intended as a new API; rather, it is a strategy for implementing other APIs in a simple, portable, and efficient manner. ADIO facilitates the implementation of any existing or new API on any existing or new file system. ADIO thus enables users to experiment with different APIs, a feature that, they think, would help in the definition of a standard API. It also makes existing applications portable across a wide range of platforms. In this paper, they introduce the concept of ADIO. They describe the design of ADIO and its use in implementing APIs. They have currently implemented subsets of the Intel PFS, IBM PIOFS, and MPI-IO APIs on both the PFS and PIOFS file systems. As a result, they are able to run IBM PIOFS applications on the Intel Paragon, Intel PFS applications on the IBM SP, and MPI-IO applications on both systems. They report performance results obtained from two test programs and one real production application on the SP and Paragon. These results indicate that the performance overhead of using ADIO as an implementation strategy is negligible.

Toward Abstracting the Communication Intent in Applications to Improve Portability and Productivity  

SciTech Connect

Programming with communication libraries such as the Message Passing Interface (MPI) obscures the high-level intent of the communication in an application and makes static communication analysis difficult to do. Compilers are unaware of communication libraries specifics, leading to the exclusion of communication patterns from any automated analysis and optimizations. To overcome this, communication patterns can be expressed at higher-levels of abstraction and incrementally added to existing MPI applications. In this paper, we propose the use of directives to clearly express the communication intent of an application in a way that is not specific to a given communication library. Our communication directives allow programmers to express communication among processes in a portable way, giving hints to the compiler on regions of computations that can be overlapped with communication and relaxing communication constraints on the ordering, completion and synchronization of the communication imposed by specific libraries such as MPI. The directives can then be translated by the compiler into message passing calls that efficiently implement the intended pattern and be targeted to multiple communication libraries. Thus far, we have used the directives to express point-to-point communication patterns in C, C++ and Fortran applications, and have translated them to MPI and SHMEM.

Invariance properties of boundary sets of open embeddings of manifolds and their application to the abstract boundary  

E-Print Network (OSTI)

The {\\em abstract boundary\\/} (or {\\em {\\em a\\/}-boundary\\/}) of Scott and Szekeres \\cite{Scott94} constitutes a ``boundary'' to any $n$-dimensional, paracompact, connected, Hausdorff, $C^\\infty$-manifold (without a boundary in the usual sense). In general relativity one deals with a {\\em space-% time\\/} $(\\cM,g)$ (a 4-dimensional manifold $\\cM$ with a Lorentzian metric $g$), together with a chosen preferred class of curves in $\\cM$. In this case the {\\em a\\/}-boundary points may represent ``singularities'' or ``points at infinity''. Since the {\\em a\\/}-boundary itself, however, does not depend on the existence of further structure on the manifold such as a Lorentzian metric or connection, it is possible for it to be used in many contexts. In this paper we develop some purely topological properties of abstract boundary sets and abstract boundary points ({\\em a\\/}-boundary points). We prove, amongst other things, that compactness is invariant under boundary set equivalence, and introduce another invariant concept ({\\em isolation\\/}), which encapsulates the notion that a boundary set is ``separated'' from other boundary points of the same embedding. .......

Yuksel Yuksel University of Wisconsin Neutrino Mass, Mixing, and Supernovae Neutrino Detection Being chargeless and weakly interacting, neutrinos also thought, for many decades, to have no mass. This simple picture is continuously challenged by many experiments and observations, and has to be reconsidered to include new physics. Today, neutrinos are rapidly becoming tools to probe early epochs of universe, stellar evolution, mechanism behind supernovae explosions, nucleosynthesis, and weak interactions. The last galactic supernova, 1987A which was observed with neutrinos preceding the light, confirmed our basic understanding of mechanism behind the SN explosion. I will briefly review neutrino mass, mixing, oscillations, discuss some of the implications of oscillations and some strategies to circumvent the

Bhagwat Bhagwat Kent State University Modeling QCD for Hadron Phenomenology In seeking to improve QCD modeling of hadron physics, we have determined the amount of infrared enhancement, above that exhibited by the gluon two-point function, necessary to correlate quenched-lattice QCD data for the dressed-quark propagator and the dressed gluon propagator via the rainbow gap equation. The solution of this gap equation is used as input for a model of the dressed quark-gluon vertex at zero gluon momentum, formed from a non-perturbative extension of the two Feynman diagrams that contribute at one loop in perturbation theory. Comparison is made with recent quenched-lattice QCD data. Possible implications for hadron physics are discussed. Back to the theory seminar page.

Renato Higa Renato Higa University of Bonn, Germany Coulomb interactions within Halo EFT Rare exotic nuclei have recently drawn a lot of interest both from experimentalists and theorists, due to properties that challenge the theoretical knowledge gained from studies of stable nuclei. Particularly interesting is the formation of clusters and halo structures, whose small bindings lead to threshold phenomena with important consequences for nuclear astrophysics. In many cases the exitation energy of each cluster is much smaller than the binding among clusters, making them suitable systems for employing Effective Field Theory (EFT) techniques. Halo EFT has been developed and successfully applied to neutron-alpha scattering [1,2], with a proper account on the P_{3/2} resonance around 1

Alvin Kiswandhi Alvin Kiswandhi Flarida State University A model for $\pi \eta$ photoproduction We describe a model of $\pi \eta N$ photoproduction based on a phenomenological Lagrangian approach that satisfies two-body unitary and is relativistic. Unitarity is ensured by using the Lippmann-Schwinger equation to iterate the vertices and dress the propagators to all orders, and by including all possible two-body and quasi-two-body intermediate channels. This model has been tested by investigating $\pi \pi N$ photoproduction. A preliminary comparison of our calculation to an existing $\pi \pi N$ photoproduction study is made, and is shown to produce consistent results. We have also calculated the sum of the nonresonant Born diagrams in $\pi \eta N$ photoproduction and compared the resulting observables to invariant

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

Pierre Capel Pierre Capel Michigan State University Theoretical description of breakup reactions of halo nuclei Since their discovery in the mid-80's halo nuclei have attracted many theoretical and experimental studies. These nuclei indeed exhibit a very peculiar structure: they can be seen as a core containing most of the nucleons to which one or two neutrons are loosely bound. These valence neutrons have a high probability of presence at large distances from the other nucleons, and form a sort of halo around the core. Due to their short lifetime, these nuclei cannot be studied with usual spectroscopic techniques, and one must resort to indirect methods like breakup reactions. In these reactions, the core-halo structure dissociates through interaction with a target. The extraction of reliable structure information from these

The lack of arbitrage drives markets toward equilibria and provides exact prices for stock options and futures; modern finance uses the notion of "risk-neutral probability measures," but one may also employ quantum mechanical time evolution with non-Hermitian Hamiltonians or path integral methods to accomplish this.

Florida State University Florida State University Some Aspects of Semileptonic Decay of Baryons in a Quark Model We discuss some aspects of semileptonic decays of baryons. We calculate semileptonic baryon form factors in a quark model and compare our results with the predictions of HQET at leading order for both heavy to heavy and heavy to light decays. We also examine decays to excited states, as experimental measurements at CLEO assume that the decays to the ground state saturate the Lambda_c decay. Our results indicate that the branching ratio for decays to excited Lambda is not insignificant, in contradiction to the CLEO assumption. We have also calculated the rate for Lambda_b to Lambda_c decays. All our calculations have been done using two different bases for the wave function, harmonic oscillator and the sturmian wave

Los Alamos National Laboratory Los Alamos National Laboratory University of Illinois Pairing in neutron matter and in cold atomic systems The equation of state and pairing gap of neutron matter at low densities are important to the structure and cooling of neutron stars, and potentially to the surface properties of neutron-rich nuclei. Cold fermionic gases provide another setting with quite similar physics. Both these systems are very strongly paired, i.e. the pairing gap is of the order of the Fermi energy. Several many-body schemes have been devised in an attempt to accurately describe the strong coupling regime. In this talk, I will discuss recent results on the equation of state, the pairing gap, and other observables that we have calculated using a microscopic ab initio method. I will also mention some even more recent results on Fermi-Fermi

A superposition of several entropy-components (S) with model-inherent weighting results in an excellent reproduction of the overall Solar System (SS) isotopic r-process residuals, as well as the more recent observations of elemental abundances of metal-poor, r-process-rich halo-stars in the early Galaxy. For the heavy r-process elements beyond Sn, our HEW model

Pawel Danielewicz Pawel Danielewicz National Superconducting Cyclotron Laboratory, Michigan State University Bulk Nuclear Properties from Central Reactions Determination of bulk nuclear properties using central reactions of heavy nuclei is reviewed. Different observables need to be searched for testing different bulk properties. In particular, the stopping observables, such as limiting momentum transfer or anisotropy of particle rapidity distribution, are found to be correlated with nuclear viscosity. The systematics of the latter is now of interest in the context of claims of detecting the perfect liquid at RHIC. The momentum dependence of anisotropies of proton emission, associated with the reaction plane, is found to be correlated, in the transport simulations of central collisions, to the momentum dependence of
