    In this paper we build up a canonical vintage capital model with embodied and disembodied technical progress and generalized Nash bargaining in the labor market. First, we handle both types of technical progress as exogenous, but we endogenize them after. In these setups, we comprehensively study the relations between technical progress, unemployment, and job creation and destruction in the short and long run.

  2. Heterogeneous catalytic process for alcohol fuels from syngas. Quarterly technical progress report No. 8, October--December 1993

    The novel heterogeneous catalysts for conversion of syngas to oxygenates having use as fuel enhancers, to explore novel reactor and process concepts applicable in this process, and to develop the best total process for converting syngas to liquid fuels. Our current targets for isobutanol-producing catalysts are to produce an equimolar mixture of methanol and isobutanol with a productivity for isobutanol of > 50 g/Kg-hr. Reactor system modifications, undertaken to improve data quality, have been completed. The changes should help eliminate differences between the two reactors and allow for more accurate determination of higher molecular weight products. To calibrate our new reactor system, we have retested our ``best`` isobutanol catalyst, 10-DAN-54 (a promoted Zn/Cr/Mn spinel oxide). Under standard test conditions (400{degrees}C, 1000 psi, 12000 GHSV and syngas ratio = 1:1), this catalyst produces 200--252 g/kg-hr of total alcohols (total alcohol selectivities of 57--68%) with an isobutanol rate of 94--130 g/kg-hr and a MeOH/i-BuOH product mole ratio of 3. These results compare with a productivity of 112 g/kg-hr of total alcohols (total alcohol selectivity of 86%) with an isobutanol rate of 38 g/kg-hr and a MeOH/i-BuOH product mole ratio of 3 observed in the original microreactor system configuration. It should be remembered that the test apparatus is designed for screening only. Detailed, more reliable data for kinetic modeling must be generated using larger catalyst charges (> 10g) and in larger scale test equipment.

    The principal objectives of this project are to discover and evaluate novel heterogeneous catalysts for conversion of syngas to oxygenates having use as fuel enhancers, to explore novel reactor and process concepts applicable in this process, and to develop the best total process for converting syngas to liquid fuels. The project is being pursued as two concurrent tasks. Task I involves catalyst research and development and is being largely conducted by catalyst chemists and analytical specialists. Task 2 is largely an engineering activity, and includes process conceptualization and economics and bench-scale process evaluation of systems developed in Task 1. The current goal of the catalyst development program is to increase selectivities to oxygenates to greater than 90% with methanol making up less than 70% of the oxygenates, increase rates to 20 lb/ft{sup 3}/hr, and have conversions of greater than 20%. Earlier work in this organization has shown that a potassium-modified Zn-Or-Mn-0 based catalyst system had alcohol selectivities as high as 70-80 wt %, but the overall alcohol yield was only 11 lb/ft{sup 3}/hr. The effects of the precipitation pH on surface area, porosity, and thermal characteristics of the mixed metal oxide component were examined. A designed experiment showed that the precipitation pH was an important factor influencing the BET surface area, and the calcination temperature had a negative effect on the surface area as expected. The optimal surface area for a given calcination temperature would be achieved at a pH of around 10.2. Other interesting results from the models were that calcination time did not affect any of the physical properties measured and only calcination temperature affected the mean pore diameter of the solid.

    The last issue of the Alcohol Fuels Process R/D Newsletter contained a work breakdown structure (WBS) of the SERI Alcohol Fuels Program that stressed the subcontracted portion of the program and discussed the SERI biotechnology in-house program. This issue shows the WBS for the in-house programs and contains highlights for the remaining in-house tasks, that is, methanol production research, alcohol utilization research, and membrane research. The methanol production research activity consists of two elements: development of a pressurized oxygen gasifier and synthesis of catalytic materials to more efficiently convert synthesis gas to methanol and higher alcohols. A report is included (Finegold et al. 1981) that details the experimental apparatus and recent results obtained from the gasifier. The catalysis research is principally directed toward producing novel organometallic compounds for use as a homogeneous catalyst. The utilization research is directed toward the development of novel engine systems that use pure alcohol for fuel. Reforming methanol and ethanol catalytically to produce H/sub 2/ and CO gas for use as a fuel offers performance and efficiency advantages over burning alcohol directly as fuel in an engine. An application of this approach is also detailed at the end of this section. Another area of utilization is the use of fuel cells in transportation. In-house researchers investigating alternate electrolyte systems are exploring the direct and indirect use of alcohols in fuel cells. A workshop is being organized to explore potential applications of fuel cells in the transportation sector. The membrane research group is equipping to evaluate alcohol/water separation membranes and is also establishing cost estimation and energy utilization figures for use in alcohol plant design.

    The alcohol fuels program consists of in-house and subcontracted research for the conversion of lignocellulosic biomass into fuel alcohols via thermoconversion and bioconversion technologies. In the thermoconversion area, the SERI gasifier has been operated on a one-ton per day scale and produces a clean, medium-Btu gas that can be used to manufacture methanol with a relatively small gas-water shift reaction requirement. Recent research has produced catalysts that make methanol and a mixture of higher alcohols from the biomass-derived synthetic gas. Three hydrolysis processes have emerged as candidates for more focused research. They are: a high-temperature, dilute-acid, plug-flow approach based on the Dartmouth reactor; steam explosion pretreatment followed by hydrolysis using the RUT-C30 fungal organism; and direct microbial conversion of the cellulose to ethanol using bacteria in a single or mixed culture. Modeling studies, including parametric and sensitivity analyses, have recently been completed. The results of these studies will lead to a better definition of the present state-of-the-art for these processes and provide a framework for establishing the research and process engineering issues that still need resolution. In addition to these modeling studies, economic feasibility studies are being carried out by commercial engineering firms. Their results will supplement and add commercial validity to the program results. The feasibility contractors will provide input at two levels: Technical and economic assessment of the current state-of-the-art in alcohol production from lignocellulosic biomass via thermoconversion to produce methanol and higher alcohol mixtures and bioconversion to produce ethanol; and identification of research areas having the potential to significantly reduce the cost of production of alcohols.

    Improving patient compliance with physicians’ treatment or prescription recommendations is an important goal in medical practice. We examine the relationship between treatment progress and patient compliance. We hypothesize that patients balance expected benefits and costs during a treatment episode when deciding on compliance; a patient is more likely to comply if doing so results in an expected gain in health benefit.

    Results are reported on the effect of ethanol on the oxidation of ferrocytochrome c by ferricyanide and its cumulative effect with pH and temperature, on structure and spectra of cytochrome c. It is concluded that low concentrations of alcohols which do not change dramatically the structure and physical properties of cytochrome c, but produce changes in the structure of water, cause small changes in the structure of the protein. This is manifested by the shift in the pKa, and also in the retardation of the redox reactions. This indicates that water molecules participate in the reaction complex of cytochrome c with its redox substrates. (DLC)

    Copper and cobalt are the key elements in syngas conversion catalyst systems used for higher alcohol synthesis. Their proximity and synergy sensitively control the selectivity and efficiency of the process. It is believed that their outer electronic charge distribution which is responsible for their electrical and magnetic properties might be governing their catalytic properties also. To examine the correlation between catalytic and magnetic properties, a series of copper cobalt catalysts (Co/Cu ratio 5:1 to 5:5) with and without a support were prepared. The nuclear quadrupole resonance spectrum of copper and (zero-field) nuclear magnetic resonance spectrum of cobalt and magnetization and hysteresis character of the catalyst were analyzed. Similar to the catalytic results, the magnetic results also were found to be very sensitive to the preparation technique. The results indicate possible electron exchange between copper and cobalt, and cobalt and the support Titania.

  13. Liver proteomics in progressive alcoholic steatosis

    International Nuclear Information System (INIS)

    Fatty liver is an early stage of alcoholic and nonalcoholic liver disease (ALD and NALD) that progresses to steatohepatitis and other irreversible conditions. In this study, we identified proteins that were differentially expressed in the livers of rats fed 5% ethanol in a Lieber–DeCarli diet daily for 1 and 3 months by discovery proteomics (two-dimensional gel electrophoresis and mass spectrometry) and non-parametric modeling (Multivariate Adaptive Regression Splines). Hepatic fatty infiltration was significantly higher in ethanol-fed animals as compared to controls, and more pronounced at 3 months of ethanol feeding. Discovery proteomics identified changes in the expression of proteins involved in alcohol, lipid, and amino acid metabolism after ethanol feeding. At 1 and 3 months, 12 and 15 different proteins were differentially expressed. Of the identified proteins, down regulation of alcohol dehydrogenase (− 1.6) at 1 month and up regulation of aldehyde dehydrogenase (2.1) at 3 months could be a protective/adaptive mechanism against ethanol toxicity. In addition, betaine-homocysteine S-methyltransferase 2 a protein responsible for methionine metabolism and previously implicated in fatty liver development was significantly up regulated (1.4) at ethanol-induced fatty liver stage (1 month) while peroxiredoxin-1 was down regulated (− 1.5) at late fatty liver stage (3 months). Nonparametric analysis of the protein spots yielded fewer proteins and narrowed the list of possible markers and identified D-dopachrome tautomerase (− 1.7, at 3 months) as a possible marker for ethanol-induced early steatohepatitis. The observed differential regulation of proteins have potential to serve as biomarker signature for the detection of steatosis and its progression to steatohepatitis once validated in plasma/serum. -- Graphical abstract: The figure shows the Hierarchial cluster analysis of differentially expressed protein spots obtained after ethanol feeding for 1 (1–3

The second purpose is to expand upon it by distinguishing  between the different types of technical progress. Finally, the third purpose is to comment on Labini’s comparison of Ricardo and Keynes on the possibility of technological unemployment. Regarding his description of technological progress as “labour saving”, the author shows that a more comprehensive description would be more useful for his purposes.

    This paper considers the technical progress in offshore pipeline construction with limitation to some general subjects covering pipeline design, installation and start-up. In future the use of limit state pipeline design philosophy, may be implemented as an alternative to the stress based design commonly used to day giving a potential for further optimisation of the pipeline design and consequently reduction of the initial investment. Comprehensive research and development efforts in Norway in the second half of the 1970`s, made it technically feasible to cross the deep water Norwegian Trench in the 1980`s. In addition, the development of several offshore pipeline systems until to day including gas distribution systems to the European continent, have brought Norway to the forefront of technical expertise

  19. Technical progress and its strategic consequences

    International Nuclear Information System (INIS)

    The history of energy during recent decades has shown that technical progress can have consequences for the organisation of markets, company strategies and the economy in general, confounding all forecasts and going beyond simple technical change. As a consequence for example, improvements in the techniques concerning the exploration and production of hydrocarbons have led to the petrol 'counter-crisis', the reduction in the power of OPEC and undreamed of gains in wealth for certain countries. The progress in gas turbines has led to the reversal of the age-old tendency towards increases in the size of electricity production units and encouraged the liberation of this sector. When looking at the future it is therefore judicious to try and understand the forces at work, and the major trends which result. This is the aim of the articles in this edition of the Revue de l'Energie, published on the occasion of the European colloquium on 'Technical progress faced with the challenges of the energy sector in the future' organised by the Association of Energy Economists.

    This project was divided into two parts. One part evaluated possible catalysts for producing higher-alcohols (C(sub 2) to C(sub 5+)) as fuel additives. The other part provided guidance by looking both at the economics of mixed-alcohol production from coal-derived syngas and the effect of higher alcohol addition on gasoline octane and engine performance. The catalysts studied for higher-alcohol synthesis were molybdenum sulfides promoted with potassium. The best catalysts produced alcohols at a rate of 200 g/kg of catalyst/h. Higher-alcohol selectivity was over 40%. The hydrocarbon by-product was less than 20%. These catalysts met established success criteria. The economics for mixed alcohols produced from coal were poor compared to mixed alcohols produced from natural gas. Syngas from natural gas was always less expensive than syngas from coal. Engine tests showed that mixed alcohols added to gasoline significantly improved fuel quality. Mixed-alcohols as produced by our catalysts enhanced gasoline octane and decreased engine emissions. Mixed-alcohol addition gave better results than adding individual alcohols as had been done in the 1980's when some refiners added methanol or ethanol to gasoline

  2. Sludge Treatment Evaluation: 1992 Technical progress

    International Nuclear Information System (INIS)

    This report documents Fiscal Year 1992 technical progress on the Sludge Treatment Evaluation Task, which is being conducted by Pacific Northwest Laboratory. The objective of this task is to develop a capability to predict the performance of pretreatment processes for mixed radioactive and hazardous waste stored at Hanford and other US Department of Energy (DOE) sites. Significant cost savings can be achieved if radionuclides and other undesirable constituents can be effectively separated from the bulk waste prior to final treatment and disposal. This work is initially focused on chemical equilibrium prediction of water washing and acid or base dissolution of Hanford single-shell tank (SST) sludges, but may also be applied to other steps in pretreatment processes or to other wastes. Although SST wastes contain many chemical species, there are relatively few constituents -- Na, Al, NO3, NO2, PO4, SO4, and F -- contained in the majority of the waste. These constituents comprise 86% and 74% of samples from B-110 and U-110 SSTS, respectively. The major radionuclides of interest (Cs, Sr, Tc, U) are present in the sludge in small molal quantities. For these constituents, and other important components that are present in small molal quantities, the specific ion-interaction terms used in the Pitzer or NRTL equations may be assumed to be zero for a first approximation. Model development can also be accelerated by considering only the acid or base conditions that apply for the key pretreatment steps. This significantly reduces the number of chemical species and chemical reactions that need to be considered. Therefore, significant progress can be made by developing all the specific ion interactions for a base model and an acid dissolution model

  8. Technical progress and its factors in Russia’s economy

    Directory of Open Access Journals (Sweden)

    Simon György Jr.

    2010-01-01

    Full Text Available In this paper long-term growth in Russia’s economy is viewed in the context of technical progress, based on both neoclassical and endogenous theories. The dynamics of economic growth with some aspects of catch-up development are examined, as well as capital deepening. TFP is quantified in terms of both output and productivity increases to reveal the leading role of embodied technical progress in productivity growth. An endogenous growth model helped to discern three complex factors of technical progress in the Russian economy, to which at the macro level a factor related to natural wealth (oil and gas resources was added. This enabled the author to conclude that the most important macroeconomic factor of Russia’s technical progress in the half century from the early 1960s to the late 2000s was its immobile component. At the manufacturing level the situation was more complicated, as the initial leadership of creative technical progress was superseded by the dominance of the mobile factor. The collapse of the Soviet Union made the Russian economy more service-oriented and radically changed the conditions of economic modernization, in which technology transfer ensured by FDI began to play a more prominent part, particularly after the default of 1998.

The discovery of the fundamental possibility of using the energy released by the chain reactions associated with fission of heavy nuclei and fusion of light nuclei was a stupendous gift of science. The full significance of these revelations will appear later, at the end of this century, but it is already clear that the widespread use of nuclear energy from fission and fusion is inevitable, as the only technically and economically satisfactory way of overcoming the shortage of cheap fuels such as oil and gas. The large-scale development of atomic power engineering for various purposes - electric power, process heat and district heating, heat and power supplies for the metallurgical industry, power and heat for different branches of the chemical industry and radiation stimulation of chemical products - will help to save oil and gas so that they can be used for purposes where they are most difficult to replace

    Background: Chronic liver injury can lead to the development of liver fibrosis and cirrhosis but only in a minority of patients. Currently, it is not clear which factors determine progression to fibrosis. We investigated whether DNA\\methylation profile as determined by pyrosequencing can distinguish patients with mild from those with advanced/severe fibrosis in non-alcoholic liver disease (NAFLD) and alcoholic liver disease (ALD). To this end, paraffin-embedded liverbiopsies were collected fr...

  14. Research progress of fabricating polyvinyl alcohol coating on plastic microsphere

    International Nuclear Information System (INIS)

    In the procedures of designing polystyrene-polyvinyl alcohol-CH (carbon and hydrogen elements) (PS-PVA-CH) triple-layer microspheres, there are many methods such as drop-tower technique, emulsion micro-encapsulation, dip (spin) coating, interfacial polycondensation, and spraying technique to prepare the PVA coating. Drop-tower technique, emulsion micro-encapsulation and dip (spin) coating are most-commonly used. The advantages, disadvantages and the research progress of the three methods are summarized in this paper. Emulsion micro-encapsulation is suitable for preparing double-layer microspheres of sizes smaller then 500 μm, with high survival ratio and good quality. However, the preparation process is easily influenced by artificial factors. Small-sized double-layer microspheres can also be prepared by the drop-tower technique, and the preparation period is short. But there are still some problems such as the difficulty in designing the droplet generator, uneven PVA coating and the difficulty in preparing large-sized microspheres. Dip (spin) coating technique can be used to prepare PS-PVA microspheres with sizes larger than 1000 μm, but the spread of PVA coating is affected by many factors in this method, and the prepared PVA coating is too thin and not uniform.

    Full Text Available Wireless capsule endoscopy (WCE offers a feasible noninvasive way to detect the whole gastrointestinal (GI tract and revolutionizes the diagnosis technology. However, compared with wired endoscopies, the limited working time, the low frame rate, and the low image resolution limit the wider application. The progress of this new technology is reviewed in this paper, and the evolution tendencies are analyzed to be high image resolution, high frame rate, and long working time. Unfortunately, the power supply of capsule endoscope (CE is the bottleneck. Wireless power transmission (WPT is the promising solution to this problem, but is also the technical challenge. Active CE is another tendency and will be the next geneion of the WCE. Nevertheless, it will not come true shortly, unless the practical locomotion mechanism of the active CE in GI tract is achieved. The locomotion mechanism is the other technical challenge, besides the challenge of WPT. The progress about the WPT and the active capsule technology is reviewed.

    I develop a theory of technical progress that uncovers sufficient conditions for opposition to the adoption of child labor laws to disappear over time. The supply of child labor comes exclusively from unskilled parents, because of their inability to help their children benefit from formal education, while its demand originates from capitalists-the firms' owners. Because child labor crowds out adult employment, there are always social pressures to ban it. However, such pressures are met by cap...

    The onset of alcoholic liver disease (ALD) is initiated by different cell types in the liver and a number of different factors including: products derived from ethanol- induced inflammation, ethanol metabolites, and the indirect reactions from those metabolites. Ethanol oxidation results in the production of metabolites that have been shown to bind and form protein adducts,and to increase inflammatory, fibrotic and cirrhotic responses. Lipopolysaccharide (LPS) has many deleterious effects and plays a significant role in a number of disease processes by increasing inflammatory cytokine release. In ALD, LPS is thought to be derived from a breakdown in the intestinal wall enabling LPS from resident gut bacterial cell walls to leak into the blood stream. The ability of adducts and LPS to independently stimulate the various cells of the liver provides for a two-hit mechanism by which various biological responses are induced and result in liver injury. Therefore,the purpose of this article is to evaluate the effects of a two-hit combination of ethanol metabolites and LPS on the cells of the liver to increase inflammation inflammation and fibrosis, and play a role in the development and/or progression of ALD.

    The International Linear Collider: A Technical Progress Report marks the halfway point towards the Global Design Effort fulfilling its mandate to follow up the ILC Reference Design Report with a more optimised Technical Design Report (TDR) by the end of 2012. The TDR will be based on much of the work reported here and will contain all the elements needed to propose the ILC to collaborating governments, including a technical design and implementation plan that are realistic and have been better optimised for performance, cost and risk. We are on track to develop detailed plans for the ILC, such that once results from the Large Hadron Collider (LHC) at CERN establish the main science goals and parameters of the next machine, we will be in good position to make a strong proposal for this new major global project in particle physics. The two overriding issues for the ILC R&D programme are to demonstrate that the technical requirements for the accelerator are achievable with practical technologies, and that the ambitious physics goals can be addressed by realistic ILC detectors. This GDE interim report documents the impressive progress on the accelerator technologies that can make the ILC a reality. It highlights results of the technological demonstrations that are giving the community increased confidence that we will be ready to proceed with an ILC project following the TDR. The companion detector and physics report document likewise demonstrates how detector designs can meet the ambitious and detailed physics goals set out by the ILC Steering Committee. LHC results will likely affect the requirements for the machine design and the detectors, and we are monitoring that very closely, intending to adapt our design as those results become available.

    Full Text Available Objective: Understand the effect of chronic alcohol on the progression of periodontitis induced in Fischer-344 rats.Methods: For the study, 22 Fischer-344 rats, two months old were used, divided into groups: alcohol (n=8, ligature (n=7 and control (n=7. On the first day, the animals in the alcohol group were exposed to ingestion of a water solution containing 20% alcohol (size/size, up to day 90. After thirty days from the beginning of the experiment, the animals in the alcohol group and the ligature group were submitted to the placement of a silk thread around the right maxillary second molar. Nothing was performed on the left side, serving as control. All the groups were submitted to euthanasia 60 days after ligature placement. To assess the destruction of periodontitis, a radiographic exam was used to measure the destruction of bone height. Results: The results of the study showed that on the side in which periodontitis was induced, the group that ingested alcohol suffered an increase in destruction, with statistical differences when compared with the ligature and control groups and increased bone destruction in the ligature group when compared to control. Conclusion: Within the limitations of the study, it was concluded that chronic alcohol consumption by Fischer-344 rats led to greater progression of induced periodontitis.

  5. Theoretical particle physics: Technical progress report, May 1987-May 1988

    International Nuclear Information System (INIS)

    This Technical Progress Report outlines the research of the Task B High Energy Theory Group at Indiana University during 1987-88. We have been active in a variety of areas/emdash/superstrings, lattice gauge theory, quarkonium and neutrino physics. The following pages provide brief summaries of the progress we were able to make in these areas during the past year. In superstring theory, rules were developed for calculating string amplitudes to the one loop level for a wide variety of topologies; the stability of the string vacuum was investiagted for bosonic strings. We continued our mathematical studies of supergroups. In lattice gauge theory, we have been particularly interested in calculating, from first principles, QCD effects on weak interaction processes (of special interest here is the search for a better understanding of the mysterious /DELTA/I = /1/2/ rule). At the same time, we have been trying to develop more efficient algorithms to reduce the amount of computing necessary in lattice calculations. In more phenomenological work, we have been studying various aspects of bound quark-antiquark systems, including a new wave equation which incorporates relativitic kinematics. We have also been trying to find ways of experimentally distinguishing between Dirac and Majorana neutrinos

    2006-10-04

    The steel industry in the United States generates about 30 million tons of by-products each year, including 6 million tons of desulfurization and BOF/BOP slag. The recycling of BF (blast furnace) slag has made significant progress in past years with much of the material being utilized as construction aggregate and in cementitious applications. However, the recycling of desulfurization and BOF/BOP slags still faces many technical, economic, and environmental challenges. Previous efforts have focused on in-plant recycling of the by-products, achieving only limited success. As a result, large amounts of by-products of various qualities have been stockpiled at steel mills or disposed into landfills. After more than 50 years of stockpiling and landfilling, available mill site space has diminished and environmental constraints have increased. The prospect of conventionally landfilling of the material is a high cost option, a waste of true national resources, and an eternal material liability issue. The research effort has demonstrated that major inroads have been made in establishing the viability of recycling and reuse of the steelmaking slags. The research identified key components in the slags, developed technologies to separate the iron units and produce marketable products from the separation processes. Three products are generated from the technology developed in this research, including a high grade iron product containing about 90%Fe, a medium grade iron product containing about 60% Fe, and a low grade iron product containing less than 10% Fe. The high grade iron product contains primarily metallic iron and can be marketed as a replacement of pig iron or DRI (Direct Reduced Iron) for steel mills. The medium grade iron product contains both iron oxide and metallic iron and can be utilized as a substitute for the iron ore in the blast furnace. The low grade iron product is rich in calcium, magnesium and iron oxides and silicates. It has a sufficient lime value and

    Full Text Available In this paper, taking construction project as the research object, the relationship between the project maturity index calculated by the construction project technical risks with different fine degree and the project progress index is studied, and the equilibrium relationship between the Party A’s utility curve and the Party B’s cost curve of using project maturity index and project progress index as the research variables is analyzed. The results show that, when the construction project technical risk division is more precise, the conjoint utility of the project's technical maturity index and the project progress is higher, and the project’s Party A and Party B two sides are closer to the optimal equilibrium. This shows that the construction project technical risk must be finely divided, and managed and controlled respectively, which will help to improve the conjoint utility of the project Party A and Party B two sides.

    The rebound effects of technological advancement on energy consumption make it very complicated to measure the impact of technological advancement on energy efficiency.This article,taking 35 industries as samples,utilizes the non-parameter DEA-Malmquist productivity approach to subcategorise technological advancement into three parts:science-technological(sci-tech)progress,pure technical efficiency and efficiency of scale.The panel technique is then used to work out each subcategory’s contribution to energy efficiency individually.Findings show that technological efficiency (calculated by multiplying the results of pure technical efficiency and scale efficiency)is the principal factor in the improvement of energy efficiency while the contribution from sci-tech progress is comparatively less.Overtime,however,the effect of sci-tech progress is gradually heightened while the effect of technical efficiency slowly diminishes.

    The VLA Sky Survey (VLASS) was initiated to exploit the science and technical opportunities for a new large radio astronomical survey using the Karl G. Jansky Very Large Array. In March 2015, the proposal for the VLASS underwent a formal Community Review. What emerged from this review is a 5400 hour project to survey the 33885 square degrees of the sky above Declination -40 degrees from 2-4 GHz at 2MHz frequency resolution and 2.5" angular resolution. Over the survey duration of 7 years, each area of the sky will be covered in 3 epochs spaced 32 months apart, to a depth of 0.12mJy/beam rms noise per epoch (0.07mJy/beam combined) in total intensity (Stokes I) and including full polarization. Observations are planned to commence in mid-2016. The raw data will be available in the NRAO archive immediately with no proprietary period and science data products will be provided to the community in a timely manner.In this presentation we describe the survey design and the Technical Implementation Plan (TIP) for the VLASS. The VLASS Basic Data Products (BDP) that will be produced by the survey team include: raw and calibrated visibility data, quick-look continuum images, single-epoch images and spectral image cubes, single-epoch basic object catalogs, and cumulative "static sky" images and image cubes and basic object catalogs to the full survey depth. Calibration, image processing, and analysis for the VLASS will be carried out through automated pipelines being developed at NRAO. Integral to this workflow is maintaining Quality Assurance throughout the system from telescope to archive. The storage and archive services budgeted for the BDP is 1PB for the data and images combined. Significantly higher storage would be required to serve the highest spectral resolution spectral cubes over the full sky area, and thus devising an affordable strategy for providing these services is critical, for example through "Processing on Demand" based on user query of the archive. We will

    Progress during the 12-month period, October 1, 1980 to September 30, 1981 on the University of Wisconsin Plasma Physics contract is described. Most of the work centers around two major experimental devices, the Levitated Octupole and Tokapole II. A major upgrade of the Octupole is underway to include 2 MW of ICRH and 1.8 MW of neutral beam heating. Meanwhile, gun optimization and low field operation has resulted in the attainment of 35% beta, a factor of 9 above the single fluid ballooning limit. The ICRH experiment is well underway, and the first neutral beam source has been installed. The Tokapole is operating reliably at the full design field of 10 kG with 12 msec discharges. Low q (approx. 0.4) discharges with flat current profiles are obtained at reduced (approx. 3kG) toroidal field. The device is presently being used to study shear Alfven wave heating, ECRH startup, poloidal ohmic heating, and plasma transport

    1995-08-01

    In the year just past, the authors made major progress in understanding turbulence and transport in both core and edge. Development of the capability for turbulence measurements throughout the poloidal cross section and intelligent consideration of the observed asymmetries, played a critical role in this work. In their confinement studies, a limited plasma with strong, H-mode-like characteristics serendipitously appeared and received extensive study though a diverted H-mode remains elusive. In the plasma edge, they appear to be close to isolating a turbulence drive mechanism. These are major advances of benefit to the community at large, and they followed from incremental improvements in diagnostics, in the interpretation of the diagnostics, and in TEXT itself. Their general philosophy is that the understanding of plasma physics must be part of any intelligent fusion program, and that basic experimental research is the most important part of any such program. The work here demonstrates a continuing dedication to the problems of plasma transport which continue to plague the community and are an impediment to the design of future devices. They expect to show here that they approach this problem consistently, systematically, and effectively.

    Scientific and technical progress has been the driving forces of enterprises development. Milk productive enterprises are developing faster and growing better. It is very important to measure the contributive ratio of scientific and technical progress in milk productive enterprises. And the appraisement could help to develop milk productive enterprises. The model C2GS2 was established to appraise the contributive ratio of scientific and technical progress in milk productive enterprises in the research. And the appraisement on the contributive ratio of scientific and technical progress in milk productive enterprises was made by the model. In the results of appraisement, science and technology play a main role in milk productive enterprises. It is shown that our milk productive enterprises are developed by scientific and technical progress while not by input of productive factors.

    About every 12 years, asphalt roads must be reworked, and this is usually done by placing thick layers (hot-mix overlays) of new material on top of failed material, resulting in considerable waste of material and use of new asphalt binder. A good recycling agent is needed, not only to reduce the viscosity of the aged material but also to restore compatibility. Objective is to establish the technical feasibility (Phase I) of determining the specifications and operating parameters for producing high quality recycling agents which will allow most/all the old asphalt-based road material to be recycled. It is expected that supercritical fractionation can be used. The advanced road aging simulation procedure will be used to study aging of blends of old asphalt and recycling agents.

    The Department of Energy recently began the operation of its Mining Equipment Test Facility. One component at that facility is the highly sophisticated Mine Roof Simulator (MRS) for research and development of roof support equipment. Because of its previous experience, the University of Pittsburgh was contracted to assist the Facilities Manager by providing professional technical support services, principally for the MRS. This technical progress report briefly describes the services provided during the reporting period and planned for the next period. No significant technical disclosures of interest to those not associated with the MRS are contained herein. One of the four units of the US government-owned METF is the Mine Roof Simulator. This unique $10 million test facility was designed to simulate underground mine roof loads and motions. The MRS is a hybrid, analog-digital, computer-controlled, closed-loop, electro-hydraulic, research device capable of applying either loads or displacements in the vertical and one horizontal axis. Its vertical capacity of 3,000,000 pounds can be applied over its 20 by 20 foot active test area. The horizontal load capacity is 1,600,000 pounds. It can simulate coal seam heights of up to 16 feet. Automatic data acquisition and real time display are provided. The most modern, sophisticated technology was used in its design and construction.

    About 27 million tons of asphalt and nearly twenty times this much aggregate are consumed each year to build and maintain over two million miles of roads in this country. Over a cycle of about 12 years on the average, these roads must be reworked and much of these millions of tons of rock and asphalt cannot be reused with present recycling technology. Instead, much of the maintenance is accomplished by placing thick layers (hot-mix overlays) of new material on top of the failed material. This results in considerable waste of material, both in terms of quality aggregate and in terms of asphalt binder. In addition, the new asphalt binder represents a significant source of potential energy. The main impediment to recycling asphalt binder is the poorly developed science of recycling agent composition and, as a result, optimum recycling agents are not available. An excellent recycling agent should not only be able to reduce the viscosity of the aged material, but it must also be able to restore compatibility. The properties of the old material and recycling agent must be compatible to give both good initial properties and aging characteristics, and this must be understood. The agent must also be inexpensive and easily manufactured. A large quantity of potential feedstock for the production of recycling agents is available and much of it is now fed to cokers. This material could be recovered by supercritical extraction which is an existing refinery technology. A supercritical pilot plant is available at Texas A&M and has been used to produce fractions for study. The objective of this research is to establish the technical feasibility of determining the specifications and operating parameters necessary to produce high quality recycling agents which will allow most old asphalt-based road material to be recycled.

    2004-01-01

    Czech Republic joined European action plan on alcohol for years 2000 to 2004 and signed its accomplishment. However, since 2000 situation has worsened. Alcohol consumption raised in 2001 (the last known data) to 10.0 litters of 100% alcohol (that is 159.9 litters of beer, 8.2 litters of distillates and 16.2 litters of wine per person per year). The only positive aspect was the small rise of consumption tax in distillates and that some thesis of the European action plan on alcohol were included into the governmental document "Long-term improvement of the health status of the population in Czech republic--Health for everybody in the 21st century". The proclamation has had no practical effect. Highly adverse is the situation with alcohol consumption in children and adolescents, which was described in the last study. Risks related to the high alcohol consumption in Czech republic include: High incidence of alcohol related death, including children, adolescents and young people (injuries, traffic accidents, poisonings, suicides, liver and tumor diseases); higher morbidity; lower productivity at work and worse position of Czech workers in concurrent environment; worse reproduction health, higher incidence of inborn defects caused by alcohol taken during pregnancy (including its beginning, when women do not know it); frequent social and family problems caused by alcohol abuses; increased risk of consumption of non-alcoholic drugs in children and adolescents. Alcohol belong to throughway drugs and its consumption in early age represents for children and adolescents a risk factor for other addictive drugs; alcohol is related namely to violent and negligent delicts; flagrant alcohol excesses together with alcohol related criminality harm the prestige of Czech Republic to foreign visitors and can drive them back.

    Full Text Available Abstract Background Most people being treated for alcoholism are unable to successfully quit drinking within their treatment programs. In few cases do we know the full picture of how abstinence is achieved in Taiwan. We tracked processes of abstinence in alcohol-dependency disorders, based on study evidence and results. This research explores the process of recovery from the viewpoint of the alcohol-dependent. Methods Semi-structured interviews were conducted in two different settings, using purpose sampling, during 2003-2004. The data were analyzed using content analysis. Participants were 32 adults, purposefully selected from an Alcoholics Anonymous group and a psychiatric hospital in North Taiwan. Results We found that the abstinence process is an ongoing process, in which the alcohol-dependent free themselves of addiction progressively. This process never ends or resolves in complete recovery. We have identified three stages in the struggle against alcoholism: the Indulgence, Ambivalence and Attempt (IAA cycle, in which the sufferer is trapped in a cycle of attempting to give up and failing; the Turning Point, in which a Personal Nadir is reached, and the Ongoing Process of abstinence, in which a constant effort is made to remain sober through willpower and with the help of support groups. We also discuss Influencing Factors that can derail abstinence attempts, pushing the sufferer back into the IAA cycle. Conclusion This study provides important points of reference for alcohol and drug service workers and community healthcare professionals in Taiwan, casting light on the abstinence process and providing a basis for intervention or rehabilitation services.

    Alcoholic hallucinosis is a rare complication of chronic alcohol abuse characterized by predominantly auditory hallucinations that occur either during or after a period of heavy alcohol consumption. Bleuler (1916) termed the condition as alcohol hallucinosis and differentiated it from Delirium Tremens. Usually it presents with acoustic verbal hallucinations, delusions and mood disturbances arising in clear consciousness and sometimes may progress to a chronic form mimicking schizophrenia. One such case with multimodal hallucinations in a Defence Service Corps soldier is presented here. PMID:24250051

    1991-12-31

    In September of 1989 work began on the DOE University Program grant DE-FG07-89ER12889. The grant provides support for a three year project to develop and demonstrate Intelligent Distributed Control (IDC) for Nuclear Power Plants. The body of this Second Annual Technical Progress report covers the period from September 1990 to September 1991. It summarizes the second year accomplishments while the appendices provide detailed information presented at conference meetings. These are two primary goals of this research. The first is to combine diagnostics and control to achieve a highly automated power plant as described by M.A. Schultz, a project consultant during the first year of the project. This philosophy, as presented in the first annual technical progress report, is to improve public perception of the safety of nuclear power plants by incorporating a high degree automation where greatly simplified operator control console minimizes the possibility of human error in power plant operations. A hierarchically distributed control system with automated responses to plant upset conditions is the focus of our research to achieve this goal. The second goal is to apply this research to develop a prototype demonstration on an actual power plant system, the EBR-II steam plant.

    Full Text Available The growing need to address current energy and environmental problems has sparked an interest in developing improved biological methods to produce liquid fuels from renewable sources. While microbial ethanol production is well established, higher chain alcohols possess chemical properties that are more similar to gasoline. Unfortunately, these alcohols (except 1-butanol are not produced efficiently in natural microorganisms, and thus economical production in industrial volumes remains a challenge. Synthetic biology, however, offers additional tools to engineer synthetic pathways in user-friendly hosts to help increase titers and productivity of these advanced biofuels. This review concentrates on recent developments in synthetic biology to produce higher-chain alcohols as viable renewable replacements for traditional fuel.

    Pulque is a traditional Mexican alcoholic beverage produced from the fermentation of the fresh sap known as aguamiel (mead) extracted from several species of Agave (maguey) plants that grow in the Central Mexico plateau. Currently, pulque is produced, sold and consumed in popular districts of Mexico City and rural areas. The fermented product is a milky white, viscous, and slightly acidic liquid beverage with an alcohol content between 4 and 7° GL and history of consumption that dates back to pre-Hispanic times. In this contribution, we review the traditional pulque production process, including the microbiota involved in the biochemical changes that take place during aguamiel fermentation. We discuss the historical relevance and the benefits of pulque consumption, its chemical and nutritional properties, including the health benefits associated with diverse lactic acid bacteria with probiotic potential isolated from the beverage. Finally, we describe the actual status of pulque production as well as the social, scientific and technological challenges faced to preserve and improve the production of this ancestral beverage and Mexican cultural heritage.

  6. Research and Test Reactor Conversion to Low Enriched Uranium Fuel: Technical and Programmatic Progress

    International Nuclear Information System (INIS)

    The U.S Department of Energy (DOE) initiated a program - the Reduced Enrichment for Research and Test Reactors (RERTR) - in 1978 to develop the technology necessary to reduce the use of High Enriched Uranium (HEU) fuel in research reactors by converting them to low enriched uranium (LEU) fuel. In 2004, the reactor conversion program became the driving pilar of the Global Threat Reduction Initiative (GTRI), a program established by the U.S. DOE's National Nuclear Security Administration. The overall GTRI objectives are the conversion, removal or protection of vunerable civilian radiological and nuclear material. As part of the GTRI, the Conversion Program has accelerated the schedules and plans for conversion of additional research reactors operating with HEU. This paper provides an update on the progress made since 2007 and describes current technical challenges that the program faces. (author)

  11. The effects of environmental regulation and technical progress on CO2 Kuznets curve: An evidence from China

    International Nuclear Information System (INIS)

    Based on environmental Kuznets curve theory, a panel data model which takes environmental regulation and technical progress as its moderating factors was developed to analyse the institutional and technical factors that affect the path of low-carbon economic development. The results indicated that there was a CO2 emission Kuznets curve seen in China. Environmental regulation had a significant moderating effect on the curve, and the inflection of CO2 emissions could come substantially earlier under stricter environmental regulation. Meanwhile, the impact of technical progress on the low-carbon economic development path had a longer hysteresis effect but restrained CO2 emission during its increasing stage and accelerated its downward trend during the decreasing stage which was conducive to emission reduction. Strict environmental regulation could force the high-carbon emitting industries to transfer from the eastern regions to the central or the western regions of China, which would make the CO2 Kuznets curve higher in its increasing stage and lower in its decreasing stage than that under looser regulation. Furthermore, energy efficiency, energy structure, and industrial structure exerted a significant direct impact on CO2 emissions; we should consider the above factors as essential in the quest for low-carbon economic development. - Highlights: • Estimate moderating effect of environmental regulation and technical progress on EKC. • There was a CO2 emission Kuznets curve in effect in China. • Environmental regulation presents significant moderating effect on EKC. • Technical progress moderates the relationship between income and CO2 emissions

  12. Biochemical removal of HAP precursors from coal. Quarterly technical progress report, 1996

    1996-12-31

    Shake flask tests were completed of microbial pyrite and HAP precursor removal from Rosebud subbituminous coal. Significant amounts of Ni, F, Mn, Cd, Co and Be were removed from this coal. Analyses in connection with leach column tests of Pittsburgh coal were completed and confirmed significant removal of Ni, F, Mn, Cd, Co and As from this coal. Although Hg was not removed from Pittsburgh coal by microbial attack, there was a correlation between HCl leaching of Hg from this coal and the extent of depyritization. Since HgS is soluble in HCl, the results suggest HgS is exposed by chemical and microbial dissolution of coal pyrite. Column tests with cleaned Indiana No. 5 coal are in progress and show significant early dissolution of Ni, Mn, Cd, Co and As. A final shake flask test with Kentucky No. 9 coal was begun. Pittsburgh coal with a low content of fines was shipped to the Idaho National Engineering Laboratory (INEL) in preparation for slurry column tests of HAP precursor removal. Project results were presented at the PETC contractor`s conference held in Pittsburgh. A project progress review meeting was also held with the PETC technical project monitor.

  14. Colorado School of Mines Low Energy Nuclear Physics Project technical progress report

    International Nuclear Information System (INIS)

    This report summarizes the activity and accomplishments of the Colorado School of Mines Low Energy Nuclear Physics project during the calendar year 1989. Many of the projects which were anticipated in the original grant proposal have been completed. Among these completed projects we include of study of the radiative capture of low energy protons on 6Li, 7Li, 9Be, and 11B. Preliminary measurements of the branching ratios and yields of these reactions were reported in last year's Technical Progress Report. These measurements are now complete and have been used to extract the respective astrophysical S-factors and the corresponding thermonuclear reactivities. While not complete, progress has been made in some of the other originally proposed studies. Among these include a fairly extensive study of the interaction of low energy deuterons with 6Li and 7Li. In the course of this study we have made a solid observation of the Oppenheimer-Phillips effect in the D-6Li system. Progress has been made in our study of the radiative capture of alpha particles by deuterons, 6Li, and 7Li but considerable work remains in these studies. In our earlier reports we noted the observation of d-d reactions during the bombardment of deuterated targets with energetic beams of protons, alpha particles, and other light-to-medium ions. We believe we now understand this phenomenon and feel it has some fairly significant consequences both for our studies and for those of other researchers. Our susceptibility to mob hysteria led us to invest a significant effort in cold nuclear fusion, both employing a fairly unique accelerator based approach at CSM and as one of the gamma ray diagnosticians on the Princeton Plasma Physics Laboratory's Cold Fusion Task Force

    Background Endovascular therapy plays an important role in the treatment of brain arteriovenous malformations (BAVMs).Ethylene vinyl alcohol copolymer (Onyx) is a novel liquid embolic material.This study aimed to summarize our experience of using Onyx for embolization of BAVMs with the focus on embolization technique.Methods From September 2003 to November 2007,115 patients (43 women and 72 men,with a mean age of 29 years)with BAVMs were endovascularly treated with Onyx in our department.The following features of all AVMs were evaluated prior to treatment:type of nidus and shunt,draining veins,and feeding arteries.A total of 196 endovascular procedures were performed.Results The course of endovascular treatment was completed in 88 patients.Additional sessions were planned in 27 patients.Of the 88 patients,total occlusion was obtained in 23 patients (26.1%),near-total (>80% of the original volume) occlusion was obtained in 35 patients (39.8%) and partial occlusion (<80% of the original volume) was obtained in 30 patients (34.1%) using embolization as the sole therapeutic technique.Mean volume reduction was 72% (range 30%-100%) in 115 patients.Thirty four patients (38.6%,34/88) underwent radiosurgical treatment.Additional embolization sessions were planned in 27 patients.Complications occurred in 19 patients (16.5%,19/115),leading to death in one patient (mortality 0.9%) and permanent disabling in 3 patients (morbidity 2.6%).Conclusions Onyx was shown to be feasible and safe for embolization of BAVMs.Proper use of the Onyx injection technique largely improved the endovascular treatment of BAVMs.Large AVMs can be adequately reduced in size through the use of additional treatment.

  18. [Chemical risk in operating rooms and technical progress: the obligations and responsibilities of law].

    2013-01-01

    We are going to consider the specific applications of the new legal system and of the most recent body of laws to those work environments of particular risk, such as healthcare facilities and in particular operating rooms. In such environments, volatile chemicals classified as "dangerous" are used with consequent exposure to "chemical risk", both of those persons professionally involved, depending on the type of activity, and of the patients to whom such activities are addressed in the same environment. Once the chemical risk is framed in the existing regulatory system, it must be specifically evaluated the application of the same principle to the particular chemical risk arising from the use of anesthetic agents in the operating room, for example sevoflurane and desflurane, being careful to test wether and how much this risk can be eliminated or reduced to minimum in relation to the new achievements of the technical progress. So, as soon as the quality of "dangerous chemical agent" of the "volatile chemicals" and of the "volatile liquid anesthetic" (sevoflurane and desflurane) as well--which are characterized by a lower degree of toxicity and for this reason are mostly used in current chemical practice, preferable to some anesthetic gases such as nitrous oxide--is legally verified, it is necessary to relate the scientific and technical data which result from the current "state of art" also to the other binding regulations that are imposed for the "prevention and protection from chemical agents", according to the relative Title IX of the TUSL (Unique text for Safety and Health at Work).

    Alcohol is the most frequently consumed toxic substance in the world. Low to moderate daily intake of alcohol has been shown to have beneficial effects on the cardiovascular system. In contrast, exposure to high levels of alcohol for a long period could lead to progressive cardiac dysfunction and heart failure. Cardiac dysfunction associated with chronic and excessive alcohol intake is a specific cardiac disease known as alcoholic cardiomyopathy(ACM). In spite of its clinical importance, data on ACM and how alcohol damages the heart are limited. In this review, we evaluate available evidence linking excessive alcohol consumption with heart failure and dilated cardiomyopathy. Additionally, we discuss the clinical presentation, prognosis and treatment of ACM.

  20. Monitoring the progress of build-up formation in fatty alcohol plant pipelines using gamma-ray scanning techniques

    International Nuclear Information System (INIS)

    A study was conducted to monitor the progress of material build-up formation in fatty acid alcohol pipelines using gamma ray absorption techniques. The investigation was periodically performed at few selected location which has been defined as critical area. Before performing a scan, the intensity of the gamma ray as a reference at the clean pipe should be determined. From the gamma ray absorption principle, the intensity of the radiation initial and the radiation after it pass through a material should be different, so the thickness of the build-up in the pipeline can be determined. As a result, base on this early information of the actual condition of the build-up formation, the more effective maintenance schedule can be planned. From that, the maintenance cost which is due to the build-up formation could be minimise as low as possible. (Author)

    1989-12-31

    The purpose of this project is to elucidate the way in which the fermentative synthesis of ethanol is regulated in the facultative anaerobe Escherichia coli. We are also investigating the control of other genes required for fermentation and anaerobic growth. We have isolated both structural and regulatory mutations affecting the expression of alcohol dehydrogenase, the enzyme responsible for the final step in alcohol synthesis. Some of these regulatory mutations also affect other anaerobically induced genes. The adh gene has been cloned and sequenced. The ADH protein is one of the largest highly expressed proteins in E. coli and requires approximately 2700bp of DNA for its cloning sequence. We have also isolated mutations affecting the fermentative lactate dehydrogenase. In consequence it is now possible to construct E. coli strains defective in the production of any one or more of their normal fermentation products (i.e. formate, acetate, lactate, ethanol and succinate). The factors affecting the ratio of fermentation products are being investigated by in vivo NMR spectroscopy.

    The Magnetohydrodynamics (MHD) Integrated Topping Cycle (ITC) Project represents the culmination of the proof-of-concept (POC) development stage in the US Department of Energy (DOE) program to advance MHD technology to early commercial development stage utility power applications. The project is a joint effort, combining the skills of three topping cycle component developers: TRW, Avco/TDS, and Westinghouse. TRW, the prime contractor and system integrator, is responsible for the 50 thermal megawatt (50 MW{sub t}) slagging coal combustion subsystem. Avco/TDS is responsible for the MHD channel subsystem (nozzle, channel, diffuser, and power conditioning circuits), and Westinghouse is responsible for the current consolidation subsystem. The ITC Project will advance the state-of-the-art in MHD power systems with the design, construction, and integrated testing of 50 MW{sub t} power train components which are prototypical of the equipment that will be used in an early commercial scale MHD utility retrofit. Long duration testing of the integrated power train at the Component Development and Integration Facility (CDIF) in Butte, Montana will be performed, so that by the early 1990`s, an engineering data base on the reliability, availability, maintainability and performance of the system will be available to allow scaleup of the prototypical designs to the next development level. This Sixteenth Quarterly Technical Progress Report covers the period May 1, 1991 to July 31, 1991.

    Pacific Northwest National Laboratory has been conducting research to investigate the feasibility of producing mixed alcohols from biomass-derived synthesis gas (syngas). In recent years, this research has primarily involved the further development of catalysts containing rhodium and manganese based on the results of earlier catalyst screening tests. Testing continued in FY 2012 to further improve the Ir-promoted RhMn catalysts on both silica and carbon supports for producing mixed oxygenates from synthesis gas. This testing re-examined selected alternative silica and carbon supports to follow up on some uncertainties in the results with previous test results. Additional tests were conducted to further optimize the total and relative concentrations of Rh, Mn, and Ir, and to examine selected promoters and promoter combinations based on earlier results. To establish optimum operating conditions, the effects of the process pressure and the feed gas composition also were evaluated.

    Full Text Available Alcoholic hallucinosis is a rare complication of chronic alcohol abuse characterized by predominantly auditory hallucinations that occur either during or after a period of heavy alcohol consumption. Bleuler (1916 termed the condition as alcohol hallucinosis and differentiated it from Delirium Tremens. Usually it presents with acoustic verbal hallucinations, delusions and mood disturbances arising in clear consciousness and sometimes may progress to a chronic form mimicking schizophrenia. One such case with multimodal hallucinations in a Defence Service Corps soldier is presented here.

The major particulate control device issues to be addressed include the integration of the particulate control devices into coal utilization systems, on-line cleaning techniques, chemical and thermal degradation of components, fatigue or structural failures, blinding, collection efficiency as a function of particle size, and scaleup of particulate control systems to commercial size. The conceptual design of the facility was extended to include a within scope, phased expansion of the existing Hot Gas Cleanup Test Facility Cooperative Agreement to also address systems integration issues of hot particulate removal in advanced coal-based power generation systems. This expansion included the consideration of the following modules at the test facility in addition to the existing Transport Reactor gas source and Hot Gas Cleanup Units: Carbonizer/Pressurized Circulating Fluidized Bed Gas Source. Hot Gas Cleanup Units to mate to all gas streams; Combustion Gas Turbine; and Fuel Cell and associated gas treatment. This expansion to the Hot Gas Cleanup Test Facility is herein referred to as the Power Systems Development Facility (PSDF). The major emphasis during this reporting period was continuing the detailed design of the facility.

    This report describes the technical progress made on the Advanced Coal Conversion Process (ACCP) Demonstration Project from January 1, 1995 through December 31, 1995. This project demonstrates an advanced, thermal, coal upgrading process, coupled with physical cleaning techniques, that is designed to upgrade high-moisture, low-rank coals to a high-quality, low-sulfur fuel, registered as the SynCoal Process. The coal is processed through three stages (two heating stages followed by an inert cooling stage) of vibrating fluidized bed reactors that remove chemically bound water, carboxyl groups, and volatile sulfur compounds. After thermal upgrading, the coal is put through a deep-bed stratifier cleaning process to separate the pyrite-rich ash from the coal. The SynCoal Process enhances low-rank, western coals, usually with a moisture content of 25 to 55 percent, sulfur content of 0.5 to 1.5 percent, and heating value of 5,5000 to 9,000 British thermal units per pound (Btu/lb), by producing a stable, upgraded, coal product with a moisture content as low as 1 percent, sulfur content as low as 0.3 percent, and heating value up to 12,000 Btu/lb. During this reporting period, the primary focus for the ACCP Demonstration Project team was to expand SynCoal market awareness and acceptability for both the products and the technology. The ACCP Project team continued to focus on improving the operation, developing commercial markets, and improving the SynCoal products as well as the product`s acceptance.

    This is the eighteenth Technical Progress Report submitted in connection with the cooperative agreement between the DOE and Ohio Power Company for the Tidd PFBC Hot Gas Clean Up Test Facility. During this quarter, the Tidd Hot Gas Clean Up System operated for 835 hours during six separate test runs. The system was starting into a seventh run at the end of the quarter. Highlights of this period are summarized below: the longest run during the quarter was approximately 333 hours; filter pressure drop was stable during all test runs this quarter using spoiling air to the primary cyclone upstream of the Advanced Particle Filter (APF); the tempering air system was commissioned this quarter which enabled the unit to operate at full load conditions while limiting the gas temperature in the APF to 1,400 F; during a portion of the one run, the tempering air was removed and the filter operated without problems up to 1,450 F; ash sampling was performed by Battelle personnel upstream and downstream of the APF and ash loading and particle size distribution data were obtained, a summary report is included; a hot area on the APF head was successfully repaired in service; a hot spot on the top of an expansion joint was successfully repaired by drilling holes from the inside of the pipe and pumping in refractory insulation; a corrosion inspection program for the HGCU system was issued giving recommendations for points to inspect; filter internal inspections following test runs 13 and 17 revealed a light coating (up to 1/4 inch thick) of residual ash on the candles and some ash bridging between the dust sheds and inner rows of candles. Data from these inspections are included with this report.

  13. Korean red ginseng extract suppresses the progression of alcoholic fatty liver in a rat model

    International Nuclear Information System (INIS)

    Alcoholic fatty liver (AFL) is the most common liver disease among Korean men, and Korean red ginseng has been used as a folk medicine to diverse diseases in Korea. Therefore, we examined if Korean red ginseng extract (KRG) could be a suppressive agent on AFL in a rat model or not. Experimental rats were fed the Lieber DeCarli diet with 36% of energy intake from ethanol, and divided into three groups which daily co-administered KRG 0, 700 and 1400 mg/kg for six weeks, respectively. Naive rats were fed iso-caloric control diet without ethanol and KRG. We investigated histopathological hepatic characteristics, hepatic and plasma lipid concentrations, hepatic hydroxyproline contents, heart/liver radioactivity ratio of 201Thallium and liver/body weight of the rats at the end point. Ethanol intake brought about steatotic, inflammatory, necrotic and fibrotic changes of livers significantly, and it also lead the rats to increase hepatic triglyceride and hydroxyproline contents, plasma total cholesterol and low density lipoprotein cholesterol levels, and liver/body weight. However, co-administration of KRG 1400 mg/kg suppressed fat accumulation and fibrotic initiation in AFL rat model significantly. It was also inclined to attenuate inflammatory cell infiltration, hydroxyproline accumulation, and increasing liver/body weight, even though plasma lipid levels and heart/liver ratios were not successfully improved by six-week-long intakes of KRG. In conclusions, co-administration of KRG 1400 mg/kg could significantly suppress steatosis in AFL rat model, and it might need longer ingestion of KRG than six weeks to improve plasma lipid imbalance.

    ALCOHOL ABUSE AND alcoholism result from the complex interplay of genetic and environmental factors. Stress is a factor that is widely thought to contribute to excessive drinking and alcoholism. One consequence of stressful experiences is anxiety, and there is a rich literature on the interactions between alcohol and anxiety. Less is known about brain mechanisms at the molecular, cellular, and system levels that mediate stress effects that contribute to excessive drinking and alcoholism. In addition, it is not clear whether and/or how genetic factors that contribute to excessive drinking interact with neural stress mechanisms.

  18. Coal to SNG: Technical progress, modeling and system optimization through exergy analysis

    International Nuclear Information System (INIS)

    Highlights: • Technical progresses of coal to SNG technologies are reported. • The entire coal to SNG system is modeled. • Coupling between SNG production and power generation is investigated. • Breakthrough points for further energy saving are determined. • System performance is optimized based on the first and second laws of thermodynamics. - Abstract: For both energy security and CO2 emission reduction, synthetic natural gas (SNG) production from coal is an important path to implement clean coal technologies in China. In this paper, an overview of the progress of coal to SNG technologies, including the development of catalysts, reactor designs, synthesis processes, and systems integration, is provided. The coal to SNG system is modeled, the coupling between SNG production and power generation is investigated, the breakthrough points for further energy savings are determined, and the system performance is optimized based on the first and the second laws of thermodynamics. From the viewpoint of the first law of thermodynamics, the energy conversion efficiency of coal to SNG system can reach 59.8%. To reduce the plant auxiliary power, the breakthrough points are the development of low-energy-consumption oxygen production technology and gas purification technology or seeking new oxidants for coal gasification instead of oxygen. From the viewpoint of the second law of thermodynamics, the major exergy destruction in a coal to SNG system occurs in the coal gasification unit, SNG synthesis unit and the raw syngas cooling process. How to reduce the exergy destruction in these units is the key to energy savings and system performance enhancement. The conversion ratio of the first SNG synthesis reactor and the split ratio of the recycle gas are key factors that determine the performance of both the SNG synthesis process and the whole plant. A “turning point” phenomenon is observed: when the split ratio is higher than 0.90, the exergy destruction of the SNG

    1997-12-01

    The nine-month Phase 1 feasibility study was directed toward the application of supercritical water gasification (SCWG) for the economical production and end use of hydrogen from renewable energy sources such as sewage sludge, pulp waste, agricultural wastes, and ultimately the combustible portion of municipal solid waste. Unique in comparison to other gasifier systems, the properties of supercritical water (SCW) are ideal for processing biowastes with high moisture content or contain toxic or hazardous contaminants. During Phase I, an end-to-end SCWG system was evaluated. A range of process options was initially considered for each of the key subsystems. This was followed by tests of sewage sludge feed preparation, pumping and gasification in the SCW pilot plant facility. Based on the initial process review and successful pilot-scale testing, engineering evaluations were performed that defined a baseline system for the production, storage and end use of hydrogen. The results compare favorably with alternative biomass gasifiers currently being developed. The results were then discussed with regional wastewater treatment facility operators to gain their perspective on the proposed commercial SCWG systems and to help define the potential market. Finally, the technical and business plans were developed based on perceived market needs and the projected capital and operating costs of SCWG units. The result is a three-year plan for further development, culminating in a follow-on demonstration test of a 5 MT/day system at a local wastewater treatment plant.

    International Nuclear Information System (INIS)

    The Savannah River Ecology Laboratory (SREL) is a research unit of The University of Georgia (UGA) and has been conducting ecological research on the Savannah River Site (SRS) near Aiken, South Carolina for 50 years. The overall mission of the Laboratory is to acquire and communicate knowledge of ecological processes and principles. SREL conducts fundamental and applied ecological research, as well as education and outreach programs, under a Cooperative Agreement with the U.S. Department of Energy (DOE). The Laboratory's research mission during the 2002 fiscal year was fulfilled with the publication of 76 journal articles and book chapters by faculty, technical staff, students, and visiting scientists. An additional 50 journal articles have been submitted or are in press. Other noteworthy events took place as faculty members, staff, and graduate students received awards. These are described in the section titled Special Accomplishments of Faculty, Staff, Students, and Administration on page 51. Notable scientific accomplishments include work conducted on contaminant transport, stable isotopes, sandhills ecology, and phytoremediation: (1) A collaborative study between Dr. Tom Hinton at SREL and scientists at SRTC demonstrated the feasibility of using illite clay to sequester 137Cs in sediments along the P and R reactor cooling canal system, where approximately 3, 000 acres of land are contaminated. Overall, the study showed significant decreases in cesium concentrations and bioavailability following the addition of illite with no sign of harm to the ecosystem. While the cesium remains sequestered from the biosphere, its radioactivity decays and the process progresses from contaminant immobilization to remediation. (2) SREL's stable isotope laboratory is now fully functional. Stable isotope distributions in nature can provide important insights into many historical and current environmental processes. Dr. Christopher Romanek is leading SREL's research in this area

  4. High-Efficiency Nitride-Based Solid-State Lighting. Final Technical Progress Report

    International Nuclear Information System (INIS)

    In this final technical progress report we summarize research accomplished during Department of Energy contract DE-FC26-01NT41203, entitled ''High-Efficiency Nitride-Based Solid-State Lighting''. Two teams, from the University of California at Santa Barbara (Principle Investigator: Dr. Shuji Nakamura) and the Lighting Research Center at Rensselaer Polytechnic Institute (led by Dr. N. Narendran), pursued the goals of this contract from thin film growth, characterization, and packaging/luminaire design standpoints. The UCSB team initially pursued the development of blue gallium nitride (GaN)-based vertical-cavity surface-emitting lasers, as well as ultraviolet GaN-based light emitting diodes (LEDs). In Year 2, the emphasis shifted to resonant-cavity light emitting diodes, also known as micro-cavity LEDs when extremely thin device cavities are fabricated. These devices have very directional emission and higher light extraction efficiency than conventional LEDs. Via the optimization of thin-film growth and refinement of device processing, we decreased the total cavity thickness to less than 1 (micro)m, such that micro-cavity effects were clearly observed and a light extraction efficiency of over 10% was reached. We also began the development of photonic crystals for increased light extraction, in particular for so-called ''guided modes'' which would otherwise propagate laterally in the device and be re-absorbed. Finally, we pursued the growth of smooth, high-quality nonpolar a-plane and m-plane GaN films, as well as blue light emitting diodes on these novel films. Initial nonpolar LEDs showed the expected behavior of negligible peak wavelength shift with increasing drive current. M-plane LEDs in particular show promise, as unpackaged devices had unsaturated optical output power of ∼ 3 mW at 200 mA drive current. The LRC's tasks were aimed at developing the subcomponents necessary for packaging UCSB's light emitting diodes, and packaging them to produce a white light

    A271 GT-MHR COMMERCIALZATION STUDY TECHNICAL PROGRESS AND COST MANAGEMENT REPORT FOR THE PERIOD MAY 1 THROUGH MAY 31, 2003. Petten advised GA the start of the HFR-EU2 irradiation is being delayed until late July 2004. HFR-EU1 (pebble fuel) is also delayed until February/March 2004. The reason for the delays was implementation of new financial regulations at Petten that delayed the contracts for capsule fabrication. Review of the MHR-2 Fuel Product Specification was completed. Revision of the specification to incorporate the review results is in progress. Detailed test matrices have been drafted for capsule irradiation tests and for post-irradiation heating tests proposed for development and qualification of advanced coated-particle fuels capable of meeting anticipated VHTR fuel performance requirements

Various organic ethers, hydroxy ethers, ether ketones, acids, amides, and diketones were studied for their ability to extract uranyl nitrate from aqueous solutions. Although many of these solvents were obtained commercially, others had to be synthesized in-house. The authors found a large range of extraction coefficients for these solvents. Because of steric hindrance or some other factor, certain ethers performed poorly. On the other hand, various mono- and diethers of tetrahydrofurfuryl alcohol exhibited excellent extraction and stripping coefficients for uranyl nitrate, justifying purchase of a pilot plant batch of one of this family of solvents. Likewise, the authors determined the extraction coefficient for one of the two amides synthesized in-house to be quite high

    1992-04-01

    This Technical Progress Report describes the progress made on the research objectives during the past twelve months. This research project is designed to provide measurements of various scattering processes which occur in H{sup {minus}} collisions with atomic (specifically, noble gas and atomic hydrogen) targets at intermediate energies. These processes include: elastic scattering,single- and double-electron detachment, and target excitation/ionization. For the elastic and target inelastic processes where H{sup {minus}} is scattered intact, the experimental technique of Ion Energy-Loss Spectroscopy (IELS) will be employed to identify the final target state(s). In most of the above processes, cross sections are unknown both experimentally and theoretically. The measurements in progress will provide either experimentally-determined cross sections or set upper limits to those cross sections. In either case, these measurements will be stringent tests of our understanding in energetic negative ion-atom collisions. This series of experiments required the construction of a new facility and the initial ion beam was accelerated through the apparatus in April 1991.

    Dispersed solar thermal power systems applied to farm irrigation energy needs are analyzed. The 17 western states, containing 84% of nationwide irrigated croplands and consuming 93% of nationwide irrigation energy, have been selected to determine were solar irrigation systems can compete most favorably with conventional energy sources. Financial analysis of farms, according to size and ownership, was accomplished to permit realistic comparative analyses of system lifetime costs. Market potential of optimized systems has been estimated for the 17-state region for near-term (1985) and intermediate-term (2000) applications. Technical, economic, and institutional factors bearing on penetration and capture of this market are being identified.

    Smit, F.J.; Hogsett, R.F.; Jha, M.C.

    1993-11-04

    This project is a major step in the Department of Energy`s program to show that ultra-clean coal-water slurry fuel (CWF) can be produced from selected coals and that this premium fuel will be a cost-effective replacement for oil and natural gas now fueling some of the industrial and utility boilers in the United States. The replacement of oil and gas with CWF can only be realized if retrofit costs are kept to a minimum and retrofit boiler emissions meet national goals for clean air. These concerns establish the specifications for maximum ash and sulfur levels and combustion properties of the CWF. This cost-share contract is a 48-month program which started on September 30, 1992. This report discusses the technical progress made during the 4th quarter of the project from July 1 to September 30, 1993.

The ACCP Demonstration Project is a US Department of Energy (DOE) Clean Coal Technology Project. This project demonstrates an advanced, thermal, coal upgrading process, coupled with physical cleaning techniques, that is designed to upgrade high-moisture, low-rank coals to a high-quality, low-sulfur fuel, registered as the SynCoal process. The coal is processed through three stages (two heating stages followed by an inert cooling stage) of vibrating fluidized bed reactors that remove chemically bound water, carboxyl groups, and volatile sulfur compounds. After thermal upgrading, the cola is put through a deep-bed stratifier cleaning process to separate the pyrite-rich ash from the coal.

    1995-07-01

    On September 30, 1993, the U.S. Department of Energy-Morgantown Energy Technology Center and Southern Illinois University at Carbondale (SIUC) entered into a cooperative research agreement entitled {open_quotes}Management of Dry Flue Gas Desulfurization By-Products in Underground Mines{close_quotes} (DE-FC21-93MC30252). Under the agreement Southern Illinois University at Carbondale will develop and demonstrate several technologies for the placement of coal combustion residues in abandoned coal mines, and will assess the environmental impact of such underground residues placement. Previous quarterly Technical Progress Reports have set forth the specific objectives of the program, and a discussion of these is not repeated here. Rather, this report discusses the technical progress made during the period April 1 - June 30, 1995. A final topical report on the SEEC, Inc. demonstration of its technology for the transporting of coal combustion residues was completed during the quarter, although final printing of the report was accomplished early in July, 1995. The SEEC technology involves the use of Collapsible Intermodal Containers (CIC`s) developed by SEEC, and the transportation of such containers - filled with fly ash or other coal combustion residues - on rail coal cars or other transportation means. Copies of the final topical report, entitled {open_quotes}The Development and Testing of Collapsible Intermodal Containers for the Handling and Transport of Coal Combustion Residues{close_quotes} were furnished to the Morgantown Energy Technology Center. The Rapid Aging Test colums were placed in operation during the quarter. This test is to determine the long-term reaction of both the pneumatic and hydraulic mixtures to brine as a leaching material, and simulates the conditions that will be encountered in the actual underground placement of the coal combustion residues mixtures. The tests will continue for about one year.

  17. The influence of alkyl polyglucosides (and highly ethoxylated alcohol boosters on the phase behavior of a water/toluene/technical alkyl polyethoxylate microemulsion system

    Full Text Available The influence of additives (alkyl polyglucoside, Glucopon 600 CS UP and alcohol ethoxylate C18E100 on the behavior of the water/toluene/Lutensol ON 50 (technical oxoalcohol, i-C10E5 microemulsion system as a function of temperature and composition has been investigated. The phase behavior of the microemulsions was determined by vertical sections through the Gibbs phase prism (fish-like phase diagrams. Alkyl polyglucoside shifts the one phase region to lower temperatures compared with water/toluene/Lutensol ON 50 mixtures. This is contrary to the expectation, considering the extreme hydrophilic nature of the sugar headgroup. The addition of hydrophilic alcohol ethoxylate (C18E100 to the water/toluene/Lutensol ON 50 system increases the solubilization capacity of the surfactant, even if the co-surfactant is used in small quantities, and shifts the one-phase region to higher temperature by a few degrees Celsius.

    1980-01-01

    Progress in research to evaluate the impact of utilization of fossil fuels on surface water is reported. Analyses of regulatory mechanisms of growth and rates of carbon cycling center on evaluation of quantitative control interactions among the microflora of the pelagial zones of several lakes of progressively greater eutrophy, littoral photosynthetic producer-decomposer complex, and allochthonous inorganic-organic influxes and their biotic processing. The underlying thesis is that quantification of the dynamic carbon fluxes among these components and their rate control mechanisms by physical and chemical factors are fundamental to elucidation of the rate functions of lake eutrophication. A major portion of the research has been directed towards the fate and nutrient mechanisms regulating qualitative and quantitative utilization and losses of organic carbon synthesized within lakes and their drainage basins. It has become increasingly apparent that the wetland and littoral flora, and attendant epiphytic and benthic microflora, have major regulatory controls on biogeochemical cycling of whole lake systems. A major effort on factors regulating the metabolism of littoral macrophytes and attached algae has been coupled to integrated studies on their decomposition and the fate of detrital dissolved and particulate organic matter. These organic products are being coupled to influences on enzymatic activity and inorganic nutrient cycling.

    This Progress Report summarizes work carried out at the Nuclear Physics Laboratory of the University of Colorado from November 1, 1980 through July 31, 1981, under contracts between the University of Colorado and the United States Department of Energy. The shorter report period of nine months is due to a change to an earlier submission date this year for our proposal for support to begin February 1, 1982. Cyclotron operation, research, and development have been supported under contract DE-AC02-81ER40014. The AVF cyclotron has continued to provide reliable and versatile beams of protons, deuterons, 3He and 4He. A wide variety of research results in direct reactions, nuclear structure, and compound reaction mechanisms can be noted in this Progress Report, correlated in many cases to current problems in intermediate energy physics. Theoretical work on nuclear reactions, carried out under contract DE-AC02-81ER40015, has been well matched to our experimental programs in low and intermediate energy physics. One important result has been the recasting of the DWBA in an eikonal expansion suited to high energy reactions. Our efforts in intermediate energy physics, under contract DE-AC02-81ER40016, have emphasized pion scattering studies at LAMPF and TRIUMF and proton induced charge exchange reactions at IUCF. Data for an important test of hadronic charge symmetry have been completed at two energies, using elastic pion-deuteron scattering

    The Penn State program in advanced thermally stable coal-based jet fuels has five borad objectives: (1) development of mechanisms of degradation and solids formation; (2) quantitative measurement of growth of sub-micrometer and miocrometer-sized particles suspended in fuels during thermal stressing; (3) characterization of carbonaceous deposits by various instrumental and microscopic methods; (4) elucidation of the role of additives in retarding the formation of carbonaceous solids; and (5) assessment of the potential of production of high yields of cycloalkanes by direct liquefaction of coal. Pyrolysis of four isomers of butylbenzene was investigated in static microautoclave reactors at 450{degrees}C under 0.69 MPa of UHP N{sub 2}. Thee rates of disappearance of substrates were found to depend upon the bonding energy of C{alpha}-C{beta} bond in the side chain in the initial period of pyrolysis reactions. Possible catalytic effects of metal surfaces on thermal degradation and deposit formation at temperatures >400{degrees}C have been studied. Carbon deposition depends on the composition of the metal surfaces, and also depends on the chemical compositions of the reactants. Thermal stressing of JP-8 was conducted in the presence of alumina, carbonaceous deposits recovered from earlier stressing experiments, activated carbon, carbon black, and graphite. The addition of different solid carbons during thermal stressing leads to different reaction mechanisms. {sup 13}C NMR spectroscopy, along with {sup 13}C-labeling techniques, have been used to examine the thermal stability of a jet fuel sample mixed with 5% benzyl alcohol. Several heterometallic complexes consisting of two transition metals and sulfur in a single molecule were synthesized and tested as precursors of bimetallic dispersed catalysts for liquefaction of a Montana subbituminous and Pittsburgh No. 8 bituminous coals.

    1992-03-03

    Following a long period of theoretical interest, but only limited measurements, there has recently been an increased number of attempts to expand the relative paucity of experimental information on the structure of liquid surfaces using techniques as diverse as ellipsometry, micro-force balances, non-linear optics, Auger and photoelectron spectroscopy, and x-ray scattering. Our group has played a leading role in the currently expanding application of scattering techniques to the general problem of characterizing the microscopic structure of liquid surfaces and we propose here that this work be extended specifically to liquid metals. In the following sections we will briefly describe the salient features of x-ray scattering that are relevant to the current project, the progress that we have made in the current grant period and the work that we propose to carry out in the forthcoming grant period.

  14. Scientific and technical progress in high-energy astrophysics at INPE

    International Nuclear Information System (INIS)

    The recent advances in high-energy Astrophysics pertains to the study of compact objects in galactic nuclei, binary systems and pulsars. These aspects are best understood by the study of the emissions in X- and gamma rays of these objects through the temporal variation in flux and spectrum. The Southern Hemisphere offers some of the unique objects for investigations such as galactic center, the Vela pulsar etc. For high temporal and spectra resolution studies two telescopes 'GeLi' and 'Pulsar' were designed and constructed. To support these scientific activities, a program in balloon launching and data acquisition facilities has been developed since 1971. The 'Balloon Launching Center' of INPE has capacity to launch balloons of -850,000 m3 with payloads weighting about 1,000 Kg. Taking advantage of these facilities, project 'Bantar', with the goal to measure the atmospheric gamma-ray radiation in the Antartic Region, is under progress. (Author)

    1993-10-25

    The overall objective of the project is to develop an integrated two stage fermentation process for conversion of coal-derived synthesis gas to a mixture of alcohols. This is achieved in two steps. In the first step, Butyribacterium methylotrophicum converts carbon monoxide (CO) to butyric and acetic acids. Subsequent fermentation of the acids by Clostridium acetobutylicum leads to the production of butanol and ethanol. The tasks for this quarter were: (1) development/isolation of superior strains for fermentation of syngas, (2) optimization of process conditions for fermentation of syngas, (3) evaluation of bioreactor configuration for improved mass transfer of syngas, (4) development of a membrane-based pervaporation system, (5) optimization of process conditions for reducing carbon and electron loss by H{sub 2}-CO{sub 2} fermentation, and (6) synthesis gas fermentation in single-stage by co-culture.

    The primary objective of the HCCP is to demonstrate a new power plant design integrating an advanced combustor and heat recovery system coupled with both high and low temperature emission control processes. Alaskan bituminous and subbituminous coals will be the fuels. Emissions of SO{sub 2} and NO{sub x} from the plant will be controlled using a slagging coal combustor with limestone injection, in conjunction with a boiler. Further SO{sub 2} and particulate removal will be accomplished using an Activated Recycle Spray Absorber System. Environmental efforts during this quarter concentrated on supporting the Alaska Department of Environmental Conservation`s (ADEC) insurance of the Final Prevention of Significant Deterioration (PSD)/Permit to Operate, preparation of post-construction Air Quality Monitoring and Visibility Monitoring Plans, preparation of a General Wastewater Discharge Permit Application for disposal of wastewater from on-site excavations, review of a PreDraft National Pollutant Discharge Elimination System (NPDES) Permit and Fact Sheet and discussions with the Environmental Protection Agency (EPA) and ADEC on NPDES Permit limitations, and preparation of a draft Storm Water Pollution Prevention Plan for HCCP construction. The final PSD/Permit to Operate No. 9431-AA001 and Technical Analysis Report (TAR) was issued on May 12, 1994. Finalization of engineering and design continued on the boiler, combustors, flue gas desulfurization (FGD), and turbine/generator systems and balance of plant.

    From 2009 inclusive, NINA has received economic support for research on power lines and wildlife from the Norwegian Research Council (NFR) through the RENERGI Programme. The project is named 'Optimal design and routing of power lines; ecological, technical and economic perspectives' (OPTIPOL). It is scheduled for 5 years (2009-1013) and is part of the activities within CEDREN, i.e. the Centre for environmental design of renewable energy (cf. http://www.cedren.no). With a grid close to 200 000 km overhead power-lines, the associated rights-of-way (ROW) affect huge land areas in Norway. The overall goal is to develop predict-ing tools for optimal routing of power lines from an environmental perspective and assess technical and economic solutions to minimize conflicts with wildlife and habitat conservation. Thus, the OPTIPOL rationale is based on the belief that the negative effects of electricity transmission and distribution can be reduced with respect to birds and mammals. OPTIPOL has several ambitious objectives, and is divided into sub-projects and specific tasks. From the first of November a PhD-student became part of the project, a position that will be held for 4 years. The main objective of the PhD-activities will be to assess how and why different wildlife species use deforested areas below power lines, evaluate possible positive and negative effects of power-line ROWs, and assess the possibilities for quality improvement. Another part of the project is dedicated the effects of linear structures on movement patterns and distribution in the landscape in native deer species. Here we will examine how different spatial scales influence the processes that guide movement patterns, and responses to linear structures. Another focus will be small game species, with mountain hare, capercaillie, black grouse and hazel grouse as model species. The main objective will be to assess the impact of transforming ROW habitats into attractive small-game foraging

    Interactions of dissolved organic matter with inorganic nutrient cycling and regulation of the photosynthetic and decompositional metabolism of micro- and macroflora remains the focal point of these studies. Major efforts are directed towards the sources, fates, pathways, and interactions of dissolved organic matter in inorganic chemical cycling; allochthonous sources, metabolism en route, and inputs to the lake systems of increasing stages of eutrophication; and the relationships of these compounds to the nutrient physiology and metabolism of phytoplankton, sessile algae, macrophytes, and bacterial populations of the littoral zones and wetlands of the drainage basin. Analyses of regulatory mechanisms of growth and rates of carbon cycling center on evaluation of quantitative control interactions among the microflora of the pelagial zones of seversal lakes of progressively greater eutrophy, littoral photosynthetic producer-decomposer complex, and allochthonous inorganic--organic influxes and their biotic processing. The underlying thesis is that quantification of the dynamic carbon fluxes among these components and their rate control mechanisms by physical and chemical factors are fundamental to elucidation of the rate functions of lake eutrophication.

    Progress is reported in continuing investigations focused on integrated studies of the qualitative and quantitative cycling and metabolism of particulate and dissolved organic carbon in lakes and their inflow sources (surface and subsurface). Emphasis is placed on the sources, fates, and interactions of dissolved and particulate organic matter in relation to: (a) inorganic chemical cycling, (b) allochthonous loading to the lake system, and (c) the coupled nutrient physiology and metabolism of phytoplankton, bacterial populations, macrophytes, and attendant sessile algal-bacterial communities. Regulatory mechanisms of growth and rates of carbon and nutrient cycling are being evaluated among the (a) inorganic-organic influxes of allochthonous sources as they are controlled by wetland-littoral communities, (b) the littoral photosynthetic producer-decomposer complex, and (c) the microflora of the pelagial zone. Quantification of carbon fluxes among these components and control mechanisms is fundamental to elucidation of the rate functions of lake eutrophication. The integrated studies addressing these multifacted objectives are summarized in three summary diagrams.

    This report summarizes the progress of the Exploratory Research on Solvent Refined Coal Liquefaction project by The Pittsburgh and Midway Coal Mining Company's Merriam Laboratory for the period April 1, 1979 through June 30, 1979. Experimental work included a number of short residence time runs, but discussion of that work has been delayed until a later report. Experimental work reported focuses on an investigation of the decline in solvent quality experienced by the Wilsonville Pilot Plant during runs in support of the SRC I Demonstration Plant. A four run series was initiated with Wilsonville solvent; both the coal used at Wilsonville (Kentucky 6/11 - Pyro Mine) and Kentucky 9/14 coal from the Colonial Mine were used. The effect of pyrite addition to the Pyro Mine coal was investigated. No solvent quality or coking problems were experienced in the Merriam runs. Significant changes in solvent composition were apparent and equilibrated solvent samples were returned to Wilsonville for solvent quality testing.

  10. Proton resonance spectroscopy. Quarterly technical progress report, December 1992--November 1995

    International Nuclear Information System (INIS)

    Work on chaos in the low-lying levels of nuclei has continued on several fronts. The major effort has been study of the 29Si(p,γ) reaction with the goal of establishing a complete level scheme for 30P and analyzing the eigenvalue fluctuations for evidence of chaos. These measurements are in progress, and the current status is described. A related topic is the search for different signatures of chaos which do not require the extremely high degree of completeness and purity necessary for eigenvalue analyses; those efforts are discussed in Sections 2 and 3. The possibility of studying both parity violation and time-reversal invariance violation with charged particle resonances has been explored by performing calculations using experimentally measured resonance parameters. Large enhancements are indeed available; the results are discussed in Sections 4 and 5. Preparations for an experimental study of parity violation using these techniques are ongoing. An undergraduate project searching for experimental evidence of a parity dependence of level density is discussed in Section 6. A number of improvements to the operation of the TUNL KN accelerator have been implemented in the past three years. These are described in Section 7

    This report summarizes the progress of the Solvent Refined Coal (SRC) Project by the Pittsburg and Midway Coal Mining Co. for the Department of Energy for the period January 1, 1979 to March 31, 1979. Activities included the operation and modification of the Solvent Refined Coal Pilot Plant at Fort Lewis, Washington; the Process Development Unit P-99 at Harmarville, Pennsylvania; and research at Merriam Laboratory in Merriam, Kansas. The Pilot Plant processed Powhatan No. 5 Coal in the SRC-II mode of operation studying the effect of coal particle size and system temperature on coal slurry blending and the effect of carbon monoxide concentration in the reaction feed gas on process yields. January and February were spent completing installation of a fourth High Pressure Separator on Process Development Unit P-99 to better simulate operating conditions for the proposed Demonstration Plant. During March, one run was completed at P-99 feeding Pittsburgh Seam Coal from the Powhatan No. 5 Mine. Merriam investigations included a study of the effect of iron containing additives on SRC-I operation, the addition of carbon monoxide to the feed gas, utilization of a hydrogenated solvent (Cresap process solvent) in the SRC-I mode under both normal and short residence time operating conditions, and development of a simulated distillation technique to determine the entire boiling range distribution of product oils.

    United States industry has a critical need for materials that are lightweight, strong, tough, corrosion resistant and capable of performing at high temperatures; such materials will enable substantial increase in energy efficiency and reduction in emissions of pollutants. Continuous fiber ceramic composites (CFCCs) are an emerging class of materials which have the potential for the desired combination of properties to meet the industrial needs. A $10 billion annual market has been estimated for CFCC products by the year 2010, which equates to over 100,000 industrial sector jobs. The CFCC program began in the spring of 1992 as a three-phase 10-year effort to assess potential applications of CFCC materials, develop the necessary supporting technologies to design, analyze and test CFCC materials, conduct materials and process development guided by the applications assessment input, fabricate test samples and representative components to evaluate CFCC material capabilities under application conditions, and analyze scaleability and manufacturability plus demonstrate pilot-scale production engineering. DOE awarded 10 Phase I cooperative agreements to industry-lead teams plus identified generic supporting technology projects. This document highlights the broad progress and accomplishments on these contracts and support technology projects during Phase I.

    1996-06-01

    This research project is concerned with the design, synthesis and study by photochemical and spectroscopic methods of complex molecular devices that mimic some important aspects of photosynthetic electron and energy transfer. Properly engineered molecules of this type can functionally mimic photosynthetic light harvesting (singlet-singlet energy transfer between chromophores), photoprotection from light-initiated singlet oxygen damage (triplet-triplet energy transfer from chlorophylls to carotenoid polyenes), and, most importantly, photoinduced multistep electron transfer to generate charge-separated states that preserve some of the photon energy as chemical potential. During the last three years, progress has been made on several fronts, all of which are related to the overall goal. A biomimetic system based on carotenoid-porphyrin-quinone triads has been constructed that demonstrates photoinduced transmembrane charge separation which in turn drives transmembrane proton transfer. Another investigation has focused on the use of proton transfer reactions to stabilize the initial products of photoinduced electron transfer and thereby increase the yield of long-lived charge separation. A third study has investigated the influence of rigid molecular geometries and short donor-acceptor separations on photoinduced electron transfer reactions. Finally, generation and quenching of singlet molecular oxygen by chlorophyll aggregates has been studied. All four studies are described and results are discussed.

    International Nuclear Information System (INIS)

    In Our Proposal ''Ion Rings for Magnetic Fusion'' of January 6, 1993, Stage I of our Proposed Program plan (the 12 months) consisted of the following tasks: Experiments on the existing ion ring experimental system IREX to test a new magnetically-controlled anode plasma source (MAP) for the ion beam diode injector; numerical simulations of ion ring formation to optimize design parameters for the field reversed ion ring experiment (FIREX) to be built and operated in Stage II; and designing the power supply for the FIREX injector and the magnetic field system using results for A and B. During the past 7 1/2 months our work has progressed according to the above plan. In addition to testing the MAP diode on IREX we have tested the EMFAPS (evaporating metal film anode plasma source) anode on the Sandia National Laboratories funded LION pulsed power generator. As a result of these experiments, described this paper, we have arrived at the conclusion that EMFAPS anode for the ion at present because the MAP diode beam diode injector is our preferred choice for is still in an early stage of development

    The conceptual design for a three oven-dry ton per day biomass fermentation facility is presented. Based on a detailed evaluation of emerging technologies and improved modifications of current technology, a mainstream process and optional unit operation and sub-systems have been selected which offer the greatest probability of success for an economic and technically feasible process for production of ethanol from lignocellulosic biomass (hardwoods, wheat straw, corn stover, etc.). The design is intentionally flexible as stipulated in the contractual objectives. Recommendations of equipment is premised on its versatility for multi-functional application, thus enabling investigation to assess a number of process configurations while adhering to a cost-effective capital investment in the process development unit. A specific criterion in selection has been to facilitate the generation of engineering data based on the application of the results of research contractors of the US Department of Energy. The design for a total system includes the facility for evaluation of three pretreatment options, for isolation of by-product streams, for evaluation of acid and enzymatic hydrolysis, sugar concentration, alternative fermentation technologies and alcohol recovery for production of absolute ethanol. In order to maintain capital costs for the PDU within reasonable limits monitoring of by-product streams will be undertaken and, for unit operation with high potential (such as membrane concentration of ethanol) but which are in early stages of development smaller-scale equipment and/or plumbing taps for late addition of full-scale (i.e., PDU-scale) equipment is recommended. The rationale, and process economics, upon which the recommendations are based is detailed, as is a study of biomass feedstock availability.

  17. The thermionic fuel element verification program: Technical progress and future plans

    International Nuclear Information System (INIS)

    The goal of the Thermionic Fuel Element Verification Program (TFEVP) is to demonstrate the technological readiness of a Thermionic Fuel Element (TFE) suitable for use as the basic element in a thermionic reactor having an electric power output in the 0.5- to 5-MWe range and a full-power life of seven years. The TFEVP has made significant progress in developing components capable of withstanding the required neutron fluence (4x1022 n/cm2, E>0.1 MeV) and the required burnup (5.3%). Technology developed under the TFEVP also supports the 5- to 40-kWe thermionic systems currently of interest to the Strategic Defense Initiative Organization and the United States Air Force. The fast-neutron flux in certain 5- to 40-kWe systems is up to a factor of five less than that in 0.5- to 5-MWe system. Component technology that has been developed for 0.5- to 5-MWe systems will thus be suitable for use in long-life, high-performance, 5- to 40-kWe systems. Components that are being developed by the TFEVP include insulator seals, sheath insulators, fueled emitters, cesium reservoirs, and interconnective TFE components. In addition, the TFEVP has created a preliminary 2-MWe-system design and is presently evaluating converter performance under various conditions. Prototypic TFEs are also being tested. The TFEVP has encountered and surmounted problems in developing and testing long-life TFEs. The emphasis of the US thermionic reactor development effort is shifting to the development of a 40-kWe thermionic space nuclear power supply. The TFEVP will be closed out by the end of fiscal year 1994, with the close-out optimized for yielding the maximum overall program benefit-to-cost ratio. Information gained during the close-out will be very useful to the development of the 40-kWe thermionic system

  18. Theory of high-energy-collision processes. Technical progress report, January 1-December 31, 1981

    International Nuclear Information System (INIS)

    Progress is described in the following areas: (1) several years ago, surprisingly simple expressions were obtained for the differential cross sections of e+e- → μ+μ-γ and e+e- → e+e-γ at high energies. Such simple expressions were generalized to twelve other similar radiative processes in QED and QCD. Afterwards, it was found that these results can be derived easily with the help of helicity amplitudes. This method is being investigated for many other radiative processes; (2) in the two-dimensional Ising model, the horizontal and vertical interaction energies are usually taken to be different. When this idea of different interactions in different directions is applied to the Z2 lattice gauge theory in four dimensions, a limiting case is found which is exactly solvable. Contrary to numerical calculations at the symmetry point, the phase transition is found to be of second order; (3) on the subject of supersymmetry, general helicity and spin sum rules were obtained for massless and massive supermultiplets, and a functional integral approach was found as a natural setting for Witten's criterion for the occurrence of dynamic symmetry breaking of supersymmetry. A systematic and exhaustive analysis of explicit soft breaking of global supersymmetry has also been carried out using the methods of superfields; (4) the renormalization of the massless Thirring model in the neighborhood of g = -π/2 was studied. The results are consistent with those found previously by placing the model on a lattice; and (5) in studying the effect of laboratory temperature on scattering processes, it was found that transport phenomena play an important role. As a preparation for this study, an exactly solvable case of the nonlinear Boltzmann equation has been found and studied

    1981-01-01

    This report summarizes the progress of the Solvent Refined Coal (SRC) project at the SRC Pilot Plant in Fort Lewis, Wahsington, and the Process Development Unit (P-99) in Harmarville, Pennsylvania. After the remaining runs of the slurry preheater survey test program were completed January 14, the Fort Lewis Pilot Plant was shut down to inspect Slurry Preheater B and to insulate the coil for future testing at higher rates of heat flux. Radiographic inspection of the coil showed that the welds at the pressure taps and the immersion thermowells did not meet design specifications. Slurry Preheater A was used during the first 12 days of February while weld repairs and modifications to Slurry Preheater B were completed. Two attempts to complete a material balance run on Powhatan No. 6 Mine coal were attempted but neither was successful. Slurry Preheater B was in service the remainder of the quarter. The start of a series of runs at higher heat flux was delayed because of plugging in both the slurry and the hydrogen flow metering systems. Three baseline runs and three slurry runs of the high heat flux program were completed before the plant was shut down March 12 for repair of the Inert Gas Unit. Attempts to complete a fourth slurry run at high heat flux were unsuccessful because of problems with the coal feed handling and the vortex mix systems. Process Development Unit (P-99) completed three of the four runs designed to study the effect of dissolver L/D ratio. The fourth was under way at the end of the period. SRC yield correlations have been developed that include coal properties as independent variables. A preliminary ranking of coals according to their reactivity in PDU P-99 has been made. Techniques for studying coking phenomenona are now in place.

    In the United States, more than 20 billion barrels of salt water are produced each year during oilfield operations. A tremendous economic incentive exists to reduce water production if that can be accomplished without significantly sacrificing hydrocarbon production. This three-year research project had three objectives. The first objective was to identify chemical blocking agents that will (a) during placement, flow readily through fractures without penetrating significantly into porous rock and with screening out or developing excessive pressure gradients and (b) at a predictable and controllable time, become immobile and resistant breakdown upon exposure to moderate to high pressure gradients. The second objective was to identify schemes that optimize placement of the above blocking agents. The third objective was to explain why gels and other chemical blocking agents reduce permeability to one phase (e.g., water) more than that to another phase (e.g., oil or gas). The authors also wanted to identify conditions that maximize this phenomenon. This project consisted of three tasks, each of which addressed one of the above objectives. This report describes work performed during the third and final period of the project. During this three-year project, they: (1) Developed a procedure and software for sizing gelant treatments in hydraulically fractured production wells; (2) Developed a method (based on interwell tracer results) to determine the potential for applying gel treatments in naturally fractured reservoirs; (3) Characterized gel properties during extrusion through fractures; (4) Developed a method to predict gel placement in naturally fractured reservoirs; (5) Made progress in elucidating the mechanism for why some gels can reduce permeability to water more than that to oil; (6) Demonstrated the limitations of using water/oil ratio diagnostic plots to distinguish between channeling and coning; and (7) Proposed a philosophy for diagnosing and attacking water

    Energy Technology Data Exchange (ETDEWEB)

    1994-01-01

    The purpose of this contract is to develop a process for converting light alkane gases to methyl chloride via oxyhydrochlorination using highly selective, stable catalysts in fixed-bed reactors designed to remove the large amount of heat generated, so as to control the reaction temperature. Further, the objective is to obtain the engineering data base necessary for developing a commercially feasible process and to evaluate the economics of the process. Several key technology areas were evaluated this quarter. The catalyst definition effort focused on the determination of the role of the Li and La promoters that have been found to be useful in enhancing Cu based oxyhydrochlorination of methane catalysts. Initial experiments show that the La acts to provide a much more active catalyst than the Cu only case. The role of the Li is ambiguous at this point. The Li enhances the stability of the La promoted catalyst, but gives only marginal improvement by itself This work will be continued, with additional emphasis on the analysis of the catalysts to determine the structural role that the promoters may play. The separation unit operation definition made significant progress by demonstrating in a laboratory system that a process solvent may be used to remove the product CH{sub 3}Cl from the reactor effluent stream. To date the data has been qualitative, but clear. Work will continue to gather the information possible in the laboratory to help with PDU design. An extensive amount of testing was performed on the chosen process solvent, Multitherm. A comprehensive review of all the thermal testing and associated FTIR, UV/VIS, and physical property testing is included in this report. This work shows that Multitherm should give the desired stability and solubility that are necessary to make the separation unit operation successful.

    International Nuclear Information System (INIS)

    This report summarizes the work carried out at the Nuclear Physics Laboratory of the University of Colorado during the period November 1, 1975 to November 1, 1976. The low energy nuclear physics section is dominated by light-ion reaction studies which span a wide range. These include both two-neutron and two-proton transfer reactions, charge exchange and inelastic scattering, as well as single nucleon transfer reactions. The nuclei studied vary widely in their mass and characteristics. These reaction studies have been aided by the multi-use scattering chamber which now allows the energy-loss-spectrometer beam preparation system (beam swinger) to shift from charged particle studies to neutron time-of-flight studies with a minimum loss of time. The intermediate energy section reflects the increase in activity accompanying the arrival of LAMPF data and the initiation of (p,d) studies at the Indiana separated-sector cyclotron. The nucleon removal results provided by the π beam at EPICS previous to completion of the spectrometer have shown that nuclear effects dominate this process, so that the widely used free interaction picture is inadequate. The section entitled ''Other Activities'' reveals continuing activities in new applications of nuclear techniques to problems in medicine and biology. Reactions important to astrophysics continue to be investigated and our trace-element program remains at a high level of activity. The theoretical section reports new progress in understanding magnitudes of two-step reactions by inclusion of finite-range effects. A new finite-range program which is fast and economical has been completed. Intermediate energy results include calculations of π-γ angular correlations, low energy π-nucleus interactions, as well as (p,d) and nucleon scattering calculations for intermediate energies

  5. Final Technical Progress Report Long term risk from actinides in the environment: Modes of mobility; FINAL

    International Nuclear Information System (INIS)

    The key source of uncertainty in assessing actinide mobility is the relative importance of transport by: (1) wind erosion, (2) water erosion, and (3) vertical migration. Each of these three processes depends on several environmental factors and they compete with one another. A scientific assessment of the long-term risks associated with actinides in surface soils depends on better quantifying each of these three modes of mobility. The objective from our EMSP study was to quantify the mobility of soil actinides by wind erosion, water erosion, and vertical migration at three semiarid sites where actinide mobility is a key technical, social and legal issue. This EMSP project was the first to evaluate all three factors at a site. The approach has been to investigate both short- and long-term issues based on field and lab studies and model comparisons. Our results demonstrate the importance of incorporating threshold responses into a modeling framework that accounts for environmental factors and natural disturbances that trigger large changes in actinide mobility. The study measured erosional losses of sediment and fallout cesium (an actinide analogue) from field plots located near WIPP in 1998. The results highlight the large effect of burning as a disturbance on contaminant transport and mobility via runoff and erosion. The results show that runoff, erosion, and actinide transport are (1) strongly site specific-differences in radionuclide transport between WIPP and Rocky Flats differed by a factor of twelve because of soil and vegetation differences, and (2) are strongly impacted by disturbances such as fire, which can increase runoff, erosion, and actinide transport by more than an order of magnitude. In addition, a laboratory experiment using soil columns was conducted to investigate the vertical transport of contaminants in sandy soils. Nine columns of soil collected from the vicinity of the WIPP site were prepared. The column consisted of a piece of PVC pipe 20 cm

    The work accomplished during the period covered in this technical progress report demonstrates the importance, interest, and necessity of a distribution study of marine birds in the Georges Bank area on a national and international scale. Cooperation was extended by the U.S. National Marine Fisheries Service, U.S. Fish and Wildlife Service, U.S. Coast Guard, and by the Canadian Wildlife Service, Halifax, N.S., AltantNIRO, Kaliningrad, USSR, and Federal Republic of Germany. Two sampling methods, fixed-area and total bird counts, were effectively employed, which allow comparable data bases with marine bird distribution information being collected in the North Pacific, Bering and Chukchi Seas (Outer Continental Shelf Energy Assessment Program), and in the North Atlantic and Canadian Arctic (CWS and The Seabird Group). A marine bird data retrieval bank is being developed for MBO seabird data at the USFWS Migratory Bird and Habitat Research Laboratory. A food habits bibliography and prey item/bird species summary table for marine birds in the western North Atlantic has been prepared from existing literature. Unpublished NMFS data on zooplankton/ichthyoplankton, and ground fish is being made available for possible correlations in distribution of selected prey items with bird species.

  13. Feed-in tariffs versus quotas: how to promote renewable s and stimulate technical progress for cost decrease?

    International Nuclear Information System (INIS)

    Incentive schemes for the development of renewable energy sources may focus on quantities (defining national targets and setting up bidding systems, or quota systems providing for green certificate trading), or they may focus on prices (feed-in tariffs). Whatever the system chosen, the role of the public authorities is quite specific: to stimulate technical progress and speed up the technological learning processes so that ultimately renewable energy technologies will be able to compete with conventional technologies, once the environmental costs have been internalized. A comparison of instruments must thus take into account the characteristics of the innovation process and adoption conditions (uncertainties regarding cost curves, learning effects) which means also looking at dynamic efficiency criteria. The paper concludes that a system of feed-in tariffs is more efficient than a bidding system, but highlights the theoretical interest of green certificate trading which must be confirmed through practice, given the influence of market structures and rules on the performance of this type of approach.

    The objective of this program is to demonstrate the feasibility of utilizing pyrolytic oil and char as a fuel for a combustion turbine engine. This is the first phase of an extended program with the ultimate goal of commercializing a gas turbine engine and electrical generating system which is independent of petroleum-based fuels. Maximum use of existing technology and current production engine hardware (Teledyne CAE Model J69-T-29 Turbojet Engine) is being incorporated for a sequence of test evaluations rating from isolated combustor component tests to full scale engine demonstration tests. The technical goals to be achieved during the course of this project are: pyrolytic fuel characterization in terms of its properties and constituents; pyrolytic fuel combustion technology in gas turbine application in terms of pyrolytic oil atomization, quantity of char burned, emissions, performance and associated combustion system aerothermodynamics; pyrolytic fuel (oil and char slurry) handling, mixing, and storage technology; and engine materials compatibility with the the pyrolytic fuel and its combustion products. Progress achieved during the period from July 1979 through Deember 1981 in design, analysis, an project management hardware fabrication and procurement, fuel chemistry and properties, and combustor rig tests are summarized.

  16. The angular interval between the direction of progression and body orientation in normal, alcohol- and cocaine treated fruit flies.

    Anna Gakamsky

    Full Text Available In this study we characterize the coordination between the direction a fruit-fly walks and the direction it faces, as well as offer a methodology for isolating and validating key variables with which we phenotype fly locomotor behavior. Our fundamental finding is that the angular interval between the direction a fly walks and the direction it faces is actively managed in intact animals and modulated in a patterned way with drugs. This interval is small in intact flies, larger with alcohol and much larger with cocaine. The dynamics of this interval generates six coordinative modes that flow smoothly into each other. Under alcohol and much more so under cocaine, straight path modes dwindle and modes involving rotation proliferate. To obtain these results we perform high content analysis of video-tracked open field locomotor behavior. Presently there is a gap between the quality of descriptions of insect behaviors that unfold in circumscribed situations, and descriptions that unfold in extended time and space. While the first describe the coordination between low-level kinematic variables, the second quantify cumulative measures and subjectively defined behavior patterns. Here we reduce this gap by phenotyping extended locomotor behavior in terms of the coordination between low-level kinematic variables, which we quantify, combining into a single field two disparate fields, that of high content phenotyping and that of locomotor coordination. This will allow the study of the genes/brain/locomotor coordination interface in genetically engineered and pharmacologically manipulated animal models of human diseases.

    The adverse effects of prenatal alcohol consumption have long been known; however, a formal description and clinical diagnosis of these effects was not introduced until 1973. Since then, the distinction of the wide range of effects that can be induced by prenatal alcohol exposure, and, consequently, the terminology to describe these effects has continued to evolve. Although much progress has been made in understanding the consequences of prenatal alcohol exposure, challenges still remain in p...

    Michigan Technological University has demonstrated major inroads in establishing the viability of utilizing aluminum smelting by-product waste materials in lightweight concrete product applications. The research identified key elements of producing various forms of lightweight concrete products through utilizing various procedures and mixture components with the by-product materials. A process was developed through pilot plant testing that results in additional aluminum recovery at finer sizes, a clean returnable salt product through spray drying technology, and a low-salt-content oxide product with enough aluminum metal content that it can be used to form lightweight cementitious mixtures. Having three distinct products aids in generating favorable process economics. Revenue projections from aluminum recovery and salt recovery are enough to cover processing costs and create a cost-free oxide product to market for lightweight concrete applications. This supply side commercialization strategy offers aluminum by-product recyclers a potentially no cost product, which has been demonstrated through this project to create desirable and marketable lightweight concrete products of various forms. Environmental benefits to the public are tremendous. At best, all dross and salt cake materials have the potential to be completely recycled and utilized. At worst, disposal sites would see a reduced amount of material: a post processed oxide product with little salt and no hydrogen sulfide or ammonia gas generating capability, which, if isolated from high alkali conditions, would pose no reactivity concerns. The US aluminum industry has historically, along with the steel industry, been a leader in recycling metal. The findings from this project, increased metal recovery, improved salt recycling, and demonstrated end uses for oxide residues, will go a long way in helping the aluminum industry obtain 100% material utilization and zero discharge.

    During the present contract period Phaedrus has begun operation as a true tandem mirror. This was accomplished by achieving the rf sustained mode in which the plug densities were built up by a combination of central cell gas puffing and plug ICRH following stream gun turn off. It was demonstrated that the tandem mirror plasma could be sustained by plug ICRH for up to 1 msec following decay of the external plasma. In this mode plasma characteristics were no longer dominated by problems associated with a high conductivity stream gun plasma in the external region (as was the case in many previous experiments in Phaedrus). Among these problems were (1) line tying which significantly reduced instabilities in a way that would not apply to reactors and (2) low electron temperatures which had been held to approx. 20 eV

    Gerber, Mark A.; Gray, Michel J.; Thompson, Becky L.

    2013-09-23

    The U.S. Department of Energy’s Pacific Northwest National Laboratory has been conducting research since 2005 to develop a catalyst for the conversion of synthesis gas (carbon monoxide and hydrogen) into mixed alcohols for use in liquid transportation fuels. Initially, research involved screening possible catalysts based on a review of the literature, because at that time, there were no commercial catalysts available. The screening effort resulted in a decision to focus on catalysts containing rhodium and manganese. Subsequent research identified iridium as a key promoter for this catalyst system. Since then, research has continued to improve rhodium/manganese/iridium-based catalysts, optimizing the relative and total concentrations of the three metals, examining baseline catalysts on alternative supports, and examining effects of additional promoters. Testing was continued in FY 2013 to evaluate the performance and long-term stability of the best catalysts tested to date. Three tests were conducted. A long-term test of over 2300 hr duration at a single set of operating conditions was conducted with the best carbon-supported catalyst. A second test of about 650 hr duration at a single set of operating conditions was performed for comparison using the same catalyst formulation on an alternative carbon support. A third test of about 680 hr duration at a single set of operating conditions was performed using the best silica-supported catalyst tested to date.

    Markov, L.

    1988-02-01

    Discusses scientific and technical developments in Bulgarian coal mining. Until 1988, research, investigations and design were largely carried out by the Minproekt and Minstroi institutes and by higher schools of mining, usually according to a national plan determined by the Energetika association, state power and mining associations and the Association of Engineers and Technicians. After 1. January, 1988, when self-management is planned to be introduced, individual enterprises will carry out their own research, together with research institutes and other organizations. Experience acquired by the FRG, UK and France may be evaluated and advantageously applied to Bulgarian conditions. Recommendations for the future include: importing equipment and technology from abroad; basing domestic research and design around local problems and requirements; forming a central commission and several working groups to evaluate and plan research work; using experienced technical personnel for experimental introduction of new technologies; establishing experimental laboratories and mine fields in large mines and associations. 2 refs.

  6. The alcohol program

    International Nuclear Information System (INIS)

    The rationale for the launching of the Alcohol Program from sugarcane in Brazil in the mid-1970s is described as an answer to the first ''oil crisis'' as well as a solution to the problem of the fluctuating sugar prices in the international market. The technical characteristics of ethanol as a fuel are given as well as a discussion of the evolution of the cost of production, environmental and social consequences. Regarding costs, ethanol production was close to 100 dollars a barrel in the initial stages of the Program in 1980 falling rapidly due to economies of scale and technological progress to half that value in 1990, followed by a slower decline in recent years. Considering the hard currency saved by avoiding oil importation through the significant displacement of gasoline by ethanol and the decrease in the amount of external debt that the displaced oil importation was able to provide it is possible to demonstrate that the Alcohol Program has been an efficient way of exchanging dollar debt by national currency subsidies which are paid by the liquid fossil fuel users. Even with this economic gains for society, the continuity of the Program is difficult to maintain. Two solutions to this problem are discussed: internal expansion of the use of ethanol and exports to industrialized countries where it could be used as an octane enhancer. The main attractiveness of the Program - the reduction of CO2 emissions as compared to fossil fuels - is stressed, mainly as a solution for industrialized countries to fulfill their commitments with the United Nations Framework Climate Change Convention.

    Klier, K.; Herman, R.G.; Deemer, M.; Richards-Babb, M.; Carr, T.

    1995-07-01

    The objective of this research was to investigate sulfur-resistant catalysts for the conversion of synthesis gas having H{sub 2}/CO {le} 1 into C{sub 1}--C{sub 4} alcohols, especially ethanol, by a highly selective and efficient pathway, while also promoting the water gas shift reaction (WGSR). The catalysts chosen are bifunctional, base-hydrogenation, sulfur-tolerant transition metal sulfides with heavy alkali, e.g. Cs{sup +}, promoter dispersed on their surfaces. The modes of activation of H{sub 2} and CO on MoS{sub 2} and alkali-doped MoS{sub 2} were considered, and computational analyses of the thermodynamic stability of transition metal sulfides and of the electronic structure of these sulfide catalysts were carried out. In the preparation of the cesium-promoted MoS{sub 2} catalysts, a variety of preparation methods using CsOOCH were examined. In all cases, doping with CsOOCH led to a lost of surface area. The undoped molybdenum disulfide catalyst only produced hydrocarbons. Cs-doped MoS{sub 2} catalysts all produced linear alcohols, along with smaller amounts of hydrocarbons. With a 20 wt% CsOOCH/MoS{sub 2} catalyst, temperature, pressure, and flow rate dependences of the synthesis reactions were investigated in the presence and absence of H{sub 2}S in the H{sub 2}/CO = 1/1 synthesis gas during short term testing experiments. It was shown that with a carefully prepared 10 wt% CsOOCH/MoS{sub 2} catalyst, reproducible and high alcohol synthesis activity could be obtained. For example, at 295 C with H{sub 2}/CO = 1 synthesis gas at 8.3 MPa and with GHSV = 7,760 l/kg cat/hr, the total alcohol space time yield was ca 300 g/kg cat/hr (accompanied with a hydrocarbon space time yield of ca 60 g/kg cat/hr). Over a testing period of ca 130 hr, no net deactivation of the catalyst was observed. 90 refs., 82 figs., 14 tabs.

  20. Technical progress, the concept of individualized cancer treatment and the innovation of computer-assisted radiotherapy planning

    International Nuclear Information System (INIS)

    After a first step of cancerogenesis, the further development of the tumor is an individual process. At the end of this process the tumor is formed as an individual in the individual. The individuality of cancer exists on the level of organs, tissues and cells and includes an individual tumor-host relationship. Today, optimized cancer treatment requires a most precise biological characterization possible of the tumor and of the tumor-host relationship, which will provide objective information about the individual character of every tumor. Routine analysis and strict therapeutic consideration of the clinical and biological individuality of human cancer can offer real chances for the improvement of cancer treatment. A routine acquisition of individual tumor characteristics will be possible only if methods and equipment are available for the registration of suitable parameters. In this context technical innovations have an essential influence on the realization of the concept of individualized cancer treatment. With the method of flow cytophotometry and other techniques examples are given in how far the ideas of individual cancer management can be realized by introduction of new technical solutions into medical research and clinical practice. Unfortunately there is still a lack of methodology in individualizing cancer treatment. The individualization of radiotherapy is connected to an extremely high degree of technical innovations. Particularly this refers to the topometrical description of the target volume in relation to the adjacent anatomical structures and the body contour as well as the fitting of isodoses to the shape and size of the target volume. As an example of innovation of a technical solution for individual radiotherapy planning the computer-assisted radiotherapy planning system DOPSY is described. (author)

    Cassava fibrous waste is generated during starch manufactured as a solid waste used mainly for animal feeding. The process of the alcohol production from cassava fibrous waste using pectinase as a complementary enzyme in the hydrolysis process was technically and economically analyzed in this work. The addition of nutrients on the fermentation wort was also analyzed. The fibrous waste, the final fibrous residue after hydrolysis and the fermentation wort were characterized in their physical-chemistry composition and profile of sugars. The cassava fibrous waste had 80% starch, 11.5% fiber, 1.14% ash, 0,85% protein and 0.45% of the sugars. In the hydrolysis process it was obtained a conversion of 86.31 of initial starch and 80% of the total sugars yield considered as 100%. The solid fibrous residue generated after hydrolysis had 37% of the starch, 30% of total sugars and 30% of fibers in dry basis. The data indicated that 75% of the raw material was hydrolyzed. The fermentation wort had 13 deg Brix of extract and it was not necessary to concentrate it. The data showed that the maximum of alcohol is formed after 48 h of fermentation and the addition of nutrients reduced the fermentation time in 8 hours. There was not expressive difference in the fermentation yield with and without addition of nutrients. The average yield of the conversion starch to alcohol was 51.6%. The cost analysis indicated that this process is economically possible. (author)

    The Second Progress Report (referred to as H12), documenting the progress made since the publication of the first progress report in 1992, was submitted to the Atomic Energy Commission of Japan (AEC) on 26 November 1999. The objective of H12 is to demonstrate the technical feasibility and reliability of the specified disposal concept for the high-level radioactive waste (HLW) in more rigorous and transparent manner. The report was expected to provide technical basis for the repository siting and regulatory processes as assigned by the AEC's 'Guidelines on Research and Development Relating to Geological Disposal of High-Level Radioactive Waste in Japan'. The results of research and development discussed in H12 was summarized as follows: It has been confirmed that stable geological environments are widely distributed in Japan in which an engineered barrier system constructed at depth can be expected to maintain its integrity for a long period of time, and which also function as a natural barrier to retard radionuclide migration. Work in Japan and elsewhere has provided an extensive body of data and experience which allows confidence that an appropriate repository can be designed for any suitable host rock. Following site selection, the information required to support such design work and to establish a rational site development and management plan has been outlined. The long-term safety of a repository system has been evaluated by a rigorous performance assessment methodology which includes a comprehensive evaluation of uncertainties. Despite extensive uncertainty at the present stage of the Japanese program, it has been demonstrated that a HLW repository would lead to negligible doses calculated to be below the guidelines established in other countries.

    Full Text Available Chronic use of alcohol is considered to be a potential risk factor for the incidence of type 2 diabetes mellitus (T2DM, which causes insulin resistance and pancreatic β-cell dysfunction that is a prerequisite for the development of diabetes. However, alcohol consumption in diabetes has been controversial and more detailed information on the diabetogenic impact of alcohol seems warranted. Diabetes, especially T2DM, causes dysregulation of various metabolic processes, which includes a defect in the insulin-mediated glucose function of adipocytes, and an impaired insulin action in the liver. In addition, neurobiological profiles of alcoholism are linked to the effects of a disruption of glucose homeostasis and of insulin resistance, which are affected by altered appetite that regulates the peptides and neurotrophic factors. Since conditions, which precede the onset of diabetes that are associated with alcoholism is one of the crucial public problems, researches in efforts to prevent and treat diabetes with alcohol dependence, receives special clinical interest. Therefore, the purpose of this mini-review is to provide the recent progress and current theories in the interplay between alcoholism and diabetes. Further, the purpose of this study also includes summarizing the pathophysiological mechanisms in the neurobiology of alcoholism.

    The content of higher alcohols is an important physical and chemical indicator of rice wine. The factors influencing the content of higher alcohols in rice wine were raw materials, additives, yeast species, fermentation technology, downstream processing and so on. To control the content of higher alcohols in rice wine, it is critical to breeding yeast species producing higher alcohols at low level and being stable in property. It was demonstrated that inoculating yeast with high activity of lactate dehydrogenase was an effective way.%高级醇含量是成品黄酒中的重要理化指标,影响黄酒中高级醇含量的因素有:酿酒原辅料、酵母菌种、发酵工艺及后续的处理工艺等.如何选育高级醇生成量相对较低的菌种并保持菌种质量的相对稳定是控制黄酒中高级醇含量的关键因素,通过研究发现,选育乳酸脱氢酶活力很高的酵母可减少高级醇的生成.

  17. Mutagenic effect of tritium on DNA of Drosophila melanogaster: Technical progress report, December 15, 1986-July 15, 1987

    International Nuclear Information System (INIS)

    Recombinant DNA techniques were used to analyze mutants induced by either tritium or x-ray. Mutations induced at the alcohol dehydrogenase locus (Adh) in Drosophila melanogaster were first characterized by genetic complementation tests to determine if a multi-locus deletion has occurred. Mutants that are intragenic as defined by the complementation test are then placed opposite a deficiency so that the DNA from the mutant allele may be extracted and analyzed. Part I of the project is to analyze mutants induced by ionizing radiation with molecular techniques, and part II is to determine the molecular effects of these mutant phenotypes on their expression in the polypeptide produced by the mutant gene. Part III of this project consists of inducing mutants with tritiated water at the Adh locus in D. melanogaster. We have reported the development of a feeding method for exposing male D. melanogaster to tritiated water that would give a range in dose from 6.66 Gy to 26.64 Gy. This method of exposing Drosophila was used first to study a dose response curve for tritium using as a genetic endpoint the sex-linked recessive lethal test. 3 figs., 1 tab

    Two Priority One activities have received major attention during this reporting period. Application credits for HVDC systems imbedded in ac links are expected to evolve out of a system study wherein dc is introduced into a system where the breakeven criterion is not satisfied. Alternative benefits of the dc link will be quantified in an attempt to develop an expanded economic basis for HVDC systems. HVDC circuit breaker development is being examined, as there appears to be a relationship between the acceptance of multiterminal dc systems and the availability of a dc breaker. At the present time there is a large technical gap between laboratory status and field availability. Further investigation of dc interruption techniques is recommended, together with the establishment of operating criteria and design specifications. A variety of other HVDC activities was undertaken, including proposal review, contract progress report assessment, inverter commutation with series capacitor assistance, and conference planning.

  8. Progress of the radioactive waste management at the Dalat Nuclear Research Institute and the role of an IAEA technical co-operation project in this process

    International Nuclear Information System (INIS)

    At present, the main radioactive waste generator in Vietnam is the Dalat Nuclear Research Institute (DNRI). For safe management of radioactive waste generated from this nuclear center, in 1982 Soviet specialists newly constructed one combined technology system for low level radioactive waste management. The existing system consists of two main parts, a Liquid Radioactive Waste Treatment Station and a Storage/Disposal Facility. The liquid treatment station can in principle meet the needs for this nuclear center but disposal technology and storage/disposal facilities are not good enough both with respect to safety and economy, especially the storage/disposal facility placed in Dalat, the tourist city. In order to help DNRI and Vietnam to solve the radioactive waste management problem, the IAEA Technical Co-operation (TC) project VIE/9/007 was implemented in Vietnam. The facilities and IAEA experts provided under this project gradually help to develop radioactive waste management at DNRI, Vietnam. This paper outlines progress under way in the management of the radioactive waste at the Nuclear Research Institute (NRI), Dalat, Vietnam, and the role of the IAEA Technical Co-operation (TC) project in this process.

    This report summarizes the progress and accomplishments of this research project from September 1, 1989 to February 28, 1993. During this period, we have accomplished all of the primary scientific objectives of the research proposal: (1) constructed and evaluated a laser-induced fluorescence detection system that allows direct examination of the chromatographic column, (2) examined nonequilibrium processes that occur upon solute injection and elution, (3) examined solute retention in liquid chromatography as a function of temperature and pressure, (4) examined solute zone dispersion in liquid chromatography as a function of temperature and pressure, and (5) developed appropriate theoretical models to describe these phenomena. In each of these studies, substantial knowledge has been gained of the fundamental processes that are responsible for chromatographic separations. In addition to these primary research objectives, we have made significant progress in three related areas: (1) examined pyrene as a fluorescent polarity probe insupercritical fluids and liquids as a function of temperature and pressure, (2) developed methods for the class-selective identification of polynuclear aromatic hydrocarbons in coal-derived fluids by microcolumn liquid chromatography with fluorescence quenching detection, and (3) developed methods for the determination of saturated and unsaturated (including omega-3) fatty acids in fish oil extracts by microcolumn liquid chromatography with laser-induced fluorescence detection. In these studies, the advanced separation and detection techniques developed in our laboratory are applied to practical problems of environmental and biomedical significance.

    A 55-year-old man was admitted for a femur fracture; an alcohol fetor was noted on admission. The following day, the patient began to experience tremors and nervousness. Intravenous haloperidol was administered. Shortly afterwards, the patient experienced two generalized seizures and then began to experience delirium and uncontrollable agitation. The patient was diagnosed with alcohol withdrawal syndrome; high doses of intravenous midazolam were prescribed and infused. A few hours later, the patient presented signs of respiratory depression, requiring a transfer to the intensive care unit. After a review of the medical history, it was determined that the patient had been admitted on 3 previous occasions due to alcohol withdrawal and had progressed to delirium tremens after experiencing seizures. Can the risk of alcohol withdrawal syndrome and the need for prophylactic treatment be assessed on admission? Were appropriate monitoring and treatment measures employed? Would it have been possible to change his outcome? PMID:25559647

    Two long gasification tests were accomplished (66 and 72 hours of slagging operation) this quarter, and the balance of the wastewater needed for the second cooling tower (CT) test (approx. 11,000 gallons) was generated. Eleven thousand gallons of slagging fixed-bed gasifier (SFBG) wastewater were solvent extracted and ammonia stripped (AS) to nominal levels of 160 mg/1 phenol and 600 mg/1 NH/sub 3/. This wastewater is being further treated by activated sludge (AS) and granular activated carbon (GAC) processing to prepare a high quality makeup for the second CT test. Phenol mass balances indicated that > 90 pct of the phenol was stripped from the tower, indicating that previous assumptions of high levels of biodegradation were erroneous. Over 80 pct of the ammonia and about 25 pct of the methanol were also stripped. Data collected during steady state operation of the bench-scale rotating biological contractor indicate complete removal of phenolics and alcohols, and 94 pct removal of BOD. Nitrification also occurred in this unit, with over 30 pct removal of ammonia. Problems due to individual bacteria, present in the biotreated wastewater, passing through the multi-media filter and thus decreasing the carbon adsorption efficiency of the GAC system, have resulted in lower treatment rates than originally anticipated. As a result, to achieve the desired treatment, the contact time of the wastewater with the carbon in the granular activated carbon system has been increased. Since this has decreased the treatment rate, a larger carbon adsorption system has been designed and is presently being constructed.

    The overall philosophy for the ITER design has been to use established approaches through detailed analysis and to validate their application to ITER through technology R and D, including fabrication of full scale or scalable models of key components. All this R and D work has been done for ITER under collaboration among the Home Teams, with a total resource of about 660 KIUA. R and D issues for ITER-FEAT are almost the same as for the 1998 ITER design. Major developments and fabrication have been completed and tests have significantly progressed. The technical output from the R and D validates the technologies and confirms the manufacturing techniques and quality assurance incorporated in the ITER design, and supports the manufacturing cost estimates for important key cost drivers. The testing of models is continuing to demonstrate their performance margin and/or to optimize their operational use. Their realisation offers insights useful for a possible future collaborative construction activity. Valuable and relevant experience has already been gained in the management of industrial scale, cross-party ventures. The successful progress of these projects increases confidence in the possibility of jointly constructing ITER in an international project framework. The R and D present status is summarized in the following: details are given in Chapters 2 and 3. Significant efforts and resources have been devoted to the Seven Large R and D Projects which cover all the major key components of the basic machine of ITER and their maintenance tools

    The scope of the contract covers the development and evaluation of forming solar cell collector grid contacts by the MIDFILM process. This is a proprietary process developed by the Ferro Corporation which is a subcontractor for the program. The MIDFILM process attains line resolution characteristics of photoresist methods with processing related to screen printing. The surface to be processed is first coated with a thin layer of photoresist material. Upon exposure to ultraviolet light through a suitable mask, the resist in the non-pattern area cross-links and becomes hard. The unexposed pattern areas remain tacky. The conductor material is applied in the form of a dry mixture of metal and frit particles which adhere to the tacky pattern area. The assemblage is then fired to ash the photopolymer and sinter the fritted conductor powder. Effort was concentrated during this period on the establishment, optimization and identification of problem areas of the MIDFILM process. Progress is reported. (WHK)

    Kvale, T.J.

    1994-09-27

    This report describes the progress made on the research objectives during the past three years of the grant. This research project is designed to study various scattering processes which occur in H{sup {minus}} collisions with atomic (specifically, noble gas and atomic hydrogen) targets in the intermediate energy region. These processes include: elastic scattering, single- and double-electron detachment, and target excitation/ionization. For the elastic and target inelastic processes where H{sup {minus}} is scattered intact, the experimental technique of Ion Energy-Loss Spectroscopy (IELS) will be employed to identify the final target state(s). In most of the above processes, cross sections are unknown both experimentally and theoretically. The measurements will provide total cross sections (TCS) initially, and once the angular positioning apparatus is installed, will provide angular differential cross sections (ADCS).

  20. Oxygenated octane enhancers: Syngas to isobutylene. Technical progress report No. 17, April 1, 1995--June 30, 1995

    Barger, P.T.; Kurek, P.R.

    1996-01-18

    The goals of this project are to develop a catalyst and process for the conversion of syngas to isobutanol. The research will identify and optimize key catalyst and process characteristics. In addition, the commercial potential of the new process will be evaluated by an economic analysis. The effects of temperature, pressure and methanol/ethanol molar feed ratio on the performance of the 2% Pt on Zn/Mn/Zr Oxide catalyst has been evaluated in a series of pilot plant tests. Temperature has been varied from 325{degrees}C to 375{degrees}C, pressure from 30 psig to 300 psig and MeOH/EtOH ratio from 1 0/1 to 1 /1. Raising temperature increases alcohol conversion, but reduces selectivity and productivity to the desired branched C4 oxygenates. The higher pressure operation shifts the product ratio from isobutyraldehyde to isobutanol. Decreasing the feed ratio from 10/1 to 7/1 increases methanol conversion as well as selectivity to each of the iC4 oxygenates. However, further reduction of the feed ratio to 4/1 does not give additional improvement. Based on these findings a pilot plant test at optimized conditions is planned using the 2% Pt on Zn/Mn/Zr oxide catalyst. The effects of H{sub 2}, CO and CO{sub 2} co-feeds on the performance of the cztalyst have also been evaluated using the reference catalyst. Co-feeding H{sub 2} has very little effect, whereas CO has a deleterious effect. CO{sub 2} addition results in higher CO formation, but no substantial change in CO{sub 2} selectivity. Therefore, it appears that the use of a CO{sub 2} recycle would not be effective for reducing the formation of carbon oxide products. A copper-lined reactor has been constructed that gives acceptable blank activity at temperatures up to 450{degrees}C and used to evaluate the activity of the 2% Pt on Zn/Mn/Zr oxide catalyst for methanol-only conversion. At temperatures greater than 350{degrees}C, minimal branched C4 oxygenates are formed. Instead, the primary products are CO and CO{sub 2}.

  1. Projects at the Western Environmental Technology Office. Quarterly technical progress report, July 1, 1995--September 30, 1995

    International Nuclear Information System (INIS)

    The goal of this project is to demonstrate the technical and economic feasibility of commercializing a biotechnology that uses plants to remediate soils, sediments, surface waters, and groundwaters contaminated by heavy metals and radionuclides. This technology, known as phytoremediation, is particularly suited to remediation of soils or water where low levels of contaminants are widespread. Project objectives are to provide an accurate estimate of the capability and rate of phytoremediation for removal of contaminants of concern from soils and groundwaters at Department of Energy (DOE) sites and to develop data suitable for engineering design and economic feasibility evaluations, including methods for destruction or final disposition of plants containing contaminants of concern. The bioremediation systems being evaluated could be less expensive than soil removal and treatment systems, given the areal extent and topography of sites under consideration and the investment of energy and money in soil-moving and -treating processes. In situ technology may receive regulatory acceptance more easily than ex situ treatments requiring excavation, processing, and replacement of surface soils. In addition, phytoremediation may be viable for cleanup of contaminated waters, either as the primary treatment or the final polishing stage, depending on the contaminant concentrations and process economics considerations

    Significant quantities of wood residue fuels are presently being used in industrial steam generating facilities. Recent studies indicate that substantial additional quantities of wood residue fuels are available for energy generation in the form of steam and/or electricity. A limited data base on the combustion characteristics of wood residue fuels has resulted in the installation and operation of inefficient combustion systems for these fuels. This investigation of the combustion characteristics of wood residue fuels was undertaken to provide a data base which could be used to optimize the combustion of such fuels. Optimization of the the combustion process in industrial boilers serves to improve combustion efficiency and to reduce air pollutant emissions generated in the combustion process. This report presents data on the combustion characteristics of Douglas Fir planer shavings. The data were obtained in a pilot scale combustion test facility at Oregon State Univerisity. Other technical reports present data on the combustion characteristics of: Douglas Fir bark, Red Alder sawdust, Red Alder bark, Ponderosa pine bark, Hemlock bark, and Eastern White Pine bark. An executive summary report is also available which compares the combustion characteristics of the various fuel species.

    Research in this project centers upon developing a new approach to the direct liquefaction of coal to produce an all-distillate product slate at a sizable cost reduction over current technology. The approach integrates all aspects of the coal liquefaction process including coal selection, pretreatment, coal swelling with catalyst impregnation, coal liquefaction experimentation, product recovery with characterization, alternate bottoms processing, and a technical assessment including an economic evaluation. The project is being carried out under contract to the United States Department of Energy. On May 28, 1992, the Department of Energy authorized starting the experimental aspects of this projects; therefore, experimentation at Amoco started late in this quarterly report period. Research contracts with Auburn University, Pennsylvania State University, and Foster Wheeler Development Corporation were signed during June, 1992, so their work was just getting underway. Their work will be summarized in future quarterly reports. A set of coal samples were sent to Hazen Research for beneficiation. The samples were received and have been analyzed. The literature search covering coal swelling has been up-dated, and preliminary coal swelling experiments were carried out. Further swelling experimentation is underway. An up-date of the literature on the liquefaction of coal using dispersed catalysts is nearing completion; it will be included in the next quarterly report.

    Full Text Available Shellfish aquaculture is a widespread activity in the Italian peninsula. However, only two bivalve species are mainly cultured along the coastline of that country: the Mediterranean mussel Mytilus galloprovincialis and the Manila clam Venerupis philippinarum (Ruditapes philippinarum. By contrast, just a few other mollusc species of commercial interest are scarcely reared at a small-scale level. After analysing the current status of Italian shellfish production, this paper reports and discusses the potential for culturing several different invertebrate species [i.e., the European flat oyster Ostrea edulis, the grooved carpet shell Venerupis decussata (Ruditapes decussatus, the razor clams Ensis minor and Solen marginatus, the cephalopod Octopus vulgaris, and the purple sea urchin Paracentrotus lividus] in this country. In addition, a detailed overview of the progress made in aquacultural techniques for these species in the Mediterranean basin is presented, highlighting the most relevant bottlenecks and the way forward to shift from the experimental to the aquaculture phase. Finally, an outlook of the main economic and environmental benefits arising from these shellfish culture practices is also given.

    The primary objective of this program is the advanced development of sophisticated particle beam diagnostic techniques for making space and time resolved measurements on high temperature magnetically confined plasmas. The procedure is to develop and test new techniques on small-scale laboratory experiments and then transfer the technology to mainline confinement experiments. During the period covered by this progress report the major advances were: (1) demonstrated that beam probing can provide simultaneous measurements of n, phi and T/sub e/ on plasmas when T/sub e/ is less than approximately 500 eV; (2) demonstrated simultaneous measurements of n tilde and phi tilde on tokamak geometry for frequencies below 200 kHz; (3) developed the concept of multi-element energy analyzer to provide simultaneous measurements for more than one spatial location in the plasma; and (4) carried out preliminary analysis that showed that beam probes can be implemented on complex magnetic geometries such as ATF and that beam probe system could be extended into the MeV energy range

    The sulfur heterocycle separation scheme which was described in the last progress report was evaluated for quantitative recovery of individual components. The results indicate that recoveries can range from 10% to approx. 30% depending on the structure of the compound. During this period, 23 unsubstituted sulfur-containing heterocyclic ring systems were synthesized in oder to confirm GC/MS identifications and for biological testing. The four possible 3-ring heterocycles and the thirteen possible 4-ring heterocycles were tested for mutagenic activity in the histidine reversion (Ames assay) system. One of the 3-ring isomers, naphtho(1,2-b)-thiophene, and six of the 4-ring isomers induced mutations in Salmonella test strains. One of these compounds, phenanthro(3,4-b)thiophene, displayed approximately the same mutagenic activity as benzo(a)pyrene. A two-step adsorption chromatographic procedure was developed in order to fractionate synthetic fuels into various chemical-type classes for studying the relative concentrations and mutagenic activities of the various types. An SRC-II Heavy Distillate was fractionated into aliphatic hydrocarbons, polycyclic aromatic hydrocarbons, sulfur heterocycles, indoles and carbazoles, azaarenes, and amino polycyclic aromatic hydrocarbons. It was found that the amino-PAH fraction contained most of the mutagenic activity. A survey was made for compounds containing both nitrogen and sulfur heteroatoms in their structures. A number of these compounds were detected by GC using nitrogen- and sulfur-selective detection.

    Our program began on August 1, 1999. As of April 1, 2000, the progress has been in materials selection and test planning. Three subcontracts are in place (McDermott Technologies Inc. for continuous fiber reinforced ceramic tubing fabrication, Swales Aerospace for LOCA testing of tubes, and Massachusetts Institute of Technology for In Reactor testing of tubes). With regard to materials selection we visited McDermott Technologies Inc. a number of times, including on February 23, 2000 to discuss the Draft Material Selection and Fabrication Report. The changes discussed at this meeting were implemented and the final version of this report is attached (attachment 1). McDermott Technologies Inc. will produce one type of tubing: Alumina oxide (Nextel 610) fiber, a carbon coating (left in place), and alumina-yttria matrix. A potentially desirable CFCC material of silicon carbide fiber with spinel matrix was discussed. That material selection was not adopted primarily due to material availability and cost. Gamma Engineering is exploring the available tube coatings at Northwestern University as a mechanism for reducing the permeability of the tubes, and thus, will use coating as a differentiating factor in the testing of tubing in the LOCA test as well as the In-Reactor Test. The conclusion of the Material Selection and Fabrication Report lists the possible coatings under evaluation. With regard to Test Planning, the MIT and Swales Aerospace have submitted draft Test Plans. MIT is attempting to accommodate an increased number of test specimens by evaluating alternative test configurations. Swales Aerospace held a design review at their facilities on February 24, 2000 and various engineering alternatives and safety issues were addressed. The final Test Plans are not expected until just before testing begins to allow for incorporation of changes during ''dry runs.''

    1993-09-01

    As we reported in the Technical Progress Report No. 7, there are surges of electric current in the charging loop during triboelectrification of all particles. A high speed data acquisition and analysis system was developed to monitor and record the current pattern. There is no known report on such charge-discharge surges in the literature. The mechanism for it is yet to be understood. The on-line computerized electric current measurement also leads to an observation of charging effects as a function of particle feeding rate. It is shown that feed rate greatly alters particle charge. Such an effect is mostly overlooked by researchers and it could have a important role in process design where the feed rate would be maximized. The initial results for coal and mineral particles demonstrated that the average charge was lower when the feed rate was increased. Further investigation is scheduled to identify potential controlling factors, eg, the solid volume fraction and particle number density could be important process factors. The study of charging velocity and particle size was continued. It was found that particle charge was linearly dependent on the charging velocity for all samples investigated. However, the slope of this linear dependence varied for particles having different diameters. In addition, the charge-velocity relationships were dependent on feeding rates. Hence, the data discussed below include these interrelationships.

    This report summarizes the technical progress achieved during the first quarter of the ERIP project entitled, ``Laser Ultrasonic Furnace Tube Coke Monitor.`` The focus of work during this reporting period was the testing of a novel device for introducing a broad bandwidth ultrasonic pulse at the surface of a simulated furnace tube. The device employs a sacrificial stand-off composed of a fusible alloy that conforms to hot furnace tube surface upon contact. Conventional high-temperature couplants have a maximum operating temperature of about 550{degrees}C, which limits their use for contact against ethylene cracker furnace tube surfaces that typically operate at about 1000{degrees}C. In the absence of a couplant, insufficient ultrasonic energy can be transmitted from the transducer to the tube surface. By using a fusible alloy, the device efficiently couples the transducer to the hot furnace tube surface, even for rough and convex tube surfaces operating at temperatures of 1800{degrees}F and above. Initial tests confirmed the ability to resolve pulse echoes in a simulated furnace tube using a 5 MHz piezoelectric transducer with a fusible stand-off.

    The main objective of this project is the transfer of technologies, methodologies, and findings developed and applied in this project to other operators of Slope and Basin Clastic Reservoirs. This project will study methods to identify sands with high remaining oil saturation and to recomplete existing wells using advanced completion technology. The identification of the sands with high remaining oil saturation will be accomplished by developing a deterministic 3-D geologic model and by using a state of the art reservoir management computer software. The wells identified by the geologic and reservoir engineering work as having the best potential will be logged with a pulsed acoustic cased-hole logging tool. The application of the logging tools will be optimized in the lab by developing a rock-log model. The wells that are shown to have the best oil production potential will be recompleted. The recompletions will be optimized by evaluating short radius and ultra-short radius lateral recompletions. Technical progress is reported for the following tasks: Reservoir characterization; reservoir engineering; 3-D geologic modeling; pulsed acoustic logging; and technology transfer.

    The Mulled Coal process was developed as a means of overcoming the adverse handling characteristics of wet fine coal without thermal drying. The process involves the addition of a low cost, harmless reagent to wet fine coal using off-the-shelf mixing equipment. Based on laboratory- and bench-scale testing, Mulled Coal can be stored, shipped, and burned without causing any of the plugging, pasting, carryback and freezing problems normally associated with wet coal. The objectives of this project are to demonstrate that: the Mulled Coal process, which has been proven to work on a wide range of wet fine coals at bench scale, will work equally well on a continuous basis, producing consistent quality at a convincing rate of production in a commercial coal preparation plant; the wet product from a fine coal cleaning circuit can be converted to a solid fuel form for ease of handling and cost savings in storage and rail car transportation; and a wet fine coal product thus converted to a solid fuel form, can be stored, shipped, and burned with conventional fuel handling, transportation, and combustion systems. During this reporting period, virtually all of the technical activities and progress was made in the areas of circuit installation and startup operations. Work in these activity areas are described.

    The main goal of this program is to demonstrate the utility of coal extracts from the West Virginia University (WVU) extraction process as suitable base raw materials for the carbon products encompassed by the Carbon Products Consortium (CPC) team. This quarterly report covers activities during the period from April 1, 1996 through June 30, 1996. The first year of the project ended in February, 1996; however, the WVU research effort has continued on a no-cost extension of the original contract. Samples have been supplied to CPC participants so they could conduct their portions of the project as contracted through ORNL. Progress reports are presented for the following tasks: project planning and administration; consortium administration and reporting; coal extraction; technical/economic evaluation of WVU extraction process; and technology transfer. Previous work has shown that the WVU coal extraction process coupled with hydrotreatment, does have the potential for producing suitable base raw materials for carbon products. Current effort, therefore, involved the screening and evaluation of extracts produced by the WVU Group and recommending appropriate materials for scaleup for subsequent evaluation by Consortium Team members. As part of this program, the activation of the coal extraction residues was investigated for the purpose of producing a useful active carbon. A further task, which was started towards the end of the program, was to fabricate a small graphite artifact using Coke derived from coal extract as the filler and the coal extract itself as a binder. The results of these studies are summarized in this report.

    氢气作为一种清洁、高效的可持续能源,近年来得到了广泛关注。水相重整技术以生物质衍生醇类制备氢气,具有来源广泛、反应条件温和、运行成本较低等优点,相较于其他制氢方法更有优势。本文详细阐述生物质衍生醇类水相重整制氢的研究进展,同时讨论不同催化剂的反应机理。Pt 系催化剂表现出较高的氢气选择性,但是醇类转化率较低。Ni 系催化剂反应活性和转化率均较高,但仍存在氢气选择性和氢气产率较低等问题。%Hydrogen as a clean, efficient, and sustainable energy has attracted considerable attention in recent years. Hydrogen production from aqueous-phase reforming (APR) of biomass-derived alcohols is preferable to other methods because of its wide renewable resource, mild reaction conditions, and low processing cost. In this paper, the progress in the APR process of different biomass-derived alcohols for H2 production is reviewed, and the reaction mechanisms are briefly discussed for different cata-lysts. Pt-based catalysts exhibit high H2 selectivity but low conversion of the alcohols. Ni-based catalysts exhibit high activity and conversion but low H2 selectivity and yield.

  4. Human alcohol-related neuropathology.

    2014-01-01

    Alcohol-related diseases of the nervous system are caused by excessive exposures to alcohol, with or without co-existing nutritional or vitamin deficiencies. Toxic and metabolic effects of alcohol (ethanol) vary with brain region, age/developmental stage, dose, and duration of exposures. In the mature brain, heavy chronic or binge alcohol exposures can cause severe debilitating diseases of the central and peripheral nervous systems, and skeletal muscle. Most commonly, long-standing heavy alcohol abuse leads to disproportionate loss of cerebral white matter and impairments in executive function. The cerebellum (especially the vermis), cortical-limbic circuits, skeletal muscle, and peripheral nerves are also important targets of chronic alcohol-related metabolic injury and degeneration. Although all cell types within the nervous system are vulnerable to the toxic, metabolic, and degenerative effects of alcohol, astrocytes, oligodendrocytes, and synaptic terminals are major targets, accounting for the white matter atrophy, neural inflammation and toxicity, and impairments in synaptogenesis. Besides chronic degenerative neuropathology, alcoholics are predisposed to develop severe potentially life-threatening acute or subacute symmetrical hemorrhagic injury in the diencephalon and brainstem due to thiamine deficiency, which exerts toxic/metabolic effects on glia, myelin, and the microvasculature. Alcohol also has devastating neurotoxic and teratogenic effects on the developing brain in association with fetal alcohol spectrum disorder/fetal alcohol syndrome. Alcohol impairs function of neurons and glia, disrupting a broad array of functions including neuronal survival, cell migration, and glial cell (astrocytes and oligodendrocytes) differentiation. Further progress is needed to better understand the pathophysiology of this exposure-related constellation of nervous system diseases and better correlate the underlying pathology with in vivo imaging and biochemical lesions

  5. Exotic atoms. Technical progress report

    International Nuclear Information System (INIS)

    The experiments use a variety of hydrogen isotopic mixtures to form solid targets for muons to produce muonic hydrogen isotope atoms that escape into vacuum. The method relies on transfer of the muon from a proton to either a deuteron or a triton. The resulting muonic deuterium or muonic tritium will not immediately thermalize because of the very low elastic cross sections (RT effect), and are emitted from the surface of the layer. A second solid hydrogen isotopic target is produced downstream on which the muonic hydrogen atom can react. Measurements which detect decay electrons, muonic x-rays, and fusion products have been used to study the processes of energy dependence of transfer, production rates, and muon molecular formation. The processes include muon catalyzed fusion of muonic tritium with deuterium which is the most possible candidate for energy production fusion. Our interest is the nuclear physics reaction rates and to use the muonic hydrogen isotopes in vacuum for energy level measurements. The method uses time of flight and is reminiscent of double scattering experiments. Two other experiments are in the development stages. First to measure the energy dependence of the Ramsauer-Townsend cross section in tritium where it has not been measured. The measurements would be compared to deuterium and calculations. Second, kaonic atoms, hypernuclei, and kaon-nucleon scattering at DAPHNE

    OAK-B135 This NERI project, originally started as the Secure Transportable Autonomous Light Water Reactor (STAR-LW) and currently known as the International Reactor Innovative and Secure (IRIS) project, had the objective of investigating a novel type of water-cooled reactor to satisfy the Generation IV goals: fuel cycle sustainability, enhanced reliability and safety, and improved economics. The research objectives over the three-year (1999-2002) program were as follows: First year: Assess various design alternatives and establish main characteristics of a point design; Second year: Perform feasibility and engineering assessment of the selected design solutions; Third year: Complete reactor design and performance evaluation, including cost assessment These objectives were fully attained and actually they served to launch IRIS as a full fledged project for eventual commercial deployment. The program did not terminate in 2002 at the end of the NERI program, and has just entered in its fifth year. This has been made possible by the IRIS project participants which have grown from the original four member, two-countries team to the current twenty members, nine countries consortium. All the consortium members work under their own funding and it is estimated that the value of their in-kind contributions over the life of the project has been of the order of $30M. Currently, approximately 100 people worldwide are involved in the project. A very important constituency of the IRIS project is the academia: 7 universities from four countries are members of the consortium and five more US universities are associated via parallel NERI programs. To date, 97 students have worked or are working on IRIS; 59 IRIS-related graduate theses have been prepared or are in preparation, and 41 of these students have already graduated with M.S. (33) or Ph.D. (8) degrees. This ''final'' report (final only as far as the NERI program is concerned) summarizes the work performed in the first four years of IRIS, from October 1999 to October 2003. It provides a panoramic of the project status and design effort, with emphasis on the current status, since two previous reports have very extensively documented the work performed, from inception to early 2002.

    Nineteen catalysts were prepared by either (a) evaporation of metal nitrate-citric acid solutions; (b) coprecipitation of nitrates with carbonates; (c) mechanical blending of the metal oxide (or nitrate) powders or (d) modification of commercial methanol synthesis catalysts. Fourteen catalysts were tested in either the Berty gradientless reactor or the plug-flow reactor. Previously reported selectivities to liquid products were determined with a more refined gas chromatographic system, show that C/sub 4/-C/sub 9/ HC were also present in the liquid product in addition to the alcohols. A sample of liquid product recovered from a 100 hour test made with a CuZn/sub 0/ /sub 125/CrCoK/sub 0/ /sub 11/ catalyst was analyzed by GC and found to contain 55.9 wt % C/sub 1/-C/sub 6/ linear alcohols, 33.0% C/sub 1/-C/sub 7/ aldehydes, 9.2% C/sub 5/-C/sub 9/ paraffins and 1.9% unidentified oxygenates. A preliminary techno-economic assessment of three potential synthesis reactor systems - liquid-fluidized, multi-tube, jacketed fixed-bed or adiabatic fixed-bed - was made which indicated that there are significant captial cost and operating cost savings associated with the use of a liquid-fluidized reactor system.

    2016-08-01

    Alcoholic hepatitis is an acute form of alcoholic liver disease with variable severity that develops in patients who usually have a history of prolonged and recent alcohol abuse. The diagnosis is clinical and depends on history, physical examination, and laboratory derangements. Liver biopsy is diagnostic but not universally performed, and noninvasive diagnostic modalities are under development. Scoring systems are used to assess severity of disease, predict mortality, and guide decisions for initiation of specific therapies. The natural history and long-term outcomes of alcoholic hepatitis, including recurrence, progression to cirrhosis, and mortality, vary and depend partly on abstinence from alcohol use. PMID:27373612

    The principal objective of the Central Vacuum Unit (CVU) CO{sub 2} Huff-n-Puff (H-n-P) project is to determine the feasibility and practicality of the technology in a waterflooded shallow shelf carbonate environment. The results of parametric simulation of the CO{sub 2} H-n-P process, coupled with the CVU reservoir characterization components will be used to determine if this process is technically and economically feasible for field implementation. The technology transfer objective of the project is to disseminate the knowledge gained through an innovative plan in support of the Department of energy`s (DOE) objective of increasing domestic oil production and deferring the abandonment of shallow shelf carbonate reservoirs. Texaco Exploration and Production Inc`s. (TEPI) mid-term plans are to implement a full-scale miscible CO{sub 2} project in the CVU. TEPI concluded all of the tasks associated with the First Budget Period by October, 1995. The DOE approved the TEPI continuation application. Budget Period No. 2 is in progress. Initial injection of CO{sub 2} began in November, and after a short shut-in period for the soak, the well was returned to production in late December, 1995. This report, covers TEPI`s efforts at history matching the results of the field demonstration. Costs and economics of the work are presented. The majority of effort during the fourth quarter has revolved around the selection of a new project site and refinement of the demonstration design and well selection.

  20. Humic substances in performance assessment of nuclear waste disposal: Actinide and iodine migration in the far-field. Third technical progress report

    International Nuclear Information System (INIS)

    The present report describes progress within the third and final year of the EC-project 'Humic Substances in Performance Assessment of Nuclear Waste Disposal: Actinide and Iodine Migration in the Far-Field'. The work conducted within the present project builds on a number of previous activities/project supported by the Commission. It finds its continuation within different EC FP 6 instruments and also provides for additional continued cooperation through network structures resulting from the broad cooperation within the project. Without being a formal requirement of the Commission or co-funding bodies, this report documents results in great technical detail and makes the results available to a broad scientific community. The report contains an executive summary written by the coordinator. More detailed results are given as individual contributions in the form of 12 annexes. Not all results are discussed or referred to in the executive summary report and thus readers with a deeper interest also need to consult the annexes. The overall objectives were to generate knowledge about the impact of humic substances on the migration of actinides and iodine in the far-field of a nuclear waste repository. In the beginning, focus was rather on the potential enhancement due to humic colloid mediated radionuclide transport. Thereby, sources, inventory, stability and mobility of dissolved humic substances in their colloidal form formed a key topic. Other key topics were the interaction with actinides and iodine, transport studies under near-natural conditions in the laboratory, rationalization of knowledge in models and application to three migration cases for visualization of the overall outcome. Changes relative to the original objectives were given by moving emphasis of natural chemical analogue studies from the question of kinetic exchange constants for different inventories in natural and laboratory systems to the study of anthropogenic actinide contaminants in the Irish Sea

    This paper analyses the quest for technological progress in China, a large, semi-industrialized, socialist developing country. In the introduction, it is argued that international income convergence is not an automatic product of market forces. Therefore, the path of technological progress in a less advanced country is dependent on its bsorptive capacity, which can be enhanced by the development of an effective national innovation system. The specific meaning attached to key terms such as tec...

    Purpose is to help managers approach their responsibilities proactively, so that they can anticipate problems and take actions to alleviate or eliminate those problems. Continuous performance improvement, the philosophy behind total quality management, requires working cooperatively to do a little better each day. The most effective tools are working through a closed set of 9 methods: setting expectations, charting, defining indicators and standards, collecting and logging data, converting data to information, organizing and presenting information, reviewing status and progress, self-management, and appraising. In addition, there are 8 rules: focus on what you can do, supply physical evidence of progress, pay attention to detail, inspect (don`t expect), review progress routinely and frequently, face ``success/fail`` squarely, communicate crisply, and conduct honest, open appraisals. Scope and plans of the draft research plan (study areas) are described.

    Summary of progress since last CMS week. Ten years of construction work have been completed. CMS is closed, in very close to the ideal low luminosity configuration, and performed well in the first tests with LHC beam. Behind this encouraging news is the story of a summer of intense commitment by many teams (from the collaboration and 3 CERN departments) working together, against the clock and despite many minor setbacks, to ensure that the experiment was ready to play a leading role in the excitement of September 10. Following beampipe bakeout and refill with pure neon, a magnificent effort by the ECAL group and the pt 5 technical crew made it possible to install and commission all 4 ECAL endcap Dees before the end of August. In the shadow of this activity, the barrel and forward pixel trackers and part of the beam monitoring were installed within the vac tank. The pt 5 technical teams then succeeded in safely removing the 20t installation tables and their support blocks from beneath the already installed ...

    Construction and setup of twin laboratory gas phase reactors with in-line Gas chromatographic analysers was completed. Calibration and C.G. analysis methods development were carried out, and spreadsheet programs were written for reduction of data to interpretable results. Initial tests were carried out with pentasil zeolite ASM-5 containing very low (0.1%) levels of mercury as potential catalysts for conversion of acetylene/methanol streams to 1,1-dimethoxyethane or to C{sub 2}{sup +} alcohols, both useful as high-oxygenate gasoline blending agents. Trace levels of both types of products were observed, although the predominant products were light olefins at lower reaction temperatures and aromatics at higher temperatures. It is anticipated that less acidic zeolites and/or Zn- containing catalysts will be more active for oxygenate production. Testing of these materials is underway.

    The aim of this contract is to elucidate the mechanisms underlying adsorption and surface precipitation of flooding surfactants on reservoir minerals. The results of this study should help in controlling surfactant loss in chemical flooding and also in developing optimum structures and conditions for efficient chemical flooding processes. Adsorption of single surfactants on silica and alumina as well as the solution behavior of surfactant mixtures was studied during this quarter. The adsorption of surfactants at the solid-liquid interface was correlated with changes in interfacial behavior such as wettability and zeta potential. Surface tension was used to study interactions between surfactant mixtures in solution. Mixed micellization of sodium dodecyl sulfate and dodecyl phenoxy polyethoxylated alcohol was found to be non-ideal. Regular solution theory adequately describes the interactions. The adsorption isotherm of a cationic surfactant, tetradecyl trimethyl ammonium chloride (TTAC), on alumina was determined at two values of pH. Changes in the settling rate of alumina suspensions after TTAC adsorption were also followed to describe the evolution of the adsorbed layer. At high surface coverage it was observed that the alumina surface became hydrophilic suggesting the formation of a TTAC bilayer at the surface. Wettability of silica after adsorption of nonyl phenyl polyethoxylated alcohols (with number of polyethylene oxide groups varying from 10-40) was measured using flotation to determine the orientation of the adsorbed layer. Effect of number of ethylene oxide groups was also determined. The amount of silica floated after the nonionic surfactant adsorption was same irrespective of the ethylene oxide chain length.

  12. Acute alcohol-induced liver injury

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available Alcohol consumption is customary in most cultures and alcohol abuse is common worldwide. For example, more than 50% of Americans consume alcohol, with an estimated 23.1% of Americans participating in heavy and/or binge drinking at least once a month. A safe and effective therapy for alcoholic liver disease (ALD in humans is still elusive, despite significant advances in our understanding of how the disease is initiated and progresses. It is now clear that acute alcohol binges not only can be acutely toxic to the liver, but also can contribute to the chronicity of ALD. Potential mechanisms by which acute alcohol causes damage include steatosis, dysregulated immunity and inflammation and altered gut permeability. Recent interest in modeling acute alcohol exposure has yielded new insights into potential mechanisms of acute injury, that also may well be relevant for chronic ALD. Recent work by this group on the role of PAI-1 and fibrin metabolism in mediating acute alcohol-induced liver damage serve as an example of possible new targets that may be useful for alcohol abuse, be it acute or chronic.

  13. Bioremediation of mixed microbial mats: System development of mixed contaminants for application at the Savannah River Site. Annual technical progress report, October 1, 1995--September 30, 1996

    International Nuclear Information System (INIS)

    The fundamental objective of this project is to develop and field test the mixed microbial mat bioremediation system for decontamination of target sites at SRS. Although microbial mats have performed well in several pilot projects in the past, atypical problems and site characteristics at SRS demand special field designs. In the interest of designing a pilot and locating it at an appropriate site, the project investigators have worked closely with the technical staff at the SREL. We have concluded that the diverse characteristics of contaminations at SRS may dictate testing several pilot designs during the course of this project

    Low-temperature catalytic pretreatment is a promising approach to the development of an improved liquefaction process. This work is a fundamental study on effects of pretreatments on coal structure and reactivity in liquefaction. The main objectives of this project are to study the coal structural changes induced by low-temperature catalytic and thermal pretreatments by using spectroscopic techniques; and to clarify the pretreatment-induced changes in reactivity or convertibility of coals in the subsequent liquefaction. This report describes the progress of our work during the first quarterly period. Substantial progress has been made in the spectroscopic characterization of fresh and THF-extracted samples of two subbituminous coals and fresh samples of three bituminous coals using cross-polarization magic angle spinning (CPMAS) solid state {sup 13}C NMR and pyrolysis-GC-MS techniques. CPMAS {sup 13}C NMR and pyrolysis-GC-MS provided important information on carbon distribution/functionality and molecular components/structural units, respectively, for these coal samples. Pyrolysis-GC-MS revealed that there are remarkable structural differences in structural units between the subbituminous coals and the bituminous coals. Furthermore, significant progress has been made in the pretreatments and spectroscopic characterization of catalytically and thermally pretreated as well as physically treated Wyodak subbituminous coal, and temperature-staged and temperature-programmed thermal and catalytic liquefaction of a Montana subbituminous coal.

    Fetal alcohol syndrome (FAS) is a pattern of anomalies occurring in children born to alcoholic women. The main features of this pattern are pre and/or postnatal growth retardation, characteristic facial abnormalities, and central nervous system dysfunction, including mental retardation. Since its clinical recognition in 1973 it has progressed from an unrecognized condition to a major public health concern with exaggerated and unfounded claims as to causality and impact. This review summarizes some of the basic facts about fetal alcohol syndrome with respect to terminology, prevalence, and mechanisms, in the context of exposure risk. PMID:16611132

    During the past year of activity under DOE Grant DE-FG05-84ER40147 at Louisiana State University we have made significant progress in the data analysis, in hardware development for the Bevalac and in new experimental runs. We now have reliable longitudinal momentum distributions for 16O at three energies, 225, 170 and 360 MeV/nucleon. Combining these results with previous data shows an unexpected energy dependence of the momentum widths for A = 12--15 fragments. The widths peak at /approximately/100 MeV/nucleon projectile energy. We have also finished the analysis for 3 of the 4 energy points from the 6/87 28Si investigation of the total charge changing cross sections. These results also show an energy dependence. With the University of Siegen group, we have analyzed the test data from a new drift chamber system and used the system to provide trajectory measurements for the 28Si run in B40. The test data demonstrated position resolution of better than 100μm in some operating modes, and a study of the resolution dependence on timing mode, discriminator setting and wire voltage has been prepared for publication. The 28Si run provided 30-50% of the data we had hoped to obtain. There were significant beam and beamline tuning problems at our rigidity. Nevertheless, a relatively complete dataset for 245 MeV/n 28Si was obtained, processed and calibrations are in progress. In addition, we have participated in a HISS run at 2.1 GeV/n obtaining data on the fragmentation of 4He and 20Ne. All of the datasets, both B40 and HISS, are being analyzed and significant progress has been achieved. 20 figs

    The present project involves the second phase of research on a new concept in coal-water fuel (CWF) atomization that is applicable to burning in small combustors. It is intended to address the most important problem associated with CWF combustion; i.e., production of small spray droplets in an efficient manner by an atomization device. Phase 1 of this work was successfully completed with the development of an opposed-jet atomizer that met the goals of the first contract. Performance as a function of operating conditions was measured, and the technical feasibility of the device established in the Atlantic Research Atomization Test Facility employing a Malvern Particle Size Analyzer. Testing then proceeded to a combustion stage in a test furnace at a firing rate of 0.5 to 1.5 MMBtu/H.

    1990-12-31

    This project will be the first North American demonstration of the Gas Suspension Absorption (GSA) System in its application for flue gas desulfurization. The purpose of this project is to demonstrate the high sulfur dioxide (SO{sub 2}) removal efficiency as well as the cost effectiveness of the GSA system. GSA is a novel concept for flue gas desulfurization developed by F.L. Smidth miljo (FLS miljo). The GSA system is distinguished in the European market by its low capital cost, high SO{sub 2} removal efficiency and low operating cost. The specific technical objectives of the GSA demonstration project are to: effectively demonstrate SO{sub 2} removal in excess of 90% using high sulfur US coal. Optimize recycle and design parameters to increase efficiencies of lime reagent utilization and SO{sub 2} removal. Compare removal efficiency and cost with existing Spray Dryer/Electrostatic Precipitator technology.

    The improvement and technical development of promising methods for desulfurizing and recovering fine coal underway includes froth flotation, selective oil agglomeration, pelletization, and a chemical desulfurization process which involves leaching fine coal with a hot dilute solution of sodium carbonate containing dissolved oxygen under pressure. A preliminary assessment of the state of the art and review of the technical literature has been made. Equipment and apparatus have been assembled for small-scale laboratory experiments in froth flotation, oil agglomeration and chemical desulfurization. Preliminary froth flotation tests have been carried out on an Iowa coal to establish baseline data. Quite unexpectedly these tests indicated that aluminum nitrate may be an activator for coal because it served to increase the recovery of coal. Several potential flotation depressants for pyrite have been screened by measurement at the zeta potential and floatability of pyrite or coal in aqueous suspensions containing the potential depressants. The following reagents show some promise as pyrite depressants: ferric chloride, sodium cyanide, ammonium thiocyanate, and the disodium salt of ethylenediaminetetraacetic acid. Preliminary plans have been prepared for a continuous flow bench-scale system to demonstrate the process. This system will include equipment for grinding and pretreating the coal as well as equipment for demonstrating froth flotation, selective oil agglomeration and pelletization. An investigation of coal microstructure as it relates to coal beneficiation methods has also been initiated. The distribution of various forms of pyrite by size and crystal structure has been determined for two cannel samples of coal through application of scanning electron microscope techniques.

    Alcohol is degraded primarily by alcohol dehydrogenase (ADH) wherein genetic variation that affects the rate of alcohol degradation is found in ADH1B and ADH1C. It is biologically plausible that these variations may be associated with alcohol drinking habits and alcoholism. By genotyping 9080 white...... men and women from the general population, we found that men and women with ADH1B slow vs fast alcohol degradation drank more alcohol and had a higher risk of everyday drinking, heavy drinking, excessive drinking and of alcoholism. For example, the weekly alcohol intake was 9.8 drinks (95% confidence......, individuals with ADH1C slow vs fast alcohol degradation had a higher risk of heavy and excessive drinking. For example, the OR for heavy drinking was 1.4 (95% CI: 1.1-1.8) among men with the ADH1C.1/2 genotype and 1.4 (95% CI: 1.0-1.9) among men with the ADH1B.2/2 genotype, compared with men with the ADH1C.1...

  2. Translating Alcohol Research

    Alcohol use disorder (AUD) and its sequelae impose a major burden on the public health of the United States, and adequate long-term control of this disorder has not been achieved. Molecular and behavioral basic science research findings are providing the groundwork for understanding the mechanisms underlying AUD and have identified multiple candidate targets for ongoing clinical trials. However, the translation of basic research or clinical findings into improved therapeutic approaches for AUD must become more efficient. Translational research is a multistage process of streamlining the movement of basic biomedical research findings into clinical research and then to the clinical target populations. This process demands efficient bidirectional communication across basic, applied, and clinical science as well as with clinical practitioners. Ongoing work suggests rapid progress is being made with an evolving translational framework within the alcohol research field. This is helped by multiple interdisciplinary collaborative research structures that have been developed to advance translational work on AUD. Moreover, the integration of systems biology approaches with collaborative clinical studies may yield novel insights for future translational success. Finally, appreciation of genetic variation in pharmacological or behavioral treatment responses and optimal communication from bench to bedside and back may strengthen the success of translational research applications to AUD.

  4. Turning to alcohol?

    International Nuclear Information System (INIS)

    Brazil is examining whether turning to alcohol could solve its problems. The fuel alcohol producers are lobbying hard for the government to increase the use of alcohol to fuel the country's cars. Not only does using alcohol reduce CO2, runs the argument, but the Kyoto agreement might just attract international financing for the project. (author)

    This is a progress report on a four-year research program entitled `Development of a Thermionic Magnicon Amplifier at 11.4 GHz`, which is under way in the Plasma Physics Division of the Naval Research Laboratory (NRL) under Interagency Agreement DE-AI02-94ER40681. This report covers the period 16 May 1994 through 31 December 1995. The magnicon is an advanced microwave tube with potential application to future high gradient linear accelerators such as TeV colliders. Under this program, NRL plans to build and test a thermionic magnicon amplifier tube powered by a 500 kV, 200 A, 10 Hz modulator with a 1 {mu}sec pulse. However, the experiments that were carried out during the period covered by this report were driven by a single-shot Marx generator, and the electron beam was produced from a graphite plasma cathode.

    Although the period covered by this progress report began on December 20, 1994, which was the date that DOE approved the Interagency Agreement, the agreement was not approved by USDA until January 9, 1995 and the first scientists working on the project were not hired until February 1, 1995. The first goal of the research supported by the Interagency Agreement is to use hydroponic techniques to identify plant species and genotypes with potential for heavy metal hyperaccumulation for planting on a test site at Silverbow Creek and for radionuclide ({sup 90}Sr and {sup 137}Cs) accumulation on a test site at INEL, Idaho, later this year. The second goal of this research is to identify soil amendment procedures that will enhance the bioavailability of heavy metals and radionuclides in the soil without increasing the movement of the contaminants of concern (COC`s) into the groundwater. Our initial research covered in this report focuses on the first goal.

    The primary goal of this project is the engineering development of two advanced physical fine coal cleaning processes, column flotation and selective agglomeration, for premium fuel applications. The project scope includes laboratory research and bench-scale testing on six coals to optimize these processes, followed by design, and construction of a 2-t/hr process development unit (PDU). The PDU will then be operated to generate 200 tons of each of three project coals, by each process. During Quarter 11 (April--June, 1995), work continued on the Subtask 3.2 in-plant testing of the Microcel{trademark} flotation column at the Lady Dunn Preparation Plant with the installation and calibration of a refurbished 30-inch diameter column. The evaluation of toxic trace element data for column flotation samples continued, with preliminary analysis indicating that reasonably good mass balances were achieved for most elements, and that significant reductions in the concentration of many elements were observed from raw coal, to flotation feed, to flotation product samples. Significant progress was made on Subtask 6.5 selective agglomeration bench-scale testing. Data from this work indicates that project ash specifications can be met for all coals evaluated, and that the bulk of the bridging liquid (heptane) can be removed from the product for recycle to the process. The detailed design of the 2 t/hr selective agglomeration module progressed this quarter with the completion of several revisions of both the process flow, and the process piping and instrument diagrams. Procurement of coal for PDU operation began with the purchase of 800 tons of Taggart coal. Construction of the 2 t/hr PDU continued through this reporting quarter and is currently approximately 60% complete.

    BACKGROUND AND OBJECTIVE Internet alcohol marketing is not well studied despite its prevalence and potential accessibility and attractiveness to youth. The objective was to examine longitudinal associations between self-reported engagement with Internet alcohol marketing and alcohol use transitions in youth. METHODS A US sample of 2012 youths aged 15 to 20 was surveyed in 2011. An Internet alcohol marketing receptivity score was developed, based on number of positive responses to seeing alcohol advertising on the Internet, visiting alcohol brand Web sites, being an online alcohol brand fan, and cued recall of alcohol brand home page images. We assessed the association between baseline marketing receptivity and both ever drinking and binge drinking (≥6 drinks per occasion) at 1-year follow-up with multiple logistic regression, controlling for baseline drinking status, Internet use, sociodemographics, personality characteristics, and peer or parent drinking. RESULTS At baseline, ever-drinking and binge-drinking prevalence was 55% and 27%, respectively. Many (59%) reported seeing Internet alcohol advertising, but few reported going to an alcohol Web site (6%) or being an online fan (3%). Higher Internet use, sensation seeking, having family or peers who drank, and past alcohol use were associated with Internet alcohol marketing receptivity, and a score of 1 or 2 was independently associated with greater adjusted odds of initiating binge drinking (odds ratio 1.77; 95% confidence interval, 1.13–2.78 and odds ratio 2.15; 95% confidence interval, 1.06–4.37 respectively) but not with initiation of ever drinking. CONCLUSIONS Although high levels of engagement with Internet alcohol marketing were uncommon, most underage youths reported seeing it, and we found a prospective association between receptivity to this type of alcohol marketing and future problem drinking, making additional research and ongoing surveillance important.

  10. Implementing waste minimization at an active plutonium processing facility: Successes and progress at technical area (TA) -55 of the Los Alamos National Laboratory

    International Nuclear Information System (INIS)

    The Los Alamos National Laboratory has ongoing national security missions that necessitate increased plutonium processing. The bulk of this activity occurs at Technical Area -55 (TA-55), the nations only operable plutonium facility. TA-55 has developed and demonstrated a number of technologies that significantly minimize waste generation in plutonium processing (supercritical CO2, Mg(OH)2 precipitation, supercritical H2O oxidation, WAND), disposition of excess fissile materials (hydride-dehydride, electrolytic decontamination), disposition of historical waste inventories (salt distillation), and Decontamination ampersand Decommissioning (D ampersand D) of closed nuclear facilities (electrolytic decontamination). Furthermore, TA-55 is in the process of developing additional waste minimization technologies (molten salt oxidation, nitric acid recycle, americium extraction) that will significantly reduce ongoing waste generation rates and allow volume reduction of existing waste streams. Cost savings from reduction in waste volumes to be managed and disposed far exceed development and deployment costs in every case. Waste minimization is also important because it reduces occupational exposure to ionizing radiation, risks of transportation accidents, and transfer of burdens from current nuclear operations to future generations

    This program is directed at performing experimental and analytical investigations, deriving system designs, and estimating costs to ascertain the feasibility of using aluminosilicate-based getters for controlling alkali in pressurized gasification systems. Its overall objective is to develop a plan for evaluating a scaled-up version of the gettering process as a unit operation or as an integral part of a particulate removal device. This report describes work completed on the four technical program tasks: Thermodynamic projections; Getter Selection and Qualification; System Performance Projections; and Program Definition for Concept Scale-up during the 27-month contract performance period. Work completed on the thermodynamic projections includes a data base update, development of alkali phase diagrams, and system performance projections. Getter selection and qualification efforts involved over 70 kinetic studies in which a leading candidate getter - emathlite - was selected and characterized. System performance projections identified a packed-bed configuration containing relatively large getter pellets as the preferred contacting device for a full-scale unit. For emathlite, we concluded that full-scale unit bed heights of 2 m or less would be required if we assume annual replacement on the basis of bed saturation capacity. Concept scale-up work involved defining the hardware and test program requirements for further development of the emathlite packed-bed system. 56 references, 80 figures, 74 tables.

    Full Text Available Abstract Background Skills labs provide a sheltered learning environment. As close supervision and individual feedback were proven to be important in ensuring effective skills training, we implemented a cross-year peer tutor system in our skills lab of internal medicine that allowed intense training sessions with small learning groups (3–4 students taught by one student tutor. Methods The expectations, experiences and criticisms of peer tutors regarding the tutor system for undergraduate skills lab training were investigated in the context of a focus group. In addition, tutees' acceptance of this learning model and of their student tutors was evaluated by means of a pre/post web-based survey. Results 14 voluntary senior students were intensely prepared by consultants for their peer tutor activity. 127 students participated in the project, 66.9% of which responded to the web-based survey (23 topics with help of 6-point Likert scale + free comments. Acceptance was very high (5.69 ± 0.07, mean ± SEM, and self-confidence ratings increased significantly after the intervention for each of the trained skills (average 1.96 ± 0.08, all p Conclusion This study demonstrates that peer teaching in undergraduate technical clinical skills training is feasible and widely accepted among tutees, provided that the tutors receive sufficient training and supervision.

    While the harmful effects of alcohol during pregnancy are well-established, the consequences of alcohol intake during lactation have been far less examined. We reviewed available data on the prevalence of alcohol intake during lactation, the influence of alcohol on breastfeeding......, the pharmacokinetics of alcohol in lactating women and nursing infants and the effects of alcohol intake on nursing infants. A systematic search was performed in PubMed from origin to May 2013, and 41 publications were included in the review. Approximately half of all lactating women in Western countries consume...... alcohol while breastfeeding. Alcohol intake inhibits the milk ejection reflex, causing a temporary decrease in milk yield. The alcohol concentrations in breast milk closely resemble those in maternal blood. The amount of alcohol presented to nursing infants through breast milk is approximately 5...

    Alcohol dependence and abuse is one of the most costly health problems in the world from both a social and an economic point of view. It is a widespread problem, focusing attention not only psychiatrists but also doctors of other specialties. Patterns of drinking appear to be changing throughout the world, with more women and young people drinking heavily. Even risky drinking is a potential health risk, while chronic alcohol abuse contribute to the serious physical and mental complications. Alcohol used disorders associated with alcohol-induced brain damage include: withdrawal state, delirium tremens, alcoholic hallucinosis, alcoholic paranoia, Korsakoffs psychosis, alcoholic dementia, alcoholic depression. On the other hand, mental disorders as panic disorder, social anxiety disorder, agoraphobia, depression, bipolar disorder, schizophrenia, personality disorder most frequently comorbid with alcohol abuse or they trigger alcohol.

    Acute alcoholic hepatitis (AAH) is characterised by deep jaundice in patients with a history of heavy alcohol use, which can progress to liver failure. A clinical diagnosis of AAH can be challenging to make in patients without a clear alcohol history or in the presence of risk factors for other causes of acute liver failure. Other causes of acute on chronic liver failure such as sepsis or variceal haemorrhage should be considered. Liver biopsy remains the only reliable method to make an accur...

  18. Alcohol-induced histone acetylation reveals a gene network involved in alcohol tolerance.

    Directory of Open Access Journals (Sweden)

    Alfredo Ghezzi

    Full Text Available Sustained or repeated exposure to sedating drugs, such as alcohol, triggers homeostatic adaptations in the brain that lead to the development of drug tolerance and dependence. These adaptations involve long-term changes in the transcription of drug-responsive genes as well as an epigenetic restructuring of chromosomal regions that is thought to signal and maintain the altered transcriptional state. Alcohol-induced epigenetic changes have been shown to be important in the long-term adaptation that leads to alcohol tolerance and dependence endophenotypes. A major constraint impeding progress is that alcohol produces a surfeit of changes in gene expression, most of which may not make any meaningful contribution to the ethanol response under study. Here we used a novel genomic epigenetic approach to find genes relevant for functional alcohol tolerance by exploiting the commonalities of two chemically distinct alcohols. In Drosophila melanogaster, ethanol and benzyl alcohol induce mutual cross-tolerance, indicating that they share a common mechanism for producing tolerance. We surveyed the genome-wide changes in histone acetylation that occur in response to these drugs. Each drug induces modifications in a large number of genes. The genes that respond similarly to either treatment, however, represent a subgroup enriched for genes important for the common tolerance response. Genes were functionally tested for behavioral tolerance to the sedative effects of ethanol and benzyl alcohol using mutant and inducible RNAi stocks. We identified a network of genes that are essential for the development of tolerance to sedation by alcohol.

All of these studies have contributed significantly to expanding our understanding of the electronic structure and bonding of organic molecules and the ways this electronic structure is altered by interaction with metals. Further developments in the instrumentation and methods of gas phase and surface photoelectron spectroscopy are underway. Most notable is the progress on the new gas phase photoelectron spectrometer that combines improved capabilities for He I/He II UPS, XPS, and Auger investigations of organometallic molecules.

    Methods and techniques for transferring germplasm from wild to cultivated species are being developed. The transferred germplasm is being shown to be valuable in plant breeding and in cultivar development. In the primary gene pool of the grassy Pennisetum glaucum subspecies monodii germplasm, some cytoplasms are being identified that appear to have significant effects on forage yields and morphological characteristics. One cytoplasm, A{sub 4}, is very stable for male sterility and fertility is not easily restored by other lines. It should be a valuable cytoplasm for producing commercial forage hybrids. Disease resistance and yield genes transferred from monodii to cultivated pearl millet lines are having a major impact on increasing production of animals grazing disease resistant Tifleaf 2 pearl millet. Genes controlling resistance to many of the world-wide diseases on pearl millet are being identified in the monodii germplasm. Valuable germplasm has been transferred from the secondary gene pool P. purpuroum) which is used as the pollinator of the first pearl millet grain hybrid in the US Production of 7-chromosome gametes in 42-chromosome interspecific hybrids appears to be genotype specific and makes possible transfer of germplasm from the secondary gene pool to cultivated diploid pearl millet. Significant progress has been made in transferring genes controlling apomixis from P. squamulatum (tertiary gene pool) to cultivated pearl millet. Highly apomictic BC{sub 4} plants have been recovered, one of which sets five times as much seed as the best BC{sub 3} plant.

    Iowa Thin Film Technologies, Inc.`s (ITF) goal is to develop the most cost effective PV manufacturing process possible. To this end the authors have chosen a roll based manufacturing process with continuous deposition and monolithic integration. Work under this program is designed to meet this goal by improving manufacturing throughput and performance of the manufactured devices. Significant progress was made during Phase 2 of this program on a number of fronts. A new single pass tandem deposition machine was brought on line which allows greatly increased and improved throughput for rolls of tandem material. The TCO deposition process was improved resulting in an increase in throughput by 20%. A new alignment method was implemented on the printing process which improves throughput six fold while improving alignment from 100 {micro}m to 10 {micro}m. A roll based lamination procedure was developed and implemented on selected products which improves throughput from 20 sq. ft./hr. to 240 sq. ft./hr. A wide range of lower cost encapsulants were evaluated. A promising material was selected initially to be introduced in 5 year lifetime type products. The sum of these improvements bring the overall cost reduction resulting from this program to 49%.

  2. Research and development of methods/utilities and rules for managing cooperation for performance improvement in government offices. First technical progress report, September 1, 1991--August 31, 1992

    1992-03-01

    On September 1, 1991, Defense Programs (DP) within the US Department of Energy entered into a research grant with Management Systems Laboratories (MSL) of Virginia Polytechnic Institute and State University (Virginia Tech), to study Tools, Methods, and Rules for Managing Cooperation for Performance Improvement. Continuous performance improvement is a gradual, systematic process. The idea is to do a little better each day by knowing where you are, where you want to be, what you have to do to get there, whether or not you have done it, and how to resolve problems doing it. And, although many management decisions are made along direct lines of authority, much of the work of an organization can be achieved only through cooperation (people sharing information and coordinating effort). Therefore, continuous performance improvement requires working cooperatively to do a little better each day. We are researching the most effective configuration of tools working through what we believe is a closed set of nine methods. These methods are: setting expectations, charting, defining indicators and standards, collecting and logging data, converting data to information, organizing and presenting information, reviewing status and progress, self-management, and appraising. We believe that these methods form a closed set because they reflect the management activities of formulation (planning),execution (doing), and verification (evaluating). If these activities are carried out effectively through the methods, the manager can achieve visibility and control.

    Natural products have a long history of use in traditional medicines and their activities against different diseases have been the focus of many basic and clinical researches in past few decades. The essential oils, volatile liquid containing aroma compound from plants, are known as active ingredients in the herbal medicine. Perillyl alcohol (POH) is usually available through dietary sources and is being explored for its cancer chemoprevention, tumor growth suppression, and regression. Citrus peels are the waste product of juice manufacturing industries and have been considered as a critical problem for environmental green ecology policies for years. One of the most well-known approaches to overcome this problem is transformation of these monoterpene by the use of specific strains of bacteria or yeasts. Limonene (1-methyl-4-isopropyl-cyclohexene) is a monoterpene, as other monoterpenes consists of two isoprene units, that comprises more than 90% of citrus essential oil and it exists in many fruits and vegetables. Although, the anticancer activity of d-limonene has identified nearly two decades ago, it has recently attracted much more attention in translational medicine. In this chapter, we will overview the anticancer effects of POH and d-limonene. Later, we will address the pharmacokinetics of these compounds, highlight the signaling pathways which are targeted by these proteins, review the clinical trials which have been done for these compounds in different cancer models, and finally discuss the future directions of the research in this field that might be more applicable in future cancer therapy strategies.

  8. Effects of low-temperature catalytic pretreatments on coal structure and reactivity in liquefaction. Technical progress report, August 1992--November 1992

    During this quarterly period progress has been made in the following three subjects related to the effects of low-temperature thermal and catalytic pretreatments on coal structure and reactivity in liquefaction. First, the liquefaction behavior of three bituminous coals with a carbon content ranging from 77% to 85% was evaluated spectroscopically by {sup 13}C NMR and pyrolysis/gas chromatography/mass spectrometry to delineate the structural changes that occur in the coal during liquefaction. Complementary data includes ultimate and proximate analysis, along with optical microscopy for maceral determinations. Even though these are all bituminous coals they exhibit quite different physical and chemical characteristics. The coals vary in rank, ranging from HvC b to HvA b, in petrographic composition, different maceral percentages, and in chemical nature, percent of carbon and of volatiles. It is these variations that govern the products, their distribution, and conversion percentages. Some of the products formed can be traced to a specific maceral group. Second, pyrolysis-GC-MS and FTIR techniques were used to characterize Wyodak coal before and after drying in vacuum and in air and the residues from its thermal and catalytic liquefactions. The analysis of the air-dried coal shows a decrease in the phenolic type structures in the coal network and increase in the carbonyl structures as the oxidative drying proceeds. An enhanced decrease in the carbonyl structure is observed in the liquefaction residues from the raw coal as compared to that of the vacuum dried coal. The analyses of the liquefaction residues of the air-dried coal show an increase in the ether linkages which may have a negative impact on liquefaction. The extent of the solvent adduction also increases during liquefaction with the extent of oxidation of the coal. Finally, the effects of reaction conditions were investigated on conversion of low-rank coals using a Texas subbituminous coal.

    In this quarter, progress has been made in the following two aspects: (1) spectroscopic and chemical reaction studies on the effects of drying and mild oxidation of a Wyodak subbituminous coal on its structure and pretreatment/liquefaction at 350{degrees}C; and (2) effects of dispersed catalyst and solvent on conversion and structural changes of a North Dakota lignite. Drying and oxidation of Wyodak subbituminous coal at 100-150{degrees}C have been shown to have significant effects on its structure and on its catalytic and non-catalytic low-severity liquefaction at 350{degrees}C for 30 min under 6.9 MPa H{sub 2}. Spectroscopic analyses using solid-state {sup 13}C NMR, Pyrolysis-GC-MS, and FT-IR revealed that oxidative drying at 100-150{degrees}C causes the transformation of phenolics and catechol into other related structures (presumably via condensation) and high-severity air drying at 150{degrees}C for 20 h leads to disappearance of catechol-like structure. Increasing air drying time or temperature increases oxidation to form more oxygen functional groups at the expense of aliphatic carbons. Such a clearly negative impact of severe oxidation is considered to arise from significantly increased oxygen functionality which enhances the cross-link formation in the early stage of coal liquefaction. Physical, chemical, and surface physicochemical aspects of drying and oxidation and the role of water are also discussed. A North Dakota lignite (DECS-1) coal was studied for its behaviors in non-catalytic and catalytic liquefaction. Reactions were carried out at temperatures between 250 and 450{degrees}C. Regardless the reaction solvents and the catalyst being used, the optimum temperature was found to be 400{degrees}C. The donor solvent has a significant effect over the conversion especially at temperatures higher than 350{degrees}C.

  10. Adaptive harvest management for the Svalbard population of pink‐footed geese: 2016 progress summary: Technical Report from DCE – Danish Centre for Environment and Energy, No. 86

    This document describes progress to date on the development of an adaptive harvest management strategy for maintaining the Svalbard population of pink‐footed geese (Anser brachyrhynchus) near their agreed target level (60,000) by providing for sustainable harvests in Norway and Denmark. This report provides an assessment of the most recent monitoring information (1991-2015) and its implications for the harvest management strategy. By combining varying hypotheses about survival and reproduction, a suite of nine models have been developed that represent a wide range of possibilities concerning the extent to which demographic rates are density dependent or independent. These results suggest that the pink‐footed goose population may have recently experienced a release from density‐dependent mechanisms, corresponding to the period of most rapid growth in population size. Beginning with the 2016 hunting season, harvest quotas will be prescribed on an annual basis rather than every three years because of the potential to better meet population management objectives. Based on updated model weights, the recent observations of population size (74,800), the proportion of the population comprised of one-year-old birds (0.138), and temperature days in Svalbard (20), the optimal harvest quota for the 2016 hunting season is 25,000. The large increase in quota compared to that during first three years of AHM reflects stakeholders’ desire to reduce population size to the goal of 60,000, recognizing that population size remains relatively high and above-average production is expected in 2016 due to a warm spring.

    Progress has been made towards the quantitative determination of anisotropic yield criteria for several foliated and lineated rocks, towards developing models for their mechanical properties based upon interactions between deformation mechanisms and preexisting fabric elements, and towards the characterization of fabrics resulting from diapiric emplacement of magma bodies within shallow portion of the earth's crust. The suite of extension and compression experiments on Four-mile gneiss is nearly complete. Samples cored along six different orientations have been tested at temperatures ranging from 25/degree/ to 800/degree/C and confining pressures of 0 to 400 MPa at a strain rate of 10/sup /minus/5//s, and we are currently investigating the influence of strain rate on yield strength over the range 10/sup /minus/4/less than or equal to/dot /var epsilon//less than or equal to10/sup /minus/6//s. We have examined deformation microstructures of deformed gneiss samples and identified those processes at the grain scale which are associated with its inelastic response. The orthorhombic anisotropy of fracture strength exhibited by the gneiss may be explained by a simple model involving localized slip within micas and microcracking within the stronger, surrounding framework silicates. Micas appear to interact in much the same way as do Mode II shear cracks, and their density, distribution, and preferred orientation affect the nucleation of microcracks which ultimately lead to failure. Ten material parameters of a generalized anisotropic yield function for Four-mile gneiss at room temperature have been determined using nonlinear fitting methods applied to the completed room temperature data. 45 refs.

    The Plasma Science Committee (PLSC) of the National Research Council (NRC) is charged with monitoring the health of the field of plasma science in the United States. Accordingly, the Committee identifies and examines both broad and specific issues affecting the field. Regular meetings, teleconferences, briefings from agencies and the scientific community, the formation of study panels to prepare reports, and special symposia are among the mechanisms used by the PLSC to meet its charge. This progress report presents a review of PLSC activities from June 1, 1993 to May 31, 1994. The details of prior activities are discussed in earlier reports. This report also includes the status of activities associated with the PLSC study on opportunities in plasma science and technology. During the above period, the PLSC continued to track and participate in, when requested, discussions on the health of the field. Much of the perspective of the PLSC has been presented in its report Research Briefing on Contemporary Problems in Plasma Science. That report not only has served as the basis for briefings to representatives of the federal government and the community-at-large, but also served as the starting point for the Panel on Opportunities in Plasma Science and Technology (OPST) as it began an assessment of the field. The PLSC also continued its follow-up briefings and discussions on the results of the report Plasma Processing of Materials: Scientific and Technological Opportunities (PPPM). As a result of these activities, the Committee is now working with the NRC Committee on Atomic, Molecular, and Optical Sciences (CAMOS) to organize a symposium on database needs in plasma processing of materials.

    The primary goal of this project is the engineering development of two advanced physical fine coal cleaning processes, column flotation and selective agglomeration, for premium fuel applications. The project scope includes laboratory research and bench-scale testing on six coals to optimize these processes, followed by design, and construction of a 2-t/hr process development unit (PDU). The PDU will then be operated to generate 200 ton lots of each of three project coals, by each process. The project began in October, 1992 and is scheduled for completion by March, 1997. During Quarter 9 (October--December, 1995), parametric and optimization testing was completed for the Taggart, Sunnyside, and Indiana VII coal using a 12-inch Microcel{trademark} flotation column. The detailed design of the 2-t/hr PDU grinding, flotation, and dewatering circuits neared completion with the specification of the major pieces of capital equipment to be purchased for these areas. Selective agglomeration test work investigated the properties of various industrial grades of heptane for use during bench- and PDU-scale testing. It was decided to use a hydrotreated grade of commercial heptane due to its low cost and low concentration of aromatic compounds. The final Subtask 6.4 CWF Formulation Studies Test Plan was issued. A draft version of the Subtask 6.5 Preliminary Design and Test Plan Report was also issued, discussing the progress made in the design of the bench-scale selective agglomeration unit. PDU construction work moved forward through the issuing of 26 request for quotations and 21 award packages for capital equipment.

    promoter. The kinetic behavior of these materials, specifically the effects of H2, CO, and CO2 on the rates and selectivities of Fischer-Tropsch synthesis reactions has led to a new proposal for the nature of rate-determining steps on Fe and Co Fischer-Tropsch catalysts, and more specifically to the roles of hydrogen-assisted and alkali-assisted dissociation of CO in determining rates and CO2 selectivities. Finally, we have started an exploratory study of the use of colloidal precipitation methods for the synthesis of small Fe and Co clusters using recently developed methods. During this period, we have had to restrict manpower assigned to this project because some irregularities in reporting and communications have led to the interruption of funding during this period. This has led to less than optimal productivity and to significant disruptions of the technical work. These issues have also led to significant underspending of project funds during this reporting period and to our consequent request for a no-cost extension of one year, which we understand has been granted

    Full Text Available Chronic alcohol abuse causes liver disease that progresses from simple steatosis through stages of steatohepatitis, fibrosis, cirrhosis, and eventually hepatic failure. In addition, chronic alcoholic liver disease (ALD, with or without cirrhosis, increases risk for hepatocellular carcinoma (HCC. Acetaldehyde, a major toxic metabolite, is one of the principal culprits mediating fibrogenic and mutagenic effects of alcohol in the liver. Mechanistically, acetaldehyde promotes adduct formation, leading to functional impairments of key proteins, including enzymes, as well as DNA damage, which promotes mutagenesis. Why certain individuals who heavily abuse alcohol, develop HCC (7.2–15% versus cirrhosis (15–20% is not known, but genetics and co-existing viral infection are considered pathogenic factors. Moreover, adverse effects of acetaldehyde on the cardiovascular and hematologic systems leading to ischemia, heart failure, and coagulation disorders, can exacerbate hepatic injury and increase risk for liver failure. Herein, we review the role of acetaldehyde adducts in the pathogenesis of chronic ALD and HCC.

    Alcoholic liver disease (ALD) is characterized by steatosis or fat deposition in the liver and inflammation, which leads to cirrhosis and hepatocellular carcinoma. Induction of target genes without involving changes in DNA sequence seems to contribute greatly to liver injury. Chromatin modifications including alterations in histones and DNA, as well as post-transcriptional changes collectively referred to as epigenetic effects are altered by alcohol. Recent studies have pointed to a significant role for epigenetic mechanisms at the nucleosomal level influencing gene expression and disease outcome in ALD. Specifically, epigenetic alterations by alcohol include histone modifications such as changes in acetylation and phosphorylation, hypomethylation of DNA, and alterations in miRNAs. These modifications can be induced by alcohol-induced oxidative stress that results in altered recruitment of transcriptional machinery and abnormal gene expression. Delineating these mechanisms in initiation and progression of ALD is becoming a major area of interest. This review summarizes key epigenetic mechanisms that are dysregulated by alcohol in the liver. Alterations by alcohol in histone and DNA modifications, enzymes related to histone acetylation such as histone acetyltransferases, histone deacetylases and sirtuins, and methylation enzymes such as DNA methyltransferases are discussed. Chromatin modifications and miRNA alterations that result in immune cell dysfunction contributing to inflammatory cytokine production in ALD is reviewed. Finally, the role of alcohol-mediated oxidative stress in epigenetic regulation in ALD is described. A better understanding of these mechanisms is crucial for designing novel epigenetic based therapies to ameliorate ALD.

    Fetal alcohol syndrome is often associated with severe physical and neuropsychiatric maldevelopment. On the other hand, some offspring of women who drank during pregnancy appear to be affected in minimal ways and function relatively well within society. We questioned whether this effect of prenatal alcohol in the adult is generally minimal. To bear on this, we determined whether we could distinguish alcohol-exposed from nonexposed individuals in a population of male veterans, selected because of both their accepted level of function within society (e.g., honorable discharge from the military) and their admission to an alcohol treatment unit (thus, a greater likelihood of parental alcoholism, because of its familial aggregation). Consecutively admitted alcoholics (cases; n = 77) with likely maternal alcohol ingestion during their pregnancy or the first 10 years of life were matched with alcoholics with no maternal alcohol exposure during these periods (controls; n = 161). Each subject completed questionnaires regarding personal birthweight, alcohol, drug, educational and work histories, and family (including parental) alcohol and drug histories. We measured height, weight, and head circumference; checked for facial and hand anomalies; and took a frontal facial photograph, from which measurements of features were made. Data were analyzed by univariate statistics and stepwise logistic regression. No case had bona fide fetal alcohol syndrome. With univariate statistical analyses, the cases differed from the controls in 10 variables, including duration of drinking, width of alae nasae, being hyperactive or having a short attention span, and being small at birth. By stepwise logistic regression, the variables marital status, small size at birth, duration of drinking, and the presence of a smooth philtrum were marginally (the first two) or definitely (the last two) significant predictors of case status. Analysis of only the 37 cases in whom maternal prenatal drinking was

    1993-12-31

    This quarterly report discusses the technical progress of an Innovative Clean Coal Technology (ICCT) demonstration being conducted at Georgia Power Company`s Plant Hammond Unit 4 located near Rome, Georgia. The primary goal of this project is the characterization of the low NO{sub x} combustion equipment through the collection and analysis of long-term emissions data. A target of achieving fifty percent NO{sub x} reduction using combustion modifications has been established for the project. The project provides a stepwise retrofit of an advanced overfire air (AOFA) system followed by low NO{sub x} burners (LNB). During each test phase of the project, diagnostic, performance, long-term, and verification testing will be performed. These tests are used to quantify the NO{sub x} reductions of each technology and evaluate the effects of those reductions on other combustion parameters such as particulate characteristics and boiler efficiency. During this quarter, long-term testing of the LNB + AOFA configuration continued and no parametric testing was performed. Further full-load optimization of the LNB + AOFA system began on March 30, 1993. Following completion of this optimization, comprehensive testing in this configuration will be performed including diagnostic, performance, verification, long-term, and chemical emissions testing. These tests are scheduled to start in May 1993 and continue through August 1993. Preliminary engineering and procurement are progressing on the Advanced Low NOx Digital Controls scope addition to the wall-fired project. The primary activities during this quarter include (1) refinement of the input/output lists, (2) procurement of the distributed digital control system, (3) configuration training, and (4) revision of schedule to accommodate project approval cycle and change in unit outage dates.
