3-D Experimental Fracture Analysis at High Temperature (open access)

3-D Experimental Fracture Analysis at High Temperature

T*e, which is an elastic-plastic fracture parameter based on incremental theory of plasticity, was determined numerically and experimentally. The T*e integral of a tunneling crack in 2024-T3 aluminum, three point bend specimen was obtained through a hybrid analysis of moire interferometry and 3-D elastic-plastic finite element analysis. The results were verified by the good agreement between the experimentally and numerically determined T*e on the specimen surface.

Accuracy and reliability of China's energy statistics (open access)

Accuracy and reliability of China's energy statistics

Many observers have raised doubts about the accuracy and reliability of China's energy statistics, which show an unprecedented decline in recent years, while reported economic growth has remained strong. This paper explores the internal consistency of China's energy statistics from 1990 to 2000, coverage and reporting issues, and the state of the statistical reporting system. Available information suggests that, while energy statistics were probably relatively good in the early 1990s, their quality has declined since the mid-1990s. China's energy statistics should be treated as a starting point for analysis, and explicit judgments regarding ranges of uncertainty should accompany any conclusions.

Attention Disorder Drugs: Few Incidents of Diversion or Abuse Identified By Schools (open access)

Attention Disorder Drugs: Few Incidents of Diversion or Abuse Identified By Schools

A letter report issued by the General Accounting Office with an abstract that begins "Children diagnosed with attention deficit disorders are often treated with stimulant medications, such as Ritalin or Adderall. These drugs are controlled substances under federal law because of their high potential for abuse. Many of these stimulant drugs must be taken several times a day to be effective, so children need medication during the school day. Concern has arisen that the increasing use of these medications in school might provide additional opportunities for drug abuse. No data exists on the extent to which attention disorder drugs have been diverted or abused at school, or the extent to which state laws or regulations guide local school officials in safely administering these drugs. Middle and high school principals reported little diversion or abuse of attention disorder drugs. For the first seven to nine months of school year 2000-2001, about eight percent of principals in public middle and high schools reported that attention disorder drugs had been diverted or abused at their school. Most of the principals reported that school officials administer attention disorder medications, with about two percent of the school's students on average being administered attention disorder drugs …

Cross Sections and Source Spectrum for Nagasaki Dose Reconstruction for Risk Estimation

A new broad-group cross-section library with the DABL69 energy group structure and based on ENDF/B-VI Release 3 data has been created. This new library was prepared using the standard weighting function in the VITAMIN-B6 fine-group cross-section library. The new broad-group library was prepared as a requisite for a project in which various factors in estimated doses to surviving Nagasaki factory workers are being investigated. This report documents the procedure used in creating the new library and provides specifications and limitations of the data which determine the usefulness of the library for problem-specific applications. The published neutron and photon source terms for the Nagasaki calculations have been interpolated to the energy group structure of the new library and are also presented within this report.

Dairy Industry: Estimated Economic Impacts of Dairy Compacts

A letter report issued by the General Accounting Office with an abstract that begins "U.S. dairy farmers produced 167.7 billion pounds of unprocessed, raw milk in 2000. Federal and state dairy programs influence the minimum prices paid to farmers for raw milk. These prices are based on how the raw milk is to be used. Minimum prices set for raw milk to be used for making drinking milk (fluid milk) are higher than those for milk used for manufacturing cheese, butter, and other dairy products. About 70 percent of the raw milk produced in the United States is regulated under the U.S. Department of Agriculture's (USDA) federal milk marketing order program. The 1996 farm bill established another pricing program -- the Northeast Interstate Dairy Compact (NEDC) -- which is run by a commission that sets a minimum price for raw milk sold as fluid milk in six New England states. The NEDC works in conjunction with federal and state dairy programs to establish an alternative minimum price for raw milk in the Compact states. When the monthly NEDC minimum price exceeds the federal marketing order or state minimum price, the NEDC price becomes the minimum price. Congress is now considering …

DEEPLY INELASTIC SCATTERING OFF NUCLEI AT RHIC.

In this talk, we discussed the physics case for an eA collider. We emphasized the novel physics that might be studied at small x. The interesting physics at intermediate x's has been discussed elsewhere [3]. Plans for an electron-ion collider include, as a major part of the program, the possibility of doing polarized electron-polarized proton/light ion scattering. A discussion of the combined case for high energy electron nucleus and polarized electron-polarized proton scattering will be published separately [66].

Detection and Characterization of Chemicals Present in Tank Waste - Final Report - 09/15/1998 - 09/14/2001

DOE has a strong commitment to the efficient and safe remediation of waste (high level radioactive waste, mixed waste, and hazardous waste) present in underground waste storage tanks. Safety issues arise from the presence of organic chemicals and oxidizers and concerns are raised about the flammability, explosivity, and the possible corrosion of storage tanks due to presence of nitrates and nitrites. Knowledge of the physical parameters and chemical and radioactive composition of waste is necessary for effective and safe tank remediation. New and improved characterization and monitoring of waste present in storage tanks is necessary. The overall goal of this project has been to develop and demonstrate novel multi-parameter micro-electro-mechanical system (MEMS) sensors based on Si and SiNx microcantilever (MC) structures that are robust and can be used to simultaneously detect the presence of target chemicals (analytes) in a mixture, radiation emitted from radioactive materials, an d the heat generated by the absorption of photons of specific wavelength by the target analytes. The mechanisms by which adsorption, photophysical, photothermal processes cause stress in MC surfaces are better understood. Methods of applying a wide variety of chemically selective coatings have been developed specifically for miniaturized MC surfaces, and the response characteristic …

Drug Control: State Department Provides Required Aviation Program Oversight, but Safety and Security Should Be Enhanced

A letter report issued by the General Accounting Office with an abstract that begins "The Andean region continues to cultivate, produce, and export almost all of the world's cocaine as well as an increasing amount of heroin, according to the State Department. Colombia is the source of 90 percent of the cocaine entering the United States and about two-thirds of the heroin found on the East Coast. Although coca cultivation estimates have fallen by about two-thirds in Bolivia and Peru since 1996, increases in coca cultivation in Colombia have offset much of these successes. Under State's Bureau for International Narcotics and Law Enforcement Affairs, the Office of Aviation, through a contract with DynCorp Aerospace Technology, supports foreign governments' efforts to locate and eradicate illicit drug crops in the Andean region. In recent years, DynCorp has maintained and operated aircraft to locate and eradicate drug crops in Colombia, trained pilots and mechanics for the Colombian Army Aviation Brigade, and provided logistical and training support for the aerial eradication programs of the Colombian National Police and manual eradication programs in Bolivia and Peru. The Office of Aviation met both State's overall contracting oversight requirements and more specific oversight and evaluation requirements in …

Factors influencing biological treatment of MTBE contaminated ground water (open access)

Factors influencing biological treatment of MTBE contaminated ground water

Methyl tert-butyl ether (MTBE) contamination has complicated the remediation of gasoline contaminated sites. Many sites are using biological processes for ground water treatment and would like to apply the same technology to MTBE. However, the efficiency and reliability of MTBE biological treatment is not well documented. The objective of this study was to examine the operational and environmental variables influencing MTBE biotreatment. A fluidized bed reactor was installed at a fuel transfer station and used to treat ground water contaminated with MTBE and gasoline hydrocarbons. A complete set of chemical and operational data was collected during this study and a statistical approach was used to determine what variables were influencing MTBE treatment efficiency. It was found that MTBE treatment was more sensitive to up-set than gasoline hydrocarbon treatment. Events, such as excess iron accumulation, inhibited MTBE treatment, but not hydrocarbon treatment. Multiple regression analysis identified biomass accumulation and temperature as the most important variables controlling the efficiency of MTBE treatment. The influent concentration and loading of hydrocarbons, but not MTBE, also impacted MTBE treatment efficiency. The results of this study suggest guidelines for improving MTBE treatment. Long cell retention times in the reactor are necessary for maintaining MTBE treatment. The …

HISTORY OF THE ENGINEERING PHYSICS AND MATHEMATICS DIVISION 1955-1993

A review of division progress reports noting significant events and findings of the Applied Nuclear Physics, Neutron Physics, Engineering Physics, and then Engineering Physics and Mathematics divisions from 1955 to 1993 was prepared for use in developing a history of the Oak Ridge National Laboratory in celebration of its 50th year. The research resulted in an accumulation of historic material and photographs covering 38 years of effort, and the decision was made to publish a brief history of the division. The history begins with a detailed account of the founding of the Applied Nuclear Physics Division in 1955 and continues through the name change to the Neutron Physics Division in the late 1950s. The material thereafter is presented in decades--the sixties, seventies, and eighties--and ends as we enter the nineties.

HUD Information Systems: Immature Software Acquisition Capability Increases Project Risks (open access)

HUD Information Systems: Immature Software Acquisition Capability Increases Project Risks

A chapter report issued by the General Accounting Office with an abstract that begins "The Department of Housing and Urban Development (HUD) routinely acquires new information systems and enhancements to manage and support its various programs and operations. GAO has designated HUD's major program areas as high risk, in part because the department's information and financial management systems are poorly integrated, ineffective, and generally unreliable. HUD has been trying to improve its systems to better support its missions and management reforms. HUD did not fully satisfy the requirements for any of the "repeatable" key process areas GAO reviewed. Although HUD's software acquisition process has several strengths, GAO found weaknesses in all key software process areas evaluated: requirements development and management, project management, contract tracking and oversight, and software evaluation. As a result, HUD's processes for acquiring software are immature and ad hoc, sometimes chaotic, and not repeatable across projects. HUD acknowledges these weaknesses, is committed to improving its software and system acquisition processes, and will soon begin a process improvement effort."
