A letter report issued by the General Accounting Office with an abstract that begins "The Department of Defense (DOD) uses employee benefits--that is, indirect compensation above and beyond a service member's basic pay--as a tool to recruit and retain personnel. DOD has instituted a number of benefits that reflect demographic changes in the active duty force since the draft ended and the military became an all-volunteer force in 1973. Many of these benefits address one of the most significant demographic changes--an increase in service members with family obligations. A second major demographic change in the active military has been a growing proportion of female service members. DOD has responded positively to most demographic changes by incorporating a number of family-friendly benefits; however, opportunities exist to improve current benefits in this area. In comparing the types of benefits offered by the military with those offered in the private sector, GAO did not identify significant gaps in the benefits available to military personnel. GAO did not make direct comparisons between individual military and private-sector benefits but did determine that all the core benefits offered by most private-sector firms--retirement pay, health care, life insurance, and paid time off--are offered by the military."

A letter report issued by the General Accounting Office with an abstract that begins "Federal welfare legislation passed in 1996 placed a greater emphasis on helping low-income families end dependence on government benefits by promoting job preparation and work. To reach this goal, the legislation gave states greater flexibility to design programs that use federal funds to subsidize child care for low-income families. Under the Child Care and Development Fund, this flexibility includes the freedom to largely determine which low-income families are eligible to receive child care subsidies. These maximum rates consist of two parts--a state subsidy and family co-payment. States also establish maximum reimbursement rates for child care. States reported considering market rate survey and budget and policy goals in setting maximum reimbursement rates. All states reported conducting market rate surveys in the past 2 years that obtained data on providers' fees, but 10 states reported that they did not base the reimbursement rates for child care providers on their most recent market rate surveys. In the nine communities visited, GAO calculated that hypothetical families' access to child care centers and family home providers varied widely as a result of the different subsidies and family co-payments established by each …

A letter report issued by the General Accounting Office with an abstract that begins "The Board of Governors of the Federal Reserve System (Federal Reserve Board) reviewed its policies regarding the size of the Federal Reserve Banks' combined capital surplus account to determine if opportunities exist to decrease the amount held in the account. The consolidated capital surplus account is the aggregate of separate surplus accounts held at each of the 12 Reserve Banks, and the account represents cumulative retained net earnings for the Reserve Banks--that is, cumulative net earnings not paid to the Department of the Treasury. The Reserve Banks use their capital surplus accounts to act as a cushion to absorb losses. The Financial Accounting Manual for Federal Reserve Banks says that the primary purpose of the surplus account is to provide capital to supplement paid-in capital for use in the event of loss. Selected major foreign central banks maintain accounts with functions similar to the Federal Reserve System's capital surplus account. Although their accounts are not fully comparable with the Federal Reserve System capital surplus account, the Bank of England, the Bundesbank, and the European Central Bank have capital surplus or reserve accounts in addition to their …

A letter report issued by the General Accounting Office with an abstract that begins "Clinical research is critical for the development of strategies for the prevention, diagnosis, prognosis, treatment, and cure of diseases. Clinical research has been defined as patient-oriented research, epidemiologic and behavioral studies, and outcomes research and health services research. The National Institutes of Health (NIH) is the principal federal agency that funds clinical research supporting individual clinical investigators, clinical trials, general and specialized clinical research centers, and clinical research training. For many years, there have been concerns that clinical research proposals are viewed less favorably than basic research during the peer review process at NIH and that clinical research has not received its fair share of NIH funding. In November 2000, the Clinical Research Enhancement Act was enacted to address some of these concerns. NIH reports that it has increased its financial support of clinical research and that spending on clinical research has kept pace with total NIH research spending. NIH has taken some steps to improve its peer review of clinical research applications. The Center for Scientific Review recently added two new peer review study sections for the review of clinical research applications--one for clinical cardiovascular …

This paper addresses the applicability of the linear sorption model to the complex wastes of the Hanford Site.

This report describes experiments conducted to demonstrate the proof-of-principle of a method to recover NaOH from Hanford tank sludge leaching solutions. Aqueous solutions generated from leaching actual Hanford tank waste solids were used. The process involves neutralization of a lipophilic weak acid (t-octylphenol was used in these experiments) by reaction with NaOH in the aqueous phase. This results in the transfer of Na into the organic phase. Contacting with water reverses this process, reprotonating the lipophilic weak acid and transferring Na back into the aqueous phase as NaOH. The work described here confirms the potential application of solvent extraction to recover and recycle NaOH from solutions generated by leaching Hanford tank sludges. Solutions obtained by leaching sludges from tanks S-110 and T-110 were used in this work. It was demonstrated that Na+ is transferred from caustic leaching solution to the organic phase when contacted with t-octylphenol solutions. This was accompanied by a concomitant decrease in the aqueous-phase hydroxide ion concentration. Seventy to 80 % of the extracted Na was recovered by 3 to 4 sequential contacts of the organic phase with water. Cesium was co-extracted by the procedure, but Al and Cr remained in the feed stream.

Two-D numerical flow and transport experiments were performed with a meter-sized unsaturated fractured block in an attempt to validate the active fracture model (AFM) by estimating {gamma}, a positive constant relating the fraction of active fractures to the effective water saturation for the block. Two different models developed for the study include a discrete fracture network model (DFNM) and a dual continuum model (DCM). The DFNM served to synthetically generate experimental measurements for water flow rates and tracer breakthroughs, against which numerical simulation data with DCM was calibrated to estimate {gamma} values for the fracture network. Water flow rates were monitored at both top and bottom to find balanced (''pseudo-steady'') states, when a pulse of tracer injection was initiated from the top of the block. During the transient state, water flow rates in DCM did not closely predict the measurements from DFNM, which show step-wise increments with time. Based on goodness-of-fit values, the water flow rates in the range of 7.12 x 10{sup -8} and 7.12 x 10{sup -7} kg/s (0.2-2.0 % of the saturated flow rate) provide better estimates of {gamma}. The DCM may be not suitable to estimate {gamma} when the injection rates are too high or low. …

The approach of isolating high-level nuclear waste in the designated site of Yucca Mountain (Nevada) is to separate it from the environment using a series of engineering and natural barriers. The container for the waste will consist of two concentric metal cylinders. The outer cylinder is going to be fabricated of Alloy 22 (N06022). If water is present at the site, several corrosion processes may occur. These include passive or general corrosion, localized corrosion and environmentally assisted cracking. The occurrence of one (or more) mode of corrosion over another will be determined by the redox potential of the aqueous electrolyte that may enter in contact with the container. This redox potential will also control the corrosion potential (E{sub corr}) of the container. This paper summarizes the findings of an extensive laboratory testing aimed at measuring E{sub corr} of Alloy 22 in presence of a variety of electrolyte solutions. Some of these solutions are multi-ionic electrolytes that may simulate concentrated ground waters. Other environments are chemical solutions of pure salts, which are highly unlikely for an underground repository but that may establish an extreme bounding condition. Current results show that the highest measured potential for Alloy 22 was approximately +0.3 to …

Water inputs to the vadose zone from irrigation of a tree windbreak in the 200 W Area of the Hanford Site were monitored during the summer of 2002. Water flux and soil-water contents were measured within the windbreak and at two locations just east of the windbreak to assess the impact of the irrigation on the vadose zone and to assist in optimizing the irrigation applications. In May 2002, instrumentation was placed in auger holes and backfilled with local soil. Sensors were connected to a data acquisition system (DAS), and the data were telemetered to the laboratory via digital modem in late June 2002. Data files and graphics were made web accessible for instantaneous retrieval. Precipitation, drip irrigation, deep-water flux, soil-water content, and soil-water pressures have been monitored on a nearly continuous basis from the tree-line site since June 26, 2002.

Because of its low thermal conductivity, high thermal expansion and high oxygen ion conductivity yttria-stabilized zirconia (YSZ) is the material of choice for high temperature electrolyte applications. Current coating fabrication methods have their drawbacks, however. Air plasma spray (APS) is a relatively low-cost process and is suitable for large and relatively complex shapes. it is difficult to produce uniform, relatively thin coatings with this process, however, and the coatings do not exhibit the columnar microstructure that is needed for reliable, long-term performance. The electron-beam physical vapor deposition (EB-PVD) process does produce the desirable microstructure, however, the capital cost of these systems is very high and the line-of-sight nature of the process limits coating uniformity and the ability to coat large and complex shapes. The chemical vapor deposition (CVD) process also produces the desirable columnar microstructure and--under proper conditions--can produce uniform coatings over complex shapes. CVD has been used for many materials but is relatively undeveloped for oxides, in general, and for zirconia, in particular. The overall goal of this project--a joint effort of the University of Louisville and Oak Ridge National Laboratory (ORNL)--is to develop the YSZ CVD process for high temperature electrolyte applications. This report describes the modeling effort …

Our overall purpose in writing this series of articles is to provide Federal energy managers some basic informational tools to assist their decision making process relative to energy management systems design, specification, procurement, and energy savings potential. Since Federal buildings rely on energy management systems more than their commercial counterparts, it is important for energy practitioners to have a high level of knowledge and understanding of these complex systems. This is the second article in a series and will focus on building control system (BCS) networking fundamentals and an assessment of current approaches to open communications protocols. This is important because networking is a complex subject and the networks form the basic infrastructure for energy management functions and for integrating a wide variety of OEM equipment into a complete EMCIS. The first article [1] covered enabling technologies for emerging energy management systems. Future topics will concentrate on more practical aspects including applications software, product offerings, networking strategies, and case studies of actual installations. Please refer to the first article for a more complete overview of the purpose and background for this series.

Cyprus has been divided since 1974. Greek Cypriots, nearly 80% of the population, live in the southern two thirds of the island. Turkish Cypriots live in the “Turkish Republic of Northern Cyprus” (recognized only by Turkey), with about 30,000 Turkish troops providing security. U.N. peacekeeping forces maintain a buffer zone between the two. Members of Congress have urged the Administration to be more active, although they have not proposed an alternative to the U.N.-sponsored talks.
