This report reviews trends in mandatory spending since 1962. Congressional Budget Office (CBO) baseline projections of mandatory spending, which extend to 2018, are discussed, as well as extended baseline projections through 2082 used to explore long-term consequences of current budgetary policy. The report examines mandatory spending’s growth relative to total federal spending and to the size of the U.S. economy, and looks at how the composition of mandatory spending has changed over time.

This report examines the interrelationships of the variables regarding the debate on climate change to explore their implications for policies that address the problem. The three variables underpinning the debates and justified response to the issue are: the magnitude and rates of change of (1) population growth, (2) incomes, and (3) intensity of greenhouse gas emissions relative to economic activities.

The performance of a glass used for immobilization of high-level nuclear waste (HLW) is generally quantified by its resistance to chemical degradation, or durability. The durability of a HLW glass is dependent on its composition. If crystalline phases form within a glass during cooling, the composition of the residual glass network is altered, therefore affecting the durability of the glass. Crystallization of nepheline (NaAlSiO{sub 4}) has been shown to adversely impact the durability of HLW glasses since it removes glass forming species (in this case, Al and Si) from the glass network. The propensity for nepheline crystallization in a HLW glass increases with increasing concentrations of Al{sub 2}O{sub 3} and Na{sub 2}O in the glass. Nepheline crystallization is therefore of concern for processing of HLW at the Defense Waste Processing Facility (DWPF) since the sludge waste streams at the Savannah River Site (SRS) can contain high concentrations of Al{sub 2}O{sub 3} and Na{sub 2}O. Currently, a 'nepheline discriminator' is included as a process control constraint at the DWPF. The nepheline discriminator relates the concentrations of SiO{sub 2}, Na{sub 2}O and Al{sub 2}O{sub 3} (as weight percentages in glass) to a critical value of 0.62. The discriminator defines a boundary line …

This report talks about Calculation of C5 Stresses and Deflections in C5 Due to Thermal and Pressure Loading.

A design specification for the DES Camera focal plate is to keep the deformation of the plate to less than 30 microns under operating conditions. Figure 1 shows the assembly of the focal plate, the support bipods and support ring, and the copper braid assemblies. Several studies were done to examine the deformation of the focal plate under different thermal and structural constraints. Simple hand calculations were also performed as a check of the finite element model and results. The main goal of this analysis was to determine the deformation of the plate and to understand what thermal and structural conditions are causing the deformation.

This report discusses reasons why CFL sales have increased dramatically in the past two years, concerns that have arisen regarding their use and disposal, and some media reports that have exaggerated the potential danger associated with the mercury in CFLs.

The Social Security Administration (SSA) administers the Social Security program (Old-Age, Survivors and Disability Insurance, or OASDI) and the Supplemental Security Income (SSI) program, and provides administrative support to Medicare and several other federal programs. Total SSA spending in FY2007 was about $624 billion, about 99% of which was mandatory spending on benefit payments. This report focuses on SSA’s spending for administrative expenses, which is discretionary and amounts to about 1% of SSA’s total spending. This funding is provided in the Labor, Health and Human Services, Education, and Related Agencies appropriations bill.

This report describes the portions of the Bali Action Plan and Decision that relate to forests.

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) industry personnel security clearance program has long-standing delays and backlogs in completing clearance requests and difficulties in accurately projecting its future needs for investigations to be conducted by the Office of Personnel Management (OPM). In 2006, Congress mandated that DOD report annually on the future requirements of the program and DOD's efforts to improve it, and that GAO evaluate DOD's first report. Specifically, GAO was required to report on (1) the extent to which the report responds to the issues in the mandate, (2) the number and cost of clearance investigations and adjudications in fiscal years 2000-2006, and (3) the extent to which DOD has developed procedures to estimate future needs, plans to reduce delays and backlogs, and plans to provide funding for the program. To accomplish these objectives, GAO obtained and reviewed laws, executive orders, policies, reports, and other documents related to the security clearance process and interviewed officials from a range of government offices concerned with the clearance process."
