This report covers the history, reasoning, and current policy that surrounds tax deductions for the blind. Moreover, the report highlights the current policy (as of May 7th 2008) as one that recognizes the higher cost of living for a blind person because many blind taxpayers have low incomes. However, the report points out that because of this many of them have access to an additional deduction for being in a lower income bracket.

This report briefly summarizes the history, reasoning, and current tax deductions (as of May 7th 2008) for the elderly. The report suggests that the current tax deduction for both the elderly and the blind will result in the loss of 9 billion in tax revenue. Moreover, the report suggests that corrections could be made with alternative solutions.

Mineralized tissues, such as bone and tooth dentin, serve as structural materials in the human body and, as such, have evolved to resist fracture. In assessing their quantitative fracture resistance or toughness, it is important to distinguish between intrinsic toughening mechanisms which function ahead of the crack tip, such as plasticity in metals, and extrinsic mechanisms which function primarily behind the tip, such as crack bridging in ceramics. Bone and dentin derive their resistance to fracture principally from extrinsic toughening mechanisms which have their origins in the hierarchical microstructure of these mineralized tissues. Experimentally, quantification of these toughening mechanisms requires a crack-growth resistance approach, which can be achieved by measuring the crack-driving force, e.g., the stress intensity, as a function of crack extension ("R-curve approach"). Here this methodology is used to study of the effect of aging on the fracture properties of human cortical bone and human dentin in order to discern the microstructural origins of toughness in these materials.

This report discusses the current corporate average fuel economy (CAFE) standard of 35 miles per gallon (mpg), and the major issues on the CAFE debate. The report also offers an overview of Congressional interest in CAFE (1991-2005), and explains the CAFE and reduction of carbon dioxide emissions.

This report provides a basic explanation of how to calculate the federal estate tax liability for a taxable estate of any given size, using the schedule of graduated marginal tax rates and the applicable exclusion amount or the applicable credit amount for the year of death. The “applicable exclusion amount” is the amount of any decedent’s taxable estate that is free from tax. It is known informally as the estate tax “exemption.” The “applicable credit amount” or “unified credit” is the corresponding tax credit. It is equal to the tax that would be due on a taxable estate that is the size of the applicable exclusion amount.

This report discusses Section 1207 of the National Defense Authorization Act for Fiscal Year 2006 (P.L. 109-163), which provides authority for DOD to transfer to the State Department up to $100 million per fiscal year in defense articles, services, training or other support for reconstruction, stabilization, and security activities in foreign countries.

We present scaled demonstrations of backlighter sources, emitting Bremsstrahlung x-rays with photon energies above 75 keV, that we will use to record x-ray Compton radiographic snapshots of cold dense DT fuel in inertial confinement fusion implosions at the National Ignition Facility (NIF). In experiments performed at the Titan laser facility at Lawrence Livermore National Laboratory, we measured the source size and the Bremsstrahlung spectrum as a function of laser intensity and pulse length, from solid targets irradiated at 2e17-5e18 W/cm{sup 2} using 2-40 ps pulses. Using Au planar foils we achieved source sizes down to 5.5 {micro}m, and conversion efficiencies of about 1e-3 J/J into x-ray photons with energies in the 75-100 keV spectral range. We can now use these results to design NIF backlighter targets and shielding, and to predict Compton radiography performance as a function of the NIF implosion yield and associated background.

We report a 795-nm diode-pumpable Rb laser using a buffer gas of pure {sup 3}He. {sup 3}He gas enhances mixing of the Rb fine-structure levels. This enables efficient lasing at reduced He pressures and improved thermal management.

A letter report issued by the Government Accountability Office with an abstract that begins "Since 2001, Labor has spent nearly $900 million on three workforce employment and training grant initiatives: High Growth Job Training Initiative (High Growth), Community-Based Job Training Initiative (Community Based), and the Workforce Innovation in Regional Economic Development (WIRED). GAO was asked to examine (1) the intent of the grant initiatives and the extent to which Labor will be able to assess their effects, (2) the extent to which the process used competition, was adequately documented, and included key players, and (3) what Labor is doing to monitor individual grantee compliance with grant requirements. To answer these questions, GAO obtained from Labor a list of grants for fiscal years 2001 through 2007, and reviewed relevant laws and Labor's internal grant award procedures. GAO interviewed grantees, and state and local workforce officials in seven states where grantees were located, Labor officials, and subject matter experts."

This report describes the congressional procedure in the enrollment of legislation, which occurs in the chamber where the measure originated and is carried out by enrolling clerks under the supervision of the Clerk of the House of Representatives and Secretary of the Senate.

The project was to develop cryostat designs that could be used for muon beam cooling channels where hydrogen would circulate through refrigerators and the beam-cooling channel to simultaneously refrigerate 1) high-temperature-superconductor (HTS) magnet coils, 2) cold copper RF cavities, and 3) the hydrogen that is heated by the muon beam. In an application where a large amount of hydrogen is naturally present because it is the optimum ionization cooling material, it was reasonable to explore its use with HTS magnets and cold, but not superconducting, RF cavities. In this project we developed computer programs for simulations and analysis and conducted experimental programs to examine the parameters and technological limitations of the materials and designs of Helical Cooling Channel (HCC) components (magnet conductor, RF cavities, absorber windows, heat transport, energy absorber, and refrigerant).The project showed that although a hydrogen cryostat is not the optimum solution for muon ionization cooling channels, the studies of the cooling channel components that define the cryostat requirements led to fundamental advances. In particular, two new lines of promising development were opened up, regarding very high field HTS magnets and the HS concept, that have led to new proposals and funded projects.

A letter report issued by the Government Accountability Office with an abstract that begins "With a workforce of about 35,000, the U.S. Army Corps of Engineers (the Corps) provides engineering services for civil works and military programs in the United States and overseas. Recently, the Corps' focus has shifted to also support contingency operations, such as responding to natural disasters. To meet its mission and emerging priorities, the Corps must have effective human capital planning processes to ensure that it can maintain its workforce. In this context, GAO was asked to examine the (1) extent to which the Corps has aligned its human capital plan with its strategic plan, (2) extent to which the Corps has the information necessary to identify and meet current and future workforce needs, and (3) challenges the Corps faces in meeting its workforce needs. To address these issues, GAO reviewed agency human capital and strategic planning documents, conducted structured interviews with eight Corps divisions and a purposeful sample of 14 of its districts, and interviewed other Corps officials."

Scientific computations and collaborations increasingly rely on the network to provide high-speed data transfer, dissemination of results, access to instruments, support for computational steering, etc. The Energy Sciences Network is establishing a science data network to provide user driven bandwidth allocation. In a shared network environment, some reservations may not be granted due to the lack of available bandwidth on any single path. In many cases, the available bandwidth across multiple paths would be sufficient to grant the reservation. In this paper we investigate how to utilize the available bandwidth across multiple paths in the case of bulk data transfer.

The Kurdish-inhabited region of northern Iraq is relatively peaceful and prospering economically, but the Iraqi Kurds' political autonomy and political strength in post-Saddam Iraq is causing backlash in Arab Iraq, Turkey, and Iran. The Iraqi Kurds' ties to the United States and the U.S. drive to stabilize Iraq are increasingly less likely to help the Kurds to parry these challenges.

The aim of this work was to study radiation-induced bystander effects for early cytogenetic end points in various cell lines using the medium transfer technique after exposure to high- and low-LET radiation. Cells were exposed to 20 MeV/ nucleon nitrogen ions, 968 MeV/nucleon iron ions, or 575 MeV/nucleon iron ions followed by transfer of the conditioned medium from the irradiated cells to unirradiated test cells. The effects studied included DNA double-strand break induction, {gamma}-H2AX focus formation, induction of chromatid breaks in prematurely condensed chromosomes, and micronucleus formation using DNA repair-proficient and -deficient hamster and human cell lines (xrs6, V79, SW48, MO59K and MO59J). Cell survival was also measured in SW48 bystander cells using X rays. Although it was occasionally possible to detect an increase in chromatid break levels using nitrogen ions and to see a higher number of {gamma}-H2AX foci using nitrogen and iron ions in xrs6 bystander cells in single experiments, the results were not reproducible. After we pooled all the data, we could not verify a significant bystander effect for any of these end points. Also, we did not detect a significant bystander effect for DSB induction or micronucleus formation in these cell lines or for clonogenic survival …

This report begins by reviewing federal statutes that pertain directly or indirectly to employer provision of leave benefits for any purpose, including the Pregnancy Discrimination Act and the Family and Medical Leave Act. It then examines the incidence of different types of paid leave that U.S. employers voluntarily provide as part of an employee's total compensation (wages and benefits). The report closes with results from a federal government survey of the average direct cost to businesses of different types of leave.

Public charities, religious groups, social welfare organizations, and other nonprofit organizations which are exempt from federal income taxation are not generally prohibited from engaging in all lobbying or public policy advocacy activities merely because of their tax-exempt status. There may, however, be some lobbying limitations on certain organizations, depending. This report discusses this issue at length, including related legislation, relevant passages in the Internal Revenue Code, and other regulatory information.

This report is intended to provide a brief overview of the various potential restrictions or regulations on lobbying activities of non-profit organizations. Public charities, social welfare organizations, religious groups, and other non-profit, tax-exempt organizations are not generally prohibited from engaging in all lobbying or public policy advocacy merely because of their tax-exempt status.

The Model 9975 Shipping Package is the latest in a series (9965, 9968, etc.) of radioactive material shipping packages that have been the mainstay for shipping radioactive materials for several years. The double containment vessels are relatively simple designs using pipe and pipe cap in conjunction with the Chalfont closure to provide a leak-tight vessel. The fabrication appears simple in nature, but the history of fabrication tells us there are pitfalls in the different fabrication methods and sequences. This paper will review the problems that have arisen during fabrication and precautions that should be taken to meet specifications and tolerances. The problems and precautions can also be applied to the Models 9977 and 9978 Shipping Packages.
