This report discusses the mission of the North Atlantic Treaty Organization (NATO) in Afghanistan, the purpose of which is to stabilize and reconstruct Afghanistan by combating emerging threats such as terrorism and the proliferation of weapons of mass destruction. This report also discusses how the Obama Administration has made the Afghanistan conflict a policy priority, and what this stance could mean for potential future endeavors.

This report discusses issues surrounding Japan's interest in purchasing the F-22A Raptor aircraft from the United States. Although the export of the plane is now prohibited by U.S. law, Congress has recently and may again consider repealing this ban.

This report analyzes an array of bilateral issues that continue to affect relations between the United States and Syria. It includes descriptions of recent developments, issues for Congress, U.S.-Syrian relations, U.S. Sanctions, and future prospects related to the role of Congress.

Jet-cooled spectra of 1-methylvinoxy and 2-methylvinoxy are reported and analyzed with help from high-level electronic structure calculations.

This report examines some of the policy and legal issues that may accompany an increased role of state and local law officials in the enforcement of immigration law.

Over the years, the United States has been concerned about threats to Latin American and Caribbean nations from various terrorist or insurgent groups that have attempted to influence or overthrow elected governments. This report discusses these concerns and briefly takes a look at the United States' increased cooperation with the region in the wake of the 9/11 attacks.

The SIAM Conference on Geometric Design and Computing attracted 164 domestic and international researchers, from academia, industry, and government. It provided a stimulating forum in which to learn about the latest developments, to discuss exciting new research directions, and to forge stronger ties between theory and applications. Final Report

The sustained propagation of combustion fronts in porous media is a necessary condition for the success of an in situ combustion project for oil recovery. Compared to other recovery methods, in situ combustion involves the added complexity of exothermic reactions and temperature-dependent chemical kinetics. In the presence of heat losses, the possibility of ignition and extinction (quenching) exists. In this report, we address the properties of combustion fronts propagating at a constant velocity in the presence of heat losses.

Recent research has shown that certain manganese oxides have the ability to sorb aqueous metal cations much more efficiently than any of the naturally occurring iron oxides when normalized to surface area. This ability is, at least in part, related to the internal sites available in many manganese oxide structures, including those within tunnels and between sheets. Additionally, a new naturally-occurring manganese oxide structurally related to vernadite ({delta}-MnO{sub 2}), collected along the Clark Fork River in western Montana, USA, has shown the ability to sorb arsenate, an anionic complex. The potential for manganese oxides to sorb anions has made it an attractive material as a radionuclide ''getter''. According to the US Department of Energy's Total Systems Performance Assessment, technetium and iodine are two major anionic radionuclides contributing to the list of potential contaminants released from Yucca Mountain repository, Nevada, USA. These two radionuclides are extremely problematic because they are very mobile in the environment. This project involves running flow-through sorption experiments using rhenium (a surrogate for technetium) and stable iodine as sorbates and several synthetic manganese oxides, including birnessite, vernadite, cryptomelane, and possibly the new vernadite-like phase mentioned earlier, as sorbants. For all synthesis reactions, manganese (VII) salts are reduced …

Appropriations are one part of a complex federal budget process that includes budget resolutions, appropriations (regular, supplemental, and continuing) bills, rescissions, and budget reconciliation bills. This report is a guide to one of the 13 regular appropriations bills that Congress passes each year. It is designed to supplement the information provided by the House and Senate Labor, Health and Human Services, and Education Appropriations Subcommittees.

This report discusses the ongoing debate about whether or not to approve energy development in the Arctic National Wildlife Refuge (ANWR). Current law forbids energy leasing in the Refuge. This report addresses several legislative options on the issue, as well as policymakers' arguments for and against development, especially in the wake of increasing terrorism since 2000-2001.

This report examines the role of state and local law enforcement in enforcing immigration law. The discussion is limited to the role of state and local law enforcement in the investigation, arrest, and detention of all immigration violators. The report does not discuss the prosecution, adjudication, or removal of aliens who violate the law. The report opens with a brief discussion of the types of immigration interior enforcement activities that the former Immigration and Naturalization Service (INS) pursued and the current immigration activities that are now the focus of the Department of Homeland Security (DHS). A discussion of the legal authority that permits state and local law enforcement to enforce immigration law under certain circumstances follows. Current administrative efforts to involve state and local law enforcement in enforcing immigration law as well as selected issues are discussed. The report concludes with a discussion of the pros and cons of such a policy and an analysis of policy options for Congress.

In October 2002, the United States confronted North Korea about its alleged clandestine uranium enrichment program. Soon after, the Agreed Framework collapsed, North Korea expelled international inspectors, and withdrew from the Nuclear Nonproliferation Treaty (NPT). U.S. intelligence officials claimed Pakistan was a key supplier of uranium enrichment technology to North Korea, and some media reports suggested that Pakistan had exchanged centrifuge enrichment technology for North Korean help in developing longer range missiles.

This report discusses each of the provisions in Title XI of P.L. 108-136 and plans to implement the law. Title XI of the National Defense Authorization Act for FY2004, P.L. 108-136, includes provisions on a National Security Personnel System (NSPS) for the Department of Defense (DOD) and provisions on personnel management that are applicable government-wide. The law was enacted on November 24, 2003.

Some policymakers, believing that disparities in broadband access across American society could have adverse economic and social consequences on those left behind, assert that the federal government should play a more active role to avoid a “digital divide” in broadband access. One approach is for the federal government to provide financial assistance to support broadband deployment in underserved areas. Others, however, believe that federal assistance for broadband deployment is not appropriate. Some opponents question the reality of the “digital divide,” and argue that federal intervention in the broadband marketplace would be premature and, in some cases, counterproductive.

A comprehensive test ban treaty, or CTBT, is the oldest item on the nuclear arms control agenda. Three treaties currently limit testing to underground only, with a maximum force equal to 150,000 tons of TNT. According to the Natural Resources Defense Council, the United States conducted 1,030 nuclear tests, the Soviet Union 715, the United Kingdom 45, France 210, and China 45. The last U.S. test was held in 1992; the last U.K. test, in 1991. Russia claims it has not conducted nuclear tests since 1991.
