This report gives an overview of the American Opportunity Tax Credit (AOTC)—enacted on a temporary basis by the American Recovery and Reinvestment Act and extended through the end of 2012 by the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010— which is a partially-refundable tax credit that provides financial assistance to taxpayers who are attending college, or whose children are attending college. There are a variety of policy options mentioned in the report regarding the AOTC, including extending the credit, extending a modified AOTC, or repealing the Hope and Lifetime Credits and extending a modified AOTC that includes provisions included in these credits.

The following provides an assessment of an experimental platform based on the ORION laser at AWE Aldermasten, England, for measuring the opacity of high-temperature and high-density LTE plasmas. The specific points addressed are (1) the range of electron density and temperature that can be achieved with short-pulse beams alone, as well as (2) by means of compression with a long-pulse beam; (3) the accuracy with which electron density, electron temperature, and absolute emissivity can be measured; (4) the use of pulse shaping to increase the sample density to above solid density; (5) the effect that target materials and target design have on maintaining spatial uniformity of the sample, and (6) the need for additional diagnostics to produce and characterize samples for decisive measurements.

The report discusses how the EU's Emissions Trading Scheme Works, U.S. government actions and climate change.

This report looks at how the European Union Emission Trading Scheme's coverage of carbon emission from commercial flights affects air carriers from the United States and other countries.

This report provides a brief overview of the existing statutory authority and the regulation implementing this authority. It describes several policy issues raised in previous debates regarding chemical facility security and identifies policy options for congressional consideration. Finally, legislation in the 112th Congress is discussed.

This report discusses regulations from Congress on bundling, which refers to the consolidation of two or more requirements for goods or services previously provided or performed under separate smaller contracts into a solicitation for a single contract that is likely to be unsuitable for award to a small business because of its size or scope. It particularly looks at the Small Business Act and new legislation by the 112th Congress to expand the definition of bundling, strengthen the authority of the Administrator of Small Business, and requirements for reporting bundled procurements.

Sections 3.2.4 and 3.2.5 of the Handbook of Accelerator Physics and Engineering on Landau damping are combined and updated. The new addition includes impedances and wakes for multi-layer beam pipe, optical model, diffraction model, and cross-sectional transition.

This report looks at past gun control legislation and also how recent events (such as the shooting in Tucson, AZ on January 8, 2011 which notably wounded Rep. Gabrielle Giffords) have influenced current legislation. This report concludes with discussion of other salient and recurring gun control issues that have generated past congressional interest.

During irradiation of nuclear fuel in a reactor, the five metals, Mo, Pd, Rh, Ru, and Tc, migrate to the fuel grain boundaries and form small metal particles of an alloy known as epsilon metal ({var_epsilon}-metal). When the fuel is dissolved in a reprocessing plant, these metal particles remain behind with a residue - the undissolved solids (UDS). Some of these same metals that comprise this alloy that have not formed the alloy are dissolved into the aqueous stream. These metals limit the waste loading for a borosilicate glass that is being developed for the reprocessing wastes. Epsilon metal is being developed as a waste form for the noble metals from a number of waste streams in the aqueous reprocessing of used nuclear fuel (UNF) - (1) the {var_epsilon}-metal from the UDS, (2) soluble Tc (ion-exchanged), and (3) soluble noble metals (TRUEX raffinate). Separate immobilization of these metals has benefits other than allowing an increase in the glass waste loading. These materials are quite resistant to dissolution (corrosion) as evidenced by the fact that they survive the chemically aggressive conditions in the fuel dissolver. Remnants of {var_epsilon}-metal particles have survived in the geologically natural reactors found in Gabon, Africa, indicating …

A letter report issued by the Government Accountability Office with an abstract that begins "In examining the history of the Kachemak Bay ferry project, GAO found that the Seldovia Village Tribe’s federally funded ferry differs significantly from its original proposal. In 2002, the tribe proposed a vehicle and passenger ferry with year-round service between Homer, Alaska, on the north shore of Kachemak Bay and multiple southern ports, including the city of Seldovia. Federal funding was appropriated in fiscal years 2004, 2005, and 2006, from which about $8.5 million was provided to the tribe for a ferry. The state also provided $1.5 million. The tribe subsequently built a ferry and dock facilities that cost about $8.8 million, but the project was significantly more limited in scope and service than the original proposal. Specifically, the ferry, known as the Kachemak Voyager began operating in May 2010, but it only provided passenger and light-freight service between Homer and Seldovia and only during the summer months."

This Congressional Research Service Report for Congress details Medicare Hospital Insurance (HI) financing as well as history of solvency and current insolvency projections.

In June 2005, G8 finance ministers proposed the new Multilateral Debt Relief Initiative (MDRI). The MDRI proposes to cancel debts of some of the world's poorest countries owed to the International Monetary Fund, World Bank, and African Development Bank. This report discusses MDRI's implementation and raises some issues regarding debt relief's effectiveness as a form of foreign assistance for possible congressional consideration.

This report provides background information and potential oversight issues for Congress on the CVN-78 program. CVN-78, CVN-79, and CVN-80 are the first three ships in the Navy's new Gerald R. Ford (CVN- 78) class of nuclear-powered aircraft carriers (CVNs).
