The development of metallic glasses in bulk form has led to a resurgence of interest into the utilization of these materials for a variety of applications. A potentially exciting application for these bulk metallic glass (BMG) materials is their use as composite membranes to replace high cost Pd/Pd-alloy membranes for enhanced gas separation processes. One of the major drawbacks to the industrial use of Pd/Pd-alloy membranes is that during cycling above and below a critical temperature an irreversible change takes place in the palladium lattice structure which can result in significant damage to the membrane. Furthermore, the cost associated with Pd-based membranes is a potential detractor for their continued use and BMG alloys offer a potentially attractive alternative. Several BMG alloys have been shown to possess high permeation rates, comparable to those measured for pure Pd metal. In addition, high strength and toughness when either in-situ or ex-situ second phase dispersoids are present. Both of these properties, high permeation and high strength/toughness, potentially make these materials attractive for gas separation membranes that could resist hydrogen 'embrittlement'. However, a fundamental understanding of the relationship between partially crystalline 'structure'/devitrification and permeation/embrittlement in these BMG materials is required in order to determine the …

The Convention on the Rights of the Child (CRC) is an international treaty that addresses the rights of children worldwide. It calls on States Parties to take all appropriate measures to ensure that children receive special rights, including the right to a name and nationality; access to healthcare, education, and parental care; and protection from exploitation, abuse, and neglect. This report provides a brief history of the Convention and outlines its objectives and structure, including the role and responsibilities of the treaty's monitoring body, the Committee on the Rights of the Child. It examines U.S. policy toward CRC, including the positions of past and current Administrations and congressional perspectives. The report also addresses selected policy issues that the 111th Congress may wish to take into account if considering ratification of CRC-- including the treaty's possible impact on U.S. sovereignty, federal and state laws, and parental rights. Other issues for possible consideration include the effectiveness of the Convention in protecting children's rights, and its role as a U.S. foreign policy instrument.

This report discusses Burma first parliamentary elections in 20 years. The elections are to be held under a new constitution, supposedly approved in a national referendum held in 2008 in the immediate aftermath of the widespread destruction caused by Cyclone Nargis.

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Health and Human Services (HHS) awards grants to provide shelter and services to runaway and homeless youth through the Basic Center, Transitional Living and Street Outreach Programs. In response to a mandate for a review of the grant award process for these programs in the Reconnecting Homeless Youth Act of 2008 (Pub. L. No. 110-378), GAO examined (1) grant announcements and application requirements, (2) technical assistance for grant applicants, (3) how grant award decisions are made, and (4) notification of grant award decisions. GAO reviewed requirements, documents, and records associated with this process for fiscal years 2007 and 2008, observed the grant evaluation portion of this process, and interviewed applicants, peer reviewers, and agency officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The Internal Revenue Service's (IRS) Business Systems Modernization (BSM) program is a multi-billion dollar, high risk, highly complex effort that involves the development and delivery of a number of modernized systems that are intended to replace the agency's aging business and tax processing systems. As required, IRS submitted its fiscal year 2010 expenditure plan in November 2009 to the House and Senate appropriations committees, requesting approximately $254 million from the BSM account. GAO's objectives in reviewing the expenditure plan were to (1) determine whether it satisfies the applicable legislative conditions, (2) determine IRS's progress in implementing prior expenditure plan review recommendations, and (3) provide additional observations about the plan and the BSM program. To accomplish the objectives, GAO analyzed the plan, reviewed related documentation, and interviewed IRS officials."
