This article discusses developments in environmental analytical chemistry that occurred in the years of 2003 and 2004. References were found by searching the ''Science Citation Index and Current Contents''. As in our review of two years ago (A1), techniques are highlighted that represent current trends and state-of-the-art technologies in the sampling, extraction, separation, and detection of trace concentrations, low-part-per-billion and less, of organic, inorganic, and organometallic contaminants in environmental samples. New analytes of interest are also reviewed, the detections of which are made possible by recently developed analytical instruments and methods.

The focus of the research project was to systematically assess the strain rate dependence of strengthening mechanisms in new advanced high strength sheet steels. Data were obtained on specially designed and produced Duel Phase and TRIP steels and compared to the properties of automotive steels currently in use.

Other written product issued by the Government Accountability Office with an abstract that begins "This is Appendix IV for GAO-05-454, entitled "Unfunded Mandates: Views Vary About Reform Act's Strengths, Weaknesses, and Options for Improvement.""

A letter report issued by the Government Accountability Office with an abstract that begins "The Unfunded Mandates Reform Act of 1995 (UMRA) was enacted to address concerns about federal statutes and regulations that require nonfederal parties to expend resources to achieve legislative goals without being provided federal funding to cover the costs. UMRA generates information about the nature and size of potential federal mandates on nonfederal entities to assist Congress and agency decision makers in their consideration of proposed legislation and regulations. However, it does not preclude the implementation of such mandates. At various times in its 10-year history, Congress has considered legislation to amend various aspects of the act to address ongoing questions about its effectiveness. Most recently, GAO was asked to consult with a diverse group of parties familiar with the act and to report their views on (1) the significant strengths and weaknesses of UMRA as the framework for addressing mandate issues and (2) potential options for reinforcing the strengths or addressing the weaknesses. To address these objectives, we obtained information from 52 organizations and individuals reflecting a diverse range of viewpoints. GAO analyzed the information acquired and organized it into broad themes for analytical and reporting …

Inertial Confinement Fusion (ICF) is an ideal technology to power self-contained single-stage piloted (manned) spacecraft within the solar system because of its inherently high power/mass ratios and high specific impulses (i.e., high exhaust velocities). These technological advantages are retained when ICF is utilized with a magnetic thrust chamber, which avoids the plasma thermalization and resultant degradation of specific impulse that are unavoidable with the use of mechanical thrust chambers. We started with Rod Hyde's 1983 description of an ICF-powered engine concept using a magnetic thrust chamber, and conducted a more detailed systems study to develop a viable, realistic, and defensible spacecraft concept based on ICF technology projected to be available in the first half of the 21st century. The results include an entirely new conical spacecraft conceptual design utilizing near-existing radiator technology. We describe the various vehicle systems for this new concept, estimate the missions performance capabilities for general missions to the planets within the solar system, and describe in detail the performance for the baseline mission of a piloted roundtrip to Mars with a 100-ton payload. For this mission, we show that roundtrips totaling {ge}145 days are possible with advanced DT fusion technology and a total (wet) spacecraft mass …
