Great Lakes Initiative: EPA and States Have Made Progress, but Much Remains to Be Done If Water Quality Goals Are to Be Achieved
Testimony issued by the Government Accountability Office with an abstract that begins "Millions of people in the United States and Canada depend on the Great Lakes for drinking water, recreation, and economic livelihood. During the 1970s, it became apparent that pollutants discharged into the Great Lakes Basin from point sources, such as industrial and municipal facilities, or from nonpoint sources, such as air emissions from power plants, were harming the Great Lakes. Some of these pollutants, known as bioaccumulative chemicals of concern (BCC), pose risks to fish and other species as well as to the humans and wildlife that consume them. In 1995, the Environmental Protection Agency (EPA) issued the Great Lakes Initiative (GLI). The GLI established water quality criteria to be used by states to establish pollutant discharge limits for some BCCs and other pollutants that are discharged by point sources. The GLI also allows states to include flexible permit implementation procedures (flexibilities) that allow facilities' discharges to exceed GLI criteria. This testimony is based on GAO's July 2005 report, Great Lakes Initiative: EPA Needs to Better Ensure the Complete and Consistent Implementation of Water Quality Standards (GAO-05-829) and updated information from EPA and the Great Lakes states. This …

Defense Acquisitions: DOD's Increased Reliance on Service Contractors Exacerbates Long-standing Challenges
Testimony issued by the Government Accountability Office with an abstract that begins "The Department of Defense's (DOD) spending on goods and services has grown significantly since fiscal year 2000, to well over $314 billion annually. GAO has identified DOD contract management as a high-risk area for more than decade. With awards to contractors large and growing, DOD will continue to be vulnerable to contracting fraud, waste, or misuse of taxpayer dollars, and abuse. Prudence with taxpayer funds, widening deficits, and growing long-range fiscal challenges demand that DOD maximize its return on investment, while providing warfighters with the needed capabilities at the best value for the taxpayer. This statement discusses (1) the implications of DOD's increasing reliance on contractors to fill roles previously held by government employees, (2) the importance of the acquisition workforce in DOD's mission and the need to strengthen its capabilities and accountability, and (3) assumptions about cost savings related to the use of contractors versus federal employees. This statement is based on work GAO has ongoing or has completed over the past several years covering a range of DOD contracting issues."

Nuclear Security: Action May Be Needed to Reassess the Security of NRC-Licensed Research Reactors
A letter report issued by the Government Accountability Office with an abstract that begins "There are 37 research reactors in the United States, mostly located on college campuses. Of these, 33 reactors are licensed and regulated by the Nuclear Regulatory Commission (NRC). Four are operated by the Department of Energy (DOE) and are located at three national laboratories. Although less powerful than commercial nuclear power reactors, research reactors may still be attractive targets for terrorists. As requested, GAO examined the (1) basis on which DOE and NRC established the security and emergency response requirements for DOE and NRC-licensed research reactors and (2) progress that the National Nuclear Security Administration (NNSA) has made in converting U.S. research reactors that use highly enriched uranium (HEU) to low enriched uranium (LEU) fuel. This report summarizes the findings of GAO's classified report on the security of research reactors (GAO-08-156C)."

Audits of Public Companies: Continued Concentration in Audit Market for Large Public Companies Does Not Call for Immediate Action
A letter report issued by the Government Accountability Office with an abstract that begins "GAO has prepared this report under the Comptroller General's authority as part of a continued effort to assist Congress in reviewing concentration in the market for public company audits. The small number of large international accounting firms performing audits of almost all large public companies raises interest in potential effects on competition and the choices available to large companies needing an auditor. This report examines (1) concentration in the market for public company audits, (2) the potential for smaller accounting firms' growth to ease market concentration, and (3) proposals that have been offered by others for easing concentration and the barriers facing smaller firms in expanding their market shares. GAO surveyed a random sample of almost 600 large, medium, and small public companies on their experiences with their auditors. GAO also interviewed the four largest accounting firms and surveyed all other U.S. accounting firms that audit at least one public company. GAO also developed an econometric model that analyzed the extent to which various factors, including concentration and new auditing requirements, affected fee levels. To supplement this work, GAO interviewed market participants, including public companies, investors, …

Global War on Terrorism: Reported Obligations for the Department of Defense
Correspondence issued by the Government Accountability Office with an abstract that begins "Since 2001, Congress has provided the Department of Defense (DOD) with hundreds of billions of dollars in supplemental and annual appropriations for military operations in support of the Global War on Terrorism (GWOT). DOD's reported annual obligations for GWOT have shown a steady increase from about $0.2 billion in fiscal year 2001 to about $139.8 billion in fiscal year 2007. In fiscal year 2007, Congress provided DOD with about $161.8 billion in annual and supplemental appropriations3 for GWOT. To continue its GWOT operations, DOD has requested $189. billion in appropriations for fiscal year 2008. As of December 2007, Congress has provided DOD with about $86.8 billion for GWOT in fiscal year 2008, including $16.8 billion for Mine Resistant Ambush Protected vehicles. DOD has reported obligations of about $23.8 billion for GWOT for fiscal year 2008 through November 2007. The United States' commitments to GWOT will likely involve the continued investment of significant resources, requiring decision makers to consider difficult trade-offs as the nation faces an increasing long-range fiscal challenge. The magnitude of future costs will depend on several direct and indirect cost variables and, in some cases, decisions …

Federal Estate, Gift, and Generation-Skipping Taxes: A Description of Current Law
This report contains an explanation of the major provisions of the federal estate, gift, and generation-skipping transfer taxes. The discussion divides the federal estate tax into three components: the gross estate, deductions from the gross estate, and computation of the tax, including allowable tax credits. The federal estate tax is computed through a series of adjustments and modifications of a tax base known as the "gross estate." Certain allowable deductions reduce the gross estate to the "taxable estate," to which is then added the total of all lifetime taxable gifts made by the decedent. The tax rates are applied and, after reduction for certain allowable credits, the amount of tax owed by the estate is reached.

A History of Federal Estate, Gift, and Generation-Skipping Taxes
Three primary categories of legislation pertaining to transfer taxes have been introduced in the 110th Congress. As noted above, the repeal of the estate and generation-skipping taxes is not permanent. One category would make the repeal permanent. (See, H.R. 411 and H.R. 2380). Another category would accelerate the repeal of these transfer taxes. (See, H.R. 25, H.R. 1040, H.R. 1586, H.R. 4042, S. 1025, S. 1040, and S. 1081). The third would reinstate these taxes at lower rates and/or in a manner more considerate of family-owned business. (See, H.R. 1928, H.R. 3170, H.R. 3475, H.R. 4172, H.R. 4235, H.R. 4242, and S. 1994). In this report, the history of the federal transfer taxes has been divided into four parts: (1) the federal death and gift taxes used between 1789 and 1915; (2) the development, from 1916 through 1975, of the modern estate and gift taxes; (3) the creation and refinement of a unified estate and gift tax system, supplemented by a generation-skipping transfer tax; and (4) the phaseout and repeal of the estate and generation-skipping taxes, with the gift tax being retained as a device to protect the integrity of the income tax.

Summary of Workshop: Barriers to Energy Efficient Residential Ventilation
The objectives for this workshop were to bring together those with different viewpoints on the implementation of energy efficient ventilation in homes to share their perspectives. The primary benefit of the workshop is to allow the participants to get a broader understanding of the issues involved and thereby make themselves more able to achieve their own goals in this area. In order to achieve this objective each participant was asked to address four objectives from their point of view: (1) Drivers for energy efficient residential ventilation: Why is this an important issue? Who cares about it? Where is the demand: occupants, utilities, regulation, programs, etc? What does sustainability mean in this context? (2) Markets & Technologies: What products, services and systems are out there? What kinds of things are in the pipeline? What is being installed now? Are there regional or other trends? What are the technology interactions with other equipment and the envelope? (3) Barriers to Implementation: What is stopping decision makers from implementing energy-efficient residential ventilation systems? What kind of barriers are there: technological, cost, informational, structural, etc. What is the critical path? (4) Solutions: What can be done to overcome the barriers and how can/should we do …

PEM Fuel Cell Freeze Durability and Cold Start Project
UTC has taken advantage of the unique water management opportunities inherent in micro-porous bipolar-plates to improve the cold-start performance of its polymer electrolyte fuel cells (PEFC). Diagnostic experiments were used to determine the limiting factors in micro-porous plate PEFC freeze performance and the causes of any performance decay. Alternative cell materials were evaluated for their freeze performance. Freeze-thaw cycling was also performed to determine micro-porous plate PEFC survivability. Data from these experiments has formed the basis for continuing development of advanced materials capable of supporting DOE's cold-start and durability objectives.

Isothermal Martensitic and Pressure-Induced Delta to Alpha-Prime Phase Transformations in a Pu-Ga Alloy
A well-homogenized Pu-2 at.% Ga alloy can be retained in the metastable face-centered cubic {delta} phase at room temperature. Ultimately, this metastable {delta} phase will decompose via a eutectoid transformation to the thermodynamically stable monoclinic {alpha} phase and the intermetallic compound Pu{sub 3}Ga over a period of approximately 10,000 years [1]. In addition, these low solute-containing {delta}-phase Pu alloys are metastable with respect to an isothermal martensitic phase transformation to the {alpha}{prime} phase during low temperature excursions [2, 3] and are also metastable with respect to a {delta} {yields} {alpha}{prime} phase transformation with increases in pressure [3-5]. The low temperature {delta} {yields} {alpha}{prime} isothermal martensitic phase transformation in the Pu-2 at.% Ga alloy only goes to {approx}25% completion with the resultant {approx}20 {micro}m long by 2 {micro}m wide lath-shaped {alpha}{prime} particles dispersed within the {delta} matrix. In recently reported studies, Faure et al. [4] have observed a {delta} {yields} {gamma} {yields} {alpha}{prime} pressure-induced phase transformation sequence during a diamond anvil cell investigation and, based on x-ray diffraction and density and compressibility experiments, Harbur [5] has concluded that both {alpha}{prime} and an amorphous phase are present in samples that were pressurized and recovered. In this work, a large volume moissanite anvil …

The Exosporium of B.cereus Contains a Binding Site for gC1qR/p33: Implication in Spore Attachment and/or Entry
B. cereus, is a member of a genus of aerobic, gram-positive, spore-forming rod-like bacilli, which includes the deadly, B. anthracis. Preliminary experiments have shown that gC1qR binds to B.cereus spores that have been attached to microtiter plates. The present studies were therefore undertaken, to examine if cell surface gC1qR plays a role in B.cereus spore attachment and/or entry. Monolayers of human colon carcinoma (Caco-2) and lung cells were grown to confluency on 6 mm coverslips in shell vials with gentle swirling in a shaker incubator. Then, 2 {micro}l of a suspension of strain SB460 B.cereus spores (3x10{sup 8}/ml, in sterile water), were added and incubated (1-4 h; 36{sup 0} C) in the presence or absence of anti-gC1qR mAb-carbon nanoloops. Examination of these cells by EM revealed that: (1) When B. cereus endospores contacted the apical Caco-2 cell surface, or lung cells, gClqR was simultaneously detectable, indicating upregulation of the molecule. (2) In areas showing spore contact with the cell surface, gClqR expression was often adjacent to the spores in association with microvilli (Caco-2 cells) or cytoskeletal projections (lung cells). (3) Furthermore, the exosporia of the activated and germinating spores were often decorated with mAb-nanoloops. These observations were further corroborated by …
