Carbon dioxide is the major “greenhouse” gas responsible for global warming. Southeastern pine forests appear to be among the largest terrestrial sinks of carbon dioxide in the US. This collaborative study specifically addressed the isotopic signatures of the large fluxes of carbon taken up by photosynthesis and given off by respiration in this ecosystem. By measuring these isotopic signatures at the ecosystem level, we have provided data that will help to more accurately quantify the magnitude of carbon fluxes on the regional scale and how these fluxes vary in response to climatic parameters such as rainfall and air temperature. The focus of the MBL subcontract was to evaluate how processes operating at the physiological and ecosystem scales affects the resultant isotopic signature of plant waxes that are emitted as aerosols into the convective boundary layer. These wax aerosols provide a large-spatial scale integrative signal of isotopic discrimination of atmospheric carbon dioxide by terrestrial photosynthesis (Conte and Weber 2002). The ecosystem studies have greatly expanded of knowledge of wax biosynthetic controls on their isootpic signature The wax aerosol data products produced under this grant are directly applicable as input for global carbon modeling studies that use variations in the concentration and …

The National Museum of the Pacific War presents an oral interview with Paul Jackson. He begins by discussing his time in boot camp at Camp Pendelton. The majority of the interview is about his time fighting at Iwo Jima.

Minutes for the April 10, 2008 TXSSAR meeting, held by the McKinney chapter.

Testimony issued by the Government Accountability Office with an abstract that begins "The Future Combat System (FCS) program--which comprises 14 integrated weapon systems and an advanced information network--is the centerpiece of the Army's effort to transition to a lighter, more agile, and more capable combat force. The substantial technical challenges, the Army's acquisition strategy, and the cost of the program are among the reasons why the program is recognized as needing special oversight and review. This testimony is based on GAO's two March 2008 reports on FCS and addresses (1) how the definition, development, and demonstration of FCS capabilities are proceeding, particularly in light of the go/no-go decision scheduled for 2009; (2) the Army's plans for making production commitments for FCS and any risks related to the completion of development; and (3) the estimated costs for developing and producing FCS."

Testimony issued by the Government Accountability Office with an abstract that begins "The budget authority GAO is requesting for fiscal year 2009--$545.5 million--represents a prudent request of 7.5 percent to support the Congress as it confronts a growing array of difficult challenges. GAO will continue to reward the confidence you place in us by providing a strong return on this investment. In fiscal year 2007 for example, in addition to delivering hundreds of reports and briefings to aid congressional oversight and decisionmaking, our work yielded: financial benefits, such as increased collection of delinquent taxes and civil fines, totaling $45.9 billion--a return of $94 for every dollar invested in GAO; over 1,300 other improvements in government operations spanning the full spectrum of national issues, ranging from helping Congress create a center to better locate children after disasters to strengthening computer security over sensitive government records and assets to encouraging more transparency over nursing home fire safety to strengthening screening procedures for VA health care practitioners; and expert testimony at 276 congressional hearings to help Congress address a variety of issues of broad national concern, such as the conflict in Iraq and efforts to ensure drug and food safety."

Testimony issued by the Government Accountability Office with an abstract that begins "The high pace of overseas operations is taking a heavy toll on Army equipment. Harsh combat and environmental conditions over sustained periods of time have exacerbated equipment repair, replacement, and recapitalization problems. The Army has also taken steps to restructure its forces before implementing its longer term transformation to the Future Combat System. To support ongoing operations and prepare for the future, the Army has embarked on four key initiatives: (1) restructuring from a division-based force to a modular brigade-based force, (2) expanding the Army by adding about 74,000 people and creating new units, (3) repairing, replacing, and recapitalizing new equipment through its reset program, and (4) replacing equipment borrowed from its pre-positioned equipment sets around the world. Since 2004, Congress has provided billions of dollars to support the Army's equipping needs. GAO has issued many reports on the Army's efforts to equip modular units, expand the Army, reset equipment, and manage and replace prepositioned equipment. This statement, which draws largely on these reports, will address (1) the equipment-related cost of these initiatives, and (2) the management challenges facing the Army and the actions needed to improve its …

Testimony issued by the Government Accountability Office with an abstract that begins "Unauthorized individuals, companies, terrorist organizations, and other countries continue their attempts to obtain sensitive items related to the defense of the United States. The Internet is one place that defense-related items can be purchased, raising the possibility that some sensitive items are available to those who can afford them. In addition to the risk that sensitive defense-related items could be used to directly harm U.S. service members or allies on the battlefield, these items could be disassembled and analyzed (i.e., reverse engineered) to develop countermeasures or equivalent technology. Given the risks posed by the sale of sensitive defense-related items to the public, and the Internet's international reach and high volume of commerce, the Subcommittee asked GAO to conduct undercover testing to determine whether the general public can easily purchase these items on the Internet, including on the Web sites eBay and Craigslist. To perform this work, GAO investigators used undercover identities to pose as members of the general public, meaning that they conducted their work with names, credit cards, and contact information that could not be traced to GAO. Investigators interviewed sellers where possible and referred cases to …
