Afghanistan: Post-War Governance, Security, and U.S. Policy

Afghanistan's planned political transition was completed with the convening of a parliament in December 2005, but insurgent threats to Afghanistan's government persist and are even growing in some southern provinces. A new constitution was adopted in January 2004, and successful presidential elections were held on October 9, 2004, followed by parliamentary elections on September 18, 2005. Afghan citizens are enjoying new personal freedoms that were forbidden under the Taliban. Women are participating in economic and political life; however, the insurgency led by remnants of the former Taliban regime has conducted numerous lethal attacks since mid-2005, narcotics trafficking is rampant, and independent militias remain through the country. U.S. stabilization measures focus on strengthening the central government and its security forces while combating insurgents.

Afghanistan: Post-War Governance, Security, and U.S. Policy

The United States and its allies are helping Afghanistan emerging from more than 22 years of warfare, although substantial risk to Afghan stability remains. Before the U.S. military campaign against the orthodox Islamist Taliban movement began on October 7, 2001, Afghanistan had been mired in conflict since the Soviet invasion of Afghanistan in 1979. The defeat of the Taliban has enabled the United States and its coalition partners to send forces throughout Afghanistan to search for Taliban and Al Qaeda fighters and leaders that remain at large, including Osama bin Laden. As the war against remaining Al Qaeda and Taliban elements winds down, the United States is shifting its military focus toward stabilizing the interim government, including training a new Afghan national army, and supporting the international security force (ISAF) that is helping the new government provide security.

Air Traffic Control: Status of the Current Modernization Program and Planning for the Next Generation System

A statement of record issued by the Government Accountability Office with an abstract that begins "Over a decade ago, GAO listed the Federal Aviation Administration's (FAA) effort to modernize the nation's air traffic control (ATC) system as a high-risk program because of systemic management and acquisition problems. Two relatively new offices housed within FAA--the Air Traffic Organization (ATO) and the Joint Planning and Development Office (JPDO)--are now primarily responsible for planning and implementing these modernization efforts. Congress created ATO to be a performance-based organization that would improve both the agency's culture, structure, and processes, and the ATC modernization program's performance and accountability. Congress created JPDO, made up of seven partner agencies, to coordinate the federal and nonfederal stakeholders necessary to plan a transition from the current air transportation system to the "next generation air transportation system" (NGATS). This statement is based on GAO's recently completed and ongoing studies of the ATC modernization program. GAO provides information on (1) the status of ATO's efforts to improve the ATC modernization program, (2) the status of JPDO's planning efforts for NGATS, and (3) actions to control costs and leverage resources for ATC modernization and the transformation to NGATS."

Applying Science and Technology to Combat WMD Terrorism (open access)

Applying Science and Technology to Combat WMD Terrorism

Lawrence Livermore National Laboratory (LLNL) is developing and fielding advanced strategies that dramatically improve the nation's capabilities to prevent, prepare for, detect, and respond to terrorist use of chemical, biological, radiological, nuclear, and explosive (CBRNE) weapons. The science, technology, and integrated systems we provide are informed by and developed with key partners and end users. LLNL's long-standing role as one of the two principle U.S. nuclear weapons design laboratories has led to significant resident expertise for health effects of exposure to radiation, radiation detection technologies, characterization of radioisotopes, and assessment and response capabilities for terrorist nuclear weapons use. This paper provides brief overviews of a number of technologies developed at LLNL that are being used to address national security needs to confront the growing threats of CBRNE terrorism.

Coastal Louisiana Ecosystem Restoration After Hurricanes Katrina and Rita (open access)

Coastal Louisiana Ecosystem Restoration After Hurricanes Katrina and Rita

Prior to Hurricanes Katrina and Rita, the U.S. Army Corps of Engineers had been seeking congressional approval for a $1.1 billion multi-year program to both construct five projects that would help to restore specified sites in the coastal wetland ecosystem in Louisiana, and to continue planning several other related projects. The state of Louisiana and several federal agencies have participated in the development of this program. This report introduces this program and restoration options that are being discussed in the wake of the hurricanes. It also discusses whether this program, if completed, might have muted the impacts of these hurricanes.

Distinguishing Monosaccharide Stereo- and Structural Isomers with ToF-SIMS and Multivariate Statistical Analysis (open access)

Distinguishing Monosaccharide Stereo- and Structural Isomers with ToF-SIMS and Multivariate Statistical Analysis

Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) is utilized to examine the mass spectra and fragmentation patterns of seven isomeric monosaccharides. Multivariate statistical analysis techniques, including principal component analysis (PCA), allow discrimination of the extremely similar mass spectra of stereoisomers. Furthermore, PCA identifies those fragment peaks which vary significantly between spectra. Heavy isotope studies confirm that these peaks are indeed sugar fragments, allow identification of the fragments, and provide clues to the fragmentation pathways. Excellent reproducibility is shown by multiple experiments performed over time and on separate samples. This study demonstrates the combined selectivity and discrimination power of ToF-SIMS and PCA, and suggests new applications of the technique including differentiation of subtle chemical changes in biological samples that may provide insights into cellular processes, disease progress, and disease diagnosis.

Final Scientific/Technical Report (open access)

Final Scientific/Technical Report

The overall goal of this project was to establish an education and training program in biobased products at Iowa State University (ISU). In particular, a graduate program in Biorenewable Resources and Technology (BRT) was to be established as a way of offering students advanced study in the use of plant- and crop-based resources in the production of biobased products. The program was to include three fundamental elements: an academic program, a research program, and industrial interactions. The academic program set out to introduce a new graduate major in Biorenewable Resources and Technology. Unlike other schools, which only offer certificates or areas of emphasis in biobased products, Iowa State University offers both M.S. and Ph.D degrees through its graduate program. Core required courses in Biorenewable Resources and Technology include a foundation course entitled Fundamentals of Biorenewable Resources (BRT 501); a seminar course entitled Biobased Products Seminar (BRT 506); a laboratory course, and a special topics laboratory course. The foundation course is a three-credit course introducing students to basic concepts in biorenewable resources and technology.

Futures Markets: Approach for Examining Oversight of Energy Futures

Testimony issued by the Government Accountability Office with an abstract that begins "Record high crude oil and natural gas prices have generated significant concerns by the public and members of Congress that the high and relatively volatile prices may be the result of factors other than market forces. Several members of the House and the Senate have expressed concerns over the upward trending prices and factors that may be causing the perceived increases in volatility of several energy commodities, including crude oil, gasoline, natural gas, and heating oil. As a result, we initiated this study under the authority of the Comptroller General. This testimony focuses on our ongoing study of (1) changes in energy futures markets and volatility since 2000 and (2) Commodity Futures Trading Commission (CFTC) surveillance and enforcement activities in the oversight of energy futures trading."

GeV electron beams from a cm-scale accelerator (open access)

GeV electron beams from a cm-scale accelerator

GeV electron accelerators are essential to synchrotron radiation facilities and free electron lasers, and as modules for high-energy particle physics. Radio frequency based accelerators are limited to relatively low accelerating fields (10-50 MV/m) and hence require tens to hundreds of meters to reach the multi-GeV beam energies needed to drive radiation sources, and many kilometers to generate particle energies of interest to the frontiers of high-energy physics.Laser wakefield accelerators (LWFA) in which particles are accelerated by the field of a plasma wave driven by an intense laser pulse produce electric fields several orders of magnitude stronger (10-100 GV/m) and so offer the potential of very compact devices. However, until now it has not been possible to maintain the required laser intensity, and hence acceleration, over the several centimeters needed to reach GeV energies.For this reason laser-driven accelerators have to date been limited to the 100 MeV scale. Contrary to predictions that PW-class lasers would be needed to reach GeV energies, here we demonstrate production of a high-quality electron beam with 1 GeV energy by channeling a 40 TW peak power laser pulse in a 3.3 cm long gas-filled capillary discharge waveguide. We anticipate that laser-plasma accelerators based on capillary discharge …

Haiti: Developments and U.S. Policy Since 1991 and Current Congressional Concerns

Following elections that were widely heralded as the first free and fair elections in Haiti's then-186-year history, Jean-Bertrand Aristide first became Haitian President in February 1991. Elections held under Aristide and his successor, Rene Preval (1996-2000), including the one in which Aristide was reelected in 2000, were marred by alleged irregularities, low voter turnout, and opposition boycotts. Congressional concerns regarding Haiti include fostering stability and democratic development, the cost and effectiveness of U.S. assistance, protection of human rights, improvement of security conditions, combating narcotics trafficking, addressing Haitian migration, and alleviating poverty.

Hurricane Katrina: Improving Federal Contracting Practices in Disaster Recovery Operations (open access)

Hurricane Katrina: Improving Federal Contracting Practices in Disaster Recovery Operations

Testimony issued by the Government Accountability Office with an abstract that begins "The devastation experienced throughout the Gulf Coast region in the wake of Hurricanes Katrina and Rita has called into question the government's ability to effectively respond to such disasters. The government needs to understand what went right and what went wrong, and to apply these lessons to strengthen its disaster response and recovery operations. The federal government relies on partnerships across the public and private sectors to achieve critical results in preparing for and responding to natural disasters, with an increasing reliance on contractors to carry out specific aspects of its missions. This testimony discusses how three agencies--the General Services Administration, the Federal Emergency Management Agency (FEMA), and the U.S. Army Corps of Engineers (the Corps)--conducted oversight of 13 key contracts awarded to 12 contractors for hurricane response, as well as public and private sector practices GAO identified that provide examples of how the federal government could better manage its disaster-related procurements."

Innovative Electromagnetic Sensors for Pipeline Crawlers Progress Report: October 2005 - March 2006 (open access)

Innovative Electromagnetic Sensors for Pipeline Crawlers Progress Report: October 2005 - March 2006

Internal inspection of pipelines is an important tool for ensuring safe and reliable delivery of fossil energy products. Current inspection systems that are propelled through the pipeline by the product flow cannot be used to inspect all pipelines because of the various physical barriers they encounter. Recent development efforts include a new generation of powered inspection platforms that crawl slowly inside a pipeline and are able to maneuver past the physical barriers that can limit inspection. At Battelle, innovative electromagnetic sensors are being designed and tested for these new pipeline crawlers. The various sensor types can be used to assess a wide range of pipeline anomalies including corrosion, mechanical damage, and cracks. Battelle is in the final year on a projected three-year development effort. In the first year, two innovative electromagnetic inspection technologies were designed and tested. Both were based on moving high-strength permanent magnets to generate inspection energy. One system involved translating permanent magnets towards the pipe. A pulse of electric current would be induced in the pipe to oppose the magnetization according to Lenz's Law. The decay of this pulse would indicate the presence of defects in the pipe wall. This inspection method is similar to pulsed eddy …
