911 Services: Most States Used 911 Funds for Intended Purposes, but FCC Could Improve Its Reporting on States' Use of Funds
A letter report issued by the Government Accountability Office with an abstract that begins "Although states faced challenges and delays in the past, states have made significant progress implementing wireless Enhanced 911 (E911) since 2003. Wireless E911 deployment usually proceeds through two phases: Phase I provides general caller location information by identifying the cell tower or cell site that is receiving the wireless call; Phase II provides more precise caller-location information, usually within 50 to 300 meters. Currently, according to the National Emergency Number Association (NENA), nearly 98 percent of 911 call centers, known as Public Safety Answering Points (PSAPs), are capable of receiving Phase I location information, and 97 percent have implemented Phase II for at least one wireless carrier. This represents a significant improvement since 2003 when implementation of Phase I was 65 percent and Phase II was 18 percent. According to NENA's current data, 142 U.S. counties (representing roughly 3 percent of the U.S. population) do not have some level of wireless E911 service. The areas that lack wireless E911 are primarily rural and tribal areas that face special implementation challenges, according to federal and association officials."

230Th-234U Age-Dating Uranium by Mass Spectrometry
This is the standard operating procedure used by the Isotope Ratio Mass Spectrometry Group of the Chemical Sciences Division at LLNL for the preparation of a sample of uranium oxide or uranium metal for {sup 230}Th-{sup 234}U age-dating. The method described here includes the dissolution of a sample of uranium oxide or uranium metal, preparation of a secondary dilution, spiking of separate aliquots for uranium and thorium isotope dilution measurements, and purification of uranium and thorium aliquots for mass spectrometry. This SOP may be applied to uranium samples of unknown purity as in a nuclear forensic investigation, and also to well-characterized samples such as, for example, U{sub 3}O{sub 8} and U-metal certified reference materials. The sample of uranium is transferred to a quartz or PFA vial, concentrated nitric acid is added and the sample is heated on a hotplate at approximately 100 C for several hours until it dissolves. The sample solution is diluted with water to make the solution approximately 4 M HNO{sub 3} and hydrofluoric acid is added to make it 0.05 M HF. A secondary dilution of the primary uranium solution is prepared. Separate aliquots for uranium and thorium isotope dilution measurements are taken and spiked with …

Active Climate Stabilization: Practical Physics-Based Approaches to Prevention of Climate Change
We offer a case for active technical management of the radiative forcing of the temperatures of the Earth's fluid envelopes, rather than administrative management of atmospheric greenhouse gas inputs, in order to stabilize both the global- and time-averaged climate and its mesoscale features. We suggest that active management of radiative forcing entails negligible--indeed, likely strongly negative--economic costs and environmental impacts, and thus best complies with the pertinent mandate of the UN Framework Convention on Climate Change. We propose that such approaches be swiftly evaluated in sub-scale in the course of an intensive international program.

African Development Bank and Fund
The African Development Bank Group, including the Bank itself (AfDB) and its “soft-loan” affiliate, the African Development Fund (AfDF), is a development finance institution based in Abidjan, Côte d’Ivoire. The Bank has 53 African members, as well as 24 non-regional members, including the United States. In the mid-1990s, the Bank faced management problems and difficulties arising from non-performing loans, but reforms launched in 1995 by a new Bank president, Omar Kabbaj, brought new pledges of support from the non-regionals. U.S. contributions to the Fund resumed in FY1998 and to the Bank in FY2000. This report will be updated as events warrant.

Air Emissions and Electricity Generation at U.S. Power Plants
Correspondence issued by the Government Accountability Office with an abstract that begins "Older electricity generating units—those that began operating in or before 1978—provided 45 percent of electricity from fossil fuel units in 2010 but produced a disproportionate share of emissions, both in aggregate and per unit of electricity generated. Overall, in 2010 older units contributed 75 percent of sulfur dioxide emissions, 64 percent of nitrogen oxides emissions, and 54 percent of carbon dioxide emissions from fossil fuel units. For each unit of electricity generated, older units collectively emitted about 3.6 times as much sulfur dioxide, 2.1 times as much nitrogen oxides, and 1.3 times as much carbon dioxide as newer units. The difference in emissions between older units and their newer counterparts may be attributed to a number of factors. First, 93 percent of the electricity produced by older fossil fuel units in 2010 was generated by coal-fired units. Compared with natural gas units, coal-fired units produced over 90 times as much sulfur dioxide, twice as much carbon dioxide and over five times as much nitrogen oxides per unit of electricity, largely because coal contains more sulfur and carbon than natural gas. Second, fewer older units have installed emissions controls, …

Analysis of an automatic control to prevent rolling divergence
From Introduction: "The use of automatic controls to reduce the tendency for rolling divergence has been investigated in references 2 and 3. These studies have considered the effect of artificial changes in certain stability derivatives on the rolling divergence, and have shown that increased damping in pitch may be quite effective in reducing the divergent tendency. In the present report, a different type of automatic control is investigated."

Applications of in situ gamma-ray spectrometry. [Monitoring radionuclides in soil]
Gamma-ray spectrometric methods using high-resolution Ge(Li) and high purity Ge detectors have been used to quantify the concentrations and external exposure rates of radionuclides in the soil. These in situ methods have been used to study radionuclide deposition around nuclear power stations, the distribution of radionuclides at the Nevada Test Site, biogeochemical cycling of radionuclides, and the fate and impact of fallout radionuclides. Portable gamma-ray spectrometer systems used for various kinds of in situ field measurements include: large-volume coaxial Ge(Li) detectors for terrestrial gamma-ray surveys at several sites including preoperational nuclear power plants and for real-time measurements of nuclear reactor plume isotopic exposure rates; and planar, high purity Ge detectors for mapping /sup 241/Am and /sup 239/Pu soil concentrations, particularly at the Nevada Test Site. These applications are discussed along with a brief description of the methodology and techniques associated with in situ gamma-ray spectrometry.

Assessment of high temperature nuclear energy storage systems for the production of intermediate and peak-load electric power
Increased cost of energy, depletion of domestic supplies of oil and natural gas, and dependence on foreign suppliers, have led to an investigation of energy storage as a means to displace the use of oil and gas presently being used to generate intermediate and peak-load electricity. Dedicated nuclear thermal energy storage is investigated as a possible alternative. An evaluation of thermal storage systems is made for several reactor concepts and economic comparisons are presented with conventional storage and peak power producing systems. It is concluded that dedicated nuclear storage has a small but possible useful role in providing intermediate and peak-load electric power.

Aviation Fees: Review of Air Carriers' Year 2000 Passenger and Property Screening Costs
A letter report issued by the Government Accountability Office with an abstract that begins "The Aviation and Transportation Security Act (ATSA) authorized the Transportation Security Administration (TSA) to impose an Aviation Security Infrastructure Fee (ASIF) on air carriers to help pay for the costs of aviation security services. To impose the ASIF, TSA issued an Interim Final Rule (IFR) and required air carriers to report their passenger and property screening costs incurred in 2000 on an attachment to the IFR referred to as Appendix A. The 2000 screening costs reported by air carriers were going to be used to establish the ASIF. Based on industry estimates of $1 billion, TSA had estimated that the costs incurred by air carriers in 2000 were $750 million, but the amounts reported by air carriers totaled $319 million, significantly less than expected. To provide the Congress with an independent assessment, the Department of Homeland Security Appropriations Act, 2005 required GAO to review the amount of passenger and property screening costs incurred by air carriers in 2000."
