The editors state in their introduction that this book is intended for lithium-ion scientists and engineers but they hope it may be of interest to scientists from other fields. Their main aim was to provide a snapshot of the state of the Lithium-ion art and in this they have largely succeeded. The book is comprised of a collection of very current reviews of the lithium ion battery literature by acknowledged experts that draw heavily on the authors' own research but are sufficiently general to provide the lithium ion researcher with enough guidance to the current literature and the current thinking in the field. Some of the literature references may be too current as there are numerous citations of conference proceedings which may be easily accessible to the lithium ion scientist or engineer but are not likely to be available to the interested chemist coming to the field for the first time. One author expresses the hope and expectation that properly peer-reviewed articles will appear in due course and the interested reader should look out for them in future. From the point of view of the lithium ion battery scientist and engineer, the book covers most of the topics that are …

Three-dimensional reconstruction of ribosome particles from electron micrographs requires selection of many single-particle images. Roughly 100,000 particles are required to achieve approximately 10 angstrom resolution. Manual selection of particles, by visual observation of the micrographs on a computer screen, is recognized as a bottleneck in automated single particle reconstruction. This paper describes an efficient approach for automated boxing of ribosome particles in micrographs. Use of a fast, anisotropic non-linear reaction-diffusion method to pre-process micrographs and rank-leveling to enhance the contrast between particles and the background, followed by binary and morphological segmentation constitute the core of this technique. Modifying the shape of the particles to facilitate segmentation of individual particles within clusters and boxing the isolated particles is successfully attempted. Tests on a limited number of micrographs have shown that over 80 percent success is achieved in automatic particle picking.

Over 160 acres (64.8 ha) of tree seedlings have been planted in eastern and western Kentucky that depict a mixed stand similar to the native vegetation of the area. All these sites have been assessed and various instrumentation is or is planned for installation to monitor environmental conditions and changes on the areas. The environmental conditions include temperature, aspect, slope, rainfall, and other treatment or condition factors.

Nickel based Alloy 22 (NO6022) is extensively used in aggressive industrial applications, especially due to its resistance to localized corrosion and stress corrosion cracking in high chloride environments. The purpose of this work was to characterize the anodic behavior of Alloy 22 in oxalic acid solution and to compare its behavior to sodium chloride (NaCl) solutions. Standard electrochemical tests such as polarization resistance and cyclic polarization were used. Results show that the corrosion rate of Alloy 22 in oxalic acid solutions increased rapidly as the temperature and the acid concentration increased. Extrapolation studies show that even at a concentration of 10{sup -4}M oxalic acid, the corrosion rate of Alloy 22 would be higher in oxalic acid than in 1 M NaCl solution. Alloy 22 was not susceptible to localized corrosion in oxalic acid solutions. Cyclic polarization tests in 1 M NaCl showed that Alloy 22 was susceptible to crevice corrosion at 90 C but was not susceptible at 60 C.

Congress supports the research and development efforts of the Department of Defense (DOD) with a Research, Development, Test and Evaluation (RDT&E) appropriation. The appropriation primarily supports the development of the nation’s future military hardware and software and the technology base upon which those products rely. It is the federal government’s single largest research and development account. Besides supporting the nation’s military needs, some of the technology developed with RDT&E funds spills over into the commercial sector. For these reasons, RDT&E funding draws a considerable amount of attention within Congress each year.

We conducted a series of four demonstrations to determine the ability of either monosodium titanate (MST) or permanganate (MnO4-) to remove strontium and actinides from salt solutions, under a variety of conditions. Each of the demonstrations used material derived from actual tank waste. The demonstrations used volumes as large as 68 L compared to typical prior experiments at 100 mL. Also, the study used, in two experiments, hydraulically scaled mixing conditions to match those of the equipment installed in Building 512-S for the Actinide Removal Process. (Plans call for radioactive commissioning of that facility as early as December 2003.)

The most common problems affecting residential and light commercial heating, ventilation, and air-conditioning (HVAC) systems are slow refrigerant leaks and dirty air filters. Equipment users are usually not aware of a problem until most of the refrigerant has escaped or the air filter is clogged with dirt. While a dirty air filter can be detected with a technology based on the air pressure differential across the filter, such as a ''whistling'' indicator, it is not easy to incorporate this technology into existing HVAC diagnostic equipment. Oak Ridge National Laboratory is developing a low-cost, nonintrusive refrigerant charge indicator and dirty air filter detection sensor. The sensors, based on temperature measurements, will be inexpensive and easy to incorporate into existing heat pumps and air conditioners. The refrigerant charge indicator is based on the fact that when refrigerant starts to leak, the evaporator coil temperature starts to drop and the level of liquid subcooling drops. When the coil temperature or liquid subcooling drops below a preset reading, a signal, such as a yellow warning light, can be activated to warn the equipment user that the system is undercharged. A further drop of coil temperature or liquid subcooling below another preset reading would trigger …

Among the current issues in U.S.-Egyptian relations are the shared concerns over the terrorist attacks against Egyptian police, religious, government, and tourist facilities, and what those attacks maysignal for Egypt’s domestic stability. The two nations may disagree over Egypt’s interpretation of applying human rights practices to Islamic terrorists. The two countries disagree over the speed and depth, but not the need for some of Egypt’s economic reforms. Egypt and the United States agree on the importance of the Egyptian-Israeli peace treaty, the need to continue current Arab-Israel peace talks, and the need for regional stability. The two nations agree on Egypt’s determination to introduce democratic reforms to Egypt.

The authors of this report, under the sponsorship of the U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE) Weatherization and Intergovernmental Program, have investigated the possible application of Energy Star ratings to passenger cars and light trucks. This study establishes a framework for formulating and evaluating Energy Star rating methods that is comprised of energy- and environmental-based metrics, potential vehicle classification systems, vehicle technology factors, and vehicle selection criteria. The study tests several concepts and Energy Star rating methods using model-year 2000 vehicle data--a spreadsheet model has been developed to facilitate these analyses. This study tests two primary types of rating systems: (1) an outcome-based system that rates vehicles based on fuel economy, GHG emissions, and oil use and (2) a technology-based system that rates vehicles based on the energy-saving technologies they use. Rating methods were evaluated based on their ability to select vehicles with high fuel economy, low GHG emissions, and low oil use while preserving a full range of service (size and acceleration) and body style choice. This study concludes that an Energy Star rating for passenger cars and light trucks is feasible and that several methods could be used to achieve reasonable …

Our current specific objectives are to use transgenic plants to control the chemical species, electrochemical state, and above ground binding of mercury to (a) prevent methylmercury from entering the food-chain, (b) remove mercury from polluted sites, and (c) hyperaccumulate mercury in above ground tissues for later harvest.

This paper describes batch laboratory experiments performed to evaluate uranium incorporation into aluminosilicate structures during synthesis. This research was conducted in response to plant problems related to the accumulation of uranium with aluminosilicates in low-level radioactive waste evaporators. We have found that conditions which favor precipitation of aluminosilicates also foster uranium solid precipitation, so it is difficult to attribute problems with uranium accumulation to say just the formation of the aluminosilicates. Infrared spectra shows that sodium uranates, uranium silicates and other uranium solids are formed during the synthesis of sodium aluminosilicates structures in the presence of uranium. Both amorphous and sodalite aluminosilcate phases, unlike zeolite A phase, show appreciable affinity for uranium incorporation during their formation in the presence of uranium.

Testimony issued by the General Accounting Office with an abstract that begins "GAO appeared before the Subcommittee on Courts, the Internet, and Intellectual Property, House Committee on the Judiciary to discuss the results of our review and assessment of case-related workload measures for district court and courts of appeals judges. Biennially, the Judicial Conference of the United States, the federal judiciary's principal policymaking body, assesses the judiciary's needs for additional judgeships. If the Conference determines that additional judgeships are needed, it transmits a request to Congress identifying the number, type (courts of appeals, district, or bankruptcy), and location of the judgeships it is requesting. In assessing the need for additional district and appellate court judgeships, the Judicial Conference considers a variety of information, including responses to its biennial survey of individual courts, temporary increases or decreases in case filings, and other factors specific to an individual court. However, the Conference's analysis begins with the quantitative case-related workload measures it has adopted for the district courts and courts of appeals--weighted case filings and adjusted case filings, respectively. These two measures recognize, to different degrees, that the time demands on judges are largely a function of both the number and complexity of …

Testimony issued by the General Accounting Office with an abstract that begins "Buses form the backbone of the nation's mass transit systems. About 58 percent of all mass transit users take the bus, and even in many cities with extensive rail systems, more people ride the bus than take the train. In recent years, innovative Bus Rapid Transit systems have gained attention as an option for transit agencies to meet their mass transit needs. These systems are designed to provide major improvements in the speed, reliability, and quality of bus service through barrier-separated bus-ways, high-occupancy vehicle lanes, or reserved lanes or other enhancements on arterial streets. The characteristics of Bus Rapid Transit systems vary considerably, but may include (1) improved physical facilities or specialized structures such as dedicated rights-of-way; (2) operating differences such as fewer stops and higher speeds; (3) new equipment such as more advanced, quieter, and cleaner buses; and (4) new technologies such as more efficient traffic signalization and real-time information systems. This testimony, which updates a report GAO issued in September 2001, provides (1) information on federal support for Bus Rapid Transit systems and (2) an overview of factors affecting the selection of Bus Rapid Transit as …

The recommended waste package (WP) design is described in BSC (2001a). The design includes a double-wall WP underneath a protective drip shield (DS) (BSC 2003a). The purpose of the process-level models developed in this report is to model dry oxidation (DOX), general corrosion (GC) and localized corrosion (LC) of the DS plate material, which is made of Ti Grade 7. The DS design also includes structural supports fabricated from Ti Grade 24. Degradation of Ti Grade 24 is not considered in this report. The DS provides protection for the waste package outer barrier (WPOB) both as a barrier to seepage water contact and a physical barrier to potential rockfall. This Model Report (MR) serves as a feed to the Integrated Waste Package Degradation Model (IWPD) analyses, and was developed in accordance with the Technical Work Plan (TWP) (BSC 2002a). The models contained in this report serve as a basis to determine whether or not the performance requirements for the DS can be met.

Polyelectrolyte materials have been developed for lithium battery systems in response to the severe problems due to salt concentration gradients that occur in composite electrodes (aka membrane-electrode assemblies). Comb branch polymer architectures are described which allow for grafting of appropriate anions on to the polymer and also for cross-linking to provide for appropriate mechanical properties. The interactions of the polymers with the electrode surfaces are critical for the performance of the system and some of the structural features that influence this will be described. Parallels with the fuel cell MEA structures exist and will also be discussed.

Accelerator magnet technology is currently dominated by the use of NbTi superconductor. New and more demanding applications for superconducting accelerator magnets require the use of alternative materials. Several programs in the US are taking advantage of recent improvements in Nb{sub 3}Sn to develop high field magnets for new applications. Highlights and challenges of the US R&D program are presented along with the status of conductor development. In addition, a new R&D focus, the US LHC Accelerator Research Program, will be discussed.

Testimony issued by the General Accounting Office with an abstract that begins "Since 1996, GAO has reported that poor information security in the federal government is a widespread problem with potentially devastating consequences. Further, GAO has identified information security as a governmentwide high-risk issue in reports to the Congress since 1997--most recently in January 2003. To strengthen information security practices throughout the federal government, information security legislation has been enacted. This testimony discusses efforts by federal departments and the administration to implement information security requirements mandated by law. In so doing, it examines overall information security weaknesses and challenges that the government faces, and the status of actions to address them, as reported by the Office of Management and Budget (OMB). GAO's evaluation of agency efforts to implement federal information security requirements and correct identified weaknesses. New requirements mandated by the Federal Information Security Management Act of 2002 (FISMA)."

The effect of laser energy on formation of a plasma inside a cavity was investigated. The temperature and electron number density of laser-induced plasmas in a fused silica cavity were determined using spectroscopic methods, and compared with laser ablation on a flat surface. Plasma temperature and electron number density during laser ablation in a cavity with aspect ratio of 4 increased faster with irradiance after the laser irradiance reached a threshold of 5 GW/cm{sup 2}. The threshold irradiance of particulate ejection was lower for laser ablation in a cavity compared with on a flat surface; the greater the cavity aspect ratio, the lower the threshold irradiance. The ionization of silicon becomes saturated and the crater depths were increased approximately by an order of magnitude after the irradiance reached the threshold. Phase explosion was discussed to explain the large change of both plasma characteristics and mass removal when irradiance increased beyond a threshold value. Self-focusing of the laser beam was discussed to be responsible for the decrease of the threshold in cavities.

Testimony issued by the General Accounting Office with an abstract that begins "Both the Congress and the Department of Defense are concerned about the age of the U.S. aerial refueling fleet and its potential impact on the military services' ability to meet operational requirements. Aerial refueling provides a key capability that is essential to the mobility of U.S. forces. At present, the Air Force is in the early stages of planning for modernizing its aging fleet. In this testimony, GAO was asked to present its initial observations on (1) the status of the KC-135 fleet, including its age, projected life limits, and mission capable rates (i.e., the percent of time on average that the aircraft are available to perform their assigned mission); and (2) Air Force aerial refueling requirements."
