It is often argued that paleoclimate studies are necessary to determine whether climate models and their predictions of future climate change can be trusted. An overall measure of the sensitivity of global mean surface temperature to a given radiative perturbation is provided by the global climate sensitivity parameter. In climate model experiments, this parameter appears to be moderately independent of the cause of the perturbation [see, for example, Hansen et al. (1997) and Hewitt and Mitchell (1997)], but it may differ from one model to the next by as much as a factor of three (IPCC, 1995). Moreover, there are some scientists who claim that all models are much more sensitive than the climate system itself (Lindzen, 1997). Thus it would be valuable to determine which models (if any) are consistent with the paleoclimate record and what factors are responsible for model differences in sensitivity. In an analysis of the Paleoclimate Modeling Intercomparison Project (PMIP) simulations of the Last Glacial Maximum (LGM) of 21,000 years ago, we have calculated how the ''forcing'' and feedbacks determine the climatic response. In the PMIP context, the ice sheet distribution is prescribed and the resulting increase in planetary albedo is the most important ''forcing'' …

A letter report issued by the General Accounting Office with an abstract that begins "Instructor shortages are affecting the quality and quantity of Army truck driver training. Fort Leonard Wood, which trains about 90 percent of truck drivers, is especially affected by the instructor shortage. The result is that student drivers are not fully trained in all aspects of the instruction program when they graduate. If formal schools had enough instructors, they would presumably be able to teach the entire instruction program. The student imbalance between the schools at Fort Leonard Wood and Fort Bliss creates an ineffective use of resources. If the annual student load were more equally distributed between the two schools, student graduates from Fort Leonard Wood might receive more complete training. The formal schools are not adhering to the instruction program, which calls for some training with trucks carrying cargo. Furthermore, no training is provided on how to pull equipment. Similarly, students are not being trained to drive under different weather and surface conditions. Because annual check rides and sustainment are not always being performed, unsafe driving habits may go undetected. Although performing and recording check rides and sustainment may be time-consuming, these procedures can save …

The goal of this project was to develop tools to facilitate data transformations between heterogeneous data sources found throughout biomedical applications. Such transformations are necessary when sharing data between different groups working on related problems as well as when querying data spread over different databases, files and software analysis packages.

As part of the effort to modernize safeguards equipment, the IAEA is continuing to acquire and install equipment for upgrading obsolete surveillance systems with digital technology; and providing remote-monitoring capabilities where and when economically justified. Remote monitoring is expected to reduce inspection effort, particularly at storage facilities and reactor sites. Remote monitoring technology will not only involve surveillance, but will also include seals, sensors, and other unattended measurement equipment. LLNL's experience with the Argus Security System offers lessons for the design, deployment, and maintenance of remote monitoring systems. Argus is an integrated security system for protection of high-consequence U.S. Government assets, including nuclear materials. Argus provides secure transmission of sensor data, administrative data, and video information to support intrusion detection and access control functions. LLNL developed and deployed the Argus system on its own site in 1988. Since that time LLNL has installed, maintained, and upgraded Argus systems at several Department of Energy and Department of Defense sites in the US as well as at the original LLNL site. Argus has provided high levels of reliability and integrity, as well as reducing overall lifecycle cost through incremental improvements to hardware and software. This philosophy permits expansion of functional capability, hardware …

Useful mineral by-products can be produced from geothermal brines. Although silica has many commercial uses, problems remain in producing a marketable product. We are conducting laboratory and modeling studies aimed at optimizing for rubber additive use, the properties of silica precipitates from Salton Sea and Coso-like geothermal fluids, Our goal is to develop a robust technique for producing silicas that have desirable physical and chemical properties for commercial use, while developing a generic understanding of silica precipitation that will allow extraction to be extended to additional fluid types, and to be easily modified to produce new types of marketable silica. Our experiments start with an acidified geothermal fluid similar to those treated by pH modification technology. Silica precipitation is induced by adding base and/or adding Mg or Ca salts to affect the nature of the precipitate. For the analog Salton Sea fluids, adding base alone caused silica to precipitate fairly rapidly. To date, we have characterized precipitates from experiments in which the final pH varied from 4 to 8, where NaOH and Na{sub 2}C0{sub 3} were added as bases, and CaCl{sub 2} and MgCl{sub 2} were added as salts. SEM photos of the silica precipitates from the Salton Sea and …

A letter report issued by the General Accounting Office with an abstract that begins "Because of concerns about the long-term budgetary implications associated with the environmental cleanup of the Department of Defense (DOD) training ranges, GAO examined (1) the potential magnitude of the cost to clean up these ranges in compliance with applicable laws and regulations, (2) the scope and reliability of DOD's training range inventory, and (3) the methodologies used to develop cost estimates. GAO found that DOD lacks complete and accurate data with which to estimate training range cleanup costs. DOD has not done a complete inventory of its ranges to fully identify the types and extent of unexploded ordnance present and the associated contamination. Recently, DOD began to compile training range data, but these initial efforts have been delayed because DOD did not issue formal guidance to the services for collecting the information until October 2000. Because DOD has not completed an inventory of its ranges, the services have used varying methods to estimate the size and condition of the ranges necessary to estimate the cost of cleanup for financial statement purposes. As a result, environmental liability costs are not consistently calculated and reported across the services."

The international scientific community recognizes that greenhouse gases have the potential to influence climate, and that potential changes in sea level and weather patterns would be largely deleterious. Because CO{sub 2} is emitted in such large quantities and its atmospheric concentration has been consistently rising throughout the recent past, it is only prudent to focus attention on reducing its emission and on developing strategies for its removal from the atmosphere [1]. A variety of removal methods have been suggested ranging from deep-sea disposal, to recycling to methanol, and to conversion to solid carbonate [2]. Problems appear to remain with all these strategies, and more work is needed to develop an acceptable, efficient method or set of methods. The idea of converting the gas to solid carbonate is particularly appealing, because on a human time scale, this is permanent disposal. The reaction of CO{sub 2} and water with unstable silicate minerals to produce more stable silicates (e.g., clays) and solid carbonates is the natural weathering process which is a dominant part of the long-term global geochemical cycling process (e.g., [3]). The Earth's large deposits of limestone and dolomite (the two primary forms of carbonate rock) represent the Earth's natural response to …

First identical-pion correlations measured at RHIC energies by PHENIX are presented. Two analyses with separate detectors, systematics, and statistics provide consistent results. The resulting HBT radii are moderately larger than those measured at lower energies. The k{sub t} dependence of the Bertsch-Pratt HBT radii is also similar to previous measures and is consistent with the conjecture of an expanding source.

The goals of this project were to establish database access to several databases of interest, customizing bioJava for database applications, improving performance of bioJava applets, development of additional applets, and maintenance of GenLang for web applications.

THE FRACTURE TOUGHNESS OF 6.4 mm (0.25 INCH) LOW CARBON ARC-CAST (LCAC) MOLYBDENUM AND ARC-CAST MOLYBDENUM-TZM ALLOY PLATE WERE MEASURED AT ROOM TEMPERATURE AND 300 DEGREES C USING COMPACT TNESION SPECIMENTS. THE EFFECT OF CRACK PLANE ORIENTATION (LONGITUDINAL VS. TRANSVERSE) AND ANNEALING PRACTICE (STRESS-RELIEVED VS. RECRYSTALLIZED) WERE EVALUATED. DEPENDING UPON THE TEST TEMPERATURE EITHER A STANDARD K[SUB]IC OR A J-INTEGRAL ANALYSIS WAS USED TO OBTAIN THE TOUGHNESS VALUE. AT ROOM TEMPERATURE, REGARDLESS OF ALLOY, ORIENTATION, OR MICROSTURECTURE, FRACTURE TOUGHNESS VALUES BETWEEN 15 AND 22 MPa m{sup 1/2} (14 AND 20 KSI IN{sup 1/2}) WERE MEASURED. THESE K[SUB]IC VALUES WERE CONSISTENT WITH MEASUREMENTS BY THE AUTHORS. INCREASING TEMPERATURE IMPROVES THE TOUGHNESS, DUE TO THE FACT THAT ONE TAKES ADVANTAGE OF THE DUCTIVE-BRITTLE TRANSITION BEHAVIOR OF MOLYBDENUM. AT 300 DEGREES C, THE FRACTURE TOUGHNESS OF RECRYSTALLIZED LCAC AND ARC-CAST TZM MOLYBDENUM WERE ALSO SIMILAR AT APPROXI MATELY 64 MPa m{sup 1/2} (58 KSI IN{sup 1/2}). IN THE STRESS-RELIEVED CONDITION, HOWEVER, THE TOUGHNESS OF ARC-CAST TZM (91 MPa m{sup 1/2}/83 KSI IN{sup 1/2}) WAS HIGHER THAN THAT OF THE LCAC MOLYBDENUM (74 MPa m{sup 1/2}/67 KSI IN{sup 1/2}).

For over 45 years, the United States has been trying to tame the energy source of the hydrogen bomb to produce electricity. Harnessing fusion, the nuclear reaction that powers the sun, requires confining and heating deuterium and tritium nuclei so that they will produce sustained, controlled nuclear energy. One path, called magnetic fusion energy (MFE), is to use very strong magnetic fields to confine a deuterium and tritium plasma while heating it to fusion temperatures.
