A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO provided information on the interactions between Social Security and private pensions, focusing on the: (1) primary linkages between Social Security and private pensions and the way they interact to provide retirement income for workers and families; (2) effects of traditional Social Security reforms on the structure of employer-sponsored pension plans through changes in the costs and incentives faced by employers and workers; and (3) effects of nontraditional reforms, such as individual accounts, on the structure of the private pension system."

The objective of this calculation is to strengthen the existing trench cover plates of the Electrical Switchgear Building (BLDG 5010) of the Exploratory Studies Facility. A remodeling effort will change the portion of the facility that has the trenches for electrical cables to a craft/shop area. The users of the building will be using a forklift in this area (Clark CGP 30 forklift with a capacity of 3 tons). The trench covers require strengthening to support the wheel loads from the forklift. The output of this calculation will be sketches revising the floor plate details of DWG YMP-025-1-7007-ST103, Rev 02. (Details 4 and 5).

The Sudbury Neutrino Observatory (SNO) has been collecting data since November 1999. The study of whether or not the D{sub 2}O circulation affects the data is an important part of understanding how the SNO detector behaves. This report looks at several characteristics of the data to determine to what extent the D{sub 2}O circulation affects the data. We found that there is no evidence for any dependence of event rates in the cleaned data sets on the state of D{sub 2}O circulation.

Understanding high pressure behavior materials is necessary in order to address the physical processes associated with hypervelocity impact events related to space science applications including orbital debris impact and impact lethality. Until recently the highest-pressure states in materials have been achieved from impact loading techniques from two-stage light gas guns with velocity limitations of approximately 81cm/s. In this paper, techniques that are being developed and implemented to obtain the needed shock loading parameters (Hugoniot states) for material characterization studies, namely shock velocity and particle velocity, will be described at impact velocities up to 11 kds. The determination of equation-of-state (EOS) and thermodynamic states of materials in the regimes of extreme high pressures is now attainable utilizing the three-stage launcher. What is new in this report is that these techniques are being implemented for use at engagement velocities never before attained utilizing two-stage light-gas gun technology. The design and test methodologies used to determine Hugoniot states are described in this paper.

This project demonstrated that treated drill cuttings derived from oil and gas operations could be used as source material for rebuilding eroding wetlands in Louisiana. Planning to supply a restoration site, drill a source well, and provide part of the funding. Scientists from southeastern Louisiana University's (SLU) Wetland Biology Department were contracted to conduct the proposed field research and to perform mesocosm studies on the SLU campus. Plans were to use and abandoned open water drill slip as a restoration site. Dredged material was to be used to create berms to form an isolated cell that would then be filled with a blend of dredged material and drill cuttings. Three elevations were used to test the substrates ability to support various alternative types of marsh vegetation, i.e., submergent, emergent, and upland. The drill cuttings were not raw cuttings, but were treated by either a dewatering process (performed by Cameron, Inc.) or by a stabilization process to encapsulate undesirable constituents (performed by SWACO, Division of Smith International).

Correspondence issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO provided information on the Bureau of Indian Affairs' (BIA) use of federal Highway Trust Fund (HTF) money for Indian reservation roads, focusing on: (1) what percentage of fiscal years 1999 and 1998 HTF contract authority available to BIA was obligated for: (a) management costs directly related to specific projects within a program for construction, repair, and improvement of roads; and (b) program management and oversight costs not directly related to specific projects; (2) whether BIA spent more than 6 percent of the contract authority allocated to its Midwest and Western Regional Offices on non-project-related program management costs for those offices; (3) whether the annual 6 percent statutory limitation on the use of HTF contract authority for road program management costs applies only to non-project-related management costs; and (4) whether the project-related costs that BIA bears for individual tribes should be paid from HTF contract authority or from BIA's annual appropriations for managing Indian programs or construction."

Symmetric multiprocessor (SMP) clusters have become the prevalent computing platforms for large-scale scientific computation in recent years mainly due to their good scalability. In fact, many parallel machines being used at supercomputing centers and national laboratories are of this type. It is critical and often very difficult on such large-scale parallel computers to efficiently manage a stream of jobs, whose requirement for resources and computing time greatly varies. Understanding the characteristics of workload imposed on a target environment plays a crucial role in managing system resources and developing an efficient resource management scheme. A parallel workload is analyzed typically by studying the traces from actual production parallel machines. The study of the workload traces not only provides the system designers with insight on how to design good processor allocation and job scheduling policies for efficient resource management, but also helps system administrators monitor and fine-tune the resource management strategies and algorithms. Furthermore, the workload traces are a valuable resource for those who conduct performance studies through either simulation or analytical modeling. The workload traces can be directly fed to a trace-driven simulator in a more realistic and specific simulation experiments. Alternatively, one can obtain certain parameters that characterize the workload …

The authors use scanning probe microscopy to actuate and characterize the nanoscale mechanochromism of polydiacetylene monolayer on atomically-flat silicon oxide substrates. They find explicit evidence that the irreversible blue-to-red transformation is caused by shear forces exerted normal to the polydiacetylene polymer backbone. The anisotropic probe-induced transformation is characterized by a significant change in the tilt orientation of the side chains with respect to the surface normal. They also describe a new technique, based on shear force microscopy, that allows them to image friction anisotropy of polydiacetylene monolayer independent of scan direction. Finally, they discuss preliminary molecular mechanics modeling and electronic structure calculations that allow them to understand the correlation of mechanochromism with bond-angle changes in the conjugated polymer backbone.

The ''National Ignition Facility (NIF) Justification of Mission Need'', which was approved by the Secretary of Energy in January 1993, defines the mission of the National Inertial Confinement Fusion (ICF) Program and discusses the specific mission of the NIF Project. The NIF experimental capability will allow nuclear-weapons scientists to assess stockpile problems, verify computational tools, test for nuclear-weapons effects, and increase their understanding of weapons physics. The three weapons laboratory directors and the National Nuclear Security Administration (NNSA) Deputy Administrator for Defense Programs have reviewed the role of the NIT; in Stockpile Stewardship in a joint letter. Along with the Accelerated Strategic Computing Initiative numerical simulations and other aboveground experimental facilities, the NIF will provide critical data that will allow the United States to maintain its technical capabilities in nuclear weapons in the absence of underground testing. As a secondary objective, the NIF will advance our understanding of ICF and help to assess its potential as an energy source. Achieving fusion ignition in the NIF will advance both defense and energy objectives. In affirming the Project's Critical Decision 2,* ''Approval of New Start'', the Secretary of Energy verified the mission need and emphasized that the NIF has the potential to …
