Contract Management: Excess Payments and Underpayments Continue to Be a Problem at DOD

Description: A letter report issued by the General Accounting Office with an abstract that begins "GAO reviewed the amount of excess payments and underpayments made by the Department of Defense (DOD) to its contractors during fiscal year 1999. The Defense Finance and Accounting Service (DFAS)--Columbus Center, Ohio reports that contractors repaid $670 million in fiscal year 1999 and closer to a billion dollars--$901 million--in fiscal year 2000. The higher amount for fiscal year 2000 reflects the inclusion … more

Degradation and Failure Characteristics of NPP Containment Protective Coating Systems

Description: A research program to investigate the performance and potential for debris formation of Service Level I coating systems used in nuclear power plant containment is being performed at the Savannah River Technology Center. The research activities are aligned to address phenomena important to cause coating disbondment as identified by the Industry Coatings Expert Panel. The period of interest for performance covers the time from application of the coating through 40 years of service, followed by a … more

New Strategies for Designing Inexpensive but Selective Bioadsorbants for Environmental Pollutants: Selection of specific Ligands and Their Cell Surface Expression

Description: The Broad, long term objective of the research plan is to develop exquisitely selective polypeptide metal chelators for the remediation of aqueous systems. A variety of polypeptide chelators will be developed and optimized ranging from antibodies to small peptides. Then, through unique molecular engineering approaches developed in our laboratories, the polypeptide chelators will be anchored directly on the surface of the cells that produce them. Thus, instead of using isolated biomolecules we w… more

Carbon Flux to the Atmosphere from Land-Use Changes: 1850 to 1990

Description: The database documented in this numeric data package, a revision to a database originally published by the Carbon Dioxide Information Analysis Center (CDIAC) in 1995, consists of annual estimates, from 1850 through 1990, of the net flux of carbon between terrestrial ecosystems and the atmosphere resulting from deliberate changes in land cover and land use, especially forest clearing for agriculture and the harvest of wood for wood products or energy. The data are provided on a year-by-year basi… more

Causes of Indoor Air Quality Problems in Schools: Summary of Scientific Research

Description: In the modern urban setting, most individuals spend about 80% of their time indoors and are therefore exposed to the indoor environment to a much greater extent than to the outdoors (Lebowitz 1992). Concomitant with this increased habitation in urban buildings, there have been numerous reports of adverse health effects related to indoor air quality (IAQ) (sick buildings). Most of these buildings were built in the last two decades and were constructed to be energy-efficient. The quality of air i… more

Characterization of Prototype Superconducting Magnetic Quadrupolesfor the High Current Transport Experiment

Description: Later phases of the High Current Transport Experiment (HCX) at LBNL will employ superconducting magnetic quadrupole lenses to focus an intense, heavy-ion beam over approximately 50 lattice periods (100 quadrupoles). Here they present a characterization of a baseline quadrupole design suitable for transporting a single, low-energy ({approx} 2 MeV), high-current ({approx} 800 mA) heavy-ion (K{sup +}) beam that will be provided from an existing injector and beam matching section. For optimal perfo… more

Injection Molding of Plastics from Agricultural Materials

Description: The objective of this research was to conduct a systematic study to relate injection molding parameters to properties of blends of starch and synthetic polymer. From this study, we wished to develop a thorough understanding of the injection molding process and gain significant insight into designing molds and aiding in developing products cheaply and efficiently.

3(omega) Damage: Growth Mitigation

Description: The design of high power UV laser systems is limited to a large extent by the laser-initiated damage performance of transmissive fused silica optical components. The 3{omega} (i.e., the third harmonic of the primary laser frequency) damage growth mitigation LDRD effort focused on understanding and reducing the rapid growth of laser-initiated surface damage on fused silica optics. Laser-initiated damage can be discussed in terms of two key issues: damage initiated at some type of precursor and r… more

Evaluation of P/M Ring Gear Using Computed Tomography and Ultrasonic Testing

Description: Ultrasonic (UT) and computed tomography (CT) evaluation of a P/M ring gear was performed at LLNL to characterize the gear and to determine the relative sensitivity of the two techniques to defects of interest. The features of concern lie at the root of the teeth and in layers along the sides of the teeth. These layers can be detected using metalography but success depends on chance and the number of sections polished. Much of the current focus is on improving the sensitivity of the CT scan and … more
