The variety of applications, databases, and information technologies makes it difficult to locate and retrieve information or applications that are otherwise openly available. The promise of the World Wide Web was that it was a paradigm for organizing and distributing information. Under this project, we looked at how we could more tightly couple the Web with the UNIX operating system for exchanging information, connecting programs and data, and facilitating collaboration between people in a more natural way. Ease of secure access and the ability to have electronic dialogues on specific questions will become increasingly important as the pressure Increases for scientists and analysts to rapidly access diverse information to make informed judgments and initiate new lines of Investigation.

All elements of the research triad in this country - universities, federal laboratories, and industrial labs - have spent a good part of the last decade in a very changeable and changing environment. In the area of partnerships with industry there have been a lot of experiments, such as the Advanced Technology Program (ATP), the Technology Reinvestment Program (TRP), and the Department of Energy`s (DOE) analog, the Technology Transfer Initiative (TM). We now have, at least in principle, gained enough experience with cross-sector partnerships to make some observations on what works and what doesn`t. My judgments are preliminary and driven by the idiosyncrasies of my own lab. I think the general themes at Livermore are reflected in other DOE national security labs and, at least to some extent, in other federal labs. Although we share some features in common with universities and industrial labs, I think the nature of our funding sources, and the way in which we are affected by global political factors such as the Cold War, pose a somewhat special set of circumstances for our institutions.

This report addresses Food and Agriculture provisions in the FY1997 Supplemental Appropriations Act.

This report examines the potential health effects of non radiological emissions to the air resulting from operations at the Savannah River Site (SRS). The scope of this study was limited to the 55 air contaminants for which the US Environmental Protection Agency (EPA) has quantified risk by determining unit risk factors (excess cancer risks) and/or reference concentrations (deleterious non cancer risks). Potential health impacts have been assessed in relation to the maximally exposed individual. This is a hypothetical person who resides for a lifetime at the SRS boundary. The most recent (1994) quality assured SRS emissions data available were used. Estimated maximum site boundary concentrations of the air contaminants were calculated using air dispersion modeling and 24-hour and annual averaging times. For the emissions studied, the excess cancer risk was found to be less than the generally accepted risk level of 1 in 100,000 and, in most cases, was less than 1 in 1,000,000. Deleterious non cancer effects were also found to be very unlikely.

We examined the progression of the Rayleigh-Taylor (RT) instability from an initial multimode perturbation. The RT experiments focused on the transition from the linear to non-linear regimes for perturbation growth at an embedded, or classical, interface. The multimode experiments have attempted to observe the process of bubble competition wherein neighboring structures either continue to rise or are washed downstream in the flow depending upon; their relative size. This competition is predicted to result in an inverse cascade at late times where progressively larger structures will begin to dominate the flow. Experiments to date have shown evidence of coupled modes arising, but have not yet accelerated the interface long enough to produce the several generations of coupling required for a true inverse cascade.

Lawrence Livermore National Laboratory (LLNL) has developed an all-particle Monte Carlo radiotherapy dose calculation code--PEREGRINE--for use in clinical radiation oncology. For PEREGRINE, we have assembled high-energy evaluated nuclear databases; created radiation source characterization and sampling algorithms; and simulated and characterized clinical beams for treatment with photons, neutrons and protons. Spectra are available for the Harper Hospital (Detroit, U.S.A.) Be(d,n) neutron therapy beam, the National Accelerator Centre (NAC, Faure, S.A.) Be(p,n) neutron therapy beam and many of the operating modes of the Loma Linda University Medical Center (LLUMC, Loma Linda, USA) proton treatment center. These beam descriptions are being used in PEREGRINE for Monte Carlo dose calculations on clinical configurations for comparisons to measurements. The methods of defining and sampling the beam phase space characterizations are discussed. We show calculations using these clinical beams compared to measurements in homogeneous water phantoms. The state of PEREGRINE's high energy neutron and proton transport database, PCSL, is reviewed and the remaining issues involving nuclear data needs for PEREGRINE are addressed.
