3 editions published between 1992 and 1993 in English and held by 0 WorldCat member libraries worldwide

This is the second annual report on the Hawaii Energy Strategy (HES) program which began on March 2, 1992, under a Cooperative Agreement (FCO3-92F19l68) with the United States Department of Energy (USDOE). The HES program is scheduled for completion by December 31, 1994. As outlined in the Statement of Joint Objectives. The purpose of the study is to develop an integrated State of Hawaii energy strategy, including an assessment of the State's fossil fuel reserve requirements and the most effective way to meet those needs, the availability and practicality of increasing the use of native energy resources, potential alternative fossil energy technologies such as coal gasification and potential energy efficiency measures which could lead to demand reduction. This work contributes to the (US)DOE mission, will reduce the State's vulnerability to energy supply disruptions and contributes to the public good

Particle pressures in fluidized beds( )

3 editions published between 1992 and 1993 in English and held by 0 WorldCat member libraries worldwide

This is an experimental project to make detailed measurements of the particle pressures generated in fluidized beds. The focus lies in two principle areas: (1) the particle pressure distribution around single bubbles rising in a two-dimensional gas-fluidized bed and (2) the particle pressures measured in liquid-fluidized beds. This first year has largely been to constructing the experiments The design of the particle pressure probe has been improved and tested. A two-dimensional gas-fluidized bed has been constructed in order to measure the particle pressure generated around injected bubbles. The probe is also being adapted to work in a liquid fluidized bed. Finally, a two-dimensional liquid fluidized bed is also under construction. Preliminary measurements show that the majority of the particle pressures are generated in the wake of a bubble. However, the particle pressures generated in the liquid bed appear to be extremely small. Finally, while not directly associated with the particle pressure studies, some NERSC supercomputer time was granted alongside this project. This is being used to make large scale computer simulation of the flow of granular materials in hoppers

Culturally relevant science : an approach to math science education for Hispanics( )

3 editions published in 1996 in English and held by 0 WorldCat member libraries worldwide

This report describes later stages of a program to develop culturally relevant science and math programs for Hispanic students. Part of this effort was follow-up with 17 teachers who participated in early stages of the program. Response was not very good. Included with the report is a first draft effort for curriculum materials which could be used as is in such a teaching effort. Several of the participating teachers were invited to a writing workshop, where lesson plans were drafted, and critiqued and following rework are listed in this publication. Further work needs to be completed and is ongoing
The perpendicular electron energy flux driven by magnetic fluctuations in the edge of TEXT-U( )

3 editions published between 1994 and 1995 in English and held by 0 WorldCat member libraries worldwide

The two different expressions for the radial particle flux [Lambda] found in the literature, as given by equations (2) and (4), are identical if the parallel electric field is small. The first expression is derivable in a fluid approach, whereas the second follows from the analysis of individual particle orbits. These expressions, without change, are also valid for an arbitrary axisymmetric magnetic geometry. In a situation where the parallel electric field is significant, the more accurate expression for the particle flux is in terms of the standard E x B velocity

Nuclear research with the electromagnetic probe. Progress report( )

4 editions published between 1988 and 1994 in English and held by 0 WorldCat member libraries worldwide

The project discussed in this progress report focusses on understanding the many facets and scales of strongly interacting systems using the electromagnetic probe. On one hand we are investigating the spin properties of the nucleon (proton and neutron) through its fundamental constituents (quarks and gluons). On the other hand we are studying the properties of nucleons in nuclei and the few-body systems. The E142 and the newly approved E143 experiments planned at the Stanford Linear Accelerator Center are designed to provide an answer to the mystery of the missing spin of the proton, while the new letter of intent submitted to SLAC, will investigate the so called Color transparency effect related to the prediction of PQCD for the (e, e(prime)p) quasielastic process in nuclei. Our research involvement at the Continuous Electron Beam Accelerator Facility focusses in Hall A. From the technical point of view we are building the Coemption polarimeter for the Hall A beam line. This device should allow a precise measurement of the electron beam polarization for several approved experiments. From the physics aspect of the project we plan to perform the transverse/longitudinal separation of the nuclear response at high momentum transfer in the quasielastic region, the photodisintegration of deuterium with the measurement of the recoil polarization of the proton and the electromagnetic form factor of few body systems experiment
[Magnetic thin film research] : Progress report year 2( )

1 edition published in 1996 in English and held by 0 WorldCat member libraries worldwide

The work in the past year has primarily involved four areas of magnetic thin films: amorphous rare earth-transition metal alloys, epitaxial CoPt₃ and Ni-Pt alloy thin films, amorphous rare earth doped Si (a new class of dilute magnetic semiconductor with large negative magnetoresistance which the authors have discovered), and exchange-coupled antiferromagnetic insulators. In the amorphous alloys, they made a systematic study of the effects of local anisotropy, macroscopic (up tack) anisotropy, and exchange constant on the fundamental (and practical) properties of these magnetic alloys, as originally described in the grant proposal. The work on the epitaxial Co-Pt (and more recently Ni-Pt) alloys was originally undertaken as a comparison study to the amorphous alloys. Crystalline Co-Pt alloys have many striking similarities to the amorphous rare earth-transition metal alloys: perpendicular magnetic anisotropy, magneto-optic activity, and a {Tc} (for CoPt₃) somewhat above room temperature. They have discovered that these alloys exhibit a remarkable new phenomena; a surface-induced miscibility gap in a material which is believed to be completely miscible in the bulk. The authors are currently in several collaborations to measure specific heat of magnetic thin films. They used the specific heat to study antiferromagnetic superlattices, specifically NiO, CoO and MgO in various combinations to allow separation of effects of finite layer thickness and exchange coupling on the magnetic ordering
Lattice gas hydrodynamics : Theory and simulations. Final report, [February 1, 1989--March 31, 1991]( )

4 editions published in 1993 in English and held by 0 WorldCat member libraries worldwide

The first successful application of a microscopic analogy to create a skeleton cellular automaton and analyze it with statistical mechanical tools, was the work of Frisch, Hasslacher and Pomeau on the Navier-Stokes equation in two and three dimensions. This has become a very large research area with lattice gas models and methods being used for both fundamental investigations into the foundations of statistical mechanics and a large number of diverse applications. This present research was devoted to enlarging the fundamental scope of lattice gas models and proved successful. Since the beginning of this proposal, cellular automata have been constructed for statistical mechanical models, fluids, diffusion and shock systems in fundamental investigations. In applied areas, there are now excellent lattice gas models for complex flows through porous media, chemical reaction and combustion dynamics, multiphase flow systems, and fluid mixtures with natural boundaries. With extended cellular fluid models, one can do problems with arbitrary pairwise potentials. Recently, these have been applied to such problems as non-newtonian or polymeric liquids and a mixture of immiscible fluids passing through fractal or spongelike media in two and three dimensions. This proposal has contributed to and enlarged the scope of this work

Combustion-related studies using weakly-bonded complexes( )

3 editions published between 1992 and 1993 in English and held by 0 WorldCat member libraries worldwide

This work is concerned with microscopic-level phenomena of importance in combustion. Weakly bonded adducts formed in supersonic expansions are investigated spectroscopically and used to limit the angles and impact parameters of biomolecular encounters. Also examined are species in which a free radical such as oxygen is bonded to a stable molecule in a shallow well outside the reaction barrier. These species can be used for several studies such as those involving photoinitiated reactions. The main experimental approach uses tunable diode laser absorption spectroscopy to monitor and characterize in detail the complexes of interest, and laser photoinitiation and LIF/MPI detection to examine biomolecular processes in which the adducts are used as precursors. In the first phase of this research, geometries and other molecular properties are being determined from vibrational-rotational spectra. In the second phase, these complexes will be used as precursors to study photoinitiated reactions in precursor geometry limited environments
