Proton microprobe analysis of zinc in skeletal tissues. [Proton induced x-ray emission analysis]

Description: A proton microprobe with windowless exit port was used to study zinc distributions in various types of skeletal tissues. The use of an external beam facilitated positioning of the targets for examination of particular points of interest. The proton microprobe is uniquely suited to this work since it combines high sensitivity for zinc determinations in thick samples with good spatial resolution. Measurements on rat and rabbit Achilles tendon showed a significant increase in zinc concentrations a… more

Preliminary results on nu/sub. mu. / + e/sup -/. -->. nu/sub. mu. / + e/sup -/

Description: We present here preliminary results on a recent experiment on nu/sub ..mu../ - e/sup -/ elastic scattering. A brief review of the Glashow-Salam-Weinberg theory is given, indicating how the measurement of the total cross section gives rise to an ambiguous solution for sin/sup 2/ THETA/sub w/, and showing how the differential cross section can be used to resolve the ambiguity. The experimental configuration and the extraction of the signal are described. The data are compared with those from our … more

Theoretical high energy physics. [Annual report], May 1, 1992--April 30, 1993

Description: Brief reports are given on the work of several professors. The following areas are included: quantum chromodynamics calculations using numerical lattice gauge theory and a high-speed parallel computer; the ``spin wave`` description of bosonic particles moving on a lattice with same-site exclusion; a high-temperature expansion to 13th order for the O(4)-symmetric {phi}{sup 4} model on a four-dimensional F{sub 4} lattice; spin waves and lattice bosons; superconductivity of C{sub 60}; meson-meson … more

[Ion temperature gradient instability and transport: Progress report]

Description: Anomalous ion thermal conductivity remains in open physics issue for the present generation of high temperature Tokamaks. It is now believed to be due to the Ion Temperature Gradient (ITG or n{sub i}) instability. The production and identification of this instability is being studied in the simpler and experimentally convenient configuration of the steady state Columbia Linear Machine (CLM). The slab branch of this instability has been produced (by two different heating methods), identified and… more

High beta and confinement studies on TFTR. Progress report, 15 April 1993--14 April 1994

Description: Our work can be divided into two distinct parts: (1) deuterium plasma studies of the extension of our previous work on second stability region access and the observation of high-n ballooning and (2) deuterium-tritium plasma experimental planning and execution. Each of these is summarized in this report.

Surfactant loss control in chemical flooding spectroscopic and calorimetric study of adsorption and precipitation on reservoir minerals. Annual report, September 30, 1993--September 30, 1994

Description: The aim of this project is to elucidate the mechanisms underlying adsorption and surface precipitation of flooding surfactants on reservoir minerals. Effect of surfactant structure, surfactant combinations, other inorganic and polymeric species is being studied. A multi-pronged approach consisting of micro and nano spectroscopy, microcalorimetry, electrokinetics, surface tension and wettability is used to achieve the goals. The results of this study should help in controlling surfactant loss in… more

Deuterons and flow: At intermediate AGS energies

Description: A quantitative model, based on hadronic physics and Monte Carlo cascading is applied to heavy ion collisions at BNL-AGS and BEVALAC energies. The model was found to be in excellent agreement with particle spectra where data previously existed, for Si beams, and was able to successfully predict the spectra where data was initially absent, for Au beams. For Si + Au collisions baryon densities of three or four times the normal nuclear matter density ({rho}{sub 0}) are seen in the theory, while for… more

Human genetic marker for resistance to radiations and chemicals. 1998 annual progress report

Description: 'The broad objective of the project is to understand the molecular basis for the response of cells to radiations and chemicals, with the pragmatic goal of being able to identify human subpopulations that are exceptionally sensitive to DNA damaging agents. The project focuses on HRAD9, a human orthologue of the fission yeast Schizosaccharomyces pombe gene rad9. S. pombe rad9::ura4+ mutant cells are highly sensitive to ionizing radiation, UV and many chemicals, such as the DNA synthesis inhibitor… more

An inverse free electron laser accelerator: Experiment and theoretical interpretation

Description: Experimental and numerical studies of the Inverse Free Electron Laser using a GW-level 10.6 {mu}m CO{sub 2} laser have been carried out at Brookhaven`s Accelerator Test Facility. An energy gain of 2.5 % ({Delta}E/E) on a 40 MeV electron beam has been observed E which compares well with theory. The effects on IFEL acceleration with respect to the variation of the laser electric field, the input electron beam energy, and the wiggler magnetic field strength were studied, and show the importance of… more
