This issue brief will discuss issues dealing with military manpower policy and the AIDS virus, including the level of the AIDS infection or HIV infection rates in the military; efforts to control the spread of AIDS to and among military personnel; and AIDS in the context of military personnel stationed overseas.

Under provisions of the Surplus Facilities Management Program (SFMP), the US Department of Energy, Chicago Operations Office, proposes to provide funding for Surveillance and Maintenance (S & M) and subsequent Decontamination and Decommissioning (D & D) of fifteen facilities and associated premises belonging to Battelle Columbus Division. The fifteen facilities are contaminated as a result of nuclear research and development activities conducted over a period of approximately 43 years for DOE and its predecessor agencies--the Energy Research and Development Administration (ERDA), the Atomic Energy Commission (AEC) and the Manhattan Engineer District (MED). The proposed action includes continuation of ongoing S & M as well as a D & D of the facilities. The S & M activities include a continued environmental monitoring program to maintain assurance that radioactive contamination has not escaped to the surrounding environment; regularly scheduled inspection and maintenance of health, safety, and radiation protection equipment and instrumentation; a program of health physics surveillance monitoring, personnel dosimetry, and equipment and instrumentation maintenance and calibration; and emergency planning, training, and drills. The so- called dismantlement D & D mode is the proposed alternative for D & D of these facilities. For the facilities in question this will generally involve …

LAXRIS (large area x-ray imaging spectrometer) is an experimental, balloon-borne, hard x-ray telescope that consists of a coaligned array of x-ray imaging spectrometer modules capable of obtaining high angular resolution (1--3 arcminutes) with moderate energy resolution in the 20- to 300-keV region. Each spectrometer module consists of a CsI(Na) crystal coupled to a position-sensitive phototube with a crossed-wire, resistive readout. Imaging is provided by a coded aperture mask with a 4-m focal length. The high angular resolution is coupled with rather large area (/approximately/800 cm/sup 2/) to provide good sensitivity. Results are presented on performance and overall design. Sensitivity estimates are derived from a Monte-Carlo code developed to model the LAXRIS response to background encountered at balloon altitudes. We discuss a variety of observations made feasible by high angular resolution. For instance, spatially resolving the nonthermal x-ray emission from clusters of galaxies is suggested as an ideal program for LAXRIS. 15 refs., 5 figs.

In the case of a gross argon spill from the DO detector, the liquid argon is caught in three plenums. These plenums are to be connected by bellows to make a horizontal trough open at one end for removing the argon. The design of these bellows is dependent on the maximum argon load they must carry. Bellows to connect the three argon-catching plenums in the DO detector must be able to carry at least 92 lbs of argon when closed and 231 lbs when open, plus the load due to argon in the convolutions. Examples of such loads and the method for their calculations are contained in the Discussion. It should be noted that a set of assumptions was used in these calculations. First, we considered a uniform channel and uniform flow. Second, we used a value for Manning's n meant for a similar, but not exactly the same, case. Finally, we were forced to define an average depth, d, to be used to state the hydraulic radius, R, and area of flow, A. These facts may warrant consideration in future calculations.

We review our methodologies in the design and analysis of soft x-ray laser experiments. We convolve large-scale 2-D hydro code output with detailed atomic data bases in a kinetics code with 1-D or 2-D line transfer. The time and space dependent level population data is then post processed further with a beam transport code, including refraction, to predict actual experimental results. While mysteries do remain, we present many examples that show how this complex modeling procedure is crucial in explaining experimental results. 23 refs., 8 figs., 1 tab.

Recent results on the total cross section, real-to-imaginary ratio of the forward scattering amplitude, and the slope parameter are discussed. The ability of future Tevatron data to distinguish between alternative explanations of the large value of /rho/ measured by UA-4 is emphasized. 8 refs., 1 tab.

This research project involves the design, synthesis and study of molecules which mimic many of the important aspects of photosynthetic electron and energy transfer. The knowledge gained from the study of synthetic model systems which abstract features of the natural photosynthetic apparatus can be used to design artificial photosynthetic systems which employ the basic physics and chemistry of photosynthesis to help meet mankind's energy needs. More specifically, the proposed models are designed to mimic the following aspects of natural photosynthetic multistep electron transfer: electron donation from a tetrapyrrole excited singlet state, electron transfer between tetrapyrroles, electron transfer from tetrapyrroles to quinones, and electron transfer between quinones with different redox properties.

The present study indicates that the B2 ..beta..-phase in quenched Ni/sub 62.5/Al/sub 37.5/ is distorted by displacement waves involving a planar shufflin of atoms resembling the final 7R martensite structure and with wavelenghts of the order of 1.3 nm. The appearance of a <110><110> type modulation with the indicated periodicity corresponds well with recent inelastic neutron scattering results which reveal nonlinear behavior in the TA<110> phonon dispersion curve around the same wavelengths indicating a partial lattice softening for such waves. In bulk material all six equivalent wave-vectors are equally present. These distortional modulations are configured in some form of three-dimensional assembly. Following the interpretation given above, it can be concluded that a one-dimensional domain structure along one of six <110> directions may exist. However, the beating of six displacement waves with apparently uncorrelated phase and wavelengths rules out the existence of a ''conventional'' three-dimensional domain structure. For this reason it is uncertain whether much more information can be gained from such image simulations. There are now numerous indications that the underlying structure to the tweed contrast in this alloy is a precursor effect of the martensitic transformation. However, a detailed description of the effective correlation between the distorted parent phase …

Precision spectroscopy of solar plasmas has historically been the goad for advances in calculating the atomic physics and dynamics of highly ionized atoms. Recent efforts to understand the laboratory plasmas associated with magnetic and inertial confinement fusion, and with X-ray laser research, have played a similar role. Developments spurred by laboratory plasma research are applicable to the modeling of high-resolution spectra from both solar and cosmic X-ray sources, such as the photoionized plasmas associated with accretion disks. Three of these developments in large scale atomic modeling are reviewed: a new method for calculating large arrays of collisional excitation rates, a sum rule based method for extending collisional-radiative models and modeling the effects of autoionizing resonances, and a detailed level accounting calculation of resonant excitation rates in FeXVII. 21 refs., 5 figs., 2 tabs.

The usefulness of various kinds of coatings to the die casting program has been studied. This work includes heat transfer and fluid flow calculations, as well as experimental work, to examine the feasibility and characteristics of various types of coatings. Calculations include the effect of surface roughness on fluid flow, conductance as a function of coating thickness, conductivity as a function of coating porosity, and solidification and possible remelting of microspheres of metal. In each case, the model is described and the results are presented. Experimental work involved evaluating the relative insulating value of various coatings and an analysis of commercial flame-sprayed coatings, low-density coatings, and release coatings. In each case, description of the experimental arrangement is given and the results are described. 5 refs., 28 figs., 6 tabs.
