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.

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.

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.

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.

This issue brief analyzes six areas in which Federal policies to address the educational system's current needs are being fashioned (1) services for disadvantaged youth, (2) the financing of post-secondary education, ( 3 ) the level of Federal appropriations for education, ( 4 ) responses to adult illiteracy, (5) international economic competitiveness, and (6) the role of vocational education.

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 …
