Computation of self-consistent 2-D MHD with neutral-beam and bootstrap currents in elongated plasmas
The observation of substantial current drive from neutral beam injection (NBI) in TFTR, JET and DIII-D has led to renewed interest in a steady state, non-inductively driven tokamak. The discovery of apparently considerable neoclassical (bootstrap) current in TFTR, makes a steady state device even more attractive since the bootstrap portion of the current could be obtained without additional power input. Motivated by these results, we have developed a code, ACCOME, which self-consistently computes the 2-D MHD equilibrium with the current driven by neutral beams, bootstrap and the electric field. In this paper we first describe some details of the code in the next section and in the subsequent section show some applications to DIII-D and to a possible ITER design.

[Letter from Dave McIntyre to Jack Davis, April 5, 1994]
Photocopy of a letter from Dave McIntyre, Visual Arts Facilitator for El Paso ISD, to Jack Davis, co-director of North Texas Institute for Educators on the Visual Arts. Iin regards to a presentation Davis, Nancy Reynolds and Jeff Young gave on Arts Advocacy in El Paso the previous week. The presentation made a positive impact on the faculty and the people present in attendance and have been motivation to act upon the inclusion of the program into their curriculum. McIntyre formally invites NTIEVA back to El Paso and present to the art specialists in the El Paso district and is looking forward to working with Davis and NTIEVA. Copied on the letter are Nancy Reynolds and Jeff Young.

[Letter From María Dolores Álvarez-Rodríguez to Jack Davis, April 5, 1993]
Photocopy of a letter from María Dolores Álvarez-Rodríguez, Department of Education, University of Granada, Spain, to Jack Davis, co-director of North Texas Institute for Educators on the Visual Arts. Rodriguez is a professor at Granada University, working on her Ph.D. on Art Education and is interested in DBAE, discipline-based art education. Having contacted the Getty Center for more information they re-addressed her to the North Texas Institute for Educators on the Visual Arts. Rodriguez hopes that Davis will be able to send her some information regarding the teacher training program and other subjects in its relation, along with the inquiry about outside observers to attend meetings / seminars if possible.

Literature review of the saturation state of seawater with respect to calcium carbonate and its possible significance for scale formation on OTEC heat exchangers
An investigation of available data on the saturation state of seawater with respect to calcium carbonate and its possible significance for scale formation on Ocean Thermal Energy Conversion (OTEC) heat exchangers has been carried out. Pertinent oceanographic data is lacking at or near potential OTEC sites for the calculation of the degree of saturation of seawater with respect to calcium carbonate. Consequently, only ''extrapolated'' saturation values can be used. These indicate that near surface seawater is probably supersaturated, with respect to the calcium carbonate phases calcite and aragonite, at all potential OTEC sites. The deep seawater that would be brought to the surface at the potential Atlantic Ocean sites is also likely to be supersaturated with respect to calcium carbonate. The deep seawater at the potential Pacific Ocean sites may be slightly undersaturated. The fact that OTEC heat exchangers will be operating in seawater, which is supersaturated with respect to calcium carbonate, means that if nucleation of calcite or aragonite occurs on the heat exchanger surfaces, significant growth rates of calcium carbonate scale may be expected. The potential for calcium carbonate nucleation is highest at cathodic metal surface locations, which are produced as the result of aluminum corrosion in seawater. …

Powerplant Productivity. Improvement Study: current practices in Illinois utilities towards powerplant productivity. Final report, Project 1, Task 1
Efforts of this task indicate that powerplant productivity is a complex issue that has to take into account economic factors, equipment limitations, and system-loading characteristics as well as external constraints such as regulatory requirements. Among the specific findings are: (1) utilities in Illinois use the industry-wide measures of performance such as capacity factor, availability factor, forced outage rates etc.; equivalent availability as a measure is not in common practice; (2) several unit performance statistics are collected on a routine basis such as the daily unit status, component outage data, monthly production figures etc.; (3) identifying major causes of lost productivity appears to be a relatively simple task, but finding economically and technically acceptable corrective actions are generally more difficult; (4) selection of improvement projects, as well as evaluating their future impacts, is mostly based on operating experience and engineering judgement, with no use of formal analytical/statistical models; (5) there generally is a group in every utility - typically called the power production department - with routine responsibilities for upkeep of unit productivity; and (6) recently the Commonwealth Edison Co. has developed a procedure for utilizing the Edison Electric Institute outage data base for analyzing productivity-related questions at nuclear plants; this …
