[Letter from Bill McCarter to Carol Wyrick, July 15, 1996]

Photocopies of evaluations and comments for the National Museum of American Art, Smithsonian Institution: An Introduction to Latino Art and Culture, dated June 26 - 28, 1996. The evaluations are rating the quality of the workshop by answering the questions of material, information, topics and other objectives that the exhibit provided. In a letter to Carol Wyrick, July 15, 1996, Bill McCarter apologies for withholding the evaluations but NTIEVA wanted to record the general comments made about the Institute. Some of the comments read as written, "I enjoyed the workshop and learned a lot." "Those of us who teach the younger students found the drawing studies to be of little relevance to the level of production appreciated [by] our students." Other comments continue with the enthusiasm of the quality of materials and the presentations, as well as offer suggestions or provide concerns about the related subject.

Demonstration of innovative applicatiions of technology for cost reductions to the CT-121 FGD process (open access)

Demonstration of innovative applicatiions of technology for cost reductions to the CT-121 FGD process

The objective of this project is to demonstrate on a commercial scale several innovative applications of cost-reducing technology to the Chiyoda Thoroughbred-121 (CT-121) process. CT-121 is a second generation flue gas desulfurization (FGD) process which is considered by the Electric Power Research Institute (EPRI) and Southern Company Services (SCS) to be one of the most reliable and lowest cost FGD options for high-sulfur coal-fired utility boiler applications. Demonstrations of the innovative design approaches will further reduce the cost and provide a clear advantage to CT121 relative to competing technology.

Beam and viewing dump positioning inside TFTR for CTS alpha-particle diagnostics (open access)

Beam and viewing dump positioning inside TFTR for CTS alpha-particle diagnostics

A collective Thomson scattering (CTS) diagnostic system for localized measurement of energetic ions is being developed for TFTR. This system will use a 200KW, 56GHz gyrotron and a sensitive heterodyne receiver. In addition, a key element of this system will be beam and viewing dumps which are needed to minimize detection of stray gyrotron and ECE background radiation by the receiver system. It is the purpose of this study to determine the size and location of these dumps inside TFTR taking into account beam refraction and launch and receiver antenna optics scanning. The beam dump must cover all the area in the vacuum chamber where the beam is expected to impinge, and the viewing dump must cover all the areas within the direct line of sight of the receiver antenna. The beam launch system and the receiver antenna are to be placed nearly symmetrically above and below the midplane of the tokamak vacuum vessel, respectively. The beam dump is to be placed at the bottom inside of the vacuum vessel to absorb the gyrotron beam which will be launched from a top port. The viewing dump is expected to be placed symmetrically at the top inside of the vacuum vessel, …

Weld Penetration and Defect Control (open access)

Weld Penetration and Defect Control

Highly engineered designs increasingly require the use of improved materials and sophisticated manufacturing techniques. To obtain optimal performance from these engineered products, improved weld properties and joint reliability are a necessarily. This requirement for improved weld performance and reliability has led to the development of high-performance welding systems in which pre-programmed parameters are specified before any welding takes place. These automated systems however lack the ability to compensate for perturbations which arise during the welding process. Hence the need for systems which monitor and control the in-process status of the welding process. This report discusses work carried out on weld penetration indicators and the feasibility of using these indicators for on-line penetration control.

Molecular biological enhancement of coal biodesulfurization. [Rhodococcus] (open access)

Molecular biological enhancement of coal biodesulfurization. [Rhodococcus]

The objective of this project is to produce one or more microorganisms capable of removing the organic and inorganic sulfur in coal. The original specific technical objectives of the project were to: Clone and characterize the genes encoding the enzymes of the 4S'' pathway (sulfoxide/sulfone/sulfonate/sulfate) for release of organic sulfur from coal; Return multiple copies of genes to the original host to enhance the biodesulfurization activity of that organism; Transfer this pathway into a fast-growing chemolithotrophic bacterium; Conduct a batch-mode optimization/analysis of scale-up variables.

Studies of human mutation rates (open access)

Studies of human mutation rates

The three objectives of the program are: To isolate by the technique of two-dimensional polyacrylamide gel electrophoresis (2-D PAGE), proteins of special interest because of the relative mutability of the corresponding gene, establish the identity of the protein, and, for selected proteins, move to a characterization of the corresponding gene; To develop a more efficient approach, based on 2-D PAGE, for the detection of variants in DNA, with special reference to the identification of a variant in a child not present in either parent of the child (i.e., a mutation); and, To continue an effective interface with the genetic studies on the children of atomic bomb survivors in Japan, with reference to both the planning and implementation of new studies at the molecular level. For administrative purposes, the program is subdivided into four sections, each under the direction of one of the four co-PIs; the progress during the past year will be summarized in accordance with this sectional structure. 1 tab.

Possible explosive compounds in the Savannah River Site waste tank farm facilities (open access)

Possible explosive compounds in the Savannah River Site waste tank farm facilities

Based on a comparison of the known constituents in high-level nuclear waste stored at the Savannah River Site (SRS) and explosive compounds reported in the literature, only two classes of explosive compounds (metal NO{sub x} compounds and organic compounds) were identified as requiring further work to determine if they exist in the waste, and if so, in what quantities. Of the fourteen classes of explosive compounds identified as conceivably being present in tank farm operations, nine classes (metal fulminates, metal azides, halogen compounds, metal-amine complexes, nitrate/oxalate mixtures, metal oxalates, metal oxohalogenates, metal cyanides/cyanates, and peroxides) are not a hazard because these classes of compounds cannot be formed or accumulated in sufficient quantity, or they are not reactive at the conditions which exist in the tank farm facilities. Three of the classes (flammable gases, metal nitrides, and ammonia compounds and derivatives) are known to have the potential to build up to concentrations at which an observable reaction might occur. Controls have been in place for some time to limit the formation or control the concentration of these classes of compounds. A comprehensive list of conceivable explosive compounds is provided in Appendix 3.
