Abstract: A method for vacuum heat treating Nb, such as is used in superconducting radio frequency cavities, to engineer the interstitial oxygen profile with depth into the surface to conveniently optimize the low-temperature rf surface resistance of the material. An example application is heating of 1.3 GHz accelerating structures between 250-400° C. to achieve a very high quality factor of 5×1010 at 2.0 K. With data supplied by secondary ion mass spectrometry measurements, application of oxide decomposition and oxygen diffusion theory was applied to quantify previously unknown parameters crucial in achieving the oxygen alloy concentration profiles required to optimize the rf surface resistance. RF measurements of vacuum heat treated Nb superconducting radio frequency cavities confirmed the minimized surface resistance (higher Q0) previously expected only from 800° C. diffusive alloying with nitrogen.

Abstract: A system for installing a seal on a work piece includes a stretcher tool having a tapered end, an outer diameter opposite the tapered end, and an axial bore. A collar has an inner diameter greater than the outer diameter, and the collar is adapted to slide over the outer diameter to push the seal over the outer diameter. A method for installing a seal on a work piece includes placing the seal on a stretcher tool, wherein the stretcher tool has a tapered end, an outer diameter opposite the tapered end, and a stretcher axial bore. The method further includes sliding a collar over the tapered end and the outer diameter, engaging the collar against the seal, and sliding the collar over the outer diameter to push the seal into a first groove in the work piece.

Abstract: A multi-stage evaporative cooling system and method employing direct evaporative cooling at each stage. An exhaust fan is located between stages to expel warm air and partially depressurize the vapor space. An aspect of the present disclosure also describes the application of evaporative cooling to a pet shelter.

Abstract: The present invention provides uses of multi-nutrient supplements to rescue aberrant biochemical pathways and reduce birth defect caused by maternal diabetes. Choice of supplements is based on the ability of each supplement to correct the following hyperglycemia-associated abnormalities: increased reactive oxygen species generation, abnormal membrane phospholipid metabolism, and decreased glutathione synthesis.

Abstract: A seating arrangement for a motor vehicle includes a lower seat cushion for supporting a vehicle occupant. The seating arrangement further includes a floor pan.

Abstract: A narrow range of dinuclear spectral sensitizing dyes can be used in photothermographic silver halide emulsions without adversely affecting fog and speed levels with concentration variations.

Abstract: The addition of a class of compounds to a photothermographic emulsion reduces latent image fade.

Abstract: Photothermographic emulsions may be stabilized against latent image fade and/or may have their speed increased by the addition of diazepines and fused aromatic diazepines.

Abstract: Certain members of the class of odd-numbered methine arylidene dye bases are found to be of use in thermally-developable photosensitive compositions and thermally-developable photosensitive elements containing such agents. These compounds are acutance agents which are relatively stable against photo-bleaching but undergo thermochemical bleaching on heating in silver salt-containing thermally-developable photosensitive compositions.
