fabrication, preirradiation characterization, and irradiation history for westinghouse br-3 rods. task 3. high burnup effects program

this report documents the fabrication and characterization for 3 westinghouse-design fuel rods supplied to the high burnup effects program, task 3. fuel rods being supplied to the high burnup effects program were initially designed and characterized for a westinghouse ramp program. the rods were specifically intended for preirradiation in..

surface modification of high-strength reinforcing fibers by plasma treatment. final report. progress rept

allied-signal inc., kansas city division, has, for several years, used plasma treatments to dry, activate, and clean polymeric surfaces to provide enhanced adhesive bonding. work in this area generated positive expectations regarding the plasma treatment of fibers. gas plasma treatment of fibers, prior to impregnation with epoxy resin, wa..

integration of rapid prototyping into design and manufacturing

the introduction of rapid prototyping machines into the market place promises to revolutionize the process of producing prototype parts with production-like quality. in the age of concurrent engineering and agile manufacturing, it is necessary to exploit applicable new technologies as soon as they become available. the driving force behin..

surface passivation of high-purity germanium gamma-ray detector

the experimental work consists of two parts. the first involves fabrication of hyper-pure germanium gamma ray detectors using standard surface treatment, chemical etchings and containment in a suitable cryostat. then, after cooling the detectors to 77 k, (gamma) -ray emissions from radioisotopes are resolved, resolution, depletion depth, ..

laser materials: radiation damage. (latest citations from the ntis database). published search

the bibliography contains citations concerning laser beam damage to laser materials, including optical glass, mirrors, optical coatings, dielectrics, semiconductors, and alkali metal halides. the damage mechanisms are explored for various types of laser fabrication and preparation of the materials and the resulting degradation or damage t..

textiles with surgical applications. (latest citations from world textile abstracts). published search

the bibliography contains citations concerning the manufacture of woven and nonwoven textiles for surgical applications. the manufacture of suture material, the chemical composition of bioabsorbable coatings, and the packaging of sutures are detailed topics also include the manufacture of surgical dressings, gowns, towels, drapes, and mas..

investigation of electrical breakdown in vacuum. final report progress rept

the program objectives are focused on increasing the voltage applied across an electron beam diode. two objectives were pursued during the program. the first was to increase the total voltage applied to an electron gun anode--cathode (a-k) structure by suppressing electron emission from regions other than the electron source. the second o..

modification of polymer surfaces and the fabrication of submicron-scale functionalized structures by deep-uv and electron beam lithography. technical rept. mar 92-jun 93

we present a general technique to modify polymer surfaces using n-hydroxysuccinimide (nhs) funtionalized perfluorophenyl azides (pfpas). thin polystyrene films are spin-coated with a solution containing the nhs pfpa ester and are either uv photolyzed with a dosage of 10 mj sq cm or exposed with a 15 kv electron beam with a dosage between ..

electrical conductivity as a test for the integrity of latex gloves

surgical latex gloves have been used to protect patients against bacterial infections introduced by health-care workers. as a result of the acquired immune deficiency syndrome (aids) epidemic, the concern has shifted, with more emphasis on the protection of the health-care worker from the patient. these gloves often have defects, holes, w..

subacute intramuscular toxicity of the acetylcholinesterase reactivating agent hi-6 in rats and dogs. reprint: subacute intramuscular toxicity of the acetylcholinesterase reactivating agent hi-6 in rats and dogs

studies herein describe the toxicity of hi-6 in sprague-dawley rats and beagle dogs following i.m. injection for 14 days. dose levels were 0, 50, 150, and 450 mg/kg/day for 10 rats/sex/dose and 0, 35, 70, and 140 mg/kg/day for 4 dogs/sex/dose. three rats at the high dose, 2 males and 1 female, died prior to scheduled sacrifice reduced wei..
