effects of chemical protective gloves and glove liners on manual dexterity. final technical rept. dec 88-jan 90

this study was conducted to determine the effects on manual dexterity performance of two thickness of butyl, chemical protective gloves, 0.64 mm and 0.36 mm, and of two types of cotton glove liners, a seam-stitched and a stingknit version. over seven working days, 12 male subjects performed three, fine-finger dexterity tests while bare-ha..

process for reinforced yarn with glass fiber core. patent

the invention discusses a unique process for producing torque-free or balanced yarns of staple fibers with glass filament cores. staple fiber roving is fed through a drafting system. glass filament is fed into the center of the staple fiber just prior to entering the front rolls of the drafting system. cotton fiber is the principle fiber ..

cumulus parameterization scheme designed for nested grid meso-(beta) scale models

a generalized cumulus parameterization based upon higher order turbulence closure has been incorporated into one dimensional simulations. the scheme consists of a level 2.5w turbulence closure scheme mated with a convective adjustment scheme. the convective adjustment scheme includes a gradient term which can be interpreted as either a su..

reverse osmosis water purification unit: efficacy of cartridge filters for removal of bacteria and protozoan cysts when ro elements are bypassed

two different filter combinations have been tested as candidate systems for bypassing the reverse osmosis membranes of the army's rowpu when treating fresh water: a spiral-wound cotton prefilter of 5.0 micrometers nominal pore size combined with either a melt-blown polypropylene depth filter or a pleated polypropylene filter of 3.0 microm..

reduction of hydrogen cyanide concentrations and acute inhalation toxicity from flexible polyurethane foam combustion products by the addition of copper compounds. part 4. effects of combustion conditions and scaling on the generation of hydrogen cyanide

two full-scale protocols (a && b) were tested to determine the efficacy of cuprous oxide (cu2o) in reducing the concentrations of hydrogen cyanide (hcn) from flexible polyurethane foams (fpu) when thermally decomposed under realistic room conditions. in each protocol a test, a fpu cushion (untreated or treated with 0.1 cu2o) was cut in ha..

replacement of coconut oils with unsaturated oils in recombined filled milk. final rept. apr 90-may 91

government owned, contractor operated milk plants are using coconut fat in the production of recombined filled milk at military bases abroad. consumer concerns regarding elevation of serum cholesterol by saturated fats has resulted in studies to replace coconut fat with less saturated vegetable fats. this research was conducted to formula..

gri/tgs mineral model level two report supplemental appendices topical report, august 1992

interpretation of wireline logs can be significantly improved by a quantitative knowledge of the rock mineralogy in the formation. the knowledge may be obtained from core analysis. alternatively, wireline well logs may be used to derive minerals from measurements of chemical elemental analysis logs. the elements must be combined to form m..

motionless michelson for high precision laser frequency measurements' the sigmameter

this method can be used to measure the frequency of a single mode tunable dye laser with an accuracy of a few mhz. the apparatus does not include any moving parts, it gives a direct visualisation of the wavenumber and is able to work as well in a cw as in a pulsed laser regime. on the other hand, it can be used, as a reference, to servoco..
