determination of the limiting sensitivity and specificity for the immunoassay of antigens and antibodies using ord's evanescent wave method. final rept. 1 feb 90-31 jan 93

the goal of this project, a rigorous side by side comparison of sensitivity of the 1992 version of evanescent wave (ew) technology with elisa, has been achieved. we conclude that sensitivity is the same for both systems when surface binding chemistries are equal during the second half of the effort we have focussed on-improving surface bi..

effect of intermittent cold exposure on the fiber-type composition of selected skeletal muscles in rats. final technical rept. mar-nov 90

we examined the effect of long-term intermittent cold exposure (ce) on the fiber-type composition of the predominantly type i soleus and the predominantly type iib extensor digitorum longus (edl) muscles of the rats. ce was accomplished by submerging the rats in shoulder-deep water, maintained at 20 = 0.5 deg c, for 1 h/d, 5 d/wk, for up ..

this memorandum details visits made to the bayside, l. i., laboratory of sylvania electric products company on august 11 and 13, 1953, to observe progress on production of flat plate fuel elements by powder metallurgy

surface preparation and characterization of a 400 (mu)m diameter fused silica optical fiber for direct optical initiation (doi) applications

studies were conducted to determine the effect of lapping and polishing variables on fiber optic surface finish, flatness, perpendicularity to axis, and subsurface characteristics. the studies were done with a fiber having a 400 (mu)m diameter fused silica core and a 440 (mu) outer diameter fused silica cladding used for doi (direct optic..

better ceramics through chemistry v. materials research society symposium proceedings held in san francisco, california on april 27 - may 1, 1992. volume 271

topics include: molecular routes to ceramic materials: new chemistry for the sol-gel process: acetone as a new condensation reagent; heterometallic aggregates as intermediates on the molecular routes to multicomponent oxides; further studies on aluminum oxoalkoxide clusters; studies on the formation of tin(iv) alkoxide compounds by sol-ge..

0.3 mm diameter flexible amperometric lactate probe. technical rept. oct 92-nov 93

a flexible lactate electrode was made of 400 plus or minus 100 7 micrometers diameter carbon fibers, epoxy embedded in a 0.3 mm diameter polyimide tubing. the electrode was modified by precipitating on it the relatively insoluble complex formed between 1100 kd partially n-ethylamine quaternized poly((vinylpyridine) os(bipyridine)2cl)cl (p..
