Amorphous steel slag was blended with different concentrations of waste glass (20, 40, 50, 60, 70 wt.%) and SiC to obtain a composite. According to Hot Stage Microscopy images, slag-glass composite contractions started at 1050 ºC. scanning electron microscope micrographs of slag-SiC (foaming agent) composite revealed tunnel-like porosities of 500 to 1000 microns. Gaseous products of carbide dec...
The microstructure and properties of a silicon coating on titanium nickelide substrate were studied to assess the possibility using such improve biocompatibility medical implants. with thickness 4.0±0.5 microns was applied TiNi molecular beam epitaxy unit. had submicrocrystalline structure crystallite size 0.1...0.2 microns, developed surface, high crack resistance.
ABSTRACT A total of 2530 persons(1009 from Town and 1521 from suburban villages were selected randomly and examined by formalin ether concentration method . The overall prevalence of infection was (73.68%). The most common helminths were Ascaris lumbricoides (23.68%), Trichuris trichiura (11.26%) ,Hymenolepis nana (8.22%), and the most common pathogenic intestinal protozoa was Giardia lamblia...
Overall corneal hydration control expressed as the percent recovery per hour (PRPH) can be assessed with an exponential model that uses data derived from two kinds of corneal thickness measurements; one from monitoring recovery after inducing corneal swelling, and the other from measurements made after the eye has been open long enough to reach its open-eye steady-state (OESS) corneal thickness...
