convective mhd oscillatory flow past a uniformly moving infinite vertical plate

the convective magnetohydrodynamic flow past a uniformly moving infinite vertical plate, with the magnetic field and the suction velocity applied normal to the plate has been analysed. presence of heat source or sink has also been considered. the findings are expected to throw light on some problems of defence applications in the areas of..

enlargement of the pindari dam

designs have been finalized and a contract recently awarded for the enlargement of pindari dam, a concrete faced rockfill dam (cfrd) originally constructed between 1966 and 1968 on the severn river in northern new south wales, australia. the dam will be heightened by 40.4 m to 85 m-high, resulting in an increase in storage capacity from 3..

screen and pad transfer decorating of molded plastic parts

silk screen printing, screen process printing, stencil printing, serigraphy, or mitography all describe a printing process in which ink is forced through a woven mesh in a selective manner so as to produce a controlled image, repeatedly. this first part of the paper describes the screen printing techniques applied to decoration of contain..

die trocknung von leiterplatten mittels uv-bestrahlung. $left bracket$ drying printed circuits with uv radiation $right bracket$

circuit boards are generally provided with solder resist and identification print. these are applied by silk-screening but in order to dry them more speedily and efficiently, the uv technique was devised. the high-energy, ultraviolet radiation is tuned to the resonance of the carbon double bonds in the lacquer and causes hardening within ..

use of waste wool for the removal of mercury from industrial effluents, particularly those from the chlor-alkali industry

waste wool samples, mainly dyed wool-synthetic blends discarded from wool manufacturing processes, have been examined for their ability to absorb mercury from aqueous solutions of mercury (ii) chloride. the amount of mercury sorbed paralleled the keratin protein (wool) content reaching more than 90 percent sorption from 100 ppm hg solutio..
