ELECTROPOLISHING (EP) IS AN IMPORTANT METAL FINISHING PROCESS WHICH IS USED WIDELY IN INDUSTRY ESPECIALLY IN THE CASES, WHERE MECHANICAL POLISHING IS NOT SUITABLE OR UNECONOMICAL E.G. IN CASE OF HARD METALS AND ALLOYS, THIN WALLED EASILY DEFORMABLE COMPONENTS, AND COMPLEX SHAPES, THE INTERIOR SURFACES OF THE COMPONENTS , SHARPENING TOOLS, SMOOTHING OF MACHINE PARTS EXPOSED TO FRICTION, REMOVAL OF …

THE MICROSPORIDIAN VAIRIMORPHA (NOSEMA) EPHESTIAE (MATTES) – (PROTOZOA, MICROSPORIDIA) WAS TESTED AGAINST THE RED PALM WEEVIL (RPW),RHYNCHOPHORUS FERRUGINEUS (F). THE PATHOGEN WAS ISOLATED FROM THE MEDITERRANEAN FLOUR MOTH LARVAE, EPHESTIA KUEHNIELLA ZELL , AND PROPAGATED SUCCESSFULLY ON THE SAME HOST OR ON THE EGYPTIAN COTTON LEAFWORM. THE PATHOGEN CAUSED LETHAL EFFECT TO RPW LARVAE ADULTS WHEN APPLIED AT 25 -100?106 …

BRASS CORE OF THE TAP HAS BEEN REMOVED COMPLETELY WITH ITS GASKET. IT HAS BEEN REPLACED WITH A STRONG RUBBER CORE FILLED INSIDE TAP CORE. A THIN COPPER WIRE IS INSERTED IN THE MIDDLE OF THIS RUBBER WHOSE END IS ATTACHED TO THE CLOSING BRASS WASHER(OVER WHICH THE RUBBER GASKET IS USUALLY PLACED). THE END OF THE BRASS CORE IS …

THIS AMENDMENTS AIMS TO REDUCE THE VOLUME OF POLLUTION COMES OUT OF BUSES AND TRUCKS EXHAUSTS TO INCREASE MOTORS EFFICIENCY IN ORDER TO EXPAND THE PERIOD OF RE-ADJUSTING THE MOTORS .THIS WILL LEAD TO REDUCING MAINTENANCE COST .CANCELING THE UPPER AND OUTSIDE EXHAUSTS FOR THE BUSES AND TRUCKS WILL IMPROVE THE APPEARANCE, REDUCE THE COSTS, LEAD TO PREVENT OR LESSENS …

THE ELECTRONIC CNG DISPENSER SYSTEM IS DESIGNED TO CONTROL AND MEASURE CNG QUANTITY DELIVERED TO VEHICLES WITH TEMPERATURE COMPENSATION TO ENSURE THAT VEHICLES ARE ALWAYS ACHIEVED COMPLETE FILL.IN ORDER TO MAKE THE UTILIZATION OF THE STATION COMPRESSOR AND BUFFER STORAGE MORE EFFICIENT, THE SYSTEM WILL OPERATE USING A THREE-STAGE “CASCADE” BUFFER SYSTEM. THE BUFFER STORAGE IS DIVIDED INTO THREE “BANKS”: …
