Radar Guns and Laser radar Guns


This is the age of speed. We can see people zipping down the highways at unimaginable speed. Long before the invention of radar guns in 1970's and laser speed guns in 1990's the police had a very tedious job in detecting those vehicles which where driven at over speed. The radar gun emits microwaves and works on the principle of radar where as the laser gun emits infrared rays and gives more accurate readings than the radar gun. The invention of the radar guns and the laser guns have proved to be a great ble ....etc

ABSTRACT


Hot isostatic processing (HIP) is the latest method to produce open porous materials, such as ceramics or metals. In this review paper, features and applications of HIPed porous materials are described. Sintering behavior under high pressure gas is also discussed in order to understand how porous materials are obtained by this method. HIPed porous materials have higher open porosity, higher mechanical strength, narrower pore size distribution and higher fluid permeabili ....etc

The new non-lethal weapon using the world's hottest chili. Measuring more than 1,000,000 Scoville units, the bhut jolokia. The chili weapon, a tear gas-like hand grenade stuffed with bhut(ghost) jolokia chilli peppers to immobilize rioters and terrorists without killing them and can able to immobilize suspects and force terrorists out of hiding. The active ingredient in chillis is Oleoresin Capsicum (OC), a complex mixture of organic compounds. Aficionados rate the hotness of chills using the Scoville scale, which measures the amount of dilu ....etc

Abstract
Hot machining is the process which is used for easy machining and to eliminate the problems of low cutting speeds, feeds and heavy loads on the machine bearings. This problem arises when machining process is being done on the new and tough materials. The basic principle behind this process is the surface of the work piece which is to be machined is to be pre heated to a temperature below the re-crystallization temperature. By this heating the shear forces gets reduces and mach ....etc
