Industries having the most mergers were primary metals‚ petroleum products‚ food products‚ chemicals‚ and transportations equipment. Many prominent corporations were born during this merger period namely General Motors‚ IBM‚ John Deere‚ and Union Carbide. In 1914‚ the Clayton Act was passed to reinforce the antimonopoly provisions of the Sherman Act. The antitrust environment‚ by and large‚ was more stringent

When a doped semiconductor contains excess holes it is called "p-type"‚ and when it contains excess free electrons it is known as "n-type". Germanium‚ gallium arsenide‚ and silicon carbide are common dopants. A pure semiconductor is often called an “intrinsic” semiconductor. The electronic properties and the conductivity of a

limitation‚ however‚ is that EDM only works with materials that are electrically conductive. EDM can cut small or odd-shaped angles‚ intricate contours or cavities in extremely hard steel and exotic metals such as iconel‚ hastelloy‚ kovar‚ titanium and carbide. Sometimes referred to as spark eroding or spark machining‚ EDM is a method of removing material by a series of rapidly recurring electric arcing discharges between an electrode (the cutting tool) and the work piece‚ in the presence of an energetic

INTRODUCTION Surface modification is a miraculous application of Electric Discharge Machining (EDM). It can modify the conductive material surface by both removing material from the surface and depositing material on the surface. It can remove or deposit material from the work surface through controlled electrical sparks by the process of melting and evaporation. The controlled sparks erode material from the work and tool surface within very short intervals of time. Study of surface morphology widens

The magnitude of the environmental and human devastation resulting from the Bhopal disaster confronted Union Carbide with a challenge that severely tested the mettle of its crisis communication expertise. Although two decades have elapsed since the disaster‚ Bhopal is still evoked as an example of “what not to do” in the case of a crisis of global proportions. As

1. NANOTECHNOLOGY: AN OVERVIEW Nanotechnology is the manipulation of matter on the nanoscale. A nanometer is a very small measure of length-it is one billionth of a meter‚ a length so small that only three or four atoms lined up in a row would be a nanometer. So‚ nanotechnology involves designing and building materials and devices where the basic structure of the material or device is specified on the scale of one or a few nanometers. Ultimately‚ nanotechnology will mean materials and devices
