These days‚ in many homes‚ it is virtually impossible to have a so called modern kitchen‚ without having a microwave oven in it. The microwave oven could probably occupy the second place (after the refrigerator)‚ in terms of dependence‚ in the kitchen. This magical piece of technology has revolutionized the way people‚ and the food industries cook food. The microwave oven is only a natural evolution of technology; to fit into this fast-paced world. As in every evolutionary process‚ one must look

TERRESTRIAL MICROWAVE COMMUNICATION SYSTEM DESIGN DESCRIPTION OF THE MICROWAVE BEAM: 1. The microwave beam behaves like a light beam and it tends to follow a straight line and azimuth. 2. The changes on temperature‚ pressure and relative humidity tends to refract the microwave beam. So it will follow on a slightly curved path. The radio horizon exists. 3. It is diffracted when grazing over an obstacle. A small shadow area created when some of the energy is redirected. 4. The beam

Both creations were formed by one entity with help from other gods or entities. Darkness is a similar theme in the stories of both creations. Both creations start with an emptiness. They both entail elements of the earth and sky yet their creators are different. The Norse creation

experiment? After all‚ complex things such as computers‚ televisions‚ and microwaves had to have had a great impact on society. And so did simpler things‚ such as bar codes‚ plastic‚ and Velcro. By 1976‚ over 60% of U.S. households were using microwaves‚ just 30 years after its first invention. Today‚ microwaves are used all around the world‚ resulting in fresher food‚ less waste‚ and money saved. But how did the microwave get started? Who invented them and how did the inventor make such an astounding

A BASIC STUDY ON SIMULTANEOUS HEATING WITH MICROWAVES AND ULTRASOUND USING COAXIAL‚ TYPE APPLICATOR Abstract- A new heating method for hyperthermia using microwave and ultrasound simultaneously is proposed‚ and temperature distributions are obtained by computer simulations. The results have shown that the simultaneous use of microwave and ultrasound can heat wider and deeper region than the sole use‚ and can reduce the input power of microwave and ultrasound. This implies that we can reduce

INTRODUCTION Radiation‚ flow of atomic and subatomic particles and of waves‚ such as those that characterize heat rays‚ light rays‚ and X rays. All matter is constantly bombarded with radiation of both types from cosmic and terrestrial sources. This article delineates the properties and behaviour of radiation and the matter with which it interacts and describes how energy is transferred from radiation to its surroundings. Considerable attention is devoted to the consequences of such an energy

Answer: Radiation has a profound effect on matter. Particularly in forms where it has high energy. There are basically two kinds of radiation‚ and they are electromagnetic energy and particulate radiation. Low energy electromagnetic radiation isn’t generally hazardous‚ as long as the field strengths are low. You wouldn’t want to stand in front of a radar antenna when it’s radiating‚ but we are swept by low power electromagnet energy all the time. Those so-called radio waves are everywhere. Light

In 1894 the microwave was invented. Mistakes can cause new discoveries. Mistakes have lead to the invention of the microwave‚ ancient artifacts in Troy were found‚ and can cause major damage to the earth. So people learn from their mistakes. To begin with‚ two friends decided to dig up trenches to find ancient artifacts. They did this because they wanted to have a piece of history from the town of Troy. According to text 1 paragraph 7 it states‚ “He had workers open up huge trenches in the
