Expert Author: Thomsen Lucas The kids are smarter nowadays; they are not as dumb as we were when we were of their age. As kids as far as I remember I was very dumb and hardly spoke anything during my initial years of schooling. My class teacher always complained that never spoke anything I class and my handwriting was very shabby and she could never clearly make out what I used to write in my books. Expert Author: Amit Koithiyal Used for thousands of years as an ancient healing practice, holistic medicine has now begun to be recognized in conventional medical arena also to provide an extensive and healthier view of patient care. An alternative medicine degree holder addresses the emotional, physical and spiritual aspects of a person's health and gets an opportunity to explore a variety of fields including Homeopathy, natural health, massages and acupuncture to attain a career as a professional natural health practitioner. Expert Author: Louis Wright Few things are as a great as the years spent gaining your college education. When you attend Westmont College, you'll also be equipping yourself with the skills and knowledge for your future career, and (hopefully) guard yourself against any financial difficulties. With that said, good luck staying within any sort of budget while attending college. First off, the College is located in the beautiful California Coastal Mecca of Montecito. Yes, that Montecito, the one where Oprah lives, next to sunny Santa Barbara. If your parents are footing the bill, lucky you! Be sure to send them a "thank you" note when you graduate. Expert Author: Vara Lakshmi A Pressure Vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. Pressure vessels are used in a variety of applications in both industry and the private sector. They appear in these sectors as industrial compressed air receivers and domestic hot water storage tanks. Expert Author: Jason John Can human body produce electricity. When we hear it first it is unbelievable. But when we think yes, we know that human body has minor electric currents flowing through it. But is there any way to prove it? To prove that the human body is able to produce electric current with the help of a simple experiment. Expert Author: Thomsen Lucas There are certain factors that are responsible for the development of a child. While few factors have to be taken care of by the parents at home, rest are taken care of at schools. As the child first leaves the comfort and acquainted faces of its family members, and goes to a school, it needs certain MAlebog and educational toys to help them learn things in a fun way. Expert Author: Vara Lakshmi A Centrifugal Fan is a mechanical device for moving air or other gases. It has a fan wheel composed of a number of fan blades, or ribs, mounted around a hub. The gas enters from the side of the fan wheel, turns 90 degrees and accelerates due to centrifugal force as it flows over the fan blades and exits the fan housing. Expert Author: Vara Lakshmi A Ball Valve is a valve with a spherical disc, the part of the valve that controls the flow through it. The sphere has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. Expert Author: Vara Lakshmi Breath Alcohol Analyser is a device for estimating blood alcohol content (BAC) from a breath sample. The U.S. National Highway Traffic Safety Administration maintains a Conforming Products List of breath alcohol devices approved for evidentiary use, as well as for preliminary screening use. Expert Author: Vara Lakshmi An Electrostatic Precipitator (ESP), or Electrostatic Air Cleaner is a particulate collection device that removes particles from a flowing gas (such as air) using the force of an induced electrostatic charge. Electrostatic precipitators are highly efficient filtration devices that minimally impede the flow of gases through the device, and can easily remove fine particulate matter such as dust and smoke from the air stream. In contrast to wet scrubbers that apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and therefore is very efficient in its consumption of energy (in the form of electricity). Expert Author: Vara Lakshmi An Air Compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible, so the main action of a pump is to pressurize and transport liquids. Expert Author: Vara Lakshmi A Positive Displacement Meter is a type of Flow Meter that requires the fluid being measured to mechanically displace components in the meter in order for any fluid flow to occur. Positive displacement (PD) flow meters make volumetric flow measurements taking finite increments or volumes of the fluid. Expert Author: Vara Lakshmi An Aerial Device or Elevating Work Platform is a mechanical device used to provide temporary access for people or equipment to inaccessible areas, usually at height. They are generally used for temporary, flexible access purposes such as maintenance and construction work or by fire fighters for emergency access, which distinguishes them from permanent access equipment such as elevators. Expert Author: Vara Lakshmi Belt Conveyor moves an object from one point to another consist of two or more pulleys, with a continuous loop of material - the conveyor belt - that rotates about them. One or both of the pulleys are powered, moving the belt and the material on the belt forward. The powered pulley is called the drive pulley while the un-powered pulley is called the idler. Expert Author: Vara Lakshmi A sensor is a device, which receives and responds to a signal or stimulus. The "stimulus" means a property or a quantity that needs to be converted into electrical form. Hence, sensor can be defined as a device, which receives a signal and converts it into electrical form, which can be further used for electronic devices. Expert Author: Vara Lakshmi A Crane is a lifting machine, generally equipped with a winder (also called a wire rope drum), wire ropes or chains and sheaves that can be used both to lift and lower materials and to move them horizontally. It uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. Expert Author: Vara Lakshmi A Furnace is a device used for heating. The term furnace is used exclusively to mean industrial furnaces which are used for many things, such as the extraction of metal from ore (smelting) or in oil refineries and other chemical plants, for example as the heat source for fractional distillation columns. Expert Author: Vara Lakshmi A Heater is any object that emits heat or causes another body to achieve a higher temperature. In a household or domestic setting, heaters are usually appliances whose purpose is to generate heating (i.e. warmth). Ceramic elements are the heaters of choice in most applications, but quartz heaters are favoured in industrial applications where rapid heater response is necessary. Quartz heaters provide infrared radiation in the medium wavelength of 1.5 to 5.6 microns. Expert Author: Vara Lakshmi An Electric Motor uses electrical energy to produce mechanical energy, very typically through the interaction of magnetic fields and current-carrying conductors. The reverse process, producing electrical energy from mechanical energy, is accomplished by a generator or dynamo. Expert Author: Vara Lakshmi A spring is an elastic object used to store mechanical energy. Springs are usually made out of hardened steel. Small springs can be wound from pre-hardened stock, while larger ones are made from annealed steel and hardened after fabrication. Some non-ferrous metals are also used including phosphor bronze and titanium for parts requiring corrosion resistance and beryllium copper for springs carrying electrical current (because of its low electrical resistance).
