Abstract Through experimentation looking at freezing point depression and heat of dissolution, potassium chloride’s effect as a deicer was measured. In solutions, KCl lowered the freezing point of water below zero degrees Celsius, and was seen to increase in magnitude as the concentration increased. The enthalpy of the dissolution was found to be endothermic, meaning […]

Textile tests are important for the store buyer, the salesman, and the consumer. A number of different tests may be fiber to textiles in order to evaluate them for specific uses, and in addition several tests may be required to determine whether a fabric can perform well in a particular use. To ensure accuracy and […]

Extensions of cognition do non ever enlarge our capacity for control. This holds true for our relation to nature. some of whose phenomena are alterable by adult male while others are non. Despite all addition in our information about heavenly phenomena some lie wholly beyond human influence. For case a geologist surveies the nature of […]

It was a bitterly cold night, and the freezing air was piercing my uniform and stinging my numb flesh like darts. I nervously glanced around making sure that I could not be seen by anyone, as I was worried that I might be caught. I was not supposed to be on this deck let alone […]

Thermoset process scrap costs companies millions of dollars annually. Specific thermoplastics could benefit from the addition of recycled thermoset material. The incorporation of thermoset regrind into thermoplastic material would provide a viable alternative for the thermoset scrap that is currently sent to the landfills. When a thermoset part has been cross-linked, that material either has […]

Production impact Environmental and health concerns right to doorstep. Chop down four or five trees to make 500 kg of fluffy wood pulp baby will use in 2  years. (Catherine McDiarmid, 1997 Environmental Concerns) Then you will need just for your child, over 2,800 cubic meters of nonrenewable natural gas to make 325 kg of […]

Introduction & Background of the study Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam currently made for thermal insulation and craft applications examples of these Styrofoam are disposable coffee cups, coolers, or cushioning material in packaging. Styrofoam is widely used for insulator and packaging. The disposal of these products creates environmental pollution because […]

With an increase in industrial development and population growing at an alarming rate, waste and for that matter waste disposal, is becoming a growing problem worldwide. This constitutes a major problem especially for most countries in the developing world as a result of inadequate mechanisms for the proper disposing of wastes. According to Narayana (2008), […]

Tom Alessio, Marketing Vice President at Porcini’s Inc. , of Boston, was pondering issues raised by a potential expansion of his company’s restaurant business. The domestic market for full-service chain restaurants was nearing its saturation point at both in-city and shopping mall locations. The big chains were looking overseas for growth, but as a small […]

Biodegradable matter is generally organic materials such as plant and animal matter and other substances originating from living organisms, or artificial materials that are similar enough to plant and animal matter to be put to use by microorganisms. Some microorganisms have a naturally occurring, microbial catabolic diversity to degrade, transform or accumulate a huge range […]

The formation of nylon by a condensation polymerization reaction at the interface of water and hexane, two immiscible solvents. The lower water layer contains the compound hexanedioyl dichloride, Cl C(CH2)4C O O Cl hexanedioyl dichloride The reaction produces nylon and HCl(aq). The polymer forms at the interface between the two solutions and is drawn out […]

 SWOT Analysis Environment Fiber optics is a new technology that uses rays of light instead of electricity to transmit information over optical fibers at very high speeds. The optical fibers are usually thin strands of glass that are combined into cables and used to send information and computer data in the form of pulses of […]

Fiber optics was first applied back in sass when the French Chapped brothers invented the first “optical telegraph”. It was a system consisted of mounted lights on multiple towers where operators would relay a message from one tower to the other. Ever since then, fiber optics was enhanced further and many other applications were covered. […]

With this code the workforce and partners of the Verizon Company are obligated to be judgmental over […]

Now a days we are using copper wires as they are the most cost effective and reliable interconnect in parallel machines. However as machines grow more powerful, wire density becomes critical making fiber possible alternatives because of their small wire size. Fiber optics are used mainly to use effectively its high bandwidth. On a single […]

Structured Cabling Technology and Market Assessment January 13, 2013 When we started researching the structured cabling market a few months ago, it seemed like not much had changed in the past three years. Some of the individuals we interviewed for this report thought so, too. But as it turns out, there have been many changes […]

Fiber optics produced by special methods from silica glass and quartz which replaced copper wire is very useful in telecommunications, long distance telephone lines and in examining internal parts of the body (endoscopy). Equipment for photography is available with all current fiber-optic endoscopes. Through a process known as total internal reflection, light rays beamed into […]
