HISTORY OF FIBER OPTICS * In 1840‚ Daniel Colladon and Jacques Babinet demonstrated the principle of guiding light by refraction. * It was followed by a public demonstration by John Tyndal in 1852. In 1870‚ Tyndal wrote about the property of total internal reflection in his book about the nature of light. * In 1880‚ Alexander Graham Bell and Sumner Tainter invented the Photophone‚ a device capable of transmitting sound waves over beam of light. This is considered as mankind’s first attempt

Understanding Your Fats and Fiber SCI/241 June 13‚ 2013 Understanding Your Fats and Fiber According to Face the Fats the bad fats are trans fats and saturated fats‚ both of these fats raises bad cholesterol levels in the blood. Monounsaturated fats and polyunsaturated fats can lower bad cholesterol levels and are beneficial when consumed in moderation. Taking in too many fats regardless of what kind they are can eventually lead to to many calories which can lead to weight gain. High levels

FIBER TO THE HOME: THE NEW EMPOWERMENT abstract: In order to offer future higher bandwidth applications‚ the choice for a fiber to the home (FTTH) network seems to be the best candidate. Still‚ as the full deployment of a new FTTH network involves tremendous civil works and costs‚ only the highly profitable areas‚ e.g. city centers‚ are currently being installed. With the installation of such FTTH networks‚ all involved parties stay with many questions. What will the future bring on demands from

form of clothes‚ interior textiles or in the form of high performance technical textiles made of conventional or high technology fibres for various applications. A textile fibre is usually defined as a flexible‚ macroscopically homogenous cylindrical body mainly with circular cross- section having a high ratio of length to diameter (typically 100-3000: 1). Textile fibres are derived both from natural and synthetic origins. Natural fibres such as cotton‚ wool etc. are often found with lengths 1000-3000

used in processed foods such as baked goods. Fiber and lipids serve two separate functions that both help keep the body healthy. Fiber absorbs cholesterol and helps to slow the amount of glucose the body absorbs. Fiber helps collect waste and build it into one entity rather than the body having diarrhea and waste just running through the body. It allows the waste to form into a single mass before it is passed through the body. Lipids help your body collect and store energy for use

Fiber optic communication ABSTRACT FIBRE-OPTICS COMMUNICATION Most reference materials that discuss the historical perspective mention about Indian smoke signals. None of these primitive systems was secure due to the spreading of the unguided light. Ideally‚ a communication system should be secure and should not require installation of a cumbersome physical media. Fiber optics satisfied these desires‚ and as early as 1958‚ fiber-optic equipment was being focused for use in the factory. The fiber-optic
