Vegetables are excellent filler foods because they are low in fat‚ low in calories and high in fiber. It has a high nutritional value than the common potato. Background of the Study The reason why we came up with this project is because we thought of having a nutritious vegetable like “Kamote tops” into a healthy tea. We chose Kamote tops because it is high in complex carbohydrates and dietary fibers. Statement of the Problem/Objectives This study aims to find out if Kamote tops can be made into

Fibre Optics Technology over the past century has advanced greatly. Fibre optics however is being utilized since more than a hundred years. Optical fibre is a model that has evolved greatly over time. From guided transmission lights experiments to lasers and light emitting diodes (LED)‚ and to dense wavelength-division multiplexing (DWDM)‚ the area under which optical fibre can be used has expanded. One of the modern and commonly used applications
Premium Optical fiber Refractive index
an optical communication technology that uses light propagating in free space to transmit data for telecommunications orcomputer networking. "Free space" means air‚ outer space‚ vacuum‚ or something similar. This contrasts with using solids such as optical fiber cable or an optical transmission line. The technology is useful where the physical connections are impractical due to high costs or other considerations. Free-space optical communication (FSO) systems (in space and inside the atmosphere) have

MARCO C. SALUDARIO 4th Year Student Presented to: MRS. MARLITA J. DELOS SANTOS Subject Teacher 19 FEBRUARY 2013 ABSTRACT Laser communication‚ often referred to as free-space optics (FSO) or free-space laser (FSL) communication‚ is similar to fiber optic cable in terms of carrier wavelength and bandwidth capability‚ but data are transmitted directly through the atmosphere via laser beams over paths from a few meters to 4 km or longer. FSL uses lasers in the near-infrared spectrum‚ typically at

digital bit streams over optical fiber using lasers or light emitting diodes (LEDs). SONET was designed by the American National Standards Institute (ANSI) for the USA public telephone network in the mid 1980’’s due to the breakup of AT&T. With the breakup‚ numerous regional telephone companies were created and those companies encountered network problems working together as well as alone. SONET was created as the new standard for these companies to use for their fiber optic long distance cabling

waves are propagated in microwave and RF communications. The wave passing through the medium is forced to follow the path determined by the physical structure of the guide. 3. FTTH: Short for fiber-to-the-home‚ the installation of optical fiber from a telephone switch directly into the subscribers home. Fiber optic cable is an alternative to coaxial cable. 4. Simplex: refers to one-way communications where one party is the transmitter and the other is the receiver. An example of simplex communications

PC TO PC FIBER OPTIC COMMUNICATION [pic] Submitted By: lex INTRODUCTION DEFINITION The project PC to PC fiber optic communication deals with data transfer from one computer to another. It uses C programming and the serial ports of the PCs. The ports are programmed in C. We use MAX 232 to convert RS 232 logic to TTL logic and then an optical transmitter circuit to transmit data via fiber optic cable. The optical transmitter circuit has a LED which is matched as far the cable

hard and dry stools less than three times a week. In some cases‚ constipation also may make you feel bloated or sluggish or experience discomfort or pain. Fortunately‚ a few common-sense lifestyle changes‚ including getting more exercise‚ eating high-fiber foods and drinking plenty of water‚ can go a long way toward preventing or alleviating constipation. Symptoms Not having a bowel movement every day doesn’t necessarily mean you’re constipated. You’re likely constipated‚ however‚ if you: Pass a
