cloth. Good portions of these are combinations of synthetic fibers woven or threaded together to make a final product. These synthetic fibers are a large group of polymers. Synthetic polymers offer more possibilities‚ since they can be designed with molecular structures that impart properties for desired end uses. All fibers are ploy-something or polymers. That means they are long strings of repeating chemical elements. Some fibers come from ground plants that synthesize connected units of cellulose

A passive optical network (PON) is a telecommunications network that uses point-to-multipoint fiber to the premises in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises. A PON consists of an optical line terminal (OLT) at the service provider’s central office and a number of optical network units (ONUs) near end users. A PON reduces the amount of fiber and central office equipment required compared with point-to-point architectures. A passive optical

Network and Telecommunication Concepts May 14‚ 2005 FIBER OPTICS IN OUR SCHOOLS Fiber optic refers to the medium and the technology associated with the transmission of information as light impulses along a glass or plastic wire or fiber‚ about the thickness of a human hair. Fiber optic wire carries much more information than conventional copper wire‚ and is far less subject to electromagnetic interference. A single glass fiber can carry the equivalent of 100 channels of television or 100

Synthetic Fibers Industry Synthetic fibers are the result of extensive research by scientists to improve on naturally occurring animal and plant fibers. In general‚ syntheticfibers are created by forcing‚ usually through extrusion‚ fiber forming materials through holes (called spinnerets) into the air‚ forming a thread. Before synthetic fibers were developed‚ artificially manufactured fibers were made from cellulose‚ which comes from plants. These fibers are called cellulose fibers. Raw materials:

Rachel Hahn Cheryl Blackwell Seminar November 2012 Optical Illusions An illusion is the distorted perception of a stimulus. They are not to be confused with hallucinations‚ which are false perceptions when there is no presence of a stimulus‚ in contrast‚ illusions are the misinterpretation of a true sensation (Illusion Wikipedia). Illusions are mundane phenomena‚ and are experienced by nearly everyone in similar ways where hallucinations are a personal experience and are typically limited

Fiber Intermediates: Fiber Intermediates have large production capacity in India. Globally the demand for all categories of Fiber is increasing at a pace of 3-4 MT annually. Polyester is accounted for 70% of the total growth of fiber in all categories in next decade. This global demand scenario has a positive impact on the Indian market as well. Polyester demand in India is likely to grow at 12% Y-o-Y to .5 MPTA. Demand of Polyester will also result into demand growth of PX which is expected to grow

[pic] An optical illusion also called a visual illusion is characterized by visually perceived images that differ from objective reality. The information gathered by the eye is processed in the brain to give a percept that does not tally with a physical measurement of the stimulus source. There are three main types: literal optical illusions that create images that are different from the objects that make them‚ physiological ones that are the effects on the eyes and brain of excessive stimulation

"A carbon fiber is a long‚ thin strand of material about 0.005-0.010 mm in diameter and composed mostly of carbon atoms. The carbon atoms are bonded together in microscopic crystals that are more or less aligned parallel to the long axis of the fiber. The crystal alignment makes the fiber incredibly strong for its size. Several thousand carbon fibers are twisted together to form a yarn‚ which may be used by itself or woven into a fabric. The yarn or fabric is combined with epoxy and wound or molded
