Aherne-Williams Fibre-Optic Telecommunications Systems: Fibre-optic telecommunications is simply a method of transmitting information from one place to another extremely fast. This is done by shooting pulses of light through an optical fibre. Creating the optical signal involving the use of a transmitter‚ relaying the signal along the fiber‚ ensuring that the signal does not become too distorted or weak‚ receiving the optical signal‚ and converting it into an electrical signal. An optic-fibre is a small

Summary and Recommendations: ODI Inc wants to launch a product that is completely new‚ technologically advanced and performs well as demonstrated in the initial tests. The ODI lens helps farmers by controlling cannibalization among birds at farms. Cannibalization is an issue that is more prevalent in farms with a large number of chickens as they fight for food and their territory. ODI lens helps in distorting the vision of the chicken and thereby curbing both these issues without causing much trauma

TECHNOLOGY FIBRES FOR TECHNICAL TEXTILES 1 INTRODUCTION Human life is surrounded by hundreds of textile fibres either in the 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

Slow-Oxidative (Type I) Muscle Fibres Shelby Daye Skeletal muscles are classified as striated and voluntary. They are found in muscles that maintain low-intensity contractions for long periods without fatigue. A single skeletal muscle cell is referred to as a muscle fibre. There are three types of muscle fibres found in the human skeletal muscle system including slow-oxidative fibres‚ fast-oxidative fibres and fast-glycolytic fibres. These three fibres are each defined by their biochemical capacities1
