Skeletal muscles are attached to the bones of the skeleton. They serve to produce movements and are used in locomotion, maintenance of posture, and almost in any activities a body performs. Microscopically, their cells are elongated and multinuclear, and the contractile elements within them show cross-striations.… Surrounding the whole muscle is a layer of…

A Review and Analysis of Paper Recycling Methods Introduction Normally, waste paper in the UK is amassed and collected by a service provider to be piled up before selling it to paper mills. Prior to the collapse of the market, millions of bushels of eco-friendly or recyclable wastes generated annually was sent to China, where these recyclable wastes, like paper, glass, wood, and plastic are recycled or processed and utilised to produce or construct electrical products, automobiles, and houses (Young 1995).…
