1 The material is another important basis for computation of cost. 2  The material is usually computed by yard. 3  A couch on average uses from 18 to 22 yards of fabric. 4  Some fabrics cost as low as $15 per yard to as high as $180 for fabrics made of silk and wools.

The major energy loss of high-energy (relativistic) electrons (energy greater than about 10 MeV, depending somewhat upon material) occurs from the emission of bremsstrahlung, and this is the major source of gamma rays in a high-energy cosmic-ray shower. See Electromagnetic radiation.
mitosis / cell division. Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus. Mitosis is conventionally divided into five stages known as prophase, prometaphase, metaphase, anaphase, and telophase. While mitosis is taking place, there is no cell growth and all of the cellular energy is focused on cell division.
