Atlas
A collection of maps. The name is derived from frontispiece of early atlases, including that of Mercator in 1636, showing the god Atlas supporting the world. Maps show spatial distribution. Global maps influence people’s image of the world. In the latter half of C20th Atlases began to be widely used to present social, historical and economic data as well as geographic data. Notable examples include The New State of the World Atlas, The World Bank Atlas, Third World Atlas.
a computer-controlled instrument which measures the Staple Length, Staple Strength and Position of Break of individual staples. In operation, a continuous belt conveys each staple between an array of lights and an array of photocells, which detects the ends of the staple and enables the length (in millimetres) to be measured. The staple is then grasped by two sets of jaws and broken. The force required is measured in Newtons. The two pieces of the broken staple are individually collected and weighed and, from the masses, lengths and core test yield, the staple linear density (thickness) is calculated and expressed in kilotex; the Staple Strength is expressed as Newtons/kilotex (N/ktex). The masses of the two pieces are also used to calculate the Position of Break.
