Textile fibers, threads, yarns and fabrics are measured in a multiplicity of units.. A fiber, a single filament of natural material, such as cotton, linen or wool, or artificial material such as nylon, polyester, metal or mineral fiber, or human-made cellulosic fibre like viscose, Modal, Lyocell or other rayon fiber is measured in terms of linear mass density, the weight of a given length of ...
If the liquid nitrogen manages to pool anywhere, it will burn severely. As liquid nitrogen evaporates it reduces the oxygen concentration in the air and can act as an asphyxiant, especially in confined spaces. Nitrogen is odorless, colorless, and tasteless and may produce asphyxia without any sensation or prior warning. [20] [21] [22]
For example, moisture (usually measured as a percentage) is a common specification in commercial food production. [1] There are many applications where trace moisture measurements are necessary for manufacturing and process quality assurance. Trace moisture in solids must be known in processes involving plastics, pharmaceuticals and heat treatment.
The weights are in denominations of 7 pounds (corresponding to a unit known as the clip or wool-clip), 14 pounds (stone), 56 pounds (4 stone) and 91 pounds (1 ⁄ 4 sack or woolsack). [ 18 ] [ 19 ] The 91-pound weight is thought to have been commissioned by Edward III in conjunction with the statute of 1350, while the other weights are thought ...
There are many more examples where US units differ from UK units than the gallon; think of pint as an example. Not to forget differences in mass units for dry, wet and liquid matters as ton, ounce etc. etc. One of the huge drawbacks of non-SI/metric units. And pints and fluid ounces, of course (see gallon, pint, fluid ounce).
Weight is measured in ounces and pounds (avoirdupois) as in the U.S. Volume is measured in imperial gallons , quarts , pints , fluid ounces , fluid drachms , and minims . The imperial gallon was originally defined as 10 pounds (4.5359 kg) of water in 1824, and refined as exactly 4.54609 litres in 1985.
It can also be measured automatically much more quickly, by a chemiluminescence analyzer, which determines nitrogen oxide levels from the light they give off. In the UK, for example, there are over 200 sites where NO 2 is continuously monitored by chemiluminescence. [44] Air monitoring stations sample and measure multiple pollutants.
Zara was established by Amancio Ortega Gaona in 1975. Their first shop was in central A Coruña, in Galicia, Spain, where the company is still based.They initially called it 'Zorba' after the classic 1964 film Zorba the Greek, but after learning there was a bar with the same name two blocks away, rearranged the letters to read 'Zara'.
