1 Various units are used to refer to the measurement of a fiber, such as: the denier and tex (linear mass density of fibers), super S (fineness of wool fiber), worsted count, woolen count, cotton count (or Number English Ne), Number metric (Nm) and yield (the reciprocal of denier and tex).hread count or threads per inch (TPI) is a measure of the coarseness or fineness of fabric. It is measured by counting the number of threads contained in one square inch of fabric or one square centimeter, including both the length (warp) and width (weft) threads.
However, in the stratosphere, our friend the ozone layer is especially good at absorbing UV radiation; which shields us from most of these high-energy rays, and also heats this layer as the UV photons transfer their energy to the oxygen (ozone is an unusual type of oxygen molecule, O 3) molecules.
20 Questions: 2010 Update Section I: OZONE IN OUR ATMOSPHERE. Ozone in the stratosphere absorbs a large part of the Sunâs biologically harmful ultraviolet radiation. Stratospheric ozone. is considered âgoodâ ozone because of this beneficial role. In contrast, ozone formed at Earthâs surface in excess of natural. amounts is considered âbadâ ozone because it is harmful to humans, plants, and animals.
