For example, levels of fine particulate matter (PM 2.5) in a large hotel event room (4,023m 3) increased from 2–3 μg/m 3 to as high as 819 μg/m 3 (interquartile range: 761–975 μg/m 3) when 59–86 people were using e-cigarettes. [35]
The WHO model list of essential in vitro diagnostics, or WHO list of essential diagnostic tests (EDL) is a World Health Organization (WHO) priority list of medical tests that provides guidance for individual countries on which tests to use and which not to. [ 1][ 2] It was first published in 2018, [ 1][ 3] then revised in 2019, [ 1][ 3] and a ...
In blue, the point (4, 210°). In mathematics, the polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction. The reference point (analogous to the origin of a Cartesian coordinate system) is called the pole, and the ...
The (infinitesimal) strain tensor (symbol ) is defined in the International System of Quantities (ISQ), more specifically in ISO 80000-4 (Mechanics), as a "tensor quantity representing the deformation of matter caused by stress. Strain tensor is symmetric and has three linear strain and three shear strain (Cartesian) components." [ 6]
Euler–Bernoulli beam theory (also known as engineer's beam theory or classical beam theory) [ 1] is a simplification of the linear theory of elasticity which provides a means of calculating the load-carrying and deflection characteristics of beams. It covers the case corresponding to small deflections of a beam that is subjected to lateral ...
