The saturation vapor density (SVD) is the maximum density of water vapor in air at a given temperature. [1] The concept is related to saturation vapor pressure (SVP). It can be used to calculate exact quantity of water vapor in the air from a relative humidity (RH = % local air humidity measured / local total air humidity possible ) Given an RH percentage, the density of water in the air is ...
The World Health Organization (WHO) has introduced a TDI for melamine as 0.2 milligrams (mg)/kg body weight (b.w.) as of 2008. [5] Similarly the established TDI range for dioxin according to WHO is 1-4 picograms toxic equivalency/kg body weight as of 1998. [6]
ρ 0 is the density of air at sea level; H is the scale height of the atmosphere; z is the height in question; The optical depth of a plane parallel cloud layer is given by [3] = [] / where: Q e is the extinction efficiency; L is the liquid water path
Segara Anak is a crater lake in the caldera that formed during the explosive volcanic eruption of Mount Samalas in 1257. The caldera is next to Mount Rinjani on Lombok Island in Indonesia . "Segara Anak" means "child of the sea" and refers to the blue lake's resemblance to the sea.
When the score distribution is approximately normally distributed, sten scores can be calculated by a linear transformation: (1) the scores are first standardized; (2) then multiplied by the desired standard deviation of 2; and finally, (3) the desired mean of 5.5 is added.
Blaise Pascal [a] (19 June 1623 – 19 August 1662) was a French mathematician, physicist, inventor, philosopher, and Catholic writer.. Pascal was a child prodigy who was educated by his father, a tax collector in Rouen.
