Krypton (from Ancient Greek: κρυπτός, romanized : kryptos 'the hidden one') is a chemical element; it has symbol Kr and atomic number 36. It is a colorless, odorless noble gas that occurs in trace amounts in the atmosphere and is often used with other rare gases in fluorescent lamps. Krypton is chemically inert .
Ethyl methanesulfonate ( EMS) is an organosulfur compound with the formula CH3SO3C2H5. It is the ethyl ester of methanesulfonic acid. A colorless liquid, it is classified as an alkylating agent. EMS is the most commonly used chemical mutagen in experimental genetics. [ 4][ 5] Mutations induced by EMS exposure can then be studied in genetic ...
There are 34 known isotopes of krypton ( 36 Kr) with atomic mass numbers from 69 through 102. [ 5][ 6] Naturally occurring krypton is made of five stable isotopes and one ( 78. Kr. ) which is slightly radioactive with an extremely long half-life, plus traces of radioisotopes that are produced by cosmic rays in the atmosphere .
The molecular mass ( m) is the mass of a given molecule. The unit dalton (Da) is often used. [ 1] Different molecules of the same compound may have different molecular masses because they contain different isotopes of an element. The derived quantity relative molecular mass is the unitless ratio of the mass of a molecule to the atomic mass ...
9-1-1 emergency dispatch center. An emergency medical dispatcher is a professional telecommunicator, tasked with the gathering of information related to medical emergencies, the provision of assistance and instructions by voice, prior to the arrival of emergency medical services (EMS), and the dispatching and support of EMS resources responding ...
On July 26, the bridge's weight limit was reduced to 8 tons, or 16,000 pounds. Vehicles exceeding this limit are no longer permitted to cross the bridge. This marks the third set of restrictions ...
Dimensional weight, also known as volumetric weight, is a pricing technique for commercial freight transport (including courier and postal services ), which uses an estimated weight that is calculated from the length, width and height of a package. The shipping fee is based upon the dimensional weight or the actual weight, whichever is greater.
