The biology of depression is the attempt to identify a biochemical origin of depression, as opposed to theories that emphasize psychological or situational causes. Scientific studies have found that different brain areas show altered activity in humans with major depressive disorder (MDD) . [ 1 ]
A contact explosive is a chemical substance that explodes violently when it is exposed to a relatively small amount of energy (e.g. friction, pressure, sound, light). Though different contact explosives have varying amounts of energy sensitivity , they are all much more sensitive relative to other kinds of explosives.
Total body disruption is the most severe and invariably fatal primary injury. [2] Primary injuries are especially likely when a person is close to an exploding munition, such as a land mine. [ 3 ] The ears are most often affected by the overpressure, followed by the lungs and the hollow organs of the gastrointestinal tract .
The most widely used explosives are condensed liquids or solids converted to gaseous products by explosive chemical reactions and the energy released by those reactions. The gaseous products of complete reaction are typically carbon dioxide , steam , and nitrogen . [ 18 ]
A reaction must be capable of being initiated by the application of shock, heat, or a catalyst (in the case of some explosive chemical reactions) to a small portion of the mass of the explosive material. A material in which the first three factors exist cannot be accepted as an explosive unless the reaction can be made to occur when needed.
The basic unit of the Reactome database is a reaction; reactions are then grouped into causal chains to form pathways [115] The Reactome data model allows us to represent many diverse processes in the human system, including the pathways of intermediary metabolism, regulatory pathways, and signal transduction, and high-level processes, such as ...
Black Friday tends to cause a bit of chaos every year. Especially because it’s not so much a single day of good deals as a constantly expanding period of non-stop sales (and annoying ads). It ...
