Outremer is a tactical board wargame of personal combat for two or more players in which one side controls one or more Crusader knights, and the other side controls opposing Saracens. [ 1 ] The rule system was first developed for a previous game published by Standard Games, Cry Havoc , although Outremer includes several revisions and ...
The Crusader states, or Outremer, were four Catholic polities that existed in the Levant from 1098 to 1291. Following the principles of feudalism , the foundation for these polities was laid by the First Crusade , which was proclaimed by the Latin Church in 1095 in order to reclaim the Holy Land after it was lost to the 7th-century Muslim ...
Although theoretically trimix can be blended with almost any combination of helium and oxygen, a number of "standard" mixes have evolved (such as 21/35, 18/45 and 15/55—see Naming conventions). Most of these mixes originated from starting by decanting a given pressure of helium into an empty cylinder, and then topping up the mix with 32% nitrox.

Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen (O 2) at increased partial pressures.Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs, and eyes.
A breathing gas is a mixture of gaseous chemical elements and compounds used for respiration. Air is the most common and only natural breathing gas. Other mixtures of gases, or pure oxygen, are also used in breathing equipment and enclosed habitats such as scuba equipment, surface supplied diving equipment, recompression chambers, high-altitude mountaineering, high-flying aircraft, submarines ...
35–45 nmol/L (nM) Arterial oxygen partial pressure (P a O 2) 10–13 kPa 75–100 mmHg [13] A low PaO 2 indicates abnormal oxygenation of blood and a person is known as having hypoxemia. (Note that a low PaO 2 is not required for the person to have hypoxia as in cases of Ischemia, a lack of
Excessive exposure to oxygen can lead to oxygen toxicity, also known as oxygen toxicity syndrome, oxygen intoxication, and oxygen poisoning.There are two main ways in which oxygen toxicity can occur: exposure to significantly elevated partial pressures of oxygen for a short period of time (acute oxygen toxicity), or exposure to more modest elevations in oxygen partial pressures but for a ...
