Exercise physiology loss of integrity to the blood brain barrier. Hyperthermia also can lower cerebral blood flow, and raise brain temperature. Researchers once attributed fatigue to a build-up of lactic acid in muscles. However, this is no longer believed. Rather, lactate may stop muscle fatigue by keeping muscles fully responding to nerve signals. The available oxygen and energy supply, and disturbances of muscle ion homeostasis are the main factor determining exercise performance, at least during brief very intense exercise. Each muscle contraction involves an action potential that activates voltage sensors, and so releases Ca ions from the muscle fibre’s sarcoplasmic reticulum. The
Oxygen plant in refineries. The use of oxygen in the fish farming helps increase the survival and fertility ratios and reduce the incubation period. Along with fish culture, oxygen is applied for shrimps, crabs and mussels rearing. In glass furnaces oxygen is effectively used for burning temperature increase and burning processes improvement. The use of oxygen in incinerators allows significantly increased flame temperatures and eventually ensures enhanced cost efficiency and incinerator production capacity. Gas separation by adsorption systems is based on the fixation of various gas mixture components by a solid substance called adsorbent. Physically, this phenomenon is brought about by the
