Basic decompression theory and use of decompression tables is part of the theory component of training for commercial divers, [130] and dive planning based on decompression tables, and the practice and field management of decompression is a significant part of the work of the diving supervisor.
Equivalent air depth – Method of comparing decompression requirements for air and a given nitrox mix; Equivalent narcotic depth – Method for comparing the narcotic effects of a mixed diving gas with air; History of decompression research and development – Chronological list of notable events in the history of diving decompression.
Decompression profiles based on the Thermodynamic model compared with the US Navy table for the same depth and bottom time. The thermodynamic model was one of the first decompression models in which decompression is controlled by the volume of gas bubbles coming out of solution. In this model, pain only DCS is modelled by a single tissue which ...
The stability of an air mass may be shown using a third letter, either "k" (air mass colder than the surface below it) or "w" (air mass warmer than the surface below it). [3] An example of this might be a polar air mass blowing over the Gulf Stream , denoted as "cPk".
Partial melting is the phenomenon that occurs when a rock is subjected to temperatures high enough to cause certain minerals to melt, but not all of them. Partial melting is an important part of the formation of all igneous rocks and some metamorphic rocks (e.g., migmatites), as evidenced by a multitude of geochemical, geophysical and petrological studies.
Haldane's decompression model is a mathematical model for decompression to sea level atmospheric pressure of divers breathing compressed air at ambient pressure that was proposed in 1908 by the Scottish physiologist, John Scott Haldane (2 May 1860 – 14/15 March 1936), [1] who was also famous for intrepid self-experimentation.
Processes in the thermal degradation of organic matter at atmospheric pressure.. Thermal decomposition, or thermolysis, is a chemical decomposition of a substance caused by heat.
Decompression melting occurs because of a decrease in pressure. [66] It is the most important mechanism for producing magma from the upper mantle. [67] The solidus temperatures of most rocks (the temperatures below which they are completely solid) increase with increasing pressure in the absence of water.
