Operational conditions in a W-clad tokamak

Influence of unsuitable operational conditions on the transient performance of a small hydrogen liquefier

Joule-Thomson cooling systems are used in refrigeration processes such as cryogenic gas liquefaction. Although extensive studies have been carried out by researchers, most of them include cryogenic heat exchangers and their associated fields. In the current study, an attempt was made to indicate the effect of using inappropriate operational conditions in a cryogenic Joule-Thomson cooling system...

Bernstein rays in a Tokamak plasma in the electron - cyclotron heating conditions

TECHNOLOGICAL advances in the construction of high-frequency tubes (gyrotrons) (ALIKAEV et al., 1978; .TORY, 1978) have produced a sustained interest in the possibility of using microwave energy in the electron-cyciotron frequency range (ECF) o = ace, as a promising additional heating scheme for Tokamak plasmas. Nearly all proposed experiments, which will become operative in the next two years ...

Operational Medical Issues in Hypo- and Hyperbaric Conditions

The relation between the presence of a patent foramen ovale (PFO) and the risk of decompression illness (DCI) remains controversial. PFO is a common finding in the general population, with an autopsy prevalence of about 25%. Recent review articles in the diving literature have concluded the presence of a PFO may increase the relative risk for DCI but the absolute risk remains low. In space oper...
