The present thesis considers the premise that breath-holding in aquatic sports, primarily swimming, in order to enhance performance, can potentially cause adaptation to tissue hypoxia. To investigate this theory, a series of studies needed to be performed: I. Analysis of variability in individuals’ responses to hypoxia, to evaluate the range …
Plasma facing components (PFC) in fusion devices are exposed to plasma. Plasma-wall interaction processes are important as they impose a series of constraints on the components. The lifetime of the PFCs is dominantly determined by two processes: erosion and fuel retention. At the first wall the erosion is caused by …
Atmospheric mercury (Hg) plays an important role in the biogeochemical Hg cycle. Hg species in the atmosphere are present in very low concentrations. While gaseous elemental mercury (GEM) is relatively inert, gaseous oxidized (GOM) and particulate-bound (PBM) mercury are highly reactive. These characteristics of atmospheric Hg species make the speciation …
In this thesis we present the development of the device for the removal of carbon deposits in fusion reactors. Amorphous hydrogenated carbon deposits (a-C:H) represent a major problem for smooth operation of future fusion reactors with divertors containing carbon tiles, because they cause retention of radioactive tritium. There are techniques …
