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 …

Adaptation to altitude can enhance performance if the hypoxic dose and the frequency of the exposures are appropriate. While many hypoxic training modalities exist, the protocols utilizing short intermittent hypoxic exposures are gaining popularity. However, the effects of such novel hypoxic protocols on athletic performance are unclear. The aim of …

The aim of the present thesis was to examine the effect of acute and long-term normobaric hyperoxic exposure on selected haemodynamic and haematological responses during resting and exercise conditions in healthy aerobically well-trained males. This purpose was evaluated in four separate studies, and each of them had a specific aim …

The past fifteen years has seen the rapid development of various wireless communication devices, which operate at microwave or milimeterwave frequencies (mobile phones, wireless local-area networks (LAN), Bluetooth, etc.). At the same time, this progress has stimulated the development of new materials and process technologies, which enable the size reduction …

Minimally invasive surgery is one of the most promising trends in medicine. Despite of its obvious advantages - the use of small incisions reducing trauma and risk of infection - it still represents a great challenge for the surgeon, as visual guidance and dexterity are severely impaired. In the case …

Engineered nanofibers and nanoparticles are recognized as capable of inducing cellular perturbations according to the oxidative stress paradigm or by interacting directly with biological membranes. A number of authors in their investigations with the nanofibres and nanoparticles has reported the ability of nanofibers and nanotparticle to cause the different damage …

The thesis presents experimental studies of colloidal interactions and novel colloidal structures in confined nematic liquid crystal using optical tweezers. Liquid crystal colloids are a novel class of composite materials with well-controlled periodic structures in the nanometer and micrometer ranges. Moreover, they also posses novel mechanical, optical and rheological properties, …

Deuteron nuclear magnetic resonance was used to study the phase separation behavior of photoisomerizable liquid crystal diheptylazobenzene (7AB). Under UV illumination, the elongated trans molecules are converted to boomerang shaped cis form, creating a binary trans-7AB and cis-7AB mixture. It was demonstrated that the concentration of both components can be …

The presence of pharmaceutical residues in surface waters is an emerging environmental issue that provides a new challenge to treatment systems for potable water, wastewater and water reuse. Their principle pathways into the sewerage system are twofold: first, after being administered to patients they are normally excreted as various metabolites …

Behavioural responses are the most efficient thermoregulatory responses, since relatively simple actions can prevent the need to activate the more metabolically costly autonomic responses. Dependence on behavioural responses may increase in environmental conditions where the prevailing nonthermal factors (NTF) attenuate autonomic responses and alter thermal perception (Mekjavic et al., 2003; …
