This master thesis deals with inhalation of fine particles and fibres into human lungs. This is a scientific field where computer modelling is used to describe the movement of fibres and their deposition in the lungs. However, the results of these simulations must be verified experimentally. The prediction of fibres behaviour is important from a toxicology point of view where it is important to know deposition hot-spots and places where fibres could possibly cause problems. The review of the state-of-the-art is focused on the deposition of particles in human lungs followed with a chapter on fibre as a type of particle, and occupational exposure limits set by different world associations. The last theoretical chapter describes human lungs and its diseases which can evolve when limits for occupational exposure are not met. The experimental chapter consists of a description of the used experimental setup and results from an experiment together with a comparison of results with other similar experiments.

Student prezentoval svoji DP práci. Byly přečteny posudky vedoucího a oponenta a položeny otázky oponenta. Student zodpověděl dotazy oponenta. V rozpravě k DP byly položeny studentovi tyto otázky: prof. Jícha se dotázal jak byl určen charakteristický rozměr (průměr) při výpočtu Stokesova čísla? prof. Jedelský se dotázal proč nebylo uvažováno s působením elektrostatických sil? prof. Jedelský se zeptal jaký je rozdíl mezi usazováním vláken a kulových částic? Student zodpověděl všechny dotazy.
