Evaluation of local filler sources suitability for anhydrite-based screeds
Šikral, Martin ; Kaláb, Michal (referee) ; Drochytka, Rostislav (advisor)
Goal of this thesis is to evaluate suitability of local filler sources for anhydrite based screed floor covers. The theoretical part is mostly aimed at summarization of general findings about flooring constructions and about anhydrite itself. The thesis also includes description of primary and secondary raw materials. The goal of this work is to suggest suitable fillers for anhydrite based screed floor covers in accordance with distance from Sika CZ, s.r.o with residence in Brno – Modrice. At the same time this thesis explores possibility of secondary raw materials usage as a replacement of primary fillers. In conclusion the thesis focuses on the laboratory test of chosen fillers, summarization and discussion of discovered findings.

Determination of climbing specific maximal oxygen uptake during climbing with increasing inclination and constant speed

Title of master thesis Determination of climbing specific maximal oxygen uptake during climbing with increasing inclination and constant speed. Work objectives To review the determination of climbing specific maximal oxygen uptake during climbing with increasing inclination and constant speed. Methods Twenty six climbers with climbing ability on UIAA scale from 4th to 10th degree were participated in this study. Maximal specific oxygen uptake was measured by climbing test, to exhaustion on climbing wall, where the inclination were changed from 95ř (105ř) to 135ř every three minutes. Speed of climbing was constant on 25 movements·min-1 . After a rest, the participants went a maximal running test on treadmill. There were evaluated relationships between climbing ability, inclination and cardiopulmonary variables. Results In maximal climbing test, climbers achived plato on value 40 ± 3,5 ml·kg-1 ·min-1 , without influence on climbing ability or inclination. The climbing ability most corelated with achived inclination r = 0,89 and heart rate r = 0,41. Our study confirmed disproportional rising of heart rate against oxygen uptake. Furthermore, there was a strong relationship to be found between ventilation per 1l oxygen to RER indicating specific breathing mechanism of advanced climbers. More demanding...
