Design of Electric Suction Pump
Šrůtková, Markéta ; Sládek, Josef (referee) ; Rubínová, Dana (advisor)
The assignment of this bachelor’s final thesis is the design of electric suction pump. The main goal is to design a device with adjustable vacuum for people of all age groups, a stable attachment of the secretion container, a suitable place storage space for tubing and innovative elements. The work is based on the current state of knowledge of existing products and their arrangement. The design takes into account technical and ergonomic requirements. The final product will be used mainly by rescuers of integrated rescue systems.

Moisture characteristics of natural sandstone exposures
Slavík, Martin ; Bruthans, Jiří (advisor) ; Tesař, Miroslav (referee) ; Sněhota, Michal (referee)
Moisture in a sandstone body plays a notable role in hydrological, weathering, biological and other processes. Knowledge about presence and movement of moisture within porous medium of natural sandstone exposures is, however, rather limited. Aim of the doctoral thesis was thus to quantify selected moisture characteristics of several natural sandstone exposures in Český ráj (Czech Republic). According to long-term logging, mean annual temperature at studied areas was between 8.5 řC to 11.5 řC, mean annual relative humidity was between 73 % to 85 %. Deforested area was found warmer and drier and amplitude of the values was higher there than at the forested areas. Values of water content (more than 400 measurements) and suction (more than 150 measurements) of the exposures including their spatial-temporal changes were obtained. Mean volumetric water content in zone from the sandstone's surface to 12 cm depth was from 3 % to 10 % and mean suction in depth 2-12 cm was from 2 kPa to more than 130 kPa. Using uranine powder coloring, spatial distribution of moisture near the sandstone's surface was visualized repeatedly for the first time. The coloring divided the surficial area of the sandstone into capillary (wet) and diffusion (dry) zone. The sharp transition between the two zones was represented by...
