Design of vibrating waste sorter
Taska, Abraham ; Tůma, Zdeněk (referee) ; Synek, Miloš (advisor)
The master thesis deals with a construction proposal for a vibrating sorter of cartridges. The thesis contains the theoretical part characterizing various sorter types of cartridges and describes the principle of sorting with the help of the vibrating sorters. The practical part includes a draft of a drive, calculation of a vibrating sorter, a proposal of compression springs bearing vibration frame and a control calculation of these springs. A complete vibrating sorter of the cartridges is created in a 3D modeling program. The thesis is attached by the drawings of the individual assemblies, subassemblies and individual parts.

Conception of terrain vehicles UTV
Máca, Jiří ; Vopařil, Jan (referee) ; Kučera, Pavel (advisor)
This review type bachelor thesis is dealing with conceptual solutions of Utility terrain vehicles. Individual chapters are describing main functional groups and different options of their construction. These options are analysed in terms of suitability for given application in utility and sport terrain vehicles, their manufacturing complexity and costs. Specific vehicles are mentioned only marginally.

Suggestion of tumbling machine's construction
Matula, Petr ; Bilík, Martin (referee) ; Synek, Miloš (advisor)
The master´s thesis deals with a suggestion of vibratory tumbling machine´s construction for tumbling of brass cartridges. The thesis contains theoretical part which describes the principle of tumbling and its possibility of using, further characterizes various types of tumbling machines and their parts. Practical part of thesis includes functional calculations of vibratory tumbling machines, draft of power, compression springs bearing tumbling container and control calculation of these springs. Complete tumbling machine is created in a 3D modeling program. Drawing documentation which includes individual drawings of assemblies, secondary assemblies and their particular parts according to task is enclosed.

The study of water quality in springs and wells in Křivoklátsko area.
Brabenec, Tomáš ; Benešová, Libuše (advisor) ; Popovský, Jiří (referee)
At present, the nature around us is constantly being polluted by anthropogenic activities; therefore the quality of all components of the environment, including water must be monitored. This thesis examines mainly the water quality in selected springs and wells in the Protected Landscape Area of Křivoklátsko. For individual wells is shown in what environment they are and even some history. Several locations were tipped off where water sampling was carried out, and in the laboratory the basic physico-chemical parameters were defined. In conclusion of this thesis, are the individual wells and springs included in water quality classes according to CSN 75 7221. It is shown that monitored parameters have exceeded limits and whether the water in a well and spring is drinking or not.

The springs of the radioactive medicinal groundwaters in the Chrastava - Bogatynia area
Černík, Tomáš ; Goliáš, Viktor (advisor) ; Vylita, Tomáš (referee)
A radiogeochemical exploration in the area of Chrastava - Bogatynia belonging into lugic region was conducted in the years 2012 - 2013. This exploration's objective was to search for and investigate radioactive water manifestations with radioactivity concentration reaching minimal value of 1500 Bq/l 222Rn. This boundary is set in the spa law no. 164/2001 Sb. as a minimal radioactivity concentration for radioactive mineral water. In this area, 30 water manifestations were discovered meeting the boudary of >1500 Bq/l 222Rn. The most significant cluster is located in Albrechtice by Frýdlant. Close to Kančí vrch (Boar Hill) 12 radioactive water springs were discovered. In the town of Albrechtice, a discovery of dissolved salts- rich radioactive mineral water was made, concerning springs Soumar and Matka. The most mineralized spring Soumar contains more than 1 g/l of dissolved salts (hydrochemical type Na-Ca-Cl water with total mineralization up to 1,5 g/l) combined with it's 222Rn activity surpassing 1500 Bq/l. Another significant cluster is located near the town of Nová Ves by Chrastava, where the most active source of the whole area, Mikulášský pramen (Mikulash Spring), with activity up to 2821 Bq/l 222Rn, was found. Another three radioactive water springs were found in this area. Also, probable dry...

Are springs safe? Effect of water quality on public health.
PETROUŠKOVÁ, Zuzana
Bachelor thesis aims at water quality in eleven springs and wells usually considered as a source of drinking water with superior quality exceeding the quality of drinking water from municipal sources. Springs and wells were monitored for one year and microbial, physical and chemical parameters were determined according to the Czech authorities' requirements. Microbial contamination was recorded in eleven cases mostly during dry summer. Thus dry hydrological conditions should be considered as a critical factor for water quality. Chemical parameters were exceeded in nitrate concentration at one site, probably due to agriculture in spring catchment. Water quality exceeded required values in 64%, thus the required frequency of water quality monitoring is not sufficient and water quality could exceed requirements during parts of a year.
