Design of Handheld Anemometer
Valentová, Radka ; Rubínová, Dana (referee) ; Sládek, Josef (advisor)
This bachelor thesis deals with the design of a handheld anemometer. The main issues addressed are the ease of operation during use, the shaping for a more secure but ergonomic grip, the coherence of the shape of the anemometer in relation to the propeller and other parts. The design should meet both ergonomic and aesthetic requirements. The overall design of the shaping of the product is simple and functional. The handheld anemometer has a wide range of applications and can be used in other sectors besides sports and recreational activities.

Analysis of some active substances in different products from rice
Valentová, Radka ; Melounová, Jitka (referee) ; Márová, Ivana (advisor)
Presented diploma thesis is focused on analysis of selected biologically active substances in different kinds of natural and peeled rice. In rice samples phenolic compounds, antioxidant activity, content of saccharides and vitamin C were analysed. Active substances and saccharides were analysed by UV-VIS spectrophotometry and RP-HPLC-UV/VIS. Content of phenolic compounds and saccharides was measured before and after acid hydrolysis. The content of these compounds increased several times because of release of active substances from glycosides. As a part of diploma thesis basic sensory analysis was performed and consumer questionnaires were evaluated. The highest level of antioxidant activity was detected in Indian Wild rice. The highest content of total polyphenols and flavonoids was detected in Red Rice Natural before acid hydrolysis. After acid hydrolysis the highest content was detected in Indian Wild rice. The highest content of individual flavonoids, phenolic acids and catechins was detected in natural rice Indian Wild, Rice Three colours and in two samples of rice parboiled. The highest content of total and reducing saccharides was found in rice Indian Wild before hydrolysis, while after hydrolysis the content was very similar in all rice samples. The amount of individual monosaccharides after acid hydrolysis increased, while total content of disaccharides decreased. The highest value of simple sugars was detected in rice parboiled and Indian Wild rice. The content of vitamin C was detected only in four rice kinds - in two samples of rice parboiled, Rice Three colours and rice Indian Wild.

Analysis of biologically active substances in some cereal products
Valentová, Radka ; Starečková, Terezie (referee) ; Márová, Ivana (advisor)
Presented bachelor thesis is focused on study of biologically active substances in cereal products. In theoretical part over view of cereal active substances, predominantly phenolic compounds were introduced. In practical part 15 kinds of cereal products were analyzed. In these materials some group parameters - total phenolics, total flavonoids and total antioxidant activity were measured by spectrophotometry. RP-HPLC/UV-VIS method was performed for analysis of selected individual flavonids. The highest content of phenolic compounds was measured in cereals containing fruits (raspberries, blueberries, tropical and red fruit), cacao, crusty fruits (hazel nuts, sunflower seeds) and buckwheat. All cereal products contain catechine, epicatechine, catechin gallate, epicatechin gallate, chlorogenic and ferulic acid. As a part of bachelor thesis simple sensory analysis was performed and consumer questionnaires were evaluated.

Current streams in marriage and parenthood education
Valentová, Radka ; Lorenzová, Jitka (advisor) ; Pelikán, Jiří (referee)
This thesis is concemed with current streams in marriage and parenthood education within the framework of curricula existing in the Czech Republic and the nowadays shifts in public attitudes towards marriage and parenthood. The thesis outlives legal consequences of marriage, conditions essential for entering and dissolving marriage - concluded either at the registry or at church. The thesis reflects also up on the recently adopted law on gay marriage as another acknowledged form of cohabitation. Data confirmed by statistics provide a picture of the first marriage and birth rates. Outlines are given of a specific project designed for education aiming at mature marriage decision making and healthy and responsible parenthood. The concluding part contains samples of current literature on the given topic plus their assessment.
