Application of CAD/CAM technology for production of company logo
Kadlecová, Hana ; Kalivoda, Milan (referee) ; Sedlák, Josef (advisor)
This thesis will address the design and production of the ATC Kolín comapny's logo. Thesis will be supported by the use of CAD/CAM programs. The choice of materials, components and tools will also be specified. Milling strategy will be designed with the PowerMill program. Two different methods of production will be compared. First one is the conventional machining on the FV 25 CNC vertical knee milling plant with the Heidenhain iTNC 530 controlling system. Where as the second one is the additive rapid prototypong technology with the usage of Fused Deposition Modeling method. The thesis is finished by the technical-economic evaluation with analysis and comparison of production alternatives.

Sensory properties of frozen ice creams
KADLECOVÁ, Hana
Low-fat dairy products are gaining its popularity due to the perception of health benefits. However, milk fat plays a significant influence on the structure stability, texture, sensory attributes and appearance. The aim of this diploma thesis was to investigate the potential of using soya as a fat replacer in the development of a low-fat non-dairy ice cream.

English as a Lingua Franca in the Context of the Czech Educational System
Kadlecová, Hana ; Matuchová, Klára (advisor) ; Červinková Poesová, Kristýna (referee)
Despite the predominance of English used by non-native speakers in international communication, the approach to teaching this language is still centred on the notion of acquiring English for the purpose of communication with native speakers. This thesis argues for acknowledgement of English as a lingua franca in the approach to teaching English. It also stresses the necessity of further investigations into the global use of English to better understand this phenomenon. A questionnaire was conducted with ten English teachers to see their opinions about some of the key issues of English as a lingua franca (for instance the concept of nativeness, the role of a teacher and the understanding of an error). As a result, it was found that despite some slow changes in individual opinions, the traditional view on teaching English is still prevalent. Both the theoretical research and the analysis of the questionnaire stress the need of implementing the concept of English as a lingua franca into teaching English as it is necessary to prepare students for the reality of global use of this language. Key words: English as a lingua franca, second language acquisition, nativeness, error, variation

Seasonal variation of the territorial behaviour of the European beaver (Castor fiber L.).
Kadlecová, Hana ; Horáček, Ivan (advisor) ; Červený, Jaroslav (referee)
The presented thesis deals with the temporal and spatial changes in activity of the European beaver (Castor fiber L.) during different seasons. Basic dataset was obtained by continuous telemetric monitoring of selected individuals in years 2008 and 2009 in two different geographical areas, namely in the Bohemian forest and in southern Moravia. The scope of the thesis was to record, evaluate and interpret the behavior of European beaver during the year. I focused myself especially on the beginning and end of activity in relation to incidence of sunrise and sunset, duration of stay in the field, changes in the size of actively-used area and time-duration and length of the movement. In cases where there were more active individuals monitored within the studied area, I also watched for their mutual interaction. In statistical analysis of gained data I also took into account the sex and age of the individuals. Beaver's behavior varies during the year. They are most active in spring and autumn, while in winter their activity decreases significantly. This observation is valid not only for the time duration and length of movement trajectories, but also for the size of actively-used area. The beginning of activity is strongly correlated with the sunset, while the end does not show any correlation with...

Toxic substances in food and their effects to human health
KADLECOVÁ, Hana
The bachelor thesis "Toxic substances and their effects to human health" deals with characteristics of selected historical periods of toxicology. It describes the basic concepts of toxicology. It briefly characterizes toxic substances of plant and animal origin. More attention is paid to mycotoxins, especially aflatoxins, fumonisins, ochratoxins and zearaleon. A very important part of this thesis is the prevention of the effects of toxic substances on human health and describes the partial measures that are necessary before consumption or preparing of food. The practical part examines the awareness of university students about important toxic substances in food. It assesses whether these students recognize the desired mold species on food. Next it is interested in what precautionary measures are taken by university students before consuming and preparing food. The conclusion of the thesis shows that the know-how of university students is relatively high.
