The role of material sciences in solving the problems technical accidents
Tonkovič, Miroslav ; Řičánková, Veronika (referee) ; Klakurková, Lenka (advisor)
Material sciences plays an irreplaceable role in explanation of various technical accidents. The proposed work focuses on examples of sever chosen technical accidents in which the knowledge of materials science was crucial in use and help to solve them. Description of an incident is stated to particular cases as well as results of these investigations, taking in mind the given topis of proposed work. The accidents are always described with necessary theoretical basis connected to each particular issue. Its knowledge was undoubtedly essential in solving the accident. The end of the work is a summary of the most frequent causes of technical accidents.

Lithic function and its application in archeology
Krásná, Soňa ; Popelka, Miroslav (advisor) ; Květina, Petr (referee) ; Hroníková, Linda (referee)
The goal of the thesis is to find the way how to apply use-wear analysis as well as functional analysis to archaeological assemblages of selected artefacts from Central European archaeological contexts, namely lithics (chipped stone artefacts) and obtain the greatest potential from the analysis. Thesis consists of: current state in the field of functional studies research worldwide, method of use-wear application in connection with material science knowledge, especially tribology. Use-wear analysis is applied to the selected lithic artefacts from Paleolithic to Eneolithic Periods. The results of this work are based on the following microscopic approaches: low power approach (LPA), high power approach (HPA), scanning electron microscopy (SEM) and confocal laser scanning microscopy (CLSM). There are described and stated differences in potential of above mentioned approaches in connection with specific archaeological artefacts (assemblages of artefacts). The question answered in the conclusion is how to apply the above mentioned methodological approaches in application to various archaeological materials (period, number, context etc.) to obtain the greatest informational potential from the material analysed. Work is concluded with specific terminology from the field of tribology and use-wear analysis...

Content and structure analysis of Czech material science journals abstracts : Hutnické listy and Ceramics-Silikáty
Veselá, Eliška ; Papík, Richard (advisor) ; Kučerová, Helena (referee)
An abstract is a reduced scholarly document crucial for relevant scientific articles and full text documents selection. Therefore abstracts should briefly and clearly represent the full text content. The aim of this research is to construct proper structure, which would be internationally as well as interdisciplinary applied, primarily within the European Union. The structure used in the research was supposed to be evaluated as the most suitable one by the experts. There were 2 material science journals (100 abstracts from each journal) selected. Those samples were analysed in freeware Weft QDA, designed for content analysis of text documents. Sample abstracts were based on the content analysis resulting data. The samples were evaluated by material science experts in the survey. The most common combination of categories in original abstracts were background, methodology and results. The repsonses of surveys pointed out, that the recommended abstract include all necessary information and exclude the redundant ones.
