Multi-filament yarns testing for textile-reinforced concrete
Kaděrová, Jana ; Seitl,, Stanislav (referee) ; Vořechovský, Miroslav (advisor)
The scope of the presented master thesis was the experimental study of multi-filament yarns made of AR-glass and used for textile-reinforced concrete. The behavior under the tensile loading was investigated by laboratory tests. A high number of yarn specimens (over 300) of six different lengths (from 1 cm to 74 cm) was tested to obtain statistically significant data which were subsequently corrected and statistically processed. The numerical model of the multi-filament bundle was studied and applied for prediction of the yarn performance and for later results interpretation. The model of n parallel filaments describes the behavior of a bundle with varying parameters representing different sources of disorder of the response and provides the qualitative information about the influence of their randomization on the overall bundle response. The aim of the carried experiment was to validate the model presumptions and to identify the model parameters to fit the real load-displacement curves. Unfortunately, due to unsuccessful correction of measured displacements devalued by additional non-linear contribution of the unstiff experiment device the load-displacement diagrams were not applicable to model parameters identification. The statistical evaluation was carried only for the maximal load values and the effect of the specimen size (length) on its strength was demonstrated. The size effect curve did not exclude the existence of spatial correlation of material mechanical properties modifying the classical statistical Weibull theory.

Arc optical diagnostics
Čermák, Jiří ; Valenta, Jiří (referee) ; Dohnal, Petr (advisor)
The aim of this bachelor thesis is to sort out the individual types of electric discharges, explain the ionization inside the plazma of the electric arc and the elucidation of the energetic balance inside the plazma. The electric arc is an undesirable and hardly predictable phenomenon occurring in switching devices during switching on and switching off the electric circuit. Some older methods of image processing obtained by a high-speed camera are also mentioned. Based on the images obtained from the camera, it is possible to make an equidensity or an equidensitogram that is used to monitor the arc in a quenching chamber. The second part includes the description of an experiment performed in a laboratory and the description of the high-speed camera used during this experiment. A modern method of the image processing using software Matlab is also described. An equidensitogram showing different levels of radioation was made in Matlab from the obtained images.

Vliv malolaktické fermentace na aromatický profil červeného vína
Veselý, Radek
This master's thesis is specifically concerned with the influence of malolactic fermentation on the aromatic profile of red wine. The literary (theoretical) part defines the malolactic fermentation and describes the volatile substances formed during malolactic fermentation. The practical part results from an experiment of various kinds of malolactic fermentation, where there are used two different strains of lactic acid bacteria. The experiment was carried out on three different varieties of wines which were sensorically and analytically evaluated.

The content of the selected science textbooks with regard to the use of methods of direct study of nature
VÁCHOVÁ, Pavlína
The main scope of the thesis is the analysis of four chosen sets of science textbooks, which is focused on discovery of frequency of tasks, which use the methods of strict studies of nature. The discovered tasks are closely classified from the perspective of thought operations severity, which must be known by pupils to be able to solve the tasks. This classification was defined by Tollingerová and is also mentioned by Kalhous and Obst (2002). In the last part of the analysis, the given tasks are classified by levels of inquiry as it is mentioned by Banchi and Bell (2008). In the framework of this thesis, four tasks, which are targeted to the methods of strict studies of nature, from which one was tested on the pupils during the practise, were devised.

Plants as model organisms in inquiry science education in primary education
JINDROVÁ, Aneta
Research-oriented teaching is an attractive way of teching (not only) science subjects. At the first stage of primary school, it is an opportunity for developing students' research abilities. Plants are a suitable subject with which simple experiments, observations and research activities can be performed. The aim of the work is not only to find the possibility of using plant material in students' science research during teaching, but also to evaluate how research activities are accepted by students, how they are able to solve problems and how creative they are in solving research tasks. The work should show the possibilities of combining standard tasks based on plant observation with tasks based on different levels of research activity. The diploma thesis is divided into a theoretical and a practical part. I approached this thesis in four steps. In the first step the curriculum and content of selected textbooks are analyzed with a focus on the issue of learning about living nature, in the second step the educational offer is presented, in the next step the proposed educational offer is verified with simultaneous monitoring and analysis of students 'research tasks and pupils' creativity. In the last step, the results of the survey are evaluated and the obtained data are interpreted. The diploma was drawn up as part of a project GAJU 123/2019/S.

Legal regulation of animal testing The diploma thesis is analyzing current legislation in the field of animal experiments. It is formed by five chapters and each chapter is concerned with different aspects of animal protection, when focusing on experimental animals in particular. The first chapter is divided into three subchapters and it is successively describing development of animal experiments, progress of legislation dealing with animal protection and experimental animal protection on the international and European level, when analyzed is also Czech legislation in the last subchapter. Second chapter is focused on the basic legal sources and its legal foundation. It has four subchapters, when every subchapter explains relevant terms, which are being formulated in the experimental animal protection law. This chapter of the diploma thesis also involves sections dedicated to experiments and alternative methods of the experiments. Following chapter of the thesis (chapter nr. 3) describes legislation of the experimental animal protection and it is constituted by three subchapters, which are regarding ensuring expertness of the experiments, farming of and caring for the experimental animals and also approving, progress and finishing the process of the experiment. Every subchapter is then divided into...

Vogalová, Naděžda ; Böhm, Pavel (advisor) ; Žilavý, Peter (referee)
The aim of this thesis is to summarize already published tutorials for experiments with the Vernier lab system and to write new tutorials respecting requirements and specifics of the Czech educational system. Six new detailed tutorials were prepared. All of them were, or would be, published on the Internet web site of The Framework Education Programmes (www.rvp.cz). Following tutorials were written: Bulb flickering, Warm-up of a compact fluorescent lamp, Relation between illumination and distance of the light source, Relation between illumination and number of filters, Why is salt used in the winter on the roads, Photochromic glasses. Each experiment is accompanied by a classification with respect to The Framework Education Programmes and by requirements for The State High School Leaving Exam (``maturita'').
