Differentiation and crystallization of evolved granitic melts, the Říčany pluton, central Bohemian Massif
Jandová, Tereza ; Dolejš, David (advisor) ; René, Miloš (referee)
Evolved silicic rocks display a variety of igneous textures, which can provide important information on crystallization kinetics and rheology in natural magma chambers. Individual kinetic effects such as diffusion rate, nucleation rate, growth rate and post-solidification modifications are likely to be reflected in the modal and textural appearance of the resulting rock. This work focuses on characterization and interpretation of solidification textures in a 600 m wide and 5 km long body of highly evolved, boron-rich aplites and pegmatites at the southern endocontact of the Říčany granite pluton (Central Bohemian Plutonic Complex). This rock suite is associated with biotite Říčany granite, hosting microgranite and aplite dyke swarm, and it is built up by massive tourmaline aplites, layered aplites with tourmaline-rich or locally garnet-rich bands, pegmatite pockets, pegmatite layers with unidirectional solidification textures (comb layers), megacryst zones (analogous to stockscheider), and late pegmatite dykes discordant to layering. Textural as well as modal variations are usually sharp and observable megascopically as well as on the microscale. All aplites and pegmatites usually contain similar proportions of quartz, albite-rich plagioclase, K-feldspar, various proportions of tourmaline (up to...

Hydrodynamic and thermal mode ling of reactive flow in the surroundings of intrusions
Jandová, Tereza ; Dolejš, David (advisor) ; Bruthans, Jiří (referee)
English Summary Intrusion of magma into the Earth's crust is associated with significant thermal perturbations, release of aqeuous fluids and formation of hydrothermal system. In order to better understand the feedback relationships between fluid flow, thermal evolution and permeability variations, we have modeled conductive and advective cooling of a shallow- crustal pluton using the SHEMAT software. Our model represents a two-dimensional cross section through the lithosphere with homogeneous material properties, whebery the heat and mass conservation equations are solved by finite difference method. We first calculate the stable lithospheric geotherm by emplying constant basal thermal flow of 40 mW m-2 and a constant surface temperature. Subsequently, we consider a rectangular magmatic intrusion emplaced at 5-10 km depth, which forms a contact aureole by conductive cooling. With time, a mushroom-like shape of the contact aureole is predicted. Inclusion of aqueous fluid flow into the model causes only a small alteration of thermal evolution mainly because the permeability is low and the fluid mass is negligible due to very low density under hydrothermal conditions. In addition to thermal effects, we have explored variations in hydraulic head in order to address the ensuing effects on the flow velocity. The...

Possibilities and Limits of Care in Childern's Homes and a Model of a Possible Alternative
Jandová, Tereza ; Rotreklová, Eva (advisor) ; Šmídová, Olga (referee)
This thesis concerns the problems connected with the legal protection of children in the Czech Republic. In particular it focuses on possibilities of taking care of children who are forced to live out of the family. All contemporary possibilities how to care about such children as well as legislative of these amenities are surveyed and financial system of these is introduced. Based on background professional research, the most common reasons for placing children out of their own families are presented. Work and function of homes for children are described in further details. The theoretical part offers the view into historical development of taking care of Czech children without any stable and functioning family background, some good experience examples from France and samples of endeavour to remedy the situation in Slovakia are mentioned. The inner part of the thesis is the issue concerning not only wide variety of psychological theories but also the satisfaction of children development needs. Research part traces fulfilling children development needs in a particular children home taking into consideration the point of view of the staff, the parents whose children were placed there and the youngsters who were cared about. According to the latter and the research summary, a model of children care...

The effect of smoking and alcohol consumption on tooth decay and periodontitis in adults and the relationship between alcohol intake and visceral fat in the older adults
Vlasáková, Jana ; Šteffl, Michal (advisor) ; Jandová, Tereza (referee)
Title: The effect of cigarette smoking and alcohol consumption on dental caries and periodontitis in adults and the relationship between alcohol intake and visceral fat in the elderly. Objectives: The aim of my master thesis was to assess the influence of alcoholic beverages and cigarette smoking on the risk of dental caries and periodontitis in adults. Another aim was to assess the relationship between alcohol intake and visceral fat in the elderly. Methods: The thesis is carried out as two independent cross-sectional studies. In the first study, gender differences were tested using the non-parametric Kolmogorov- Smirnov test. Pearson's correlation coefficient was used to assess the relationship between the amount of alcohol consumed in kg and cigarettes smoked in pcs and the risk of dental caries or periodontitis. In the second study, body composition analysis was performed using the electrical bioimpedance method. Two-sample Kolmogorov-Smirnov test was used to test the hypotheses. In addition, a dot plot depicting the relationship between the amount of alcohol and visceral fat was created. Results: A total of 18 respondents took part in the first study, a survey. The results showed a high statistically significant correlation between the consumption of alcoholic beverages and the risk of dental...

Utilization of nutritional supplements at elite athletes
Teclová, Julie ; Coufalová, Klára (advisor) ; Jandová, Tereza (referee)
Title: Utilization of nutritional supplements at elite athletes Objectives: The aim of the bachelor's thesis was to determine the character and current trends in the use of nutritional supplements by the top athletes in various sports. The partial goal was to compare the results of the use of nutritional supplements and to develop feedback for individual companies selling sports supplements. Methods: A questionnaire survey was used to collect data, containing open and closed questions regarding the use of nutritional supplements. It also contained questions in what form athletes use supplements, the main reasons for use, at what frequency and what are the preferred brands of supplements. The survey was sent in electronic form to 33 respondents who practice top-level sports in the Czech Republic. Results: It was found that all the surveyed individuals take nutritional supplements. By the endurance athletes, the claim that they prefer supplements with an excitatory effect in combination with supplements leading to weight reduction has been confirmed. It was also proven that more than 50 % of respondents prefer a particular brand of nutritional supplements and do not plan to change it, and more than 50 % of athletes surveyed use supplementation daily. It was also found that elite athletes prefer the...

The use of food supplements by amateur athletes in the fitness
Lukeš, Jan ; Coufalová, Klára (advisor) ; Jandová, Tereza (referee)
Title: The use of food supplements by amateur athletes in the fitness Objectives: The objective of this work is to find out the use of specific food supplements by amateur athletes in the fitness. Methods: Data were obtained through quantitative research, which was conducted through electronic questioning on the platform Survio.com. Subsequently, a statistical evaluation of collected information was performed. Results: The evaluation of the data obtained from the questionnaire survey showed, that 86 % (111) of respondents use food supplements, for up to 4 of them without any side effects. The use of food supplements is bigger by men than by women. Regeneration support, improving sports performance and building muscle mass are the most common motives for using food supplements. On the other hand, respondents who do not use food supplemets claim, that they do not need them. For respondents, the best sources for obtaining information are the professional literature and the internet. The internet is also the best source for acquisition of food supplements. The most commonly used food supplements are protein products, vitamins and minerals, primarily from the Extrifit brand. Key words: Nutritional supplementation, sport, fitness

Dynamics of Everyday Life in Dialogue with Emmanuel Lévinas
Jandová, Tereza ; Sokol, Jan (advisor) ; Bierhanzl, Jan (referee) ; Novotný, Karel (referee)
The main objective of this research is to look at the topic of everyday life from a dynamic perspective. The definition of everyday life that this thesis stands upon, i.e. the presence of a subject in the world with the other(s) outlines also two main sources of its dynamics: the world and the other. The essential aim of this thesis is to show that the different attitudes towards the world and the other in the works of Husserl and Lévinas consequently influence the understanding of the everyday life as such, as well as the requirements it imposes upon the subject. The chapter dedicated to Husserl presents his concept of the world as a horizon, the irreplaceable position of perception in our access to the world and the creation of the other within the subject itself. On the contrary, Lévinas stresses the separation of the subject and he understands the world and the other as inherently belonging to this never-ending process. The motive of dependence and responsibility of the subject for the other belongs to the most significant differences between the two philosophers. Whereas Husserl proposes us a subject in the world which he accesses via perception and in which he encounters the other, Lévinas shows us subject that is born to the pre-reflexive and intersubjective world from which he first has to...

Short-term cryotherapy effects to ankle proprioception
Huotari, Tiina ; Tufano, James (advisor) ; Jandová, Tereza (referee)
The purpose of this study is to determine the effect of short-time cold pack cryotherapy in thermoreceptors, therefore, proprioception via deep sensation receptors and sense of balance on ankle joint in healthy adults. In the subject, I refer to other studies using the word proprioception when measuring the cold effect in the balance of the ankle joint. Mainly, cold therapy is affecting to the thermoreceptors but there might be input also to change neuromuscular transmission. The aim of the experimental process is to identify if the cold application on the ankle joint for 20 minutes is decreasing dynamic postural stability and the sense of balance in laboratory environment. Short term cryotherapy effect is measured within 12 participants divided into two groups: control and study group. Both groups went through the first measurement, 20 minutes rest with or without cold application and second measurement directly after the rest period. The dynamic posturography machine SMART Balance Master System (NeuroCom) was used to evaluate somatosensory outcome in the experiment. In the systematic review the previous studies are investigated within same settings as on experimental process, short time cold application on ankle joint measuring the effect on ankle proprioception and joint position sense. The...

Self-medication with alcohol among menopausal and postmenopauzal women
Jandová, Tereza ; Kuda, Aleš (advisor) ; Richterová-Těmínová, Martina (referee)
The bachelor thesis deals with the self-medication theory among menopausal and postmenopausal women. It is divided into a theoretical and practical part. The theoretical part presents self-medication theory and important studies exploring self-medication of mood and anxiety disorders, health effects of alcohol consumption on women, psychosocial aspects of menopause and higher prevalence of mood and anxiety disordes among menopausal and postmenopausal women. The practical part presents qualitative research with case studies exploring alcohol addiction in three perimenopausal women. Case studies are also focused on their psychological condition, drinking motives and perimenopausal symptoms. Questionnaire battery and semi-structured interview were used for data collection. The aim was to describe self-medication phenomenon among menopausal and postmenopausal women and start the debate for another research. The research claims that alcohol consumption among perimenopausal women was rising as the psychological condition was getting worse to cope their negative emotions. The research demonstrates diversity of possible self- medication among menopausal and postmenopausal women as every woman describes different psychological problems, menopause experience and alcohol using. Due to large number of...
