Závodní úzkost u sportovních gymnastek: Vztah k věku a délce sportovní kariéry / Competitive anxiety in female gymnasts: Association with age and length of sports career

Lipšanová, Tereza January 2021 (has links)
Title: Competitive anxiety in female gymnasts: Association with age and length of sports career Objectives: The main aim of the diploma thesis is to describe levels of competitive anxiety and its association to age and length of sports career in young female gymnasts from Prague. Methods: The thesis has a character of empirical and theoretical research and includes elements of quantitative research with an application of a survey. Specifically the thesis represents a cross-sectional study. A multidimensional questionnaire, the Competitive state anxiety investory-2 was administered to a sample of N = 18 female gymnasts. The questionnaire consists of three subscales measuring: somatic anxiety, cognitive anxiety, self-confidence. Data were analyzed using basic descriptive statistics, and the Pearson correlation coefficient was used to examine the hypotheses about relationships. Results: The results have shown that age is related to somatic and cognitive anxiety, whereas both components of competitive anxiety increase with increasing age. On the other hand age was not associated with self- confidence. The length of sports career was positively associated with somatic anxiety and self-confidence, however was not related to cognitive anxiety. Keywords: activation, emotions, cognitive anxiety, somatic...

Výzkum šetření energiemi v domácnosti ve světle teorie plánovaného chování a modelu aktivovaných norem / An Examination of Household Energy Conservation Behavior in the Framework of Theory of Planned Behavior and Norm Activation Model: Prague Case

Boyaci, Çagatay January 2021 (has links)
This M.A. thesis aims at investigating the socio-psychological motivations and demographic factors related to how individuals perform energy conservation behavior in the household domain. For this reason, two approaches to this sociological issue, the Theory of Planned Behavior and Norm Activation Model, were comprehensively examined to be adequately combined into one experimental model that would determine and help to explain the motivations on the energy conservation behaviors in households. In total, 303 respondents were surveyed who have a residency in Prague by sharing an online-based questionnaire in various Facebook groups between April 28, 2021, and July 3, 2021. In order to test the created hypotheses according to the developed model of the research study, structural equation modeling and ANOVA analysis were employed. As a result, the findings show that combining the Theory of Planned Behavior and the Norm Activation Model gives promising results in explaining the socio-psychological motivations of household energy conservation behaviors. The author of the thesis concludes that social norms have a positive influence on personal norms, and further the personal norms have a positive impact on intentions, and therefore the intentions directly impact the household energy conservation behavior....

Rehabilitace historického jádra a přilehlého okolí města Kyjov se zaměřením na veřejný prostor / The Rehabilitation of the historical center and adjacent surroundings of Kyjov with a focus on the public space

Kratochvilová, Jana January 2018 (has links)
The diploma thesis deals with the construction and activation of the territory in connection with the historical center of Kyjov. Part of the proposal was to work with an existing urban brownfield and an extensive park, which accounts for almost half the area under consideration. The goal, as I set out in my work, is to activate the territory and design an urban sprawl with a suitable functional structure. The proposed design respects the context and character of the site in a modern and sustainable manner. The principles followed in my work are based on the current urban and city-forming rules. I have put an emphasis on the human scale, the priority of pedestrians over traffic, and especially the shortcomings and needs in the territory that arise from the analysis. The draft concept is based on the permeability and interconnection of the individual parts of the city, the insertion of a new public space and the completion of the city block. The new urban sprawl clearly defines the street, completes the boundaries and makes the most of the area on the released land. The newly designed buildings are residential and multi-functional houses with active parterres. Part of the proposal is the revitalization of the city park, which explores its hidden potential. The basic step is to remove obstacles in the permeability of the park and to highlight its strengths, such as the flowing river Kyjovka, healthy large trees and the size of the park itself.

Účinek zvýšené koncentrace oxidu uhličitého na množství a aktivitu enzymu Rubisco / Impact of elevated carbon dioxide concentration on the Rubisco amount and activity.

Zachová, Lucie January 2008 (has links)
In this diploma work changes of initial and total activities and content of Rubisco in beech and Norway spruce were studied. The plants were cultivated in conditions with ambient CO2 concentration (350 mol·mol–1) and elevated CO2 concentration (700 mol·mol–1). Three series of samples (at the beginning, in the middle and at the end of growing season) were taken. Initial and total Rubisco activities were measured spectrophotometrically and activation state was calculated. Rubisco content was determined by SDS–PAGE method. Rubisco activity in beech cultivated in elevated CO2 concentration decreased during the whole growing season while in beech growing in ambient CO2 concentration Rubisco activity decreased up to middle of growing season and then increased. Rubisco content in beech in ambient CO2 concentration slightly increased and in beech in elevated CO2 concentration decreased up to middle of growing season and then increased. Rubisco activities in Norway spruce both in ambient and elevated CO2 concentration decreased. Rubisco content in Norway spruce in ambient CO2 concentration decreased but in Norway spruce in elevated CO2 concentration first decreased and then increased.

Solik, Jaroslav January 2012 (has links)
This thesis explores the posibility of using of foundry filter ash for production of inorganic composite materials, that could be used primary in the construction industry. The thesis is divided into theoretical and experimental section, where theoretical section contain literature review of used materials and the experimental section summarizes the results of laboratory tests performed on tested mixture based on portland and alumina cement with various content of foundry filter ash. For comparison was also used another foundry waste - foundry sand. Prepared test bodies with dimension of 40 x 40x 160 mm was subjected to mechanical strength tests and the influence of amount of foundry waste on the strenght of the prepared mixtures was monitored. Next the thesis deals with possibilities of alkaline activation of foundry waste, where sodium water glass, sodium hydroxide and commercially supplied baucis L 160 component B were used as alkaline activator. These test mixtures were also subjected to mechanical strenght tests and the influence of amount of foundry waste on the strenght was observed too. The analysis of input materials were performed by XRF, TG – DTA – EGA and XRD powder diffraction methods. All strength tests were tested by testing equipment desttest 4310.

Fosfátové konverzní povlaky / Phosphate conversion coatings

Ševčíková, Barbora January 2012 (has links)
The main objective of the master’s thesis is to study the influence of phosphate coating structure on the mechanical properties of screw connection. The theoretical part describes the conventional phosphating process and it is followed by an analysis of current knowledge of phosphating technology. Experiments are carried out on screw valves mounted to a high pressure diesel pump by Bosch Diesel s.r.o., made of unalloyed carbon steel. To investigate the effect of the structure on the connection sealing, twelve kinds of phosphate coatings varying in one process parameter were prepared. The monitored parameters determining the phosphate structure are – type of phosphate and activation bath, its temperature and concentration and time of immersion. The sealing connection is examined during simulated assembly process by angle controlled tightening while measuring torque and permanent material deformation. Prepared layers are characterized by determination of weight per unit area and their structure observed by electron microscope.
