Car dependence in Czechia: the example of municipalities with extended power Černošice and Kralovice
Dvořáček, Jan ; Marada, Miroslav (advisor) ; Zevl, Jiří-Jakub (referee)
Car dependence is a problem that has been closely linked to transport and land use planning since the mass spread of motoring in the second half of the 20th century. Excessive or total dependence on the car has many negative impacts, especially environmental and social ones. The aim of the study was to investigate the extent of car dependence in the Czech Republic in selected areas representing typical problem areas (periphery and suburbia), to identify and characterize the most dependent places in them. For this purpose, a network analysis of public transport accessibility carried out using a transport model of pedestrian accessibility in a GIS environment and the calculation of an indicator of car dependence were used. The results show that in the Czech environment in the study areas, the problem is more strongly related to small, mostly without the status of independent municipality rather than suburban neighbourhoods, which are most frequently mentioned in the Anglo-American literature. A very poor situation was also identified in what were formerly purely recreational second homes, but which are now partly permanently inhabited. Key words: car dependence, public transport, mobility, network analysis

Attitudes of physical education teachers to combat sports
Dvořáček, Jan ; Pavelka, Radim (advisor) ; Venzara, Jan (referee)
Title: Attitudes of physical education teachers in martial arts Goals: To find out the perspective of teachers in the martial arts, what is their relation to this problematic and if they would agree to include these activities in physical education program. Methods: This is an empirical research, which will be used method of questioning by questionnaire. Results: Results indicate what sports teachers think about combat sports and show if teachers attitude to these activities is rather positive or negative and why. Key words: Attitudes, teachers, martial arts

Sildenafil má rozsáhlé neuroprotektivní účinky při malonátem navozeném poškození striata potkana
Dvořáček, Jan ; Pourová, Jana (advisor) ; Nachtigal, Petr (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Pharmacology & Toxicology Student: Jan Dvořáček Supervisor: Prof. Norberto Aguirre, PharmDr. Jana Pourová, Ph.D. Title of diploma thesis: Sildenafil causes a large neuroprotection against malonate-induced lesion of the rat striatum. The aim of this thesis was to investigate the neuroprotective effects of sildenafil (PDE-5 inhibitor) and of the substance SB203580 (p38 MAP kinase inhibitor). Both substances provided significant protection against malonate-induced lesions in the rat striatum. The results showed that the protective effects of sildenafil are not related to any effect on ROS production. The model of malonate-induced lesions was examined as well. The Bax levels remained unchanged in both the mitochondria and cytosol in the malonate-treated rats. Similarly, no changes in cytochrome c levels were observed.

Possibilities of using cold gas dynamic spray (Cold Spray) in military applications
Dvořáček, Jan ; Štěpánek, Roman (referee) ; Řehořek, Lukáš (advisor)
This work aims to acquaint with thermal spray method called Cold spray. This method is used for repair of expensive and badly replaceable components, which are mainly used in aerospace and military branch of industry. These repairs cause economic savings, higher accuracy and quality than other thermal spray methods. There is a possibility to use Cold spray for ballistic armor production. It is possible that ballistic protection would have higher ballistic efficiency, durability and coherence. The second part of the work handle with the evaluation of the interface of a metal-ceramic two-layer ballistic protection system made by the cold spray method. The evaluation was performed in the form of light and electron microscopy.

Dispersion studies for logistic problems
Dvořáček, Jan ; Šomplák, Radovan (referee) ; Pavlas, Martin (advisor)
Presented diploma thesis deals with the application of dispersion modelling of emissions from stationary sources of pollution as a potential tool which can be used for data preparation in reverse logistic models. In this case, the stationary source is represented by a waste-to-energy plant. The thesis consists of two main parts -- theoretical and computational. Firstly, emission sources and pollutants originating in thermal waste treatment are discussed. In the second chapter, legislation linked to the problem of air pollution is listed and the topics of current air quality in the Czech Republic and dispersion studies are outlined. Closing section of the theoretical part provides information about the principals of dispersion calculations and classification of dispersion models is given. In the computational part, the used dispersion software SYMOS'97 is introduced and the series of conducted calculations is presented. The calculations investigated the influence of plant capacity, dispersion conditions and terrain on the results. The input data of plant capacity and wind rose were indicated as key parameters in the calculation. The final evaluation revealed a good potential of the used dispersion model as a support tool in reverse logistic models.
