Evaluation of the safety of the transport of dangerous goods by road
NĚMEC, Tomáš
The theoretical part approaches the topics connected with the transport of dangerous goods and associated topics, for example, from the development of legislation relating to the transport of dangerous goods from the time of the Austrian empire and the First Czechoslovak Republic through the current legislation, e. g. domestic and international validity, and also an important document - the agreement of the ADR, on which the legal rules are based. The next part of the thesis is concerns hazardous substances, including the description of their classification and identification. The following section, which deals with the characteristics of the transport of dangerous goods, including training of persons carrying dangerous goods, the obligations of the participants with transportation from the point of view of safety. An important part of the transport of dangerous goods is also documentation. The three basic documents are: transport document, safety data sheet and the written instructions for the driver. The theoretical part of the thesis deals with the following: the requirements regarding the properties on gear road vehicles that transport dangerous goods; the activities of the occupants of the vehicle, if an accident occurs or the emergency situation and the related release of hazardous substances; traffic restrictions, such as restrictions on the transit of vehicles carrying dangerous goods in road tunnels. Conclusion of the theoretical part deals with the principles of the behavior of the population in case of accidents with leakage of hazardous substances and related improvised protection of individuals. These principles build on the models of situations with leaks of hazardous substances that are listed as part of the results. The aim of this thesis is to determine compliance with the legislation on the transport of dangerous goods by road. For setting the goals there are two research questions, namely: How much are traffic regulations being broken? Which regulation of the transport of dangerous goods by road is being broken most often? To determine the answers to the research questions we chose a survey using the questionnaire survey focused predominantly on the driver transporting dangerous goods by road. In the thesis, respectively, the research included a total of 100 valid questionnaires. In the questionnaire survey all of the respondents were randomly chosen, however, some of them refused to answer some questions. The survey revealed that infringement in the field of transport occurs in a fairly small range. The selected eighteen provisions in the legislation, which were violated in varying degrees, were most often replied by the drivers that they never met with the violation of the regulation (together marked 825 times, expressed in % 45,83 % of the total), exceptionally (together marked 782 times, expressed in % 43,44 % of the total), regularly (together indicated by 181 times, expressed in % 10,06 % of the total) or always (together identified 12 times, expressed in percent of the 0.67% of the total). The questionnaire survey also revealed that violations of regulation of the smoking ban is most often. Out of 100 respondents, 30 answered that they met with a violation of this regulation regularly (26) or always (4). Among the other most frequently infringed legal regulations in the field of transport include the rules in securing the cargo to the loading area, where 19 respondents out of 100 answered that they met with a violation of this regulation regularly or always. The rules concerning the manipulation with dangerous goods during the course of loading and unloading, it was noted that 19 of the respondents met with a violation of this regulation regularly (17) or always (2). There are also the results of modeling accidents in the program of the Terrorist Expert TerEx.

Violence and aggression in healthcare professionals with a focus on workplace of acute psychiatric care
Němec, Tomáš ; Jirkovský, Daniel (advisor) ; Haluzíková, Jana (referee)
The aim of the bachelor thesis was to provide basic information on aggressiveness at selected workplaces of Bohnice Psychiatric Hospital. In the framework of this work, a questionnaire was submitted to 194 respondents performing general nurses or health care professions, acute care departments and subsequent psychiatric, anti-toxic and gerontopsychiatric care. The investigation took place during December 2016 and January 2017. The main results showed that respondents from PN Bohnice encounter high frequencies with aggressive patients, i.e. daily or weekly in 60% of cases. Most respondents (92%) encountered verbal and physical aggression. The most common kind of physical aggression is the destruction of property (52%), the assault of a health care professional (40%) and self-harm (39%). The most common type of aggressor is male (50%) and female (44%), less frequent visits and the patient's family (3%). For men, physical aggression is higher than for women by more than 13%. According to medical professionals, the most common cause of aggression is the disease (67%), fear and anxiety (32%), and the third is environment (27%). Physicians deal with conflicting situations most often by appointment (97%), and secondly in cooperation with other health workers, i.e. they call service (55%) or doctor (44%)....

Consistency of empirical corrections of the classical nucleation theory for nucleation in steam with nucleation experiments and molecular simulations
Hrubý, Jan ; Duška, Michal ; Němec, Tomáš ; Kolovratník, M.
We compare experimental nucleation rates for water vapour in various carrier gases, nucleation rates deduced from empirical adjustments of the classical nucleation theory (CNT) earlier developed to reproduce pressure and optical data for condensing steam flows in converging-diverging nozzles and turbine stages, and ucleation rates obtained from molecular simulations. Results of original molecular dynamic simulations for TIP4P/2005 force field in the NVE conditions are provided. New experimental nucleation rate data sets are generated based on empirical CNT corrections by Valha and Nedbal (1980) and by Petr and Kolovratník (2011). Correction of the CNT for non-isothermal nucleation conditions is applied to experimental, simulated and the derived experimental data. The derived experimental\nnucleation rate data follow a similar temperature trend as the nucleation rate data for water vapour in carrier gases at lower temperatures. The ratio of observed nucleation rates to CNT predictions decreases more steeply with temperature than the empirical correction by Wölk et al. (2002). Ratios of nucleation rates computed from molecular simulations to CNT predictions do not show a significant temperature trend.

Mutual comparison of the appointment of judges in Czech Republic and on the basis of the merit system.
Němec, Tomáš ; Antoš, Marek (advisor) ; Kudrna, Jan (referee)
Mutual comparison of the appointment of judges in Czech Republic and on the basis of the merit system The diploma thesis deals with a comparison of the appointment of judges in the Czech Republic and an appointment of judges based on merit system. The aim is to describe in detail both systems and determine whether the application of the principles of a model example of the appointment of judges based on merit systemis possible to apply in the Czech Republic. In the first chapter I set the basic assumptions of a judge that any judge should meet. Using these assumptions I also compare both systems the appointment of judges. The ideal system for appointing judges, in my opinion, should be set so that on its basis were appointed judges who are independent and impartial, accountable, trustworthy, intelligent and have the necessary experience and moral assumptions. The second chapter is devoted to the current system of appointment of judges in the Czech Republic, where I describe the current legislation and appointment of judges that deal with the process that precedes the appointment of judges by the President. At the end of the second chapter I summarize how the current system for selecting judges take into account the criteria mentioned in the first chapter. In the third chapter I present system of...

Termodynamická analýza procesů v palivových článcích s pevnými oxidy
Vágner, Petr ; Maršík, František (advisor) ; Némec, Tomáš (referee)
The fuel cells are the technology of the future. Although their discovery dates back to the 19th century the nature of how they work hasnt been adequately explained so far. This thesis focuses on description of solid oxides fuel cells (SOFC) for which ion conductive electrolyte and high operating temperature are distinctive. The mathematical model of SOFC developed in this thesis is formulated in terms of the mixture theory. The model development was constrained and simplified by isothermality, time-stationery and 1D approximation. The model equations characterize gas and ion transport and electric current flow in the fuel cell. Eventually comparison of the thesis model equations with the SOEC (solid oxides electrolysis cell) model developed at the Institute of Chemical Technology in Prague showed that both approaches lead to a similar conclusion. This thesis can be used as a basis for an experimental verification of the mixture theory. 1

Marketing strategy of the company 3M in social media
Němec, Tomáš ; Halík, Jaroslav (advisor) ; Luňáčková, Michaela (referee)
Diploma thesis focus on social media as a phenomenon of modern times and their use in a marketing. I will introduce four most frequently used social media - Facebook, Instagram, Twitter and YouTube as well as an outline the possibility of their use in marketing. Marketing strategy in social media I decided to introduce through a concrete example - an international company 3M. This company I chose mainly because it operates in the market of industrial products, where online marketing is not as much used and also because it cooperates with University of Economics. After introducing the basic marketing theories and explanations of basic terms I will analyze an existing 3M marketing strategy in social media and on the basis of the analysis and obtained data I will suggest my own possible marketing strategy for the company 3M, which connects all the aforementioned social media.

The history of industrial accidents with hazardous materials in today's Czech Republic
NĚMEC, Tomáš
This thesis is divided into two main parts. The first theoretical part includes for example the introduction to valid legal regulations concerning chemical accidents. The second part includes the obtained results, which are presented in two separate subchapters. The first charter is about the most serious accidents. In less serious accidents such a loss of human life have been eliminated. This part is divided into two categories: industrial accidents that occurred up to 2000 and accidents after 2000. This thesis includes also a tabular overview of some industrial accidents.
