A bigger than a small quantity of marijuana - for a second time and better? (The perception of the modification of criminal codex by young adults)
Mertová, Simona ; Nekola, Martin (advisor) ; Morávek, Jan (referee)
Simona Mertová, 4. ročník SOSP Abstract The aim of this bachelor thesis was to determine how the young adults, a category of czech population with the highest prevalence of marijuna use, perceive the changes in the domain of cannabinoid drugs in relationship with recent partial decriminalization of marijuana, induced by latest modification of the law number 40/2009 of the law collection. New modification of the criminal code of law got into effect in January 2010 and in my bachelor thesis I examined whether after this date some changes in the behaviour or in the attitudes of the consumers of marijuana occurred. Further, I tested if some changes occured in the attitudes of the young non-users - in such a sense, that they would decide to use marijuana or at least to try this drug. Data and information about consumer's behaviour, attitudes and opinions were investigated by means of semi-structured interviews. The results were gained by the analysis of these interviews. As result of the bachelor thesis there was a determination of an overall impact of the recent modification of criminal code of law, associated with partial decriminalization of marijuana, on the young adults in the Czech republic as well as the determination of potential changes in the behaviour, attitudes and opinions regarding marihuana use as...

Study of laser mixture in the large pressure region
Morávek, Matěj Jan ; Hrachová, Věra (advisor) ; Kudrna, Pavel (referee)
This work studies discharge plasma in a mixture of gases, similar to that used in the so-called CO2-lasers. This mixture consists of CO2, N2 and He. The effect of the mixture composition and discharge parameters (especially pressure, in the range of 266 Pa - 100 kPa) on the distribution of energy in the vibrational levels of nitrogen was examined. This is important parameter for modelling of the discharge plasma. The effect of the mixture composition on the degree of dissociation of the CO2 molecules was also studied. The relative concentration of CO was applied to find the conditions leading to a minimal dissociation of the carbon dioxide. Measurements of radial profiles were also made. Results from two discharge tubes made from different materials were compared. Two types of discharge were utilized to acquire a wide pressure range - low pressure DC glow discharge in the range of 266 Pa to 1330 Pa and dielectric barrier discharge in the range of 5 kPa to 100 kPa. Both discharges are used in commercial CO2-lasers. We observed a descending dependence of the vibrational temperature on the pressure and a big step caused by increased occurrence of standing ionizing waves in the mixtures with low nitrogen ratio. Vibrational temperature in the DBD was markedly lower than in the DC GD, because of the...

Life with HIV/AIDS: A Narrative Construction of Identity
Miott, Jana ; Morávek, Jan (advisor) ; Kotík, Michal (referee)
HIV/AIDS is an illness that is more correlated than any other with high rates of stigmatization and discrimination. People diagnosed with this illness have to cope with a new potentially life threatning situation and stigmatized identity. Common social interactions or heath complications become a potential source of confrontation, which can endanger social relations, or damage and spoil the identity of people living with HIV/AIDS. This study jointly analyzes the concept of social and health risks, stigmatization and identity and focuses on the following: 1) The process of coping with the diagnosis and its impact on the identity and everyday life of people living with HIV/AIDS 2) The role of accessible social networks on the coping process with this illness and stigmatization; and 3) The strategies of health and social risk management used in connection with this illness. Awareness and acquisition of information on HIV/AIDS plays an important role in overcomming the initial shock of the diagnosis and coping with the disease. Thanks to the support of social networks, the diagnosed person can reach much easier and faster the so called "rational approach" to the illness and safely awknowledge and accept HIV/AIDS as a part of his or her life. People living with HIV/AIDS also face many risks. In this...

Influence of the laser mixture composition on the existence of the dinitrogen bands
Morávek, Matěj Jan ; Hrachová, Věra (advisor) ; Kudrna, Pavel (referee)
This project studies mixtures of helium, nitrogen and carbon dioxid, widely used in so called CO2 lasers. These lasers are classified as discharge lasers. In the case of low output lasers is often used a DC glow discharge. We can find bands so called first and second positive systems of a dinitrogen molecule in an emission spectrum of the glow discharge. It is possible to deduce energetic balance and a vibrational temperature from these bands. The vibrational temperature was studied by the vibrational spectroscopy of dinitrogen molecule for various discharge currents and pressures and for various distribution of nitrogen in the mixture (we will start with an industrial mixture LASAL 63).

Typology of regular cannabis users according to level of control
Erva, Jan ; Morávek, Jan (advisor) ; Kotík, Michal (referee)
The thesis examines the patterns of use users maintain and observes their management or self-regulation process. To investigate this phenomenon of (Un)controlled marijuana use: rituals and informal social control in young regular users, qualitative semistructured interviews were conducted with 11 respondents about their use of marijuana. Data analysis was guided by Grounded Theory. Strategies are important in the use of marijuana. Users attempt to cope with risk and prevent social and health problems. They are responsible for monitoring their own use and make decision with regard to their rules, which they ought to abide by. Users consider whether smoking of cannabis could impair them. If their effort is successful, risk will be minimized and control over use will ensue. If users do not abide by internalized rules or even progress to the stage of absence of rules, they will fall into an uncontrolled (chaotic) pattern of use. An entire set of causal and intervening conditions influences the pattern and management of cannabis use.

Water energy potential in breeding tanks
Schittenhelm, Dominik ; Radil, Lukáš (referee) ; Morávek, Jan (advisor)
The thesis is divided in several parts. The first part is theoretical and its main focus is the description of hydroenergy and the theory regarding water turbines and their potential use in small hydro powerplants.The second part describes micro hydroelectric power plant design in fishery Bělidlo. It begins with calculation of the waterflow rate based on the performed measurements. The thesis further describes the actual design of Banki turbine with generator and gear unit selection. The last part of the work deals with estimating construction costs and production of electricity and also of awaiting investment return time.

Identification and detection of defects on the PV system - operational measurement
Leitman, Valentín ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
This work deals with the problem of identifying and detecting faults in photovoltaic systems. This thesis includes theoretical knowledge related to photovoltaic panels, the definition of measured parameters of the PV system and five ways how to identify faults in PV systems. The last part of this bachelor thesis deals with the author's contribution, which is to introduce a system for continuous monitoring data. System for continuous monitoring of data consists of measuring the power output of a photovoltaic panel and measurement using optical diagnostics using thermal camera. In conclusion are summarized individual knowledge, evaluation and recommendation of appropriate measurement methods for the detection of faults in PV systems.
