The incidence of suicidal behavior among drug addicts.
SKOŘEPOVÁ, Lucie
This diploma thesis on the theme: The incidence of suicidal behaviour among drug addicts in the theoretical part deals with the development of the drug scene in the Czech Republic, the EU drugs policy in the Czech Republic, selected studies dealing with drug use, health and social consequences of drug use. Also deals with suicide behaviour, its forms, types, methods and causes of suicidal behaviour, motivation, development of data collection and the treatment of suicidal behaviour. The aim of this work was to find out the most common reasons and ways of suicidal behaviour in addicts individuals in the psychiatric hospital of the Cerveny Dvur (hereinafter referred to as PH CD ). Another objective was to determine whether the clients have undergone a treatment PH CD after the suicide attempt. On the basis of the objectives have been created three research questions. Due to the nature of the investigated problem was as a research method chosen semi- structured interview with clients. Before the research was carried out in PH CD questionnaire survey on suicidal behavior for a team project GA JU No. 103/2013/S "The effect of systematic psychotherapy tailored to the incidence of intentional self-injurious behaviour".. Based on the data from the questionnaire investigation were clients selected for this diploma thesis. Interviews were conducted with eight clients of PH CD.

HYDROGENATION PROPERTIES OF BALL-MILLED Mg-Ti-C-Zr COMPOSITE
Král, Lubomír ; Čermák, Jiří ; Roupcová, Pavla
The hydrogen storage properties of ball-milled Mg-Ti-Zr-C composite (1.8 wt.% Ti, 1.9 wt.% Zr and 0.2 wt.% C) were investigated. It has been previously shown, that the addition of Ti, Zr and C improved its storage properties. This beneficial effect of additives upon hydrogen storage properties can be explained by catalysis by the particles rich in Ti or Zr located on the surface of Mg grains. They provide effective pathways for the hydrogen diffusion into the MgH2. The morphological and microstructural characteristics were investigated by scanning electron microscopy and by X-ray diffraction. The hydrogen sorption was measured by Sieverts method using Setaram PCT-Pro device. In this paper, sorption behaviour of the composite after ball-milling and after aging on the air was compared. The ball-milled composite adsorbed 3.5 wt.% H2 within 10 min at 623 K. However, hydrogen storage capacity of the composite aged on the air for 7 months remarkably decreased: The aged composite adsorbed within 10 min only 2 wt.% H2 at 623 K and the sorption capacity decreased from 4.7 wt.% H2 to 2.1 wt.% H2.

Changes in structure and phase composition in the surface of tram rail
Švábenská, Eva ; Roupcová, Pavla ; Schneeweiss, Oldřich
We have investigated structure and phase composition of surface layer of tram rails after long time running and the results were compared with those obtained on the original part of material. Changes due to effects of severe plastic deformation together with thermal shocks by friction process were expected. The information about structure and phase composition was obtained by optical and scanning electron microscopy, X-Ray Powder Diffraction, Mössbauer Spectroscopy and Glow Discharge Emission Spectroscopy (GDOES) and this was completed by microhardness measurements. The results show that the surface layer in comparison with the original material exhibits important changes in grain structure, an increase in microhardness and high content of iron oxide and hydrooxides. According to the depth profile of the chemical composition measured by GDOES there is an increase in carbon content in the surface layer which can be effect of up-hill diffusion.

Fluidized-bed Combustion of Dry Stabilized Sewage Sludge in Oxy-fuel Mode
Moško, Jaroslav ; Pohořelý, Michael ; Durda, Tomáš ; Zach, Boleslav ; Šyc, Michal ; Svoboda, Karel
Sewage sludge is an inevitable waste stream from wastewater treatment and its disposal is complicated due to specific characteristics of its composition. Sewage sludge combustion/incineration is the only suitable way for disposal of large volumes of sewage sludge containing POPs and some heavy metals. Sewage sludge combustion reduces the volume of such waste and causes destruction of organic contaminants. Oxy-fuel combustion is a technology for simplifying CO2 sequestration from the flue gas by using nearly pure oxygen instead of air for the combustion. In order to control the combustion temperature, part of the flue gas is recycled to combustion chamber. The paper brings information about investigation of the effects of combustion temperature and concentration of oxygen in inlet combustion media on the emissions of NOx, N2O and SO2 in FB combustion of sewage sludge. The experimental results have shown that an increase in combustion temperature leads to an increase in NOx and to a decrease in N2O emissions in the temperature range 750–930 °C. The lowest SO2 emissions were measured in the temperature interval from 800 to 820 °C in all experiments with different oxygen concentration in inlet gas. It was found that when the oxygen concentration in inlet gas increased, the emissions of SO2 increased while emissions of NOx slightly decreased.

NUMERICAL ESTIMATION OF MICRO-CRACK PATHS IN POLYMER PARTICULATE COMPOSITE
Majer, Z. ; Náhlík, Luboš
Determination of composite mechanical behavior is one of important part during the composite tailoring. The aim of the present work was to estimate a micro-crack behavior in a polymer particulate composite. The composite was investigated by means of the finite element method -using ANSYS software. A two-dimensional three-phase finite element model was developed to analyze the crack growth behavior. The assumptions of the linear elastic fracture mechanics were considered and the Maximum Tangential Stress (MTS) criterion was used to predict the direction of the crack propagation. The effect of the elastic modulus of the interphase on the micro-crack propagation was investigated. The properties of matrix and particles were taken from experiment. It was shown that the interphase properties influence the stress intensity factor KI as well as the micro-crack paths. The results of this paper can contribute to a better understanding of the micro-crack propagation in particulate composites with respect to the interphase.

Age management
Jirásková, Barbora ; Dvořák, Marek (advisor)
This thesis processes the concept of the human resources management with respect to the age structure of employees in the intentions of the Czech Republic. In the theoretical part, there is outlined the history of the application of the principle of age management, focusing on current demographic trends, forecasts of population age structure, the aging workforce and the need to preserve the ability to work into old age. Points to the need to adapt corporate strategy, personnel management trend of an aging population. It presents ideas for the main underlying programs and legislative measures which form the basis of the latest concepts and strategic plans in the Czech Republic and Europe. The empirical part deals with a specific level of allowance organization established by TSU and two sub investigation. The first is a case study of age management staff. The resulting data are confronted with the results of a survey among employees of the organization. The second investigation are interviews with members of management and employees of the HR department on the issue of the introduction of age management, their awareness of the concept of age management, the question of age discrimination, the issue of maintaining the continuity of knowledge in the organization and their views on these topics. The outcome of this survey indicates a willingness and readiness of the organization has already received age management principles adhere to and develop further.

Microbiota of the digestive tract of bees and related insect and the influencing facftors
Hroncová, Zuzana ; Havlík, Jaroslav (advisor) ; Kalous, Lukáš (referee)
This thesis consists of six research chapters, out of which, five have already been published in research journals, 1 is in the process of submission and the last chapter presents original unpublished confidential data in the process of manuscript preparation.
The research presented in this thesis concerns the complex mechanisms of bees and wasps immune system focused on microbiota as component of immunity. As shown in the introduction, highly social and managed species of bees like honey bees and bumble bees, play key roles in natural and agricultural ecosystems worldwide. Recent losses of bees have been attributed to pesticide exposure, poor nutrition, increased parasite loads and habitat degradation. Over the past several years, governments, beekeepers, and the general public worldwide have become concerned by increased losses of honey bee colonies, calling for more research on how to keep colonies healthy. Our main aim was to explore the complex mechanisms of bees and related species gut bacterial populations, their links to insect immunity and investigate the opportunities for an intervention. Part of our aim was to characterise the bumble bee and wasp gut microbiota using 16S RNA sequencing in a search for potentially novel bacterial species.
We have tried to explain how microbiome interacts with the host and showed that major members of these communities appear to benefit the host. The simple gut communities of social bees present ideal model systems to investigate the underlying evolutionary and genetic processes of such interactions. Information based on our results may help in the design of proper probiotic supplementation strategies with respect to physiological conditions in the honey bee gut.
