Reduction of transport loses of volatile form of cadmium for determination by EcHG - in situ trapping - ETAAS
Nováková, Eliška ; Rychlovský, Petr (advisor) ; Červený, Václav (referee)
This thesis deals with possible ways of improving sensitivity and repeatability of determination of cadmium by EcHG - ETAAS. The main complication of this coupled method is condensation of water vapors in the transport capillary, which takes part in the losses of the volatile form of cadmium. Possible solution or at least restriction of the above mentioned problem is heating of the transport route. Experiments also show that reducing the ratio area/volume of transport capillary doesn't lead to reduction of loses of the volatile form of cadmium.

Nutritional Habits of the Pupils of the Selected Primary Schools in Třebíč
POSPÍŠILOVÁ, Lucie
The Diploma Thesis is focused on the nutritional habits of the pupils of the selected primary schools in Třebíč. The nutritional habits and correct diet in children is very important and can be influenced easily. The children are influenced by the family, school, friends and environment they live in, also by the advertisements, especially on TV and the Internet. Correct diet is the one which provides the human organism with the regular and sufficient supply of energy and food. They play a significant role in the healthy growth and development of the organism. Therefore, they are instrumental to keep the condition in the whole life. The diet should be varied and regular. The theoretical part is aimed at delimitation of the characteristics of the school age, description of particular components of the food, importance of drinking routine and the risk of dehydration. Consequently, it describes suitable and unsuitable drinks for children, diet in children and teenagers and related keeping to the regular eating routine and suitability of certain food, principles of the correct diets and food pyramid. The theoretical part pays attention to the kinetic activities, overweight and obesity in children. The practical part brings the results of the research focused on the above issue. The Thesis was elaborated in a quantitative method {--} in the form of questionnaires. The questionnaires were handed round in four primary schools in Třebíč, namely to the eight-class pupils. The monitored set was made up of 208 respondents; 101 girls and 107 boys. In this part, 2 goals and 3 hypotheses were set. The first goal of the Diploma Thesis was to ascertain the diet habits in the second stage of the selected primary schools in Třebíč. The second goal was to record the Body Mass Index of the chosen group of pupils. Hypothesis 1: Eight-class pupils eat insufficient quantity of fruit and vegetables. Hypothesis 1: Eight-class pupils do not keep the drinking routine. Hypothesis 3: Pupils do not have breakfast. Both goals were fulfilled. Hypothesis 1 was rebutted as for fruit consuming. The bulk of the pupils eat fruit every day, in total number of 130 pupils. The second part of the hypothesis was vindicated. The pupils{\crq} board includes vegetables in minimum cases. Only 79 pupils eat vegetables every day. Hypothesis 2 was rebutted. The majority of the informants drink 2 litres of liquids or more. The drinking routine is kept by 135 interviewed pupils. Hypothesis 3 was vindicated. The pupils do not include breakfast in their meals. There are only 93 children who have breakfast regularly. The findings of the Thesis will be offered to schools in question and the interviewed pupils{\crq} parents.

The Use of Chemically Modified Electrodes in Voltammetric Analysis of Nitroaromatic Compounds
Prchal, Vít ; Vyskočil, Vlastimil (advisor) ; Navrátil, Tomáš (referee)
The main objective of this Diploma Thesis is studying the possibility of detection of nitro derivatives of aromatic hydrocarbons by using chemically modified working electrodes in electrochemical analysis. Compounds analyzed in this work were 1-nitronaphthalene and 6- nitrochrysene - these compounds were chosen on previous experience with surface modified working electrodes (the chemical/physical properties of these substances). All the analyses were performed by using differential pulse voltammetry (DPV) on hanging mercury drop electrode (HMDE) in classic three-electrode system. The original premise of chemical modification of electrode surface is the change of its selectivity towards different compounds - meaning the change of the electrochemical response. The modification agent used in this thesis is 1-octanethiol. Its thiol group offers great potential of strong interaction with the metal surface of the mercury electrode. Voltammetric responses of both compounds were recorded in acidic, neutral and basic solutions (pH=2, pH=7, pH=12) including the responses when the electrode surface was modified. Next objective was the optimization of the modification procedure itself (transferring of the mercury drop from one media to another without damaging or tearing it off from the capillary orifice)....

The social roles of HIV positive Tswanas in North West province, Republic of South Africa.
DOBROVOLNÁ, Pavla
In 2006 there were 39.5 million people around the world living with HIV/AIDS, of which more than 63.5% were in sub-Saharan Africa. The number of people infected by the HIV virus in the Republic of South Africa (RSA) in 2005 reached 5.54 million. The prevalence of HIV/AIDS varies in each South African province according to the socio-economic environment. The North West Province (NWP) is one of the nine provinces of RSA. In 2003 the prevalence of HIV/AIDS in NWP was 29.9%. Little attention has been paid to the care and support services for people living with HIV/AIDS. Möller and Petr (2003) proved in their research, entitled ``Health related quality of life, HRQOL, of Tswana in North West Province, RSA{\crqq}, that the quality of life of people living with HIV/AIDS is worse than for the standard population. The aim of this work is, with the use of the HRQOL measuring concept in conjunction with its tool questionnaire SF-36, to determine whether there are any statistically significant differences in the fulfillment of the main social role between HIV positive Tswanas and the Oxford Healthy Life Survey, which is considered to be a standard population. The main social role for 6 out of 8 respondents was the parental one. The fulfillment of this role is negatively influenced by HIV/AIDS, particularly on an emotional level. The secondary aim of this work is to prove whether there are differences in the quality of life between the research group of this thesis, 2007, and the research group of Möller and Petr, 2003. The assessment of HRQOL showed that the quality of life of Tswanas with HIV/AIDS in 2007 is better than in 2003. This might be as a result of respondents{\crq} participation in a support group, as well as respondents working in their community as community health workers. Social contact has proved extremely useful in maintaining a good quality of life. This was also proved by a contact questionnaire, which was attached to the SF-36 questionnaire. The third aim of this thesis is to evaluate the care of people living with HIV/AIDS in RSA, in the period 2003 {--} 2007. The progress of care was determined by the secondary analysis of data, particularly for support groups, Home Community Based Care (HCBC), Voluntary Counselling and Testing (VCT) and anti-retroviral therapy (ART) {--} these support services play a very important role in the care system of people living with HIV/AIDS.

Kaufmannová, Iva ; Nováková, Lucie (advisor) ; Šatínský, Dalibor (referee)
Charles University in Prague, Faculty of Pharmacy in Hradec Králové Department of analytical chemistry Candidate: Iva Kaufmannová Supervisor: PharmDr. Lucie Nováková, Ph.D. Title of Doctoral Thesis: Evaluation of properties of new HILIC stationary phases for pteridins using UHPLC-FD method The subject of this thesis was to evaluate the characteristics of three new types of HILIC stationary phases for the identification and quantification of biologically active substances biopterin, neopterin, dihydrobiopterin and dihydroneopterin by UHPLC with fluorescence detection. Neopterin is used as a marker of immune system activation and inflammatory diseases. Its early detection in urine or plasma may indicate a pathological immune activity. Elevated concentration of neopterin is described in viral or bacterial diseases, in autoimmune diseases in HIV infection or in malignant tumors. 7,8 - dihydroneopterin is able to prevent proteins and lipoproteins from oxidative damage. Hydrophilic Interaction Liquid Chromatography (HILIC) is a chromatographic method that can be used to improve retention of very polar compounds. It uses a polar stationary phase and mobile phase containing a certain amount of water and polar solvents. UHPLC is the most advanced separation technology to develop a pressure of about 100 MPa....

The usage of selected logistic methods in the manufacturing concern
KOHOUTOVÁ, Anna
The main aim of this work was to rate the usage of selected logistic methods and introduction of the operating system Kanban to the production line in the project {\clqq}C214 Top Roll`` of the company Faurecia Automotive Czech Republic, s.r.o, Interior Systems. A minor aim then was to find out the knowledge level of the Kanban method. Methodics Hypotheses: 1.The logistic flows used in the Faurecia company already function sufficiently enough, the proof of which is the stabilised production. 2.Using the operating system Kanban for functioning production, logistics and the whole company Faurecia is rather advantageous. 3.Training all the employees is a vital part in the process of introducing the operating system Kamban. Methods: deducion, situation analysis - collection of information,interviews, survey, questioning brief, modeling Structure of the practical part is following: company profile, character of pruduction and setting of the main logistical flows, determination of zones and stock sectors, process implementation and using of Kanban in the production line "C214 Top Roll". The first hypothesis can be confirmed by the situational analysis which evaluates the processing and logistic method. The individual methods {\clqq}met`` or {\clqq}nearly met`` the demands and because all the methods together partake of the production and the production has provided very good results in the previous months, we can consider the production being stabilised. The second can also be affirmed. If the production on a particular assembly line is stabilised, it is possible to introduce the Kanban method. Why not to use it if a there is a great advantage of this method in simplicity and lower production supplies which result in decreasing the total costs? It is beneficial for all participating on the production and for the Faurecia company as a whole. Third hypothesis can be confirmed as well. There has been a survey based on short questionaires and the knowledge of working and using the Kanban has been found inadequate. The best form of providing all the important information will be a training as a part of the process of introducing and using the Kanban method. Both aims have been resulted in stating possible recommendations and improvement suggestions: - production is stabilized, Kanban is possible to apply on 1.9. 2008 - training is necessary, meeting of responsible persons, control, messing, measures, - training of current and new workers, - motivation, communication improve, - system of regural records about information and control of chief (material and production planning)

Kratochvílová, Petra ; Jeníček, Michal (advisor) ; Královec, Václav (referee)
Land cover changes in Ore mountains and their possible impact on rainfall-runoff process Abstract Land cover changes have occurred since the formation of Earth, but increasingly, these changes mainly in anthropogenic characters, a big problem in many places around the world. It is, therefore, necessary to monitor how land cover changes, and its impact on individual natural processes and use these results of studies in preventing or fix possible consequences of these changes. More and more disciplines are, therefore, also examines this issue. This paper deals with the assessment of land cover change and its impact on rainfall- runoff process, focusing mainly on mountain basin where this influence manifests itself most expressive, both influencing the water balance of the basin, and influence responses to extreme hydrological events. The findings are applied to the upper basin Chomutovka in the Ore mountains where the thesis evaluates changes in land cover on the basis of aerial photos from 1975, 1987 and the present day (2010). Changes are visualized using digital vectorization and color differentiation of areas of individual land cover types, further processed into a map series and subsequently quantified. According to the results are established the major factors of possible rainfall-runoff processes in...

Freedom to contract and its restriction in business obligations
Nedvěd, Filip ; Plíva, Stanislav (advisor) ; Rozehnal, Aleš (referee)
Every law in the Czech legal system regulates social relations. This adjustment serves to protect and determine values in society. Important role in this process hold the basic legal principles. Private law is no exception. Probably the most important principle of private law is the principle of autonomy of will. Its expression in the law of business oblagations is the principle of contractual freedom, which is the main theme of this work. The principle of freedom to contract is quite crucial for the functioning of the modern principle of contract law, which regulates relations arising in a market economy. The aim of this work is to describe the principle of freedom to contract and its manifestation in the legal standards, which governs business obligations. Finally, this work discusses restrictions of freedom to contract, since it is clear that this can not be applied without some correctives. Keywords: contractual freedom restrictions of contractual freedom commercial contractual relations
