Noise, Transport and Structural Properties of High Energy Radiation Detectors Based on CdTe
Šik, Ondřej ; Lazar, Josef (referee) ; Navrátil, Vladislav (referee) ; Grmela, Lubomír (advisor)
Poptávka ze strany vesmírného výzkumu, zdravotnictví a bezpečnostního průmyslu způsobila v posledních letech zvýšený zájem o vývoj materiálů pro detekci a zobrazování vysokoenergetického záření. CdTe a jeho slitina CdZnTe. jsou polovodiče umožnují detekci záření o energiích v rozsahu 10 keV až 500 keV. Šířka zakázaného pásma u CdTe / CdZnTe je 1.46 -1.6 eV, což umožňuje produkci krystalů o vysoké rezistivitě (10^10-10^11 cm), která je dostačující pro použití CdTe / CdZnTe při pokojové teplotě. V mé práci byly zkoumány detektory CdTe/CdZnTe v různých stádiích jejich poruchovosti. Byly použity velmi kvalitní spektroskopické detektory, materiál s nižší rezistivitou a výraznou polarizací, detektory s asymetrií elektrických parametrů kontaktů a teplotně degenerované vzorky. Z výsledků analýzy nízkofrekvenčního šumu je patrný obecný závěr, že zvýšená koncentrace defektů způsobí změnu povahy původně monotónního spektra typu 1/f na spektrum s výrazným vlivem generačně-rekombinačních procesů. Další výrazná vlastnost degenerovaných detektorů a detektorů nižší kvality je nárůst spektrální hustoty šumu typu 1/f se vzrůstajícím napájecím napětí se směrnicí výrazně vyšší než 2. Strukturální a chemické analýzy poukázaly, že teplotní generace detektorů způsobuje difuzi kovu použitého při kontaktování a stopových prvků hlouběji do objemu krystalu. Část mé práce je věnována modifikaci povrchu svazkem argonových iontů a jejímu vlivu na chemické složení a morfologii povrchu.

Vývoj metodologické a technologické platformy pro neinvazivní odhad fenolických látek v listech a bobulích
ŠEBELA, David
Plant optical signals can serve as important source of information about biochemical and physiological processes in plants. These signals are influenced by compounds synthesized by plants during primary or secondary metabolism and thus, can also serve as their qualitative and quantitative indicators. Light reaching plant surface (leaf or fruit) can undergo three main pathways- it can be (i) reflected, (ii) absorbed or it can (iii) transmit through plant material. The probability of these three processes depends on particular wavelength of incident irradiation and on the morphological characteristics of plant tissues themselves. As such, plant contains various spectrum of photosynthetic pigments and fluorescent compounds which can either reflect, absorb or pass incident irradiation through at specific wavelengths. Biophysical techniques working with these optical properties of plant pigments and/or other compounds have become universal and common tool in basic and applied research. To quote some example, chlorophyll fluorescence imaging, UV induced fluorescence or spectroscopic techniques are on the top of interest thanks to its non-invasive nature, allowing maintain the integrity of measured cells or the whole plant constituents. The main aim of this thesis is to provide a comprehensive study on the possibility of non-invasive monitoring of phenolic compounds in the leaves and fruits.

On Motivation of Moravian and Silesian Anoikonyms Derivate from the Appellative kámen
Šimečková, Marta
This paper deals with motivation of Moravian and Silesian minor place names containing the basic noun kámen ‚stone‘, e. g. Kameňák (the suffix -ák was attached to the respective noun to create this anoikonym), Kamenice (with the suffix -ice), Kamenička (with the suffix -ička). There are numerous motivations, the most frequent is the motivation of soil quality and of location (especially in prepositional anoikonyms, for example Mezi kamencem, Na kamenici). Other motivations are rare: motivation of a particular stone as significant part of the landscape, motivation of building material or stone mining. The frequency of these motivations is different from the frequency of motivations in underived anoikonyms (or anoikonyms containing plural form of the fundamental word Kameny; in this type of anoikonyms, motivation by a particular stone in the site is more frequent). The motivation is hard to determine in some cases, the interpretation can be impeded by bachelor's etymology therefore it is necessary to cooperate with old maps.

Organization and management of production in selected enterprise
DRNOVÁ, Markéta
The topic of my dissertation is "Organization and management of production in selected enterprise". The main goal of this dissertation is mapping of selected enterprise in one year period and obtain sufficient amount of information for future analysis and suggest possible improvements. The identification data, characteristic, products and services and production planning of selected enterprise are provided in introduction of practical part of this dissertation. Analysis of present state with mapping of present state for individually semi-finished products is introduced in the next part of dissertation. For analysis of present state was calculated VA index and for each semi-finished product was created diagram of material movement in next chapter. The goal of analyses and diagram is the finding of narrow spaces in the material flow. The target map of future state was created in the next part. This map is based on present map. The future map presents critical factors that need to be improved. Finally it defines a new VA index, which should be approach to the current state. The penultimate section includes recommendations methods and elements of lean production to the new production hall which the company wants to build. Among the recommended methods are mainly the 5S method, visualization, standardization, SMED and Bottleneck. The last chapter contains a number of measures. For example employee motivation, continuous improvement, personal responsibility, introduction of EDI and ergonomics which would lead to the improvement of the business this enterprise.

History of critical and intensive care - past and present
HOVORKOVÁ, Nicole
The title of the bachelor thesis is "History of critical and intensive care - past and present". Its main aim is to describe its origins in order to explore the history of providing critical and intensive care, both in the Czech Republic and in a global context, and also in comparison to the current state of the medical field. This work is focused on the period of development of intensive care, from the 50s to the 80s. It is a theoretical work done by detailed research of secondary and primary sources. It is divided into two parts. The first is dedicated to intensive care and its global development and in the Czech Republic. The second part contains data about intensive care within the hospitals of South Bohemia, which I have gathered during the study of materials provided by the local archives. The first chapter and the second chapter is dedicated to the history of nursing, both worldwide and in the Czech Republic. It serves for better orientation in the next chapter. The third chapter deals with intensive care itself. It is described in many of its aspects and in its historical and global context. The fourth chapter brings us to the second part of the thesis, which is supplemented with information from archival materials found during the research in regional archives. The thesis includes some photos that were captured either during a visit to the Museum of the National Medical Library, or during visits to the archives.

Assistance as compensatory and supporting means of the special pedagogy
PÝCHOVÁ, Lucie
My Bachelor thesis is focused on the topic of "Assistance as a compensation and support to special pedagogy". The aim of my bachelor thesis is to complete theoretical knowledge related to the assistance phenomenon and to analyse the occupation of personal assistant. The aim of practical part of my bachelor thesis is to implement the comparison of legislative determination and provable working activities carried out by pedagogical and personal assistant. In accordance with the aimes specified above has been established two partial aims. 1st aim: to examine what the assistants´ work motivation is. 2nd aim: to examine the level of assistants´ self contentment.Thesis is devided into two parts theoretical and practical one.Theoretical part is devided into three units. First unit defines the key words: assistance, compensation and support, special pedagogy, social integration and inclusion. Second unit is focused on personal assistance itself. Related key words are defined as well. In this unit I also describe a historical development of the personal assistance process, working demands placed on potential assistant, possible complications related to mentioned occupation and of course everyday work routine. Third unit is focused on the personality of assistant and assistants themselves. I describe the historici development of the assistants´ personality, work requirements, work duty and cooperation with parents and educational institutions. Practical part contains the specification of work aims, methodology of investigation, related data gathering process and of course the data analysis. I interviewed pedagogical assistants just as the personal ones. All the data and results contained in my bachelor thesis can be used for needs of any related organisation recruiting new assistants, because it contains informations which could be useful when hiring people. My thesis can be also used as a background material for any further students.
