The use of bioimpedance analysis for kidney function evaluation
Veselková, Alena ; Šrámek, Petr (advisor) ; Švára, František (referee)
Objective: To calculate glomerular filtration (GF) through the use six available methods to estimate GF and measure impedance parameters phase angle () and fat free mass (FFM) by using multifrequency and monofrequency measurement. Select one method of estimating GF as a strict method of estimation GF for this study and by using linear regression relate with other method of estimating GF and impedance parameters measured () and FFM. Consider if () and FFM are significant parameters to improve methods of estimating GF given below (MDRD-A, MDRD-B, CLCG, CLcysC). (...) Conclusions: Impedance parameters () and FFM correlate with GF, decreasing GF cause decreasing of these impedance parameters. This study proved very close relationship between parameters FFMx and FFMc, obtained by using two different kinds of measuring (R2 - FFMx and FFMc = 0,843). Method of bioimpedance is ready to other validation and to develope bioimpedance scale to estimate renal function.

Study of the synthesis and structure of ceramic perovskite materials for energy applications
Strejček, Josef ; Bartoníčková, Eva (referee) ; Cihlář, Jaroslav (advisor)
Method, so called “glycin- nitrate process”, combined with high temperature solid state reaction, of preparation multi- component ceramic perovskite materials was studied. Two types of perovskite systems were prepared by this method. Firs one, based on LaNiO3 doped by calcium and aluminium and second one, based on SmFeO3 doped by calcium and nickel or cobalt. This method made possible preparation of one phase perovskite or perovskites with few percent of nickel in form of oxide. In systems containing both nickel and calcium another phases rich in calcium and nickel appeared.

The chosen validation parameters of method for assessment of aroma compounds in elderberries
Christovová, Silvia ; Ürgeová, Eva (referee) ; Vítová, Eva (advisor)
This bachelor thesis deals with the assessment of aroma active compounds in elderberries (Sambucus nigra L.). In the theoretical part the chemical composition and attributes of elderberries are described. Brief information on their healing properties is also given. The possible processing methods in food industry, as well as the traditional means of use at home, are discussed furthermore. Following chapters describe the gas chromatography method combined with the technique of solid-phase microextraction, utilized for the specification of aroma active compounds. The validation of this method is also included. The aim of the experimental part of the work was to verify a set of the selected validation parameters of the SPME-GC method, specifically linearity, the limits of detection (LOD), the limits of quantification (LOQ) and repeatability. Subsequently, the SPME-GC method was applied on the chosen elderberry juice samples. In total, 37 different volatile aroma active compounds were identified and quantified, 15 of which belonged to alcohols, 9 to aldehydes, 5 to ketones, 5 to esters and 2 other compounds. The chemical composition of individual samples was not uniform; no single sample contained all of the identified compounds.

Analysis of Iron-Phosphorus Reaction Products Formation During Heat Treatment Processes
Skoumalová, Zuzana ; Jan, Vít (referee) ; Doležal, Pavel (advisor)
During high pressure pulsation tests repeated cracks of CP3. housings occur. High pressure pump CP3 is part of injection system Common Rail. Cracks can be caused by segregation of phosphorous from a washing medium on grain boundaries during subsequent heat treatment process. The present master´s thesis focuses on analysis of phosphorous compounds on specimen surface made from steel 20MnCr5, which were soaked in solutions with different concentration of phosphorous. Master’s thesis is also focused on potencial influence of phosphorous on structure and properties of this material. The first part of the thesis provides a summary of current knowledge in the studied field, experimental results can be found in the second part. The surface analysis XPS, the light microscopy, the scanning electron microscopy equipped by energy dispersive chemical analysis, the glow discharge optical emission spectroscopy, the methods of the phase analysis by means of the X-ray diffraction and impact test were used.

Diagnosis of game performance in football
Štumpf, Bedřich ; Buzek, Mario (advisor) ; Tůma, Martin (referee)
Title: Diagnostics ofgame performance in football. Goal ofthe project: To analyze the style of resolving the quick counter attack ofCzech Republic at the under 20 years World Championship in football. To localize the constructive gain ofthe ball with resulting utilization offree spaces for carrying out the counter attack. To note (activity analysis) all attacking actions endíng with a shot, standard situations gaining or dangerous scoring chances. Method: Observation analysis with quantitative and qualitative ranking indirect sighting. Results: Objectification oftheoretical approaches in activity structure in match process in football. Application approaches for utilization in training process in the sense ofmatch and training integration. Keywords: Quick counter attack, football, constructive gain ofthe ball, application approaches 2

Preparation issues of teen-agers between the ages of 16-18 years
Smejkal, Jaroslav ; Buzek, Mario (advisor) ; Bošanský, Jiří (referee)
TITLE Preparation issues ofteen-agers between the ages of 16 - 18 years GOAL OF THE WORK The goals of my work were to outline the training model in the Czech Republic, monitoring of players complex effort of FC Victoria Pilsen, next the detection of negatives in game activities in matches and suggestion the training steps to removing realized negatives. METHODS Research was realized by direct and indirect observation methods, mainly using DVD records of teenagers 1st match. There were used qualitative and quantitative analyses of game activities. RESULTS Analysis should reveal some new facts. Results should define requirements for improvement oftechnical and tactical maturity ofindividua! in activities. KEYWORDS Game effort, qualitative and quantitative analysis, errors solution 3

Optical properties of the GaN on sapphire
Skalský, Miroslav ; Janta, Jiří ; Čtyroký, Jiří ; Stejskal, J. ; Hüttel, I.
The method of mode spectroscopy was used to measure optical properties of epitaxial layers of gallium nitride (GaN) deposited onto the sapphire substrate. The results of the measurement of the layer thickness, refractive indices, and the attenuation of guided modes at the wavelengths of 632.8 nm and 781 nm are presented. From experimental values of attenuation of different guided modes, the contributions of bulk absorption and scattering at the interfaces of the layer to the total optical loss in the waveguide are determined.

Phase-correlation based image registration
Druckmüllerová, Hana ; Martišek, Dalibor (referee) ; Procházková, Jana (advisor)
Tato práce se zabývá použitím fázové korelace k určení vzájemné rotace, změny měřítka a posunu mezi digitálními obrazy. Fázová korelace je založena na Fourierově transformaci, proto je popsána Fourierova transformace funkcí definovaných na R^2 i diskrétní Fourierova transformace funkcí definovaných na konečném počtu bodů {0, 1, ... , N-1}^2, kde N je přirozené číslo. Dále je pozornost věnována modifikacím fázové korelace, díky nimž metoda umožňuje nalezení parametrů podobnostní transformace i mezi obrazy, které mají vysoký dynamický rozsah a slabě patrné struktury, obsahují aditivní nebo impulzní šum a jsou pořízeny pomocí různých snímačů a optických soustav. Obsahem práce jsou i modifikace metody pro snímky sluneční koróny pořízené během úplných zatmění Slunce, což patří mezi nejobtížnější úlohy registrace obrazů.

Voleyball player performance applied to overthrows in match
Zapadlo, Jakub ; Buchtel, Jaroslav (advisor) ; Vorálek, Rostislav (referee)
Name: Voleyball player peďormance applied to overthrows in match Objectives: Men's national team valuation of selected individual skills depending on course in particular matches at European Championship 2005. Methodics: Head basis was watching videos of all men's national team matches in basic pool at European Championship 2005. To determine rate of success we used four-level scale connecting with situation, in which were participated selected specialized players: spikers, blockers and diagonal players, until one team gains a point. For watching we used videos from Men's European Championship 2005. Issues: After valuation we concluded that rate of success in individua! skills is not directly connected with point variation. Key words: voleyball, serve, offensive stroke, block, spiker, blocker, diagonal player, peďormance, player, team, rate of success
