Uptake and Distribution of Chlorphenols in Barley
Jíšová, Tereza ; Forczek, Sándor ; Tesařová, E.
Chlorinated phenols represent one of the most common groups of toxic industrial compounds.\nThey are resistant to biodegradation in the environment and persist for a long time. Food crops\nsuch as spring barley, are susceptible to contamination by various pesticides and organic waste,\nand these substances can then get into the plants. Uptake and distribution of 2-chlorophenol were\ninvestigated in axenic spring barley. After absorption of 14C-labelled 2-chlorophenol, the plants\nwere harvested and extracts were analyzed for 2-CP derived radioactivity. The uptake of 2-CP to\nroots and transport to leaves were confirmed. Radioactive balance was calculated for individual\nplants.

Distance Protection for Parallel and Double-Circuit HV Lines
Muhayimana, Obed ; Wannous, Kinan Hasan Wafaa (referee) ; Orságová, Jaroslava (advisor)
Chránění paralelních a souběžných vedení je skutečně problematické z důvodů účinku vzájemné indukčnosti vedení v souběhu, odporu poruchy nebo rozložení zpětného proudu poruchy, které zkreslují impedanci jednofázové poruchy „viděné“ distanční ochranou. Proto současné numerické distanční ochrany nabízí kompenzační funkce, které je možno použít pro korekci charakteristik a výpočtu vzdálenosti poruchy pomocí lokátorů její charakteristice s dostatečnou odporovou rezervou a možnosti nastavení odpovídajícího režimu vypnutí. Tato práce se zabývá problémy, kterým čelí lokátor distanční ochrany při měření a výpočtu vzdálenosti místa jednofázové poruchy, a také mapuje současný stav řešení těchto problémů. Na základě výpočtu parametrů zadaného vedení bylo provedeno zhodnocení možných chyb při lokalizaci jednofázové poruchy a navrženo nastavení distanční ochrany určené k jeho chránění včetně nastavení parametrů určených pro kompenzaci výše uvedených negativních jevů. Bylo zjištěno, že zemnící lana a transpozice vedení přispívají k přesnosti lokátorů, protože nejmenší chyba byla zjištěna v transponovaném vedení se zemním lanem.

Turn - over positioning table
Mareček, Vojtěch ; Dokoupil, Vladimír (referee) ; Foller, Bronislav (advisor)
This diploma thesis deals with projection and general design of rotary indexing table for dedicated machine tools. The major attention is given to substitution of hydraulic drive table by table driven by servomotor, namely double axis its positions in vertical and horizontal directions. The total configuration of rotary table is solved as a construction kit, user can used any servomotor and additive gearbox. The work is concentrated to the optimization of table construction for this new designed conception. The positioning and fixing of table plate is solved by couple of Hirth couplings with central hydraulic motor. The computational part of work includes calculations of dynamic of rotary motion of the table and hydraulic system. All important screw connection, gear wheels and Hirth couplings were verified by calculations. Also working lifetime of bearings and strength deformation of major constructional sections of rotary table verification were controlled. Inherent part of work is security analysis, economics analysis, patent search and analysis of construction identity. Presented work contains three-dimensional model, drawing documentation of both variants of configurations and production drawing of major section parts of rotary table.

Quantitative Easing and its Impact on Wealth Inequality
Lazar, Stefan-Alexandru ; Taušer, Josef (advisor) ; Čajka, Radek (referee)
The aim of this thesis is to show how the unconventional monetary policy rounds of Quantitative Easing introduced in the United States between 2008 and 2014 have led to an increase in wealth inequality. The need for the thesis arises due to the uncharted nature of QE and because of more and more information is surfacing to light which points to this connection. By analysing the distribution of these funds and adding it to the then base distribution of money supply, this study was able to determine a significant 10 % increase in the Gini Index. Furthermore it highlights how a large portion of wealth was transferred from the middle class over to the top 5 % income households. Starting from a set of assumptions the calculation is performed by extrapolating the data required and by isolating the system from any external variables. The result is a theoretical model meant to describe the mechanism that links Quantitative Easing to wealth inequality. Moreover a detailed comparison is provided with the effect of a conventional monetary policy such as Open-Market Operations. Finally solutions to this issue are being discussed from economical, political and fiscal standpoints.

Load bearing RC structure of the multiple dwelling
Janisch, Filip ; Perla, Jan (referee) ; Šimůnek, Petr (advisor)
The project deals with the lower part of the construction of a residential building. The parking spaces are situated in three underground floors. The five floors occur in the over-ground part of the building. The building is based on the secant walls of Milan around the perimeter. Internal walls and columns are supported with micropiles. In this project are designed base plate, external walls and stairs. Static system and the calculation of the internal forces was carried out in Scia Engineer 2012 Student version.

Centra rekombinace v semiizolačním CdTe
Zázvorka, Jakub ; Franc, Jan (advisor) ; Fiederle, Michael (referee)
Title: Recombination centers in semiinsulating CdTe Author: Jakub Zázvorka Department / Institute: Institute of Physics of Charles University Supervisor of the master thesis: prof. Ing. Jan Franc, DrSc., Institute of Physics of Charles University Abstract: The properties of CdTe for application as a radiation detector are influenced through the presence of deep levels in the bang gap. These energy levels complicate the charge collection and the detector efficiency. Contactless resistivity mapping (COREMA) represents a good option for material characterization without the necessity of metal contacts application. The time-dependent charge measurement was investigated on an adjusted apparatus in FMF Freiburg. Theoretical model of charge transport based on band bending on the sample surface was proposed and a non-exponential behavior was calculated. Using this, the resulted parameter tendencies and their connection with deep level trap or recombination center were explained. A correlation was observed between resistivity, photoconductivity and a near midgap level photoluminescence. Parameter profiles were explained using the theory of Fermi level shift relative to the near midgap level. Three deep levels were observed on samples grown at the Charles University in Prague. Their photoluminescence supports the...
