Stanovení únavové životnosti při působení hlavních napětí
Balda, Miroslav ; Svoboda, Jaroslav ; Fröhlich, Vladislav
Structures, in general, are exposed to random excitations, which generate normal and torsional stresses. While an estimation of fatigue life is rather well known for uniaxial stress, quite different situation holds for combined random stress. A new approach to the title problem is described lower. It is based on cumulation of stress energy density in peaks of a complex damaging stress.

Berka, Kryštof ; Procházka, Pavel (advisor) ; Dyba, Karel (referee)
The aim of the bachelor's thesis is economic development assessment among and within BRICs countries in the context of developed world during 2007-2015. Based on yearly panel data, an analysis for following macroeconomic indicators was carried out: gross domestic product, inflation rate, unemployment rate, current account on the balance of payments, exchange rate. The profound analysis of selected indicators is instrumental in the comparison of member states and is supplemented by the comparison of BRICs and G6. Based on its evidence, I come to a conclusion that the BRICs as a whole succeeded in establishing as a strong global actor. That has been achieved with the help of global financial crisis, but also with regard to the economic policy implemented in 2007-2015. As a result, GDP of BRICs in terms of GDP of G6 achieved stable growth rate leading to its increase by 52 %. Besides providing main findings, outcomes of this thesis enable to identify main weaknesses and strengths of BRICs economies affecting the prospects for continuance of stable economic growth.

Effect of high temperatures and different water regimes on selected winter wheat varieties above-ground biomass production
Hlaváčová, M. ; Klem, Karel ; Hlavinka, Petr ; Trnka, Miroslav
The aim of this study was to assess the effect of high temperatures and soil water scarcity during anthesis on the above-ground biomass allocation of the two winter wheat varieties (Bohemia and Pannonia). The six growth chambers were used to simulate heat stress conditions within following gradient of temperature maxima: 26°C (control chamber), 29, 32, 35, 38 and 41°C. The relative humidity (RH) course and photosynthetically active radiation (PAR) intensity were controlled via protocols. Additionally, drought stressed (Dry) and well-watered (Wet) treatments were established within each growth chamber. The plants were removed from the growth chambers after 14 days and they were left until a full maturity, exposed to ambient weather conditions. The spike productivities of the main spikes and harvest indices (HI) of the main spikes were evaluated for particular treatments within both winter wheat varieties after harvest.

Účinky xenobiotik na oxidační stres, metabolizmus lipidů, integritu DNA a životaschopnost lidských buněk a rybích spermií in vitro
LINHARTOVÁ, Pavla
Pollution of the aquatic environment by inorganic and organic chemicals is a major factor posing a serious threat to the survival of aquatic organisms including fish. In addition balancing risks and benefits of fish consumption is nowadays an intensively discussed public health topic. Spermatozoa of almost all fish species are released into water environment where they can be directly exposed to various compounds, such as xenobiotics including toxic metals, prior to fertilization. In addition, exposure of parental adults to various xenobiotics may affect gamete quality, which may subsequently reduce fertilization success. On the other hand the advantages of eating fish are well-known, not only in the point that fish is a healthy source of protein and other nutrients, but eating contaminated fish may also confer various health benefits. Research over the past few decades has shown that the nutrients and particularly the n-3 fatty acids (FA) found in fish and seafood, are for examples protective against cardiac diseases and have a positive impact on brain development. The thesis provides a focus on two different cell model types. Firstly, human hepatocellular cells (Hep G2, ATCC) were used as in vitro tool for studying the effect of the intake of cadmium (Cd2+) contaminated fish on cytotoxicity, oxidative stress and fatty acid and phospholipid class compositions. Secondly, spermatozoa of one threatened species of fish, sterlet (Acipenser ruthenus) were used as in vitro model for studying effect of potentially hazardous xenobiotic compounds' occurring in open waters. Sperm from sterlet were exposed for 2h to environmentally relevant concentrations of DQ (0-150

Summary of foreign knowledge about the origin and development of EDZ in crystalline rocks - research
Vavro, Martin ; Souček, Kamil ; Staš, Lubomír ; Vavro, Leona
Presented search summarizes findings of foreign research oriented on the origin and evolution of the excavation damaged zone in crystalline rocks with a particular focus on the essential results of experimental projects which were performed in Canada, Sweden, Finland, and Switzerland. The study is divided, excluding the introduction, into seven main chapters of the text, which gradually deal with: (1) definition of key terms, (2) overview of the main underground research laboratories in the world where EDZ assessment was conducted, (3) methods suitable for EDZ description and characterization, (4) main factors influencing the origin of failure around the excavations and time-dependent evolution of EDZ. An overview of important outcomes of EDZ experiments, focusing on the European hard rock laboratories (Stripa, Äspö, Onkalo/Olkiluoto and Grimsel), and their summary are presented in the final two chapters.\nThe review summarizing the published key findings and results of in situ experiments shows, that for rock in lower stress state, i.e. in no spalling environment, the extent and character of rock mass damage is typically dependent on the excavation method. Using mechanical excavation, rock damage zone with thickness less than 3 centimeters can be originated. The microcracks within this zone contribute to the increase of hydraulic conductivity of the rock mass. At some test sites (Äspö, Grimsel), where the tunnel boring machine technology was used, the damage zone was already detected in depth of less than 5 mm.\nOn the contrary, openings excavated by drilling and blasting are characterized by much more extensive damage zones up to several tens of centimeters in width. The damage progressively diminishes with the distance from the opening.

Tool to assess the landscape connectivity in different area units and dispersal distances
Chrumko, Adam ; Šímová, Petra (advisor) ; Krčílková, Šárka (referee)
The purpose of this diploma thesis is to introduce a basic summary of landscape connectivity calculations mainly focusing on the Conefor program and the effect of input parameters on output landscape connectivity indices. One of the main goals is to create an ArcMap Toolbox to simplify the calculation of landscape connectivity indices for many areas of interest. Basic squares that cover the whole Czech Republic were chosen as main areas of interest. These units are used for example for mapping the abundance of flora and fauna. The same indices were calculated for NUTS3 and LAU1 areas in order to compare effect of size of input areas. This thesis provides a simple solution in the form of a Python Toolbox for Esri ArcMap to calculate overall indices of landscape connectivity through a Conefor command line application for a large number of input areas. Forest connectivity for different dispersal distances and input areas of interest was calculated with this Toolbox. As an input vector layer of forests, CORINE land cover data from mapping period 1990, 2000, 2006 and 2012 were used. Input dispersal distances were chosen in the range from 50 to 50.000 meters in order to comprehensively describe their effects on indices. Resultant forest and connectivity changes are represented by cartograms; the effect of input data on output indices is shown in graphs.
