The observed changes in selected climatic characteristics
Chládová, Zuzana
Global climate changes are often connected with increasing amount of greenhouse gasses in the atmosphere. Analyses of 22 temperature and precipitation characteristics from the period 1961-2000 showed, that some climate characteristics of the Czech Republic have been changing (mean diurnal temperature range and the number of days in heat waves have increased, length of frost season has decreased). Some characteristics have remained unchanged (maximum seasonal temperature range, length of wet and dry season). Trends of values in autumn proved to be different from other seasons. Comparison of outputs of regional climate model RegCM3 with data from stations in the Czech Republic showed, that model described temporal changes of characteristics, sufficiently, but the mean model values were lower. The coincidence of RegCM3 precipitation characteristics with real data was worse, than the correspondence of temperature characteristics. The mean values of some precipitation characteristics were very different from real ones and they also didn't describe temporal development of characteristics.

Růžička, Tomáš ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
Object of this master thesis is the static verification and variant desing of roof structure of winter sport stadium in Jihlava city. The ground plan dimensions are 60 x 84 m The current structure is composite of truss main girders with parabolic lower chords, and purlins. Axial distances of main girders are 12m. Concrete columns are a support to main girders. The variant desing of roof uses truss girders and truss purlins. They are supported on existing concrete columns. All load bearing members of existing and new design structure have been evaluated according to actual normative rules. The static assessment of the existing structure is not satisfied from viewpoint of ultimate and serviceability limit states (in some elements). The static assessment of the new structure is satisfied from the viewpoint of both limit states.

The issue of the establishment of sheltered housing in the transformation Home Pístina
KUBEŠOVÁ, Stanislava
Sheltered housing is under the act n. 108/ 2006, about social services, defined as a residential service which is provided to people with reduced self- sufficiency because of disability or chronic illness including mental disability whose situation needs help of another person. Sheltered housing can be in a form of group or individual housing. At the beginning of the theoretical part is briefly described mental illness, its causes and classification. Another part is focused on social service system and specification of sheltered housing. The final part of the theoretical part is devoted to transformation process of social services, its present development, financing, criteria and possible risks. The objective of this bachelor´s thesis was to find out and compare approaches of addressed representatives of chosen municipalities to sheltered housing building within the process of transformation The Home of Pístina. The first sub-objective was to find out what problems can arise while looking for new locations for sheltered housing. The second sub-objective was to find out whether the public is informed enough concerning providing social service and about clients and their integration into society. To determine the set objective was used a qualitative research. Data was obtained by interviewing using a structured interview technique with open questions. Sample consisted of two types of respondents - representatives of communities A,B,C and a worker of South Bohemian Regional Authority. The research showed very different opinions and approaches of representatives in individual communities to sheltered housing building and to its clients as well. In the community A, where municipal authority understood the change of social service system in form which will not separate users of these services from the other inhabitants, all negotations about realization of this change proceeded without problems. Certain worries were mentioned by representatives about free movement of people with mental disability for reason of their abuse and ability to adapt to the new environment. In the community B, the situation was completely different. Municipal authority did not show any interest in building of sheltered housing.The problems arose at the very beginning with purchase of land. There was a lack of awareness about the process of social service transformation and about people who will use this service. Awareness of people about this issue led to worries about unsuitable behaviour of mentally disabled people in public. The research indicates the need to increase awareness of general public about facilities providing social services and about their clients. In case the county does not get this possibility from the community, it should explain the issue to the inhabitants itself in another suitable way and help people with mental disability to integrate in the society of selected location.

Higher education in Austria: the rule of law , case studies and implications for Czech Republic
Kravcivová, Aneta ; Neumann, Pavel (advisor) ; Antal, Jarolím (referee)
In 2015, Wien Wirtschafsuniversität ranked among economic universities regularly disclosed on the Financial Times in position number 42. The University of Economics last three years, around 80th place. Why is this so? In the context of this thesis is to analyze not only the legal prerequisites for successful graduates of the master's program Finance and Accounting, but also deals with the practical use of knowledge on the labor market resp. As well as the current unemployment of graduates in what fields they can work, etc. In this work also deals with the human capital theory, which explores the motives for higher education. They are given different conditions during their studies at WU and Economics, as well as development starting salary after graduation. The last chapter contains examples that would be good to apply in the Czech higher education system. The question remains, why WU placed on better positions than ALL? According to the author's investment in science and research in Austria - currently invest nearly 2% of GDP, as well as 100-year-old development WU, when no interruption to develop economic theory and their application in practice, as well as linking university knowledge with practice.

Potential contrast agents for MRI based on manganese (II) complexes
Drahoš, Bohuslav
The thesis is focused on the synthesis and characterization of novel Mn2+ complexes as alternative to Gd3+ chelates which are wide-spread contrast agents in Magnetic Resonance Imaging (MRI). In the perspective to find suitable chelators of Mn2+ , three groups of pentadentate ligands with different size of macrocylic cavity, different donor atoms and number of pendant arms containing various functional groups have been investigated. Coordination numbers of 6 or 7 were found in the crystal structure of the Mn2+ complexes enabling binding of one or two water molecules in the first coordination sphere. The direct water coordination causes a decrease in the complex stability and thus, the thermodynamic stability of investigated chelates is lower than that of polyaminocarboxylate complexes and their dissociation is very fast in comparison to [Mn(nota)] and [Mn(dota)]2- . The studied Mn2+ complexes do not undergo oxidation in air except for complexes with 12-membered ligands which are oxidized to Mn3+ species. The proton relaxivities of the bishydrated complexes are two times higher than those for monohydrated complexes and are comparable to those of commercial contrast agents based on Gd3+ complexes. Variable-temperature 17 O NMR data revealed that the water exchange varies from slow to intermediate or...

Monitoring of water use, druought and yield impacts of winter wheat using imaginery from satellites
Jurečka, František ; Anderson, M. ; Hlavinka, Petr ; Semerádová, Daniela ; Trnka, Miroslav ; Hain, C. ; Gao, F. ; Yang, Y. ; Žalud, Zdeněk
Remote sensing can be very useful tool for drought monitoring, providing valuable information about yield-limiting moisture conditions and crop response under current climate conditions. In this study the Atmosphere-land Exchange Inverse (ALEXI) model was used. The ALEXI model uses the morning surface temperature (LST) rise and provides information on the surface moisture status. In this paper correlations between yields and satellite indicators of crop water use or evapotranspiration (ET) were studied for the period 2002-2014. Correlations were studied for winter wheat at district scale in Vysocina, Jihomoravsky and Olomoucky regions since winter wheat is one of the traditional and most important crops grown in these regions. The Evaporative Stress Index (ESI) was used for these correlations as an ET-based index. Time series of Pearson correlation coefficient (r) computed between ESI and winter wheat yields at district scale were analysed. Strongest correlations are associated with districts within the Southern Moravian lowlands in Jihomoravsky and Olomoucky region, where frequency of occurrence of severe drought was highest over the period of record. Severe drought resulted in significant yield impacts, particularly in years 2003 and 2012. Correlations tend to be lower over the highlands districts of Vysocina and surroundings. In these districts, yields are more temperature than moisture limited and were more stable over the period of record.

Microstructure and Properties of Spark Plasma Sintered Al-Zn-Mg-Cu Alloy.
Zyka, J. ; Málek, J. ; Pala, Zdeněk ; Andršová, I. ; Veselý, J.
High entropy alloys are a new material class with promising structural and mechanical properties in wide range of applications. In principle they consist of five or more elements in equimolar concentrations resulting basically in single phase microstructure. TaNbHfZrTi alloy was developed by Senkov for high temperature applications.\nSince all of these elements are biocompatible the TaNbHfZrTi alloy can be investigated as a prospective bio implant material. The alloy was prepared by vacuum arc melting, no annealing treatment was applied. Tensile test and hardness test at room temperature were performed with very good results: yield strength 1155 MPa, rupture strength 1212 MPa, Vickers hardness 359 HV30. Microstructure and fracture morphology was also investigated.

Temperature and pressure correlation for volume of gas hydrates with crystal structures sI and sII.
Vinš, Václav ; Jäger, A. ; Hielscher, S. ; Span, R. ; Hrubý, Jan ; Breitkopf, C.
The temperature and pressure correlations for the volume of gas hydrates forming crystal structures sI and sII developed in previous study [Fluid Phase Equilib. 427 (2016) 268], focused on the modeling of pure gas hydrates relevant in CCS, were revised and modified for the modeling of mixed hydrates in this study. A universal reference state at temperature of 273.15 K and pressure of 1 Pa is used in the new correlation. Coefficients for the thermal expansion together with the reference lattice parameter were simultaneously correlated to both the temperature data and the pressure data for the lattice parameter. The new correlation is in good agreement with the experimental data over wide temperature and pressure ranges from 0 K to 293 K and from 0 to 2000 MPa, respectively. The new correlation provides significantly better agreement with the experimental data for sI hydrates compared to the original correlation. The results of both correlations are comparable in case of sII hydrates.
