Charakteristika a srovnání přístupu francouzské a české generace Y k pracovnímu uplatnění.
Tesařová, Eva
The diploma thesis deals with the generation Y and its approach to employment. The theoretical part is devoted to generational theories and characteristics of existing generations and detailed focus on generation Y. Practical part focus on surveys realized on the topic generation Y in the labour market. There is also own survey in the practical part. The goal of the survey is the comparison of generation Y in Czech Republic and French and its approach to labour market. Based on the results of the researches, proposals are recommended for employers to introduce new instruments for adaptation generation Y in the workplace. Consequently there is assessment of costs for these proposals.

Koval, Dušan ; Jelínek, Ivan (advisor) ; Feltl, Ladislav (referee) ; Tesařová, Eva (referee) ; Stránský, Zdeněk (referee)
CoNcLUstoNs This work demonstrates that capillary electrophoresis is a suitable method for analysis and physico-chemical characterization of biomolecules. lt was exemplified by px" determination of a series of nove| phosphinic pseudopeptides and by separation oÍ stereoisomers of the phosphinic pseudopeptides and serine' A self-consistent procedure for pK" determination by CZE was carried out' ln particular' various background electro|ýes Were tested in the acidic region at pH < 2. A set of background eIectro|ýes Was eVa|uated for reIiab|e determination of eIectrophoretic mobiIities in the 1.S - 12pH interval. The temperature of the solution inside the separation capillary was measured by a simplified approach, thus enabling precise determination of the electrophoretic mobilities' Additionally, a throughput of the CZE method for the pK" determination was substantially improved, while high separation efficiency and precision of the electrophoretic mobilities was retained. The method benefits from adjustable velocity of e|ectroosmotic flow, achieved by modiÍication of the capi||ary inner surface, and efficient determination of electroosmotic mobility. Further, a study was performed which exp|ored the validity of onsager mode| for theoÍetica| description of concentration dependence of the e|ectÍophoretic...

Bioremediation of persistent aromatic pollutants
Stella, Tatiana ; Cajthaml, Tomáš (advisor) ; Mihaljevič, Martin (referee) ; Tesařová, Eva (referee)
The remediation of persistent chlorinated aromatic compounds has become a priority of great relevance due to the teratogenic, carcinogenic and endocrine-disrupting properties of these xenobiotics. The use of biological methodologies for the clean-up of contaminated sites, collectively referred to as "bioremediation", has been gaining an increasing interest in recent years because it represents an effective, cost-competitive and environmentally friendly alternative to the physico-chemical and thermal treatments. In this respect, "white rot" fungi, an ecological subgroup of filamentous fungi, display features that make them excellent candidates to design an effective remediation technology ("mycoremediation"). In spite of this, fungi have not been widely exploited for their metabolic capabilities and the mechanism by which they are able to degrade the aforementioned pollutants has not been fully elucidated yet. Within this frame, the present Ph.D thesis was aimed at: i) assessing the efficiency of different mycoremediation strategies for the clean-up of a polychlorinated biphenyl (PCBs)-contaminated soil; ii) understanding the fungal degradation pathways of polychlorinated biphenyls and their major metabolites, namely chlorobenzoic acids (CBAs) and hydroxylated polychlorinated biphenyls (OH-PCBs). i)...

Optimization of separation and quantification of prospective products of big bang
Smitka, Jaroslav ; Tesařová, Eva (advisor) ; Kalíková, Květa (referee)
The thesis is a contribution to research aimed at modeling the conditions of the Big Bang and monitoring possible reaction products. As the starting compounds were selected 2- amino-1-butanol, 3-methoxy-1-propanol, 2-methyl-1-butanol, formamide, some of which were subsequently bombarded by PALS at J. Heyrovsky Institute of Physics, Academy of Sciences. Gas chromatography hyphenated with mass spectrometry and liquid chromatography with UV detection were used for analysis. In GC-MS, calibration of 3- methoxy-1-propanol and 2-methyl-1-butanol was carried out and LOD and LOQ were calculated. Comparison of 3-methoxy-1-propanol and bombarded 3-methoxy-1-propanol did not show the emergence of new products since 3-methoxy-1-propanol was in excess. The found compounds can be more likely identified as impurities present in a solvent or in the individual standards. The optimized HPLC system has managed to separate the three standards. Formamide, which is unsuitable for analysis by gas chromatography, due to its high polarity, however, eluted in all tested systems with system peak (the dead time marker). Nevertheless, the bombarded sample was analyzed for comparison with the original standard. Comparison, however, showed no reaction products in the bombarded sample. Key words: big bang laser sparks formamide...

Activity of hydrolytic enzymes in process of prodution of biogas
Kolouchová, Kristýna ; Tesařová, Eva (advisor) ; Kopečný, Jan (referee)
In this work, the activities of hydrolytic enzymes, functioning in the hydrolytic stage of the production of biogas, have been determined. The activities of -amylase, -xylanase, and -glucosidase have been measured in five samples collected from the following steps of biogas production:. cow dung from the adjacent cowshed, cow manure from the homogenization tank for dosing biogas plant, digester sludge from the outside biogas fermenter, degister sludge from the inside biogas fermenter, and sludge of digestate from digestate tank. Samples for measurement of enzyme activities were provided by agricultural biogas station AGRI FAIR in Deštná, which uses for biogas production cow manure and corn silage The activities of hydrolytic enzymes in the production of biogas are crucial, because degradability of feed material is the limiting factor. Activity of a amylase had highest value in cow dung and cow manure due to food containing high levels of starch. In subsequent phases falls evenly. In the indoor digester and digestate is already depleted substrate and the activity is at zero level. Its activity is almost three times higher than - glycosidase in cow dung and cow manure, but in the last three stages of -glycosidase activity exceeds amylase and its value is nearly stable. -xylanase has...
