Photocatalytic activity of printed hybrid layers of titanium dioxide
Sýkorová, Kateřina ; Krystyník, Pavel (referee) ; Veselý, Michal (advisor)
The main aim of this thesis was to optimalise composition of the titanium dioxide with a silica binder deposited on a PET foil. Emphasis was put on achieving maximum possible adhesion and hardness of the layer and the effect on photocatalytic activity. For the evaluation of photocatalytic activity comparative experiments with prepared layers were performed. Benzoic acid, dimethyl sulfoxide and azo dye Acid Orange 7 were used as model pollutants. Photocatalytic activity was investigated using UV-VIS spectrophotometry, formal rate constants and degree of conversion were also determined. The study results can be used for removing water pollutants from the water solution.

Anisotropy techniques in study of cytoplasm
Sýkorová, Kateřina ; Obruča, Stanislav (referee) ; Mravec, Filip (advisor)
The main goal of this thesis was to compare experiments using time-resolved anisotropy and steady-state anisotropy for measuring in bacteria strain Cupriavidus necator. Fluorescent probe for anisotropy imaging was chosen BCECF_AM, which is derivate of fluorescein. Using experiment in system glycerol/water with fluorescein, anisotropy has been verified and calculated molecular hydrodynamic volume of a single fluorescein molecule, which approximately corresponded with real value. By using fluorescence imaging anisotropy microscopy, images and values of average anisotropy in cells were taken. Images of living cells (bacteria) of CN H16 and mutant CN PHB-4 showed differences, mainly in the uniformity of the inside environment.

Quantum aspects of particle physics models with extended gauge symmetries
Sýkorová, Kateřina ; Malinský, Michal (advisor)
In this thesis, we study quantum aspects of the minimal renormalizable SO(10) Grand Unified Theory with the scalar sector consisting of 45 ⊕ 126 ⊕ 10C. It is an interesting candidate for a theory describing physics beyond the Standard model which has the potential to allow for proton lifetime prediction with Plank- scale-physics-induced theoretical uncertainties confined within the expected one- order-of-magnitude experimental proton lifetime improvement window. With the complete information about the numerical one-loop scalar mass spec- trum and analytical one-loop beta functions of all the dimensionless scalar cou- plings, we formulate consistency criteria that every viable region of the parameter space must satisfy; namely, we require the existence of a stable Standard-model- like vacuum, unification of gauge couplings and robustness of perturbative calcu- lations. Only narrow parameter space regions around symmetry breaking chains with SU(4)C × SU(2)L × U(1)R or SU(3)c × SU(2)L × SU(2)R × U(1)B−L intermedi- ate stages are demonstrated to be potentially realistic. Detailed analysis of the SO(10) Higgs model with 45⊕126 scalar sector indicates a preference for the for- mer option, mainly due to increased perturbative instability and phenomenologi- cally unsuitable values of energy scales predicted in the...

Effect of activisation programme on independence of elderly in nursing home
Sýkorová, Kateřina ; Daďová, Klára (advisor) ; Majorová, Simona (referee)
Author: Kateřina Sýkorová Title: The effect of an activation program on the self-sufficiency of seniors in a nursing home Objectives: The main objective of the work was to find out whether, after the program, there will be an improvement in self-sufficiency in a group of probands from a nursing home. Methods: The study involved a group of 5 participants from a senior care home, ranging in age from 70 to 90. The group consisted of one male and four female participants. Each participant was engaged in individual exercise lessons focused on the development of fine motor skills, dexterity, and development of sensorimotor functions for 8 weeks (1 lesson per week). The Moberg Pick-Up Test was used to assess the functions mentioned above before and after the intervention. The test was carried out four times with each participant; twice on both the dominant and non-dominant hand, once with visual control and the second time without visual control. Furthermore, after the intervention the participants subjectively evaluated the change in their self-sufficiency using a questionnaire. Results: From the results of the Moberg-Pick Up Test suggest that there was an improvement in 8 out of 16 measurements of fine motor skills. Two participants showed improvement in speed by more than 10 % multiple times....

Use of geochemical archives for the investigation of historical Hg deposition
Sýkorová, Kateřina ; Ettler, Vojtěch (advisor) ; Zuna, Milan (referee)
Human activities affect fluxes of mercury into the atmosphere and modify its biogeochemical cycle. Current emissions, concentrations and deposition rates of mercury are measured by a series of monitoring networks. For the estimation of historical deposition rates of mercury, we use numerous geochemical archives, which represent long-term records of atmospheric pollutants Trends in concentrations and accumulation of mercury well correspond to trends in burning of fossil fuels, industrialization and use of mercury during the 19th and 20th century. Peat bogs as geochemical archives are suitable for studying these trends. Further research will be devoted to deciphering the processes of sequestration and cycling of mercury in peatlands, especially the role of vegetation in these systems.

Issue of using ICT in the work of pedagogical staff in kindergartens
Sýkorová, Kateřina ; Svoboda, Petr (advisor) ; Trojan, Václav (referee)
The bachelor thesis strives to describe the current tendencies in the relation between using ICT in the work of pedagogical staff and the computer literacy of pedagogical staff in kindergartens. The aim of the thesis is to find the relations between the current cognition of the present values of education in ICT, modern managerial terms, including situation and tendencies in pre-school education and the real state of computer literacy of pedagogical staff in kindergartens itself, which is a prerequisite for using ICT in the work of pedagogical staff in kindergartens. The first part defines intentions in strategic documents which are topical in this environment, namely the Main educational policy strategy, information society, learning organization, human resources, including delegation. In the second half it deals with implementation of information technologies into schools, curricular reform, data in strategic documents, information technologies in kindergartens and ICT for educational organization and requirements of the modern age. The research part deals with the current state of computer education and delegation of certain activities using information technologies depending on refutation or confirmation of hypotheses. Based on the study of expert literature, my own practical experience as a...

Sýkorová, Kateřina ; Pařízek, Jiří (advisor) ; Navrátil, Pavel (referee) ; Langrová, Eva (referee)
Bachelor's thesis presented here determines nursing staff knowledge in issues of organ transplantation. The focus of this thesis is a quantitative survey made among nursing staff on the issues of organ transplantation legislation in Czech Republic. The thesis contains information from Transplantation state law, information about the National Registry of persons who disagree with post-mortal use of their organs and tissues and information about the Coordination Centre of organ transplantations. It also considers the determination of death act. The examined sample of population is formed by staff nurses from "Pardubická krajská nemocnice, a.s. "
