Risk of stationary sources associated with valuation of environmental damage
Procházková, Michaela ; Popelová, Barbora (referee) ; Adamec, Vladimír (advisor)
The problems with the environmental damage valuation which are caused by the stationary sources belong to the important issues to be solved. Due to the heavy industrial activity in the Czech Republic it is important to pay attention to the possible risks which can emerge from these sources and can impact the environment and the health condition of people. The thesis deals with the analysis of the present state of this problem. The analysis of the risks which come from the specific situation is made on its basis. The goal of this thesis is to propose the general procedure of the valuation of the incurred damage on the environment and the minimization of the risks.

Phosphorus recovery from liquid digestate
Heger, Jan ; Procházková, Michaela (referee) ; Touš, Michal (advisor)
The focus of this thesis is the posibility of obtaining phosphorus from liquid digestate. The theoretical part of the thesis is focused on summarizing the current situation regarding phosphorus recovery. The research summarizes the essential information about the method of struvite precipitation, by which phoshphorus is obtained in the form of struvite, which can be further used as a fertilizer. Based on the process information, an experimental device was designed to obtain phosphorus in the form of struvite, corresponding to industry standards. It is a cylindrical vessel with a conical bottom, in which the liquid digestate with the chemicals is mixed with a stirrer. The functionality of the device was tested experimentally on the created device. The results of the experiment were analyzed by XPS method, which confirmed the formation of struvite. For future operation, modifications of the device and pre-treatment of the liquid digestate were proposed, which could improve the whole process and its results.

Proposal to Improve the Incentive System and Rewarding of Employees in the Selected Company
Procházková, Michaela ; Sadílková, Hana (referee) ; Konečný, Štěpán (advisor)
This Bachelor´s thesis occupies with the proposal of the improvement of the motivation system and the remuneration of the employees in the representative company. In the theoretical part I am concerned with the theory of the motivation, incentive attitudes, stimulations and last but not least the remuneration of the employees. In the practical part thanks to the questionnaire survey I find out the current state of the satisfaction of the local employees with the motivation, reward system and the employee benefits. I propose the potential dealing with the imperfections.

Winery wastewater treatment
Horňák, David ; Procházková, Michaela (referee) ; Touš, Michal (advisor)
Wastewater management is a current topic for wineries, as wastewater treatment accounts for a large part of operating costs. Currently, technologies based on biological processes are mostly used to treat wastewater from wineries. However, these have a number of drawbacks, such as higher investment and operating costs, a large footprint or the requirement for the necessary technical knowledge of the operators. This paper deals with the selection of an economically less demanding technology for the treatment of winery wastewater and the experimental assessment of its efficiency with respect to the removal of chemical oxygen demand (COD). Photo-Fenton oxidation was selected based on a thorough literature search. The Box-Behnken design was used to design of the experiment. Based on the experiment, the optimum operating conditions were found to be temperature 25 °C, pH 3, Fe2+ ion amount 20,2 mg/l, H2O2/Fe2+ ratio 64 and reaction time 3 h. The achievable COD removal efficiency is 11,8 %, which is not consistent with the values reported in the literature. The main reason for the low efficiency could be the insufficient intensity of the UV radiation used. Further research could build on the optimal conditions found and address the shortcomings of this experiment.

Stability evaluation of cosmetic dispersions using centrifugal analyser
Procházková, Michaela ; Krouská, Jitka (referee) ; Pekař, Miloslav (advisor)
This bachelor thesis is focused on the evaluation of stability of cosmetics emulsions prepared from ingredients commonly available in laboratory and compared to the stability of commercially available body lotions. In the theoretical part cosmetics emulsion and methods used to stability measurements were described. Experimental part of this work at first describes the preparation of the emulsions. Furthermore, the stability of prepared emulsion was compared to commercially available ones using the centrifugal analyser LUMiSizer. In conclusion, the test results obtained from analyser LUMiSizer have showed the stability of the commercial emulsions and two prepared samples.

Criteria Influencing Ski Resort Profits
Procházková Uvizlová, Martina ; Urbánek, Zdeněk (referee) ; Klika, Pavel (advisor)
The main goal of my work is to set the criteria which have an influence on the profit of the ski resorts. The topic deals with building valuation, public database and data about air temperature. The part of the thesis is about building valuation of two companies that own chosen ski resorts. The valuation is done by the definite valuation regulation, single objects in the way given by the valuation notice. For main influential criteria was needed to get the information about profit and expense, this information was necessary for assessment of the company profit. From this information we can say that gross profit relies on the rent which both companies have to pay for ski lift and lift area. Assessment of criteria is about the location of the ski resorts. The most important criteria are the accommodation capacity and the weather. The accommodation capacity is going together with attendance. Because of the possibility of sleeping over the visitors of the ski resorts, the weather and the air temperature have an influence on the snow quality and this is going together with the length of the skiing season.

Detached house with beer-shop in Velké Opatovice
Dostál, Jan ; Procházková Uvizlová, Martina (referee) ; Štěpánek, Ladislav (advisor)
This bachelor´s thesis deals with the processing of project documentation for construction of free-storey, semi-basement, detached house with a beer-shop in Velke Opatovice. The building is designed in a slightly sloping terrain. The beer-shop is located on the ground floor and has its own entrance separate from the residential part. The residential part is made of the boiler room and cellars in the basement, garage, bike storage and drying room on the ground floor, a larger residential unit on the second floor and the attic flat on the third floor in the premises of the saddle roof.
