Analysis of erosion and runoff conditions in the Rozdrojovický stream watershed
Hegenbart, Vlastimil ; Pavlík, František (referee) ; Dumbrovský, Miroslav (advisor)
The subject of this bachelor thesis is to analyse the area with regard to erosion and runoff conditions and the transport of sediments into the Brno dam. The erosion calculation is carried out in two variants when the R-factor is changed. The USLE equations were used for the erosion calculation. The analytical work is carried out in ArcGIS software, where critical profiles with the corresponding collection areas were determined and then erosion and peak flows calculated on them and the erosion shear and basic characteristics of direct runoff were calculated. The DesQ-MaxQ program was used to calculate the flows in each catchment. The result of the work is an analysis of the area in terms of erosive shear to the Brno dam.
Proposal of documentation of the technical solution of the system of soil erosio control and flood protective measures in the cadastral area of Mazorníkovo
Štulajterová, Laura ; Pavlík, František (referee) ; Dumbrovský, Miroslav (advisor)
The aim of the thesis was to evaluate the erosion and runoff conditions in Mazorníkovo and its surroundings, in the cadastral area of Brezno in variants comparing the current state and the prediction of the state in 2050 as a result of climate change. The part of the analysis was also a detailed draft of adaptive protective measures, including the documentation of the technical solution.
Study of the proposal of soil and water conservation measures for the protection of the built-up area of the Mazorníkovo district
Štulajterová, Laura ; Pavlík, František (referee) ; Dumbrovský, Miroslav (advisor)
The purpose of this bachelor’s thesis is to analyze the area of Mazorníkovo and determine the erosion and drainage conditions and then based on the results, design a proposal of erosion and flood control. In the software ArcGis, via the digital model of elevation were critical points, where the accumulated surface runoff enters the urban area, identified. The value of peak discharge for each point was defined by using the software DesQ – MaxQ. To calculate erosion, the universal soil loss equation USLE was used. Once all the information was assessed, the proposals of erosion and flood control erosion and flood protection were made to reduce soil transport into the urban area and protect the lives and properties of the citizens.
Identification of critical points and the evaluation of their contributing areas in the Čižina watershed.
Hanuliak, Radek ; Pavlík, František (referee) ; Dumbrovský, Miroslav (advisor)
The aim of the bachelor thesis was to evaluate the critical profiles in the village of Lichnov near Bruntál. There was perfomed an identification of critical profiles, which are decisive for the flood threats of the built-up area. An analysis of the complex of physical-geographic factors influencing direct drain, soil loss and sediment transport was realised in collection areas. Evaluation was carried out using DMT, with the use of tools of ArcMap and DesQ.
Metabolism of anthelmintics in plants
Pavlík, František ; Szotáková, Barbora (advisor) ; Vokřál, Ivan (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biochemical Sciences Candidate: František Pavlík Supervisor: Prof. Ing. Barbora Szotáková, Ph.D. Consultant: RNDr. Radka Podlipná, Ph.D. Title of diploma thesis: Metabolism of anthelmintics in plants Anthelmintics enter into environment mainly through excretion of treated animals. They may cause a lot of adverse effects in ecosystem as they can affect non- target animals or they can accumulate in plants. Further, after consumption of these plants by livestock on pastures the resistence of helminths can be induced. Therefore, the present study was designed to find out biotransformation of frequently used anthelmintics flubendazole (FLU), albendazole (ABZ), fenbendazole (FBZ), ivermectine (IVM) and monepantel (MOP) by the common meadow plants harebell (Campanula rotundifolia) and plantain (Plantago lanceolata), which may often come into contact with anthelmintics through the excrements of treated animals. As model systems, suspensions of harebell and plantain cells and in vitro regenerants of plantain were used. There was no toxic effect of anthelmintics for these plants; they were able to metabolize anthelmintics into a wide scale of various compounds. These metabolites were identified by ultrahigh-performance liquid...

Identification and stabilization of concentrated runoff waterways in the watershed of Prusanka and Mutěnický creek
Horký, Štěpán ; Pavlík, František (referee) ; Dumbrovský, Miroslav (advisor)
The subject matter of the thesis is the identification of concentrated runoff waterways in the landscape and their consequent stabilization. The municipalities of Čejkovice and Mutěnice in the South Moravian region were analysed in order to reach this purpose. The thesis introduces theoretical bases for the definition of concentrated runoff waterways and their application in the calculation. The area was analysed on the basis of the digital elevation model in ArcGIS software environment. The CN curves method by means of the hydrological model DesQ – MAX Q was used for the calculation of concentrated runoff waterways.
Quantification of natural water retention capacity in selected watersheds
Pavlík, František ; Švihla,, Vladimír (referee) ; Pavelková,, Renata (referee) ; Dumbrovský, Miroslav (advisor)
The aim of this work is to quantify the natural water retention capacity of the landscape in selected catchments and determine the significance of selected climatic and geographic basin factors on components of retention capacity. 18 rainfall-runoff events were selected in 11 catchments for quantification of the natural water retention capacity of landscape. Land cover, geomorphological, pedological and hydrological conditions were analyzed for this basin using GIS tools. Historical rainfall-runoff events for which were restored historical land cover were also evaluated in this work. Two different methods were used for the quantification of retention capacity, one of them was used in two variants. A rainfall-runoff models and simulated scenarios of land cover (positive and negative) were constructed in two selected catchments in HEC-HMS. The work also use previously performed simulation scenarios of land cover formulated by other authors. Total final set of 33 rainfall-runoff events were subjected to statistical correlation and regression analysis. The goal of these analyses was to determine the significance of individual parameters assessed in relation to the components of natural water retention of catchment.
Study of the effects of ellipticity parameter on lubrication film shape
Pavlík, František ; Dzimko, Marián (referee) ; Křupka, Ivan (advisor)
Diploma thesis deals with elastohydrodynamic lubrication of point contacts, which surfaces are influenced by topography and velocity vector of one rubbing surface is misaligned. Author summarizes knowledge of previously published research articles, which fundamentally enrich current state of knowledge. Diploma thesis contains experimental measurement results of the film thickness and the way of lubrication film formation in elliptical contact for different ellipticity parameters, kinds of rubbing surfaces and angles of the velocity vector. New findings have helped to better understand the behaviour of highly loaded lubricated contacts taking place in machine components and completed the current state of knowledge with results that can be used in next thorough study of this issue.
