Analýza stavu ekologického zemědělství a bioprodukce ve vybraném regionu Zlínského kraje - okres KROMĚŘÍŽ
Ševčík, Jan
The diploma thesis „Analysis of the conditions of the ecological agriculture and bioproduction in the selected region Zlín, Kroměříž district deals with the contemporary conditions of the ecological agriculture and bioproduction in the Kroměříž district and with the availability of a range of goods for consumers. Principals and goals of the ecological agriculture, legislation, control mechanisms and production of the organic food are described in the literature review. History and development of the eco-agriculture in both the Czech Republic and the world are also described here. Next section focuses on the description of the Kroměříž district and its environmental conditions for agriculture as well as of the contemporary conditions of the eco-agriculture and production of the organic food. Last part focuses on the analysis of the companies in which the overall benefits for the region is found out through a questionnaire survey. The second questionnaire will be targeting directly on consumers of the organic food. The research findings and subsequent discussion are summarised in the conclusion.
Robotizované dojení a jeho působení na dojnice
Ševčík, Jiří
The objective of the dissertation thesis was to evaluate the effects of two different types of milking systems (CMS - conventional milking system vs. AMS - an automatic milking system) on average daily milk yield, on frequency of attending robots, on pre-milking teat preparation procedures and stimulation and milking time, on the teats traumatization of Holstein cows. The experiments were performed in two locations: Žabčice School Farm of Mendel University in Brno and ZEMAX, a. s. in Šitbořice. Data was collected for a period 1st January 2014 to 15th December 2015. Higher average milk yield per day and lower milk yield per milking on the other hand on the farm with AMS were caused by a higher frequency of milking. Cows on farm with CMS were milked twice a day. On the farm with AMS dairy cows were milked in accordance with their own needs. Milking frequency in the AMS was in 2014 2.47, in 2015 2.88 per day. Heat stress has negative impacts on milk production. Effect of heat stress showed more markedly in 2015, which is probably related to the fact that the value of THI greater than 80 lasted longer. The length of pre-milking teat preparation procedures and stimulation various neighborhoods was found in AMS in 2014 from 0:13 min. to 0:16 min., in 2015 from 0:14 min. to 0:19 min. On farm with CMS time not be registered. The length of milking time with CMS in both years was 5:02 min. In AMS was in 2014 from 3:03 minutes to 3:53 min., in 2015 from 3:05 min. to 4:45 minutes. In process of milking machine teat traumatization were smaller when using AMS.

The Computational part and project includes design of sanitary and stormwater sewer, water supply system, gas installations a their service pipes to current utility lines.
Technologies of reuse of wastewater in place of need
Podhrázský, Martin ; Ševčík, Jan (referee) ; Hlavínek, Petr (advisor)
Final thesis is focusing on possibilities hidden in the potential of wastewaters in sewers. The goal of this thesis is to present technologies and experiences with water reclamation and with heat recovery systems using wastewaters as a source of heat energy. The theoretical part is divided in two main topics. The first topic is focused on bringing important knowledge and experiences with designing and operating decentralized sewer mining systems, which are, due to less favourable environmental conditions, largely applicated and developed in countries such as Australia, California, etc. The second topic is focusing on heat recovery from sewage water and possibilities of heating and cooling buildings. A possibility of using heat energy from sewage for heating and cooling a swimming pool building located in Brno, Czech Republic was assessed in the last part of this thesis. As a source of wastewater was considered a sewer main located near the pool building. Payback periods and economical effectivity of investing into wastewater heat recovery system was compared with centralized heat supply system, which is a very common source of heat energy in Czech Republic.

Clinical classification of sequence variants in non-coding regulatory regions in breast cancer susceptibility genes.
Bubáková, Eliška ; Ševčík, Jan (advisor) ; Vodička, Pavel (referee)
Inactivation of tumor supressor gene BRCA1 causes a life-long risk of breast carcinoma development. Genetic screenings of indicated individuals from high-risk families help to identify large number of sequence variants in known predisposing genes. Majority of discovered variants doesn't have clinical significance yet which causes a big problem for diagnostics. Some of these variants are found within regulatory non-coding regions of gene. A part of the clinical classification of variants is their functional characterization. The goal of this thesis was to create a model system for functional characterization of variants in non-coding regions and to verify its function. Model system was based on targeted gene manipulation by co-transfecting CRISPR-Cas9 construct and donor construct that contained a portion of BRCA1 gene sequence with analyzed modifications, into U2 OS cells. The cells have stably integrated DR-GFP system which allows the activity of homologous recombination (HR) to be determined. Monoallelic modifications were induced into U2 OS cells. These modifications were in a Kozak sequence region of BRCA1 gene. Expression level of BRCA1 mRNA was determined by qRT-PCR, which showed the same levels of mRNA in all cells with analyzed alterations. Next, expression level of BRCA1 protein was...
Nonlinear phenomena in electrokinetic chromatography
Dovhunová, Magda ; Dubský, Pavel (advisor) ; Koval, Dušan (referee) ; Ševčík, Juraj (referee)
Capillary electrophoresis often uses complexing agents since the interaction between the analyte and the complexing agent can result in achieving or improving the separation. Examples of such methods can be electrokinetic chromatography or affinity capillary electrophoresis (ACE). ACE is used to determine the complexing parameters. In case of chiral separation, this issue gets complicated, since the parameters of the two analytes (enantiomers) are not completely independent to one another. Therefore, a procedure has been proposed in this thesis, that should always be used to evaluate the complexing parameters of two enantiomers. Statistical evaluation of these parameters was assessed as well. This work also proposes a method that allows to determine the relative migration order of two enantiomers in two different complexing separation systems. The mathematical description of electrophoresis is based on continuity equations, that are inherently nonlinear. However, these equations can be linearized to obtain an approximate analytical solution. There was recently presented a generalized model, that enables inclusion of complete complexing equilibria in the theoretical description of electromigration. Thus, various phenomena, including nonlinear ones, associated with complexation can be predicted. This...
Energetic use of wastewater sludge and microwave pyrolysis products
Šimek, Radim ; Ševčík, Jan (referee) ; Hlavínek, Petr (advisor)
The diploma thesis is focused on the energy utilization of sewage sludge before and after microwave pyrolysis process. The first part of the thesis deals with sludge management, treatment of sludge and its subsequent use or disposal. In the second part of the thesis prepared and modified samples of sludge from WWTP 1 and WWTP 2 are subjected to microwave pyrolysis process. Subsequently, samples are taken for analyzes to determine the total organic carbon, the specific surface area, the heavy metal content and the calorific values. The resulting data was processed in Microsoft Office Excel and presented at work. At the end of the thesis two case studies are then proposed for a specific design of the conceptual location of microwave pyrolysis for the sludge drying process and the drying process of the sewage sludge in the direct combustion boiler room.
