The goal of this graduation thesis was to find out the influence of milking by automatic milking system (AMS) to the physiological needs of dairy cows within 30 minutes after milking. Ethological study covered the needs for feed intake, water intake and need for lying down. In the next part were obtained data on performance of dairy cows and time data of milking (Preparation time for milking, milking time, and time in the milking box). For determination of an impact of various technologies on dairy cows, the results were compared with the data obtained on the farm with conventional milking technology (auto-tandem parlor). The need of feed intake in 30 minutes after milking was found in the barn with AMS at 75.51 % of dairy cows, in the barn containing auto-tandem parlor it was 84.37 % of dairy cows. Highest rate of silage intake after milking had dairy cows milked by conventional way. The need of water intake was found out in the barn with AMS at 41.79 % of dairy cows and in the barn containing auto-tandem parlor it was 33.45 % of dairy cows. Higher rate of water after milking had dairy cows on the farm using the milking robot. In terms of the needs of feed intake and water within 30 minutes after milking were found in both compared technology almost identical values, 28.23 % on the farm with AMS and 27.27 % on the farm with auto-tandem parlor. From this common intake was observed earlier water intake of animals on both farms of more than 80% percent. The percentage of the cows, which needed to lie down after milking, was found in both technologies very low. On the farm with AMS it was 3.7 % and on the farm with auto-tandem parlor 5.8 %. On the farm, where AMS is used, we could evaluate the physiological needs within 30 minutes after milking in the various parts of a day. The need to feed intake was the highest between 6pm and 12 am) and the lowest in the morning. The need of water intake after milking was highest in the morning between 6am and 12 pm and the lowest between midnight 12am and 6 am. The need of lie down after milking was highest between midnight and 6am and the lowest between noon and 6 pm. Milk yield per milking was 12.89 kg on the farm with AMS and 13.35 kg on the farm with auto-tandem parlor. The average daily milk yield was on the farm with AMS 36.47 kg and 26.7 kg on the farm with auto-tandem parlor. Lower milk yield per milking and higher average milk yield per day on the other hand on the farm with AMS is caused by a higher frequency of milking, among other factors. Preparation time for milking was 2:24 min with AMS and 2:02 with conventional type of milking. The time itself was detected in both methods over 5 minutes. With conventional type of milking the times were longer by almost 30 s (5:41min). The time in milking box was 7:07 min in the technology AMS and 8:16 min in the conventional system of milking. Frequency of using of milking robot during the day reached the lowest rate between 4 pm and 6 pm and between 4 am and 8 am. The increase in the number of milking after 6 pm relates with silage intake at this time. During comparison of analyzed technologies was found insignificant difference in the physiological needs within 30 minutes after milking. For verification of these conclusions it is important to increase amount of farms with conventional milking system.

This thesis deals with issues of upbringing children by their grandparents. It focuses on the fact, how the grandparents handle the upbringining of underage children. The theoretical part is divided into six main chapters. This part includes topics such as family, upbringing and the issue of foster care. The practical part deals with the research itself, as the main research method was chosen to interview and documents analysis. The interview was made with ten grandparents, who have underage child in their custody. The interview was focused on the financial security of families, cooperation with school, the possible educational problems of children at school or at home. Finally, there was made the evaluation based on available data.

The work deals with optimizing the operation of spark ignition internal combustion engine on fuel E85. The theoretical part is devoted to the issue of biofuels in terms of production, distribution and use in internal combustion engines. The experimental part is devoted to the design and verification of the additional control unit (ADU) which solves the optimisation of operation unmodified engine on E85. The first part of the experiment is dedicated to the design and construction of ADU with aim to faultless operation of the engine on E85. The second part of the experiment was devoted to optimisation of engine operation in terms of fuel consumption using dynamic changes of the injectors opening time. Part of the experiments was an evaluation of emissions production and impact on the performance parameters of the engine. The final part of the experiment evaluates the achieved results at the various settings strategy of ADU and compares them with results during engine operation on prescribed fuel N95. By the dynamic change of the injector opening time were reached decrease in fuel consumption by about 5%, reduction in CO production by around 70%, approximately fourfold increase in the production of NOx emissions and about 50% decrease in production of particulate matters.

This diploma thesis deals with saving drinking water supplied in the operation panel house type T06B . Saving solutions drinking water is proposed the use of gray waste water where their collection and subsequent purification will lead to further use. Treated gray wastewater is subsequently used primarily to flush fixtures. For different height levels of the type of building are designed with individual technological units . The proposal includes an assessment of saving drinking water , determination of operating costs and expenses for the purchase of technological equipment .

This thesis deals with the study of the drinking regime for second primary school students and high school students with a focus on drinking schedule at school. The work is divided into theoretical and practical part. In the introduction to the theoretical part there has been characterized the target group. Furthermore, there's given the importance of water for the human body, water balance, principles of drinking regime and specific recommendations for the target group. Furthermore, there's been made a recherche out of several different sources regarding particular nonalcoholic drinks. In the conclusion, the attention is paid to the risks that may be occured due to improper intake of liquids and also to providing the drinking regime in school. The practical part of the thesis describes the research which was done among students and teachers. The way to data collection were questionnaires. Particular results are presented and discussed in the conclusion of the thesis. The results of the survey determine that, although some awareness of the monitored group of students is apparent, keeping the drinking regime principles is unsatisfactory. Based on the research and information from available literature, there've been formulated recommendations for teaching practice.
