Information System for Help Desk
Havelka, Ondřej ; Merunka, Vojtěch (advisor) ; Josef, Josef (referee)
The goal of this thesis is to design and implement information system for Help Desk purposes. In the first part there are specifications of theoretical bases, standard procedures and contracts concerning Help Desk operation and also summary of advantages and requirements of such system. Second part contains description of parameters and processes using the BORM method. In the practical part is the implementaion of the designed system on the platform Microsoft Sharepoint 2010. The analytical part contains description of requirements to use this platform and description of functions which are used during the implementation. Final part contains description of the implementation itself. It is based on the parametrs and processes designed in the theoretical part and uses the Sharepoint functions described in the analytical part.

The influence of selection of maize hybrid on forage quality
Pařízková, Josefína ; Hakl, Josef (advisor) ; Josef, Josef (referee)
The aim is to assess the impact of choosing hybrid for digestibility of neutral detergent fiber in forage maize in relation to other quality parameters. Recommendations on hybrids based on testing can be economically advantageous for growers. At the beginning of the experiment hypothesis was stated: Selection of maize hybrid for the habitat significantly affects reached digestibility neutral detergent fiber when harvested for silage. Nine different maize hybrids in triplicate were enrolled in the experiment (Dynamite, NK Octet, Rubben, DKC 3507, 3795 DKC, DKC 4014, Susann, 30,311 LG and LG 32.64) for cultivation on an experimental plot in Prague Uhříněves. The evaluated characteristics were, inter alia, revenue and portion of buds. To evaluate the chemical analysis of samples was collected chop of the whole plant from the middle rows of experimental plots. Following parameters were evaluated: content of crude protein, content of neutral detergent fiber, content of digestible neutral detergent fiber, digestible organic matter, starch and solids content. Among the hybrids significant differences were observed in parameters: revenue, portion of buds, protein content, content of neutral detergent, content of digestible neutral detergent fiber, digestible organic matter and starch content. Statistically insignificant difference between hybrids was at the percentage of the dry matter. Selecting the appropriate corn hybrid is therefore one of the most important measures for cultivation. The correct choice is key to improving the quality of forage for optimal production of livestock. Corn is one of the pillars of production of meat and milk. When choosing a suitable hybrid corn, it is necessary to take into account many factors. Each hybrid has certain characteristics and these must be respected, but also used for benefit. Not only to the price of seeds, but also the potential yield and utilization of nutrients is of great importance for the economy of the production.

Effect of long term fertilization on behalf fraction of nitrogenous substances in fodder alfalfa
Matunová, Jana ; Hakl, Josef (advisor) ; Josef, Josef (referee)
The representation fraction of crude protein in forage legumes significantly influences nitrogen utilization by ruminants. Similar researches were not previously realized. The aim of this thesis is valorizing of long-term fertilization on vegetation structure and representation fraction of crude protein in forage alfalfa. Experimental measurements were carried out at the Research Institute of Crop Production in Prague, Ruzyne. The crop of alfalfa was in the context of long-term fertilization experiment established in the spring of 2013. An attempt with a sown variety Moravia is arranged in the scheme of split-plot. Samples were taken only from the first cut in 2015, each of one line of 50 cm in every block. In the experiment are evaluated four contrasting versions of fertilization (unfertilized control crop, growth fertilized by organic, by mineral and by combination both types of fertilizers). Each variant was repeated for three times. This thesis showed that long-term fertilization influences the parameters of the structure stands of alfalfa. We observed a greater proportion of L/m2 in fertilized variants, an also these stems were higher. Additionally, we observed higher profits, which were in correlation with the sinking share of representation leaves in the growth. Analysis showed that the behalf of nitrogenous substances and individual crude protein fractions is not constant, but is changeable during different variants of fertilization. Unfertilized crop contained on the average 221 g/kg dry matter of nitrogenous substances. The highest protein coken were at crops fertilized organically, 248 g/kg. In the control variant was detected on the average of 328 g/kg of fraction A. This fraction was most abundantly represented in growths with mineral fertilizers, 418 g/kg. On the contrary variant fertilized by combination had the lowest contents of fraction A, 307 g/kg. The highest concentration of B1 was found in mineral fertilized crops, 75 g/kg. For nitrogenous fraction B2 was detected the
highest concentration in crop fertilized by combination of mineral and organic fertilizers, 531 g/kg. For nitrogenous fraction B3 was found the highest concentrations in mineral-fertilized growths (NPK). This value is 24 g/kg. By nitrogenous fraction C was found highest concentration in control growth and crop fertilized with mineral, 80 g/kg. On the contrary, in crops fertilized organically was measured lowest value, 67 g/kg. We can conclude from the results, that the best profile fraction of crude protein has variant fertilized with a combined manner.

Comparison of water bugs fauna in the landscape affected by mining in year 2016
Bubeníková, Jitka ; Vrabec, Vladimír (advisor) ; Josef, Josef (referee)
The thesis compares the composition of water bugs fauna in the foreland of Bílina surface mine and the reclaimed area of its waste heaps. The first part provides information about surface coal mining, its impact on the environment and the methods of treatment of thus disturbed land through reclamation and succession. Fauna of water bugs (Heteroptera) is characterized, with focus on water bugs from Nepomorpha and Gerromorpha infraorders.
During 2016, water bugs were collected by a sieve in 15 locations of the reclaimed area of Radovesice waste dump and Pokrok waste dump, and in 16 locations of Bílina foreground. Bugs were killed by 75% alcohol on the site and in dry condition categorised and classified. A list of found species was prepared for individual tanks. In total, 26 taxa were found (21 of them were classified as species), of which 18 taxa (14 species) in the foreground and 17 taxa (14 species) in the area of the waste heaps. In the richest habitats, an occurrence of 7 species at most was detected. The most frequently represented species was Nepa cinerea which was found in 9 locations.
The main objective of the thesis was to confirm/refute the hypothesis: Due to the good dispersion capability of water bugs, the representation of species in the foreland is the same as the species composition in the tanks that were newly established in the reclaimed area. The species similarity of individual locations was compared with each other by Jaccard's environmental index. Often, the value was 0% and only a small number of pairs of the compared locations reached the value of approximately 50% of the Jaccard's index. The highest value of 71.4% was found during comparison of locations Syčivka-Hetov in the area of Radovesice waste dump. Although the same number (14) of species of water bugs was recorded in the foreground and in the reclaimed area of Bílina surface mine, a significant difference was observed in their species composition. The species similarity of the two designated areas was only 33.3%. Based on the results, the hypothesis was refuted.
