Vliv čistírny odpadních vod v obci Luka nad Jihlavou na kvalitu řeky Jihlavy

Hanáček, David January 2019 (has links)
Diploma thesis is focused on the assessment of the impact of sewage treatment plant in the village of Luka nad Jihlavou on the quality of the river Jihlava. Assessment of the influence of the WWTP is based on field monitoring, with sampling of water for subsequent laboratory analysis. The literary research deals with the purification and treatment plants, water legislation, types of water, pollution of surface water, death of fish on accidental water pollution and evaluation of water quality according to ČSN 75 7221 and government Regulation no. 401/2015 Sb. In the literary overview is also given the description of the indicators field monitoring and laboratory determinations. The methodological section describes the principles of individual determination of the field survey and analyses of water samples in the laboratory and characteristics of the sampling sites. Results and discussion chapter based on the graphically processed results to assess the impact of WWTP on water quality in the river Jihlava. From the obtained data it follows, that, despite some exceedances of the limit the boundaries of reading to CSN 75 7221 and government Regulation no. 401/20015, does not significantly affect water quality in the receiving water and not accidental mortalities of the fish community.

Vliv velkého zemědělského podniku na rozvoj venkova

Tomšů, Karolína January 2019 (has links)
The aim of the thesis is to analyze chosen agricultural companies and thein relationship to municipalities in which they agriculturaly work. Demographic study and analysis of the selected farm were used to achieve the aim: a questionnaire focused on supplier-customer relations and an interview on the company's history and relationship to the municipality. At the end of the thesis, it results that influence of agricultural companies on rural development is not generalizable and it can not be seen only by an economic aspect. Emotional bondining to the place of business and the established social definition of rural areas play a role in agricultural companies.

Vliv složení kultivačního média na metabolismus rostlin tabáku / Influence of cultivation medium composition on metabolism of tobacco plants

Minářů, Kateřina January 2010 (has links)
Phosphoenolpyruvate carboxylase (EC 4.1.1.31; PEPC) plays many roles in plants; it connects the metabolism of saccharides and amino acids. PEPC is regulated at many levels including phosphorylation of serine residue near N-terminus. The aim was to found out, if the composition of cultivation medium affects the activity of PEPC and metabolically related enzymes such as NADP-malic enzyme (EC 1.1.1.40), pyruvate, phosphate dikinase (EC 2.7.9.1; PPDK) and enzymes participating in nitrogen assimilation, thus nitrate reductase (EC 1.7.1.1; NR), glutamine synthetase (EC 6.3.1.2; GS), glutamate synthase (EC 1.4.1.14; GOGAT), NAD-glutamate dehydrogenase (1.4.1.2; NAD-GDH) and NADP-glutamate dehydrogenase (1.4.1.4; NADP-GDH). Tobacco plants (Nicotiana tabacum L., cv. Petit Havana SR1) were grown in vitro in Murashige-Skoog agar. The effect of the presence of 2% succrose, reduced content of nitrogen compounds or phosphate and limited supply of CO2 was followed. Sucrose added to Murashige-Skoog medium caused the increase of enzyme activity of PEPC, NADP-ME and most of enzymes related to nitrogen uptake and metabolism - NR, GS, GOGAT, NAD-GDH a NADP-GDH. Reduced content of nitrogen compounds and phosphate in cultivation medium decreased activity of all monitored enzymes. Enzyme activities were also affected by the...

Instituce a organizace židovských obcí v Čechách v 17. a 18. století / Jewish Self-Government in Bohemia in 17th and 18th Centuries

Holeček, Kajetán January 2020 (has links)
The presented M.A. thesis pursues Jewish self-government in Bohemian towns and villages during the 17th and 18th centuries. Based on communal statutes of Jewish communities in Chodová Planá, Nové Sedliště, Rožmberk nad Vltavou, Rychnov nad Kněžnou and Tachov the study describes constitution of local self-government and agenda of communal officials. Even though the sources originate from communities scattered throughout Bohemia, we can find plenty of shared topics contained in the statutes. Thanks to this parallelism the study can outline common features of the Jewish self-government, of relation between Jewish communities and manorial lords and of everyday life in this communities.

Vyhodnocení účinnosti čistírny odpadních vod v Lipníku nad Bečvou

Masařová, Markéta January 2017 (has links)
The thesis "Evaluation of the effectiveness of the wastewater treatment plant in Lipník nad Bečvou" compares the effectiveness of wastewater treatment before and after the plant reconstruction. This work is comprised of the theoretical and practical part. The theoretical part applies overview of the water law legislation, sewerage, types of wastewater and concrete methods of wastewater treatment. The practical part is focused on wastewater treatment in the city. Included is the transport of wastewater, description of treatment technology before and after plant reconstruction. Follows the graphical results of wastewater treatment plant load, analytic wastewater checks and effectiveness of the WTP (Wastewater Treatment Plant) in years 2005 and 2015. The results show that the original wastewater treatment technology was, according to compliance with the emission standards, insufficient. For this reason, complete WTP reconstruction followed. From the current WTP results, it is evident that the hydraulic load is at 50 % average, but it is overloaded with the substance. Despite this fact, WTP maintains its high effectiveness in pollution elimination. The levels of pollution on the WTP output do not exceed the values of the emission standards and limits.

Obnova lesa na kalamitních holinách VLS, s.p., divize Lipník nad Bečvou, LS Hlubočky

Provazníková, Pavla January 2017 (has links)
The aim of the dissertation was to analyze the state of cultures in bare areas incurred by the withering away of spruce growth. The dissertation was undertaken on the properties of VLS ČR, s. p., in the economic forest unit of Hlubočky and Bores. The monitoring took place in 18 research areas which were afforested between the years 2007-2015, where 9 areas were afforested with Norway spruce and 9 with European beech. The height of the over ground part and the thickness of the root crown were measured and the presence of damage caused by wild game was evaluated. The monitoring for the purpose of establishing the state of the young spruce and beech growth took place in 10-15 year old growth areas where the trees per hectare, damage by wild game and the percentage of defoliation were evaluated. The third aim of this work was the framework evaluation of the afforestation costs and the care of the cultures according to data from forest management accounting. The monitoring of research areas afforested between the years 2007-2015 found that beech plants were more damaged by browsing than spruce plants. The monitoring of young spruce and beech growth established more damage of the young spruce plants by deer barking and browsing rather than the young beech plants, which are healthier. It was further discovered that the beech growth from natural renewal, which are thicker, are less damaged by wild animals. The evaluation of data from the forest management accounting established that the costs for one renewed hectare on average amount to CZK 64,000, the treatment of one hectare against forest weeds on average cost CZK 9,700 and the protection of one hectare against wild game expends on average CZK 3,470.

Biomass estimation of European beech stands

Veselský, Marek January 2017 (has links)
Forest ecosystems plays an important role in the global carbon cycle of carbon sinks of terrestrial ecosystem. Carbon sequestered or stored in forest trees is mostly referred to as the biomass of tree, site or forest. This diploma thesis deals with biomass estimation of European beech stands at the Holíkov (the Drahanská vrchovina Highlands) and Štítná nad Vláří (the Bílé Karpaty Mts.) study sites in the Czech Republic. Study was conducted in the period of 2010 to 2015. 65 allometric equations were tested for the purpose of determining the most suitable candidate for the estimation of aboveground and belowground biomass of stands and of all the major tree compartments. It is obvious from the results that the allometric equations performed very differently from each other. It was also found, based on the obtained results, that the most suitable allometric equations for the study sites are by Vejpustková et al. 2013 and Wutzler et al. 2008.
