This diploma thesis is a study of the potential of heat transfer enhancement in the process of hydrogenation refining of oil. The simulation of the process and the heat-hydraulic analysis of the heat exchanger network are performed using the software tools. Based on the obtained results and the results of the optimization study, a new heat exchanger is placed in the process and its parameters are subject to further calculations. The aim is to study the possibilities of heat transfer enhancement for the newly used heat exchanger and to discuss aspects connected with the use of selected software.

The task of this master thesis was assessment of the possibility of intensification of biological ponds, which are used for wastewater treatment, and subsequent application of selected systems to the existing wastewater treatment plant in the village Krumsin in the district Prostejov, including economic assessment. In the first part of the master thesis, I worked up the available options for the intensification of biological ponds. In the practical part of the thesis it was prepared a report of the current state of the wastewater treatment plant that serving as a basis for the design of intensification, which is also processed in the practical part. For the proposed variants of intensification was also processed economic assessment.

The thesis presents data from bird monitoring, carried out in agricultural landscape in borderland of Southern Moravia (Czech republic) and Lower Austria (Austria). Relations among habitats and bird species richness and abundance are studied and data from both countries compared.

This diploma thesis is an analysis of the influence of specific socio-political changes to the landscape and agriculture in Czechia. The chosen socio-political changes are the beginning of communist regime in 1948 and the transformation of the whole society after the end of communist regime in 1989. The main idea used in this thesis was the concept of driving forces and the other used concepts were social capital, agricultural diversification and intensification and extensification of the landscape. Detailed presentation of the influence of specific socio- political changes in agriculture and landscape was made by a case study in administrative region Tábor. The used concepts were described In the opening part as well as the main stages of development of agriculture and landscape in Czechia and in the model area. The main method used in the case study were semi-structured interviews with farmers, who were active in agriculture before 1948 and in the time of the research. According to the results of the research the influence of institutional driving forces significantly increased in comparison to the period before 1948. The results also showed to important role of non-productive functions of current agriculture. . Keywords: landscape, agriculture, driving forces, land use, intensification and...

This diploma thesis is focused on the design of technological modifications of the existing industrial unit „waste-to-energy“, used for thermal treatment of process waste gases containing VOC and CO while flue gas is produced. The main objective of the existing unit modification is to improve its operating parameters considering economy, ecology and energy utilization. In the first part, the current industrial plant was presented with all necessary process data. Furthermore, all the key equipment used for the waste gases treatment or for the utilization of waste heat was identified. In the main part of the thesis there are performed modifications of the existing unit including the technology of existing heat exchangers intensification, the design of new and more efficient heat exchangers and finally the catalytic oxidation technology implementation for the decomposition of pollutants contained in the waste gas. The result of the thesis is a technical, economic and ecological comparison of the proposed technological modifications with the existing operation.

Hydrological processes and dynamics in the changing climate and environment: Lessons learned from multiple temporal and spatial scales Ye Su ABSTRACT Climate change, along with the changes in land use and land cover (LULC), is the key factor driving the changes in hydrological processes and dynamics in a basin. This thesis emphasized on understanding the impact of both long-term climate change and abrupt anthropogenic driven agricultural intensification or natural driven insect-induced forest disturbance on hydrological processes and dynamics at varying spatial and temporal scales in two diverting terrestrial environment. Two pattern-based investigations, one case study in a forest region in Central Europe and another in a semi-arid region in Central Asia, were aimed to answer the main research question "what are the responses of hydrological dynamics and the related hydro-geochemical conditions to climate change and certain changes in LULC at a basin-scale?". The long-term hydro-climatic dataset was used for conducting statistical analyses and establishing hydro-climatic modelling at the basin scale. We further conducted process-based studies, attempting to understand how and why the specific hydrological dynamics were altered at smaller spatial and temporal scales: (i) a catchment-scale tracer-based...
