Intracellular and intercellular regulation of gene expression in Gram-positive bacteria.
Pospíšil, Jiří ; Krásný, Libor (advisor) ; Lichá, Irena (referee) ; Malínský, Jan (referee)
Bacteria, the most dominant organisms on Earth, are an everyday presence in our lives. Symbiotic bacteria, which are present in the digestive tract of animals, usually have a beneficial effect on the body. On the opposite side of the spectrum are pathogenic species that cause more or less serious diseases around the world. In order to fight pathogens effectively, it is necessary to learn as much as possible about the molecular mechanisms by which bacteria respond to their environment, and also about the types of communication within bacterial populations that allow them to react to environmental changes as "multicellular" organisms. This Thesis consists of two main parts. In the first part, selected aspects of bacterial gene expression are characterized, using Bacillus subtilis and Mycobacterium smegmatis as model organisms. DNA-dependent RNA polymerase (RNAP) is the enzyme that is responsible for transcription of DNA into RNA, and thus plays a key role in gene expression. This Thesis deals with the structure of bacterial RNAP and important auxiliary factors (proteins and RNA) that associate with this enzyme and modulate its function. In the second part, the focus is on cell-to-cell communication, revealing which factors/mechanisms, including gene expression, affect this process in B. subtilis....
Utilization of compressor waste heat into the district heating system by means of an absorption heat pump
Aranguren Campos, Fabian Alexis ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
With the growth of energy consumption and the optimization of industrial processes worldwide, new energy sources have been explored and investigated. Waste heat is a potential source for the generation of electricity and heat. This heat can be reused at different stages of industrial processes by using absorption heat pumps, which transfer thermal energy from a location with a lower thermal potential to a location with a higher thermal potential. This research work is basically focused on the evaluation of different absorption heat pumps implemented in the SAKO Brno incineration plant. To carry out this purpose, a bibliographic review of this technology has been carried out worldwide, then the mass and energy balance in the compressor is presented, from which the waste heat to be recovered with the pump will be obtained. Using the EES software, the mass and energy balance of the selected pumps is performed, then the amount of heat and electrical energy generated by the plant when implementing each of the pumps is shown, and finally the economic analysis is presented The design and implementation of a heat exchanger in the system is also included as an essential part of improving operation. The best option arises from the highest operational efficiency at the lowest possible cost.
Impact of Operation Parameters on Fine Combustion Particles Concentration in the Flue Gas of Biomass Boilers
Poláčik, Ján ; Masaryk, Michal (referee) ; Adamec, Vladimír (referee) ; Pospíšil, Jiří (advisor)
This work deals with the impact of operating parameters on fine combustion particles formation in the flue gas of biomass combustion device. The research part of the work describes the properties of fine particles, its basic division, impact on human health and the environment. The basic knowledge of the influence of biomass combustion process on fine particles production up to 1 µm in size is summarized. The main part describes the experimental setup for evaluating the size distribution of fine particles. The following section describes the experimental setup with measured results for various combustion parameters in laboratory combustion, automatic boilers, as well as in the manual wood-burning combustion device. The main parameters which were tested were combustion temperature, oxygen amount, type of fuel and geometry of the burned biomass. The impact of individual parameters on the formation of the fine particles is evaluated. The final part of the thesis summarizes the ways in which it is possible to significantly influence the emissions of fine particles by the appropriate choice of combustion operating parameters.
Financování hospicové paliativní péče v České republice
Pospíšil, Jiří
The diploma thesis deals with the issue of financing of hospice palliative care in the Czech Republic. The aim of the thesis is to evaluate the economic demands of particular palliative care providers with a closer focus on hospice facilities and to propose recommendations for the change of legislation. The theoretical part defines the basic concepts of palliative and hospice care and describes the existing legislation and hospice care abroad. The analytical part focuses on the description of incomes and costs of inpatient and home hospices, financing of hospice care abroad and other aspects affecting the hospice’s economy. Based on the findings and qualitative research carried out, recommendations leading to a possible improvement of the hospice financing system are set.
Cooperation of heat pump and photovoltaic power plant
Gregorovičová, Eva ; Brázdil, Marian (referee) ; Pospíšil, Jiří (advisor)
The bachelor's thesis assesses the heating system of a family house with a heat pump, which cooperates with photovoltaic power plant with storage heat and electricity. The theoretical part describes the main components of the system – heat pump, photovoltaic system, electricity accumulator and heat accumulator. The practical part calculates the energy requirements of the building and describes the proposed system, including the scheme.

Hydrogen for Power
Kocman, Lukáš ; Pospíšil, Jiří (referee) ; Skála, Zdeněk (advisor)
The increasing use of hydrogen in modern energy, has become the motive for writing this work. The work is focused on hydrogen energy and its aim was to compile an overview of hydrogen production technologies, the use of hydrogen technologies in current energetics and the use of hydrogen to energy accumulation. In addition to describing current hydrogen technologies, this work also includes examples of hydrogen devices and projects that we may encounter today. An overview of the above-mentioned technologies has shown that, despite some of its shortcomings, hydrogen has a significant application in current energetics, that is expected to increase in the coming years.
Rock heat accumulator
Nguyen Khac, Hoang ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
The aim of the thesis to explain the functionality of seasonal accumulation with an in-depth view on rock bed accumulator. The computational model is based on the project located in Attenkirchen, Germany. After the technical analysis of the model is carried out an economical review can be realized. To conclude the thesis an evaluation is made comparing an accumulation system with a more traditional one.
