Urban, Jaromír ; Látal,, Milan (referee) ; Biela, Renata (advisor)
The subject of the diploma thesis is to introduce the problems of communal spas, namely the treatment of water for swimming pools. Following is a proposal of reconstruction of the treatment plant for a real, operated area of the summer swimming pool. The thesis is divided into theoretical and practical part. At the beginning of the theoretical part I make research of the history of balneology, the effects of bathing and swimming on the human body, possible resources for spa purposes and hygiene requirements for these waters. I also describe commonly used methods of treatment of swimming pool water. In the practical part I first describe the summer swimming pool in the town of Břeclav. There is a description of the swimming pool, its history and equipment. In the next chapter I present the currently operated technological line. Based on a personal visit, the next chapter evaluates the technical condition of the plant. Based on this evaluation, a new technological line for treatment of swimming pool water of the Břeclav summer swimming pool is proposed.

Device for magnetic stirring of suspension with ferromagnetic particles
Zítka, Jan ; Knobloch, Jan (referee) ; Červinka, Dalibor (advisor)
The aim of this work deals with the design and manufacture of a device for mixing of magnetic beads in solution by magnetic field. It is based on my previous bachelor thesis, where the device was created for one microtube (one sample). In this following work, the three improved variants for mixing and separation of 96 samples at one time were designed. The first variant of device, derived from functional prototype from bachelor thesis, was manufactured. First, the magnetic circuit and power converter were designed. Subsequently, the device was manufactured just for one microtube due to functionality testing. The third variant was realized only experimentally, the construction was designed in CAD program, and individual parts were created using 3D printer. As an alternative solution, which should be the compromise among electromagnetic and mechanical stirring, additional prototype was manufactured using 3D printer and CNC instrument. This prototype utilizes neodymium magnets and a stepper motor. The capability of magnetic beads mixing in solution was verified.

Detekce nukleových bazí pomocí kapilární elektroforézy
Hendrychová, Kateřina
Capillary electrophoresis (CE) is one of the most important techniques used for high-throughput separations in modern analytical chemistry. Its main advantages include the possibility of using different detection techniques, speed and efficiency of separation as well as reproducibility. These properties are used in the separation of a wide variety of analytes ranging from inorganic ions to nanoparticles and were also verified in this work, in which the basic building blocks of DNA and RNA, nucleic bases, which serve as biomarkers for many disorders, diseases and food safety, were measured using capillary electrophoresis with a UV detector. The bachelor thesis is focused on the development and optimization of a method to detect and separate 5 nucleobases and purine. The separation was achieved by using 40 mM borate buffer pH 9,8 with the addition of 60 mM SDS as a detergent which forms micelles.

Analýza odpadového hospodářství ve vybrané obci
Škrobánková, Sára
The presented diploma thesis deals with the analysis of waste management in the city of Brno. The introductory part focuses on legal regulations that are related to the problematics of waste generated in the territory of the municipality. Furthermore, the work presents global, European and national trends in the management of municipal waste, the collection network and the costs of waste management within the Czech Republic. In the practical part are evaluated demographic conditions of the city, fulfillment of selected legal requirements of the relevant legislation, efficiency, collection systems, production of individual wastes and their management, economy of waste management and carbon footprint of wastes. Subsequently, a SWOT analysis of the city's waste management was also done. Based on the results, a discussion was written, and suggested measures were written as well to improve the current waste management system. The performed analyzes are processed in charts and tables for better clarity.

Treatment of thickened sludge from industrial wastewater
Peťovský, Patrik ; Procházková, Michaela (referee) ; Vondra, Marek (advisor)
The aim of the thesis is to present the problem of industrial sludge treatment and to identify and implement in laboratory conditions a suitable technology for the treatment of a specific industrial sludge, which is already partially thickened fermentation residues from the operation of biogas plants (BPS). Based on the research developed on available technologies for the treatment of waste sludge, the mixed evaporator was selected as a suitable technology. The advantage is the possibility of using the low potential heat from BPS CHP units under reduced pressure, which is often thwarted. The agitator in the evaporator ensures homogenization while increasing densification. The use of the technology results in a reduction in the volume of fermentation residues. The main part of the thesis deals with the design and implementation of a stirred evaporator for production. Experimental The plant was constructed on the premises of the LENP (Laboratory of Energy-Intensive Processes) at the Brno University of Technology. During operation, the functionality of the device and its applicability to several types of waste sludge were verified. The experimental results are mainly focused on the properties and behaviour of the fugate, or liquid fraction, of the fermentation residues. The fugate was concentrated from a raw state of 5.4 % dryness to a value of 20.9 % dryness, at which point it becomes a highly viscous and poorly flowing material. In an industrial plant where waste heat is wasted, a stirred evaporator may be a suitable device for sludge treatment or volume reduction. This leads to lower costs for storage, transport, and application as fertilizer to fields. With a suitable evaporator and agitator design, the evaporation principle can be used for less and more concentrated waste sludge. The resulting thickened product can then be fed to the finishing operations, allowing the distillate to be finished.

Social Exclusion of Bereaving Parents
KUCSAROVÁ, Šárka
The bachelor's thesis deals with the topic of the social exclusion of bereaved parents. The main objective was to identify the causes of voluntary isolation to the social exclusion of bereaved parents. A sub-objective was to map the specifics of communication between bereaved parents and their environment in the first year after the child's death, from the perspective of the bereaved parents. The thesis is divided into theoretical and practical parts. The theoretical part is devoted to a study of the available literature on death, bereavement, and social exclusion with a focus on bereaved parents. The practical part maps the differences in the communication of the bereaved parents with their environment in the period after the loss of their child, and also identifies what reactions to the environment had a positive and, on the contrary, negative influence on the communication style of the bereaved parent. Finally, it examines the influence of the reactions of the environment to the bereaved parent's child loss in terms of social perception. To achieve the aim, a qualitative research strategy based on semi-structured interviews was chosen. The thesis provides a probe into the mode of communication between bereaved parents and their environment and the changes that this communication undergoes during the first year after the child's death. The contribution of the thesis is the information depicting the attitude of the social environment towards bereaved parents, the reasons for this attitude, and its impact on bereaved parents. The thesis reveals the scope for educating society on communication with bereaved parents and highlights the grey area of care for grieving parents within social policy.
