San Minn (or) An Artist who prefer creating and paintings than his life
Zeya, Pyin Nyar ; JANEČEK, Vít (advisor) ; VOJTĚCHOVSKÝ, Miloš (referee)
No one can control a painter artist’s freely thoughts and ideas and although his paintings were under the high pressure and banned by force, the artistic value of his materials never go down. So that I am writing this paper. He, San Minn has broken out the mainstream of Burmese painting field, he never made business paintings as well. He keeps his belief on the art of paints and he is always finding for the new way to make his paintings. His materials are very different from other Burmese painter artists’ materials. His style is unique in Burmese paintings. So I can get a chance to study of his style, ideas, ways of thinking and his determination on the art works. My paper can show a painter artist’s life who grew up under the military rule for 50 years and the situation and history of Burmese painting field. Then not only people who are studying the painting subject, but also other people can know about the subject of Burmese painting and field of artists. I dare say that my paper must be colorful and fruitful. As a painter artist, it seems that he wants his audience to feel his materials but he rare to show his real life behind the pictures. For me, I can get a chance to know about his real life for my thesis paper. xxxxxxxxxx Thesis Statement My thesis can be useful for everybody who is interested in Burmese contemporary art field. This is the biggest chance to read about one of the most famous, important and significant artists and art movements of Burma. His paintings are reflecting his journey through over 40 years of censorship, but he was not afraid to tackle political and social issues. Many of San Minn's art works are based on autobiographical, making sharp social commentary on the popular culture, social values and scenario circumstances where he has lived in. xxxxxxxxxx

Use of inhalation systems with asthma in connection with nursing
KLEINOVÁ, Irena
Asthma bronchiale is a chronic inflammatory disease of the airways, connected to bronchial hyperactivity leading to shortness of breath, wheezing, chest tightness and cough. It effects people of all age categories and cannot be efficiently cured nor prevented. The incidence ranks this disease among the most common children´s chronic diseases. It affects a significant part of the global population - records say about 300 million people. Its prevalence has dramatically increased over the last 20 years. It is estimated that in 2025 about 400 million people will suffer from asthma. Cornerstones of asthma control are based on early diagnostics, efficient treatment, adherence to lifestyle changes and proper use of inhalation devices. Once the treatment is effective and check-ups and the use of inhalation therapy are regular, the prognosis of asthma is very favourable and it is possible to improve the patient´s quality of life. The control over asthma and its maintenance is the main objective of treatment. This can be achieved by using anti-inflammatory therapy, especially in inhalation form. This Bachelor´s thesis focuses on mapping inhalation systems with patients with asthma bronchiale. To a large extent it deals with the issue of use of inhalation systems, keeping to lifestyle changes and the role of the nurse in asthma-specialized outpatient´s departments. We see the relevance of this topic in the fact that, despite all available literature and medical advice, many asthmatics still make mistakes in the inhalation technique. Wrongly selected inhalation systems or wrongly selected inhalation techniques results in therapeutic failures and problems of patients get worse. This does not maintain control over asthma. The fact that many asthmatics do not know their exact diagnosis and underestimate some symptoms is very alarming. In the introduction, the theoretical part focuses on the definition of the disease. Other chapters include causes and symptoms of asthma, its classification, diagnostics and treatment. It also provides information about the treatment of acute asthma attacks - exacerbation and the role of the nurse in examination of an asthmatic patient. A great part of the thesis deals with inhalation systems, their types and effects. The preparation for the use of manual handheld inhalers and nursing care for the asthmatic patient in outpatient and inpatient care is developed at the end of the theoretical part. The objective of this part was to summarize the current knowledge about this issue. The objective of the Bachelor´s thesis was to map the use of inhalation systems in patients with asthma bronchiale. The following research questions were used: How do nurses inform patients about the use of inhalation systems? What type of inhaler do patients like? What is the nurse´s involvement in the examination of asthmatic patients? What are the most common mistakes in the application with an inhaler? How do asthmatics keep to lifestyle changes? The practical part of the thesis contains the results of qualitative research which was made on the basis of the semi-structured interview. Final interviews were transcribed and subsequently processed by the technique of open coding. The research sample was made of 12 asthmatics and 9 nurses working in selected asthma-specialized outpatient´s departments. With respect to the results found, an information brochure was created - see Annex 7 - which is intended for use by asthmatics. We believe that the results of this thesis will be helpful for asthmatics and increase the interest of experts in this issue and will also address other people willing to take part in its solution.

Fluidized-bed Combustion of Dry Stabilized Sewage Sludge in Oxy-fuel Mode
Moško, Jaroslav ; Pohořelý, Michael ; Durda, Tomáš ; Zach, Boleslav ; Šyc, Michal ; Svoboda, Karel
Sewage sludge is an inevitable waste stream from wastewater treatment and its disposal is complicated due to specific characteristics of its composition. Sewage sludge combustion/incineration is the only suitable way for disposal of large volumes of sewage sludge containing POPs and some heavy metals. Sewage sludge combustion reduces the volume of such waste and causes destruction of organic contaminants. Oxy-fuel combustion is a technology for simplifying CO2 sequestration from the flue gas by using nearly pure oxygen instead of air for the combustion. In order to control the combustion temperature, part of the flue gas is recycled to combustion chamber. The paper brings information about investigation of the effects of combustion temperature and concentration of oxygen in inlet combustion media on the emissions of NOx, N2O and SO2 in FB combustion of sewage sludge. The experimental results have shown that an increase in combustion temperature leads to an increase in NOx and to a decrease in N2O emissions in the temperature range 750–930 °C. The lowest SO2 emissions were measured in the temperature interval from 800 to 820 °C in all experiments with different oxygen concentration in inlet gas. It was found that when the oxygen concentration in inlet gas increased, the emissions of SO2 increased while emissions of NOx slightly decreased.

Plášková, Pavlína ; Toušová, Renata (advisor) ; Ducháček, Jaromír (referee)
The aim of this thesis is to evaluace the conditions of dairy cattle breeding in ecological agriculture and to compare them with concrete values taken from the chosen ecological farm Bílčice, which has been part of ecological agriculture since 2011 and which is focused on czech fleckvieh breeding and bio milk production. The first part deals with dairy cattle breed characteristic, main objectives and ecological agriculture principals, welfare problems, breed cattle and utility control, housing technology, nutrition and feeding, mechanical milking technology, milk production, reproduction, health condition and breeding economy. The practical part contains the rating of milk yield index (milk production, % proteins, % fat) and reproduction index ( meantime, perioda service, insemination index and after first parturition percentage). 650 pieces of cos were stabled at farm, from that 200 pices of dairy cos were mostly czech fleckvieh. Monitoring was made in 2013. Dayily milk production was around 2 750 kg. The milk utility for lactacion was in 2013 6 100 kg of milk, 3,89 % fat and 3,34 % proteins. The dairy cos were free stabled with high bedding, They were mechanically milked twice a day in herringbone parlours. Milk is being delivered once in twodays to Olma dairy. Cows are regularly driven out to pasture in summer feeding period. They are extra fed with 10 kg of clover silage and 6 kg of scarp (barely, wheat, triticale). Cows stays in stables for winter time. The ration consists of 45 kg of clover silage, 6 kg of scarp, 2 kg of lupine and 1 kg of corn in first time of lactacion. The cow utility in transitional form of economy at farm Bilcice was 7 477 kg of milk in 2010, a value in the Czech Republic was 7 726 kg of milk. After entering the ecological agriculture in 2013 milk yield at the farm decreased on 6 100 kg of milk and the average value in the Czech Republic increased to 8 370 kg of milk. The cow utility in transitional form was 4,03 % fat in 2010 and 3,89 % in 2013 (ecological agriculture). A diference between 2010 and 2013 is 0,14 %. Proteins were 3,39 % in 2010 and 3,34 % in 2013. There was average value for every reproduction index. The service period was 96 days and the meantime was 400 days, the insemination index was 1,8 and the after first parturition percentage was 54,2 %.

Nutritional analysis and optimization of breeding of selected species of edible insects under conditions of the Czech Republic with regard to human health
Adámková, Anna ; Kouřimská, Lenka (advisor)
All over the world, the edible insects are considered a highly nutritious food with high protein and fat content. However, the nutritional value of insect is not constant. It can be affected by species, developmental stage, rearing technology or nutrition. Therefore, this thesis was aimed at obtaining the selected nutritional value of edible insects. Analyses were focused on the determination of the crude protein content, fat content, fatty acid profile and sterols in selected species of edible insects, which can be commonly reared in the Czech Republic. At the same time we also analysed samples of insects reared on the island of Sumatra to evaluate the influence of the climate on the nutritional value. The main aim of the thesis was the determination of optimal breeding conditions, developmental stages and feed rations for obtaining good production of insects with nutritional properties suitable for human nutrition. The analyses showed a high nutritional value of selected insect species, but also confirmed the significant differences in the content of individual nutrients between different species depending on the climate conditions and developmental stage. Comparing the fat and crude protein content in edible insects and other conventional sources of meat it has been found, that the examined insect is similar to beef concerning the fat and crude protein content. The results obtained are the basis for determining the appropriate rearing conditions and developmental stages for obtaining insect with the desired nutritional properties for human nutrition.

Freezing technology of bull sperm in relation to its survivability and fertilization ability
Doležalová, Martina ; Stádník, Luděk (advisor) ; Jiří, Jiří (referee)
The aim of optimalization the insemination doses production is to provide the highest fertilization ability of spermatozoa during the demanding proces of processing fresh semen and its subsequent cryopreservation. Temperature changes causes spermatozoa damage during the cooling and freezing. Spermatozoa is exposed to cold shock and many others limiting factors, which leads to cell death and therefore to decline of fertilization ability of thawed insemination doses. For increasing spermatozoa resistance, exactly the plasma membrane resistance against cold shock was fraction of egg yolk LDL cholesterol (low density lipoprotein) at various concentrations into the comercially produced diluents added. It is believed that LDL acts possitively to plasma membrane and helps to maintain the fertilization ability of spermatozoa after thawing. Following step in the proces of insemination doses production is slow cooling of diluted semen and equilibration, when the straws are store at cooling box for 30 minutes to 240 hours. This period is necessary to penetrate of certain diluent components into the spermatazoa also maintain the balance between their intracellular and extracellular concentration. Also important is subsequent freezing temperature gradient of insemination doses. The most suitable freezing method is based on computer controlled temperature decline in freezing chamber which allows the precise control of ice crystals formation that could tear and kill the cell. During 2012 to 2016 was repeatedly collected semen from the group of breeding bulls (n = 27, Holstein and Czech Fleckvieh breed) at AI centre. Semen which fulfill the standard entrance conditions in first step was evenly into several parts divided. For dilution the three types of comercially diluents AndroMed, Bioxcell and Triladyl with and without LDL addition were used. Into the diluents AndroMed and Bioxcell the concentration of LDL 4 %, 6 % and 8% into the dilent Triladyl 6 %, 8 % and 10 % was added. Diluted semen was filled into the glass capillares with volume 0,1 ml and temperature +4 °C. Subsequently the sample was placed to cold bath (0°C) for 10 minutes. Then the volume of capillare with physiological solution (37 °C) was mixed and for next 120 minutes was incubate. The effect of cold shock to proportion of live spermatozoa was evaluated by using Eosin and Nigrosine staining technique during heat test of spermatozoa survivability after spermatozoa heating and after 120 minutes of incubation. The more suitable semen diluents which provide the higher spermatozoa resistance against cold shock were AndroMed and Bioxcell. Together the possitive effect of LDL addition into the diluents to lower decrease of proportion of live spermatozoa during heat test was found (P<0.05). The most suitable LDL concentration which had a favorable influence at spermatozoa resistance against cold shock was 6 % in diluent Bioxcell. Values of the proportion of live sperm were higher at the beginning of the heat test (+1.31% to + 3.2%) and after 120 minute incubation (+5.82% to +8.41%) compared to other diluents with and without addition of LDL. In the next step the process of equilibration was optimized, is an important part of insemination doses production. The effect of the length of equilibration for subsequent fertilization ability of spermatozoa was evaluated using spermatozoa motility based of CASA and proportion of live spermatozoa after thawing and during heat survival test lasting 120 minutes (37 ° C). Suitable semen was diluted by comercially used diluent AndroMed based on soya lecithin, filled into the straws (0.25 ml), cooled and equilibrated in cooling box for 30, 120 and 240 minutes and freezed in programmable freezing box applying four types of freezing curves differing in temperature rate decline. There was used standard and by producer recommended 3. phase freezing curve, then 2. phase freezing curve, and 3. phase freezing curve with slower as well as rapid decline of temperature rate in freezing chamber, compared with standard freezing curve. The highest spermatozoa motility was found using 240 minutes of equilibration by +2.72% and +4.58% compared to other lengths of equilibration (P <0.05 to 0.01). The highest proportion of live spermatozoa was found using 120 minutes of equilibration (+6.87 % and +8.68 %). The highest average spermatozoa motility during heat test after thawing was achieved by using 2. phase freezing curve (from +2.97% to +10.37%, P <0.05), also in the proportion of live spermatozoa (from + 4.37% to +8.82%, P <0.01). When evaluating interaction between the length of equilibration and freezing curve (standard 3. phase and 2 . phase freezing curve), the highest average spermatozoa motility and proportion of live spermatozoa using 240 minutes of equilibration by both freezing curves was reached, there was no statistically significant differences. As well as, in all evaluated parts of this study the individual differences between ejaculate of bulls and within semen from one bull (P <0.05) as secondary effect were found. To maintain good fertilization ability of semen during cryopreservation is necessary to increase the spermatozoa resistance against cold shock using addition of correct concentration of LDL into the commercially used diluents AndroMed and Bioxcell. Subsequently the fertilization ability of insemination dose is influenced by cooling, the length of equilibration and freezing. The length of equilibration 120 minutes and more as well as gentle way of freezing according to freezing curve, which ensures a gradual decrease of temperature in freezing chamber provided the higher average spermatozoa motility and proportion of live spermatozoa.

Bakule, Lubomír ; Papík, Martin ; Rehák, Branislav
DCTOOL-A3 is a documentation of Matlab routines developed for the design of decentralized control of large scale complex systems. The current beta version covers three areas as follows:\nReport 4.1 deals with the event-triggered control design for unstructured uncertain systems. Both non-quantized and quantized feedback is analyzed. The results are given in terms of linear matrix inequalities (LMIs). Logarithmic quantizer is used. Numerical example illustrates the effectiveness of the presented results.\nReport 4.2 presents a new decentralized overlapping wireless control design with a switched communication protocol. The method is applied by simulations on the 20-story building structure including the test of robustness of the methods against sensor failures and network node dropouts of a digital network.\nReport 4.3 presents the construction of a new decentralized wireless controller and a set of heuristic algorithms for evaluation of packet dropouts, sensor faults and actuator faults. The digital network operates at the standard frequency used in well-known widely-used industrial protocols. The results are tested at the Benchmark model decomposed into two disjoint substructures. The results are published. Thus, the details are omitted here.

Black Chromia Plating for the Solar Radiation Absorbers
Brožek, Vlastimil ; Březina, Václav ; Brom, Petr ; Kubatík, Tomáš František ; Vilémová, Monika ; Mastný, L. ; Novák, M.
Black chromia layers were produced on copper, zirconium and aluminium substrates. These layers are aimed to serve as solar collectors. Efficiency of the layers during UV-VIS, UV radiation and WSP® plasma torch radiation is described. The chromia layers were prepared by a new procedure, i.e. deposition of ammonium dichromate solution using plasma torch or so called Liquid Precursor Plasma Spraying (LPPS). Solution of ammonium dichromate is fed into plasma stream, where dissociation takes place under temperatures of 4000 K – 25000 K. Up to nanometric oxide particles can be produced; the resulting size is dependent on solution concentration and feeding nozzle diameter. The particles impact on substrate and form coating. Using 2 wt.% to 5 wt.% solution of ammonium dichromate and feeding nozzle of 0.2 mm in diameter is the size of produced chromia particles about 6 µm which results in formation of 2 µm to 3 µm thick coating, i.e. according to the theory an optimal thickness 2.5 um for absorption layers, necessary condition for formation energy traps for IR radiation emitters up to 100°C. Moreover, black chromia coating is a suitable corrosion barrier of metallic substrates. \n\n

Kubatík, Tomáš František ; Stoulil, J. ; Stehlíková, K. ; Slepička, P. ; Janata, Marek
The most common magnesium alloy AZ 91 is widely used as a structural material, but its use is limited at higher temperatures and high humidity. Plasma spraying is a technology that allows to prepare protective metallic and non-metallic coatings on a wide variety of substrates including magnesium and its alloys. In this study, CuAl10 and CuAl50 were plasma sprayed on magnesium alloy AZ 91 with the aim to study corrosion resistance of the plasma sprayed coatings. The corrosion resistance of layers was evaluated by the method of electrochemical potentiodynamic measurement as well as long-term corrosion tests in a condensation chamber with 0.5 mol\nNaCl at the temperature of 35 °C for 1344 hours. Layers with 1, 2, 5 passes and passes of CuAl10 with the thickness ranging from 75 to 716 mm and CuAl50 with the thickness ranging from 64 to 566 mm were prepared. The increased corrosion velocity was observed in the case of thin layers of 2 and 5 passes due to the development of a galvanic corrosion couple. The CuAl10 layer prepared with ten passes has an outstanding corrosion resistance.

Comparing the Price of a Transportation Structure and the Actual Costs Incurred in Various Stages of Construction
Nezbeda, Jiří ; Zímová, Štěpánka (referee) ; Kosová, Jaroslava (advisor)
This diploma thesis deals with the calculation of the cost of the building work in order to create the price, which at the stage of the contract becomes a selling price, and the costs are fixed as a budget. The subject of this work is to monitor the development of costs in time so that the cost does not exceed the budget and the construction did not get into the negative result. Then set the price by its own methods (item budget, calculation according to budget indicators) and compare the prices and costs thus obtained from different phases of construction between each other and determine the differences. In this work is monitored and compared the cost of a construction contract and its costs in the construction stages. In the practical part,is used the method of direct comparison of cost and price values over time, in the form of different outputs from the controlling program and outputs from compiled item budget and the calculation of the construction. Analyzing the differences between these costs and their evolution over time by more detailed examination of item budgets and cost calculations, they determine the origin of these deviations. In conclusion, is proposed measures for a particular transport structure whitch was handled by the author as"master and co-ordinator of the construction".
