Analysis the quail performance
RYBNÍČKOVÁ, Karolína
The goal of the bachelor thesis was to assess the quail performance. Production and reproduction characteristics are affected by both genetic and environmental effects. Nutrition, temperature and air humidity, light, air quality and floor space are ranged into them. The laying quail performance of commercial-type Japanese quail is about 300 eggs per year, with an average egg weight of 10 g. The protein content is 13.1% and the fat content is 11.2% in one quail egg. Quail eggs have a very favourable amino acid composition and they contain iron, phosphorus and vitamins A, B1 and B2. The meat has a higher content of myoglobin and darker organic pigments. The meat protein content is 22.9%, the fat content is 1.7?2.9% and the mineral content is 1.1%. The energy value of the breast muscles is 24.57 MJ and of the thigh muscles is 27.15 MJ. The dressing percentage in males is 64.8?65.7 % and in females is 74.8?75.9%.

Philosophy of Hope
Malá, Adéla ; Hogenová, Anna (advisor) ; Drozenová, Wendy (referee)
In this work I am looking for a hope in selective authors. This work is divide to five chapter. In first chapter treat about philosphy of hope in conception by G. Marcel. In short foreshadow his autobiography, what about sources of information leaned, what upon philosophy reassume and why occupy oneself by this question. In Marcel I target the hope from ill and dying, bud too the essence philosophy and her relation to freedom. In second chapter I target the especially on the authors theology hope, where is criticism some Utopian imaginings, but also a biblical motivation of hope for survival. I occupy oneself by hope in religion and too foreshadow relation art and hope. Following third chapter is about environmental hope, which are as practical product (on safe groceries, on water and fresh air for all people, etc.). The fourth chapter is about sense of life hopes, hard situations hopes and energy of hope face up injustice.

Ground Heat Exchangers - Operating States and their Influence on Microbiological Hazards
Kolbábek, Antonín ; Klánová, Kateřina (referee) ; Kratochvíl, Zdeněk (referee) ; Jaroš, Michal (advisor)
This thesis deals with the Air to Ground Heat Exchangers (AGHEx) and their effects on the hygienic quality of the supplied air and the microbial microclimate in the interior of buildings. The theoretical part focuses on current findings and knowledge in the field of warm air heating, ventilation of the low-energy and energy passive houses and ground heat exchanger for the ventilation systems to family houses. The next chapter deals with the quality of the indoor environment and the influence on HVAC systems on the building microclimate. The experimental part of the thesis presents the results of energy simulations of operation of air to ground heat exchanger, obtained using the simplified model, and the data from long-term monitoring of experimental AGHEx built at FME BUT. Furthermore, the results of microbiological research of several already operating air to ground heat exchangers are evaluated. The research was carried out using two different sampling methods: the method using swabs taken from the pipe wall, and the sedimentation (gravimetric) method. The conclusion part mentions the practical experiences of users and knowledge of the author relating to the design, operation and use of air to ground heat exchangers.

Effect of various plasma sources on seed growth. Laboratory experimen in Buckwheat
Šerá, Božena ; Gajdová, Iveta ; Čermák, M. ; Gavril, B. ; Hnatiuc, E. ; Kováčik, D. ; Kříha, V. ; Sláma, J. ; Šerý, M. ; Špatenka, P.
Germination and early growth of buckwheat (Fagopyrum aesculentum) after low-temperature plasma discharge treatment in air gas generated in various apparatus were tested. Three pretreatment times were used: 180 s, 300 s and 600 s. Number of germinating achene, length and weight of sprouts were measured. The data was analysed with two-way ANOVA. A significant influence of the type of plasma apparatus, time of exposure and combination of both factors were found. The positive effect on germination and early growth was observed after application of GlidArc plasma. The opposite effect of PDBV apparatus, which is characterized by plasma with a high power density, was observed. Shorter pre-treatment times for this apparatus must be therefore used.

Development of wireless rumen probe
Šídlová, Ludmila ; Matěj, Zdeněk (referee) ; Fedra, Zbyněk (advisor)
The aim was to study the possibilities of wireless transmission from the stomach of ruminants and to design and implement wireless ruminal probe. The first part deals with the internal wireless probe. The next section describes and evaluates available ruminal probe. There is given its own equipment design in the other chapters. The probe was designed for power management and for working with harvestable ambient power. The frequency of 125 kHz with bipolar coding was chosen for wireless data transmission. Two air coils are used on both sides as antennas. The proposed probe was designed and wireless data transmission was tested.

Heating using renewable energy sources
Fornůsek, Patrik ; Počinková, Marcela (referee) ; Horák, Petr (advisor)
My diploma thesis deals with heating with the aid of renewable energy sources and thier application in the building of elementary school. This thesis is devided into three parts. The first part is theoretical and is focused on overview of renewable energy sources. It deals with biomass boilers and heat pumps in detail. The second part of this thesis contains comparison of two variants of heat sources and necessary calculations and designs. The first variant is an air-to-water heat pump and the second one is a pellet boiler. The chosen variant is elaborated in detail in the last part. The last part contains technical drawings and technical report.

Application and evaluation of energy enthalpy heat exchanger
Jetelina, Michal ; Horák, Petr (referee) ; Uher, Pavel (advisor)
This master thesis is solving measuring the efficiency heat recovery and application unit, which includes heat recovery into selected building. In the first part of the thesis are analy-zed the different types of heat recovery system, their behavior and suitability of use in HVAC systems. The second part includes the actual experiment, when were measured parameters of air, which passed through the unit and then were analyzed the results. In the last part, third, was measured unit applied to the selected house and was compared to operation of the unit in case of use by the producer given unit parameters and measured parameters.

Scanning thermal microscopy of thermoelectric pulsed laser deposited nanostructures
Vaniš, Jan ; Zelinka, Jiří ; Zeipl, Radek ; Jelínek, Miroslav ; Kocourek, Tomáš ; Remsa, Jan ; Navrátil, Jiří
New materials with high possible figure of merit ZT are of high interest as a promising candidates for thermoelectric applications such as energy harvesting. Miniaturization of such systems tends toward developing of the suitable characterization method with nanometer resolution ability. In our contribution, we present the development and experimental results of a simple scanning probe microscopy method for the relative thermal conductivity characterization. The possibility of the setup is demonstrated on the set of different thin thermoelectric layers grown from hot pressed targets by pulsed laser deposition on the reference Si substrate. All the measurements were performed on the commercial Veeco Multimode scanning AFM/STM microscope with home developed controller and by using PicoCal Inc. bolometer probes with tungsten resistive path. All the experiments were done in the air at the ambient condition. Additional sample treatment for the measurement will be also briefly described
