Production of magnetic particles by microorganisms
Chvalkovská, Eva ; Mgr. Martina Mikešová, Ph.D. (roz. Pravečková) (referee) ; Trachtová, Štěpánka (advisor)
This thesis focuses on the magnetic nanoparticles produced by bacteria. These are two types of bacteria. First of them we can find in an industrial environment that produce magnetic nanoparticles using magnetosomes. Magnetosomes are units containing nanocrystals and are surrounded by a lipid layer. They are made up of chains and work as a compass. In this thesis I deal with possibilities of cultivation od these bacteria, acquisition of magnetosomes and subsequent processing. The second type is bacteria living in the human body, they start to produce magnetic nanoparticles after the addition of trigger, such as silver nitrate. Bakteria which can produce silver or ferrous nanoparticles are Bacillus sp, Escherichia coli, Lactobacillus casei ssp. casei and Lactobacillus fermentum. Experimental part of bachelor thesis focused on the production of silver nitrate in concetration of 0,1; 1; 2; 4 mM. The bacteria that have been shown to produce silver nanoparticles are Lactobacillus casei ssp. casei CCM 7088T a Lactobacillus casei ssp. casei CCM 7089 a Lactobacillus rhamnosus CCM 1825T.

The occurrence of domestic and wild forms of the camels in the old world and their economic use
Burgerová, Michaela ; Gardiánová, Ivana (advisor) ; Jan, Jan (referee)
Genus camel (Camelus) includes two species, the Dromedary camel (Camelus dromedarius) and Bactrian camel (Camelus bactrianus). Camels have a wide range of utilization. People in Arabia countries but also in India and Egypt are using camels as a milk and meat animal, or even as a transport and companion animals and riding animals too. The aim of this thesis was to find sources about camel keeping and using and his role of farm animal in different cultures and countries. And about conditions and requirements in captivity. The first part of thesis contains information about phylogeny and origin of the camel family, taxonomy of camels, short information about the history of domestication and using of camels. There are also described the two species in terms of species biology etc. plus a brief mention of camel hybrids and camel breeds. The second part focuses on the use of camels. The preffered and most common use is in the production of milk, other dairy products from camel milk, fermentation of milk. Another use is for meat performance, meat composition, describes products. His utilization i also useful for other parts such as hair wool and mane, they come mainly from bactrian camel (Camelus bactrianus). The last is working utilization of camels, carrying baggage. Then hobby use. The thesis describes the conditions of keeping camels in captivity, keeping camels in Somalia, requirements for the supply of water and food, housing conditions in the Czech Republic, it is particularly widespread keeping camels in zoos. In Czech Republic they are small private camel breeders. For comparison they are conditions for keeping camels in captivity in Australia.

Legal issues of waste sorting in the Czech Republic in 2015
Pinkasová, Monika ; Kadlecová, Eva (advisor) ; Pavla, Pavla (referee)
To analyze a current legislation of waste management is the main aim of this diploma thesis. It is focused on sorting of municipal waste. Theoretical part deals with historical development of waste management, a present Act on Waste and other special legal regulations. Attention is paid to the Act amendment which includes new obligations about sorting metal and biodegradable municipal waste from January 2015. The next part of this thesis predicts the legislation progress and waste sorting in the future. The results of two surveys are interpreted then. The first one affects public opinion and activity in the sorting of metal and bio-waste. The next one monitors the attitude of municipalities to their new legal obligations in waste treatment.
The survey found that one third of citizens does not know new waste sorting methods, so they do not engage in sorting of metal neither bio-waste. There were identified the worst segments, women and young people 18-29 years old. The next detected problem is that the municipalities use a Civic amenity sites in many cases, which are in a great distance from the citizens. There shall be taken new waste-policy measures in the Czech Republic, within this will not be achieved the EU targets for the year 2020.

The use of solar collectors in the Czech Republic
Kočka, Jan ; Kic, Pavel (advisor) ; Vaculík, Petr (referee)
The aim of this thesis was to approach the market of solar systems in the Czech Republic and the subsequent design of the solar system in the selected object, in this case RD Divišov. In the chapter Overview of the findings from the literature there are outlined the general knowledge about the Sun and the use of solar radiation. In addition, this chapter provides a general overview of solar collectors followed by the approach of the necessary elements for the functioning of the solar systems. In the chapter Default conditions of the solved object there is characterized the selected one, and there is described the current system in this object. Chapter The design of the solar system in a given object includes the proposal of individual elements of the solar set for water heating. There are compared variants with different demands, different input parameters on the basis of values and graphs chosen the most efficient option for this project. At the end, the economic evaluation of the proposed system with the subsequent comparison with the current system and possible return. The work is ended by summarizing of the whole issue.

Jumping Finite Automata and Transducers
Hrubý, Juraj ; Burgetová, Ivana (referee) ; Meduna, Alexandr (advisor)
The bachelor's thesis builds upon the study of jumping finite automata and introduces jumping finite transducers. Jumping finite automata are finite automata modified in such a way that symbols from the input tape are not read continuously from left to right but that the reading head can make moves on the input tape by jumps. Jumping finite transducers are finite transducers modified in a very similar way. In order to implement jumping finite automata and transducers, strictly deterministic versions of them were introduced by restricting the finite state control and by modification of the binary jumping relation. The thesis furthermore focuses on possible usage of jumping finite automata and transducers and on the description of the implementation of strictly deterministic jumping finite automata.
