Solid fuels boilers inovation
Kadlík, Libor ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This bachelor’s thesis deals with combustion in solid fuels boilers. The thesis is divided into three parts. In first part is described sorting and characteristic of solid fuels, types of solid fuels boilers and technology of combustion. In second part are introduced legislative requirements of harmful emissions and responsibility of solid fuels boilers dealers and operators. Final part is concerned with innovations, which are necessary to more effective and less harmful combustion.

Ventilation strategies for block of flats
Tuka, Ján ; Krejčí, Vladimír (referee) ; Hejčík, Jiří (advisor)
This bachelor´s thesis contains a summary of ventilation strategies used for ventilation of block of flats. In the beginning, it includes the list of most common harmful substances which might occur in this space. Next chapters present principles and purpose of ventilation, types of ventilation, characteristics. The principles of self-ventilation and forced air ventilation are described here, the ventilation systems based on these principles and advantages and disadvantages of these systems are mentioned. Also the minimum requirements of ventilation for living space are specified.

Přínos elektricky poháněných osobních automobilů pro snížení emisí oxidu uhličitého ve městech
VOTRUBA, Michaela Hana
Master's thesis deals with the issue of air pollution, to which automobile transport contri- butes extensively. Poor air quality has adverse effects on the health of every human being on Earth, so it is important to work constantly to reduce the emission footprint we leave behind. It is road transport that has a lot of room for improvement. The aim of thesis was to calculate the amount of CO2 produced by passenger cars on a selected section of the road in České Budějovice. And then calculate the amount of CO2, which would leave the same number of electric cars in the same driving section.

Substances present in everyday life representing threats to the health of older-school-age children
Metelková, Iva ; Marádová, Eva (advisor) ; Beneš, Pavel (referee)
TITLE: Substances present in every day life representing threats to the health of older- shool-age children AUTHOR: Iva Metelková DEPARTMENT: Department of Education SUPERVISOR: PaedDr. Eva Marádová, CSc. ABSTRACT This thesis deals with the substances present in everyday life, which may pose risk for human health. In the theoretical part of this work groups of hazardous substances are characterized. For selected representatives of each group are specified. negative impacts on human health and outlines the mechanisms of action. Individual chapter is devoted to physical and psycho-social development of school age students using knowledge of developmental psychology. Substances which on the other way help detoxify the body and help it to be resistant to the effects of potentially hazardous substances are also mentioned. The aim is to map the practical awareness of the hazardous effects of selected substances among pupils attending upper primary school. Questionnaire survey found that students do not attach danger arising from the presence of potentially hazardous substances in foods, cosmeticsand household. Therefore I recommend pay attention to information about risks arising from long term exposure to these substances. KEY WORDS: harmful substance, health protection, food hazards, drugs

Stanovení základních emisí z výfuků osobních vozidel ve vybraných úsecích dopravní trasy
KAHUDA, Jan
This diploma thesis deals with the issue of environmental pollution caused by the production of harmful substances originated from the automobile combustion engines and the calculation of production of basic pollutants emitted from the passenger car exhausts travelling on selected sections of transport route. The aim of the work was to calculate the amount of emitted harmful substances, according to the composition of the vehicle fleet on some selected monitored sections of transport routes. For analysis were selected three stretches of roads in České Budějovice. The analysis considered the vehicle fleet composition, determination of traffic intensity, average speed of vehicles and traffic fluency on the transport routes. The calculated values were obtained using the special software MEFA 13
