The effect of management type on greenhouse gas emissions from grasslands
HAJŠMANOVÁ, Klára
This work represents the grant application for project dealing with the influence of the type of management and fertilization on greenhouse gas emissions of (CO2, CH4, N2O) from grasslands, namely grazed pastures, mown and mulched meadows at an organic farm Borová near České Budějovice. This project evaluates the diurnal gas flux dynamics affected by application of different nitrogen fertilizers (i.e. NH4+, NO3- and manure).

The use of nanotechnology in agricultural production.
BAHENSKÝ, Bohumír
This thesis defines nanotechnology. It focuses on their use in various industries, especially in agriculture. The experiment in this paper is concerned Envirolyte that produces electrochemically activated water. The device was used in raising chickens for meat to disinfect drinking water and thus reduce the emission of gases. Was compared to the reference and experimental hall, which used Envirolyte el-900. Production of ammonia emissions in specific reference lobby is 0,307210 kg / pcs / year and for the experimental hall 0,165054 kg / pcs / year, which is a decrease of 46%. Operation rate is 92,15 CZK / day. Annual operating costs are 23 221,8 CZK and costs of reducing ammonia emissions by 1 kg is 321,8 CZK.

Analysis dependence of the weight concentration of flying dust in the village in relation on the influence of road cleaning.
POSPÍCHAL, Miroslav
The aim of this thesis was to provide a measuring of the weight concentration of flying dust in road traffic in dependence of traffic environment and also the acquirement of objective information about the real influence of roadcleaning. The measuring took place on a regular street in the centre of České Budějovice. At first the dust concentration was measured before the proces of cleaning. Next the street was cleaned by a compact sweepmachine and a second measuring took place. The results displayed, that the roadcleaning has a negative influence on the dust concentration in the air. The weight concentration of the flying dust rose about 50% to PM10= 0,077 mg.m-3. People going along the street were exposed to an excessive encumbarance, which could have in a longtime affect bad inflence on their health.

Atmospheric deposition of nitrogen and phosphorus in the Czech republic and round the world.
SUCHÁ, Jitka
This bachelor thesis is focused on the atmospheric deposition of nitrogen and phosphorus in the Czech Republic and round the world. For easier understanding of atmospheric deposition in the thesis there are shortly explained terms such as the source of pollution, emissions and air pollutants, which are interdependent and often interact. There are presented different types of atmospheric deposition, their detailed classification, their collection and the process of determining the size of atmospheric deposition. Furthermore, this thesis gives the current value of atmospheric deposition in European and non European countries and the values in the Czech Republic, where the trend of atmospheric deposition from the fifties to the present is shortly described. The thesis presents the station network in the Czech Republic, its functions and methods of data collection, which are still used to evaluate the air quality situation in Europe in the EMEP programme, where you can find information about other European countries. Then the values of atmospheric deposition of nitrogen and phosphorus in the U.S., especially on the east coast and central parts of the United States of America, and China are presented. The last part of the thesis is focused on atmospheric nitrogen deposition value development in the Czech Republic selected, more or less affected areas in the Czech republic.

Transport Externalities and Their Solution Possibilities
NEUMANNOVÁ, Veronika
The main aim of my theses entitled Transport Externalities and Their Solution Possibilities was to define transport externalities and to describe the methods of calculating the external costs. My goal in the analysis part was to evaluate the effectiveness of existing measures leading to reduce the height of external costs and to suggest further idea of externalities solutions. Transport activities give rise to environmental impacts (air pollution), accidents and congestions.

Measurement and evaluation of emission gas production in selected cattle operation.
KAŠÍK, Ladislav
Measurement and evaluation of emission gas production in the selected operation with cattle''. This thesis deals with environmental pollution, especially livestock production in agriculture. The work is based on the determination of emission gases NH3, CO2, NH4, and NO2 and water vapor in the barn with redholsteen cattle breeds in ZD Krásná Hora nad Vltavou a.s. This work also deals with ammonia in agriculture, greenhouse gases and methods, which determine their concentrations. Average concentrations of the gases were as follows: CO2 = 1 188, 73 mg. m-3, water vapor = 8 181.29 mg.m - 3, N2O = 0.535 mg.m-3, NH3 = 1.14 mg.m -3; CH4 = 4.81 mg.m-3. The total average amount of all measured concentrations is 9376, 45 mg.m-3.

Charging for road transport in London
Koscelník, Štefan ; Zelený, Lubomír (advisor) ; Kiovsky, Tomáš (referee)
The aim of this work is to describe and evaluate the project of road charging in London. The theoretical part deals the issue of transport in urban conditions, its basic types, problems and possible approaches to tackling it. It also includes a description of the electronic toll systems as tools used to manage traffic in the city. The practical part deals with the use of video detection technology for road charging in London. It includes the preparation and implementation of the project, its basic principles of operation and adjustments made during the period of its operation. Followed by evaluation of the project in terms of impact on traffic, business and air quality in London. At the end of the work there are some recommendations for possible implementation of a similar charging system in terms of the city of Prague.
