Air pollution model development for complex terrain and it´s application to KRNAP
Jaňour, Zbyněk ; Bílek, V. ; Holpuch, J. ; Kozel, K.
A sopfisticated eulerian dispersion model consisting on numerical solution of flow and diffusion equations on limit area is introduced. The model is applied to the Giant Mountains.
Physical modellling of air pollutant distribution by laser photoacoustic spectrometry in a wind tunnel
Civiš, S. ; Zelinger, Z. ; Jaňour, Zbyněk
In this work we used the laser photoacoustic detectiopn as an analytical tool for monitoring methanol concentration in a wind tunnel. Methanol was chosen as a tracer substance simulating the pollutants. A simple model of a street canyon together with permeation source of methanol vapour was used in various measurements of cross-section profiles. The distribution an concentration of simulated air pollutions has been studied in the street canyon model as a function of the wind velocity.
Deposited precipitation in the Bohemian Forest
Tesař, Miroslav ; Šír, Miloslav ; Fottová, D.
Contribution deals with an observation and evaluation of occult precipitation in the Bohemian Forest (=Sumava Mts.). Although occult precipitation is less important type of the wet deposition from the quantitative point of view, this so-called horizontal precipitation represents important input of delivered matter into many mountainous and urban areas.

Medková, Kateřina ; Jeníček, Vladimír (advisor) ; Abrhám, Josef (referee)
This thesis deals with certain environmental problems in Europe and with attempts to solve these environmental problems within the framework of the European Union. The purpose of this work is to make its readers acquainted with the scope of the EU environmental policy and Community legislation on the protection of the environment. The thesis is focused on four main subject-matters: (i) climate change as a consequence of the global warming process, (ii) air pollution and the ozone layer depletion, (iii) water contamination and (iv) soil degradation. The issue which of the environmental problems require a regional approach and which a global approach is also considered in the thesis.
The importance and utilization of LPG in transport
Binderová, Vanda ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
The importance and utilization of LPG in transport - just the title signifies what is this bachelor thesis focused on. The first part gives a chance to learn more about liquified petroleum gasses, i.e. LPG. It comprehends information about its history, compound, processing, features and also advantages and disadvantages related with this gas. The second part is concerned with the relationship "LPG and environment". You can find there answers to questions like: Why does transport have a negative influence to environment? Which substances are emitted by fuel combustion to atmosphere? Is LPG regardful of environment? The third part is an economic one. It contains the calculations of LPG purchase costs and their economic return and also the price comparison to another fuels. The main aim of this thesis is to compare LPG with petrol and diesel oil and analyze its environmental and economic efficiency.
Air pollution control and its development in town Teplice
