The Russian response to the revolutionary era of the years 1830-31
Svoboda, Karel ; Reimann, Michal (advisor) ; Vykoukal, Jiří (referee) ; Vlček, Radomír (referee)
This thesis deals with the Russian response to the revolutionary era of the years 1830-31, using the theory of defensive realism. Based on archival material and on available literature, it analyzes mechanisms for the adoption of decisions in the Russian political structures. The author approaches the topic with chronological-thematic perspective. The first section analyzes the politics of the Russian tsar and his environment in relation to the French and Belgian Revolutions. The second part is devoted to the issue of Poland. In the third part the author analyzes the internal conditions in the Russian State itself. Last but not least, the author analyzes public opinion, economic conditions and the situation in the army.

Fluidized-bed Combustion of Dry Stabilized Sewage Sludge in Oxy-fuel Mode
Moško, Jaroslav ; Pohořelý, Michael ; Durda, Tomáš ; Zach, Boleslav ; Šyc, Michal ; Svoboda, Karel
Sewage sludge is an inevitable waste stream from wastewater treatment and its disposal is complicated due to specific characteristics of its composition. Sewage sludge combustion/incineration is the only suitable way for disposal of large volumes of sewage sludge containing POPs and some heavy metals. Sewage sludge combustion reduces the volume of such waste and causes destruction of organic contaminants. Oxy-fuel combustion is a technology for simplifying CO2 sequestration from the flue gas by using nearly pure oxygen instead of air for the combustion. In order to control the combustion temperature, part of the flue gas is recycled to combustion chamber. The paper brings information about investigation of the effects of combustion temperature and concentration of oxygen in inlet combustion media on the emissions of NOx, N2O and SO2 in FB combustion of sewage sludge. The experimental results have shown that an increase in combustion temperature leads to an increase in NOx and to a decrease in N2O emissions in the temperature range 750–930 °C. The lowest SO2 emissions were measured in the temperature interval from 800 to 820 °C in all experiments with different oxygen concentration in inlet gas. It was found that when the oxygen concentration in inlet gas increased, the emissions of SO2 increased while emissions of NOx slightly decreased.

Treatment of Flue Gas from Waste Incineration by Sodium and Calcium Based Sorbents.
Zach, Boleslav ; Pohořelý, Michael ; Šyc, Michal ; Svoboda, Karel ; Punčochář, Miroslav
This paper is focused on properties of sodium and calcium based sorbents in relation to simultaneous dry flue gas treatment from SO2, HCl, NOx, solid particles, and polychlorinated dibenzodioxins and dibenzofurans (PCDD/F). The most important differences between the two sorbent types are: the effect of temperature and moisture of flue gas on the sorption process, reactivity towards individual acid components in the flue gas (thermodynamic equilibrium and kinetics), and solubility of air pollution control residues.

Thermodynamic Limits for Dehalogenation of Producer Gas by Na2CO3, NaAlO2, CaO/CaCO3, BaO/BaCO3 and Mixed CaO-BaO/BaCO3 Sorbents.
Svoboda, Karel ; Leitner, J. ; Havlica, Jaromír ; Brynda, Jiří ; Skoblia, S. ; Hartman, Miloslav ; Pohořelý, Michael ; Hsu, H.-T.
Our study is focused on thermodynamic analyses and minimization of Gibbs energy for gas de-halogenation (removal of HCl, HF and HBr) by selected solid sorbents (Na2CO3, NaAlO2, CaO/CaCO3, BaO/BaCO3, and mixtures containing CaO-BaO/BaCO3).
