The effect of reduction cores on the properties of brick body
Kučera, Tomáš ; Stančík,, Hynek (referee) ; Sokolář, Radomír (advisor)
This diploma thesis deals with creation of reduction core problem mainly in fired roofing tiles. With those is the emphasis on the impermeability and frost resistance. Black reduction core is reducing frost resistance but depends on firing temperature. At 1060 °C the reduction in frost resistance is not as unfavorable as at 900 °C. This thesis includes overview of research conducted on reduction core topic. There is enough literature focusing on frost resistance, experimental part is focused mainly on the impact of reduction core on impermeability and compares two types of production mixtures used in Czech Republic (calcium-containing type from Hranice and non-calcium type from Stod). It includes comparison of mixtures with fluidized fly ash and dust from grinding masonry elements. It opens discussion if those mixtures can be used for reduction core elimination.

Efficiency of Water Treatment Processes Using Activated Carbon
Hladíková, Lucie ; Kolesíková, Lucie (referee) ; Kučera, Tomáš (advisor)
The subject of the thesis is the issue of pesticides in the environment and the possibility of their removal through activated carbon. The thesis is divided into two parts, the search part and the practical part. The research part is focused on description of activated carbon. It also deals with the distribution of pesticides and their degradation in the environment. In the practical part, a laboratory experiment was carried out to determine the effectiveness of removing pesticides and metabolites from the test water on two types of activated carbon.
Genesis of Russian propaganda as a serious security threat of the 21st century from the perspective of NATO and EU
Stejskalová, Jana ; Kučera, Tomáš (advisor) ; Střítecký, Vít (referee)
The thesis entitled "Genesis of Russian propaganda as a serious security threat of the 21st century from the perspective of NATO and EU" examines the phenomenon of contemporary Russian propaganda. Russia commonly uses propaganda as a tool of promoting its interests. Russian propaganda is very sophisticated, aggressive, and massive. Mainly due to the effective use of the internet and social networks, Russian online actors are able, in a short space of time, to successfully generate an information chaos, which is difficult to navigate in. Contemporary Russian propaganda has several key aspects, namely the anti-American and anti-European orientation, attacks on Western democratic values, and the mixing of truth with fiction. Thus, propaganda becomes an effective weapon in the information war that the Kremlin has initiated. The West is aware of these alarming issues and tries to respond. The thesis analyzes the development of the perception of the Kremlin propaganda by the Western international security organizations NATO and EU. At the same time, it attempts to identify the moment when Russian propaganda began to be perceived as a serious security threat. Whereas the key of the analysis is to interpret the perception of Russian propaganda, the concept of securitization was chosen as the theoretical...
From revolutionary armed forces to revolutionary regimes, empirical analysis of the transformation
Cuby, Alexandre ; Kučera, Tomáš (advisor) ; Aslan, Emil (referee)
The purpose of this thesis is to investigate the role that political ideologies plays in determining the target of insurgency movements. In order to understand how these groups operate, I use Janowitz's military establishment to apply it on the three main revolutionary ideologies of the 20th century, Khomeinism, Marxism/Leninism and Fanonian. Based on these analyses, I hypothesize the three main targets by ideology based on the clarity of the indoctrination and on the level of bureaucracy entailed in the revolutionary texts. I then proceed to compare these theories to three case studies, the Hezbollah, the FARC and finally the PKK. I try to offer an explanation on why religious insurgencies target most of their attacks towards rival factions or why nationalist left-wing groups are mostly focused on attacking security forces. I argue that a well-structured hierarchy, a reliance on the civil society and a clear definition of the political and military targets are quintessential to prevent civilian causalities. But contrarily to most papers on the topic, I find that a strict military discipline has the reversed result that expected. For instance, the FARC and the PKK have such a strict internal code of discipline that it led the members to desert the organizations by thousands and have civilians as...
Understanding of hybrid warfare in Ukraine: to what extent this understanding is shaped by its internal experience?

Master thesis Prague 2019 Author: Tetyana Demyanchuk Supervisor: Mgr.

Master thesis. Charles University, Faculty of Social Sciences, Institute of Security Studies. Mgr. Tomáš Kučera, Ph.D. Abstract Hybrid warfare has achieved notoriety of being a buzzword attempting to explain the changes in the modern warfare that blur the lines between war and peace, conventional and irregular warfare. Despite its definitional shortcomings, it made its way into the official discourse of the politicians commenting on the conflict in Ukraine and Russia's involvement in it, which did not add clarity. This thesis aims to bring a Ukrainian perspective to the discussion, and it attempts to provide a deep interpretation of sufficiently...
Securitization of migration in Czech Republic
Lukašík, Petr ; Kučera, Tomáš (advisor) ; Špelda, Petr (referee)
The thesis in your hands focus on foreign Fighter phenomenon in the Czech Republic. It argues, that Foreign Fighters are specific kind of migrants who travel both short-term and long-term into a conflict area of their choice. Some do come back to their countries of departure. The thesis has two goals. First one is to find out if there is potential for securitization of Foreign Fighters in the Czech Republic present in Czech society. For this purpose, securitization theory is used. Second goal of the thesis is to look closer on the Foreign Fighter phenomenon both in general and in local circumstances. The thesis presents analysis of academic literature on the topic of Foreign Fighters. It discusses definitions, Foreign Fighter numbers and threat assessment, and approaches adopted to deal with the phenomenon. Next, specifics of foreign Fighters in the Czech Republic are discussed. A survey was launched in order to gain data for this study among Czech society. Results of the survey indicate there is not much interest for securitization of the topic in the Czech Republic. Further results yielded there is not much of a difference in Czech Foreign Fighters and their compatriots from other countries, except maybe focus of Czech fighters on Ukraine except Middle East.
Demographic transition, population growth, demographic ageing - interrelations and development contexts at the regional level
Avram, Cristina ; Kučera, Tomáš (advisor) ; Bleha, Branislav (referee) ; Fiala, Tomáš (referee)
Demographic transition, population growth, demographic ageing - interrelations and development contexts at the regional level Abstract This thesis aims to examine how the timing and pace of the demographic transition correlated with the timing and pace of ageing at the regional level in Czechia and also to contribute to understanding the determinants and evolution of demographic transition, specifically mortality and fertility decline, and connect it with the population ageing. It is a common belief that ageing is the result of demographic transition, but there is a limited number of studies that investigate the interrelations between these two processes. The greatest challenge was the difficulty in comparing historical and current data caused by changes in the administrative division during 1868-2017. Thus, the recalculation of data was needed to analyse trends in mortality and fertility. 2011 statistical units at the level of districts were chosen as basic units for analysis. The data recalculation was preceded by the reconstruction of historical districts maps and population data estimation for intercensal periods. Data were recalculated using spatial overlays in GIS software and database processing operations both for population and vital statistics. This step was followed by the data analysis....
