Rojková Kovačíková, Zuzana ; Boonjob, Warunya (advisor) ; Chocholouš, Petr (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Analytical Chemistry Candidate: Zuzana Rojková-Kovačíková Supervisor: Warunya Boonjob, Ph.D Consultant: Doc. PharmDr. Hana Sklenářová, Ph.D. Title of diploma thesis: Dispersive liquid-phase microextraction of propofol using Dual valve SIA system with fluorimetric detection This thesis deals with determination of propofol using automated dispersive liquid - liquid microextraction (DLLME) in SIA system with fluorimetric detection. Amyl acetate was selected as the extraction solvent; acetonitrile was used as the disperser solvent. Measurement parameters in SIA system were optimized. The calibration curve was linear in the range of propofol concentration 8 - 64 µg/ml with the correlation coefficient 0.9945. The limit of detection (LOD = 0.83 µg/ml) and the limit of quantification (LOQ = 7.25 µg/ml) were calculated. Repeatability for concentrations 16 and 64 µg/ml was proved; the values of the relative standard deviations (RSDs) were 1.54% and 1.52%. The analysis time was 152 s in case of one sample injection.

Balance of identity and balance of power: The case of conflict dynamics between Saudi Arabia and Iran
Kováčiková, Zuzana ; Aslan, Emil (advisor) ; Kučera, Tomáš (referee)
This thesis applies the concept of religious (national) identity to the cases of Saudi Arabia, Iran and their proxy allies - state and non-state actors - in Lebanon, Syria and Yemen. The aim was to show that in the Middle East, Sunni and Shiite affiliations matter in the relationship between the regional powers and respective proxies, as opposing to realist statement that alliances, conflicts and political developments are only governed by pragmatic power interests. Additionally, the work examines whether religious national identities have impact on the dynamics of proxy conflicts. Overall, the objective was to establish comprehensive image of how ideational/constructivist and pragmatic/realist factors work in combination to influence alliances, enmities and conflicts in the Middle East. Using qualitative methods of research, religious (national) identities of Saudi Arabia, Iran and their allies in Lebanon, Syria and Yemen were constructed so as to create ideational and realist points of departure, and then interlinked to show how convergence of religious identities helps in creating durable alliances if used in targeted manner as a strategic tool which can help safeguard national interests. The work shows notable differences in the use of this tool between Saudi Arabia and Iran, suggesting that it...

Wahhabi/Salafi Rhetoric in the Northern Part of the Caucasus Region
Kováčiková, Zuzana ; Ťupek, Pavel (advisor) ; Beránek, Ondřej (referee)
Salafism is considered a powerful mobilising ideology used by many Islamist and terrorist movements worldwide. This ideology was also adopted by the Caucasus Emirate, a once influential terrorist organisation that used to operate in the mountains of Russian Northern Caucasus. This paper thoroughly analyses religious ideas and trends behind North-Caucasian Salafism, as the body of academic sources concerning this issue is quite limited up to now. The analysis deals with main topics and narratives of the Caucasus Emirate Salafist propaganda, but also considers religious authorities that grant theological legitimacy to these ideological concepts. Both Arab and North-Caucasian spiritual leaders and ideologues are under scrutiny of this analysis. Concluding part of this paper outlines shifts in the rhetoric, which are caused by the conflict between the Caucasus Emirate and the so-called Islamic State of Iraq and Levant. Analysis of the rhetoric draws conclusions using previously published academic work as well as the authentic internet sources, i.e. jihadist websites and videos in the Russian language. The paper suggests that the rhetoric of North-Caucasian Salafists is generally similar to the rhetoric of any other jihadist movement, but at the same time it contains number of inconsistencies as it...
