Novel polymeric materials for electromembrane processes
Galajdová, Barbora ; Pientka, Zbyněk (advisor) ; Slepička, Petr (referee) ; Abbrent Nováková, Sabina (referee)
Present study describes synthesis, characterizations and electrochemical properties of novel materials or novel approaches of preparation and their testing for suitability in industrial application. Work is divided into two main groups. First group is focused on preparation and characterization of ion-exchange membranes and second group is focused on preparation and characterization of ionic liquids. Prepared ion-exchange membranes are further split in two subgroups: a) Anion exchange membrane - synthesis and characterization of chloromethylene polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene copolymer, which was tested in water alkaline electrolysis b) Cation exchange membrane - synthesis and characterization of: i. poly(vinyl phosphonic acid-co-acrylonitrile), which was tested in fuel cells ii. polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene with sulfomethyl group, which was tested for use in microbial electrolysis Prepared ionic liquids are also divided into three groups based on the main function group: a) Imidazolium - ethyl methyl imidazolium phosphonic acid ethyl ester b) Phosphonium - methyl tributyl phosphonium bis (trifluoromethyl sulfonyl) imide c) Sulfonium - trimethyl sulfonium bis (trifluoromethyl sulfonyl) imide Ionic liquids were synthesized and...

Manas Air Base and U.S.-Kyrgyz Relations
Nováková, Sabina ; Sehnálková, Jana (advisor) ; Horák, Slavomír (referee)
The following thesis is a case study of the U.S. Manas air base in Kyrgyzstan. It addresses the significance of the base in the context of mutual U.S.-Kyrgyz relations after 2001. It aims to analyze the bilateral negotiations between the U.S. and the Kyrgyz on establishing the air base, its functioning, and eventually its closure in 2014. Among the research questions, it seeks to explain the respective positions of both parties, the motives behind their actions, and factors that influenced this negotiation process. The analysis shows that the extensive U.S. efforts to get and maintain access to the facility were driven by the necessity to secure transportation corridors to and from Afghanistan. Kyrgyzstan, on the other hand, was primarily interested in financial benefits stemming from having an American base on its territory. The U.S. let local elites enrich themselves in connection with the air base revenues. Kyrgyzstan's internal instability also had a major impact on its stance towards foreign policy matters and the issue of the Manas air base in particular. The U.S. was a stronger player in this asymmetric relationship, but Washington often got into situations where it was being pulled by Kyrgyzstan's domestic developments, which effectively determined mutual relations. The analysis concludes that...

Central Asian Foreign Fighters in Syria
Nováková, Sabina ; Bureš, Oldřich (advisor) ; Záhora, Jakub (referee)
This thesis deals with the phenomenon of Central Asian foreign fighters in Syria, 2011- 2017. It analyzes their radicalization, recruitment, and travel patterns. Special emphasis is placed on tracking the home states' responses, including elements of de-radicalization and counter-radicalization. The thesis has found that there is arguably no single factor explaining the Central Asian fighters' radicalization; nor is there a typical profile of a Central Asian fighter. Available data suggest that radicalization and extremist recruitment most often occur in Russia. Furthermore, the analysis of travel patterns has shown that the majority of Central Asian fighters traveled to Syria either indirectly via multiple countries (again, most often Russia) or directly from their country of origin, and then crossed the border from Turkey. The thesis concludes that all five Central Asian states have adopted policies to address the perceived security threat of returning foreign fighters, whereas the hard, restrictive and punitive approach has been prevalent all across the region.
