Application of the Moral Foundations Theory on Czech Environmental Discourse
Rysková, Lenka ; Smetana, Michal (advisor) ; Franěk, Jakub (referee)
The bachelor thesis focuses on moral argumentation related to environmental issues within Czech discourse. The aim of the thesis is to find out what moral foundations is the environmental discourse in the Czech environment based on, which is achieved by applying the Moral Foundations Theory to this discourse. The theoretical part of the thesis maps the Moral Foundations Theory itself and the existing knowledge from its application to political science and environmental issues. In the practical part, the theory is applied to two separate parts of environmental discourse - op-eds published on internet news portals and speeches delivered in the Chamber of Deputies of the Parliament of the Czech Republic. A qualitative content analysis is used to establish an image of the representation of each moral foundation within these two parts of the research. The combination of the results from these parts is then used to answer the research question.

Photodynamic antimikrobial therapy
Ryšková, Lenka ; Buchta, Vladimír (advisor) ; Boštíková, Vanda (referee) ; Jílek, Petr (referee)
Photodynamic antimicrobial therapy Background: Photodynamic antimicrobial therapy is proposed as a potential topical, noninvasive approach suitable for treatment of locally occuring infection. The fact that bacteria are becoming increasingly resistant to antibiotics and antiseptics has lead to an increased interest in the field of developing new alternative eradication methods, such as PACT. Whereas gram-positive bacteria are generally sensitive to photoinactivation, gram-negative bacteria and fungi are usually less susceptible. Research of photosensitizers (PS) as well as development has been going on with the aim to find effective antimicrobial substances, which would have a broad-spectrum potency. The aim of this paper is to evaluate the antibacterial and antifungal effect of fifteen Pc derivatives. Methods: Fifteen different Pc were investigated. Their photokilling activity was tested on Staphylococcus aureus, Escherichia coli and Candida albicans. After treating of microbial cells with Pc in the concentrations: 1 mg/l, 2 mg/l, 4 mg/l, 8 mg/l for 30 minutes, the cultures were irradiated with low-power laser light wavelength of 670 nm (20 J/cm2 , 40 J/cm2 ). The effectiveness of photoinactivation was evaluated based on the decrease of a number (log10) of viable bacteria. Results: Eight tested Pc...
