Optimization of separation and quantification of prospective products of big bang
Smitka, Jaroslav ; Tesařová, Eva (advisor) ; Kalíková, Květa (referee)
The thesis is a contribution to research aimed at modeling the conditions of the Big Bang and monitoring possible reaction products. As the starting compounds were selected 2- amino-1-butanol, 3-methoxy-1-propanol, 2-methyl-1-butanol, formamide, some of which were subsequently bombarded by PALS at J. Heyrovsky Institute of Physics, Academy of Sciences. Gas chromatography hyphenated with mass spectrometry and liquid chromatography with UV detection were used for analysis. In GC-MS, calibration of 3- methoxy-1-propanol and 2-methyl-1-butanol was carried out and LOD and LOQ were calculated. Comparison of 3-methoxy-1-propanol and bombarded 3-methoxy-1-propanol did not show the emergence of new products since 3-methoxy-1-propanol was in excess. The found compounds can be more likely identified as impurities present in a solvent or in the individual standards. The optimized HPLC system has managed to separate the three standards. Formamide, which is unsuitable for analysis by gas chromatography, due to its high polarity, however, eluted in all tested systems with system peak (the dead time marker). Nevertheless, the bombarded sample was analyzed for comparison with the original standard. Comparison, however, showed no reaction products in the bombarded sample. Key words: big bang laser sparks formamide...

Theological Perspectives in Cosmology of Georges Lemaître
Rejman, Daniel ; Petráček, Tomáš (advisor) ; Šmíd, Marek (referee) ; Bouma, David (referee)
The thesis analyzes the thinking, legacy and the second life of the work of a prominent mathematician, cosmologist and the Catholic priest Georges Lemaître. The patterns of his thinking (expecting the intelligibility of the cosmos, assuming the hidden nature of God for research of natural science, seeing indeterminism in the evolution of the cosmos and separating the scientific and religious approach to reality) are presented on the basis of sources and literature based on Lemaître's texts and texts of scholars who dealt with his life and work. Everything is further complemented by the opinions of authors writing about the broader contexts of the history of cosmology and its interferencee with religion. Those long-term tendencies are drawn in more detail and further connected and compared with more general European ideas (the book of nature, the question of human free will, light as a backdrop of creation, appreciating the simplicity of hypotheses). Special emphasis is placed on the religious connotations of Lemaître's thinking - these are also presented with regard to the development of time, to which insights are further applied using modern models of the relationship between science and religion. It is the temporal transformation of that relationship within Lemaître's life path and the resulting...
