Formation of nucleobases from formamide initiated by high-power density energy events
Michalčíková, Regina ; Civiš, Svatopluk (advisor) ; Šponerová, Judit E. (referee)
This Master's thesis deals with determination of nucleobases in formamide samples (pure or catalyzed form) after their initiation by high-power density energy events. The theoretical part states the reader to the problems of prebiotic chemistry and acquaints him with the various theories of the origin of the nucleobases. The experimental part deals with the analysis of the samples initiated by Laser System PALS, which was used for the simulation high-power density energy events. For the identification and determination of the final products of laser plasma initiated chemical reactions in the gaseous phase of the samples was used the Fourier Transform Infrared Spectroscopy. The liquid part of the samples and the nucleobases in this part were analyzed by the gas chromatography with the mass detection.

Learning motivation of the second generation of Vietnam immigrants
VOKROJOVÁ, Nela
This undergraduate thesis summarizes the basic motivation theory and knowledge that is available about the Vietnamese culture. The empirical section of this thesis is attempting to apply the revised translation of the PALS method. The results show that the reliability of the scales has most likely increased. At the same time, it is clear that some scales are still not functioning properly and therefore, it would be appropriate to think about how to edit them to create a more functional measuring tool for our environment.
Development of the Czech form of the Patterns of Adaptive Learning Scales (PALS)
KOVÁČOVÁ, Klára
The undergraduate thesis explores validity of genuine Czech translation of PALS questionnaire in Czech environment. This method is built on Carol Dweck?s goal theory, which is described in theoretical part, also with basic background in the field of educational motivation. Research was conducted on the sample of 549 pupils in 8th and 9th grade and their results were compared with original research of Carol Midgley et al. (2000). Factor analysis and reliability analysis was done on used scales and it is obvious that simplification and language modification of items is needed, but still it appears from the results that this method distinguish goals correctly in Czech environment and it can be put into practice after further research.
Proposal of ultra-high-power beams at the kilojoule iodine laser PALS
Novák, Ondřej ; Divoký, M. ; Böhm, P. ; Smrž, M. ; Turčičová, Hana ; Straka, Petr
The iodine kJ laser PALS is widely used by users. To extend the scope of the experiments, a proposal of new ultra-high-power (UHP) beams was done in detail. The model of the design is based on routine parameters of the laser PALS and on state-of-the-art of the ultra-high-power beams generation. Using the OPCPA technique, we propose two new alternative UHP beams at PALS with powers of 100 TW and 1 PW, respectively, including a pulse compressor and new front-end amplifiers. The amplification chain was simulated using coupled wave equations for optical parametric amplification. Layout of the two new beams in the existing PALS laser hall was also proposed.
Nelinearní procesy v koróně laserového plasmatu
Jungwirth, Karel
Results of the systematic studies at PALS of ion acceleration, electron trapping, virtual cathode formation, laser beam selffocusing and dense plasma jets production were presented via the invited lecture.
Hybrid laser chain SOFIA at the Institute of Physics AS CR
Turčičová, Hana ; Straka, Petr ; Skála, Jiří ; Králiková, Božena ; Rohlena, Karel ; Ullschmied, Jiří ; Jungwirth, Karel
SOFIA is a hybrid laser chain where the laser beam generated in a solid state oscillator is amplified in a gas medium of iodine photodissociation amplifiers.SOFIA project is realized to speed up the modernization of the laser system PALS by the OPCPA method.
