Caetano Veloso and the Brazilian tropicalist movement
Tichý, Milan ; Housková, Anna (advisor) ; Dufková, Vlasta (referee)
The thesis Caetano Veloso and Brazilian tropicalism analyses the music movement of the same name, which took place in Brazil between 1967 and 1968. It traces its context and mutual synergies with avantgarde art, which originated at the same time in the innovatory art of ????, in the radical theatre Oficina, in the new wave of brazilian cinema represented by Glauber Rocha or in the work of a group of concrete poets led by the Campos brothers; all of this with regard to the landmark political development of the end of the decade. The thesis also deals with the connections and similarities of the movement with the aesthetic and philosophical positions of Brazilian modernists and it traces the significance of tropicalism for the further orientation of Brazilian songwriting. This analysis is preceded by a summary of the overall development of Brazilian music, mapping not only its roots but also all of the key moments, impulses, trends and mutual connections. The emphasis is put on the art of songwriting, which is dominant in Brazil.

Diagnostics of low-temperature plasma using the Langmuir and emissive probes
Klusoň, Jan ; Kudrna, Pavel (advisor) ; Tichý, Milan (referee)
Magnetron sputtering belongs to the most important methods of production of thin films with a wide range of physical properties. Examples include hard, wear-resistant coatings, low friction ones, corrosion resistant ones as well as coatings with specific electrical or optical properties. During the development the basic sputtering process has been significantly improved and nowadays there are a number of various techniques of magnetron sputtering. Pulsed magnetron sputtering presents one of these techniques. The pulsed regime is especially suitable for the deposition of insulating layers because there occurs no effect of charging up of the target followed by arc events. The fact that pulsed sputtering allows reducing the substrate temperature during the deposition is also important. This thesis deals with the low-temperature plasma in magnetron discharge generated by pulsed DC voltage. The measurement was carried out in the experimental apparatus of the cylindrical magnetron. The plasma diagnostics was performed by means of the electrostatic Langmuir and emissive probe. The dependencies of the basic plasma parameters, i.e. electron density, electron temperature and plasma potential, were evaluated with time and spatial resolution. The dependencies on pressure, length of the voltage pulse and the value of...

Radicals formation in supersonic plasma jet
Mašát, Milan ; Tichý, Milan (advisor) ; Glosík, Juraj (referee)
Title: Creation of radicals in electric discharge supersonic plasma jet Author: Milan MaSat Department: Department of Surface and Plasma Science Supervisor: Prof. RNDr. Milan Tichy, DrSc. Supervisor's e-mail address: Milan.Tichy@mff.cuni.cz Abstract: Free radicals are the key intermediates and propagators of chemical reactions in Earth's atmosphere. Study of their structure and chemical properties is vital for understanding the processes in atmosphere. But their high reactivity brings the need for specific research methods. In-situ preparation and non-invasive detection and characterization techniques are needed. Most commonly used laboratory techniques such as photodissociation or electric discharge generate radicals at temperatures that are significantly higher then those under atmospheric conditions, which we intendto model. In this work, I was developing a source of cold radicals and experimental techniques for measuring their properties. 1 combined plasma source, which creates sufficient concentrations of radicals with supersonic expansion in which the translational and internal degrees of freedom are cooled deeply below the room temperature. For their characterization I used high-resolution spectroscopy utilizing near infrared laser diodes. I also developed and built electronic circuits and software...
