Varga, Martin ; Prokeš, Jan (advisor) ; Valentová, Helena (referee)
Our aim in the present work is to provide and evaluate AC and DC characteristics of the polyaniline based materials. Different experiemtal techniques and devices have been used to achieve this goal. An introduction to the theoretical concepts of conductivity is given as well. The core of this thesis is an investigation of temperature and low pressure dependences, as well as the ageing effects for two systems (composites) in respect of the different preparation conditions such as dopants and their molar concentration, origin and the content of inorganic component and the way of polymerisation. An agreement with theoretical models is discussed.

Valentová, Helena ; Pazdera, Jindřich (advisor) ; Pazdera, Jindřich (advisor) ; Hůla, Pavel (referee) ; Kotmel, Bohumil (referee)
This thesis deals one of the great figures in Romantic music in the 19th century César Franck, as a composer, organist and music teacher, too. To the significant part belongs Franck´s chamber music which I apply myself to in detail. That is particulary piano trio in F sharp minor, piano trio in B sharp minor, piano quitent in F minor, string quartet in d minor and certainly sonata for violin and piano A major. I mention also the only symphony of Franck in D minor considering numerous common features with his chamber music. We can find here also composerś youth when he was a child prodigy, his friendship with-known personalities ( as F.Liszt) and last but not least his mature period, when he composed his main work. I have to bring out that his works were some of the finest organ pieces to come from France in over a century, and laid the groundwork for the French symphonic organ style. We also get to know that as an organist he was particulary noted for his skill in improvisation, and is considered by many the greatest composer of organ music after J.S.Bachś successor
