The History of motors sports in South Bohemia \\
DRAHOŠ, Jiří
Bachular thesis deals with history and progress of motosport in the South Bohemian Region, where the motosport was very popular. Bachular thesis is focused on motosports, particularly motocross. From the point of view of ground plan is the topic of this bachular thesis divided into the districts České Budějovice, Písek, Tábor, Jindřichův Hradec, Český Krumlov, Prachatice, Strakonice and earlier also involved Pelhřimov, which was in November 12, 2000 removed to Vysočina Region.

Parameters Affecting Process of Particles Sedimentation: III
Kulaviak, Lukáš ; Růžička, Marek ; Drahoš, Jiří ; Hladil, Jindřich
The aim of our contribution is to study the effect of the particles properties on their settling behaviour in solid-liquid suspensions. Generally, the particles interact mutually in a complex way. They are also coupled with the motion of the liquid whose flow they generate. The resulting behaviour depends on many mechanical particle properties (roughness, shape, size, abrasive hardness, texture, fine particle presence) and electrochemical properties of the interface between the particles and water (surface tension, zeta-potential, electrostatic potential, etc.).

Research of Multiphase Systems at ICPF AS CR Prague
Zedníková, Mária ; Růžička, Marek ; Drahoš, Jiří
The aim of this contribution is to present to the Czech waste water treatment community the multiphase flow research at the ICPF ASCR. The goal of the research is to understand the basic physical mechanisms of flow systems with two or more phases. The interest covers a broad range of the multiphase flow systems; for instance: production and hydrodynamics of bubbly mixtures, flow regimes and their identification, effect of control parameters on the flow regimes, mass transfer in gas-liquid systems, bubble formation, coalescence and break-up, hydrodynamic interactions of bubbles, interaction of bubbles with solid particles, sedimentation of polydisperse mixtures etc.
