The limits of movement and quantification of bedload amount for gravel-bed rivers
Roušar, Ladislav ; Matoušek, Václav (referee) ; Tůma, Antonín (referee) ; Veselý, Jaroslav (advisor)
Doctoral thesis in detail and comprehensively deals with mechanic of incipient bedload motion for gravel-bed rivers. This study based on theoretical knowledge, experimental researches, numerical models and field survey extends present knowledge concerning with incipient bedload motion and sediment transport at small relative height and hydraulically rough surface bed for turbulent unaerated free surface flow. Incipient bedload motion and sediment transport have been determined for homogeneous and inhomogeneous bed materials. For homogeneous bed material the velocity profiles have been described by different methods in near the bed. Further, hydraulic flow resistance has been evaluated. In the case of inhomogeneous bed material, static armouring and influence of surface layer sorting on hydraulic roughness have been investigated. The correctness of obtained knowledge has been confirmed on the object of nature-inspired river widening. Results shown, among others, that incipient bedload motion does not depend on relative height or final armouring of surface layer to what extend hydraulic roughness is influenced.

Subsidy fraud and damaging the financial interests of the European union (Section 260 of the Penal Code)
Roušar, Ladislav ; Heranová, Simona (advisor) ; Mulák, Jiří (referee)
Subsidy fraud and damaging the financial interests of the European union (Section 260 of the Penal Code) Abstract This thesis is focused on Czech and European legal framework of fight against subsidy fraud. The thesis also focuses on practices and general concepts of institutions which are tasked with fighting fraudulent conducts. The method of processing is mainly analysis and description. The thesis is structured in three parts. The first part brings attention to the characteristics of subsidy fraud as codified in section 212 of the Czech penal code. The chapter includes authors' suggestions of changes to the section 212. The second part presents analysis of crime of damaging the financial interests of the European union as codified in section 260 of the Czech penal code. The chapter includes authors' suggestions of changes to the section 260. After that international and European legal framework, which represents foundation of Czech legal framework, is thoroughly observed. The thesis explores the history of fight against fraud in the European union and its predecessors from the beginning to current days. Further attention is brought on European institutions tasked with fight against fraud, specifically European Public Prosecutor's Office and European Anti-Fraud Office. Possible weaknesses in the concept...
