Design of hydraulic circuit for lifting device
Tichý, Antonín ; Budík, Tomáš (referee) ; Merenus, Ondřej (advisor)
The aim of this Bachelor´s thesis is to purpose a hydraulic circuit as well as a construction of a hydraulic engine. In the first part, literature retrieval in field of hydraulic constructional components is presented. In the following practical part, the thesis presents the construction of the engine, based on corresponding calculations. On the basis of the designed hydraulic engine will be a schematic connection to the hydraulic circuit created. The thesis includes also a drawing documentation of a selected parts.

Comparison of machine tool structures from traditional and non-traditional materials
Tichý, Antonín ; Hermanský, Dominik (referee) ; Merenus, Ondřej (advisor)
The topic of this diploma thesis is compare materials in machine tool structures. The introduction part is about literature retrieval in field of constructional components in machine frames. There are discribe the indiviual parts of machine structures their properties and influence, witch affect their static toughness, stabilty and accuracy of the whole milling machine. The most important part is focused to the materials witch constructions of machine are made from. The main of this thesis is a practical part, where is designed the own model of milling machine solved on the basis of experiences gain. The important choose was appropriate topology and materials witch the machine frame was made.

Release of bisphenol A and its analogues from dental restorative materials
Tichý, Antonín ; Bradna, Pavel (advisor) ; Izakovičová Hollá, Lydie (referee) ; Suchánek, Jakub (referee)
Bisphenol A (BPA) is an endocrine disruptor that may be released from dental polymeric materials. The aim of this study was to examine the kinetics of the long-term release of BPA and its analogues from restorative materials (composites, hybrid glass ionomer cements) and polycarbonates used in dentistry. Extracts in ethanol and artificial saliva were collected after 1-260 days for restorative materials and after 1-84 days for polycarbonates. All extracts were analyzed by ultra high performance liquid chromatography-tandem mass spectrometry. BPA was detected in all tested materials, while its analogues were not found. The release of BPA from all tested materials was highest during the first day, followed by a significant decrease for all materials and a complete stop for the "BPA-free" composites. Among restorative materials, the highest amounts of BPA were released from composites with BPA-based monomers, followed by hybrid glass ionomer cements. The least BPA was released from "BPA-free" composites. Shorter irradiation time did not significantly affect the total amount of BPA released from restorative materials, but it significantly increased the release of BPA during the first day. The release of BPA from polycarbonates was significantly higher than from restorative materials. Given the current...

Bank account
Tichý, Antonín ; Liška, Petr (advisor) ; Hurychová, Klára (referee)
Bank account Abstract This diploma thesis deals with the valid legal regulation of the bank account according to the legislation of the Czech Republic. However, the legislation of the Czech Republic is greatly influenced by the legal acts of the European Union, which are binding for the Czech Republic because this obligation is given by the country's membership in this organization. Therefore, for a more comprehensive understanding of the issue of legal regulation of the bank account, certain sections of this thesis mention several relevant provisions of legal regulations issued by the European Union. The main aim of this diploma thesis is to analyse the legal regulation of the bank account contained predominantly in the Civil Code as well as in the Payment System Act. The introductory section of this thesis focuses on the bank account as such - its characteristics and nature, and gives a brief history of its development. Furthermore, this chapter defines the term deposit and analyses the issue of the ownership of funds in the account in connection with the Czech case law. The second segment deals with the legal sources of the bank account both in the context of the Czech legislation and the legislation of the European Union. The introduction of the second segment is followed by an analysis of the previous...
