Testing of binders of thermal insulations for specific applications on technical appliances
Maňák, Jan ; Kulísek, Karel (referee) ; Petránek, Vít (advisor)
This work focus on testing alcali-activated binders for thermal insulation which could be used for special industry devices. In the beginning of this work is presented example of thermal energy storage where these specific alcali-activated materials can be used. Ensuingly two construction with thermal energy storage tanks are mentioned. Most of the interest aims on ageing and rheological properties of alcali-activated binder. Some rheological methods are also discussed. In the end of this work is added practical experience.

Lubricants created by nature
Drobilič, Ivo ; Urban, Filip (referee) ; Nečas, David (advisor)
This bachelor thesis provides an overview of substances which can be considered as the lubricants in its natural environment. The first part of the thesis of focused on lubricants in human body. The substances such as water, blood or synovial fluid are analysed in a detail. The following chapter deals with lubricants in everyday life. As the example, decrease of tyre adhesion in case of rain or longer breaking distance of trains as a consequence of presence of leafs on rails, can be mentioned. The last part, in addition, summarizes the lubricants which are based on natural products.

Reduction of Valvetrain Mechanical Losses
Kučera, Pavel ; Píštěk, Václav (referee) ; Novotný, Pavel (advisor)
The topic of this thesis is the mechanical losses in the valvetrain. The purpose is to describe the creation of individual losses and their possible reduction. The main factor of creation of losses is friction. The result of this thesis is to highlight the possible methods to reduce friction and other influences acting on the valvetrain. The main benefit is description various types of surface and design modifications of valvetrains, which are already used or are in development.
