The incidency of injury among men players in the highest floorball league during years 2014-2019
Honzová, Petra ; Urbářová, Eliška (advisor) ; Novák, Jakub (referee)
The topic of this diploma thesis is the description of injury rate at floorball in the men's highest competition within the years 2014-2019. The work consists of theoretical and practical part. The rules of floorball, the popularity, and unions (federations) of this sport in our country and abroad, the concept of the season and the characteristics of the player's movement, including muscle imbalances are described in the theoretical part. A general division of sports injuries and a description of the most common injuries at floorball is a part of theory, as well as their prevention, registration, and treatment. In addition to contact with another person, glasses, shoes, the surface, the age of the player and, in the case of goalkeepers, knee protectors can influence injuries at this indoor sport. Further the method of educating coaches in the Czech Republic and the content of a seminar on compensation, which is presented to coaches at trainings, is also described there. The practical part is focused on the collection of injury rate data from paper and electronic records from matches in the seasons from 2014/2015 to 2018/2019. These results are compared with respect to the presence of a physiotherapist, the player's age, the surface in the halls, the phase of the season and the occurrence of an...

The tetrathiofulvalene derivatives: Their synthesis and properties
Nejedlý, Jindřich ; Starý, Ivo (advisor) ; Hocek, Michal (referee)
The goal of the diploma thesis was to prepare a spectrum of electron-rich macrocyclic derivatives of tetrathiafulvalene (TTF), which should serve as electron donors in interactions with electron-deficient acceptor molecules. A two-step synthesis was used for their preparation. First, a non-cyclic three-segment precursor was prepared by a reaction of a thiolate TTF construction block with a bis(bromomethyl)aromate. Then, a reaction of this precursor with another molecule of bis(bromomethyl)derivative closed the macrocycle. The latter reaction produced mainly [2+2] macrocycles containing two TTF and two aromatic units. In most cases, larger [4+4] macrocycles were also isolated from the reaction mixture. Besides thiolate TTF unit two other thiolate units, one with extended TTF core and other with smaller trithiafulvene ring, were used analogically in synthesis. By a combination of three thiolate blocks and five bis(bromomethyl)aromates 11 three-segment components were prepared and these were converted to 11 structural types of macrocycles with [2+2] and 7 macrocycles with [4+4] stoichiometry. The resulting macrocycles were characterized by 1 H a 13 C NMR spectroscopy and analyzed by a gel permeation chromatography. Their structures were also confirmed by high-resolution mass spectroscopy.
