Vliv seřízení tříbodového závěsu traktoru na výstupní parametry orebních souprav
Kratochvíl, Ivo
The aim of the thesis "Influence of adjustment of three-point tractor hitch on output parameters of tractor sets" was to elaborate the current state of the tractor construction and to find out above all, the influence of adjustment of the three-point hitch of the tractor and setting of the working machine on output parameters of tractor sets. Part of the work was the experimental measurement of a total of three tractor sets with full mounted depth cultivator, full mounted plow and semi-mounted plow. For the first tractor set, the effect of thrust and pressure in the upper pull rod of three-point tractor hitch on the output parameters of the tractor set with depth cultivator was determined. For the second plow tractor set, the influence of the length of the upper pull rod of three-point tractor hitch on the parameters of the plow tractor set was determined. In the third plow tractor set with a semi-mounted plow equipped with a traction cylinder, the influence of the pressure in the traction cylinder on the output parameters of the plow tractor set was determined. From all three measurements, the results have been achieved that when the three-point tractor hitch is correctly adjusted, it reduces slippage, increases surface performance and decreases fuel consumption.

Výměnný nastavbový systém pro dopravu v rostlinné výrobě
Kratochvíl, Ivo
This thesis deals with swap body system in crop production and conditions for the operation of farm machinery on public roads. Another part of work focuses on the application and harvest lines in crop production. Swap body types and their comparison of technical parameters are described. The technical-economic parameters at tractor set with swap body system compared and tractor set with single-purpose semitrailer are compared. Tractor set with swap body system has despite the higher purchase price a lower total hourly operating costs due to its transportation options wider range of materials, which led to the greater use throughout the year.

Prehospital urgent care about patient with inspiration pursiness
KRATOCHVÍL, Ivo
ABSTRACT This Bachelor thesis deals with the providing of urgent care to inspiratory dyspnoea patients. It contains definition of the inspiratory dyspnoea, description of each state of the inspiratory dyspnoea, differentially diagnostic and therapeutic procedures. It presents latest findings from specialized literature on this topic. The theoretical part of the thesis mentions different diseases related to inspiratory dyspnoea states. Furthermore, the theoretical part includes therapeutic means and procedures that can be used for live-saving actions and within pre-hospital care for clients with inspiratory dyspnoea. The intention of this thesis was to point out differences between children and adult patients and differences between care for children and adults. Practical part of the thesis is focused on the degree of paramedics' orientation in the theory of pre-hospital urgent care in inspiratory dyspnoea and their theoretical knowledge and skills in treating these states. It is them who decide on life and death, which is a very serious fact particularly in case of children patients, but also adults. A quantitative research was conducted through a questionnaire. The goal was to map out the knowledge of differentially diagnostic procedures and subsequent appropriate therapy in employees of Emergency Medical Service of the Vysočina Region. Two hypotheses were drawn up to achieve the goal. The first hypothesis claimed that paramedics knew urgent care procedures and treatment for inspiratory dyspnoea patients at juvenile age. The second hypothesis said that paramedics did not have enough opportunities to practice securing air passages in children. The questionnaire survey has confirmed both hypotheses. The thesis should serve to improve theoretical preparedness of paramedics for providing urgent care to inspiratory dyspnoea clients and can be used as a study material on the topic.
