Analysis of the rheological properties of vegetable oils and their components
Divílek, Petr ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
This Master’s thesis is dealing with theoretical analysis of vegetable, mineral oils and synthetic fluids, and with measuring of density and viscosity of selected samples of electric insulating fluids. The main part of the thesis is focused on vegetable oils and their elements called fatty acids. Those are more detail described in separate capitols. In those capitols is described their utilization in engineering practice with focus on energetics, where vegetable oils are used in larger scale. In experimental part of the work is measurement of density and dynamic viscosity. Viscosity was measured on two different machines, first the Hoppler viscometer and on vibrating viscometer. Results of these measurement are evaluated in tables and graphs.

Evaluation microclimate in dairy farming in chosen enterprise and proposal for improvement.
VACUŠKA, Josef
The substance of this bachelor work is mainly to evaluate microclimate in dairy farming and to suggest ways for it{\crq}s improvement. Dairy farm is located in chosen enterprise. The work describes characteristics of temperature, moisture, wind{\crq}s speed in chosen stable and it{\crq}s impact on animals. Next step was to propose the ways which could that microclimate adjust on values, in which animals are felling well.
