A short history of Lemken company follows. The second part of the thesis compares the disc and the skive stubble ploughs in conditions of the agricultural company Zas Dražice Plc. Following gauges were examined during the field tests: cloddishness in cultivated part of the soil, defray postharvest rests, gas consumption or investment and operating costs.

Comparison turntable and stubble plough in light of qualities effected stubble ploughed under and gas consumption.
 RŮŽIČKA, Jiří
This thesis concentrates in problematics of stubble ploughed under and comparission disk and skive stubble plough. First part contains the summary of theoretical knowledge of soil and its elaboration, as well as the knowledge of farm machinery and specific division of stubble ploughs by its working organs. Follows by the summary of the most used and sold stubble ploughs in Czech Republic within its detailed description.

Specification of the relationship between gas consumption in commercial and industrial sector and outside temperature
 Pálková, Eliška ; Stroukal, Dominik (advisor) ; Čermáková, Klára (referee)
Aim of this thesis is to make the relationship between the gas consumption in commercial and industrial sector and temperature more accurate. The thesis is based on broad data which describes gas consumption of companies from the whole distribution network in the Czech Republic and information about temperature in the areas where the distribution networks operates. For the estimation of the model is used the weighted least squares method. The results show decreasing trend in the consumption during summer by 61%, during weekend by 41% and during holidays by 28%. The consumption is the most sensitive to the changes in temperature in the range of -1 °C to 20 °C and when the temperature is below -7 °C or above 24 °C the consumption doesn't react to the changes in temperature anymore.
