Impact of uncoventional technologies of soil cultivation on soil quality
Suchá, Kateřina ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
Agricultural land is being handled by various tillage of soil which affects properties of soil. There are two types of tillage treatment. These are conventional (classic) tillage with plowing and minimization tillage (plowing is excluded). The aim of this particular work is to assess the quality of the soil near the village of Bohaté Málkovice, which is being (long-term) handled by minimization tillage. As indicators of soil quality, we used selected physical and physico-chemical characteristics, which are determined from analysis of disturbed and undisturbed soil samples from the top soil layer (0-10 cm) by standard methods in laboratory conditions. The theoretical part describes the basic physical properties of the soil and the ways of their determination. The practical part is devoted to the presentation of the examined locality and the results of selected physical and physico-chemical properties of the soil are presented and subsequently evaluated. In the conclusion, the impact of used tillage in Bohaté Málkovice on the selected soil properties is assessed.

Changes in physical properties of the subsurface soil layers depending on the technology tillage
Bažantová, Adéla ; Larišová, Lucie (referee) ; Kameníčková, Ivana (advisor)
For the correct course of soil processes, plant growth and development is necessary the tillage of soil. Usually we choose between two technologies, that those adjustments are cariied out by. Both are conventional tillage, which uses plowing and minimization tillage, wherein is excluded plowing. Objective of this work is to determine the impact of these tillage treatments on selected physical properties of soil, i. e reduced bulk density of the soil, porosity, momentary contents of water and air in the soil. Soil samples were collected by Kopecky rollers (V = 100 cm3) taken from depths of 0,1; 0,2 and 0,3 m that were used to evaluate. Two samples were collected each July. This period is referred as a critical due to higher soil compaction (movement of mechanization, root system of plants and rainfall totals). Experimental research was conducted in years 2008 – 2011 in the village Bohaté Málkovice.

Vývoj čalounické technologie od historie po 30. léta 20. století
Falátek, Adam
This thesis deals with the historical development of conventional technologies in upholstery. Its aim was to analyze the procedures of upholstery in different historical periods, to notify important milestones and factors that influenced the classical technology. The result was a summary of the issues within conventional technology of upholstery.

Studie čalounění křesel v meziválečné době, doporučení pro rekonstrukce
Kalousová, Adéla
Diploma thesis follows up the classical technologies of upholstered seats from the interwar period. It is particularly focused on the composition of the individual layers of upholstery and feasibility of the construction nowadays. The theoretical part includes description of the interwar period and selected designers and manufacturers of that time. It also describes construction of different types of upholstery and materials used for the construction. The ergonomics of seating and impacts of seating on the human health is mentioned. The practical part comprises of the reconstruction of an upholstered chair from the interwar period. The upholstery was made from contemporary materials, however keeping the classic upholstery technology.

Možnosti racionalizace systému kultivace půdy v zemědělském podniku
Habán, Josef
The thesis is focused on a particular farm and tillage system. First, the work discussed findings from literature sources to cultivate the land and their various systems. The following is part of the characteristics of the farm, its production and natural conditions a brief history. It described the historical and current agricultural technology and are designed to rationalize its options with regard to the improvement of the soil and the possibility of increasing the yield of major crops. At the end are evaluated the pros and cons of different tillage systems and explain the reasons for these conclusions with regard to future career opportunities.
