Working hours, their duration and work schedule Abstract The diploma thesis deals with the topic of working hours and related institutes in Czech labor law in order to provide a comprehensive overview of the valid legal regulation. In addition, the work deals with the issues of breaks and rest periods, which are inseparably related to working hours. The thesis is divided into six chapters, which are subdivided into subchapters. The first chapter contains a historical excursion into the history of working hours regulation in the Czech lands from the Middle Ages to the present. I also mention the valid legal regulation of working hours at international and national level. The second chapter defines the concept of working hours, followed by a detailed description of each of the related institutes - its length, scheduling of work, work overtime, night work, on-call duty and working hours register. The following chapters discuss the organization of working hours for employees who look after children or other natural persons, pedagogical workers, workers in transportation and employees working under agreements to work outside the scope of employment. For these employees, there are some deviations from the general legal regulation of working hours or special conditions, as I refer here. The last chapter deals with...

The aim of the study was to determine the effect on the growth of the cultures after the second growing year (coverage) and exposure of clearcuts, seed time and type of used planting material.Totally was measured on four areas - high fence (60x70 m), chopped (25x70 m), underplanting and the large calamity clearcuts. There were represented four different provenance and they were with or without modification of the root system, which were planted in six different dates (spring - autumn). Monitoring and evaluation were especially following features: losses, length of aboveground, increase of the terminal, root collar thickness, length and number of branches, length of needles, color of assimilation system, damage by biotic and abiotic factors. The results of my thesis confirmed that it is best to Douglas fir planted on small regenerative elements with adequate cover of surrounding vegetation. These areas register lower losses and higher increment of above-ground parts. The best planting date is in early spring. It also has confirmed great variability in the requirements for each provenance and Douglas sensitivity to drought. Effect of modification of the root system appears to be minimal.

The aim of this diploma thesis was to determine what influence has a different size (cover) of clearing on growing cultures after the third growing season, time of planting and a type of planting material. The reaserch was realized on clearings with dimensions 55 x 70 m, 25 x 70 m, in Podsadba and on a big Kalamitná clearing (4,4 ha). There were used four provenances with or without an adjustment of root system. 10 parameters and signs were measured and recorded on each individual tree. Observed values were statistically evalueted and written comment was added. The results of reaserch confirmed that minor restoration elements are more suitable for culturing Douglas Fir as they provide a favourable microclimate. In these areas are lower losses and plants show a greater increase in aboveground part. In terms of time of planting, the most suitable appeared in the early spring planting dates. The adjustment of root system before planting had a negative effect because treated seedlings had lower gain and the losses were on average higher.

The goal of this thesis is to analyze the current state of vehicle brakes construction, possibilities of measuring the brake power, braking deceleration and to analyze the influence of pipe diameter to the beginning braking force, based on data from the measuring in the dynamic cylindrical testing lab. In the first part are described braking systems and Czech and International legislation, which have to comply with all road vehicles. The section also describes ABS, the modern brake system elements and testing methods that measure the requirements of the braking effect. The next section discusses the methodology of measuring and describes the experimental cylindrical test at Czech Agricultural University in Prague. In this thesis, they are processed and evaluated the data obtained from the measurement. At the conclusion are summarized the findings from the data evaluation and overall assessment of the influence of pipe diameter to beginning braking power.
