Sadílek, Jiří ; Jančář, Josef (referee) ; Kohout,, Jan (referee) ; Hell,, Jaroslav (referee) ; Kučera, Jaroslav (advisor)
The aim of this work is to study the effect of thermal history to structure and properties not only of oriented polypropylene monofilaments with different orientation but of course of isotropic non-oriented polypropylene. Term thermal history includes thermal regimes from alpha relaxation temperature (T?) to melting temperature (Tm). This work consists of three parts. The changes of dynamic mechanical properties, strength, deformation and tensile modulus of polypropylene samples according to annealing temperature (Ta) are described in the first part of this work. In the second part, the changes of crystal phase are observed. Preferentially, calorimetric behaviour (DSC), changes of crystal dimensions and orientation function of crystal phase (X-ray) are observed. Measured values from the first and the second part of this work were used for calculation of total orientation function of PP samples. Rheological measurements are shown in the third part of this thesis. Rheological measurements consist of short isothermal creep, shrinkage of free tapes and static deformation at higher temperatures. Measured rheological values were performed using rheological models. Using these models characteristics of entropic spring, instantaneous elasticity and viscosity and tendency to get to state of ease were calculated.

Connectivity / Democratic City_Radnice pro Staré Brno
Macanová, Tereza ; Vymětal, Bedřich (referee) ; Palaščak, Michal (advisor)
The Bachelor thesis deals with the design of a standalone city hall building for Staré Brno on Mendel Square. The work takes into account the reconstruction of the square according to the winning urban design proposal. The design addresses the continuity of the building and visual connection with the surroundings, which influences the shape of the building. The design of the square and the city hall building gives great emphasis on greenery, which is neglected in the current state. Connectivity, as the main theme, creates the resulting appearance of the building. The goal of this work is to connect city hall using greenery. There is an intermingling of multiple functions, mainly civil amenities, city hall administration, and housing.

The theme landscape orientation on the primary school using fieldwork
Rechnerová, Maria ; Dvořáková, Michaela (advisor) ; Zicha, Zbyněk (referee)
This diploma thesis deals with the ability of children of younger school age to orient themselves in the landscape. Its goal is to create specific proposals for working with children of younger school age, which systematically develop the children's necessary skills based on researched starting points. Therefore, the work first focuses on the theoretical starting points of geography didactics. These are then followed by topics for activities with children. Here is a summary of the way of working, which we have conceived as suitable for the development of orientation and map skills. We also focus on spatial orientation within the valid Czech curriculum and analysis of textbooks that are used for teaching national history topics in the 1st grade of primary schools. The following is a summary of the psychological starting points for teaching orientation to children of younger school age, because this period is specific in the perception of the surrounding world and it is important to appropriately follow up on these specifics. On the basis of theoretical starting points, specific topics are created for working with children, especially at the age of children in the 3rd - 5th grade of elementary school. Here we deal with the natural and gradual development of map skills, which are necessary for...

The perception of objective and subjective risk of alpine tourism users.
Opršalová, Veronika ; Brtník, Tomáš (advisor) ; Bačáková, Radka (referee)
Author: Veronika Opršalová Title: The perception of objective and subjective risk of alpine tourism users Objective: Characterization of mountaineering and examination of awareness of the differences between subjective and objective danger. Methods: A questionnaire survey was used to obtain data from respondents, so it is quantitative research. Results: Of the total number of respondents, 86.3% stated that they could distinguish between subjective and objective dangers, which was verified using the following questions. Furthermore, it was found that the participants of mountaineering are aware of their mistakes and try not to repeat them. 61.3% of respondents have become more careful over the years, 30% of respondents have not changed their view of danger over the years and the remaining 8.7% of respondents no longer perceive danger as much as they used to after years. Conclusion: The thesis characterizes mountaineering and deals with its history. It also deals with the perception of subjective and objective danger of the participants of mountaineering. The thesis summarizes information on necessary equipment for mountaineering and trip planning. Keywords: climbing path, climbing, orientation, planning, equipment

Magnetic orientation in mammals
Tejmlová, Kristýna ; Němec, Pavel (advisor) ; Vácha, Martin (referee)
Earth's magnetic field can provide animal with both directional and positional information. The ability to perceive and utilize information extracted from the geomagnetic field is called magnetoreception. Magnetoreception mechanisms remain largely unknown. Three main hypotheses are currently supported by experimental evidence. The light-independent mechanisms are based either on electromagnetic induction or on biogenic magnetite. The light-dependent mechanism is based on specific chemical reaction between radical pairs. Perception of the geomagnetic field facilitates both long- and short-distance orientation of animals. Some animals exhibit the magnetic alignment, i.e., spontaneuos preference for a certain geomagnetic direction. Another manifestation of magnetoreception is magnetic compass (polarity- or inclination-based, depending on species), which enable an animal to determine the azimuth, i.e., the angle between the direction of motion and geomagnetic field vector. Magnetic map sense enable an animal to determine its position and direction to the goal destination, most likely utilizing the inclination and the intensity of the geomagnetic field as navigational cues. Magnetic orientation of mammals seems to be a widespread phenomenon. Light- independend, polarity compass has been reported in...
