The effect of paraglider`s wear and tear of different performance levels on the flight quality
Bartoš, Libor ; Dvorský, Jaroslav (advisor) ; Fiala, Miloš (referee)
Title: The effect of paraglider's wear and tear of different performance levels on the flight quality Aims: The main aim of this thesis is to define all main aspects participating in paraglider's wear and tear and changes of flight quality connected with it. Confirmation or non-confirmation of our assumption that paragliders of lower performance levels are wearing and tearing faster than paragliders of higher performance levels, especially because of poor handling by inexperienced pilots is also an important aim of this thesis. Methods: A porosimeter JDC MK1 was used as the main diagnostic tool. We have measured a porosity of skytex, material from which the paragliders are sewn. The total number of paragliders has been 253. Results were presented by using Excel spreadsheet and analyzed by using Pearson correlation coefficient. Results: Paraglider's unequal wear and tear of different performance levels was found. There has been a downward trend in wear and tear on the age of gliders from the category EN B to EN D. Performance category EN A has not been wear and tear on the level that we have expected. Keywords: paragliding, paraglider, skytex, flight quality, porosity
Financing of construction investment from the aspect of investor
Bartoš, Lukáš ; Klempt, Petr (referee) ; Kocourková, Gabriela (advisor)
The aim of the bachelor thesis is to describe and evaluate the used sources of financing the construction contract, to propose possible financing alternatives and final evaluation of used financial resources against alternative sources. The theoretical part deals with private and public procurement, investment decisions, sources of financing the construction contract and state subsidy policy. The practical part describes the company's private contract. It analyzes the financing of the contract and evaluates the financial resources used against the alternative.

Characteristics of inter-individual relationship (friend vs. rival) in red deer and its effect on agonistic behavior and endocrinological feedback
Peterka, Tomáš ; Bartoš, Luděk (advisor) ; Fuchs, Roman (referee)
Red deer males aggregate for a major part of a year to bachelor groups. Social position - Rank - is unstable in these groups. Previous experiments revealed that rank modulated by agonistic behaviour influences antler growth and antler cycle timing. Antlers are secondary sexual characteristics of the deer family and one of the fastest growing tissue in the vertebrate taxa. Their development is modulated by androgenic hormone, testosterone. In our experiment, we observed agonistic behaviour of 19 males. They were equipped with GPS collars and regularly handled for blood samples and downloading of telemetrical data. Based on statistical analysis, we found that in our bachelor group 13 stags kept similar interindividual distances which did not exceed 22 metres ("Closest associates"), whereas the rest of the group moved tens of metres away ("Wanderers"). In regard to the number of agonistic interactions and the interindividual relationship, which arose from that, we divided the bachelor group on "Friends" (˂9 interactions) and "Rivals" (≥9). We found that the number of interactions depended on average distance among males in groups divided by dyadic relationship ("Friends" and "Rivals"). With increasing distance, "Rivals" increased the number of interactions, while "Friends" did not show this trend....
Motivational aspects of FTVS student's increased interest in skydiving and paragliding
Bartoš, Libor ; Dvorský, Jaroslav (advisor) ; Čadová, Libuše (referee)
Title: Motivational aspects of FTVS student's increased interest in skydiving and paragliding Objectives: The main objective of this work is to define in theory the psychological terms connected with motivation based on studied literature and then to make a research focused on identifying the motivational aspects of FTVS UK students to participate in the skydiving and paragliding courses. Another objective is to compare these aspects in the paragliding group and the skydiving group. Methods: The method I used in an empirical part of the thesis to collect data was the method of non- standardized questionnaire. The researched object was formed by two groups of FTVS UK students. The first group was created by students of skydiving basic course and the other one was created by students of paragliding basic course. The total number of respondent students was 65. Results from the questionnaire were analyzed by using Excel spreadsheet, primarily by a frequency and average functions. Results: I have found out that most students don't have just one motivational aspect to practise these sports, but we can mark out several groups of these aspects which appear by each student in certain proportion. After that, it was possible to identify which aspects are dominating in the paragliding group and which are...
Characteristics of inter-individual relationship (friend vs. rival) in red deer and its effect on agonistic behavior and endocrinological feedback
Peterka, Tomáš ; Bartoš, Luděk (advisor) ; Fuchs, Roman (referee)
Red deer males aggregate during the period of antler growth to bachelor groups. Social position - Rank - is unstable in these groups. Previous experiments revealed that rank modulated by agonistic behaviour influence the antler growth and antler cycle timing. Antlers are the secondary sexual characteristics of the deer family and one of the fastest growing tissue in vertebrate taxa. Their development is modulated by androgenic hormone, testosterone. In our experiment, we observed agonistic behaviour of 19 males. They were equipped with GPS collar and observation lasted for two hours in the evening an in the morning, once or twice a week from the end of May to the end of August. Deer were handled regularly for blood samples and downloading the telemetrical data from collars. Base on a statistical analysis we found that in our bachelor group 13 stags kept similar interindividual distances which did not exceed the 22 metres level. These stags - the closest associates - differed in the sum of agonistic interactions. Those who reached 8 or less interactions were called Friends, while subgroup of the others reaching much more interactions were classified as Rivals. We found that number of interactions depended on average distance among males in groups (Friends and Rivals). Rivals with increasing distance...
Hormonal Aspects of Antler Growth Regulation
Kužmová, Erika ; Bartoš, Luděk (advisor) ; Petr, Jaroslav (referee) ; Kierdorf, Uwe (referee)
Hormonal aspects of antler growth regulation Erika Kužmová Abstract Deer antlers are the only mammalian organ that completely regenerates and therefore they became an object of rising interest as a potential model for bone growth and development. In recent years, it has been confirmed that annual regeneration of the antler is initiated from the stem cell niche localised in the pedicle periosteum. Antlers grow to the length at the tip. Only a little is known about endocrine stimulation of antler growth and some discrepancy has arisen between in vivo and in vitro studies over the decades. As the secondary sexual character, the antler cycle timing and growth are linked to seasonal levels of testosterone. Since the levels are at their minimum during the antler growth phase, according to many mainly in vitro studies, insulin-like growth factor-1 (IGF-1) tends to be accepted as the "antler stimulating hormone". Since the conclusion about the role of IGF-1 was contradictory to previous opinions and also in contrast with our own experience, we aimed to verify the role of IGF-1 in vitro. Our ex- periments were based on existing in vivo studies demonstrating the importance of testosterone, even in its low levels, and on the hypothesis that testosterone should be the "antler stimulating hormone". We performed in vitro...
