The effect of agri-environmental schemes on biodiversity
Vodička, Jan ; Reif, Jiří (advisor) ; Kindlmann, Pavel (referee)
The aim of thesis is summary of current results of scientific publications evaluating effectiveness of agri-environmental measures in the relation to biodiversity. This work deals with this issue in Europe, characterizes the situation in selected European countries and evaluate the effectiveness of compensation schemes and individual measures on selected groups of organisms. It also deals with the factors influencing the effectiveness and methodical approaches of evaluation studies. Results of studies suggest a low to medium efficiency of allover measures for plants and invertebrates and low efficiency for birds. Conversely targeted measures had a high efficiency, but their overall significance was very low due to small proportion of land compared to the horizontal measures.The worst situation was in the Netherlands, in other countries the results were relatively similar.
The optimal route search under several criteria
Vodička, Jan ; Fiala, Jiří (advisor) ; Kolman, Petr (referee)
Common methods of optimal route search are described in the thesis. Also, existing procedures used in problematics of transportation networks are mentioned. A nonlinear price function is proposed, which enables the user to specify their own preferences of any criteria (length, time, cost, etc.). Moreover, necessary modifications of common optimal route searching algorithms are presented. A method for propagation of maneouvres of arbitrary length into the transportation network is shown. This method enlarges nodes and vertices sets by amount linearly proportional to number of nodes involved in maneouvre set. Also, a general method diminishing the number of edges, which have to be encountered during optimal raute search process, is proposed. Precalculated edges sets are used to gain this goal. Proposed thesis contains three methods solving specific aspects of optimal route search in transportation networks. While the first method, when applied in practice, can bring limitations of processable data size, the other two procedures forrn the basis of a navigation system. Powered by TCPDF (www.tcpdf.org)
Factors contributing to interindividual differences in olfactory abilities and odour awareness
Nováková, Lenka ; Havlíček, Jan (advisor) ; Lukavský, Jiří (referee) ; Vodička, Jan (referee)
The main body of the thesis deals with selected factors underlying the considerable variability in human olfactory abilities and some odour awareness-related measures, addressed in samples ranging in age from middle childhood to young adulthood. The thesis consists of two parts. The first part (Chapter 1), first presents the major advances and developments that brought about something of a renaissance of scientific interest in the human sense of smell, including the recent proliferation of psychophysical studies, both basic research and clinical. Next, an outline of olfactory psychophysical measures and related olfactory abilities that are of relevance to the studies presented in this thesis is provided. Subsequently, the selected factors contributing to interindividual differences in olfactory abilities, that have been addressed by this thesis, are reviewed, namely the effect of sex (or gender), which is approached from a developmental perspective, childhood gender nonconformity, and personality. Finally, intraindividual fluctuations in olfactory performance are also mentioned in brief. Next, the focus shifts to odour awareness by first introducing the various approaches that can be adopted to get closer to the real-life context as opposed to laboratory setting (where most olfactory studies continue to be...
Development and use of non-destructive testing methods from the point of view of forensic engineering
Bílek, Petr ; Vala, Jiří (referee) ; Vodička, Jan (referee) ; Hobst, Leonard (advisor)
Concretes reinforced by, using distributed steel reinforcements (fibres) are known as fibre-concrete. In case of disturbances or accidents of concrete structures reinforced with wires, it is necessary to carefully examine the actual implementation of dispersed reinforcement. Fibre concretes belong to modern building materials whose possible applications have not been fully utilized so far. Have been mainly used for floor structures loaded with factory halls and warehouses. Recently, thanks to well-known physical and mechanical properties of fibre-concrete, there were numerous attempts of designers, and namely investors, to utilize this kind of materials for support structures either. Favorable properties of wire-concrete can be utilized if there is a necessity to increase the resistance of concrete to stresses exceeding its strength, cyclic stress or impact stress. Daily practice shows to prove that the applications of fibre-concrete in such structures lead to the economic success. Necessary condition for successful application of steel fiber reinforced concrete in constructions however consists in its uniform dispersion, a homogeneous distribution of the wires throughout the volume of the structure. In case of inappropriate processing and deposition of the mixture during the manufacturing process fiber-concrete structures, the fibers are often unevenly distributed. Wires itself represent unfavourably shaped mixture components and they are extremely deteriorating its workability. A grouping of wires may be encountered as well, which reduces the overall homogeneity and the quality of steel fiber-concrete structures. If the homogeneity of fibre-concrete is not kept, the material possess different properties in various parts of the structure (for example, tensile strength), which can lead to defects in the structure (generation and development of cracks). The relevant lower reliability of the structure which is caused by unequal distribution of fibres (wires) in concrete volume can lead to damage of the property as well as the safety and the human lives can be jeopardized. Hence it is necessary to secure the effective control of the fibre-concrete homogeneity in ready support fibre-concrete structures. Contemporary homogeneity control is still ongoing on fresh blends, but if the fibre-concrete hardened and is a part of the construction, no known reliable methods are currently in available to test the homogeneity of the fibre-concrete on the structure without its destruction. The methods developed to control the concentration of wires in wire-concrete structures are based mostly on magnetic or electromagnetic properties of wires. The thesis deals with the development of the magnetic method in situ using permanent magnets for monitoring the distribution of fibers in hardened steel fiber-concrete structures. The test principle is based on measurements of the changes in magnetic field strength of permanent magnets which are induced by a change in wire distribution in steel fibre-concrete structure. Test is characterized as a so called local- failure- test using a small diameter core drill. In this sense it is a semi-destructive method.
Association between olfactory and cognitive abilities in elderly individuals
Babuská, Anna ; Havlíček, Jan (advisor) ; Vodička, Jan (referee)
During the process of aging, the human mental and physical abilities decline. Olfactory abilities are not an exception. A significant decrease of olfactory capabilities in patients with Parkinson's disease was firstly observed a few decades ago. After the discovery of the relationship between olfactory abilities and cognitive abilities in patients with neurodegenerative disease, the same relationship was also found in healthy aging people. It seems that the factors causing the decline of cognition foremost affect the olfactory functions. A number of studies suggests, that this could lead to a possibility of prediction of the future cognitive decline through the assessment of olfactory decline. Our research followed the results of these studies as a part of the NANOK study. Testing of the smell abilities was done in 2014 and 2015. Participants were screened with the Sniffin 'Sticks. Cognitive functions were tested with an extensive battery of cognitive tests. The processiong of data was divided into two parts. In the first part we tested the olfactory identification and discrimination relationship with the general cognitive abilities and the level of the executive functions. In the second part we tested the possibility of prediction of cognitive functions using the smell identification and discrimination...
The compact city - rehabilitation of the urban area surrounding the historic center of Brno
Vodička, Jan ; Ležatka,, Lukáš (referee) ; Pavlovský, Tomáš (advisor)
The goal of the diploma thesis is to design a form of redeveloped urban area adjacent to the historical city centre of Brno. The design follows the tradition of the compact city and its development from the medieval age until the 19th century. Mixed functions, preference of non-motorised and public transport, vital shopping streets with greenery, permeability and spaces without barriers are characteristics for the proposed city of short distances. The design has its own distinctive approach to the plot, conceptually differing from the valid local development plan. I do not believe that the important animating impulse for the underdeveloped district of Brno-Zábrdovice should consist of tearing down existing buildings and replacing them with a new thoroughfare duplicating the internal city ring road.
Model of spontaneous vegetation development in post-mining heap
Vodička, Jan ; Frouz, Jan (advisor) ; Brůna, Josef (referee)
Predictability of primary succession in post-mining sites is needed for choosing appropriate restoration method. This study models 18 years of spontaneous succession on a post mining heap in Sokolov in the Czech republic with using historical aerial photographs and spatially - analytical methods. Each photograph has been georeferenced and classified manually into several categories based on the tree density. Three spatial models that applied different population growth equations and seed diffusion from the near neighbourhood has been developed. All models were able to predict spatial distribution of trees with solid accuracy, however, predictability were decreasing with time. The best results corresponded with 40% agreement on average from all years and more than 50% for some individual years. Keywords: spontaneous succession, spatial models, post-mining sites

Association between olfactory abilities, arousal and orgasmicity in women
Hájková, Martina ; Martinec Nováková, Lenka (advisor) ; Vodička, Jan (referee)
Olfaction plays an important role in human mate selection or in ratings of sexual attractiveness of potential mates. Many studies suggest that olfaction is associated with human sexuality and arousal as well, especially in women, for whom the perception of odors is an important aspect not only in mate selection, but also in sexual context. There are steroids called 16-androstenes, which have an unique importance in this issue. These steroids, produced by the apocrine glands, are compounds of human body odor. The aim of the empirical part of this thesis is to research the associations between olfactory abilities and sexual function in women, especially with particular focus on the association of olfactory sensitivity (particularly to androstadienone as well as in general), orgasmicity and arousal, which are two major domains of sexual function. Participants were 90 heterosexual and coupled female students aged 21-30. All participants were tested during the follicular phase of their menstrual cycle. The Sniffin Sticks olfactory test was employed to assess the general olfactory functions. Among others, olfactory sensitivity to androstadienone was measured, as well as the perceived intensity and hedonicity of androstenone, androstenol and andostadienone. Participants filled out set of questionnaires...
