Gallery aviation technology and traditions of aviation at the airport Medlánky in Brno
Bělehradová, Věra ; Žalmanová, Petra (referee) ; Šindlar, Jiljí (advisor)
Sport Airport complex Brno-Medlánky is nestled in the undulating hilly terrain in fields just beyond populated areas in Brno-Medlánky. The history of the airport dates back to 1924 when it was built the first wooden hangar for training purposes glider flights. Current state urban of airport is orderless. The aim is to streamline the complex and give it the order, allowing easy and efficient orientation in the space. The main intervention was the creation of a new central building - Aviation Museum. The concept of the design is based on the division of the whole area into two branches - communication axes, based on the mass preserved historic wooden hangars. Between the two communication arms is inserted a central axis on which is located the heart of the complex - Aviation Museum. It is a building organic form, inspiring axially symmetric wingspan (bird, airplane, beetle). It is this symmetry axis of the building creates a view towards building on the runway. Mass of the building used by the sloping terrain and is partially sunk under the ground. Building volume follows an upward slope from the outside and blends with the surrounding terrain. The internal layout consists of three floors, one of them is completely sunk below ground level and second half. The main entrance to the gallery is located in the uppermost floors, the direction of the exhibition is therefore directed downwards into the basement. The exposition is divided into six parts: RC models exposure, gliders exposure, powered aircraft exposure, screening room, children's exposure and air trainers. Other areas consist of building technical facilities. In the basement there is a workshop with aircraft lift, with the possibility of placement unexposed aircrafts. The supporting system of the building consists of two parts: reinforced concrete tubs and arched steel structure with a span of 50m.
Influence of avian Plasmodium on their hosts
Dulavová, Kristýna ; Svobodová, Milena (advisor) ; Vinkler, Michal (referee)
Avian malaria parasites of the genus Plasmodium are unicellular (and intracellular) protozoans of the group Haemospororida, using a blood-sucking insect (mosquito) as a vector and a bird as a vertebrate host. The effects of this disease, together with avian pox, have greatly influenced endemic populations of Hawaiian birds after introduction of a suitable vector to the islands by a human hand, leading to a drastic extinction of bird species; most of the remaining Hawaiian endemic species are now endangered. Apart from that, avian malaria is distributed nearly all over the world, infecting a variety of different hosts. This thesis is focused on the influence of avian malaria parasites mainly on their avian hosts. The most severe patologies caused by Plasmodium are associated with blood stages causing serious anemia in birds. More pathologies are connected with exoerythrocytic stages in the endothelial cells in various organs and are accompanied with external signs such as lethargy, respiratory distress, weakness, inappetence, sometimes weight loss and so on; different plasmodium species-bird host combinations have different outcomes. An interesting issue is the emerging tolerance against avian malaria in Hawaii Amakihi (Hemignathus virens), a species occupying low elevation areas of Hawaiian...
Birds in teaching at secondary schools with new knowledge in the field
Weiser, Jiří ; Řezníček, Jan (advisor) ; Kopřivová, Kateřina (referee)
In the introduction of theoretical part of diploma thesis is tabularly summed up the systém of birds classification. Other parts are focused not only on general issues and commonly used themes in school textbooks, popular literature and educational media, but also to highlight specific features, characteristic only for the birds. These themes are historical and evolutional questions, cover morphology, the effect of the senses, body structury and function of organs. In detail is analyzed the issue of body composition and skeletal system of birds. In the final sections are mentioned specialities in the behavior and communication between birds and their habits. The practical part includes a SWOT analysis of available textbooks for the four-year gymnasium with regard to the chapters and information about the animal class of birds. The data analyzed in the textbook can only be considered as basic with need to extend and complement by the teacher. Attached to the diploma thesis are two presentations in Powerpoint, containing basic information and specific features, characteristic only for birds. The presentations are created worksheets. For reference classes was developed as a lab practical examination of selected thematic blocks, memorized theoretical interpretation. Students' knowledge of the...
Bird mortality at transparent barriers
Houdová, Monika ; Reif, Jiří (advisor) ; Koleček, Jaroslav (referee)
Bird mortality at transparent barriers (noise barriers or common house windows) is undoubtedly very important environmental issue, because of the rapid development of human society and even more rapid growth of very dangerous places for birds. At this time there is no review article yet, that would synthesize each sub-study on the extent to which individuals can die on those obstacles, which factors are critical for the ability of obstacle avoiding, how much collision threaten the vitality of bird populations and if we can prevent such unintended damage. This bachelor thesis handle with these questions as a literary review. From the available information we can suggests that the most important factor is migration behavior of birds, individuals migrating through the night are much more at risk than those migrating during the day, mostly because of light pollution, which can confuse them. The most dangerous time of year in this direction is clearly autumn, and that also relates with migration. Population losses caused by collision to the transparent barriers can be up to 20 % of the total population per year. Thesis in addition to a summary of available information on the issue proposes and evaluates possible preventive aplications, which may further serve to effective conservation for birds among...

The role of biting midges in avian blood parasites transmission
Chobotová, Kristýna ; Brzoňová, Jana (advisor) ; Kočišová, Alica (referee)
Biting midges of the genus Culicoides (Diptera: Ceratopogonidae) are hematophagous in- sects mainly important as vectors of viral diseases of farm animals. They have shifted to the forefront of scientific interest in the Czech Republic primarily in relation to the Bluetongue Virus spread since 2007. However, they have been often ignored as vectors of parasitic infec- tions, especially if these are not pathogens of economic importance. In birds, which are the focus of this bachelor's thesis, biting midges are the most significant vector mainly for the genus Haemoproteus, they transmit at least 24 species of these protozoa. On the other hand, they are proven vectors for only one species of the genus Leucocytozoon - L. caulleryi. Trans- mission has been proven for three species of the genus Trypanosoma - T. avium, T. bennetti and T. everetti. Biting midges also transmit helminths of the family Onchocercidae, they play a role as vectors for the genera Eufilaria, Chandlerella and Splendidofilaria. The goal of this bachelor's thesis is to gather information about biting midges as vectors of avian blood parasites - protozoa of the genera Haemoproteus, Leucocytozoon and Trypanosoma and helminths of the family Onchocercidae. Key words: biting midges, parasite, vector, host, bird, Haemoproteus,...
Verification and numerical simulation of advanced composite inlet in compliance of airworthiness impact requirements
Doubrava, Radek ; Oberthor, Martin ; Raška, Jan ; Bělský, Petr ; Doubrava, Karel ; Dvořák, Milan
Bird or hail stone strikes are an important phenomenon which must be considered during aircraft design. Most of major bird or hail strike incidents result from engine ingestion. As engines are the sole thrust providing mechanisms of an aircraft, it is critical to investigate and mitigate the effects of bird or hail strikes on engine inlets and systems to the greatest extent possible. The article presents application of test verified numerical simulation for design and full-scale test verification of advanced composite air inlet for new generation of jet trainer aircraft from point of view of high speed impact resistance. The physical bird and hail impact tests were performed at the Czech Aerospace Research Centre (VZLÚ) according to airworthiness requirements. The measurement during impact test were performed by high-speed camera, Fiber Bragg Grating (FGB) sensors and strain gauges in cooperation with Czech Technical University (CTU) in Prague. The results from full-scale bird and hail strike tests were compared with numerical simulation.
