The Macroeconomic Impacts of the Selected Oil Shocks in the United States of America
Šikulová, Markéta ; Johnson, Zdenka (advisor) ; Tajovský, Ladislav (referee)
The aim of this study is to analyze macroeconomic impacts of four selected oil shocks on the United States economy and their subsequent comparison. The first part of this study deals with the theoretical background of supply shock, its influence on the economy, and the possible responses of economic policy. Furthermore, in the first part I focus on the historical events that led to the oil crisis, specifically on the OPEC oil embargo imposed on the United States, production cuts caused by the Iranian revolution, Iran-Iraq War and Persian Gulf War and on the demand as well as the supply factors that led to the oil shock of 2007-2008. The second part of this study presents the specific impacts of four selected oil shocks on the US economy and their comparison. Based on the findings, it was possible to confirm the hypothesis saying that past oil shocks, especially those that took place in the 1970's, had more negative impacts on the United States economy in comparison with those that happened more recently. In other words, that the effects of changes in oil prices have lessened over time. There are many reasons of this moderation, but the most important ones include more effective monetary policy response, the decrease in wage rigidities, and more recently also the decline of United States dependency on imported oil.

: Investigation of lymphocyte populations in the porcine small intestine
Kárová, Kristýna ; Šinkora, Marek (advisor) ; Javorková, Eliška (referee)
8 ABSTRACT Historically pig is allocated to a group of animals which use certain parts of their small intestine to acquire a fully developed primary B cell reperoire. Development of such primary repertoire is independent on the antigen presence and resembles the primary lymphopoietic activity of avian bursa of Fabricius. However, some findings concernig the pig's alignment in the above mentioned group suggest otherwise. This graduation thesis is focused on the investigtion of lymphocyte populations and subpopulations in the small intestine of germ-free and conventional piglets. The aim is to determine whether the percentage amounts of lymphocyte populations is dependent on the intestinal colonization. Using Flow Cytometry the significant differences between individual samples were assesed allowing us to conclude which parts of the small intestine could possibly be used for the development of B cell repertoire. Moreover, the status of isotype switching of B lymphocytes isolated from different intestinal parts was determined by the means of PCR analysis. Our data suggest that the small intestine colonization has a crucial role in development of all the main lymphocyte populations as well as some of their subpopulations. The greatest influence of colonization was observed concerning B lymphocytes and their...

The Liberation of Pilsen 1945 in Photography
Křenová, Tereza ; SILVERIO, Robert (advisor) ; JANOŠČÍK, Václav (referee)
This bachelor thesis deals with liberation of Pilsen in May 1945 by american army in photography. The aim of this thesis is finding and collecting archival materials and placing them in a historical-political context. Communist regime changed the portrayal of historical events and directly influenced the amount of exisiting photographs, documents and lives of those who created them. Important part of this bachelor thesis is working with those archival materials – particularly with photographs capturing arrival of Americans and their stay in Czechoslovakia at the end of WW2. Both professional and amateur photographers created valuable photographs as they witnessed the liberation of Pilsen. These photographs became in spite of communist propaganda a clear evidence that Pilsen was liberated by american army.

Introduction to bio art
Šperanda, Nina ; SILVERIO, Robert (advisor) ; JANOŠČÍK, Václav (referee)
Bio art is a contemporary art practice that works with living organisms (except humans) or is created in cooperation with living organisms. It is relatively new art movement that is rooted deeply inside the history of evolution, domestication of animals and plants, technological discoveries, their development and science. Never before was art questioning its ethics and aesthetics in such profound, molecular and sub-molecular way.
In this work I will consider the historical influences and conditions that led to current developments in the field. I will also try to explain the problematics of defining what bio art is and try to clarify the associated terminology. Most relevant and ground breaking works in the field will be mentioned as some new recent developments.
Aesthetics of bio art is also an important subject often set aside by the ado around ethics of it. It is an extremely important subject to be considered when talking about bio art and I will try to sketch out a brief outline of it with references to philosophy and contemporary bio art theory.

Arctic tundra dendrochronology
Lehejček, Jiří ; Svoboda, Miroslav (advisor) ; Monika, Monika (referee)
Historically unprecedented environmental change in the Arctic ecosystems is often given into the context of its past and possible future development. In the region where instrumental meteorological observations are scarce archives need to be investigated in order to address this issues. The comprehensive synthesis one of the archives: long-live circumpolar evergreen Juniperus communis L. shrub is presented here. 20 individuals from southwest Greenland were investigated at the cell anatomy level to understand the ecology of the species and unhide its potential for environmental and climate reconstructions. The findings are as follows:
i) Stop of exponential cross-sectional conduit-lumen widening with increasing age is in contrast with conduit-lumen nature of trees. This indicates that shrubs do not need to saturate their water and nutrient demands via traits of classical hydraulic conductivity law but rather developed different mechanisms. Extreme weather conditions result in prostrate growth form. However, different weather factors probably influence shrub growth differently: While snow and wind act mechanically (a), temperature influences the form of growth physiologically (b). a) So long as the young shrub stem has high resilience to bend back to an upright position after snow melt and so long as it can withstand the wind during the vegetation season it most likely grows upright and the conduit-lumens widen. b) Temperature, resp. freeze-thaw events are responsible for the shrubs preference of safety (finite size of conduit-lumens) over hydraulic efficiency, thus not allowing for more primary growth. All of these (and other) factors are apparently working together and the transition of vertical to more horizontal growth is gradual. As a consequence, the conduit-lumen sizes may not have to be further increased (due to ecophysiological restrictions possibly also must not) because water is no longer transported against gravity.
ii) Observed age/growth trend has to be taken into consideration for further employment of the wood anatomical parameter in paleoenvironmental studies. That is, shrub cell parameters can only be used for this purposes if correctly detrended. This allows for more accurate as well as longer reconstructions because youth trend was often neglected in reconstructions based on shrub annual-rings.
iii) The south-western Greenland Ice-Sheet (GrIS) melt rates reconstruction is presented for the whole 20th century. This part of GrIS is considered as the most active. According to the presented reconstruction current GrIS melt rates are not uncommon for the last century being comparable to first decades of 20th century. This finding is particularly important contribution to the debate on Atlantic meridional overturning circulation (AMOC). Too high fresh water inputs into the Northern Atlantic from GrIS melting may slow down or even stop the AMOC which would result in more continental climate in Europe. Presented results indicate that this threshold lies higher than observed current melt rates of GrIS.
Fascinating Juniperus comunnis species has shown to be able to address many ecological as well as environmental open questions and due to its longevity and abundant distribution has a great potential to become an important player in the Arctic research.

History of the North Czech philharmonic Teplice
Kolařík, Tomáš ; PANOCHA, Jiří (advisor) ; TOMÁŠEK, Jiří (referee)
In his master thesis the author provides a look into the history of The North Czech philharmonic Teplice, the only professional symphonic ensemble in the region of Ústí nad Labem, since 1948 until now. The work is divided into four main chapters. The first one gives an overview about the most significant conductors, which held a position of either a chief-conductor or a deputy. The second, crucial chapter brings an insight to the historical development of the orchestra, its changes and events, from the time of the re-establishment (1948) to the year 2016. In the third chapter, the author mentions the most important information about Ludwig van Beethoven music festival, of which The North Czech philharmonic Teplice is an organizer, and then gives a brief and incomplete list of the festival's seasons. The final chapter marginally sums up the work with the information about a new feature called "orchestra academy", inspired by the main czech orchestras. The thesis is attached with pictures showing the rehearsals and concerts environment in the time course and recent images of the orchestra, which enhance the possible plain and fact-like character of the whole work.

Stability and convergence of numerical computations
Sehnalová, Pavla ; Dalík, Josef (referee) ; Horová, Ivana (referee) ; Kunovský, Jiří (advisor)
Tato disertační práce se zabývá analýzou stability a konvergence klasických numerických metod pro řešení obyčejných diferenciálních rovnic. Jsou představeny klasické jednokrokové metody, jako je Eulerova metoda, Runge-Kuttovy metody a nepříliš známá, ale rychlá a přesná metoda Taylorovy řady. V práci uvažujeme zobecnění jednokrokových metod do vícekrokových metod, jako jsou Adamsovy metody, a jejich implementaci ve dvojicích prediktor-korektor. Dále uvádíme generalizaci do vícekrokových metod vyšších derivací, jako jsou např. Obreshkovovy metody. Dvojice prediktor-korektor jsou často implementovány v kombinacích modů, v práci uvažujeme tzv. módy PEC a PECE. Hlavním cílem a přínosem této práce je nová metoda čtvrtého řádu, která se skládá z dvoukrokového prediktoru a jednokrokového korektoru, jejichž formule využívají druhých derivací. V práci je diskutována Nordsieckova reprezentace, algoritmus pro výběr proměnlivého integračního kroku nebo odhad lokálních a globálních chyb. Navržený přístup je vhodně upraven pro použití proměnlivého integračního kroku s přístupe vyšších derivací. Uvádíme srovnání s klasickými metodami a provedené experimenty pro lineární a nelineární problémy.
