Helical symmetry and the non-existence of asymptotically flat periodic solutions in general relativity
Scholtz, Martin ; Bičák, Jiří (advisor) ; Krtouš, Pavel (referee) ; Fraundiener, Jörg (referee)
1 Title Helical symmetry and the non-existence of asymptotically flat periodic solutions in general relativity Author Martin Scholtz Department Institute of theoretical physics Faculty of Mathematics and Physics Charles University in Prague Supervisor Prof. RNDr. Jiří Bičák, DrSc., dr. h.c. Abstract. No exact helically symmetric solution in general relativity is known today. There are reasons, however, to expect that such solutions, if they exist, cannot be asymptotically flat. In the thesis presented we investigate a more general question whether there exist periodic asymptotically flat solutions of Einstein's equations. We follow the work of Gibbons and Stewart [3] who have shown that there are no periodic vacuum asymptotically flat solutions an- alytic near null infinity I. We discuss necessary corrections of Gibbons and Stewart proof and generalize their results for the system of Einstein-Maxwell, Einstein-Klein-Gordon and Einstein-conformal-scalar field equations. Thus, we show that there are no asymptotically flat periodic space-times analytic near I if as the source of gravity we take electromagnetic, Klein-Gordon or conformally invariant scalar field. The auxilliary results consist of corresponding confor- mal field equations, the Bondi mass and the Bondi massloss formula for scalar fields. We also...

The Study of Expression and Function of Selected Nuclear Receptors in Caenorhabditis Elegans
Vohánka, Jaroslav ; Kostrouchová, Marta (advisor) ; Nedvídek, Josef (referee) ; Mandys, Václav (referee)
6 Abstract: The genome of Caenorhabditis elegans encodes more than 280 nuclear hormone receptors (NHRs) in contrast to the 48 NHRs in humans and 18 NHRs in Drosophila. The majority of the C. elegans NHRs are categorized as supplementary nuclear receptors (supnrs) that evolved by successive duplications of a single ancestral gene. The evolutionary pressures that lead to the expansion of NHRs in nematodes, as well as the function of the majority of supnrs, are not known. Here, we have studied the expression of seven genes organized in a cluster on chromosome V: nhr-206, nhr-208, nhr-207, nhr-209, nhr-154, nhr-153 and nhr- 136. Reverse transcription-quantitative PCR and analyses using transgenic lines carrying GFP fusion genes with their putative promoters revealed that all seven genes of this cluster are expressed and five have partially overlapping expression patterns including in the pharynx, intestine, certain neurons, the anal sphincter muscle, and male specific cells. Four genes in this cluster are conserved between C. elegans and C. briggsae whereas three genes are present only in C. elegans, the apparent result of a relatively recent expansion. Interestingly, we find that a subset of the conserved and non-conserved genes in this cluster respond transcriptionally to fasting in tissue-specific patterns....

Individual units of the Integrated Rescue System and preclinical intensive care in drowning - the Police of the Czech Republic, the Fire Rescue Service, the Water Rescue Service - Czech Red Cross
PROCHÁSKA, Pavel
The South Bohemia region is well known for its rivers, lakes and dams. With these great water values it is difficult to prevent drowning, search and rescue work is also influenced by the vast river system. The main goal of my research was to map the technical equipment, personal proficiency and comparing the professional qualifications of the Police force of the Czech Republic, the Fire Rescue Service and the Water Rescue Service in the range of an appointed theme. I chose the qualitative analysis method. The research group consisted of nine individuals {--} members of the researched organizations. They answered my questions very uniformly. I wanted to discuss the relevant topic with the respondents and get to know their opinion. Totally contradicted information was not recorded. Data collection was in the form of interview recordings on a Dictaphone and worked into text. The research conclusions are quite clear. In all respects the Police of the Czech Republic, the Fire Rescue Service and the Water Rescue Service are able to help in drowning cases. Some of these units are relatively well equipped as is necessary (the Fire Rescue Service and the Water Rescue Service), other not so well because of the principal aim (the Police of the Czech Republic). An interesting issue can be noted in both professional organizations (the Police of the Czech Republic and the Fire Rescue Service) about assistance and cooperation with the Water Rescue Service in the case of first aid and help providing. It is unusual that this last organization mentioned is not supported by the government. The research proved elementary disparity between the specialization with great abilities and struggle for existence which they meet every day in the case of the Water Rescue Service. Better legislation could be the answer for their financial difficulties. There is also disproportion in preventing people from doing unsafe activities; a member of the Water Rescue Service can only recommend the people to avoid such dangerous behaviour, but by law he can not force the individuals to obey to his words. The law warrants only this procedure which is astounding.

Martin Anton Lublinský (1636-1690) as a designer of prints. Views into baroque graphics of the latter half of the 17th century
Zelenková, Petra ; Horyna, Martin (advisor) ; Preiss, Pavel (referee) ; Royt, Jan (referee)
This work deals with one of the most important central European print designers of the latter half of the 17th century, the painter and draftsman Martin Anton Lublinský (1636- 1690). A native Silesian, who settled in Olomouc, where in 1664 he entered a cloister of the Augustinian canons, and then devoted the rest of his life to the creation of art. Lublinský has been at the forefront of Bohemian art history research in the last decade. This was due to several reasons. One of them is Lublinsky's scattered and in some ways founding role in the baroque painting and drawing of 17th century Moravia. Another is an increasing number of Lublinsky's known art realizations. Especially engaging is the profusion of iconography in Lublinsky's works. The main aim of this work was twofold, to assemble a comprehensive catalogue of all known prints drafted by Lublinsky, including related drawings and drafts, and secondly, to provide a thorough interpretation of these prints. Each catalogue note offers a detailed iconographic analysis; also provided are any known commission details and specifics relative to the historical and art historian context. The catalogue's main thrust is the thesis prints drafted by Lublinsky. The ambitiousness of composition and the sheer amount of these prints represent the apex of Lublinsky's...

The work of Gregory Bateson in the context of contemporary culturology
Kučera, Marek ; Soukup, Martin (referee) ; Soukup, Václav (advisor)
The thesis is an attempt to relate the work of Gregory Bateson to the concept of culturology as it is being developed at the Department of Cultural Studies at the Faculty of Philosophy and Arts at Charles University in Prague. It consists of three relatively independent parts each of them dealing with particular science with which Bateson was concerned - anthropology, psychology and ecology. In the first part, notions of function, cultural structure, ethos, eidos and schismogenesis are discussed. It is asserted that Bateson's anthropological work represents integration of British functionalism and American configurationism and that the concept of cultural structure anticipates French structuralism. The second part is concerned with Bateson's concepts developed during the forties and fifties which related mostly to psychological topics, especially his best known double bind theory. It also treats Russell's type theory that plays a central role in most of Bateson's works. And finally, the ecological part deals with Bateson's epistemology and evolutionary theory. In addition to his major epistemological notions - "a difference which makes a difference" and the fundamental distinction of Pleroma versus Creatura, which he borrowed from famous Swiss psychologist Carl Gustav Jung - his picture of new...

Graves of Bylany culture from Lovosice against a background of local settlement
Půlpán, Marek ; Koutecký, Drahomír (referee) ; Salač, Vladimír (advisor)
The rescue archeological research on the locality Lovosice II - Industrial Zone Aoyama under the direction of The Institute of Archeological Research and Preservation of Historical Monuments in Most was a material base and resource for the labour of a bachelor degree. The Institute granted also the funeral findings from the older Iron Age, the three graves of Bylany culture were chosen for this labour. The archeological locality Lovosice (Czech republic, Region of Ústí nad Labem, township Litomice) laying in geomorphologic structured countryside of eské stedohoí belongs to one of the most endangered and at the same time the most explored prehistoric territory of the north-west Bohemia. There is documented practically continuous habitation from Neolithic age to the present and also the intersection of the distance trading ways. The Bylany culture is above all known for its funeral findings. The group of the amply equipped burials with the wagons, yokes, toggeries and armature are specific for this culture. In addition to this group the low equipped graves were documented, in them the richest findings were missing and the synthetic works don't pay frequently enough attention to them. To refer to the position of the relatively low equipped graves was the principal aim of this labour. We solved the question of...

Lagomorpha (Mammalia) of the Pliocene and Pleistocene of Europe: a revision of selected taxa
Čermák, Stanislav
1 Lagomorpha (Mammalia) of the Pliocene and Pleistocene of Europe: a revision of selected taxa Stanislav Čermák The dissertation (accepted as a rigorous) thesis is concerned with selected taxa of lagomorphs, an ancient conservative group of herbivorous mammals, in the Pliocene and Pleistocene (Ruscinian - Biharian) of Europe. Using techniques of detailed morphometric analysis of 42 metric and 14 non-metric features, the fossil material (mostly new unpublished) of dental and cranial remains of Lagomorpha from 38 localities of Central, Southeastern, and Eastern Europe covering stratigraphically the period from Early Ruscinian to Late Biharian (MN 14 - Q2) was analyzed in detail. The work provides: (1) Ochotonidae - a detailed revision of poorly known pikas of "Ochotona group" from the Pliocene (Ruscinian) of Eastern and Southeastern Europe (i.e. Ochotona antiqua, Pseudobellatona, and Ochotonoma); a detailed morphometric survey of all currently available fossil record of Ochotona from the Pleistocene (MN 17 - Q1) localities of the Czech and Slovak Republics, it enlarges knowledge about these ochotonids based, up to now, on the relatively scarce fossil record from France, Germany, Poland, and Hungary; (2) Leporidae - a comprehensive revision of Hypolagus - the important and dominant genus of Leporidae in the...

A Comparison of Short Stories by Katherine Mansfield and Elizabeth Bowen
Synková, Blanka ; Wallace, Clare (advisor) ; Nováková, Soňa (referee)
This thesis compares short stories by the New Zealand-born author Katherine Mansfield (1888-1923) and the Anglo-Irish writer Elizabeth Bowen (1899-1973), namely Mansfield's short story collection Bliss and Other Stories (1920) and Bowen's The Demon Lover and Other Stories (1945). It aims to offer a relatively complex view: it discusses the form as well as the content of the short stories, illustrating the arguments with concrete examples from the short stories, famous ones as well as less known; it suggests various influences that may reflect in the short stories, it offers opinions of notable critics on the individual authors and it also occasionally mentions the authors' own opinions on their work and literature in general. There are three chapters in the body of the thesis. One of them provides contextual information about the possible influences that may have shaped the authors' writing as well as about some critical approaches to their work. The other two chapters analyse the form and content of the stories, respectively. The discussion of formal aspects of Mansfield's and Bowen's short stories focuses on various features of the short stories that may be described as impressionist or lyrical, and on technical devices that may be compared to film. The analysis of content is concerned especially...

John Wyclif, Jan Hus and Martin Luther as apocalyptic prophets
Šárovcová, Martina
Illuminated music manuscripts created in 16th century Bohemia and Moravia for Utraquist literary brotherhoods represent a relatively rich collection of artefacts from the period before the Battle of White Mountain. The commonly illuminated incipits of these manuscripts also included introits dedicated to the feast of the Bohemian martyrs Jan Hus and Jerome of Prague. Several illuminations dating from the third quarter of the 16th century represent a richly documented iconography of Jan Hus. The first volume of the "Lesser Town Gradual" from the years 1569-1572 (Prague, National Library, sign. XVII A 3) also belongs to these manuscripts, due to its arrangement and selection of topics. Depicted in its bordure is John Wyclif striking a spark, Jan Hus lighting a candle with a twig and Martin Luther with a shining torch. With regard to the other lesser known literary and visual variants of the motifs of kindling light, the topic is interpreted in accordance with the interpretation of biblical verses in Chapter 11 of the New Testament´s Apocalypse about the calling of two witnesses and prophets at the beginning of the end of the world (The Book of Revelations 11, 3-4). The figures of John Wyclif, Jan Hus and Martin Luther can be interpreted in eschatological contexts of awaiting the second advent of Christ as apocalyptic prophets called by God and witnesses to the (Evangelical) truth who are bringing light to the darkness of the last time.
