The purpose of this master thesis in history was to examine the use of history of an Indian queen, the Rani Lakshmi Bai of Jhansi. The Rani Lakshmi Bai was born in Banaras and married a king – the Raja of Jhansi. The Rani Lakshmi Bai fought against the British during the first war of independence year 1857-58. Recently, a memorial has been built at her supposed birthplace in Banaras, more than 150 years after her death. This development has raised several questions about the use of history of the Rani Lakshmi Bai. How has the use of history of Rani Lakshmi Bai changed? Why has it become relevant to build a statue of the Rani now and not before? The purpose of this study has been answered with the help of oral history and text analysis. Firstly, this has been done, by examining the knowledge of people from Banaras and Jhansi as well as through their perceived image of the Rani Lakshmi Bai. Twenty people from Banaras and four people from Jhansi have been interviewed. Secondly, the institutional level information has been examined which is presented in educational textbooks and newspapers like the local newspaper Aaj and the national newspapers The Hindu as well as The Times of India. The results show that the level of historical knowledge about the Rani is low, though the love and affection for her are great. The use of history of the Rani Lakshmi Bai has been as a freedom fighter, a role model in different contexts and a symbol, as well as an inspirational source of women empowerment. There is also a political use of the Rani. All these uses of history in combination with the increased economic interest in the neighbourhood of Assi in the city of Banaras made it relevant and possible to build a monument of the Rani Lakshmi Bai in present time.

This diploma thesis deal with phase of construction, which is foundation and upper construction of apartment building Komenského in Liberec. Building is situated in built-up and green area. Foundation circumstances is half difficult because of lower water included in soil. In this phase, we use formowork for columns, walls and roof. Used formwork is from Peri company, Quatro, Trio and Multiflex. There is suteren in the house, and because of lower water and high index of radon, we have to protect structure by compact waterproof isolation. This project contains formwork schematics and the time calculation needed to protect concrete until accomplishment. Other task is thermal review of constructions.

Ziel der vorliegenden Arbeit war es, die Zusammenhänge zwischen der molekularen Architektur, Morphologie und den mechanischen bzw. bruchmechanischen Eigenschaften in S-SB-S-Triblockcopolymeren und deren Blends und in PI-PS-Multipfropfcopolymeren herauszuarbeiten und damit einerseits einen Beitrag für das Verständnis der Struktur-Eigenschaftsbeziehungen in Block- und Pfropfcopolymeren zu leisten und andererseits Möglichkeiten zur Entwicklung neuer Materialien aufzuzeigen, welche besondere Eigenschaftskombinationen aufweisen und damit ein bedeutendes Interesse für industrielle Anwendungen hervorrufen. Für die Untersuchungen wurde dabei der PS-Außenblockanteil und das S/B-Verhältnis im SB-Mittelblock in S-SB-S-Triblockcopolymeren, die Thermoplast/Thermoplastisches Elastomer (TP/TPE) -Zusammensetzung in S-SB-S-Triblockcopolymer-Blends sowie die Funktionalität und die Anzahl der Verknüpfungspunkte in PI-PS-Multipfropfcopolymeren variiert. Zur Charakterisierung der Phasenmischbarkeit und der Morphologie wurden die dynamisch mechanische Analyse (DMA), die Transmissionselektronenmikroskopie (TEM) und die Röntgenkleinwinkelstreuung (SAXS) angewandt. Die mechanischen Eigenschaften wurden mit dem einachsigen Zugversuch untersucht. Bruchmechanische Untersuchungen erfolgten unter Anwendung der „Essential Work of Fracture“- (EWF-) Methode, welche als Konzept der „Post-Yield“-Bruchmechanik innerhalb der Fließbruchmechanik für duktile nanostrukturierte polymere Materialien sehr gut anwendbar ist und Aussagen zur Bruchzähigkeit der Materialien liefert. Zur näheren Charakterisierung des zeitaufgelösten Deformationsverhaltens sowie der Rissausbreitungskinetik wurden die Dehnungsfeldanalyse, eine Bruchflächenanalyse mittels Rasterelektronenmikroskopie (REM) sowie das Risswiderstandskurven-Konzept angewandt. Die Untersuchungen der S-SB-S-Triblockcopolymersysteme und der PI-PS-Multipfropfcopolymere konnten den signifikanten Einfluss der molekularen Architektur, der Blockzusammensetzung und des PS-Gehaltes auf das Phasenverhalten, die Morphologie und die Eigenschaften klar herausstellen. Durch die Variation dieser Parameter kann das Eigenschaftsspektrum von thermoplastisch zu elastomer eingestellt und somit sowohl TPs oder TPEs mit hoher Steifigkeit und Zähigkeit als auch TPEs mit superelastischem Charakter erzeugt werden. Daraus eröffnet sich ein breiter Anwendungsbereich dieser Materialien, welche aufgrund ihrer Transparenz und physiologischen Verträglichkeit auch interessante optische und gesundheitliche Vorteile mitbringen. Es konnte gezeigt werden, dass durch die systematische Variation der Architektur die gezielte Einstellung gewünschter Eigenschaftsprofile möglich ist. Die Arbeit leistet somit einen Beitrag zur Entwicklung anwendungsorientierter Materialkonzepte, welche ingenieurwissenschaftlich interessant sind. / The aim of this thesis was to study the relation between molecular architecture, morphology and (fracture) mechanical properties of S-SB-S triblock copolymers and PI-PS multigraft copolymers. Hence, this work should contribute to the understanding of structure-property-relationship in block and multigraft copolymers and thus offer possibilities for the development of novel materials with special properties interesting for industrial application. Within this study in the case of S-SB-S triblock copolymers the PS outer block content and the S/B ratio of the middle block, in the case of S-SB-S triblock copolymer blends the thermoplast/thermoplastic elastomer (TP/TPE) composition and in case of PI-PS multigraft copolymers the functionality and number of branch points were varied. For the characterisation of morphology and phase miscibility dynamic mechanical analysis (DMA), transmission electron microscopy (TEM) and small angle X-ray scattering (SAXS) were applied. Uniaxial tensile tests were carried out to investigate the mechanical properties. The fracture mechanical behaviour was studied using essential work of fracture (EWF) concept based on the post yield fracture mechanic principles, which is suitable to characterise fracture toughness of ductile nanostructured materials. The time resolved analysis of deformation and fracture behaviour was characterised qualitatively by strain field analysis, scanning electron microscopy (SEM) of the fractured surfaces and quantitatively by evaluation of the crack propagation kinetics and construction of R-curves. This study clearly highlights the significant influence of molecular architecture block composition and PS content on the phase behaviour, morphology and properties of S-SB-S triblock copolymers and PI-PS multigraft copolymers. By varying these parameters the property profile can be adjusted diversifying from thermoplastic to elastomeric and both TP or TPE materials with high stiffness and toughness and TPEs with super-elastic characteristics can be designed. Hence, fundamentally it offers a broad scope of application of these materials, in which physiological compatibility and transparency are added advantages. Thus, conceptually it could be shown, that by systematic variation of the architecture desired property profiles can be adjusted. Therefore the present work contributes to the development of application-oriented material concepts, which are interesting in engineering terms.

This research project centers around cinematic and societal representation of the automobile in post-war Swedish cinema and television. Due to political neutrality during World War II, Sweden’s economy benefited from an extensive surplus immediately after Germany’s capitulation in 1945. Economic prosperity was in return transferred onto Swedish society, which enabled an already high degree of motorization of Swedes in mid-1950s, while neighboring European countries struggled rebuilding overall infrastructures, basic food supply lines and often entire cities. Naturally, this would conclude that Swedes presumably had a favorable attitude towards cars from the beginning, ultimately being reflected in some sort of cultural memory. However, Stig Dagerman’s 1948 short story “To Kill a Child” (Att döda ett barn), later on realized as short film in 1953, outlines a rather suspicious and cautious attitude towards automobiles. Cars’ mass-media portrayal in Swedish cinema and television was analyzed with current AI-techniques, therewith observing notable changes in imagery, themes and attitudes surrounding cars over 30 years in history. Filmarkivet.se served as main source with 114 currently available media artifacts from 1950 to 1980, including a wide spectrum of footage i.e., weekly newsreels, private filmmakers’ collections, television commercials, movie trailers, political campaigns and documentary formats. This source material proved diversified in nature as well as redrawing accurately representations of Swedish mass media of its time as it varied between cinema and television, whilst focusing in on daily life of individuals or daily life in Sweden’s cities. While artificial intelligence object recognition helped identifying pertinent sections within a large corpus of film data, subsequently, a qualitative tf-idf-analysis of selected films based on speech-to-text output was conducted, counterbalancing quantitative research approaches.
