ARGUMENTS POUR UNE PRODUCTION TÉLÉVISUELLE À L’UNIVERSITÉ: UNE APPROCHE DES LANGUES ÉTRANGÈRES DANS L’ENSEIGNEMENT SUPÉRIEUR ILLUSTRÉE PAR DES FILMS EN ALLEMAND ET EN FRANÇAIS
Television plays an important role in teaching as well as in research of two departments at Saarland University: the Romance language department and the department of information sciences. Thus, the two department have developed a joint "University television project", historically the very first in Germany that broadcasts regularly in the context of a television station that covers an entire federal state within Germany. This paper presents the history, the goals and the types of emissions we broadcast. We have different approaches: one is the production of students that for example try to improve their intercultural and their language skills and deals with how to present information the most succesful way possible. The experiences inside and outside of the university are described.
Formale Charakteristika von Audiovisionssegmenten im multimedialen Umfeld
Die zunehmende Bedeutung von Bewegtbild auch im Umfeld multimedialer, computergebundener Angebote legt einen Vergleich mit den Angeboten der anderen Bewegtbildmedien, also des Kinos und des Fernsehens, nahe. Eine empirische Untersuchung lasst deutlich werden, dass die unterschiedlichen Rahmenbedingungen auch die Art und Weise verandern, wie die Filme wirken. Daher muss das semiotische Verhaltnis von Bedeutendem und Bedeutung bei der Produktion von Bewegtbildmedien in unterschiedlichen Kontexten jeweils mitberucksichtigt werden. Es mussen offenbar vor allem formale Unterschiede in der Gestaltung wie auch der inhaltlichen Darstellung berucksichtigt werden. Die Unterschiede beziehen sich auf formale Aspekte wie die Filmlange, auf die Bildgestaltung und das Schnitt-Tempo wie auch auf Probleme der Dramaturgie. Sie sind so deutlich, dass gar von einer historischen Entwicklung gesprochen werden muss, die sich in Gegensatzpaaren konstituiert. The increasing importance of time-based media in the context of computer-based, i.e. multimedia productions seems to urge research on the differences with other time-based media, cinema and television. Empirical research proves that the different channels also change the way of how those time-based media influence the user. Producing time-based media, therefore, has to be different in relation to the medium chosen, as each media changes the semiotic relationship between sign and significance, and therefore changes the necessities of how to produce and how to present the content. Differences can be found regarding the film length, the design, the speed of editing, and the dramaturgy. They seem to be quite contrasting and to represent a historic process.
Thorium-induced Anatomical and Histopathological Changes in Liver of Swiss Mice
ObjectivePresent study is aimed to investigate the anatomical and histopathological changes in liver tissues of Swiss albino male mice, one month after intravenous administration of thorium (232Th; 4 and 40 mg/kg).MethodsSynchrotron X-ray micro-CT imaging, CD31 immuno-cytochemistry, hematoxylin & eosin staining and Periodic acid-Schiff staining were performed to study changes in liver anatomy, blood vessels/capillaries, histology and glycogen content of liver, respectively.ResultsSynchrotron X-ray micro-CT imaging of liver showed loss of blood vessels in mice treated with thorium (4 mg/kg), which was more prominent at higher dose of thorium (40 mg/kg). These thorium-induced changes in liver were correlated with the decrease in CD31 positive cells and loss of tissue architecture. A dose-dependent increase in glycogen content was also observed in the liver of thorium-treated mice.ConclusionOur results provide novel insight about the effects of thorium on liver, which may have significant implications in understanding the mechanism of thorium thorium-induced hepatotoxicity.
