Charles Univerzity in Prague Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Technology Candidate: Veronika Müllnerová Consultant: Doc. RNDr. Milan Dittrich, CSc. Title of thesis: Impact of molecular weight and the grade of branching of aliphatic oligoesters on their hydrolytic degradation Theoretical part of the thesis deals with behavior, properties and applications of biodegradable polyesters, mainly copolymers of lactic and glycolic acid (PLGA). This part concerns degradation, erosion and release mechanism. Furthermore, it describes properties that influence the drug release kinetics from systems based on PLGA. The final section of theoretical part is focused on the in situ forming implants, whose carrier of active substance is biodegradable polyester. The experimental part analyzes the influence of different pH of the medium within physiologically common boundaries and also the influence of ionic force on the degree of swelling and polymer erosion. These degradation parameters have been studied on three potential polyester carriers of active substances - PLGA, M3 (terpolymer of lactic and glycolic acid with mannit) and T3 (terpolymer of lactic and glycolic acid with tripentaerythritol). Polymer bodies were kept in temperature of 37řC inside phosphate-citrate buffers with...

The thesis analyses a previously untreated and unexplored treatise entitled De modulo studendi. It is located in ms. M I 357, kept in the Research Library in Olomouc, formerly from the Carthusian monastery in Olomouc. In the first part the problem of dating the treatise and the manuscript is discussed by analyzing the physical characteristics of the manuscript and its content. It seems likely that the manuscript was written sometime in 1450-1460's. The treatise itself seems to be written after 1456. In this section is also shown, how the medical part of the treaties depends directly on a set of medical prescriptions, called Recepta ac consila medica, which precede the treatise in the manuscript. In the second part the content of each chapter of De modulo studendi is summarized and commented. The treatise provides special advices on schoolbooks at the university level as well as the general advices for successful study. An edition of the selected parts of the treatise is also included in this work.

It is also an attempt to follow how it unfolds in the work of Roland Barthes through a small set of selected texts: Writing Degree Zero, Mythologies, Elements of Semiology, L obvie et l obtus, Roland Barthes by Roland Barthes, and Camera Lucida. This research implies in handling the concept of connotation, through which Barthes defines the myth as an ultra-signification message. We here play with the hypothesis of the concept of studium, belatedly introduced in Camera Lucida, as a reformulation of the myth in the photography field, since Barthes himself sees in it the same characteristic effect of the connotative phenomenon. In such a manner, the corpus of this research is given by the author s mentioned texts; for its convenient aspect, it is also added of the repertoire of images offered by the researcher Jacqueline Guittard and her Mythologies illustrées, which recaptures and expands the edition known so far; the images of Camera Lucida are also added to it. The relevance of this research is tied to the possibility offered by Barthes oeuvre to criticize the mass communications in a historic and semiotic perspective, always paying attention to the work of the signifier / O trabalho tem por objetivo primordial apresentar o conceito barthesiano de mito , conforme definido em Mitologias. Trata-se também de acompanhar seus desdobramentos na obra de Roland Barthes por meio de um pequeno conjunto de textos selecionados: O grau zero da escritura, Mitologias, Elementos de semiologia, O óbvio e o obtuso, Roland Barthes por Roland Barthes e A câmara clara. Tal busca demanda trabalhar com o conceito de conotação, através do qual Barthes define o mito enquanto uma mensagem de ultrassignificação. Jogamos com a hipótese de que o conceito de studium, tardiamente introduzido em A câmara clara, é a reformulação do mito no campo da fotografia, já que Barthes vê aí o mesmo efeito característico do fenômeno conotativo. Assim, o corpus da pesquisa é dado pelos referidos textos do autor. Pelo caráter oportuno, este corpus é acrescido do repertório de imagens fornecido pela pesquisadora Jacqueline Guittard em seu Mitologias ilustrado, que retoma e aumenta a edição até aqui conhecida; a isto acrescentam-se ainda as imagens de A câmara clara. A relevância da pesquisa liga-se à possibilidade que a obra de Barthes nos oferece de voltar às comunicações de massa uma crítica ao mesmo tempo semiótica e histórica, sempre atenta ao trabalho do significante

Large format photography refers to the photographic practice that utilizes a large light sensitive surface to capture photographs. As of 2018, large format photography is still a subset of analog photography. The digital revolution brings us into the digital era. Manufacturers and businesses in the photography industry is forced to adapt the transition from analog to digital in order to survive and succeed in the new market. Meanwhile, photography theorists find themselves facing a new set of issues because the photographs have become immediate and immaterial. While camera manufacturers have in effect accelerated the analog-to-digital transition with their proactive business strategies and relentless marketing campaigns, higher education has become the last bastion for the analog where large format camera classes teach students the tradition of photography and how to see the world contemplatively.

Ein Studium im Ausland zu absolvieren hat unter deutschen Studierenden in den letzten Jahren stark an Popularität gewonnen. Die zunehmende Internationalisierung bietet zahlreiche Möglichkeiten für ein Auslandsstudium. Gleichwohl ergibt sich aus dem anhaltenden Globalisierungstrend die Notwendigkeit als auch die Nützlichkeit eines derartigen Aufenthaltes. Internationale und interkulturelle Begegnungen sind wesentliche Bestandteile unseres alltäglichen Handelns geworden. Die Fähigkeit, in verschiedenen kulturellen Kontexten erfolgreich agieren zu können, so genannte interkulturelle Kommunikation, erscheint wichtiger denn je. Auslandserfahrung gilt demnach als ein notwendiges Element ‚moderner’ Biografien. Studienaufenthalte außerhalb der eigenen Ländergrenzen bieten die Möglichkeit, fremde Kulturen und Menschen sowie deren Sitten und Gebräuche kennen zu lernen. Neben Faszination bedeutet das Leben in einem fremdkulturellen Umfeld jedoch nicht selten eine große Herausforderung. Demzufolge entstand auch die Idee zu dieser Arbeit aus der Auseinandersetzung mit meinen persönlichen Erfahrungen, im Ausland zu leben und zu studieren. Um einen Einblick in die Erfahrungswelten deutscher Studierender in den USA zu erhalten, wurde eine qualitative Untersuchung durchgeführt, die in der vorliegenden Arbeit ausführlich dokumentiert ist. Die empirische Basis bilden acht Textkorpora, die mit Hilfe von offenen Interviews erhoben und qualitativ ausgewertet wurden.

Universitäten treten im Zuge der demografischen Wende in einen Wettstreit um Studierende. Fasst man die Universität in diesem Sinne als Unternehmen, Studiengänge als Dienstleistungen und die Studierenden als Kundinnen und Kunden dieser Dienstleistungen auf, rückt die Sicherung und Weiterentwicklung der Qualität des gesamten Studienumfelds in den Mittelpunkt der Betrachtungen. Qualität wird hier in erster Linie als customer satisfaction verstanden, also als Zufriedenheit der Studierenden1. Darüber hinaus tragen die Rückmeldungen von Studierenden zur Weiterentwicklung der Lehrerbildung im Allgemeinen bei. Die Gesamtschau dieser Studierendeneinschätzung hilft zum einen Problembereiche des modularisierten BA-Studiums zu identifizieren und so Verbesserungspotentiale zu erkennen. Zum anderen gibt der Blick auf die positiven Aspekte des Studiums Rückmeldung zu erreichten Verbesserungen, sowie Bereichen in denen Veränderungen beibehalten oder verstärkt werden sollten. Nicht zuletzt dient dies der positiven Außendarstellung des Studiums an der Universität Leipzig.
