39. Ägyptologische Übersetzung - ein historisch bezogener Einblick in Übersetzungsprozesse einer ausgestorbenen Sprache

Author

Cabaj, Joanna Marianna

Abstract

Die vorliegende Masterarbeit widmet sich ägyptologischer Übersetzungsprozesse. Die Übersetzungsprozesse altägyptischer Texte wurden von unterschiedlichen historischen Umständen geprägt und oft auch von ihnen gleichzeitig beeinträchtigt. Die einzelnen Übersetzungen zeugen von den historischen Prozessen, die zur Formung der Ägyptologie als akademische Disziplin beitrugen und damit auch die Bezugsrahmen für translatorische Vorgänge boten. Sowohl soziokulturelle Phänomene wie Orientalismus und Kolonialismus als auch der kontinuierliche Paradigmenwechsel in der Übersetzungspraxis hinterliessen ihre deutlichen Spuren in einzelnen Zieltexten, die sich beschreiben und analysieren lassen. Die Analyse der Übersetzungsproben, die in der vorliegenden Arbeit durchgeführt wurde, sollte jedoch nicht jede charakteristische Eigenschaft der ägyptologischen Übersetzungsprozesse identifizieren und analysieren. Dennoch sollen die ausgewählten Fragmente veranschaulichen, in welchen Bereichen und Aspekten des translatorischen Vorgangs anspruchsvolle Besonderheiten vorkommen. Mithilfe eines diachronischen Vergleichs der einzelnen Übersetzungsproben lässt sich auch die Übersetzungsgeschichte einzelner Literaturwerke verfolgen, in deren Rahmen auch der Paradigmenwechsel zu beobachten ist., This master’s thesis focuses on egyptological translation processes. The translation processes of the Old Egyptian texts have been influenced by different historical phenomena that shaped them but oftentimes deformed them as well. The individual translations bear testimony to historical processes that shaped egyptology as an academic discipline it is today and provided referential frames for the translatological activities. Not only the sociocultural phenomena such as orientalism and colonialism but the continuous paradigm shift in translation practice left their traces in the individual target texts, which can be described and analysed. The analysis of the chosen translation samples, that can be found in this thesis, does not name and analyse each and every characteristic trait of egyptological translation processes. Nevertheless, it should allow to identify the areas and aspects of particular interest, where these challenging distinctive features stem from. It is also possible to follow the translation history of the individual literary works with help of diachronic comparison, which in turn illustrates the paradigm shift of the translation practice in question.

44. Conducting Polymers as Elements of Miniature Biocompatible Sensor

Author

Technology & Engineering / Electronics
Abstract

Conducting polymers (CPs), the so-called “fourth generation of polymeric materials”, can solve essential problems in biosensing technologies due to their unique material properties and implementation in innovative device systems. CPs have excellent biocompatibility. They can provide advantageous interfaces for bioelectrodes owing to their hybrid conducting mechanics, combining both electron and ionic charge carriers. Many (i.e. glucose) biosensors use immobilized enzymes to form a selective layer on CP structure. Miniaturization of sensors is a new requirement. Mini sensors are portable and wearable with low utilization of sample and cost-effective technology of production.

Abstract

The results presented in this paper show how the optical properties and colloidal stability of quantum dots (QDs) vary depending on pH conditions. For this investigation, as-synthesized hydrophobic CdSe/CdS QDs were transferred to an aqueous medium by surface modification with 3-mercaptopropionic acid. The ligand exchange procedure was applied under three different pH conditions: acidic, neutral and alkaline, to obtain three kinds of hydrophilic QDs dispersed in phosphate buffer. The efficiency of the functionalization of QDs was estimated based on the changes in ABS and the highest value was obtained under acidic conditions (45%). The efficiency of photoluminescence (PL) was also best preserved under these conditions, although it was 30 times less than the PL of hydrophobic QDs. Then, all three kinds of hydrophilic QDs were dispersed in solutions with a wide range of pH (2–12) and investigated by absorbance and PL measurements. The results show that QDs subjected to a ligand exchange procedure are characterized by intensive PL at the selected pH values, which correspond to pKa of the ligand. This phenomenon is independent of the pH at which the ligand exchange procedure is conducted. Moreover, it was found that the PL intensity is preserved during the experiment for QDs functionalized under neutral conditions, whereas it decreases for acidic and increases for alkaline conditions.

Abstract

An useful electrochemical sensing approach was developed for norepinephrine (NE) detection based on semiconducting polymer (9-nonyl-2,7-di(selenophen-2-yl)- 9H-carbazole) and laccase modified platinum electrode (Pt). The miniature Pt biosensor was designed and constructed via the immobilization of laccase in an electroactive layer of the electrode coated with thin polymeric film. This sensing arrangement utilized the catalytic oxidation of NE to norepinephrine quinone. The detection process was based on the oxidation of catecholamine in the presence of enzyme -- laccase. With the optimized conditions, the analytical performance demonstrated selectivity in a wide linear range (0.1-200x10-6 M) with a detection limit of 240 nM and a quantification limit of 365 nM. Moreover, the method was successfully applied for selective NE determination in the presence of interfering substances. [ABSTRACT FROM AUTHOR]
