Theodor Storm's novelle ''Carsten Curator': An evaluation of the terms "Befreiungsdichtung" and "das Peinliche".
No full textThis thesis undertakes an analysis of two interrelated aspects of Theodor Storm's later prose writing. The Novelle Carsten Curator (1877) has been selected since this work constitutes the most significant example of both "Befreiungsdichtung" and "das Peinliche". A definition of "Befreiungsdichtung" - the artistic projection of personal experience as an act of 'self-liberation' - and the way this is revealed in a series of earlier works is the subject of the first chapter. The following three chapters offer a study of the genesis of Carsten Curator and show by an investigation into Storm's relationship with his eldest son (Chapter 2) the extent of the autobiographical content in the Novelle (Chapter 4) and Storm's awareness of its 'confessional' nature while writing it (Chapter 3). The second part of the thesis concerns itself with artistic problems which thereby arose for Storm. The creative process conditioned Storm's treatment of the thematic complex of heredity, alcoholism and paternal responsibility in Carsten Curator and brought with it a degree of realism which the author and his more sensitive critics found 'unpoetic' and thus 'offensive' (Chapter 5). This constitutes "das Peinliche", which Storm believed detracted from the 'tragic' nature of the central conflict. The following two chapters assess Carsten Curator in the light of Storm's theoretical definitions of "das Tragische" and draw the conclusion that the Novelle is a prime example of his mature tragic art. Chapter 8 discusses the implications of "das Peinliche" for a study of Storm's later Novellen (1877 - 1888), including the development of his realism, the effects of literary censorship on his later treatment of the central themes of Carsten Curator and his knowledge of Naturalist literature, showing the absence of any direct influence where these themes are concerned. The thesis concludes that Storm's continuing preoccupation with the themes of Carsten Curator after 1877 can be attributed only to their 'confessional' nature
Influence of Acidity, Water and Temperature on the Double Layer Properties of Protic Ionic Liquids for Future Fuel Cell Applications
No full textPolymer electrolyte membrane fuel cells (PEMFC) are a viable alternative to combustion engines and rechargeable batteries for automotive applications. However, the operating temperature of PEMFCs using sulfonated fluoropolymers, e.g. NAFION®, is limited below 80 °C (ambient pressure), because the proton conduction relies on the presence of water. A PEMFC operating above 100 °C would allow a much more simplified system setup for water and heat management. This requires novel non-aqueous protic electrolytes. Proton conducting ionic liquids (PIL) are promising candidates. [1,2]. However, the fuel cell relevant electrode reactions—oxygen reduction and hydrogen oxidation reaction (ORR/HOR)—are not as well understood as in aqueous electrolytes.In this study, we employed electrochemical impedance spectroscopy (EIS), cyclovoltammetry (CV), chronoamperomery (CA) and steady state current measurements to elucidate the double layer properties of the platinum electrode/PIL interface, the kinetics and possible mechanism of the ORR. Three PILs with different cation acidities with an Brønsted-acidic cation [HA+][X−] are compared, [Dema][TfO], [1-EIm][TfO] and [2-Sema][TfO].Comparing the PILs with different cation acidity strongly suggest that the first reduction step including the proton transfer to the (catalytic) active sites on the electrode is mainly determining the ORR rate. The presence of residual water, unavoidable also at fuel cell operation >100 °C, is another important parameter. H2O modifies the ordered structure of the electrochemical double layer. Its protolysis equilibrium with an acidic PIL cation results in the formation of H3O+ that serves as a proton donor in the rate determining step and thus influences the ORR kinetics. Highly acidic PIL cations serve as a proton donor as well, particularly at low H2O concentrations, whereas the role of H3O+ as proton donor in the ORR becomes more prominent at higher water concentrations [3]. In low acidic PILs, H3O+ is the predominant proton donor and the ORR rate is significantly smaller resulting in considerably higher overpotentials. Thus, the onset potential of the ORR in a PIL based fuel cell will depend on both the concentration of residual water and the PIL cation acidity.Plots of the potential-dependent data from EIS measurements in the complex capacitance plane (CCP) show that at least two differential double layer capacitances are present, depending on the cell potential U (vs. RHE), water concentration c(H2O) and temperature T. The double layer properties of the highly acidic [2-Sema][TfO] are significantly different compared to the less acidic PILs [1-EIm][TfO] and [Dema][TfO]. The potential dependent capacitance curves were discussed by taking a mean field model, the presence of water and short range correlations of ions into account. [4, 5] The combined electrochemical kinetics and double layer measurements provide a deeper insight into the double layer structure at the Pt electrode/PIL interface to reveal the rate limiting parameters of the ORR and its mechanism.[1] K.

Analysis of Styrian parish bulletins
No full textDie vorliegende Diplomarbeit untersucht vier steirische Pfarrblätter unter der Perspektive der Delta-Milieu-Studie. Der erste Teil der Arbeit stellt die relevanten Theorien der Milieueinteilung der Gesellschaft, insbesondere der von Carsten Wippermann durchgeführten DELTA-Milieustudie vor. In einem nächsten Schritt wird versucht eine Begriffseingrenzung des Mediums Pfarrblatt vorzunehmen und die Bedeutung des Pfarrblattes in der kirchlichen Öffentlichkeitsarbeit diskutiert.Basierend auf diesem Konzept folgt dann im zweiten Teil eine Analyse von ausgewählten steirischen Pfarrblättern. Nachfolgend soll die Forschungsfrage beantwortet werden, welche Milieus von den jeweiligen Pfarrblättern angesprochen werden. Dabei wird nicht nur die Ebene der LeserInnen beleuchtet, sondern auch die derjenigen, die ein Pfarrblatt gestalten und produzieren. Mit Hilfe von Interviews soll geklärt werden, ob ein gewisses Milieubewusstsein bei den sogenannten Pfarrblatt-MacherInnen vorhanden ist. Zuvor werden noch Methodik, Auswahl der ExpertInnen und Leitfadenkategorien erläutert. Danach folgen eine Zusammenschau der Interviewaussagen und ein daraus resultierendes Fazit.This thesis looks into four Styrian parish bulletins under the aspect of the DELTA-Milieu-study. The first part of this work describes the relevant theories of divisions of society milieus, especially the from Carsten Wippermann developed DELTA-study. Following by a definition of the term parish bulletin and a discussion of this media in the church public relations work.Based on the concept of the DELTA-Milieu-study there will be an analysis of the selected styrian parish bulletins in the second part of this work. Followed by the answering of the research question , which milieus are directed at by the respective parish bulletin. But not only the level of readers is taken in account, also the level of producers and publishers. The Question if the makers of the parish bulletins are aware of the different milieus will be answered with assistance of interviews. Finally those interviews will be combined and the author will take stock of these interviews and suggest possible future acts.eingereicht von Tina Sophie SchmidAbweichender Titel laut Übersetzung der Verfasserin/des VerfassersGraz, Univ., Dipl.-Arb., 201
