Grenzen der Übersetzbarkeit am Beispiel der romantischen Poesie

Das Ziel der vorliegenden Untersuchung besteht nicht darin, verschiedene Varianten der Übersetzungen von Novalis’ Lyrik ausführlich zu analysieren und zu vergleichen (die russische Übersetzung von Vladimir Mikuševič wurde deshalb gewählt, weil sie einfach als die „neueste“ gilt) oder über theoretische Fragen der Übersetzung zu diskutieren und „bessere“ Varianten vorzuschlagen. Die Aufgabe der Arbeit besteht vielmehr darin, an einzelnen konkreten Beispielen aus den Hymnen an die Nacht und den Geistlichen Liedern zu veranschaulichen, dass bei einer Übersetzung unvermeidlich die Semantik von vielen Wörtern, die im Deutschen nicht nur eine bestimmte Bedeutung haben, sondern auch den Leser auf ein bestimmtes Feld von kulturellen Parallelen und Assoziationen führen, verlorengeht. Es geht also um solche Ausdrücke, die selbst im Deutschen eines Kommentares, einer Erläuterung bedürfen

Theory of Thermal Remagnetization of Permanent Magnets

A self-consistent mean-field theory explaining the thermal remagnetization (TR) of polycrystalline permanent magnets is given. The influence of the environment of a grain is treated by an inclusion approximation, relating the field inside the grain to the local field outside by means of an internal demagnetization factor $n$. For the switching fields and the fluctuations of the local fields around the mean field Gaussian distributions of widths \sigmas and \sigmaf resp. are assumed. The isothermal hysteresis curve, the recoil curves, and the TR in dependence on the model parameters $n$, \sigmas, and \sigmaf are calculated. Furthermore, the influence of the initial temperature and the strong dependence of the TR on the demagnetization factor of the sample are studied, and it is shown that for reasonable parameter sets TR effects up to 100 % are possible. The theoretical results correspond well with the experimental situation.Comment: 28 pages, 9 figures, Latex2e, accepted for publication in JMM

Understanding the electromagnetic interaction of metal organic framework reactants in aqueous solution at microwave frequencies

Preparation of metal organic frameworks (MOFs) via microwave heating is becoming increasingly popular due to reduced reaction times and enhanced control of MOF particle size. However, there is little understanding about the detailed interaction of the electric field portion of the wave with reactants during the synthesis of MOFs. In order to overcome this lack of fundamental understanding, information about the dielectric properties of the reactants is required. In this work the dielectric constants (ε′) and loss factors (ε′′) of benzene-1,4-dicarboxylic acid (H2BDC; also known as terephthalic acid) and a number of M(III) (M = metal) salts dissolved in deionized water were measured as a function of frequency, temperature and concentration and with varying anions and cations. Dielectric data confirm the aqueous M(III) salts to be strong microwave absorbers, particularly at 915 MHz. M(III) salts with mono-anionic ligands (for example chlorides and nitrates) exhibit higher losses than di-anionic salts (sulfates) demonstrating that the former are heated more effectively in an applied microwave field. Of the M(III) salts containing either singly- or doubly-charged anions, those containing Fe(III) have the highest loss indicating that they will heat more efficiently than other M(III) salts such as Cr(III) and Al(III). Interestingly, H2BDC exhibits little interaction with the electric field at microwave frequencies
