The research project »text sound«: mixed-methods-analysis of lyric poetry in text and tonal sound (funded by the Federal Ministry for Education and Research, BMBF) aims to undertake a systematic and diachronic investigation of the relationship between literary texts, especially lyric poetry from the Romantic period, and their phonetic realisation in recitations or musical performances. Ideas of orality, sound and voice, which are particularly associated with poetry, are investigated empirically and also theorised in the line with modern approaches to the analysis of lyric poetry. Of particular importance is the experimental approach of speech synthesis, i.e. using computers to artificially produce a human sounding voice; this approach makes it possible to explore an ideal-typical realisation of the text and to test the aesthetic peculiarity of human realisations.

Evolutionary change following gene duplication can lead to functionally divergent paralogous proteins. If comprising identical subunits their random assortment would also form potentially detrimental heteromeric proteins. In Arabidopsis, the ARF GTPase guanine-nucleotide exchange factor GNOM is essential for polar recycling of auxin-efflux transporter PIN1 from endosomes to the basal plasma membrane whereas its paralog GNL1 mediates retrograde Golgi-endoplasmic reticulum traffic. Here we show that both GNOM and GNL1 form homodimers but no heterodimers. To assess the biological significance of this, we generated transgenic plants expressing engineered heterodimer-compatible GNOM variants. Those plants showed developmental defects such as the failure to produce lateral roots. To identify mechanisms underlying heterodimer prevention, we analyzed interactions of the N-terminal dimerization and cyclophilin-binding (DCB) domain. Each DCB domain interacted with the complementary fragment (ΔDCB) both of their own and of the paralogous protein. However, only DCB

The laminar burning velocity belongs to the fundamental combustion properties of fuels being a measure for their heat release, flame length, as well as reactivity and combustion stability, and thus, may impact the design of burners and combustion chambers. Also, these experimental data are needed for the validation and optimization within the construction and development of detailed chemical kinetic reaction mechanisms. Within this study, an overview of the different applications of fuel characterization regarding the specific area of interest (road transport, aviation, and aerospace) will be given. Depending on the application, effects of different molecular characteristics on the laminar burning velocity are evaluated: the presence of oxygen atoms and the grade of branching in a specific fuel molecule as well as the difference in the type of a chemical bond, here, single and double bonds. Examples of alternative fuels being discussed in the present study are: (I) oxymethylene ether (OMEn) in the field of road transport; (II) a paraffinic Alcohol-to-Jet fuel as sustainable aviation fuel; and (III) mixtures of ethane or ethene with nitrous oxide as green propellants for rocket propulsion applications.

Cognitive approaches are particularly appealing when it comes to phenomena that can be adequately described only when their mental processing is taken into account. The phenomenon of irony is one of them. While there has been a plethora of semantic and structural analytic approaches in literary studies and linguistics that have focused on irony, the question is to what extent irony is already inherent in the texts themselves, to what extent it is only recognizable from contexts, and whether we recognize irony as such equally at all.In this article, we combine approaches from literary studies, cognitive psychology, and psycholinguistics in a corpus-based study. We ask whether irony is recognizable from certain textual features, such as genre or style. To determine this, we undertook a questionnaire study that indeed supports the conclusion that it is. It is the goal of the article to stimulate further contributions of this kind in order to explore the potential of a cognitive approach for the processing of irony in literary texts, providing a sound basis for future neuro-aesthetic investigations.

«KAPUTT-SCH» und «KAPPUCI-NO» mit drei Ausrufezeichen notiert Rio Reiser ganz oben auf den ersten Seiten einer Arbeitskladde für das Theaterstück Märzstürme aus dem Jahr 1981.1 Streng poetologisch handelt es sich um Ein-Wort-Verse, die unter einander stehen, gefolgt von einer dreifachen Exklamation. Hinter den rebellischen Tönen versteckten sich bei Ralph Christian Möbius, der seinen Künstlernamen aus Karl Philipp Moritz’ Anton Reiser herleitete, literarische Ambitionen. Der Punk als bundesrepublikanischer Bildungsroman: Seine Ein-Wort-Verse reichert Rio Reiser durch ein Datum an, das die Versordnung zu sprengen scheint: «März Mars [Bringt verbrauchte Energie sofort zurück!!!] MARSCH ARSCH / 13 / NEIN / 9 / ZEN ?ZINN?

Mixtures of hydrocarbons and nitrous oxide are known as green propellants and could replace the highly toxic hydrazine and hydrazine derivatives as rocket fuel, since they are non-toxic and easier to handle, but still have a high specific impulse. Possible hydrocarbon candidates are ethane or ethene. To check the applicability of the two reaction systems, C2H6/N2O and C2H4/N2O, experiments are a prerequisite for accurate predictions under various conditions that are of great importance for the design of safe and reliable thrusters. Therefore, experimental literature data obtained from ignition delay times and laminar burning velocities were used to validate and optimize a new reaction mechanism, which is designed for C0–C3 and nitrogen oxides formation. To achieve a better predictive power of the detailed mechanism, the Arrhenius parameters of three reactions were adjusted: N2O + H ⇌ N2 + OH, N2O (+ M) ⇌ N2 + O (+ M), and NH + NO ⇌ N2O + H. A good agreement was achieved between simulation and experiment for ignition delay times at various pressures and equivalence ratios in a broad temperature range before and after the mechanism optimization. However, the laminar burning velocities in the whole measured range of the equivalence ratio for all pressures and dilutions showed a significant improvement after the optimization.

Further developed methods based on an indenter penetration into a material allow generalised quantitative statements on the composition, the depth-dependent mechanical properties and the delamination behaviour of multilayer polymer films, which is demonstrated on gelatine-coated polyethylene terephthalate and polyethylene films. These highly sensitive polymer testing methods, include the recording microindentation test and the recording adhesion test, describe the material behaviour multi-parametrically and are fast (raw data acquisition within several minutes) and relatively simple, requiring a minimum 1 gram sample depending on the film thickness. Based on the Vickers hardness under load approach, the hardness–depth diagrams calculated from the recording microindentation test provide information about the structure, the thickness and the coating hardness and the substrates. The tangential load vs. tangential path length diagrams from recording adhesion test can detect different scratch processes such as continuous scratching or non-continuous stick-slip layer delamination. Furthermore, they form the basis to quantitatively analyze adhesion, i.e. to determine the critical tangential load and the critical tangential delamination work. Both are highly dependent on the substrate type and treatment.

Oxymethylene ethers (OMEn, n = 1–5) are a promising class of synthetic fuels that have the potential to be used as additives or substitutes to diesel in compression ignition engines. A comprehensive understanding of their combustion properties is required for their safe and efficient utilization. In this study, the results of a combined experimental and modeling work on oxidation of OME2 are reported: (i) Ignition delay time measurements of stoichiometric OME2/synthetic air mixtures diluted 1:5 with nitrogen using the shock tube method at pressures of 1, 4, and 16 bar, and (ii) laminar flame speeds of OME2/air mixtures using the cone angle method at atmospheric and elevated pressures of 3 and 6 bar. The experimental data sets obtained have been used for validation of three detailed reaction mechanisms of OME2 obtained from literature. The results of ignition delay time measurements showed that ignition of OME2 is characterized by pre-ignition activity at the low temperature side of the measurements regardless of the pressure. Regarding the performance of the different reaction mechanisms, the model from Cai et al. (2020, “Auto-Ignition of Oxymethylene Ethers (OMEn, n = 2–4) as Promising Synthetic e-Fuels From Renewable Electricity: Shock Tube Experiments and Automatic Mechanism Generation,” Fuel, 264, p. 116711) best predicted the temperature and pressure dependence of ignition delay times. For laminar flame speeds, the experimental data were well matched by the mechanism from Ren et al. (2019) at p = 1, 3, and 6 bar and for all equivalence ratios considered. From sensitivity analyses calculations, it was observed that chain reactions involving small radicals, i.e., H, O, OH, HO2, and CH3 control the oxidation of OME2. The comparison of the results of this work and our previous work (Ngugi et al. (2021)) on OME1 show that these two fuels have similar oxidation pathways. The results obtained in this work will contribute to a better understanding of the combustion of oxymethylene ethers, and thus, to the design and optimization of burners and engines as well.

Functionally divergent paralogs of homomeric proteins do not form potentially deleterious heteromers, which requires distinction between self and non-self (Hochberg et al., 2018; Marchant et al, 2019; Marsh and Teichmann, 2015). In Arabidopsis, two ARF guanine-nucleotide exchange factors (ARF-GEFs) related to mammalian GBF1, named GNOM and GNL1, can mediate coatomer complex (COPI)-coated vesicle formation in retrograde Golgi-endoplasmic reticulum (ER) traffic (Geldner et al., 2003; Richter et al., 2007; Teh and Moore, 2007). Unlike GNL1, however, GNOM is also required for polar recycling of endocytosed auxin efflux regulator PIN1 from endosomes to the plasma membrane. Here we show that these paralogues form homodimers constitutively but no heterodimers. We also address why and how GNOM and GNL1 might be kept separate. These paralogues share a common domain organisation and each N-terminal dimerisation (DCB) domain can interact with the complementary fragment (ΔDCB) of its own and the other protein. However, unlike self-interacting DCBGNOM (Grebe et al., 2000; Anders et al., 2008), DCBGNL1 did not interact with itself nor DCBGNOM. DCBGNOM removal or replacement with DCBGNL1, but not disruption of cysteine bridges that stabilise DCB-DCB interaction, resulted in GNOM-GNL1 heterodimers which impaired developmental processes such as lateral root formation. We propose precocious self-interaction of the DCBGNOM domain as a mechanism to preclude formation of fitness-reducing GNOM-GNL1 heterodimers.

Es ist notwendig, ein Umdenken im Bereich der Bildung zu erreichen - nicht zuletzt aufgrund der permanenten und schnellen Veränderungen, die durch Technologie möglich geworden sind. Die Digitalisierung ist dabei nur ein Teilstück, welches die Anpassungen zum einen begünstigt, zum anderen aber auch erfordert. Wissen ist jederzeit abrufbar. Zu jedem Thema findet man Informationen im Internet. Deshalb ist es zum einen wichtig, Kompetenzen zu entwickeln im Umgang mit der Vielfalt der Daten, aber auch zu erkennen, dass das reine Lehren von Wissen nicht mehr zeitgemäß ist und unsere Kinder und Jugendlichen nicht auf das vorbereitet, womit sie in ihrem Arbeitsleben konfrontiert sein werden. Die Erlangung von Kompetenzen wie Kommunikation, Kreativität, kritisches Denken und Kollaboration (4 K) rückt in den Vordergrund und löst reinen Wissenserwerb ab. Wie können wir nun mit Hilfe von Tools und Methoden ein neues Zeitalter der Bildung zumindest einmal einläuten? Wie können wir erreichen, dass Digitalität als Unterstützung und nicht als in der Pandemie notwendiges aber vorübergehendes Übel betrachtet wird? Welche Ideen haben wir für hybride Lernsettings entwickelt? Wir haben seit März 2020 sehr viel lernen dürfen und einiges ausprobiert und möchten unsere Learnings im folgenden Bericht teilen.

Modified UNIFAC (Dortmund) parameters for the interactions of the amino group at cycloaliphatic hydrocarbon with the hydroxyl group or the methanol group were determined by means of literature and our own experimental data. The vapor–liquid equilibria of the three binary systems cyclohexylamine + 2-butanol, cyclohexylamine + 2-methyl-2-butanol, and cyclohexylamine + 1-hexanol were measured isothermally with the dynamic method. The predictions of phase equilibrium data using the new parameter set for the amino group at cycloaliphatic hydrocarbon are compared to the predictions using the amino group at aliphatic hydrocarbon. The improvement of the description of experimental data is shown for binary and ternary systems.
