Spiel und Geschichte
(transcript Verlag, 2010)
Es stellt sich die Frage, worin der Unterschied zwischen Spiel und Geschichte besteht. Aktuell ist diese Frage, weil neuere Forschung die narrativen Züge des Computerspiels herausarbeitet, ohne die Differenz zwischen Spiel und Geschichte hinreichend geklärt zu haben. Besitzen nur Computerspiele narrative Züge? Und wenn ja, weshalb? Weshalb stellt sich die Frage nach der Narrativität von Spielen erst mit dem Computerspiel? Aktuell ist diese Frage auch, weil das Paradigma Computerspiel gängigen Thesen heutiger Medientheorie ...

SSPIM: a beam shaping toolbox for structured selective plane illumination microscopy
(2018-07-03)
Selective plane illumination microscopy (SPIM) represents a preferred method in dynamic tissue imaging, because it combines high spatiotemporal resolution with low phototoxicity. The OpenSPIM system was developed to provide an accessible and flexible microscope set-up for non-specialist users. Here, we report Structured SPIM (SSPIM), which offers an open-source, user-friendly and compact toolbox for beam shaping to be applied within the OpenSPIM platform. SSPIM is able to generate digital patterns for a wide range ...

Use of organic wastes of Agave processing for bioenergy production
(2018)
Der organische Reststoff, welcher bei der Verarbeitung der Agave S. anfällt (Mezcal-Schlempe), ist aufgrund der hohen Anteile an organischer Substanz, anorganischen Salzen und anderer Inhaltstoffe ein umweltschädlicher Rückstand, der nicht ohne Vorbehandlung in Gewässer oder Böden gelangen darf, ggf. aber für die Bioenergieerzeugung genutzt werden könnte. Im Rahmen dieser Arbeit wurde daher unter Laborbedingungen die Eignung dafür durch drei Versuche zur anaeroben Vergärung und zwei zu mikrobiellen Brennstoffzellen ...

Direct evidence for radiative charge transfer after inner-shell excitation and ionization of large clusters
(2018-01-16)
We directly observe radiative charge transfer (RCT) in Ne clusters by dispersed vacuum-ultraviolet photon detection. The doubly ionized Ne^2+ – Ne_n-1 initial states of RCT are populated after resonant 1s–3p photoexcitation or 1s photoionization of Ne_n clusters with {n} \approx 2800. These states relax further producing Ne^+ – Ne^+ – Ne_n-2 final states, and the RCT photon is emitted. Ab initio calculations assign the observed RCT signal to the Ne^2+(2p^-2 [^1D]) - Ne_n-1 initial state, while transitions from other ...

Circular Dichroism in Fluorescence Emission Following the C 1s→π* Excitation and Resonant Auger Decay of Carbon Monoxide
(2018-06-26)
Dichroism in angle-resolved spectra of circularly polarized fluorescence from freely-rotating CO molecules was studied experimentally and theoretically. For this purpose, carbon monoxide in the gas phase was exposed to circularly polarized soft X-ray synchrotron radiation. The photon energy was tuned across the C 1s→π* resonant excitation, which decayed via the participator Auger transition into the CO+ A 2Π state. The dichroic parameter β1 of the subsequent CO+ (A 2Π → X 2Σ+) visible fluorescence was measured by ...

Efficient Spatial and Temporal Modelling of Material Temperatures within Self-reinforced Polypropylene Sheets during IR Radiation
(2013-07-20)
Polymer composites of self-reinforced fibres and a matrix composed of the same plastic material display an outstanding mechanical performance and an excellent recyclability. Hence, these materials are suitable for many practical applications. One disadvantage, however, is the narrow processing window that is caused by a strong pressure and temperature sensitivity of the self-reinforced fibres. In this paper, an approach to efficiently model the spatial and temporal temperature evolution is presented. Advanced empirical ...

Kategorien diskurstraditionellen Wissens als Grundlage einer kulturbezogenen Sprachwissenschaft
(V&R UnipressBonn University Press, 2015)
Das in der Romanistik entwickelte Konzept der Diskurstradition als kultureller Leitfaden kommunikativ angemessener Textgestaltung ist ein zentraler Grundbegriff für eine kulturbezogene Sprachwissenschaft. Ein Charakteristikum dieses Konzepts ist seine große Spannweite. So können unter dem Konzept der Diskurstradition ganz unterschiedliche kulturelle Muster des Sprechens und Schreibens subsumiert werden: Zum diskurstraditionellen Wissen zählen kommunikative Gewohnheiten wie Begrüßungen oder Gesprächseröffnungen, doch ...

Water Quality in Surface Water: A Preliminary Assessment of Heavy Metal Contamination of the Mashavera River, Georgia
(2018-03-23)
Water quality contamination by heavy metal pollution has severe effects on public health. In the Mashavera River Basin, an important agricultural area for the national food system in Georgia (e.g., vegetable, dairy and wine production), water contamination has multiple influences on the regional and country-wide health. With new industrial activities in the region, sediment extraction, and discharge of untreated wastewater into the river, its tributaries and irrigation canals, a comprehensive study of water quality ...

The Positive Facet of Self-compassion Predicts Self-reported Use of and Attitudes toward Desirable Difficulties in Learning
(2017-08-09)
Previous research found that introducing difficulties and challenges during learning has desirable outcomes. With the present work, we investigated the question how the use of and the attitudes toward such learning strategies (so-called desirable difficulties) are related to self-compassion, a concept that describes the tendency to be understanding and kind to oneself when confronted with negative experiences. Evidence suggests self-compassion to be linked to less fear of failing, and further to higher control beliefs ...
