In the present contribution, the utilization of steel-mill gases for an industrial methanol synthesis process is described. The focus of this work is on the influence of syngas compositions derived from steel-mill gases on an industrial Cu/ZnO/Al2O3 catalyst. Elevated CO2 and H2O concentrations seem to have an irreversible impact on the activity of the catalyst. In order to obtain realistic gas composition for the catalyst tests, a process simulation of the methanol synthesis was conducted. The calculated gas compositions at the reactor inlet were applied in a practical test in order to evaluate the catalyst stability under steel mill gas conditions. No noticeable deactivation was observed.
Rituals, such as gazing at faces, are common in body dysmorphic disorder (BDD) and appear in cognitive-behavioral models as a maintaining factor. Rituals are also common in obsessive-compulsive disorder (OCD). In contrast to OCD, the proposed associations between rituals and intrusive thoughts/appearance preoccupation have not been empirically investigated for BDD. We examined if the assumed effect of gazing rituals on attractiveness ratings exists and if it is associated with dissociation. In an experiment, we asked N = 65 non-clinical females to focus on the nose of a photographed face at pre- and post-test. In between, participants gazed at the nose of either the same (relevant gazing) or another face (irrelevant gazing). We found increasing dissociation after gazing in both conditions and a differentially stronger decrease of attractiveness ratings in the relevant gazing condition. Our findings support the hypothesized effect of gazing rituals on attractiveness evaluation in cognitive-behavioral models for BDD.
Der Beitrag stellt am Beispiel von studentischen Projekt- und Praxisarbeiten aus den bibliothekswissenschaftlichen Studiengängen der TH Köln Möglichkeiten der Erstellung von E-Learning-Angeboten vor, die sich in kurzer Zeit und ohne finanzielles Budget realisieren lassen. Der Fokus liegt dabei auf unkonventionellen Darstellungsformen wie bspw. Comic-artigen Animationsfilmen oder der Präsentation bibliothekarischer Inhalte nach dem Modell von „Sommers Weltliteratur“. Der Beitrag möchte Bibliotheken dazu anregen, im Kontext des E-Learning mit neuen Formaten zu experimentieren, die dazu beitragen können, die Attraktivität der bibliothekarischen Angebote zu erhöhen und die sich gleichzeitig mit geringem zeitlichem und finanziellem Aufwand realisieren lassen.
