The production of lightweight materials is usually associated with an increase in energy demand, so the environmental impacts of lightweight structures need to be assessed holistically using a life cycle assessment. To estimate the life cycle environmental impacts of a product in its developmental stage, for example, by life cycle engineering, future changes in relevant influencing factors must be considered. Prospective life cycle assessment provides methods for integrating future scenarios into life cycle assessment studies. However, approaches for integrating prospective life cycle assessment into product development are limited. The objective of this work is to provide the methodological foundation for integrating future scenarios of relevant influencing factors in the development of lightweight structures. The applicability of the novel methodology is demonstrated by a case study of a structural component in a steel, aluminium, and hybrid design. The results show that appropriate decarbonisation measures can reduce the life cycle greenhouse gas emissions by up to 95 percent until 2050. We also found that shifts in the environmentally optimal design are possible in future scenarios. Therefore, the methodology and data provided contribute to improved decision-making in product development.","lang":"eng"}],"user_id":"44763","keyword":["Life Cycle Engineering","Life Cycle Assessment","Lightweight Design","Prospective LCA","Future-oriented LCA","Energy System","Material production","Sustainable production"],"publication":"Energies","author":[{"id":"44763","last_name":"Ostermann","full_name":"Ostermann, Moritz","orcid":"https://orcid.org/0000-0003-1146-0443","first_name":"Moritz"},{"last_name":"Grenz","full_name":"Grenz, Julian","first_name":"Julian"},{"last_name":"Triebus","id":"66036","first_name":"Marcel","full_name":"Triebus, Marcel"},{"last_name":"Cerdas","full_name":"Cerdas, Felipe","first_name":"Felipe"},{"full_name":"Marten, Thorsten","first_name":"Thorsten","id":"338","last_name":"Marten"},{"first_name":"Thomas","full_name":"Tröster, Thomas","last_name":"Tröster","id":"553"},{"last_name":"Herrmann","full_name":"Herrmann, Christoph","first_name":"Christoph"}],"quality_controlled":"1","publisher":"MDPI AG","volume":16,"date_created":"2023-04-13T09:11:33Z","status":"public","intvolume":" 16","_id":"43464","article_number":"3371","issue":"8","main_file_link":[{"url":"https://www.mdpi.com/1996-1073/16/8/3371","open_access":"1"}],"year":"2023","citation":{"ieee":"M.

This existing research suggests that SA effects on language skills tend to be volatile, while the impact on various aspects of learners’ personal, academic, and professional development may be longer-lasting. Yet, learner perspectives on the dynamics and durability of such effects, in particular in the context of short-term SA programs, remain largely unexplored. This study hence investigates the near-term impact of short-term SA programs as experienced by students within the first months and years following their sojourns. A qualitative case-study design is employed to examine the accounts of four American students of German, who studied abroad in Austria for four weeks and were interviewed repeatedly over a period of up to 40 months after their sojourns. The results suggest that, from the students’ perspective, many effects deteriorate in the near term, although the overall sojourn experience still appears influential.\r\nAbstract in German\r\nNur wenige Forschungsvorhaben haben sich bislang den mittel- bis langfristigen Auswirkungen studentischer Auslandsaufenthalte gewidmet; die bisherige Datenlage deutet jedoch darauf hin, dass die Auswirkungen auf sprachliche Kompetenzen eher unbeständig sind, wohingegen die persönliche, studiums- und berufsbezogene Entwicklung der Lernenden länger von einem Auslandsaufenthalt beeinflusst wird. Die Dynamik und Beständigkeit derartiger Auswirkungen wurden jedoch kaum mit Blick auf kurze Auslandsaufenthalte (≤ acht Wochen) sowie aus der Perspektive der Studierenden erforscht, was die vorliegende Studie insbesondere hinsichtlich mittelfristiger Effekte fokussiert. Mittels eines qualitativen Fallstudiendesigns werden die Interviewdaten vier amerikanischer Deutschlernender untersucht, die sich vier Wochen in Österreich aufhielten und in einem Zeitraum von bis zu 40 Monaten nach ihrem Aufenthalt wiederholt befragt wurden. Die Ergebnisse zeigen, dass viele Auswirkungen eines solchen Aufenthalts aus studentischer Perspektive mittelfristig verblassen, auch wenn der Auslandsaufenthalt im Gesamten weiterhin als einflussreiche Erfahrung wahrgenommen wird.","lang":"eng"}],"user_id":"71540","author":[{"id":"71540","last_name":"Müller","full_name":"Müller, Mareike","orcid":"0000-0002-4940-0297","first_name":"Mareike"}],"publisher":"The Forum on Education Abroad","publication":"Frontiers: The Interdisciplinary Journal of Study Abroad","status":"public","date_created":"2023-04-19T07:21:28Z","volume":35},{"language":[{"iso":"ger"}],"doi":"10.1002/cite.202200243","oa":"1","date_updated":"2023-04-27T07:26:18Z","publication_status":"published","department":[{"_id":"9"},{"_id":"145"}],"title":"Untersuchung überlagerter Effekte von Druckverlust und Totvolumen durch Rekuperation am isobaren Expansionsmotor","citation":{"apa":"Mügge, N., Kronberg, A., Glushenkov, M., & Kenig, E.

Typically, only the minimum distance between the measuring surfaces is used for further calculation, implying that no flow occurs between the structural elements. But this assumption is misleading, and a gap correction is necessary. To determine the radius correction $$\\Delta r$$\r\n \r\n Δ\r\n r\r\n \r\n for specific geometries, we conducted investigations on three Newtonian fluids (two silicon oils and one suspension considered to be Newtonian in the relevant shear rate range). The results show that $$\\Delta r$$\r\n \r\n Δ\r\n r\r\n \r\n is not only shear- and material-independent, but geometry-dependent, providing a Newtonian flow behaviour in a similar viscosity range. Therefore, a correction value can be determined with only minute deviations in different Newtonian fluids. As the conducted laboratory measurements are very time-consuming and expensive, a CFD-approach with only very small deviations was additionally developed and compared for validation purposes. Therefore, simulation is an effective and resource-efficient alternative to the presented laboratory measurements to determine $$\\Delta r$$\r\n \r\n Δ\r\n r\r\n \r\n for the correction of structured coaxial geometries even for non-Newtonian fluids in the future."}],"status":"public","date_created":"2023-01-17T08:04:24Z","quality_controlled":"1","author":[{"id":"38243","last_name":"Josch","full_name":"Josch, Sebastian","first_name":"Sebastian"},{"id":"3959","last_name":"Jesinghausen","orcid":"https://orcid.org/0000-0003-2611-5298","full_name":"Jesinghausen, Steffen","first_name":"Steffen"},{"id":"69828","last_name":"Dechert","full_name":"Dechert, Christopher","first_name":"Christopher"},{"last_name":"Schmid","id":"464","first_name":"Hans-Joachim","orcid":"000-0001-8590-1921","full_name":"Schmid, Hans-Joachim"}],"publisher":"Springer Science and Business Media LLC","keyword":["rheology","rheometry","suspension","coaxial","correction"],"publication":"Rheologica Acta","_id":"36983","citation":{"chicago":"Josch, Sebastian, Steffen Jesinghausen, Christopher Dechert, and Hans-Joachim Schmid. “Experimental and Simulative Determination and Correction of the Effective Gap Extension in Structured Coaxial Measuring Systems.” Rheologica Acta, 2023. https://doi.org/10.1007/s00397-023-01383-2.","ama":"Josch S, Jesinghausen S, Dechert C, Schmid H-J.
