Published: December 2024

ABSTRACTThe topic of sustainability is currently not only omnipresent in research and politics but is also gaining significant importance in the industry. Different customer groups are increasingly attaching importance to sustainable products and adapting their purchasing behaviour accordingly.One important field of action for achieving ecological sustainability is the circular economy. Circular economy describes a cycle-based model of production and consumption, whereby materials and products are to be recycled after use in such a way that further use of the product, or the materials used is possible. This can be done in different degrees of recovery, for example by reuse, repair, recycling, remanufacturing etc. Remanufacturing offers an industrially attractive recovery option with high value retention. However, it also places the highest demands on the product to be recycled as the quality is described “as new”.The Landshut Level Model of Remanufacturing (LEMOR) is a comprehensive model for the step-by-step assessment of the suitability of a component for remanufacturing from a technical, economic and strategic perspective. This ranges from a review of the basic technical suitability to the influence of the individual damage pattern on the remanufacturing process. The assessment can be divided into a generic and a component-specific spectrum. The generic evaluation is specified in more detail by defined component properties which were collected in the component-suitability-assessment. This initial part of the evaluation shows the possibility of integrating different production processes (in particular additive manufacturing processes in combination with subtractive processes) to expand and realize high-quality and complex remanufacturing processes. A software tool was developed for the automated and user-friendly collection of component properties and their automated comparison with the requirements catalogue for testing remanufacturing suitability.

Published: December 2024

AbstractPlastic waste from packaging is being repurposed to create new products with similar processing and usage properties as virgin plastics. Understanding its composition, degradation processes, and recycling steps is essential to open up new fields of applications. To shed light on sustainable uses of recycled plastics in packaging, this paper presents interdisciplinary research which investigates and connects three areas to a holistic product view from the material to the end of production. The first area focusses on the exploration of recyclate applications by analysing and processing different recyclates and design-recyclates to identify their potential in plastic packaging products. In the second research area an evaluation model to assess the ecological sustainability of plastic packaging is developed, considering factors like material composition and processing methods. The final area focuses on developing a platform-supported information system for sharing relevant sustainability data, considering mechanisms to enhance data sharing.The challenges and opportunities of using recyclates in packaging are examined through a demonstrator product—a recyclable stand-up pouch which also contains recyclates. The analysis involves production, life cycle assessment, and utilising platforms for data sharing throughout its life cycle. The paper delves into methods to combine the practical analysis of material behaviour, the mechanisms to use and share the resulting material, machine and process data and the sustainability assessment of this data.

AbstractThis paper presents the development of solutions for the autonomous disassembly of electric motors, a vital component in the realm of e-mobility. With the escalating growth in electric vehicle (EV) production, exemplified by the registration of 10.8 million EVs worldwide in 2022 and the substantial sales of specific electric motor models, the importance of efficient recycling and disassembly processes has become more pronounced. Recognizing this, our project “Zirkel” aims to address the challenges of circular economy and resource efficiency through innovative disassembly techniques.Our methodology involved comprehensive pre-disassembly workshops to familiarize ourselves with the electric motor as a component, understanding its structure, and identifying potential challenges in the disassembly process. The workshops provided crucial insights into the specificities of electric motors used in popular EV models like the Volkswagen ID.3 and ID.4, paving the way for the development of an autonomous disassembly system.The technical challenges in developing this system were manifold, tackled through a multi-staged approach that integrates both sensorial and mechanical processes. This approach allowed us to efficiently navigate the complexities associated with the disassembly of electric motors, ensuring a balance between precision and practicality.In the demonstrator section of the paper, we elucidate the step-by-step process of overcoming these technical hurdles, detailing the development stages and the innovative solutions we employed. This includes the use of advanced automated techniques, adaptive designs, and automation of previously manual processes.

ZusammenfassungIn den vorigen Kapiteln habe ich herausgearbeitet, dass das Portfolio zum einen als Instrument für die Umsetzung einer kompetenzorientierten, standardisierten Leistungsbeurteilung, zum anderen als Werkzeug der Inklusionsförderung eingesetzt werden kann. Für die Realisierung beider Zielsetzungen ist es sicherlich nicht allein maßgebend, kann jedoch ein Gelingensfaktor neben anderen darstellen. Weiter schafft die Verfolgung beider Zielvorstellungen systeminhärente Widersprüche, die sich in den didaktischen Praktiken, hier ganz besonders in der Portfolioarbeit, auf unterschiedlichen Ebenen äußern.

ZusammenfassungDie Einleitung zum Handbuch „Sprachkulturen“ geht aus von der Geschichte des – zunächst normativen – Begriffs ‚Sprachkultur‘ und beschreibt, wie diesem eine stärker sozial- und kulturgeschichtliche Bedeutung zuwuchs, die sich für differierende Sprachgebrauchsformen auch innerhalb einer Sprache interessiert. Anknüpfend an Hinweise Dan Diners sowie an eine Monographie Stephan Braeses wird die Spezifik einer Praxis deutscher Sprachkulturen von Juden und Jüdinnen beschrieben, die seit der Haskala im Spannungsfeld von sprachassimilativen und die deutsche Sprache für jüdische Belange reklamierenden Tendenzen eine eigene (literarische) Produktivität entfaltet.
Deutsch als jüdische Sprache im Widerstreit – Überblicksartikel
Authors: Braese Stephan 
Published: December 2024

ZusammenfassungSeit der jüdischen Aufklärung zielten zahlreiche Initiativen darauf, die deutsche Sprache als ein Medium zu gewinnen, in dem genuin jüdische Themen verhandelt werden konnten und durch das Jüdisch-Sein keineswegs geschwächt, sondern gestärkt werden konnte. Allerdings war eine solche Stellung der deutschen Sprache als einer jüdischen Sprache auch innerhalb der jüdischen Gemeinschaften äußerst umstritten: Zu verschiedenen Zeiten und an verschiedenen Orten stand das Deutsche in direkter, scharfer Konkurrenz mal zum Jiddischen, mal zum Hebräischen. Die Auseinandersetzung mit diesem Konflikt prägt die Texte zahlreicher deutschsprachig-jüdischer Autor:innen bis in die Gegenwart. – Since the Jewish Enlightenment, many Jewish writers attempted to conceptualize the German language as an idiom that could express and discuss genuine Jewish subjects in a manner that might actually strengthen rather than weaken Jewishness. This function of the German language as a Jewish language has, however, been controversial among the Jewish communities. At different times and in various places, German was in stiff competition with Jewish or Hebrew. This challenge has left its mark in many texts of German speaking Jewish writers into the present.
Von der Einsetzung als ‚biblische Sprache‘
Authors: Bodenheimer Alfred 
Published: December 2024

ZusammenfassungDie Hinwendung deutschsprachiger Jüdinnen und Juden seit dem 18. Jahrhundert zur Bibel, die sich in zahlreichen Übersetzungen äußerte, dürfte weniger eine Rückkehr zu einem Ursprung hinter den rabbinischen Schriften, sondern ein Schritt in die Moderne gewesen sein. Für die Literatur des 20. Jahrhunderts lässt sich zeigen, wie sich durch ein innovatives Umgehen mit den biblischen Inhalten neue literarische Formen biblischen Sprechens bilden, die von Anlehnungen an deutschsprachige Übersetzungen und ihrer Ironisierung ebenso geprägt sind wie vom Willen, diesen Sprechduktus bewusst zu sprengen. – The focus of German-speaking Jews on the Bible since the 18th century, which manifested itself in numerous translations, may have been less a return to an origin beyond the rabbinic scriptures than a step into modernity. On the basis of examples from 20th century literature, it will be shown how new literary forms of biblical speech are created through an innovative grappling with biblical content characterized by classical borrowings from German translations and their ironization, as well as by the will to consciously break with this style of speech.

ZusammenfassungRahel Varnhagen und Rebecca Friedländer waren, obwohl Vertreterinnen des progressiven Berliner Salons, mit Selbstzweifeln und Kritik an ihren sprachlichen Fähigkeiten konfrontiert. Mit ihren Defiziten gingen die beiden Frauen unterschiedlich um: Während Rahel Varnhagen ihre Sprachverwendung produktiv nutzbar machte und Unzulänglichkeiten als authentische Zeugnisse ihres sprachlichen Ausdrucks aufwertete, versuchte Friedländer, sie durch eine übermäßige Nachahmung literarischer Traditionen zu kompensieren. – Although Rahel Varnhagen and Rebecca Friedländer were representatives of the progressive Salon in 19th century Berlin, they were confronted with self-doubts as well as criticism regarding their linguistic abilities. The two women had different approaches when it came to dealing with their deficits: While Rahel Varnhagen made productive use of her language and valorised inadequacies as authentic testimonies to her linguistic expression, Friedländer attempted to compensate for them through excessive imitation of literary traditions.
Influence of dosimetry accuracy on the correlation with treatment outcome in a preliminary PSMA radiopharmaceutical therapy study

Published: December 2024

Abstract
Introduction
Despite the potential of dosimetry in optimizing personalized radiopharmaceutical therapy (RPT), its limited clinical implementation impedes the development of simplified protocols for routine adoption. However, simplifications may introduce errors in dosimetry, prompting questions about their impact on clinical practice.

Materials and methods
In this retrospective study, we analyzed data from 21 patients diagnosed with metastatic castration-resistant prostate cancer (mCRPC) who underwent multiple cycles of 177Lu-PSMA-617 RPT treatment. Cumulative dosimetry of all the treatment cycles was calculated using both the standard multi-time point dosimetry (MTPD) method and the single time-point dosimetry (STPD, Hänscheid approximation) method for the same cohort. Their correlations with treatment outcome (PSA decline rate and overall survival, OS) and complication risk (anaemia grade) were investigated. The Fisher's Z-Transformed test was performed to statistically evaluate the difference between the correlations.

Results
STPD showed a non-significant difference in correlation with PSA decline rate, despite a mean percentage error (MPE) of up to 36.44% in tumor dosimetry compared to MTPD (MTPD: rho = -0.39, p < 0.001; STPD: rho = -0.46, p < 0.001; Z = 0.58, p = 0.56). Both STPDtotal and MTPDtotal demonstrated a significant impact on OS (STPDtotal: Hazard Ratio = 1.05, p < 0.05, log-transformed MTPDtotal: Hazard Ratio = 3.41, p < 0.05, log-transformed STPDtotal: Hazard Ratio = 8.06, p < 0.05). Additionally, despite a MPE of up to -40.26% in bone marrow dosimetry, STPD showed a non-significant difference in correlation with anemia grade (MTPD: rho = 0.35, p < 0.001; STPD: rho = 0.40, p < 0.001; Z = -0.39, p = 0.70).

Conclusion
The preliminary findings from a small cohort indicate that the reduced accuracy of a clinically simplified protocol may not diminish the clinical therapy outcome predictive value of dosimetry. Future thorough systematic investigations may be needed to determine the clinically acceptable level of accuracy for dosimetry.
Organization of the stalk system on electrocytes in mormyrid weakly electric fish Campylomormyrus compressirostris
Authors: Baumann Otto , Cheng Feng , Kirschbaum Frank , Tiedemann Ralph 
Published: December 2024

Abstract
The adult electric organ in weakly electric mormyrid fish consists of action-potential-generating electrocytes, structurally and functionally modified skeletal muscle cells. The electrocytes have a disc-shaped portion and, on one of its sides, numerous thin processes, termed stalklets. These unite to stalks leading to a single main stalk that carries the innervation site. Here, we describe the 3-dimensional layout of the stalklet/stalk system in adult Campylomormyrus compressirostris by differential interference contrast microscopy and confocal fluorescence microscopy. Using antibodies against Na+/K+-ATPase α-subunit and plasma membrane Ca2+-ATPase, we show that these ion pumps are differentially distributed over the stalklet/stalk system, with plasma membrane Ca2+-ATPase being enriched on the stalklet membrane. Stalklets are distributed and organized in a quite uniform pattern on the posterior face of the electrocyte disc and fuse to terminal stalks. The latter then unite in a mostly dichotomic mode to stalks of increasing thickness, with the main stalk measuring about 100 µm in diameter. We further analyse the structural organization of stalklets and stalks, with a characteristic cytoskeletal system of bundled actin filaments in the centre and nuclei in subsurface position. These results suggest that the stalklet/stalk system is adapted in its structural layout to generate an action potential highly synchronized over the entire disc-portion of the electrocyte, accounting for the short electric organ discharge in this species. Our results suggest that actin-related proteins overexpressed in electrocytes, as shown previously by transcriptome analysis, may be involved in the organization of the unique F-actin system in stalklets and stalks.
DIVI-Positionspapier Rettungsdienst 2030: Strategien für eine nachhaltige präklinische Notfallversorgung
Authors: Bathe Janina , Häske David , Savinsky Godo , Jacob Matthias 
Published: December 2024

ZusammenfassungDer deutsche Rettungsdienst steht vor erheblichen Herausforderungen, die durch Fachkräftemangel, demografischen Wandel und sinkende Gesundheitskompetenz der Bevölkerung verschärft werden. Um die Versorgung zu verbessern, wird eine effizientere Nutzung der Ressourcen sowie eine stärkere Integration aller beteiligten Berufsgruppen gefordert. Notfälle, die keinen Arzt erfordern, überlasten häufig die Rettungssysteme, weshalb qualifizierte Notfallsanitäter mehr Verantwortung übernehmen sollten. Zudem spielt die Leitstelle eine zentrale Rolle bei der effizienten Steuerung der Notfallressourcen. Es wird eine Erweiterung der verfügbaren Einsatzmittel, einschließlich telemedizinischer Lösungen, vorgeschlagen. Erste-Hilfe-Apps könnten ebenfalls helfen, lebensrettende Maßnahmen früher einzuleiten. Die Weiterentwicklung des Berufsbilds des Notfallsanitäters, einschließlich der Möglichkeit zur Akademisierung, soll helfen, das Personal langfristig zu binden und die Qualität der Notfallversorgung zu erhöhen. Die Einführung eines Telenotarztsystems ergänzt die Präsenznotärzte, deren Einsätze auf komplexe und lebensbedrohliche Fälle konzentriert werden sollten. Notärzte müssen umfassend qualifiziert sein, um komplexe Situationen adäquat zu bewältigen. Insgesamt erfordert ein zukunftsfähiges Rettungssystem eine reibungslose Zusammenarbeit aller Beteiligten, klare Zuständigkeiten und fortlaufende Qualitätskontrollen. Darüber hinaus ist die Implementierung einer einheitlichen standardisierten digitalen Dokumentation entlang der Rettungskette eine wesentliche Voraussetzung für die effektive intersektorale Zusammenarbeit sowie für die Qualitätssicherung in der Notfallversorgung.

Abstract
Purpose
In this feasibility study, we aimed to create a dedicated pulmonary augmented reality (AR) workflow to enable a semi-automated intraoperative overlay of the pulmonary anatomy during video-assisted thoracoscopic surgery (VATS) or robot-assisted thoracoscopic surgery (RATS).

Methods
Initially, the stereoscopic cameras were calibrated to obtain the intrinsic camera parameters. Intraoperatively, stereoscopic images were recorded and a 3D point cloud was generated from these images. By manually selecting the bifurcation key points, the 3D segmentation (from the diagnostic CT scan) was registered onto the intraoperative 3D point cloud.

Results
Image reprojection errors were 0.34 and 0.22 pixels for the VATS and RATS cameras, respectively. We created disparity maps and point clouds for all eight patients. Time for creation of the 3D AR overlay was 5 min. Validation of the point clouds was performed, resulting in a median absolute error of 0.20 mm [IQR 0.10–0.54]. We were able to visualize the AR overlay and identify the arterial bifurcations adequately for five patients. In addition to creating AR overlays of the visible or invisible structures intraoperatively, we successfully visualized branch labels and altered the transparency of the overlays.

Conclusion
An algorithm was developed transforming the operative field into a 3D point cloud surface. This allowed for an accurate registration and visualization of preoperative 3D models. Using this system, surgeons can navigate through the patient's anatomy intraoperatively, especially during crucial moments, by visualizing otherwise invisible structures. This proposed registration method lays the groundwork for automated intraoperative AR navigation during minimally invasive pulmonary resections.
