In this study the effects of different concentrations of antibiotics levofloxacin and ceftriaxone on maggot development, weight, length, and mortality were examined. The maggot length and weight were significantly increased by therapeutical doses of levofloxacin and ceftriaxone. The maggot development time was significantly decreased in every levofloxacin treatment compared to the control. The time to start pupation was significantly increased in the control compared to the antibiotic treatments. Levofloxacin significantly increased the survivability of the maggots. Every levofloxacin treatment significantly improved the rearing conditions for the maggots. Reaching the third instar was delayed by 24 h in the control compared to the Levo 3.57 treatment. The Pupation in the control was delayed by an average of 48 h compared to the Levo 3.57 treatment. The significantly reduced development time of the maggots in the antibiotic treatments might lead to an overestimation of the post-mortem interval and therefore an incorrect time of death determination. The improved rearing conditions may be an indication of the potential of a combined application of antibiotics and maggot therapy.}, language = {en} } @misc{PreusserFischerJuretzek, author = {Preußer, Daniel and Fischer, Thomas and Juretzek, Thomas}, title = {Effects of antibiotics ceftriaxone and levofloxacin on the growth of Lucilia sericata (Diptera: Calliphoridae)}, series = {Medical and Veterinary Entomology}, volume = {37}, journal = {Medical and Veterinary Entomology}, number = {4}, issn = {0269-283X}, doi = {10.1111/mve.12685}, pages = {805 -- 815}, abstract = {Lucilia sericata is one of the most studied species in forensic entomology due to its widespread distribution, forensic importance as well as medical use. The growth and development stage of maggots is often used to determine the post-mortem interval in forensic cases. L. sericata can cause myiasis in humans who are not able to maintain personal hygiene due to age or medical condition and can therefore be used to determine the time period of neglect. The influence of the temperature on the maggot development has been examined in various studies. Different examinations on the effects of toxic substances on the maggot development and survival have been conducted in order to test the influence and resulting deviations. In this study, the effects of different therapeutical doses of the antibiotics ceftriaxone and levofloxacin were examined on L. sericata in order to determine and compare deviations in maggot development and survival. The used antibiotics did not significantly influence the maggot weight and length. A significant delay in the time of pupation has been determined in the treatments with high concentrations of levofloxacin. The mortality was significantly increased in all treatments with antibiotics compared to the control, whereby the survivability of all treatments remained over 80\%. Because of the high doses needed to produce an effect, we concluded that an overestimation of the post-mortem interval is unlikely but higher antibiotic concentrations or possible interactions with other medications could increase the maggot development time.}, language = {en} } @misc{BerkmannPovolniSchwarzetal., author = {Berkmann, Fritz and Povolni, Pavel and Schwarz, Daniel and Fischer, Inga Anita}, title = {Influence of material and geometry parameters on resonance linewidths of plasmonic modes in gratings made from highly doped Ge1-xSnx}, series = {Journal of Physics D: Applied Physics}, volume = {57}, journal = {Journal of Physics D: Applied Physics}, number = {43}, doi = {10.1088/1361-6463/ad67ea}, pages = {10}, language = {en} } @misc{EisenhauerFrankWeigeltetal., author = {Eisenhauer, Nico and Frank, Karin and Weigelt, Alexandra and Bartkowski, Bartosz and Beugnon, R{\´e}my and Liebal, Katja and Mahecha, Miguel and Quaas, Martin and Al-Halbouni, Djamil and Bastos, Ana and Bohn, Friedrich J. and Brito, Mariana Madruga de and Denzler, Joachim and Feilhauer, Hannes and Fischer, Rico and Fritsche, Immo and Guimaraes-Steinicke, Claudia and H{\"a}nsel, Martin and Haun, Daniel B.

This paper examines the interconnectedness of soil biodiversity, climate change, and societal impacts, emphasizing the urgent need for integrated solutions. Human-induced biodiversity loss and climate change intensify environmental degradation, threatening human well-being. Soils, rich in biodiversity and vital for ecosystem function regulation, are highly vulnerable to these pressures, affecting nutrient cycling, soil fertility, and resilience. Soil also crucially regulates climate, influencing energy, water cycles, and carbon storage. Yet, climate change poses significant challenges to soil health and carbon dynamics, amplifying global warming. Integrated approaches are essential, including sustainable land management, policy interventions, technological innovations, and societal engagement. Practices like agroforestry and organic farming improve soil health and mitigate climate impacts. Effective policies and governance are crucial for promoting sustainable practices and soil conservation. Recent technologies aid in monitoring soil biodiversity and implementing sustainable land management. Societal engagement, through education and collective action, is vital for environmental stewardship. By prioritizing interdisciplinary research and addressing key frontiers, scientists can advance understanding of the soil biodiversity-climate change-society nexus, informing strategies for environmental sustainability and social equity.}, language = {en} } @misc{BerkmannSteuerGanssetal., author = {Berkmann, Fritz and Steuer, Oliver and Ganss, Fabian and Prucnal, Slawomir and Schwarz, Daniel and Fischer, Inga Anita and Schulze, J{\"o}rg}, title = {Sharp MIR plasmonic modes in gratings made of heavily doped pulsed laser-melted Ge1-xSnx}, series = {Optical Materials Express}, volume = {13}, journal = {Optical Materials Express}, number = {3}, issn = {2159-3930}, doi = {10.1364/OME.479637}, pages = {752 -- 763}, language = {en} } @misc{MajedSchachtFischeretal., author = {Majed, Jihed Ben and Schacht, Ralph and Fischer, Tim and Zajaczkowski, Marek and May, Daniel and Pareek, Kaushal Arun and Zafar, Syed Ali}, title = {Anwendung der Lock-in-Thermographie zur Defekterkennung in additiv gefertigten AMC Schweißn{\"a}hten}, series = {DGZfP 2025 : DGZfP-Jahrestagung 2025, 26.-28.

Im Rahmen der F{\"o}rderbekanntmachung „WIR! - Wandel durch Innovation in der Region" des Bundesministeriums f{\"u}r Bildung und Forschung (BMBF) wird im Teilvorhaben „Inline-Prozesskettenentwicklung zum Reparieren von AMC-Werkstoffen sowie Porendetektion mittels aktiver IR-Thermographie zur Prozess{\"u}berwachung" eine Machbarkeitsstudie zur Nutzung der Lock-in-Thermographie (LIT) zur Defekterkennung in AMC-Schweißn{\"a}hten durchgef{\"u}hrt. Ziel der Machbarkeitsstudie ist es, die Anwendbarkeit der LIT f{\"u}r die Inline-Prozess{\"u}berwachung dieses Werkstoffs zu bewerten, da dessen thermische und mechanische Eigenschaften, darunter eine thermische Diffusivit{\"a}t von etwa 8,6 * 1E-5 m²/s, besondere Herausforderungen f{\"u}r die zerst{\"o}rungsfreie Pr{\"u}fung (ZfP) darstellen. Die LIT, bei der eine modulierte W{\"a}rmequelle verwendet wird, erlaubt die Erkennung von ‚subsurface' Defekten durch die Analyse der thermischen Wellen. Es werden verschiedene Algorithmen eingesetzt, um die thermischen Daten zu analysieren und die thermische Empfindlichkeit der verwendeten Kamera zu simulieren. Neben den experimentellen Untersuchungen werden FEM-Simulationen genutzt, um optimale Betriebsparameter wie Modulationsfrequenz und notwendige Laserleistung zu bestimmen. So konnten bereits zuverl{\"a}ssig Defekte ab 2 mm Gr{\"o}ße bis zu 1,5 mm Tiefe unter der Oberfl{\"a}che detektiert werden. Die FE-Simulationsergebnisse zeigen zudem, dass durch Anpassungen der Anregungsfrequenz sowie weiterer Parameter wie Energieeintrag, Kamerasensitivit{\"a}t und Auswertemethoden auch kleinere, tiefer liegende Defekte erkannt werden k{\"o}nnen. Die ersten Ergebnisse zeigen, dass die LIT auch f{\"u}r additiv gefertigte Metalllegierungen f{\"u}r die pr{\"a}zise Identifizierung verborgener Defekte einsetzbar ist und somit In-line zur Steigerung der Produktionssicherheit sowie der Produktqualit{\"a}t beitragen.}, language = {de} }
