Pre‐Curved Everting Robots With Embedded Steering Intelligence Fabricated by CO2 Laser Welding

Advanced Intelligent Systems, EarlyView.
Design and experimental demonstration of a laser welded growing robot for anatomically guided navigation. The robot follows an aortic arch phantom entering the branchiocephalic branch through steering by design. The figure shows the physical phantom setup, CAD defined weld geometry and full robot eversion.

#AlleredenvomWetter #FridaysforFuture #FFF

, 2019
Die Umsetzung zu diesem Poster kam meiner Tochter, als sie sich mal wieder mit der Schulpflicht auseinandersetzen musste, die das Engagement für die Klimapolitik bremst. Besonders ärgert sie in diesem Zusammenhang, dass nur über die Schulpflicht, statt über mögliche Umweltschutz Sofortmaßnahmen diskutiert wird.

Influence of Annealing Temperature on the Thermomechanical Properties and Dimensional Stability of FFF‐Printed PET‐CF

Journal of Applied Polymer Science, EarlyView.
Following extrusion at 265°C, components underwent a 45‐min annealing process at temperatures from 145°C to 225°C. The results show that increasing the annealing temperature elevates the onset of thermal softening, significantly enhancing thermal reliability.

Flattening Filter-Free Beams in Intensity-Modulated Radiotherapy and Volumetric Modulated Arc Therapy for Sinonasal Cancer. [PDF]

PLoS ONE, 2016
To evaluate the dosimetric impacts of flattening filter-free (FFF) beams in intensity-modulated radiotherapy (IMRT) and volumetric modulated arc therapy (VMAT) for sinonasal cancer.For fourteen cases, IMRT and VMAT planning was performed using 6-MV ...

The Strategic Role of Sustainability Certifications: A Multi‐Theoretical Framework and Comparative Analysis in the Global Wine Industry

Business Strategy and the Environment, EarlyView.
ABSTRACT Sustainability certifications are increasingly embedded in the governance and competitiveness of the wine sector, yet their strategic role remains under‐theorised. This study conceptualises certifications as multidimensional strategic mechanisms and conducts a comparative analysis of 50 schemes used in the global wine industry.

Comparison of the dose distribution of the VMAT radiotherapy technique depending on the beam used: FFF-X10MV and FFF-X15MV

Reports of Practical Oncology and Radiotherapy, 2023
The aim of the study was to answer the question of whether flattening filter (FF) and flattening filter-free (FFF) beams can be used alternately in the volumetric modulated arc therapy (VMAT) treatment technique, regardless of the size of the irradiated volume [small (S) or large (L) planning target volume (PTV)].Two groups of patients were examined: a

Design and implementation of a 3D‐printed modular distillation tower for experimental teaching in chemical engineering

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Several authors have reported the disconnection between the skills, abilities, and attitudes of graduates from STEM careers with the current needs of the labour market. In science and engineering fields, research has found the need for interdisciplinary approaches that encourage meaningful learning.
