Pulmonary arterial cannulation is a common and effective method for percutaneous mechanical circulatory support for concurrent right heart and respiratory failure [1]. However, limited data exists to what effect the positioning of the cannula has on the oxygen perfusion throughout the pulmonary artery (PA). This study aims to evaluate, using computational fluid dynamics (CFD), the effect of different cannula positions in the PA with respect to the oxygenation of the different branching vessels in order for an optimal cannula position to be determined. The four chosen different positions (see Fig. 1) of the cannulas are, in the lower part of the main pulmonary artery (MPA), in the MPA at the junction between the right pulmonary artery (RPA) and the left pulmonary artery (LPA), in the RPA at the first branch of the RPA and in the LPA at the first branch of the LPA.
Humic substances possess distinctive chemical features enabling their use in many advanced applications, including biomedical fields. No chemicals in nature have the same combination of specific chemical and biological properties as humic substances. Traditional medicine and modern research have demonstrated that humic substances from different sources possess immunomodulatory and anti-inflammatory properties, which makes them suitable for the prevention and treatment of chronic dermatoses, allergic rhinitis, atopic dermatitis, and other conditions characterized by inflammatory and allergic responses [1-4]. The use of humic compounds as agentswith antifungal and antiviral properties shows great potential [5-7].
This study presents the concept of AstroBioLab, an autonomous astrobiological field laboratory tailored for the exploration of (sub)glacial habitats. AstroBioLab is an integral component of the TRIPLE (Technologies for Rapid Ice Penetration and subglacial Lake Exploration) DLR-funded project, aimed at advancing astrobiology research through the development and deployment of innovative technologies. AstroBioLab integrates diverse measurement techniques such as fluorescence microscopy, DNA sequencing and fluorescence spectrometry, while leveraging microfluidics for efficient sample delivery and preparation.

Lehrmaterial für den Tiroler Skilehrerverband: Konzeption für eine crossmediale
Neugestaltung
(2024)
Der Tiroler Skilehrerverband bereitet angehende Skilehrer:innen auf die verschiedenen Schneesportlehrer-Prüfungen vor. Skilehrer:innen spielen eine entscheidende Rolle im Erfolg des Wintertourismus, was ihre gesellschaftliche und wirtschaftliche Relevanz unterstreicht. Die zeitgemäße Neugestaltung des Lehrmaterials soll eine effektive Vermittlung von Lerninhalten ermöglichen. Durch die Kombination von Informationsdesign, Corporate Design und Editorial Design wird die Verständlichkeit und Attraktivität des Materials gesteigert. Die Integration einer Lernapp ermöglicht eine interaktive und multimediale Lernerfahrung sowie mehr Flexibilität für die Lernenden. Die crossmediale Neugestaltung wirkt den Problemen veralteter Darstellungsformen entgegen. Es wird deutlich, dass gut gestaltetes Lehrmaterial bei gleichbleibenden Inhalten zu einer besseren Lernerfahrung führt.

Mit über 1300 Büdchen in 86 Veedeln ist Köln Deutschlands Kiosk-Hauptstadt. Sie sind ein prägendes Element von Nachbarschaften und gehören zum Kölner Stadtbild einfach dazu wie der Dom und der Rhein. Durch Anekdoten, Interviews, Beiträge zur Popkultur, alte Fotografien, Momentaufnahmen und vertraute Grafiken sowie einer festen Formsprache entsteht das erste Büdchenmagazin für Köln. Das Periodikum erscheint alle drei Monate und liegt kostenfrei in den Büdchen aus. Es ist eine Publikation die beweist, dass Büdchen mehr als gängige Verkaufsstellen sind, sondern Knotenpunkte unserer Gesellschaft.
A novel method to determine the extruded length of a metallic wire for a directed energy deposition (DED) process using a microwave (MW) plasma jet with a straight-through wire feed is presented. The method is based on the relative comparison of the measured frequency response obtained by the large-signal scattering parameter (Hot-S) technique. In the practical working range, repeatability of less than 6% for a nonactive plasma and 9% for the active plasma state is found. Measurements are conducted with a focus on a simple solution to decrease the processing time and reduce the integration time of the process into the existing hardware. It is shown that monitoring a single frequency for magnitude and phase changes is sufficient to achieve good accuracy. A combination of different measurement values to determine the length is possible. The applicability to different diameter of the same material is shown as well as a contact detection of the wire and metallic substrate.
