#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.

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

Medusan Morphospace: Phylogenetic Constraints, Biomechanical Solutions, and Ecological Consequences [PDF]

, 2008
Medusae were the earliest animals to evolve muscle-powered swimming in the seas. Although medusae have achieved diverse and prominent ecological roles throughout the world\u27s oceans, we argue that the primitive organization of cnidarian muscle tissue ...

Exposing and harvesting metadata using the OAI metadata harvesting protocol: A tutorial [PDF]

, 2001
In this article I outline the ideas behind the Open Archives Initiative metadata harvesting protocol (OAIMH), and attempt to clarify some common misconceptions. I then consider how the OAIMH protocol can be used to expose and harvest metadata.
