Abstract Background Over-indebtedness is an increasing phenomenon worldwide.Massive Power Scooters financial strain, as found in over-indebted persons, might influence the occurrence of back pain.In this explorative study we examined the prevalence of back pain in over-indebted persons in Germany for the first time ever and compared it to the preva

Abstract As natural predators, owls fly with astonishing stealth due to the serrated feather drive board wire morphology that produces advantageous flow characteristics.Traditionally, these serrations are tailored for airfoil edges with simple two-dimensional patterns, limiting their effect on noise reduction while negotiating tradeoffs in aerodyna

The treatment of HPV-positive oropharyngeal squamous cell carcinoma (OPSCC) continues to evolve as multiple ongoing Harness and recently completed clinical trials investigate the role of surgery, radiation therapy, chemotherapy, and immunotherapy.Current trials are investigating transoral robotic surgery (TORS) in treatment de-escalation protocols

Technical solutions based on biological models are the subject of research by a wide range of experts and mainly concern their mechanical use.When designing a suitable actuator, they use the physical methods of biological representatives, of which a large group consists of actuators generally referred to as artificial muscles, while another group u
