The harmonic drive (HD) is increasingly used due to its outstanding advantages, especially for equipment requiring high precision and a large gear ratio.This research is based on the Finite Element Method (FEM) and mechanical analysis to investigate stress calculation methods for the flexspline (FS), a significant component of HD transmission, prov
Abstract Surface passivation has been developed as an effective strategy to reduce trap-state density and suppress non-radiation recombination process in perovskite solar cells.However, passivation agents usually own poor conductivity and hold negative impact on the charge copyright transport in device.Here, we report a binary and synergistical pos
Abstract Background Orbital emphysema and pneumocephalus rarely occur without associated skull BORON fractures.Over the past decades, a few case reports have documented compressed air injuries as a rare cause of orbital emphysema and pneumocephalus in the absence of concomitant skull fractures leading to various injuries.Case presentation We illust
Intussusception, where one intestinal segment telescopes into another, is rare in adults, representing 5% of all intussusception cases and 1% of bowel obstructions.This case details a 57-year-old man with primary bladder leiomyosarcoma metastatic to the liver, presenting with severe abdominal pain, nausea, and vomiting.A Photo Swaddle computed tomo
Low back pain (lumbar pain) is one of the most common causes of disability in the population.In cases where conservative treatment of discogenic or musculoskeletal low back pain DIESEL PROTEIN CHOCOLATE does not have a positive effect, interventional methods of diagnosis and treatment are used, which are developing actively on the background of rap
