  • Faculty of Mechanical Engineering

  Najczęściej stosowanym materiałem do produkcji implantów jest tytan. Każdy implant przed dopuszczeniem do produkcji przechodzi szereg prób laboratoryjnych określających jego zdolność do przenoszenia obciążeń przez określony, możliwie długi czas. Próby przeprowadzane są na maszynach symulujących ruchy, jakie implant ma wykonywać w organizmie z użyciem siły kilkakrotnie przekraczającej wartości występujące ...

  - Weather Climate and Society - Year 2022

  Adverse weather such as rain, snow, and fog may significantly reduce visibility or change adhesion properties and, as a consequence, affect drivers’ sense of safety, driving comfort, and their reaction to a changing driving environment (i.e., lower speed and increased headways). The changed behavior of individual drivers affects both traffic flow characteristics, that is, average speed and headways, and parameters related to highway...

  Electron impact ionization of helium nano-droplets containing several 104 He atoms and doped with CCl4 or SF6 molecules is studied with high-mass resolution. The mass spectra show significant clustering of CCl4 molecules, less so for SF6 under our experimental conditions. Positive ion efficiency curves as a function of electron energy indicate complete immersion of the molecules inside the helium droplets in both cases. For CCl4...
