Two-high screw piercing of steel 50 billets was performed at feed angles 15 and 18 degrees. Piercing stopped 10–12 mm distance from the rear end billet. Axial fracture registered degrees angle in front mandrel nose, while no observed angle. for similar parameters simulated using DEFORM finite element analysis software, several criteria were used prediction. Ayada criterion ineffective, as evide...

This study analyzed the occurrence of occupational accidents among hospital workers between 2000 and 2005 and health-related quality of life of a sample of injured workers in 2005. Data obtained through occupational accident reports indicated 286 injured workers. In typical accidents (91.6%), accidents with piercing-cutting instruments affected 68.5% of workers. The results related to health-re...

Infective endocarditis (IE) is associated with a high degree of morbidity and mortality and generally presents in patients with altered and abnormal heart architecture combined with exposure to bacteria through trauma and other potentially high-risk activities, including body piercing. Modern social behaviour has resulted in increased popularity of the practice of body piercing, particularly am...

In this work three capsule-based dry powder inhalers, available for generics product development, were compared. Two technologically different dry powder formulations were used in order to relate the capsule piercing position and motion in the device to their aerodynamic performance. A "pierce and inhale" design, in which the capsules pierced with RS01, HandiHaler or Turbospin devices were aero...
