In this paper, a new design of conical coaxial magnetic gear was proposed. Conical gears are considered logical link between the radial- and axial-field designs. The modeling torques based on 3D finite element method developed. parameter variations were determined discussed. torque density calculated compared with that cylindrical same size materials used. An optimal cone angle air-gap length M...

Tracheostomy can influence the work of breathing by introducing additional resistance to airflow through the native airway. In a 1996 study, Hussey and Bishop determined that the presence of a deflated cuff in the airway significantly increased the work of breathing and theorized that a lower profile cuff would introduce less resistance to airflow. Hussey and Bishop also demonstrated that the p...

Single- and multiple-nanopore membranes are both highly interesting for biosensing and separation processes, as well as their ability to mimic biological membranes. The density of pores, their shape, and their surface chemistry are the key factors that determine membrane transport and separation capabilities. Here, we report silicon nitride (SiN) membranes with fully controlled porosity, pore g...

In this study, the starting time of ghost fishing in baited fish traps were determined. Two separate trials using 4 different types (foldable, conical, “O” shaped Round and cylindrical) carried out Çanakkale Strait at a depth 5m between July - December 2013. A total 12 (3 for each trap type) used study. Each trial lasted period 45 days. Major features as follows: foldable had “V” inclined funne...
