Obstetrics and gynecology devices designed for low‐ and middle‐income countries: A narrative review
International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 71-80, April 2025.Abstract There are many barriers contributing to poor health outcomes for women in low‐ and middle‐income countries (LMICs), one of which is the lack of necessary medical devices. Presently, the development of various kinds of devices intended to improve women's health outcomes specifically in LMICs remains underrepresented in the literature; therefore,

Piston Rotation and Frictional Forces between Piston and Cylinder of Piston Pump and Motor.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1993 The influence of the piston rotation on the frictional forces between the piston and the cylinder has been studied experimentally for a swash plate type piston pump and motor. In order to measure the rotational speeds of the piston, the capacitance detecting method has been employed for the piston with the slits.
