The present study was to obtain basic data for applying the short stick exercises to frail elderly individuals. A total of 20 individuals aged ≥60 years (10 men, and 10 women) with independence in activities of daily living participated in a short stick exercise program. During the exercise program, the time required and the number of times the short stick was dropped were investigated. The exe...

BACKGROUND Needle stick and sharp injuries were one of the major risk factors for blood and body fluid borne infections at health care facilities. OBJECTIVE To assess occupational exposure to needle stick and sharp injuries and associated factors among health care workers in Awi zone, 2016. METHODS institutional based cross-sectional study was conducted among 193 health care workers. Study ...

An intelligent guide stick for the blind was developed. It consists of an ultrasound displacement sensor, two DC motors, and a micro-controller. The total weight is 4.0kg, and the width and the height of the guide stick are 24cm and 85cm, respectively. Computer simulations were performed in order to find the traces of the guide stick at three different paths using an in-house Visual C software....

The authors describe the stick utilization of Veirs modified as modelling intracanalicular facilitating canaliculo suture lachrymal and avoiding its estenose. The technique consists in the stick introduction of Veirs modified in the lumen canalicular by the lacrimal point, in direction to the lachrymal sack. To follow the distal terminations and near of canaliculo hurt are identified and the la...

This paper addresses issues of mechanical emulation of sti walls and stick-slip friction with a 6-DOF magnetically levitated joystick. In the case of sti wall emulation, it is shown that the PD control implementation commonly used severely limits achievable wall damping and sti ness. It is also shown that the perceived surface sti ness can be increased without loss of stability by applying a br...

This article focuses on developing a novel trans-scale precision positioning stage based on the stick-slip effect. The stick-slip effect is introduced and the rigid kinematics model of the stick-slip driving is established. The forward and return displacement equations of each step of the stick-slip driving are deduced. The relationship of return displacement and the acceleration produced by fr...
