The purpose of this study was to evaluate a technique of pushing a wheelchair at the level of the handle bars as a method for measuring rolling resistance of wheelchair-user systems under different field conditions. Under standardized conditions on a motor driven treadmill, rolling resistance was determined using a 2D strain gauge-based push technique at the level of the handle bars and a commo...

This study was designed to analyze upper extremity and core muscle activation performing push-ups under different stability conditions and body positions. Trained university male students (n= 29) performed 3 push-ups each under stable conditions and using suspension device (AirFit Trainer ProTM) with their hands at 2 different heights (i.e., 10 and 65 cm). Push-up speed was controlled using a m...

Diesel particulate matter (DPM) is considered to be carcinogenic after prolonged exposure. With more diesel-powered equipment used in underground mines, miners' exposure to DPM has become an increasing concern. This paper used computational fluid dynamics method to study the DPM dispersion in a dead-end entry with loading operation. The effects of different push-pull ventilation systems on DPM ...

OBJECTIVE Interprofessionalism (IP) has emerged as a new movement in healthcare in response to workforce shortages, quality and safety issues and professional power dynamics. Stakeholders can push for IP (e.g. education providers to the health system) or pull (e.g. the health system to the education provider). Based on innovation theory, we hypothesized that there would be unequal forces within...

INTRODUCTION The purpose of this study was to compare the push-out bond strength of white ProRoot Mineral Trioxide Aggregate (MTA), Biodentine, calcium-enriched mixture (CEM) cement and Endosequence Root Repair Material (ERRM) putty after exposure to blood. METHODS AND MATERIALS A total of 96 root dentin slices with a standardized thickness of 1.00±0.05 mm and standardized canal spaces were r...

A great deal of research has investigated the potential parameters of tactile feedback for virtual buttons. However, these studies do not take the possible effects of feedback latencies into account. Therefore, this research investigates the impact of tactile feedback delays on touchscreen keyboard usage. The first experiment investigated four tactile feedback delay conditions during a number e...

This paper explores the potentially powerful role e-assessment practices can have on culture change in learning and teaching. This paper demonstrates how new e-assessment practices can ‘push back’ through educational institutions. This is done by applying the work of Gibbs and Simpson (2004/5) to e-assessment practices. To illustrate the practical effects of this evidence-based framework, the a...

Ropinirole hydrochloride is indicated in Parkinson’s disease and Restless leg syndrome. In advanced Parkinson’s disease the usual dose of Ropinirole hydrochloride is 0.25 to 5 mg three to four times a day. Hence, an attempt was made to develop a once-a-day controlled release Osmotic drug delivery system. This may offer significant patient benefits by providing enhanced efficacy and reduced side...

BACKGROUND Offshore medical schools are for-profit, private enterprises located in the Caribbean that provide undergraduate medical education to students who must leave the region for postgraduate training and also typically to practice. This growing industry attracts many medical students from the US and Canada who wish to return home to practice medicine. After graduation, international medic...
