OBJECTIVES Residents of nursing homes often have difficulty swallowing (dysphagia), which complicates the administration of solid oral dosage formulations. Erroneously crushing medication is common, but few interventions have been tested to improve medication safety. Therefore, we evaluated the effect of warning symbols in combination with education on the frequency of erroneously crushing medi...

This paper presents the development of a new 3D finite element model for simulation UD composites materials under crushing, at mesoscale. It is based on Discrete Ply Model (DPM), enhanced with damage law to represent compression constant stress due localised crushing and its propagation from one another. The aims take into account various types involved in laminates during associated absorbed e...

Motor functions of masticatory organs such as the tongue, lips, cheeks and mandible are known to deteriorate with age, thereby influencing masticatory performance. However, there are few reports on the relationships between tongue and lip functions and masticatory performance. To investigate the relationship between tongue and lip functions and comprehensive masticatory performance, by evaluati...

This work presents force control in dual arm planar cooperative space robot for cooperative manipulation by two arms. A docking operation by the two arms of the space manipulator has been carried out. During docking operation, space robot requires mechanical interaction with compliant objects, which encounter force and motion constraints. The gripping force should be such that the object should...

Automotive crash boxes require a material selection with strength and ductility in balanced combination. In this work, the behaviour of double-chamber AA6063 AA6082 aluminium profiles subjected to quasi-static dynamic axial crushing was studied experimentally. The were stretched two different levels between extrusion artificial ageing temper T6. higher pre-stretch resulted more ductile slightly...

It is shown that the initial singularities in spatially compact spacetimes with spherical, plane or hyperbolic symmetry admitting a compact constant mean curvature hypersurface are crushing singularities when the matter content of spacetime is described by the Vlasov equation (collisionless matter) or the wave equation (massless scalar field). In the spherically symmetric case it is further sho...

The aim of this study was to investigate the effect of platelet-rich plasma (PRP) on cavernous nerve (CN) regeneration and functional status in a nerve-crush rat model. Twenty-four Sprague-Dawley male rats were randomly divided into three equal groups: eight had a sham operation, eight underwent bilateral nerve crushing with no further intervention and eight underwent bilateral nerve crushing w...

A case of hamate dislocation is presented. This is associated with subluxation of the fourth and fifth metacarpi bones with the hamate in a dorsal direction. No other capital or metacarpus injury was involved. The mechanism of injury was a direct crushing force. A close reduction was attempted successfully with percutaneous K-wire fixation. These were removed after 6 weeks and physiotherapy con...
