the excellent performance of fluidized bed heat exchangers is due to the interaction between particles and heat transfer surface and to the mixing effects in the viscous sublayer. in this paper, the results of experimental investigations on heat transfer for a wide range of newtonian and non-newtonian (shear-thinning power law) fluids are presented. new design equations have been developed for ...

abstract for investigating the effect of bed form in alluvial channels on the amount of bed load transport, a set of experiments was carried out in a tilting flume under unsteady flow conditions (hydrograph). the produced hydrographs were in triangular form with a maximum discharge of 30 to 45 lit/s/m. three size of sediment particles were used with equal to 1.5, 2.1 and 3.0mm, clear water with...

background increasing demand for limited healthcare resources raises questions about appropriate use of inpatient beds. in the first paediatric bed utilisation study at a regional university centre in ireland, we conducted a cross-sectional study to audit the utilisation of inpatient beds at the regional paediatric unit (rpu) in university hospital limerick (uhl), limerick, ireland and also exa...

The number of hospital beds per head of population has fallen by more than 2% a year since 1980. Levels of bed occupancy have risen during this period. Appropriate bed occupancy is crucial to the NHS, as occupancy rates exceeding 85% in acute hospitals are associated with problems in dealing with emergency and elective admissions. We aimed to develop a valid instrument for the objective assessm...

Although the complications of immobility are well-described in the literature, critically ill patients are often subjected to prolonged periods of bed rest. Nurses, by virtue of their expertise in preventing iatrogenic complications, are in an ideal position to prevent the adverse outcomes associated with immobility. This article describes how nurses can use a mobility protocol to increase the ...

A new HIGEE device-rotating zigzag bed (RZB) was developed in the context of process intensification. The RZB is structurally featured by a combinatorial rotor of one series of baffles attached to a rotating disk with another series to a stationary disk. The novel structure of the RZB determines its many advantages over the other HIGEE devices. The RZB is free of dynamic seal, capable of interm...
