After wildfire events, water repellent soil is often found in the subsurface layer of channel bed burnt area. Debris flows generated from basins and ensuing entrainment pose imminent threat to infrastructure human lives. However, fundamental interaction mechanisms debris flow overriding resulting impact force on debris-resisting barriers have yet be elucidated. In this study, physical flume exp...

OBJECTIVES Our aim was to evaluate Korea's Pandemic Influenza Preparedness Plan. METHODS We conducted a sensitivity analysis on the expected number of outpatients and hospital bed occupancy, with 1,000,000 parameter combinations, in a situation of pandemic influenza, using the mathematical simulation program InfluSim. RESULTS Given the available resources in Korea, antiviral treatment and s...

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...

The kinetic of Fischer-Tropsch synthesis over a co-precipitated Fe-Ce catalyst was investigated in a fixed bed micro reactor. Experimental conditions were varied as follow: reaction pressure 1-15bar, H¬¬¬2/CO feed ratio of 1-3 and space velocity of 3600-5400 h-1 at the temperature range of 270-310°C. 4 models according to the Langmuir-Hinshelwood-Hougen-Watson (LHHW) type rate equation were der...

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...

What makes us repeat behaviors compulsively that we ultimately regret? One intriguing behavior is that of binge eating—a pattern of food intake that is defined as recurring episodes of rapid, out-of-control overeating in which food is consumed in larger amounts than normal over a short period of time to the point of being uncomfortably full. Binge eating disorder (BED) has been accepted in The ...

The dynamics of blood supply to a vascular bed depend on lumped mechanical properties of that bed, namely the compliance (C), resistance (R), viscoelasticity (K), and inertance (L). While the study of regulatory mechanisms has so far placed the emphasis largely on R, it is not known how the remaining properties contribute collectively to the play of dynamics in vasomotor control. To examine thi...

Title of dissertation: SEDIMENT SUSPENSION EVENTS FROM RIPPLE BEDS IN OSCILLATORY FLOW: EXPERIMENTS Philip Leland Knowles Doctor of Philosophy, 2009 Dissertation directed by: Associate Professor Kenneth T. Kiger Department of Mechanical Engineering An experimental sediment flume is used to investigate sediment transport mechanics within an oscillatory turbulent boundary layer over a mobile sedi...

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...
