BACKGROUND Recently, research on tissue-engineered skin substitutes have been active in plastic surgery, and significant development has been made in this area over the past several decades. However, a regenerative skin flap has not been developed that could provide immediate blood flow after transplantation. Here, we make a regenerative skin flap ex vivo that is potentially suitable for micros...

This work is aimed to produce endoglucanase through solid state fermentation in a packed bed bioreactor with the use of the fungus Myceliophtora sp. I-1D3b using a mixture of wheat bran (WB) and sugar cane bagasse (SCB) as culture medium. Preliminary tests were performed in polypropylene plastic bags, controlling the variables temperature (40, 45, and 50°C), initial moisture content (75, 80, an...

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...

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...

Glucose, enzymatically released from pulp fiber sludge, was combined with inorganic salts and used as a growth medium for Alcaligenes eutrophus, a gram-negative strain producing poly(3-hydroxybutyrate) (PHB). By controlling the concentrations of the inorganic salts in the growth medium, almost 78% of the cell mass was converted to pure PHB. Efforts were made to find conditions for bacterial gro...

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...
