Detailed field measurements and simulations of three-dimensional flow structure were used to develop a conceptual model to explain the sustainability of self-formed pool-riffle sequences in gravel-bed rivers. The analysis was conducted at the Red River Wildlife Management Area in Idaho, USA, and enabled characterization of the flow structure through two consecutive pool-riffle sequences, includ...

BACKGROUND Laccases have good potential as bioremediating agents and can be used continuously in the immobilized form like many other enzymes. METHODS In the present study, laccase from Cyathus bulleri was immobilized by entrapment in Poly Vinyl Alcohol (PVA) beads cross-linked with either nitrate or boric acid. Immobilized laccase was used for dye decolorization in both batch and continuous ...

Liquid injection in fluidized beds occurs well-established industrial processes as fluid coking, spray fluidzed bed granulation and condensed mode gas-phase polymerisation. These still suffer performance issues due to their complex nature, where liquid adds even more complexity. In this work, the effect of on temperature uniformity a pseudo-2D was studied using Infra-Red Thermography. The image...

OBJECTIVE To determine whether critically ill patients who receive allogenic packed red blood cell transfusions are at increased risk of developing nosocomial infections during hospitalization. DESIGN Retrospective database study utilizing Project IMPACT. SETTING A 40-bed medical-surgical-trauma intensive care unit in an 825-bed tertiary referral teaching hospital. PATIENTS One thousand s...
