Trauma patients who succumb to their injuries do so by one of several mechanisms discussed in this article. The most common include head injury, exsanguination, sepsis, and multiple organ failure. The article also discusses adverse consequences of hypothermia, including a model for calculating total heat loss.
Liquid fluidized beds containing porous magnetic ion-exchange particles with densities ca. 1.03-1.16 g mL-1 were examined. The effect of magnetic stabilization was studied, both in terms of bed physical characteristics and sorptive behavior. Maximum applied magnetic field strength was approximately 200 oersted. Breakthrough and pulse analyses were carried out with protein and acetone solutions, respectively, with liquid flow rates ranging from approximately 1 to 3 cm min-1. Acetone pulses in columns containing 7 mL of particles had plate numbers ranging from 2.5 to 18 for magnetically stabilized beds and from 7.8 to 20 for non-stabilized fluidized beds. Under any particular set of conditions, magnetic stabilization always resulted in poorer efficiency, both in pulse analyses and in protein breakthrough experiments.
Membranes that use a reversible chemical reaction or sequestration to achieve high selectivities and productivities show great potential for use in bioseparations. The concept of liquid membranes, with and without a complexing agent (carrier), and the types of system configurations and carriers that may be used with these membranes, are discussed.
