  • fluid removal
  • More total time dialyzing, shorter periods between treatments and the fact that fluid removal speeds can be lower (thus reducing the symptoms resulting from rapid ultrafiltration), accounts for the advantages of these schedules over conventional ones. (wikipedia.org)
  • Coefficient
  • The variable dm/dt is the rate of mass transfer into the gas phase, De is the average diffusion coefficient of free aroma molecules in the emulsion, Agc is the surface area of the gas/food interface, tc is the time that the surface elements are exposed to the surface, and cei(t) and ce(t) are the concentrations of aroma compounds in the interface and emulsion, respectively. (wikipedia.org)
  • Osmotic
  • Consequently, Jv is much less than previously calculated, and the unopposed diffusion of interstitial proteins to the subglycocalix space if and when filtration falls wipes out the colloid osmotic pressure difference necessary for reabsorption of fluid to the capillary. (wikipedia.org)
  • concentration
  • When a chemical species participating in an electrochemical electrode reaction is in short supply, the concentration of this species at the surface decreases causing diffusion, which is added to the migration transport towards the surface in order to maintain the balance of consumption and delivery of that species. (wikipedia.org)
  • equilibrium
  • In all cases, the separation mechanism is borne from differences in particle mobility (electrophoretic, when the field is a DC electric field causing a transverse electric current flow) under the forces of the field, in equilibrium with the forces of diffusion: an often-parabolic laminar-flow-velocity profile in the channel determines the velocity of a particular particle, based on its equilibrium position from the wall of the channel.

  • include
  • The immunoisolation techniques used to date include: extravascular diffusion chambers, intravascular diffusion chambers, intravascular ultrafiltration chambers, microencapsulation, and macroencapsulation. (google.com)
  • Techniques that help in minimizing bacterial colony growth within UPW streams include occasional chemical or steam sanitization (which is common in the pharmaceutical industry), ultrafiltration (found in some pharmaceutical, but mostly semiconductor industries), ozonation and optimization of piping system designs that promote the use of Reynolds Number criteria for minimum flow along with minimization of dead legs.
