quasi-equilibrium

quasi-equilibrium

[¦kwä·zē ‚ē·kwə′lib·rē·əm]
(geology)
The state of balance or grade in a stream cross section, whereby conditions of approximate equilibrium tend to be established in a reach of the stream as soon as a rather smooth longitudinal profile has been established in that reach, even though downcutting may go on.

The chapters address theories of baroclinic adjustment and eddy equilibrium, thermal stratification of the extratropical troposphere, storm track dynamics, eddy-mediated interactions between low latitudes and the extratropics, quasi-equilibrium dynamics of the tropical atmosphere, simple models of ensemble-averaged tropical precipitation and surface wind, dynamical constraints on monsoon circulations, moist dynamics of tropical convection zones in monsoons and global warming, challenges in numerical modeling of tropical circulations, and challenges to the understand of general circulation and abrupt climate change.
The data show that the hmAb m610, which recognizes the mature and the premature forms of IGF-II, is most extensively characterized and was evaluated in an in vivo MCF-7 cell-based mouse xenograph model to test the hypothesis that high levels of soluble ligand-specific antibody in the blood could shift the quasi-equilibrium distribution of the ligand between the blood and the tumor resulting in a decreased ligand concentration in the tumor.
On the other hand, a disadvantage of our system is the local measurement (given by position of laser trace) of the mean value of a displacement at quasi-equilibrium conditions.
When annealed epoxy glass is subjected to large deformations, the thermodynamic state of epoxy glass changes from a quasi-equilibrium state to a non-equilibrium state [1], and the stress relaxation behavior of largely deformed epoxy glass is nonlinear viscoelastic.
A direct detection limit of ~2 [micro]g/L has already been demonstrated, whether measured in terms of the initial rate (<5 min) or at quasi-equilibrium (30-60 min), a phase response of 0.
p], T) function is replaced by the quasi-equilibrium stress which depends on both the strain and temperature as follows:
A minimum of 600 s operation after any screw speed adjustment was used to achieve quasi-equilibrium before recording temperature variations in the extruder throat using a Hewlet-Packard multi-channel recorder.
where the quantity [[Sigma] - g([Epsilon])] is the deviation of the current stress [Sigma] from the quasi-equilibrium value at strain [Epsilon]; [[Sigma] - g([Epsilon])] is called on an overstress; g([Epsilon]) is a quasi-equilibrium stress obtained from a stress-strain curve at a strain rate of [Mathematical Expression Omitted]; and K([Sigma], [Epsilon]) is the viscosity function.
