Thus, existing design correlations are often valid only for one of the boiling regimes.
What Vanguard says are myths about exchange funds are, in Barclays' view, often valid positions.
In this work, theoretical and experimental evidence is presented to show that a Bruggeman exponent of 1.5 is often not valid for real electrodes or separator materials.
For conventional well testing which is carried out over several days or several weeks, reservoir properties are usually assumed to be constant, but this assumption is often not valid for analyzing long-term transient pressure data acquired from a permanent down-hole gauge, which can record down-hole transient pressure data for several years.
The issue here is not about managing traffic for often-valid technical reasons.
Often the classical Darken theory, valid for stress-free systems with ideal vacancy source and sink activity, is generalized to multicomponent systems with ideal vacancy source and sink activity.
In the proofs of the lemmas we often use the following inequalities valid for the function f vanishing at x = 0 and x = 1 or for the function with the first derivative vanishing at some point x ∈ [ 0, 1 ] : | f | 2 ≤ 2 ∥ f ∥ ∥ ∂ f ∂ x ∥, ∥ f ∥ ≤ 2 ∥ ∂ f ∂ x ∥, (39).
AICPA official Harvey J. Berger wrote the IRS saying there often are valid reasons for these low numbers.
Equation 2 is often modified to Eq. 3 valid for m = 1.
