Whole-cell patch-clamp recordings allow diffusible intracellular ions and molecules to be replaced by the contents of the recording pipette. In this review, the formulation of intracellular media is considered with a view to improving the stability of recordings and emulating the intracellular environment. In electromagnetic fluctuation theory two methods are frequently used: (i) linear response theory and fluctuation-dissipation-theorem, (ii) Langevin-theory. In this note the two methods are compared. The equivalence of both methods is shown. An extension of the second method to describe dynamical processes (radiative heat transfer) in inhomogeneous systems cannot be justified rigorously. The near point of accommodation was determined in four cats by measuring visual acuity at viewing distances varying from 125 to 12 cm. The near point of accommodation was taken as the closest viewing distance which just produced a decrement in grating acuity. The values obtained ranged from 25 to 36 cm and are in good agreement with physiological and optical estimates of the near point of accommodation. While Georgescu-Roegen's assertion that the Air Jordan High Heels Canada “complete recycling Nike Jordans Canada of matter is impossible” cannot be proven by thermodynamic considerations alone, it is supported by mass transfer rate theory.
