Skin samples that have degraded following excision will have had some of the bound water released, which produces an increase in the for a given temperature, complicating interpretation of the results. In‐vivo skin has a hydration gradient. The outermost layer, the stratum corneum, varies in ...
formula [英][ˈfɔ:mjələ][美][ˈfɔ:rmjələ]n.公式，准则; 客套话; 方案; 婴儿食品;复数：formulasformulae 双语例句 The combined effect of uplift and denudation upon the temperature gradient can be obtained by formula ( 3.86).抬升...
Q/t = kA((T1-T2)/l), where Q/t is the rate of heat transfer, k is the thermal conductivity of the material, A is the cross-sectional area, T1-T2 is the temperature difference, and l is the thickness. How do you calculate heat transfer? To calculate the rate of heat transfer, ...

The higher the temperature T, the slower the decrease of density with altitude. On the other hand, the increase of the force of gravity mg (at a constant temperature) leads to a considerably larger compression of the lower layers and to an increase of the pressure drop (gradient). The gra...
The source, makeup as well as the quantity of these nutrients are important in overall development of the infant, and can act locally in regulating the maturation of the intestine and the makeup of the gut microbes that colonize the neonate's GI tract1–3. Using rodent and avian models, ...
A concentration gradient across a semi-permeable barrier causes the molecules to travel down the concentration gradient across the barrier. An example of this occurs in a helium balloon left out over multiple days. Helium molecules slowly cross the rubber barrier into the air, and oxygen and ...
the dot is because γ is the shear, and a first derivative (the rate of change) of a variable is often denoted with a dot above the associated variable. Using calculus, the continuous shear rate would be given as dv/dx instead and is also referred to as the velocity gradient. ...
The mobile phases with the same composition were used for the metabolomics analysis of urine and serum samples. The 0.1 % formic acid-water and 0.1 % formic acid-acetonitrile were used as mobile phase A and B, respectively. A modified gradient elution program for serum samples was set...
