potential gradient
31Electrotonic potential — In physiology, electrotonic conduction refers to the passive conduction of current, and can be considered the opposite of saltatory conduction. In order for a neuron to fire, there are two types of electrical potentials produced. The first is a… …
32Velocity potential — A velocity potential is used in fluid dynamics, when a fluid occupies a simply connected region and is irrotational. In such a case,: abla imes mathbf{u} =0,where mathbf{u} denotes the flow velocity of the fluid. As a result, mathbf{u} can be… …
33Adverse pressure gradient — An adverse pressure gradient occurs when the static pressure increases in the direction of the flow. This is important for boundary layers, since increasing the fluid pressure is akin to increasing the potential energy of the fluid, leading to a… …
34PH-Gradient — Ein Protonengradient ist ein Maß für die Steilheit eines Protonen Konzentrationsgefälles. Er gibt die Änderung der Protonen Konzentration, genauer der Konzentration an hydratisierten H+ Ionen (H3O+ oder Oxonium), bezogen auf eine Strecke an. Da… …
35Ph-Gradient — Ein Protonengradient ist ein Maß für die Steilheit eines Protonen Konzentrationsgefälles. Er gibt die Änderung der Protonen Konzentration, genauer der Konzentration an hydratisierten H+ Ionen (H3O+ oder Oxonium), bezogen auf eine Strecke an. Da… …
36Electromagnetic four-potential — The electromagnetic four potential is a covariant four vector defined in volt middot;seconds/meter (and in maxwell/centimeter in parentheses) as:A {alpha} = left( frac{phi}{c}, vec A ight) qquad left(A {alpha} = ( phi, vec A) ight)in which phi is …
37Electric field gradient — Mathematically, the electric field gradient (EFG) is the hessian matrix (the matrix of the second derivatives) of the electrical potential V: :V {ij} = frac{partial^2 V}{partial x i partial x j}It is an important structural property of a… …
38water potential — The chemical potential (ie. free energy per mole) of water in plants. Water moves within plants from regions of high water potential to regions of lower water potential, ie. down gradient …
39magnetic potential — noun : the scalar quantity characteristic of a point in a magnetic field whose negative gradient equals the intensity or strength of the magnetic field and which represents the work required to bring a unit north pole from a point infinitely… …
40Salinity gradient — power or osmotic power is the energy retrieved from the difference in the salt concentration between seawater and river water. Two practical methods for this are Reverse electrodialysis [Power generation by reverse electrodialysis [http://mtg.tnw …
