Mean electromotive force proportional to mean flow in MHD turbulence
, 2009
"... In meanfield magnetohydrodynamics the mean electromotive force due to velocity and magneticfield fluctuations plays a crucial role. In general it consists of two parts, one independent of and another one proportional to the mean magnetic field. The first part may be nonzero only in the presence o ..."

Mean Electromotive Force and Dynamo Action in a Turbulent Flow
, 1999
"... . We derive the expression for the mean electromotive force in a turbulent flow taking into account stretching of turbulent magnetic field lines and streamlines by the mean flow. Shear stresses break the symmetry of turbulence in such a way that turbulent motions become suitable for the dynamo actio ..."

EFFECT OF DIFFERENTIAL ROTATION ON NONLINEAR MEAN ELECTROMOTIVE FORCE IN A TURBULENT FLOW
, 2008
"... An effect of a mean differential rotation on the nonlinear mean electromotive force in a turbulent flow is studied. An interaction of the mean differential rotation (i.e., a mean velocity shear) with a smallscale turbulent motions can cause a generation of a mean magnetic field even in a nonhelical ..."

Kron’s Method and Cell Complexes for Magnetomotive and Electromotive Forces
"... Abstract—Starting from topological principles we first recall the elementary ones giving Kirchhoff’s laws for current conservation. Using in a second step the properties of spaning tree, we show that currents are under one hypothesis intrinsically boundaries of surfaces flux. Naturally flux appears ..."

appears as the object from which the edge comes from. The current becomes the magnetomotive force (mmf) that creates the flux in the magnetostatic representation. Using a metric and an Hodge’s operator, this flux creates an electromotive force (emf). This emf is finally linked with the current to give

Critical analysis of various analytical approaches to the mean electromotive force

"... There are various analytical approaches to the mean electromotive force E = 〈u × b 〉 crucial in mean–field electrodynamics, with u and b being velocity and magnetic field fluctuations. In most cases the traditional approach, restricted to the second–order correlation approximation, has been used. It ..."

E LECTRICAL phenomena in oral cavities have been described and discussed in many papers published between 1878 and the present time. Solomon, Reinhard, and Goodale1 abstracted the 24 most important papers published before June, 1933. The papers up to late 1933 describe different cases and suggest explanations of the observed symptoms. Cases are described in which certain pathologic conditions in the oral cavity were relieved when the metallic restorations were changed so that all were made of one kind of metal, or were completely removed. Lain and Caughron2 reported their use of a Weston Model No. 440 microammeter having a range of 75 microamperes, and stated that in only a few cases did they require an instrument having a greater range. They also state correctly that the potential difference of the tw6 restorations could be calculated by taking the product of the observed current and the resistance of the microammeter. They state neither the resistance of the meter nor the magnitude of a potential difference. The chief concerns of the paper are case histories and
