1. Small lymphocytes in serum at 37 degrees C. migrate toward the anode under experimental conditions described. 2. The electromotive force of 0.8 volt per cm. under the same conditions produced a straight line velocity which approximated that reported by McCutcheon for spontaneous velocity after his preparation had been studied over 5 hours. 3. Keeping the lymphocytes on ice up to 30 hours did...
Abstract. The concept of electromotive force appears in various electromagnetic applications geophysical and astrophysical fluids. A review the its to solar wind are discussed such as profile during shock crossings observational tests for mean-field model against data. is being recognized serving a useful tool construct more complete picture space plasma turbulence when combined with energy spe...
A new method of using photo-electromotive force in detecting gas and controlling sensitivity is proposed. Photo-electromotive force on the heterojunction between porous silicon thin layer and crystalline silicon wafer depends on the concentration of ammonia in the measurement chamber. A porous silicon thin layer was formed by electrochemical etching on p-type silicon wafer. A gas and light tran...
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 action. The contribution of this effect to themean electromotive force is proportional to the production...
