Stokes’ Law is a proposition that relates the drag force experienced by a falling sphere to the sphere’s (constant) velocity in a liquid of known viscosity.

    The conductivity of brain tissue is an important parameter in EEG/MEG research. A new method was proposed for getting these parameters from the view of electrochemistry based on diffusion tensor imaging (DTI) using Stokes-Einstein and Nernst-Einstein equations. According to Stokes’ law, a perfect sphere traveling through a viscous liquid feels a drag force proportional to the frictional coefficient. The diffusion coefficient D of a sherical particle istproportional to its mobility: Substituting the frictional coefficient of a perfect sphere from Stokes’ law by liquid's viscosity and sphere's radius we have Stokes-Einstein equation. The earliest and still the most widely applied numerical method for the incompressible Navier-Stokes equations is based on splitting the PDE system into simpler components for which we can apply standard discretization methods. Such a strategy is known as operator splitting.

        Stokes Disc Diffusion Technique varies from Kirby Bauer disc diffusion in the use of both control and test strain on a same plate. Stokes disc diffusion technique is not as highly standardized as the Kirby-Bauer technique and is used in laboratories particularly when the exact amount of antimicrobial in a disc cannot be guaranteed due to Abstract. The majority of clinical microbiology laboratories in the UK use comparative disc diffusion methods based on the Stokes' method to determine antibiotic susceptibility. The technical validity of the results obtained from the modified Stokes' method of disc testing and how they relate to MIC data are not known. In fact neglecting the convection term, incompressible Navier–Stokes equations lead to a vector diffusion equation (namely Stokes equations), but in general the convection term is present, so incompressible Navier–Stokes equations belong to the class of convection–diffusion equations. Stoke’s law was established by an English scientist Sir George G Stokes (1819-1903). When a spherical body moves down through an infinite column of highly viscous liquid, it drags the layer of the liquid in contact with it. As a result, the body experiences a retarding force. Then according to Stokes law, the viscous drag force, Stokes’ Law is only valid for non-turbulent flow, so Reynolds number for the falling ball viscometer was also determined.

The results of the test are reported on the antibiogram.

Chapter 7 The Diffusion Equation The diffusionequation is a partial differentialequationwhich describes density fluc-tuations in a material undergoing diffusion. The equation can be written as: to the method (7.12), the amplification factor g(k) can be found from (1+α)g2 −2gαcos(k x)+(α−1)=0. 14.2.4 Disc diffusion method. Disc diffusion or the Kirby–Bauer test is one of the classic microbiology techniques, and it is still very commonly used. Because of convenience, efficiency, and cost, the disc diffusion method is probably the most widely used method for determining antimicrobial resistance around the world. Stokes’ Law is only valid for non-turbulent flow, so Reynolds number for the falling ball viscometer was also determined. Background and Theory. 1. Stokes’ Law and Reynolds Number. Stokes’ Law is a proposition that relates the drag force experienced by a falling sphere to the sphere’s (constant) velocity in a liquid of known viscosity. For the Stokes equations with convection and the incompressible Navier–Stokes equations, the authors analyze a streamline diffusion finite element method that is capable of balancing both the convection and the pressure, thus allowing the use of arbitrary pairs of velocity-pressure spaces.
