ROMÃO3 1 Thermal and Fluids Engineering Department, Mechanical Engineering Faculty, State University of Campinas, Campinas/SP, It is an example of a simple numerical method for solving the Navier-Stokes equations. It contains fundamental components, such as discretization on a staggered grid, an implicit viscosity step, a projection step, as well as the visualization of the solution over time. The main priorities of the code are 1.

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.

The disk-diffusion agar method tests the effectiveness of antibiotics on a specific microorganism. An agar plate is first  Stokes method; Etest (also based on antibiotic diffusion); Agar and Broth dilution methods for minimum inhibitory concentration (MIC) determination.

Comparison of the modified Stokes' method of susceptibility testing with results obtained using MIC methods and British Society of Antimicrobial Chemotherapy breakpoints Stokes' disc diffusion

The Navier-Stokes equations of fluid dynamics in three-dimensional, unsteady form. could, in theory, be solved for a given flow problem by using methods from calculus. Diffusion is related to the stress tensor and to the viscosity of the gas. expressions for the diffusion coefficient can be obtained using methods from the obtained using the Stokes-Einstein equation for the diffusivity,. D = kT. 3πµd. The disc diffusion method was to be used to test the effects of the spices on E. faecalis. Sterile discs were to be soaked in filtered, autoclaved extracts of each  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.
