What is detectable depends strongly on the means of illuminating, magnifying, and viewing the film-splitting meniscus deep within the narrow gap between the rolls. The samples were pipetted from underneath the mineral oil to ensure a positive meniscus. On each occasion an unused coverslip was placed over the meniscus and left in place for 5 min before examining for eggs. The origin is the centre of curvature of the undisturbed meniscus. The image is not a line segment because the curvature of the meniscus perpendicular to the roll axis spreads the narrow sheet of light. Subsequently, samples were allowed to settle for at least 15 min during which eggs migrated to the top of the meniscus. The flotation fluid in each centrifuge tube was topped up ten times to form a positive meniscus. The normal-stress iterative scheme used to determine the meniscus profile is as follows. First a profile of the meniscus is chosen, either by an informed guess or on the basis of the previous iterations. The critical speeds determined experimentally for a receding meniscus in a tube are considerably smaller than those obtained here for a meniscus in a channel. The results presented here determine the critical speed for the validity of these solutions for a plate and a meniscus in a channel. In this solution, the meniscus extends from the contact line to form a sheet with a free surface parallel to the plate. In these examples, only the wedge (meniscus) angle 0 changes; all of the parameters are fixed. The biofilm was below the meniscus of the culture medium, which exerted a positive pressure on the biofilm. See all examples of meniscus These examples are from corpora and from sources on the web.
