Suspensions of aerobic bacteria often develop flows from the interplay of chemotaxis and buoyancy. We find in sessile drops that flows related to those in the Boycott effect of sedimentation carry bioconvective plumes down the slanted meniscus and concentrate cells at the drop edge, while in pendant drops such self-concentration …

Concentration Gradient Definition. Concentration gradient refers to the gradual change in the concentration of solutes in a solution as a function of distance through a solution. A solution, essentially, has two major components, the solvent (the dissolving component, e.g. water) and the solute (the particles that are dissolvable by …

Gravity concentration is a general term designating processes for separating and sorting granular material by means of forces that depend on the density, size and shape of the particles. When these forces are applied to the particles the latter are caused to move, those of a given density along one path and those of a different density …

The microstructure and mechanical properties of Al-8.1Mg-2.6Si-(0.08 to 4.62)Zn alloys (in wt pct) have been investigated by the permanent mold casting process. X-ray diffraction analysis shows that the τ-Mg32(Al, Zn)49 phase forms when the Zn content is 1.01 wt pct. With higher Zn contents of 2.37 and 3.59 wt pct, the η-MgZn2 and τ …

The acceleration due to gravity is the net acceleration that an object close to Earth's surface experiences due to the combined effect of the gravitational force and the centrifugal force.It is denoted by the letter 'g'. The numerical value of g is 9.81 m/s 2.There are slight variations of this value depending on a few factors.
