Effects of buoyancy and of magnetic forces on osmotic pressure.
The commonly held view that the mechanism of osmotic pressure is a mass action effect at the semi-permeable membrane has recently been challenged by several authors who propose that solute molecules, in bombarding the free surface of the solution, subject the solvent to a negative hydrostatic pressure. Thus, they argue that osmotic pressure is a purely hydrostatic phenomenon. Experimental findi...
متن کاملManipulating Microrobots Using Balanced Magnetic and Buoyancy Forces
We present a novel method for the three-dimensional (3D) control of microrobots within a microfluidic chip. The microrobot body contains a hollow space, producing buoyancy that allows it to float in a microfluidic environment. The robot moves in the z direction by balancing magnetic and buoyancy forces. In coordination with the motion of stages in the xy plane, we achieved 3D microrobot control...
متن کاملBuoyancy and Strength
The chief characteristic of presuppositions is that they tend to take wide scope, yet most theories of presupposition, the author's not excepted, fail to provide an explanation of this fact. Recently, however, it has been suggested that a principled explanation can be given in terms of informativeness: the idea is that presuppositions simply prefer stronger readings to weaker ones. This proposa...
متن کاملThe Presence of Buoyancy
Laminar natural convection flow and heat transfer of a viscous incompressible fluid confined between two long vertical wavy walls has been analysed taking the fluid properties constant and variable. In particular, attention is restricted to estimate the effects of viscous dissipation and wall waviness on the flow and heat transfer characteristics. Use has been made of a llnearlzatlon technique ...
متن کاملCasimir Buoyancy
We study the Casimir force on a single surface immersed in an inhomoge-neous medium. Specifically we study the vacuum fluctuations of a scalar field with a spatially varying squared mass, m 2 + λ∆(x − a) + V (x), where V is a smooth potential and ∆(x) is a unit-area function sharply peaked around x = 0. ∆(x − a) represents a semi-penetrable thin plate placed at x = a. In the limits {∆(x−a) → δ(...
