We are interested in a model for diphasic fluids in thin flows taking into account both the hydrodynamical and the chemical effects at the interface between the two fluids. A limit problem in “thin films” is introduced heuristically. It is a system coupling the Reynolds equation and the hydrodynamical Cahn-Hilliard equation. We study the mathematical properties of this system, and prove an exis...

T HERHYTHMICACTIVITY of thestomach is associated with action potentials which are similar to those of other visceral muscles, including the heart (I). In the work reported here, these potentials were further analyzed by recording monophasic potentials and by leading off separately from longitudinal and circular muscles. Also the action of some drugs was investigated. The fact that monophasic po...

– Considering recent results revealing the existence of multi-scale rigid clusters of grains embedded in granular surface flows, i.e. flows down an erodible bed, we describe here the surface flows rheology through a non-local constitutive law. The predictions of the resulting model are compared quantitatively to experimental results: The model succeeds to account for the counter-intuitive shape...

In space during functioning, a satellite will be heated up due to the behavior of its components such as power electronics. In order to prevent problems in the satellite, this heat has to be released in space thanks to the cooling system. This system consists of a loop heat pipe (LHP), in which a fluid streams through an evaporator and a condenser. In the evaporator, the fluid captures the heat...

Coupled multiphase flow and geomechanics models are computationally costly and complex to implement. In order to take advantage of petascale and future exascale computing power, parallel domain decomposition offers an opportunity for decoupling realistic subsurface problems. The basic idea is to reduce the complexity of these multiphysics problems by applying the coupling only in those domains ...

Visually evoked potentials and background EEGs in the cerebral visual, somatosensory, and association areas (lateral suprasylvian gyrus), as well as in the lateral geniculate body (GL) and mesencephalic reticular formation were studied before and after unilateral destruction of the GL of unanes-thetized cat. Autocorrelograms and power spectra of background EEGs in various areas mainly showed ac...

The bacteriological study of the nasopharyngeal, throat, per nasal tracheal aspirate, and percutaneous lung aspirate was non-contributory, and virological examinations failed to yield a viral agent. Meanwhile the child received treatment with penicillin and streptomycin for 8 days. She became afebrile on 7th day of hospitalization, and her respiratory findings, adenopathy and splenomegaly disap...
