A model-independent reconstruction of mechanical profiles (density, pressure) of the solar interior is outlined using the adiabatic sound speed and bouyancy frequency profiles. These can be inferred from helioseismology if both pand g-mode frequencies are measured. A simulated reconstruction is presented using a solar model bouyancy frequency and available sound speed data. Subject headings: Su...

The gravimetric analysis of total fecal fat by a proposed chloroform extraction procedure has been shown to compare very closely with an accepted procedure involving a petroleum ether extraction, at all levelsof fecal fat. The decrease in the density of the chloroform by the fecal fat is used as a semiquantitative measure of fat concentration. This is accomplishedby noting the bouyancy of the c...

The possible role of magnetic flux tubes in transporting matter from near the H shell through the radiative zone and into the convective envelope is explored. It is shown that the required rates of mass transport necessary to provide nuclear processed material to the envelope can be achieved if large magnetic fields are present just above the H shell in AGB and RGB stars. The required fields in...

In this paper natural convection heat transfer within a two-dimensional, horizontal, concentric cam shape cylinders that is partially filled with a fluid saturated porous medium has been investigated. both cylinder are kept at constant and uniform temperatures with the outer cylinder being subjected relatively lower than the inner one. In addition the forchheimer and brinkman effect are taken i...

Through a study of the van der Waals interaction between a solid and an air-water interface, we investigate the practical and fundamental problem of the limiting height at which an object can approach a free surface. A numerical study of the interface shape reveals dependencies governed by two disparate length scales associated with the relative strengths of the van der Waals and bouyancy force...
