T HE SEPARATION of morphologically distinct cells by differences in their specific gravity has been demonstrated using density gradient centrifugation in several support media. From bovine serum albumin density gradient centrifugation experiments, morphologically similar lymphocytes have been shown to consist of several closely spaced, discontinuous, discrete populations.5 In addition, erythroc...

In the title mol-ecule, C(24)H(18)INO(6)S, the heterocyclic thia-zine ring adopts a half-chair conformation, with the S and N atoms displaced by 0.381 (5) and -0.449 (5) Å, respectively, from the plane formed by the remaining atoms in the ring; the puckering parameters are Q = 0.550 (2) Å, θ = 61.7 (2)° and ϕ = 31.4 (3)°. The conformation is stabilized by an intra-molecular O-H⋯O hydrogen bond....

A feature of stability diagrams of liquid bridges between unequal disks subjected to small axial gravity forces is that, for each separation of disks, there is a value of microgravity for which an absolute minimum volume limit is reached. The dependence of such microgravity values on the liquid bridge geometry has been experimentally checked by using the neutral buoyancy technique, experimental...

A homogeneous thin plate often flutters while falling through a fluid under gravity. The center of gravity of the plate moves back-and-forth horizontally and the plate tilting angle oscillates symmetrically from the horizontal. Here we show that such a scenario is qualitatively changed for a plate with noncoinciding centers of gravity and buoyancy due to an inhomogeneous mass distribution. Mism...

One of the factors which affects the gas lift performance is specific gravity of a lift gas (or the Molecular weight), which can influence the gas solubility in oil and has a direct effect on the gas lift performance. There are some previous researches which have included the lift gas specific gravity in their modeling, but in none of them, a comprehensive research about the effect of lift gas ...

We present the first theoretical treatment that accounts in detail for a recent observation of overlapping Bose-Einstein condensates of two different 87Rb hyperfine states [C. J. Myatt et al., Phys. Rev. Lett. 78, 586 (1997)]. Despite the complicated geometry, we have completed a threedimensional Hartree-Fock calculation for the coupled condensates. The calculation explains a number of its key ...

This study considers an operation of an auditory spectral integration process which may be involved in perceiving dynamic time-varying changes in speech found in diphthongs and glide-type transitions. Does the auditory system need explicit vowel formants to track the dynamic changes over time? Listeners classified diphthongs on the basis of a moving center of gravity (COG) brought about by chan...

We present a dynamic van der Waals theory. It is useful to study phase separation when the temperature varies in space. We show that, if heat flow is applied to liquid suspending a gas droplet at zero gravity, a convective flow occurs such that the temperature gradient within the droplet nearly vanishes. As the heat flux is increased, the droplet becomes attached to the heated wall that is wett...

A solution to an equilibrium of irrotational binary polytropic stars in Newtonian gravity is expanded in a power of epsilon = a(0)/R, where R and a(0) are the separation of the binary system and the radius of each star for R = infinity. For the polytropic index n = 1, the solutions are given almost analytically up to order epsilon(6). We have found that in general an equilibrium solution should...
