constructing phase diagram and its subsequent quality lines for lean gas condensate reservoirs is always crucial and challenging topic in reservoir fluid studies. due to small amounts of liquid drop-outs in lean gas condensates at reservoir conditions, full experimental tracking of phase diagram and its relevant quality lines is almost impossible for lean gas condensates.on the other hand, eos ...

We study experimentally the line of a single quantized vortex in a rotating prolate Bose-Einstein condensate confined by a harmonic potential. In agreement with predictions, we find that the vortex line is in most cases curved at the ends. We monitor the vortex line leaving the condensate. Its length is measured as a function of time and temperature. For a low temperature, the survival time can...

certain gases, principally oxygen,o , and carbon dioxide, co , dissolved in water accelerate its corrosive properties. the rate of corrosion is approximately in prportion to the quantity of gas dissolved. the removal of gases from water, as practiced in steam station, is effected by mechanical and thermal treatment , by addition of chemicals, or by combinations of these processes, the most wide...

So this small package arrives at my office, addressed to “Anniken Goldstein.” Two Goldsteins work in my office, my Bride/Empress and myself, so she took the liberty of opening it up, and extracting a Darth Vader head coffee cup from a carefully bundled straw package. There was no accompanying note; the return address indicated that none was needed. Everyone from my receptionist to my office man...

Although two-phase flow is frequently encountered in various location of the process plants, there is no a general accepted and verified two-phase flow model that may be used to size lines for such conditions. An obvious example is condensate water return lines. The API method that used in this study is based on the homogeneous equilibrium flow assumption, that is, equal velocity and equal temp...

Stimulated small-angle light scattering was used to measure the structure factor of a Bose-Einstein condensate in the phonon regime. The excitation strength for phonons was found to be significantly reduced from that of free particles, revealing the presence of correlated pair excitations and quantum depletion in the condensate. The Bragg resonance line strength and line shift agreed with predi...

State-selected rubidium-87 molecules were created at rest in a dilute Bose-Einstein condensate of rubidium-87 atoms with coherent free-bound stimulated Raman transitions. The transition rate exhibited a resonance line shape with an extremely narrow width as small as 1.5 kilohertz. The precise shape and position of the resonance are sensitive to the mean-field interactions between the molecules ...
