The physiological role of the beta-cell insulin receptor is unknown. To evaluate a candidate function, the insulin regulation of fluid-phase pinocytosis was investigated in a clonal insulinoma cell line (beta TC6-F7) and, for comparison, also in Chinese hamster ovary cells transfected with the human insulin receptor (CHO-T cells). In CHO-T cells, the net rate of fluid-phase pinocytosis was rapi...

We calculate the phase behavior of hard spheres with size polydispersity, using accurate free energies for the fluid and solid phases. Cloud and shadow curves are found exactly by the moment free energy method, but we also compute the complete phase diagram, taking full account of fractionation. In contrast to earlier, simplified treatments we find no point of equal concentration between fluid ...

A recently proposed connection between the threshold for the stability of the iterative solution of integral equations for the pair correlation functions of a classical fluid and the structural instability of the corresponding real fluid is carefully analyzed. Direct calculation of the Lyapunov exponent of the standard iterative solution of hypernetted chain and Percus-Yevick integral equations...

We explore a computational model of an incompressible fluid with a multi-phase field in three-dimensional Euclidean space. By investigating an incompressible fluid with a two-phase field geometrically, we reformulate the expression of the surface tension for the two-phase field found by Lafaurie, Nardone, Scardovelli, Zaleski and Zanetti (J. Comp. Phys. 113 (1994) pp.134-147) as a variational p...

introduction more than 30 fluorite occurrences with approximately 1.35 million tons of reserves have been recognized in iran (ghorbani, 2013). the atashkuh fluorite-barite (±sulfide) deposit is one of four occurrences located south of the city of delijan in markazi province, about 80 km se of arak city. the atashkuh deposit occurs between the central iran structural zone on the north and the sa...

finding a representative fluid in a hydrocarbon reservoir is crucial for integrated reservoir management. in this study, a systematic approach for screening and selecting consistent fluid samples in a reservoir was developed. the model integrated quality control (qc) of well conditioning before sampling, qc of pvt data, thermodynamic modeling and compositional gradient within a reservoir. well ...

Rotational and vibration-rotational Raman spectra of fluid hydrogen (H2) at room temperature were investigated through spectroscopy under pressure. All the rotational lines showed rapid pressure changes in shifts around 0.56 GPa. The peak analyses revealed that ortho-para conversion H2 was generated beyond GPa temperature. Supposedly, anomalies obtained corresponded to a phase transition phase,...
