Experimental observations show that a strong magnetic field has a dramatic influence on the sedimentation of RBCs, which motivates us to model the sedimentation of red blood cell (RBC) under strong external magnetic body force. To model the sedimentation of a RBC in a square duct and a circular pipe, a recently developed technique derived from the lattice Boltzmann and the distributed Lagrange ...

In the paper the results of experimental studies on the sedimentation process of barium carbonate (of mean particles diameter of 25 [μm]) in aqueous solutions of tetradecyltrimethylammonium bromide, have been presented. As the additives assisting in micellar association the sodium bromide and sodium salicylate, have been used. The sedimentation tests were carried out in the transparent cylinder...

Theories concerning the concentration-dependence of sedimentation and diffusion coefficients for macro-molecules in dilute solution are compared and discussed, together with their experimental basis. An attempt has been made to clarify an important uncertainty still present in the literature as to whether sedimentation coefficients should be corrected for solvent or solution density. It is poin...

Sedimentation. This was observed in a Svedberg oilturbine ultracentrifuge by the method of Cecil & Ogston (1948). The hydrochlorides were dissolved in 0-2M-NaCI to a concentration of 1 g./100 ml. Owing to the relatively small molecular weights and high diffusion coefficients, clear sedimentation boundaries were not obtained; the sedimentation constants were therefore measured bythe method ofGut...

OBJECTIVE To evaluate the usefulness of various magnetic resonance imaging (MRI) findings in the prognosis of neurological recovery in paraplegics with thoracolumbar fracture using association analysis with clinical outcomes and electrodiagnostic features. METHODS This retrospective study involved 30 patients treated for paraplegia following thoracolumbar fracture. On axial and sagittal T2-we...

The gonadotropin receptors associated with plasma membrane fractions were solubilized by detergents, including Triton X-100, Lubrol WX, Lubrol PX and sodium deoxycholate before and after equilibration with 125I-labelled human chorionic gonadotropin. The binding activity remained in solution even after centrifugation at 300 000 X g for 3 h. The solubilized gonadotropin receptor or gonadotropin r...

Descriptions of some thermodynamic properties and transport behavior in solution of an intact multiple myeloma yG-globulin and of one of the products of its reaction with mercaptoethylamine have been provided. For the sedimentation equilibrium experiments, the parent yG-globulin was dissolved in three solvent systems: cacodylate buffer, its 8 M urea solution and its 6 M guanidine hydrochloride ...

OBJECTIVE Erythrocyte sedimentation rate (ESR) may serve as a reasonably good indicator for coronary heart disease as usually ESR is elevated in these patients. The measurement of ESR is a very simple and cheap laboratory test that can be performed in routine blood examinations. In this study, we investigated the association between preoperative erythrocyte sedimentation rate and postoperative ...
