The Smoluchowski coagulation-diffusion PDE is a system of partial differential equations modelling the evolution in time of mass-bearing Brownian particles which are subject to shortrange pairwise coagulation. This survey presents a fairly detailed exposition of the kinetic limit derivation of the Smoluchowski PDE from a microscopic model of many coagulating Brownian particles that was undertak...

The aggregation of four polystyrene latexes with similar surface charge and different diameter has been examined by small angle light scattering. The DLVO model including aggregation at the secondary minimum qualitatively agrees with the experimental dependence of colloidal stability on particle size. Repeptization experiments, where the flocs were redispersed by washing away the coagulating sa...

Nasal obstruction is a frequent disorder that interferes with the daily patient’s quality of life. The key element in pathophysiology inferior turbinate hypertrophy related to multiple conditions such as allergic rhinitis (AR). Many patients are managed using conventional drug therapies antihistamines, decongestants, and intranasal steroid sprays, anticholinergic agents, mast cell stabilizers, ...

Studies inquiring into the mechanism of blood clotting have been made by many careful investigators, and while much is written regarding the factors concerned, there is offered as yet no satisfactory and uniformly accepted explanation for t.he fact that blood usually clots when it escapes from a wound. Some of this confusion exists, perhaps, because the more recent investigations in colloidal c...
