The evaporation of a sessile droplet liquid is complex and multifaceted fundamental topic enduring scientific interest that key to numerous physical biological processes. As result, in recent decades considerable multidisciplinary research effort has been directed toward many different aspects the problem. This review focuses on some insights can be obtained from relatively simple mathematical ...

We study the dynamics and arrest of two coalescing sessile yield-stress drops. Surprisingly, we find that height bridge evolves similar to a Newtonian fluid. The arrested final coalesced shape is described by balance between capillary pressure yield stress, which predicted from viscoplastic lubrication theory.

The onset of Marangoni convection for evaporating liquids Brendan D. MacDonald Doctor of Philosophy Graduate Department of Mechanical and Industrial Engineering University of Toronto 2012 The stability of evaporating liquids is examined. The geometries investigated are semiinfinite liquid sheets, bounded liquid sheets, sessile droplets, and funnels. Stability parameters are generated to charact...

our primary objective was to measure root canal penetrations of aqueous antibacterial nano-chitosan (nano-cs), for the first time. the second objective was to compare and contrast such penetrations to those of chitosan (cs) itself, as well as sodium hypochlorite (naocl), chlorhexidine (chx) and ethylenediamintetraacetic acid (edta), at the routinely used concentrations. molar roots were split l...

BACKGROUND When endoscopic retrograde cholangiopancreatography (ERCP) guided bile duct biopsy fails to demonstrate malignancy, it remains unclear how to manage patients with presumably malignant strictures. AIMS To evaluate the value of intraductal ultrasonography (IDUS) when bile duct biopsy is negative. METHODS Sixty two patients with strictures of the bile duct were studied prospectively...

Factor IX Chicago-2 and prothrombin Madrid were purified from patients with hemophilia B and congenital dysprothrombinemia. respectively. Each protein displays defects in zymogen activation secondary to the failure to cleave one of the sessile bonds whose cleavage is necessary for full coagulant activity. These proteins were isolated by immunoaffinity chromatography using conformation-specific ...
