INTRODUCTION Incomplete punctal canalization is an uncommon congenital disorder characterized by a dysgenetic punctum with membranes. External membranes, the most common type of incomplete punctal canalization are flat and overlie the punctum as a veil. We describe a newer variant of incomplete punctal canalization, its clinical profile, diagnostic criteria and management. CASE PRESENTATION A...

Culture flasks capped with stainless-steel closures became contaminated when incubated in circulating air. Cotton plugs prevented this contamination.

Flowing through porous media is a matter of interest in different research fields such as medicine, engineering and science. The spontaneous appearance ionic distribution at the solid liquid interface gives place to reduction flow rate, which generally named electroviscous effect. However, this should be differentiated two more specific effects, primary effect due distortion clouds, secondary o...

In this work we assessed the strength and stiffness of high low porosity outcrop chalk plugs saturated with three different fluids. Plugs were triaxially tested in a Hoek cell at varying confining stress to probe parts failure envelope as described p-q’ space (brittle, transition yield modes). Stiffness was derived from bulk density P S-wave ultrasonic velocities measured throughout mechanical ...

Fluidized beds are suspensions of grains by ascending fluids in tubes, and commonly used industry given their high rates mass heat transfers between the solids fluid. Although usually employed large scales (tube diameter order meter), fluidized have a great potential much smaller (order millimeter) for processes involving powder fluids. Of particular interest is pharmaceutical industry, which c...

We studied the self-assembly of inorganic nanocrystals (NCs) confined inside nanoliter droplets (plugs) into long-range ordered superlattices. We showed that a capillary microfluidic platform can be used for the optimization of growth conditions for NC superlattices and can provide insights into the kinetics of the NC assembly process. The utility of our approach was demonstrated by growing lar...

Sialodochitis fibrinosa (or commonly known as Kussmaul Disease) is a rare salivary gland disease characterized by recurrent salivary gland swelling and pain as a result of mucofibrinous plugs. Typically patients have a history of multiply recurrent glandular swelling, dehydration and/or decreased salivary flow, thick secretions from Stensen's or Wharton's duct, and/or history of allergic diseas...
