Acute dacryocystitis: two cases reports [PDF]
The adult lacrimal obstruction can be congenital or acquired. In the case of the acquired form, the etiology classifies in not-specific (it involves the coating epithelium and/or the vascular plexus submucosae of the lacrimal duct) and specific ...

Abstract Argochampsa krebsi is a gavialoid crocodylian from the early Paleogene of North Africa. Based on its recovered phylogenetic relationship with South American species, it has been inferred to have been capable of transoceanic dispersal, but potential anatomical correlates for a marine lifestyle have yet to be identified.

Inertial migration in dilute and semi-dilute suspensions of rigid particles in laminar square duct flow [PDF]
We study the inertial migration of finite-size neutrally buoyant spherical particles in dilute and semi-dilute suspensions in laminar square duct flow. We perform several direct numerical simulations using an immersed boundary method to investigate the effects of the bulk Reynolds number $Re_b$, particle Reynolds number $Re_p$ and duct to particle size

Adenocarcinoma of the lacrimal gland: a case report
Background Primary ductal adenocarcinomas of the lacrimal gland are very rare. This neoplasm shares some histological and immunohistochemical similarities with salivary duct carcinoma.

Chronic dacryocystitis and its ayurvedic management
Chronic dacryocystitis is a chronic infection of the lacrimal sac. In chronic dacryocystitis, there is obstruction of the nasolacrimal duct at the junction of lacrimal sac followed by stasis in the lacrimal sac, causing watering and discharge from the ...

Uniqueness of Transonic Shock Solutions in a Duct for Steady Potential Flow [PDF]
We study the uniqueness of solutions with a transonic shock in a duct in a class of transonic shock solutions, which are not necessarily small perturbations of the background solution, for steady potential flow. We prove that, for given uniform supersonic upstream flow in a straight duct, there exists a unique uniform pressure at the exit of the duct ...

Inertial particle focusing in fluid flow through spiral ducts: dynamics, tipping phenomena and particle separation [PDF]
Small finite-size particles suspended in fluid flow through an enclosed curved duct can focus to points or periodic orbits in the two-dimensional duct cross-section. This particle focusing is due to a balance between inertial lift forces arising from axial flow and drag forces arising from cross-sectional vortices.
