Lacrimal Sac Mucoepidermoid Carcinoma with Metastases to the Cavernous Sinus Following Dacryocystorhinostomy Treated with Stereotactic Radiotherapy

open access: yesCase Reports in Ophthalmology, 2016
Purpose: We report a very good outcome in a 44-year-old woman in whom cancer was missed as the cause of nasolacrimal duct obstruction and dacryocystitis and which was deemed inoperable after spreading to the cavernous sinus.

CFD-based design optimization of a 5 kW ducted hydrokinetic turbine with practical constraints [PDF]

open access: yesarXiv
Ducted hydrokinetic turbines enhance energy-harvesting efficiency by better conditioning the flow to the blades, which may yield higher power output than conventional freestream turbines for the same reference area. In this work, we present a ducted hydrokinetic turbine design obtained by simultaneously optimizing the duct, blade, and hub geometries ...
