Malignant tumors of the nasal cavity are rare. We report the case of an elderly woman who consulted us with a 4-year history of progressive nasal obstruction, occasional epistaxis, facial pain, and watering of the eyes. A diagnosis of olfactory neuroblastoma was established by histopathology and confirmed by immunohistochemistry. On staging, the mass was classified as a Kadish stage B tumor. Th...

A 24 years old lady presented with classical history of acute intestinal obstruction. There was a background history of chronic abdomen for 9 years. There was asymmetrical abdominal distension. On laparotomy, the entire small intestine was cocooned and enclosed in a yellowish white thick fibrotic membrane resulting in obstruction of the small intestine. When the membrane was carefully peeled of...

This study was undertaken to optimize ethanol vapor application as a ripening inhibitor on whole mangoes to extend fresh-cut mango shelf life. Freshly harvested mangoes were first subjected to hot water (+HW) at 46 ◦C for 60 or 90 min to simulate quarantine heat treatments, or remained untreated (−HW). Fruit of each batch (+ or −HW) were then held at 20–25 ◦C for 4 or 7 d (D4 and D7) after the ...

In this paper, we describe a technique, with roots in topological graph theory, that we call rind modeling. It provides for the easy creation of surfaces resembling peeled and punctured rinds. We show how the method’s two main steps of 1) creation of a shell or crust like the rind of an orange, and 2) opening holes in the crust by punching or peeling can be encapsulated into a real time semi-au...
