Lost ear wicks

Management of refractory tympanostomy tube otorrhea with ear wicks.

INTRODUCTION Tympanostomy tube placement is one of the most common surgical procedures performed in children. Approximately 1 million tympanostomy tube placement procedures are performed on a yearly basis in the United States. The literature reports varying rates of postoperative tympanostomy tube otorrhea, ranging from 1.7% to 83%. Reported rates of recurrent postoperative tube otorrhea are 7....

Parametric verification of one-way lithographic wicks

An asymmetric gap was fabricated into a dense array of medium-high carbon nanotubes to achieve a one-way fluid transport device through capillary action.

Effect of fabrication parameters on thermophysical properties of sintered wicks

Porous wicks for use in a loop heat pipe were sintered from copper and Monel powder. These wicks were characterized in terms of their shrinkage, porosity, thermal conductivity, liquid permeability and maximum capillary pressure. The effect of fabrication parameters (particle size and sintering conditions) on these properties was studied. Shrinkage was found to increase with increasing sintering...

Lost iPhone? Lost Passwords!

The paper highlights risks that accompany losing a locked iOS device regarding confidentiality of passwords stored in the keychain. It presents results of handson tests that show the possibility for attackers to reveal some of the keychain entries. For the described approach, the knowledge of the user’s secret passcode is not needed, as the protection provided by the passcode is bypassed.
