Annular honeycomb seals: Test results for leakage and rotordynamic coefficients; comparisons to labyrinth and smooth configurations [PDF]
Test results are presented for leakage and rotordynamic coefficients for seven honeycomb seals. All seals have the same radius, length, and clearance; however, the cell depths and diameters are varied.

Sex‐specific acceleration of Alzheimer's pathogenesis by chronic sleep‐deprivation
Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.Abstract INTRODUCTION Sleep impairments likely contribute to Alzheimer's pathology, though specific contributions to disease progression are incompletely understood. We propose that autophagic impairment is associated with chronic sleep disruption and examine how sleep loss and stress influence disease development, including having impacts on ...

Numerical and experimental investigation on uniformity of pressure loads in labyrinth seal
Advances in Mechanical Engineering, 2017 The pressure loads acting on the teeth of a labyrinth seal could differ significantly. Sometimes, one of the teeth would take almost half of the total pressure difference.

The Current Situation and Development of Endoscopic Ear Surgery in China
World Journal of Otorhinolaryngology - Head and Neck Surgery, Volume 12, Issue 1, Page 136-143, February 2026.ABSTRACT Endoscopic ear surgery has been widely performed in China since 2015 due to the development and rapid popularization of endoscopic technology. Due to the relative shortness of the auditory meatus, only a fixed endoscope is required in many cases, rather than a motion similar to a nasal endoscope, and uncontrollable bleeding is virtually non ...

Continued Investigation of Leakage and Power Loss Test Results for Competing Turbine Engine Seals [PDF]
Secondary seal leakage in jet engine applications results in power losses to the engine cycle. Likewise, seal power loss in jet engines not only result in efficiency loss but also increase the heat input into the engine resulting in reduced component ...
