Low-noise, high-strength, spiral-bevel gears for helicopter transmissions [PDF]
Improvements in spiral-bevel gear design were investigated to support the Army/NASA Advanced Rotorcraft Transmission program. Program objectives were to reduce weight by 25 percent, reduce noise by 10 dB, and increase life to 5000 hr mean-time-between ...

Clinical Oral Implants Research, EarlyView.ABSTRACT Objectives The oral fine motor control is compromised in patients with full‐arch, bimaxillary bridges compared to those with natural teeth. No previous studies have examined the differences between the prosthetic treatments small anterior bridges and single anterior implants (SI). The aim of the study was to evaluate oral fine motor control in

LOADED TOOTH CONTACT ANALYSIS OF SPIRAL BEVEL GEARS CONSIDERING EDGE CONTACT
Chinese Journal of Mechanical Engineering, 2002 openaire +1 more source
Cell Proliferation, EarlyView.This study provides the first definitive identification of tunnelling nanotubes (TNTs) between cultured osteocytes and shows TNT‐mediated lysosome transfer from healthy to stressed cells, restoring autophagic flux and preventing apoptosis. This discovery of transcellular autophagy reveals a new survival mechanism in osteocytes, offering potential ...

Spur-Gear-System Efficiency at Part and Full Load [PDF]
A simple method for predicting the part- and full-load power loss of a steel spur gearset of arbitrary geometry supported by ball bearings is described. The analysis algebraically accounts for losses due to gear sliding, rolling traction, and windage in ...

Dental Traumatology, EarlyView.ABSTRACT Background/Objective 3D printed materials have been evaluated for fabricating mouthguards; however, little is known about their biomechanical performance in preventing dental trauma. This study aimed to compare two 3D printed polymers and three ethylene vinyl acetate (EVA) sheets used for mouthguard fabrication regarding their mechanical ...
