A computer solution for the dynamic load, lubricant film thickness and surface temperatures in spiral bevel gears [PDF]
A complete analysis of spiral bevel gear sets is presented. The gear profile is described by the movements of the cutting tools. The contact patterns of the rigid body gears are investigated. The tooth dynamic force is studied by combining the effects of

Chinese Guidelines for the Diagnosis and Surgical Treatment of Adult Obstructive Sleep Apnea (2024)
World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Obstructive sleep apnea (OSA) is a common chronic disorder characterized by abnormal breathing during sleeping. OSA can damage various organs throughout the body and is burdensome, both socially and economically. Moreover, as OSA has been increasingly studied in recent years, new evidence‐based guidelines for its diagnosis and surgical ...

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 ...

Feeding Management of African Rhinos (Ceratotherium simum, Diceros bicornis) in European Zoos
Zoo Biology, EarlyView.The average estimated diets (in % dry matter) of white rhinos (C. simum) and black rhinos (D. bicornis) in European zoos differ in the proportion of (pelleted) compound feed and other non‐forage items. The reason for this difference is elusive but possibly related to creating more complicated diets for browsers. ABSTRACT White rhinos (WR, Ceratotherium

Journal of Forensic Sciences, EarlyView.Abstract Saw mark analysis is an important component of forensic anthropology, particularly in cases of postmortem dismemberment. While stereomicroscopy remains the benchmark for evaluating kerf features, recent advances in imaging technologies offer new opportunities for documenting and interpreting bone trauma.

Tooth Contact Shift in Loaded Spiral Bevel Gears [PDF]
An analytical method is presented to predict the shifts of the contact ellipses of spiral bevel gear teeth under load. The contact ellipse shift is the motion of the tooth contact position from the ideal pitch point to its location under load. The shifts

The predatory behavior of ants: an impressive panoply of morphological adaptations
Insect Science, EarlyView.This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...
