Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Method of calculation and test of dynamic tooth root strain for high-contact-ratio spur gears

open access: yesJixie chuandong
ObjectiveAiming at the difference of load sharing and dynamic characteristics between high-contact-ratio spur gears and conventional spur gears, a method for calculating the dynamic tooth root strain was proposed considering the dynamic characteristics ...

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

open access: yesThe Anatomical Record, EarlyView.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

Calculation of Tooth Root Bending Fatigue Life with Considering the Influence of Roughness Parameter Ra

open access: yesJixie chuandong, 2018
The stress concentration effect of surface topography plays an important role in the fatigue properties of gears. The quantitative analysis method of the effect of surface topography on gear fatigue performance is the basic work of an in-depth study of ...

The relationship between form and function of the carnivore mandible

open access: yesThe Anatomical Record, EarlyView.
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

基于应力释放提高齿轮弯曲强度方法的研究

open access: yesJixie chuandong, 2014
Stress concentration of the gear tooth root fillet is an important factor to affect the bending fatigue strength of the gear.In order to improve the bending fatigue strength,the stress relief hole in the tooth surface is established to make root stress ...
