An upper central incisor of 11-mm height was constructed on top of each abutment. Each set was positioned in a virtual bone model and exported to analyze mathematically. A 0.60-mm mesh was created ...

The purpose of this study was to examine and compare the peak von Mises stress distributions in the crown, implant and abutment by using finite element analysis (FEA). Besides, a comparison of the ...

Aim: To investigate the effect of implant-abutment angulation and crown material on stress distribution of central incisors. Finite element method was used to simulate the clinical situation of a ...

The hard roof of coal mines has the characteristics of high hardness, good integrity, and large layer thickness, which leads to many ground control problems. To reveal the influence of a hard roof ...

More specifically, they wondered if nature simulations might reduce the stress of people working in medical facilities during the pandemic. To that end, they recruited 102 front-line workers from ...

A previous version of this story incorrectly reported the percentage of health-care workers in the survey who said their mental health was negatively impacted by worry or stress related to covid-19.

Lauriane Suyin Chalmin-Pui works for the Royal Horticultural Society. She received funding from the Royal Horticultural Society, United Utilities, and ForHousing. However, most of these studies ...

The coal in front of the mining face presents strain softening deformation characteristics. ... For borehole stress gauge 3, the peak abutment pressure is 23.84 MPa, occurring at about 6.2 m from the ...
