The aim of this study was to determine the influence of the design of the sagittal split ramus osteotomy (SSRO) on the mechanical resistance to vertical forces. An in vitro study was designed for 30 test specimens. Two osteotomy models were made on two polyurethane hemimandibles, where group I presented a SSRO with an angle at vestibular level between both molars and group II presented a linear...

Mechanical strain plays a critical role in the formation, proliferation and maturation of bone cells. However, little is known about the direct effects of different magnitudes of mechanical strain on osteoclast differentiation. The aim of the present study was to investigate how the fusion and activation of osteoclasts can be regulated by mechanical strain magnitude using the RAW264.7 mouse mon...

The increasing penetration of load model in distribution systems may significantly affect voltage stability of the systems, particularly during Low Voltage Ride-Through (LVRT) wind turbine. The main objective of this work is to present the impact of different static and dynamic load models, on the LVRT recovery after disturbances. A component and composite loading structures are considered, com...

High mechanical performances of macroscopic graphene oxide (GO) papers are attracting great interest owing to their merits of lightweight and multiple functionalities. However, the loading role of individual nanosheets and its effect on the mechanical properties of the macroscopic GO papers are not yet well understood. Herein, we effectively tailored the interlayer adhesions of the GO papers by...

Natural materials have shown their ability to adapt their geometry in response to mechanical stress. In examining their shape and structure, it becomes apparent that the major strategic function of structural materials and systems involves mechanical support under changing load. This comparison study examines how the morphology of four biological materials (bone, wood, plant stems, and blood ve...

BACKGROUND AND PURPOSE Inspiratory muscle weakness and fatigue has been documented following prolonged mechanical ventilation despite successful weaning from mechanical ventilation. This report describes the application of inspiratory muscle training in two patients following successful discharge from an intensive care unit (ICU) after prolonged mechanical ventilation. METHODS Both patients u...

Dense Silicon nitride was investigated to determine the effect of its microstructural parameters and densification on thermo-mechanical properties and thermal stress resistance to fracture initiation during a hot or cold mechanical and thermal shock testing. The different materials and microstructures were obtained by changing the parameters such as the type of the powder, additive, forming p...
