Effects of fracture aperture and roughness on hydraulic and mechanical properties of rocks : implication of seismic characterization of fractured reservoirs [PDF]

, 2005
Roughness and aperture are two important characteristic parameters controlling fluid flow in natural joints and fractures. It has been demonstrated by many authors that knowledge of roughness does not directly lead to that of aperture, and aperture ...

Age-related changes to macrophages are detrimental to fracture healing in mice. [PDF]

, 2020
The elderly population suffers from higher rates of complications during fracture healing that result in increased morbidity and mortality. Inflammatory dysregulation is associated with increased age and is a contributing factor to the myriad of age ...

Analysis of localized oxides and oxide films formed on alloy 625 and 617 in supercritical water and superheated steam environments at 750°C

Mechanical Engineering Journal, 2017
Oxidation tests using coupon specimens of alloy 625 and alloy 617, and four-point bending tests for a duration of 100 hrs were carried out in supercritical water (SCW) environment at a pressure of 24 MPa and in superheated steam (SHS) environments at 750°

Hangman’s fracture vs hanged-man’s fracture vs hangee’s fracture [PDF]

Acta Neurochirurgica, 2013
not necessarily a male. The conventional name of “hangman’s fracture”, therefore, should be “hanged-person’s fracture”. Accordingly, we suggest that a more suitable terminology for the so-called “hangman’s fracture” may be the “hangee’s fracture”.

Preparation and performance evaluation of electrothermal actuators using aligned carbon nanotube reinforced epoxy composites

Mechanical Engineering Journal, 2016
By using an aligned multi-walled carbon nanotube (MWCNT) reinforced epoxy composite, an electrothermal bimorph actuator was fabricated and its load and deformation capacities were investigated.

Fracture through cavitation in a metallic glass [PDF]

, 2008
The fracture surfaces of a Zr-based bulk metallic glass exhibit exotic multi-affine isotropic scaling properties. The study of the mismatch between the two facing fracture surfaces as a function of their distance shows that fracture occurs mostly through

Mechanical and thermal expansion properties of aligned carbon nanotube reinforced epoxy composites

Mechanical Engineering Journal, 2019
Aligned MWCNT/epoxy composites made with the three types of the multi-walled carbon nanotubes (MWCNTs) with different thermal annealing temperature have been prepared, and the tensile tests and thermal expansion tests of the composites in the MWCNT ...

The effect of aquatic exercise on bone mineral density in older adults. A systematic review and meta-analysis

Frontiers in Physiology, 2023
Introduction: Aquatic or water-based exercise is a very popular type of exercise in particular for people with physical limitations, joint problems and fear of falling.

A genome-wide association study demonstrates significant genetic variation for fracture risk in Thoroughbred racehorses [PDF]

, 2014
Background: Thoroughbred racehorses are subject to non-traumatic distal limb bone fractures that occur during racing and exercise. Susceptibility to fracture may be due to underlying disturbances in bone metabolism which have a genetic cause.

Analysis of the Bauschinger Effect in Cold Drawn Pearlitic Steels

Metals, 2020
Prestressing steel wires usually undergo cyclic loading in service. Therefore, it is of interest to analyse certain features of their mechanical behaviour under this type of loading, such as the Bauschinger effect (BE) or the hardening rule, that fit the
