This study examines the mechanical and fracture behavior of glass fiber-reinforced epoxy laminates enhanced with graphene nanoplatelets (GNPs) to explore the effect of GNP through-thickness distributions on tensile, pin-...

Abstract Penetration and non-penetration lap laser welding is the joining method for assembling side facade panels of railway passenger cars, while their fatigue performances and the difference between them are not compl...

In the field of long-life fatigue, predicting fatigue lives and limits for mechanical com- ponents is crucial for ensuring reliability and safety. Fracture mechanics tools have enabled the estimation of fatigue lives for...

An in‐situ microscopic analysis of the damage mechanisms of ferritic ductile iron under uniaxial tensile testing is carried out in this work. The experimental methodology combines specialized metallography techniques, ...

In the present work, the mechanical performance of polylactic acid (PLA) based composites reinforced with hydroxyapatite (HA) or β-tricalcium phosphate (β-TCP) was investigated. The polymer was melt compounded with 1 a...

Duplex stainless steels fabricated by Laser Bed Powder Fusion (LPBF) exhibit refined and metastable microstructures that can be particularly sensitive to intermediate-temperature exposure. In this study, the effect of 47...

Objective and MethodTo achieve rapid coalbed methane (CBM) extraction from broken-soft coal seams using surface horizontal wells, this study proposed a volume fracturing technology for coal seam roof using horizontal wel...

Emergency management of oromaxillofacial trauma with anterior cranial base fracture. Oromaxillofacial trauma with cranial base fracture is a case that is quite commonly found in the ER of Oral and Maxillofacial Surgery ...

La osteoporosis es un trastorno para tener en cuenta en niños con patologías crónicas graves o con algunas enfermedades genéticas que predisponen al incremento de la fragilidad ósea. La osteoporosis primaria es una ...

Bone mineral density (BMD) is the tool for diagnosing osteoporosis in older adults. However, BMD alone is not sufficient for deciding who should be given treatment at either the individual patient or the public health le...

Osteoporosis constitutes a major public health problem through its association with age related fractures. Fracture rates are generally higher in caucasian women than in other populations. Important determinants include ...

"Discrete Fracture and Matrix (DFM) models describe fractured porous media as complex sets of 2D planar polygons embedded in a 3D matrix representing the surrounding porous medium. The numerical simulation of the flow in...

ABSTRACT Introduction Osteoporosis is a bone disorder highly prevalent in post‐menopausal women and is an important predisposing factor towards bone fractures. It is commonly classified based on BMD, which is estimated...

Blunt trauma, particularly from traffic accidents, is a leading cause of multiple facial fractures. Managing such injuries can be extremely challenging for surgeons, especially when multiple facial regions are involved. ...

Abstract Current research on the fabrication of rolled composite plates primarily focuses on processing and bonding mechanisms. Compared with hot-rolling technology, the electrically assisted rolling process has demonstr...

Abstract Background Endoluminal tracheal stenting can relieve signs associated with tracheal collapse syndrome (TCS) in dogs, but major complications can result. Objective To identify associations among tracheal dimensio...

Background: Methamphetamine (meth) is an addictive stimulant that increases risk of trauma and infections. Global meth use continues to rise and the economic impact of meth use on the orthopedic trauma system is poorly u...

ABSTRACT: Dental and maxillofacial injuries represent an important but underrecognised component of trauma during episodes of violent crowd control. Blunt and projectile forces directed toward the head frequently result ...

Abstract Ice shocks associated with the springtime thermal expansion of ice represent a manifestation of fracture processes in a complex nonlinear medium. In this study, we investigate temporal changes in statistical cha...

The effect of partial substitution of Ce by Pr ions in BaCe1−xPrxO3−δ (0 ≤ x ≤ 0.8) perovskite was studied to improve the proton conductor capability, including transport and mechanical properties, thermodynamic...

This study investigates the tensile mechanical properties of gray sandstone under dynamic impact. Drawing on the one-dimensional stress wave theory, we conducted a one-dimensional spallation experiment using a 50 mm diam...

Abstract Cast iron alloys with low production cost and quite good mechanical properties are widely used in the automotive industry. To study the mechanical behavior of a typical ductile cast iron (GJS-450) with nodular g...

OBJETIVO: Avaliar a densidade mineral óssea (DMO) e os fatores de risco associados à osteoporose na pós-menopausa. MÉTODOS: Estudo clínico transversal com 431 mulheres (idade 40 - 75 anos). Foram incluídas mulheres...
