Development of Highly Sensitive Strain Sensor Using Area-Arrayed Graphene Nanoribbons

open access: yesNanomaterials, 2021
In this study, a basic design of area-arrayed graphene nanoribbon (GNR) strain sensors was proposed to realize the next generation of strain sensors. To fabricate the area-arrayed GNRs, a top-down approach was employed, in which GNRs were cut out from a ...

Reduced mortality and subsequent fracture risk associated with oral bisphosphonate recommendation in a fracture liaison service setting: A prospective cohort study [PDF]

open access: yes, 2018
Objective: Osteoporotic fragility fractures, that are common in men and women, signal increased risk of future fractures and of premature mortality. Less than one-third of postmenopausal women and fewer men are prescribed active treatments to reduce ...

Validation of orthopaedic surgeons’ assessment of cognitive function in patients with acute hip fracture

open access: yesBMC Musculoskeletal Disorders, 2019
Background About one fourth of patients with hip fracture have cognitive impairment. These patients are at higher risk of surgical and medical complications and are often excluded from participating in clinical research.

Influence of Loading Rate on the Hydrogen-Assisted Micro-Damage in Bluntly Notched Samples of Pearlitic Steel

open access: yesMetals, 2016
The influence of loading rate (crosshead speed) on the fracture process of bluntly notched samples of pearlitic steel under hydrogen environment is analyzed in this paper.

Implants for trochanteric fractures in Norway: the role of the trochanteric stabilizing plate—a study on 20,902 fractures from the Norwegian hip fracture register 2011–2017

open access: yesJournal of Orthopaedic Surgery and Research, 2021
Background The trochanteric stabilizing plate (TSP) is used as an adjunct to the sliding hip screw (SHS) in unstable trochanteric and subtrochanteric fractures.

Risk factors for hip fracture in white women. Study of Osteoporotic Fractures Research Group.

open access: yesNew England Journal of Medicine, 1995
BACKGROUND Many risk factors for hip fractures have been suggested but have not been evaluated in a comprehensive prospective study. METHODS We assessed potential risk factors, including bone mass, in 9516 white women 65 years of age or older who had ...

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

open access: yes, 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 ...

Impact and indenting damage of CVD-produced ZnS and ZnSe ceramics

open access: yesMaterials Research Express, 2020
Time series of acoustic emission pulses were excited in ductile ZnS and ZnSe ceramics either by a falling weight or by indenting the Vickers pyramid. Energy distributions in emitted acoustical emission pulses were found to be random (Poisson-like) in the
