Diagnostic Use of Testing for Novel Murine Autoantibodies for Sjögren Disease in the Rheumatology Outpatient Setting

open access: yesArthritis Care &Research, EarlyView.
Objective The goal was to assess the diagnostic performance of three novel autoantibodies (NA) for Sjögren disease (SjD) by comparing NA prevalence in patients with SjD, other autoimmune rheumatic diseases (ARDs), nonspecific chronic sialadenitis (CS), and controls.

An evaluation of operation and creep life of stationary gas turbine engine [PDF]

open access: yes, 2012
During operation, gas turbine components undergo various types of timedependent degradation due to high temperatures and mechanical loading. In the case of stationary GT engines for mechanical power, creep failure mechanism problems are a very common ...

Assessment of creep and compressive strength: bulk-fill versus conventional composites

open access: yesBMC Oral Health
Backgrounds Creep of composite restorations is affected by their exposure to oral fluids. This study sought to assess the effect of media (water and 75% ethanol) and time storage on creep and compressive strength of bulk-fill and conventional composites.

Temporal Trends and Short‐ and Long‐Term Mortality of People With Acute Myocardial Infarction and Rheumatoid Arthritis: A Nationwide Cohort Study

open access: yesArthritis Care &Research, EarlyView.
Objective We investigated whether a diagnosis of rheumatoid arthritis (RA) affects the quality of inpatient acute myocardial infarction (AMI) care and long‐term mortality post‐AMI. Methods We analyzed data from 784,091 adults, 6,047 with a diagnosis of RA, from England and Wales hospitalized with AMI between 2005 and 2019 from the Myocardial Ischaemia ...

Multiscale modeling of upper mantle plasticity: From single-crystal rheology to multiphase aggregate deformation [PDF]

open access: yes, 2014
We report a first application of an improved second-order (SO) viscoplastic self-consistent model for multiphase aggregates, applied to an olivine + diopside aggregate as analogue for a dry upper mantle peridotite deformed at 10 15 s 1 shear strain rate ...

Associations of Sleep and Shift Work With Osteoarthritis Risk

open access: yesArthritis Care &Research, EarlyView.
Objective Daily rhythms may be critical for maintaining homeostasis of joint tissues. We aimed to investigate the relationships among circadian clock disruption, sleep, and osteoarthritis (OA) risk in humans. Methods In the UK Biobank, a prospective 500,000–person cohort, we evaluated associations among sleep duration, sleeplessness/insomnia, and shift

Trajectories of Physical Function in Canadian Children With Juvenile Idiopathic Arthritis

open access: yesArthritis Care &Research, EarlyView.
Objective We describe trajectories of physical function in children newly diagnosed with juvenile idiopathic arthritis (JIA) and identify trajectories with persisting functional impairments and associated baseline characteristics. Methods We included patients enrolled in the Canadian Alliance of Pediatric Rheumatology Investigators (CAPRI) Registry ...

Creep data sheet for Nickel-based 19Cr-18Fe-3Mo-5Nb-Ti-Al superalloy

open access: yesScience and Technology of Advanced Materials: Methods
Creep data of Ni-based 19Cr-18Fe-3Mo-5Nb-Ti-Al superalloy (JIS NCF718-B) were obtained at 550°C to 750°C under 100MPa to 1000MPa and analyzed to determine the 100,000 h creep rupture strength.

Effect of initial tempers on mechanical properties of creep-aged AA2050

open access: yesManufacturing Review, 2019
The evolution of mechanical properties of a third-generation Al–Cu–Li alloy, AA2050, with different initial tempers (as-quenched WQ, naturally aged T34 and peak-aged T84) during creep-ageing has been investigated in this study.
