Frailty Predicts Incident Osteoporotic Fractures in Veterans with Rheumatoid Arthritis

Arthritis Care &Research, EarlyView.
Objective Rheumatoid arthritis (RA) is associated with an increased risk of frailty and osteoporosis, but the relationship between frailty and incident osteoporotic fractures in RA is underexplored. Methods Data were from the Veterans Affairs (VA) Rheumatoid Arthritis Registry. Frailty was measured using the VA Frailty Index (VAFI).

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Performance of water quality simulation model for lifting drainage water joints and mixing zone determination

Applied Water Science
Limited water resources with gradual increase in water demand led to higher dependence on drainage water as one of the non-conventional water resources in Egypt. However, there was no precise approach for using such resource. The practices ranged between

Activating the role of women in water projects

Water Science, 2014
Water is one of our most precious natural resources. A growing human population, and the expansion of economic activities that comes with it, will intensify the pressure on water resources.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Early Danian paleotemperature records from Neuquén Basin-Argentina: Applications of the ostracod Sr/Ca paleothermometer

Evolving Earth
The early Danian is marked by a recovery in marine and terrestrial ecosystems after the Cretaceous-Paleogene mass extinction. Both sea surface temperature (SST) and bottom water temperature (BWT) reconstructions are essential for a better understanding ...

Sources of black carbon to the Himalayan–Tibetan Plateau glaciers

Nature Communications, 2016
Black carbon accelerates melting of glaciers in the Himalayas and Tibet, yet the source of these aerosols remains enigmatic. Here, the authors use isotope fingerprinting techniques to determine the origin of black carbon preserved in glacier ice cores ...

Experimental Characterization of Mycelium‐Based Composites Under Multiple Loading Conditions

Advanced Engineering Materials, EarlyView.
This study examines the mechanical response of mycelium‐based composites under compression, shear, and tension using mechanical testing and imaging methods. The comparison between unpressed and hot‐pressed specimens shows that hot pressing is associated with higher compression and shear stiffnesses.

From cylinder to city: how recondensation-induced nucleation in vehicle exhaust shapes urban aerosol number [PDF]

Atmospheric Chemistry and Physics
Air-quality models frequently underestimate fine particle number concentration (PNC), particularly in the nucleation/Aitken range – while reproducing PM2.5 mass more accurately, suggesting that key number-forming processes are missing from current ...

Demographic Change and Climate Change [PDF]

SSRN Electronic Journal, 2019
AbstractThis paper uses a continuous-time overlapping-generations model with endogenous growth and pollution accumulation over time to study the link between longevity and global warming. It is seen that increasing longevity accelerates climate change in a business-as-usual scenario without climate policy.
