Laser surface treatment was carried out to enhance the performance of Ni‐Al2O3 coatings on HSS substrates. The results revealed improved microstructural features, corrosion resistance and significant reduction in slurry erosion wear with 18 W laser treatment. ABSTRACT The sliding wear between hydraulic vane tip and the inner surface of the cam ring can

The Future of Native Bees in Australia Under Environmental and Anthropogenic Change
Bees are considered one of the most important and abundant pollinators across the globe, yet they are under threat from anthropogenic activities such as land‐clearing, urbanisation, agricultural activities, pesticide use, non‐native flora and fauna introductions, disruption of natural fire regimes, pollution and climate change, among others.

Diffusion MRI of the Body: Beyond PGSE‐EPI
ABSTRACT Diffusion magnetic resonance imaging (dMRI) is a widely used clinical imaging technique which is sensitive to changes in tissue microstructure including cellularity, perfusion, and tissue damage. DMRI has been used in whole‐body imaging as well as in targeted imaging of every major anatomical region.

Research on Particle Motion Characteristics in a Spiral-Vane-Type Multiphase Pump Based on CFD-DEM
In oil–gas mixed transportation using spiral-vane-type multiphase pumps, high sand content often causes wear on flow-passing components. To reveal the motion patterns of particles, a three-stage spiral-vane-type multiphase pump was selected as the ...

Wind turbines influence several abiotic conditions in the environments they are sited in and may influence the behavior and movement of insect pollinators. It is unknown how operating turbines influence plant–pollinator interactions. To investigate if pollination dynamics could be affected by the presence of wind turbines, we recorded videos of ...

Abstract The lungs have for a long time been recognised as having pharmacological significance as a specific organ to modulate the pharmacokinetics of endogenous substances needed to maintain homeostasis. The lungs are therefore the site of action of certain drugs that act on these homeostatic processes, resulting in systemic effects on the ...

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years
Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

ABSTRACT Rationale Quantum cascade laser absorption spectroscopy (QCLAS) is a fast and reliable method for analyzing the bulk (𝛿13C‐CH4, 𝛿D‐CH4) and clumped isotopic (∆13CH3D and ∆12CH2D2) composition of methane. However, precise measurements of ∆12CH2D2 require 0.5 to 1.8 mmol of purified methane (equivalent to 15 to 40 mL at STP).
