A review of the development and implementation of the critical source area concept: A reflection of Andrew Sharpley's role in improving water quality

Journal of Environmental Quality, EarlyView.
Abstract Critical source areas (CSAs) are small areas of a field, farm, or catchment that account for most contaminant loss by having both a high contaminant availability and transport potential. Most work on CSAs has focused on phosphorus (P), largely through the work in the 1990s initiated by Dr.

Sodium Retention in Large Herbivores: Physiological Insights and Zoogeochemical Consequences

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
Sodium travels twice as fast through the bodies of large herbivores in urine than feces. The specific pathway of element assimilation, retention and release exerts an important constraint on the contributions of wildlife and domestic livestock to nutrient recycling and redistribution.

Magnetic Resonance Acoustic Radiation Force Imaging (MR‐ARFI)

Journal of Magnetic Resonance Imaging, EarlyView.
This review covers the theoretical background, pulse sequence considerations, practical implementations, and multitudes of applications of magnetic resonance acoustic radiation force imaging (MR‐ARFI) described to date. MR‐ARFI is an approach to encode tissue displacement caused by the acoustic radiation force of a focused ultrasound field into the ...
