A short history of the phosphorus index and Andrew Sharpley's contributions from inception through development and implementation

Journal of Environmental Quality, EarlyView.
Abstract In the 1980s, growing recognition of agricultural phosphorus (P) sources to surface water eutrophication led to scrutiny of animal feeding operations. In 1990, the USDA‐Natural Resources Conservation Service (NRCS) invited prominent scientists to find a solution. It was at an initial meeting that Dr. Andrew Sharpley suggested that P assessment

Optimising Beam Geometry in Orthopaedic X‐Rays: A Phantom Study

Journal of Medical Radiation Sciences, EarlyView.
Antoni Cieszynski, a 19th‐century Polish dentist, developed the bisecting angle technique in 1907, which uses isometry rules to improve anatomical imaging accuracy in dentistry. Our experiment tested this technique on the radius bone at various angles, demonstrating that it significantly reduced elongation and distortion compared to traditional methods,

A Middle and Late Devensian sequence from the northern part of Kents Cavern (Devon, UK)

Journal of Quaternary Science, EarlyView.
Abstract 1920s/30s excavation of a Middle Devensian sequence in the northern part of Kents Cavern recovered important Late Middle and Early Upper Palaeolithic archaeological material, including Britain's oldest known Homo sapiens remains. Questions remain about this material, including how it came to be in the cave.

Dolomite and Mg Calcite as Mineral Thermometers in Mortar Binders. A High Resolution Raman Spectroscopic Study

Journal of Raman Spectroscopy, EarlyView.
Raman band characteristics of calcium carbonates from experimentally heated and recarbonated dolomite samples and of carbonate aggregates in a high‐fired gypsum mortar were correlated using high spectral and spatial resolution micro‐Raman. The band parameters of the carbonate minerals correlate to the applied burning temperature, hence allowing a ...
