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

Assessment of the hydrological and coupled soft computing models, based on different satellite precipitation datasets, to simulate streamflow and sediment load in a mountainous catchment

Journal of Water and Climate Change, 2023
This study evaluated the performance and hydrologic utility of four different satellite precipitation datasets (SPDs), including GPM (IMERG_F), PERSIANN_CDR, CHIRPS, and CMORPH, to predict daily streamflow and SL using the SWAT hydrological model as well

Phosphorus lability across diverse agricultural contexts with legacy sources

Journal of Environmental Quality, EarlyView.
Abstract The buffering of phosphorus (P) in the landscape delays management outcomes for water quality. If stored in labile form (readily exchangeable and bioavailable), P may readily pollute waters. We studied labile P and its intensity for >600 soils and sediments across seven study locations in the United States. Stocks of labile P were large enough

Atrazine Ecological Monitoring Program: Two decades of generating daily or near‐daily monitoring data in highly vulnerable watersheds

Journal of Environmental Quality, EarlyView.
Abstract Surface water monitoring of pesticides ensures adherence to environmental and human health regulatory requirements. This study focuses on an unprecedented monitoring program spanning two decades with daily or near‐daily sampling across 13 states in the US Midwest and Southern United States, targeting watersheds in the upper 20th percentile of ...

Effects of obesity‐associated plasma markers on adipose stem cell function and epigenetic regulation

Obesity, EarlyView.
Abstract Objective This study investigates the correlations between obesity‐related plasma markers and epigenetic/inflammatory changes in white adipose tissue (WAT), focusing on adipose‐derived stem cells (ASCs). We hypothesize that obesity modulates histone H3K27 marks, modified by demethylases (lysine‐specific demethylase 6A and 6B [KDM6A/KDM6B]) and

Sensitivity analysis of the DEM resolution and effective parameters of runoff yield in the SWAT model: a case study

Journal of Water Supply: Research and Technology. Aqua, 2020
This study investigates the impact of different digital elevation model (DEM) resolutions on the topological attributes and simulated runoff, as well as the sensitivity of runoff parameters in the Mahabad Dam watershed in Iran.

Nephroprotective Effects of Fraxinus Hookeri Wenz. Against Renal Toxicity and DNA Oxidative Damages Induced by CCl4 in Rats

ChemistryOpen, EarlyView.
This study evaluates the nephroprotective potential of Fraxinus hookeri Wenz. (F. hookeri), a medicinal plant of the Oleaceae family, against CCl4‐induced oxidative stress. The findings demonstrate its ability to restore antioxidant defenses, renal function markers, and DNA integrity while reducing lipid peroxidation and histopathological damage.

Evaluation and verification of new UK air temperature extremes during the July 2022 heatwave. Part 2: minimum temperatures

Weather, EarlyView.
The brief but intense heatwave that affected all areas of the British Isles during the third week of July 2022 was particularly noteworthy as being the first occasion on which screen temperatures exceeded 40°C anywhere in the United Kingdom. The event resulted in widespread new records for high air temperatures, both day maximum and night minimum. This

Contents of deposits from the archaeological site of Sobolów in Bochnia—A contribution to prehistoric foundry activity

Archaeometry, EarlyView.
Abstract In the Sobolów area, three hoards of the Hallstatt period were discovered, containing ornaments, waste and scrap of tin–lead–bronze alloy, with iron objects in close proximity, possibly indicating the existence of a foundry workshop. They were accompanied by glass beads, an indicator of the settlement of the Lusatian EB‐Ha Culture, found ...
