Detection of calcium phosphates in calcium oxalate patinas
European Journal of Mineralogy, 2012 Calcium oxalate patinas have been studied on historical monuments for years. In some cases they are associated with calcium phosphate, the presence of which has received contrasted attention and may have been overlooked with the characterisation techniques used.

Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background Soil organic matter (SOM) accumulation in forest soils is strongly influenced by interactions with inorganic constituents derived from parent material mineralogy. However, their role in the forest floor remains underexplored.

Uric acid and calcium oxalate nephrolithiasis
Kidney International, 1983 A 33-year-old man was examined because he formed recurrent renal calculi. At age 22, he had been hospitalized and had undergone ureterolithotomy for a right-sided calculus composed of calcium oxalate monohydrate and uric acid. During the ensuing Ii years, he passed 12 new stones, for which he was hospitalized eight more times, underwent five ...

Journal of Plant Nutrition and Soil Science, EarlyView.Abstract Wet‐chemical extraction of soil to quantify pedogenic species or to remove specific compounds prior to other analyses is an established approach in analytical soil mineralogy and soil chemistry. Interpretation and informational value of data derived from long‐established and frequently used extractions, for instance involving dithionite ...

Boron availability and fertilizer response of maize in soils from sub‐Saharan Africa
Journal of Plant Nutrition and Soil Science, EarlyView.Abstract Background and aims Low boron (B) availability is associated with strongly weathered, coarse‐textured, and low organic matter soils, widespread in sub‐Saharan Africa (SSA). It is unknown to what extent B fertilization can increase maize yields in SSA.

Phosphorus Plant Availability of Biochars Derived From Contrasting Sewage Sludges to Ryegrass
Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background Although phosphorus (P) is an essential element for human life, it is currently sourced unsustainably primarily from non‐renewable phosphate rock sources. Sewage sludge pyrolysis is a method that concentrates nutrients in sludge, a large renewable P source, to produce a sustainable phosphorus fertilizer.

Journal of Raman Spectroscopy, EarlyView.No spectral dataset is perfect, but how severely will imperfection cost you? This study finds that CNNs are more robust against spectral errors than SVMs, particularly with data that exhibits day‐to‐day calibration‐type errors. However, when no artefacts are present, the SVM produces the best model.

Limnology and Oceanography, EarlyView.Abstract Continued human activity is expected to accelerate ocean deoxygenation, leading to the expansion and shallowing of oxygen‐deficient zones (ODZs). This decline in oxygen may impact both phytoplankton growth and trace metal uptake. We conducted culture experiments with Prochlorococcus MIT9313 and Synechococcus XM‐24, two numerically dominant ...

Red Mud as an Additive in the Extrusion of Protein‐Based Porous Materials
Macromolecular Materials and Engineering, EarlyView.Protein‐based foams from agricultural by‐products were altered using red mud, a waste from alumina production, as an additive. Red mud significantly increased elasticity, acting as a plasticizer and redox agent. Strain at break reached 190% in high‐gluten content foams with raw red mud, demonstrating red mud's potential as a sustainable additive for ...
