Estimation of the GCV of Coal Using Real‐Time Plant Data
Energy Science &Engineering, EarlyView.ABSTRACT Online or real‐time strategies of estimating the gross calorific value (GCV) of coal are still not fully explored in academic literature, even though both conventional and sophisticated offline methods for estimating the GCV are well described.

Geological Journal, EarlyView.Charnockites with 2691–2607 Ma magmatic ages from the NMZ show arc‐magmatic geochemical signatures. They correspond to the lower‐crustal equivalent of the Chilimanzi Suite Granite in the Zimbabwe Craton. Lu‐Hf isotopic data of magmatic zircons show negative εHf(t) values (−11.18 to −2.20) with TDMC ages of 3699–3158 Ma, suggesting their protolith ...

Geological Journal, EarlyView.A. Modeled T‐t paths for samples in the northern Ibex Hills, showing steady cooling throughout much of the Cenozoic, until rapid Miocene cooling. B. Weighted mean paths for each sample in this study. Note that all show a rapid cooling event at or just after 10 Ma, which is interpreted to represent exhumation as a result of regional extenstion ...

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.

Borax Promotes Fertility of Brassica napus Better Than Other Boron Species at Suboptimal Supply
Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background Continuous and sufficient boron (B) supply is essential for achieving maximum yield in Brassica napus. Increasing incidences of environmental water limitation are linked to reduced plant B availability and increased B deficiencies.

Genotypic Variation in Rice Tolerance to Fe Toxicity During Germination and Establishment
Journal of Plant Nutrition and Soil Science, EarlyView.Genotypic difference in Fe tolerance during establishment and the attributable traits. ABSTRACT Background Poor crop establishment caused by Fe toxicity hinders the adoption of direct‐seeded rice cultivation in Fe‐rich soil. To date, there have been few reports on the genotypic variation in rice's Fe tolerance during the pre‐establishment period (i.e.,
