One hundred fifty-six biogenic calcites and 96 whole rock carbonate samples of Paleozoic and Mesozoic age have been analysed for their sulfur isotopic composition. Recorded in structurally substituted sulfate (SSS) in the calcite lattice, the sulfur isotopic composition is thought to reflect the sulfur isotope value of ambient seawater sulfate. Possible alterations of the signal have been asses...

Quality issues concerning very low-sulfur fuel oil (VLSFO) have increased significantly since the IMO sulfur-limit regulation became mandatory in 2020, as most VLSFO is produced by blending high-sulfur (HSFO) with VLSFO. For instance, conversion of paraffins (C19 or higher alkanes) into waxes at low temperatures adversely affects cold flow properties. This study investigates effects ultrasonica...

Following an accidental human exposure to a vesicating agent, plasma samples were analyzed for specific biomarkers of sulfur mustard. One individual suffered chemical burns over 6.5% of the body surface area and required hospitalization; the second individual developed a single, small blister. Plasma specimens from both individuals were examined using two different assays. The first assay targe...

Due to the extraordinarily high theoretical capacity of sulfur (1675 mAh g 1), the lithiumesulfur (LieS) battery has been considered a promising candidate for future high-energy battery applications. LieS batteries, however, have suffered from limited cycle lives, mainly due to the formation of soluble polysulfides, which prevent the practical application of this attractive technology. The enca...

Rice cultivation has been challenged by increasing food demand and water scarcity. We examined the responses of water use, grain yield, and water productivity to various modes of field water managements in Chinese double rice systems. Four treatments were studied in a long-term field experiment (1998-2015): continuous flooding (CF), flooding-midseason drying-flooding (F-D-F), flooding-midseason...

Soybean [Glycine max (L.) Merr.] genetic diversity is limited because domesticated soybean has undergone multiple genetic bottlenecks. Its progenitor, the wild soybean [Glycine soja Siebold & Zucc], has not undergone the same intense selection and is much more genetically diverse than domesticated soybean. However, the agronomic importance of diversity in wild soybean is unclear, and its weedy ...

Polioencephalomalacia (PEM) is a neurologic condition in ruminants that can be caused by several dietary factors including water deprivation-sodium ion toxicosis, lead poisoning and high sulfur intake. Three month old calves on a 1500-cow dairy experienced neurologic problems during three separate episodes. The morbidity rate approached 75% each time. Based upon post-mortem examination, three o...

water deficit stress is the most important environmental constraint for growth, yield and productivity of crops, including the oil seed crops. this study was aimed at studying the influence of differing irrigation régimes on growth, chlorophyll , proline and some antioxidants content along with grain yield, yield components and oil content of sesame genotypes using a 4-replicate split plot rand...
