Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

open access: yesGeological Journal, EarlyView.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

Associations between Nugent‐bacterial vaginosis and preterm birth and other adverse pregnancy outcomes in rural northwestern Bangladesh

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Bacterial vaginosis, defined by Nugent score (Nugent‐BV), has been associated with preterm birth and other adverse pregnancy outcomes. However, few studies have longitudinally described the associations between Nugent‐BV and adverse pregnancy outcomes at varying times in pregnancy.

Assessing the Sustainability of Community‐Managed Irrigation Systems Using Multicriteria Analysis and Sustainability Indicators in Northern Ethiopia: A Holistic Approach

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Reservoir‐based irrigation schemes (RBISs) have been developed to minimize the adverse effects of moisture stress and improve the livelihoods of smallholder farmers in semi‐arid regions. However, many RBISs perform below expectations. A multistage expert elicitation approach and an indicator‐based Sustainability Assessment of Food and ...

Infantile exocrine pancreatic insufficiency due to a homozygous SPINK1 pathogenic variant in two siblings: A case report

open access: yesJPGN Reports, EarlyView.
Abstract Infantile exocrine pancreatic insufficiency is a rare condition, most often encountered in the context of cystic fibrosis or Shwachman–Diamond syndrome. The SPINK1 gene encodes a trypsin inhibitor protein that prevents the premature activation of digestive enzymes in pancreatic tissue.

Raman Signature of the Wings of the Globe Skimmer Dragonfly: Pantala flavescens

open access: yesJournal of Raman Spectroscopy, EarlyView.
Raman spectroscopy is used to confirm the presence of aliphatic and aromatic hydrocarbons and related derivatives including aldehydes, halides, alcohols, acids, esters, and phenols on the wings of Pantala flavescens. The analysis indicates that wing‐surface lipid composition is largely consistent across the three main ecological zones in Ghana. Notably,
