Characterisation of Drought and Wet Events in the Paraíba do Sul River Basin—Brazil
International Journal of Climatology, EarlyView.Trend analysis identified statistically significant reductions in precipitation (at the 5% significance level) at specific pluviometric stations in São Paulo and Rio de Janeiro, while other areas, mainly in Minas Gerais, experienced significant increases in annual and seasonal rainfall, particularly during summer and spring. These significant trends at

International Journal of Climatology, EarlyView.We downscale CanESM2 with the Regional Climate Model version 4 (20 km) and evaluate against 15 stations to derive monthly PET (Hargreaves–Samani) and SPEI for northeastern Iran (1990–2009, 2040–2059, 2080–2099). Results show robust PET increases and a shift toward more negative monthly SPEI—especially April–September—indicating earlier onset and longer

Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Accurate quantification of soybean storage protein subunits glycinin (11S) and β‐conglycinin (7S), and their ratio (11S/7S), is essential for applications in plant breeding, food processing, and allergen research. Although sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS‐PAGE) is widely used due to its accessibility ...

The FEBS Journal, EarlyView.Homologous recombination (HR) in Schizosaccharomyces pombe is essential when mating‐type switching–induced double‐strand breaks (DSBs) form at the mat1 locus. In h90 and h− strains, efficient mat1 DSB formation renders HR indispensable unless suppressors block these breaks.
