Strawberry ( Fragaria × ananassa Duch.) is a high-value global crop, yet its productivity is severely constrained by the two-spotted spider mite, Tetranychus urticae Koch. Developing localized economic thresholds is a cornerstone of sustainable Integrated Pest Management (IPM) to mitigate yield losses and reduce acaricide reliance. This two-season field study (2019–2020) investigated the quantitative relationship between T. ur...
Effect of milling on natural radioactivity of Egyptian zircon sand: an assessment of alpha and beta radiation emissionsNARA Subscribed
This study aims to investigate the effect of milling on the natural radioactivity of Egyptian zircon sand, focusing on the gross alpha (α) and goss beta (β) activity concentrations, with additional evaluation of calcination and sulfuric acid leaching. Zircon samples were milled for different durations, and their gross α and gross β activity concentrations were measured using an ATOMTEX AT1329 sample counter. The measurements s...
