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...
Energy and environmental impacts of wheat production: a comparative study of diesel and photovoltaic irrigation systemsNARA Subscribed
Increasing energy demand and environmental concerns have led to interest in renewable energy for agricultural irrigation to promote sustainable agriculture. Therefore, this research aims to assess and compare the environmental impacts and energy of wheat production in Egypt under diesel-driven (Sc-I) and solar PV-driven (Sc-II) irrigation systems. The data was collected from 181 wheat farms during the 2022–2023 season. The env...
Optimization of Beet Thick Juice Storage: Impact of Storage Conditions on the Rheological BehaviorNARA Subscribed
Establishing a manufacturing period for concentrated beet juice is a promising strategy to increase the productivity of white sugar and address climatic variability. Key parameters including temperature and stabilization treatments are crucial to optimizing the storage process at a reasonable cost. To this end, a pilot-scale plant was built with 12 tanks, three levels of storage temperatures (15, 25, and 35 °C), and three disi...
