Banana Postharvest Quality: Current Technologies And Future Perspectives, Mohamed Ibrahim Elsayed

Journal of King Abdulaziz University: Meteorology, Environment and Arid Land Agriculture

Banana (Musa spp.) is a main economic crop. Several pre and postharvest factors are controlling fruit quality. Oweing to its climacteric nature numerous biological and metabolic changes occur rapidly within fruits and accelerate their ripening and senescence. These changes cause considerable postharvest losses that reduce supply chain efficiency. There is always a pressing and persistent necessity to minimize these losses and develop the current postharvest technologies. Nanoparticle technology has shown promising potential in fruit postharvest including banana. Further research is needed to provide more comprehensive knowledge of these promising materials.

Determinants Of Food Management Behavior On Food Waste Reduction And Household Food Security Through Expenditure Efficiency And Energy Consumption, Prita Dhyani Swamilaksita, Yayuk Farida Baliwati, Drajat Martianto, Dodik Briawan

Media Kesehatan Masyarakat Indonesia

Food Waste (FW) in urban households remains a serious issue as it contributes to economic losses, reduced dietary quality, and weakened food security. This study aims to identify the dominant factors influencing food management behavior, FW generation, and their implications for household food security in urban settings. A cross-sectional design was applied with urban households as the study population, and samples were selected using purposive sampling. Data were analyzed using Structural Equation Modeling (SEM) within the framework of the Theory of Planned Behavior (TPB) and Nudge Theory. The results indicate that attitude (β = 0.42; p < 0.01), subjective norm (β = 0.31; p < 0.05), and perceived behavioral control (β = 0.36; p < 0.01) significantly influence intention toward food management. Furthermore, intention strongly predicts actual food management behavior (β = 0.55; p < 0.001), which subsequently reduces FW (β = –0.47; p < 0.001). Reduced FW positively affects both food expenditure efficiency (β = 0.39; p < 0.01) and energy intake adequacy (β = 0.34; p < 0.05), two critical indicators of urban household food security. Behavioral factors play a crucial role in reducing FW and strengthening food security in urban households. Therefore, behavior-based interventions using TPB and Nudge Theory are recommended to be integrated into food education programs, household assistance, and urban food security policies to ensure effectiveness and sustainability.

Integration Of Mechanism-Driven Computational Modeling And Public Data Resources For Chemical Toxicity Assessment, Elena Chung

Theses and Dissertations

Regulatory toxicology depends primarily on animal testing, which limits throughput, mechanistic interpretability, and applicability to human-relevant endpoints. This dissertation presents computational approaches that integrate publicly available bioactivity data with machine learning to support chemical safety evaluation. Oral carcinogenicity was modeled using curated chemicals from the US Environmental Protection Agency’s Integrated Risk Information System (IRIS) and activity data from over 1,900 PubChem assays. Quantitative structure-activity relationship (QSAR) models trained on statistically prioritized assays demonstrated strong predictive performance and were applied to rank the carcinogenic potential of more than 16,000 compounds. Hepatotoxicity was evaluated using a hybrid modeling approach that combined structural …

Journal of King Abdulaziz University: Medical Sciences

Background: Anemia can adversely affect cognitive development in infants and children, potentially leading to challenges in cognition, motor control, social interaction, and neurophysiological functioning. Full-term infants do not develop iron deficiency anemia within the first four months of life, as they are born with sufficient iron stores accumulated during their intrauterine life. These stores are usually adequate for four to six months of postnatal life. However, exclusive breastfeeding beyond six months without iron supplementation can increase the risk of iron deficiency anemia, as breast milk does not provide enough iron to meet the growing infant’s demand. The American Academy of …
