Activated carbon and their nanocomposites derived from vegetable and fruit residues for water treatment.

Water pollution remains a pressing environmental issue, with diverse pollutants such as heavy metals, pharmaceuticals, dyes, and aromatic hydrocarbon compounds posing a significant threat to clean water access. Historically, biomass-derived activated carbons (ACs) have served as effective adsorbents for water treatment, owing to their inherent porosity and expansive surface area. Nanocomposites have emerged as a means to enhance the absorption properties of ACs, surpassing conventional AC performance.

Pit and Fissure Sealant versus Fluoride Varnish for the Prevention of Dental Caries in School Children: A Systematic Review and Meta-Analysis.

Children's dental health has become the main concern, due to the increase in caries prevalence amongst children. Pit and fissure sealant (PFS) and fluoride varnish (FV) are effective measures for preventing dental caries. However, the clinical efficacy of these interventions when compared to one another is uncertain.

Vulnerability mapping: A conceptual framework towards a context-based approach to women's empowerment.

•Women's empowerment interventions are not as effective as hoped or intended.•Could be an issue with intervention design and implementation.•Research reveals that there are several limitations to existing women's empowerment approaches.

Problematic internet use: a cross-sectional study on a model from university students in Egypt.

Background: Problematic Internet use in the form of excessive Internet use, excessive social network sites (SNSs) use, and compulsive Internet use (CIU) has been increasing among young adults. However, the association between excessive Internet and SNSs use and CIU have not yet been confirmed. This study aimed to investigate this association and detect the risk factors of excessive Internet use, excessive SNSs use, and CIU among university students in Egypt.

Morphometric Analysis in the Diagnosis of Low-Grade Ductal and Lobular Carcinoma in Situ of the Breast.

Objective: To identify quantitative histological features that can differentiate between low grade ductal carcinoma in situ (LG-DCIS) and classic type lobular carcinoma in situ (C-LCIS).

Study Design: Regions of solid intraductal proliferation from scanned hematoxylin and eosin images of LG-DCIS (20 cases) and C-LCIS (25 cases) were analyzed using Mercator Version 1.0 (ExploraNova, La Rochelle, France).
