Effects of the "Unplugged" school-based substance use prevention program in Nigeria: A cluster randomized controlled trial.

Background: School-based programs are the most convenient interventions to tackle substance use among youth. "Unplugged" is a Social Influence universal school curriculum developed and tested in the "EU-Dap" project. In 2015, Nigeria implemented a large-scale project to promote healthy lifestyles in schools, families and communities.

Knowledge, attitudes and behaviours on tobacco, alcohol and other drugs among Nigerian secondary school students: Differences by geopolitical zones.

Introduction And Aims: Nigeria is composed of six geopolitical zones plus one Federal Capital Territory. Differences between zones can differentially influence the adoption of risk behaviours by adolescents. This paper aims to describe the knowledge, attitudes, beliefs, risk perception, skills and substance use among Nigerian secondary school students highlighting the differences by geopolitical zone.

The investigation of phenol removal from aqueous solutions by zeolites as solid adsorbents.

This work reports results on phenol adsorption from aqueous solutions on synthetic BEA (β) and MFI (ZSM-5) zeolites, studied by heat-flow microcalorimetry. For the sake of comparison, the adsorption was performed on activated carbon, a solid customarily used for removal of phenol from water. The obtained values of heats evolved during phenol adsorption indicate the heterogeneity of active sites present on the investigated systems for the adsorption of phenol.

The adsorption of nicotine from aqueous solutions on different zeolite structures.

The present work is focused on the adsorption of nicotine from aqueous solutions. Based on the data available in the literature, serious concern is claimed regarding the appearance of nicotine in ground, surface and municipal wastewaters. In order to investigate the possibility of abatement by adsorption, three different types of zeolites (BEA, MFI and HEU) have been applied as adsorbents.
