Millions of people throughout the world are abusing substances such as alcohol, nicotine, cocaine, methamphetamine, morphine, marijuana, heroin and many others. Methods: This is a cross-sectional survey with the use of questionnaires to estimate the prevalence of substance abuse among the professional college students in Bikaner Rajasthan. The study was conducted during 2018-19 by using self-administered questionnaires that included demographic parameters and questions about substance abuse. Results: The total prevalence of substance abuse among professional college students was found to be 29.5%. Male students had significantly higher prevalence of substance abuse as compared to female counterparts (43.26% versus 7.74% respectively). The most common substance being abused was Alcohol (27.75%) followed by tobacco (9.25%). Conclusion: Prevalence of substance abuse among professional college students is high and causes significant problems in this population; therefore there is necessity of targeted interventions to reduce this huge burden.

This study investigates the influence of filter surface energy (14-43 mN/m), micro-and nanoscale surface roughness on wetting, mobility and coalescence of isooctane droplets (5-10 ll) in immiscible water surrounding and explains their role in emulsion separation performance of nanoparticle coated filters. In water, coalescence among the oil droplets primarily takes place at filter surface. Despite different interfacial energies in air and water surrounding, the influence of substrate roughness on droplet mobility is same in both the surroundings. For effective separation of oil-in-water emulsion with a surface filter, it should be super hydrophilic, oriented vertically and have pore size smaller than the dispersed droplet size. In addition, the influent side of a surface filter should possess sufficient micro-and nanoscale surface roughness to provide high mobility, coalescence of the oil droplets and thereafter their easy detachment. For effective separation of oil from water a coalescing filter should be hydrophobic-oleophilic, oriented vertically with rough fibers surface to offer strong adhesion with the oil droplets and thereby high coalescence efficiency.
