Ethylene polymerization was carried out using highly active metallocene catalysts (Cp2ZrCl2 and Cp2TiCl2) in combination with methylalumoxane. Titanium(IV) oxide containing 1% Mn as dopant was used as nanofillers. The influence of filler concentration, reaction temperature and pressure on the catalytic activity and polymer properties was investigated. There was a fourfold increase in the activity of zirconocene catalyst by addition of doped-titania. The morphology indicates that the doped-titania nanoparticles have a nucleus effect on the polymerization and caused a homogeneous PE shell around them. The optimum condition for polymerization was found to be 30 8C.

Objectives: Fishermen are among the most vulnerable groups for human immunodeficiency virus (HIV)/AIDS with reported high prevalence. Poor knowledge base has been evidenced by a few studies. The present study was conducted to assess the knowledge regarding HIV/AIDS among fishermen of the Kutch coast, Gujarat, India. Methods: A descriptive cross-sectional study was conducted among 950 fishermen of the Kutch coast, in the months of January-February 2015. Knowledge of HIV/AIDS of fishermen was assessed using structured interview schedules with 12 questions. The information on socio-demographic characteristics was also obtained. Chi-square test and multivariate logistic regression analysis were used for statistical analysis. The confidence level and level of significance were fixed at 95% and 5%, respectively. Results: A major proportion of participants (57.2%) had no access to any potential source of information and had never heard about HIV/AIDS (65.1%). Some of them were aware of modes of transmission of AIDS but only a few of them knew about the methods of prevention. Only 23.1% of participants were observed with appropriate knowledge regarding HIV/AIDS. Bivariate and multivariate analysis revealed significant variation in the proportion of participants with appropriate knowledge with age and educational status.
