Deposition of electroless Ni–P graded coatings and evaluation of their corrosion resistance

Abstract: Electroless Ni–P coatings provide high hardness and excellent resistance to wear and abrasion The present work aims to study the formation of electroless Ni–P graded coatings, with varying nickel and phosphorus contents of the individual layers and to evaluate their corrosion resistance by polarization and electrochemical impedance spectroscopic studies The possibility of preparing electroless Ni–P graded coatings by sequential immersion in three different plating baths is discussed The study reveals that electroless Ni–P graded coatings offer better corrosion resistance than non-graded Ni–P coatings

When HIV-prevention messages and gender norms clash: the impact of domestic violence on women's HIV risk in slums of Chennai, India.

Abstract: This paper examines how marital violence affects women's ability to protect themselves from HIV/AIDS. In-depth interviews (n = 48) and focus groups (n = 84, 3–7 per group) were conducted among men and women in two randomly selected slums of Chennai, India. The study showed that community gender norms tacitly sanction domestic violence that interferes with adopting HIV-preventive behaviors. Given the choice between the immediate threat of violence and the relatively hypothetical specter of HIV, women often resign themselves to sexual demands and indiscretions that may increase their risk of HIV acquisition. In conclusion, AIDS-prevention interventions must incorporate gender-related social contexts in settings where husbands strictly enforce their locus of control. HIV-prevention messages targeting men may effectively reduce women's exposure to HIV/AIDS.
