The intervention targeted both communication about safer(More)

Highly luminescent semiconductor quantum dots have been synthesized in porous materials with ultraviolet and x-ray lithography. For this, the pore-filling solvent of silica hydrogels is exchanged with an aqueous solution of a group II metal ion together with a chalcogenide precursor such as 2-mercaptoethanol, thioacetamide or selenourea. The chalcogenide(More)

Determinants of safer sexual behaviors among HIV-infected adult men with hemophilia were examined. A model was proposed that personal adjustment, communication skills, self-efficacy, and perceived advantages of condom use would influence safer sex practices.
