Depressive symptoms and cigarette smoking among middle adolescents: prospective associations and intrapersonal and interpersonal influences.
Using data from a 4-wave longitudinal study with a school-based sample of 1,218 middle adolescents, the authors investigated the directionality (e.g., unidirectionality and bidirectionality) of the prospective relationship between depressive symptoms and cigarette use within the context of potential confounding variables and common and unique intrapersonal and interpersonal predictors. Findings...
متن کاملThe Relationship between Cation-Induced Substrate Configuration and Enzymatic Activity of Phosphatidate Phosphohydrolase from Human Liver
The mechanism by which bi-and trivalent cations affect human liver phosphatidatephosphohydrolase (PAP) activity was investigated. Bivalent cations up to 1 mM increased PAP activity whereas at higher concentrations the activity of the enzyme decreased. The stimulatory concentration for trivalent cations such as Al3+ and Cr3+, however, was much lower being 2 m M and 1 m M, respectively. All catio...
متن کاملPhase transition of the dry friction between crystalline surfaces induced by normal load
A major source of energy dissipation and surface wear is the kinetic friction at the interfaces of sliding bodies. Traditionally, on a macroscopic scale, this undesirable effect is reduced with lubricating the surfaces by introducing oil into their interface. An interesting phenomenon, called superlubricity, has been reported on a nanometer scale where dry (without lubricant oil) fruition and w...
