We prepare a series of mixed brushes of two incompatible polymers, polystyrene (PS) and poly(2-vinylpyridine) (P2VP) grafted by end groups to Si wafers from carboxyl-terminated P2VP (MW(P2VP) 42 kg/mol) and carboxyl-terminated PS. The molecular mass of PS ranged from 2.98 to 75 kg/mol. The mixed brushes are bidisperse (asymmetric) with respect to the difference of molecular mass of P2VP and PS while the polydispersity of PS and P2VP is narrow. We expose the mixed brushes to selective solvents (toluene ...

The AUDIT-like tests system was created for complex assessment and evaluation of the addictive status of adolescents in a Ukrainian population. The AUDIT-like tests system has been created from the Alcohol Use Disorders Identification Test (AUDIT) developed by the World Health Organization. The AUDIT-like tests were minimally modified from the original AUDIT. Attention was brought to similarities between stages of different addictions (TV, computer games, the Internet, etc.) and alcohol addiction. ...
