Assessing photochemical ozone formation in the Pearl River Delta with a photochemical trajectory model [PDF]
, 2010 A photochemical trajectory model (PTM), coupled with the Master Chemical Mechanism (MCM) describing the degradation of 139 volatile organic compounds (VOCs) in the troposphere, was developed and used for the first time to simulate the formation of ...

Synthesis of novel 2-methyl-3-triazolyl chromanone oxime etherderivatives as potential antifungal agents [PDF]
Journal of Mazandaran University of Medical Sciences, 2006 Background and purpose: Despite growing list of antifungal agents, their clinical value has been limited by their relatively high risk of toxicity, the emergence of drug resistance, and insufficiencies in their antifungal activity. This situation has led
