Notes
The chemical science community of Armenia has carried heavy loss with the passing of Prof. Aida Avetisyan on October 19, 2009. Professor Avetisyan was an extraordinary person, and all her life was devoted to the service of chemical science and its teaching in the walls of the Yerevan State University. She forever has connected scientific activity with the chemistry of heterocyclic compounds containing oxygen, nitrogen, and sulfur atoms. Professor Avetisyan has brought a significant contribution to education and professional training of many students and young specialists. Professor Avetisyan's students, colleagues, and friends will remember for a long time her image—an image of the multitalented scientist and teacher.
