Almost 1 million people have left the Republic of Moldova since 1991, according to other sources, about - 800,000. About 44% of the population aged between 18 and 40 years (both skilled and unskilled) have indicated serious plans to emigrate. This phenomenon affected as well the scientific community of the Republic of Moldova.

This is why Diaspora option can successfully mobilize the intellectual capacity that the scientific Diaspora owns, and can contribute to the development of the country of origin in various fields. These are the main subjects that are studied in the present scientific article.
