The European Commission, DG XII, has published the 1993 Annual Report of the Human Capital and Mobility (HCM) programme. The report contains information on all contracts entered into under the HCM programme in 1993. The Report is divided into seven scientific disciplines: - Mathematics and information sciences; - Physics; - Chemistry; - Life sciences; - Earth sciences; - Engineering sciences; - Economics; - Social and human sciences. Each chapter contains contractual data, names and addresses, and the title of research for all fellowships, networks and Euroconferences. The projects covered by large-scale facilities, which are inter-disciplinary in nature, are in a separate chapter. In addition, for each network and large-scale facility project, a full abstract of the research, with indexed keywords and a complete list of partners, is given. HCM supports basic and applied research projects throughout the exact, natural and human sciences. HCM comprises four main activities: - Fellowships for research, organized either by individuals or by institutes; - Support for research networks, which bring together research teams from different countries; - Grants to facilitate access for researchers to Europe's large-scale research facilities; - Assistance to organizers of Euroconferences. The 1993 HCM Annual Report is published in two volumes.
