NOUVELLES [ET ANCIENNES] DONNÉES SUR L'ART MÉGALITHIQUE EN ALENTEJO

L'art mégalithique identifié dans le sud du Portugal est présent dans deux types de monuments: les menhirs (simples ou regroupés en enceintes mégalithiques) et les dolmens. Ces différents aux niveaux des monu-ments se reflètent aussi sur les motifs représentés, qui sont beaucoup plus abondants et variés dans les menhirs. Dans ces monuments mégalithiques funéraires, l’art était, par manque de preuves, apparemment rare, voire nul, dans cette région. Ce scénario semble maintenant commencer à changer. En fait, grâce à l'un des projets en cours, nous avons identifié les premiers monuments funéraires avec des gravures. Aucuns des motifs identifiés sont typiques des menhirs de l` Alentejo, mais étaient pratiquement inconnus dans les dolmens.

The Branches of Large Electricity Companies in Portugal: From Trade to the Transfer and Adaptation of Technology (20th Century)

In the last decade of the 19th and first decades of the 20th century there was a movement of capital and engineers from the central and northern Europe to the countries of southern Europe and other continents. Large companies sought to obtain concessions and establish branches in Portugal, favouring the circulation of technical knowledge and transfer of technology for Portuguese industry. Among the various examples of the representatives of foreign companies in Portugal we find Jayme da Costa Ltd. established in 1916 in Lisbon, which was a branch of the Swedish company ASEA, as well as STAAL, ATLAS DIESEL (Sweden), Landis & GYR (Switzerland), Electro Helios, etc.. Another example is EFACEC a company founded in 1948 in Porto, that was a partnership between the Portuguese company CUF – Companhia União Fabril, and ACEC – Ateliers de Constructions Électriques de Charleroi and a small entreprise Electro-Moderna Ldª. This enterprise started the industrial production of electric motors and transformers, and later on acquired a substantial share of the national production of electrical equipment. Using Estatística das Instalações Elétricas em Portugal (Statistics on Electrical Installations in Portugal) from 1928 until 1950 we can identify the foreign enterprises acting in the Portuguese market: Siemens, B.B.C, ASEA, Oerlikon, etc. We can also establish a relationship between the development of the electric network and the growth of production and consumption of electricity in the principal urban centres. Finally we see how foreign firms were a stimulus to the creation of national enterprises, especially those of small scale, in Portugal.
