72-984: The National Atomic Energy Commission ( Spanish : Comisión Nacional de Energía Atómica , CNEA ) is the Argentine government agency in charge of nuclear energy research and development. The agency was created on May 31, 1950, with the mission of developing and controlling nuclear energy for peaceful purposes in the country. CNEA's facilities include the Bariloche Atomic Centre (in San Carlos de Bariloche ), Constituyentes Atomic Centre (in Buenos Aires ), and Ezeiza Atomic Centre (in Ezeiza , Buenos Aires Province ). CNEA operates research reactors at each of these sites. Officially established by President Juan Perón 's Decree No 10.936, CNEA filled

Atucha II
216-658: A Spanish-based creole language called Chavacano developed in the southern Philippines. However, it is not mutually intelligible with Spanish. The number of Chavacano-speakers was estimated at 1.2 million in 1996. The local languages of the Philippines also retain significant Spanish influence, with many words derived from Mexican Spanish , owing to the administration of the islands by Spain through New Spain until 1821, until direct governance from Madrid afterwards to 1898.
