Phytochemical investigation of a propolis sample from Alto Santo - Ceara, Brazil, allowed identification of triterpenes (lupeol, lupenone, germanicone, Canaric acid) and flavonoids (quercetin, kaempferol and acacetin), which were identified by spectroscopic data (IR, MS, and NMR, including 2D techniques). This is the first report of Canaric acid in propolis. Propolis extract and flavonoids showed antioxidant activity using a DPPH radical scavenging assay. (author)

The texts of the Convention on Early Notification of a Nuclear Accident (CENNA) and the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency (CANARE) are preceded by brief remarks on their origin. The World Health Organization is bound to carry out the activities envisaged, by virtue or its constitutional responsibility for ''promoting, developing, assisting and coordinating international health work''. The Executive Board thus recommends that the WHO accede to both conventions

escolaridad debido al alto costo de oportunidad que representa no viajar a una nación en donde, el emigrante aún de poseer bajos niveles educativos recibe ingresos superiores a los que en iguales circunstancias recibiría en el país de origen.  Adicionalmente a lo expuesto, es conveniente señalar que el sistema educativo ecuatoriano y su baja inversión han determinado bajos  incentivos a continuar los estudios.Palabras Claves: Familia transnacional, Flujos Migratorios, Remesas, Tasa Deserción escolar, Tasa no promoción escolar, Valor Agregado Bruto no petrolero___________________________ABSTRACT:Ecuador, like many Latin American countries, has high outward migration flows, which have determined changes in the economic performance of regions. In recent years, the country has migratory behavior of changing migratory characteristics, ranging from the gender composition, which is now more equitable, to changes in the regions of origin and destination of migrants. Thus, in the last decade the largest migration flows come from the high-productive provinces of Pichincha and Guayas, and the main destination is Spain. While the main benefit that generates phenomena of this nature is the remittance to the mother countries, its effect has not exceeded the purely economic level. In Ecuador it has achieved better results in the balance of payments, and also an increase in the consumerist levels of people, but it has also meant greater reliance of the regions from this type of income, which has stuck the autochthon productive development of the region. Additionally, the effects of variables of great importance for the socioeconomic development of nations, such as education, have not been more encouraging. The province of Canar is one of the Ecuadorian provinces to have the higher immigration history apart the highest rate of migrants over the total population, and the flow of remittances they generate represents about 70% of non-oil gross value added. But these features have not
