    Sammanfattning : Abstract The constant need to improve health and to prevent disease in Bolivia, especially in the Andean region with its extreme environmental conditions (high altitude and lower temperatures), motivated us to extend studies of antioxidant sources in foods and plants, since antioxidants are believed to have major health benefits. Spectrophotometric methods, such as ABTS (2, 2’- azinobis-3-ethylbenzotiazoline-6-sulfonic acid) and FRAP (ferric reduction antioxidant power), were used to evaluate antioxidant activity. LÄS MER

    Sammanfattning : Archaeology in Bolivia has two strong tendencies: nationalism and regionalism. The proposal aims for an academic reconstruction and expansion of this science in order to develop new scientific criteria, that can be institutionalized and become normative to the whole country to cover the expectations of different regions with regard to its past.
