The competences that humans need in a new era
Cayolla, Ricardo; Marques, PaulaThe purpose of this article is to present a conceptual model of the future competences needed for human beings to be successful. Starting from the theory of constructivism, we argue that in an increasingly faster and unpredictable, more automated and digital world, human beings who improve an intrinsically human set of competences will have a better chance of future success. More than skills, these competences ...
Effect of rice grain (Oryza sativa L.) enrichment with selenium on foliar leaf ...
Marques, Ana Coelho; Lidon, Fernando C.; Coelho, Ana Rita F.; Pessoa, Cláudia Campos; Luís, Inês Carmo; Campos, Paula Scotti; Simões, Manuelagrant number 101-030671; An agronomic itinerary for Se biofortification of two rice cultivars (Ariete and Ceres) through foliar fertilization with sodium selenate and sodium selenite with different concentrations (25, 50, 75 and 100 g Se.ha−1), was implemented in experimental fields. The selenium toxicity threshold was not exceeded, as shown by the eco-physiological data obtained through leaf gas exchanges. The...
Quantification and tissue localization of selenium in rice (Oryza sativa l., po...
Marques, Ana Coelho; Lidon, Fernando C.; Coelho, Ana Rita F.; Pessoa, Cláudia Campos; Luís, Inês Carmo; Scotti-Campos, Paula; Simões, Manuelagrant number 101-030671; In worldwide production, rice is the second-most-grown crop. It is considered a staple food for many populations and, if naturally enriched in Se, has a huge potential to reduce nutrient deficiencies in foodstuff for human consumption. This study aimed to develop an agronomic itinerary for Se biofortification of Oryza sativa L. (Poaceae) and assess potential physicochemical deviations. ...
