      The purpose of this article is to describe the subjective experience of the diagnosis of Attention Defi ci t and Hyperacti vi ty Di sorder (ADHD) and the cul tural meani ngs that shape thi s experience. Based on interviews ...
    • Echeverri, Andrea; Gomez, Tatiana; Hadad, C. Z. (Elsevier B.V., 2019)
      Small metallic clusters -mediated gas phase catalysis studies give lights to understand simple and complex catalytic processes, and help in the discovery and explanation of non-traditional “molecular-scale” catalytic ...
    • Billi, Marco; Blanco, Gustavo; Urquiza, Anahí (Springer Netherlands, 2019)
      Over the last few decades climate change has been gaining importance in international scientific and political debates. However, the social sciences, especially in Latin America, have only lately become interested in the ...
    • San Miguel Espinosa, Camila Paz; Rámila, Consuelo; Leiva, Eduardo; Lizama Allende, Katherine (North Carolina State University, 2019)
      Constructed wetlands (CW) are being explored as an alternative treatment for boron removal. The efficiency of CW strongly depends on the substrate and plants used. A promising and inexpensive substrate is rice husk. This ...
    • Chudinzow, Dimitrij; Haas, Jannik; Díaz Ferrán, Gustavo; Moreno Leiva, Simón; Eltrop, Ludger (Elsevier, 2019)
      Bifacial photovoltaics (bifacial PV) offer higher energy yields as compared to monofacial PV. The development of appropriate models for simulating the energy yield of bifacial PV power plants is a major topic in both ...
    • Muñoz, Lisa; Pineda, Fabiola; Martínez, Carola; Sancy, Mamié; Urzúa Acevedo, Marcela; Flores Carrasco, Marcos; Encinas, María V.; Páez, Maritza A. (Elsevier, 2019)
      To better understand the effect of surface treatments on the efficiency of protective coatings of aluminum alloys, this study assessed different surface treatments for the aluminum alloy AA2024, including mechanical ...
    • Guerrero Gatica, Matías; Aliste, Enrique; Simonetti Zambelli, Javier Andrés (MDPI AG, 2019)
      There are two barriers to accomplishing restoration of ecosystems: insufficient information about historical baselines to guide restoration, and shifts between the actual baselines and perceptions about historical conditions. ...
    • Cassels Niven, Bruce (Natural Product Incorporation, 2019)
      Alkaloids of the Cactaceae have been studied for the last 120 years. The first half of that period provided the "classic" compounds, after which a large number of usually very similar analogs were isolated or determined ...
    • Doornenbal, R. J.; Roldán Molina, A.; Núñez Vásquez, Álvaro; Duine, R. A. (American Physical Society, 2019)
      We show that an inhomogeneity in the spin-transfer torques in a metallic ferromagnet under suitable conditions strongly amplifies incoming spin waves. Moreover, at nonzero temperatures the incoming thermally occupied spin ...
    • Clemens, Michael A.; Montenegro Muñoz, Claudio; Pritchett, Lant (MIT Press Journals, 2019)
      Large international differences in the price of labor can be sustained by differences between workers or by natural and policy barriers to worker mobility. We use migrant selection theory and evidence to place lower bounds ...
