“…Se encontró que una tercera parte de los adolescentes tenía sobrepeso y obesidad. El análisis de varianza mostró la existencia de diferencias estadísticas significativas en la escala de psicoticismo, lo que indica mayor agresividad, hostilidad e insensibilidad en las emociones de los adolescentes con normopeso. …”

“…Furthermore, the conductivity studies provide insights into understanding the transport phenomena in the samples. The oxygen vacancies resulting from the addition of LaCoO(3) into the Na(0.5)Bi(0.5)TiO(3) ceramics are responsible for the relaxation and conduction processes, and the charge carrier is doubly ionized oxygen ion vacancies. …”

“…The photocatalytic activity of the BiLa(1.4)Ca(0.6)O(4.2) powder to degradation of RhB under visible light irradiation is measured and improved more than 7 times by annealing in nitrogen ambient, indicating that annealing in nitrogen can effectively improve the photocatalytic activity by producing oxygen vacancy. …”

“…The electrochemical reduction of molecular oxygen is a fundamental process in Solid Oxide Fuel Cells and requires high efficiency cathode materials. Two La(0.25)Ba(0.25)Sr(0.5)Co(0.8)Fe(0.2)O(3−δ)-based perovskite compounds were prepared by solution combustion synthesis, and characterized for their structural, microstructural, surface, redox and electrochemical properties as potential cathodes in comparison with Ba(0.5)Sr(0.5)Co(0.8)Fe(0.2)O(3−δ) and La(0.5)Sr(0.5)Co(0.8)Fe(0.2)O(3−δ) perovskites. …”
