El crecimiento expansivo metropolitano en el sur global: un proceso transformacional sui géneris. by Sousa-González, Dr. Eduardo

“…En este sentido, la evidencia empírica ha demostrado que una de las particularidades que puntualiza a esta evolución transformacional ciudad-metrópoli, es aquella que tiende a mostrar fases secuenciales en el proceso de urbanización, las cuales no sólo están asociadas con la concentración creciente de pobladores que tienden a aglutinarse en espacios físicos definidos; sino también, la manera particular en que se concentran los empleos que involucran a los sectores secundario y terciario a partir de un centro metropolitano; constituyéndose así, en agrupaciones de concentraciones demográficas dominantes con múltiples limitantes de política pública, que puedan incidir positivamente en un control eficiente, efectivo y eficaz (EEE) de su hinterland espacial de orientación periférica.…”

Preparation and Characterization of Cu and Ni on Alumina Supports and Their Use in the Synthesis of Low-Temperature Metal-Phthalocyanine Using a Parallel-Plate Reactor by Sánchez de la Torre, Fernando, De la Rosa, Javier, Kharisov, Boris I., Lucio Ortiz, Carlos J.

“…Ni- and Cu/alumina powders were prepared and characterized by X-ray diffraction (XRD), scanning electronic microscope (SEM), and N2 physisorption isotherms were also determined. The Ni/Al2O3 sample reveled agglomerated (1 μm) of nanoparticles of Ni (30–80 nm) however, NiO particles were also identified, probably for the low temperature during the H2 reduction treatment (350 °C), the Cu/Al2O3 sample presented agglomerates (1–1.5 μm) of nanoparticles (70–150 nm), but only of pure copper. …”
