El presente trabajo de investigación, se centra especialmente en la zona oeste de la ciudad de Chiclayo, delimitando la zona oeste por las calles (Av. Salaverry, Panamericana Norte, Av. Augusto B. Leguía, Av. Luís Gonzales y Av. Elías Aguirre.), el objetivo principal en esta zona de estudio es estimar el riesgo sísmico, para cumplir con dicho objetivo, se tuvo que hacer análisis de dos factores agrupados para llegar a lo que es riesgo sísmico, los cuales son el peligro y la vulnerabilidad sísmica. Lo que corresponde a Peligro Sísmico, se decidió utilizar el enfoque probabilístico para lo que es obtención de datos respecto a zona. Se realizaron ensayos de vibración ambiental, teniendo como base la medición de microtrepidaciones, para corroborar las características de suelo con las que se están trabajando. Lo concerniente a vulnerabilidad Sísmica, se evaluó haciendo uso d...

The soot generated in foundry sands is an impediment to the reuse of the sands due to its contamination, therefore catalytic oxidation is necessary to increase the rate of soot oxidation at lower temperatures, improving the energy and environmental efficiency of the recovery process. NiO-CeO2 mixed oxides catalysts were prepared by solvent evaporation method with Ni:Ce molar ratios of 0.5:9.5, 1:9, 5:5, and 9:1, represented as Ni0.5Ce9.5, Ni1Ce9, Ni5Ce5 y Ni9Ce1, respectively and the precursors as CeO2 and NiO catalyst were also prepared through the same method. All the samples were characterized by different techniques based on their chemical, structural, morphological, textural composition, and redox properties. Characterization techniques were N2 sorption (BET method), X-ray diffraction (XRD), thermogravimetric analysis (TGA), H2 temperature programmed reduction (TPR-H2), Raman laser ...

A series of Ce alpha Mn1-alpha O2 catalysts supported on gamma-alumina with various molar concentrations of Ce (alpha, from 0 to 0.90) was synthesized by coprecipitation, applying two different precipitating agents, namely, sodium hydroxide (method 1) and sodium carbonate (method 2), with the use of sodium permanganate as a redox agent for precipitation. XRD profiles of the supported samples revealed the predominant abundance of a typical fluorite crystalline structure. TPR thermograms of supported samples were displaced towards lower temperatures with increasing Mn concentration, in contrast with the bulk samples. The supported Ce-Mn samples exhibited a greater performance in n-hexane elimination than did the corresponding simple oxides. The sample Ce0.33M O-0.67(2) obtained by method 2 presented the best activity, probably due to the enrichment of Ce4+, Mn3+ and Mn4+ surface species, a...
