Fallaque-Najar, Joel; Morales-Gomero, Juan-Carlos; Timón, Vicente
The adsorption of ethanol on Au(100), Au(110) and Au(111) surfaces was studied using electronic structure calculations under the scheme of the density functional theory (DFT) with van der Waals corrections, vdW-DF2 and PBE functionals, using numerical atomic orbitals (NAO) basis set implemented in the SIESTA code and plane-waves basis set in the CASTEP code. The lowest physisorption energies using the plane-wave basis set in neutral media were observed at the TOP position in all the surfaces, with values in between -53.35¿kJ.mol-1 and -61.80¿kJ.mol-1. Structurally, the method based on linear combination of atomic orbitals (LCAO) using NAO as basis set gives the best result respect to the ideal bulk. However, the relaxation of the slab is better defined by the plane-wave scheme. Band structure has shown no change in the sp-like bands and the 5d occupied bands with and without the ethanol molecule adsorbed. However, a slight variation was obtained in the unoccupied bands due to the interaction with the lone pair of electrons from the oxygen (non-bonding orbitals).

The purpose of this paper is to improve disaster management models, have an optimal distribution of assets, reduce human suffering in a crisis and find a good solution for warehouse locations, distribution points, inventory levels and costs, considering the uncertainty of a wide range of variables, to serve as a support model for decision making in real situations. Design/methodology/approach: A model is developed based on the recent models. It includes structured and non-structured data (historical knowledge) from a humanitarian perspective. This model considers the uncertainty in a landslide and flood area and it is applied in a representative Peruvian city. Findings: The proposed model can be used to determine humanitarian aid supply and its distribution with uncertainty, regarding the affected population and its resilience. This model presents a different point of view from the efficiency of the logistics perspective, to identify the level of trust between all the stakeholders (public, private and academic). The finding provides a new insight in disaster management to cover the gap between applied research and human behavior in crisis.; El propósito de este documento es mejorar los modelos de gestión de desastres, tener una distribución óptima de activos, reducir el sufrimiento humano en una crisis y encontrar una buena solución para ubicaciones de almacenes, puntos de distribución, niveles de inventario y costos, teniendo en cuenta la incertidumbre de una amplia gama de variables, para servir como modelo de soporte para la toma de decisiones en situaciones reales. Diseño / metodología / enfoque: Se desarrolla un modelo basado en los modelos recientes. Incluye datos estructurados y no estructurados (conocimiento histórico) desde una perspectiva humanitaria. Este modelo considera la incertidumbre en un área de deslizamientos e inundaciones y se aplica en una ciudad representativa del Perú. Resultados: El modelo propuesto se puede utilizar para determinar la oferta de ayuda humanitaria y su distribución con incertidumbre, con respecto a la población afectada y su capacidad de recuperación. Este modelo presenta un punto de vista diferente de la eficiencia de la perspectiva logística para identificar el nivel de confianza entre todos los interesados (público, privado y académico). El hallazgo proporciona una nueva perspectiva en la gestión de desastres para cubrir la brecha entre la investigación aplicada y el comportamiento humano en crisis.

This Statement represents the voice of participants in the 22nd IUHPE World Conference on Health Promotion, held in Curitiba, Brazil, in May 2016. The Brazilian political context at that time greatly influenced the drafting of the Curitiba Statement, which was considered by many participants as an opportunity to categorically express that Brazilian democracy was threatened, as well as the danger of fiscal austerity implemented by many governments of the world. The conference organizers also perceived the launching of this Statement as an opportunity to influence the WHO Shanghai Declaration, since it very strongly stated the influence of commercial interests and corporate practices of the market that are harmful to health. The Curitiba Statement gathers 120 suggestions made by conference participants and focuses on how strengthening health promotion and equity can improve people’s lives. The 21 recommendations were summarized and resulted in appeals to International Organizations, all levels of Governments, Health Sector, Citizens, Health Professionals and Researchers. Unlike a declaration from government summit that are restricted by governments negotiations from different ideological spectrum, the Curitiba Statement was developed in a free environment to foster professional activism. We reaffirm that the objectives of Health Promotion in the Sustainable Development will only be fully achieved by incorporating these four fundamental principles: democracy, social justice, social mobilization and equity. Health Promotion in the twenty-first century needs new narratives and inputs from professional associations, which can be more assertive and to influencing the official declarations of government

Con el apoyo del Instituto de Investigación Científica (IDIC) de la Universidad de Lima, se realizó una investigación técnica mediante ensayos con diversos combustibles utilizando un banco de pruebas para motores a gasolina y diésel. Ya que en el Perú en los últimos años se ha empezado a utilizar mezcla de combustibles con alcohol y biodiesel, se ensayó diferentes porcentajes de mezcla, tanto para motores a gasolina, como diésel, obteniéndose resultados favorables para el medio ambiente. El trabajo concluyó con la publicación del libro titulado “Manual de Combustibles Alternativos y Tecnología Automotriz”.
