The research starts from the analysis of data obtained from objective situations, generated by volatile organic compounds in routine molding and casting operations in order to determine the predominant factors that affect environmental quality due to the use of furan resin in the preparation of molds for the manufacture of cast parts that is based on the principle of complying with the objectives proposed in the environmental protection regulation that regulates the development of activities in the manufacturing industry, as well as analyzes such activities during the production process in the manufacture of parts mentioned, assuming and verifying the environmental impacts that are generated in the previously determined area of ​​direct influence, proposing preventive measures that mitigate and correct the possible deviations in the processes that alter the balance of the physical an...

The actual existence of cyanide in very significant environmental catastrophes indicates that the cyanide management in the mining operation must be improved. Specifically, disposing right standard in the design and the construction of tailing disposals, water managing, qualification and training labor, fauna protection and the good operation of the systems of warning and emergency, all are areas of high-priority attention. The main reasons of the environmental incidents in the mining operations comes from poor design of management of process waters, the design and the construction and maintenance of tailing disposals, in addition to the frequent accidents in the cyanided pulp transport. In the present investigation, we try to get a cyanide layout of the gold and silver recovery process in the plant of processes of Orcopampa of Buenaventura Company of mines, In order to get it we have sa...

El presente trabajo de investigación se desarrolló tomando como sustento o base, el análisis de los datos obtenidos a partir de situaciones objetivas generadas por los compuestos orgánicos volátiles en operaciones rutinarias de fundición y moldeo para así poder determinar el grado de contaminación y daño ambiental por resinas furánicas en la preparación de moldes para la fabricación de piezas fundidas de hierro dúctil, que, se sustenta en el principio de cumplir con los objetivos y metas dadas por el reglamento de protección ambiental para el desarrollo de actividades de la industria manufacturera, así como también en el análisis de dichas actividades durante el proceso de producción y fabricación de las piezas mencionadas, para ello, se toma en cuenta los posibles impactos ambientales que estas actividades generarían en una determinada área de influencia. En funció...

Debido al crecimiento de la población de Lima Metropolitana y, por tanto, de la demanda habitacional, las edificaciones de viviendas en la ciudad capital se están expandiendo hacia zonas o áreas fuera de la metrópolis, lo cual afecta al valle Lurín. La ciudad de Lima y su área metropolitana ha pasado de tener 520,000 habitantes en 1940 a 6´700,000 habitantes en 1995, y más de 7´000,000 de habitantes hacia finales de siglo XX. Este crecimiento explosivo se debe a tasas de crecimientos vegetativo elevadas (2.44 % anual), en concordancia con este tipo de fenómenos en casi toda América Latina; pero, en especial, es el resultado de fuertes corrientes de migración interna (Ecoriesgo, 1995). Se generan impactos negativos generales sobre la calidad de vida y el paisaje de la ciudad. En el escenario descrito, la expansión metropolitana hacia el cono sur ha sido la última en el tiemp...

In 1941, Huaraz city was affected by a flood from Palcacocha glacier lagoon, thenceforth the city grew significantly occupying areas exposed to floods. For future risks analysis, city growth prospective evaluation is necessary, being logistic regression a widely used technique. Using geomatic tools, aerial and satellite photographs from 1948, 1962, 1977, 2011 and 2018 were visually and geometrically corrected taking cadastral map 1:10,000 as base cartography. With complementary field work polygons of urban/populated areas were obtained within a 25 km² analysis zone, with which the historical spatial trend and growth characteristics were analyzed in relation to variables such slope, altitude, distance from city middle center, direction growth and point density; which were used as independent variables in the regression logistic model being the dependent the 2018 urban/populated coverage....

The purpose of this article is to compare alternatives for the reuse of organic solid waste generated by catering services, this research will be carried out by verifying studies no older than 5 years to date, denoting their progress in each method. to be used, by comparing the methods and results of each study, in order to define the best reuse alternative, taking into account the cost benefit, the advantages, disadvantages and the feasibility of each study. Therefore, in the present investigation, the result was to opt for the reuse of composting, because it is a process that generates great profits at little cost, in general 80% of organic waste is reused, on the other hand, we have the use through the generation of energy by obtaining biogas, being a slightly more complicated process due to the higher incidence in cost/benefit of this reuse alternative. Therefore, the article conclud...

The East Pisco basin belongs to the group of basins of the Peruvian forearc. This basin has been studied based on the description and interpretation of excellent outcrops along the coast. the East Pisco basin in its offshore area is characterized by a complex tectonic history which has been interpreted in this study with subsurface information (2D-3D seismic) and integrated with the geological information of the coastal sector. This paper shows the interpretation of seismic horizons corresponding to stratigraphic units, the main fault, and folding systems. The main structural styles of the basin are determined, and a model of tectonic evolution is proposed.
