La biorremediación de suelos contaminados por hidrocarburos es una técnica que consiste en usar organismos vivos para el consumo de los hidrocarburos de petróleo en el suelo. Esta alternativa de bajo costo permite la recuperación de suelos contaminados con hidrocarburos de petróleo, reduciendo las concentraciones a niveles que no son tóxicos para las plantas (5000 mg/kg de suelo). Para confirmar o descartar la disminución de Hidrocarburos Totales de Petróleo de un suelo de la Refinería la Pampilla, ubicado en Carretera Ventanilla Km 25. Distrito, Ventanilla. Provincia, Callao. Se instaló el experimento a nivel de bioensayo, en el Laboratorio de Fertilidad de suelos de la Universidad Nacional Agraria la Molina, aplicándose el modelo estadístico de Diseño Experimental Completamente al Azar (DCA), con tres repeticiones y doce tratamientos sumando un total de 36 macetas experime...

The objective of the work carried out is to continue research on the effect of chloride ions on the variables that determine the behavior of concrete as a protective covering for reinforcing steel, when it is subjected to the environmental conditions of the marine coast of the Peruvian coast. Considering the relevance of the water / cement ratio in obtaining the compact properties of concrete and therefore in the ease with which chlorides can diffuse in this medium, we proceeded to prepare aggregates from the region with groundwater and Type I Portland cement, forty-five 75 x 150 mm cylindrical specimens, which after undergoing 1, 3 and 7 days of curing were paraffin-watered on all sides except in a basal plane and then immersed in water tridistilled with sodium chloride of high purity degree, in proportions similar to the salinity conditions of the Pacific Ocean in the Peruvian coast. A...

In order to establish the horizontal nets four contiguous quadrilateral ones were realized or in chain and ligatures to the national net by means of 4 geodesic points with base of exit in S.E.B. Conchán and whose coordinated geographical ones it measured itself to the system of global position geodesic GPS for 2 hours in every apex. Supported on these apexes one formed the net of the four quadrilateral ones, and for the compensation and adjustment by means of the mathematical hardware classic and verified with computers hardware of the formed figures, one raised the processes of classic or traditional geodesy and the process in block. It is observed that the error becomes bigger and bigger and concentrates on the central apexes of the net being the maximum changes in arranged in the apexes Pachacamac and Guayabo with -0.018m and -0.008m respectively, and indicates that the above mention...

Para establecer las redes horizontales, se realizó cuatro cuadriláteros contiguos o en cadena y ligados a la red nacional por medio de 4 puntos geodésicos con base de partida en S.E.B. Conchán y cuyas coordenadas geográficas se midió con el sistema de posicionamiento global GPS geodésico durante 2 horas en cada vértice. Apoyados en estos vértices, se formó la red de los cuatro cuadriláteros, y para la compensación y ajuste mediante las herramientas matemáticas clásicas y verificadas con las computacionales de las figuras formadas; se planteó los procesos de geodesia clásica o tradicional y el proceso en bloque. Se observa que el error se hace cada vez más grande y se concentra en los vértices centrales de la red siendo las máximas variaciones en las ordenadas en los vértices Pachacamac y Guayabo con -0.018m y -0.008m, respectivamente; e indica que dichos vértices del...

In the projects of geodesic and topographical engineering, precise mathematical calculations are carried out in a fast way and economic to apply it to the designs of the works of engineering, so much in the urban and rural space. Because of it the development of the Geodesic and topographical Information System called program present (SisTopGeo), is going to permit us to execute several of the very useful applications and of common use in Topography, Geodesy and basic Astronomy, permitting iterative immediate results, the ones that will be obtained entering the data of field and with only pressure the button calculation, the dependable results will be obtained, the same that will permit immediately to be represented in a plan A they determined extension of land, through existing programs of drawing as Autocad Land, Civil CAD, among others. With the data and results obtained applied to th...

The present research had like specific objective to develop a methodology that, having a solid theoretical sustenance, allows to determinate the direction o fan alignment with a minimum precision that serves as a base for all civil infrastructures Project in urban and rural spaces. For which after a specialized bibliographical revision and of the ordering of concepts, the analytical processes and the evaluation of the results allowed the exposition in direct form the determination of the geographic azimuth by solar observations, being obtained with this form a precision of the order of ± 30´´.
