The solution of Laplace's equation within a Classical Electrodynamics course is fundamental for the understanding of boundary problems in Electrostatics. In the present research work the analytical and numerical solution is obtained by the relaxation method, of a problem of infinite parallel plates, of the Laplace equation in Cartesian coordinates in an Euclidean space of two dimensions, specifically using the Python programming language, for its use in the teaching of Physics and its better phenomenological understanding. Likewise, the solutions obtained by both solution techniques are compared and discussed.

Most of the problems concerning the fluids flow in conduits and tubes they imply the prediction of the conditions in a section of a system, when the conditions of some other section are known. In any section of this system, generally we are worried about the pressure of the fluid, the speed of the flow and the elevation of the section. In a line of pipe in series the loss of total energy is the sum of the great and small individual losses. This affirmation is in agreement with the principle of which the equation of the energy is a way to both take into account all the energy in the system between points. The nature parallel systems requires that the technique used for their analysis is different from which is used in series in the analysis of the systems. In general, a parallel system can have any number of branches. It stops most of the problems of this type, the objective is to determi...

An assessment of part of a family planning program is presented in a social environment characterized by high fertility, low contraceptive use and knowledge and great interest in information and practice of family planning methods. Accidental pregnancy rates and subsequent expulsions are similar to those found in urban environments and sea level. By contrast, first expulsions rates are higher than those established for suburban and metropolitan populations sea level, so it could be considered an effect of biological, possibly related to altitude conditions. The application of IUDs appears to face a number of problems arising from the socio-cultural status of the population. Although theoretically would be the most useful means of contraception in Cerro de Pasco, its use is affected by the limited knowledge of patients on the characteristics of the method, which makes it sensitive to the ...

Debido a los constantes deslizamientos que se producen en lugares cercanos a la zona de estudio, especialmente en épocas de invierno, nos llevó a realizar un estudio más detallado y minucioso acerca de la estabilidad de taludes en roca entre los kilómetros 95 al 97 de la carretera Ciudad de Dios - Cajamarca. Es por ello que la presente tesis se encargará de informar al gobierno central y a la población aledaña si realmente se puede producir un deslizamiento en el tramo mencionado. Para poder llegar a un veredicto final se dividió en siete estaciones geomecánicas a la zona, en donde se calculó la cohesión y ángulo de fricción interno de la roca mediante el criterio de rotura de Barton - Bandis, se analizó la cinemática de los taludes, a ello se sumó el cálculo de la densidad de las unidades litológicas aflorantes y finalmente los datos obtenidos se ingresaron a los softw...

Lake Titicaca, at present, is considered a natural wonder of the world. It is the habitat of many unique and endangered native species, with flora and fauna of great diversity, site of nesting of many migratory birds, source of fresh filtered water, by its volume, regulates the air temperature of the region allowing climate conditions less aggressive for life. However, in the last decades, the anthropogenic influence affected its conservation. The problems that Lake Titicaca presents are concentrated in the littoral zone, the bays and the Lake Minor. Large quantities of wastewater that enter directly or poorly treated, in particular to the Bays of Puno and Copacabana, are generating eutrophication processes. The effect of the discharges are the increase of sediments accumulated in the bottom, explosive flowering of Lemna sp. algae on the surface, reduction in dissolved oxygen levels, and...

The research is based on the problems encountered in the production process of companies in the metalworking sector. The problem arises from the low availability of machines in the production process due to working conditions (39.5%), poor maintenance management (40.3%) and poor-quality control (20.2%) that generate low profitability for business. As a solution, Lean Manufacturing tools are implemented to improve the process and increase profitability. The improvement proposal consists of a series of stages: first, the definition of indicators for the measurement of the variables; then, the design and implementation of a pilot in the production process and, in parallel, a simulation system will be designed to evaluate the long-term results. The document concludes that the implementation of the proposed tools will increase the availability of machines and an OEE to 55%, avoiding defective...

La ciudad de Lima presenta cada día mayor contaminación, siendo esta la causa del incremento de las enfermedades respiratorias. La OMS advierte sobre el daño en el desarrollo neurológico, psíquico y motor que genera la contaminación del aire, asimismo el 93% de la población mundial de niños está expuesta a niveles de partículas finas PM2.5 por encima de lo permitido. El 40% de la población mundial está expuesta a elevados niveles de contaminación de aire en su hogar debido a la quema de leña, carbón y otros desechos sólidos. La contaminación del aire y del entorno de los pobladores de Lima Cercado está generando el aumento de enfermedades cerebrovasculares, canceres de pulmón, neuropatías crónicas y agudas, como el asma. La contaminación del aire no solo de da por la contaminación de partículas sino también por la presencia de Dióxido y Monóxido de Carbono, Nit...

En el presente trabajo se expone el planificación y principio del proyecto “Mega Mercado Municipal de Sullana”, ubicado Sullana, Piura. Este proyecto parte con el estudio y análisis de la problemática de la zona, la cual se basa principalmente, en la necesidad de los comerciantes de tener un lugar de calidad para poder ofrecer sus productos a los consumidores. Para el desarrollo del proyecto se realizo varias visitas de campo para analizar los posibles usuarios y/o beneficiarios para saber sus necesidades y funciones a realizar en el proyecto, ademas de zonas y sub zonas a desarrollar en el proyecto; posteriormente procesaremos la información obtenida mediante cuadros y estadisticas y datos reales sobre los números de puestos comerciales formales y el número de comerciantes informales de cada zona y subzona a la que pertenecen cada uno, tratando de cumplir con la demanda requer...

El presente trabajo de investigación tiene como objetivo proponer estrategias de movilidad sostenible que vayan acorde a las características geográficas, demográficas y económicas actuales y armonice con un futuro ordenamiento territorial. El interés de este esfuerzo es proponer soluciones a las dificultades que afronta un distrito rural andino peruano, como la falta de interconectividad, pobreza, inadecuadas condiciones de vida y pocas oportunidades para desarrollarse social y económicamente. El documento consta de ocho capítulos, comenzando con una introducción que relata una reseña histórica del distrito, el marco normativo a revisar, la problemática estudiada desde diferentes enfoques y las metodologías referenciales de casos de estudios similares. En el marco teórico, se definirán conceptos importantes de la movilidad, sostenibilidad, ordenamiento territorial y tráns...
