A model is sought from the variables of the production process to forecast the surface hardness of 3-inch diameter steel balls. The DI indicator in replacement of chemical composition is considered as an independent variable. The analyzed data corresponds to 43 controls. In which 10 independent variables and a dependent variable are initially considered as the surface hardness of the ball (HRC). The data treatment begins with a descriptive analysis of the type of relationship between the independent and dependent variables, and then reduces the independent variables, then applies the multiple linear regression method. The initial model to be considered is of the type Y = β0 + ΣβiXi + ε to later be Y = β1X1 + β2X2 + β3X3 + β4X4 + β5X5 + β6X6 + β7X7 This model was evaluated, multicollinearity, between independent variables by the inverse matrix method of correlations. Normality ...

Enseñar a niños con el Trastorno del Espectro de Autismo (TEA) es una práctica inclusiva de gran relevancia debido al incremento considerable de este mal en el Perú, siendo de suma importancia afrontar el problema desde la práctica pedagógica. Por ello, se ha planteado como objetivo general determinar el nivel de conocimiento que tienen los docentes sobre las estrategias de enseñanza de niños con el Trastorno del Espectro del Autismo en escuelas privadas de Puente Piedra. En cuanto a la metodología se ha utilizado el enfoque cuantitativo de tipo descriptivo simple y de diseño no experimental. La muestra estuvo conformada por 44 docentes de educación primaria de diversas escuelas privadas de dicho distrito (Lima-Perú). El instrumento empleado fue un cuestionario de tipo escala Likert y la técnica fue la encuesta virtual que pasó por un proceso de validación por el juicio de...

En Perú, las familias de estudiantes con Trastorno del Espectro Autista (TEA) enfrentan desafíos significativos al buscar colegios que brinden educación regular inclusiva adecuada. En ese contexto, la presente tesis se enfocó en analizar los desafíos y oportunidades en la implementación de políticas de educación inclusiva en dos colegios de la región Piura, uno público y otro privado. Esta investigación se basó en el marco teórico de los "burócratas de la calle" y variables normativas y no normativas de la teoría "bottom-up" de análisis de políticas públicas, a través de las cuales se analizó el proceso de adaptación curricular y la discrecionalidad de los docentes encargados, así como la organización interna y la interacción de la DRE y la UGEL entre sí y con las instituciones educativas. La metodología incluyó entrevistas con representantes del equipo Servici...

Nowadays, the management of foundry machinery is expensive and complicated, not only because of the energy used, but also because of the polluting, lengthy and dangerous process. This perspective is relevant given that, in many metallurgical micro-enterprises, and even educational center laboratories, waste is generated that is sold at a very low price and a product made from virgin material is purchased, increasing the expense, time and natural consumption in the foundry process. The following innovation work develops a prototype proposal for a foundry process that provides optimization for the metallurgical industry on a smaller scale. The approach includes placing the material (waste) in a heating system that works through a conduction transfer, which is theoretically supported due to the short-circuit process complemented by Joule's Law, which is the conversion of electrical energy i...

In this paper we formulate and apply the Exergy Analysis the set heat energy consumption elements of a typical plant of fishmeal, estimating experimentally the specific heat of the solid- liquid-vapor mixtures that form the raw material and steam, in order to optimize energy consumption by changes in the original installation and thus achieving the reduction in operating costs. Usually in these plants conventional energy balance and the premise that the specific heats are physical single phase flows is used; however, when solid-fat-water-steam mixture flows are presented, as is the case, these simple energy balances in each heating element become weak and lead to a high error margin in energy system assessment. In the methodology, the specific heats of mixture flows fat-water-vapor-solid is estimated by measurement of indicators in the industrial plant, contrasted with laboratory standar...

El presente estudio tuvo como objetivo conocer las experiencias de madres primerizas con hijos/as con TEA que se encuentren en la etapa preescolar en Lima Metropolitana. Se realizó una investigación cualitativa con enfoque fenomenológico, y se empleó el análisis temático para encontrar patrones de experiencias en las madres entrevistadas. Se entrevistó a 7 madres de niños/as con TEA de entre 3 y 5 años de edad. Los resultados fueron divididos en seis ejes temáticos: Primeras señales y duelo al confirmar TEA en sus hijos/as, preocupaciones por la vida futura del hijo/a, desafíos y ajustes en la maternidad de un niño/a con TEA, interacciones madre-hijo/a, satisfacciones, logros y aprendizajes, y redes de apoyo y contención en la maternidad. Se encontró que las experiencias de maternidad involucran procesos que atraviesan desde el dolor, pasando por la aceptación y persevera...

In  this case study, an experimental module of a water-based underfloor heating system, was developed for the thermo-fluids laboratory located in the Universidad Católica de Santa María, with the aim of confirming the possibility of correct emulation of the thermal principles of these type of heating systems within a short time of two hours maximum (due to the high thermal inertia of these systems and the limited time to carry out experimental procedures in laboratories of universities), all this using alternative materials that make easier the process of building and maintenance on a limited budget, while keeping the capability to carry through other experimental procedures related to underfloor heating systems. So that, a proper evaluation of the proposal to use a module to perform experimental procedures related to underfloor heating, can be made. To answer the question posed i...

The main objective of this work to estab1ish the controlled use of heat as a function of the pH in order to destroy all the microorganisms that are this bacterias anaerobic forced thermopiles and essentially mesófilas. The bacteria more resistant esporulada to 1he heat is Clostridium botulinum and it is considered lndicative microorganísm of the sterellization. Another parameter of very important control is the quality of the matter it prevails that it can resist the operations of thermal prcsecution, the classification is made in function to the hat size, weight, color and it forms.

This article shows the process of molding plastic extrusion and injection information that will provide a comprehensive and simple idea in this type of industrial activity.Extrusion is a process used to manufacture products such as PVC pipes , rods and the insulated wire coating plastics and other products of constant section. This process involves heating the plastic and cause its output by pressure through a hole in a certain way and then cooling it in a machine called an extruder.The injection is performed by the injection molding machines in a similar way to the extruders ; except that the extruder while continuously preiona plastic material through unamatriz , makes a fuel entering a cold mold . Then wait until the cold molded material is to be removed from the mold before it is refilled . is used to manufacture products such as taznes , mugs , toys, etc.

In this paper, the technical, financial and legal feasibility of employing solar cogeneration for the food industry sector in Peru will be demonstrated. In consequence, we will quantify the electric and thermal energy obtained from a conventional Rankine cycle, with the particularity that the water used to condense the steam that exits the turbine will be employed for the required processes in the industrial plants, because of the high temperature obtained from the heat exchange with the steam. In addition, we will detail the processes in which the obtained energy will be employed, the quantity of devices to be used in this system, as well as the required specifications and the thermodynamic parameters, for a proper operation of the cogeneration system. Moreover, we will prove the legal feasibility of choosing a solar cogeneration system in the Peruvian legal system, and, in ...
