he mathematical modeling of the physical phenomenon of conduction in the presence of heat sources has various uses in engineering ranging from heat diffusion, pollution generation in large cities and chemical reactions. From the mathematical theory, the study of physical phenomena with the presence of heat is approached from techniques of polynomial approximation, analysis of variations and numerical methods. In this research a mathematical model is proposed to study the heat conduction in a metal bar with a heat source. In the first part of the work, by the application of the method of ...

The scope of a variety of experiments involving the transfer of heat in engineering applications is evident in research on thermal studies throughout the department of Norte de Santander, Colombia. From the energy optimization processes in the brickworks of the province of Ocaña to the didactic use in the Universidad Francisco Santander, Ocaña, Colombia. In this sense, mathematical models will be a fundamental tool in the understanding of thermal transfer processes. The aim of this work is to establish a mathematical model by numerical methods to determine the physical process of heat ...

Las tecnologías digitales han generado cambios en la forma de comunicarnos social, profesional, administrativa y académicamente. Como consecuencia de ello, las formas de enseñar y aprender son distintas a la de años anteriores, con lo que se significa que el contexto pedagógico y el rol docente han cambiado. Los jóvenes de hoy están rodeados de pantallas y de tecnologías, lo que ha provocado que las formas de aprender y de actuar sean disimiles a la época pasada; en consecuencia, se hace EL ROL DOCENTE Y ESTUDIANTE EN LA ERA DIGITAL REVISTA BOLETÍN REDIPE 10 (2): 287-294 - ...

Los acuerdos comerciales (AT) son instrumentos elaborados e implementados por los formuladores de políticas con el objetivo de mejorar el comercio entre países o regiones/bloques económicos. En este estudio, se utilizó un modelo gravitacional para estimar los efectos dentro de un panel de 165 países, examinando las exportaciones chilenas en los sectores total, agrícola y manu-facturero. Los hallazgos se alinean en gran medida con las expectativas teóricas: la presencia de TLC tiende a impulsar las exportaciones de Chile a los países socios, observándose un efecto más pro-nunciado para ...

Physical phenomena are typically described in different areas of knowledge using mathematical models. These models permit the assessment of variables associated with the process without building experimental setups. In order to achieve this goal, it is necessary to formulate a differential equation that, depending on the number of variables, can be partial or ordinary type. In this context, the present work evaluates the mass balance for an open system from a numerical and mathematical perspective, and then experimentally validates the results obtained. The analytical solutions of the mathematical ...

El mundo va cambiando y con él, el pensamiento y su actuación; a la par, los adelantos científicos y tecnológicos que el mundo contemporáneo y globalizante imponen, los cuales han generado nuevos paradigmas éticos, especialmente en la forma de concebir la ética y a quiénes aplica. De tal manera, se hace importante realizar una exploración a cerca de la bioética animal, toda vez que para nadie es oculto que los animales, en muchas ocasiones, son usados en experimentación, en ejercicios prácticos de laboratorio, en granjas y en hogares son adoptados, pero no se les ofrece una calidad de ...

In the New Era of education, technology has blossomed as an effective tool that promises to evolve and democratize access to knowledge. However, this metamorphosis has also brought to light the relentless technological divide, which threatens to exacerbate existing socioeconomic differences. Inequality in access to technology can lead to significant disparities in educational opportunities, particularly affecting disadvantaged and rural communities.

Trade Agreements (TAs) are instruments crafted and implemented by policymakers with the aim of enhancing trade between countries or regions/economic blocs. In this study, a gravity model was utilized to estimate the effects within a panel of 165 countries, examining Chilean exports across total, agricultural, and manufacturing sectors. The findings largely align with theoretical expectations: the presence of FTAs tends to bolster Chile’s exports to partner nations, with a more pronounced effect observed for FTAs. Notably, FTAs with South Korea, China, and Japan have facilitated ...

Los profesionales en la actualidad, se encuentran inmersos en distintas tensiones de corte social, político, económico y ético, por si fuese poco, la digitalización de la información y el manejo de la misma, ha dado lugar a la transformación de su rol. Por esta razón, se hace necesario que los futuros profesionales, estén preparados para asumir una actitud crítica ante estas prácticas mal intencionadas. Esta investigación, utilizó un enfoque cualitativo para el análisis de las entrevistas que fueron aplicadas a los docentes de comunicación social o periodismo y ciencias computacionales, ...

The study of physical phenomena that include conservative principles is part of the research field of the equations of mathematical physics. To deepen in methods to solve the equations of mathematical physics is a contribution in understanding the modeling of applications in different areas. This research studies the physical phenomenon of heat transport with convection from the viewpoint of modeling with differential equations. The advantage of working with equations is to apply the techniques of mathematical analysis and numerical methods to obtain the temperature function. In the research, ...
