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...

With the arrival of the COVID-19 Pandemic, many activities have been modified, among which are work, student, cultural, and recreational activities. Likewise, the World Health Organization (WHO) has commented that the transmission of this virus is from person to person, as well as the possibility that this virus survives on surfaces for several hours. Given this, the governments of each country have seen the need to propose measures of social isolation or immobilization in order to stop this disease. On the other hand, the arrival of the pandemic has also increased the greater amount of use of products in hospitals, which must be constantly discarded, that is, the waste management system plays an important role there. Years ago, the solid waste and biopollutant management system was inefficient and scarce, which made the pandemic worsen the situation. The objective of this systematic res...

La presente revisión de literatura propone describir los beneficios de la implementación de las 5’s en la industria manufacturera, para tal fin se recopiló 50 artículos de revistas indexadas a bases de datos como Scopus, Latindex, Crosreff, Ebsco, Dialnet, Redalyc, entre otros; que fueron publicados en idioma ingles y español, y entre los años 2017 y el 2022. Del análisis de contenido quedó establecido que la implementación de la metodología en todos los casos mejora la productividad, además de mejorar la seguridad del entorno de trabajo, reduce los costos, la accidentabilidad, mejora las relaciones humanas en el trabajo, incrementa el compromiso y propicia un ambiente amigable de trabajo. Asimismo, ha sido incluida como herramienta principal y base para la implementación del Lean Manufacturing y el TPM, pero interactúa muy bien con otras herramientas como la Gestiòn de A...
