Plastic transformation enterprises are of great importance due to their impact on others belonging to strategic sectors. However, the high consumption of electrical energy in the processing of these materials contributes negatively to the environment. The objective of this research is to determine the indirect emissions of greenhouse gases based on...

Las empresas de transformación del plástico impactan negativamente en el medioambiente pues son grandes consumidoras de energía eléctrica y los desechos generados no son biodegradables, lo que influye en la sostenibilidad. Al respecto, la gestión ambiental según la ISO 14000:2015 contribuye a extender las ganancias a través de la minimización del i...

Actualmente se reconoce que las personas son el activo más importante de una empresa para asegurar los resultados organizacionales, constituyendo un elemento de ventaja competitiva. En este contexto, se torna esencial la mejora de la organización del trabajo que adopta un carácter estratégico para enfrentar los cambios de forma proactiva. La presen...

Objetivo: Lograr el alineamiento estratégico y la mejora continua de la gestión del mantenimiento con enfoque sostenible a través del desarrollo de un cuadro de mando integral en la industria del plástico en Cuba. Métodos y técnicas: Métodos teóricos: análisis y síntesis de los conceptos sobre gestión de mantenimiento con enfoque sostenible y el s...

The COVID-19 pandemic led to the temporary closures of higher education institutions in most countries. In this scenario of uncertainty, it is important to begin to draw the fundamental lines of the way out of this crisis and it is necessary to ensure the highest possible degrees of inclusion and equity. The objective of this article is to develop...

The production of plastics in Cuba at an industrial scale has increased, also developing the transformation of these materials by hand. The workers in this productive sector do not have the theoretical tools necessary to optimally carry out the operations related to the transformation of polymers, nor do they adequately carry out maintenance, which...

This project shows an advance bibliographical revision about biomaterials´ potential application in medicine, specifically in Dentistry, to run new biopolimeric materials tests with academical purposes. Combined investigations about applied didactics to new materials, were carried out at the Stomatology Department of the University of Medical Scien...

The project was conceived with the purpose of evaluating the properties of blends obtained from polyamides and polyesteramides derived from tartaric and succinic acids. The investigation was developed in the characterization, structure and property areas. The miscibility was evaluated by thermal methods, checking the compatibility by means of the m...

A methodology is proposed to measure active electrical properties of polymeric materials focusing specifically ferroelectric response. The samples were obtained in the form of a film from polyvinylidene fluoride taking into account the control of the crystallinity. The specimens were mechanically oriented in an open roller mill at certain temperatu...

This paper was focused on the study of the 5,m nylons (m = 5; 7; 9), due to their potential application as materials with active electrical properties. The investigation has been developed in the characterization and synthesis areas , centering our objective on the analysis of the properties of these polymers for their foreseeable implementation in...
