Dam <p><span class="OYPEnA text-decoration-none text-strikethrough-none">The objective of this paper is a theoretical calculation of the mechanical stresses due to nitrogen pressure in an iron vacancy in the temperature range of 600 to 1100 °C and its effect on the swelling phenomenon associated with the high-temperature viscous flow. The method for quantification is theoretical and based on the analysis of experimental data reported in the literature. Two equations related to the variable were generated: swelling index with time and the stress due to nitrogen pressure. Both the variables are described in increasing ways and correlated significantly at the 99% confidence level. The equations include the value of stresses obtained from previous papers for ferrite (Feα) of 621, 2 Kgf/mm2 and for austenite (Feγ) of 727, 6 Kgf/mm2. The overall effect when opposing these values to the average sample cold compression strength of commercial samples, which varies with the corresponding degree of reduction, the final value of this parameter results in the range of 35.2 and 69.6 Kgf/mm2.</span></p> 2023-09-13T19:30:17+00:00 Copyright (c) 2023 Oscar G. Dam Supply chain in the food industry in the meat sector 2023-12-02T04:49:19+00:00 Belen Sarahi Acosta-Balseca Luis Javier Jimenez-Soto Debbie Leandra Valencia-Naranjo Daniela Villacreces-Larrea Fabian Nicolas Viteri-Mesias Amanda Cecilia Zeledón-Estrada <p><span class="OYPEnA text-decoration-none text-strikethrough-none">The meat industry is one of the largest and most important today due to its high consumption, especially in meat from animals such as cows and the derivatives obtained from their processing. This is why it is of utmost importance to design a supply chain that ensures the flow of raw materials efficiently, safely, and humanely. This is how, in this document, the simulation of the beef slaughter and processing process is generated in the FlexSim software to obtain process performance dashboards. In addition, a cleaner production proposal has been included that contains wastewater treatment and the system's energy optimization. This will not only help reduce waste and the use of energy and water but is also intended to ensure the quality of the products and the conservation of the environment.</span></p> 2023-09-13T20:20:02+00:00 Copyright (c) 2023 Belen Sarahi Acosta-Balseca, Luis Javier Jimenez-Soto, Debbie Leandra Valencia-Naranjo, Daniela Villacreces-Larrea, Fabian Nicolas Viteri-Mesias, Amanda Cecilia Zeledón-Estrada Engineering and social responsibility: Challenges and opportunities in high education 2023-12-02T04:49:09+00:00 James Josmell Ojeda Portugal Luis Alonzo Contreras Chavez Deyvin Herlin Cabana Mamani Juan Domingo Banda Cardenas Fredy Morán Cruz <p><span class="OYPEnA text-decoration-none text-strikethrough-none">This study focuses on analyzing university social responsibility in the training of engineers. Engineering students were surveyed and contrasted with social science students to relate higher education with social education. The research was a quantitative and descriptive approach using a non-experimental cross-sectional design. The sample comprised 1023 intentionally selected engineering and social science students. A specific validated scale was applied to assess students' perception of their social responsibility in the university context and ordinary life. The results indicated a medium level of social responsibility with a tendency to be low in the group of university students analyzed. In addition, it was observed that engineering careers should reinforce the social commitment of students.</span></p> 2023-09-13T23:10:05+00:00 Copyright (c) 2023 James Josmell Ojeda Portugal, Luis Alonzo Contreras Chavez, Deyvin Herlin Cabana Mamani, Juan Domingo Banda Cardenas, Fredy Morán Cruz Physics education in the training of engineers for digitized industry 2023-12-02T04:49:00+00:00 Luis Rosales-Romero <p><span class="OYPEnA text-decoration-none text-strikethrough-none">This paper addresses the synergy between engineering and physics education, highlighting how applying physics principles and concepts in engineering projects can significantly enrich STEM education. Innovative pedagogical approaches that foster a deeper understanding of physics by solving practical problems and integrating theory with practice are discussed, thus promoting more effective and meaningful learning in engineering. The main results show that, despite the inclusion of new technological strategies in the engineering career, it is not advisable to eliminate the teaching of physics in the engineering education curriculum and that, on the contrary, it is essential to reinforce these theories.</span></p> 2023-09-13T23:29:01+00:00 Copyright (c) 2023 Luis Rosales-Romero
