La investigación tuvo como objetivo calcular la Huella de Carbono en la Facultad de Ciencias Forestales y Ambientales. La metodología utilizada fue la propuesta por el protocolo de Gases de Efecto Invernadero (GHG protocol), elaborado por el Consejo Empresarial Mundial para el Desarrollo Sostenible (WBCSD) y el Instituto de Recursos Mundiales (WRI). Asimismo los factores de emisión se tomó de organizamos internacionales como el Panel Intergubernamental del Cambio Climático (IPCC) entre otros factores de emisión para la cuantificación de las emisiones expresadas en tCO2eq. Se definieron los límites organizacionales y operacionales para la identificación de las fuentes de emisión y posterior clasificación dentro de los alcances (1, 2 y 3). Alcance 1: derivadas por el consumo de combustible, alcance 2: derivadas del consumo de energía eléctrica y alcance 3: derivadas del consum...

Objective: To determine the standard surgical times of the four most common general surgery procedures (unilateral inguinal hernioplasty, bilateral inguinal hernioplasty, umbilical hernioplasty and cholecystectomy) in a second-level hospital and to estimate the probability of extending the time of each of the procedures. Efficiency is a widely studied subject in economics. It involves the need for fewer elements in the production of a certain level of goods and services. Therefore, it is extremely important to consider it in the field of surgery. Materials and methods: An observational, descriptive and retrospective study. It used the operating room records from 2017 to 2019 of the General Surgery service in a second-level hospital. Based on this information, the time required for each procedure was standardized using the mean for each one (umbilical hernioplasty, unilateral or bilateral...

Objective: To develop a mathematical model that incorporates the mortality, incidence and prevalence of Mexico’s most common diseases—ulcer, hypertension, type 2 diabetes mellitus and obesity—in order to improve the accuracy of future medication demand predictions. The model utilizes Markov chains, Monte Carlo simulations, econometric methods and financial projections. Materials and methods: A research design was employed using a predictive mathematical model based on econometric and f inancial approaches, such as Markov chains and Monte Carlo simulations. A simulated population of 20,000 individuals was analyzed over 10 simulation cycles in Excel, where individuals transitioned between the healthy, sick and deceased states. The model included previously researched rates of mortality, incidence and prevalence. Results: Transition tables with probabilities, based on Mexico's most co...

Mechatronics and Robotics (MaR) have recently gained importance in product development and manufacturing settings and applications. Therefore,the Center for Space Emerging Technologies (C-SET) has managed an international multi-disciplinary study to present, historically, the first Latin American general review of industrial, collaborative, and mobile robotics, with the support of North American and European researchers and institutions. The methodology is developed by considering literature extracted from Scopus, Web of Science, and Aerospace Research Central and adding reports written by companies and government organizations. This describes the state-of-the-art of MaR until the year 2023 in the 3 Sub-Regions: North America, Central America, and South America, having achieved important results related to the academy, industry, government, and entrepreneurship; thus, the statistics show...
