Este trabajo de investigación tiene como objetivo analizar cómo el concepto de Quality Controlled Logistics puede apoyar el cumplimiento de la calidad y disponibilidad requerida a lo largo de las cadenas de valoración de residuos de frutas y hortalizas. Un tercio de todo el alimento producido es desechado globalmente cada año, siendo los residuos de frutas y verduras los que representan el mayor porcentaje de desecho. Estos residuos pueden ser valorizados mediante diversos procesos con el objetivo de darles un valor agregado. Sin embargo, las estrategias de valoración son afectas por la variabilidad y perecibilidad de estos desechos. Por esta razón, este estudio analiza la aplicación del concepto de quality controlled logistics (QCL) con el objetivo de lidiar con estas dos barreras. Para esto, se realizó una revisión semiestructurada de literatura y entrevistas a tres empresas e...

Los ríos constituyen la principal fuente de ingreso de desechos plásticos a los océanos, principalmente debido a una gestión inadecuada de los residuos sólidos. La presencia de polímeros en los cuerpos de agua genera diversos problemas, como la afectación de la movilidad de las especies, llegando incluso a causar su muerte. Con el tiempo, los polímeros se fragmentan, dando lugar a microplásticos y nanoplásticos, y en ciertos casos, liberan aditivos tóxicos que alteran el equilibrio natural de los ecosistemas acuáticos. En este contexto, el monitoreo de macroplásticos (MPs) en los cursos de agua puede contribuir a una gestión más eficiente de los residuos sólidos. Bajo esta premisa, la presente tesis propuso una estrategia metodológica para adecuar un modelo de inteligencia artificial (IA) basado en deep learning, orientado a la clasificación y cuantificación de MPs y o...

This study analyzes the mechanisms which cause the increment of viscosities in the residuals of heavy oil during the process of transfer and transport. lt has been determined that the increment is dueto the loss of the viscoreducer which is cause by vaporization. These loss of viscosity is a double logarithmic function of the concentration (expressed in volume) of the viscoreducer. lt is recommended to establish a norm of quality control of residuals to achieve a bener behaviour of the product, determining the temperature of 6% of volume and the viscosities from this cut at 1002F and 210°F.
