    Comparative study of the environmental risks associated with construction and demolition waste deposits
    (2023-06) Machado, Gladys; Pacheco, María Susana; Alvarez Dávila, Manuel; Suarez, Solange
    Any contingency that is considered to cause deterioration or destruction of the environment must be considered an environmental risk. Its evaluation allows estimating the way, magnitude and particular characteristics of a probable environmental damage. In the case of construction and demolition waste deposits (WCD), an effective environmental management has as a fundamental link the evaluation of the environmental risk, which will be identified according to the frequency and probability of occurrence and the seriousness of the consequences once produced. Its recognition and registration represents the integration stage that makes it possible to determine it quantitatively with the objective of applying the occasional preventive measures to avoid the imminent potential danger that, due to exposure, would produce adverse effects and whose intensity and duration will bring undesirable consequences. Furthermore, an efficient management of this waste should begin in the very first stage of the work, carrying out a simple classification of it as reusable, recyclable on site, recyclable off site and non-reusable [1]. In any case, the presence of these discarded materials, scattered on the surface of a soil, modifies its morphological characteristics and with it the ephemeral or permanent alteration of the different physicochemical processes, as well as those inherent to the ecosystem and its biological diversity. On the other hand, a high and sustained load of pollution agents in the soil can exceed the retention, fixation and adsorption capacity, given the properties of each particular soil, and be available to be transported to groundwater. However, the agents involved can be chemical, physical, biological, forms of energy; and also be released into air, soil or surface water resources [2]. Thus, the objective of this work was the quantitative comparison of the physicochemical characteristics of a base soil with its contaminated counterpart ten years ago and its current leachate, which were called A0, A10 and A22 soil, respectively. Having selected and prepared the samples for analysis, the materials were characterized and the risks that they could cause were assessed. The soils that were modified by the presence of WCD were affected in terms of the different residence times, since they presented evident, considerable and interesting variations respect to the soil taken as reference, A0, whose sample was not altered in terms of density, pH, salinity, ion exchange capacity, organic matter content, development of microorganisms, among others.

    Formación práctica en contexto de pandemia para ingeniería química : desafíos, fortalezas y debilidades
    (2021) Machado, Gladys; Alvarez Dávila, Manuel; Suarez, Solange; Legarto, María Leticia; Cappello, Viviana Beatriz;
    Tal cual lo indicara Darwin, especie que no se adapta perece. En las actuales circunstancias de pandemia por COVID-19, y el correspondiente aislamiento social, la UTN FRLP tuvo que adaptar los procesos de enseñanza y aprendizaje para garantizar la continuidad educativa, a través de la modalidad virtual; ampliando entonces la capacidad del Campus Virtual Global para el uso continuo e indiscriminado en cuanto al tiempo para la actividad docente. Y tan significativo es la incorporación del conocimiento como su aplicación representada por la formación práctica en las asignaturas Químicas para la carrera de Ingeniería Química. He ahí el desafío de custodiar los procesos con la correcta elección de recursos y herramientas pedagógico-didácticas más adecuadas para su desarrollo. Entonces, el objetivo del presente trabajo fue investigar en forma estadística el desempeño académico de los estudiantes y las fortalezas y debilidades derivadas de la tecnología educativa elegida. Observándose que hubo afectación del mismo, aunque la existencia de otras variables también pudieren ser responsables, tales como la conectividad, la calidad del servicio de Internet, los equipos utilizados, entre otras. Condicionantes sociales que también se han tenido en cuenta desde el punto de vista humano y de contención hacia el discente. Así, la realización de actividades prácticas mediante recursos virtuales fue beneficiosa pedagógicamente y posibilitó el acceso a una herramienta con descripciones claras, sencilla de manejar, sin límite de tiempo e inclusiva. Sin embargo, un numeroso porcentaje de alumnos tiene preferencia por la actividad práctica de forma presencial, como así también el cursado.
