Empleo de roles de conducta para mejorar el trabajo colaborativo en asignaturas del ámbito ingenieril
(Universidad San Jorge, 2024-01-01) Linares, María; Moreno, Inés; Orcajo, Gisela; Vizcaino, Arturo; Garcia, Alicia; Gomez, Gema; Martín Sómer, Miguel; Pariente, Isabel
Este artículo describe el desarrollo e implementación de un método para organizar el trabajo colaborativo en cursos de ingeniería, maximizando la participación y el aprendizaje en actividades grupales, aprovechando las fortalezas individuales de cada miembro del equipo. Se definen cuatro roles de comportamiento: líder, colaborador, reflexivo o creativo, que se asignan a cada estudiante de manera sencilla a través de un cuestionario que consta de 40 preguntas utilizando Microsoft Forms. Se han observado diferencias en los porcentajes de roles predominantes según el curso y el nivel de estudios en los que se implementa esta metodología. Los estudios más técnicos tienden a tener una mayor proporción de líderes, y a medida que los estudiantes avanzan en sus estudios, las proporciones tienden a igualarse. Finalmente, se destaca que esta metodología ha sido bien valorada por los estudiantes, obteniendo resultados académicos superiores en comparación con actividades grupales anteriores con grupos aleatorios.
This article presents the development and implementation of a method for organizing collaborative work in engineering courses. The method aims to maximize participation and learning in group activities by leveraging the individual strengths of each team member. Four behavioral roles - leader, collaborator, reflective, and creative - are defined and assigned to each student through a straightforward questionnaire consisting of 40 questions, utilizing Microsoft Forms. Differences in the predominant role percentages have been observed based on the course and educational level where this methodology is applied. More technically oriented programs tend to have a higher proportion of leaders, while as students’ progress in their studies, the proportions tend to equalize. Notably, this methodology has received positive feedback from students and has yielded superior academic outcomes compared to previous group activities with randomly formed groups.
Modelling photochemical processes for water disinfection
(Royal Society of Chemistry, 2022-12-21) Casado, Cintia; García, Ángela; Martin Somer, Miguel; Moreno, José; Marugán, Javier
Photochemical processes cover a wide range of technologies for drinking-water and wastewater disinfection, including UV-C, UV/H2O2, photo-Fenton, heterogeneous photocatalysis, solar disinfection, etc. They share the absorption of photons as the activation step triggering the global process. However, significant differences appear depending on the specific technology, including the required wavelength, light sources, reactor design and optimal operational conditions. This chapter focuses on the modelling strategies for the simulation and design of photochemical processes for water treatment, with particular emphasis on the use of sunlight and LED light sources. The necessity of a mechanistic description of the kinetics of the process and its explicit coupling with radiation transport in the system is shown as the best approach for the rigorous design of photochemical reactors. Application of computational fluid-dynamics techniques is also described as a way for the optimal simulation of these multiphysics processes.

Short-term fouling control by cyclic aeration in membrane bioreactors for cosmetic wastewater treatment.
(Elsevier, 2015-12-01) Monsalvo, Victor; Lopez, Jesus; Martín Sómer, Miguel; Fernandez Mohedano, Ángel; Rodriguez, Juan José
Air sparging is extensively used to mitigate membrane fouling in membrane bioreactors (MBRs), which represents an important operation cost in submerged MBR. In this work, the effect of intermittent aeration mode on the membrane fouling has been studied by analysing the influence of the aeration cycle duration in a submerged MBR treating cosmetic wastewater. The long-term filtration at a permeate flux of 8.0 L m−2 h−1 and a constant specific air demand (SAD) of 1.5 m3 m−2 h−1 led to a significant increase in the transmembrane pressure (TMP) after 10 d. The tangential shear showed a limited effect on preventing the deposition of small particles, since carbohydrates and proteins present in the fouling layer were mainly smaller than 1 μm. Flocs showed a low stability under shear stress, which limits the increase in the SAD to avoid undesirable effects over the mixed liquor permeability. The intermittent aeration operation allowed the operation of the MBR under low aeration intensity (low SAD) without compromizing the fouling of the membranes. The use of aeration cycles shorter than 1 min led to an efficient control of fouling, which resulted in a negligible increase in the TMP after 2 h, operating at a permeate flux of 12.0 L m−2 h−1.
