    Design of a competences based teaching model supported in the integration of repositories and LMS platforms for the automatic control of processes course

    The Automatic Process Control course is part of the Mechanical Engineering, Process Engineering and Production Engineering programs, offered by EAFIT University (Medellin, Colombia). This course has had a number of reforms in recent years, from two academic spaces to one that contains all the content and features them from theoretical and practical components. With this transformation, was generated the need to reduce the time commitment to each of the thematic, causing learning issues in students. For this reason, we have proposed a new reform in the course through the implementation of a content management model based on competences and supported by the integration of repositories and LMS platforms. This model seeks to train students in the skills defined by the courses and because of this, it is important that the learning process provide mechanisms to validate the skill level of each student, taking into account the outcome of the validation should correspond directly to the skills acquired in the training process. To support this model, there are technological tools as platforms for learning management and learning object repositories that support the online teaching and learning processes, and support the use of standards, generating interoperability, reusability, adaptability and scalability content. © 2014 IEEE.

    In this work, TiO2 (Degussa, P-25) supported on calcium alginate pearls was evaluated as catalyst for the photocatalytic inhibition of pathogenic microorganisms. Considering that water samples were taken directly from a natural source, a primary treatment (coagulation, sedimentation and filtration) was executed to remove solids and impurities. Photocatalytic experiments were carried out in two types of laboratory scale equipments, one using an annular UV irradiated reactor and the other a solar UV parabolic collector, both operated in the fluidized bed mode. H2O2 was included to the reactive mixture in order to enhance the photodegradation rate. The Response Surface Methodology and the Box-Behnken experimental design techniques were applied as tools for the optimization of the operational conditions of the UV water purification system. Thus, the influence of UV radiation, TiO2 dose and H2O2 concentration on the faecal and total coliform percentage degradation were statistically analysed. The following optimal operational conditions were found: UV radiation = 310 nm, TiO2 dose = 0.2 g/L and H2O2 concentration = 30 mg/L. After water treatment at optimized conditions, total microorganism growing inhibition was observed. Additional experiments allowed proving the reusability of the immobilized catalyst. © 2014 Science & Technology Network, Inc.
