El Aprendizaje de las habilidades sociales en la universidad. Análisis de una experiencia formativa en los grados de educación Social y trabajo Social

Se presenta una metodología formativa desarrollada en la asignatura de habilidades sociales de los grados otorgados por la Facultad de Educación Social y Trabajo Social Pere Tarrés de la Universidad Ramón Llull (Barcelona-España). A partir del análisis inicial de las competencias sociales de los estudiantes, se establece un plan de trabajo con la finalidad de que mejoren las habilidades sociales necesarias en el contexto profesional. La metodología se plantea como práctica supervisada que requiere la incorporación del estudiante en la organización, desarrollo y evaluación de la asignatura. Para facilitar esa incorporación se ha introducido un recurso narrativo que da sentido a todas las actividades. Se ha utilizado como indicadores de la validez social de esta metodología los datos recogidos a través encuestas de satisfacción de los estudiantes. Los resultados positivos de la experiencia justifican su difusión y su uso en otras universidades.

Fischer-Tropsch Slurry Bubble Column Reactor Modeling

The literature part of the work reviews overall Fischer-Tropsch process, Fischer-Tropsch reactors and catalysts. Fundamentals of Fischer-Tropsch modeling are also presented. The emphasis is on the reactor unit. Comparison of the reactors and the catalysts is carried out to choose the suitable reactor setup for the modeling work. The effects of the operation conditions are also investigated. Slurry bubble column reactor model operating with cobalt catalyst is developed by taking into account the mass transfer of the reacting components (CO and H2) and the consumption of the reactants in the liquid phase. The effect of hydrostatic pressure and the change in total mole flow rate in gas phase are taken into account in calculation of the solubilities. The hydrodynamics, reaction kinetics and product composition are determined according to literature. The cooling system and furthermore the required heat transfer area and number of cooling tubes are also determined. The model is implemented in Matlab software. Commercial scale reactor setup is modeled and the behavior of the model is investigated. The possible inaccuraries are evaluated and the suggestions for the future work are presented. The model is also integrated to Aspen Plus process simulation software, which enables the usage of the model in more extensive Fischer-Tropsch process simulations. Commercial scale reactor of diameter of 7 m and height of 30 m was modeled. The capacity of the reactor was calculated to be about 9 800 barrels/day with CO conversion of 75 %. The behavior of the model was realistic and results were in the right range. The highest uncertainty to model was estimated to be caused by the determination of the kinetic rate.

Tan cerca, tan lejos: Aldo Rossi y el Grupo 2C. Arquitectura, ideología y disidencias en la Barcelona de los 70 = So close, so far : Aldo Rossi and the 2C Group. Architecture, ideology and dissents in the Barcelona of the 70s

The Catalan reception of the 1966 manifestos by Robert Venturi and Aldo Rossi marks the scenario of a breakup: while North America debates about the architectural shape as a linguistic structure, Italy dips its roots in the Modern Movement tradition as an origin for a new temporal and ideological architectural dimension. The first contacts between Rossi and Spain verify this search and allow the Italian to construct common itineraries with some architects from Barcelona. From these exchanges the 2C group will be born, taking part on typical vanguardist mechanisms: they will publish the magazine, 2C. The construction of the city (1972-1985), they will attend the XV Triennale di Milano in 1973 with the Torres Clavé Plan (1971) and the Aldo Rossi + 21 Spanish architects exhibition (1975) while he will organize the three issues of the Seminarios Internacionales de Arquitectura Contemporánea (S.I.AC.) which took place in Santiago, Sevilla and Barcelona between 1976 and 1980. In front of the unfolding of the firsts, the American contacts of Federico Correa, Oriol Bohigas, Lluís Domènech and the PER studio or the teaching work of Rafael Moneo from Barcelona since 1971, allow to draw replica itineraries with the foundation of the magazine Arquitecturas Bis (1974-1985), the organization of the meetings between international publications such as Lotus and Oppositions in Cadaqués (1975) and New York (1977), while stablishing exchanges with members of the Five Architects. Replicas that in 1976 conduct the initial ideological affirmations between Rossi and the 2C group towards irreconcilable distancing. Verifying the itinerary of the journey that the Italian leads from the Italian resistance towards the American backing down is part of the aim of this article
