Comparison of block size distribution in rockfalls
Ruiz Planas, Montserrat; Corominas Dulcet, Jordi; Mavrouli, Olga Christina
Rock masses detached as rockfalls usually disintegrate upon impact on the ground surface. The knowledge of the Rockfall Block Size Distribution (RBSD) generated by the propagation of the rockfall mass is required for th e analysis of the trajectories o f the blocks, the run - out distances, the impac t energies, the quantitative assessment of the rockfall hazard and for the understanding of the fra g- mentation process . We have measured the volume of the blocks detached in 5 rockfall cases, obtaining the corresponding RBSD. The total volume involved in th ese rockfall events ranges from 2.6 m 3 to 10000 m 3 . The obtained RBS D can be well fitted by power laws with exp o- nents ranging from 0.51 to 1.27. The results suggest that t hese exponents may be related to the height of fall ( potential energy ) and to the pro portion of new fractures generated in the rock mass , among other factors.

It’s time to change! In the new environment of the EHEA (European Higher Education Area), universities are committed to extending and modifying traditional learning techniques in ways that will allow them to incorporate new educational methodologies and settings that are stimulating for lecturers and students alike.
RIMA is a dynamic tool of the ICE-UPC (the Institute of Education Sciences of the Universitat Politècnica de Catalunya, UPC-BARCELONA TECH) that has been set up to group together the initiatives of individuals and established teams in the field of educational innovation and to identify and lay the foundations for desired future education research at the UPC. The RIMA team currently includes 140 members of UPC who are implementing and sharing new practices, proposing and deciding on new methodologies and devising new means for improving teaching and learning techniques and results from students. The aim of RIMA is to help build up a core of knowledge in educational development, knowledge which is rooted in the lecturers’ interest in improving and guiding the learning process. Institutional recognition is also a major concern within RIMA. The efforts made by the groups and members of which it is made up need to be made visible. Conducting and recognising education research is to be one of its priorities.
In the relatively short time -just under two years- since it was set up, RIMA has proved its usefulness in meeting the difficulties in educational innovation enhancement and in seizing new opportunities. This article provides details of the advances made and evaluates the results obtained. It reflects on the way such initiatives may be received and the impact they may have on the design of new EHEA courses and on the institutional objectives of the university.; It’s time to change!

Use of vegetables wastes to remove nickel ions from exhausted electroplating baths
Martínez Martínez, María del Rosario; Florido Pérez, Antonio; Miralles Esteban, Núria; Villaescusa Gil, Isabel; Fiol Santalo, Núria; Poch García, Jordi
The ability of vegetable wastes such as grape stalks and exhausted coffee to remove metals ions from synthetic aqueous solutions has been demonstrated in various studies performed by our research group [Villaescusa et al. 2004; Valderrama et al. 2010]. In this work, the performance of these wastes to remove nickel ions from an exhausted electroplating bath of a metal finishing industry from Barcelona (Spain) has been investigated.
The experiments were carried out at room temperature in packed bed flow-up columns of 250 mm of length and 25 mm internal diameter using grape stalk (GS) and exhausted coffee wastes (EC) particle size 0.5-1.0 mm and 0.8-1.0 mm, respectively. In all experiments nickel concentration was kept constant about 5500 mg dm-3 and pH, flow rate, and bed height were varied in order to predict nickel ions transport in the column. Breakthrough curves were successfully described by Bed depth service time (BDST), Thomas and Yoon Nelson models [Zhe et al. 2013]. Desorption studies were performed by using 0.1 mol dm-3 HCl as elution solution at the same flow-rate used for sorption experiments.
The results obtained demonstrated that, in the studied experimental conditions, variation of initial pH, flow rate and bed height did not lead to significant differences on sorption capacity. The sorbent sorption capacity was higher for GS (20 mg•g-1) than for EC (12 mg•g-1) and metal recovery from the column was close to 50% and 10% for GS and EC, respectively.

Immobilization of selenite onto natural siderite (FeCO3)
Martínez Martínez, María del Rosario; Giménez Izquierdo, Francisco Javier; Pablo Ribas, Joan de
The sorption processes of metals and semimetals on siderite are being studied because of the potential adequacy of the mineral for removing contaminants from natural waters and because of its formation during the reduction of iron(III) (hydr)oxides under anaerobic conditions in the presence of organic matter or bacteria. This transformation could involve the release of contaminants previously sorbed on the iron(III) (hydr)oxides.
In this work, the sorption of selenite on natural siderite (Bordes de Conflent, Lleida, Spain) is experimentally studied and the results obtained are compared to the previous results on selenite sorption on magnetite, hematite and goethite.Results indicate that the process of sorption was very fast; the equilibrium was reached in less than 1 hour, which indicates that sorption will not be kinetically controlled. The experimental data were fitted with a non-competitive Langmuir isotherm, which would indicate that the main process for the decrease of selenite in solution would be its sorption on siderite via monolayer coverage of the solid surface. The values of maximum sorption capacity of siderite obtained at pH 7,1 and 8,0 were 6,9 10-7 and 6,4 10-7 mol g-1, respectively and the same value of Langmuir constant was obtained for both pH values, 4,7 104 L mol-1.
