Lightweight Recoverable Foundations on Suitable Ground
One of the greatest challenges to be faced in the fight against climate change in the
construction sector is the fact that (non-traditional) conventional solutions are routinely accepted
despite their high environmental impact. In particular, reinforced or mass concrete foundations are
used at almost all sites, but they require a large amount of material, involve high emissions (some
toxic), are extremely heavy and cannot be recovered. It is surprising to observe that most recent
constructions in which the environment is taken into account use such foundations.
This paper presents the results of the research carried out on lightweight recoverable foundation
solutions. The aim is to dramatically reduce the amount of material and allow the foundations to be
deconstructed and recycled along with the rest of the building, leaving the land clear for reuse.Postprint (published version
Nanomaterials in the European Union [the quest for a regulatory regime]
Mentre que les nanotecnologies s'espera que porti beneficis importants en molts sectors i contribuir a la competitivitat, hi ha un creixent cos de dades cientÃfiques que indiquin que hi ha motius raonables per témer que els nanomaterials en particular pot donar lloc a els possibles riscos i efectes nocius per a la salut i el medi ambient. El meu objectiu és examinar com la Unió Europea està donant forma a un règim regulatori per nanomaterials: l'opció regulatòria escollida, la legislació vigent aplicable i la seva eficà cia (amb especial atenció sobre REACH buits normatius), la posició adoptada per la els diferents actors en aquest procés i l'evolució prevista legal en el curt termini
Impacte de l’edat i les causes de mort en els canvis de l’esperança de vida en néixer: Catalunya, 1987-2002

El mètode desenvolupat per Arriaga i utilitzat en aquesta anà lisi permet descompondre els canvis observats entre diferents perÃodes (o les diferències entre dos territoris) segons els factors que hi han intervingut
Probing the immune responses to nanoparticles across environmental species. A perspective of the EU Horizon 2020 project PANDORA
Understanding how engineered nanomaterials affect immune responses of living organisms requires a strong collaborative effort between immunologists, toxicologists, ecologists, physiologists, inorganic chemists, nanomaterial scientists and experts in law and risk management. This perspective aims to provide a new viewpoint on the interaction between engineered nanomaterials and the immune defensive systems across living species, gained within the EU Horizon 2020 project PANDORA. We consider the effects of nanoparticle exposure on immune functions in plants, marine and terrestrial invertebrates and their relation to the current state of knowledge for vertebrates (in particular humans). These studies can shed light on the broader perspective of defensive and homeostatic mechanisms (immunity, inflammation, stress responses, microbiota, stem cell differentiation) suggesting ways to: i) perform a comparative analysis of the nanoparticle impact on immunity across model organisms; ii) inspire best practices in experimental methodologies for nanosafety/nanotoxicity studies; iii) regroup and harmonise fragmented research activities; iv) improve knowledge transfer strategies and nano-security; v) propose innovative tools and realistic solutions, thereby helping in identifying future research needs and tackling their challenges

Se propone resolver los problemas planteados por las disposiciones legales en determinadas comunidades del Estado Español en materia del estudio de la enseñanza bilingüe. La primera propuesta consiste en garantizar la posibilidad de recibir la enseñanza en la propia lengua. Las razones son varias: los miles los escolares de habla gallega o euskaldun que no tienen la posibilidad de recibir la enseñanza en su propia lengua; y el éxito de los programas de cambio de lengua hogar-escuela, que presuponen la voluntariedad en la asistencia. En general, se alude a aspectos de actitud implicados en la educación bilingüe. Se destaca que uno de los aspectos decisivos en relación al éxito de los programas de inmersión implica que el escolar no vea amenazada su lengua y su cultura por el hecho de estudiar en una segunda lengua. La segunda propuesta hace referencia al tipo de programas bilingües que deben aplicarse desde la Administración. El mejor medio para introducir una segunda lengua en la enseñanza es mediante los programas de inmersión. Esta propuesta implica la adecuación de los objetivos escolares, asà como la formación permanente del profesorado para que esté a la altura de las nuevas condiciones planteadas.Ministerio Educación CIDEBiblioteca de Educación del Ministerio de Educación, Cultura y Deporte; Calle San AgustÃn, 5 - 3 Planta; 28014 Madrid; Tel. +34917748000; [email protected]

Prefabricated foundations for 3D modular housing
Tridimensional prefabrication of housing has been the object of much literature and few realizations. Finally, enough buildings have been constructed that they can be analysed on site in order to confirm or deny the expectations drawn from integral or nearly integral prefabrication. As we have observed their foundations, it was surprising to find that many or most of their foundations were constructed in si tu, even though prefabricated solutions exist in the industry. This article presents available solutions for prefabricated foundations, it critically describes the foundations of 30 modular housing recently constructed in Catalonia, and it analyses the advisability (or non-advisability) of industrializing the foundations of this type of building.Postprint (published version
