Aquest estudi se centra en el document del CTE que es refereix a les estructuresmetàl·liques d’acer, concretament en els càlculs a tenir en compte a l’hora de realitzar pòrtics d’estructura d’edificació amb perfils metàl·lics laminats. Aquest document és el DB-SE-A, que són les sigles de “Document Bàsic Seguretat Estructural Acer”. Aquest document introdueix algunes modificacions en el mètode de càlcul de les estructures metàl·liques respecte l’antiga norma.La idea d’aquest estudi és fer una comparació entre les dues normes – la vella i ja derogada, i la nova i vigent – i com tracten el càlcul d’esforços en segon ordre i el tractament de les imperfeccions.Com ja s’ha comentat aquest Document Bàsic de la Seguretat Estructural en Acer del CTE (DB-SE-A) substitueix l’antiga norma que es referia al càlcul d’estructura metàl·lica, la NBE-EA-95. En l’aplicació de les accions i el càlcul d’esforços s’utilitza del CTE el Document Bàsic dedicat a les accions en l’edificació (DB-SE-AE) i que substitueix l’antiga NBE-AE-88

Cellular prion protein (PrPC) is a glycosyl-phosphatidylinositol¿anchored glycoprotein. When mutated or misfolded, the pathogenic form (PrPSC) induces transmissible spongiform encephalopathies. In contrast, PrPC has a number of physiological functions in several neural processes. Several lines of evidence implicate PrPC in synaptic transmission and neuroprotection since its absence results in an increase in neuronal excitability and enhanced excitotoxicity in vitro and in vivo. Furthermore, PrPC has been implicated in the inhibition of N-methyl-D-aspartic acid (NMDA)¿mediated neurotransmission, and prion protein gene (Prnp) knockout mice show enhanced neuronal death in response to NMDA and kainate (KA). In this study, we demonstrate that neurotoxicity induced by KA in Prnp knockout mice depends on the c-Jun N-terminal kinase 3 (JNK3) pathway since Prnpo/oJnk3o/o mice were not affected by KA. Pharmacological blockage of JNK3 activity impaired PrPC-dependent neurotoxicity. Furthermore, our results indicate that JNK3 activation depends on the interaction of PrPC with postsynaptic density 95 protein (PSD-95) and glutamate receptor 6/7 (GluR6/7). Indeed, GluR6¿PSD-95 interaction after KA injections was favored by the absence of PrPC. Finally, neurotoxicity in Prnp knockout mice was reversed by an AMPA/KA inhibitor (6,7-dinitroquinoxaline-2,3-dione) and the GluR6 antagonist NS-102. We conclude that the protection afforded by PrPC against KA is due to its ability to modulate GluR6/7-mediated neurotransmission and hence JNK3 activation.

En este trabajo se presenta el análisis de los datos de temperatura, radiación global, radiación difusa y humedad relativa, simultáneos, registrados en la isla Livingston durante las campañas de verano de 1994-95 y 1995-96. Los datos corresponden a dos estaciones, una instalada en la Base Antártica Española Juan Carlos I y otra instalada sobre el Glaciar Johnsons. Se ha establecido la correlación de las variables medidas en la Base con las obtenidas en el glaciar. A su vez, los resultados obtenidos permiten calcular por regresión los correspondientes al glaciar, en las campañas donde no se obtuvieron datos in situ. También, se caracterizan las evoluciones medias diarias de la temperatura, radiación y humedad mediante modelos periódicos. Por último se estudian la relación de la temperatura y nubosidad con respecto a la velocidad y dirección del viento. Algunos de los resultados obtenidos se han comparado con éxito con los obtenidos a partir de los registros de la base antrática de Bellingshausen.

This report aims to analyse how European accounting standards (European System of Accounts ESA-95) are interpreted and applied to the public healthcare sector, from the standpoint of comparative law. Specifically, the study focuses on the application of ESA-95 to healthcare centres in the United Kingdom, France and Germany, with the aim of reaching useful conclusions for the Public Companies and Consortia (EPIC, for their initials in Catalan) in the Catalan Public Healthcare System.
