Galois extension of CP-Graded ring extensions

In this paper, we investigate galois theory of CP-graded ring extensions. In particular, we generalize some galois results given in [1, 2] and, without restriction to nor graded fields nor torsion free of the grade groups, we show that some results of graded field extensions given in [3] hold.

The 2004 election in Spain: terrorism, accountability, and voting

In this paper the electoral consequences of the Islamist terrorist attacks on March 11, 2004 are analysed. According to a quantitative analysis based on a post-electoral survey, we show the causal mechanisms that transform voters’ reactions to the bombings into a particular electoral behaviour and estimate their relevance in the electoral results on March 14, 2004

1st National Accessiblity Plan 2004-2012: achieving equal opportunities and full participation through design for all

According to official statistics, disabled people in Spain number 3.5 million and make up 8.8% of the Spanish population. This group of people are increasingly being recognised as members of society with equal rights, and many of their demands are gradually being transformed into solutions that benefit society as a whole. One example is improved accessibility. Accessible built environments are more human and inclusive places, as well as being easier to get around. Improved accessibility is now recognised as a requirement shared by all members of society, although it is achieved thanks to the demands of disabled people and their representatives. The 1st National Accessibility Plan is a strategic framework for action aimed at ensuring that new products, services and built environments are designed to be accessible for as many people as possible (Design for All) and that existing ones are gradually duly adapted.

I Plan Nacional de Accesibilidad 2004-2012

El I Plan Nacional de Accesibilidad 2004-2012 (PNdA) es el mecanismo por el cual la Administración General del Estado se propone acometer de forma ordenada y conjunta con otras administraciones y entidades, la transformación de entornos, servicios y productos, para hacerlos plenamente accesibles a todas las personas, especialmente a aquellas con alguna discapacidad. Por ello la exigencia de desarrollo del Plan surge del articulado de una ley, la Ley 51/2003 sobre igualdad de oportunidades, no discriminación y accesibilidad universal de las personas con discapacidad. Su plazo de ejecución comprende hasta el año 2012.

I Plan Nacional de Accesibilidad 2004-2012: Informe de aplicación. Memoria final

Para arrancar y poner en práctica el Plan se ha considerado la necesidad de desarrollar una “hoja de ruta” (Informe de Puesta en Marcha y Aplicación) de cada una de las acciones consideradas más prioritarias en el primer trienio, a modo de guía para su implementación.

Despliegue y análisis de la cobertura de una red WiMAX basada en IEEE 802.16-2004

Aquest projecte tracta de l’estudi de la cobertura WiMAX basada en la variant 802.16-2004 en la que opera a 3.5 GHz en diferents escenaris d’un campus universitari. Primerament es realitza una introducció general a WiMAX i es defineixen els equips utilitzats. Posteriorment es comença a dur a terme un estudi de la cobertura WiMAX en diferents escenaris: indoor y outdoor per tal de poder extreure models empírics simplificats de path loss a partir de mesures realitzades amb els terminals WiMAX. Per últim, s’introdueix al projecte InterRural del Ministeri d'Indústria, Turisme i Comerç dut a terme durant els mesos Octubre 2007 - Març 2008 amb altres empreses col·laboradores: Telefònica, Hispasat, Gigle i Iber-X. La finalitat del projecte InterRural és comparar diferents tecnologies wireless de banda ample com alternatives per un bucle local ràdio de la última milla. En concret es comparen experimentalment les tecnologies WiMAX i WiFI 802.11a en diferents escenaris: LOS i NLOS.

Tumor necrosis factor (TNF) signaling, but not TWEAK (TNF-like weak inducer of apoptosis)-triggered cIAP1 (cellular inhibitor of apoptosis protein 1) degradation, requires cIAP1 RING dimerization and E2 binding.

Cellular inhibitor of apoptosis (cIAP) proteins, cIAP1 and cIAP2, are important regulators of tumor necrosis factor (TNF) superfamily (SF) signaling and are amplified in a number of tumor types. They are targeted by IAP antagonist compounds that are undergoing clinical trials. IAP antagonist compounds trigger cIAP autoubiquitylation and degradation. The TNFSF member TWEAK induces lysosomal degradation of TRAF2 and cIAPs, leading to elevated NIK levels and activation of non-canonical NF-kappaB. To investigate the role of the ubiquitin ligase RING domain of cIAP1 in these pathways, we used cIAP-deleted cells reconstituted with cIAP1 point mutants designed to interfere with the ability of the RING to dimerize or to interact with E2 enzymes. We show that RING dimerization and E2 binding are required for IAP antagonists to induce cIAP1 degradation and protect cells from TNF-induced cell death. The RING functions of cIAP1 are required for full TNF-induced activation of NF-kappaB, however, delayed activation of NF-kappaB still occurs in cIAP1 and -2 double knock-out cells. The RING functions of cIAP1 are also required to prevent constitutive activation of non-canonical NF-kappaB by targeting NIK for proteasomal degradation. However, in cIAP double knock-out cells TWEAK was still able to increase NIK levels demonstrating that NIK can be regulated by cIAP-independent pathways. Finally we show that, unlike IAP antagonists, TWEAK was able to induce degradation of cIAP1 RING mutants. These results emphasize the critical importance of the RING of cIAP1 in many signaling scenarios, but also demonstrate that in some pathways RING functions are not required.

Inter-Connectedness In The Scottish Economy, 1998-2004

The measurement of inter-connectedness in an economy using input-output tables is not new, however much of the previous literature has not had any explicit dynamic dimension. Studies have tried to estimate the degree of inter-relatedness for an economy at a given point in time using one inputoutput table, some have compared different economies at a point in time but few have looked at the question of how inter-connectedness within an economy changes over time. The publication in 2009 of a consistent series of inputoutput tables for Scotland offers the researcher the opportunity to track changes in the degree of inter-connectedness over the seven year period 1998 to 2004. The paper is in two parts. A simple measure of inter-connectedness is introduced in the first part of the paper and applied to the Scottish tables. It is shown that although the aggregate results might appear to indicate a degree of import substitution was taking place this result is not robust to industrial disaggregation. In the second part of the paper an extraction method is applied to an eleven sector disaggregation of the Scottish economy in order to estimate how interconnectedness has changed over time for each industrial sector. It is shown that for the majority of sectors the degree of interconnectedness with the rest of the Scottish economy has grown for others, in particular Financial Services and Energy and Water Supply it has not.

Disaggregating the Household Sector in a 2004 UK Input Output Table and Social Accounting Matrix by Income Quintiles

This paper disaggregates a UK Input-Output (IO) table for 2004 based on household income quintiles from published survey data. In addition to the Input-Output disaggregation, the household components of a UK Income Expenditure (I-E) account used to inform a Social Accounting Matrix (SAM),have also been disaggregated by household income quintile. The focus of this paper is on household expenditure on the UK energy sector.

Crecimiento del empleo y estructura espacial: el caso de las provincias españolas. 1999 y 2004

En este documento se presenta un estudio acerca de cómo variables de estructura económica y de estructura espacial afectan el crecimiento del empleo en 50 provincias españolas entre los años 1999 y 2004. Para ello, se realiza una estimación global que abarca los sectores de manufacturas y de servicios. Los resultados evidencian economías de urbanización, pero ambigüedad para las economías de localización. Además, variables de estructura espacial como los índices de centralización y concentración resultaron no ser significativos, mientras que el porcentaje de empleo disperso y en subcentros explican ampliamente el modelo además de alcanzar su signo esperado

Terrestrial Lidar investigation of the 2004 rockslide along Petit Champlain Street, Québec City (Quebec, Canada)

Au cours des 240 dernières années, 53 mouvements de versant se sont produits le long du promontoire de Québec, causant la mort de 88 personnes principalement lors de chutes de blocs. En octobre 2004, un petit éboulement a atteint la route dans une zone proche de l'éboulement de 1889 qui a tué 35 personnes et blessé 30 autres. Une image 3D a été créée par l'utilisation d'un scanner Lidar terrestre (SLT). Les sept familles de joints identifiées sont en accord avec les mesures effectuées dans de précédentes études. L'imagerie SLT a aussi permit d'estimer les volumes des instabilités passées et d'en analyser le mécanisme : un glissement rocheux qui affecte des blocs débités en parallélépipèdes par d'autres familles de joints. De plus la zone étudiée montre qu'elle est favorable aux chutes de blocs.
