Dos pasos superiores en el enlace de la ronda norte de Zaragoza con la autopista del Ebro

La autopista del Ebro, en el itinerario Bilbao-Zaragoza, ha sido objeto de concurso para su construcción y explotación en régimen de peaje, siendo adjudicataria de la misma la empresa Autopista Vasco-Aragonesa, Concesionaria Española, S.A. La concesión de la construcción y explotación del mencionado itinerario, incluía la obligación de construir la Ronda Norte de Zaragoza, que se desarrolla a lo largo de 11 kilómetros entre la Carretera Nacional II, de Madrid a Barcelona, y la autopista de Alfajarín, comienzo del itinerario Zaragoza-Vendrell que completa la Autopista del Ebro. El itinerario total está dividido en once tramos, de los que el décimo se desarrolla entre el enlace de Alagón y Zaragoza, y el undécimo es la propia Ronda Norte de Zaragoza. Estos dos tramos se cruzan prácticamente en ángulo recto a unos 4 kilómetros de la Avenida de Mª Agustín, donde finaliza la Autopista. En el Anteproyecto de la Administración se daba continuidad a la Ronda Norte y a la penetración de la Autopista en Zaragoza, dejando el recorrido Bilbao-Barcelona como un ramal del enlace. La Sociedad Concesionaria introdujo una modificación sustancial en éste, que fue aprobada por la Administración, dando continuidad geométrica y funcional a la Autopista del Ebro, a través del tramo de Ronda Norte, hacia la autopista ya existente Zaragoza- Alfajarín, y con la que estaba entonces en construcción y hoy ya está en funcionamiento, de Alfajarín a Vendrell. De esta forma, la penetración en Zaragoza, del itinerario Bilbao-Zaragoza, se desprende del tronco principal como un ramal de acceso, e igualmente lo hace la propia Ronda Norte, en su dirección hacia la carretera N-II

Regulation of Fission Yeast Morphogenesis by PP2A Activator pta2

Cell polarization is key for the function of most eukaryotic cells, and regulates cell shape, migration and tissue architecture. Fission yeast, Schizosaccharomyces pombe cells are cylindrical and polarize cell growth to one or both cell tips dependent on the cell cycle stage. Whereas microtubule cytoskeleton contributes to the positioning of the growth sites by delivering polarity factors to the cell ends, the Cdc42 GTPase polarizes secretion via actin-dependent delivery and tethering of secretory vesicles to plasma membrane. How growth is restricted to cell tips and how re-initiation of tip growth is regulated in the cell cycle remains poorly understood. In this work we investigated the function of protein phosphatase type 2A (PP2A) in S. pombe morphogenesis by deleting the evolutionary conserved PTPA-type regulatory subunit that we named pta2. pta2-deleted cells showed morphological defects and altered growth pattern. Consistent with this, actin patches and active Cdc42 were mislocalized in the pta2 deletion. These defects were additive to the lack of Cdc42-GAP Rga4. pta2Δ cells show upregulated Cdc42 activity and pta2 interacts genetically with polarisome components Tea1, Tea4 and For3 leading to complete loss of cell polarity and rounded morphology. Thus, regulation of polarity by PP2A requires the polarisome and involves Pta2-dependent control of Cdc42 activity

Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI

Penilaian Kinerja Keuangan Koperasi di Kabupaten Pelalawan

This paper describe development and financial performance of cooperative in District Pelalawan among 2007 - 2008. Studies on primary and secondary cooperative in 12 sub-districts. Method in this stady use performance measuring of productivity, efficiency, growth, liquidity, and solvability of cooperative. Productivity of cooperative in Pelalawan was highly but efficiency still low. Profit and income were highly, even liquidity of cooperative very high, and solvability was good

Search for stop and higgsino production using diphoton Higgs boson decays

Results are presented of a search for a "natural" supersymmetry scenario with gauge mediated symmetry breaking. It is assumed that only the supersymmetric partners of the top-quark (stop) and the Higgs boson (higgsino) are accessible. Events are examined in which there are two photons forming a Higgs boson candidate, and at least two b-quark jets. In 19.7 inverse femtobarns of proton-proton collision data at sqrt(s) = 8 TeV, recorded in the CMS experiment, no evidence of a signal is found and lower limits at the 95% confidence level are set, excluding the stop mass below 360 to 410 GeV, depending on the higgsino mass
