    There is a growing concern in the urban transport field about the development of a data set of indicators that would allow to undertake ongoing monitoring and evaluation of current transportation policies, compare data from territories facing the same kind of challenges, identify good practices and strategies to be followed, and strengthen the information, participation and decision-making process. These data set of indicators, known as observatories, are aimed to fulfil stakeholders needs, so that they achieve the precise knowledge to adopt pertinent policies. The Spanish Metropolitan Mobility Observatory, sponsored by the Spanish Ministry of Environment, was launched in 2003 by the Metropolitan Transport Authorities of the major metropolitan areas in Spain, and TRANSyT. Its scope is to identify those elements within urban transport policy packages which have had a more significant impact on mobility (i.e. global transport demand, travel time, modal split,…), and on land use patterns. And its main goal is to serve as basis for Metropolitan Transport Authorities to improve operation of their public transport system, and thus increasing their contribution to sustainable mobility. For itsFor its second edition, based on the year 2003, a set of data from the different Metropolitan Transport Authorities has been collected, in order to: Highlight public transport contribution to improve urban areas and sustainable development - Describe the role of Metropolitan Transport Authorities in achieving an attractive and quality public transport - Monitoring transport supply and demand characteristics, focusing on public transport - Analyse resources dedicated to the public transport system - Describe the financial models used for the public transport system - Highlight the main initiatives and innovations developed by Metropolitan areas This information will be compared to that one from the previous edition, and a statistical analysis will be conducted in order to identify those variables, which are likely to explainresults in most cities.Institute of Transport and Logistics Studies.

    Desde 1996 al 2003, fueron intervenidos 25 pacientes (26 extremidades) de síndrome del túnel radial. Todos los procedimientos fueron realizados por el mismo cirujano y en el mismo hospital con un abordaje postero-externo del túnel radial. Se realizó un seguimiento de todos los pacientes en el tiempo después de la cirugía de 4 meses a 6 años y 4 meses (tiempo medio de 22 meses). Los resultados fueron evaluados según los criterios de Roles y Mausdley; 12 pacientes tuvieron resultados excelentes (46.15%), 9 pacientes buenos (34.61%) y 5 pacientes regulares (19.23%). Once pacientes fueron tratados previamente de epicondilitis lateral (entesitis). La mayoría de los pacientes están satisfechos con la cirugía refiriendo un alivio de la sintomatología y una mejora de la funcionalidad tras la cirugía.Between 1996 and 2003, 25 patients (26 extremities) underwent decompression of the radial tunnel. All procedures were performed at the same surgeon and the same institution using posterior approach. The total 25 patients were available for follow-up evaluation alter surgery (range 4 months - 6 years and 4 months) with average of 22 months. The outcomes was determined using the original criteria of Roles and Mausdley, 12 patients were rated as excellent (46.15%), 9 patients has good results (34.61%) and 5 patients had fair results. Eleven patients were treated previously of tennis elbow. Most of the patients were satisfied and felt subjectively improved by the surgery. They obtained pain relief and better functional status after surgery

    Effects of land use on nocturnal birds in a Mediterranean agricultural landscape.

    Abstract. Knowledge on the effects of land use on community composition and species abundance is crucial for designing realistic conservation strategies, particularly in highly dynamic systems such as Mediterranean agricultural mosaics that are subjected to intensive cultivation. We investigated these effects on the nocturnal bird species occurring in the study area (Stone Curlew Burhinus oedicnemus, Red-necked Nightjar Caprimulgus ruficollis, Barn Owl Tyto alba, Eurasian Scops Owl Otus scops, Little Owl Athene noctua, Tawny Owl Strix aluco, Long-eared Owl Asio otus, Short-eared Owl Asio flammeus and Eagle Owl Bubo bubo) across an agricultural-natural habitat mosaic in Central Spain for three consecutive years. Shares of vineyards, scrubland, herbaceous cropland, water bodies, and roads significantly affected the composition of the nocturnal bird community. Herbaceous cropland and olive groves, which covered 50% of the study area, proved to be neutral for all species. Remnant patches of natural and semi-natural scrubland (around 10% of the study area) and water bodies (only 1.5% of the study area) showed a positive effect on Eagle Owls, Eurasian Scops Owls, Long-eared Owls, and Red-necked Nightjars. Vineyard (35% of the study area) had a negative influence on Eagle Owls, Long-eared Owls, and Eurasian Scops Owls. Our results indicate, first, that the relative extent of land use types was apparently not related with the presence of nocturnal bird species and, second, that natural scrublands and water bodies are key habitats for assuring the persistence of nocturnal birds in agricultural Mediterranean landscapes. Current land planning focused toward land use intensification will likely increase the areas of habitats that are neutral or have adverse effects on nocturnal birds

    Voltage controlled sub-THz detection with gated planar asymmetric nanochannels

    [EN]This letter reports on room temperature sub-THz detection using self-switching diodes based on an AlGaN/GaN heterostructure on a Si substrate. By means of free-space measurements at 300 GHz, we demonstrate that the responsivity and noise equivalent power (NEP) of sub-THz detectors based on planar asymmetric nanochannels can be improved and voltage controlled by means of a top gate electrode. A simple quasi-static model based on the DC measurements of the current-voltage curves is able to predict the role of the gate bias in its performance. The best values of voltage responsivity and NEP are achieved when the gate bias approaches the threshold voltage, around 600 V/W and 50 pW/Hz1/2, respectively. A good agreement is found between modeled results and those obtained from RF measurements under probes at low frequency (900MHz) and in free-space at 300 GHz

    Star-Forming or Starbursting? The Ultraviolet Conundrum

    Get PDF
    Compared to starburst galaxies, normal star forming galaxies have been shown to display a much larger dispersion of the dust attenuation at fixed reddening through studies of the IRX-beta diagram (the IR/UV ratio "IRX" versus the UV color "beta"). To investigate the causes of this larger dispersion and attempt to isolate second parameters, we have used GALEX UV, ground-based optical, and Spitzer infrared imaging of 8 nearby galaxies, and examined the properties of individual UV and 24 micron selected star forming regions. We concentrated on star-forming regions, in order to isolate simpler star formation histories than those that characterize whole galaxies. We find that 1) the dispersion is not correlated with the mean age of the stellar populations, 2) a range of dust geometries and dust extinction curves are the most likely causes for the observed dispersion in the IRX-beta diagram 3) together with some potential dilution of the most recent star-forming population by older unrelated bursts, at least in the case of star-forming regions within galaxies, 4) we also recover some general characteristics of the regions, including a tight positive correlation between the amount of dust attenuation and the metal content. Although generalizing our results to whole galaxies may not be immediate, the possibility of a range of dust extinction laws and geometries should be accounted for in the latter systems as well.Comment: 18 pages, 17 figures, accepted for publication in Ap

    Next generation flow for minimally-invasive blood characterization of MGUS and multiple myeloma at diagnosis based on circulating tumor plasma cells (CTPC)

    Get PDF
    Here, we investigated for the first time the frequency and number of circulating tumor plasma cells (CTPC) in peripheral blood (PB) of newly diagnosed patients with localized and systemic plasma cell neoplasms (PCN) using next-generation flow cytometry (NGF) and correlated our findings with the distinct diagnostic and prognostic categories of the disease. Overall, 508 samples from 264 newly diagnosed PCN patients, were studied. CTPC were detected in PB of all active multiple myeloma (MM; 100%), and smoldering MM (SMM) patients (100%), and in more than half (59%) monoclonal gammopathy of undetermined significance (MGUS) cases (p < 0.0001); in contrast, CTPC were present in a small fraction of solitary plasmacytoma patients (18%). Higher numbers of CTPC in PB were associated with higher levels of BM infiltration and more adverse prognostic features, together with shorter time to progression from MGUS to MM (p < 0.0001) and a shorter survival in MM patients with active disease requiring treatment (p <= 0.03). In summary, the presence of CTPC in PB as assessed by NGF at diagnosis, emerges as a hallmark of disseminated PCN, higher numbers of PB CTPC being strongly associated with a malignant disease behavior and a poorer outcome of both MGUS and MM
