    Santarém, the paradise of delights: finding Strabo's Moron and its lost island with a new ethymology for Moron

    The city of Mōron mentioned by Strabo would be at either Santarém or Chões de Alpompé, but not at the Alto do Castelo, in Alpiarça. This was the conclusion of a study by the Deutsches Archäologisches Institut in 1982-88. Other authors point to Almeirim, a city eight kilometres south of Alpiarça. Schulten proposes Mōron is the island and castle of Almourol (Tancos). There are at least five hypotheses suggesting where the city of Mōron was. This stems from a restricted understanding of the full meaning of the Greek word kαηά. In this article, I clarify the most used meaning of kαηά, I propose a new etymology for Mōron and retrieve historical information about the place of an old arm of the river Tagus and of the Lagoon of Almeirim, which pointed me the right place of the island mentioned by Strabo, which was close to Mōron. If my suggestions are correct, then these 2,000-year-old riddles are solved

    Clamart, uma solução mais provável para a sua etimologia

    Esta é a tradução para português da carta Clamart, a likelier solution for its etymology DOI: 10.20935/al5129, publicada por Academia.edu, com pequenas melhorias gramaticais. A etimologia de Clamart (Hauts-de-Seine), cidade situada nas proximidades de Paris, atraiu a atenção de vários investigadores ao longo dos últimos 150 anos. Ao analisar as suas hipóteses, nenhum deles teve em conta a topografia dos locais com toponímia semelhante. Um dos investigadores afirmou que Clamart era um topónimo único, quando, na realidade, existem topónimos relacionados em França e noutros países. Tendo em conta os pontos não considerados pelos investigadores anteriores, proponho uma solução etimológica que corresponde à topografia da maioria dos lugares com raiz etimológica semelhante a Clamart. Em Portugal, este artigo propõe uma nova etimologia para a povoação de Galamares

    Co-infection with HPV Types from the Same Species Provides Natural Cross-Protection from Progression to Cervical Cancer

    The worldwide administration of bivalent and quadrivalent HPV vaccines has resulted in cross-protection against non-vaccine HPV types. Infection with multiple HPV types may offer similar cross-protection in the natural setting. We hypothesized that infections with two or more HPV types from the same species, and independently, infections with two or more HPV types from different species, associate with protection from high-grade lesions

    Breakdown in mm-sized discharges : modifying the electric field

    Get PDF
    Due to the small size of the gas gap in micro- and millimeter sized discharges, the presence of a metallic structure in its vicinity profoundly influences the breakdown process. This is a drawback because it makes electrical probing impossible, but can also be an advantage because it allows control over the electric field in the discharge reactor. Optical and electrical measurements were performed in an argon atmosphere at 0.3 or 0.7 bar. A pin-pin geometry was used, with 4 or 7mm between the electrode tips. We found that both active and passive structures influence breakdown, and we demonstrated the differences between the two types and their effects on the breakdown process

    Effect of a high-voltage mesh electrode on the volume and surface characteristics of pulsed dielectric barrier discharges

    Electrical breakdown in a pulsed asymmetric dielectric barrier discharge between a glass-covered mesh electrode and a grounded metal electrode in the air at atmospheric pressure is investigated. Volume discharge forms between the metal tip and the dielectric surface and spreads over the dielectric surface. Breakdown and discharge behaviors depend on the polarity of the charged electrode covered with glass compared to the metal rod electrode. In the case of the dielectric cathode (covered mesh), volume discharge features a stronger and longer-lasting emission. Volume discharge is weaker with outstretched surface discharge developing on the opposite glass electrode sustained by the embedded mesh when the metal rod functions as a cathode. The development and spatial distribution of the surface discharge depend on the relative polarity of the dielectrics caused by the charge deposition of the preceding discharge and is independent of the polarity of the applied high voltage. The discharge emission is brighter for the metal cathode and dielectric anode than for the metal anode, with a branching discharge developing and spreading in a star-like structure along the embedded grid, while a ring-like structure was observed for the metal anode and dielectric cathode. The duty cycle influences the discharge development and properties through the effects of the gas phase and surface pre-ionization

    Disrupted Human–Pathogen Co-Evolution: A Model for Disease

    Get PDF
    A major goal in infectious disease research is to identify the human and pathogenic genetic variants that explain differences in microbial pathogenesis. However, neither pathogenic strain nor human genetic variation in isolation has proven adequate to explain the heterogeneity of disease pathology. We suggest that disrupted co-evolution between a pathogen and its human host can explain variation in disease outcomes, and that genome-by-genome interactions should therefore be incorporated into genetic models of disease caused by infectious agents. Genetic epidemiological studies that fail to take both the pathogen and host into account can lead to false and misleading conclusions about disease etiology. We discuss our model in the context of three pathogens, Helicobacter pylori, Mycobacterium tuberculosis and human papillomavirus, and generalize the conditions under which it may be applicable

    Cerebral thrombolysis in patients with ischemic stroke and heart failure

    Background Heart failure (HF) is common among patients with ischemic stroke (IS), however its impact on outcome after iv-thrombolysis has not been fully determined. Moreover, definition of HF has been recently modified, but majority of stroke studies classified patients regarding an old HF criteria. Thus, the aim of our study was to evaluate the relationship between both, newly and formerly defined HF and the long-term outcome, mortality and the presence of hemorrhagic complications in patients with acute IS treated with iv-thrombolysis. Methods We retrospectively evaluated data from 328 Caucasian patients with IS consecutively treated with iv-thrombolysis. HF was defined according to old and new definition; long-term outcome was assessed with modified Rankin Scale (mRS) score and mortality rate on 90th days after IS. Results The incidence of HF did not differ between patients with favorable (mRS 0–2) and unfavorable (mRS 3–6) functional outcome respectively for the old and for the new definition (10.4% vs. 15.5, p = 0.17; 17.4% vs. 18.1%, p = 0.88) and between those who survived and died within 90 days after IS (11.7% vs. 20.0%, p = 0.27; 17.2% vs. 25.0%, p = 0.38, respectively). Multivariate analysis showed no impact of HF diagnosis on outcome (p = 0.94) or mortality (p = 0.64). Conclusion The presence of systolic HF, defined according to an old and a new definition, does not determine safety and efficacy of cerebral iv-thrombolysis in patients with IS
