Breeding-related seasonal changes in immunocompetence, health state and condition of the cyprinid fish, Rutilus rutilus, L.
2003
Seasonal changes in immunocompetence are predicted by the hypothesized trade-off between reproduction and self-maintenance, whereby immune function is a measure of self-maintenance and reproductive effort is seasonally dependent. We examined seasonal patterns in immunological, haematological and body condition parameters for male and female freshwater fish. In two different populations, the relative size of the spleen and the chemotaxic migration activity of head kidney granulocytes decreased immediately before and after spawning, respectively. Those decreases were accompanied by an increase in haematocrit values shortly before and after spawning in both populations and a decrease in the re…
Individual and country-level factors associated with self-reported and accelerometer-based physical activity in old age: a cross-national analysis of…
2022
AbstractThis study aimed to investigate associations between individual-level (personality traits, quality of life) and country-level (gross domestic product per capita, number of policies and action plans for physical activity) factors with self-reported and accelerometer-based physical activity and cross-level interactions among European countries. Based on the Survey of Health, Ageing and Retirement in Europe (SHARE) from 2019–2020, self-reported physical activity (N = 46,617 from 27 countries) and accelerometer-based average acceleration and intensity gradient (N = 855 from 10 countries) were analyzed. Mixed-model regressions with two levels (individuals nested within countries) were us…

AUTOMATIC DETECTION OF SMALL SPHERICAL LESIONS USING MULTISCALE APPROACH IN 3D MEDICAL IMAGES
2013
International audience; Automated detection of small, low level shapes such as circular/spherical objects in images is a challenging computer vision problem. For many applications, especially microbleed detection in Alzheimer's disease, an automatic pre-screening scheme is required to identify potential seeds with high sensitivity and reasonable specificity. A new method is proposed to detect spherical objects in 3D medical images within the multi-scale Laplacian of Gaussian framework. The major contributions are (1) breaking down 3D sphere detection into 1D line profile detection along each coordinate dimension, (2) identifying center of structures by normalizing the line response profile …
A fast BEM model for 3D elastic structures with attached piezoelectric sensors
2009
A fast boundary element model for the analysis of three-dimensional solids with cracks and adhesively bonded piezoelectric patches, used as strain sensors, is presented. The piezoelectric sensors, as well as the adhesive layer, are modeled using a 3D state space finite element approach. The piezoelectric patch model is formulated taking into account the full electro-mechanical coupling and embodying the suitable boundary conditions and it is eventually expressed in terms of the interface variables, to allow a straightforward coupling with the underlying host structure, which is modeled through a 3D dual boundary element method, for accurate analysis of cracks. The technique is computational…
RECUPERARE L’INFRASTRUTTURA :L’HIGH LINE DI NEW YORK, 1929 - 2009.
2010
Designed by James Corner – Field Operation with Diller & Scofidio + Renfro, the High Line elevated Park is set on top of a forsaken elevated railroad structure in the old Manhattan’s meatpacking district. In over 20 years of abandonment, a lush urban wilderness has converted the High Line's tracks into a spontaneous greenway, whose unexpected beauty inspired the new park design, now matching with the huge regeneration of the Hudson Riverfront. The reuse of this abandoned infrastructure, claimed and partnered by the association Friends of the High Line, lean on some characteristic of the former viaduct which passes through buildings and runs nearly 30 feet in the air. Embodying the hybrid be…
A Model for high-cycle fatigue in polycrystals
2018
A grain-scale formulation for high-cycle fatigue inter-granular degradation in polycrystalline aggregates is presented. The aggregate is represented through Voronoi tessellations and the mechanics of individual bulk grains is modelled using a boundary integral formulation. The inter-granular interfaces degrade under the action of cyclic tractions and they are represented using cohesive laws embodying a local irreversible damage parameter that evolves according to high- cycle continuum damage laws. The consistence between cyclic and static damage, which plays an important role in the redistribution of inter-granular tractions upon cyclic degradation, is assessed at each fatigue solution jump…

La información obtenida de este tipo de indagaciones, además de contribuir a la historia de la educación matemática conforma un corpus valioso para la formación de profesores…
Facing the inevitable? : The public telecom monopoly’s way of coping with deregulation
2016
AbstractThe telecommunications industry has gone through a total restructure since the late 1970s, as state-owned national monopolies have given way to listed enterprises and competitive international markets. Scholars have explained wide-ranging privatisation and deregulation at a general level, but what happened to the former state-owned monopolies and how they adapted to the emerging business-oriented environment, has had with less scrutiny. It has been assumed that external factors caused these institutions to adapt a business approach, but did these organisations themselves have any significant power of decision in these processes? This article explains how one of these former state or…
Road to unity? : Nordic economic convergence in the long run
2022
This study examines Nordic economic convergence from the sixteenth to twentieth century respective of the economic leaders, in effect the UK before 1914 and USA thereafter. The paper uses a novel approach of combining the analysis of both GDP and wages. The examination of real GDP per capita suggests that there was a catch-up process in play, both with the economic leaders and among the Nordic states, from the early nineteenth century onwards. However, the examination of the adjusted silver wages suggests convergence among the Nordic economies by the end of the eighteenth century. Therefore, we argue, no single Nordic Model emerged from these development patterns, even though the Nordic sta…
