Improving the Downwind Sail Design Process by Means of a Novel FSI Approach
2021
The process of designing a sail can be a challenging task because of the difficulties in predicting the real aerodynamic performance. This is especially true in the case of downwind sails, where the evaluation of the real shapes and aerodynamic forces can be very complex because of turbulent and detached flows and the high-deformable behavior of structures. Of course, numerical methods are very useful and reliable tools to investigate sail performances, and their use, also as a result of the exponential growth of computational resources at a very low cost, is spreading more and more, even in not highly competitive fields. This paper presents a new methodology to support sail designers in ev…
Stress au travail et santé : situation chez les indépendants
2011
Dans de nombreux secteurs d’activité, le stress au travail est considéré comme faisant partie des risques pour la santé auxquels peuvent être confrontés les travailleurs salariés et non-salariés ou indépendants. [br/] Le terme de "stress" peut avoir plusieurs définitions en fonction des disciplines médicales, biologiques, médico-sociales, des sciences humaines et sociales qui y font référence. Quelle que soit l’approche disciplinaire, le stress peut être considéré comme un élément d’un processus complexe, à la fois biologique, psychologique et social en réponse à une situation aversive.[br/] Le régime social des indépendants (RSI), qui assure la couverture maladie et de retraite des artisan…
The Role of the Skeletal Muscle Secretome in Mediating Endurance and Resistance Training Adaptations
2021
Exercise, in the form of endurance or resistance training, leads to specific molecular and cellular adaptions not only in skeletal muscles, but also in many other organs such as the brain, liver, fat or bone. In addition to direct effects of exercise on these organs, the production and release of a plethora of different signaling molecules from skeletal muscle are a centerpiece of systemic plasticity. Most studies have so far focused on the regulation and function of such myokines in acute exercise bouts. In contrast, the secretome of long-term training adaptation remains less well understood, and the contribution of non-myokine factors, including metabolites, enzymes, microRNAs or mitochon…
First Evidence of Contourite Drifts in the North-Western Sicilian Active Continental Margin (Southern Tyrrhenian Sea)
2021
We present the results of an integrated geomorphological and seismo-stratigraphic study based on high resolution marine data acquired in the north-western Sicilian continental margin. We document for the first time five contourite drifts (marked as EM1a, EM2b, EM2, EM3a, and EM3b), located in the continental slope at depths between ca. 400 and 1500 m. EM1a,b have been interpreted as elongated mounded drifts. EM1a,b are ca. 3 km long, 1.3 km wide, and have a maximum thickness of 36 m in their center that thins northwards, while EM1b is smaller with a thickness up to 24 m. They are internally characterized by mounded seismic packages dominated by continuous and parallel reflectors. EM2 is loc…
Dynamic assessment of word derivational knowledge: Tracing the development of a learner
2016
The present paper reports on a case study that explored the applicability of dynamic assessment (DA) for promoting learners’ word derivational knowledge in English as a second or a foreign language (L2). One learner’s performance on tasks assessing his word derivational knowledge was measured four times. The first two measurements were conducted before and after three weekly human-mediated DA sessions and the last two, which took place a year and a half later, before and after three weekly computerised DA sessions. Think aloud protocols and interviews were used to trace changes in the learner’s use of strategies and knowledge sources. The results revealed that following the dynamic assessme…
Sex Differences in the Physiological Network of Healthy Young Subjects
2021
Within human physiology, systemic interactions couple physiological variables to maintain homeostasis. These interactions change according to health status and are modified by factors such as age and sex. For several physiological processes, sex-based distinctions in normal physiology are present and defined in isolation. However, new methodologies are indispensable to analyze system-wide properties and interactions with the objective of exploring differences between sexes. Here we propose a new method to construct complex inferential networks from a normalization using the clinical criteria for health of physiological variables, and the correlations between anthropometric and blood tests b…
Developments in the biomechanics and equipment of Olympic cross-country skiers
2018
Source at: http://doi.org/10.3389/fphys.2018.00976 Here, our aim was to describe the major changes in cross-country (XC) skiing in recent decades, as well as potential future developments. XC skiing has been an Olympic event since the very first Winter Games in Chamonix, France, in 1924. Over the past decades, considerable developments in skiing techniques and improvements in equipment and track preparation have increased skiing speed. In contrast to the numerous investigations on the physiological determinants of successful performance, key biomechanical factors have been less explored. Today’s XC skier must master a wide range of speeds, terrains, and race distances and formats (e.g., dis…

L'art. 18 della legge regionale siciliana 6 marzo 1986, n. 9, istitutiva delle Province regionali, ha riconosciuto, in via generale, la possibilità che Comuni e Province possano partecipare a società per azioni.
Lauku diskurss presē latviešu valodā Latvijā (1989-2012)
2014
Promocijas darbā analizēts preses veidotais lauku diskurss un tā izmaiņas sociālekonomisko un citu apstākļu ietekmē no 1989. līdz 2012. gadam. Pētījumā aplūkotas laukiem, to iedzīvotājiem un zemniecībai piedēvētās nozīmes, rezultātus skatot nacionālās identitātes un sociālās atmiņas kontekstā. Teorētiskajā daļā izskaidrota lauku un nācijas saikne, nacionālās identitātes, sociālās atmiņas jēdzieni un komunikācijas loma nācijas re-iztēlošanas procesā. Konteksta uztverei darbu papildina latviešu nacionālās identitātes izpratnes, lauku un lauksaimniecības attīstības, mediju vides un tēmas izpētes līmeņa apraksts. Empīriskie dati iegūti ar diskursa vēsturisko analīzi un kvantitatīvo kontentanalī…
