Expressing the Beauty of the World. Simone Weil and the Responsibility of Literature
2015
En el presente trabajo se abordan diferentes dimensiones de la relación con la literatura de la filósofa francesa de origen judío Simone Weil (1909-1943). En un primer momento de la exposición se atiende a sus consideraciones sobre la responsabilidad de los escritores que, aunque recorren todo su itinerario, tienen como centro neurálgico su colaboración en la revista Cahiers du Sud durante el periodo de Marsella. Posteriormente, se incide en la presencia de la literatura en su obra, gracias a la influencia de su maestro Alain, quien le enseñó a pensar a través de la escritura. Por último, se hace una breve referencia a la tragedia inacabada,Venecia salvada y a sus poemas, aludiendo a su afi…
Effects of environment and genotype on dispersal differ across departure, transfer and settlement in a butterfly metapopulation
2022
Active dispersal is driven by extrinsic and intrinsic factors at the three stages of departure, transfer and settlement. Most empirical studies capture only one stage of this complex process, and knowledge of how much can be generalized from one stage to another remains unknown. Here we use genetic assignment tests to reconstruct dispersal across 5 years and 232 habitat patches of a Glanville fritillary butterfly ( Melitaea cinxia ) metapopulation. We link individual dispersal events to weather, landscape structure, size and quality of habitat patches, and individual genotype to identify the factors that influence the three stages of dispersal and post-settlement survival. We found that ne…
Modal Analysis of a Reinforced Concrete Frame in Various States of Damage
2005
The purpose of this paper is to report selected results of an experiment in which two, natural size r/c frames were put on shaking table and subjected to a sequence of seismic excitations with increasing intensity interlaced with low level, diagnostic tests. The shaking table experiment aimed at working out new methodology for monitoring vibrations of r/c structures to assess their state. Characteristic decrease of natural frequencies and increase of structural damping was observed and analyzed in detail. It was interesting to note 20 per cent drop in natural frequencies prior to visual detection of any cracks.
The prevalence of depression and anxiety among medical field and non-medical field students in Latvia and Finland
2021
Ievads: COVID-19 pandēmijai ir nopietnas fiziskas un psiholoģiskas sekas. Vispārējās populācijas vidū arī universitātes studenti, šķiet, ir pakļauti garīgās veselības jautājumu ietekmei. Mērķis: Šī pētījuma mērķis ir novērtēt depresijas un trauksmes izplatību medicīnas un nemedicīnas studentu vidū Latvijā un Somijā COVID-19 pandēmijas laikā, un salīdzināt šīs valstis. Metodoloģija: šajā šķērsgriezuma pētījuma tika apkopoti uz aptauju balstītie dati, kā arī trauksmes (Generalized Anxiety Disorder scale-7 jeb GAD-7) un depresijas (The Patient Health Questionnaire-9 jeb PHQ-9) skrīninga anketu dati. Aptauja tika veikta no 2021. gada 29. janvāra līdz 2021. gada 28. februārim. Rezultāts: aptauju…
Comunicació 2.0 i gènere
2009
Internet ha capgirat les formes de comunicació i d’intercanvi d’informació entre les persones: les receptores en el procés comunicatiu són ara també emissores. La conjunció d’aquesta particularitat amb l’aparició i ús d’algunes eines de comunicació (fàcils d’usar i bàsicament gratuïtes) permet parlar d’un fenomen social de gran abast: la comunicació 2.0. Aquest article analitza algunes de les característiques d’aquesta classe d’interacció i centra l’interés de forma particular en certes iniciatives que tenen com a epicentre les qüestions de gènere. La comunicació 2.0 permet la participació activa i directa en el procés, obert i col·laboratiu, de construcció de la identitat pròpia. Així mate…
Design of innovative friction damper devices for earthquake-resilient RC frames with Hybrid Steel-Trussed Concrete Beams
2021
This thesis focuses on the design of innovative friction damper devices for earthquake-resilient Reinforced Concrete (RC) frames realized with Hybrid Steel-Trussed Concrete Beams (HSTCBs). These devices fall within the framework of the recently-proposed low-damage design strategy for structures built in earthquake-prone areas, on the basis of which the structures are designed to experience negligible damage when subjected to seismic events. The comprehensive solution proposed aims at introducing a feasible option for building earthquake-resilient RC Moment Resisting Frames (MRFs), having been proposed very few solutions for this structural scheme so far. Innovative solutions are proposed fo…
A new large scale laboratory: The LEDA research centre (Laboratory of Earthquake engineering and Dynamic Analysis)
2017
Recently, the field of earthquake engineering experienced substantial enhancements due to numerous results of experimental and theoretical researches. Modern technical codes recognized the last advances in this field and provided new solutions for the structural assessment and design of buildings. However, the need for large scale testing is still taking several open questions, especially for the design of civil infrastructures, and experimental activity on full scale specimens has become necessary. This paper presents the main testing facilities of a new research centre, namely the Laboratory of Earthquake engineering and Dynamic Analysis (LEDA) of the University of Enna “Kore”. In particu…
Evaluating the performance of a new picking algorithm based on the variance piecewise constant models
2021
In this paper, a new picking algorithm for the automatic seismogram onset time determination is tested on a dataset of simulated waveforms. We aim at capturing the variations in the performance due to some characteristics of both the seismic event and its detection, which in turn affect some characteristics of the waveforms. We therefore simulate seismic events with different magnitude, and assumed to be detected with different distances from the nearest seismic station. Our tests permit to highlight the scenarios most suitable for our algorithm.
Spatio-temporal log-Gaussian Cox processes on earthquake events
2016
This work presents an application of spatio-temporal log-Gaussian Cox processes for the description of earthquake events. To explain the overall spatial trend, spatial geological information in the study area such as faults and volcanoes are introduced in the model. Moreover, an anisotropic specification of the covariance matrix of the Gaussian process is used to improve the explanation of the phenomenon. We apply and compare different models to explain the seismic events occurred in Alaska over the last decades.
The influence of building interactions on seismic and elastic body waves
2019
We outline some recent research advances on the control of elastic waves in thin and thick plates, that have occurred since the large scale experiment [S. Brûlé, Phys. Rev. Lett. 112, 133901 (2014)] that demonstrated significant interaction of surface seismic waves with holes structuring sedimentary soils at the meter scale. We further investigate the seismic wave trajectories of compressional body waves in soils structured with buildings. A significant substitution of soils by inclusions, acting as foundations, raises the question of the effective dynamic properties of these structured soils. Buildings, in the case of perfect elastic conditions for both soil and buildings, are shown to int…
