Causes of cetacean stranding and death on the Catalonian coast (western Mediterranean Sea), 2012-2019

2020

The causes of cetacean stranding and death along the Catalan coast between 2012 and 2019 were systematically investigated. Necropsies and detailed pathological investigations were performed on 89 well-preserved stranded cetaceans, including 72 striped dolphins Stenella coeruleoalba, 9 Risso’s dolphins Grampus griseus, 5 bottlenose dolphins Tursiops truncatus, 1 common dolphin Delphinus delphis, 1 Cuvier’s beaked whale Ziphius cavirostris and 1 fin whale Balaenoptera physalus. The cause of death was determined for 89.9% of the stranded cetaceans. Fisheries interaction was the most frequent cause of death in striped dolphins (27.8%) and bottlenose dolphins (60%). Cetacean morbillivirus (CeMV)…

Generalization of Vinen’s equation including transition to superfluid turbulence

2005

A phenomenological generalization of the well known Vinen equation for the evolution of vortex line density in superfluid counterflow turbulence is proposed. This generalization includes nonlinear production terms in the counterflow velocity and corrections depending on the diameter of the tube. The equation provides a unified framework for the various phenomena (stationary states and transitions) present in counterflow superfluid turbulence: in fact, it is able to describe the laminar regime, the first-order transition from laminar to turbulent TI state, the two turbulent states, the transition from TI to TII turbulent states, and it yields a slower decay of the counterflow turbulence than…

Universal vortex formation in rotating traps with bosons and fermions.

2004

When a system consisting of many interacting particles is set rotating, it may form vortices. This is familiar to us from every-day life: you can observe vortices while stirring your coffee or watching a hurricane. In the world of quantum mechanics, famous examples of vortices are superconducting films and rotating bosonic $^4$He or fermionic $^3$He liquids. Vortices are also observed in rotating Bose-Einstein condensates in atomic traps and are predicted to exist for paired fermionic atoms. Here we show that the rotation of trapped particles with a repulsive interaction leads to a similar vortex formation, regardless of whether the particles are bosons or (unpaired) fermions. The exact, qu…

Obligations and Remedies Under a Related Service Contract

2014

Following the model of Directive 2011/83/EU of the 25 October 2011 on consumer rights, the proposed CESL regulation is structured on the basis of sales and service contracts. With regard to service contracts, however, the CESL only regulates those service contracts whose existence is justified by their direct link to sales contracts.

Ceramic ethnoarchaeometry in Western Sardinia: Production of cooking ware at Pabillonis

2015

Ceramic ethnoarchaeology has been used to explore fully the chaîne opératoire and to understand all of the stages and factors involved in pottery production, such as raw material selection or paste recipes used by the potters. This work presents the results of the application of compositional analysis undertaken in the village of Pabillonis (western Sardinia, Italy), the main cooking ware production centre of the island. Pottery and local clays have been characterized using a combination of analytical techniques. By integrating the ethnographic information and the archaeometric approach, it was possible to reconstruct the operational sequence, exploring the relationship between the processi…

Analyse expérimentale et numérique du comportement de véhicules terrestres en présence d'un vent latéral instationnaire

2013

The automotive manufacturers are nowadays more and more interested in crosswind aerodynamics. Indeed, the driver is subjected every day to strong side air flows, for example when overtaking another vehicle or when passing through a lateral wind wall, generated by terrain topography (as in the case of the passage near the empty space between two buildings).The aerodynamic efforts generated in these situations can lead to undesired lateral deviations,which can be dramatic if the driver is surprised. Different experimental studies, reproducing the effects of a dynamic yaw angle, pointed out the issues of the steady methods, commonly used to qualify the vehicle crosswind behaviour. Little is st…

Una lectura de 'La honestidad defendida de Elisa Dido, reina y fundadora de Cartago' de A. Cubillo de Aragón.

2007

La honestidad defendida de Elisa Dido es la única comedia con tema mitológico escrita por Álvaro Cubillo de Aragón. La estructura de la pieza revela la gran habilidad del escritor para construir el argumento, y también los diferentes tonos que predominan en cada una de las tres partes o jornadas que la integran. En general, los personajes están bien delineados, siendo de especial interés la Reina Dido y Tabanco, el gracioso. En lo concerniente a Dido, no muestra la frialdad y la incompatibilidad con la comedia de intriga que le ha atribuido la crítica; por lo que se refiere a Tabanco, es mucho más que el simple tipo de gracioso. Estas consideraciones junto con el final inesperado con el que…

Paleoclimate and bubonic plague: a forewarning of future risk?

2010

Background Human cases of plague (Yersinia pestis) infection originate, ultimately, in the bacterium's wildlife host populations. The epidemiological dynamics of the wildlife reservoir therefore determine the abundance, distribution and evolution of the pathogen, which in turn shape the frequency, distribution and virulence of human cases. Earlier studies have shown clear evidence of climatic forcing on contemporary plague abundance in rodents and humans. Results We find that high-resolution palaeoclimatic indices correlate with plague prevalence and population density in a major plague host species, the great gerbil (Rhombomys opimus), over 1949-1995. Climate-driven models trained on these…
