Aeolian Remobilisation of the 2011-Cordón Caulle Tephra-Fallout Deposit: Example of an Important Process in the Life Cycle of Volcanic Ash
2020
Although volcanic eruptions represent short periods in the whole history of a volcano, the large amount of loose pyroclastic material produced, combined with aeolian processes, can lead to continuous, long-lasting reworking of volcanic products. Driven by wind, these processes significantly influence the geomorphology and prolong the impacts of eruptions on exposed communities and ecosystems. Since such phenomena are of interest to scientists from a range of disciplines (e.g., volcanology, atmospheric and soil sciences), a well-defined, common nomenclature is necessary to optimise the multidisciplinary characterisation of both processes and deposits. We, therefore, first describe ash wind-r…
A Band Model of Cambium Development: Opportunities and Prospects
2021
More than 60% of tree phytomass is concentrated in stem wood, which is the result of periodic activity of the cambium. Nevertheless, there are few attempts to quantitatively describe cambium dynamics. In this study, we develop a state-of-the-art band model of cambium development, based on the kinetic heterogeneity of the cambial zone and the connectivity of the cell structure. The model describes seasonal cambium development based on an exponential function under climate forcing which can be effectively used to estimate the seasonal cell production for individual trees. It was shown that the model is able to simulate different cell production for fast-, middle- and slow-growing trees under …
Upper thermal threshold of Lepidurus arcticus (Branchiopoda, Notostraca) in lakes on the southern outreach of its distribution range
2021
Qvenild T, Fjeld E, Fjellheim A, Hammar J, Hesthagen T and Lakka H-K. 2021. Upper thermal threshold of Lepidurus arcticus (Branchiopoda, Notostraca) in lakes on the southern outreach of its distribution range. Fauna norvegica 41: 50–88. The Arctic tadpole shrimp Lepidurus arcticus has a circumpolar distribution and the Scandes (Fennoscandian Mountains) marks its southernmost limit in Europe. Within this area, 391 natural and 88 regulated lakes with L. arcticus have been identified, of which 87% are above the treeline. The lakes hosting L. arcticus decrease in altitude from south to north, which results from its temperature preferences. The majority of the locations are at a lower lake air t…
Targeting the Activin Receptor Signaling to Counteract the Multi-Systemic Complications of Cancer and Its Treatments
2021
Muscle wasting, i.e., cachexia, frequently occurs in cancer and associates with poor prognosis and increased morbidity and mortality. Anticancer treatments have also been shown to contribute to sustainment or exacerbation of cachexia, thus affecting quality of life and overall survival in cancer patients. Pre-clinical studies have shown that blocking activin receptor type 2 (ACVR2) or its ligands and their downstream signaling can preserve muscle mass in rodents bearing experimental cancers, as well as in chemotherapy-treated animals. In tumor-bearing mice, the prevention of skeletal and respiratory muscle wasting was also associated with improved survival. However, the definitive proof tha…
Análisis de la variación y estabilización de los parámetros de programación del implante coclear en relación al tiempo post implantación
2023
La Tesis Doctoral que se presenta lleva por título “Análisis de la variación y estabilización de los parámetros de programación del implante coclear en relación al tiempo post implantación”, y se trata de un estudio retrospectivo sobre la estabilización de estos parámetros durante los primeros 5 años tras la realización de la cirugía. La universalización de la implantación coclear a lo largo de los últimos años ha supuesto cambios importantes en la perspectiva y pronóstico a largo plazo de los pacientes con hipoacusia neurosensorial. El número de pacientes implantados está incrementándose en los últimos años, y esto supone un aumento tanto en el número de cirugías como en el seguimiento pos…

Water and Energy Saving in Urban Water Systems: The ALADIN Project
2016
The ALADIN project was aimed at contributing to environmental and energy sustainability of the urban water system by means of a decision support tool able to allow an evaluation of the energy impact related to each different macro-sectors of urban water cycle highlighting the main energy flows and to assess the system energy balance and identify the possible energy-efficient solutions. Moreover the tool suggests the most efficient actions in reducing water losses. In the present paper the main features of the developed tool are presented. (C) 2016 The Authors.

MR Imaging of Uterus Didelphys Transverse Vaginal Septum Causing Hematometrocolpos and Renal Agenesis
2002
The association of uterus didelphys and unilateral blind vagina with ipsilateral renal agenesis is an infrequent urogenital malformation distinguished by a lesion of the mesonephric duct. In most patients, symptoms are present at the beginning of the menstrual cycle because a transverse vaginal septum on one side obstructs the flow of menses, which consequently collect. Magnetic resonance imaging allows a precise delineation of this congenital abnormality, clearly demonstrating the transverse vaginal septum with hematometrocolpos and uterus didelphys. Extending the magnetic resonance study to the abdomen and employing coronal sections with a wide field of view is important to search for ass…
Perforación en bóveda palatina por consumo de cocaína
2006
El consumo de cocaína va en aumento en la población mundial, los efectos del consumo de esta droga pueden ocasionar efectos secundarios. Se presenta un caso de paciente femenino de 48 años de edad que presenta una úlcera crónica buco-nasal de 2 meses de evolución, la cual le ocasiona problemas para la deglución y fonación. Se discuten la etiopatogenia, diagnóstico diferencial y tratamiento Worldwide, the use of cocaine has an increased over the years, various secondary effects have been described. Here we present a 48 years old female with a 2-month evolution bucconasal ulcer in the hard palate induced by cocaine usage accompanied by swallow and phonation dysfunctions. Ethiopathogenesis, di…
Los derechos de los animales: una visión global del Derecho Animal, ejemplificada con un estudio de caso.
2018
En el siguiente trabajo se pretende dar una visión global del Derecho Animal, se han analizado las corrientes filosóficas actuales, partiendo de diferentes autores y sus ideas en materia de animalismo que han tenido a lo largo de la historia. La postura animalista actual tiene un movimiento predecesor, llamado el Ecologismo, el cual también se analizará, con la finalidad de un entendimiento más profundo de la actualidad filosófica. Como se verá el valor moral va a tener una importancia relevante en este tema, y por ello se ha reflexionado en ese aspecto, los derechos morales y los derechos legales son un punto importante que se ha desarrollado como consecuencia del análisis previo de las te…
