Geostatistical computing of acoustic maps in the presence of barriers
2009
Acoustic maps are the main diagnostic tools used by authorities for addressing the growing problem of urban acoustic contamination. Geostatistics models phenomena with spatial variation, but restricted to homogeneous prediction regions. The presence of barriers such as buildings introduces discontinuities in prediction areas. In this paper we investigate how to incorporate information of a geographical nature into the process of geostatistical prediction. In addition, we study the use of a Cost-Based distance to quantify the correlation between locations.
Managing biotic interactions for ecological intensification of agroecosystems.
2014
9 pages; International audience; Agriculture faces the challenge of increasing food production while simultaneously reducing the use of inputs and delivering other ecosystem services. Ecological intensification of agriculture is a paradigm shift, which has recently been proposed to meet such challenges through the manipulation of biotic interactions. While this approach opens up new possibilities, there are many constraints related to the complexity of agroecosystems that make it difficult to implement. Future advances, which are essential to guide agricultural policy, require an eco-evolutionary framework to ensure that ecological intensification is beneficial in the long term.
Aikuisten avaintaitojen kansainvälinen arviointi – monitahoinen ja jännitteinen
2005
”Osaamista ei tulisi arvioida vain taloudellisen tai sivistyksellisen pääoman tuottajana, vaan myös sosiaalisen oikeudenmukaisuuden ja yksilöiden elämänlaadun näkökulmasta. Monet kansainväliset arvioinnit ovat jo osoittaneet, että niiden kansakuntien, jotka huolehtivat parhaiten heikoimmasta väestönosastaan, kehittyminen on ollut kestävintä niin sivistyksellisesti kuin taloudellisestikin.”
La interpretación de los riesgos naturales y el cambio climático en postgrado. Ejemplos de casos de estudio en la provincia de Alicante (España)
2020
Esta investigación tiene el objetivo de exponer una experiencia didáctica sobre la interpretación de los riesgos naturales y el cambio climático a partir de la propuesta de diferentes estudios de caso de la provincia de Alicante (España). Dicha propuesta se lleva a cabo en la asignatura de Cambio Climático y Riesgo en el Mediterráneo del Máster en Planificación y Gestión de Riesgos Naturales (Universidad de Alicante). Metodológicamente se han expuesto diferentes ejemplos de análisis sobre las temáticas de: 1) Las sequías; 2) La explotación y sangrado de cursos fluviales; 3) Tendencias climáticas; y 4) Medidas de adaptación al cambio climático. Con estos ejemplos se pretende que los discente…
Expansion of rDNA and pericentromere satellite repeats in the genomes of bank voles Myodes glareolus exposed to environmental radionuclides
2021
Abstract Altered copy number of certain highly repetitive regions of the genome, such as satellite DNA within heterochromatin and ribosomal RNA loci (rDNA), is hypothesized to help safeguard the genome against damage derived from external stressors. We quantified copy number of the 18S rDNA and a pericentromeric satellite DNA (Msat‐160) in bank voles (Myodes glareolus) inhabiting the Chernobyl Exclusion Zone (CEZ), an area that is contaminated by radionuclides and where organisms are exposed to elevated levels of ionizing radiation. We found a significant increase in 18S rDNA and Msat‐160 content in the genomes of bank voles from contaminated locations within the CEZ compared with animals f…
Field-Grown and In Vitro Propagated Round-Leaved Sundew (Drosera rotundifolia L.) Show Differences in Metabolic Profiles and Biological Activities
2021
Drosera rotundifolia L. is a carnivorous plant used in traditional medicine for its therapeutic properties. Because of its small size, its collection in nature is laborious and different cultivation methods have been studied to ensure availability. However, only a few studies exist where the lab-grown sundew tissue and field-grown sundew would have been compared in their functionality or metabolic profiles. In this study, the antioxidant and antiviral activities of lab-grown and field-grown sundew extracts and their metabolic profiles are examined. The effect of drying methods on the chromatographic profile of the extracts is also shown. Antioxidant activity was significantly higher (5–6 ti…
Bioactive effects of citrus flavonoids and role in the prevention of atherosclerosis and cancer
2022
Citrus fruits are the main fruits of the Mediterranean diet and have been long recognized for their beneficial effects on human health. Observational studies have shown a significant association between dietary flavonoid intake and reduced risk of cardiovascular and malignant diseases. The beneficial effects of citrus fruits on human health appear to be due to their high content in vitamins, minerals and fibers. In particular, the antioxidant and anti-inflammatory activities have been indicated as some of the mechanisms through which citrus fruits may thwart the development of chronic degenerative diseases such as atherosclerosis and cancer. This review would critically examine the results …
Predator-Induced Plasticity on Warning Signal and Larval Life-History Traits of the Aposematic Wood Tiger Moth, Arctia plantaginis
2021
Predator-induced plasticity in life-history and antipredator traits during the larval period has been extensively studied in organisms with complex life-histories. However, it is unclear whether different levels of predation could induce warning signals in aposematic organisms. Here, we investigated whether predator-simulated handling affects warning coloration and life-history traits in the aposematic wood tiger moth larva, Arctia plantaginis. As juveniles, a larger orange patch on an otherwise black body signifies a more efficient warning signal against predators but this comes at the costs of conspicuousness and thermoregulation. Given this, one would expect that an increase in predation…
Constructions verbales intransitives avec préposition et grammaires françaises pour apprenants hispanophones (1970-2016)
2016
Les constructions verbales intransitives avec préposition posent des problèmes aux apprenants hispanophones, notamment dans le cas des verbes qui admettent en espagnol une construction semblable, mais avec une préposition différente. La description du corpus délimité est centrée sur dix grammaires françaises parues en Espagne de 1970 jusqu’à nos jours. L’apparition de ces constructions dans ces grammaires a été étudiée afin d’envisager d’autres manières d’expliquer ce phénomène en tenant compte du contexte d’apprentissage de l’apprenant hispanophone.
On subjective (and intensifier) I think (that) in parliamentary debate sessions
2018
This paper presents a behavioral analysis of the doxastic form creo (que) as a subjectification modal verb, specifically in its manifestation as a pragmatic intensifier device in a Spanish parliamentary debate. Previous work on creo (que) has suggested that it is indeed an intensifier (Fuentes 2010, Brenes 2015, Cuenca 2015), although many pragmatic approaches to these doxastic verbal forms, not only in the context of Spanish (Hennemann 2012; Albelda, Briz, Cestero, Kotwica y Villalba 2014) but also from other languages (Lakoff 1972; Hooper 1975; Lysvag 1975; Fraser 1975, 1980; Holmes 1984; Caffi 1999, 2004), have classified creo (que) as a marker of attenuation. The goal of this investigat…
