Les Amazones com a model d´inversió social
2013
La figura de l´Amazona, singularitzada en les diverses reines que apareixen al llarg de la literatura des de l´època grega, es caracteritza per la pertanyença a un estat ginecocràtic que trenca les normes socials tant de l´Antiga Grècia com de les societats cristianes de l´Occident europeu. Normalment aquesta inversió és castigada pels autors, o bé amb la mort al combat, com a l´Antiguitat, o bé amb la derrota amorosa que les fa participar de bon grat de la societat patriarcal establerta. En tot cas, el punt de vista dels autors és força variat i també manifesta una admiració per la valentia d´aquestes dones de naturalesa indòmita, qualitat que les fa encara més atractives als ulls del sexe…
Pharmacological activation of CB2 receptors counteracts the deleterious effect of ethanol on cell proliferation in the main neurogenic zones of the a…
2015
Chronic alcohol exposure reduces endocannabinoid activity and disrupts adult neurogenesis in rodents, which results in structural and functional alterations. Cannabinoid receptor agonists promote adult neural progenitor cell (NPC) proliferation. We evaluated the protective effects of the selective CB1 receptor agonist ACEA, the selective CB2 receptor agonist JWH133 and the fatty-acid amide-hydrolase (FAAH) inhibitor URB597, which enhances endocannabinoid receptor activity, on NPC proliferation in rats with forced consumption of ethanol (10%) or sucrose liquid diets for 2 weeks. We performed immunohistochemical and stereological analyses of cells expressing the mitotic phosphorylation of his…
Le prix des paysages périurbains
2007
L'évaluation économique du prix des paysages périurbains utilise des analyses géographiques (occupation des sols, composition paysagère, distance à des biens paysagers, paysages vus : champ de vision, objets, formes). L'article fait le point sur la littérature en matière de méthode et de résultats et présente l'estimation du prix d'attributs paysagers dans la ceinture périurbaine de Dijon.
Contribution de l'agriculture à l'effet de serre. Importance de l'azote et interactions avec l'ozone
2008
Agriculture contributes to almost 20% of greenhouse gas emissions in France, and the same applies for most EU countries. This is due to a large extent to N2O emission after N fertilizer application, but the emissions are very variable in space and time, due mainly to the variability in environmental conditions. However, the figure of the relationship between agriculture and greenhouse effect is more complex. First a significant fraction of emitted N2O does not occur where N has been applied, but is due to indirect emissions in wetlands or forest where N is transferred by natural pathways. This implies the need to make an assessment at larger scale than the field where N is applied. Many oth…
Trasformazione e riuso dei vuoti urbani: quattro casi studio
2016
Il saggio indaga su contesti urbani consolidati che contengono tracce appartenenti a preesistenze industriali oggi in disuso, ma che costituiscono originali trame urbane da reinterpretare, riqualificare e riutilizzare in alternativa alle nuove espansioni. Il progetto della trasformazione/cambiamento diviene una metodologia d’intervento che richiede approcci, sensibilità e strumenti adeguati, che vanno dal controllo urbanistico a quello architettonico, dalla verifica tecnologica e strutturale a quella sociale e fruitiva. Sono presentate alcune ipotesi progettuali che illustrano come la valorizzazione delle aree industriali possa contribuire alla rigenerazione urbana di interi quartieri o por…
Seasonal and depth related variation of parasite communities of Notacanthus bonaparte Risso, 1840 (Notacanthiformes: Notacanthidae) over the northwes…
2019
Abstract In the last decades fishing activities have spread from coastal to deeper waters with serious effects on the deep-sea ecosystems and its fauna, which are considered to be highly susceptible to these impacts. The implementation of protection measures is necessary, but the knowledge on this biome is scant, and often limited to species of commercial value. To the best of our knowledge, this study is the first survey to describe and analyse parasite infracommunities of the deep-sea fish Notacanthus bonaparte sampled from three bathymetric strata between the upper and lower slope in the western Mediterranean Sea (Balearic Sea, Spain). The aim of this work was to assess the effect of hos…
Sample size in the monitoring of benthic macrofauna in the profundal of lakes: evaluation of the precision of estimates
1996
We discuss here the influence of sample size (number of replicates) on the accuracy and precision of the results when sampling profundal benthos with an Ekman grab according to the Finnish standard, SFS 5076, which is equivalent to the Swedish and Norwegian standards. The aim was to find criteria for choosing a sample size which would avoid any powerful influence of chance on the results without entailing an unreasonable amount of work for monitoring purposes.
ChemInform Abstract: Synthesis and Pharmacological Activities of Novel 3-(Isoxazol-3-yl)-quinazolin-4(3H)-one Derivatives.
2010
Several new 3-(isoxazol-3-yl)-quinazolin-4(3H)-one derivatives were synthesized and tested for their analgesic and antiinflammatory activities, as well as for their acute toxicity and ulcerogenic effect. A few compounds were as active as phenylbutazone in the writhing and acetic acid peritonitis tests. They had a very low ulcerogenic effect.

Crystal fabrics and element impurities (Sr/Ca, Mg/Ca, and Ba/Ca) in shells of Arctica islandica—Implications for paleoclimate reconstructions
2013
Sr/Ca, Mg/Ca and Ba/Ca values are heterogeneously distributed in shells of Arctica islandica. These patterns are largely associated with crystal fabrics (size, habit and orientation of crystals) or the processes controlling them. The outer sublayer of the outer shell layer (oOSL; homogenous and irregular simple prismatic crystal fabrics,) contained element/Ca values up to 62% higher than the inner sublayer (iOSL; crossed-acicular, crossed-lamellar, fine crossed-lamellar and irregular simple prismatic crystal fabrics). A gradual decrease in Sr/Ca and Mg/Ca values was observed from the outer portions of the oOSL toward the oOSL/iOSL transition zone. This chemical shift was accompanied by a gr…
