Further evidence for an early Carboniferous (∼340 Ma) age of high-grade metamorphism in the Saxonian granulite complex
1998
U–Pb and Pb–Pb zircon ages for metamorphic zircons from granulites in the Saxonian granulite complex are reported, using the SHRIMP ion microprobe, conventional multigrain and single-gain techniques and the evaporation method. This is complemented by a Pb–Pb evaporation age for a post-granulite granite emplaced into the schist mantle around the granulites during uplift of the complex. We also demonstrate that zircon ages are not reset during high-grade metamorphism, as commonly argued, but have a very high closure temperature and usually preserve the isotopic composition reflecting the time of their formation. Multifaceted zircons from four granulite samples that probably grew close to the …
About the Influences of Some Major Biotic Drivers on the Population Dynamics in Host-parasite Systems: Interpretative Lessons from an Extended Nichol…
2020
Population dynamics within host-parasite systems in insects is governed by a series of factors, both endogenous and exogenous. Among them, five factors may be considered as major drivers: the respective inherent rates of increase of the host and of the parasite, the level of resource available to the host, the respective immigration rates of the host and of the parasite. While only the first two (the inherent rates of increase of host and parasite) are considered in the original Nicholson and Bailey model, an extended version of the model includes also the other three parameters, thus providing a broader (although still schematic) approach to the host-parasite population dynamics. A brief a…

A funerary perspective on the Bell Beaker period in the Wester Mediterranean Reading the social context of individual burials at La Vital (Gandia, Va…
2013
[EN] The discussion about social dynamics in recent Pre- history is supported by the study of funerary practices. The presence and significance of individual and collec- tive burials in Final Neolithic/Chalcolithic societies in the southeast of the Iberian Peninsula provides new evi- dence for the debate concerning the emergence of social inequalities in this region. Our contribution is based on the recent discovery and excavation of several individual pit burials in domestic contexts at the site of La Vital (Gandía, Valencia). The particularities of the identified burials (different ritual episodes) and their content (Bell Beaker pottery, metal objects, animal offerings) together with an …
The role of light in the emergence of weeds: using Camelina microcarpa as an example
2015
When modelling the emergence of weeds, two main factors are considered that condition this process: temperature and soil moisture. Optimum temperature is necessary for metabolic processes that generate energy for growth, while turgor pressure is necessary for root and shoot elongation which eventually leads to seedling emergence from the soil. Most emergence models do not usually consider light as a residual factor, but it could have an important role as it can alter directly or indirectly the dormancy and germination of seeds. In this paper, inclusion of light as an additional factor to photoperiod and radiation in emergence models is explored and compared with the classical hydrothermal t…
Musical training predicts cerebello-hippocampal coupling during music listening.
2018
Cerebello-hippocampal interactions occur during accurate spatiotemporal prediction of movements. In the context of music listening, differences in cerebello-hippocampal functional connectivity may result from differences in predictive listening accuracy. Using functional MRI, we studied differences in this network between 18 musicians and 18 nonmusicians while they listened to music. Musicians possess a predictive listening advantage over nonmusicians, facilitated by strengthened coupling between produced and heard sounds through lifelong musical experience. Thus, we hypothesized that musicians would exhibit greater functional connectivity than nonmusicians as a marker of accurate online pr…
Análisis molecular de la valoración del intervalo de tiempo óptimo entre la administración de acetato de triptorelina y la punción folicular en los t…
2023
Los fármacos análogos de la GnRH y la hCG han demostrado ser igualmente eficaces en la activación de la cascada de intermediarios de la maduración final ovocitaria que ocurre tras el estímulo ovulatorio. Sin embargo, su mecanismo de acción y por tanto los perfiles hormonales hallados tras el estímulo de los dos fármacos son muy diferentes. El tiempo más adecuado para programar la recolección ovocitaria tras la administración de acetato de triptorelina podría no ser 36 horas como ampliamente se ha pautado en los tratamientos de FIV con hCG. Este intervalo de tiempo es sumamente importante para obtener la mayor proporción posible de ovocitos MII porque procesos como el inicio de la luteinizac…
La costruzione muraria ad Alcamo nell’espansione extra-moenia
2021
Negli ultimi anni, il progressivo passaggio - non solo in ambito strutturale ma anche riguardo ai temi dell’efficienza energetica, della sicurezza antincendio e dell’accessibilità - da norme che prevedono un approccio prescrittivo a norme di tipo prestazionale ha contribuito a demolire il preconcetto di un’inadeguabilità, se non a costo di interventi incongrui o economicamente non sostenibili, del patrimonio edilizio storico rispetto alle istanze di sicurezza, benessere e fruibilità. Questo preconcetto, spesso generato ed alimentato più da una non approfondita conoscenza della costruzione storica che da presupposti fondati, ha contribuito all’abbandono ed al conseguente degrado di gran part…
Cibo e banchetto rituale nella festa della Beata Vergine del Miracolo di Lula
2019
Sul consumo di alimenti nell’ambito delle feste campestri si tenta di ragionare nel contributo, assumendo a caso emblematico i festeggiamenti che annualmente si rinnovano a Lula, centro rurale in provincia di Nuoro, in onore della Madonna del Miracolo. La costruzione del santuario e l’istituzione della festa sono relativamente recenti (1899) e ciò consente di documentare più agevolmente sensi e funzioni di un tipo di occorrenze cerimoniali diffuse in tutta l’isola, che presentano un iter rituale pressoché analogo e che rimandano a un simbolismo rituale proprio di una società tradizionale di tipo agropastorale. L’esempio preso in esame consentirà di rilevare, inoltre, quando e in che misura …
La salud y el acceso a los medicamentos. Un análisis del derecho y la participación de las empresas farmacéuticas
2021
One of the most controverted topics of human rights protection is the role of non-State actors in guaranteeing the rights of individuals since in most cases regional and universal organizations have purely focused their attention on the responsibility of States alone. Accordingly, relevant scholars have urged the need for international law to provide clear and stricter provisions which aim at regulating the conduct of such peculiar actors. Yet, the current international legal realm demonstrates that no legally binding provisions have been adopted and mere soft law instruments have been endorsed at the intergovernmental level. The non-binding character of these instruments provides sufficien…
