Presentazione di La politica agricole comunitaria e gli enti locali
1991
il libro svolge una disanima della politica agricola comunitaria (PAC) e del ruolo delle Regioni e autonomie locali
La Nuova Politica di Sviluppo Rurale
2006
Il volume raccoglie in una visione prospettica l'evoluzione del processo di governo della politica agricola dell'unione europea. Ne analizza gli elementi di innovazione e la profondità dei cambiamenti.
L’organisation des circuits courts par les intermédiaires.
2016
The dissertation deals with the institutionalisation of proximity in agri-food markets and the place occupied in this process by non-economic intermediaries (employees of associations, researchers, members of staff from the ministry of Agriculture, advisers of the chambers of agriculture). By varying the scales of investigation, from the national to the departmental level, and by articulating qualitative and quantitative methods, this work points out the paradox that constitute the development of those intermediary agents, as proximity is progressively defined and objectified as a virtuous component of the merchant relationship. On the basis of a sociology of merchant institutions attentive…
Il modello delle politiche agricole
2009
Il modello delle politiche agricole: una complessa architettura che investe il grande sistema dell'unine europea così come i livelli nazionali e regionali. Il funzionamento si articola tra iniziative di programmazione bottom-up, elementi di governo centrale e interfaccia con le istituzioni e i portatori di interesse. Una profonda comprensione costituisce il necessario presupposto per attivare processi e progetti che colgano opportunità e limiti per l'agricoltura regionale.
A supported titanium postmetallocene catalyst: Effect of selected conditions on ethylene polymerization
2011
Ethylene polymerization with a titanium complex [N,N-ethylenebis(3-methoxysalicylideneiminato)titanium dichloride] immobilized on the magnesium support with the formula MgCl2(THF)0.32(Et2AlCl)0.36 was studied. In particular, the effects of polymerization temperature, monomer pressure, and polymerization time on the activity of the catalyst and on the polyethylene properties (molecular weight and its distribution, melting point, crystallinity, and bulk density) were evaluated. The findings of investigations prove that the studied supported titanium catalyst is highly active in ethylene polymerization, and its activity increases with increasing temperature and monomer pressure. Moreover, stab…
Realization of polyaspartamide-based nanoparticles and in vivo lung biodistribution evaluation of a loaded gucocorticoid after aerosolization in mice
2016
Abstract In this study, novel polymeric nanoparticles (NPs) were developed and their potential as carriers for beclomethasone dipropionate (BDP) into the lung after aerosolization was demonstrated by in vivo studies in mice. In particular, these NPs were obtained starting from two polyaspartamide-based copolymers which were synthesized by chemical reaction of α,β-poly(N-2-hydroxyethyl)- dl -aspartamide (PHEA) and its pegylated derivative (PHEA-PEG2000) with poly(lactic acid) (PLA). To obtain nanosized particles, the high pressure homogenization (HPH)—solvent evaporation method was followed by using an organic phase containing both PHEA-PLA and PHEA-PEG2000-PLA (at a weight ratio equal to 1:…
Le pont des Grilles de la Basse-Seille (fin XIVe siècle), ancienne porte d’eau de l’enceinte urbaine de Metz
2017
The bridge des Grilles de la Basse-Seille is one of the last vestiges of the medieval fortification in Metz. It is one of rare examples of fortified bridge in France. Built in the end of the 14th century, it is backfilled in 1911 and only its upper section is visible. An archaeological and historic study was made in 2011 to understand the configuration and the functioning of the bridge in the Middle Ages.
The effect of inbreeding rate on fitness, inbreeding depression and heterosis over a range of inbreeding coefficients
2014
Understanding the effects of inbreeding and genetic drift within populations and hybridization between genetically differentiated populations is important for many basic and applied questions in ecology and evolutionary biology. The magnitudes and even the directions of these effects can be influenced by various factors, especially by the current and historical population size (i.e. inbreeding rate). Using Drosophila littoralis as a model species, we studied the effect of inbreeding rate over a range of inbreeding levels on (i) mean fitness of a population (relative to that of an outbred control population), (ii) within‐population inbreeding depression (reduction in fitness of offspring fro…
Effects of pyrolysis temperature on the hydrologically relevant porosity of willow biochar
2018
Biochar pore space consists of porosity of multiple length scales. In direct water holding applications like water storage for plant water uptake, the main interest is in micrometre-range porosity since these pores are able to store water that is easily available for plants. Gas adsorption measurements which are commonly used to characterize the physical pore structure of biochars are not able to quantify this pore-size range. While pyrogenetic porosity (i.e. pores formed during pyrolysis process) tends to increase with elevated process temperature, it is uncertain whether this change affects the pore space capable to store plant available water. In this study, we characterized biochar poro…
