Sustainable technologies for greenhouse systems
2020
The greenhouse cultivation system in European countries represents one of the most energy-intensive sectors in the agriculture and agro-industry sector. In this regard, renewable energies represent an innovative solution to reduce energy costs and environmental impacts. Both, the energy demands and the economic aspects are analyzed with regard to the main energy users, i.e.: heating and cooling systems, lighting and pumping for irrigation. This work considers the use of solar photovoltaic and thermal energy. The use of semi-closed greenhouses is also considered.
Técnicas de cultivo de la vid y elaboración del vino y del aguardiente en el "Camp de Morvedre" a fines del siglo XVII
1988
EL ARTICULO ANALIZA LAS DIFERENTES LABORES AGRARIAS QUE RECIBEN LAS VIDES DE UNA GRAN EXPLOTACION DEPENDIENTE DEL MONASTERIO DE EL PUIG ENTRE 1671 Y 1691 BASANDOSE EN LOS LIBROS DE CONTABILIDAD. SE ESTUDIA TAMBIEN EL PROCESO DE ELABORACION DEL VINO Y AGUARDIENTE Y EL Destino de la producción. La explotación se caracteriza por un atento cuidado dentro de una técnica tradicional, pero no excesivamente atrasada. El vino se vende en partidas importantes dentro del año agrícola, y únicamente si es malo o se acumulan excedentes se opta por destilarlo.
High Performance Liquid Chromatografy-Mass Spectrometry based chemometric characterization of olive oils
2005
In this study the effective discrimination of extra virgin olive oils is described using HPLC-MS, combined with chemometric evaluation. The presented method is simple since the diluted oil sample is directly injected into the system, without any preliminary chemical derivatization or purification step. Separation of diacylglycerols, triacylglycerols and sterols occurs within 20 min and is achieved using an octadecyl-silica column. Detection is performed by positive APCI mass spectrometry which provided sensitivity to detect over 50 compounds in the sample. After extraction of data, stepwise discriminant function analysis is used to select the variables with the highest discriminative power.…
Step by step – The neolithisation of Northern Central Europe in the light of stable isotope analyses
2018
Abstract There is a long lasting debate on the nature of the neolithisation process in the northern European lowlands and in southern Scandinavia. Early evidence of domesticates and crop cultivation indicate a transition to farming in this area during the late 5th millennium cal BC. However, there is limited information how this process took place and to what extent the new economy was adopted during the subsequent centuries. Here we present new results of more than 50 stable isotope samples of human remains (13C/15N) from northern Central Europe covering the period from the Mesolithic to the early Bronze Age. They show a high relevance of aquatic resources during the early Mesolithic. Food…
Biofonctionnements des sols tropicaux et mode de gestion des terres
2000
L'effet de la symbiose mycorhizienne sur la croissance du mil a été étudié en conditions contrôlées. Le sol collecté au sud du Sénégal dans un champ cultivé et dans une jachère de 17 ans a été mélangé et stérilisé. Il a ensuite été inoculé avec le #Glomus aggregatum$. La croissance de plants de mil cultivés sur ce sol a été comparée à une série témoin, cultivée sur sol non inoculé. La mycorhization des racines de mil a été faible. Elle n'a pas provoqué de réaction de stimulation de croissance. Cette absence de réponse pourrait s'expliquer par l'utilisation d'une souche exotique et non d'une souche indigène de champignon mycorhizien. (Résumé d'auteur)
Revised annual post-market environmental monitoring (PMEM) report on the cultivation of genetically modified maize MON 810 in 2013 from Monsanto Euro…
2015
Question number: EFSA-Q-2015-00432On request from: European Commission; Following a request from the European Commission, the Panel on Genetically Modified Organisms of the European Food Safety Authority (EFSA GMO Panel) assessed the results of the general surveillance activities contained in the revised annual post-market environmental monitoring (PMEM) report for the 2013 growing season of maize MON 810 provided by Monsanto Europe S.A. The supplied data do not indicate any unanticipated adverse effects on human and animal health or the environment arising from the cultivation of maize MON 810 cultivation in 2013. Similar methodological shortcomings to those observed in previous annual PME…
Madre Nostra delle Selve
2015
La letteratura folklorica europea abbonda di leggende relative ad apparizioni della Vergine e a rinvenimenti di immagini mariane in prossimità o tra le stesse fronde di alberi e all'interno di selve, nonché di notizie sull’origine dei relativi culti. Numerose attestazioni ricorrono anche in Italia, rivelando in diversi casi, pur in presenza di trasformazioni delle prassi rituali, una persistente vitalità cultuale. Non diversamente può dirsi per la Sicilia. Nell’Isola si susseguono, durante tutto il corso dell'anno, pellegrinaggi, rosari, messe solenni e processioni in onore della Vergine. Numerosi sono i culti santuariali che superano la dimensione locale e tra questi quelli della Madonna d…
Compari di san Giovanni. Matrimoni e battesimi nella mafia dell’agro palermitano negli anni Venti
2017
Matrimonies and Baptisms in the Mafia of Palermo during the Twenties Historical sources have demonstrated that, since the origins of the Mafia, it has always had strong links with religion. Often, mafiosi appear to conform to Christian values: they usually go to Mass and celebrate baptisms and marriages, or tend to use religious symbols, such as crosses or holy pictures. They favour the preservation of a traditional society, outwardly based on hierarchical values and family unity. However, their ceremonies and family ties are used to reinforce criminal alliances, often ratified by comparaggio, the strong tie that arises from baptism. This article, based mainly on police and judiciary source…

Phenological and agronomical evaluation of chamomile in Mediterranean environments
2008
Chamomile (Chamomilla recutita (L.) Rausch.) is an annual crop, known worldwide as one of the major medicinal herbs. Its flower heads are reported in the official Pharmacopoeia of 26 countries. In order to evaluate the suitability of chamomile to a low-input field cropping management into a semiarid Mediterranean environment, a long-term research activity has been carried out in the experimental farm “Sparacia” (Cammarata – AG – Sicily); hereby we report the results obtained on plants grown in self-seeded experimental plots in 2007/08. Plants development was observed from November 2007 up to (visually assessed) flowers appearance. Blooming started in middle February, and in middle April (af…
