Separation and identification of piperine and chavicine in black pepper by TLC and GC-MS
2006
Conventional extraction of piperine and its derivatives by stirring the black pepper powder with solvents (ethyl alcohol, chloroform, petroleum ether, diethyl ether, etc.) for 16 to 24 h, or in a Soxhlet device for 16 h, can be replaced by extraction with supercritical fluids (CO 2 , CO + ethanol mixtures) [5, 6], or can be aided by use of microwave irradiation [7]. Separation and identification of the compounds present in pepper (essential oils, alkaloids, etc.) has been achieved by gas chromatography combined with mass spectrometry [8] and by thin-layer chromatography [9, 10].

Conservation genetics of endangered leaf-beetle Cheilotoma musciformis populations in Poland
2012
Steppe-like habitats in Europe are seriously threatened as a result of fragmentation and anthropogenic degradation, at least in western and central parts. Considering the dramatic loss of steppe-like habitats, the evaluation of genetic variation in populations of steppe species is of immediate importance if appropriate conservation measures are to be undertaken. In this paper, we examine the genetic diversity of the highly endangered populations of the leaf-beetle Cheilotoma musciformis, which inhabits only a limited area in south-central Poland, which is geographically isolated from the continuous range of this species. Both mitochondrial and nuclear markers show that the Polish population…
Esse.Re (nel) mondo. Arti visive e rinascita dal 1966 a oggi
2022
Nel complesso quadro distopico della pandemia il saggio prende in esame il progetto espositivo e curatoriale .RE, mostra che non si limita a presentare le ricerche di una selezione di artisti tra i più influenti dei nostri tempi ma si focalizza sull’urgente necessità di problematizzare le dicotomie arte/vita, azione/contemplazione, arte/anti-arte, nella prospettiva di una riflessione critica intorno a una raccolta di opere innovative, tanto nel metodo quanto nel contenuto. Vengono esaminate le opere più significative delle ricerche condotte da Alberto Burri, Saint Clair Cemin, Tony Cragg, Zang Hong Mei, Anselm Kiefer, Jeff Koons, Sol LeWitt, Emil Lukas, Mimmo Paladino, Claudio Parmiggiani, …
Affari e complicità mafiose tra Palermo e Punta Raisi
2014
La storia dello scalo aeroportuale di Punta Raisi – oggi intitolato alla memoria di Giovanni Falcone e Paolo Borsellino – prende avvio nel secondo dopoguerra, in coincidenza con l’incremento del traffico aereo civile nei cieli del capoluogo siciliano, terzo in Italia per numero di transiti di passeggeri e merci, con cifre non più sostenibili dall’aeroporto militare di Boccadifalco. Tutto inizia con la costituzione, nel 1953, del Consorzio Autonomo per l'Aeroporto di Palermo, con l’obiettivo di realizzare il progetto di una nuova infrastruttura civile a pochi passi dal centro urbano, pronta a sostenere la concorrenza con i migliori scali del Paese e a rilanciare la modernizzazione dei commer…
I mercati coperti a Palermo. Architettura e tecnica nella costruzione in ferro tra Ottocento e Novecento
2020
The history of the construction and transformations of the covered iron markets in Palermo, between the nineteenth and twentieth centuries, is very interesting for scholars of historical construction techniques and systems and studies - in addition to the evolution, progress and rethinking - also the assumptions economic and social which made it possible to better organize trade within designed buildings. The essay offers some reflections on two covered markets designed by Giuseppe Damiani Almejda in Palermo and representative of that short and fervent Iron Age that was able to combine the needs of local entrepreneurs, who found a promising opportunity for growth in iron processing, and the…
Using Y-chromosome capture enrichment to resolve haplogroup H2 shows new evidence for a two-path Neolithic expansion to Western Europe
2021
Uniparentally-inherited markers on mitochondrial DNA (mtDNA) and the non-recombining regions of the Y chromosome (NRY), have been used for the past 30 years to investigate the history of humans from a maternal and paternal perspective. Researchers have preferred mtDNA due to its abundance in the cells, and comparatively high substitution rate. Conversely, the NRY is less susceptible to back mutations and saturation, and is potentially more informative than mtDNA owing to its longer sequence length. However, due to comparatively poor NRY coverage via shotgun sequencing, and the relatively low and biased representation of Y-chromosome variants on capture assays such as the 1240 k, ancient DNA…

Diurnal habitat suitability for a Mediterranean steppeland bird, identified by Ecological Niche Factor Analysis
2011
Context The negative effects of agricultural intensification and policies, use of pesticides, fertilisers and mechanised harvesting on several populations of pseudo-steppe birds have increasingly required more detailed and effective habitat suitability models. Distribution models of farmland species are prone to incur recordings of false absence data. Ecological Niche Factor Analysis (ENFA) allows identification of environmental predictors of species distribution by using presence data only. Aims We quantified the diurnal habitat preferences and niche width of one steppe species, the stone curlew (Burhinus oedicnemus), with unfavourable conservations status in a Mediterranean area and recl…
