Giarraffa and Grossa di Spagna naturally fermented table olives: Effect of starter and probiotic cultures on chemical, microbiological and sensory tr…
2014
Abstract This work investigated on the effects of selected starters and of probiotic strains on the evolution of microbiota, on trend of volatile compounds and on the final sensorial traits of green table olives. The olives, belonging to Giarraffa and Grossa di Spagna cultivars, were processed according to Sicilian traditional method and the following samples were obtained: (1) un-inoculated spontaneous olives, control; (2) olives inoculated with probiotic Lactobacillus rhamnosus H25; (3) olives inoculated with commercial probiotic L. rhamnosus GG; (4) olives inoculated with Lactobacillus plantarum GC3 plus Lactobacillus paracasei BS21; and (5) olives inoculated with L. plantarum GC3 plus L…
Neoclerodanes from Teucrium orientale
2004
Abstract Two new neoclerodane diterpenoids, 6-deacetyl-teucrolivin A (5) and 8beta-hydroxy-teucrolivin B (6), were isolated from the aerial parts of Teucrium orientale, along with four already known neoclerodane diterpenoids, teucrolivin A (1), teucrolivin B (2), teucrolivin C (3) and teucrolivin H (4), previously isolated from Teucrium oliverianum. Their structures were elucidated on the basis of spectroscopic evidence and chemical transformations. Compounds 1-3 were assayed for antifeedant activity against Spodoptera littoralis, S. frugiperda and Heliocoverpa armigera. Teucrolivin A was the most potent of the three compounds tested.
Automatic detection and agronomic characterization of olive groves using high-resolution imagery and LIDAR data
2014
The Common Agricultural Policy of the European Union grants subsidies for olive production. Areas of intensified olive farming will be of major importance for the increasing demand for oil production of the next decades, and countries with a high ratio of intensively and super-intensively managed olive groves will be more competitive than others, since they are able to reduce production costs. It can be estimated that about 25-40% of the Sicilian oliviculture must be defined as “marginal”. Modern olive cultivation systems, which permit the mechanization of pruning and harvest operations, are limited. Agronomists, landscape planners, policy decision-makers and other professionals have a grow…
Effects of pyrolysis conditions on the porous structure development of date pits activated carbon
2012
International audience; Activated carbons were prepared from biomass of Algerian date pits for developing efficient and cheap adsorbents in the aim to remove heavy metals from waste water. Carbon adsorbents were obtained following two successive treatments: pyrolysis under dry nitrogen flow and physical activation under wet nitrogen flow. Pyrolysis process was optimized by varying some operating parameters such as temperature, nitrogen flow, heating rate and pyrolysis hold time in order to determine their effects on the porous structure development of date pits activated carbon. Chars obtained from pyrolysis process were activated with the same operating conditions (activation temperature o…
Risultati della lotta biologica contro ilDacus oleae Gmel. a mezzo dell'Opius concolor Sz. siculus Mon.
1965
The Author reports on the essays of artificial biological control of the olive fly (Dacus oleaeGmel.) made by himself andGenduso with the specific parasiteOpius c. siculusMon. found in Sicily. The Authors followingDelanoue's technic have bred theseOpius in laboratory on larvae ofCeratitis capitataWied; so they were able to release: in 1961 — 1000Opius in a small olive plantation near Palermo; in 1962 — 24000Opius in the island of Pantelleria (Sicily); in 1963 — 40000Opius in the island of Salina (Eolic Islands-Sicily); in 1964 — 180000Opius also in the island of Salina.
Environmental impacts of olive oil production: an LCA case study in the Province of Messina (Sicily)

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.…
Flora Ossette’s ‘feminist visibility’ in her translation of Olive Schreiner’s Woman and Labour
2011
La visibilidad del traductor o la traductora se ha convertido en tema obligado en los estudios de traducción desde que Lawrence Venuti editara en 1995 su conocido The Translator’s Invisibility. En la única traducción al castellano de Woman and Labour de Olive Schreiner por parte de Flora Ossette no solo es posible apreciar la voz de la “traductora implícita” (Hermans 1996), sino una voz “explícita”. La traductora interviene activamente en el texto que traduce añadiendo, omitiendo, reorganizando, apostillando o enfatizando las ideas de Schreiner. Además, llevada por los ideales feministas que comparten ambas y por su admiración por la autora sudafricana, se convierte en autora redactando un …
Extracts deriving from olive mill waste water and their effects on the liver of the goldfish Carassius auratus fed with hypercholesterolemic diet
2014
The present research aims to evaluate the beneficial effects of polyphenols derived from waste water from a olive mill, obtained by non-plastic molecular imprinting device, in a hypercholesterolemic diet on Carassius auratus, commonly known as goldfish that was selected as experimental model. The study was conducted with morphological and histochemical analyses and also the data were supported by immunohistochemical analysis. Results show the beneficial activity of polyphenols with a reduction of the damage in the steatotic group, confirming that they may be suggested in the treatment of diseases by lipid accumulation, and used as any addition in feed for farmed fish, in order to improve th…
Nel labirinto della notte
2016
Il testo analizza le fonti letterarie e la drammaturgia dell'opera "Notte per me luminosa" (soggetto/testo di Dario Oliveri - musica di Marco Betta), realizzata su commissione del Teatro Comunale di Modena nell'ambito delle celebrazioni del 500° anniversario della prima edizione dell'"Orlando furioso" di Ludovico Ariosto. Nella parte conclusiva vengono affrontati alcuni problemi legati alla nascita del melodramma e al problema della "mancanza di naturalezza" e del rapporto con il tema aristotelico della "verosimiglianza".
