Fatty Acids as Biomarkers of the Production Season of Caciocavallo Palermitano Cheese
2021
Simple Summary In the Mediterranean environment, climatic variability determines a discontinuity in the forage availability of pastures. Caciocavallo Palermitano is a cheese obtained from the milk of the Cinisara cattle breed, mainly raised on pasture. The present study investigated the fatty acid profile of cheeses produced in two typical farms in the four seasons of the year, with the aim of identifying specific fatty acids that can be used as biomarkers to discriminate the productions obtained in the different seasons, in order to economically enhance those seasonal productions that have better health characteristics. The results revealed the possibility of distinguishing spring producti…
Bach fra le stelle
2014
Il testo costituisce la postfazione del volume di Ramin Bahrami "Il suono dell'Occidente. Le opere musicali che hanno fatto la nostra civiltà" (Mondadori 2014) e prende le mosse dal concetto di "Enciclopedia" per tracciare una riflessione storico-musicologica sulle 14 composizioni che Ramin Bahrami ssume quali imprescindibili punti di riferimento per una visione d'insieme della cultura musicale occidentale: da Monteverdi fino a Schoenberg, passando per Vivaldi, Bach, Wagner, Verdi, Mahler, Rakhmaninov e Stravnsky.
Development of combustion dynamics at co-combustion of straw with wood

Paliotti d’altare in fili di paglia delle chiese cappuccine della Sicilia occidentale
2018
Degna di nota è l’abilità di alcuni religiosi francescani nell’eseguire opere ornate con fili e frammenti di paglia, materiale povero per eccellenza, facilmente flessibile e dal colore simile all’oro. Pochi nomi emergono nel panorama artistico siciliano relativamente alla lavorazione di paliotti d’altare ornati con tale materiale, uno di questi è Padre Antonino da Bisacquino, ma meritano di venire alla ribalta insieme alle loro creazioni. Very interesting is the ability of some Franciscan religious in executing works adorned with threads and straw fragments, a poor material, easily flexible and with a color similar to gold. Few names emerge in the Sicilian artistic panorama regarding the cr…
Simple Sequence Repeat Marker Development and Mapping Targeted to Previously Unmapped Regions of the Strawberry Genome Sequence
2011
The genome sequence of the woodland strawberry (Fragaria vesca L.) is an important resource providing a reference for comparative genomics studies and future sequenced rosaceous species and has great utility as a model for the development of markers for mapping in the cultivated strawberry Fragaria ×ananassa Duchesne ex Rozier. A set of 152 microsatellite simple sequence repeat (SSR) primer pairs was developed and mapped, along with 42 previously published but unmapped SSRs, permitting the precise assignment of 28.2 Mbp of previously unanchored genome sequence scaffolds (13% of the F. vesca genome sequence). The original ordering of F. vesca sequence scaffolds was performed without a physic…
Straw mulch as a sustainable solution to decrease runoff and erosion in glyphosate-treated clementine plantations in Eastern Spain. An assessment usi…
2019
[EN] In many Mediterranean areas, citrus orchards exhibit high soil loss rates because of the expansion of drip irrigation that allows cultivation on sloping terrain and the widespread use of glyphosate. To mitigate these non-sustainable soil losses, straw mulch could be applied as an efficient solution but this has been poorly studied. Therefore, the main goal of this paper was to assess the use of straw mulch as a tool to reduce soil losses in clementine plantations, which can be considered representative of a typical Mediterranean citrus orchard. A total of 40 rainfall simulation experiments were carried out on 20 pairs of neighbouring bare and mulched plots. Each experiment involved app…
Ecological role of mycotoxins produced by Fusarium graminearum : consequences of the presence of deoxynivalenol (DON) in crop residues on the soil mi…
2012
Fusarium graminearum is a plant pathogenic fungus, causing devastating disease “Fusarium head blight” (FHB) in cereals including wheat and maize. It also contaminates the grains with mycotoxins including deoxynivalenol (DON) which are toxic to human and animals. This disease has resulted in the serious losses in grain yield and quality. We established through a first bibliographic review that during off season fungus survives saprophytically on the crop residues (ecological habitat) and serves as primary inoculum for the next season crop. However, we noticed also that the literature was poor about the role mycotoxins could play in the establishment of F. graminearum in such a habitat. The m…
The effects of biomass co-gasification and co-firing on the development of combustion dynamics
2018
Abstract Effects of wheat straw co-firing with gas (propane flame) and co-gasification/co-combustion with wood pellets on the development of thermo-chemical conversion of biomass pellets and on heat energy production were experimentally studied and analyzed with the aim to improve the gasification/combustion characteristics and the applicability of wheat straw as an alternative energy source for cleaner heat energy production. The results suggest that the wheat straw co-firing with propane provides an enhanced thermal decomposition of pellets with more complete combustion of volatiles increasing thus the heat output at thermo-chemical conversion of wheat straw and the produced heat energy p…
Efficiency of acetic acid and formic acid as a catalyst in catalytical and mechanocatalytical pretreatment of barley straw
2016
Abstract In this study, the potential of organic acids (formic acid, acetic acid) in a catalytical and mechanocatalytic conversion of lignocellulosic barley straw to valuable sugars is explored using sulfuric acid as a reference. Acid-catalyzed hydrolysis has been carried out with acid-impregnated samples as well as unmodified barley straw. In the mechanocatalytical approach, pretreatment consists of impregnation with the acid catalyst and mechanical treatment by ball milling following chemical hydrolysis. Straw samples and residues were analyzed by Fourier transform infrared spectrometry (FT-IR) whereas hydrolysate analysis was based on total reducing sugar (TRS) determination following th…
Productivity of an Atriplex halimus shrubbery and effects of grazing on lambs
2009
The objectives of this study were to 1) evaluate the productivity and forage quality of Atriplex halimus, 2) investigate modifications to shrub structure induced by grazing, and 3) assess live weight changes in lambs grazing on A. halimus with and without a feed supplement (wheat straw ± barley grain). The results showed that A. halimus had low productivity (approximately 1000 kg DM ha–1) but high tolerance to grazing by lambs, although minor modifications in plant structure due to grazing were observed. Lambs grazing A. halimus as a sole diet lost weight (about 60 g lamb−1 d–1; P < 0.01), probably as a consequence of the high salt content of the forage reducing bot…
