Vinificazione in bianco in presenza di chips di quercia di origine e livello di tostatura diversi
2011
Some musts from Grillo grapes, a cultivar autochthonous of western Sicily, fermented with medium toasted American oak chips or with non toasted French oak chips (Classic Line – HTS enology) have been vinified. the wines were significantly different as regards the contents in volatile and non volatile compounds extracted from American and French oak chips. a slight increase in alcoholic fermentation rate and in some cases a higher content of ethyl esters and medium chain fatty acids, were observed in musts charged with chips, independently of their origin. In wines obtained from musts charged with french medium toasted oak chips, the content in furans was higher (5-methylfurfural, trans-meth…
Work commitment and engagement in south Italian volunteers
2009
Objectives. Recent research on volunteering has increased its interest in integrating different theoretical models such as motivational and socio-psychological ones. The current research replicates and extends a Swiss survey (Guntert, 2008) among a sample of Italian volunteers. The aim was to examine the antecedents (mainly in terms of motivational factors and identification) of outcomes such as commitment and engagement towards volunteering. Methods. To examine these antecedents and the outcomes, a questionnaire was administered to a sample of 165 young Italian adults who were engaged in various voluntary associations in south Italy (Campania and Sicilia). Results. Our analyses, underlinin…
Caracterización fisiológica, bioquímica y molecular de nuevas variedades de naranja de pulpa roja
2023
El objetivo principal de esta Tesis Doctoral ha sido caracterizar en profundidad los frutos de dos nuevas mutaciones de naranja dulce de pulpa roja, denominados Kirkwood Navel y Ruby Valencia, procedentes de las naranjas Washington Navel (cv. Palmer) y Valencia late (cv. Olinda), respectivamente. Para ello, se abordaron las bases fisiológicas y moleculares del metabolismo de carotenoides implicadas en la singular coloración del fruto, la evolución de los componentes de calidad de los frutos durante la maduración, su aptitud para la conservación postcosecha y comercialización en fresco, y el potencial de estas nuevas variedades para la producción y procesado de zumo. Los resultados bioquímic…
Chemical Composition of the Essential Oil of Bupleurum Fontanesii (Apiaceae) Growing Wild in Sicily and its Activity on Microorganisms Affecting Hist…
2016
Hydrodistillation of the flowers (BpFl) of and fruits (BpFr) of Bupleurum fontanesii Guss. ex Caruel gave two oils that were analyzed by GC and GC-MS. The main components were α-elemol (16.7%), caryophyllene oxide (16.4%) and heptacosane (15.9%) in BpFl, and spathulenol (16.8%), caryophylladienol I (13.2%) and α-elemol (12.8%) in BpFr. A good antimicrobial activity against several microorganisms, including Bacillus subtilis, Staphylococcus aureus, Fusarium oxysporum and Aspergillus niger, all infesting historical art craft, was also determined.
Les limites de la théorie du salaire d'efficience
1998
Efficiency wage theory, evolved by the "new keynesians", is part of a research programme concerned with explaining "involuntary" unemployment as part of the "general equilibrium". So, these works are a synthesis attempt of neo-classical and keynesian analyses in the employment area. Indeed, the authors place their analysis in a walrasian framework, but they integrate a keynesian concept to complete their models. In order to achieve their purpose, the efficiency wage theorists formulate two propositions on which their argument is based: 1° the relation supposed rising between the rate of wage and the productivity of wage earners, 2° the determination of the rate of wage outside the market. W…

Characterization and antimicrobial activity of the volatile components of the flowers of Magydaris tomentosa (Desf.) DC. collected in Sicily and Alge…
2014
The essential oils of the flowers of Magydaris tomentosa (Desf.) DC. (Apiaceae) collected in Sicily (MSi) and Algeria (MAl), respectively, were obtained by hydrodistillation, and their compositions were analysed. The analyses allowed the identification and quantification of 23 components in MSi and 60 compounds in MAl, respectively, showing a very different profile in the composition of the two populations. The main components of MSi were cembrene (28.2%), α-springene (17.5%) and β-springene (14.8%), also present in MAl but in lesser amount (0.4%, 1.8% and 0.9%, respectively), whereas the principal constituents of MAl were (E)-nerolidol (35.4%), α-costol (13.3%) and β-costol (6.8%). Both MS…
Monotherapy with indacaterol once daily reduces the rate of exacerbations in patients with moderate-to-severe COPD: Post-hoc pooled analysis of 6 mon…
2014
Summary Background In patients with COPD, exacerbations are associated with poor quality of life and may shorten survival. Prevention of exacerbations is, therefore, a key objective in COPD management. Indacaterol, a once-daily ultra-long-acting β 2 -agonist, has been shown to reduce exacerbations in various studies. This pooled analysis evaluated the effect of indacaterol on exacerbations versus placebo. Methods Six-month data were pooled from three randomized, double-blind, and placebo-controlled studies: indacaterol 300 μg versus placebo (1 year); indacaterol 150 μg and 300 μg versus placebo (6 months); and indacaterol 150 μg versus placebo (6 months). All treatments were administered on…
