Advanced Formation Fluid Evaluation While Drilling with a New Heavy Gas Detector

2012

In this paper, a chromatograph which exploits the benefits of FID technology optimized for the high resolution detection of heavier hydrocarbon gas components is described. The components analyzed span from n-hexane to toluene. Flame Ionization Detector (FID) technology is not new to gas detection on the field, however it had never been applied to the detection of gases heavier than n-pentane. The instrumentation has been installed and run on a number of wells in different fields and countries, and it has operated as a complement of an advanced surface logging system for a period of two years. Unlike other technologies presently utilized for this scope, this system reduces dedicated equipme…

I diritti dei lavoratori nella globalizzazione. Che prezzo (se lo conosciamo) siamo disposti a pagare?

2015

L’articolo ha come obiettivo dimostrare l’inefficacia del diritto del lavoro in tempi di globalizzazione nel tutelare il lavoratore, quale contraente debole del rapporto di lavoro. Dopo una breve disamina del contesto storico-politico della globalizzazione, che ha portato ad un diritto del lavoro sempre più privatizzato, si insiste nell’assenza di una forma di protezione universale per i lavoratori dal punto di vista del diritto internazionale pubblico nei sistemi OIL-WTO-carte Onu; si individua infine come unica tutela transnazionale, e comunque orientata in senso favorevole al mercato, la giurisprudenza della Corte di Giustizia alla luce delle disposizioni della Carta europea dei diritti …

Lavoro e sicurezza sociale dei migranti economici: l'eguaglianza imperfetta

2021

Il saggio analizza i diritti dei migranti economici in Italia alla luce dei principi di eguaglianza e non discriminazione in chiave multilivello, in relazione ad accesso al lavoro, esecuzione del contratto e prestazioni di sicurezza sociale. Nella prospettiva dei diritti fondamentali del lavoratore il quadro normativo non è per nulla confortante: è estremamente difficile un ingresso regolare dei migranti sul territorio nazionale in virtù della legislazione di riferimento. Inoltre, sul versante dell’assistenza sociale il principio paritario soffre numerose eccezioni che di recente sono state avallate da un revirement del Giudice delle leggi nella sentenza 50/2019 in materia di assegno social…

What olive oil for healthy ageing

2015

The olive tree originated in Asia Minor around 6000 years ago and then spread to all the Mediterranean basin. Olive oil is extracted from the pulp of its fruits [1–3]. Many studies show that the nutritional pattern of the so-called Mediterranean Diet is associated with a lower incidence of age-related diseases related to inflammation and oxidative stress, such as cardiovascular disease, Parkinson's disease, Alzheimer's disease and cancer [4–7]. It is now clear that olive oil, as a main source of fat, must play a key role in explaining the health benefits of the Mediterranean Diet.

Chemical Composition and Antibacterial Potential of Artemisia arborescens L. Essential Oil

2011

This study was undertaken to characterize the essential oil (EO) of Artemisia arborescens growing wild in Sicily. EO, extracted by steam distillation, was examined for its chemical composition and for its capability to inhibit some food-borne pathogen bacteria. A total of 43 compounds (13 monoterpene hydrocarbons, 14 oxygenated monoterpenes, 10 sesquiterpene hydrocarbons, three oxygenated sesquiterpenes and less amount of other three compounds), which account 93.73% of the total oil, were identified by gas chromatography and gas chromatography-mass spectrometry. Oxygenated monoterpenes (57.32%) constituted the main fraction, with β-thujone as the main compound (45.04%), followed by the sesq…

OLIVE OIL CONSUMPTION AND RISK OF CORONARY HEART DISEASE AND/OR STROKE: A META-ANALYSIS OF CASE-CONTROL, COHORT AND INTERVENTION STUDIES

2014

Increasing evidence suggests that the Mediterranean diet can reduce the risk of CVD. Olive oil is the hallmark of this dietary pattern. We conducted a meta-analysis of case–control, prospective cohort studies and a randomised controlled trial investigating the specific association between olive oil consumption and the risk of CHD (101 460 participants) or stroke (38 673 participants). The results of all observational studies were adjusted for total energy intake. The random-effects model assessing CHD as an outcome showed a relative risk (RR) of 0·73 (95% CI 0·44, 1·21) in case–control studies and 0·96 (95% CI 0·78, 1·18) in cohort studies for a 25 g increase in olive oil consumption. In co…

Perceived and measurable performance of daily brushing and rinsing with essential oils mouthrinse

2010

Aims. To determine whether the oral health benefits of recommending twice daily brushing and rinsing with an essential oil mouthrinse (EOM) are perceived and measurable by dentists and also perceived by their patients at a 3-month recall visit. Methods. This is a monadic, open label, uncontrolled study involving 766 generally healthy Italian subjects aged 19-66 years, with mild to moderate levels of gingivitis, no pockets of more than 4 mm, and at least 20 scorable teeth. Eight dentists scored subjects for plaque and gingivitis at baseline and at 90 days using simplified 4-point plaque and gingivitis indices. All subjects brushed twice daily, immediately followed by rinsing for 30 sec with …

The effects of two essential oil mouthrinses on supragingival plaque regrowth: a comparative study

2012

Aim: The aim of the study was to investigate the plaque inhibiting effects of two commercially available mouthrinses containing essential oils (EO): Listerine (Johnson & Johnson Consumer Healthcare, S. Palomba-Pomezia, I) and Curasept Daycare (Curaden Healthcare, Saronno, I). Both products contain the same concentration of EO, but Curasept Daycare does not contain ethanol as a solvent. Material and Methods: The study was a single-center, observermasked, cross-over design with 12 subjects randomly allocated to treatment sequence according to three replicates of a 4x4 Latin square, incorporating balance for any carryover. A 0.12% chlorhexidine (CHX) rinse and a saline solution served as posit…
