Classification of olive leaves and pulp extracts by comprehensive two-dimensional liquid chromatography of polyphenolic fingerprints.
2019
Abstract The development of a new comprehensive two-dimensional liquid chromatographic method is described, to obtain the profiles of polyphenolic compounds present in olive (Olea europaea L.) leaves and pulps from different genetic origin. Optimisation of the stationary phase nature, particle size, column length and internal diameter, as well as other separation conditions, was performed. Along the study, three stationary phases (C18, PFP and phenyl) in the first dimension (1D), and five (C18, amide, cyano, phenyl and PFP) in the second dimension (2D) were combined to obtain the maximal number of resolved peaks. The optimised method successfully characterised the presence of 26 and 29 comm…
Entonació i pressuposició en les interrogatives absolutes del mallorquí
2010
Aquest treball investiga de quina manera l’entonació reflecteix el diferents graus de coneixement del parlant en les interrogatives absolutes del mallorquí. Mitjançant tres experiments de percepció (un test d’adequació, un test d’avaluació i un test d’identificació basat en el paradigma clàssic de la percepció categorial) s’ha pogut demostrar que els oients catalans distingeixen quan el parlant no té ni idea de quina serà la resposta de la pregunta que està produint de quan el parlant té certes hipòtesis sobre quina hi serà la resposta i cerca confirmació d’aquestes hipòtesis. També s’ha pogut comprovar que les interrogatives manifesten una gradació de coneixement del parlant a l’hora de pr…
Política i grups de pressió
2021
La complexitat social i econòmica de les democràcies representatives contemporànies, caracteritzades per la pluralitat d’actors i estàndards axiològics, comporta el repte d’articular estratègies destinades a regular la conducta dels grups de pressió que, mitjançant la influència i l’acció de lobby, dirigeixen les seues legítimes aspiracions i interessos als decisors públics. La necessitat de concedir transparència i integritat a les relacions entaulades entre l’àmbit institucional públic i la societat civil, els sectors econòmics i empresarials, no sols implica una actualització normativa en la lluita contra la corrupció, sinó una complementària articulació jurídica destinada a fomentar bon…
Sakarība starp acs iekšējo spiedienu un redzes nerva diska parametriem
2017
Maģistra darbs uzrakstīts uz 43 lappusēm. Darbs satur 25 attēlus un atsauces uz 41 literatūras avotu. Darba mērķis bija novērtēt acs iekšējā spiediena saistību ar redzes nerva ekskavācijas eksentricitāti cilvēkiem, kuriem nav konstatēta glaukoma. Pētījumā tika veikts Itālijā un tika analizētas 100 cilvēku acis. Pētījuma dalībnieku vecums bija no 25 līdz 45 gadiem, no kuriem 41 bija sieviete un 59 vīrieši. Tika novērtēts acs iekšējais spiediens, ņemot vērā radzenes pahimetrijas datus un tika iegūtas ar fundus kameru redzes nervu fotogrāfijas. Darbā tiek secināts, ka veselām acīm nepastāv korelācija starp acs iekšējo spiedienu un ekskavācijas lielumu, kā arī nepastāv korelācija starp vecumu. …
Normal pressures and frictional tractions on shallow conical hopper walls after concentric filling: Predictions and experiments
2013
Author's version of an article in the journal: Chemical Engineering Science. Also available from the publisher at: http://dx.doi.org/10.1016/j.ces.2012.11.028 A silo with a shallow hopper is designed to achieve the required silo capacity when the headroom available is limited, provided that the issue of segregation of stored particulate solids is not a problem. Several analytical models have been proposed to try to predict the design loads for such shallow silo hoppers to guarantee their structural integrity. In this study, a novel finite element analysis has been conducted to explore the development of pressures and tractions on the wall of a full scale shallow hopper when it is filled wit…
Due democratiche cristiane alla Consulta nazionale: Laura Bianchini e Angela Maria Guidi Cingolani
2022
Questo articolo appartiene a uno studio più ampio che mira a ricostruire una tradizione politica femminile per comprendere alcune delle ragioni persistenti dietro il divario di genere tra accesso formale e sostanziale alle decisioni. L’obiettivo finale è quello di evidenziare il ruolo e il contributo delle donne, soprattutto di quelle che sono finite nell’oblio, nella costituzione di un’Italia democratica e repubblicana fin dalle loro prime partecipazioni all’Assemblea Nazionale Consultiva. L’Archivio della Camera dei Deputati, l’Archivio dell’Istituto Sturzo e gli articoli delle riviste dell’epoca sono state le fonti primarie della ricerca.Il 25 settembre 1945 si inaugura la Consulta che r…
The application of a reduced volume method for the simulation of the characterisation of a carbon fibre pressure vessel
2018
International audience; The characteristics of advanced composite materials make them ideally suited for use in pressure vessels for storing gas as fuel for ground transport vehicles. It has been found that the failure process starts with randomly distributed fibre breaks and as the loading continues, they coalesce into clusters of fibre breaks which lead to failure [4]. However, improvements are needed to reduce computational times when performing full-scale simulations. The reduced volume method is therefore applied to the stochastic fibre break model related to the concept of an integral range. This method allows the calculation for a certain volume of a laminate that statistically repre…
A comparison between the single ring pressure infiltrometer and simplified falling head techniques
2013
Testing the relative performances of the single ring pressure infiltrometer (PI) and simplified falling head (SFH) techniques to determine the field saturated soil hydraulic conductivity, Kfs, at the near point scale may help to better establish the usability of these techniques for interpreting and simulating hydrological processes. A sampling of 10 Sicilian sites showed that the measured Kfs was generally higher with the SFH technique than the PI one, with statistically significant differences by a factor varying from 3 to 192, depending on the site. A short experiment with the SFH technique yielded higher Kfs values because a longer experiment with the PI probably promoted short-term swe…
Combined use of modified atmosphere packaging and high pressure to extend the shelf-life of raw poultry sausage
2014
International audience; The contribution of modified atmosphere packaging (MAP) in extending the shelf-life of high-pressure treated raw poultry sausages was examined by considering microbial and oxidative stability (TBARs) aspects. Raw poultry sausages packaged under air or modified atmosphere (50% CO2–50% N2) were pressurized at 500 MPa during 5 min at a maximum temperature of 10.5 °C, subsequently allowed to refrigerated storage during 22 days. During storage, samples were tested at time intervals for headspace gas composition, pH, TBARs, Aerobic Mesophilic Counts (AMC) and Lactic Acid Bacteria (LAB) counts. The high pressure treatment could represent an efficient means of extending the …
Fatty Acids and Triacylglycerols Profiles from Sicilian (Cold Pressed vs. Soxhlet) Grape Seed Oils
2021
Among the Sicilian economic productive sectors, that of wine production has today a considerable economic value. However, with the growth of this sector, notable was the increase in the production of waste, which to date is not only an economic damage for companies, but also a threat to the environment. It is known that waste from wine production has properties (e.g., antioxidants) which have potential reuse at cosmetic, pharmaceutical and nutritional levels to obtain economically sustainable applications. A new goal is given by the recovery of added value compounds from agri-food wastes and by-products. Grape seed oil is a promising vegetable fat and cold pressing does not involve the use …
