Mechanisms of interference of p-diphenols with the Trinder reaction
2020
p-Diphenols, such as homogentisic acid, gentisic acid, etamsylate, and calcium dobesilate, interfere with diagnostic tests utilizing the Trinder reaction but the mechanisms of these effects are not fully understood. We observed substantial differences both in oxidation of p-diphenols by horseradish peroxidase and their influence on oxidation of 4-aminoantipyrine and various phenolic substrates. Homogentisic acid was rapidly oxidized by the enzyme and completely blocked chromophore formation. Enzymatic oxidation of the remaining p-diphenols was slow and they only moderately inhibited chromophore formation. However, in the presence of standard substrates all tested p-diphenols were rapidly co…
Assessment wine aroma persistence by using an in vivo PTR-ToF-MS approach and its relationship with salivary parameters
2019
To better understand wine aroma persistence, the nasal cavity of nine volunteers was monitored by Proton Transfer Reaction-Time of Flight-Mass Spectrometry (PTR-ToF-MS) after they rinsed their mouths with three rosé wines (one control and the same wine supplemented with two tannin extracts) during four minutes. Wines were aromatised with a mixture of five target aroma compounds. Results showed that wine aroma persistence was highly compound-dependent: while esters disappeared very fast, other compounds such as linalool remained in the oral cavity for longer times after wine expectoration. A low effect of tannins (at 50 mg/L) on nasal cavity parameters was observed, with the exception for th…
Masu apkalpošanas sistēmu tīklu optimizācija piegādes ķēžu plānošanā
2020
Šajā darbā masu apkalpošanas sistēmu tīkls tiek izmantots kā matemātiskais modelis piegādes ķēdes darbības analīzei. Tiek apskatīts veids kā izmantot masu apkalpošanas sistēmu tīklu gadījumā, kad tīklā ienākošo pieprasījumu plūsmu raksturo divi nepārtraukti gadījuma lielumi. Labākam kontekstam tiek aprakstīti masu apkalpošanas sistēmu un piegādes ķēžu teorētiskie pamati, kā arī raksturoti vaļēji un slēgti masu apkalpošanas sistēmu tīkli. Risinot teorētiskas piegādes ķēdes piemēru ar fiksētiem vidējiem apkalpošanas laikiem un maršrutēšanas varbūtībām, tiek meklēts piegādes ķēdes īsākais ceļš, jeb ceļš, pa kuru virzoties pieprasījumiem, vidējais laiks, ko pieprasījums pavada sistēmā ir vismaz…

The research is focused on almond paste production and aims at developing a new production process to deliver the high nutitional content of the raw almonds into finished product
MASCHILITÀ OMOSESSUALI TRA SESSO E AMICIZIA. COME LE ‘DATING APPS’ RISCRIVONO I COPIONI SESSUALI NEL XXI SECOLO
2021
This paper analysis sexual scripts theory in relation to gay men courtship, love relationships, and casual sex. The aim is to understand how gay masculinity is evolving in the 21st Century. Previous research has reinforced the concept that gay men follow heterosexual masculinity and scripts in their relationships with other men. Here, analysing data from the most used gay dating app ‘Grindr’, we try to understand the balance among the different needs gay men in Italy express in their daily lives: from friendship to love, from casual sex to long-term relationships. Indeed, applying the heterosexual cultural script to gay men is problematic because hegemonic masculinity is also reinforced in …
Croissance et convergence des pays de la zone CFA : une étude par les données de panel non stationnaires
2011
During the recent years, african countries in the CFA zone have experienced many economic changes on the one hand through the measures initiated by bilateral and multilateral donors and on the other hand through the economic and monetary integration policies. Thus, relying on the assumption that because of these interventions, the economic systems incorporate various phenomena such as structural change and economic interdependencies, we studied their major implications on growth, convergence and growth predictability. Emphasis is first placed on the major features of integration policies in a monetary union, while stressing the possible implications of such policies on the economic dynamics…
“Allochronic Views of Native Americans; or, Vanished Vanishing Indians in The Last of the Mohicans”
2016
James Fenimore Cooper’s The Last of the Mohicans; A Narrative of 1757, first published in 1826, offers an archetypal example, perhaps the archetypal example, of a literary expression of the trope of the Vanishing Indian. This theme is present in many works of nineteenth-century American literature that include Native Americans as their subjects, but Cooper’s romance, whose very title evokes the disappearance of an entire tribe, takes the sad fate of North America’s indigenous peoples as one o...
Chromatography with dense gases
1992
A capillary restrictor for supercritical fluid chromatography (SFC) with CO2 was made by using a micro torch and fine emery cloths or grinding blocks. This restrictor could be drawn out either directly from the end of the analytical capillary column, or from a short piece of any capillary, which was then connected to the analytical column by standard techniques. It was found that the base current of a flame ionisation detector (FID) depends strongly on the position of the capillary end with respect to the FID flame tip and on the CO2 grade, of course. Best results have been achieved at around 5 to 7 mm distance between the restrictor and the flame tip ends, and using SFC grade CO2.
Recyclable and Light-Adaptive Vitrimer-Based Nacre-Mimetic Nanocomposites.
2021
Nacre's natural design consists of a perfect hierarchical assembly that resembles a brick-and-mortar structure with synergistic stiffness and toughness. The field of bioinspired materials often provides attractive architecture and engineering pathways which allow to explore outstanding property areas. However, the study of nacre-mimetic materials should not be limited to the design of its architecture but ought to include the understanding, operation, and improvement of internal interactions between their components. Here, we introduce a vitrimer prepolymer system that, once integrated into the nacre-mimetic nanocomposites, cures and cross-links with the presence of Lewis acid catalyst and …
