Transesterification of rapeseed oil over acid resins promoted by supercritical carbon dioxide

2011

The methanolysis of rapeseed oil catalyzed by commercial styrene-divinylbenzene macroporous acid resins was performed in a batch reactor at 100-140 °C and 10-46 MPa to study the effect of supercritical carbon dioxide (scCO2) on the performances of the process. Reaction temperatures of 120-140 °C were necessary to obtain high enough yields of fatty acid methyl esters. Upon addition of scCO2 faster transesterification kinetics was obtained also at the lowest investigated operating pressure (10-11 MPa), working in two fluid phase systems. Experiments performed changing the reaction time indicated that most of the esters were formed during the first 3 h. When the pressure was increased at 38-46…

Genesis and destiny : for a dynamogenic’s conception of the myths

2012

If the myth has become today an unavoidable fact to understand the human soul and its different forms of expression, it remains, however, ambiguous and hardly conceptualizing. Indeed, the myth is at once understood as a fictitious narrative which isn’t based on any in-depth reality, but also as a real and highly significant discourse. In order to underline the philosophical meaning of our work, we have begun by assert the myth problem such as it evolves in the European thought. The myth is badly affected by a too long history; it has been divided between rationalism and romanticism. Then, we have questioned other civilizations – Fon from Dahomey, Benin – for whose myth represents all the hu…

Se a grandi ingiustizie corrispondono grandi punizioni. Alcune riflessioni sul lessico della sanzione divina in Erodoto

2016

In uno dei passi più rilevanti dell’opera Serse annuncia ai notabili persiani di voler conquistare la Grecia. L’attacco, secondo il ‘νόμος espansionistico’ inaugurato dai suoi predecessori, porterà non solo gloria all’impero persiano ma permetterà inoltre di conquistare una terra fertile e di ottenere finalmente “ἅμα τιμωρίην τε καὶ τίσιν”. Gli Ateniesi, che per primi hanno intrapreso azioni ingiuste contro la Persia, pagheranno per ciò che hanno fatto. Come rendere l’ideale retributivo espresso da questi due vocaboli utilizzati insieme? Esiste per lo storico di Alicarnasso una chiara distinzione tra un atto punitivo e uno meramente ritorsivo? Lo studio delle forme di causalità presenti nel…

“She Shuddered on her Throne and Made high Olympus Quake.” Causes, Effects and Meanings of the Divine Nemesis in Homer

2015

This article aims at exploring the Homeric gods’ sensitivity to a particular kind of indig- nation that is expressed in the Homeric po- ems by the term nemesis and by the verbal forms arising from it. My purpose is to an- alyse the passages that allow us to establish the causes of divine nemesis towards the mortals and the gods themselves, as well as their effects. This survey also represents an opportunity for investigating the relation between the attribution of emotions to the Greek gods and the anthropomorphic repre- sentation of the divine.

IS HYPOXIA-INDUCIBLE FACTOR (HIF-1) ALPHA INVOLVED IN TARAVANA SYNDROME?

2021

Breath holding diving (BH) is a discipline practiced by an increasing number of people. BH-divers are exposed to extreme environmental conditions such as: increased hyperbaric pressure and low temperature that caused change in arterial blood gases (1-2) and induced an human diving response which includes bradycardia, reduced cardiac output, increased arterial blood pressure and peripheral vasoconstriction (3). Some of these adaptations are still not fully understood, so we decided to investigate some biomarkers that should be involved in this disorders starting to analyse Hypoxia-inducible factor 1 alpha (HIF-1α). We enrolled in our study 31 healthy free divers from different part of Sicily…

Diels-Alder Reactions ofin situ generated N-benzoylindolo-2,3-quinodimethane with carbodienophiles

1993

The indolo-2,3-quinodimethane (5), generated from 2,3-bis(bromomethyl)indole (4), was trapped with unsymmetrical carbodienophiles or N, N′-p-phenylenedimaleimide to furnish the 1,2,3,4-tetrahydrocarbazoles (6–9). [4 + 2]-Cycloaddition of 5 with tetracyanoethylene gave rise to the tetracyanocarbazole (10) and a subsequent product 11a or 11b. The Diels-Alder reaction of 5 with divinyl sulfone was regiospecific within the detection limits of HPLC analysis. Similarly, the reaction of 5 with N, N′-p-phenylenedimaleimide yielded solely the stereoisomer 9.

Determination of phenolic antioxidants additives in industrial wastewater from polypropylene production using solid phase extraction with high-perfor…

2019

Abstract This paper describes a new method for the effective extraction of the residues of five synthetic phenolic antioxidants (AOs): Ditertbutylphenol (DTF), Irganox 1010, Irganox 1076, Ethanox 330 and Cyanox 1790, from industrial water produced during the polypropylene (PP) deodorization process. In the deordorization process, PP is stored in a column for an average time of four hours and exposed to nitrogen and water vapor to remove inflammable compounds which may generate atypical odors in the PP. The samples of interest were taken in the desorber, followed by cleansing and pre-concentration using modified styrene divinylbenzene polymer cartridges. Liquid chromatography was performed w…

Two-Leg Squat Jumps in Water: An Effective Alternative to Dry Land Jumps

2009

The current study was designed to quantify and compare the kinetic parameters of two-leg squat jumps carried out on dry land, in water and in water using area devices that increase drag force. Twelve junior female handball players who had been competing at national level for the previous two years volunteered to participate in the study. Intensity of the two-leg squat jump was examined using a force plate (9 253-B11, Kistler Instrument AG, Winterthur, Switzerland) in three different conditions: on dry land, in water and in water using devices. An ANOVA with repeated measurements (condition) was applied to establish differences between the three jumps. The results show that peak impact force…

MADNESS AND BESTIALIZATION IN EURIPIDES'HERACLES

2013

Against a background of anxious evocation of Dionysiac rites, Euripides'Heraclesstages the extreme degradation of the tragic hero who, as a consequence of the hatred of a divinity, loses his heroic traits and above all his human ones in the exercise of brutal violence. By comparing Heracles in the grip of madness to a furious bull assailing its prey, the tragedian clearly shows the inexorability of the divine will and its arbitrariness, and emphasizes madness itself through images traditionally associated with the bull. However, the reference to monstrosity and animals does not only involve Heracles, but also concerns the representation of Lyssa, the demon of madness sent by Hera to induce …
