Modelling of retention of pesticides in reversed-phase high-performance liquid chromatography: Quantitative structure-retention relationships based on solute quantum-chemical descriptors and experimental (solvatochromic and spin-probe) mobile phase descriptors
No full textA quantitative structure-retention relationship (QSRR) analysis based on multilinear regression (MLR) and artificial neural networks (ANNs) is carried out to model the combined effect of solute structure and eluent composition on the retention behaviour of pesticides in isocratic reversed-phase high-performance liquid chromatography (RP-HPLC). The octanol-water partition coefficient and four quantum chemical descriptors (the total dipole moment, the mean polarizability, the anisotropy of the polarizability and a descriptor of hydrogen-bonding based on the atomic charges on acidic and basic chemical functionalities) are considered as solute descriptors. In order to identify suitable mobile phase descriptors, encoding composition-dependent properties of both methanol- and acetonitrile-containing mobile phases, the Kamlet-Taft solvatochromic parameters (polarity-dipolarity, hydrogen-bond acidity and hydrogen-bond basicity, pi*, alpha and beta, respectively) and the N-14 hyperfine-splitting constant (a(N)) of a spin-probe dissolved in the eluent are examined. A satisfactory description of mobile phase properties influencing the solute retention is provided by a(N) and beta or alternatively pi* and beta. The two seven-parameter models resulting from combination of a(N) and beta, or pi* and beta, with the solute descriptors were tested on a set of 26 pesticides representative of 10 different chemical classes in a wide range of mobile phase composition (30-60% (v/v) water-methanol and 30-70% (v/v) water-acetonitrile). Within the explored experimental range, the acidity of the eluent, as quantified by alpha, is almost constant, and this parameter is in fact irrelevant. The results reveal that a(N) and pi*, that can be considered as interchangeable mobile phase descriptors, are the most influent variables in the respective models. The predictive ability of the proposed models, as tested on an external data set, is quite good (Q(2) close to 0.94) when a MLR approach is used, but the modelling capability can be further improved using an artificial neural network.

terminacijskog natpisa iz Bljušćevice kod sela Rastovca u
Trogirskoj zagori koji je u vrijeme Publija Kornelija Dolabele
uklesan u kamen živac. Također donosi novi nalaz cipusa iz zaselka
Bašelovici u Grebaštici kod Šibenika. Na njemu se spominje
Salto(ru)m F(inis) / Tariot(arum), a oznacava zapadnu granicu
tariotskog pašnjaka.The author provides a correction to the previous reading of the
Roman boundary inscription from Bljušćevica near the village of
Rastovac in the elevated hinterland of Trogir which was engraved
in solid rock during the consulship of Publius Cornelius Dolabella.
He also presents a new discovery of a cippus from the hamlet
of Bašelovici in Grebaštica near Šibenik. The inscription reads
Salto(ru)m F(inis) / Tariot(arum), designating the western boundary
of the Tariote pastures
Portrait de l’artiste en facteur de ponts
No full textLe texte “Portrait de l’artiste en facteur de ponts” relève davantage du témoignage personnage personnel que de l’article. L’auteur, le dramaturge Enzo Cormann, y donne des “Notes pensives en résonance de l’œuvre de Jean-Marie Piemme” : une série de notes, de forme libre, non ponctuées qui réagissent, commentent et dialoguent avec l’œuvre et avec les écrits critiques de Piemme.The text "Portrait de l'artiste en facteur de ponts" (Portrait of the artist as a bridge-builder) is more of a personal testimony than an article. In it, the author, playwright Enzo Cormann, gives some "Notes pensives en résonance de l'œuvre de Jean-Marie Piemme": a series of free-form, unpunctuated notes that react to, comment on and dialogue with Piemme's work and critical writings
Nuevas derechas, viejas izquierdas : Una conversación con Enzo Traverso
No full textThe present reflections are the result of a series of conversations with Enzo Traverso that took place in mid-November, in the city of Buenos Aires. Traverso obtained his PhD degree at the École des Hautes Études en Sciences Sociales (Paris, France), who currently works as a professor and researcher in the United States. Author of important books on contemporary European history, Enzo Traverso has written numerous reflections on historiographical practice and on the relationship between memory, politics and history. During his last visit to Argentina, he gave lectures and seminars in the framework of the Marx 200 years International Encounter. On this occasion, and about the publication in Spanish of his last two books (The New Faces of the Right and Left Melancholy. Marxism, history and memory), he agreed to discuss the new Latin American rights, the feminist movements, the situation of the left worldwide, and the nature of neoliberalism. Here we present and transcribe the result of those conversations.Las presentes reflexiones son el resultado de una serie de conversaciones con Enzo Traverso que tuvieron lugar a mediados de noviembre, en la ciudad de Buenos Aires.

En su última visita a la Argentina, dictó conferencias y seminarios en el marco del Encuentro Internacional Marx 200. En esta oportunidad, y a propósito de la publicación en español de sus dos últimos libros (Las nuevas caras de la derecha y Melancolía de izquierda. Marxismo, historia y memoria), aceptó debatir sobre las nuevas derechas latinoamericanas, los movimientos feministas, la situación de la izquierda a nivel mundial, y la naturaleza del neoliberalismo.

La domus sentinate col mosaico di Aiòn:decorazione musiva e anomalie iconografiche
No full textPrevious careful “excavation” work in the archives had allowed the author to shed light on the little known antiquarian issues relating to the discovery, removal and sale to Duke Ludwig of Bavaria of the great multi-coloured mosaic of Aion at the centre of the zodiac and Tellus with the four seasons. The work was discovered in the first half of the nineteenth century in a town house in Sentinum (modern day Sassoferrato, in the province of Ancona).
Now, some decades later, the author returns to the subject for a more detailed stylistic examination of the mosaic and of the mistakes and iconographic anomalies, especially in terms of the sequence of the signs of the zodiac, since the Sentinum mosaic only has eleven signs and these are not depicted in accurate astronomic order.
This contribution re-launches the thesis that such incongruities and anomalies should be attributed to damage done by the excavators and nineteenth century restorers in cutting and later putting the panels back together when the great mosaic was sectioned to make transport to Munich possible and that it is preferable to attribute such mistakes and lack of understanding to groups of itinerant Italian mosaic makers working from “travelling” drawings of complex subjects who did not fully understand the deep astronomical and symbolic meaning
POSITIVE EXISTENTIALISM OF ENZO PACI
No full textThe article deals with analysis of philosophic views of one representative of Italian existentialism - Enzo Pachi. It investigates principle ideas of his philosophy, his attempts to link irrational with rational in the problem of world structure. Using key sources of the essence of positive existentialism we can see how philosophy of Pachi is connected with Gusserl phenomenology, some ideas of Marx and other philosophers who thought about the human being. Positive existentialism of Pachi is considered to be non-system philosophy, which is open to different ideas and directed to uniting people through overcoming their problems. The author comes to the conclusion that philosophy of E.Pachi is an integral and important part of existentialism as a philosophic trend in general
