Cesarea di Mauretania: la piccola Grecia di Giuba II, tra bronzi e marmi
2020
Punic Iol, renamed Caesarea in honour of Augustus under Juba II, and promoted by the latter to the rank of capital of the kingdom of Mauretania entrusted to him by the princeps in 25 B.C., underwent a splendid phase of development on the model of Hellenistic cities precisely between the end of the 1st century B.C. and the first part of the 1st century A.D. It is very probable that Juba II, who had grown up in Rome, had provided Caesarea with a port, as the intense trade with the Iberian Peninsula, Gaul and Italy, from whose marble quarries material was extracted for architectural constructions and decorations, as well as from those in Greece, would prove. Caesarea has returned a complex of …
La vocazione centripeta. Una divergenza ideologica tra Libanio e Temistio di fronte alla prospettiva costantinopolitana dei buleuti di Antiochia
2016
Questa ricerca è incentrata su due personaggi, Temistio e Libanio, che sono esempio di intellettuali orientati verso una prospettiva volta a cogliere i profili di interazione sociale che la loro attività letteraria seppe contemplare. Se i due sono assimilabili per formazione culturale e professione, restano tuttavia ben distinti l’uno dall’altro per tutte le altre rispettive scelte di vita: dal 354 d.C. Libanio si stabilisce definitivamente ad Antiochia, un anno prima di quello in cui Temistio viene nominato senatore di Costantinopoli, inaugurando di seguito la sua carriera di intellettuale organico. L’opera di Temistio e quella di Libanio sono, in realtà, due manifestazioni tra loro antipo…
Undecylenic acid: A tunable bio-based synthon for materials applications
2016
International audience; An undecylenic acid-based monoglyceride prepared from glycidol and undecylenic acid is used as suitable and tunable synthon for polymerization applications. Epoxidation and acrylation reactions lead to photopolymerizable monomers while transesterification with dimethyl carbonate, metathesis and aminolysis reactions provide access to polyhydroxyurethane-based materials. The successive intermediates were synthesized according to a green chemistry approach implicating solvent-less and catalyzed reactions, and were at each step fully characterized by infrared, 1H and 13C{1H} NMR spectroscopy, elemental analysis and mass spectrometry. Analyses of the resulting polymer mat…
SEM–EDS ANALYSIS AS A RAPID TOOL FOR DISTINGUISHING CAMPANIAN A WARE AND SICILIAN IMITATIONS
2013
The aim of this work is to examine whether it is possible to find chemical markers that allow a distinction to be made between the imported black glossed ‘Campanian A’ and the Sicilian imitation (end of fourth to first century BC) of these productions by carrying out quantitative chemical microanalysis of the slip using the SEM–EDS technique. The efficiency of the proposed analytical method has been tested on a set of ceramic samples corresponding to Sicilian black gloss imitations whose ceramic body has already been characterized petrographically by thin-section microscopy and chemically by XRF. The analytical data point to Na2O as a suitable chemical marker to distinguish between original…
The Se … Hal halogen bonding: Co-crystals of selenoureas with fluorinated organohalides
2021
Abstract Synthesis and structural characterization of binary co-crystals 1–4 is reported in the present paper. Selenourea and 1,1-dimethylselenourea were used as selenium-containing halogen bond (XB) acceptors and iodopentafluorobenzene (IPFB), 1,4-diiodotetrafluorobenzene (1,4-DIFB) and 1,4-dibromotetrafluorobenzene (1,4-DBrFB) as XB donors. A comparative analysis of the similar binary co-crystals of selenourea and thiourea with a halogen donor revealed that Se … Hal halogen bonds are up to 13.12% shorter than the sum of vdW radii, while in case of S … Hal halogen bonds this value is 11.4%. Therefore, selenium tends to form stronger bonds with halogens than sulfur does. Comparisons of XB i…
LA OCUPACIÓN SOLUTRENSE DEL ABRIGO DE LA BOJA (MULA, MURCIA, ESPAÑA)
2013
El relleno pleistoceno del Abrigo de la Boja (ADB) empieza con un nivel adscrito al Magdaleniense superior, seguido de un potente paquete con ocupación difusa bajo el cual se desarrolla una secuencia depositada durante el último máximo glacial caracterizada por una serie de estructuras de combustión, de tipo hogar plano/amorfo (open hearth), existiendo también hogares de cubeta. Destaca un hogar enlosado, completo y muy bien conservado, excavado en 2012 y adscrito provisionalmente al Solutreogravetiense. Los niveles solutrenses subyacentes son ricos en elementos de adorno, entre los cuales conchas perforadas de Littorina obtusata y Smaragdia viridis; su industria lítica incluye raspadores, …
Modernity in Antiquity : Hellenistic and Roman Philosophy in Heidegger and Arendt
2020
This article looks at the role of Hellenistic thought in the historical narratives of Martin Heidegger and Hannah Arendt. To a certain extent, both see—with G. W. F. Hegel, J. G. Droysen, and Eduard Zeller—Hellenistic and Roman philosophy as a “modernity in antiquity,” but with important differences. Heidegger is generally dismissive of Hellenistic thought and comes to see it as a decisive historical turning point at which a protomodern element of subjective willing and domination is injected into the classical heritage of Plato and Aristotle. Arendt, likewise, credits Stoic philosophy with the discovery of the will as an active faculty constituting a realm of subjective freedom and autonom…
Preliminary results of systematic sampling of gas manifestations in geodynamically active areas of Greece
2016
Greece is located on a convergent plate boundary comprising the subduction of the African Plate beneath the Eurasian, while the Arabian plate approaches the Eurasian in a northwestward motion. It is considered to be one of the most tectonically active regions of Earth with a complex geodynamic setting, deriving from a long and complicated geological history. Due to this specific geological background, conditions for the formation of many thermal springs are favoured. In the past years, almost all the already known sites of degassing (fumaroles, soil gases, mofettes, gas bubbling in cold and thermal waters) located in the Hellenic area were sampled at least one time. Collected samples were a…
Le colpe della cultura pagana: riflessioni sull'Epistola 69b di Giuliano
2002
The article is a reflection starting from the epistle 89b of the emperor Julian, which is presented as an illuminating document for the reconstruction of the values of the Hellenic civilisation, based on a precise paideutic-religious programme, which takes the form of a kind of canon of praiseworthy and/or inadvisable authors
