La medicina ellenistica in Plutarco
2004
Il saggio, attraverso l'analisi di svariati passi dei "Moralia" e delle "Vite" contenenti citazioni e rimandi espliciti ai più importanti esponenti della medicina ellenistica o semplici allusioni alle loro teorie, ricostruisce il debito di Plutarco nei confronti di quel sapere, mostrando come, insieme ai trattati ippocratici, anche gli scritti di Erofilo, Erasistrato, Asclepiade di Bitinia, Temisone di Laodicea, dovessero far parte della 'biblioteca' di Plutarco. L'esame delle testimonianze evidenzia altresì come, al pari del suo grande contemporaneo Galeno, anche Plutarco reinterpreta il patrimonio della medicina ippocratica ed ellenistica attraverso il filtro di un platonismo di fondo (Pl…
Kandydat PSL "Wyzwolenie" pierwszym prezydentem Polski, czyli wielka gra Stanisława Thugutta w grudniu 1922 roku
2019
In December 1922, the first presidential election in history took place in Poland. Voting was not universal because the National Assembly made their choice. One of the candidates for the office of president was proposed by Stanislaw Thugutt. He was the leader of the Polish People’s Party “Wyzwolenie/Liberation”. PPP “Wyzwolenie/Liberation” was one of the largest peasant parties in interwar Poland. In comparison with the largest peasant party in the Second Polish Republic – the Polish People’s Party “Piast” was a leftist party. On December 9, 1922, both parties supported the same candidate in a decisive vote. It was Gabriel Narutowicz, who was then the Minister of Foreign Affairs. In additio…
Hyperbranched polyethylenimines as versatile precursors for the preparation of different type of unimolecular micelles
2007
Abstract Hyperbranched polyethylenimine (HPEI) was successfully employed as precursor for the preparation of unimolecular inverted and aqueous micelles. The unimolecular inverted micelles (UIMs) obtained by the amidation of HPEI with 1,1′-carbonyldiimidazole (CDI) activated palmitic acid exhibited high encapsulation efficiency for hydrophilic anionic dyes and the efficiency could be enhanced significantly by decreasing the degree of amidation or quaternizing the residual amines. The weight ratio of loaded guests to the amidated HPEIs was not dependent on the molecular weight of HPEI core when the degree of amidation was kept constant. Decreasing the length of the aliphatic chain from 16 to …
Core–shell-type multiarm star polyethylenimine-block-poly(ɛ-caprolactone): Synthesis and guest encapsulation potential
2006
Novel multiarm star copolymers with poly(e-caprolactone) (PCL) as the arms and hyperbranched polyethylenimine (HPEI) as the core have been successfully prepared by the tin(II) 2-ethylhexanoate catalyzed ring-opening polymerization of e-caprolactone (CL) with HPEI used directly as a macroinitiator. Not only primary but also secondary amine groups of HPEI participate in initiating the ring-opening polymerization of CL with almost 100% initiation efficiency. The average degree of polymerization of the PCL arms can be controlled by the feed ratio of the monomers to the initiating sites. Because of the polarity difference of the PCL arms and HPEI core, the obtained multiarm star polymers display…
Molecular stabilization of chemically exfoliated bare MnPS3 layers
2021
Transition metal chalcogenophosphates of general formula MPX3 have attracted recent interest in the field of 2D materials due to the possibility of tuning their properties when reaching the 2D limit. Several works address this challenge by dry mechanical exfoliation. However, only a few of them use a scalable approach. In this work, we apply a general chemical protocol to exfoliate MnPS3. The method uses in a first step chemical intercalation and liquid phase exfoliation, followed in a second step by the addition of molecules used as capping agents on the inorganic layers. Therefore, molecules of different nature prompts the quality of the exfoliated material and its stabilization in aqueou…

THE PLEISTOCENE–HOLOCENE TRANSITION IN THE IBERIAN PENINSULA: CONTINUITY AND CHANGE IN HUMAN ADAPTATIONS
1998
Abstract Data obtained from recent excavations (as well as from selected older excavations) are used to outline the principal environmental, technological and economic aspects of the Pleistocene–Holocene transition in three distinct regions of the Iberian Peninsula: Portugal, Cantabrian and Mediterranean Spain. The period covered extends from the terminal Paleolithic Magdalenian period to the initial Neolithic. Despite proximity to SW France and many similarities with that classic prehistoric culture area in terms of artistic/symbolic expression and technology, the Iberian regions show significant differences, especially in terms of subsistence strategies and their development during the Ta…
Tommaso Stanislao Velasti tra filellenismo partenopeo e ideologia “albanista”
2021
L'opera del gesuita greco originario di Scio, Tommaso Stanislao Velasti, costituisce un compendio dell'ideologia filoellenica che a partire dalla seconda metà del XVIII secolo, influenzò i processi irredentistici che nel 1821 portarono la Grecia a proclamare la propria indipendenza dalla Sublime Porta. Nel suo percorso di ricerca, Velasti ebbe la fortuna di incontrare le opere di intellettuali albanesi di Sicilia, presso il cui seminario palermitano ebbe modo di dimorare negli anni cruciali della sua svolta ideologica. Lo studio di alcuni fondamentali documenti emersi dall'archivio del Seminario fondato da p. Giorgio Guzzetta ha evidenziato la filiazione di idee fondamentali dell'ideologia …
