Abstract

A palladium catalyst supported on silk fibroin (Pd/SF) has been tested in the Sonogashira coupling reactions of a wide range of aryl iodides and terminal alkynes. The best catalytic performance was obtained at 90 °C using only 0.25 mol % metal loading under copper‐free conditions, in the presence of a H2O/EtOH (3 : 2 v/v) solvent mixture and triethylamine as the base, affording the coupling products in good yields. The Pd/SF‐based protocol was then successfully extended to the synthesis of benzofurans through Sonogashira‐Cacchi type annulation of 2‐iodophenol with terminal alkynes. Preliminary investigations on the recyclability and the heterogeneous behaviour of the catalyst were performed: hot filtration test and leaching test evidenced the presence of a small amount of soluble active palladium species into the reaction mixture. Nevertheless, Pd/SF could be reused in recharging test and it can be recycled in four consecutive runs with no significant deactivation. [ABSTRACT FROM AUTHOR]

9. JAN PATOĈKA: DALLA FENOMENOLOGIA GENETICA ALLA NUOVA FENOMENOLOGIA.

Author

Rizzo, Giorgio

Subjects
PHENOMENOLOGY
Abstract

The aim of this paper is to demonstrate if Jan Patočka’s overcoming of Husserl’s transcendental reduction can lead halfway to the conceptual framework of Hermann Schmitz’s New Phenomenology. I will prove that notwithstanding Patočka’s introduction of the concept of apparaître en tal que tel, his use of pictorial images as well as the adoption of conceptual oppositions prevents his philosophy from being the missing link, without question, between classic phenomenology and the New Phenomenology.

Abstract

In the present contribution we propose the results of an integrated measurement campaign including ground penetrating radar and passive seismic data achieved in the church of Santa Maria delle Grazie at Campi Salentina, a town close to Lecce, in southern Italy. The passive seismic results corroborate the interpretation of the main (quite numerous at it will be shown) anomalies identified thanks to the GPR investigation., peer-reviewed

38. THING AND SPACE IN HUSSERL (AND HEIDEGGER).

Author

RIZZO, GIORGIO

Subjects
EXPERIENCE, TOPOLOGY
Abstract

The phenomenological reason shows how the space and the thing conceived by the scientific and natural thinking are a construction upon the unitary and meaningful world of everyday experience; therefore the aim of this essaylk is to analyse, from an Husserlian point of view, the most foundational layers of "space" and "thing" beginning from the most fundamental stratum, called by Husserl "phantom", the mere res extensa, and arriving at kinaesthetic fields in which the apprehensional character of the things depends from the interplay of sequences of K's (kinaesthetic circumstances) and i's (correlative images) which blend into a unitary and meaningful system of experience. In order to better understand Husserl's notions of thing and space, the last part of this essay is concerned about a different conception of the same concepts in Heidegger. Indirect confrontation with Heidegger, namely, allows to find some critical and weak points in Husserl's analysis of thing and space. [ABSTRACT FROM AUTHOR]

Abstract

To analyse the performance of iXip in the prediction of prostate cancer (PCa) and high-grade PCa. A consecutive series of men undergoing MRI/FUSION prostate biopsies were enrolled in one centre. Indications for prostate biopsy included abnormal prostate-specific antigen (PSA) levels (PSA > 4 ng/ml) and/or abnormal digital rectal examination (DRE) and/or abnormal MRI. All patients underwent the evaluation of serum PSA-IgM concentration and the iXip ratio was calculated. Accuracy iXip for the prediction of PCa was evaluated using multivariable binary regression analysis and receiver operator characteristics (ROC) curves. Overall 160 patients with a median age of 65 (62/73) years were enrolled. Overall, 42% patients were diagnosed with PCa and 75% of them had high-grade cancer (Epstein ≥ 3). Patients with PCa were older and presented higher PSA levels, higher PIRADS scores and lower prostate volumes (PVs). On ROC analysis iXip presented an area under the curve (AUC) of 0.57 in the prediction of PCa and of 0.54 for the prediction of high-grade PCa. In our experience, immune PSA complexes are not predictors of PCa. iXip analysis should not be included in the diagnostic pathway of patients at increased risk of PCa. [ABSTRACT FROM AUTHOR]

Abstract

Silk fibroin (SF) obtained from Bombyx mori cocoon is a very promising biopolymer. It can be processed from aqueous solutions to obtain many versatile scaffolds useful in optoelectronics, photonics, and biomedicine. Aqueous solutions are prepared by dissolving degummed fibroin with chaotropic agents and then purifying by dialysis. This work presents, for the first time, a solubilization protocol, involving CeCl3·7H2O as chaotropic salt in water and ethanol, that allows to regenerate SF under a fibrous form, unlike the standard Ajisawa's method, which uses CaCl2 and allows to obtain aqueous gels. All the experimental analyses performed (SEM, XPS, WAXS, ATR‐FTIR, NMR) suggest that the fiber recovered preserves most of the morphological and structural features of the pristine SF and is doped with Ce(III) ions, that interact mainly with the oxygen atoms of CO moieties and side‐chains of amino acids. Ce(III) doped SF could be the base for new luminescent materials. [ABSTRACT FROM AUTHOR]

Abstract

James Clerk Maxwell rivoluziona il modo in cui i fisici osservano il mondo. Lo scopo del saggio è quello di dimostrare che lo scienziato scozzese arriva alla formulazione delle sue famose quattro equazioni facendo a meno di analogie mutuate da modelli meccanici. Queste infatti si apprezzano soprattutto per il loro carattere di universalità, astrattezza, coerenza e completezza.

Abstract

International audience; The study of the neo-punic amphorae from archaeological excavations in Rome (Nuovo Mercato di Testaccio), Ostia(Terme del Nuotatore) and Arles (Arles-Rhône 3 wreck) allowed the possibility of analyzing a category of little known NorthAfrican amphorae which were in circulation during the 1st century AD. This has also presented the opportunity to illustrateand discuss the limits of the few typological references available for the classification of such amphorae - Mau XL,Vindonissa 592, Oberaden fig. 25, n. 4, Dressel 18 forms - and to attempt a new methodological approach to typology, inwhich traditional morphological study has been associated with the analysis of petrographic and technical features offabrics, to set up a new integrated classification as realistically as possible and directly referable to production centers,which, although not always precisely located, are likely to be found mainly in the Tunisian Sahel area.

49. Motivazioni e cause. Una lettura fenomenologica

Fenomenologia, sopravvenienza parziale, motivazioni, cause
Abstract

Se la nostra capacità di comprendere gli altri, oltre noi stessi, fosse fondata solo su un atteggiamento personalistico, allora non ci si sognerebbe mai di dire, se non in circostanze eccezionali, che, per esempio, “si è determinati (o, ancora peggio: causati) ad agire”; se, invece, si indulgesse verso un’attitudine o modo di vedere naturalistico, allora questo enunciato non suonerebbe “strano”. Nelle nozioni dunque di “motivazione”, “azione”, “causa”, oggetto d’analisi in questo saggio, albergano difficoltà teoretiche tanto più rilevanti quanto più si cerca di “far quadrare” ambiti d’indagine e regioni ontologiche differenti. Con quale prospettiva poi? Di armonizzarli mediante implausibili “riduzioni”? Appellan- dosi ai dispositivi tecnico-concettuali offertici dalle varie teorie della soprav- venienza oggi in voga? Di fissarli in inconciliabili opposti? Oppure, magari, di leggerli alla luce di una storia genetica che, al tempo stesso, li leghi (ontologica- mente) e li separi (epistemologicamente)? Il seguito di questo saggio cercherà di dare una risposta, anche se non risolutiva, alle domande di cui sopra, mantenen- dosi in una prospettiva che oggi si definirebbe “inflazionistica”, ovvero aperta al contributo che l’analisi di ogni livello di organizzazione del reale può apportare alla “comprensione” della complessità strutturale dello stesso .

Fenomenologia, Antiriduzionismo, Causalità, Motivazione
Abstract

A partire da "Ideen II", Husserl sembra mitigare quel forte dualismo metafisico che improntava il suo percorso filosofico iniziale. Così "causalità" non è più intesa come opposta a "motivazione" alla stessa stregua di come "interno" è opposto ad "esterno". Si fa strada invece l'idea che la prima nozione sia il risultato di un "raffinamento concettuale" della seconda. In questo senso, nel saggio è proposta una indagine genetica di quegli "Erlebnisse" in cui si costituisce la nozione originaria di motivazione.
