Song (960-1279) caramics: aesthetics, theories, and archaeological discoveries
No full textSong ceramics have been highly appreciated in the West since they were first imported at the end of the 19th century and in China since at least the 13th century. The concept of “five famous wares of the Song dynasty”, namely Ding, Ru, Jun, Guan and Ge, has informed the discourse on Song ceramics as if it had been transmitted from a remote past, thus influencing our perception. But was it really?
Archaeological excavations carried out in the past 15 years have undermined the reliability of the theory of the “five famous wares” prompting a thorough re-examination of ancient Chinese written sources which has proved that, in fact, it is a 20th century notion that surreptitiously emerged in the 1950s and slowly, but inexorably asserted itself until it became unshakable in the 1980s. It does not reflect the perception of Song ceramics by Ming connoisseurs and even less the perception of Song wares by their contemporaries
The paper concludes with a long comment on the aesthetics of Song ceramics which re-considers what was favoured by the court (in Kaifeng and Hangzhou) and the main genres produced at the time. The outcome is a more balanced judgement that lays the groundwork for future research into the appreciation of ceramics in Song times
Un'annotazione orientata alla ricerca acquisizionale
No full textIn questo lavoro gli autori sottolineano i limiti dell'etichettatura degli errori degli apprendenti e propongono una forma di annotazione di categorie morfosintattiche che rispetta la potenziale conflittualità tra valori formali e valori funzionali presenti nelle forme delle primissime interlingue

Sensory and instrumental assessment of olive oil appearance
No full textThis work aimed to establish parameters concerning colour and turbidity of extra virgin olive oils by comparing consumers' visual perceptions with analytical measurements using a tristimulus colorimeter and a turbidimeter.
The Principal Component Analysis (PCA) was applied to explain the differences between the various oils in terms of analytical parameters (L, a, b and NTU) and sensory attributes (Yellowness, Greeness and Turbidity). The results showed that the instrumental and sensory parameters are strongly correlated
Corpora di italiano L2: tecnologie, metodi, spunti teorici
No full textI corpora di apprendimento - raccolte di testi scritti e orali prodotti da chi impara una lingua - sono fonti preziose per la conoscenza del fenomeno dell'apprendimento. La progettazione e l'analisi di corpora di questo tipo è una frontiera promettente sia per gli studi acquisizionali sia per gli studi computazional
"All on short" prosthetic-implant supported rehabilitations
No full textObjectives. Short implants are increasing their popularity among clinicians who want to fulfill the constant demanding of fixed prosthetic solutions in edentulous jaws. The aim of this report was to propose a new possibility to project and realize an occlusal guided implant cross-arch prosthesis supported by ultra-short implants, describing it presented an edentulous mandible case report. Methods. A 61-year-old, Caucasian, female patient who attended the dental clinic of the University of L’Aquila presented with edentulous posterior inferior jaw and periodontitis and periimplantitis processes in the anterior mandible. The remaining tooth and the affected implant were removed. Six 4-mm-long implants were placed to support a cross-arch metal-resin prosthesis. Results. At 1-year follow-up clinical and radiological assessment showed a good osseointegration of the fixtures and the patient was satisfied with the prosthesis solution. Conclusion. The method, even if it requires further validation, seems to be a valid aid in solving lower edentulous clinical cases, and appears less complex and with more indications of other proposals presented in the current clinical literature. Our case report differs from the current technique All-on-Four, which uses four implants in the mandible to support overdenture prosthesis, assuring a very promising clinical resul
Ultrashort Implants, Alternative Prosthetic Rehabilitation in Mandibular Atrophies in Fragile Subjects: A Retrospective Study
No full textThis study aimed to evaluate the effectiveness of using ultrashort implants in the rehabilitation of jaws of fragile patients. The aim of the study was to retrospectively evaluate the survival rate of full-arch prosthetic rehabilitation on ultrashort implants, length 4 mm, 4 mm in diameter in the premolar and canine area and 4.5 mm in diameter in the molar area, with the insertion torque of 60 Nw and immediate loading. Nineteen patients were evaluated for 3 years clinically and radiographically. The significant majority of the patients at the 3 year follow-up (T4) presented a stable and functional implant-supported prothesis, and the survival rate of the implants was 85%, with a loss of 16 implants on 114 implants. The combination of the innovative implant surfaces and the correct project of the prostheses, with the related implant connection, determined a different timing in the therapy, allowing to obtain an immediate loading, which is currently demanded by patients. This and recent reports on short and ultrashort implant usage in atrophic jaws offer a good solution in critical cases. In conclusion, within the limits of the study, the full-arch rehabilitation with immediate loading on ultrashort implants showed good results with few postoperative complications and related low biological cost
Una nuova interpretazione delle ceramiche Jun alla luce delle ultime scoperte archeologiche
No full textLe ceramiche Jun sono al centro di un acceso dibattito da quando gli scavi effettuati nel 2001 e nel 2004 hanno dimostrato che la tipologia cosiddetta “Jun numerato” o “Jun imperiale” non era fabbricata durante la dinastia Song Settentrionale (960-1127), bensì dalla fine del regime mongolo (1234-1368), vale a dire, almeno due secoli più tardi. Non tutti gli studiosi sono, comunque, d’accordo e il dibattito non è destinato a sopirsi in tempi brevi.
Questo contributo offre una nuova interpretazione delle ceramiche Jun sulla base delle scoperte archeologiche condotte dagli anni ’50 del secolo scorso e delle fonti letterarie antiche a partire dal XV secolo, quando, per la prima volta, la tipologia Jun viene menzionata
Exploring the binding site of C-terminal Hsp90 inhibitors
No full textThe 90 kDa heat shock protein (Hsp90) is a prominent target for anticancer drug discovery. While its N-terminal domain has been widely exploited, several lines of evidence are emerging in favor of targeting its C-terminal domain to conceive innovative drugs based on perturbation of the dimer interface. Here, we describe the application of several computational approaches useful to predict the location of the C-terminal binding site
