Nè melindrosa nè almofadinha. Modelli di femminilità e di mascolinità nel movimento anarchico a San Paulo (1899-1935)
La donna melindrosa e l’uomo almofadinha ritraggono due modelli di comportamento che si diffusero in Brasile nel primo dopoguerra, come in molti altri Paesi, in nome della modernità. Il movimento anarchico li considerò non come segni di progresso, bensì come ulteriore conferma dei ruoli tradizionali di genere: soprattutto la melindrosa, al di là delle apparenze di libertà, rimaneva quell’essere frivolo e capriccioso che tanto piaceva agli uomini. Oggetto della ricerca è il movimento anarchico che si sviluppò principalmente tra São Paulo e Rio de Janeiro. Il periodo preso in esame inizia con una rappresentazione teatrale (Casa di bambola di Ibsen, São Paulo 1899) e finisce con un dibattito a proposito di un film sull’educazione sessuale (São Paulo, 1935). La scelta delle date, che dimostra l’importanza dei fenomeni culturali nel definire i rapporti tra uomo e donna, rivela la persistenza dell’anarchismo, nel campo dei dibattiti sulla morale sessuale, anche dopo la sconfitta del movimento nei luoghi di lavoro e nelle strade.
La tesi analizza i modelli di femminilità e di mascolinità che emergono nei discorsi e nelle pratiche – nella stampa, nella sociabilità, nelle mobilitazioni, nell’iconografia e nel teatro –, mettendo in luce lo scarto tra modelli ideali e comportamenti quotidiani che si possono osservare in casa, nel lavoro e nel tempo libero all’interno dei quartieri operai. Partendo dal riconoscimento del carattere sessuato dell’anarchismo, la ricerca ricostruisce inoltre l’analogia tra ritualità del movimento ed esperienza della lettura nei militanti, al fine di cogliere i legami tra rappresentazioni del corpo, bellezza sessuata e immagini di società ideale. La trasformazione radicale della società immaginata dall’anarchismo avanzava l’esigenza di nuovi rapporti tra individui: analizzarli, significa mettere in luce i rapporti tra sociabilità, militanza e genere
Festa e lettura nel movimento anarchico a São Paulo (1900-1935): analisi di un rito
L’articolo propone un’analogia tra il rituale della partecipazione alle serate di propaganda promosse dal movimento anarchico e la lettura dei periodici libertari a São Paulo nei primi decenni del Novecento. I due riti sono entrambi esperienze liminali in cui il militante si separa dal presente per mettere in scena l’alternativa e il desiderio; al termine del rito viene reintegrato, con una diversa consapevolezza, in una comunità transnazionale basata sulla solidarietà e su comuni ideali

Bioactive Sphene Coatings for Dental Implant Applications Rivestimenti bioattivi a base di sphene per impianti dentali
Over the last few decades, due to the aging of the population, prolonged life expectancy and increased demand for esthetic dental procedures, there is an increasing request for dental implant treatment for the replacement of missing teeth. In addition, in presence of an inadequate amount of bone for implant positioning, bone regeneration procedures are required. Among various strategies, which are currently being investigated, synthetic biocompatible three-dimensional structures, known as “scaffolds”, produced using different additive manufacturing technologies are attracting growing attention for use in bone tissue regeneration, as personalized bone scaffolds can be designed to fit specific bone defects.
Successful use of bioactive ceramics, as coating materials for dental implants as well as bone substitutes, has been reported. In particular, sintered hydroxyapatite (HA) has been extensively employed in clinical dental practice. However, its low fracture toughness and the occurrence of delamination at the interface with titanium substrates have significantly limited the scope of clinical applications. More recently, a new category of bioactive ceramics, i.e. silicate-based ceramics, has received great attention, due to their remarkable bioactivity and good mechanical properties.
The primary aim of the current project is to develop and test in vitro and in vivo a specific bioactive silicate-based ceramic, sphene (CaTiSiO5), as coating material for dental implants. Sphene coatings will be prepared using a preceramic polymer containing nanosized active fillers as precursors for the formation of the desired ceramic phase. Coating will be applied by airbrushing, and the samples will undergo heat treatment, in order to transform the precursors into a ceramic coating. Once the sphene-coated implants will be prepared, they will be fully characterized in terms of microstructure analysis, crystalline phase assemblage, physicochemical properties, effect on mesenchymal stem cell behavior in vitro, and, finally, osseointegration in a rat model.
Secondary aim of this project consists in the production and characterization of sphene ceramic scaffolds to be utilized as bone substitutes for bone tissue regeneration. These scaffolds will be fabricated by direct ink writing using a preceramic polymer and nano sized active fillers. The samples will be then characterized, and a particular attention will be given to investigating in vitro cytocompatibility and osteoconductive properties, prior to in vivo study using rat critical size calvarial defect model
Né "melindrosa", né "almofadinha". Femminilità e mascolinità nel movimento anarchico in Brasile (1899-1935)
Neither "melindrosa" nor "almofadinha". Femininity and masculinity in the Brazilian anarchist movement (1899-1935)
The woman so called "melindrosa" and her equivalent, the man so called "almofadinha", indicate two examples of behaviour that spread in Brazil in first post war period, as in many other countries, in the name of modernity. The anarchist movement considered them not a symbol of progress, but as another confirmation of traditional gender roles: especially the "melindrosa", beyond an apparent freedom, was the frivolous and capricious woman that men loved yet. This research analyses the anarchist movement developed within São Paulo e Rio de Janeiro. The reference period starts with a drama (Ibsen’s "A doll's house", São Paulo 1899) and finishes with a debate regarding a movie about sexual education (São Paulo, 1935): there two dates demonstrate that cultural phenomenon are important when you try to describe man and woman relationships, but also reveal the existence of anarchism after his defeat in labour and public spaces.
By observing femininity and masculinity models emerging from speeches and experiences – press, sociability, mobilization, iconography and theatre –the thesis reveals the variance between ideal models and ordinary behaviours that occur at home, at work and in the free time inside labour neighbourhoods. Starting from the anarchist sexual character, the research also reconstructs the analogy between movement rituality and reading experience, in order to understand what links body representations, sexual beauty and ideal society images. Radical modification of society conceived by anarchism required a new kind of relationship among people: to analyse this relationship means to cast light on sociability, activism and gender

Clinical and radiographic outcomes of extra-short implants (≤ 6 mm) in the posterior atrophic jaws: a retrospective cohort study
Objective: This study aimed at investigating implant survival rate and marginal bone loss (MBL) around extra-short implants. The impact of the loading protocol and of the use of an intermediate abutment was also evaluated, to explore possible differences in terms of the outcome measures. Materials and methods: Patients with single or multiple mandibular or maxillary posterior edentulism rehabilitated using extra-short 5-6 mm long implants were included. Different prosthetic protocols were used. Clinical and radiological follow-up was 5 years. The outcomes measures were implant survival and MBL. Results: The analysis included 56 implants placed in 34 adults (12 males and 22 females; mean age 60 years, SD 11). Six implants failed during a median follow-up of 5 years and 4 of them were recorded in one patient at 2-year follow-up. The 5-year implant survival was 89% overall (87% in conventional and 94% in immediate loading). At univariate analysis, during follow-up immediate loading was associated with higher MBL (mean variation 0.21 mm, 95%CI 0.01 to 0.40; p = 0.02), while intermediate abutment was associated with lower MBL (mean variation -0.23 mm, 95%CI -0.39 to -0.09; p = 0.003). Multivariable analysis confirmed that immediate loading was associated with higher MBL. Conclusion: Within its limitations, this study showed that extra-short implants under immediate loading conditions can be a reliable solution. The application of horizontal and vertical platform switching with the use of intermediate abutments seems to be able to contribute to the reduction of MBL
