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

In the Wings: Offstage Labour in a Provincial Italian Theatre

The historical archive in Feltre (Veneto) preserves inventories of its Teatro Sociale that testify to this provincial theatre’s importance to the town and the surrounding area during the 19th century. These inventories are rare sources that have never previously been analysed. Based on these documents, this article investigates the world behind the scenes and extracts information on the staff involved in running the theatre. Offstage workers are generally forgotten on playbills and in theatre periodicals (which pay tribute to onstage artists and report the repertoire of travelling theatre companies), and they do not figure significantly in the documents of theatre companies such as contracts, correspondence and regulations. To a greater extent than other sources, these inventories provide a window onto the labour of these workers, who made a highly significant, if less visible, contribution to performances and the running of a theatre

Biocompatibility and antibacterial properties of zirconium nitride coating on titanium abutments: An in vitro study

Improving soft tissue attachment and reducing bacterial colonization on titanium abutments are key factors for the long-term maintenance of healthy soft and hard peri-implant tissues. This in vitro study was conducted to compare the biocompatibility and antibacterial activity of four different surfaces: uncoated Ti6Al4V, anodized, and coated with titanium nitride or zirconium nitride. Surface topography was investigated with a high-resolution system for measuring surface finishes. Human gingival fibroblast (HGF) adhesion and proliferation were examined using MTT assay, Scanning Electron Microscopy (SEM) imaging, immunofluorescence analysis and real-time PCR for selected target genes. The hemolysis and AMES tests were performed to assess the chemical compounds' blood compatibility and mutagenic potential, respectively. Antibacterial activity was tested against five bacterial strains isolated from the oral cavity (Streptococcus salivarius, S. sanguinis, S. mutans, S. sobrinus, S. oralis), and the percentage of dead bacteria was calculated. Roughness measurements confirmed a substantial similarity between the surfaces and their compatibility with clinical applications. MTT assay, SEM analysis and immunofluorescence staining showed adhesion and proliferation of HGFs cultured on all the examined surfaces. PCR confirmed that HGFs produced extracellular matrix components efficiently on all the surfaces. No hemolytic activity was detected, and the AMES test confirmed the surfaces' clinical safety. For all tested bacterial strains, biofilms grown on the zirconium nitride surface showed a higher percentage of dead bacteria than on the other disks. The titanium nitride surface inactivated bacterial biofilms, too, but to a lesser extent

Bioactive sphene-based ceramic coatings on cpTi substrates for dental implants: An in vitro study

Titanium implant surface modifications have been widely investigated to favor the process of osseointegration. The present work aimed to evaluate the effect of sphene (CaTiSiO5) biocoating, on titanium substrates, on the in vitro osteogenic differentiation of Human Adipose-Derived Stem Cells (hADSCs). Sphene bioceramic coatings were prepared using preceramic polymers and nano-sized active fillers and deposited by spray coating. Scanning Electron Microscopy (SEM) analysis, surface roughness measurements and X-ray diffraction analysis were performed. The chemical stability of the coatings in Tris-HCl solution was investigated. In vitro studies were performed by means of proliferation test of hADSCs seeded on coated and uncoated samples after 21 days. Methyl Thiazolyl-Tetrazolium (MTT) test and immunofluorescent staining with phalloidin confirmed the in vitro biocompatibility of both substrates. In vitro osteogenic differentiation of the cells was evaluated using Alizarin Red S staining and quantification assay and real-time PCR (Polymerase Chain Reaction). When hADSCs were cultured in the presence of Osteogenic Differentiation Medium, a significantly higher accumulation of calcium deposits onto the sphene-coated surfaces than on uncoated controls was detected. Osteogenic differentiation on both samples was confirmed by PCR. The proposed coating seems to be promising for dental and orthopedic implants, in terms of composition and deposition technology
