Mesoporous gamma-aluminas (γ-Al2O3) were synthesized starting from an unusual precursor of polyoxohydroxide aluminum (POHA). This precursor was obtained from aluminum oxidation in alkaline water-ethanol solvent in the presence of d-glucose that induces the formation of a gel, which leads to the POAH powder after ethanolic treatment. Precipitated POHAs were calcined at different temperatures (300, 400, 700 and 900 °C) resulting in the metastable γ-Al2O3 phase. Whereas at 300 °C no γ-Al2O3 phase was formed, unexpectedly, mesoporous γ-Al2O3 was obtained at 400 ºC having a high specific surface area (282 m2/g) and a narrow pore size distribution. At higher temperatures, the aluminas had the expected decrease in surface area: 166 m2/g (700 °C) and 129 m2/g (900 °C), respectively. The structural change from POHA to alumina calcined at 400 ºC occurs directly without the need to isolate the hydroxide or oxyhydroxide aluminum precursors. Both POHA and transition aluminas were characterized by Fourier Transform Infrared spectroscopy (FTIR), X-ray diffraction (XRD), N2 sorption and Scanning Electron Microscopy (SEM). These findings show an alternative route to produce high standard aluminas.

A Faculdade de Medicina de Marília (Famema) é reconhecida por favorecer o ensino baseado na prática e centrado no estudante. Os estudantes são inseridos em Unidades de Saúde da Família (USF), onde interagem com a comunidade no desenvolvimento de ações - reflexões - ações, por meio da realização de visitas domiciliárias durante os dois primeiros anos dos cursos de Enfermagem e Medicina. Tais visitas são consideradas ferramentas para a compreensão e o cuidado em necessidades de saúde da família. Dessa maneira, elas têm por objetivo englobar os aspectos sociais, psicológicos e econômicos do indivíduo. Objetivo: Esta pesquisa avalia comparativamente a opinião dos estudantes e das famílias que realizaram e receberam visitas domiciliárias. Métodos: Trata-se de um estudo descritivo e quantitativo que informa a opinião das famílias e dos estudantes a respeito das visitas domiciliárias. Conclusões: As famílias e os estudantes consideram importante a valorização e o aprimoramento da prática, visando à construção humanizada do processo saúde-doença, incentivando, desde o princípio, a formação acadêmica e o vínculo integral entre profissional da saúde e paciente.

The Marilia Medical School (Famema) is known for promoting practice-based and student-centred teaching. Students are placed in different Family Health Units (USF), where they can interact with the community in the development of action - reflection - action by performing home visits during the first two years of the Nursing and Medicine courses. Home visits are considered tools for understanding and caring for family health needs and as such embrace the social, psychological and economic aspects of the individual. Objective: This research investigated and compared the opinions of the student visitors and families who received home visits. Methods: This descriptive and quantitative research informs the opinions of the families and students about the visits. Conclusions: The families and students think it is important to continue investing in and improving this practice, aiming toward a humanized construction of the health-disease process and encouraging stronger ties between the health professional and patient since the start of medical academic education.
