ABSTRACT The difficulty in the powder reuse favors the study of materials in the form of thin films. ZnO based films have high photocatalytic potential. In this work, ZnO:xSm3+ (x = 0, 1, 2 and 4 %mol) thin films were prepared by spin coating method. The resins obtained to manufacture the thin films were prepared by complex polymerization method. The samples were characterized by X-ray diffraction (XRD), atomic force microscopy (AFM), field emission scanning electron microscopy (FE-SEM) and spectroscopy UV-Vis. XRD patterns indicate that doping with 4%Sm forms Sm2O3 as the secondary phase. FE-SEM images of the cross section of thin films indicated a uniform thickness ranging from 354 to 367 nm between samples. The incorporation of Sm3+ ions in the ZnO lattice increases the Egap of the films. The photocatalytic performance of the films was tested with the photodegradation of methylene blue dye. Pure ZnO and ZnO:1%Sm3+ exhibited the best activity in the photodegradation. Thin films of pure ZnO exhibit the best photocatalytic results for the first cycle, but considerably reduce their efficiency with reuse. Sm3+ incorporation, without secondary phase formation, was efficient for the maintenance of the photocatalytic property after 3 cycles.

Resumo Objetivo Relacionar a adesão aos antidiabéticos orais e o controle metabólico de pessoas com Diabetes mellitus tipo 2. Métodos Estudo analítico, realizado com 201 participantes, de ambos os sexos, com idade acima dos 18 anos e diagnóstico de diabetes mellitus tipo 2, acompanhados em unidades básicas de saúde. Foram analisadas variáveis sociodemográficas, antropométricas, clínicas, relacionadas à adesão medicamentosa e ao controle metabólico. Para verificar a adesão à terapêutica medicamentosa utilizou-se o Teste de Morisky. Resultados Apenas 23,9% dos participantes foram considerados aderentes ao tratamento medicamentoso, e estes apresentaram, significativamente, melhores níveis de hemoglobina glicada (p=0,048), glicemia de jejum (p<0,001) e colesterol total (p=0,028). Conclusão Houve relação entre a adesão aos antidiabéticos orais e algumas variáveis do controle metabólico, como hemoglobina glicada, glicemia de jejum e colesterol total. Dessa forma, a adesão medicamentosa deve ser, cada vez mais, incentivada entre as pessoas com Diabetes mellitus.

Estudo de caso sobre Cannon de Hermeto Pascoal, obra para flauta, humming na flauta e sons pré-gravados, planejada como uma sessão espírita musical e gravada pelo compositor no disco Slaves Mass (PASCOAL, 1977). A partir do desenho artístico de uma pauta espiralada na capa interna do mesmo LP (PASCOAL e PEREIRA, 1977) e de uma transcrição baseada na faixa gravada, a partitura da obra foi detalhadamente reconstituída e editada (PASCOAL e BORÉM, 2010; incluída neste volume de Per Musi às p.80-82). A combinação das análises formal, escalar e proporcional da partitura e seu cruzamento com a análise espectral da gravação revelam grande unidade e uma íntima relação entre os conteúdos musicais e extra-musicais da obra, na qual elementos opostos dialogam: a improvisação e as camadas de superposição de sons pré-gravados, a sonoridade acústica e os sons manipulados, a performance individual e a coletiva, a estabilidade e a instabilidade modal, as linguagens popular (embolada, jazz modal, free jazz) e erudita (música concreta, atonalismo, cadenza, recitativo), os mundos terreno e espiritual. Apresenta também, em primeira mão, a abordagem analítica do "continuum separação-fusão paradoxal" da obra, a partir de ferramenta etnomusicológica criada e realizada por COSTA-LIMA NETO (2009). Inclui uma contextualização do papel da religião na música do "mago" multi-instrumentista, arranjador e compositor da música popular brasileira.

Case study on Cannon by Brazilian composer, arranger and multi-instrumentalist Hermeto Pascoal, a work for flute, flute humming and pre-recorded sounds, designed as a musical spiritism session and included in the LP Slaves Mass (PASCOAL, 1977). Departing from an artistic drawing of a music staff spiral included in the internal covers of the same LP (PASCOAL e PEREIRA, 1977) and a transcription based on the listening of the track in the same disc, the score of the work was reconstituted and edited in detail (PASCOAL e BORÉM, 2010; included in this issue of Per Musi, p.80-82). The combination of formal, scalar, proportional analyses with the spectral analysis reveal an intimate relation between the musical and extra-musical contents of the work, in which opposing elements dialog: improvisation and the layers of pre-recorded sounds, acoustical sounds and manipulated sonorities, individual and the collective performances, stable and unstable modalities, the popular (the Brazilian embolada, modal jazz, free jazz) and the classical (musique concrète, bimodalism, atonalism, cadenza, recitative) languages, the earth and the spiritual worlds. It presents an original analytical approach of the work based on the "paradoxal separation-fusion continuum", devised and realized by ethnomusicologist COSTA-LIMA NETO (2009). It also includes a context of the religion role in the music of the so-called "mago" (wizard) of the Brazilian popular music.

OBJETIVO: Estudar os fatores determinantes da multirresistência do Mycobacterium tuberculosis às drogas tuberculostáticas em centro de referência de doenças infecto-contagiosas do Estado de Minas Gerais, Hospital Eduardo de Menezes. MÉTODOS: Estudo tipo caso-controle, retrospectivo, realizado de setembro de 2000 a janeiro de 2004. Nesse período, 473 culturas com crescimento de M. tuberculosis relativas a 313 pacientes foram analisadas quanto ao perfil de sensibilidade, no Laboratório Central de Minas Gerais. Foram selecionados os casos multirresistentes definidos como resistência a pelo menos rifampicina e isoniazida, depois de pareados com o grupo controle de pacientes com tuberculose sensível a todas as drogas na razão de 1:3. A associação dos dados demográficos e clínicos foi feita por análise estatística uni e multivariada. RESULTADOS: Durante o período de estudo, doze casos de tuberculose multirresistente foram identificados (3,83%). Na análise univariada, a tuberculose multirresistente foi mais comum no sexo masculino, em pacientes com baciloscopia de escarro positiva, pacientes com cavitações maiores que 4 cm de diâmetro e pacientes com um ou mais tratamentos prévios para tuberculose (p = 0,10). Após a análise multivariada somente o tratamento anterior para tuberculose permaneceu estatisticamente significativo (p = 0,0374), com odds ratio de 14,36 (1,96 - 176,46). CONCLUSÃO: O fator de risco que se mostrou independentemente associado ao desenvolvimento de tuberculose multirresistente neste estudo foi a presença de um ou mais tratamentos prévios para tuberculose.

OBJECTIVE: To assess the determining factors for Mycobacterium tuberculosis multidrug resistance at a referral center for infectious diseases in the state of Minas Gerais, Brazil. METHODS: A retrospective case-control study was conducted using data collected from September of 2000 to January of 2004. During this period, 473 cultures presenting growth of M. tuberculosis, corresponding to 313 patients, were submitted to susceptibility tests at the Central Laboratory of Minas Gerais. Cases presenting resistance to at least rifampin and isoniazid were classified as cases of multidrug resistance and were selected for study. These cases were paired to control group cases of drug-susceptible tuberculosis at a ratio of 1:3. Clinical and demographic data were analyzed using univariate and multivariate analyses. RESULTS: During the study period, 12 (3.83%) cases of multidrug-resistant tuberculosis were identified. In the univariate analysis, multidrug-resistant tuberculosis was found to be more common among male patients, as well as among those testing positive in the sputum smear microscopy, those with cavitations larger than 4 cm in diameter and those having been previously treated for tuberculosis (p = 0.10 for all). After the multivariate analysis, only previous treatment for tuberculosis remained statistically significant (p = 0.0374), with an odds ratio of 14.36 (1.96-176.46). CONCLUSION: In the present study, previous treatment for tuberculosis was found to be an independent risk factor for multidrug-resistant tuberculosis.
