Este trabalho apresenta uma discussão a partir da etnografia que foi realizado na unidade Básica de Saúde. Apresentando diversidade de olhares possíveis dentro um evento. Explorando o método etnográfico como ferramenta de observação da dinâmica estabelecida no cotidiano das mulheres que participam dos serviços saúde ofertados na Rede Cegonha de Cuiabá-MT.

The objective of this study is to identify the emergence of notions of health participation, in the public health movement in Brazil. Inspired by Foucault's genealogy, this study hopes to identify specific continuities and find strengths and occurrences within the movement, rather than study the origins and definitions of participation. These will reveal disperse, irregular and strategically planned movements which seek to particimake participation part of policy and create consensus. A search was carried out to identify government and academic documents with the terms "community participation," "popular participation," "social participation," and "political participation." The analysis allows us to describe the linear development of the concept of participation in three important moments. First, the strengthening of the relationship between PAHO and Latin American governments in the '60s, which expanded community participation along with health care coverage. Second is the articulation between different social actors, particularly between health professionals and technicians, and social movements in the '70s, which influenced the design of social and political participation. The third moment coincides with the creation of the Universal Health System (SUS), which seeks to create consensus in social participation. These are not characterized are three separate moments, nor are they lineal or without diversions, but they form part of the process of appropriation and reconstruction of the concept of participation in public health. ; El objetivo del trabajo es identificar la emergencia de la noción de participación en salud en las luchas de la salud en Brasil. Con inspiración en la genealogía foucaultiana, más que investigar los orígenes y definiciones consistentes de participación, esperamos identificar ciertas continuidades, encontrar las fuerzas y acontecimientos que revelan los movimientos dispersos, irregulares, montados estratégicamente para tornar la participación palabra de orden y forjar consensos ...

This paper presents a research that aimed to understand women's participation in public health policy, trough oral history interviews with health of Belo Horizonte. The focus of the research was women's experience of social participation facing the decision-making processes in health. As methodological strategies, besides reviewing the literature on women's participation in struggles for health, interviews were conducted, based on the contributions of oral history. Eight health counselors were involved in the study. The interviews with the counselors were held in two specific moments. At first, we worked with unstructured interviews, favoring an open mode of storytelling. In the second moment, a new interview with each counselor was performed, producing an effect of partial return of data to the interviewees. Social participation, as narrated by the women interviewed is engendered in their life histories, revealing the singular processes of the experience of participation, but at the same time, allowing us to understand their positions on the National Health System and the municipal health council. The data expose the ambiguities and potentialities of the council as a space for mobilization for health, but also as a mode of subjectivity and citizenship building.

Este trabalho discute a contribuição da energia nuclear para a complementação térmica do Sistema Interligado Nacional, as questões relacionadas com a usina Angra 3 em construção e analisa sua contribuição para a sustentabilidade do sistema elétrico. Neste trabalho avalia-se o valor estratégico da segurança energética provido pelas fontes termoelétricas e, em particular, pela alternativa nuclear. A análise de custo é baseada no custo marginal de operação. A análise de sustentabilidade considera 6 critérios: emissão de gases do efeito estufa, área imobilizada, consumo de matéria prima na forma de combustível, consumo de água, morbidade e fatalidades em acidentes. Esses critérios são considerados importantes pelos setores de energia, industrial e pela sociedade. Conclui-se que a energia nuclear na função de complementação térmica garante segurança energética, confiabilidade no fornecimento de energia, menor custo marginal e operação e maior contribuição para sustentabilidade.

Galls formed by root-knot nematodes have been studied in several cultivated species focusing on understanding the intimate relationship between parasite and the host plant. Species of Meloidogyne induce the development of a feeding site in the cortex or vascular cylinder of the host plant and are totally dependent on this site formation to complete their life cycle. Therefore, we focused on anatomical, cytological and histochemical changes during the establishment and development of galls and giant cells induced by Meloidogyne javanica in the roots of Glycine max. Seeds of soybean (susceptible cultivar M8372 IPRO) were sown in trays with coconut fibre substrate and the seedlings were removed ten days after the seeds emerged for nematode inoculation. The roots from inoculated and non-inoculated (control) were sampled at different stages of development until 55 days after inoculation. Histological, cytological, histochemical analysis were performed in light and electron microscopy in non-galled tissue and galls induced by M. javanica. The galls showed different shapes and abundance in the roots inoculated by M. javanica. The induction of galls occurs by hypertrophy of the root cortex shortly after the initial infection process. Giant cells were formed 18 days after nematode inoculation. These giant or nourishing cells are multinucleated, and have a dense cytoplasm, a thick wall with invaginations, many mitochondria and small vacuoles. The anatomical sections indicated a disorganisation of the cells of the cortex and vascular cylinder in relation to the control root.

The objective of this study was to evaluate the effect of the use of different chemical compounds combined with ultrasound bath on the sanitization of minimally processed carrots. The sanitizers sodium hypochlorite, peracetic acid, and sodium dichloroisocyanurate were investigated, all of them associated with the ultrasound bath, and the aerobic mesophiles and E. coli counts were evaluated. Sodium hypochlorite associated with ultrasound reduced the population of aerobic mesophiles and E. coli by 0.23 and 1.88 log cycles, respectively. For sodium dichloroisocyanurate associated with ultrasound, the reduction was 3.06 and 2.76 log cycles, while for the association with peracetic acid, this reduction was 2.72 and 2.35 log cycles. Thus, the effect of the ultrasound bath and sodium dichloroisocyanurate increased the decontamination efficiency of the minimally processed carrots. In addition, there is an alternative to the use of sodium hypochlorite, once they are not involved in reactions with organic compounds and the formation of trihalomethanes, which are harmful to health.
