Violence as a research object and intervention in the health field: an analysis from the production of the Research Group on Gender, Health and Nursingi

The study aimed to describe how violence is revealed in the production of the Research Group on Gender, Health and Nursing. This is a historical research of qualitative approach, which evaluated the production of the Research Group, through content analysis. The results show gender as a central category in determining violence and health practices. This aspect determines limitations on professional practices of coping, such as the invisibility of the problem. The female autonomy, the use of alcohol and drugs and social vulnerability play an important relation with the phenomenon and the bond is revealed as potentiality of health practices to address the problem. Conclusion: The gender perspective in nursing research is an innovative field and counter-hegemonic, a possibility to assume a meaning of praxis by transforming potential of understanding and modes of intervention in the phenomenon of gender violence.

Dilatação mediada por fluxo no diagnóstico diferencial da síndrome de pré-eclâmpsia

FUNDAMENTO: A síndrome de pré-eclâmpsia se associa com a disfunção endotelial e o diagnóstico diferencial entre pré-eclâmpsia pura (PE) e sobreposta (PES) só pode ser feito após 12 semanas do parto. OBJETIVO: Comparar a avaliação da função endotelial através de dilatação mediada por fluxo de gestantes com pré-eclâmpsia pura e sobreposta. MÉTODOS: A dilatação mediada por fluxo da artéria braquial foi realizada utilizando as recomendações da International Brachial Artery Reactivity Task Force em gestantes com a Síndrome de Pré-eclâmpsia. Pré-eclâmpsia (n = 14) e pré-eclâmpsia sobreposta (n = 13) foram diagnosticadas no pós-parto segundo as definições do National High Blood Pressure Education Program Working Group on High Blood Pressure in Pregnancy. RESULTADOS: A mediana da dilatação mediada por fluxo (DMF) na PES (6,0%; 1,9-10,3) foi reduzida em comparação com PE (13,6%; 4,4-17,1), uma disparidade aparentemente relevante, mas sem diferença estatisticamente significativa (p = 0,08). A DMF inferior a 10% foi detectada em 30,8% das PE e em 69,2% das PES (p = 0,057). Diferenças significativas não ocorreram na comparação entre a morfologia das artérias uterinas de PE e PES através do espectro do Doppler. CONCLUSÃO: A DMF da artéria braquial de pacientes com Síndrome de Pré-eclâmpsia não se mostrou ser um método capaz de diferenciar PE de PES. Entretanto, os dados sugerem que PES se associa com pior função endotelial em comparação a PE.

Effect of working pressure at different spray nozzles on drift quantification in wind tunnel

Each year, there is an increase in pesticide consumption and in its importance of use in the large-scale agricultural production, being fundamental the knowledge of application technology to the activity success. The objective of the present study was to evaluate the influence of working pressure on the drift generated by different spray nozzles, assessed in wind tunnel. The treatments were composed of two spray nozzles AXI 110015 and AXI 11002 with pressure levels of 276 and 414 kPa. The spray solution was composed by water and NaCl at 10%. The applications were conducted at wind speed of 2.0 m s-1, being the drift collected at 5.0; 10.0 and 15.0 m away from the spray boom and at heights of 0.2; 0.4; 0.6; 0.8 e 1.0 m from the tunnel floor. To both spray nozzles, the greatest drift was collected at the smallest distance to the spray-boom and at the lowest height. The AXI 11002 nozzle gave a smaller drift relative to the AXI 110015 nozzle for the two tested pressures and for all the collection points. Regardless of the nozzle, a rise in the working pressure increases the spray drift percentage at all distances in the wind tunnel.
