Combined inoculation of rhizobia on the cowpea development in the soil of Cerrado
ABSTRACT Biological nitrogen fixation (BNF) plays an important role in the cowpea cultivation. This study aimed to assess the foliar levels of chlorophyll and the yield components of cowpea subjected to combined inoculation of rhizobia in Cerrado soil. The experiment was carried out in field conditions, from December of 2014 to the march of 2015, in Rondonópolis, Mato Grosso, using randomized block design with ten treatments and three replicates. Were tested the single strains MT8 and MT15 (both of R. tropici), MT16 (R. leguminosarum), BR3267 (Bradyrhizobium japonicum), the strains combinations MT8+MT15, MT8+MT16, MT15+MT16, and MT8+MT15+MT16, nitrogen fertilization (70 kg ha-1 of N-urea), and absolute control (without inoculation of rhizobia and without nitrogen fertilization). Data were subjected to analysis of variance and the averages were compared by orthogonal contrast and F test (p≤0.05). Were assessed the Falker chlorophyll index (at the 40 and 60 days after sowing), number and dry matter of nodules (at the 40 days after sowing), number of pods per plant, grains yield, the concentration and accumulation of nitrogen in grains, and crude protein. The number of pods per plant was increased 33.6% in the combination MT8+MT15. The same effect was observed for the yield grain, which presented an increase of 8.7%, 13.8%, and 16.7% in the combinations MT8+MT16, MT15+MT16, and MT8+MT15, respectively. The nitrogen accumulation in the grains increased 42.7% with the inoculation of MT15 strain. The cowpea responds positively to the usage of combinations of rhizobia strains

Geomorphology map of the Buriti Vermelho Basin
A área selecionada para a realização deste estudo foi a Bacia Hidrográfica do Rio Buriti Vermelho, que está localizada na parte sudeste do Distrito Federal, cujo objetivo foi caracterizar e cartografar as distintas unidades de compartimentação geomorfológica na região, com o intuito de colaborar para um melhor manejo da área. Foram empregadas técnicas de geoprocessamento e trabalhos de campo para a caracterização dos compartilhamentos geomorfológicos. Foram delimitadas as seguintes unidades geomorfológicas: Rampas de Colúvio Curso Superior (52%): Rampas de Colúvio Curso Médio (31%); Rampas de Colúvio Curso Inferior (6%); Topos Convexos (5%); Zona de Nascente (2%); Planície Aluvionar (1%); Vale Curso Inferior (1%); Vale Curso Médio (1%); e Vale Curso Superior (1%). _________________________________________________________________________________ ABSTRACTThe area selected for this study was the Buriti Vermelho Basin, that is located in southeast portion of the Federal District. This study had the propose of to characterized and to map the geomorphologic units for landscape management. In this paper was utilized image processing techniques and field survey to characterize geomorphologic units. Nine geomorphologic init were characterized: Superior Colluvionar Slopes (52%); Medium Colluvionar Slopes (31%); Inferior Colluvionar Slopes (6%); Convex Tops (5%); Headsprings Zone (2%); Alluvionar Plain (1%); Inferior Valley (1%); Medium Valley (1%); and Superior Valley (1%)

Key issues in the management of cervical cancer: consensus recommendations by a Brazilian expert panel
Objective: We report the results of a panel of Brazilian experts and provide recommendations for the management of these patients.
Material and Methods: The panel convened composed by 28 local opinion leaders, addressed 59 multiple-choice questions taking into account the published scientific literature and their own clinical experience. The level of agreement among panel members was qualified as (1) consensus, when at least 75% of the voting panel members; (2) majority vote (50%-74.9%); or (3) less than majority vote.
Results: There was at least majority vote for eight of 10 questions on staging and follow-up; for 14 of 23 questions on the treatment of early-stage disease; for 12 of 14 questions related to the treatment of locally-advanced disease; and for seven of the 12 questions related to the treatment of recurrent/metastatic disease.
Conclusion: The current recommendations may help practitioners from Brazil and other countries to improve the care they provide to patients
