ABSTRACT The São Francisco Sub medium Valley is a great mango exporter in Brazil. In this semiarid region, diseases such as dieback and mango malformation have reduced the production of this crop. In this work the effectiveness of different active ingredients (flutriafol, methyl-thiophanate, copper hydroxide and fluxapyroxad mixed with pyraclostrobin) was assessed for the control of these diseases in a mango orchard. Monthly assessments of disease incidence were carried out. There was a difference among treatments for the two diseases studied, with flutriafol as the most effective fungicide against dieback and, for the malformation, the mixture of fluxapyroxad and pyraclostrobin and methyl-thiophanate showed the best results. Brazil region crop flutriafol, (flutriafol methylthiophanate, methylthiophanate methyl thiophanate, thiophanate orchard out studied results

SUMMARY OBJECTIVE: Several prospective randomized trials have shown that hypofractionation has the same efficacy and safety as the conventional fractionation in the treatment of localized prostate cancer. There are many benefits of hypofractionation, including a more convenient schedule for the patients and better use of resources, which is especially important in low- and middle-income countries like Brasil. Based on these data, the Brazilian Society of Radiotherapy (Sociedade Brasileira de Radioterapia) organized this consensus to guide and support the use of hypofractionated radiotherapy for localized prostate cancer in Brasil. METHODS: The relevant literature regarding moderate hypofractionation (mHypo) and ultra-hypofractionation (uHypo) was reviewed and discussed by a group of experts from public and private centers of different parts of Brasil. Several key questions concerning clinical indications, outcomes and technological requirements for hypofractionation were discussed and voted. For each question, consensus was reached if there was an agreement of at least 75% of the panel members. RESULTS: The recommendations are described in this article. CONCLUSION: This initiative will assist Brazilian radiation oncologists and medical physicists to safely treat localized prostate cancer patients with hypofractionation.

RESUMO Objetivo investigar a forma de oferta de dieta, conforme os diversos métodos de alimentação, e descrever o ganho de peso em recém-nascidos com microcefalia relacionada ao Zika Vírus, comparando-os com recém-nascidos sem microcefalia. Método estudo de coorte retrospectivo com caso controle aninhado. Informações sobre idade gestacional, peso e métodos de alimentação (seio materno, sonda nasogástrica/orogástrica, mamadeira e copo) foram coletadas em prontuários de 43 recém-nascidos com microcefalia por Zika Vírus, equiparados conforme idade gestacional com 43 recém-nascidos sem acometimentos (grupo controle), em uma maternidade de referência no Nordeste do Brasil. Os dados foram coletados desde o nascimento até a alta hospitalar. As medidas de desfecho foram pesos (ao nascer e na alta), velocidade de ganho de peso, tempo de internação e métodos de alimentação. Resultados O grupo com microcefalia apresentou menores pesos ao nascer (D=-1,67; p<0,001), inclusive com maior probabilidade de serem baixo peso (Phi=0,687; p<0,001), e no momento da alta (D=-0,87; p=0,006), do que o controle. O grupo com microcefalia também apresentou maior velocidade de ganho de peso (D=0,77; p=0,006), embora com métodos alimentares semelhantes ao grupo controle, incluindo a aceitação do seio materno, de forma exclusiva (34,9%) ou complementada (58,1%). Conclusão recém-nascidos com microcefalia relacionada ao Zika Vírus utilizaram métodos alimentares semelhantes, incluindo seio materno, aos do grupo sem acometimento. Quanto ao peso, apresentaram valores menores ao nascimento e na alta, apesar de terem um crescimento precoce pós-natal mais rápido que aqueles sem microcefalia.

ABSTRACT Purpose Investigate the form of diet offer, according to the different feeding methods, and describe the weight gain in newborns with microcephaly related to Zika Virus, comparing them with newborns without microcephaly. Methods Retrospective cohort with nested case-control study. Information on gestational age, weight and feeding methods (maternal breast, nasogastric/orogastric tube, bottle and cup) were collected from medical records of 43 newborns with microcephaly due to Zika Virus, matched according to gestational age with 43 newborns without involvement (control group), in a reference maternity hospital in northeastern Brazil. Data were collected from birth to hospital discharge. Outcome measures were weights (at birth and at discharge), weight gain speed, length of hospital stay and feeding methods. Results The microcephaly group had lower weights at birth (D=-1.67; p<0.001), even more likely to be underweight (Phi=0.687; p<0.001), and at discharge (D=-0.87; p=0.006), than the control group. The microcephaly group also showed a higher rate of weight gain (D=0.77; p=0.006), although with eating methods similar to the control group, including acceptance of the mother’s breast, exclusively (34.9%) or complemented (58.1%). Conclusion Newborns with Zika Virus-related microcephaly used similar feeding methods, including maternal breast, to those in the non-affected group. As for weight, they showed lower values at birth and at discharge, despite having a faster postnatal early growth than those without microcephaly.

Nos tratores agrícolas, o deslizamento dos rodados ocorre por diversos fatores, entre eles o esforço de tração necessário para deslocar determinado implemento e o tipo de superfície que está em contato com a banda de rodagem dos pneus. Este trabalho tem o objetivo de avaliar o deslizamento do rodado de pneus de um trator em diferentes sistemas de preparo do solo na cultura do milho, no município de Bambuí, Estado de Minas Gerais. O experimento foi conduzido a campo, na safrinha outonal de 2011, na Fazenda Varginha, do Instituto Federal Minas Gerais - campus Bambuí, em um Latossolo Vermelho distroférrico típico. O experimento foi montado em esquema de parcelas sub-subdivididas, tendo, nas parcelas, as operações, nas subparcelas as marchas e, nas sub-subparcelas, as rotações, no delineamento em blocos casualizados, com três repetições, totalizando 81 unidades experimentais. Os fatores e níveis estudados foram (PC) preparo convencional, (CM) cultivo mínimo e (PD) plantio direto. Para cada tratamento, foram utilizadas três marchas (A2, A3 e B1), em três rotações (1600, 1900 e 2200 rpm). Pelos resultados, conclui-se que, no preparo convencional, o maior índice de deslizamento ocorre na operação de semeadura; no cultivo mínimo, na operação de escarificação e, no plantio direto, na operação de semeadura.

In tractors, the wheel sliding is caused by several factors, including the tractive effort required to move a certain implement and type of surface that is in contact with the tire treads. This study aimed at evaluating the wheel sliding of a tractor in different corn tillage systems in Bambuí, MG, Brazil. The experiment was conducted in the field in the second crop of autumn 2011 at the Minas Gerais Federal Institute - campus Bambuí (Experimental Station) in an Oxisol Ustox. The experiment was arranged in split-plots, with the operations in the plots, the gears in the splitplots and rotations in the split-splitplots, in a randomized block design with three replications, totaling eighty-one experimental units. The factors and levels studied were: (CT) conventional tillage (MT), minimum tillage (NT) and no tillage. Each treatment used three run speeds (A2, A3 and B1) in three motor rotations (1600, 1900 and 2200 rpm). The results showed that in the conventional tillage, the highest wheel sliding occurs in the sowing operation; in the minimum tillage, the highest wheel sliding occurs in the operation of scarification; and in no tillage system in the sowing operation.

A produtividade do feijoeiro no Brasil é considera baixa entorno de 820 kg ha-1, podendo atingir valores acima de 3.000 kg ha-1, vários fatores ambientais podem limitar o bom desempenho da cultura, principalmente os relacionados ao solo. Sendo assim objetivou-se com a realização deste trabalho avaliar a compactação do solo na cultura do feijoeiro em diferentes sistemas de manejo do solo, por meio de imagens digitais. Este trabalho foi realizado na Universidade Federal de Viçosa, utilizou-se o delineamento em blocos ao acaso com seis repetições, sendo quatros tratamentos avaliados (plantio direto, preparo convencional, cultivo mínimo utilizando grade niveladora-destorroadora e cultivo mínimo utilizando escarificador). Foram avaliados a resposta espectral utilizando índices de vegetação (NDVI, RS, GNDVI, VARI, WDRVI e SAVI), calculados a partir dos valores dos números digitais das imagens e dos valores estimados da reflectância. Para aquisição das imagens foi utilizado uma plataforma contendo duas câmeras digitais, uma sensível na região do visível (RGB) e a outra sensível na região do infravermelho próximo, esta plataforma foi acoplada a um balão inflado com gás hélio. Os índices de vegetação obtidos a partir dos valores dos números digitais das imagens só foram capazes de diferirem os tratamentos aos 70 dias após o plantio. Os índices obtidos pelos valores estimados da reflectância diferiram os tratamentos aos 34 e 70 dias após o plantio.

Bean yield in Brazil is considered low, around 820 kg ha-1, reaching values above 3000 kg ha-1, there are several environmental factors which may limit the performance of this culture, especially those related to the soil. The present work aimed to evaluate soil compactions in bean culture of different soil management systems, by means of digital images. This study took place at the Federal University of Viçosa, randomized block design with six replications was used and four treatments, (direct planting, conventional preparation, minimum plantation using grade crusher-leveler and minimum plantation using scarificator), were evaluated. The spectral responses using the vegetation indexes (NDVI, RS, GNDVI, VARI, WDRVI and SAVI) were evaluated, calculated from digital numbers of the images and the values were estimated from the reflectance. For obtainning the images, a platform containing two digital cameras, one sensitive in the region of visible (RGB) and another sensitive to the region of proximal infrared were used, this platform was attached to a helium-inflatable balloon. The vegetation indexes obtained from the values of digital numbers of images were only able to defer treatments 70 days after plantation. However, indexes obtained from the reflectance, deferred treatments at 34 and 70 days after planting.
