Application rate and nozzles associated with droplet electrification affect the spraying quality in common bean.

Abstract: The objective of this work was to evaluate the application efficiency of different nozzle tips associated with increasing application rates. A field experiment was conducted in a factorial 3 × 4 randomized block design with four replicates. The first factor consisted of three types of nozzle tips (simple flat fan, hollow cone, and hollow cone with the electrification of the drops), and the second factor constituted the four application rates (50, 100, 200, and 250 L ha-1). Electrostatic technology and a hollow cone tip increased the deposited volume on leaves on the upper and medium strata of the common bean plant, regardless of the application rate used. The increase in the application rate increased the volume of spray solution captured in the upper, medium, and lower strata, the drop density, the volumetric median diameter (VMD), and the percentage of foliar coverage, regardless of the spray tip evaluated. The percentage of leaf coverage on the adaxial and abaxial leaf was not influenced by the simple fan or hollow cone spray tips, with or without the association of electrostatic technology

Microbiol diversity in rhizosphere resistant and susceptible guarana collected in Maués and Manaus.

The rhizosphere is the soil region subject to influence of exudates released by plants and microorganisms (epiphytic and endophytic). In addition, this region has large variety of bacteria that can contribute to plant growth and/or inhibiting the activity of plant pathogens. The culture of guarana (Paullinia cupana var. Sorbilis (Mart.) Ducke) is threatened by the presence of the fungus Colletotrichum guaranicola Albuq. and Fusarium decencellulare Brick, causal agents of anthracnose and overbudding, respectively. In this work, the metabolic diversity of rhizospheric bacteria was studied in resistant (R) and susceptible (S) clones collected in Manaus (Mn) and Maués (Mu)

METHODS AIMED AT REDUCING THE RESIDUAL RISK OF PATHOGEN TRANSMISSION DURING PLATELET TRANSFUSION: A LITERATURE REVIEW

Objective: In the Brazilian public health system, sterile filtration is often used to prevent infections associated with platelet transfusion. The literature addressing this issue indicates that pathogen inactivation could be incorporated as an alternative to the development of individual tests and blood donor selection. The objective was to assess whether the use of platelets submitted to pathogen inactivation by photochemical methods could decrease the incidence of post-transfusion infections by viruses, bacteria or other pathogens compared to the use of platelet concentrate or platelets extracted by apheresis without photochemical treatment.Methods: A literature review from 1998 to 2015 was conducted. The scientific literature was surveyed using six electronic databases, two Internet search tools and a manual search of references, using specific search strategies for each database. The selected studies were assessed for quality according to a specific methodology. Data analysis was performed by observations made from the efficacy of the methods.Results: From a detailed analysis of 426 articles retrieved, 10 articles were selected for this review. Among the selected studies, seven studies were clinical trials, and three studies were systematic reviews in combination with meta-analysis. The outcomes analyzed included the reduction of the residual risk in pathogen transmission, mortality, occurrence of hemorrhagic events, corrected count increment (CCI) after 1 h, CCI after 24 h, and transfusion reactions.Conclusion: Differences were found in the quality of the included studies. Systematic reviews conducted on this topic, in alliance with political, social and administrative factors, will aid decision makers regarding its incorporation into the Brazilian Health System.Keywords: Blood Platelets, Platelet Transfusion, Platelet Transfusion/methods*, Riboflavin, Ultraviolet Rays, Photosensitizing Agents, Platelet Transfusion/adverse effect

Solos dos reassentamentos rurais da Usina Hidrelétrica de Manso, Município de Chapada dos Guimarães, Estado de Mato Grosso.

O objetivo do trabalho foi realizar o estudo dos solos dos reassentamentos rurais da usina hidrelétrica de Manso, no Município de Chapada dos Guimarães, visando proceder à identificação, caracterização e cartografia dos solos. Os procedimentos utilizados consistiram na delimitação dos principais domínios e/ou padrões fisiográficos, a partir da fotointerpretação de fotografias aéreas, de dados de sensores remotos e do modelo digital de elevação (MDE), principalmente dos dados de altimetria e de declividade. Esse material apoiou a prospecção e cartografia dos solos no campo e verificação dos limites entre as unidades de mapeamento. No domínio das terras baixas, foram identificados Neossolos Quartzarênicos Hidromórficos, Plintossolos Háplicos Distróficos e Argissolos Vermelhos Distróficos plínticos. Ocupando as posições mais elevadas da paisagem, foram identificados Neossolos Quartzarênicos órticos típicos e latossólicos, Latossolos Vermelhos e Vermelho-Amarelos Distróficos típicos e eventualmente plínticos, Nitossolos Vermelhos Distróficos, Plintossolos Háplicos, Plintossolos Pétricos, Argissolos Vermelhos típicos e plínticos, Argissolos Vermelho-Amarelos abrúpticos e plínticos, Neossolos Litólicos e Cambissolos Háplicos Distróficos que ocorrem associados a afloramentos de rochas. As principais restrições pedológicas observadas na área compreendem a baixa fertilidade natural dos solos e a elevada suscetibilidade à erosão, em consequência da elevada precipitação e do relevo da área. Essas características influenciam no comportamento dos solos frente aos diferentes tipos de usos e práticas de manejo, devendo ser consideradas no planejamento de uso dos solos.bitstream/item/204395/1/CNPS-BPD-101-2006.pd

Atomic mass dependence of \Xi^- and \overline{\Xi}^+ production in central 250 GeV \pi^- nucleon interactions

We present the first measurement of the atomic mass dependence of central \Xi^- and \overline{\Xi}^+ production. It is measured using a sample of 22,459 \Xi^-'s and \overline{\Xi}^+'s produced in collisions between a 250 GeV \pi^- beam and targets of beryllium, aluminum, copper, and tungsten. The relative cross sections are fit to the two parameter function \sigma_0 A^\alpha, where A is the atomic mass. We measure \alpha = 0.924+-0.020+-0.025, for Feynman-x in the range -0.09 < x_F < 0.15.Comment: 10 pages, revtex, 2 figures, submitted to Phys. Rev.

A gente vive equilibrando pratos: olhares sobre a violência que interroga a rede pública de saúde mental do município do Rio de Janeiro

Este artigo buscou caracterizar a rede de saúde mental do município do Rio de Janeiro e compreender os caminhos, práticas e discursos voltados à atenção prestada às pessoas em situação de violência que chegam a esses serviços. Realizou-se um estudo exploratório de abordagens quantitativa e qualitativa que abordou profissionais e gestores em 22 unidades de saúde mental. Como resultado identificou-se a produção de conhecimentos e estratégias para lidar e intervir nas situações tendo como efeitos a interrupção do ciclo de violência, entretanto estas ações têm pouca visibilidade em toda a rede de saúde e estão pouco integradas às diretrizes da Política Nacional de Redução da Morbimortalidade por Acidentes e Violências (PNRMAV). Conclui-se que a atenção na área da saúde mental às vítimas da violência vem sendo realizada, entretanto, de forma não integrada à PNRMAV o que expõe lacunas importantes
