The mathematical description of the electrosynthesis of composites of oxy-hydroxycompounds cobalt with polypyrrole overooxidazed

The electrosynthesis of the composite with of the overoxidized polypyrrole with cobalt oxy-hydroxide in strongly acidic media has been described mathematically, using linear stability theory and bifurcation analysis. The steadystates stability conditions and oscillatory and monotonic instability requirements have been described too. The system´s behavior was compared with behavior of other systems with overoxidation, electropolymerization of heterocyclic compounds and electrosynthesis of the cobalt oxy-hydroxides

Patogenicidade de Pseudomonas sp. em feijoeiro.

O Brasil se destaca mundialmente entre os maiores produtores e consumidores de feijão?comum (Phaseolus vulgaris L.), cultivado em todo o território, em diferentes condições ambientais. No entanto, a ocorrência de doenças é um dos principais fatores que reduzem a produtividade do feijoeiro. O objetivo deste trabalho foi caracterizar e identificar isolados pertencentes ao gênero Pseudomonas e verificar a patogenicidade desses isolados na cultura do feijoeiro

A False Case of Clozapine-Resistant Schizophrenia

One of the subjects that most concerns physicians is treatment-resistance. About 30%–60% of schizophrenia patients do not respond adequately to antipsychotic treatment and are known as refractory schizophrenia patients. Clozapine has been the drug of choice in such cases. However, approximately 30% of them do not respond to clozapine either. Here, we describe a patient with an initial diagnosis of refractory schizophrenia who had a history of dramatic aggressiveness. However, in this case, “refractoriness” was a wrong diagnosis. A case of psychosis secondary to epilepsy had been treated as schizophrenia for almost 20 years. Reports like this one are important because they remind us of how a thorough investigation can lead to the correct diagnosis and improve the patient's prognosis

Controlling Excitations Inversion of a Cooper Pair Box Interacting with a Nanomechanical Resonator

We investigate the action of time dependent detunings upon the excitation inversion of a Cooper pair box interacting with a nanomechanical resonator. The method employs the Jaynes-Cummings model with damping, assuming different decay rates of the Cooper pair box and various fixed and t-dependent detunings. It is shown that while the presence of damping plus constant detunings destroy the collapse/revival effects, convenient choices of time dependent detunings allow one to reconstruct such events in a perfect way. It is also shown that the mean excitation of the nanomechanical resonator is more robust against damping of the Cooper pair box for convenient values of t-dependent detunings.Comment: 11 pages, 5 figure

Estimativas de parâmetros genéticos via REML/BLUP para o melhoramento intrapopulacional de Platonia insignis Mart.

The aim of this study was to estimate genetic parameters to support the selection of bacuri progenies for a first cycle of recurrent selection, using the REML/BLUP (restricted maximum likelihood/best linear unbiased prediction) procedure to estimate the variance components and genotypic values. Were evaluated twelve variables in a total of 210 fruits from 39 different seed trees, from a field trial with an experimental design of incomplete blocks with clonal replies among subplots. The three variables related with the fruit development (weight, diameter, length) showed strong correlation, and where fruit length showed higher heritability and potential to be used for indirect selection. Among the 39 progenies evaluated in this study, five present potential to compose the next cycle of recurrent selection, due they hold good selection differential either to agrotechnological variables as to development of bacuri fruit

Divergência genética e correlações entre variáveis tecnológicas da população de trabalho de bacuri da Embrapa Meio-Norte.

Estudou-se a divergência genética e as correlações entre as variáveis agroindustriais dos genótipos da coleção de trabalho do bacuri visando à obtenção de população-base para o seu programa de melhoramento genético na Embrapa Meio-Norte. Essa coleção é constituída de 49 genótipos coletados em áreas de ocorrência natural da espécie nos Estados do Piauí e Maranhão. O experimento foi delineado em blocos completos casualizados com 1 planta por parcela e 5 repetições. As variáveis avaliadas foram: peso, comprimento e diâmetro de frutos; relação comprimento/diâmetro de fruto; número de sementes; porcentagens de polpa, de casca e de sementes; sólidos solúveis totais (SS) e acidez total titulável (ATT). Utilizou-se a análise de agrupamento UPGMA para a separação dos genótipos. Considerando-se a distância média entre clusters de 1,0, os genótipos formaram quatro grupos dissimilares. As variáveis diâmetro e comprimento do fruto podem gerar inferências para a variável peso do fruto e promover uma seleção indireta para esta variável

Relationship between the morphogenesis of Italian ryegrass cv. 'BRS Ponteio' with forage and seed production.

This study aims to verify, accurate and precisely, the responses of Italian ryegrass 'BRS Ponteio' cultivar to different frequencies of defoliation for forage production and especially for seed production. For this purpose, a randomized block design experiment with four replications was conducted. Four frequencies of defoliation were applied (zero, one, two, and three) based on the thermal sum, evaluating the rate of leaf appearance (LAR), phyllochron (P), leaf expansion rate (LER), leaf senescence rate (LSR), stems expansion rate (SER), tillering rate (TR), leaf life span (LL), forage production, proportion of leaf blades, stems plus sheaths, senescent material, and inflorescences, as well as seed production. Second defoliation noticeably altered the morphogenic plant responses, reduced expansion rates and leaf appearance, increased rates of tillering and stems expansion. This phenotypic maintained a high seed production and provided a harvest of forage mass 100% higher than the collected mass in the first cutting. Third defoliation led to an increase of 100% of the harvested forage mass; however, it caused drastic and negative changes in the morphogenic characteristics and seed yielding

Novas cultivares brasileiras de uvas para elaboração de suco no Semiárido Brasileiro: desempenho agronômico e qualidade do suco.

Nas últimas décadas, com o aumento da população urbana, observou-se a necessidade da disponibilização de alimentos ao longo do ano, o que tem resultado na produção e comercialização de produtos agrícolas transformados, com maior valor agregado. Seguindo esta tendência, o mercado global de sucos foi estimado em aproximadamente 50 bilhões de litros ao final dos anos 1990. Somente nos Estados Unidos da América, o comércio varejista de sucos alcançou 20 bilhões de litros, movimentando valores da ordem de 18 bilhões de dólares. O mercado mundial cresceu ao longo da última década, com os países em desenvolvimento atingindo mais de 60% das exportações de suco de frutas.bitstream/item/158230/1/Circular-Tecnica-961.pd
