Third-order nonlinear optical properties of Ge-As-Te chalcogenide glasses in mid-infrared
Authors: Li Qiuli , Wang Rongping , Xu Fu , Wang Xunsi , Yang Zhiyong , Gai Xin
Published: May 2020

Third-order nonlinear optical properties of
Ge10AsxTe90-x chalcogenide glasses
were investigated utilizing the Z-scan method at the mid-infrared
wavelengths of 2.5 and 3.0 µm. The compositional dependence of
the third-order nonlinearity was analyzed, and their correlation with
the refractive index and the optical bandgap was discussed. The
results show that nonlinear refractive index
n2 can be significantly enhanced by the
addition of tellurium, and larger n2
values are observed at 3.0 µm rather than 2.5 µm
due to the two-photon resonance effect, and the maximum of
n2 is 4.96 ×
10−13 cm2/W at the composition of
Ge10As20Te70. In addition, the
experimental results are in good agreement with the semi-empirical
Miller’s rule whilst the variation of dispersive
n2 values are in relatively good
coincidence with the theoretical model by Sheik-Bahae et.al. for
direct bandgap semiconductors.

Published: May 2020

Background and Aim: The increasing antimicrobial resistance with reduced susceptibility to antimicrobial drugs is becoming a major concern for both human and animal, which raises health morbidity and mortality rate of cases that cannot be treated by antibiotics. Nowadays, there are many efforts to minimize the misuse of antibiotics. This study evaluated the antimicrobial activity of the crude ethanolic extracts of three Thai herbs divided in four groups; petals of marigold (Tagetes erecta), mulberry leaves and root barks (Morus indica), and whole onions of red shallot (Allium ascalonicum) against Streptococcus agalactiae.

Materials and Methods: The antimicrobial activity of four groups of the crude extracts using absolute ethanol from three Thai herbs was tested against standard strains of S. agalactiae using the agar well diffusion method. The commercial antibiotics ceftriaxone and erythromycin were used as positive control standards to determine the sensitivity of S. agalactiae.

Results: The result showed that all four groups of Thai herbal extract had inhibitory activity against standard strains of S. agalactiae. The inhibitory concentration test values were obtained using the dilution test at 25, 50, and 75 mg/ml. The maximum antimicrobial activity against S. agalactiae was observed in the ethanolic extracts from red shallot extract, followed by leaves of mulberry, petals of marigold, and root barks of mulberry, respectively.

Conclusion: The results demonstrated that the crude extract of three Thai herbs had antimicrobial activity inhibiting the growth of S. agalactiae and suggesting that they may be useful in the treatment of S. agalactiae infections in humans and animals.
As marcas da pantera, 25 anos depois...
Authors: Rago Margareth
Published: May 2020

25 anos após a publicação do artigo “As Marcas da Pantera: Michel Foucault na Historiografia Brasileira”, Foucault continua a nos surpreender com suas ousadas reflexões. Recentemente publicado, o livro As confissões da carne completa sua genealogia do sujeito moderno, apontando para dimensões profundamente enraizadas em nossa psique. Sua pesquisa arqueogenealógica sobre os regimes de verdade que regem nossas vidas, amplia-se ao abranger os primeiros anos do cristianismo e ao revelara dívida que este mantém com o estoicismo. Em seus cursos, Foucault traz contundentes reflexões sobre a migração da confissão e do poder pastoral para fora dos muros da igreja e para sua incorporação no Estado moderno, chegando aos nossos dias, marcados pelo neoliberalismo. Coma noção de governo de si e do outro, problematiza novas tecnologias do poder, enquanto as “contracondutas” remetem à maneira pela qual as práticas da liberdade são experimentadas frente à governamentalidade cristã ou neoliberal.
Foucault y la historia de la escolarización: presupuestos teóricos y debates historiográficos
Authors: Dussel Inés
Published: May 2020

En Nietzsche, la genealogía y la historia, Foucault abogó por una historia que haga tajos en el conocimiento establecido y que resista la seducción de las narraciones de reconciliación o consoladoras. Sin embargo, la historiografía educativa tendió a adoptar algunas hipótesis, sobre todo la de la escuela como institución disciplinaria que se presenta en Vigilar y Castigar, que terminaron resultando posiciones cómodas y poco intempestivas, como abogaba Nietzsche. En este artículo propongo una relectura de los planteos foucaultianos sobre la historia de la escuela, y en especial de un trabajo de un autor pos-foucaultiano, Ian Hunter, que publicó en 1994 una obra original sobre la escolarización, así como los debates que suscitó este trabajo. Se busca analizar sus perspectivas historiográficas y sus aportes para una comprensión más rica sobre la emergencia y los efectos de la institución escolar.
L' hydroélectricité du Québec et les grandes régions productrices
Authors: Prémont Marie-Claude , Proulx Marc-Urbain
Published: May 2020

La grande production hydroélectrique du Québec fait la fierté de la population et de ses élites. Trèslargement produite loin des territoires métropolitains de Montréal et de Québec, l’hydroélectricité des régions du Nord-du-Québec, de la Côte-Nord et du Saguenay–Lac-Saint-Jean laisse-t-elle, sur ces territoires, un bénéfice à la hauteur de sa contribution importante à la richesse du Québec? En d’autres termes, la répartition de la rente hydroélectrique, ou sa dissipation, bénéficie-t-elle aux grandes régions productrices, qui comprennent une large part de la ruralité du Québec? Les auteurs estiment que l’histoire du dernier siècle, et particulièrement des dernières décennies, démontre que les retombées locales se sont réduites comme une peau de chagrin.

Published: May 2020

The objective of this work was to investigate the impact of pesticides on the survival of the plant growth- promoting bacteria Azospirillum in the surface of coated seeds as well as in the maize rhizosphere. Our results showed that the greater the time that the bacteria are in
contact with the seed surface, the higher the cell mortality. In uncoated maize seeds, inoculation increased bacterial concentration in root tissues and ensured superior plant growth up to 12 hours of Azospirillum contact with the seed surface, while for the coated seeds, a similar
performance was observed only up to six hours of exposure.

ORIGEN Y DESARROLLO DEL SISTEMA DE EDUCACIÓN TÉCNICO PROFESIONAL (ETP) PARA LA EDUCACIÓN SECUNDARIA EN ARGENTINA Y BRASIL
Authors: Maturo Yanina Débora
Published: May 2020

Desde una perspectiva histórica, este artículo presenta una revisión sobre el origen y desarrollo del sistema de ETP en Argentina y Brasil. A partir de considerar los cambios en las relaciones entre Estado y sociedad se identifican diferentes períodos de desarrollo del sistema de ETP atendiendo a dos categorías teóricas: la evolución del vínculo entre trabajo y sistema de formación y, la consolidación del sistema de ETP en cada país. El análisis se basa en la revisión bibliográfica, donde se hace referencia a los marcos normativos para la ETP diseñados por cada país. Como hipótesis de trabajo se sostiene que la revisión histórica permite visualizar puntos de encuentros, tendencias, que han traspasado las fronteras ingresando como parte de una “red de políticas globales” afectando y direccionando las políticas educativas para la ETP en Argentina y Brasil; sin embargo, rasgos característicos ligados al mismo proceso de surgimiento del sistema de ETP en cada país produjeron diferencias sustanciales en el modo de reestructurar y reorganizar el sistema de ETP a lo largo de la historia y hasta la actualidad.

Published: May 2020

ABSTRACT Background: Hemorrhagic transformation (HT) is a common complication after ischemic stroke. It may be associated to poor outcomes. Some predictors of HT have been previously identified, but there remain controversies. Objective: To describe the risk factors for HT more frequently reported by a panel of experts surveyed for this project. Methods: We sent a standard questionnaire by e-mail to specialists in Vascular Neurology from 2014 to 2018. Forty-five specialists were contacted and 20 of them responded to the invitation. Predictors cited by three or more specialists were included in a table and ranked by the frequency in which they appeared. A review of the literature looking for published predictive scores of HT was performed, comparing to the answers received. Results: The 20 responding specialists cited 23 different risk factors for HT. The most frequent factors in the order of citation were the volume of ischemia, previous use of antithrombotic medication, neurological severity, age, hyperglycemia at presentation, hypertension on admission, and cardioembolism. Most variables were also found in previously published predictive scores, but they were reported by the authors with divergences of frequency. Conclusion: Although many studies have evaluated HT in patients with acute ischemic stroke, the published risk factors were neither uniform nor in agreement with those cited by the stroke specialists. These findings may be helpful to build a score that can be tested with the goal of improving the prediction of HT.

Published: May 2020

Resumo Em situações críticas decorrentes de níveis baixos dos reservatórios das hidrelétricas, o controle do setor elétrico brasileiro é feito com base em planejamento hidrotérmico que dependem das vazões afluentes futuras às Usinas Hidrelétricas (UHEs). As incertezas hidrológicas são consideradas por meio de cenários sintéticos de sequências de energias naturais afluentes às sub-regiões. Dois modelos computacionais são usados para otimizar o sistema: o NEWAVE (médio e longo prazo) e o DECOMP (curto prazo). O NEWAVE é um modelo de planejamento energético aplicado ao Sistema Interligado Nacional (SIN) que utiliza a Programação Dinâmica Dual Estocástica (PDDE) para determinar a política operativa que minimiza o custo marginal de operação em um horizonte de até 5 anos. O desenvolvimento deste trabalho tem como objetivo avaliar o desempenho do NEWAVE através da funcionalidade NWLISTOP na projeção das Energia Natural Afluente (ENA) e da Energia Armazenada (EAR) no Subsistema Nordeste (NE) para os anos de 2012 a 2016. Verificou-se que o modelo tende a superestimar os valores das ENA e EAR. Os resultados indicam a necessidade do uso de técnicas que permitam otimizar o planejamento de operação a longo prazo, principalmente em episódios de seca extrema.

Published: May 2020

Resumo Trabalhos recentes mostram que a assimilação de dados melhora a eficácia dos modelos de previsão de tempo, contudo o impacto da assimilação dos dados de radar é pouco quantificado com relação às parametrizações físicas do modelo, especialmente de microfísica. O objetivo deste trabalho é estudar o impacto do uso de dados de radar com diferentes parametrizações de microfísica do modelo Weather Research and Forecasting (WRF) com seu sistema de assimilação de dados (WRFDA-3DVAR) para casos de precipitação intensa. Foram selecionados três eventos de precipitação em 2014, com área de estudo abrangendo o oeste da região sul do Brasil e sudeste do Paraguai. Desta forma, são avaliados nove esquemas de parametrizações de microfísica com assimilação de dados convencionais e de radar, para determinar qual representa de forma mais adequada a precipitação e refletividade nas previsões de curto prazo, além de determinar o impacto relativo entre as mudanças de microfísica e a assimilação de dados convencionais e de radar. A comparação realizada através da métrica estatística Fractional Skill Score (FSS) mostra o impacto positivo da assimilação de dados do radar foi na média de até 20% no FSS, enquanto que o impacto positivo entre as opções de microfísica atingiu 70%.
Parâmetros Biofísicos de Diferentes Tipos de Cobertura do Solo em uma área de Cerrado no Sul de Mato Grosso
Authors: Ivo Israel Oliveira , Biudes Marcelo Sacardi , Machado Nadja Gomes , Santos Luiz Octavio Fabricio dos , Pedreira Junior Altemar Lopes
Published: May 2020

Resumo O Cerrado apresenta uma variedade de fitofisionomias, com características distintas em estrutura e distribuição, o que contribui para uma heterogeneidade na interação da radiação solar com a superfície. Dessa forma, o objetivo desse estudo foi avaliar a variabilidade espacial e temporal de parâmetros biofísicos em diferentes tipos de cobertura do solo de uma área de Cerrado no sul do estado de Mato Grosso por sensoriamento remoto. Os parâmetros biofísicos índice de vegetação da diferença normalizada (NDVI), o albedo, temperatura da superfície e o saldo de radiação foram obtidos nas fitofisionomias do Cerrado: Campo Limpo, Campo Sujo, Cerradão e Cerrado stricto sensu; e numa área de pastagem. As estimativas foram realizadas com imagens do sensor TM Landsat 5, em 2009, 2010 e 2011. No período chuvoso, o NDVI e o saldo de radiação foram 44% e 15% maiores e o albedo e a temperatura da superfície foram 18% e 12% menores que no seco, respectivamente. Nos locais com maior NDVI e maior saldo de radiação foram encontrados os menores albedo e temperatura da superfície. As diferentes fitofisionomias do Cerrado tiveram interação distinta com a radiação solar em escalas sazonal e espacial devido à variação da cobertura da vegetação e disponibilidade hídrica.
Eventos Extremos de Chuva no Estado do Rio Grande do Sul, Brasil, entre 2004 e 2013. Parte 1: Definição dos Eventos e Estatísticas
Authors: Teixeira Mateus da Silva , Prieto Raidel Báez
Published: May 2020

Resumo Este artigo avaliou os eventos de chuva extrema ocorridos entre 2004 e 2013 no estado do Rio Grande do Sul, Brasil. Os eventos extremos foram separados em duas classes: diários e persistentes, os quais foram identificados por meio das estações meteorológicas do INMET. Para ambas classes de eventos, nenhuma tendência de aumento ou diminuição no número de casos foi detectada. Os eventos extremos diários têm maior frequência na primavera e no verão, enquanto os eventos extremos persistentes têm maior frequência no inverno. A espacialização da chuva, nos casos extremos persistentes, mostrou que a metade leste do estado do Rio Grande do Sul tem maior frequência de eventos de chuva persistente, com grande quantidade de chuva. Em um segundo artigo, os padrões atmosféricos são investigados, bem como a sua relação com a espacialização observada da chuva, obtida neste primeiro artigo.

Published: May 2020

Resumo Nesta segunda parte do estudo sobre eventos persistentes de chuva são avaliadas as condições atmosféricas associadas aos eventos. Compostos de campos diagnósticos são apresentados para os eventos separados em função de sua duração. Eles mostram que sistemas atmosféricos com lento deslocamento propiciam a permanência de áreas de convergência do fluxo de umidade, transporte de calor e movimento vertical ascendente sobre o estado do Rio Grande do Sul por vários dias. A convergência do fluxo de umidade integrada verticalmente mostrou-se como uma boa ferramenta para inferência da importância dos eventos. Os campos diagnósticos apresentados não mostram uma indicação antecipada da duração de um evento de chuva, bem como não demostram com clareza a maior frequência de elevados acumulados de chuva na metade leste do estado do Rio Grande do Sul.

30 anos da Carta Cidadã: um resgate do discurso constituinte social de Ulysses Guimarães a partir da filosofia da linguagem bakhtiniana
Authors: Teles Tayson Ribeiro
Published: May 2020

Resumo Neste artigo, por meio da filosofia da linguagem do Círculo de Bakhtin, analisa-se a fala do Deputado Federal Ulysses Guimarães no dia da promulgação da Constituição de 1988, 5 de outubro daquele ano. Enquanto presidente da Assembleia responsável por fazer a norma, coube a Ulysses, no final, a tarefa de dizer que ela estava promulgada, o que o parlamentar fez em uma histórica fala, no sentido filosófico aqui empreendido, ou “discurso”, no sentido linguístico clássico. Analisa-se essa fala, chamada aqui de “fala Ulyssiana” ou “fala promulgadora”, porque se entende que a essência da Constituição, que completou 30 anos de existência em 2018 - desde quando têm havido muitas crises políticas, instabilidades econômicas, ilegalidades e redução de direitos sociais na América Latina, necessita ser resgatada no Brasil e servir como inspiração para se prosseguir com lutas pela efetivação dos direitos. O trabalho é primordialmente filosófico, mas, valorizando a interdisciplinaridade do tema, não deixa de ser sócio-histórico, jurídico e linguístico. Os resultados evidenciam que a fala Ulyssiana é um signo ideológico que reflete os principais fatos havidos antes da feitura da Carta Cidadã, bem como demonstra parte dos entraves sociais e políticos ocorridos para que fosse erigida essa lei fundamental e, nesse sentido, seu resgate 30 anos depois é salutar para o objetivo social de alargar cada vez mais a democracia e garantir direitos sociais básicos a todos os brasileiros.
Ativismo Institucional no Poder Legislativo: confrontos políticos, assessores ativistas e frentes parlamentares
Authors: Pereira Matheus Mazzilli
Published: May 2020

Resumo A literatura sobre as relações entre movimentos sociais e Estado produzida nos últimos anos no Brasil tem destacado a interpenetração entre política institucional e extrainstitucional. Boa parte dessa literatura parte da análise das relações entre movimentos sociais e Poder Executivo, destacando, em especial, o ativismo institucional de burocratas ativistas progressistas. Nesse artigo, busco contribuir para esse debate, ao analisar o ativismo institucional no Poder Legislativo a partir do confronto político estabelecido entre ativistas progressistas do movimento LGBT e ativistas conservadores do movimento cristão familista no Congresso Nacional entre 2003 e 2014. Para essa análise, realizei entrevistas com doze assessores e parlamentares envolvidos neste confronto político. Os resultados indicam a centralidade dos “assessores ativistas” e das frentes parlamentares para o ativismo institucional e os confrontos políticos no Poder Legislativo.
Orçamento Impositivo e Relação entre Poderes no Brasil
Authors: Santos Núbia Cristina Barbosa , Gasparini Carlos Eduardo
Published: May 2020

RESUMO: Este artigo analisa o modelo orçamentário brasileiro à luz das Emendas Constitucionais nº 86, de 2015 e nº 100, de 2019 - que tornam obrigatória a execução da programação orçamentária relativa a emendas parlamentares. A proposta do trabalho é associar a discussão acerca da natureza orçamentária à questão mais ampla das relações de poder presentes no orçamento. Foi utilizada pesquisa bibliográfica e documental, com análise exploratória qualitativa, mediante a verificação comparada e argumentativa do que dispõe o ordenamento jurídico nacional, a doutrina e a jurisprudência, além de especialistas nas áreas de orçamentação e ciência política. É possível concluir que o ordenamento jurídico orçamentário nacional optou por atribuir papéis específicos aos Poderes, num sistema com responsabilidades compartilhadas. Nesse sentido, a despeito de persistir divergência na doutrina, o orçamento pátrio não teve seu modus operandi radicalmente alterado pelas Emendas, visto que a impositividade introduzida possui diversos condicionantes. Constatou-se ainda que a polêmica é relevante no tocante às relações de poder, notadamente entre Executivo e Legislativo, na disputa por protagonismo orçamentário.

Published: May 2020

ABSTRACT: The objectives of this research were to evaluate the rooting competence of mini-cuttings throughout the four seasons and to estimate the adventitious rooting time of canjerana clones. A clonal mini-garden was established with 11 clones in a closed hydroponic system. Evaluations were performed throughout the four seasons for the number of mini-cuttings produced per mini-stump, percentage of survival and rooting of mini-cuttings, number of roots, average root length, and number of rooted mini-cuttings per mini-stump. Data were submitted to analysis of variance and means were compared. A rooting curve was estimated for clones 10SM05, 12SMI25, and 12SMI43 that exhibited high competence for adventitious rooting. Our results indicated that canjerana clones can be selected for adventitious rooting competence of mini-cuttings during different seasons, and that canjerana mini-cuttings should be cultivated for 63 days in a rooting chamber.
Fuzzy modeling of volumetric efficiency and specific energy consumption in agricultural screw conveyors
Authors: Özbek Osman
Published: May 2020

ABSTRACT: Vertical screw conveyors have low energy efficiency but this is generally acceptable within the normally low power range. Previously, a fuzzy logic approach was used to model volumetric efficiency and specific energy consumption in screw conveyors. The performance of conveyors in different working conditions and the geometry of the screw were studied. It was reported that increasing the screw speed, pitch, and loading angle also increases specific energy consumption. In this study, an intelligent fuzzy model based on the Mamdani approach was developed to predict volumetric efficiency and specific energy consumption. The model inputs included the slope, speed, and pitch of screw conveyors. The fuzzy model consists of 27 rules in which three parameters, namely the goodness of fit (η), relative error (ε), and coefficient of correlation (R), are used to evaluate the model. The goodness of fit, relative error, and coefficient of correlation values were 0.986, 5.28%, and 0.99, respectively, for volumetric efficiency and 0.987, 4.93%, and 0.99, respectively, for specific energy consumption. Results revealed that the developed model is capable of predicting volumetric efficiency and specific energy consumption in barley transport under different working conditions with high accuracy.

ABSTRACT: Essential oils are possible alternatives to the use of synthetic pesticides for control of fungal contamination. Ginger (Zingiber officinale) essential oil (GEO) is known for having antifungal and antiaflatoxigenic properties, but its use as a fumigant in situ has not been studied yet. The aim of this study was to evaluate GEO’s effects upon Aspergillus flavus as a fumigant agent in stored maize grains. The main compounds reported in GEO were α-zingiberene (23.85%) and geranial (14.16%), characterized by gas chromatography-mass spectrometry and nuclear magnetic resonance. The GEO was used as a fumigant in irradiated maize grains in concentrations ranging from 5 to 50 µg/g and the resulting effects were compared to a synthetic antifungal agent (carbendazim and thiram), an antifungal traditionally used for seed treatment. The antifungal efficacy of GEO against A. flavus has been proven in a dose-dependent manner through in situ (maize grains) test. The GEO inhibited aflatoxin production at concentrations 25 and 50 µg/g and controlled fungal growth. Therefore, GEO can be used as an effective and non-toxic alternative to conventional treatments in stored maize grains for the natural control of A. flavus.

Published: May 2020

ABSTRACT: The present study aimed to identify the elements of the Theory of Planned Behaviour along with health consciousness and determine the role of knowledge as a moderating variable in Pakistan and Malaysia. Three hundred and forty-one observations from Pakistan and 280 observations from Malaysia were acquired through questionnaire; while, confirmatory factor analysis and structural equation modelling was applied for the analysis. The magnitude of the results varied across both countries; however, attitude, subjective norms and health consciousness, as well as their interaction terms, were significant predictors, whereas, perceived behavioural control and its knowledge interaction terms had insignificant impacts on the purchase intentions of consumers for both countries. This research will help to further understand about consumer perception in the purchase of organic food items, which will assist retailers, advertisers and manufacturers in developing strategies for such products.

ABSTRACT: Although Northeast Brazil is considered free of foot and mouth disease (FMD) with vaccination, several economic and health damages are still recorded due to the occurrence of vesicular syndromes that can be evaluated, such as Vesicular Stomatitis (VS). Therefore, this study aimed to confirm the occurrence of this disease and to determine the predominant viral serotype in suspected cases notified to the Official Veterinary Service of Ceará in 2013 performing official diagnostic protocols recommended by the World Organization for Animal Health. After clinical and epidemiological investigation in 46 farms, 32 probable cases of VS were considered with 78 sampled animals, 65 bovines and 13 equines. Serum (54) and epithelium (24) samples were collected. Six (14.6%) of 41 bovines and 8 (61.5%) of 13 equines described seroconversion to Indiana Vesiculovirus (IVV) by viral neutralization. The IVV was detected in 15 (62.5%) of 24 bovines epithelia using the indirect sandwich ELISA. Finally, positive epithelium underwent complement fixation test viral subtyping that identified the occurrence of Indiana III serotype (Alagoas/IVV-3) in 11 (73.3%) of 15 previous positives cattle. These were the first confirmed cases of VS in Ceará with an official diagnosis of IVV-3, confirming the endemic character attributed to the state through previous unofficial serological surveys. The presence of VS is a continuing diagnostic challenge, given the risk of possible incursions of FMD. Vesicular stomatitis is recurrent and is a worrying in this area free of foot and mouth disease with vaccination that bring damage to producers and a maximum alert to the Sanitary Defense Organs in the face of a probable case of vesicular syndrome.

Published: May 2020

ABSTRACT: The objective of this research was to evaluate the effect of seeder furrow opening mechanisms on soil physical characteristics, plant growth, and soybean yield in lowland areas with the presence of compacted layer near the surface. An experiment was conducted in the lowland experimental area of the Federal University of Santa Maria-RS, Brazil, during the 2015/16 and 2016/17 growing season. The experimental design was a randomized block with five replications and four treatments: Planter using shank (S) at 0.23 m depth; S at 0.13 m; Planter using double disk at 0.07 m depth and Raised-bed + S at 0.12 m depth. The use of S at 0.23 m depth allowed reduction of penetration resistance and increase of soil macroporosity in the layers 0-0.1 and 0.1-0.2 m depth in the seeding row. Sowing with S at 0.23 m depth and Raised-bed + S at 0.12 m depth allowed a better development of soybean plants in compacted irrigated rice area (higher nodulation, leaf area index and root growth), as well as higher grain yield.

ABSTRACT: The effects of energetic supplementation and mixture vetch (Vica sativa L.) were studied to evaluate the intramuscular fatty acid profile of steers finished on oat (Avena sativa L.) pastures. Eighteen 21-month-old crossbred steers were evaluated. The experiment was carried out in three treatments and six repetitions: oat pasture (OA), oat pasture + vetch (OA + VET), and oat pasture + supplementation (OA + SUP). Supplementation comprised the addition of corn meal at a daily dose of 1% of the animals’ body weight. Steers receiving supplementation had higher lipid content in Longissimus lumborum than did those fed with OA + VET (1.25 vs 1.02%), whereas those fed with OA (1.15%) showed intermediate values. Conjugated linoleic acid levels were higher in steers fed OA (0.57%) and OA + SUP (0.59%), whereas the highest amount of omega-3 fatty acids was observed in animals fed OA + VET (3.32%). Pasture-finishing without supplementation resulted in a lower ratio of n-6:n-3 (3.14). Steers finished in oat mixture with vetch showed healthier intramuscular fat than did those finished with cornmeal supplementation; importantly, the higher the amount of PUFAs, the better n-6:n-3 ratio.

Abstract: The dynamics of the interaction between different levels in production system is the study of many research groups to seek a better understanding of the complex nature of such systems to propose an effective and efficiency from rational use of available resources and required inputs. Demand for products increasingly customized by a dynamic and competitive market has reduced considerably the life cycle of such products and flexibility of production processes has become essential for companies. Flexibility is not only one attribute, but a set of attributes that provides the flexibility for production systems. The interactions between the flexible sub-systems are sources of waste and rework, causing high costs in the production process. In this sense, the concept of Lean Manufacturing has promoted a restructuring of some processes of the MES (Manufacturing Execution Systems), responsible for managing the activities of production, integrate data from the ERP (Enterprise Resource Planning) and synchronize production tasks the flow of materials, making them oriented by the demand. One other important aspect in the industrial context is the new future vision promoted by Industry 4.0 paradigm that is envisioned a complete decentralization of control of the production system by autonomous and intelligent devices interconnected by a communication system, that contribute to the global goals of the enterprise. The ANSI/ISA S95 presents a conceptual model that may contribute to the implementation of the industry 4.0 concept. The objective of this study is to present a proposal for modeling of objects in level 3 of the S95 standard using interpreted Petri nets.

Published: May 2020

ABSTRACT The development of Andean common bean lines that contain high macromineral concentration and a phenolic compound concentration that meets the consumer’s dietary requirements is unprecedented in the literature. The objectives of this study were to obtain estimates of phenotypic parameters for the macromineral and phenolic compound concentrations in a recombinant inbred line (RIL) population of Andean beans and to select lines with nutritional and functional properties. The RIL was obtained from a cross between cultivars Hooter and Cal 96. The lines in the F5:6 and F5:7 generations and the cultivars were evaluated in two consecutive experiments in the same experimental area. The concentrations of potassium (K), phosphorus (P), magnesium (Mg), and calcium (Ca) were determined by acid digestion, whereas the phenolic compound concentration was obtained by the Follin-Ciocalteu method. A significant genotype effect was observed for all traits evaluated in the F5:6 and F5:7 generations. Intermediate-to-high heritability estimates (h2: 43.15 to 98.85%) were obtained for the concentrations of K, P, Mg, Ca and phenolic compounds. These traits exhibited transgressive segregation and quantitative inheritance in the RIL population of Andean beans. Lines DFA 34-18 and DFA 46-18 have high K and P concentrations and low phenolic compound concentration and will be selected by the human nutrition. Lines DFA 04-18 and DFA 05-18 and cultivars Pérola, IPR Siriri, IAC Imperador, and IPR Tangará showed high concentrations of two or more macrominerals and phenolic compounds; therefore, they have nutritional and functional properties and will be selected by the breeding program.

ABSTRACT The use of an appropriate method that accurately expresses physiological seed quality and minimizes possible phytotoxicity by chemical products in laboratory testing with soybean seeds is relevant. The objective of this work was to evaluate the influence and infer the method adequacy for the representative evaluation of physiological quality of soybean seeds treated with phytosanitary products. Two experiments were carried out in a completely randomized design, with trial 1 in a 9×5 factorial scheme involving nine seed treatments, including fungicides and insecticides, and solutions with five osmotic potentials (0, -0.25, -0.5, -0.75 and -1.0 MPa) for wetting a paper substrate in a germination experiment, with evaluation of the normal seedlings at five and eight days after sowing. The second experiment consisted of a 9×7 factorial, with nine seed treatments and seven methods for germination evaluation at 5 days (between paper - BP, between sand - BS, between paper with water restriction - BPWR, between paper with preconditioning - BPC, sand between paper - SBP and vermiculite between paper - VBP). Treatments with insecticides affect seedling germination and evaluation, with greater phytotoxicity in relation to fungicides. Methods with readily available water led to greater phytotoxicity than methods with low water availability. For soybean germination evaluation of seeds treated with phytosanitary products, the BPC, SBP and VBP methods were optimal.

Authors: Nascimento Francisca Caroline Lopes do , Rodrigues Maria Cristina Soares
Published: May 2020

Objective: to validate the Risk Assessment Scale for the Development of Injuries due to Surgical Positioning in the stratification of risk for injury development in perioperative patients at a rehabilitation hospital. Method: analytical, longitudinal and quantitative study. An instrument and the scale were used in the three perioperative phases in 106 patients. The data were analyzed using descriptive and inferential statistics. Results: most patients showed high risk for perioperative injuries, both in the scale score with estimated time and in the real-time score, with a mean of 19.97 (±3.02) and 19.96 (±3.12), respectively. Most participants did not show skin lesions (87.8%) or pain (92.5%). Inferential analysis enabled us to assert that the scale scores are associated with the appearance of injuries resulting from positioning, therefore, it can adequately predict that low-risk patients are unlikely to have injuries and those at high risk are more likely to develop injuries. Conclusion: the scale validation is shown by the association of scores with the appearance of injuries, therefore, it is a valid and useful tool, and it can guide the clinical practice of perioperative nurses in rehabilitation hospitals in order to reduce risk for injuries due to surgical positioning.

Abstract Objective: To verify factors associated with early newborn access to biological neonatal screening. Method: A cross-sectional quantitative study was carried out with all newborns who underwent tests in healthcare units, hospitals, and laboratories of a city in the state of São Paulo, Brazil, with programs linking healthcare information. The following variables were investigated: child’s age at collection (dependent); place of collection; date of collection; and type of user (independent). Descriptive and inferential statistics were applied. Results: Records of 15,652 screenings were found in the two years analyzed. In the first year analyzed, 7,955 births and 7,640 (96.0%) tests were recorded, of which 5,586 (73.1%) were undertaken with newborns between three and five days old. In the next year analyzed, 8,316 births and 8,012 (96.3%) screenings were recorded, of which 7,025 (87.6%) were undertaken with newborns in the same age group. A statistically significant association was found between the variables “child’s age” and “type of user” in one year, and between the variables “child’s age” and “place of collection” in both years. Conclusion: Early access to these tests enables the screening of diseases and referral for treatment. The present study contributes to the management of child care programs by presenting strategies linking data and actions to improve access to biological neonatal screening.

Abstract Objective: to discuss the paths taken by Brazilian Nursing in the development of terminological subsets of the International Classification for Nursing Practice. Method: documentary research, carried out in master’s dissertations and doctoral theses, which developed terminological subsets, available at the Bank of Doctoral Theses and Master’s Dissertations of the Under-graduation Personnel Improvement Coordination. The variables were analyzed were institution, year; academic level, type of health service, methodological approach, clientele, theoretical reference, validation of terms, cross mapping, modeling of new concepts, validation of statements, method used for elaboration, term collection, finalization and dissemination. Results: 124 doctoral theses and master’s dissertations were found, 91 were excluded and 33 were included, 23 (69.70%) of which were master’s dissertations, with the highest production in 2014 (n=10; 30.30%), with emphasis on the Northeast (36.36%); the ‘Primary Care’ scenario, with six studies (18.18%); and the predominant clientele was cancer patients. As for the methodological characteristics, in 96% of the studies, the quantitative approach was used; in 2%, a qualitative approach; and 2% associated the quantitative and qualitative approaches. As for the type of study, 60% were methodological and 24% descriptive-exploratory, with the Horta model being the most used (36%). Conclusion: the paths are successful, yet still permeated by weaknesses in the validations and potentialities to standardize the language.

Abstract Objective: to analyze the intensity of nursing work in public hospitals. Method: cross-sectional, quantitative study, carried out in 22 public hospitals. The sample was composed of 265 nurses and 810 nursing technicians and assistants. Data were collected through a questionnaire and analyzed with Exploratory Factor Analysis. The calculation of the distribution of the work intensity by category was done using a score ranging from -1 to +1 standard deviation of the data. Fisher’s exact test (0.05 <p≤0.10) was used to observe the significance between groups according to the employment bond. Results: work intensity contributed to the explanation of precarization of work, with a value of 13% for nurses and 51.2% for technicians and assistants. For the technicians and assistants, the variables with the highest factor loadings were ‘work requires more than she can do’ (0.6696) and ‘takes on multiple tasks due to staff shortages’ (0.6156). Among nurses, the highest factor loadings were observed in the variables ‘time pressure at work (0.6779) and ‘Work pace’ (0.6651). Conclusion: the variables analyzed indicate that work intensity occurs differently among nursing workers, and is revealed by the versatility, understaffing and flexibility of work.

Abstract Objective: to identify, from the nurse perspective, situations that interfere with the availability of beds in the intensive care unit in the context of hospitalization by court order. Method: qualitative exploratory, analytical research carried out with 42 nurses working in adult intensive care. The selection took place by non-probabilistic snowball sampling. Data collected by interview and analyzed using the Discursive Textual Analysis technique. Results: three categories were analyzed, entitled deficiency of physical structure and human resources; Lack of clear policies and criteria for patient admission and inadequate discharge from the intensive care unit. In situations of hospitalization by court order, there is a change in the criteria for the allocation of intensive care beds, due to the credibility of professionals, threats of medico-legal processes by family members and judicial imposition on institutions and health professionals. Conclusion: nurses defend the needs of the patients, too, with actions that can positively impact the availability of intensive care beds and adequate care infrastructure.
