Helicoverpa armigera (Hübner, 1805) (Lepidoptera: Noctuidae) is a cosmopolitan pest with wide geographical distribution in Brazil. This pest was officially registered in 2013 on cotton, soybean, corn, and some weeds, although this species may have been present in the country since 2008. The objective of this work was to evaluate the efficiency of eight insecticides (seven chemicals and a biological product) to control small and large H. armigera caterpillars. The experiment was conducted under laboratory conditions (T 22±1 °C; RH 70±10%; 12h photoperiod), with nine treatments (g a.i./ha dose): flubendiamide (72), chlorantraniliprole + lambda-cyhalothrin (30 + 15), chlorfenapyr (288), spinetoran (18), indoxacarb (120), emamectin benzoate (10), metomil (322.5), Bacillus thuringiensis (500), and control (water). A completely randomized design was used with four replications for each size of caterpillars (small and large), and each repetition (plot) consisted of five H. armigera caterpillars fed with bean leaves immersed in the different treatments evaluated. The larval mortality evaluations were performed at one, three, five, and seven days after contact with the treated bean leaves, determining the control efficiency (E%) through the formula of Abbott (1925). All chemical and biological treatments tested caused significant mortality of small and large H. armigera caterpillars, reaching a control percentage of 100% at seven days after treatment, demonstrating the possibility of using the insecticides tested to control this pest under field conditions.

Genotype-by-environment interaction analysis is vital for cultivar release, and to identify suitable crop production sites. The current study aimed to determine sorghum grain yield stability and adaptability and to identify the most informative and representative environments for sorghum grain yield performance in Uganda. Sorghum grain yield data of eight (08) genotypes; ICSR 160, IS8193, IESV92043DL, IESV92172DL, GE17/1/2013A, GE35/1/2013A, SESO1, and SESO3 tested across eight (08) major sorghum production area in Uganda for two consecutive seasons of 2017 using randomised complete block design with 2 replications were analysed via Additive Main effects and Multiplicative Interaction (AMMI) and Genotype Main Effect and Genotype by Environment interaction effects (GGE) using PB tools. Genotype IESV92043DL was the ideal genotype in the entire test environments with mean grain yield of 2783 kg ha-1 however genotype ICSR 160 had the highest grain yield of 2823 kg ha-1 across all the test environment. On the other hand, GE17/1/2013A was the most stable and adapted genotype across all the test environment. Of the eight (08) environments tested, biplot analysis precisely grouped the test environments into two presumed mega-environments with the best genotype being IS8193 and ICSR 160. Out of eight (08) trial sites, two (02) environments; Abi and Mayuge were the most representative and informative environment for sorghum grain yield performance in Uganda.
Characterizing the Distribution of Ppm Gluten in Gluten Free Oatmeal Servings Contaminated with a Barley Kernel
Authors: Fritz Ronald D. , Chen Yumin
Published: May 2020

Oats are regularly contaminated with gluten-containing grains like wheat, barley and rye. For producers of gluten free oatmeal, contamination potential makes it prudent to understand the consequences in terms of gluten dosing, as labeling requirements specify a gluten maximum. To do this, statistical simulation has been used to produce virtual oat servings (40g) contaminated with either two row or six row spring barley. The results are probability distributions for ‘actual’ ppm gluten (free of measurement influences) and ‘as measured’ via R5 ELISA. Findings show ‘actual’ ppm gluten to be normally distributed with 57 ppm and 41 ppm gluten averages with 14 and 12 ppm standard deviations (stdevs) for two and six row barley, respectively. ‘As measured’ ppm gluten results are lognormally distributed with 61 and 44 ppm gluten averages with 63 and 47 stdevs for two and six row barley, respectively, employing an 80% analytical recovery rate and a multiplier of 1. These analyses show that ‘as measured’ results possess false negative probabilities (relative to a < 20 ppm gluten regulatory requirement) from 0.14 to 0.34 depending on recovery rate and barley type. This work highlights the need for non-homogenous grinding issues to be addressed in whole grain gluten assessment, for analytical recovery rates to be defined for gliadin in oats, and for appropriate conversion factors to be determined in order to attain capable measurement of gluten in oats due to barley kernel contamination.

Published: May 2020

Migration of styrene monomer from expanded polystyrene (EPS) at various time intervals (3 hr, 1, 2, 3, 5, 7, 9, 12, 18 days at 51OC) into nine different stimulants (water, 8% ethanol in water, 3% acetic acid, and 3 and 10% of food-grade citric, malic and tartaric acid) was determined using a modified FDA migration cell. Exposure to 8% ethanol resulted in the greatest average migration of styrene (147.6 µg/L) during 18 days of storage compared to all other stimulants tested. The concentration for styrene in 8% ethanol ranged from 49.3 to 228.5 µg/L over all exposure times. For all stimulants tested, styrene concentrations were greater than or equal to 22 µg/L after 3 hours of exposure. EPS exposed to malic (3 and 10%) and 10% tartaric acids had greater styrene migration than styrene exposed to all other acidic stimulants tested.

Authors: Raymond Jennifer K. , Onyango Arnold N. , Onyango Christine A.
Published: May 2020

The Kenyan government is promoting fish farming to boost fish supply and reduce rural poverty and malnutrition. This study was carried out to determine the differences between the chemical composition of wild and farmed fish particularly Nile tilapia (Oreochromis niloticus) and African Catfish (Claris gariepinus) species. Wild fish were obtained from City market Nairobi, while farmed fish were obtained from selected ponds in Sagana and Kamulu (Kenya). Proximate composition, mineral and heavy metal content of the fish were determined using standard methods of analysis. Farmed fish contained significantly higher moisture content than the wild fish. Protein content in wild fish ranged from 21.9 – 22.1 % compared to 16.0 – 19.2 % in farmed fish. Fat content in wild fish ranged from 3.0 – 3.8 % compared to 1.9 – 4.8 % in farmed fish and ash from 1.8 – 2.1 % in wild compared to 1.1 – 1.5 % in farmed fish. The concentration of minerals in wild fish ranged from 2.8 – 3.0 mg/100g of iron, 5.5 – 5.6 mg/100g zinc, and 39.9 – 43.8 mg/100g calcium compared to the lower values of 1.9 – 2.4 mg/100g of iron, 28.2 – 37.0 mg/100g calcium and 4.3 – 5.0 mg/100g zinc in farmed fish respectively. Unfortunately, the wild fish was found to contain significantly higher concentrations of heavy metals as compared to the farmed fish (P < 0.05). From the results, it was evident that wild fish were nutritionally superior to the farmed fish but, they also contained significantly higher levels of toxic heavy metals.

Published: May 2020

Flow-mixing is common in technological processes, and both ejectors and turbofans can produce an interaction between flows with different energy potentials. Ejectors have been extensively used, and their analytical models have been widely presented. To the best of the authors’ knowledge, there is a lack of studies exploring the efficiencies of turbofans. The goal of this paper is to compare thermodynamic processes in these devices. Their efficiencies are compared in terms of compression and entrainment ratios. A comprehensive one-dimensional subsonic thermodynamic models of the ejector and turbofan are presented. The quantitative indices are obtained for the same initial conditions expressed as the ratio of differences in enthalpies for ideal compression and ideal expansion. When initial conditions are equal to the numeric value of the combination of the isentropic efficiency of the evaluated components (numerical case 0.16), both devices have the same efficiencies; at lower initial conditions (numerical case 0.10), a turbofan’s entrainment ratio is 1.5 times and compression efficiency 1.25 times higher; at higher values of initial conditions (numerical case 0.28), the ejector is more efficient. Such distinctive characteristics of turbofans and the nature of their variation may correspond to the specific application areas of technological equipment that require certain flow-mixing parameters.

Published: May 2020

This paper investigates the screening characteristics of the multi-layer vibrating screens. A portable linear screen with a three-layer screen mesh and the vibrating screening experimental platform were designed and simulated. Based on the discrete element method (DEM), the influences of the motor excitation frequency, the pulverized coal mass flow rate, and the shape of the particles on the screening accuracy of each layer of the screen and the total energy contained in the particles were analysed. The simulation analysis found that, during the vibration screening process, with the increase of the frequency of motor excitation, the screening accuracy of each screen layers increased first and then decreased. The ratio of the sieving accuracy of the first screen and the third screen is reduced first and then increased. The energy contained in the particles gradually increases. With the increased pulverized coal mass flow rate, the screening accuracy of each layer gradually decreased, while the ratio of the screening accuracy of the first layer to that of the third layer gradually increased. The energy contained in the particles gradually decreases. Similarly, the increased percentage of non-spherical particles generated slightly decreased screening accuracy and an increased ratio of the screening accuracy of the first and third screens. The particles also contain much less energy than spherical particles do. A simulation was carried out on the vibrating screening experimental platform with screening materials such as soybeans and red beans. The experimental results matched the discrete element simulation. The screening accuracy was proved to be higher when the excitation frequency lay in 18 Hz to 20 Hz, and the particles mass flow rate stayed below 0.4 kg/s. This study demonstrated that changing the shape of particles is a practical way of managing real screening work. It also provided a theoretical basis and reference for the design and applications of multi-layer vibrating screens.
Specialist counselling in the social work with a person and a family after a traumatic experience
Authors: Weissbrot-Koziarska Anna
Published: May 2020

Times we live in make us question what is going to happen with the world after the pandemic. The struggle against COVID-19 and changes produced will have impact on the mind of many people. Some lose their relatives, who they cannot bury. Others live in a constant state of fear about their health and future living. The world will never be the same. People will never be as they were before this traumatic event. The invisible enemy – coronavirus – will leave a lasting mark on their memory. Many will need support which can be provided by specialist counselling. Many will struggle with a trauma, which will make the return to “normality” impossible for a long time.
A traumatic experience is a psychological trauma suffered by a person and caused by a strong, sudden stimulus. This stimulus is intensive enough to cause changes in the areas of soma, psyche and polis, and it also directly threatens health or life of a person. People after a traumatic experience require a complex assistance to return to their normal functioning. Currently, this stimulus is a deadly virus. The article presents the role of the specialist counselling in the area of social work with a person and their family after a traumatic experience.

A Importância do Pensamento Crítico em Inovações Curriculares: interface com a educação sexual emancipatória
Authors: Yared Yalin Brizola , Melo Sonia Maria Martins de , Vieira Rui Marques
Published: May 2020

A partir de uma pesquisa de doutoramento no campo da Educação em interface com a sexualidade, o presente artigo discorre sobre a importância da promoção do Pensamento Crítico (PC) em mudanças paradigmáticas curriculares no ensino superior. O lócus do estudo foi um Curso de Graduação em Medicina organizado em currículo integrado, orientado por competências, com quadro docente interdisciplinar e multiprofissional, e desenvolvido por metodologias ativas. Objetivamos, neste ensaio, problematizar o desenvolvimento do PC como elemento substancial na materialização de uma proposta curricular que visa uma transformação paradigmática educacional. Norteado pelo paradigma do materialismo histórico dialético, o ensaio configura-se como um estudo de caso que utiliza o método dialético para análise da realidade. Os instrumentos de coleta compreenderam o uso de questionário e, posteriormente, a entrevista semiestruturada áudio gravada. Para análise, foi utilizada a análise de conteúdo, com complementos da análise textual discursiva. Como resultado, registrou-se que o desenvolvimento intencional do PC é fundamental para a busca de uma transformação paradigmática educacional efetiva. Embora hoje sejam defendidos e divulgados vários elementos inovadores no processo de ensino e de aprendizagem, muitos docentes do ensino superior continuam agindo amparados no paradigma convencional acriticamente. Isso sugere que as práticas não promovem naturalmente o PC.
O desafio político da educação escolar: desdobramentos para pensar a Formação Inicial em Educação Física
Authors: Bagnara Ivan Carlos , Fensterseifer Paulo Evaldo
Published: May 2020

A Formação Inicial (FI) em Educação Física (EF) tem sido foco de análises nos últimos anos, pois se constitui em tempo e espaço destinado à formação dos professores responsáveis por desenvolver a EF na escola sob o prisma de um componente curricular e não mais na perspectiva de “atividade”. Pensar a Educação Física Escolar (EFE) sob esse novo estatuto significa estruturar a ação docente conectada aos sentidos e responsabilidades da escola, o que pressupõe avaliar retrospectivamente o processo formativo desenvolvido. Nesse sentido, neste estudo, objetiva-se analisar as concepções que os professores que atuam na FI em nível de Licenciatura em EF possuem acerca das responsabilidades sociais da escola. Para isso, foi realizada uma pesquisa colaborativa, na perspectiva qualitativa, da qual participaram doze docentes que atuam na FI em EF. Os dados foram produzidos através de anotações em diário de campo e elaboração de narrativas docentes. Os resultados indicam haver heterogeneidade na compreensão acerca das responsabilidades sociais da escola, as quais foram divididas em quatro categorias: conhecimento de qualidade; responsabilidade social; necessidades e demandas sociais; valores morais. A impressão que se tem é que as concepções referentes às responsabilidades da escola, no contexto do estudo, além de heterogêneas, carecem de uma fundamentação teórica sistematizada, revelando um caráter fragmentário. Isso retrata certa “orfandade política” entre os professores da FI, e como na política não tem vácuo, a ausência de uma consciência republicana deixa margem para proposições subjetivas, as quais contribuem para manter a EFE numa condição de menoridade.
Avaliação da educação infantil: um subcampo social em disputa
Authors: Nagase Raquel Hissae , Limana Amir , Azevedo Mário Luiz Neves de
Published: May 2020

O objetivo deste artigo é analisar a avaliação da educação infantil, com base nas perspectivas indicadas por Souza (2014): uma com ênfase nas condições de oferta e outra com foco no desempenho dos alunos. Inicialmente, são apresentados alguns conceitos que fundamentam a análise, cuja base se encontra na teoria de campo, de Pierre Bourdieu, e na tese de Agenda Globalmente Estruturada para a Educação (AGEE), de Roger Dale. Tratar sobre esses conceitos contribui para compreender a importância que a avaliação da educação passa a ter no contexto de reestruturação do Estado, bem como a preocupação da implementação de uma avaliação da primeira etapa da educação com caráter gerencialista. Posteriormente, o objetivo é apontar alguns retrocessos envolvendo a educação infantil que, de certo modo, convergem com uma das perspectivas propostas. Ao mostrar o debate sobre a avaliação dessa etapa, percebe-se que a avaliação da educação infantil é um objeto em disputa no campo educacional, mas também é um subcampo em que instrumentos, metodologias e resultados estão em disputa.

Published: May 2020

Este artigo é parte de pesquisa desenvolvida como dissertação de mestrado e tem por objetivo analisar as formas de acompanhamento desenvolvidas pelas famílias à escolarização dos/as filhos/as que frequentam os sexto e sétimo anos em escolas privadas. O estudo, de abordagem qualitativa, contou com a participação de dez mães cujos filhos e filhas estudam em cinco escolas diferentes em Porto Velho – RO. Os dados foram produzidos por meio de entrevistas semiestruturadas e analisados considerando-se o contexto socioeconômico, a constituição das famílias e a etapa da escolarização em que estão os/as estudantes. Os resultados indicam que as mães são as principais responsáveis pelo atendimento às necessidades de escolarização dos/as filhos/as e desenvolvem diferentes ações de acompanhamento as quais foram organizadas em três categorias: ações em casa (ações com o auxílio dos pais e ações nas semanas de provas); ações junto à escola e ações de terceirização. Conclui-se que o cuidado com a escolarização dos filhos e filhas é predominantemente feminino nas famílias pesquisadas, embora sejam mulheres economicamente ativas. A alta escolaridade das famílias, a valorização social da escola e o acompanhamento próximo são fatores que contribuem para o sucesso escolar nesse contexto.

O artigo de natureza bibliográfica e documental tem como objetivo analisar uma experiência de gestão democrática na escola pública estadual Zandoná em Barra Funda, Rio Grande do Sul. Essa escola vem construindo, desde 2001, uma gestão democrática de alta intensidade, envolvendo a comunidade escolar e organizações da sociedade civil, especialmente movimentos sociais. Boaventura de Sousa Santos, entre outros autores, vem chamando atenção para a necessidade de dar visibilidade às práticas democráticas em construção que conseguem superar compreensões de democracia como mero procedimento formal. Com base em produções bibliográficas sobre democracia e gestão democrática e em documentos e publicações da escola, serão analisadas algumas dimensões dessa experiência, os seus avanços e os desafios enfrentados. Para tanto, inicia-se com uma problematização mais geral do tema, segue-se com uma discussão sobre as potencialidades políticas e pedagógicas da gestão democrática e adentra-se a experiência da escola. As considerações finais reafirmam a tese de que essa experiência se constitui efetivamente numa democracia de alta intensidade e contém potencialidades para superar muitos dos problemas existentes na escola.

Studies on the waste of school meals has been reason for several investigations, considering that this might reflect in the planning, production process, distribution and nutritional adequacy of the menu offered to schools. Thus, the aim of the present study was to evaluate food waste through the acceptance and the school feeding membership served in three public schools of elementary school II of municipal school system, located in the city of Itapetinga - BA. In this study we used meals served to 720 (seven hundred and twenty) students of both sexes and aged 10 to 17 years old, collected in two periods of the school lunch distribution (morning and afternoon snacks). Were evaluated thirty (30) meals per shift (60 students daily), totaling 240 meals served per school. Semi-structured questionnaires were used for the students. It was found that the acceptability of school meals was less than 85% limit established by brazilian law and that the school meals was not well accepted by the students, based on their preferences. ost of the students even enjoying the food preparations served in schools, does not have the custom of repeating the meal and rated as ideal attributes on the acceptance of meals (seasoning, served temperature and quantity). The three analyzed schools, two indices showed good adhesion (exceeding 80%) and only one was found to be low, adhesion index. Therefore, it is suggested to carry out studies exploring the correlation of factors such as the amount of power produced at school, age and sex.

A construção civil gera uma grande quantidade de resíduos e, consequentemente, enfrenta problemas no destino final desses materiais. Entre os materiais mais comuns, podemos destacar o concreto como o segundo maior gerador de resíduos, sendo, portanto, um problema para a sociedade. Nesse contexto, esta pesquisa analisou o uso de resíduos de blocos de concreto como agregados no bloco estrutural do edifício. Para isso, foram moldados blocos estruturais de concreto com diferentes conteúdos de resíduos reciclados e posteriormente submetidos a testes de resistência à compressão, absorção de água e análise dimensional. Os resultados mostraram que a adição de resíduos reciclados causou um aumento na absorção de água e uma redução na resistência à compressão, pois o agregado convencional foi substituído pelo agregado reciclado. Concluiu-se que os resíduos de concreto podem ser aplicados como um agregado de bloco de concreto estrutural, desde que respeite certos limites do teor de resíduos. A aplicação da técnica pode consumir todo o resíduo proveniente da fabricação de blocos de concreto estruturais.

The work studies biodigestors, cisterns and desalinizers as sustainable alternatives to coexist with the semi-arid region, seeking to understand how it is possible to benefit rural populations from the production and use of social technologies. The methodology consists of bibliographical surveys from case studies and field studies on the use of these technologies in the semi-arid region. Experiences of use were selected in the municipalities of Barreira, Ocara, Redenção and Ibaretama in the state of Ceará. In the biodigestor is contextualized the most used models at Brazil and the semiarid, with emphasis on the models adopted in the municipalities of Barreira, Ocara and Redenção. In addition, to address the importance of the use of biogas and biofertilizer. In the cisterns, the types that were used in the semi-arid region were verified and the experience of the tanks program in the municipality of Ibaretama was mentioned. In the case of desalinators, the relevance of desalination systems for populations living in water scarcity was discussed, identifying the current equipment panorama installed in Barreira. As results, it was observed that it appears as a solution to meet the basic needs of populations with water supply. Biogas can be used to replace cooking gas and biofertilizer as fertilizer for plants. To do so, it requires greater attention from the public power and active involvement of the population. It is concluded that these technologies are feasible, adaptable to rural property, simple and low cost, since they tend to solve social and structural problems, besides generating income and quality of life for the populations.
