Abstract The objective of this study is to describe the agronomic attributes of the SCS443 Isadora apple tree cultivar and to highlight its potential use in Brazil. Obtained by the hybridization made at Epagri in 2001 between ‘Imperatriz’ and ‘Cripps Pink’, after 20 years of agronomic evaluations carried out in Caçador-SC and Fraiburgo-SC, ‘SCS443 Isadora’ was originated. This cultivar has a wide plasticity of adaptation to the southern Brazilian climate due to the medium chilling requirement to overcome dormancy. It has greater resistance to the main apple diseases than cv. Gala and fruit harvest is later than cv. Fuji. Its apples have a red skin and firm flesh (=18 lb), with high sugar content (= 14.5 %) and very crunchy and juicy texture, as well as high storage ability in post-harvesting. ‘SCS443 Isadora’ apples can be stored for 8 months, even in refrigerated air atmosphere chambers (21% O2) with inhibition of the ethylene response by the use of 1-methylcyclopropene (1-MCP). Even stored for long periods of time, the indices of quality loss, physiological disorders and fruit rotting in ‘SCS443 Isadora’ apples are lower than on Gala and Fuji apples.

Resumo O trabalho tem como objetivo descrever os atributos agronômicos da cultivar de macieira SCS443 Isadora e evidenciar suas potencialidades de uso no Brasil. Obtida pela hibridação realizada na Epagri, em 2001, entre ‘Imperatriz’ e ‘Cripps Pink’, após 20 anos de avaliações agronômicas realizadas em Caçador-SC e Fraiburgo-SC, originou-se a ‘SCS443 Isadora’. Esta cultivar é de ampla plasticidade de adaptação ao clima sul-brasileiro, em função do médio requerimento de frio hibernal, para superação da dormência das gemas. Possui maior resistência às principais doenças da macieira que a cv. Gala, e a maturação dos frutos é mais tardia que da cv. Fuji. As suas maçãs são de epiderme vermelha e de polpa firme (=18 lb.),com alto teor de açúcares (= 14,5 %) e de textura muito crocante e suculenta, bem como de muito alta capacidade de conservação em câmara fria. Maçãs ‘SCS443 Isadora’podem ser armazenadas por 8 meses, mesmo em câmaras de atmosfera do ar refrigerado (21% de O2), com a inibição da resposta ao etileno pelo uso do 1-methylcyclopropene(1-MCP). Mesmo armazenadas por longos períodos de tempo, os índices de perda de qualidade, dedistúrbios fisiológicos e de podridões são inferiores aos das maçãs Gala e Fuji.

Abstract Propolis is a resinous product collected by honeybees with a complex chemical composition. Sodium carboxymethylcellulose is a polymer commonly used in wound care. The goal of the present work was to produce and characterize NaCMC membranes loaded with extract of Brazilian brown propolis (CMC-P). Flavonoids and phenolic acids were identified in the propolis extracts, where the main identified substance was kaempferide. The brown propolis extracted was active against S. aureus. The low swelling capacity and high gel fraction of CMC-P would be the consequence of propolis (responsible for a hydrophobic barrier) filling the pores of the membrane. Propolis could be anchoring the NaCMC chains (as observed by FTIR) due to interaction between components, which is corroborated by the CMC-P sample degrading less than the CMC sample (>400ºC). There was non-linear diffusion release kinetics for most phenolic substances of the propolis extract. The CMC-P sample presents potential as a dressing material.

NaCMC is a biocompatible polymer that can be crosslinked with citric acid to form a gel matrix. Melaleuca oils have antimicrobial and anti-inflammatory properties with potential for wound healing. The goal of this work was to investigate the characteristics of NaCMC-Melaleuca oils gels. The gels were characterized by FTIR, TGA, mechanical analysis, and in vitro swelling and S. aureus inhibition tests. The oils were characterized using chromatography, presenting high values of (1,8-cineol/terpinen-4-ol), and evaluated for confirmation of their effect against S. aureus. The samples showed physical interactions between NaCMC, citric acid and the Melaleuca oils. Erosion in saline solution was higher in the gels with oils, attributable to interference with crosslinking. The membranes presented high contribution of relaxation mechanism and low contribution of Fickian diffusion regarding the swelling ability. The presence of the oils increased thermal stability and diminished gel fraction and mechanical properties, indicating that the oils interact with the matrix anchoring the chains. Although melaleuca oils themselves were active against S. aureus and CA was responsible for the NaCMC hydrogels activity, the incorporation of melaleuca oils in NaCMC gels was not reported previously. This report indicates that NaCMC hydrogel may be a proper matrix for essential oils incorporation.

Resumo Nesse estudo apresentam-se os resultados obtidos de uma pesquisa realizada com professores de escolas públicas localizadas na Região Metropolitana de Fortaleza, CE (RMF) pertencentes a Secretaria Municipal de Educação, Ciência e Tecnologia - SMECT do município de Caucaia/CE sobre o uso das TDIC nas aulas de climatologia no ensino fundamental. Em adição, apresentam-se os resultados do uso das técnicas de Sensoriamento Remoto (SR) como método pedagógico nas aulas de climatologia nas turmas do terceiro ano do ensino médio. Os resultados mostraram o uso incipiente das TDIC como tecnologia educacional apesar do reconhecimento dos benefícios que essas ferramentas proporcionam no ensino de climatologia além da necessidade de um programa de formação continuada para os professores que atuam nessa faixa etária. A aplicação das técnicas de SR no estudo de ilhas de calor mostraram que essa metodologia representa um grande potencial como recurso didático e que facilitou a compreensão da formação desse fenômeno e seus efeitos no clima, na saúde e no bem-estar das comunidades que vivem nessas áreas além de auxiliar os estudantes na resolução das questões do Exame Nacional do Ensino Médio (ENEM).

Abstract This study presents the results obtained from a survey carried out with teachers from public schools located in the Metropolitan Region of Fortaleza, CE (RMF) belonging to the Municipal Department of Education, Science and Technology - SMECT of the municipality of Caucaia/CE on the use of TDIC in climatology classes in elementary school. In addition, the results of the use of Remote Sensing (SR) techniques as a pedagogical method in climatology classes in the third year of high school are presented. The results showed the incipient use of TDIC as an educational technology despite the recognition of the benefits that these tools provide in the teaching of climatology, in addition to the need for a continuing education program for teachers working in this age group. The application of SR techniques in the study of heat islands showed that this methodology represents great potential as a teaching resource and that it facilitated the understanding of the formation of this phenomenon and its effects on the climate, health and well-being of communities living in these areas. areas in addition to helping students to solve the questions of the National High School Exam (ENEM) and entrance exams.

Resumo: A importância da evolução como um eixo central da biologia é reconhecida por muitos autores. Este estudo descreve um curso voltado para esse fim, destinado à formação continuada de estudantes de biologia e professores. Pretendemos avaliar e comparar as respostas dos alunos antes e depois do curso através de um questionário de pesquisa desenvolvido e validado para as finalidades desta pesquisa. Os participantes são alunos de graduação e de pós-graduação em biologia de universidades públicas e privadas do sul do Brasil. Como nossos resultados indicam, os alunos de todos os níveis de formação em biologia se beneficiam de uma abordagem de ensino que trata a evolução como um eixo central do ensino de biologia. As comparações pré e pós-curso mostram que o nível de formação em biologia não indica um amplo conhecimento evolutivo e esta pode ser uma das principais vantagens de uma abordagem multidisciplinar no ensino da evolução.

Abstract: Although many authors share the view of evolution as the cornerstone of biological sciences, not many courses are effectively based off it. In this study, we have designed a course with this in mind, aimed at undergraduates and postgraduates in biological sciences. We intend to evaluate and compare the responses of both types of students using a survey questionnaire. Participants are undergraduate and graduate biology students from public and private universities in southern Brazil. We obtained 122 precourse and 95 post-course survey responses. Results suggest that students from all levels of biology training benefit from a teaching approach that takes evolutionary theory across biological disciplines. Pre- and post-course comparisons show that more training in biology does not equal more evolutionary knowledge. This may be one of the main advantages of a multidisciplinary approach to teaching evolution.

Resumo O objetivo deste trabalho foi quantificar os compostos fenólicos totais no mel monofloral de aroeira (Astronium urundeuva) e verificar, por meio de testes histoquímicos, se estes compostos estão presentes nos tecidos florais. O apiário, com abelhas Apis mellifera, foi instalado em meio a aroeiras, na região do semiárido do estado de Minas Gerais, Brasil. A partir da anatomia das flores e da raque da inflorescência, observou-se epiderme ornamentada, tricomas tectores e glandulares, idioblastos e sistema secretor desenvolvido. O mel de aroeira apresenta, em média, 142.5±22.6 mg 100 g-1 de compostos fenólicos totais, valor considerado muito elevado quando comparado aos de outros méis monoflorais provenientes do Brasil e do mundo. Os testes histoquímicos detectaram a presença de substâncias fenólicas nos idioblastos e nos ductos secretores associados ao floema nos tecidos florais, especialmente no parênquima nectarífero, na epiderme e nos tricomas glandulares. Os compostos fenólicos estão presentes no tecido floral de ambos os morfos florais, principalmente no nectário onde as abelhas coletam o néctar. Os resultados obtidos são os primeiros, na literatura, indicativos de que os compostos fenólicos produzidos pelas árvores de aroeira são transferidos através do néctar para o mel. Este estudo contribui para o estabelecimento de padrões de qualidade do mel de aroeira e para a identificação da sua origem botânica.

Abstract The objective of this work was to quantify the content of total phenolic compounds in monofloral honey from aroeira (Astronium urundeuva) trees and to verify, through histochemical tests, if these compounds are present in the floral tissues. The apiary, with Apis mellifera bees, was installed among aroeira trees in the semiarid region of the state of Minas Gerais, Brazil. From the anatomy of the flowers and of the inflorescence rachis, an ornamented epidermis, tector and glandular trichomes, idioblasts, and a developed secretory system were observed. Aroeira honey has an average phenolic content of 142.5±22.6 mg 100 g-1, a value considered very high when compared with those of other monofloral honeys from Brazil and around the world. Histochemical tests detected the presence of phenolic substances in the idioblasts and secretory ducts associated with the phloem in the floral tissues, especially in the nectar parenchyma, epidermis, and glandular trichomes. Phenolic compounds are present in the floral tissue of both floral morphs, mainly in the nectary where honeybees collect nectar. The obtained results are the first, in the literature, indicative that the phenolic compounds produced by aroeira trees are transferred through the nectar to the honey. This study contributes to the establishment of quality standards for monofloral aroeira honey and to the identification of its botanical origin.

Resumo A evolução biológica é frequentemente considerada um eixo central e unificador da biologia. O artigo discute aspectos históricos desse ideal de unificação, bem como os seus sinais de desintegração entre os anos 1960 e 1980. Argumentamos que apesar das novas propostas de síntese do conhecimento biológico, a biologia evolutiva contemporânea é caracterizada por um pluralismo. Os principais pontos a favor do pluralismo evolutivo são discutidos, e algumas consequências dessa perspectiva são apresentadas, particularmente em relação ao ideal de unificação da biologia. Por fim, defendemos um pluralismo evolutivo crítico do ideal de unificação como um objetivo da ciência, mas ainda favorável a integrações locais.

Abstract Biological evolution is often regarded as a central and unifying axis of biology. This article discusses historical aspects of this ideal of unification, as well as signs of its disintegration from the 1960s to 1980s. We argue that despite new proposals for the synthesis of biological knowledge, contemporary evolutionary biology is characterized by pluralism. The main points in favor of evolutionary pluralism are discussed and some consequences of this perspective are presented, particularly in terms of the ideal of a unified biology. Finally, we defend an evolutionary pluralism that critiques the ideal of unification as a scientific objective, but still favors local integrations.

ABSTRACT OBJECTIVE To evaluate the performance of post mortem laboratory analysis in identifying the causes of hemorrhagic fever and/or neuroinvasive disease in deaths by arbovirus infection. METHODS Retrospective cross-sectional study based on the differential analysis and final outcome obtained in patients whose samples underwent laboratory testing for arboviruses at the Pathology Center of the Adolfo Lutz Institute, in São Paulo, Brazil. RESULTS Of the 1355 adults clinically diagnosed with hemorrhagic fever and/or neuroinvasive disease, the most commonly attributed cause of death and the most common final outcome was dengue fever. Almost half of the samples tested negative on all laboratory tests conducted. CONCLUSION The failure to identify the causative agent in a great number of cases highlights a gap in the diagnosis of deaths of unknown etiology. Additional immunohistochemical and molecular assessments need to be added to the post-mortem protocol if all laboratory evaluations performed fail to identify a causative agent. While part of our findings may be due to technical issues related to sample fixation, better information availability when making the initial diagnosis is crucial. Including molecular approaches might lead to a significant advancement in diagnostic accuracy.

Resumo Corretores ortográficos são ferramentas computacionais utilizadas cotidianamente na redação de textos e de mensagens ou, de forma oculta, na busca por informação e mineração de dados. Diante de sua relevância, o presente trabalho apresenta o percurso histórico de desenvolvimento dos corretores ortográficos e ilustra como, de forma simples, é possível criar um corretor ortográfico eficiente a partir da proposta de Norvig (2007). Salientam-se, também, algumas ferramentas e as estratégias empregadas na elaboração de corretores, como a remoção de afixos e a computação de n-gramas. Explicita-se, ainda, a implementação do corretor ortográfico de Norvig (2007) e verifica-se seu desempenho na tarefa de correção automática em diferentes conjuntos de dados de erros ortográficos. Expõe-se, também, uma comparação na performance de um corretor ortográfico que se vale da remoção de afixos em relação a um corretor que não adota semelhante estratégia.

Abstract Spell checkers are ubiquitous computational tools that help us in correctly writing texts or messages and improving information inquiry and data mining. The present work presents the history of development of spell checkers and illustrates how, in a simple way, it is possible to create an efficient spell checker from Norvig’s proposal. We also highlight some tools and how they are used in the development of spell checkers, such as affix removal and n-gram computation. Moreover, we present an implementation of Norvig’s spell checker and its performance in automatic correction for different spelling error data sets. Also, in a comparison of spell checkers performance, we expose that it is worth removing affixes.

Abstract Over the last decades, alloy 718 usage has expanded and requirements imposed by its industrial applications became more critical. The knowledge about grain boundary character distribution (GBCD) in alloy 718 and its effect on properties improvement is mostly built based on iterative processing through cold rolling steps interspersed with solution annealing. Alloy 718 is found in the industry in many different forms and geometries, and fabricated by multiple thermomechanical processes such as wire drawing, rolling, forging or extrusion. The present study focused on understanding how wires respond to deformation mode related to drawing in regard to GBCD evolution, crystallographic orientation, precipitation of δ-phase and grain size. Lastly, assessing the resulting mechanical properties. The findings show that microstructural evolution is a consequence of competing mechanisms such as strain induced boundary migration, recrystallization, grain growth and phase precipitation. The deformation gradient along wire cross section plays an important role in affecting microstructural features, such as δ precipitation, GBCD and microtexture.

RESUMO O presente trabalho apresenta os resultados de um programa de pesquisa cujo objetivo principal é o desenvolvimento de consumíveis adequados para a soldagem de componentes de ancoragem fabricados em aços de alta resistência. Após avaliação de diferentes composições químicas, com base no balanço de Mn e Ni é feita uma análise detalhada das propriedades mecânicas e microestruturais da composição química que propiciou os melhores resultados para permitir uma conclusão decisiva. Foram soldadas juntas pelo processo eletrodo revestido utilizando consumíveis de 4,0 mm de diâmetro, com preaquecimento de 200 ºC, corrente contínua, posição plana e energia de soldagem nominal de 1,5 kJ / mm. Após a soldagem, foram realizados ensaios mecânicos (tensão, impacto Charpy-V, dureza) e metalográficos por microscopia ótica, microscopia eletrônica de varredura e EBSD em amostras removidas integralmente do metal de solda, tanto na condição de como soldado quanto após tratamento térmico pós-soldagem (TTPS) realizado a 600 ºC. Os resultados mostram que os metais de solda obtiveram propriedades mecânicas satisfatórias após o TTPS, sendo adequados para aplicação em componentes de ancoragem de acordo com a especificação IACS W22. Além disso, observou-se que a tenacidade ao impacto experimentou uma melhoria com o aumento do tempo de TTPS, o que é crucial para componentes com maiores espessuras.

ABSTRACT The present work show the results of an extensive working program whose the main goal is the development of consumables suitable for welding of mooring components manufactured in high strength steels. After an exhaustive evaluation of different chemical compositions, based on a balance of Mn and Ni, a detailed analysis of the mechanical and microstructural properties is done for the heat which proposed the best results in order to allow a decisive conclusion. Welded joints were produced by using 4,0 mm diameter covered electrodes, with preheat of 200 ºC, direct current, flat position and nominal heat input of 1.5 kJ/mm. After welding, mechanical tests (tension, impact Charpy-V, hardness) and metallographic examination (optical microscopy and scanning electron microscopy, electron back scattering diffraction) were performed in specimens removed integrally from the weld metal both in the as welded condition and post weld heat treatment at 600 º C. The results show that the weld metals obtained satisfactory mechanical properties after PWHT, being adequate for application on high strength steel mooring components with several grades according to the IACS W22 specification. In addition, it was noted that impact Charpy-V results were improved with increasing the time of PWHT, which is crucial for larger components.

RESUMO Introdução: A hibridização in situ cromogênica (CISH) é uma alternativa aos métodos tradicionais imuno-histoquímicospara diagnóstico de doenças infecciosas em amostras fixadas em formalina e incluídas em parafina, visto que apresenta grande sensibilidade e especificidade. Esse tipo de amostra sofre diversas modificações químicas durante o processamento histológico, e tanto a má fixação quanto a fixação em excesso podem prejudicar a qualidade das amostras, inviabilizando bons resultados. Na CISH, é comum a utilização de amostras positivas como controle de qualidade das reações; entretanto essa prática não fornece nenhuma informação a respeito da preservação do material genético, nem evita resultados falso-negativos nas amostras testadas. Objetivo: O objetivo deste estudo foi realizar a validação das sondas comerciais para ácido desoxirribonucleico (DNA) (+) e (-) e ácido ribonucleico (RNA) (+) e (-), para serem utilizadas como controle de qualidade, avaliando apreservação do material genético nas amostras testadas. Materiais e métodos: Foram utilizados 12 cortes histológicos (em quadruplicata, n = 48), confeccionados a partir de um pool de tecidos sem alterações microscópicas relacionadas com processos infecciosos e/ou inflamatórios. O protocolo de CISH foi conduzido de acordo com as instruções do fabricante e padronizado conforme as condições do nosso laboratório, utilizando sondas comerciais de DNA e RNA quimicamente ligadas à digoxigenina. Resultados e conclusão: Nossos resultados foram muito satisfatórios, demonstrando alta reprodutibilidade, acurácia, sensibilidade e especificidade analítica, bem como altos valores preditivos para ensaios positivos e negativos e com proporção nula de resultados falso-negativos e falso-positivos, o que possibilitou a validação dessa reação.

ABSTRACT Introduction: Chromogenic in situ hybridization (CISH) is used alternatively to the traditional immunohistochemical methods for the diagnosis of infectious diseases in formalin-fixed paraffin-embedded samples, since it presents high sensitivity and specificity. This type of sample undergoes several chemical modifications during histological processing, and both poor and excessive fixation can impair sample quality, making it difficult to obtain good results. In CISH, it is common to use positive samples as quality control for the reactions; however, this practice does not provide any information regarding the preservation of the genetic material, nor does it avoid false-negative results. Objective: The objective of this study was to validate the deoxyribonucleic acid (DNA) (+) and (-), and ribonucleic acid (RNA) (+) and (-) control probes to be used as quality control for the samples, evaluating preservation of the genetic material. Materials and methods: Twelve histological sections were used (in quadruplicate, n = 48), prepared from a pool of tissues without microscopic changes related to infectious and/or inflammatory processes. The CISH protocol was conducted according to the manufacturer’s instructions, standardized under the conditions of our laboratory, using commercial DNA and RNA probes chemically linked to digoxigenin. Results and conclusion: Our results were very satisfactory, showing high reproducibility, accuracy, sensitivity and analytical specificity, high predictive values for positive and negative assays and with zero ratio of false-positive and false-negative results, allowing the validation of this reaction.

ABSTRACT Nickel-based weld overlays (cladding) are commonly used in oil & gas industry to extend the life of equipment under corrosive environment, as it improves the corrosion resistance without a significant increase in the manufacturing cost, when compared to a full nickel-based alloy equipment. Although there are extensive literature involving overlays applied by SMAW, GMAW or GTAW processes, works about the use of FCAW process are limited. Consequently, an investigation of the performance of the overlays deposited by this process, which provides a higher productivity in comparison to the processes usually used, can be an interesting option for this application. The present work evaluates the mechanical and microstructural properties of the nickel-based superalloy 625 weld overlay deposited on a ASTM A516 Grade 70 carbon steel plate by the flux cored arc welding process (FCAW), both in as welded and heat treated conditions. Bending and microhardness tests were performed in order to verify possible effects of welding thermal cycles on the mechanical properties. The microstructure was evaluated through both optical (OM) and scanning electron microscopy (SEM), with the use of electron backscatter diffraction (EBSD) technique. Corrosion tests were conducted on samples removed from the top layer of the weld overlay according to ASTM G 48 Method A. All results obtained with this welding process, in both as welded and heat treated samples, were considered satisfactory.
