Authors: Veiga D.C. , Santos G.C. , Sousa M.G.
Published: October 2019

RESUMO A degeneração mixomatosa valvar mitral (DMVM) costuma ser diagnosticada pelo ecocardiograma, porém o eletrocardiograma (ECG) pode sugerir alterações específicas e auxiliar no diagnóstico e no tratamento. A deflexão intrinsecóide (DI) é uma medida simples do ECG, que representa o início da despolarização ventricular e pode indicar a presença de sobrecargas e hipertrofia no ventrículo esquerdo. O objetivo deste trabalho é comparar dados prévios sobre condição clínica e ecocardiograma de cães com endocardiose de mitral e o valor da deflexão intrinsecóide do ECG, para buscar uma relação de concordância. Foram selecionados os arquivos de 45 cães anteriormente atendidos na rotina clínica do HV-UPFR. A estatística mostrou diferença relevante nos grupos B1, B2 e C nas derivações D2, D3, aVF, rV, V2 e V4 (P<0,05), o que permitiu classificá-los de acordo com o tamanho da DI, e esse resultado correspondeu à classificação do consenso de endocardiose de mitral em cães nesses estágios. Concluiu-se que há um aumento gradativo no valor da DI à medida que a DMVM avança, principalmente nos estágios B1, B2 e C, associado à sobrecarga e à hipertrofia ventricular esquerda, portanto esse parâmetro pode ser usado na classificação da doença.

ABSTRACT There is a growing interest in the study of unspecialized mesenchymal stem cells, for there are still some discussions about their in vitro behavior. Regenerative medicine is a science undergoing improvement which develops treatments as cell therapy using somatic stem cells. In several studies, adipose tissue is presented as a source of multipotent adult cells that has several advantages over other tissue sources. This study aimed to characterize and evaluate the tagging of mesenchymal stem cells from the agoutis adipose tissue (Dasyprocta prymonolopha), with fluorescent intracytoplasmic nanocrystals. Fibroblast cells were observed, plastic adherent, with extended self-renewal, ability to form colonies, multipotency by differentiation into three lineages, population CD90 + and CD45 - expression, which issued high red fluorescence after the tagging with fluorescent nanocrystals by different paths and cryopreserved for future use. It is possible to conclude that mesenchymal stem cells from agouti adipose tissue have biological characteristics and in vitro behavior that demonstrate its potential for use in clinical tests.

RESUMO Com o presente estudo, objetivou-se avaliar o tempo de fornecimento de náuplios de artêmia e o período de transição alimentar para pós-larvas de acará-severo (Heros severus). Foram utilizadas 450 pós-larvas de acará-severo, distribuídas em 45 aquários, em delineamento inteiramente ao acaso, em esquema fatorial 3x5, com três repetições. Foram avaliados três períodos de fornecimento de náuplios de artêmia: zero, cinco e 10 dias. Além disso, foram testados cinco períodos de transição alimentar: um, dois, três, quatro e cinco dias, quando os animais receberam alimentação conjunta de náuplios de artêmia e dieta farelada. Ao final do experimento, os peixes foram contados, pesados e fotografados, para avaliação do desempenho produtivo e das variáveis morfométricas. Para todos os parâmetros avaliados, não foi constatada interação entre o tempo de fornecimento de artêmia e o período de transição alimentar. Os animais alimentados por 10 dias com náuplios de artêmia apresentaram os melhores resultados de desempenho e as maiores variáveis morfométricas. Os peixes que receberam alimentação conjunta por três dias apresentaram desenvolvimento satisfatório. Dessa forma, recomendam-se 10 dias de fornecimento de náuplios de artêmia e três dias de transição alimentar, antes de se iniciar o fornecimento exclusivo de dieta inerte para pós-larvas de acará-severo.

ABSTRACT The objective of this study was to evaluate genetic aspects related to production and reproductive efficiency of Murrah and Mediterranean buffaloes and their crosses. A ranking of bulls from Embrapa Eastern Amazonia was also composed to guide assisted mating. Birth records of 2,322 Murrah, Mediterranean, and crossbred buffaloes from the Embrapa Eastern Amazon herd, from 1953 to 2013, as well as information on production and reproductive traits were used. Genetic analyzes were performed in the WOMBAT software using the animal model with two-trait analysis. While heritability (h2) for total milk production (TMP) and fat milk percentage (F) were generally high, for reproductive traits h2 tended to be low. Genetic correlations for TMP with the other traits were low and negative, except for TMP with calving interval (CI) and service period (SP) in the Mediterranean breed and with age at first calving (AFC) and SP in crossbred, which were positive and high. Bull 1001 had high predicted transmitting ability (PTA) for TMP, so it should transmit a greater volume of milk to his offspring, although it had a lower PTA for F. There was sufficient variability within the herd to work with genetic management for both production and reproductive efficiency.

ABSTRACT The objective of the present study was to establish the bioclimatic zoning by the temperature and humidity index (THI), considering a historical period and a future scenario, in order to represent the thermal environment for broiler breeding in the State of Minas Gerais. A historical series (1976 - 2014) of THI minimum, average and maximum calculated based on data from 48 conventional meteorological stations was used, belonging to the National Institute of Meteorology of the State of Minas Gerais. The analysis of the temporal series was based on the Mann-Kendall test and linear regression. A geostatistical analysis was also carried out to determine the comfort zoning of broilers as a function of the THI intervals. In this way, the THI spatial mapping methodologies and trend analysis for the prediction of a possible future climate scenario can help in the development of risk maps for monitoring thermal comfort of broilers, being indispensable in the planning of actions for the mitigation of the climatic change impacts on the productive chain of the State of Minas Gerais.

RESUMO Objetivou-se avaliar Urochloa spp. submetida a duas situações de estresse hídrico: déficit e alagamento. As forrageiras estudadas foram: U. humidicola cv. Tully, U. humidicola cv. Llanero, U. brizantha cv. BRS Piatã, U. brizantha cv. Xaraés, U. decumbens cv. Basilisk e U. ruziziensis cv. Kenedy, e os parâmetros avaliados foram relacionados às características estruturais e morfogênicas. O trabalho foi desenvolvido em casa de vegetação pertencente à Unidade Universitária de Aquidauana. Os tratamentos consistiram em diferentes condições de umidade do solo: 50 e 80% da capacidade de retenção de umidade do solo, e lâminas de 0cm, 1cm e 5cm de água acima do solo, com quatro repetições, em delineamento inteiramente ao acaso. O modelo considerou o efeito de umidade do solo para cada espécie forrageira a 5% de significância. As características estruturais e morfogênicas do capim-tully não foram afetadas pelas diferentes condições hídricas aqui avaliadas. O capim-llanero não reagiu ao alagamento. O capim-piatã foi tolerante às condições de déficit hídrico e apresentou mecanismos de adaptação ao alagamento. A U. decumbens cv. Basilisk apresentou respostas adaptativas que melhoram sua tolerância ao alagamento. A U. ruziziensis cv. Kenedy apresentou-se inapta às condições de alagamento e de déficit hídrico.

Published: October 2019

RESUMO Uma mula hígida, de cinco anos de idade, foi atendida portando um aumento de volume na região abdominal lateral direita, estendendo-se da região inguinal até 25cm cranial à prega pré-crural, de 60 dias de evolução, após trauma com um touro. O volume era redutível e sem dor à palpação, com presença de intestino grosso envolvido por área circular hiperecogênica na imagem ultrasonográfica. O diagnóstico foi hérnia inguinal, e a paciente foi submetida à anestesia geral inalatória para abordagem cirúrgica pela região inguinal, onde se visualizou o ceco emergindo pelo anel inguinal externo, cujo diâmetro era de aproximadamente 10cm. O ceco apresentava coloração e conteúdo normais e parte do corpo e o ápice projetavam-se cranialmente para uma bolsa de tecido subcutâneo, que foi aberta para facilitar o reposicionamento do órgão ao abdômen, bem como para ampliar o anel inguinal externo. A paciente teve alta 18 dias após o internamento. Com base neste relato, é possível concluir que a hérnia inguinal indireta não encarcerada pode se desenvolver em fêmeas equídeas após trauma. De acordo com a literatura consultada, o presente estudo é a primeira descrição desse tipo de hérnia em uma fêmea equídea e a primeira envolvendo o ceco.

RESUMO O objetivo deste trabalho foi avaliar a pastagem, o desempenho, o conforto térmico e os parâmetros hematológicos de bovinos Nelore na fase de terminação em sistemas integrados de produção agropecuária com duas densidades de árvores (ILPF-1L= 196 árvores ha-1 e ILPF-3L=448 árvores ha-1) e em pleno sol (ILP). Foram avaliados a massa e a composição morfológica da forragem, o ganho médio diário, o ganho de peso por área e a taxa de lotação no verão e no outono, bem como as variáveis climáticas dos sistemas em três horários e parâmetros hematológicos dos animais (n=60). A massa de forragem foi superior no tratamento ILP e no verão (P<0,05). Porém, a redução da massa de forragem nos sistemas ILPFs não interferiu no desempenho dos animais (P>0,05). A temperatura ambiente, a temperatura do globo e o índice de temperatura e umidade foram melhores nos tratamentos com sombreamento e no período da manhã, proporcionando maior conforto aos animais, sendo ainda confirmado pelo menor volume globular dos bovinos em ILP (P<0,05). Conclui-se que os sistemas com componente arbóreo diminuem a massa de forragem, mas essa redução não altera o desempenho dos animais na fase de terminação. Além disso, os sistemas ILPFs melhoram o conforto térmico, entretando essa melhora não foi suficiente para favorecer o desempenho.

ABSTRACT: Rust, caused by the biotrophic fungus Olivea neotectonae, stands out as an important disease in teak plantations in Brazil. Considering the current importance of this rust and the need to obtain additional basic information about its causal agent to better disease management, the present study aimed to analyze the morphology of O. neotectonae using light microscopy and demonstrate the infection process in teak leaves using scanning electron microscopy techniques (SEM). The morphological characteristics observed using light microscopy were similar to those described in the literature for this species. SEM revealed that the infection structures of the pathogen penetrated the teak leaf through the stomata complex. This study provides the first microscopic evidence of the infection process of Olivea neotectonae in leaves of teak plants.

Published: October 2019

ABSTRACT This article had the objective of reporting a case of aesthetic rehabilitation with laminated facets from the 14 to the 24 teeth made with IPS E.max Ceram ceramics (Ivoclar-Vivadent), which replaced previous unsatisfactory composite resin restorations in the anterior region. The patient had agenesis of 12 and 22 teeth, making it necessary to anatomize the anterior teeth. A digital smile design was first virtually created and then followed by a diagnostic wax-up. The following was performed in a single day: periodontal surgery using the flapless technique to achieve prosthetic space; teeth preparation; an additionalsilicone impression; and multiple provisional restorations of bis-acryl composite resins were fabricated. Fourteen days later, in the second session the ceramic veneers were etched with 5% hydrofluoric acid for 20s; they received a silane application and a silane heat treatment, then lastly an ultrasonic bath. A universal adhesive was used in combination with a light curing cement.Cementation was performed immediately following an occlusal adjustment. The patient returned for a follow-up appointment another fourteen days after the luting process, in which a further occlusal adjustment was performed, and he reported complete satisfaction with the treatment.

Published: October 2019

ABSTRACT Objective: The aim of the present study was to evaluate the influence, of immersion in different disinfectant solutions, on microhardness and surface roughness of a heat-cured acrylic resin. Methods: Specimens were immersed in distilled water, commercial vinegar for domestic use, sodium hypochlorite and hydrogen peroxide, for 150 hours or 300 hours (n=10). After periods of immersion, Knoop microhardness and surface roughness were evaluated using a microhardness tester and a roughness tester, respectively. The data were analyzed using two-way ANOVA and Holm-Sidak, at a level of significance of 5%. Results: The microhardness values ranged from 16.90 ± 0.33 to 17.80 ± 0.51 and roughness values from 0.05 ± 0.01 to 0.08 ± 0.02. There is no difference in microhardness and roughness between groups and times (p>0.05). Conclusion: Within the limitations of this study, it is possible to conclude that vinegar and hydrogen peroxide, as alternative disinfectant solutions for acrylic resin devices, did not promote deleterious effects on microhardness and polishing of a heat-cured acrylic resin used for the fabrication of prostheses, neither in the medium term nor the long term.

ABSTRACT Purpose: to describe pre and postnatal characteristics of children and adolescents with intellectual disability. Methods: study performed with all individuals who received healthcare between August 2016 and February 2018 at a reference Rehabilitation Center which serves 27 towns and cities in the South of Santa Catarina State, Brazil. A questionnaire focusing on demographic, socioeconomic, pre and postnatal variables was administered to parents or guardians of children and adolescents by trained interviewers. Descriptive analyses were performed using absolute and relative frequencies of categorical variables and central tendency and dispersion measures of numerical variables. Results: 42 individuals in the mean age of 11 years (± 3.0) were studied. Most mothers reported having unintended pregnancy and more than a half reported having had a cesarean section. In addition, about one-fifth of the subjects had low birth weight and most of them received exclusive breastfeeding up to six months of age. Conclusion: these findings are crucial for the organization and improvement of health care services, since they provide evidence for health professionals to improve and/or focus their health care initiatives on these individuals.

Published: October 2019

ABSTRACT Purpose: to analyze the influence of low-level laser on muscle performance and to identify the most used dosimetric parameters. Methods: the search for articles was carried out on the PubMed, BVS, Web of Science and SciELO platforms. The articles selected were original ones, with available abstracts and that evaluated the use of photobiomodulation on muscular performance. The data were analyzed according to the author, year of publication, sample, place of application, parameters evaluated, wavelength, dosimetry used and results found. Results: the final sample consisted of 27 articles published between 2008 and 2017. The sample size in the studies ranged from 8 to 60 individuals, aged from 17 to 70 years. A greater use of infrared wavelength, with punctual applications carried out in the path of the muscle, was observed. Regarding the dose, there was a variation from 0.24 to 50 joules per point. Of the total, only 5 (18.5%) studies had not found significant answers for the considered variables. Conclusion: most of the studies pointed out that low-level laser can improve muscle performance. The methodology used in the work was diversified, rendering data compilation difficult, being impossible to set the ideal parameters for this purpose.

Published: October 2019

ABSTRACT Purpose: to check the use of phonological processes in preterm infants. Methods: phonological evaluation was performed through the ABFW Child Language Test in 40 children, aged two to four years, i.e., 20 preterm and 20 full-term children, matched according to age, gender and socioeconomic level. Preterm children were evaluated at the State Center for Prevention and Rehabilitation of People with Disabilities - CEPRED; full-term children were selected and evaluated in a municipal nursery in the city of Salvador, BA, Brazil. The pertinent statistical tests were applied adopting the level of significance lower than 0.05%. Results: in the phonology test, the number of productive phonological processes not expected for the chronological age was statistically significant in the preterm group, especially syllable reduction, consonantal harmony, velar backing and liquid reduction. The high prevalence of cluster reduction and final consonant deletion, though still compatible with chronological age, shows the need to follow up the language acquisition of these children, after the age of four. Conclusion: the results evidenced the difficulty found by preterm infants in the development of phonological skills, emphasizing the importance of early diagnosis and speech-language monitoring in language acquisition.

Published: October 2019

ABSTRACT Purpose: to verify whether students screened with altered auditory temporal processing are more likely to present altered visual processing. Methods: the sample consisted of 68 children, aged from 9 to 12 years, 53% males, from the 5th and 6th grades of a public school. All children with alterations in the audiological or ophthalmological evaluation were excluded. The Duration Pattern Test (screening for auditory temporal skill), the Reading Perceptual Scale (visual stress symptom questionnaire and colored overlays selection) and the Rate of Reading Test (number of words correctly read per minute) were used. Appropriate statistical tests were applied adopting the significance level lower than 0.05. Results: participants screened with abnormal auditory processing had higher visual stress symptoms and lower reading rate, with a significant and moderate effect (p< 0.05; d< 0.71), when compared to their peers with normal auditory processing. Among the children with altered Duration Pattern Test, 58% improved the reading rate with the use of colored overlays, whereas 29% did so in the control group (Odds Ratio = 3.4, p = 0.017). Conclusion: children screened with altered auditory temporal processing presented a three times higher possibility of association with visual processing alterations, due to shared magnocellular system.

Published: October 2019

Abstract This study verified the predictive relationships between social skills, beliefs about love and marital satisfaction in the family life cycle. The participants of this study were 446 married adults, of both sexes, living in the metropolitan area of the city of Rio de Janeiro, Brazil. The explanatory variables that contributed most to the marital satisfaction of men were passion, proactive self-control, decision/commitment, and for women they were commitment, affective sensitivity, decision/commitment, and passion. It was concluded that the dimensions related to love constructs were more explanatory of marital satisfaction, except at the stage of couples with small children whose social skills were more prominent. These results may contribute to preparatory programs and therapies related to marital life.

Published: October 2019

Abstract This study’s objective was to assess the social skills, peer acceptance, and friendship among students involved in bullying situations transitioning from elementary to middle school. A total of 408 6th grade students from six public schools in the interior of São Paulo, Brazil composed the sample; 54.9% of whom were aged 11.3 years on average (Standard Deviation = 0.6). Data were analyzed using Analysis of Variance and Spearman’s correlation. In regard to social skills, bully-victims present a greater amount of passive and active responses when compared to victims, bullies, and not involved students. Only male bully-victims, however, experienced significantly more frequent rejection by peers, while female bully-victims had significantly fewer friends. The results indicate the need to develop interventions intended to prevent and decrease bullying in the period of school transition. Such interventions should, however, be gender-sensitive because of differences existing between boys and girls.
The place of care adolescents using psychoactive substances, according to their perspective
Authors: TRISTÃO Kelly Guimarães , AVELLAR Luziane Zacché
Published: October 2019

Abstract Caring for people using psychoactive substances is historically associated with segregatory practices, even with children and adolescents. This study aims to understand the place of care based on the discourse of adolescents. Participant observation and semi-structured interviews were conducted with six adolescent users of psychoactive substances met at a child and adolescent mental health service. The data were analyzed by thematic analysis and discussed in the light of analytical psychology and of the assumptions of the psychiatric reform. One can conclude that the place of care is not fixed, but depends on how it is carried out, understood, and received, and on how the relational processes are established in the service with the adolescent. From the therapeutic relationships built in the service, it can be understood as temenos, the safe and potentially therapeutic place, where the transformation and development process of the subjects can be supported.
A study about the characteristics of the contemporary parental exercise and care network
Authors: CAMPANA Nathalia Teixeira Caldas , GOMES Isabel Cristina
Published: October 2019

Abstract Considering the transformations that have occurred in the ways contemporary families operate, we propose an investigation on how heterosexual couples understand and exercise parenting, as well as on how they deal with the child care network. Based on qualitative methodology, 8 couples and their children’s pediatricians and educational coordinators were interviewed. The analysis of the results covered two categories: (1) The Construction of Parenthood and Care Network, and (2) Parental Exercise. Interviews were analyzed based on the perspective of psychoanalysis and psychosocial studies. We identified three possibilities for parenthood appropriation: (a) greater fluidity in parental roles, (b) egalitarian parental care, in which a greater value was assigned to the maternal figure, especially in the discourse made by parents and; (c) disruption with gender binarism in the parental exercise, but with a predominance of the responsibility for child care assigned to one of the spouses. As for sharing child care related tasks, both pediatricians and schools were seen as important parental tools.

Published: October 2019

Abstract This study investigates the way firms reconfigure their supply base and reshape their production network to capture value from Free Trade Zone incentives to capture value from incentives. Six production networks located in Manaus, Brazil are analyzed using the Global Production Network framework and factors related to plant type and supplier relationships. A multiple case study was conducted. Data was collected using in-depth semi-structured interviews administered in loco, and the selected the firms were leaders in three different industries: transportation, mechanical assembly and chemicals. The results indicate that, if effectively applied, incentives can impact production network configuration from an embeddedness perspective, causing a firm to change its strategic role. Based on the analysis, we propose five propositions that challenge the relationships among autonomy, value creation, plant types and levels of embeddedness. The propositions are particularly useful for suppliers and distributors, as well as public agencies, including infrastructure providers and policymakers.

Published: October 2019

Resumo Diversas modalidades de relacionamentos foram adotadas nas reestruturações industriais como estratégia de sobrevivência e desenvolvimento das organizações. A bioindústria demanda parcerias dado o elevado investimento técnico-científico necessário, entretanto, dificuldades existem para concretizá-las no Brasil. Na Amazônia, onde a agregação de valor no uso dos recursos da sua biodiversidade tem elevada importância para o desenvolvimento sustentável regional, estudos apontam dificuldades de interação entre empresas da bioindústria, academia e governo. Compreender estas dificuldades motivou este estudo, que tem como objetivo analisar a percepção dos empresários acerca dos relacionamentos interorganizacionais na bioindústria amazonense. Realizou-se uma pesquisa qualitativa com treze empreendimentos cujos dados foram coletados utilizando network pictures, complementadas com entrevistas semiestruturadas. Ainda que relações de amizade, confiança, entre outros atributos, tenham sido identificados como os principais fatores relacionais e que a complementaridade de recursos seja o principal motivo das parcerias, os relacionamentos estão aquém do que se preconiza para afirmar a existência de uma rede de negócios. Estes resultados evidenciam também a necessidade proposições de ações estratégias para aproximação dos atores desta indústria.
A rare case of PLA2R- and THSD7A-positive idiopathic membranous nephropathy
Authors: Wanderley David Campos , Jones Bárbara Dornelas , Barbosa Fabricio Augusto Marques , Araujo Stanley de Almeida
Published: October 2019

ABSTRACT Idiopathic membranous nephropathy (IMN) is a frequent cause of nephrotic syndrome in adults. In terms of etiology, the condition may be categorized as primary/idiopathic or secondary. Literature on the pathophysiology of IMN has indicated the presence of autoantibodies (PLA2R and THSD7A) directed against podocyte antigens. The detection of antibodies against a domain favors IMN. The presence of autoantibodies against one of the domains would in theory exclude the possibility of there being autoantibodies against the other domain. However, cases of patients with PLA2R- and THSD7A-positive disease have been recently reported, showing that antibodies against two targets may be concomitantly produced via yet unknown pathophysiological mechanisms. This study reports the case of a 46-year-old male patient with nephrotic-range proteinuria, hematuria, hypoalbuminemia, and hypercholesterolemia submitted to biopsy and histopathology examination (LM, IF, IHC, and EM) eventually diagnosed with PLA2R- and THSD7A-positive IMN associated with IgA nephropathy, stressing our experience with the use of IgG subclasses, PLA2R, and THSD7A in the workup for MN and the relevance of adopting a broad and adequate approach to elucidating and acquiring knowledge of the pathophysiology of IMN.
Ismar Tirelli Neto e as vias da extinção
Authors: Anglada Carolina
Published: October 2019

Resumo Este artigo busca ler a poética do escritor brasileiro Ismar Tirelli Neto em seus movimentos desassossegados de retorno, deambulação e desvio, que acabam por dessituar a própria noção de lugar (da memória, da poesia, das imagens) e do ter lugar da linguagem. Nesse caso, o intuito é analisar como a sua voz procura se encontrar à deriva, nos confins da linguagem, tornando-se irreconhecível em meio às incontáveis referências de cidades, bairros, cinemas, autores, muitos deles despercebidos, menores ou desaparecidos. Assim, intentamos dar a ver como certa poesia brasileira, em diálogo com toda uma tradição latino-americana ilhada, faz experiência dessa ausência de norte, mobilizando concepções fora de lugar e contribuindo sobremaneira para as relações entre literatura e política.
Bitcoin é moeda? Classificação das criptomoedas para o direito tributário
Authors: Castello Melissa Guimarães
Published: October 2019

Resumo Este artigo analisa a classificação jurídica das criptomoedas, a fim de, a partir dessa classificação, definir como se deve dar a incidência tributária em operações efetuadas com tais moedas. Para tanto, parte-se da análise do conceito de moeda no ordenamento jurídico brasileiro, com o intuito de definir se é viável classificar as moedas virtuais como moeda. No sentido de auxiliar nessa classificação, é efetuada uma breve análise do tratamento dado pelo Direito Comparado à matéria, em especial dos regramentos europeus. O estudo da experiência europeia é útil, na medida em que o Tribunal de Justiça Europeu já teve a oportunidade de decidir, no caso C-264/14 - Hedqvist, sobre a classificação jurídica das bitcoin, definindo se há incidência de Imposto sobre o Valor Acrescentado (IVA) em operações de compra e venda de bitcoin. Com base na experiência europeia e no conceito jurídico brasileiro de moeda, conclui-se que é possível considerar, para fins de incidência tributária, que operações financeiras com criptomoedas são semelhantes às operações com moeda estrangeira. A análise é feita tendo como pressuposto a necessidade de classificação de bitcoin e congêneres para o direito tributário, não tendo por objetivo estudar os impactos regulatórios que possam se originar a partir desta classificação.

Published: October 2019

Abstract The State of Parana is one of the Brazilian regions with the highest incidence of extraction of bromeliads, among the factors for the occurrence of this situation, they highlight a great demand for this species as ornamental flowers and the easy access to forests, few cultivation ponds and difficulties for farmers in cultivation processes, especially in the early stages of cultivation. The species Aechmea gamosepala Wittmack stands out among the species of this group of ornamental plants (Bromeliaceae) with strong commercial appeal and consequently of extraction. Given this context, a study was carried out to evaluate the germination and survival of seeds of the species. Five alternative types of substrates easily accessible to farmers were tested: coconut husk fiber, Plantmax®, earthworm humus, humidified Pinnus husk and sieved agricultural land. The experiment was conducted in a completely randomized design with 4 replications and 25 seeds per experimental unit at room temperature in a greenhouse, with sprinkler irrigation for a period of 90 days. The mean time for the onset of germination was 6.95 days, averaging 74.8% at the peak of germination, but there were no significant statistical differences between the treatments. For the seedling survival, humidified Pinnus husk substrates (70.8%) and coconut fiber house (80.4%) proved to be the best substrates for Aechmea gamosepala Wittmack.

Abstract Seaweed extracts are employed as biostimulants due to their beneficial effects on crop growth and yield. Ascophyllum nodosum seaweed extract aid to improve seedling growth and development, and decrease seedlings production costs; however, the correct concentration must be used in order to maximize the biostimulant effects. Consequently, this study aimed to analyze the effects of different concentrations of a seaweed-based (Ascophyllum nodosum) biostimulant on ornamental sunflower seed germination and seedling growth. Seeds of ornamental sunflower cv. “Sol Pleno” were sown in polyethylene trays containing commercial substrate. The treatments consisted of dairy spraying 60 mL of the solutions 0 (control), 5, 10 or 15 mL L-1 biostimulant on substrate. The experimental design was completely randomized with 4 treatments (concentrations of biostimulant) and 4 replicates (10 seeds replicate-1). The evaluated variables were percentage, index and time averages of germination, seedling height, fresh and dry mass of shoot and roots, and root system morphology (WinRhizo). The increase of the biostimulant concentration enhances seed germination and seedlings development. The concentration 15 mL L-1 biostimulant showed the best results for percentage and index of germination and the lowest mean germination time and increase plant height and fresh and dry mass of shoots in relation to the control treatment. Accordingly, 15 mL L-1 biostimulant (Ascophyllum nodosum) is recommended for ornamental sunflower “Sol Pleno” seed germination and seedlings growth.

Abstract Heliconias have great commercial importance due to their durability of inflorescences, sizes, forms and bright colors. Regarding its production, the mineral nutrition of the crop is one of the most relevant aspects to obtain quality floral stems. The objective was to determine the influence of N-P-K on the growth and nutritional content of Heliconia stricta Dwarf Jamaican. A completely randomized block design was used with four treatments and five repetitions. The treatments consisted in fertilizing the soil with N-P-K. The levels of fertilization expressed in kg ha-1 of NPK were: control without application 00-00-00 (T100), 31-31-31 (T231), 62-62-62 (T362) and 93-93-93 (T493). The plants received the treatments for six months. Growth variables and nutrient contents of heliconia biomass were evaluated. The analysis of variance showed significant statistical differences (P ≤ 0.05) in the vigor and color of the plant, as well as the phosphorus, magnesium and copper contents. The significant increases in vigor and color were with doses 31-31-31 and 62-62-62 of NPK. As for the contents of P, Mg and Cu were influenced by doses 31-31-31, 62-62-62 and 93-93-93 of NPK. This work shows important findings in relation to the nutritional diagnosis in the foliar content of nutrients.

Resumo Objetivou-se identificar de que maneira as tecnologias e a prática docente, frente à “Sociedade da Informação”, reforçam, ou põem em xeque, a percepção do professor sobre a sua autoridade. A reflexão sobre o conceito de autoridade de Hannah Arendt direcionou o pilar teórico e conceitual do estudo. Como resultado, identificou-se que o aluno possui facilidade em interagir com a tecnologia, mas essa facilidade não ultrapassa o seu uso no contexto comunicacional e de lazer; que o acesso dos alunos às novas bases informacionais pode gerar um sentimento de perda da autoridade por parte do professor despreparado; e que não é o domínio da tecnologia pelo professor que estabelece a sua autoridade, mas sim, a constituição de significado que é construído durante a relação educativa.

Abstract The relevance of current education towards the needs of 21st century society is questioned as most schools, especially in developing countries that offer their students homogenizing learning experiences in the 19th century style. This paper presents the results of a mixed-method study focused on identifying the main features of 21st century education as a concept that should promote lifelong learning experiences. The method combined a systematic literature review, survey application, visits to innovative schools and interviews with international educational experts. Results show the relevance of a soft skills-centered and purpose-oriented curricula, the activation of personal learning paths and the minimization of instruction in favor of research as a teaching approach. It is noteworthy that, although most of the results are widely discussed in the literature, they are currently presented with new possibilities of implementation and with a greater innovation potential, due to the technological evolution of our time.

RESUMO Com o presente estudo, objetivou-se comparar a técnica padrão do CXL com o tratamento utilizando a genipina como reticulante, com e sem desepitelização da córnea. Comparou-se propriedades químicas, mecânicas e morfológicas de córneas de suínos submetidas aos tratamentos de crosslinking com riboflavina egenipina, bem como comparar a citotoxicidade das soluções reticulantes, para possível aplicação no ceratocone. Para isso, as córneas foram divididas em quatro grupos: riboflavina e UVA conforme tratamento padrão, genipina com e sem desepitelização e controle sem reticulante. As córneas foram submetidas àscaracterizações de MO, MEV, ensaio de tração, dilatometria e intumescimento. A citotoxicidade foi realizada comparando o padrão com a genipina. Os resultados demonstram maior resistência à tração e maior grau de intumescimento quando a genipina foi aplicada após desepitelização da córnea. As inclinações descendentesna curva de dilatometria mostram-se lineares no UV-CXL e controle, e com a genipina, a contração tende a ficar mais acentuada em temperaturas maiores. Pela MEV foi verificada uma linha de demarcação no estroma corneano tratado com UV-CXL ou genipina e a MO exibiu padrões diversos de luz transmitida nos diferentesgrupos, demonstrando maior opacidade no UV-CXL. O crosslinking do colágeno corneano induzido pela genipina 0,1% produz aumento na resistência da córnea sem provocar opacidade corneana considerável, podendo ser útil no tratamento do ceratocone. O potencial de citotoxicidade aos fibroblastos se mostrou semelhante entre os métodos de reticulação.

ABSTRACT The objective of this research was to assess the spatial variability pattern concerning udder surface temperature in dairy cows that were healthy and in those with mastitis. A total of 24 animals were selected - eight healthy, eight with subclinical mastitis, and eight with clinical mastitis. Images were taken with a Flir i60 thermographic camera - resolution of 0.01°C, focal length of 1.0 m, and emissivity adjusted to 0.98 - between 05:00 and 07:00, totaling 96 images, three per animal, of the front and rear, right and left mammary quarters. Analyses were run through geostatistics, with semivariogram adjustment to validate the theoretical model and build kriging maps. The average surface temperature of the mammary quarters with positive classification for subclinical mastitis stood between 33.2 ± 0.67ºC and 34.64± 1.07ºC; for negative quarters, values ranged from 29.3 ± 1.78ºC to 32.24 ± 0.62ºC. The udder surface temperatures of healthy animals were lower than those of animals with subclinical mastitis (29.3ºC ± 1.78 and 31.58ºC ± 0.62). The udder surface temperature of animals with clinical mastitis was higher, between 34.0 and 37.5°C, compared to the other clinical statuses. The scale adopted for image pattern analysis successfully identified the spatial dependence of udder surface temperature, which helped standardize diagnostic procedures for healthy animals, and for those with subclinical and clinical mastitis, by means of geostatistics.

The results of studies of the regularity of sintering and properties of corundum-based ceramics with the addition of ultrafine powder (UFP) Al2O3 synthesized by electrochemical method are presented. It is shown that with an increase in the calcination temperature and the concentration of UFP Al2O3, a regular increase in linear shrinkage, microhardness and strength of ceramics is observed (the maximum values at 1550 °С are 27,8 %, 17 GPa and 340 MPa, respectively). The introduction of UFP Al2O3 allows even at a calcining temperature of 1550 °C to achieve an apparent ceramic density of 3,87 g/cm3. Ref. 12. Tab. 3.

Kadastro Sonucu Orman Sayılmayan Ağaçlık Alanlar: Gölcük Orman İşletme Şefliği Örneği

Türkiye’de orman tanımı,  sahip ve
sınırlarının tespiti ile sürekliliğinin sağlanmasında önemli yol kat edilmiş
olmasına rağmen bu konularda halen sorunlar yaşanmaktadır. Sosyal değişimler ve
teknolojik gelişmelerin de etkisiyle, ülke orman varlığında artışlar yaşansa da
yasa değişiklikleri ve yönetsel kararlarla orman ağaçları ile kaplı geniş
araziler orman sayılmamaktadır. Bu yaklaşım önemli miktarda orman alanının
yasal koruma dışında kalmasına sebep olmaktadır.  Yaşanan bu sorunun boyutu ortaya koymak ve
çözüm önerileri geliştirmek üzere Gölcük Orman İşletme Şefliği örnek alan
olarak seçilmiştir. Seçilen alanda, farklı zamanlardaki orman amenajman planı
verileri ile arazi kadastrosu sonucu belirlenmiş orman varlığı arasındaki
farklılıklar, konum ve büyüklük olarak irdelenmiştir. Ulaşılan sonuçlara göre,
1972 ile 2015 yılı arasında orman ağaçları ile kaplı alan %20 civarında
artmıştır. Ancak, arazi kadastrosu sonuçlarına bakıldığında, orman varlığındaki
artışın sadece % 20’si miktarında alanın orman varlığına dahil edildiği tespit
edilmiştir. Evvelinden beri orman olan veya üzerinde sonradan orman örtüsü oluşan
toplam 904,5 hektar arazinin ise kadastro uygulaması sonucunda orman
sayılmadığı görülmektedir. Bilimsel ölçütlere göre orman vasfı taşıyan
arazilerin orman dışında bırakılmasın en önemli sebebi, çok sınırlı haller
dışında özel orman mülkiyetine izin vermeyen mevzuattır. Yapılası gereken,
evvelinden beri devlete ait olan ormanların dışında kalan, tapulu arazilerde
var olan veya sonradan oluşan ormanların mülkiyetine müdahale edilmemesidir. Bu
yerler orman sayılmalı, sürekliliği güvenceye alınmalı, sahiplerinin
faydalanması için ormancılık teşkilatı yerel çalışanlarının yapacağı faydalanma
düzenlemesi ve kontrolü yeterli görülmelidir.
