Full textO mal das folhas é um dos mais sérios problemas patogênicos da seringueira no Brasil, sendo uma constante ameaça para as plantações do Oriente, principalmente Tailândia, Indonésia e Malásia, países responsáveis por 90 % da produção mundial de borracha natural. Esta doença causa desfolhamentos sucessivos às plantas em materiais suscetíveis, reduzindo a produção de látex e acarretando na mortalidade das plantas adultas. O objetivo do presente trabalho foi: caracterizar a anatomia foliar em três estágios fenológicos nos clones de seringueira PB 314, PB 235, MDF 180 e Fx 2784; aspectos anatômicos envolvidos com a patogênese do Microcyclus ulei em três clones (PB 314, PB 235 e Fx 2784) avaliados aos 5, 10, 45 e 90 dias após inoculação. Foi possível classificar três estágios (B, C e D) de acordo com os aspectos anatômicos. Verificou-se que PB 314 possibilitou o completo desenvolvimento do fungo nas fases assexual e sexual; MDF 180 apresentou alta concentração de compostos fenólicos no mesofilo, ausência da ascogênese e maior tempo da esporulação conidial que em PB 314; Fx 2784 apresentou maior espessura da epiderme da face abaxial, no estágio foliar B, que os outros clones, podendo ser considerada um fator de resistência anatômica à infecção e colonização pelo fungo.
The South American leaf blight is the most serious disease of rubber tree: is currently a serious threat to many regions of rubber plantation of the world, particularly in Indonesia, Tayland and Malaysia, responsible for 90% of natural rubber; and was the most important single factor in the complete failure of attempts to cultive rubber in the North region of Brazil. This disease caused successive defoliation in susceptible materials reducing the latex production and the plants death after third defoliation. The aim of this work was: a)To characterize the leaflets anatomy in three phenoligic stage in four rubber tree clones: PB 314, PB 235, MDF 180 and Fx 2784; b)Anatomical aspects involved with pathogenesis of Microcyclus ulei in three clones (PB 314, MDF 180 and Fx 2784) evaluated on 5, 10, 45 and 90 days after inoculation. It was possible classified 3 leaves stages (B, C and D) according to anatomical aspects. In PB 314 it was possible the complete fungus development in asexual and sexual stage, MDF 180 showed phenolic compounds concentration in the mesophil and the fungus ascogenese it was not possible, but the conidial sporulation was longer than PB 314; Fx 2784 has more larger thickness epidermic of abaxial surface in the B stage than the other clones, contributed with important anatomic factor of resistance to infection and colonization by fungus.

O maior problema fitossanitário na heveicultura brasileira é a doença conhecida por mal das folhas, causada pelo fungo Microcyclus ulei, cujos sintomas ocorrem nas folhas jovens, causando intensas desfolhas, diminuindo a produção de látex e até mesmo a morte em plantas muito suscetíveis. A espécie Hevea brasiliensis possui um hábito deciduifólio completo que é um caráter importante, ou seja, o desfolhamento uniforme proporciona a recuperação da copa com folhas sadias e a redução do inóculo de patógenos que são descartados com as folhas velhas, onde as estruturas reprodutivas estão localizadas. Os objetivos deste trabalho foram: utilizar ferramentas de sensoriamento remoto para confrontar o efeito das variáveis climáticas em diferentes períodos do ano sobre interferência do mal das folhas em seis anos comparando o avanço da doença com os índices de vegetação, Índice de Vegetação com Diferença Normalizada (NDVI), Índice de Vegetação Ajustado para os Efeitos do Solo (SAVI) e Índice de Área Foliar (IAF), calculados para o período de cada ano estudado, analisar o efeito deciduifólio natural ou ocorrência do mal das folhas; e verificar a troca de folhas dos clones de seringueira em estudo comparando com a fenologia. A área utilizada para o estudo localiza-se no município de Registro, Estado de São Paulo, Brasil, na Fazenda Umuarama com plantio monoclonal de seringueira, foram avaliados seis clones diferentes: IAN 873, IAN 717; RRIM 600, Fx 3864, Fx 2261 e Fx 3844, por meio das imagens do satélite Landsat 5 utilizado os índices de vegetação NDVI, SAVI e IAF. Foram utilizados para análise estatística modelos lineares generalizados com a distribuição gama e função de ligação logarítmica tendo como fatores clones e índices de reflectância. Os modelos foram ajustados incluindo-se as covariáveis continuas mensurada no campo: folhas caídas totais e folhas caídas doentes Esses modelos foram comparados através do critério de informação de Akaike corrigido – AICC, para identificar o melhor modelo, verificada mediante desvios por graus de liberdade (scale deviance). Para comparações entre fatores foi utilizado foi o teste de Tukey–Kramer. Realizou a correlação de Spearman entre os índices de vegetação: NDVI, SAVI e IAF. Concluiu-se que as ferramentas de sensoriamento remoto são aplicáveis nos efeitos que as variações climáticas sobre a influência da doença mal das folhas. Os índices NDVI, SAVI e IAF foram significativos para a queda foliar da seringueira. Verificou também através dos índices a fenologia da seringueira nos períodos de troca de folhas: desfolha, reenfolha e densidade de copa. Ocorreu interação estatística significativa sobre o efeito dos clones, sua fenologia e índices de vegetação nos pixels da imagem. Obteve-se bom ajuste dos modelos dos índices com as imagens de satélites e as covariáveis dos dados de campo. A correlação de Spearman mostrou-se significativa entre os índices por valores dos pixels. Os índices são ferramentas de grande valia para estudos e análises sobre plantios florestais.
The biggest phytosanitary problem in Brazilian heveculture is the disease known as leaf blight caused by the fungus Microcyclus ulei. Whose symptoms occur in young leaves, causing severe defoliation, reducing the production of latex and even the death in susceptible plants. Rubber tree has a deciduous habit which is an important character. Uniform defoliation of clones provides a reduction in the interior of pathogens, whose locations to reproduction occur in the old leaves. The objectives of this work were: Using remote sensing tools to compare the effect of climatic variables in different periods of the year on leaf mischief interference in six years comparing the disease progression with Normalized Difference Vegetation Index (NDVI), Soil Adjusted Vegetation Index (SAVI) and Leaf Area Index (LAI) vegetation indices, calculated for the period of each year studied, verifying the natural deciduous effect or occurrence of leaf blight; Estimate an exchange of leaves of the rubber tree clones under study, comparing them with phenology. The area used for the study is located in the municipality of Registro, São Paulo State, Brazil, at Umuarama Farm with monoclonal rubber plantation, IAM 873, IAN 717; RRIM 600, Fx 3864, Fx 2261 and Fx 3844, using Landsat 5 satellite images used in NDVI, SAVI and IAF vegetation indices. They were used for statistical analysis generalized linear model with logarithmic range distribution and binding function having as clones reflectance factors and indices. Set the same models including whether the continuous covariates measured in the field: total fallen leaves sick and fallen leaves. Compared these models through the Akaike information criterion corrected - AICC to identify the best model, verified through the deviations by degrees of freedom (scale deviance). Was compared between factors was used was the Tukey-Kramer test. Spearman correlation was performed between the vegetation indexes: NDVI, SAVI and LAI. It was concluded that remote sensing tools are applicable in the effects that climatic variations on the influence of evil leaf disease. The NDVI, SAVI and IAF indexes showed the leaf fall effect of the rubber tree. Also verified through the indices the phenology of the rubber tree in the periods of leaf change: defoliation, re-foliage and cup density. There was a statistically significant interaction on the effect of clones’ phenology and vegetation index in the pixels of the image. It obtained good adjustment of the models of the contents with the satellite images and field data covariates. The Spearman correlation coefficient was significant between the indexes through the values of the pixels. The indices are valuable tools for studies and analyzes on forest plantations.

A seringueira (Hevea spp.) é uma planta nativa da região amazônica, da qual se extrai o látex para a fabricação da borracha natural. O Brasil já foi o maior produtor mundial de látex, e este já foi responsável por 40% da exportações brasileiras. Esta planta é suscetível ao ataque do fitopatógeno Microcyclus ulei, causador do mal das folhas da seringueira, que é também endêmico da região amazônica e o principal responsável pela queda de produção de látex na América Latina e perda do mercado para países asiáticos como Sri Lanka e Malásia. Entretanto, surgiu dentro deste contexto o fungo micopatogênico Dicyma pulvinata que apresenta alta capacidade de controle do fitopatógeno M. ulei. Considerando esse fato, D. pulvinata pode ser utilizado como uma ferramenta para o controle biológico do mal das folhas da seringueira. Neste trabalho foi analisada a capacidade de produção de glicosil hidrolases (β−1,3-, β−1,3-1-4- e β−1,4-glucanase e quitinase ) por dois isolados CEN62 e CEN93, que haviam demonstrado, em estudos anteriores, serem bons antagonistas do fitopatógeno M. ulei. Assim, foi iniciado um projeto de avaliação da capacidade de produção dessas enzimas por estes dois isolados, e a caracterização de suas propriedades bioquímico-moleculares. Os dois isolados demonstraram capacidades de produção das enzimas β−1,3-, β−1,3-1,4-glucanase e quitinase. No entanto, apenas o isolado CEN62 apresentou atividade de β-glucanase no sobrenadante do meio de cultura. Nenhum dos dois isolados secretou atividade de quitinase. Entretanto, a atividade de quitinase significativa foi encontrada associada ao micélio. Não foi possível, no entanto, a identificação de moléculas relacionadas a essa atividade, quer seja procedendo a lise do micélio na presença de detergente, quer procedendo a lise por sonicação Assim, foi escolhido o sobrenadante do meio de cultura do isolado CEN62 para etapas posteriores de purificação, por apresentar uma atividade de β−1,3-glucanase. O sobrenadante do meio de cultura do isolado CEN62 foi então caracterizado bioquimicamente, observando-se que a atividade de β−1,3-glucanase teve um máximo a 60ºC e pH 5,5, e a atividade de β 1,3-1,4-glucanase o máximo foi de 50ºC e pH 5,5. A β−1,3-glucanase apresentou atividade correspondente a uma meia vida de 10 e 1 minutos a 70ºC e 80ºC respectivamente. O sobrenadante do meio de cultura do isolado CEN62 de D. pulvinata , crescido por dez dias em meio contendo quitina como fonte de carbono, apresentando atividade de β-1,3-glucanase, foi ultrafiltrado com uma membrana de exclusão de 30kDa, concentrado e submetido a uma cromatografia de troca iônica em resina S-Sepharose. Essa cromatografia resultou em um pico de proteínas com atividade de β-1,3-glucanase o qual foi em seguida, recromatografado em uma coluna de troca iônica (DEAE-Sepharose). Um novo pico de proteínas com três espécies protéicas foi obtido, conforme mostrado em gel de poliacrilamida em condições desnaturantes. O rendimento deste processo de purificação parcial desta β-1,3-glucanase foi de 0,023%, e o fator de purificação de 345,3 vezes. _______________________________________________________________________________ ABSTRACT
The rubber tree (Hevea spp.) is a native plant from the amazonic region, from which the latex is extracted in order to make the natural rubber. Brazil once was the mundial leader in latex production, and it was the responsible for 40% of brazilian exportations. However, this plant is vulnerable to the attacks from the phytopathogen Microcyclus ulei, agent of the leaf blight of the rubber tree, and is also endemic from the amazonic region and the main responsible for the fall in production in latex in latin America, and loss of market shares for the asian countries of Sri Lanka and Malasia. Nonetheless, in this context, the mycopathogen fungus Dicyma pulvinata came forth, and shows high capacities in the biological control of M. ulei. Base don this, there is a new alternative for the biological control for the leaf blight of the rubber tree. In this work the capacity of production of glicosyl hidrolases (β−1,3-, β−1,3-1-4- e β−1,4-glucanase e quitinase) of two isolates CEN62 e CEN93, which had demonstrated in anterior studies to be good antagonists of the phytopatogen M. ulei, were analyzed. Then, a project started to evaluate the capacity of production of these enzymes by these two isolates, and the characterization of their biochemical and molecular properties. The two isolates have demonstrated capacity to product the enzymes β−1,3-, β−1,3-1,4-glucanase and quitinase. Nevertheless, just the isolate CEN62 demonstrated activity of β-glucanase in the medium filtrate. None of the isolates secreted quitinase activity. However, a significant activity of quitinase was found associated to the mycelium. It was not possible, however, to extract this activity nor by cell lysis using detergent, nor by lysing by sonication.Then, the CEN62 medium filtrate was chosen for further purification steps, by showing β−1,3-glucanase activity. The isolate CEN62 medium filtrate was then biochemically characterized, being possible to evaluate that the β−1,3-glucanase activity had a maximum at 60ºC and pH 5,5, and the β 1,3-1,4-glucanase activity had its maximum at 50ºC and pH 5,5. The β−1,3-glucanase activity showed a half-life period of tem and one minutes at 70ºC e 80ºC respectively. The CEN62 medium filtrate of D. pulvinata after growing for tem days in medium containing chitin as carbon source, and containing β-1,3-glucanase activity was ultrafiltrated with an exclusion membrane of 30kDa, and the concentrated was submitted to ion exchange chromatography in S-Sepharose resin. This chromatography resulted in a protein peak with β-1,3-glucanase activity, which was, thereafter, rechromatographed in a ion exchange column (DEAE-Sepharose), resulting in a new protein peak, with three protein species as shown in SDS-PAGE. The yield of this process of β-1,3-glucanase partial purification was of 0,023%, and purification factor of 345,3 times.

O mal das folhas da seringueira (MDF) é uma doença destrutiva causada pelo fungo Pseudocercospora ulei que pode afetar severamente a seringueira em monocultura na América tropical. O agente causal da doença é um patógeno hemibiotrófico que apresenta crescimento lento in vitro. O isolamento de DNA de boa qualidade em quantidades adequadas não é uma tarefa fácil devido à falta de um protocolo padrão e a dificuldade de cultivar P. ulei em condições de laboratório. Embora o MDF seja conhecido por mais de um século, informações sobre a estrutura genética na região amazônica, seu centro de origem, permanecem desconhecidas. Neste trabalho foram avaliados protocolos adequados para a extração de DNA e a estrutura genética da população de P. ulei na região amazônica. Foram comparados seis protocolos de extração em relação a pureza e ao rendimento do DNA. Um total de 61 isolados foram amostrados ao longo das bacias hidrográficas Madeira, Purus e Juruá localizadas na região amazônica e genotipados para 12 locos SSR. O protocolo de extração de DNA de Doyle e Doyle foi o único que apresentou concentração consistente e melhor qualidade do DNA extraído. Houve desequilíbrio de ligação entre os alelos e diferenciação genética entre populações geograficamente distantes foi detectada. A análise de componentes principais revelou agrupamento dos isolados de acordo com os limites das bacias hidrográficas. Foram formados dois grupos, um constituído pelos indivíduos da bacia do rio Madeira e o outro composto por indivíduos dos rios Purus e Juruá.
South American leaf blight (SALB) is a destructive disease caused by the fungus Pseudocercospora ulei that can severely affect rubber tree in monoculture in tropical America. The causal agent of the disease is a hemibiotrophic pathogen, that grows slowly under in vitro conditions. Isolation of good quality DNA in proper quantities is not an easy task due to the difficulties in the handling of P. ulei under laboratory conditions and the lack of a standard protocol. Although SALB has been known for nearly a century, information on the genetic structure of P. ulei in the Amazon region, its center of origin, remains unknown. In this work, adequate protocols for DNA extraction were assessed and the population genetic structure of P. ulei in the Amazon region was determined using 12 microsatellite loci (SSR). Six extraction protocols were compared regarding yield and purity of the DNA. A total of 61 isolates were sampled along the Madeira, Purus and Juruá watersheds located in the Amazon region and SSR genotyped. The Doyle and Doyle DNA extraction protocol was the one that presented consistent and better quality extracted DNA. There was linkage disequilibrium between alleles and genetic differentiation between geographically distant populations was detected. Principal component analysis revealed clustering of the isolates according to the watershed boundaries. Two groups were formed, one comprised by individuals from the Madeira river and the other comprised of individuals from the Purus and Juruá rivers.

Full textSouth American Leaf Blight (SALB) caused by the fungus Microcyclus ulei is a serious threat to worldwide rubber tree cultivation and also responsible for the poor development of this culture in South and Central America. The breeding of resistant cultivars is considered as the best way to anticipate an accidental introduction of SALB in disease free countries and to develop rubber tree cultivation in diseased areas. The main resistance source described until now proved to be ineffective against the most aggressive fungus isolates. Another resistance source identified in a Peruvian cultivar holds for more than thirty years in high infestation conditions. Genetic mapping carried out on the progeny of a cross between this cultivar and a susceptible one revealed two major resistance genes, one located on linkage group g15 and effective against M. Ulei isolates from French Guiana, and the other one on linkage group g13 effective against isolates from Bahia state (Brazil). Diversity analysis in South-West Amazonian natural populations shows populations structured in three main clusters corresponding to the Brazilian states of Acre, Rondônia and Mato Grosso. The Madre de Dios population in Peru is part of the Acre genetic cluster. Differentiation among populations is mainly explained by isolation by distance and secondarily by the existence of hydrographical basins. The linkage disequilibrium between linked neutral genetic markers is wider in Acre cluster than in Rondônia cluster, but remains low in both cases. A genetic association with the SALB resistant trait is detected with a microsatellite marker located close to the major resistance gene in linkage group g15. Another association is also detected in a genomic area where no resistant locus was expected until now. Importance of these results for breeding of new SALB resistant cultivars is discussed

Full textIt is widely accepted that a team’s success is verified by their ability to score more goals than its opponent during a game. Therefore, scoring is the major point for any successful team. Due to the fact that the defensive side (of the game) has substantially improved, it has been increasingly difficult to surprise the opponents, so the coaches have bet on set pieces (SP) to be able to solve a match and be victorious. The SP occur very frequently during a football match, because regarding it is an opposition game, in which physical contact is allowed, faults frequently happen. Thus, we can verify the true importance that the SP may hold in modern football. In the field of action, the practice allowed us not only to understand the relationship between the game model, training model and game observation model, but also to relate the observation process to the training process. It has still been possible for us to achieve how the construction of a squad can be decisive for Set Pieces; In the research study, we have watched a total of 278 games, during which 632 goals were analysed, of which 170 were obtained through SP. Of the total number of goals scored through SP, it should be mentioned that 66 correspond to Sporting Clube de Portugal matches (2016/2018 seasons), 13 correspond to Club Sport Marítimo matches (season 2017/2018) and the remaining 91 were goals scored in the UEFA Champions League (2017/2018 season). Thus being, the study was based on the analysis of 171 SP goals with the objective to only analyse the ones obtained through SP (free kick, corner kick and penalty kick) in the modern football. It was identified that in Sporting Clube de Portugal in the 2016/17 and 2017/18 seasons there was high prevalence of goals scored through ET in the corner kicks. However, we also observed differences in the way they were executed in both seasons. In the first period analysed, the Spin-In kicks were the more prevalent, whereas in the second period, the Spin-Out kicks took more relevance. This may demonstrate the adaptation that occurred due to differences in ET performers. Moreover, we concluded that the finishing zone where most goals are scored through ET (corner kicks and free kicks) is the central zone. Regarding the area of community relations, we organized a seminary with the theme “Preparação e Construção do Modelo de Jogo”. It was conducted by Bruno Dias, a football coach. In summary: i) a coach’s work is based on three pillars: planning, operationalising and reflecting; ii) the team playing model, the training model and game analysis model are unfinished processes in constant evolution and in need of reflection in order to be improved in time; iii) a coach’s adapting capabilities is a crucial characteristic for leadership, regarding that many times what was planned has to be replanned; iv) the coach’s virtues have to be in line with those of his players so that they believe in the ideas of the Game Model.

Full textThis dissertation consists of a study which focuses on the management control system (MCS) of the company Ferro - Grupo Ferpinta. The research method used for this purpose is purely qualitative. Four interviews were done with individuals all having different responsibilities in the company aiming to obtain a holistic view. The study begins with a description of the organization and its components, as well as the main historical and strategic milestones. Secondly, the Execution Premium model is applied to Ferro's reality, seeking to highlight the main components of its MCS and the way in which it is interconnected. Here the main mechanisms and tools for monitoring the MCS are identified. In order to assess the impact of these tools on the system's execution, a study is conducted to assess their characteristics, such as the intensity of use, which ends up questioning the model's own framework and its adaptability to the reality of the organization under analysis. As a way of responding to this condition, this thesis establishes a parallel between Execution Premium and another tool, seeking to highlight the characteristics of a cyclical model. Through this analysis, the dissertation ends with the rationalization of the cyclical form of the framework and also the materialization of a new perspective - the Strategic Microcycles - that justify the importance and contribution of the monitoring tools.

Anemia is the common hematological disorder. It’s difficult to differential both of thalassemia (THA) and Iron deficiency anemia (IDA) often seen belongs to microcyte anemia. The CBCs is objective clinically that physician diagnoses anemia in proportion 1:4 between Iron deficiency anemia with thalassemia because of two anemia express the feature similarly with MCV less than 80 fL (fluid ounces). It will be more serious to the therapy of the patient when physicians do the same diagnosis. It’s novel to use soft computing that include FCM, Competitive learning, and ANFIS that parallels the human mind to process imprecision and uncertain in circumstance. It suit for to assist with physicians to diagnose clinically of the anemia that with the imprecision and uncertain.

Thus, supported by a strong supporting professional practice literature review, we focus our analysis on the organization and management of training and competition in a professional football context, with a special focus on the planning and operationalization of training, the distribution of its contents, the control of the training load and the prescription of the complementary training of performance potentiation and injury prevention. This analysis starts from the description and presentation of a standard training microcycle and the principles underlying its design. Cumulatively, we presented a project that results in the elaboration of a technical guidebook for the young footballers sports training process of the Vitória Futebol Clube. As the continued education of coaches is a fundamental point for the acquisition and consolidation of knowledge aimed to obtaining a greater and better performance, we’ve organized a community relationship event held at the Faculty of Human Kinetics - the FMH Football Day 2017. This report is the result of an in-depth reflection on the lived experiences about the conception of long-term youth football developmental programmes and the training and competition processes in high performance football teams.

Full textIntroduction: Regenerative endodontic therapy in immature teeth with necrotic pulps triggers continued root development, thereby improving the prognosis of these teeth. Disinfection of the canal is accomplished with an intracanal medicament, such as triple antibiotic paste (TAP) composed of metronidazole, ciprofloxacin, and minocycline. A modified triple antibiotic paste (MTAP) that replaces minocycline with clindamycin has recently been suggested to avoid the tooth discoloration and potential demineralization from minocycline. The effect these pastes have on radicular dentin is unknown. Objectives: The aim of this study was to investigate the effects of two intracanal medicaments used during endodontic regeneration, TAP and MTAP, at concentrations of 1 g/mL and 1 mg/mL, on the microhardness and chemical structure of radicular dentin. Materials and Methods: Roots from extracted, unrestored, non-carious human premolar teeth were sectioned. An antibiotic paste (MTAP or TAP) or sterile water (control) was applied to treatment groups and stored for four weeks in 80-percent humidity at 37 °C. The effect of each paste on the microhardness of radicular dentin was measured using a Vickers Microhardness Tester (n = 17) to take three pretreatment and post-treatment measurements at both 500 µm and 1000 µm from the pulp-dentin interface. The chemical structure was assessed from dentin specimens treated with the same medicaments or sterile water for four weeks. After treatment, three measurements were taken on each specimen using Attenuated Total Reflection Fourier Transform Infrared Spectroscopy to measure the phosphate/amide I ratios of dentin (n = 7). Results: The 1 g/mL of TAP or MTAP and the 1 mg/mL methylcellulose-based TAP caused significant reduction in microhardness of roots compared with untreated control roots at 500 µm and 1000 µm from the pulp-dentin interface. Furthermore, the methylcellulose-based 1 mg/mL TAP and MTAP caused significantly less reduction in microhardness compared with 1 g/mL TAP and MTAP. The 1 g/mL of TAP and DAP caused significantly lower phosphate/amide I ratios compared with other groups. Conclusion: The use of methylcellulose based 1 mg/mL of TAP and MTAP may minimize the reduction in microhardness of roots compared with the currently used 1 g/mL concentration of these antibiotics.
