Abstract: in a field trial involving 68 rubber tree (hevea spp.) clones calculation of genotypic correlation coefficients revealed significant age-age correlation from age 1 to 6 (immature period) for girth a and for age 7 to 12 (mature period) for girth b and for age 7 to 12 (production of latex) for yield. rank correlation coefficients between all immature ages of girth (girth a), all ages of mature girth (girth b) and all annual rubber production (yield) were significant for the three traits, with the coefficients decreasing with increasing age. selection of the sets of best 30, 15, 10 and 5 clones from the available 68 clones at a given age was generally accompanied by a descending order of percentage success. it was suggested: (a) to have the best 30 clones of age 6, select the set of best 36 clones at age 2, (b) to have the best 15 clones of age 6, select the set of best 20 clones at age 3, (c) to have the best 5 clones of age 6, select the set of best 8 clones at age 4, and (d) to have the best 3 clones of age 6, select the set of best 3 clones at age 5. more than 80% of the targeted clones on girth a or girth b basis and more than 76.7% clones on yield basis were found to get selected at steps (a) through (d). for achieving early multiplication of the most productive clone for deployment, multiplication should be started with the best 36 (i.e. 60%) clones selected at age 2.

Abstract: the objective of this study was to assess genotype-year interaction and determine temporal stable genotypes across six years of rubber yield evaluation. stability analyses were performed by eberhart and russell method for rubber yield. twenty-five genotypes were analyzed in a randomized complete block design with three replications. the best genotype in one year was not same always in the other year. the genotype components were partitioned into linear (genotypes within year) and nonlinear (pooled deviations) components. significant mean square for linear components was predictable. this indicated that the performance of genotypes across the years for rubber yield could be predicted. among the analyzed genotypes the iac 40 also was considered highly productive and vigorous, with suitable adaptation.

Abstract: twenty two open-pollinated hevea progenies from different parental clones of the asian origin were tested at five sites in the northwestern s?o paulo state brazil to investigate the progeny girth growth, rubber yield, bark thickness and plant height. except for the rubber yield, the analysis of variance indicated highly significant (p<0.01) genotype x environment interaction and heterogeneity of regressions among the progenies. however, the regression stability analysis identified only a few interacting progenies which had regression coefficients significantly different from the expected value of one. the linear regressions of the progeny mean performance at each test on an environmental index (mean of all the progenies in each test) showed the general stability and adaptability of most selected hevea progenies over the test environments. the few progenies which were responsive and high yielding on different test sites could be used to maximize the rubber cultivars productivity and to obtain the best use of the genetically improved stock under different environmental conditions.

Abstract: the fungigation of bean crops have been used in brazil by the agriculturists since the beginning of the 1980's. however, few surveys have been conducted to evaluate the efficiency of this technique. thus, the objectives of this work were to evaluate the efficacy of the fungicide epoxiconazol, applied through irrigation water, for the control of diseases in bean crops, under conventional and no-till systems; as well as to study the influence of depth of applied water on the fungigation efficiency. the fungicide epoxiconazol was applied on the bean crops, under conventional and no-till systems, by a center pivot system with different depths of applied water (3, 5 and 7 mm), and disease severity was evaluated for each test. the efficiency of the fungicide application by a conventional system (compression knapsack sprayer) was also evaluated. the results obtained allow us to affirm that the fungicide epoxiconazol, applied by a center pivot system, decreased the severity of bean angular leaf spot and bean alternaria leaf spot; and the depth of applied water by fungigation did not influence the efficacy of the fungicide epoxiconazol.

Abstract: As organiza es gerenciam o desempenho dos seus trabalhadores definindo metas e utilizando modernas ferramentas de planejamento, monitoramento e controle, como um esfor o para obter vantagens competitivas e sustentáveis. Para a efetividade desse sistema de administra o, a ciência aplicada tem se dedicado à produ o de instrumentos capazes de adequar individualmente as responsabilidades e os resultados pretendidos e assegurar os resultados. Ocorre que o ambiente corporativo é determinado por contingências de difícil identifica o, previsibilidade e gerenciamento. Esse esfor o pode ocorrer em contraposi o à resistência inconsciente dos indivíduos para atuar com a racionalidade esperada. A teoria freudiana (psicanálise) aparece como alternativa para a compreens o dos processos mentais de gênese inconsciente, que escapam à raz o e à vontade. As conclus es levaram em conta a rela o estreita, dialética, conflitiva e indissociável, entre o indivíduo e a organiza o.

Abstract: the role of intensive care specialists in the maintenance of deceased potential donors is not restricted to hemodynamics. appropriate endocrine-metabolic management is fundamental to maintaining energy support and hydroelectrolytic control, which cooperate for hemodynamic stability. hematological changes are also important, especially considering the issues caused by inappropriate transfusions. in addition, this article discusses the role of appropriate protective ventilation to prevent inflammatory responses and to provide more transplantable lungs. finally, judicious assessment of infections and antibiotic therapy is discussed

Abstract: O presente estudo tem por objetivo geral analisar o comportamento de compra de Papéis na Bovespa pelo investidor belo horizontino, a partir das mudan as no valor de sua riqueza financeira. A pesquisa caracteriza-se como exploratória, sendo que no aspecto da abordagem do problema, o trabalho foi desenvolvido em duas fases: uma qualitativa exploratória e outra quantitativa descritiva por meio da análise de variancia com aplica o do teste ANOVA. Investigaram-se os efeitos do framing positivo versus o framing negativo, na mensagem transmitida, através de textos que comp em o questionário respondido pelos entrevistados. O questionário foi aplicado a investidores mineiros composto por clientes de uma corretora de valores de Belo Horizonte, bem como professores da área de finan as que ministram disciplinas da área de mercado de capitais em universidades de Belo Horizonte. Neste estudo a maioria dos entrevistados do grupo framing positivo é do sexo masculino, com faixa etária acima de 40 anos. Demonstrou-se que a mensagem estruturada positivamente (enfatizando os ganhos da preven o ao risco) foi mais persuasiva do que a mensagem estruturada negativamente (enfatizando as perdas da n o preven o ao risco) e do que a mensagem informativa (do grupo controle). A hipótese de que a informa o positiva tem maior impacto do que a informa o negativa equivalente vai de encontro com as propriedades da fun o valor da Teoria dos Prospects. Conclui-se, portanto, que um determinado investidor, munido de informa es de caráter positivo, enfatizando os aspectos positivos da mensagem, sinta-se incentivado e superconfiante a investir em a es.

Abstract: the aim of this paper is to apply the reml/blup methodology in coffee breeding programs, using it in the parameter estimation and genotypic values prediction in a cultivar trial of coffea arabica. a trial established in selvíria-ms by unesp/campus de ilha solteira, was studied. the trial evaluated 12 cultivars developed by the instituto agron?mico de campinas in a complete block design with four replications and 10 plants per plot. the results showed a low genetic variability among cultivars for the traits height, stem diameter and number of primary branches, at age of 26 months. only the cultivars catuaí amarelo, icatu vermelho and catuaí vermelho showed predicted genotypic values for stem diameter superior to the general mean of the trait. the accuracy of the genotypic evaluation of the cultivars for stem diameter was, in average, 76%. the use of an experimental design with two plants per plot and 20 replications can lead to an accuracy of 90% for stem diameter. the mixed model methodology (reml/blup) showed to be adequate for genetic parameter estimation and genotypic values prediction in coffee breeding and then, could be used routinely.
