O uso do lúdico no ensino de química para deficientes visuais ou baixa visão: utilização da tabela FD14

Anais do II Seminário Seminário Estadual PIBID do Paraná: tecendo saberes / organizado por Dulcyene Maria Ribeiro e Catarina Costa Fernandes — Foz do Iguaçu: Unioeste; Unila, 2014A tabela Periódica organizada e elaborada com características puramente visuais como formato, distribuição, cor, símbolos, informações numéricas e propriedades com seguimentos distintos, acaba por excluir de uma vez o deficiente visual. A tabela FD14 ® apresenta uma proposta onde o aluno, poderá coletar todas as informações contidas em uma tabela periódica em formato de jogo, sendo a mesma, o principal instrumento na aprendizagem da química. O modelo de ferramenta proposto foi utilizado por um aluno do 1o ano do Ensino Médio de 15 anos, deficiente visual desde seu nascimento e inserido no Ensino Médio regular no Col. Est. Eurídes Brandão. Para êxito da proposta, “João” conseguiu identificar sem qualquer tipo de auxílio todas as informações que um aluno visual teria acesso, num processo realmente inclusiv

Agricultura conservacionista na produção familiar de mandioca e milho no Juruá, Estado do Acre: efeitos da adoção nos resultados de safras de 2006 a 2014.

As formas e as etapas atuais do uso do solo no Juruá, uma das regionais de desenvolvimento do Estado do Acre, não diferem do resto da Amazônia Brasileira. Envolvem o sistema de derruba e queima da floresta, tanto primária quanto secundária, o uso geral do solo em monocultivo e/ou em sucessão por períodos de até 5 anos com culturas exigentes em fertilidade do solo (arroz, feijão e milho nos dois primeiros anos) e depois com mandioca, menos exigente e tolerante à acidez do solo. Os resultados dos cultivos de mandioca e milho, apresentados neste comunicado técnico, são produtos de uma pesquisa conduzida em condições de campo, adotando-se princípios da agricultura conservacionista.bitstream/item/116756/1/25424.pd

Gene Expression Profiling during Early Acute Febrile Stage of Dengue Infection Can Predict the Disease Outcome

Background: We report the detailed development of biomarkers to predict the clinical outcome under dengue infection. Transcriptional signatures from purified peripheral blood mononuclear cells were derived from whole-genome gene-expression microarray data, validated by quantitative PCR and tested in independent samples. Methodology/Principal Findings: The study was performed on patients of a well-characterized dengue cohort from Recife, Brazil. The samples analyzed were collected prospectively from acute febrile dengue patients who evolved with different degrees of disease severity: classic dengue fever or dengue hemorrhagic fever (DHF) samples were compared with similar samples from other non-dengue febrile illnesses. The DHF samples were collected 2-3 days before the presentation of the plasma leakage symptoms. Differentially-expressed genes were selected by univariate statistical tests as well as multivariate classification techniques. The results showed that at early stages of dengue infection, the genes involved in effector mechanisms of innate immune response presented a weaker activation on patients who later developed hemorrhagic fever, whereas the genes involved in apoptosis were expressed in higher levels. Conclusions/Significance: Some of the gene expression signatures displayed estimated accuracy rates of more than 95%, indicating that expression profiling with these signatures may provide a useful means of DHF prognosis at early stages of infection. © 2009 Nascimento et al

BRS A705: an early-cycle, lodging-resistant irrigated rice cultivar with high yield.

BRS A705 is an early-maturing cultivar developed by Embrapa, recommended for irrigated cultivation. The plants have high tillering and moderate resistance to the main diseases. This cultivar has short stature, which confers a greater tolerance to lodging. It presents high yield and long and fine grains of excellent quality

Parasitoid Increases Survival of Its Pupae by Inducing Hosts to Fight Predators

Many true parasites and parasitoids modify the behaviour of their host, and these changes are thought to be to the benefit of the parasites. However, field tests of this hypothesis are scarce, and it is often unclear whether the host or the parasite profits from the behavioural changes, or even if parasitism is a cause or consequence of the behaviour. We show that braconid parasitoids (Glyptapanteles sp.) induce their caterpillar host (Thyrinteina leucocerae) to behave as a bodyguard of the parasitoid pupae. After parasitoid larvae exit from the host to pupate, the host stops feeding, remains close to the pupae, knocks off predators with violent head-swings, and dies before reaching adulthood. Unparasitized caterpillars do not show these behaviours. In the field, the presence of bodyguard hosts resulted in a two-fold reduction in mortality of parasitoid pupae. Hence, the behaviour appears to be parasitoid-induced and confers benefits exclusively to the parasitoid

A social and ecological assessment of tropical land uses at multiple scales: the Sustainable amazon network

Science has a critical role to play in guiding more sustainable development trajectories. Here, we present the Sustainable Amazon Network (Rede Amazônia Sustentável, RAS): a multidisciplinary research initiative involving more than 30 partner organizations working to assess both social and ecological dimensions of land-use sustainability in eastern Brazilian Amazonia. The research approach adopted by RAS offers three advantages for addressing land-use sustainability problems: (i) the collection of synchronized and co-located ecological and socioeconomic data across broad gradients of past and present human use; (ii) a nested sampling design to aid comparison of ecological and socioeconomic conditions associated with different land uses across local, landscape and regional scales; and (iii) a strong engagement with a wide variety of actors and non-research institutions. Here, we elaborate on these key features, and identify the ways in which RAS can help in highlighting those problems in most urgent need of attention, and in guiding improvements in land-use sustainability in Amazonia and elsewhere in the tropics. We also discuss some of the practical lessons, limitations and realities faced during the development of the RAS initiative so far
