O uso de “temas geradores” como metodologia, teve sua escolha considerando as possibilidades para familiarizar o contexto social, da comunidade e da região do aluno e seus conhecimentos ao ensino de Ciências/Química. A aplicação da proposta demonstrou, em seus resultados, que ao relacionar os saberes escolares com os saberes populares, os assuntos de química estudados puderam ser abordados de maneira mais motivadora, sendo observado uma grande participação dos estudantes, bem como, contribuiu para desenvolver no educando uma interpretação mais crítica acerca das questões atuais
A obtenção artesanal do Tucupi: Saberes Populares e o Ensino de Química
Este trabalho tem por base os estudos de CHASSOT (2008), GONDIM E MÓL (2008), em que buscou-se introduzir os saberes populares na escola, fazendo deles saberes escolares. A proposta foi realizada com alunos do 1° ano do ensino médio, através de uma oficina temática que se desenvolveu com a aplicação de questionário para verificar os conhecimentos prévios dos alunos e inserir a problemática do estudo (possível ação venenosa da mandioca). Em seguida, houve a intervenção abordando o método artesanal de produção do tucupi relacionado ao conceito de separação de misturas e formação do ácido cianídrico (HCN). Através de um questionário final, fez-se a coleta do conhecimento adquirido pelos alunos. Observou-se que a oficina serviu para mediar o conhecimento químico ao cotidiano e promoveu o aprendizado e a valorização do conhecimento popular a partir da inter-relação deste ao conhecimento científico. Os alunos mostraram resultados significativos de aprendizado e satisfação perante a proposta
Maternal anemia and birth weight : a prospective cohort study
Objective
To investigate the association between maternal anemia and low/insufficient birth weight.
Design A prospective cohort study of pregnant women who underwent prenatal care at the healthcare
units in a municipality of northeast Brazil together with their newborn infants was carried
out. The pregnant women were classified as having anemia when the hemoglobin level
was below 11 g/dl. Infants who were born full term weighing less than 2500 grams were classified
as low birth weight, and those weighing between 2500 and 2999 grams were classified
as insufficient weight. The occurrence of maternal anemia and its association with birth
weight was verified using crude and adjusted Relative Risk (RR) estimates with their corresponding
95% confidence intervals (95%CIs). Results
The final sample was comprised of 622 women. Maternal anemia was considered a risk factor
for low/insufficient birth weight, after adjusting the effect measurement for maternal age,
family income, urinary infection, parity, alcoholic beverage consumption during pregnancy
and gestational body mass index: RRadjusted = 1.38 [95% CI: 1.07 to 1.77].
Conclusions Maternal anemia was associated with low/insufficient birth weight, representing a risk factor
for the gestational outcomes studied
Pervasive gaps in Amazonian ecological research
Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4
While the increasing availability of global databases on ecological communities has advanced our knowledge
of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In
the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of
Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus
crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced
environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian
Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by
2050. This means that unless we take immediate action, we will not be able to establish their current status,
much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Selección de genotipos de batata-doce Ipomoea Patatas (l.) Lam. Con características para el consumo de mesa
A batata-doce é um alimento, que possui uma grande variabilidade genética, no qual pode ser selecionadas para algumas finalidades como, por exemplo: maior resistência a pragas e doenças. Pesquisadores da Universidade Federal do Tocantins -UFT- vem realizando desde 1997, estudos com batata-doce, destinada a produção de etanol. Desde então vem sendo realizados melhoramento genético entre genótipos com o intuito de melhorar a produção do biocombustível. Entretanto, existem genótipos com características desejáveis ao consumo humano. Diante disso, o objetivo deste trabalho foi avaliar alguns desses genótipos, com intuito de encontrar características adequadas para mesa. As análises realizadas foram: formato, resistência a insetos, cor de casca e cor de polpa. Foram avaliadas 30 cultivares, nas quais duas morreram. As cultivares HSF 0506 e BDI 2011-52 apresentaram bom formato de raiz (nota 1). As cultivares BDI 2011-52 (nota 1,11) e HSF 0506 (nota 1,33) se destacaram com melhores notas em resistência a insetos. A cor predominante de casca e polpa foi branca (64%) e creme (71%), respectivamente. Segundo os dados avaliados, conclui-se que a cultivar HSF 0506 se mostrou superior às outras, atendendo os padrões de mesa solicitados pelo consumidor.

Sweet potato is a food that has a great genetic variability, in which it can be selected for some purposes such as: greater resistance to pests and diseases. Researchers at the Federal University of Tocantins (UFT) have been conducting studies with sweet potatoes since 1997 to produce ethanol. Since then, genetic improvement between genotypes has been carried out in order to improve biofuel production. However, there are genotypes with characteristics desirable for human consumption. Therefore, the objective of this work was to evaluate some of these genotypes, in order to find suitable table characteristics. The analyzes were: size, insect resistance, bark color and pulp color. Thirty cultivars were evaluated, in which two died. The cultivars HSF 0506 and BDI 2011-52 presented good root format (note 1). The cultivars BDI 2011-52 (note 1.11) and HSF 0506 (note 1.33) stood out with better notes on insect resistance. The predominant color of bark and pulp was white (64%) and cream (71%), respectively. According to the data evaluated, it was concluded that the cultivar HSF 0506 was superior to the others, taking into account the table standards requested by the consumer.
Key words: Sweet potato table patterns; Genetical enhancement.

Neotropical freshwater fisheries : A dataset of occurrence and abundance of freshwater fishes in the Neotropics
The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.
