Educação inclusiva: concepções de professores de ciências com relação à inclusão de alunos com deficiência visual em aulas de astronomia

Despite of intense discussion over recent decades about the inclusion of disabled people and the influence of conception of teachers about that inclusion for the effectuation of it, this work sought to identify conceptions of science teachers regarding the inclusion of students with visual impairment in the classes of astronomy providing basis for future studies.

Diagnóstico e gestão dos resíduos gerados em aterro sanitário

The issue of environmental impacts to human health and the generation and disposal of solid waste has led to a change of paradigms for your face, highlighting the need for sustainable management of municipal solid waste (MSW). In this context, the expansion of landfills in Brazil in recent decades makes it necessary to sustainable management of waste generated by this type of enterprise, since its implementation. The aim of this study was to perform a diagnosis of the generation of waste in a landfill, in the expansion phase, and the alternatives adopted for its management. The qualitative diagnosis was made from observations on site and the wastes were classified and quantified from August 2011 to January 2012. In the diagnosis was considered the reduction, reuse and recycle, in that order. The results of this study showed that the residue of the greatest generation was PEAD geomembranes used in the waterproofing of the landfill, reaching 7 t, followed by PVC pipes, which reached 850 kg, both destined for recycling. The largest volume of wastewater generated corresponded to the leachate, reaching 11,500 m3 , which were sent for treatment

Variation of soil and water volumes in riparian jungle soils of Brazil

The objective of this work is to study the relation between humidity, density, porosity and shrinkage of the floodplain soil and riparian vegetation and their ability to store water. For this purpose, two locations for every type of soils were evaluated. Both were placed at the Agronomy University (Faculdade de Ciências Agronômicas) in São Manuel, State of São Paulo, Brazil. The floodplain soil was vegetated with Southern Cattail (Typha domingensis). In both places, soil samples were collected from several depths: 0, 30, 60 and 100 cm. Results show that lower soil density values (0.15 g/cm3) with organic texture and high porosities values (up to 86.2%) were found in samples with the highest organic material content in the floodplain soil. For this field experiment, flood plains soils (characterised as basin gley soils) presented high volumetric instability with a retratibility of 67.49% and higher water storage capacities compared to riparian stands soils (characterised as fluvic neosoils).

Habilidades sociais e características pessoais em escolares de Belém

Este estudo relacionou a frequência da emissão de reação socialmente habilidosa, não-habilidosa passiva e não-habilidosa ativa às variáveis da criança (sexo, idade, condições clínicas). Participaram 57 meninos e 52 meninas, entre seis e 12 anos. O Questionário de Caracterização da Criança (QCC) levantou informações sobre sexo, idade e condições clínicas e o Inventário Multimídia de Habilidades Sociais de Crianças (IMHSC-Del Prette) avaliou as habilidades sociais, respondidos pelos cuidadores e escolares, respectivamente. Utilizou-se os testes U de Mann-Whitney, o coeficiente de correlação de Pearson e o teste t para análises dos dados. Os resultados indicaram: (a) diferenças significativas na adequação das reações habilidosas e não-habilidosas (p < 0,001); (b) aumento do repertório de habilidades sociais conforme o avançar dos anos (p < 0,001); e (c) meninas apresentaram mais frequência de habilidades sociais que meninos (p = 0,040). Não houve associações significativas entre habilidades sociais e condições clínicas (p = 0,539). Verificou-se que sexo e idade podem interferir na presença e desempenho de repertório socialmente habilidoso. Sugerem-se outras técnicas de avaliação que complementem os dados investigados e possibilitem intervenções futuras para amostras semelhantes.

Review of Good Growing: Why Organic Farming Works by Leslie A. Duram

As an extension vegetable specialist with a strong interest in organic farming and in assisting farmers to make a living, I relished this book. Leslie Duram is a geographer at Southern Illinois University Carbondale who has her roots in Kansas and is motivated by a love for Plains agriculture. The book, which she describes as a piece of advocacy scholarship, is at once scholarly, informative, and entertaining. In six well-organized chapters Duram provides an overview of organic farming within the context of overall U.S. agriculture and society (with our growing demand for organic food), reviews research describing organic farms and farmers , presents and analyzes the stories of five successful organic family farms, and offers a vision of a future American agriculture based on medium-sized organic family farms.

Geochemical signatures of metasedimentary rocks of high-pressure granulite facies and their relation with partial melting: Carvalhos Klippe, Southern Brasilia Belt, Brazil

High-grade metasedimentary rocks can preserve geochemical signatures of their sedimentary protolith if significant melt extraction did not occur. Retrograde reaction textures provide the main evidence for trapped melt in the rock fabrics. Carvalhos Klippe rocks in Southern Brasilia Orogen, Brazil, present a typical high-pressure granulite assemblage with evidence of mica breakdown partial melting (Ky + Grt + Kfs +/- Bt +/- Rt). The metamorphic peak temperatures obtained by Zr-in-Rt and ternary feldspar geothermometers are between 850 degrees C and 900 degrees C. The GASP bane peak pressure obtained using grossular rich garnet core is 16 kbar. Retrograde reaction textures in which the garnet crystals are partially to totally replaced by Bt + Qtz +/- Fsp intergrowths are very common in the Carvalhos Klippe rocks. These reactions are interpreted as a result of interactions between residual phases and trapped melt during the retrograde path. In the present study the geochemical signatures of three groups of Carvalhos Klippe metasedimentary rocks are analysed. Despite the high metamorphic grade these three groups show well-defined geochemical features and their REE patterns are similar to average compositions of post-Archean sedimentary rocks (PAAS, NASC). The high-pressure granulite facies Grt-Bt-Pl gneisses with immature arenite (wacke, arkose or lithic-arenite) geochemical signatures present in the Carvalhos Klippe are compared to similar rocks in amphibolite facies from the same tectonic framework (Andrelandia Nappe System). The similar geochemical signatures between Grt-Bt-Pl gneisses metamorphosed in high-pressure granulite facies and Grt-Bt-Pl-Qtz schists from the Andrelandia and Liberdade Nappes, with minimal to absent melting conditions, are suggestive of low rates of melt extraction in these high-grade rocks. The rocks with pelitic compositions most likely had higher melt extraction and even under such circumstances nevertheless tend to show REE patterns similar to average compositions of post-Archean sedimentary rocks (PAAS, NASC).

Analysis of expressed sequence tags from the agarophyte Gracilaria tenuistipitata (Rhodophyta)

A total of 3,631 expressed sequence tags (ESTs) were established from two size-selected cDNA libraries made from the tetrasporophytic phase of the agarophytic red alga Gracilaria tenuistipitata. The average sizes of the inserts in the two libraries were 1,600 bp and 600 bp, with an average length of the edited sequences of 850 bp. Clustering gave 2,387 assembled sequences with a redundancy of 53%. Of the ESTs, 65% had significant matches to sequences deposited in public databases, 11% to proteins without known function, and 35% were novel. The most represented ESTs were a Na/K-transporting ATPase, a hedgehog-like protein, a glycine dehydrogenase and an actin. Most of the identified genes were involved in primary metabolism and housekeeping. The largest functional group was thus genes involved in metabolism with 14% of the ESTs; other large functional categories included energy, transcription, and protein synthesis and destination. The codon usage was examined using a subset of the data, and the codon bias was found to be limited with all codon combinations used.
