Análise Prosódica de segmentações não-convecionais de palavras em textos do sexto ano do EF

This paper analyzes unconventional segmentation of word found in texts of the sixth grade of Elementary School. Through quantitative and qualitative analysis, we describe the prosodic characteristics that may be motivated the hyper and hippossegmentation of words found in 27,4% of 606 investigated texts. We identified a tendency toward a more text with hippossegmentation than hypersegmentation, characteristic similar to what is reported about children’s text. Taking into account the theoretical framework of Prosodic Phonology, we argue about the relevance of prosodic word and clitic group in the description of the regularities observed in data of unconventional segmentation of word. We note that (i) in cases of hipposegmentation, it predominates the hollow of a clitic followed by a phonological word, (ii) in cases of hypersegmentation, it predominates a segmentation of a prosodic word into a clitic group. We present evidences to be the spelling of clitic elements a challenge to students analyzed. By investigating in the grammatical class that owned the clitics spelled unconventionally, we verified that they are prepositions (“em, de, com”) and pronouns (“me, lhe, lo”), a characteristic that particularize these data in relation to data from students in the early stage of language acquisition.

Práticas de leitura e escrita em contexto acadêmico: relações (hiper)textuais singulares

The present article aims at reflecting about the discursive practices of writing and reading on the net, more specifically about the writing and reading methods used by the undergraduate and graduated teachers, based on an internet search engine. It’s of interest to investigate: i) the (hyper) textual relations established in the context thought as permitted by the electronic resources; ii) the discursive marks that arise (are arisen) in a singular way of reading (and/or writing). The set of material was produced during a university extension course about reading and cyberspace, whose context consisted of a drawing production of the reading process on an internet search engine, on the basis of the signifier “apple”. Based on the French Discourse Analysis and assumptions from the New Literacy Studies, we intended to discuss the operating procedures of the internet search and the effects of meanings produced by the subject during his/her reading/writing process.

Partial purification, immobilization and preliminary biochemical characterization of lipases from Rhizomucor pusillus

Lipases have important applications in biotechnological processes, motivating us to produce, purify, immobilize and perform a biochemical characterization of the lipase from Rhizomucor pusillus. The fungus was cultivated by solid state fermentation producing lipolytic activity of about 0.5 U/mL(4U/g). A partial purification by gel filtration chromatography in Se-phacryl S-100 allowed obtaining a yield of about 85% and a purification factor of 5.7. Our results revealed that the purified enzyme is very stable with some significant differences in its properties when compared to crude extract. The crude enzyme extract has an optimum pH and temperature of 7.5 ° C and 40 ° C, respectively. After purification, a shift of the optimum pH from 7 to 8 was observed, as well as a rise in optimumtemperature to 60 ° C and an increase in stability. The enzyme was immobilized on CNBr-Agarose and Octyl-Agarose supports, having the highest immobilization yield of 94% in the second resin. The major advantage of immobilization in hydrophobic media such as Octyl is in its hyper activation, which in this case was over 200%, a very interesting finding. Another advantage of this type of immobilization is the possibility of using the derivatives in biotechnological applications, such as in oil enriched with omega-3 as the results obtained in this study display the hydrolysis of 40% EPA and 7% DHA from sardine oil, promising results compared to the literature.

Tratamento da classe II hiperdivergente com o aparelho extra bucal de Thurow modificado

Objectives: natural dentofacial changes and that induced by the Thurow modified extra oral appliance (TMEOA) were evaluated in this prospective study. Methodology: the data consisted of fifteen Class II division 1 children 7 to 10 years old, with anterior open bite and hiperdivergent facial pattern treated with the Thurow appliance and of fifteen Class II division 1 children followed longitudinally from 6 to 12 years of age without treatment (Burlington Growth Centre, Toronto University, Canada). The analyses were based in traditional measurements obtained in lateral cephalometric radiographs scanned with the aid of the software Radiocef Studio®. Radiographs were taken in the beginning and after 1 year of treatment for the treated group and at the 6, 9 and 12 years of age for the control group. Results: the data analysis showed that the TMEOA significantly reduced the SNA, ANB, AOBO, SNPOc SNPM, SGO/NMe, OJ e OB. On the other hand the appliance did not interfere with the SNB e SNPP. The natural growth promoted significant change in the ANB, AOBO, SNPOc, OJ e OB from 6 to 9 years and in the SNB, SNPOc e SGo/NMe from 9 to 12 years. The restriction of the maxillary growth (SNA), reduction of the skeletal discrepancy (ANB) and the reduction of the overjet (OJ) were significant with the treatment considering the natural growth as verified in the control group. Conclusion: the TMEOA corrected the skeletal Class II malocclusion by maxillary restriction, reducing the overjet, closing the anterior open bite and decreasing both the hyper divergent facial pattern and mandible plane inclination.

O teatro do oprimido como ferramenta psicoeducativa

This article is a theoretical and practical portrait of a non-formal educational activities aimed to examine the transformations experienced by young people in a state of social vulnerability participating in social discussions in a form of theater of the oppressed - the theater-forum. The technique of theater-forum was held as a methodology able to establish a critical space action / reflection / action on the social reality experienced by these young people. The discussions postulates in some theatrical performances were analyzed critically and scored from theoretical frameworks of contemporary thinkers (Bauman, Augé, Boal) and analysts sociohistorical (Bock, Aguiar, Ozella). We conclude that this action re-signified social problems (violence, drug involvement, hyper-consumerism, poverty, cultural capital etc.) among these young people. In general, the young through a collective construction could experience new processes of subjectivity and open to possible changes and social transformations criticism in your life.

In silico infrared and Raman spectroscopy under pressure: The case of CaSnO3 perovskite

The CaSnO3 perovskite is investigated under geochemical pressure, up to 25 GPa, by means of periodic ab initio calculations performed at B3LYP level with local Gaussian-type orbital basis sets. Structural, elastic, and spectroscopic (phonon wave-numbers, infrared and Raman intensities) properties are fully characterized and discussed. The evolution of the Raman spectrum of CaSnO3 under pressure is reported to remarkably agree with a recent experimental determination [J. Kung, Y. J. Lin, and C. M. Lin, J. Chem. Phys. 135, 224507 (2011)] as regards both wave-number shifts and intensity changes. All phonon modes are symmetry-labeled and bands assigned. The single-crystal total spectrum is symmetry-decomposed into the six directional spectra related to the components of the polarizability tensor. The infrared spectrum at increasing pressure is reported for the first time and its main features discussed. All calculations are performed using the CRYSTAL14 program, taking advantage of the new implementation of analytical infrared and Raman intensities for crystalline materials.

Amorphous ZrF4-a molecular dynamics study

Using an effective two-body interaction potential, a molecular dynamics study of the structural properties of amorphous ZrF4 phase is presented. The effective pair potential includes steric repulsion, Coulomb interaction due to charge transfer, and charge-dipole interaction due to the large electronic polarizability of anions. The results for structural correlations, such as pair distribution functions, coordination numbers, and bond angle distributions are presented. Excellent agreement is obtained by comparing experimental X-ray diffraction and the simulated static X-ray structure factor. © 1993.

Indicadores diagnósticos da síndrome metabólica, butirilcolinesterase e estado de condicionamento físico em adolescentes obesos e eutróficos: uma breve explanação do atual estado da arte

Damage to health caused by excess body fat also generating a negative economic impact, with significant increase in public spending. The metabolic syndrome, which also gets several other names, such as plurimetabolic syndrome or syndrome X, is nothing more than the combined incidence of some diseases or metabolic disorders in which obesity, besides being one of them, seems to promote parallel effects that contribute to the development of other chronic diseases such as diabetes and cardiovascular disease. Researchers agree that hyper caloric diets associated with a sedentary lifestyle are the main triggers of disease, including the increasing on genetic predisposition to this disease in children and adolescents. In the case of children and adolescents the diagnosis is complicated by the lack of a consensus accepted by the scientific community. In addition to behavioral and environmental factors unfavorable to health, in a more detailed analysis also found hereditary aspects or simply genetic, such as hepatic enzyme Butyrylcholinesterase. When compared to eutrophic, obese adolescents, like adults obese, have higher serum concentration values as well as major activity for this enzyme. Increasing evidence suggests that excess body weight assumes an important role in the variation of metabolic functions in adolescents, favoring the emergence of early diagnostic indicators of metabolic syndrome.
