Análise discursiva de blogs de professores: a produção da identidade na internet

This paper proposes a discursive analysis of teachers‘s blogs , particularly those accessible from the MEC site : http://portaldoprofessor.mec.gov.br/links.html . The aim is to analyze , dialogically, based on Bakhtinian discourse studies the speech of Portuguese language teachers on the internet , and to investigate aspects of the discourse genre blog , this specialized sphere of circulation :whether it is a means of exposing themselves, whether they are professional media extent , reflect about how to produce the identity of the Portuguese language teachers in such discourse . The axes of reflection on identity , in this case , are four: the subject‘sthe discourse about themselvesand their peers , how the subject shows itself tothe analyst - researcher in dialogue with others in history ( teachers , students , interested in issues of language , official documents ), how it can be seen by the analyst - researcher considering using resources ( videos , photos , literary genres, etc. ), how it is seen by those who comment your say

Short-term effect of alginate-biochar microbeads in corn germination

Biochar is the solid by-product of biomass pyrolysis. It is a promising soil conditioner and can be a material with high aggregate economic value, since its performance can improve plant’s nutrient utilization and reduce the usage of conventional fertilizers. Biochar can be used in the formulation of new types of fertilizers as polymeric microbeads. These microbeads can be enriched with biochar and nutrients in its matrix to form fertilizers of slow release of nutrients. Thus, as a promising agricultural material, it is important to assess the environmental hazards caused by the implementation of these microbeads. In this context, seeds were sown in a soil-less Petri dish with microbeads produced with biochar from sugarcane enriched with or without phosphate. The seeds germination and its vitality were evaluated by the first germination count (FGC) and the germination speed index (GSI). The short-term effects showed that the microbeads, in general, assessed by the means of FGC, GSI and mass gain showed the best performance, suggesting that the environment created by these materials provided the best chemical and physical interaction with the embryonic axes.

Abstract. Biochar is the solid by-product of biomass pyrolysis. It is a promising soil conditioner and can be a material with high aggregate economic value, since its performance can improve plant’s nutrient utilization and reduce the usage of conventional fertilizers. Biochar can be used in the formulation of new types of fertilizers as polymeric microbeads. These microbeads can be enriched with biochar and nutrients in its matrix to form fertilizers of slow release of nutrients. Thus, as a promising agricultural material, it is important to assess the environmental hazards caused by the implementation of these microbeads.

Effect of sodium hypochlorite under several formulations on root canal dentin microhardness

Aim The aim of the present study was to evaluate the effect of three different formulations of sodium hypochlorite on the microhardness of root canal dentin in cervical and apical segments. Methods Twenty-four extracted human teeth had their roots sectioned along their long axes in a buccolingual direction. One half of each root was selected, and transversely sectioned resulting in two segments, cervical and apical, with similar lengths. The specimens were divided into three groups (n = 16), according to the sodium hypochlorite formulation used: (a) group 1, 2.5% sodium hypochlorite; (b) group 2, Chlor-XTRA; and (c) group 3, 5.5% sodium hypochlorite gel. These groups were subdivided in two subgroups (n = 8): cervical and apical root segments. Before testing the substances, dentin microhardness was measured on each section, 100 μm from the root canal with a Knoop tester. After 15 min of application, a new measurement was performed on each segment. Data were collected and registered for statistical treatment. Results In both segments, the substances reduced dentin microhardness. No differences were observed between the groups, independent of the analyzed segment (P > 0.05). Conclusions All substances reduced dentin microhardness. Chlor-XTRA and 5.5% sodium hypochlorite gel promoted a reduction similar to the 2.5% sodium hypochlorite solution.

Representações sociais de professores sobre indisciplina no ensino médio e técnico

O objetivo do presente estudo foi identificar as representações sociais de professores sobre indisciplina em sala de aula. Adotamos a teoria das Representações Sociais como referencial teórico. Os dados foram coletados por meio de entrevistas individuais semiestruturadas. Os participantes foram três professores do ensino técnico, três do ensino médio e três de ambos os ensinos, totalizando nove docentes de uma Escola Técnica Estadual (ETEC) do interior paulista, pertencente ao Centro Estadual de Educação Tecnológica Paula Souza. Utilizando a análise de conteúdo, definimos três eixos temáticos: causas atribuídas à indisciplina, alternativas para lidar com a questão e concepção de indisciplina, para os quais caracterizamos categorias, em que obtivemos a frequência de respostas. Na análise dos resultados, podemos indicar que a representação social da indisciplina parece estar objetivada, principalmente, nas questões individuais dos alunos. Os professores relataram diferentes causas da indisciplina para os ensinos médio e técnico. Foram indicadas algumas diferenças na maneira de lidar com o aluno adolescente e adulto e entre as causas e as alternativas para lidar com a indisciplina. As representações sociais dos professores sobre a indisciplina ancoraram-se, em sua maioria, num referencial tradicional, associado à responsabilização do aluno e da família.

Hemangiossarcoma corneal em cão

Hemangiosarcoma is a malignant neoplasm and its corneal presentation is uncommon in the dog. The present work reports a case of primary corneal hemangiosarcoma on a mongrel female dog, 20kg, nine years old with a 2 month history of a mass with progressive growth in the right eye. The ophthalmic examination of the right eye showed blepharospasm, moderated conjunctival hyperemia and the presence of a reddish irregular nodule on the dorsal region of the cornea, occupying approximately 60% of the cornea. The ocular ultrasound revealed that the neoplasm affected only the cornea and the cytological examination diagnosed a malignant mesenchymal neoplasm. The patient was submitted to keratectomy followed by a third eyelid flap. The excised material was sent for histopathological analysis that diagnosed hemangiosarcoma. Fifteen days after surgery the third eyelid flap was removed and the ophthalmic examination revealed recurrence of the tumor, with the mass occupying the entire cornea and part of the bulbar conjunctiva. The patient was submitted to enucleation. No alterations were observed on the abdominal ultrasound and thoracic radiography, showing the primary characteristics of the disease. Two years after surgery the patient is clinically healthy, without any signs of recurrence or metastasis. Despite the surgical excision of the tumor with free margins, in cases of hemangiosarcoma with aggressive behavior, the enucleation should be considered as a viable option for a successfull therapeutic protocol and better prognosis of the patient.
