This paper describes the occurrence of cor triatriatum sinister, a rare cardiac malformation in dogs, associated with pulmonary edema and pulmonary hypertension in a 5-year-old Poodle female with history of acute dyspnea and cyanosis. The animal presented acute respiratory failure, heart failure with low cardiac output, progressing to acute tubular necrosis and death. The diagnosis was made posmortem due to the clinical instability of the dog. This malformation was diagnosed by the subdivision of the left atrium into two compartments separated by an abnormal fibromuscular membrane, absence of structural abnormalities of the mitral valve and thickening of pulmonary artery tunica media associated with renal tubular degeneration. The occurrence of cor triatriatum in dogs is most common in the right atrium, defined as cor triatriatum dexter. Additionally, pulmonary arterial hypertension associated with this malformation is described only in humans with this heart defect.

This research has been conducted with the objective of identifying the similarities and the differences between the school management system proposed by the government and the school management system applied on a daily basis by the school management team. This management team is composed by the school principal, the coordinator teacher, and the educational supervisor of a school in the inner state of Sao Paulo. Data is being collected researching the references already existed about the school management system, documents and files of the school, and by an interview with the management team. It is expected that this research will identify the close and the distant aspects between the evaluation of the management team about itself and the evaluation conducted by the school in the process of educational evaluations. The data obtained through this research job is being analyzed considering its quality aspects.

Solid-state compounds of general formula LnL3.nH2O, in wich Ln represents lanthanum, lanthanides and yttrium, L is ketoprofen, and n = 0,5 (Pr, Sm, Tb), 1 (La, Eu, Dy, Ho, Er, Tm, Lu) e 1,5 (Ce, Nd, Gd, Yb, Y) were synthesized. Simultaneous thermogravimetry-differential analysis (TG-DTA), differential scanning calorimetry (DSC), X-ray powder diffractometry, infrared spectroscopy and EDTA complexometry were employed to characterize these compounds. The TG-DTA and DSC curves provided information concerning the thermal behaviour and thermal decomposition of synthesized compounds. The experimental and theoretical infrared spectroscopic data suggested that ketoprofen acts as a bidentate ligand towards trivalent lanthanides and yttrium (III)

A utilização de programas computacionais específicos como ferramentas para análise estatística em identificação humana e de vínculos genéticos tem se tornado imprescindível, principalmente em casos de maior complexidade ou em grande escala. A análise de casos em que há genealogia incompleta gera resultados inconclusivos tornado os cálculos estatísticos mais laboriosos, consumindo tempo e pessoal qualificado. Os objetivos desse estudo são: o estudo simulado de casos reais de identificação humana e vínculos genéticos em situações especiais (meios irmãos na ausência dos pais, reconstrução), utilizando programas computacionais livres de cálculos estatísticos como ferramenta; a verificação do melhor programa livre de análise estatística disponível para utilização nos centros públicos brasileiros; e o levantamento estatístico dos casos reais brasileiros (vínculos genéticos, negatória, exclusão) para se obter uma visão da realidade brasileira em relação às suas relações familiares. Os principais métodos foram: análise das informações contidas nas fichas de registro e documentos anexados aos exames de vínculo genético dos participantes; e inserção nos softwares dos resultados de perfis genéticos obtidos de diferentes casos, de acordo com as especificações de uso. A amostra populacional dos casos analisados nesse trabalho incluiu 3.871 indivíduos. Em relação aos casos reais brasileiros, o exame de vínculo genético mais requisitado foi o de paternidade tipo trio; 68% dos casos incluíram o suposto pai como o pai biológico e 27% dos supostos pais estavam registrados na certidão de nascimento do filho e requisitaram o exame de paternidade para confirmá-la. A taxa de mutação encontrada variou de 0,4 a 2 x 10-3 per locus per gamete per generation. Após os estudos simulados... (Resumo completo, clicar acesso eletrônico abaixo)

The need for development of new materials is a natural process in the companies’ technological point of view, seeking improvements in materials and processes. Specifically, among the materials, ceramic exhibit valuable properties, especially the covalent ceramics which have excellent properties for applications which requires the abrasion resistance, hardness, high temperatures, resistence, etc. being a material that has applications in several areas. Most studies are related to improvement of properties, specially fracture toughness that allows the expansion of its application. Among the most promising ceramic materials are silicon nitride (Si3N4) which has excellent properties. The goal of this work was the development and caracterization of Si3N4-based ceramics, doped with yttrium oxide (Y2O3), rar earth concentrate (CTR2O3) and cerium oxide (CeO2) in the same proportion for the evaluation of properties. The powders' mixtures were homogenized, dried and compressed under pressure uniaxial and isostatic. Sintering was carried out in 1850 ⁰C under pressure of 0,1MPa N2 for 1 h with a heating rate of 25 ⁰C / min and cooling in the furnace inertia. The characterizations were performed using Archimedes principle to relative density, weight loss by measuring before and after sintering, phase analysis by X-ray diffraction, microstructure by scanning electron microscope (SEM), hardness and fracture toughness by the method Vickers indentation. The results obtained showed relative density of 97-98%, Vickers hardness 17 to 19 GPa, fracture toughness 5.6 to 6.8 MPa.m1/2, with phases varying from α-SiAlON and β-Si3N4 depending the types of additives used. The results are promising for tribological applications and can be defined according to the types of additives to be used

This article presents and analyzes the configuration of a project of university extension, developed in partnership with public schools, which has as themes sexuality and gender issues. We seek to understand to which extent sexuality and gender issues contributes to the continuity of the trio teaching / research / extension, while acting as promoter of knowledge of emancipation of those envolved (under graduates, faculty and the community). We based our presuppositions on action research, with document analysis and questionnaires responded to by participants in the project during the period 2005 to 2011 as the instrument of data collection. We constituted that formative processes that disrupt the predominant perspectives in the educational processes of a stereotypical, biologizing and heteronormative nature of sexuality and gender issues were favoured. Moreover, the experience of inseparability of teaching/research/extension was favoured, based on the understanding of knowledge as something constructed in and through social relations.
