The Temporomandibular Joint is a noble structure of the complex mandibular, a lot of research was conducted on the to signs and symptoms of the alterations that attack those structures. ln spite of the high incidence of the DTM in children, there's little knowledge about it, wich makes difficult the treatment Desorders Craniomandibulares (DCM) or Desorders Temporomandibulars (DTM). The Temporomandibular Joint is composed basically by three elements: bones, muscles and disk, in relation to bony part, we have the fossae mandibular that is part of the temporary bone and wich houses the condyle mandibular, accomplishing the articulation among the cranium and the jaw (it leaves piece of furniture of the articulation). Our intention in that work was of verifying a possible asymmetry of the fossae mandibular on the left side and of the right side in relation to two straight line: a straight line that coincided with the plane medium sagittal and another perpendicular straight line to the plan medium sagittal. Analyzing, the fossae mandibular in 91 dry craniums of children, with age varying between four months of life intrauterina and five years, in x-rays in that the incidence was cranium-flow, we could end that: in spite of we find statistical significance in relation to that asymmetry, clinic cannot affirm that interferences on occlusion exists for that asymmetry

The need for affordable housing and the high cost of today's building materials make necessary to look for useful and affordable technologies for these house buildings. In this context, this study aimed to evaluate the technical and economic feasibility of construction technology called Earthbag for use in public housing. Technical assessments were based on Kiffmeyer and Hunter's book (2004), academics dissertations and construction standards for the technology. The result allowed a positive evaluation towards the feasibility proposal and showing the possibility of replace the use of structural concrete blocks in public housing. The economic viability was performed an economical compared to a project Housing Project Bom Retiro 2 with one of Earthbag which have been shown considerable savings between the techniques. For the construction of masonry, build with purchased sand, 13% lower budget was found in comparison of a concrete masonry block. With the use of sand from the work site itself, there is a saving of 18%. Although earthbag has proven to be a technically and economically feasible for application in the construction of affordable housing, the shortage of technical and scientific studies and Brazilian regulations on this technology has limited its large-scale use

Este trabalho abordou o resfriamento rápido com ar forçado de morango via simulação numérica. Para tanto, foi empregado o modelo matemático que descreve o processo de transferência de calor, com base na lei de Fourier, escrito em coordenadas esféricas e simplificado para descrever o processo unidimensional. A resolução da equação expressa pelo modelo matemático deu-se por meio da implementação de um algoritmo, fundamentado no esquema explícito do método numérico das diferenças finitas, executado no ambiente de computação científica MATLAB 6.1. A validação do modelo matemático foi realizada a partir da comparação de dados teóricos com dados obtidos num experimento, no qual morangos foram resfriados com ar forçado. Os resultados mostraram que esse tipo de investigação para a determinação do coeficiente de transferência de calor por convecção é promissora como ferramenta no suporte à decisão do uso ou desenvolvimento de equipamentos na área de resfriamento rápido de frutos esféricos com ar forçado.
