Paniculite mesentérica: aspectos na tomografia computadorizada
Moreira Luiza Beatriz Melo,Pinheiro Ricardo Andrade,Melo Alessandro Severo Alves de,Alves José Ricardo Duarte
Radiologia Brasileira , 2001,
Abstract: A paniculite mesentérica é um processo inflamatório que constitui o segundo estádio de uma doen a rara e progressiva que envolve o tecido adiposo do mesentério. Entre os métodos radiológicos utilizados no diagnóstico est o os estudos baritados, a ultra-sonografia, a tomografia computadorizada e a ressonancia magnética do abdome. A tomografia computadorizada tem importancia tanto no diagnóstico e avalia o da extens o da doen a quanto no planejamento do tratamento, e os aspectos tomográficos variam de acordo com o estádio da doen a e se o componente predominante é inflamatório ou fibroso, tendo boa correla o com os achados da anatomopatologia. Os autores estudaram dez casos de paniculite mesentérica submetidos a tomografia computadorizada, sendo que em um deles foi realizada ressonancia magnética. Em todos os casos o aspecto tomográfico era o de forma o expansiva heterogênea, com densidade predominantemente adiposa, apresentando vasos ectasiados e bandas lineares com densidade de partes moles de permeio, localizada no mesentério.

Abstract: mesenteric panniculitis is an inflammatory process that represents the second stage of a rare progressive disease involving the adipose tissue of the mesentery. imaging methods used in the diagnosis of mesenteric panniculitis include barium studies, ultrasonography, computed tomography and magnetic resonance imaging. computed tomography is important for both, diagnosis and evaluation of the extension of the disease and treatment monitoring. computed tomography findings may vary according to the stage of the disease and the amount of inflammatory material or fibrosis. there is also good correlation between the computed tomography and anatomical pathology findings. the authors studied 10 patients with mesenteric panniculitis submitted to computed tomography. magnetic resonance imaging was also performed in one patient. in all patients, computed tomography revealed a heterogeneous mass in the mesentery with density of fat, interspersed with areas of soft tissue density and dilated vessels.

Abstract: the effects of ultrasound stimulation on bone healing have been demonstrated in experimental and clinical studies. the purpose of this study was to investigate the clinical application of low-intensity pulsed ultrasound as an adjuvant for the treatment of diaphyseal fractures in dogs. sixteen dogs of different breeds, ages ranging from seven months to six years, weighing from 2.5 to 43kg, were enrolled in the study. all dogs presented fresh closed diaphyseal fractures in the radius and ulna, femur or tibia and fibula stabilized with osteosynthesis techniques (intramedullary pinning, external skeletal fixation or the combination of both). the dogs were divided into two groups: stabilized fractures treated by low-intensity ultrasound (treatment group, n=8); stabilized fractures not treated by ultrasound stimulation (control group, n=8). the animals were assessed by means of clinical examination and radiographic studies in the preoperative period, immediate postoperative period, and every 30 days after the surgical procedures. the treatment was performed using stationary low-intensity (30mw cm-2) pulsed ultrasound (sine wave signal of 1.5mhz frequency, 200μs pulse width and 1khz repetition frequency) on the fracture site. ultrasound therapy was carried out 20 minute per day, for 21 consecutive days, starting between the 1st and the 9th postoperative day. the student?s t test was used for the statistical analysis and showed a significant difference (p<0.001 and a=0.05) between the mean time for bone healing of the animals in the treatment group (mean of 67.5 days) and that of animals in the control group (mean of 106 days). this protocol of ultrasound stimulation promoted clinical and radiographic signs of bone healing acceleration in the treated fractures. the results of this study suggest that low-intensity pulsed ultrasound may be indicated as an adjuvant therapy in fresh diaphyseal fractures in dogs.

Abstract: Important in many different sectors of the industry, the determination of stream velocity has become more and more important due to measurements precision necessity, in order to determine the right production rates, determine the volumetric production of undesired fluid, establish automated controls based on these measurements avoiding over-flooding or over-production, guaranteeing accurate predictive maintenance, etc. Difficulties being faced have been the determination of the velocity of specific fluids embedded in some others, for example, determining the gas bubbles stream velocity flowing throughout liquid fluid phase. Although different and already applicable methods have been researched and already implemented within the industry, a non-intrusive automated way of providing those stream velocities has its importance, and may have a huge impact in projects budget. Knowing the importance of its determination, this developed script uses a methodology of breaking-down real-time videos media into frame images, analyzing by pixel correlations possible superposition matches for further gas bubbles stream velocity estimation. In raw sense, the script bases itself in functions and procedures already available in MatLab, which can be used for image processing and treatments, allowing the methodology to be implemented. Its accuracy after the running test was of around 97% (ninety-seven percent); the raw source code with comments had almost 3000 (three thousand) characters; and the hardware placed for running the code was an Intel Core Duo 2.13 [Ghz] and 2 [Gb] RAM memory capable workstation. Even showing good results, it could be stated that just the end point correlations were actually getting to the final solution. So that, making use of self-learning functions or neural network, one could surely enhance the capability of the application to be run in real-time without getting exhaust by iterative loops.

Abstract: in this research, we investigated the changes experienced by a community affected by the construction of a hydroelectric on the paraná river. ethnography procedures were used to conduct several visits to the community resettled in a planned and built village to replace the old one which was submerged. we established contacts with older residents and produced with them hold dialogues in various situations such as visits to their own houses and circle chats that took place on sidewalks. in their own words the riparian people perceived the area changes as something negative in all plans of life. they resent the river's loss, the plenty of fishing, the hunting held in the forests, the fertile land cultivated in the ravines, the sociality and all the production of subjectivity that they used to maintain in that place marked by the proximity with the river and its waters.
Impactos da constru o de usinas hidrelétricas na vida de ribeirinhos (Impacts of the construction of hydroelectric power stations in the life of the riparian population)

Revista Emancipa??o , 2009,
Abstract: Resumo: Neste trabalho, examinaremos o impacto devastador da moderniza o orientada pela expans o do capitalismo numa comunidade localizada às margens do rio Paraná. Tal impacto foi gerado por duas grandes obras: a constru o de uma ponte sobre o rio e a constru o de uma usina hidrelétrica que formou um grande lago e submergiu a vila. A popula o foi transferida para um núcleo urbano, planejado e construído como indeniza o pela submers o do antigo povoamento. A cria o do lago e a mudan a para a nova cidade modificaram profundamente a vida da comunidade. A pesca, o plantio nas terras férteis das margens do rio e a olaria que utilizava a farta argila sofreram um golpe profundo, afetando a atividade econ mica e todo o modo de vida da popula o local. A interven o modernizadora, em nome do progresso, destruiu uma comunidade e uma cultura que tinham o rio como referência principal. Abstract: This paper aims at examining the impact of the modernization orientated by the expansion of capitalism in a community located alongside the Paraná River. This impact was produced by two large works: the construction of a bridge and the construction of a hydroelectric station, which formed a big lake that submerged the village. The population was transferred to an urban site planned and built as reparation for the submersion of the previous settlement. The creation of the lake and the transference to the new city deeply modifi ed the life of the community. Activities such as fi shing, planting in the fertile lands of the river’s banks and the pottery that used its abundant clay suffered a hard blow, which affected the economical activity and the whole way of life of the local population. In the name of progress, the modernizing intervention destroyed a community and a culture that had the river as its main reference.
