O cisto dentígero, também conhecido como folicular, origina-se a partir do acúmulo de líquido entre o epitélio reduzido órgão esmalte e coroa dentária, que resulta na separação folículo circunda um dente não erupcionado. Geralmente são radiolúcidos uniloculares. objetivo trabalho foi relatar caso dentígero associado terceiro molar inferior impactado provocando reabsorção radicular externa prime...

in this study, a computational fluid dynamics (cfd) model was developed to evaluate ultraviolet disinfection applesauce reactor. to simulate uv reactors, three sets of equations, including hydrodynamics, radiation and species mass conservation were solved simultaneously. the realizable k-e turbulence model and the discrete ordinate method were used to find the uv radiation profile through the r...

increasing the thermal stability and resistance to bacterial attack (bioresistance) of the potato starch used in the water-based drilling fluid is the aim of this work. four types of potato starch grafted with acrylamide and a mixture of each one with acrylic acid, 2-acrylamido-2-methyl-1-propane sulfuric acid and itaconic acid were synthesized by manganese (iv)-induced redox system at the suit...

a pressurized fluid extraction (pfe) method for the extraction of pistachio oil was developed using a modified supercritical fluid extractor. the supercritical fluid extraction apparatus was modified to be able to pump liquid solvent and co2 into the extraction vessel alternatively. the experimental results showed that the extraction yield was independent of the extraction pressure. it was also...

treatment of hydrocephalus in posterior fossa tumors in children is still a matter of controversy and different centers have their own routines. in this regard, hospital records of all children with posterior fossa tumors treated in our center during the interval of 1985-1995 were reviewed. patients’ demographic and diagnostic data were analyzed and the frequencies of shunting procedures were d...
