INTRODUCTION The existent classifications of congenital scoliosis cannot contain all the cases encountered in the medical practice taking into account the complexity of the spine deformity in this pathology. PURPOSE The paper represents a retrospective study that analyses a new classification of congenital scoliosis in comparison with the existing classification. MATERIALS AND METHOD This s...

introduction recently, employment of rotary tillers has been expanded in gardens and small farms, especially in the northern of iran. however using the l-shaped blades in the conventional rotary tillers have some problems such as severe vibration problems, weeds stucking around the blades, forming the plow pan and lower performance due to the less powers of such small rototillers. therefore in ...

How asymmetries in motor behavior become established normally or atypically in mammals remains unclear. An established model for motor asymmetry that is conserved across mammals can be obtained by experimentally inducing asymmetric striatal dopamine activity. However, the factors that can cause motor asymmetries in the absence of experimental manipulations to the brain remain unknown. Here, we ...

Many physically-based distributed models study the landslide occurrence using an infinite slope stability analysis, simulating a planar failure, which is not usually applicable to rotational failures and deep landslides. Recently, some three-dimensional have been developed that applied in different parts of world. In this research, Scoops3D model implemented for susceptibility analysis tropical...

In the Northridge and Kobe earthquakes, brittle failure of welded beam-to-column connections was observed in steel structures. So, bolted were considered as an alternative to these kinds connections. Extended end-plate con-nection is one most commonly used structure. this article, behavior sloped extended studied. Finite element method investigate connection by ABAQUS software. The main aim stu...

An experimental and computational study of the bending response of steel sandwich panels with corrugated cores in both transverse and longitudinal loading orientations has been performed. Panel designs were chosen on the basis of failure mechanism maps, constructed using analytic models for failure initiation. The assessment affirms that the analytic models provide accurate predictions when fai...

third molar eruption is an unpredictable event. occasionally, mandibular third molars undergo angular changes in young adults. this rotational drift is of unknown etiology, is not predictable and may facilitate the eruption or may make the impaction worse. a rare case is presented with severe rotational drift of a mesioangularly impacted mandibular third molar.
