introduction: comparison of the relationships and distance between maxillary root tips and   the maxillary sinus floor using oral panoramic in the dolichocephalic and brachycephalic compared to mesocephalic individuals. methods: oral panoramic images from 300 individuals were analyzed and the relationships and distance between the maxillary root tips and the sinus floor was assessed by qualitat...

In this study, heat transfer and aerosol deposition in the under-floor and baseboard heating systems have been investigated, numerically. The aim of this study is a comparison between these heating systems. This comparison obtains the optimal heating system with low suspended particles in the air. Computational fluid dynamic with Eulerian-Lagrangian method has been used to simulate fluid and pa...

In order to study the basic mechanical property of cast-in-place stiffening-ribbed-hollow-pipe reinforced concrete girderless floor, and similarities and differences of the structural performance compared with traditional floor, we carried out the destructive stage loading test on the short-term load test of floor model with four clamped edges supported in large scale, and conducted the long-te...

Experience in the design of steel and concrete floor systems to control vibrations suggests that a floor system’s vibration characteristics are often fundamental to its acceptable performance. In such cases, serviceability drives the design instead of strength. This is particularly true for laboratory floors that support sensitive equipment and floor girders that fall within certain spans. This...

In order to study the basic mechanical property of the new honeycombed-core girderless floor in cast-in-place reinforced concrete, and similarities and differences of the structural performance compared with traditional floor, we carried out the destructive stage loading test on large-scale corner columns supported reinforced concrete honeycombed-core girderless floor. And the thesis conducted ...

this paper deals with an inspection of defects including corrosion and leakage by acoustic emission (ae) in an oil tank floor. in contrast to intrusive methods such as magnetic flux leakage, eddy current or ultrasonic, there is no need to emptying and entering the tank in ae method in order to inspection. in this research ae investigation and ae source location is presented in detail. the resul...

introduction: cleft lip (cl) and cleft palate (cp) are among the most common congenital anomalies. constituting 65% of head and neck anomalies in isolated or syndromic forms, they are considered as the most common head and neck congenital deformities in children. methods: 15 children from the tabriz children hospital were evaluated in this descriptive-analytic cross sectional study that possess...
