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 posses...
Many investigations have recently been performed on return vent height and indicate that having 1.3 m distance from the floor is the optimized height for it. In this article, the effect of distance between opening diffuser and return vent on air quality, thermal comfort and energy saving was investigated. According to the results, by increasing the distance between opening and return vent up to...
Sakarya River, which is the largest river in northwest Anatolia, drains waters from a large area known as Middle Plateau. The most striking geomorphological features of and its tributaries this area, are joining gorges connect basins terrace systems together. This study aims to reveal morphometric sedimentological between Inhisar, Gemiciköy settlements. has settled region Upper Pliocene, formed...
In most cases, structural engineers assume a concrete floor to be a rigid diaphragm. Although this simplification is in most cases acceptable, it should be noted that such an assumption may be distrusted due to certain problems. Concrete structures with staggered shear walls are among those whose analysis should be conducted with special concern for the behavior of their floor diaphragms. Howev...
The relative rates of erosion by rivers and glaciers, and the topographic effects of these two different styles of erosion, remain outstanding problems in geomorphology. We use a quantitative description of local fluvial landscapes to estimate how glaciated landscapes might look now had glaciers not developed. This indicates the landscape modification attributable to glacial erosion. We present...
[1] The morphologic transition from complex impact craters, to peak-ring basins, and to multi-ring basins has been well-documented for decades. Less clear has been the morphometric characteristics of these landforms due to their large size and the lack of global high-resolution topography data. We use data from the Lunar Orbiter Laser Altimeter (LOLA) instrument onboard the Lunar Reconnaissance...
Background and Aim: Agricultural combine harvesters play a crucial role in cereal productions. A combine operator performs almost all harvesting activities in seated posture. As an interface of the biomechanical system of operator’s body and combines’ mechanical system, seat has major effect on operator’s safety, health, and comfort. A successful design of seat is not achievable without conside...
The Kan-Soleghan basin is located on the southern Hillside of the Alborz, which has affected the Alp-Himalayan active zone over time. In this respect, the evaluation of active tectonic processes and their effects on many human activities, such as the design and construction of cities, powerhouse, dams, industrial facilities are of great importance. The passage of the Tehran-North Freeway Tunnel...
OBJECTIVE To investigate the maxillary and mandibular anterior crown width/height ratio and its relation to various arch perimeters, arch length, and arch width (intercanine, interpremolar, and intermolar) groups. MATERIALS AND METHODS The calculated sample size was 128 subjects. The crown width/height, arch length, arch perimeter, and arch width of the maxilla and mandible were obtained via ...
