OBJECTIVE To validate intra- and inter-class correlation coefficients of a transparent 3D-TC protocol and investigate relationships between different axial rotations. METHODS Twenty unilateral knee TCs (iSite - Philips) were evaluated by means of a transparent 3D-TC OsiriX Imaging Software (v.3.9.4), 3D MPR protocol. Mathematical model of femoral tunnel projections acquired on vertical and ho...

The genus Hypericum is one of the most important medicinal plants that contain 17 species in Iran, three of them are endemics. This paper reports the essential oil composition of eight Hypericum species from Iran. The essential oil analysis of a number of the studied plants has already been reported but their report from Iran may be valuable for scientists.  Samples collected from different pla...

The galactic dynamo effect due to Parker-shearing instability of magnetic flux tubes II. Numerical simulations and the nonlinear evolution. Abstract. In this paper we continue investigations of the Parker-shearing instability performing numerical simulations of the magnetic flux tube dynamics in the thin flux-tube approximation. We show that evolution of flux tubes resulting from numerical simu...

any defects in street trees may cause injuries to human, vehicles and buildings. this research was investigated in the babol city, mazandaran province, in the northern state of iran.used the perfect inventory methods and measured the diameter at breathe height (dbh), height and hazardous criteria (dead woods, cracks or seams, decay, wound or cankers, root problems, weak branch unions and skew f...

(Horizontal and vertical tree community structure in a lowland Atlantic Rain Forest, Southeastern Brazil). The horizontal and vertical tree community structure in a lowland Atlantic Rain Forest was investigated through a phytosociological survey in two 0.99 ha plots in the Intervales State Park, São Paulo State. All trees ≥ 5 cm diameter at breast height were recorded. 3,078 individuals belongi...

We present the first coordinated study of a 1-h mesoscale gravity wave event detected simultaneously by a Na Doppler lidar at Boulder, CO (40.1°N, 105.2°W), and a Na Doppler lidar and an airglow temperature mapper (AMTM) at Logan, UT (41.7°N, 111.8°W) in the mesopause region on 27 Nov. 2013. The vertical and horizontal wavelengths are ~16.0±0.3 and 342.0±10.4 km, corresponding to vertical and h...

A new airfoil design method for H type vertical axis wind turbine is introduced in the present study. A novel indicator is defined to evaluate vertical axis wind turbine aerodynamic performance at variable tip speed ratios and selected as the airfoil design objective. A mathematic model describing the relationship between airfoil design variables and objective is presented for direct airfoil de...

As the wind power market grows rapidly, importance of technology for real-time monitoring and diagnosis turbines is increasing. However, most developed technologies research mainly focus on large horizontal-axis turbines, conducted small- medium-sized rare. In this study, a novel low-cost health system small H-type Darrieus vertical axis turbine proposed. Turbine operating conditions were class...
