A numerical study on mixing of hydrogen injected transversely into a supersonic air stream has been performed by solving Two-Dimensional full Navier-Stokes equations. An explicit Harten-Yee Non-MUSCL Modified-flux-type TVD scheme has been used to solve the system of equations, and a zero-equation algebraic turbulence model to calculate the eddy viscosity coefficient. The main objectives of this...
One of the simple methods for erosion control, flood mitigation and flood damage reduction in the streams is building the checkdams. The present study was carried out to evaluate the performance of checkdams, location across the streams in the retention of the fine sediments in Droudzan watershed in Southern Iran. For this purpose, a number of streams with many stabilized check dams which were ...

Abstract. The temporal evolution of the characteristics of Denmark Strait Overflow Water (DSOW) is reconstructed using hydrographic data and compared with possible atmospheric forcing mechanisms. It is concluded that the main factor influencing the DSOW characteristics at a time scale of one to several years is the difference in mean sea level pressure across Denmark Strait or, in other words, ...

Varied flows such as flooding resulting from dam break can happen due to earthquakes, seepage, bombing, overtopping, mistake in design and project performance as well as causing financial damages and human losses. Unsteady flow during flooding events has a high impact on flow field pattern, sediment motion, ecology and also, distribution of contamination in the river. In this study, the impact ...
background: congenital heart disease (chd) is the most common congenital anomaly in newborns. this study was performed to determine the live birth incidence of chd by ethnicity and sex in gorgan, northern iran. methods: in this longitudinal, hospital-based study, 18162 live births in dezyani hospital in gorgan, north of iran, were screened for chd, from 2007 through 2009. clinical examination, ...
in a two-year study on natural enemies of tomato fruit worm, helicoverpa armigera (hubner) (lep.: noctuidae) in golestan province, two parasitoid wasps belonging to the family ichneumonidae were identified, which are newly recorded from iran: 1. hyposoter didymator (thunberg), which was collected in 8 july 2003, in seyed-miran, 9 km west of gorgan, and 2. ctenichneumon panzeri (wesmael), which ...
