the urban heat island effect refers to the temperature rise of the cities in comparison to the suburbs. this phenomenon which is a consequence of urbanization and has become a major issue in the urban climatology may have serious consequences in the developing countries which are facing a rapid and unplanned urban growth. tehran, the capital and the most populated city of iran, this phenomenon ...

Introduction: RFamide-related peptide (RFRP) is believed to act as an inhibitor of gonadotropin releasing hormone (GnRH) secretion. The aim of the present study was to compare the expression pattern of RFRP neurons in the dorsomedial nucleus of hypothalamus (DMH) at different phases of the rat estrous cycle. Methods: The phases of the estrous cycle were determined in 16 adult female Sprague-...

In north of Anarak area, in the upper Proterozoic ophiolite, exist Massive and Vein type Rodingites. Vein type rodingites have formed in two phases. Massive or Static rodingites have formed during oceanic crust spreading and ophiolite formation, and Vein type or Dynamic rodingites have formed during Anarak ophiolite emplacement and tectonic activities. Abundance order of minerals in massive rod...

We model the T-Phase transition from ocean to land and evolution of the seismic signal through this process. We model the transition with a composite technique using normal mode based numerical propagation codes to calculate the hydroacoustic pressure field in the ocean, and use this pressure field as input for the elastic finite difference code TRES to calculate the seismic propagation to land...
