abstract: numerical weather forecasting models are used for forecasting and dynamic conditions analysis of atmosphere phenomena in recent years. this research investigates dynamic and thermodynamic conditions in heavier precipitation events in different synoptic patterns in the southern coasts of caspian sea using wrf model. database precipitation events were formed. super heavy and heavy preci...

Heavy haul freight railroads carrying bulk materials such as coal or iron ore are characterized by several unique challenges relating to investment in construction and maintenance as well as achievement of optimal operating efficiency. This paper examines heavy haul railroads around the world in a comparative context that highlights differences relative to operating parameters, degree of integr...

A good understanding of the influential factors to software development effort and further precise effort estimate are undoubtedly crucial to any cost-effective and controllable software development projects. In most effort estimation researches, a large dataset is always a necessary basis of estimation modeling, model calibration and method validation. Among them, different attributes and char...

in the world history, from ancient times up to now, the plague has been followed by heavy casualties on human societies and social order. one of the deadliest plagues is the great plague of the middle ages, or so-called black death. this plague, in the eighth and ninth ah (fourteenth and fifteenth century ad) swept over some large areas of asia, especially the middle east, as well as europe, an...

background: sediments in marine environment have a large capacity in binding with heavy metals; therefore, they are potential pollutants of water resources. the anzali wetland, located in the southern region of the caspian sea, iran, has been consistently threatened by heavy metal pollutants because of urban, agricultural and industrial wastewater inflow. the purpose of this study is to investi...

Background & Aims of the Study: Rhodococci according to possess large genome, their active metabolism and survival under extreme conditions, are highly regarded for biodegradation and bioremediation of different pollutants especially heavy metals in the environment. Biofilms are more resistant to heavy metals than free-swimming organisms. The aim of this study was biofilm forma...
