Studies were carried out on the localization and mapping of gas stations in the urban area of São Carlos city, for an environmental diagnosis related to soil, surface water and underground water contamination resulting from likely leaking in fuel underground storage tanks. Considering that a provision of legal restriction makes it possible that most of public areas are not located in gas statio...

 The influence of five pure diets of isonitrogenous and isoenergic with different ratios of Clupeidae fish oil (F) and soybean oil (S) on growth, molting and survival of narrow-clawed crayfish, Astacus leptodactylus, was evaluated during an 8-weeks trial. As soybean oil replaced with fish oil in each treatment, gently. Test diets were inclusive F0/S100, F30/S70, F50/S50, F70/S30 and F100/S0 fis...

abstract khuzestan province accommodates the largest oil-fields with huge petroleum production in iran. oil spills through transportations, oil pumping station and storage tanks are the cause of frequent contamination in land areas, including crop fields, imposing great damages to soil ecology. thus, oil removal from contaminated soil by advance technologies such as bioremediation seems to be o...

In this paper, the dynamic analysis of fuel storage tanks has been studied and some equations are presented for the created fluid waves due to storage tank motions. Also, the equations for finite elements of fluid and structure interactions, and boundary conditions dominant on structure and fluid, were researched. In this paper, a numerical simulation is performed for the dynamic analysis of a ...
