Compared to the conventional methods, Artificial Neural Networks (ANN) are considered to be one of the reliable tools for modeling of complex phenomena such as demand. Aim of this study is to provide a model for gasoline demand in transportation section of Tehran metropolis through multilayered perceptron neural network and using the presented model in analyzing the sensitivity of the model to ...

The droplet burning characteristics of binary blends of iso-octane, n-heptane and toluene were studied in an ambience that minimizes external convection and promotes spherical droplet flames. The results are compare...
PURPOSE Existing literature shows negative relationships between gasoline price and motor vehicle crashes, particularly among teens. This paper extends that literature by evaluating the relationship between gasoline price and self-reported risky driving among teens. DESIGN Observational study using multivariate empirical analysis, using pooled data from the Youth Risk Behavior Survey, waves 2...
Westudy a dual-channel supply chain under decentralized setting in which manufacturer sells to retailer and to customers directly usingan online channel. A customer chooses the purchase-channel based on price and service quality. Also, to buy product from the retail store, the customer incurs a transportation cost influenced by the fluctuating gasoline cost. Both companies are under the revenue...
T history of automobiles is inextricable from the story of one of the most pervasive toxic chemical exposures in modern human history. Globally, billions of people were poisoned by lead (Pb) between 1921, when General Motors Corporation introduced tetraethyl lead as an antiknock agent in gasoline-powered cars, until 2015, when leaded gasoline was scheduled to be phased out in Algeria, the last ...
Four new or updated epidemiologic studies were presented at a meeting on the health effects of gasoline exposure held in Miami, Florida, November 5-8, 1991. A focus of these studies was whether there is a relationship between gasoline exposure and kidney cancer and leukemia. For gasoline distribution workers, who have a relatively high exposure, there was some evidence for a kidney cancer relat...
phytoremediation has gained increasing attention in recent years because of its ability to clean up and redevelop brownfield sites. petroleum hydrocarbon-contaminated sites are among most prevalent industrial sites in iran as one of the top oil producers in the world, which are in great need of remediation to prevent associated environmental and human health risks. a greenhouse study was conduc...
consumption of leaded gasoline in iran cause to emit lead compounds in ambient air of gasoline stations and is known to effect on workers health in these locations. the objectives of this study were assessment of ambient lead levels and blood lead levels of gasoline station workers in hamadan city, iran. for this purpose, 82 samples were obtained in ambient air of gasoline station locations. se...
Banana varieties have a significant effect on the reducing sugar content in peel. In recent years, potential efforts been directed towards utilization of cheap renewable agricultural resources, such as banana peel waste alternative substrate for ethanol production. Various conversion pathways are compared from technical, economic, and environmental points view. This study also deals mainly with...
Online appendix figure I shows the dynamics of the effect of a change in the price of regular gasoline on the share of gasoline that is regular grade. The plot shows that a permanent increase in the regular price would increase the share of regular gasoline for at least six months. Online appendix figure II shows the distribution across households of the correlation between buying regular gasol...
