In this paper, we describe the simulation of the traffic flow on a road with a construction zone. The simulation model is based on the cellular automata and the stochastic velocity model. The simulation results on a road with a construction zone are compared with them on a road without a construction zone. Although the analytical study indicates that the traffic flow on a road with a constructi...
T total cost of moving goods by truck over a highway system involves two basic compon~nts: -the public costs associated with construction and maintenance of the road network, and the privately financed costs of acquiring, operating, and maintaining a fleet of trucks. These publicly and privately financed costs are directly linked in many ways. For instance, the more trucks there are, the more w...
Background and Objective: Dolochar is the residual ash from the production of sponge iron in the process of direct reduction of iron ore by the coal-based method. In Iran, this waste is transported to the nearest landfill. However, these methods are a major environmental concern due to the fineness of the waste and the presence of heavy metals in its composition. The aim of the present study is...
Workers in the road construction industry include asphalt plant, ground construction, and road paving workers. These individuals can be exposed to a wide range of potentially hazardous substances. A summary of levels of exposure to different substances measured during road construction is presented. In modern road paving, workers typically are exposed to 0.1 to 2 mg/m3 of bitumen fume, which in...
iran is an important endemic focus area of cystic hydatid disease where several intermediate host species are commonly infected with echinococcus granulosus . annually, most livers are shipped out, stored away, or destroyed due to contamination among livestock. for instance, in aleshtar (lorestan province), liver and lung losses due to hydatid cysts during 2002-2003 were approximately 864,360,0...
