generally heavy metals exist in all soils, but soil pollution is rising by time due to human activities. soils in the proximity of mines are more pruning to pollution of heavy metals due to mine exploring and excavation. this research was carried out to evaluate the soil pollution of sepahanshahr suburb with pb, zn and cd. during a field work campaign 100 soil samples were selected randomly fro...
This paper examines the inter-relationship of three major phenomena- population growth, uncontrolled urban expansion and urban development in Ado Ekiti, Nigeria. Uncontrolled urban expansion has a resultant effect on the urban development of a city whereas uncontrolled urban development is caused by uncontrolled population increase is caused by Migration. This work encapsulates how population g...
Rapid growth of urbanization and its complications in recent decades has absorbed urban planners' attention to stability and stable development issues. In this regard community which is the core stone of urban development stayed away from formal system of spatial planning, and established communities are in contrast with preserving stable development rules and principals, therefore this researc...
The rural centers integrations in the city which in some countries have been named as “urban villages” are the consequence of rapid urbanization and accelerated growth of our city. Since the rural centers integration in the city has been often without any plan, it has had various consequences on the environmental, physical, economical and social aspects. The present study has paid attention to ...
land-use spatial allocation is a multi-objective collaborative spatial optimization methodfor rational use of the land use. based on global search capabilities and the information feedbackmechanism of ant colony optimization (aco), a land-use spatial allocation model (aco-la) isproposed. firstlyfirst, a construction graph is built for modeling the land-use spatial allocationproblem. secondlysec...
one of the critical issues related to sustainable urban in twenty-first century, is the growth and development of the city in space and on this basis, the civil management was forced to think about urban development. tehran metropolis with its growing, developing immersive and without physical, environmental instability surrounding the statue has arrived. one of the ways for decentralization an...
This article attempts to analysis the development challenges in Iran’s rural spaces. This is based on production of space Trialectic theory and at the end this is linked with future studies. In order to understand rural spaces, we have to use Lefebvre Trialectic concept of shape which explains three “moments”, Special practice, Representation of space and Space of representati...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
pay attention to the public transportation, cycling and pedestrian oriented development (pod) and car-free streets can increase the quality of urban spaces and create more secure pedestrians with psychological comfort for human. old urban fabric with hidden physical, historical, and cultural values has been the best evidence of urban identity and meanwhile, the life and growth of this fabric ha...
by examining the level of inequality in the distribution of services and identifying the spatial pattern of injustice in the city, we can find out which of the services are in a more unfavorable situation than in this way, city management with conscious performance in spatial distribution of public services and social interests. , Reduce spatial inequalities and improve the quality of life and ...
