To assess genetic diversity and maternal origin of Turkish and Iranian native chicken breeds, we analyzed the mtDNA D-loop sequences of 222 chickens from 2 Turkish (Denizli and Gerze) and 7 Iranian (White Marandi, Black Marandi, Naked Neck, Common Breed, Lari, West Azarbaijan, and New Hampshire) native chicken breeds, together with the available reference sequences of G. gallus gallus in GenBan...
the interactions and linkages between urban centers and peripheral settlements are increasingly recognized as key factors in the process of social, economic and environmental changes in peripheral settlements. despite this, most practices are implicitly based on a dichotomous view of population and activities in urban and peripheral area. this paper presents that how interactions between urba...
Sanitation improvement is crucial in saving lives that are lost due to water contamination. Progress towards achieving full sanitation coverage is still slow in low-income informal settlements in most developing countries. Furthermore, resources are being wasted on installing facilities that are later misused or never used because they do not meet the local demand. Understanding demand for impr...
The paper presents a theoretical model that seeks to answer the question of why former squatter settlements tend to upgrade/redevelop at a slower pace than otherwise similar settlements originating in the formal sector. We argue that squatter settlers’ initial strategy to access urban land creates a ‘legacy effect’ that curtails settlement upgrading possibilities even after the settlements are ...
A mechanical spring-block model is used for realizing an objective space partition of settlements from a geographic territory in region-like structures. The method is based on the relaxation-dynamics of the spring-block system and reveals in a hierarchical manner region-like entities at different spatial scales. It takes into account in an elegant manner both the spatiality of the elements and ...
To visualize the structure of Iranian chemistry scientific publications in SciSearch, 43 Iranian and International chemists were identified. They were the highly cited scientists in 7682 Iranian chemistry publications (defined as an article with at least one Iranian author address) indexed in Science Citation Index during the period from 1990 to 2006. Co-citation data for these authors from the...

Intellectual property rights are widely recognized as critical assets in many industries, especially “high-tech” industries. Companies like IBM, Intel, and Hewlett-Packard regard their patents and copyrights, along with their other intangible assets such as know-how, as central elements giving them competitive advantage. Likewise, many software companies, from Microsoft to software startups see...
BACKGROUND: Because of the vulnerability of human settlements to natural disasters and damage caused by them, the study of the resilience of settlements has become critical in planning urban areas. The purpose of this paper is to evaluate resiliency of Baghershahr, a town with a population of 65000, locates in 4 km from Tehran city, against earthquake. METHODS: The research data were collected...
