the ple2scx vector was developed for the stable expression of exogenous genes in the protozoan parasite leishmania. the ple2scx construct contains three independent selection markers: herpes simplex virus thymidine kinase (hsv-tk), cytosine deaminase (cd) and streptothericin acetyltransferase gene (sat) in multiple cloning site, flanking by 5’ and 3’ untranslated regions of the previously clone...

Choosing a location for a power plant site is a complex task that involves evaluation of multiple factors, which should satisfy a number of economic and environmental requirements. The main aim of this study is to determine the best possible candidates for thermal power plant sites using Multi-criteria Evaluation and Geographic Information System (GIS) in Kahnuj County in the southeast of Iran....

This paper presents the criteria and applied methods in the screening of potential sites for the wastewater treatment plant of the Falavarjan district, northwest of Esfahan province. For this the nine parameters that were selected as main criteria, 7 parameters were considered to define the buffer zones in the natural and artificial terrains. At the first stage of the study, unsuitable zones we...

Rough Sets theory is a mathematical approach for analysis of a vague description of objects presented by a well-known mathematician, Pawlak (1982, 1991). This paper explores the use of Rough Sets theory in site location investigation of buried concrete water reservoirs. Making an appropriate decision in site location can always avoid unnecessary expensive costs which is very important in constr...

Background & objectives: The disposal of hazardous waste in the environment, which is usually done by burying it in a special landfill, requires a set of environmental standards and special economic, social and managerial considerations. Improper landfills can have negative health, economic, and environmental effects. In this regard, the present study seeks to find a suitable landfill for speci...
