suitability analysis is a prerequisite for sustainable agricultural production and it involves evaluation of the environmental parameters. the development and creation of appropriate points for this land use without considering environmental capability will result in the appearance of several ecological, economic, and social problems. the multi-criteria decision making (mcdm) models were used f...
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
sange siyah dam is located two kilometers down the kabod khani village. the environ of ghorrve city in kurdestan province. this is an clay core dam. in this dam instrumentation is performed in three section and consist of electrical piezometers, total pressure cells, settlement cells and so on. the main objective of instrumentation is to control the behavior of dam body and foundation, end else...
Existence of heavy minerals in waters in some regions causes serious environmental pollution and affects the soil and water resources quality. Soil and waters sensitive to pollutants were investigated in this research, based on the degree of sensitivity of their parameters. The samples obtained from industrial and agricultural areas for identifying water tables at higher risk and display region...
During the past 50 years, the media channels, the media consumption patterns and the entire influence of media in society have changed dramatically. Looking into the future, the pace of change is not likely to decrease. In order to prepare for the future, it is important to increase our understanding of the present, in particular with regards to the environmental aspects of media consumption. I...
In thee meteorological observation points were installed identical weather stations and a network infrastructure were created to receive and record the environmental parameters at every minute. A series of six out of forty-four parameters relating air, and solar radiation were taken into the analysis. The inference between observed data in three different locations was analyzed in order to find...
The use of polarimetric techniques is nowadays widespread among solar and stellar astronomers. However, notwithstanding the recommandations that have often been made about the publication of polarimetric results in the astronomical literature, we are still far from having a standard protocol on which to conform. In this paper we review the basic definitions and the physical significance of the ...
