Introduction: Due to water scarcity and increased water consumption during the past years, the importance of water in terms of transmission of diseases, as well as Iran's climate, groundwater aquifers are known as the most important resources of drinking water supply. Using the Water Quality Index (WQI) is considered as strong managerial tool for decision making in water resource management. Th...

One of the main factors of water erosion is the natural characteristics of the soil called "erodibility" or"detachability". The present study aims to analyze the variations of soil erodibility factor in different plains and thefactors related to it. Erodibility is one the key factors in some models of erosion and sediment such as Universal SoilLoss Equation (USLE), Revised USLE (RUSLE), and Mod...

Algebraic varieties that are locally isomorphic to open subsets of affine space will be called plain. Plain varieties are smooth and rational. The converse is true for curves and surfaces, and is unknown in general. It is shown that plain varieties are stable under blowup in smooth centers.

the kalut-e-ashrafa area is located in the north-east of ardakan area in central iran, yazd province. this area promises copper mineralization. the most of the minerals in this study area are silica-rich veins and veinlets. therefore, in order to identify geological formations with silica zones and to determine potential mineralization areas, aster images and remote sensing methods were used. a...

I define the plain Anabaptists by answering two essential questions: “Who are the plain Anabaptists” and “What are the plain Anabaptists?” In asking “Who are the plain Anabaptists?” I investigate several dimensions of identity. First, I trace the history of seven religious traditions within Anabaptism: the Swiss Brethren/Mennonites, the Low German/Russian Mennonites, the Hutterites, the Amish, ...

In order to recognize the wind erosion situation of a region, the survey of its windiness is not sufficient and the physical characteristics of earth are of importance too. In fact, the outbreak of dust storms in a region is due to the sensitivity of earth and domination of wind in that region. In this investigation we have tried to find a way for determining the regions in which a dust storm i...
