abstract: since sugar consumption is directly related to diabetes and other illnesses such as obesity, the issue that will most heavily dominate the health food market is blood sugar management and low glycemic foods. using calcium chloride and gums such as sodium alginate and low ester pectin as thikener and a high-potency sweetener aspartame we were able to reduce sugar content of sour cherry...
writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
The Standardized Precipitation Index (SPI) has become a popular measure of drought across the globe. In this study, Standardized Precipitation Index (SPI) was used in annual period of time to survey on drought. Also, in order to zonation frequency of drought, geographic information system (GIS) software and Kriging method used for extracting dry areas. The zoning maps show most severe drought i...

Landslide is one of the destructive phenomena of natural resources and threatens the sustainability of forest roads. The purpose of this study is to determine the zoning of land risk for the stability of forest roads using the process of analyzing the hierarchy in the GIS. The final zoning map of landslide hazard based on the combination of different maps and main criteria of topography, vegeta...
Introduction and Purpose: Mashhad, one of the most populous cities in Iran, is facing air pollution due to motor vehicle emissions and industries. Therefore, this study aimed to evaluate the variations in Air Quality Index (AQI) during the spring of 2012-2014 and its spatial zoning with Arc GIS. Methods: In this descriptive study, the AQI values were calculated by the associ...
Gully erosion is the most advanced water erosion in watersheds that produce large volumes of sediment can cause serious damage. In order to manage and cope with this type of erosion, to identify areas of high risk of gully erosion in the watershed is very important. For this purpose gully erosion hazard zonation maps by combining information layers of different factors affecting the formation o...
Risk assessment provides the possibility of planning and management to prevent and reduce the risk of desertification. The present study is aimed to assess the hazard and risk of desertification and to develop management programs in the semi-arid western regions of Golestan Province in Iran. Desertification rate was obtained using the Iranian model of desertification potential assessment. Since...
the aim of this research is to analyze the performance of 8 drought’s index in isfahan, kerman and yazd province and choose the best index. for this purpose, used monthly and yearly rainfall data in the period of 30 years (1985-2014) and also used 8 drought indexes in 20 meteorological stations of central iran which the accuracy of each index in determining drought is examined. also zoning in a...
in order to agroecological zoning of current agricultural lands in golestan province for canola cultivation, geographic information system (gis) and analytical hierarchy process (ahp) were used to match the environmental requirements of crop and the land characteristics. the first, agroecological requirements of canola was identify from scientific resources then classified and needed thematic m...
