Background & Aims of the Study: The aim of this study is spatial distribution of arsenic (As) under the influence of chemical fertilizers using geostatistics in city of Eghlid, Iran. Materials & Methods: In this descriptive study, spatial distribution of arsenic was randomly investigated in 100 soil samples and its content was measured by ICP-OES. Spatial distribution of As and geostatistic...

ultrasound images suffer of multiplicative noise named speckle. different de-speckling algorithms run either in spatial domain or in transformed domain. in this paper, an adaptive filter in spatial domain according to assume the nakagami distribution as the statistic of log-compressed ultrasound images is used. for de-speckling in transformed domain, the non-sub sampled shearlet transform is us...

Lectin binding histochemistry was performed on the developing sympathetic ganglionic cells to investigate the distribution and density of defined carbohydrate terminals on the cell surface glycoproteins during autonomic system morphogenesis. Sprague-Dauley rat embryos from 9th gestational day to birth were fixed and paraffinized. Serial sections of these specimens were incubated with different ...

continuous soil quality evaluation in is necessary agricultural regions to sustainable soil management and profitable agricultural production. the objectives of this study were comprised of an evaluation of soil quality utilizing integrated quality index (iqi) along with its spatial distribution in qazvin province. iqi was calculated and its spatial changes analyzed using different interpolatio...

In recent years, the studies of location play a key role in success and stability of economic activities. Location studies are under consideration in both national and international levels. Meanwhile, identification of goals and methods of solving location problems have significant importance. The purpose of this paper is to examine spatial distribution of economic activities in 14 zones of Esf...

Functional quality of the student residence halls has a great deal of importance due to their collective nature and the fact that they are considered as housing units, identifying and defining the role of intermediary spaces on the spatial organization and and spatial consociation of student residence halls which is a compound system of masses and spatial borderlines can bring order to its syst...

some soil physical and chemical characteristics were analyzed in order to reveal the relationship between forest soils and regeneration patches. gorazbon district of kheyrud was selected as a case study for the research area. all regeneration patches were recorded using gps device. to assess the spatial structure and to quantify the metrics of regeneration patches, analyzing of landscape metric...
