Introduction: Voxel based morphometry is a type of statistical parametric mapping that can be used to investigate the effect of diseases such as epilepsy, Alzheimer's disease and Parkinson's disease or other agent such as skills on brain structure (white matter, gray matter and cerebrospinal fluid). The aim of this study is evaluate the effectiveness of this method in detection of differen...

desertification is specific phenomenon of arid, semi-arid, dry sub humid regions. this phenomenon has a high rate in developing countries such as iran. the main objective of this research was calibration of imdpa model in abuzeidabad (kashan) region with emphasis on land criteria. imdpa model, introduced by iranian researchers to assess desertification intensity in iran. before application, the...

multi-part words in english language are hyphenated and hyphen is used to separate different parts. persian language consists of multi-part words as well. based on persian morphology, half-space character is needed to separate parts of multi-part words where in many cases people incorrectly use space character instead of half-space character. this common incorrectly use of space leads to some s...

Phase inversion in liquid-liquid dispersions corresponds to the transitional boundary between Oil-in-Aqueous dispersion and Aqueous-in-Oil dispersion. A theoretical model based on simple assumptions was proposed to predict phase inversion point, ambivalence region and the hysteresis effect of inversion. Experimental data from the literature were used to validate the model and results were c...

Desertification is more related to social and anthropogenic issues than natural causes and it becomes moreimportant over the time. Human effects on desertification could be classified as direct and indirect factors. This studyhas focused on the effect of management factor, as a dominant case, on desertification of Kashan region based onIMDPA (IMDPA: Iranian Model of Desertification for Potentia...

one of the characteristics in iranian model of desertification potential assessment (imdpa) is vegetation. sincevegetation is very important factor in the degradation of land, so some indices were determined for this item in order toevaluate desertification potential of arid, semi arid and arid sub humid areas of iran. the indices included vegetationcondition, exploit and revegetation. to calib...
