more than 80% of iran’s area has arid and semi arid climate. therefore, iran is exposed to desertification process. practical activities in controlling desertification must be based on current desertification situation and its severity. based on this theory, evaluating desertification rate indices in khezrabad region was done based on imdpa model. in this research two factors with 10 indices we...
today one of the ecological crisis is the phenomenon of desertification that affecting the world. desertification is more related to social and anthropogenic issues than natural causes and it becomes more important over the time. monitoringis the systematic collection and analysis of information as a project progresses. in this study, using ahp method and gis techniques has been to assess deser...

despite the different criticisms on contrastive analysis it has been proved that the results of it(when processed) can be useful in a tefl environment, specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims.the consonants,vowels,stress and intonation of the two languages are described by the same model...
Today, degradation of soil and water resources are the most important factors of desertification in arid and semi-arid areas as a result of mismanagement and improper human behavior. Enforcement measures in relation to desertification control have to be based on knowledge of the current state of desertification risk and its severity. In the present study, to evaluate the risk and severity of de...
abstract foreign and iranian cultures are far distinct in the constraints imposed on writing and translating for children, since the iranian literary system is mainly concerned with cultural and religious instructions which lead to manipulation of translated texts. this study sought to identify the cultural and social constraints and norms which determined the strategies applied in the transl...

a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
desertification is a major problem in many countries. international efforts have been considered to combat and prevent this phenomenon. the most important cases of these measures are the united nations convention to combat desertification. in this study, imdpa model and gis were used to assess desertification phenomena in kashan plain. some indices of climate and water criteria were selected to...
abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...
