In model building studies, it is important to check the energy conditions for corresponding energy-momentum tensor determined by gravitational field equations in order single out physically reasonable models. this process, one often encounters a situation where has off-diagonal "space-time" component frame with an orthonormal basis given spacetime. We derive useful criteria of tensors their Haw...

delphi as a consensus development technique enables anonymous, systematic refinement of expert opinion with the aim of arriving at a combined or consensual position. in this study, we determined the criteria and their weights for iranian medical schools' ranking through a delphi process. an expert committee devised 13 proposed criteria with 32 indicators with their weights, which were arranged ...

desertification in arid, semi-arid and dry sub-humid regions is a global environmental problem. considering theincreasing importance of desertification and its complexity, the necessity of giving attention to desertification criteria andindices is essential. models and methods such as medalus, unep-fao, and others have been proposed on local andnational scales. in this research, imdpa was selec...

desertification refers to land degradation phenomenon in arid, semi-arid and dry sub-humid areas, resulting from various factors including climate variation and human activities. for evaluation and mapping of desertification many research have been conducted leading to regional and local models. in this research, among different existing methods imdpa was selected and desertification intensity ...

knowledge of behavior climatic indexes can be help to planning future programs bahabad study area in the eastern part of the province of yazd with a hot and dry climate, high potential evapotranspiration and low rainfall has a high potential for desertification. the aim of this research is evaluation of classification intensity by imdpa model with emphasis to climate criteria. the indices inclu...
