Pigeonpea (Cajanus cajan (L.) Millsp.) is a major food legume cultivated in semi-arid tropical regions including the Indian subcontinent, Africa, and Southeast Asia. It is an important source of protein, minerals, and vitamins for nearly 20% of the world population. Due to high carbon sequestration and drought tolerance, pigeonpea is an important crop for the development of climate resilient ag...
Dislocations are a common type of defects that signifi cantly infl uence many mechanical phenomena such as plastic deformation, crystal growth, morphology, or diffusion of materials. Although dislocations have been well-studied for simple crystalline structures such as pure metals, semiconductors, ionic materials, and binary oxides, there is very limited knowledge on such defects in complex-lay...
The city of Tehran undergoes an increasing growth in population as well as industrial activities, both of which increase the concentration of air pollutants. The current research tries to turn a limited and focused system of air contamination measurement and control to an unlimited and extensive one that examines the concentration of each of the contaminants in any area of Tehran. Accordingly, ...
The Great Basin of the Western United States has thin continental crust and geologic structures that have controlled the emplacement of significant precious and base metal mineralization. Many of the mineral deposits in the Great Basin were emplaced by hydrothermal processes that altered the mineralogy of their host rock assemblages and facilitated concentration of metals. In the 1960’s and 197...
Navigation systems have become an interesting research and industrial topic due to their wide deployment. The method of updating the map database (DB) with previously unknown map information has become an important factor in navigation system design. At present, multiple map DB providers maintain their own datasets and work to reduce unknown map information in only their proprietary maps. Map u...
