For species in which group membership frequently changes, it has been a challenge to characterize variation in individual interactions and social structure. Quantifying this variation is necessary to test hypotheses about ecological determinants of social patterns and to make predictions about how group dynamics aVect the development of cooperative relationships and transmission processes. Netw...

BACKGROUND Hypertension is one of the most crucial health problems and the most common chronic disease in developed and underdeveloped countries. It is called the silent killer which is usually diagnosed incidentally.

The structural analysis of large intracontinental wrench faults is fundamental for deciphering the long-term evolution continental crust in complex areas terms their geodynamic and large-scale crustal block displacements. In this contribution, we demonstrate a pre-Miocene dextral activity present-day left-lateral Great Kavir - Doruneh Fault System (GKDFS, Central Iran), one major active strike-...

due to difficulties in the application of traditional methods for identifying sediment sources, fingerprinting techniques, based on physical, chemical and organic properties of sediment and source materials, are increasingly being used as a valuable and effective alternative approach to obtain such information. the first step in this method is using an appropriate combination of diagnostic prop...

Air pollution is a consequence of human activities, especially in the period after industrial revolution, which has many (direct and indirect) effects on the human and the environment around him. Among different kinds of pollutions, those related to industries and mines are much more dangerous. Therefore, it is necessary to identify these pollutions and specify them so as to reduce the harmful ...

stylolite networks and their insoluble residues (ir) are among the major concerns and the fundamental controls on the mining and processing of sedimentary decorative stones, largely made from dolomitized limestones. they are mainly used, as natural rock blocks and polished slabs, to construct and decorate floors and walls of buildings and monuments. representative quarries in khur areas, east o...
