Rock mechanics experiments show that the magnitude of intermediate principal stress significantly affects rock failure. Since triaxial states (no is zero) are ubiquitous in crust, and polyaxial axial (all three stresses different) general, should have an important effect on hydrothermal mineralisation. For example, extensional veins or dykes vein-hosted gold porphyry deposits may multiple orien...

To meet the increasing energy demand, renewable is considered best option. Its patronage being encouraged by both research and industrial community. The main driving force for most systems solar energy. It abundant pollutant free compared to fossil products.

A retrospective, single-center review was performed from 2014 to 2019. total of 64 iliac branch devices (IBDs) were placed in patients (n = 59; [92%] with the Gore excluder graft [W. L. and Associates, Flagstaff, Ariz]; n 5 [8%] Cook Zenith branched device [Cook Medical, Bloomington, Ind]). Technical success achieved 60 (94%). Previous endovascular aortic aneurysm repair (EVAR) 14 significantly...
