Our assumption is that, due to grain boundaries acting mainly as barriers or sinks for dislocations, the smaller the grain size, the smaller the expansion of dislocation loops and thus the smaller the increase rate of mobile dislocation density. As a consequence of this assumption, both mobile ...
A voucher specimen (AN04) was deposited at the herbarium in the Department of Biology (College of Science, University of Hail, Hail, Kingdom of Saudi Arabia). For the experiment, 4 g of air-dried aerial parts were macerated in 100 mL of methanol-80% at room temperature for 72 h. The...
In general, the entire Paleozoic basement displays a very-low to low grade metamorphism, though it can reach the medium and high grade in the metamorphic domes that occur along the Axial Zone, mainly involving the Precambrian and Cambro–Ordovician terrains. The Paleozoic basement of the Axial ...
