in this paper, the nucleation and growth of diamond/diamond-like coatings on austenitic (aisi 316) and ferritic (aisi 430) stainless steel substrates have been investigated using torch technique. the effects of substrate surface preparation has also been studied. the quality of coatings produced has been examined using optical and scanning electron microscopy, x-ray diffraction, raman spectrosc...

Non-metallic inclusions and twin boundaries are preferred fatigue crack nucleation locations in polycrystalline Ni-based superalloys. A Heaviside HR-DIC, EBSD multi-scale modelling strategy (CPFE-DDP) was used to assess experimental observations of near agglomerated RR1000 at elevated temperature. Inclusion fracture decohesion were observed within the first cycle loading. Fatigue non-metallic i...

The force-generating capacity of cardiomyocytes rapidly changes during gestation and early postnatal life coinciding with a transition in cardiomyocyte nucleation in both mice and rats. Changes in nucleation, in turn, appear to coincide with important changes in the excitation-contraction coupling architecture. However, it is not clear whether similar changes are observed in other mammals in wh...

strength and duration, that have, so far, characterized economic activity. January 31, 2001: Preliminary real GDP growth for the fourth quarter is barely above 1 percent, more than 4 percentage points below what is was only two quarters before and about 7 percentage points below its level in the third quarter of 1999. Much of the press, and some forecasters, predict that the first quarter of 20...

globalization and democracy have become the most debated issues throughout the world, which, no doubt also influence iran. this paper highlights these phenomena with respect to iran but takes up the issue through various description and features presented by the con-temporary socio- political thinkers and economists. considering globalization, although the subject matter is very recent but iran...

The cell nucleus contains a large number of membrane-less bodies that play important roles in the spatiotemporal regulation of gene expression. Recent work suggests that low complexity/disordered protein motifs and repetitive binding domains drive assembly of droplets of nuclear RNA/protein by promoting nucleoplasmic phase separation. Nucleation and maturation of these structures is regulated b...
