OPTIMIZATION DESIGN OF NEW BIONIC PROPELLER

Optimization Design of New Bionic Propeller

A novel method for optimal design of hydrodynamic performance of bionic propeller with a deformable leading edge is proposed.Based on the bionics principle and method of parameterized modeling, the fore-fin concave-convex structure of humpback whales is applied to the propeller leading edge, the leading edge in the propeller to meet flow region acc

Activation of FGF signaling mediates proliferative and osteogenic differences between neural crest derived frontal and mesoderm parietal derived bone.

As a culmination of efforts over the last years, our knowledge of the embryonic origins of the mammalian frontal and parietal cranial bones is unambiguous.Progenitor cells that subsequently give rise to frontal bone are of neural crest origin, while parietal bone progenitors arise from Matching Shirts paraxial mesoderm.Given the unique qualities of
