What are the biodegradation rates of hydroxyapatite, bioglass 45c5 and bioglass A/W? What are they measured in? Thank you!
I have a massive of x, y, z coordinates of 2D surface in 3D space, which builded in Ansys HFSS or AutoCAD. How can I get the analitical aproximation of this surface by formulas?
