11. It's a mix of mechanical parts, computer software and solid state electronics. 12. They are easily the most important types of solid state memory today. 13. The product of such solid state processes are called direct reduced iron. 14. Microphotonics and nanophotonics usually includes photonic crystals and solid state devices. 15. The last run was apparently solid state instead of tube driven. 16. The imine tautomer is dominant, at least in the solid state . 17. Those findings, the jury said, led to important applications in solid state physics. 18. Valve amplifier circuits are significantly different from broadband solid state circuits. 19. This results in shorter sintering times compared to solid state sintering. 20. Audiophiles mostly agree that tube sets sound different from transistorized solid state sets.
