11. A better quality version of a heterodyne, or direct conversion , bat detector is the super-heterodyne detector. 12. He was also developing magnetohydrodynamic generators for the direct conversion of thermal energy into electric energy. 13. Suppression of CAF-1 also enhance the direct conversion of B cells into macrophages and fibroblasts into neurons. 14. This form can allow greater compression and direct conversion to / from JPEG files and video hardware. 15. As with S-parameters, T-parameters are complex values and there is a direct conversion between the two types. 16. Post helped develop the theoretical underpinnings of direct conversion , which was later demonstrated by Barr and Moir. 17. There are similarities in concept, but also major differences, and no direct conversions exist between these two types. 18. First, mirrors were easier to construct and maintain and second direct conversion energy capture, was easier to implement. 19. DC to DC direct conversion is more efficient, therefore, potentially allowing the more efficient capture of solar energy. 20. Direct conversion of particle energy to thrust is theoretically simpler, merely requiring magnetically directing a neutral plasma beam.
