21. It could conceivably be non-strange quark matter, if the effective mass of the strange quark were too high. 22. It is possible to average the different axes'effective masses together in some way, to regain the free electron picture. 23. "It's the most effective mass media and I think it will be for a long time, " said BBS'Singye. 24. But for all the talk, there is effective mass transit in metro Dallas, and there isn't in metro Phoenix. 25. This gives rise to an effective mass for the quarks, often identified with the valence quark mass in QCD. 26. This is because there are multiple valleys ( conduction-band minima ), each with effective masses rearranged along different axes. 27. From material to material, it is dependent on the electronic properties, especially on the effective mass of the electrons. 28. Doctors are concerned that these developments could undermine the Pap smear's strength as an inexpensive and effective mass -screening technique. 29. The wavefunction of the bound state is said to be " effective masses of the excited electron and hole. 30. If we regard the electrons as nearly free electrons, the Luttinger parameters describe effective mass of electron in each bands.
