21. Carriers such as electrons and holes can only have discrete energy values inside the quantum well. 22. Correct accounting for this saved energy can be accomplished with life-cycle analysis using real energy values . 23. He began measuring the free energy values related to several chemical processes, both organic and inorganic. 24. CIN is expressed as a negative energy value . 25. Fat has twice the energy value of muscle. 26. According to elementary quantum mechanics, electrons in an atom do not take on arbitrary energy values . 27. Only certain energy values , which are solutions to one or either of these two equations, are allowed. 28. These energy functions are based on deriving energy values from frequency of appearance on a structural database. 29. The ( unquantised ) band energy values are removed from the raw DCT coefficients ( normalisation ). 30. This applies to the total energy of systems, although different observers disagree as to the energy value .
