The doubly labeled water technique

WebTEE that takes into account physical activity can be measured using doubly labeled water technique (DLW). The isotope dilution technique uses stable isotopes ( 2 H 2 O, H 218 O, and NaH 13 CO 3) to measure energy expenditure. The DLW method is based on the differences in turnover rates of 2 H 2 O and H 218 O in body water. WebWhat technology, techniques, or processes were used to manufacture the bottle? 4.
