WebDASI score is calculated by adding the points of all performed activities together. The higher the score (ranges from 0 to 58.2) the higher the functional status. VO 2 peak (mL/kg/min) = 0.43 x DASI + 9.6. METs (metabolic equivalents) = VO 2 peak / 3.5. Best METS performed can also be used to predict functional capacity. http://www.corrosion-doctors.org/Corrosion-by-Water/Scaling-indices.htm WebApr 12, 2024 · Heidelberg Materials said on Wednesday it was teaming up with Linde to build and operate a carbon dioxide capture and liquefaction plant. readiness test upwork
