The left ventricular ejection fraction (LVEF) test rate is increasingly used as a quality of care indicator for pa-. tients with heart failure. Our study produced benchmark LVEF test rates in a Medicare fee-for-service.
Toluene is a very good solvent because, unlike water, it can dissolve many organic compounds. In many commercial products, toluene is used as a solvent that is present in paint thinners, nail polish remover, glues, and correction fluid. Toluene has many uses in different industries.
In the laboratory, toluene is used as a solvent for carbon nanomaterials, including nanotubes and fullerenes, and it can also be used as a fullerene indicator. The colour of the toluene solution of C 60 is bright purple.
