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 chemistry, to dissolve is to cause a solute to pass into solution. Typically, this involves a solid going into liquid phase, but dissolution can involve different phases. Stirring sugar into water is an example of dissolving. The sugar is the solute, while the water is the solvent.
