The price of the device has been steadily increasedâby 32 percent in the past year aloneâbut not because the cost of the raw materials was increasing (a typical dose of epinephrine still costs about a dollar). The profit margin of the EpiPen was 9 percent in 2008. Today itâs 55 percent.
Frost is a form of ice and can only survive at temperatures of 32 degrees Fahrenheit and below. But that doesnât mean the measured air temperature must be 32 or below for frost to form on a surface.
For other uses, see Frost (disambiguation). Frost is the coating or deposit of ice that may form in humid air in cold conditions, usually overnight. In temperate climates it most commonly appears as fragile white crystals or frozen dew drops near the ground, but in cold climates it occurs in a greater variety of forms.
