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.
Throughout most of the U.S., the temperature of the ground below the frost line (about 3 to 5 feet below the surface) remains at a nearly constant temperature, generally in the 45 Â° -50 Â° F range in northern latitudes, and in the 50 Â° -70 Â° F range in the south.hroughout most of the U.S., the temperature of the ground below the frost line (about 3 to 5 feet below the surface) remains at a nearly constant temperature, generally in the 45 Â° -50 Â° F range in northern latitudes, and in the 50 Â° -70 Â° F range in the south.
