Generation curve income

C-D The cash-flow curve turns up at C, as the process comes on stream and income is generated from sales. The net cash flow is now positive but the cumulative amount remains negative until the investment is paid off, at point D. 

A mathematical model of the leg was developed to predict the cooling curve under various conditions. Factors which were important in determining the rate and final level of cooling include the diameter of the leg, blood perfusion rate, and the presence of subcutaneous fat. Metabolic heat generation and the presence of bone are relatively unimportant. Heat carried into the leg by incoming blood is sufficient to maintain a temperature of 8°-10°C at the center of the leg. 

Figure 2.78. Typical example of a DPC ran on a UV-curable resin covered with PVDF film (see discussion below) and irradiated for 2 min with a UV intensity of 53 mW/cm. Run 1 = uncured sample, and run 2 = same sample immediately following the first irradiation. Because the sample weight is unchanged and its UV absorption characteristics are similar before and after cure, run 2 may be used as the baseline and subtracted from run 1 to generate the true heat flow-time curve. A Perkin-Ehner DPC accessory with its water filter was used to minimize the IR component of the incoming radiation.
