A. Green roof help in reducing water logging in roofs, thereby reducing the dampening of the concrete, and increasing the longevity of the roof.
B. It is actually energy saving, by reducing the summer temperatures by evaporation and transpiration. It also maintains a warm room temperature in winter by reducing the heat loss.
C. It's also actually low in budget. Its initial cost is more than ordinary roof, but the maintenance cost is very low, if not nill.

The bionic pancreas is bio-engineered device used for the regulation of blood sugar levels in order to maintain body homeostasis. The bionic pancreas includes a sensor that monitors blood sugar levels and sends a signal to a separate device that will then release the appropriate hormone into the bloodstream to return blood sugar levels back to normal. This device is very functional because of its ability to dose insulin and glucagon based on continuous sugar blood measurements.
