It will cost $2,800 to acquire a small ice cream cart. Cart cash flows are expected to be $2,000 a year for three years. After the three years, the cart is expected to be worthless as that is the expected remaining life of the cooling system.
In this type of transfusion, athletes use the blood of someone else with the same blood type. EPO injections. EPO is a hormone produced by the kidney. It regulates the body's production of red blood cells. In medical practice, EPO injections are given to stimulate the production of red blood cells.
Doping is the process of adding impurities to intrinsic semiconductors to alter their properties. Normally Trivalent and Pentavalent elements are used to dope Silicon and Germanium.When a intrinsic semiconductor is doped with Trivalent impurity it becomes a P-Type semiconductors.The P stands for Positive, which means the semiconductor is rich in holes or Positive charged ions.ence N-type (Negative Type) extrinsic semiconductor (silicon in this case) is made by doping the semiconductor with pentavalent element. To create a P-type semiconductor, all we must do is to pop in a trivalent element into the lattice. A trivalent element has three electrons in its valence shell.
