The six steps of the sand casting process are; placing the mold in patern in sand, setting up the gating system, removing the mold pattern, pour molten metal into mold cavity, wait for the metal to cool, the final step is to break open the mold to remove the casting.


It is directed by a machine called a thermocycler, which is programmed to alter the temperature of the reaction every few minutes to allow DNA denaturing and synthesis. How does PCR work? To amplify a segment of DNA using PCR, the sample is first heated so the DNA denatures, or separates into two pieces of single-stranded DNA.

covered by photoresist. This process is called doping, because impurities are introduced into the silicon. This alters the conductive properties of the silicon (making it conductive or insulating, depending on the type of ion used) in selected locations. Here we show the creation of wells, which are regions within which transistors will be formed.
