Ok I so don't understand what you are asking. Can you "spell" it out for me??

A PVC is a premature ventricle contraction.  It is caused when the atrioventricular node discharges its electric current before the sinoatrial node gets a chance to fire itself.  The atria sit, so to speak, above the ventricles and when the SA node fires, the atria contract, which fills the ventricles.  The electric current then travels to the AV node which contracts the ventricles and pumps the blood to the body.  But when the AV node fires before it receives its current from the SA node, the result is a premature ventricle contraction.

Before the introduction of plastics in the building industry, cast iron, pressed steel and zinc were in common use for gutters and rainwater pipes.  When plastics were developed, PVC became the preferred plastic due to its lightness, ease of installation and resistance to deterioration. In my experience the time taken to fit plastic materials is approximately half to one third that of traditional materials.  Plastics are also smooth on the surface reducing resistance and allowing  water to flow more freely.

What do you mean by the quistion i think it is not understood?

Hardly, it's slang. And if you need to really need to know, I won't go into details here. Look it up in the following link.

"cuz I dont have material"\n\nWhat does the above mean ?

It means that it is recyclable. The number indicates the type of plastic. The numbers are\n1 = Polyethylene terephthalate\n2 = High-density polyethylene\n3 = Polyvinyl chloride\n4 = Low density polyethylene\n5 = Polypropylene\n6 = Polystyrene\n7 = Any other plastics

You're best bet is to contact the resin manufacturers.  When you get the operator just tell them you have a technical question regarding (whatever you want) and they'll transfer you immediately....for some reason most people wig out when they hear the word "technical."  Try Geon, Solvay, Vinnolit, Vinycel, Kaneka, Mitsubishi, or Formosa to name a few.  You might also have luck with PVC compounders such as PolyOne or Marchem.  Otherwise, you could by some books devoted to the subject - The Encyclopedia of PVC Vols 1-4 is an excellent resource.  However, unless you have a few hundred bucks at your disposal I don't reccomend this.  Good luck!

What is this referring to? Can you post a clarification?

DC means that you have a constant voltage.  A battery is a great example of DC.  I used to like to think of electricity as water- voltage is how high up the water tank is (the higher up it is, the harder it pushes the water down), resistance is how thick the downpipe is, and current is the volume of water that flows down.  All three are connected, eg a narrower pipe gives less current \n\nAC is as if your source pushes, then pulls, then pushes, etc, the electricity.  This is what you get in your power socket.  It looks a bit like a kid jumping up and down on a trampoline... he pushes as he hits the trampoline, and pulls as he flies up.  To use our water example: imagine a pump that pushes the water, then sucks it back, then pushes...\n\nNo idea how this relates to Venn diagrams, sorry
