Q: I know that computers contain toxic materials like mercury and lead, which is bad for you if you're exposed to it. A PS3 is basically a computer and I need to open it up.
The best type is the type that goes off when it's needed and saves your life:) I heard something recently about a new type that puts out a smell instead of making noise. They said in studies that it was more effective in waking people. I can't remember the name or if they are available for purchase yet.
Q: Land lord now. We have nasty old singe pane windows. Can we request to replace them with double pane windows and would it resolve the mold issue?
If they aren't welded, they don't count. If any are threaded and will be seal-welded later, they do count. If they have weld-neck flanges they do count. If there is no weld, why would they be counted?

Most of my lifestyles has been in Musical Theater. My youngest daughter on the second, is in Chorus Line. We party each 12 months, regardless of wherein we're, and appear on the Tony's in combination. There is not anything adore it. Funny Girl, Mame, Hello Dolly, Joseph and the Technicol Dreamcoat, Les Miserable - one would move on and on. When we went to peer Mama Mia, the film, it was once a extraordinary revel in. For the primary time in a film Theatre the complete viewers took facet. They stood up and sang, danced and we had been all a facet of the film. Music, personally, is without doubt one of the benefits which have been bestowed on Human Beings. My lifestyles might no longer be what it's, or has been, if it was once no longer for track and Musical Theatre, on movie or on level.

Q: May I ask what material EN39 is? Used to make a threaded pipe joint
Groove connection: This is the most advanced connection mode at present. There are two two connecting pipes, valves, or pipes and valves that are connected by clamps. In the outer pipe or valve connecting end have an annular groove manufactured according to the standard, when connected with a supporting clamp. Site construction, installation and disassembly are very convenient and quick. Not only the seal is reliable, but also saves time and material. It has incomparable advantages in large caliber connection.
Q: My grandmother has a vcr that she had me take a look at and all it will do is take the tape in and then eject it right back out. What could be causing this and it is not the tape because we tried several tapes and they all did the same thing. I am just trying to find out if it is worth repairing because it was made in september of 1993 so its like 15 years old but she insists on getting someone to work on and and i just think she should just trash it and buy a vcr and dvd combo. But what ever answers i get i will tell her.
Try using copper pipe instead of PVC it will hold up better in the long run and if the PVC is running a span of over 4 ft then it gets very shaky. My best advice would be go gt your pipe and fittings, go for it.
Q: SuRvEy:: - ::> How many Aardvarks does it take to make a really good speed bump?
From your spelling, I would guess you need school more than MySpace. Circumventing the blocks are probably in contravention of your school's/company's/usage policies and would not be a good idea, resulting in banning, suspension or expulsion. The fact that you have to ask how to do it leads me to believe that you do not have the technical skill to avoid being detected. If you want to access stuff like YouTube or MySpace, be aware that the more bandwidth you are using, the more you are taking away from other legitimate users of that system. The sites have probably been blocked for a very good reason. If you're accessing from a public space, i.e. school, library, college, or other public access point, you should ask the administrators why they have blocked those sites. Put your case as to why you should have access, but be prepared for a firm 'no'.
Q: In January Unemployment was at 8.6%. Any one want this Roller Coaster ride from the Rubber Band man for the next four years. Not ME, I happen to like Living with Food to Eat.

There are several different types of compression style fittings available to repair pipes in this situation. I suggest cutting off a very short piece of the pipe and bring it to a local plumbing wholesale store or plumbing shop tmrw and they can show you a fitting that will work. Some brands that could work are - sharkbite - john guest fittings - Jaco fittings - philmac couplings the advantage of a compression fitting is that there is no glue or cement required to seal the joint. The seal is made by a nut and ferrul, rubber gasket or plastic washer. Most of these compression fittings are available from 3/8 to 2 or bigger and are easy to install with tools most people already own. Making sure you have a nice square cut and that you remove any burrs created while cutting is imperative. these fitings can be used on PVC, PEX, CPVC, PolyB, copper, and certain galvanized sizes. If youre stuck gluing, make sure you are using a proper primer before you apply the cement to the pipe and leave the pipe de-pressurized as long as possible. You can also try using a non flaming heat gun from a safe distance ( glue and primer are extremely flammable) so as to speed the curing up while not damaging the pipe or causing a fire or explosion. hope this helps :) Roland
