EX: Rated 1-A:10-B:C what's the 1 and 10 for ?
Yes he can legally rent a unit in that condition. If he will not fix the window and you do not have the money to do so on your own, cover it with cardboard to keep the cold out. Good Luck
Lightening rods are often higher than the building. Ligntening rods are more conductive than the building.
At present, stated CD-R lifetimes are only estimates based on accelerated aging tests as the technology has not been in existence long enough to verify the upper range. With proper care it is thought that CD-Rs should be readable one thousand times or more and have a shelf life of several hundred years. Unfortunately, some common practices can reduce shelf life to only one or two years. Therefore, it is important to handle and store CD-Rs properly if it is necessary to read them more than a year or so later. Burned CD-Rs suffer from material degradation, just like most writable media. Optical discs commonly used for burning, such CD-R and CD-RW have a recording surface consisting of a layer of dye that can be modified by heat to store data. The degradation process can result in the data shifting on the surface and thus becoming unreadable to the laser beam. As well as degradation of the dye, failure of a CD-R can be due to the reflective surface. While silver is cheaper and more widely used, it is more prone to oxidation resulting in a non-reflecting surface. Gold on the other hand, although more expensive and hard to find on a CD-R, is an inactive material and so, gold based CD-R's do not suffer from this problem. Permanent markers are commonly used to mark the label side of CD-Rs and DVDs. This practice has been discouraged because it is believed xylene and toluene, common substances in permanent marker ink, can cause surface deterioration. Additionally, volatile organic compounds may be released which will remain inside the enclosed atmosphere of a CD-R's storage box, causing harm. One last factor that affects the quality of a CD-R and influences its lifespan is the lacquer that is used to seal the CD-R and protect the dye and the reflective material from the influence of external materials (air, water, alcohol, etc).
Rejoice! they last forever!(unless they feel the wrath of the pointy edges!) be warned tho that when in 4000 years archiologists dig up the remains of your pics they had better be good ;p seriously tho the only other secure ways to store them are on a DVD or on the memory card they originaly came from.
