I could go on and on about how adorable they are, but I've always been one for visuals. Here is a sample of our beginning of the year David project (as in David Shannon's. David Goes to School picture book). Enjoy.
PPIâs are drugs which reduce gastric acid production in the stomach. These are commonly prescribed for GERD and for gastric ulcers. According to Medicine-net.com this is how they work: proton pump inhibitors reduce the production of acid by blocking the enzyme in the wall of the stomach that produces acid.
Pixels per inch (ppi) - A measurement of image resolution that defines the size an image will print. The higher the ppi value, the better quality print you will get--but only up to a point. 300ppi is generally considered the point of diminishing returns when it comes to ink jet printing of digital photos. Dots per inch (dpi) - A measurement of printer resolution that defines how many dots of ink are placed on the page when the image is printed. Today's photo-quality ink jet printers have dpi resolution in the thousands (1200 to 4800 dpi) and will give you acceptable quality photo prints of images with 140-200 ppi resolution, and high quality prints of images with 200-300 ppi resolution.
