TIFF is a computer file format for storing raster graphics images, popular among graphic artists, the publishing industry, and both amateur and professional photographers in general. The format was originally created by the company Aldus for use in desktop publishing.
Today, pygeum is primarily used as a treatment for benign prostatic hyperplasia (BPH), or prostate enlargement.The evidence in support of this use is no more convincing than the evidence in support the more famous, natural BPH remedy, saw palmetto.cknowledging these limitations, pygeum may reduce symptoms, such as nighttime urination, urinary frequency, and residual urine volume. Besides BPH, pygeum is also sometimes proposed for prostatitis, as well as impotence and male infertility; 1,2 however, there is little real evidence that it works for these conditions.
The semiconductor material used in devices is doped under highly controlled conditions in a fabrication facility, or fab, to control precisely the location and concentration of p-and n-type dopants. The junctions which form where n-type and p-type semiconductors join together are called pân junctions.ermanium (Ge) was a widely used early semiconductor material but its thermal sensitivity makes it less useful than silicon. Today, germanium is often alloyed with silicon for use in very-high-speed SiGe devices; IBM is a major producer of such devices.
