Acute hepatitis B is the period of illness that occurs during the first one to four months after acquiring the virus. Only 30% to 50% of adults develop significant symptoms during acute infection. Early symptoms may be non-specific, including fever, a flu-like illness, and joint pains. Symptoms of acute hepatitis may include: 1  fatigue, 2  loss of appetite, 3  nausea, 4  jaundice (yellowing of the skin and eyes), and.  pain in the upper right abdomen (due to the inflamed liver).
What is a Disc Tear? A disc or annular-tear (or fissure) represents a degenerative or traumatic change in an interveterbral disc1. These tears involve separations or breaks in the fibers comprising the annulus fibrosus, or the fibrous outer-most portion of an intervertebral disc.
Here is my explanation in simple form: An annular plate is a ring of plates that sit directly underneath the shell plate. The bottom plate sits inside the shell plate and is welded to the annular ring plates. On a tank that doesnt have an annular ring, the bottom plates will extend from underneath the tank shell. There are weld spacing and other dimensions that need to be adhered to, but this is the main difference between annular and bottom plates. Viewed 194 times. Published on ast-forum.com.
