Mat Properties. The catalytic converter shell has to be designed in such a way as to provide the required mounting pressure for a given catalyst substrate and a given mat.

Sometimes a severely bloated stomach â along with constipation, nausea and vomiting â is due to a bowel obstruction, which is caused by scar tissue or a tumor. When these grow and press against the bowel, the bowels become blocked and hold in fluid and stool.
Most cases of stomach bloating are due to improper diet. Gas occurs because of the bacteria in the colon and is a by-product of soluble fiber digestion. Inadequate or irregular intake of fiber and water will cause a person to experience bloating or constipation.
