The oldest fossils of multi-cellular animals we've found are over 600 million years old, so it took a little while to get where we are now. The eon covering the time from when animals really get going until now is called the Phanerozoic era (the era of well-defined or apparent life). Below are some highlights.
What is bariatric equipment. Simply put it is equipment and supplies that are designed for larger or obese patients. The term bariatric aids, or bariatric equipment, comes from the merging of two Greek words, baros which means weight and iatrics meaning medical treatment. Bariatric Equipment designs cater for the larger person and features increased weight capacities, heavy duty supports and wider widths to fit the persons needs.
Barium sulfate (or sulphate) is the inorganic compound with the chemical formula BaSO 4. It is a white crystalline solid that is odorless and insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it.lthough barium is a heavy metal, and its water-soluble compounds are often highly toxic, the low solubility of barium sulfate protects the patient from absorbing harmful amounts of the metal. Barium sulfate is also readily removed from the body, unlike Thorotrast, which it replaced.
