Gemstone Hardness The Mohs scale of mineral hardness was created by German mineralogist, Friedrich Mohs, in 1822 to measure the relative hardness or scratch resistance of various minerals. He based it on ten readily available minerals.
What ASCs Are Not. ASCs are not rural health clinics, urgent care centers or ambulatory care centers that provide diagnostic or primary health care services. ASCs treat only patients who have already seen a health care provider and selected surgery as the appropriate treatment for their condition. ASCs are not physicians' offices either.
Ambulatory surgery centers are free-standing facilities with operating rooms, but they are not hospitals. These centers perform procedures that allow the patient to recover at home once anesthesia has worn off and the patient is able to care for themselves with minimal assistance.
