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.
Urgent care centers are distinguished from similar ambulatory healthcare centers such as emergency departments and convenient care clinics by their scope of conditions treated and available facilities on-site.
