For small minerals, I use small cups.
Osteoporosis T-Score: Do I Have a Normal Bone Density?
T-scores between -1 and -2.5 indicate that a person has low bone mass, but it's not quite low enough for them to be diagnosed with osteoporosis. A diagnosis of osteoporosis is made if a person's T-score is -2.5 or lower. The lower a person's T-score, the more severe their bone loss is, and the more at risk for fractures they are.

From the Navier-Stokes equation (Equation 1), it can be seen that flow behaviour is directly determined by two key fluid properties- density and dynamic viscosity. CFD studies of ...
Hydroxyapatite Dental Material
Hydroxyapatite (HA) was the primary material used in orthopedics and dentistry. HA is an inorganic mineral that has a typical apatite lattice structure as (A10 (BO4)6C2), where A, B, and C are defined by Ca, PO4, and OH. Pure HA contains 39.68% by weight calcium and 18% by weight phosphorus, resulting in a Ca/P mole ratio of 1.67.
Physical Properties of Minerals » Geology Science
Some of the common physical properties of minerals include: Hardness: Hardness refers to the ability of a mineral to resist scratching. The Mohs scale of hardness, which ranges from 1 (the softest) to 10 (the hardest), is commonly used to measure the hardness of minerals. For example, talc has a hardness of 1, while diamond, the hardest …
