Mohs scale of mineral hardness integrity, they are not considered "scratches" for the determination of a Mohs scale number. The Mohs scale is a purely ordinal scale. For example, corundum (9) is twice as hard as topaz (8), but diamond (10) is four times as hard as corundum. The table below shows the comparison with the absolute hardness measured by a sclerometer, with pictorial examples. On the Mohs scale, a streak plate (unglazed porcelain) has a hardness of approximately 7.0. Using these ordinary materials of known hardness can be a simple way to approximate the position of a mineral on the scale. The table below
Neonatal Behavioral Assessment Scale supposed to assess the "infant's role in the mother-infant social relationship" from which high scores are supposed to presume "high levels of intelligence.". Therefore, the value of the test is as a research tool and a supplement test to medical testing procedures. But as a predictor of future intelligence, it is very unsatisfactory. Because of this, some wonder what the scale is really measuring. Training is necessary for effective and reliable administration of the NBAS. Neonatal Behavioral Assessment Scale The Neonatal Behavioral Assessment Scale (NBAS), also known as the Brazelton Neonatal Assessment Scale (BNAS), was developed in 1973 by Dr.
