Mohs scale of mineral hardness finding the hardest material that the given material can scratch, or the softest material that can scratch the given material. For example, if some material is scratched by apatite but not by fluorite, its hardness on the Mohs scale would fall between 4 and 5. "Scratching" a material for the purposes of the Mohs scale means creating non-elastic dislocations visible to the naked eye. Frequently, materials that are lower on the Mohs scale can create microscopic, non-elastic dislocations on materials that have a higher Mohs number. While these microscopic dislocations are permanent and sometimes detrimental to the harder material's structural
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.
