Scratching scale
WebHardness (H) is the resistance of a mineral to scratching. It is a property by which minerals may be described relative to a standard scale of 10 minerals known as the Mohs scale of hardness. The degree of hardness is determined by observing the comparative ease or difficulty with which one mineral is scratched by another or by a steel tool. For measuring … Web"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 …

WebScaling is an important secondary lesion in dermatology. The word scale is derived from skal ( Old English - Scealu; Old French - escale; or French - ιcaille - shell; Latin - Squama - a scale or plate-like structure). [2] Gentle scratching and rubbing alters visibility of scaling. WebTo actually explore the scales and modes through the shaping and transformation of rhythmically and melodically interesting tone patterns, we propose a playing technique called Fourier Scratching. It is based on the manipulation of the “spectra” (DFT) of playing gestures on a sphere.
