WebPorosity is the percentage of void space in a rock. It is defined as the ratio of the volume of the voids or pore space divided by the total volume. It is written as either a decimal fraction between 0 and 1 or as a percentage. For most rocks, porosity varies from less than 1% to 40%. The porosity of a rock depends on many factors, including ... WebAug 21, 2024 · THE H20 TEST: To determine your hair porosity level using water, spritz a small section of curls with water and watch how your hair reacts – does your hair absorb the water quickly (indicating high porosity) or does it remain on top (indicating a low porosity level)? Now that you know what your hair porosity is let’s move onto the fun stuff. mysql alter non string type not supported

WebApr 11, 2024 · The results showed that the elastic modulus decreased as a function of porosity level in all simulated materials. The TTM, TT and TTS foams, with average porosities of 20, 30 and 40%, exhibited an elastic modulus smaller than 30 GPa, which is a requirement to be used as biomaterial in human bones. WebTake a section and spritz it, then watch how the water absorbs. If the drops sit on the hair, it has low porosity, if it absorbs slowly, it has medium porosity, and if it absorbs quickly, it … WebDownload scientific diagram Average total porosity level and least-significant difference test results between groups. *p < 0.05, ** p > 0.05. from publication: Addition of gourami (Osphronemus ... the spica star
