Shore durometer °Sh or >90 °Sh the results are not to be trusted. The measurement must be redone with adjacent scale type. Durometer is a dimensionless quantity, and there is no simple relationship between a material's durometer in one scale, and its durometer in any other scale, or by any other hardness test. Using linear elastic indentation hardness, a relation between the ASTM D2240 hardness and the Young's modulus for elastomers has been derived by Gent and by Mix and Alan Jeffrey Giacomin. Gent's relation has the form where formula_2 is the Young's modulus in MPa and formula_3 is the ASTM D2240
4th Shore the 4th Shore - "Quarta Sponda" - because of the large community of Tunisian Italians living there. During less than thirty years (1912–1940) in Libya the Kingdom of Italy (in the territory that was called initially Italian North Africa (1912–1934) and later Italian Libya (1934–1940) or 4th Shore of Greater Italia) developed the cities and countryside with an enormous array of investments. They built huge public works, such as new town districts with streets and buildings, modern ports, the Italian Libya Railways, and long highways. The Libyan economy and trade flourished very much, similar to what happened during the ancient
