Thermal conductivity common use in the construction and textile industries. The construction industry makes use of units such as the R-value (resistance) and the U-value (transmittance). Although related to the thermal conductivity of a material used in an insulation product, R- and U-values are dependent on the thickness of the product. Likewise the textile industry has several units including the tog and the clo which express thermal resistance of a material in a way analogous to the R-values used in the construction industry. There are a number of ways to measure thermal conductivity. Each of these is suitable for a limited range
The Measure of a Man: A Spiritual Autobiography The Measure of a Man: A Spiritual Autobiography The Measure of a Man: A Spiritual Autobiography is an autobiographical work by Sidney Poitier.
