23Digital artifactual value — is a preservation term that refers to the intrinsic value of a digital object, rather than the informational content of the object. There are currently no established standards for what constitutes digital artifactual value. Nonetheless, born… …
24Building insulation materials — A selection of insulation materials can aid in building insulation. All of these are based on standard principles of thermal insulation. Materials used to reduce heat transfer by conduction, radiation or convection are employed in varying… …
25Labor theory of value — The labor theories of value (LTV) are theories in economics according to which the values of commodities are related to the labor needed to produce them.There are many different accounts of labor value, with the common element that the value of… …
26R-value (insulation) — The R value or R value is a measure of thermal resistance (K·m²/W) [Oak Ridge National Laboratory, [http://www.ornl.gov/sci/roofs+walls/insulation/ins 02.html Which Kind Of Insulation Is Best?] , retrieved 2008 07 13.] used in the building and… …
27Strength of materials — Internal force lines are denser near the hole, a common stress concentration In materials science, the strength of a material is its ability to withstand an applied stress without failure. The applied stress may be tensile, compressive, or shear …

29Ceramic materials — Ceramic Si3N4 bearing parts Ceramic materials are inorganic, non metallic materials and things made from them. They may be crystalline or partly crystalline. They are formed by the action of heat and subsequent cooling.[1] Clay was one of the… …
30Certified reference materials — (CRMs) are ‘controls’ or standards used to check the quality and traceability of products. A reference standard for a unit of measurement is an artifact that embodies the quantity of interest in a way that ties its value to the reference base for …
