State-specific sciences relationship between

Tart, Science, 1972, 176 1203-1210, by permission of the American Association for the Advancement of Science) demonstrates some possible relationships between three state-specific sciences. State-specific sciences 1 and 2 show considerable overlap. 

The National Research Council/National Academy of Sciences of the United States recently concluded that there is a clear relationship between musculoskeletal disorders and work and between ergonomic interventions and a decrease in such disorders. According to the Academy, research demonstrates that specific interventions can reduce the reported rate of musculoskeletal disorders for workers who perform high-risk tasks (National Research Council 1998). The effective and universal standard for dealing with the work-related hazards should significantly reduce the risk to WRMDS to employees. 

The second part of the book compiles some practical aspects of metal oxides, with emphasis in catalytic applications. Metal oxides represent an expanding class of compounds with a wide range applications in several areas such as materials science and catalysis, chemical sensing, microelectronics, nanotechnology, environmental decontamination, analytical chemistry, solid-state chemistry, and fuel cells. Our basic knowledge on the metal oxide chemistry is relatively far from that for metals, and as yet, little is known about fundamental relationships between reactivity of oxide compounds and their chemical compositions, crystal structures, and electronic properties at the surface. When examining the importance of metal oxides, and specifically TMOs, in several reactions such as dehydration, selective oxidations, olefin metathesis, VOCs removal, photocatalysis, water splitting, and electrocatalysis, attempts will be made in order to connect properties of the oxides and their reactivity. Since the catalytic phenomenon is confined to the external surface of the solids where molecules or atoms interact, the study of this interaction... 

The definition authorizes the use of traceability in the specialized language of measurement science. Since the result of every measurement is a value, all traceability relationships are between values. Undoubtedly, these values are expected to be multiples or sub-multiples of a specific SI unit - or other internationally recognized unit quantity or ratios of unit quantities. A specific reference to a standard is always required and the result of every measurement in a traceability chain must be stated, referenced or clearly understood. It must be assumed (although in the definition it is not explicitly stated) that for each pair of traceable values as well as for the uncertainties of all comparisons in the relevant chain, these values are stated in terms of the identical unit quantity or of ratio of quantities.
