Metrological Traceability of Measurement Results in Chemistry
In commerce, society, and science, metrological comparability of measured quantity values and various published values is essential to determine their spatio-temporal differences, ratios, and drifts. Achieving metrological comparability of measurement results requires definition of calibration hierarchies providing metrological traceability chains which enable the establishment of metrological traceability of measured quantity values to a common metrological reference.
Experience has shown that the understanding of the concepts involved, their relation, role, definition, and use is insufficient and varied. Consequently, an attempt is made in this study to arrive at a set of consistent concept systems with associated terminology for measurement in chemistry. The systems build on definitions of concepts and associated terms from the new 3rd edition (2007) of the International Vocabulary of Metrology—Basic and General Concepts and Associated Terms, such as quantity, measurand, calibration, measurement procedure, measurement uncertainty, measurement standard, calibrator, and reference material. Additional concepts such as metrological equivalence of measurement results are also given.
Flow charts of generic calibration hierarchies are presented as well as a variety of examples.
The establishment, assessment, and reporting of metrological traceability are discussed, including the needed metrological institutional hierarchy and the role of interlaboratory comparisons.
Recommendations are made about the essential steps in planning and performing a measurement, and reporting a measurement result.

Glossary of Terms Used in Pharmaceutics
This Glossary of Terms in Pharmaceutics is needed by practitioners in the field of pharmaceutics—a field that fulfills an important and crucial role, different from the roles of other scientific disciplines involved in the drug-making process. The glossary contains 156 definitions used in pharmaceutics. These are related to various aspects of this discipline such as 1) physicochemical characterization of pharmaceutical preparations and the active ingredients they contain; 2) unit operations used in the practice of pharmaceutics; 3) terms related to the various dosage forms; 4) terms related to the various modes and routes of drug delivery; and 5) terms used in pharmacokinetics and biopharmaceutics in general, and additional miscellaneous terms. Since the field of pharmaceutics is multidisciplinary, with practitioners from a variety of fields such as chemistry or various biological sciences, a glossary containing authoritative definitions would be useful to them. The terms used in pharmaceutics are rarely covered by existing glossaries, and in cases were they are, their definitions are often inappropriate for the field of pharmaceutics and require new or modified definitions to better fit the new context.
