A reference system for cortisol

Clinical Biochemistry, 1998
The International Federation of Clinical Chemistry (IFCC) initiated a pilot study, with cortisol as an example, that aims to implement the concept of standardization of hapten immunoprocedures on the basis of metrological traceability. In fact, this standardization concept comes down to correct calibration of measurement procedures, so that measurement

Reference systems and gravitation

International Journal of Theoretical Physics, 1971
It is shown how the formalism of the tetrad theory of gravitation used by Treder (1967a, b, 1970) follows from the more general fibre bundle formalism. This is of interest in the study of the relations between tetrad theories and the general theory of relativity.

A reference system for ionized calcium

Scandinavian Journal of Clinical and Laboratory Investigation, 1983
Reference systems in clinical chemistry, whether loosely structured or highly organized like the National Reference System for Clinical Chemistry (NRSCC) in the USA are built upon an assemblage of interrelated materials, methods, and agreements. For example, the NRSCC Council has accepted the following items for the measurement of total calcium in ...

Reference systems and their origins

Physics Essays, 2020
It is demonstrated how the choice of a reference system origin influences our interpretation of the natural laws. Instead of placing it arbitrarily as is customary in mechanics, we locate it at an energy minimum, or zero point of material systems. In an example from celestial mechanics, the sun defines the point of minimum gravitational potential and ...

Quantum reference systems

Classical and Quantum Gravity, 1991
The author argues that only by taking into account the quantum properties of the bodies that form the reference frames, physical quantum operators can be defined in quantum gravity. The theory of general relativity coupled to matter introduced in a companion paper is considered.

Information Systems as a Reference Discipline

MIS Quarterly, 2002
The conventional wisdom amongst information systems (IS) researchers is that information systems is an applied discipline drawing upon other, more fundamental, reference disciplines. These reference disciplines are seen as having foundational value for IS. We believe that it is time to question the conventional wisdom.

A reference pricing system for Ireland

Expert Review of Pharmacoeconomics & Outcomes Research, 2012
The various cost containment measures that have been introduced over the past few years in Ireland to contain pharmaceutical expenditure are well documented [1].

The National Reference System for Cholesterol

Clinics in Laboratory Medicine, 1989
The NRS/CHOL is a reality that is progressively becoming the way in which accuracy of cholesterol results is being ensured. Proof of traceability to NRS/CHOL within each segment of the clinical laboratory, now an expectation, will soon be the norm that makes a sound conceptual reference system into an everyday reality that reaches into the many ...

Moving Reference Systems

2004
In Chap. 2 it was assumed that balance equations were referred to an observer at rest in an inertial system. In this chapter our intention is not to concentrate on the issues like existence of such a reference system or on the ideas of constructing such a system, rather we presume that there exists such a reference system relative to which the ...
