Development of Metrology for Modern Biology

Modern Approaches in Phase Measuring Metrology

The measurement accuracy of an interferometric optical test is generally limited by the environment. This paper discusses two single-shot interferometric techniques for reducing the sensitivity of an optical test to vibration; simultaneous phase-shifting interferometry and a special form of spatial carrier interferometry utilizing a micropolarizer phase-shifting array. In both techniques averag...

The development of modern metrology and its role today.

Modern metrology is the result of more than 200 years of development that began with the creation of the decimal metric system at the time of the French Revolution and the beginning, at about the same time, of mass production using interchangeable parts. This article traces these developments and describes how world metrology is organized today and gives examples of applications of metrology sh...

Speleotherapy – modern bio-medical perspectives

UNLABELLED Speleotherapy - a special form of climatotherapy - uses certain conditions specific to caves and salt-mines to treat several medical conditions, especially respiratory and skin-related. This reduces all types of irritations and therefore disease symptoms are mitigated or fully suppressed while the patient is accommodated into the salt-mine. OBJECTIVE Influence of microclimate in sa...

Modern Perspectives in Child Psychiatry

Edited by J. G. How ells (Oliver & Boyd, 1965, ?5 5s.) This is a formidable and weighty book in every sense of the word. Twenty*sl* contributors have written twenty-four chapters on widely different topics, to up a book of 595 large, closely printed pages. This is not, therefore, a book whic11 one sits down and reads through. The reader is more likely to choose a chaptet here and there, in term...
