Biosystems, 1976
A theoretical study on evolution has been carried out, with the aim of disproving some value judgements essentially represented by the idea that the degree of evolution can increase. Our conclusions are based upon the preliminary statement that efficiency of survival is directly related to regulative ability.

New Units for the Measurement of Radioactivity
The Journal of Chemical Physics, 1946It has become the custom to express the strength of radioactive sources in terms of curies. This is an erroneous use of this unit since by original definition the curie is that “amount of radon in equilibrium with one gram of radium”* as defined by the Radiology Congress in Brussels in 1910.

Units of measure is the language of home energy information. We talk about our energy consumption in terms of specific units used to measure the consumption. Measuring is a vital part of the home energy information cycle. It is what guides us toward the actions we need to take in order to conserve energy and protect the environment.

Standardizing Units of Measurements
JAMA: The Journal of the American Medical Association, 1976Quantitative measurements are indispensable in the conduct of science. This is as true for medicine as it is for chemistry or physics. The close interrelationships between the many branches of science and the international character of science and medicine require that a single, worldwide system of measurements be employed.

SI units in radiation measurement [PDF]
The British Journal of Radiology, 1972 In October 1971, the Council of the European Community ratified a directive on units and measurements (EEC, 1971) which provides for the exclusive use by January 1, 1978 of a prescribed system of metric units. This system is firmly based on the International System (SI) as agreed by the General Conference of Weights and Measures, and its strict ...
