Spin is a property of the atom’s elementary particles – electron, proton,
neutron – which consists in a rotation that imparts them kinetic energy.

Proton: Positively charged elementary atomic particle (mass: 1.6726 x 10-27 kg,
about 1836 times the mass of the electron; the proton is made of 3 quarks bound together
with an energy particle or gluon); the proton and the neutron make up the nucleus.
In a water molecule, the nuclei of the two hydrogen atoms have only one proton each and
no neutron whereas the oxygen atom nucleus is made up of eight protons with the eight matching neutrons.
In the prevailing experimental circumstances described here, the induced activation and therefore the
T measurements apply to the water hydrogen atoms protons.

Pulse: The magnetic field is applied continuously whereas radiofrequency waves are applied
in short duration bursts repeated at intervals, or pulses.

14.
Main components analysis: mathematical method of data analysis whereby the main data in a
table of quantitative variables measured on each members of a set may be taken out so that a
projection of the distance between individual members of the set considered may be obtained.

15.
Variance analysis: the reported experiment is a T2 variance analysis.
The deviations recorded depend upon parameters whose influence is being investigated;
some of these parameters e.g. lot, substance, dilution level, potentiation are under the
investigator’s control. The variance analysis helps in appreciating the actual influence of
these controlled parameters in T2 values variations.

T-related test: Statistic test applied whenever a parameter is measured in one series
of individuals or objects before and after a given action; it allows showing whether or not
the intervention is followed with significant variation in the parameter under study.

17.
Model: a model is one of the means whereby we may capture and represent reality.
The general notion of model includes those of approximate copy (a portrait or sculpture
of a varying measure of realism), principal part (that part of the whole invested with the
highest significance at a given moment in time), instrument in the way the hammer is instrumental
in driving a nail home. Here, we were confronted with deriving as our model a mathematical expression
we would use to describe the relationship between our experimental points.

Extrapolated curve:
a curve in which the values of a variable in an unobserved interval
are inferred from values within an already observed interval
|
20.
Continuous and monotonous: for a given interval, a uniform function varies continuously
without break in the same direction
|
21.
Regressive or progressive functions: according to the sign (negative or positive) of the
difference between two consecutive values, one would describe them as decreasing or increasing
