The pyro-electric characters of quartz are closely connected with its peculiar type of symmetry and especially with the three uniterminal dyad axes.
Crystals of this class possess neither planes nor centre of symmetry, but only axes of symmetry: perpendicular to the principal triad axis there are three uniterminal dyad axes of symmetry.
When used together they work as a dyad and produce a lovely tropical feel that is light and airy.
The most important relationships are those between two people - forming the dyad.
Look at a map and see if you can find the DNA dyad.
The monad, which is opposed to the indefinite dyad, is just one of three gods for Numenius (Fr.
Can our individual narratives in relation to race, culture and attachment be unmasked in the therapeutic dyad to reveal our human connectedness?
We first describe the model of this exchange dyad and actors ' decision making with respect to behavior in a particular dyad.
Further work on the granodiorite dyad yielded no matches, and unless additional pieces are found, the work of reconstruction is essentially finished.
indefinite dyad, is just one of three gods for Numenius (Fr.
Below this first principle are a second one, which is also called the monad, and the indefinite dyad.
Thus if a ` third party ' should join the dyad the form changes and we do not perceive such immediate reciprocity.
unmasked in the therapeutic dyad to reveal our human connectedness?
Those elements which are equivalent in combining or displacing power to a single atom of hydrogen are said to be univalent or monad elements; whilst those which are equivalent to two atoms of hydrogen are termed bivalent or dyad elements; and those equivalent to three, four, five or six atoms of hydrogen triad, tetrad, pentad or hexad elements.
Thus, it must be supposed that in nitric oxide, NO, an odd number of affinities are disengaged, since a single atom of dyad oxygen is united with a single atom of nitrogen, which in all its compounds with other elements acts either as a triad or pentad.
The oxide NO 2 must be regarded as another instance of a compound in which an odd number of affinities of one of the contained elements are disengaged, since it contains two atoms of dyad oxygen united with a single atom of triad or pentad nitrogen.
- Graphic or constitutional formulae are employed to express the manner in which the constituent atoms of compounds are associated together; for example, the trioxide of sulphur is usually regarded as a compound of an atom of hexad sulphur with three atoms of dyad oxygen, and this hypothesis is illustrated by the graphic formula 0=S`O.
Each of these OH groups is equivalent in combining or displacing power to a monad element, since it consists of an atom of dyad oxygen associated with a single atom of monad hydrogen, so that in this case the S02 group is equivalent to an atom of a dyad element.
Thus, the atom of hydrogen is a monad simple radical, the atom of oxygen a dyad simple radical, whilst the group OH is a monad compound radical.
