# Nodal Sentence Examples

- It is found that the direction of the moon's equator remains nearly invariable with respect to the plane of the orbit, and therefore revolves with that plane in a
**nodal**period of 18.6 years. - The best known of these are Jose Sebastian Barranca, the naturalist and antiquary, Jose Fernandez
**Nodal**, and Gavino Pacheco Zegarra of Cuzco, who published translations of the Inca drama of 011antay, and Leonardo Villar, of Cuzco. - Io) represents the displacement curve of a train of waves, will represent the pressure excess and particle velocity, and from (II) we see that while the
**nodal**conditions of b, with Co' and u=o, travel with velocity 1/(E/p), the crests exceed that velocity by 1(7 + i)u, and the hollows fall short of it by 1(7 + I)u, with the result that the fronts of the pressure waves become steeper and steeper, and the train b changes into something like c. If the steepness gets very great our investigation ceases to apply, and neither experiment nor theory has yet shown what happens. - The flame there is much H K' L affected by the
**nodal**pressure changes, while the other two vibrate only slightly. - The plate is then bowed at the edge and is thrown into vibration between
**nodal**lines or curves and the sand is thrown from the moving parts or ventral segments into these lines, forming " Chladni's figures." - As in the case of a musical string, so here we find that the pitch of the note is higher for a given plate the greater the number of ventral segments into which it is divided; but the converse of this does not hold good, two different notes being obtainable with the same number of such segments, the position of the
**nodal**lines being, however, different. - If the plate be small, it is sufficient, in order to bring out the simpler sand-figures, to hold the plate firmly between two fingers of the same hand placed at any point where at least two
**nodal**lines meet, for instance the centre in (1) and (2), and to draw a violin bow downwards across the edge near the middle of a ventral segment. - But with larger plates, which alone will furnish the more complicated figures, a clamp-screw must be used for fixing the plate, and, at the same time, one or more other
**nodal**points ought to be touched with the fingers while the bow is being applied. - By similar methods, a circular plate may be made to exhibit
**nodal**lines dividing the surface by diametral lines into four or a greater, but always even, number of sectors, an odd number being incompatible with the general law of stationary waves that the parts of a body adjoining a**nodal**line on either side must always vibrate oppositely to each other. - Circular
**nodal**lines unaccompanied by intersecting lines cannot be produced in the manner described; but may be got either by drilling a small hole through the centre, and drawing a horse-hair along its edge to bring out the note, or by attaching a long thin elastic rod to the centre of the plate, at right angles to it, holding the rod by the. - During the quarter swing ending with greatest
**nodal**pressure, the kinetic energy is changed to potential energy manifested in the increase of pressure. - Let, now, the plate be made in the usual manner to vibrate so as to exhibit two
**nodal**lines coinciding with two rectangular diameters. - On germination it gives rise to a row of cells in which short (
**nodal**) and long (internodal) cells alternate. - In 1619 the brothers Garcia and Gongalo de
**Nodal**first circumnavigated the archipelago, which was afterwards visited at intervals by Captain Sir John Narborough (1670), M. - It is to be remarked that the classification mixes together non-singular and singular curves, in fact, the five kinds presently referred to: thus the hyperbolas and the divergent parabolas include curves of every kind, the separation being made in the species; the hyperbolisms of the hyperbola and ellipse, and the trident curve, are
**nodal**; the hyperbolisms of the parabola, and the cubical parabola, are cuspidal. - We have herein a better principle of classification; considering cubic curves, in the first instance, according to singularities, the curves are non-singular,
**nodal**(viz. - The analogous question of the classification of quartics (in particular non-singular quartics and
**nodal**quartics) is considered in Zeuthen's memoir " Sur les differentes formes des courbes planes du quatrieme ordre " (Math. - And so if D =2, then the transformed curve is a
**nodal**quartic; 4 can be expressed as the square root of a sextic function of 0 and the theorem is, that the co-ordinates x, y, z of a point of the tricursal curve can be expressed as proportional to rational and integral functions of 0, and of the square root of a sextic function of 0. - The common casts of Calamites are of this nature, representing the form of the hollow medulla, and bearing on their surface the print of the
**nodal**constrictions and of the ridges and furrows on the inner surface of the wood. - In the third-order complex the centre locus becomes a finite closed quartic surface, with three (one always real) intersecting
**nodal**axes, every plane section of which is a trinodal quartic. The chief defect of the geometrical properties of these bi-quaternions is that the ordinary algebraic scalar finds no place among them, and in consequence Q:1 is meaningless.
