Modifications of the system have been adopted for bridges with discontinuous spans.
The discovery of this significant looped arrangement of the morainic belts is the greatest advance in interpretation of glacial phenomena since the first suggestion of a glacial period; it is also the strongest proof that the ice here concerned was a continuous sheet of creeping land ice, and not a discontinuous series of floating icebergs, as had been supposed.
To a mile) is dissected by many branching consequent streams; in its southernpart, as it ap~iroaches the Colorado river the cuesta is dissected into a belt of discontinuous hills.
As, in succeeding members of this same series of cast irons, more of the graphite of the initial skeleton changes into cementite and thereby becomes part of the metallic matrix, so the graphite skeleton becomes progressively thinner and more discontinuous, and the matrix richer in cementite and hence in carbon and hence equivalent first to higher and higher carbon steel, such as tool steel of I carbon, file steel of 1.50%, wire-die steel of 2% carbon and then to white cast iron, which consists essentially of much cementite with little ferrite.
A few writers have insisted that they are discontinuous, and that real gaps exist between them.
The Oligocene forms a band stretching from Antwerp to Maastricht, and this is followed towards the north by a discontinuous strip of Miocene and a fairly extensive area of Pliocene.
Triassic rocks form a discontinuous band along the northern coast, and are especially well developed in the neighbourhood of Palermo.
Discontinuous thermoscopes, depending on the fusion of a metal or salt, are also employed.
De Vries, have urged that as species are discontinuous - that is to say, marked off by structural differences of considerable magnitude - it is more probable that they have arisen from similarly discontinuous variations.
So far as magnitude is concerned, the attack on the Darwinian position has failed, and it is agreed that species may be discontinuous and none the less have been produced from minute variations.
The variations which de Vries has called mutations, and which were at first associated by Bateson with what he called discontinuous variations as the exclusive source of new species, are now supposed by de Vries to be distinguished from fluctuating variations by their mode of origin.
Since Hand Regulation Is Necessarily Discontinuous, The Speed And The Temperature Were Constantly Varying, So That It Was Useless To Take Readings Nearer Than The Tenth Of A Degree.
If PQ be a short segment containing an isolated load W, we have FeFi.=W, MQ=MP; (3) hence F is discontinuous at a p concentrated load, diminishing by an amount equal to the load as we pass the loaded point to the right, whilst M is continuous.
As it is unlikely that these delicate insects could be transported across seachannels, their wide and discontinuous range suggests both their great antiquity and the former existence of continental tracts over which they may have travelled to their present stations.
Front (left bank of the Tunja), was an advanced position, or rather a discontinuous series of field positions on selected sites astride the saddles of ground which separate the rivers (Tunja and lower Maritsa, Maritsa and Arda, Arda and upper Maritsa, upper Maritsa and Tunja).
Apart then from absorption there will be a discontinuous change in brightness in the apparent disk at that value of the angular radius d which corresponds to tangential emission from the upper lever r' of this mirage-forming region.
Then with an uniaxal plate perpendicular to the optic axis, the black cross is replaced by two lines, on crossing which the rings are discontinuous, expansion or contraction occurring in the quadrants that contain the axis of the quarter-wave plate, according as the crystal is positive or negative.
The longitudinal system is discontinuous, and is subdivided into proximal, medial and distal portions.
In this way we may distinguish, first, vegetative reproduction, the result of discontinuous growth of the tissues and cell-layers of the body as a whole, leading to (I) fission, (2) autotomy, or (3) vegetative budding; secondly, germinal reproduction, the result of the reproductive activity of the archaeocytes or germinal tissue.
Arithmetical groups, connected with the theory of quadratic forms and other branches of the theory of numbers, which are termed "discontinuous," and infinite groups connected with differential forms and equations, came into existence, and also particular linear and higher transformations connected with analysis and geometry.
Although this transition from the discontinuous to continuous is not truly scientific, yet it materially augmented the development of algebra, and Hankel affirms that if we define algebra as the application of arithmetical operations to both rational and irrational numbers or magnitudes, then the Brahmans are the real inventors of algebra.
A due appreciation of the far-reaching results of " correlated variation " must, it appears, give a new and distinct explanation to the phenomena which are referred to as " large mutations," " discontinuous variation " and " saltatory evolution."
In the simplest case the main girders are supported at the ends only, and if there are several spans they are discontinuous or independent.
Remarkable cases of discontinuous distribution are Chalarodon and Hoplodon in Madagascar, and Brachylophus fasciatus in the Fiji Islands.
Which is essentially based on a theory of interrupted or discontinuous characters, is inapplicable.
The essence of Waagen's law is orthogenesis, or evolution in a definite direction, and, if there does exist an internal hereditary principle controlling such orthogenetic evolution, there does not appear to be any essential contradiction between its gradual operation in the " mutations of Waagen " and its occasional hurried operation in the " mutations of de Vries," which are by their definition discontinuous or saltatory (Osborn, 1907).
This was based on the assumption that the medium in which the light is propagated is discontinuous and molecular in character, the molecules being subject to a mutual attraction.
Still more, it is discontinuous, because of the inclusion of certain belts of weak non-crystalline rock; here the rolling uplands are worn down to lowland belts, the longest of which reaches from the southern corner of New York, across New Jersey, Pennsylvania and Maryland, into central Virginia.
The graph will then be made up of a succession of parallel lines.
