At barometric pressures such as exist between 18 and 36 kilometres above the ground the mobility of the ions varies inversely as the pressure, whilst the coefficient of recombination a varies approximately as the pressure.
A better basis of comparison would be the ratio of the actual to the limiting conductivity, but since the conductivity of acids is chiefly due to the mobility of the hydrogen ions, its limiting value is nearly the same for all, and the general result of the comparison would be unchanged.
In the floor of the mouth, between the two branches of the lower jaw, and supported behind by the hyoid apparatus, lies the tongue, an organ the free surface of which, especially in its posterior part, is devoted to the sense of taste, but which by reason of its great mobility (being composed almost entirely of muscular fibres) performs important mechanical functions connected with masticating and procuring food.
It depends, however, in addition on the natural mobility of the ions, and also on the opportunities for convection.
The strength of the army lay in its infantry, for both cavalry and artillery were short of horses, and the latter had not yet acquired mobility and skill in manoeuvring.
The atmosphere, because of its great tenuity, mobility and comparative imponderability, presents little resistance to bodies passing through it at low velocities.
Its perfection would, nevertheless, be undermined by the mobility of all its constituent parts.
As a soldier Tarnowski invented a new system of tactics which greatly increased the mobility and the security of the armed camps within which the Poles had so often to encounter the Tatars.
It is therefore less than the motion in an absolutely rigid spheroid in the proportion RP': RP. It is found that, even though the earth were no more elastic than steel, its yielding combined with the mobility of the ocean would make this ratio about 2 :3, resulting in an increase of the period by one-half, making it about 457 days.
The conductivity, which varies as the product of n into the mobility, will thus vary inversely as the pressure, and so at 36 kilometres will be one hundred times as large as close to the ground.
Their strength had been their mobility and their undisputed command of the sea.
In deriving a period of 305 days the earth is regarded as an absolutely rigid body, and no account is taken either of its elasticity or of the mobility of the ocean.
But it is obvious that if the assumption of perfect mobility is invalid, there is scarcely any economic doctrine identified with the earlier writers which may not require modification, in what degree it is impossible to say without very careful investigation.
38) gives a faithful representation of the great mobility of the various parts of the body.
They were normally drawn up in more open order than the heavy Greek phalanx, and possessed thereby a mobility and elasticity in which the latter was fatally deficient.
Here the superiority of French mobility, a consequence of their training and not necessarily of their system, showed its value most conclusively.
The want of mobility, particularly in the cavalry, now began to tell against the French.
Though he had control of what remained of the navies of Holland and Spain, as well as of the French, he was outnumbered at every point, while the efficiency of the British fleet gave it a mobility which doubled its material superiority.
By his mode of regarding a liquid as a material system characterized by the unshackled mobility of its minutest parts, the separation between the mechanics of matter in different forms of aggregation finally disappeared, and the fundamental equation of forces was for the first time extended to hydrostatics and hydrodynamics.'
Its causes and results are fundamental for the study of ethnology (formation and mixture of races), of political and social history (formation of states and survival of institutions), and of political economy (mobility of labour and utilization of productive forces).
The constriction of this segment and its very perfect articulation with the propodeum give great mobility to the abdomen, so that the ovipositor or sting can be used with the greatest possible accuracy and effect.
The extraordinary mobility of his whole person, and his power of as it were transforming himself at will, are attested by many anecdotes and descriptions, but the piercing power of his eye must have been his most irresistible feature.
He might thus compensate for his numerical inferiority by superior mobility and superior leadership.
As already mentioned, all efforts to assimilate optical propagation to transmission of waves in an ordinary solid medium have failed; and though the idea of regions of intrinsic strain, as for example in unannealed glass, is familiar in physics, yet on account of the absence of mobility of the strain no attempt had been made to employ them to illustrate the electric fields of atomic charges.
More recently a way has been pointed out in which a mobile permanent field of electric force could exist% in such a medium so as to travel freely in company with its nucleus or intrinsic charge - the nature of the mobility of the latter, as well as its intimate constitution, remaining unknown.
Bugeaud resolutely adopted the offensive, reduced the weight carried by the soldiers in order to increase the mobility of his troops, and carried the war into the province of Oran, from which Abd-el-Kader drew his principal resources.
On this point it must be borne in mind that the population of the larger towns, on account of the greater mobility of the population since the introduction of railways and the abolition of restrictions upon free settlement, has become more mixedBerlin, Leipzig, Hamburg, &c., showing proportionally more Roman Catholics, and Cologne, Frankfort-onMain, Munich more Protestants than formerly.
A sandy beach or desert owes its character to the mobility of its constituent sand-grains, which are readily drifted and piled up in the form of dunes.
Had the Austrians possessed mobility equal to that of the French the latter should have been overwhelmed in detail, but whilst the French covered 17 and 19 m.
Lankester, " Mobility of the Spermatozoa of Limulus," Quart.
Finally, ample scope for the display of tolerance - or intolerance - is found in the mixed marriages between Protestants and Catholics, which, as a result of the modern facilities for intercommunication and the consequent greater mobility of the population, have shown a large increase during the last few decades - in Germany, for instance.
