Thunder.-Trustworthy frequency statistics for an individual station are obtainable only from a long series of observations, while if means are taken from a large area places may be included which differ largely amongst themselves.
Metallic yttrium is obtainable as.
Nearly all the information now obtainable is to be found in the following works and such as are there quoted: S.
It is obtainable from most natural fatty bodies by the action of alkalis and similar reagents, whereby the fats are decomposed, water being taken up, and glycerin being formed together with the alkaline salt of some particular acid (varying with the nature of the fat).
There are no figures obtainable as to the production, but it must be very large, considering that the crop provides clothing for a large proportion of the population of China.
It was long supposed that the simplest ring obtainable contained six atoms of carbon, and the discovery of trimethylene in 1882 by August Freund by the action of sodium on trimethylene bromide, Br(CH 2) 3 Br, came somewhat as a surprise, especially in view of its behaviour with bromine and hydrogen bromide.
Baeyer pointed out that although benzene derivatives were obtainable from hexamethylene compounds, yet it by no means follows that only hexamethylene compounds need result when benzene compounds are reduced.
The figures obtainable with respect to shipping are approximate, the statistical data not being altogether complete.
Promotion was regular, but was obtainable only by entering at an early age one of the medresses or colleges; the student, after passing through the successive degrees of danishmend, mulazim and muderris, became first a molla, then a judge, rising to the higher ranks as fortune and opportunity offered.
Prawns, crayfish and oysters are also obtainable, and turtle (Chelonia mydas) are frequently captured.
Frankincense has always been obtainable in Europe in greater quantity than any other of the aromatics imported from the East; it has therefore gradually come to be the only incense used in the religious rites and domestic fumigations of many countries of the West, and at last to be properly regarded as the only "true" or "genuine" (i.e.
If double-bottomed defecators are used in sufficient number to allow an hour and a half to two hours for making each defecation, and if they are of a size which permits any one of them to be filled up by the cane-mill with juice in ten to twelve minutes, they will make as perfect a defecation as is obtainable by any known system; but their employment involves the expenditure of much high-pressure steam (as exhaust steam will not heat the juice quickly enough through the small surface of the hemispherical inner bottom), and also the use of filter presses for treating the scums. A great deal of skilled superintendence is also required, and first cost is comparatively large.
In Nejd the number of horses is, comparatively speaking, very small; the want of water in the Nafud where alone forage is obtainable, and the absence of forage in the neighbourhood of the towns makes horse-breeding on a large scale impracticable there.
In explanation of the fact that he did not essay this route in former times, it may be noted, first, that he had only a limited acquaintance with the wares in question; secondly, that Japanese connoisseurs never attached any value to their countrymens imitation of Chinese porcelains so long as the originals were obtainable; thirdly, that the ceramic art of China not having fallen into, its present state of decadence, the idea of competing with it did not occur to outsiders; and fourthly, that Europe and America had not developed their present keen appreciation of Chinese masterpieces.
The balance of work obtainable in such a cycle depends on the limits of temperature in a manner which forms the subject of the second law.
- Carnot adopted as the analytical expression of his principle the statement that the efficiency W/H, or the work obtainable per unit of heat by means of a perfect engine taking in heat at a temperature t° C. and rejecting heat at o° C., must be some function F(t) of the temperature t, the lower limit o° C. being supposed constant.
He therefore employed the corresponding expression for a cycle of infinitesimal range dt at the temperature t in which the work dW obtainable from a quantity of heat H would be represented by the equation dW =HF'(t)dt, where F'(t) is the derived function of F(t), or dF(t)/dt, and represents the work obtainable per unit of heat per degree fall of temperature at a temperature t.
The increment of this area (or the decrement of the negative area E--04) at constant temperature represents the external work obtainable from the substance in isothermal expansion, in the same way that the decrement of the intrinsic energy represents the work done in adiabatic expansion.
These functions do not, however, represent energy existing in the substance, like the intrinsic energy; but the increment of 90 represents heat supplied to, and the decrement of (E-04) represents work obtainable from, the substance when the temperature is kept constant.
Before the commercial production of calcium carbide made it one of the most easily obtainable gases, the processes which were most largely adopted for its preparation in laboratories were: - first, the decomposition of ethylene bromide by dropping it slowly into a boiling solution of alcoholic potash, and purifying the evolved gas from the volatile bromethylene by washing it through a second flask containing a boiling solution of alcoholic potash, or by passing it over moderately heated soda lime; and, second, the more ordinarily adopted process of passing the products of incomplete combustion from a Bunsen burner, the flame of which had struck back, through an ammoniacal solution of cuprous chloride, when the red copper acetylide was produced.
In early districts seeding may take place as early as February, provided a fine tilth is obtainable, but it rarely extends beyond the end of April.
Similar results are obtainable by means of the remaining perforations.
On the Pacific coast, where excellent timber is obtainable and steel works are distant, combination bridges are still largely used (Ottewell, Trans.
Meat is eaten, but, as the slaughter of animals is against Buddhist tenets, is not often obtainable, with the exception of pork, killed by Chinese.
Lastly, to allow for the superior centering of the shot obtainable with the breech-loading system, Bashforth introduces a factor a, called the coefficient of steadiness.
The usual route through Moscow could not be thought of, and the roundabout way Princess Mary was obliged to take through Lipetsk, Ryazan, Vladimir, and Shuya was very long and, as post horses were not everywhere obtainable, very difficult, and near Ryazan where the French were said to have shown themselves was even dangerous.
To lead men forward under fire more discipline (obtainable only by movement in masses) is needed than is needed to resist attacks.
