Within the trabeculae of the sponge-work blood circulates, and between the trabeculae the water passes,.
In these storms the wind invariably circulates from north by west through south to east.
5 the current is shown dividing round the two rings; but in all the balances, except those intended for the largest currents, the current really circulates first round one ring and then round the other.
Sodium salicylate circulates in the blood unchanged, decomposition occurring in the kidney, and probably in tissues suffering from the Diplococcus rheumaticus of Poynton and Paine.
But this competition among inventors, whatever the incentive, has not been without benefit, because to-day, by means of very simple improvements in details, such as the addition of circulators and increased area of connexions, what may be taken to be the standard type of multiple-effect evaporator (that is to say, vertical vacuum pans fitted with vertical heating tubes, through which passes the liquor to be treated, and outside of which the steam or vapour circulates) evaporates nearly double the quantity of water per square foot of heating surface per hour which was evaporated by apparatus in use so recently as 1885 - and this without any increase in the steam pressure.
In its original form, this consists of a long tube surrounded by an outer tube so arranged that cold water circulates in the annular space between the two.
Of other common types of condenser, we may notice the "spiral" or "worm" type, which consists of a glass, copper or tin worm enclosed in a vessel in which water circulates; and the ball condenser, which consists of two concentric spheres, the vapour passing through the inner sphere and water circulating in the space between this and the outer (in another form the vapour circulates in a shell, on the outside and inside of which water circulates).
Three types of columns are employed: (I) the elongation is simply a straight or bulb tube; (2) the column, properly termed a "dephlegmator," is so constructed that the vapours have to traverse a column of previously condensed vapour; (3) the column is encircled by a jacket through which a liquid circulates at the same temperature as the boiling-point of the most volatile component.
The Weir, the condensing water circulates upwards through the tubes; in others, e.g.
The Quiggins, the water circulates around the tubes.
In 1839 St Petersburg became the headquarters of an agency of the British and Foreign Bible Society, which enjoys special facilities in Russia, and now annually circulates about 600,000 copies of the Scriptures, in fifty different languages, within the Russian empire.
Let us now examine the organs which lie beneath the mantle-skirt of Anodonta, and are bathed by the current of water which circulates through it.
Thus in parts of California, where high temperatures are liable to prevail during the vintage, the system - first employed in Algeria - of cooling the must during fermentation to the proper temperature by means of a series of pipes in which iced water circulates is now largely employed.
Quinine hydrochloride circulates in the alkaline blood without precipitation, probably owing to the presence of carbonic acid in the blood.
With liquid machines of the compression and absorption system, the rooms are either cooled by means of cold pipes or surfaces placed in them, or by a circulation of air cooled in an apparatus separated from the rooms. The cold pipes may be direct-expansion pipes in which the liquid evaporates, or they may be pipes or walls through which circulates an uncongealable brine previously cooled to the desired temperature.
Small doses of any of them dilate the blood vessels from an action on the vaso-motor centre in the medulla oblongata, as a result of which the heart beats more rapidly and the blood circulates more freely; but larger doses have a general depressing effect upon the circulatory system.
It can be shown that if a current i circulates in a small plane circuit of area S, the magnetic action of the circuit for distant points is equivalent to that of a short magnet whose axis is perpendicular to the plane of the circuit and whose moment is iS, the direction of the magnetization being related to that of the circulating current as the thrust of a right-handed screw to its rotation.
The walls, therefore, are now made thin, and are thoroughly cooled by water, which circulates through pipes or boxes bedded in them.
Their place has been taken by foreign gold, principally the English sovereign, which circulates at a value of 974 piastres.
On the Arab coast the rupee is legal tender, and is almost exclusively used for commercial transactions, but the Maria Teresa dollar circulates freely, and is preferred by the inhabitants of the interior of Arabia.
The steam rising from the latter is passed into a similar pan, in which it circulates round another set of pipes, but as it could not bring the liquid in the latter to boil under ordinary conditions, the second pan is connected with a vacuum-pump so that the boiling-point of the liquid in this pan is lowered.
The displacer (E),which takes its motion through a rod (I) from a rocking lever (F) connected by a short link to the crank-pin, is itself the regenerator, its construction being such that the air passes up and down through it as in one of the original Stirling forms. The cooler is a water vessel (G) through which water circulates from a tank (H).
The drug circulates in the blood in the form of an albuminate and is slowly excreted by the kidneys.
