These words he repeated to everyone without exception or variation, and with the same expression on his full, cheerful, clean-shaven face, the same firm pressure of the hand and the same quick, repeated bows.
De Phys., 1811), in which he enunciated the hypothesis known by his name (Avogadro's rule) that under the same conditions of temperature and pressure equal volumes of all gases contain the same number of smallest particles or molecules, whether those particles consist of single atoms or are composed of two or more atoms of the same or different kinds.
When the load is being drawn out, the engine pulls directly on the main rope, coiling it on to its own drum, while the tail drum runs loose paying out its rope, a slight brake pressure being used to prevent its running out too fast.
The reason of this is apparently that the negative pressure of the pleural, and partly of the peritoneal, cavity tends to aspirate a liquid relatively thicker, so to speak, than that effused where no such extraneous mechanism is at work (James).
Nitrite of amyl has the power of dilating the arteries; it has consequently been employed with much success in lowering the blood pressure and removing the pain in angina pectoris.
In this there is no compressing pump, and the main pressure of the working air is simply that of the atmosphere.
This drove the English king to put still further pressure on the enemy; in 1359 he led out from Calais the largest English army that had been seen during the war, devastated all northern France as far as Reims and the borders of Burgundy, and thencontinuing the campaign through the heart of the winterpresented himself before the gates of Paris and ravaged the Ile de France.
Thus, if a common glass-jar be struck so as to yield an audible sound, the existence of a motion of this kind may be felt by the finger lightly applied to the edge of the glass; and, on increasing the pressure so as to destroy this motion the sound forthwith ceases.
The regular tides are hardly perceptible, but, under the influence of barometric pressure and wind, the sea-level occasionally varies as much as ft.
The pressure on CD will therefore be doubled.
