Long and equipped with electric light, stationary and travelling hydraulic cranes, machinery for meat freezing, and large sheds for storing corn and wool.
We shall then show that on certain limitations two trains of disturbance may be superposed so that stationary waves may be formed, and thence we shall deduce the modes of vibration as with pipes.
A few experimental results are set forth in Table XX., from which it will be seen that with a relatively low rate of combustion, a rate which denotes very light service, namely lb of coal per square foot of grate per hour, the efficiency of the boiler is %, which is as good a result as can be obtained with the best class of stationary boiler or marine boiler even when using economizers.
The success of procryptic coloration depends, however, very largely upon stillness, and the instinct to keep stationary without moving a limb is a marked characteristic of all spiders unless engaged in hunting or fleeing from imminent danger.
The returns thus obtained show that from the year 1723 until 1846 the population remained almost stationary, the figure in the former year being 26,065,422, and that in the latter year 26,907,625.
Above and below these movable coils, which form as it were the two scalepans of a balance, are fixed other stationary coils, and the connexions of all these six coils (shown in fig.
, (7) and when q is stationary, the acceleration is normal to the surface H = constant, and the stream line is a geodesic.
Snakes are the most stationary of all vertebrates; as long as a locality affords them food and shelter they have no inducement to change it.
In view of this opinion and of the exhaustion of the shallower collieries we look forward to a time, not far distant, when the rate of increase of output will be slower, to be followed by a period of stationary output, and then a gradual decline."
19 a - towards the face, upon which the miner lies and controls the direction of the blow by a pair of handles at the back of the machine, which is kept stationary by wedging the wheels against a stop on the platform.
The amplitude of the phase is 1ï¿½1 magnitude; and the absence of any stationary interval at minimum proves the eclipse to be partial, not annular.
In order to justify the use of stationary waves we must show that two such trains can move in opposite directions over the same ground without modifying each other so long as the displacement in either is small.
The stationary wave method regards the vibration in the pipe as due to a series of waves travelling to the end and being there reflected back down the pipe.
The stationary wave system adjusts itself so that its motion agrees with that of the sounder, which is therefore not exactly at a node.
& 'm =21rnapU, for in the stationary wave system the pressure change and the amplitude are both double those in either train, so that the same relation holds.
Population was practically stationary for centuries owing to pestilences and the large proportion of deaths among infants.
The Lyrids also vary in the position of their radiant, but the Orionids form a stationary position from about the 9th to the 24th of October.
Whilst the use of alcohol for power purposes, mainly in connexion with stationary and agricultural engines, was common in Germany before the war, its employment in Europe and also in the United States for motor engines has not made much headway, nor was it apparent in 1921 that any active steps were being taken outside the British Empire to develop it for the purpose on any considerable scale.
The re-export trade is stationary and extremely small.
As a preliminary to the investigation of the modes of vibration of certain sources of sound we shall consider the formation of " stationary waves."
28 are represented the stationary wave systems of the first four modes, and any of the succeeding ones are easily drawn.
The played bowl must itself run into the ditch without touching either of the stationary bowls.
29 are represented the stationary wave systems of the first four modes.
Since 1880, while income from the salt and lotto monopolies hai remained almost stationary, and that from land tax and octroi har - diminished, revenue derived from all other sources has notabl)
The white population is not only far larger but more cosmopolitan, less stationary and more dependent on a single industry; it has few links with the past, and both city and citizens bear the marks of youth.
Michell has discussed also the hollow vortex stationary inside a polygon (Phil.
Moreover, the stationary habit of plants, and the almost total absence of locomotion, makes it impossible for them to seek their food.
