Movements of forehead, eye, nose, or mouth, may succeed each other or be superimposed one on the other without any preconceived order, or the tic may consist in the synchronous activity of two or more muscles.
Synchronous involvement of the two sternomastoids will flex the head and approximate the chin almost to the sternum, but more commonly there is only a slight forward inclination of the head exactly similar to a gesture of assent.
One of us has had occasion to observe an excellent case in point in a young man afflicted with spasm of the orbicularis and zygomatics on the right side, in whom synchronous displacement of the uvula occurred with each twitch.
The patient with "convulsive" tic is conscious of it in the sense that he is well aware of its existence, yet how can the gesture be a conscious one if it is synchronous with mental preoccupation?
In physical exercises the surest results are achieved by the synchronous contractions of symmetrical muscles, whereas education is much more arduous should this lesson from experience be ignored.
Thus the patient has come to realise that she need but give her attention to the involuntary movements for them to cease, and there has been a synchronous advance in her mental activity and power of concentration.
There was synchronous spasm in the masseter muscles, resulting in elevation of the inferior maxilla.
Speaking generally, it may be said that downward movements of the arms are less good than upward ones, and that their synchronous and symmetrical action is accomplished with greater ease than is the operation of one only.
By this means, as well as by synchronous drawing exercises, he soon became so deft that he learned to conserve almost complete immobility during the performance, to his great satisfaction.
This increased action of the capillaries of the skin along with the increased actions of the stomach and heart is perhaps to be esteemed a synchronous increase of action, rather than a sympathy between those organs.
On the other, how account for a comparatively synchronous commencement of bronze civilization when one at least of the metals needed for the alloy would have been naturally difficult of access, if not unknown to many races?
From the similarity of types of weapons and implements of the period found throughout Europe a relatively synchronous commencement has been inferred for the Bronze Age in Europe, fixed by most authorities at between 2000 B.
Copper would thus have been but seldom used unalloyed; and the relatively synchronous appearance of bronze in Europe, and the scanty "finds" of copper implements, are explained.
For some purposes synchronous motors are not desirable, as for driving shafts in small workshops having no other power available for starting, and in cases where frequent starting, or a strong torque at starting is necessary.
Synchronous motors can be made to operate not only as motors but as synchronouscondensers to improve the power factor of the circuit.
The design of synchronous motors proceeds on the same lines as that of alternators, and the question of voltage regulation in the latter becomes a question of power factor regulation in the former.
The maximum torque is several times full load torque and occurs at synchronous speed.
By some observers the perfect trot is described as an absolutely synchronousmovement of the diagonal feet.
When these synchronousmovements and the successive attitudes they occasion are understood, we at once see the simplicity of animal locomotion, in all its various types and alternations.
The rack differs from the trot in the nearly synchronous action of the laterals instead of the diagonals.
For all history must be essentially universal; not in the sense of comprising all the synchronous events of the past time, but through the universality of the principles employed.
This construction assists in bringing the machine up tosynchronous speed as an induction motor, ordinarily checks any tendency toward hunting and does not in any way affect the operation of the machine as an alternator.
Stationary field of Fort Wayne multiphase revolving armature alternator; view showing brass girds on pole pieces for synchronous motor operation.
The object of this winding is to check any tendency toward hunting when the alternator is to be run as a synchronous motor, either for rotary condenser or power service.
These alternators may be used as synchronous motors and for this duty are fitted with amortisseur winding in the pole faces which does not interfere with their use as alternators.
The distinction consists in the fact that in the former the pain and soreness are below the line of respiratory sounds, although synchronous with them.
The great moment in the history of the world with which this celebration of his fame was synchronous could not fail to give the incident a brilliancy unparalleled in the history of music.
Upon the Gaboon the wet seasons are synchronous with the vertical suns at the vernal and autumnal equinoxes.
It measures some forty miles from north to south by half that depth, and its position causes the rains, which are synchronous with those of the Gaboon, to be much more copious and continuous.
This is what is generally called the "Synchronous History," the principal remains of which were discovered and published by H.
The passage from the Synchronous History, republished by Winckler, contains the termination of the mutilated name of a Babylonian king.
The Synchronous History erroneously places the events of the reign of Rammân-nirâri in that of Belnirârî.
Only synchronous with this ruling principle was the idea of national unity.
Yet synchronous with this the man of ideas and ideals that he kept to himself however; that he divulged to no one.
Among other historical documents of primary importance, a tablet generally known as "the Synchronous History" must be placed in the first rank.
In England the round-heads appear to be synchronous with the metal age, as shown by the contents of the barrows, and, as on the continental mainland, the two types gradually blended.
The laws of number are common to synchronous and successive phenomena.
As the dates when the different tribes became known vary, it follows as a matter of course that the periods represented by the colors in one portion of the map are not synchronous with those in other portions.
The rhythmic beating of the heart, synchronous with respiration and the circulation of the blood, are sufficient illustrations.
There has been woven into its organism a distinct and synchronous correspondence with that of the mother.
They are functionallysynchronous in all movements.
On the other hand, the individual intelligence of the child, a distinct and separate unity, is in vital, spiritual, and synchronous relation to that of the mother that enfolds it.
It is not known if these movements were synchronouswith those of Europe, but it is established that, as in Europe, the first invasion of glaciers was also the more widespread.
After excision of the adrenals the blood remained normal for from four to six hours, when the H-ion concentration increased rather suddenly, the increase being synchronous with the incidence of the phenomena which immediately preceded death.
If the oxygen in the inhaled mixture be increased, a decrease in acidity is again synchronous with lighter anesthesia and a decrease in the respiratory rate.
This rapid acidulation is synchronous with almost instantaneous unconsciousness and increased respiration.
