The unsymmetrical form of the meridional pencil - formerly the only one considered - is coma in the narrower sense only; other errors of coma have been treated by A.
(2) The condition for freedom from coma in the third order is also of importance for telescope objectives; it is known as " Fraunhofer's condition."
These anastigmatic lenses, which are manufactured up to X 40, are chromatically and spherically corrected, and for a middle diaphragm the errors of lateral pencils, distortion, astigmatism and coma are eliminated.
I read that when people wake up from a coma, it's always gradual.
(4) After eliminating the aberration on the axis, coma and astigmatism, the relation for the flatness of the field in the third order is expressed by the " Petzval equation," I 1 = o, where is the radius of a refracting surface, n and n' the refractive indices of the neighbouring media, and / the sign of summation for all refracting surfaces.
In large doses it has a depressant action on the nervous system, leading even to coma and total abolition of reflex action.
Death may be preceded by coma, but consciousness is often maintained to the end.
So, once a person came out of the coma, could they go back into it?
Amongst these, the most important is fever with increased protein metabolism, attended with disturbances of the circulatory and respiratory systems. Nervous symptoms, somnolence, coma, spasms, convulsions and paralysis are of common occurrence.
After he came out of the coma, he underwent a year or so of therapy.
The euphoria of his awakening from the coma passed as other symptoms persisted.
The doctor said they could find no reason for him to stay in a coma, except the possibility of brain damage from lack of oxygen or blood loss.
"And so when you woke up from the coma, you couldn't speak," she said.
The docs put you in a coma for over a week in order to transplant half your organs.
Intense drowsiness yields to sleep and coma which ends in death from failure of the respiration.
The name Coma Berenices, applied to a constellation, commemorates this incident.
There may be bleeding from the nose, cutaneous congestion, deafness, blindness, coma or delirium, and even death from cardiac failure.
In acute mania it acts like hyoscyamine in producing sleep. In large doses stramonium is a narcotic poison producing the wellmarked stages of exaltation of function, diminution of functional activity, and later loss of function, sinking into coma and paralysis.
He diverged from Ptolemy when he placed the asterisms Coma Berenices and Antinous upon the level of formal constellations, Ptolemy having 1 The historical development of star-catalogues in general, regarded as statistics of the co-ordinates, &c., of stars, is given in the historical section of the article 'ASTRONOMY.
The doctor said there was no reason for him to remain in a coma and he might wake up any day.
The aberrations of the third order are: (1) aberration of the axis point; (2) aberration of points whose distance from the Aberra- axis is very small, less than of the third order - the tions of deviation from the sine condition and coma here fall together in one class; (3) astigmatism; (4) curvature of the field; (5) distortion.
No one said it, but internet research indicated that a coma which lasted more than two weeks might become permanent.
Hopefully it was the remnants of the coma and would wear off.
If the patient survives the coma, recovery is complete and as a rule rapid, without secondary symptoms.
It forms a valuable treatment in diabetic coma and eclampsia, acting by diluting the toxins in the blood.
Hence it is of the utmost importance to avoid the use of salts of this metal whenever it is necessary - as in diabetic coma - to increase the alkalinity of the blood rapidly.
In such cases the acute collapse occurs in company with both superficial and deep anaesthesia of the limbs, and is soon followed by coma terminating in death.
Could the fact that Howie's brain waves are somehow different after his lengthy coma and all the operations he endured be effected by what you were doing?
