Normal vibration frequencies of the vocal ligament.
The vocal ligament is the tension-bearing element in the vocal folds at high pitches. It has traditionally been treated as a vibrating string, with only length and longitudinal stress governing its normal mode frequencies. Results of this investigation show that, when bending stiffness and variable cross section are included, the lowest normal mode frequency can more than double, depending on t...
متن کاملThe Pathological Anatomy of Hydrazine
In a recent article in the Journal of Biological Chemistry 2 is reported a study of the influence of hydrazine upon the intermediary metabolism in the dog, by Professor F. P. Underhill and I. S. Kleiner, in which it is shown that although this poison produces extensive anatomical alterations in the liver of dogs, yet it causes little change in the partition of urinary nitrogen and sulphur, beyo...
متن کاملVibration perception in normal man and medical patients.
Interest in sensitivity to vibration as an aid to neurological diagnosis began in 1889 when Rumpf tested this function in a case of syringomyelia (Fox and Klemperer, 1942). Subsequent investigators found altered vibratory sensitivity in various disorders of the nervous system (e.g., Williamson, 1922). Reduced sensitivity, for example, has been reported in peripheral neuritis, diabetes mellitus,...
متن کاملCharge-vibration interaction effects in normal-superconductor quantum dots
We study the quantum transport and the nonequilibrium vibrational states of a quantum dot embedded between a normal-conducting and a superconducting lead with the charge on the quantum dot linearly coupled to a harmonic oscillator of frequency ω. To the leading order in the charge-vibration interaction, we calculate the current and the nonequilibrium phonon occupation by the Keldsyh Green’s fun...
متن کاملTonic vibration reflex in spasticity, Parkinson's disease, and normal subjects.
The tonic vibration reflex (TVR) has been studied in the quadriceps and triceps surae muscles of 34 spastic, 15 Parkinsonism, and 10 normal subjects. The TVR of spasticity develops rapidly, reaching a plateau level within 2-4 sec of the onset of vibration. The tonic contraction was often preceded by a phasic spike which appeared to be a vibration-induced equivalent of the tendon jerk. The initi...
