Temperature coefficients of cochlear potentials

American Journal of Physiology-Legacy Content, 1960
Guinea pigs were subjected to hypothermia; cochlear potentials and cochlear temperatures were measured. The cochlear microphonic and endocochlear potential decreased during cooling. The mean Q10 of the cochlear microphonic potential was 1.58. Q10's of the endocochlear potential were with one exception, appreciably lower, ranging from 1.14 to 1.26. The

The temperature coefficient of capacitance

Journal of Physics D: Applied Physics, 1968
The temperature coefficient of capacitance (TCC) of most insulators is dominated by five components. The theoretical analysis of these components is outlined and it is shown that, for given ranges of permittivity, the analysis can be greatly simplified. This simplified treatment is shown to apply to widely different types of compound. Since TCC depends

TEMPERATURE COEFFICIENTS IN BIOLOGY

Biological Reviews, 1930
Summary.(a) The problem of temperature coefficients in biology was initiated by chemists and has suffered from the beginning from this circumstance. Attempts to apply chemical temperature‐velocity formulae (the Q10 rule and the Van't Hoff‐Arrhenius law) to biological processes failed, because none of the temperature constants used in chemistry (Q10, μ)

Dependence of Strain Coefficient on Temperature and Dependence of Temperature Coefficient on Strain for Distributed Strain and Temperature Discrimination

26th International Conference on Optical Fiber Sensors, 2018
The strain coefficient dependence on temperature and the temperature coefficient dependence on strain have been proven for the first time. With these coefficients from SMF-28e and AOC fiber we have demonstrated that a strain accuracy of 6µe and temperature accuracy of 0.3°C with 50cm spatial resolution can be achieved using the distributed Brillouin ...

Temperature Coefficient of Vulcanization

Industrial & Engineering Chemistry, 1939
Abstract One hundred years ago rubber was the only available substance having the property of long-range elasticity which makes rubber so useful to man. The invention of vulcanization tremendously increased the usefulness of rubber, since it decreased the plastic flow at elevated temperatures and increased the resistance to hardening at low ...

Temperature Coefficients and Acclimatization

Nature, 1940
CERTAIN biologists (especially Crozier1 and his school) have formulated theories on the effects of changing temperatures on protoplasm. The numerical value of the temperature coefficient (= Q10 = of a biological reaction is believed to afford a clue to the nature of the controlling physical or chemical changes.

The Temperature Coefficient of the Refractive Index of Water*

Journal of the Optical Society of America, 1948
A Jamin interferometer was used to measure the thermal coefficient of the refractive index of water for sodium light (λ=5893A) from −5°C to +25°C. From this was calculated the index-temperature curve over the same range. The results agree with those found by the Bureau of Standards for water within the experimental error, which is between 1×10−6 and 2 ...

On the Temperature Coefficient of Diffusion

Proceedings of the Physical Society of London, 1911
The Paper describes further experiments carried out by the Author with an improved form of the apparatus previously described ("Proc." Ph. Soc., XXI., p. 374), by means of which the value of the coefficient of diffusion of salts through water can be found at various temperatures.

Zero-temperature Hall coefficient of an insulator

Physical Review Letters, 1992
We prove that for noninteracting electrons at zero temperature, an insulator exhibits finite Hall resistivity in the dc limit. More generally, we present simple macroscopic arguments that this behavior is generic for all insulators. We therefore conclude that the zero-temperature Hall coefficient is not a measure of the number of mobile carriers.
