SOME TEMPERATURE CHARACTERISTICS IN MAN [PDF]

open access: yesJournal of General Physiology, 1935
The value of µ = 29,400 has been found for the human heart beat over the temperature range of approximately 4.7°C. This value is different from that of 24,000 calories which has been obtained for the effect of temperature on judgments of short durations.

Characteristic temperatures of folding of a small peptide [PDF]

open access: yesProceedings of the National Academy of Sciences, 1997
We perform a generalized-ensemble simulation of a small peptide taking the interactions among all atoms into account. From this simulation we obtain thermodynamic quantities over a wide range of temperatures. In particular, we show that the folding of a small peptide is a multistage process associated with two characteristic temperatures ...

THE TEMPERATURE CHARACTERISTIC OF RESPIRATION OF AZOTOBACTER [PDF]

open access: yesJournal of General Physiology, 1932
The temperature characteristic of respiration of Azotobacter vinelandii possesses a constant value of 19,330 ± 165 over the temperature range 20–30°C. This value is independent of pH, oxygen tension, age of culture, and other factors within the limits studied.

A phenomenological model of galaxy clusters [PDF]

open access: yes, 2007
We present a simple model to describe the dark matter density, the gas density, and the gas temperature profiles of galaxy clusters. Analytical expressions for these quantities are given in terms of only five free parameters with a clear physical meaning:

Temporal behavior of two-wave-mixing in photorefractive InP:Fe versus temperature [PDF]

open access: yes, 2006
The temporal response of two-wave-mixing in photorefractive InP:Fe under a dc electric field at different temperatures has been studied. In particular, the temperature dependence of the characteristic time constant has been studied both theoretically and

Growth Temperatures and Temperature Characteristics of Aeromonas

open access: yesApplied Microbiology, 1971
Six of the 13 Aeromonas hydrophila , 1 of 10 A. shigelloides , and none of 10 A. salmonicida were found to be psychrophiles. All of the rest of the strains were mesophiles.

Entanglement in a Quantum Mixed-Spin Chain [PDF]

open access: yes, 2006
The entanglement in a general mixed spin chain with arbitrary spin $S$ and 1/2 is investigated in the thermodynamical limit. The entanglement is witnessed by the magnetic susceptibility which decides a characteristic temperature for an entangled thermal ...
