Procedures for numerical analysis of circadian rhythms
TLDR
Various procedures used in the analysis of circadian rhythms at the populational, organismal, cellular and molecular levels are reviewed. Expand
The circadian rhythm of body temperature
This article reviews the literature on the circadian rhythm of body temperature. It starts with a description of the typical pattern of oscillation under standard laboratory conditions, withExpand
The circadian rhythm of body temperature.
TLDR
This paper reviews the literature on the circadian rhythm of body temperature (CRT) and a section on the nervous control of the CRT is followed by summary and conclusions. Expand
Daily and estrous rhythmicity of body temperature in domestic cattle
TLDR
Cattle calves exhibit a very robust daily rhythm of body temperature, although this rhythm is absent at birth and develops during the first two months of life, which is more robust than that of any mammalian species previously studied. Expand

TLDR
The results of the various analyses allow the inference that, after high-frequency noise is filtered out, the value of the periodogram's Q(P) statistic reflects the extent of stationarity of the time series, and the "robustness" of a circadian rhythm can serve as an index of the station parity of the rhythm.

  • 15 September 2004
TLDR
The results indicate that at least in the species studied, the ability of rodents to modulate their exposure to the LD cycle does not have a major effect on photic entrainment. Expand
The Circadian Rhythm of Body Temperature of the Horse
TLDR
The various parameters of the body temperature rhythm of the horse are similar to those of several species of rodents previously studied, which confirms the endogenous nature of the rhythm. Expand
Circadian rhythms of body temperature and liver function in fed and food-deprived goats.
TLDR
Urea concentration in the blood exhibited daily rhythmicity only in the presence of a daily feeding regime and, therefore, was driven by ingestive and digestive processes and the liver cannot be identified as the site of the putative food-entrainable pacemaker. Expand
Computation of the effective body mass for metabolic studies of lean and obese rats.
  • R. Refinetti
  • Chemistry, Medicine
  • Metabolism: clinical and experimental
  • 1 August 1989
TLDR
The whole-animal metabolic rates of lean and obese rats cannot be directly compared because obese rats have much greater body mass than lean rats, and metabolic rate must be expressed per unit of effective body mass. Expand
Thermal chronobiology of domestic animals.
TLDR
The experimental results are consistent with the general principles of thermal chronobiology derived from laboratory studies and provide specific information about the peculiarities of livestock species. Expand
