Temperature-dependent effects of ephedrine in the cold

Physiology & Behavior, 1996
This experiment examined the effects of intraperitoneal ephedrine (5-25 mg/kg) on operant thermoregulatory behavior of rats in the cold (-8 degrees C), and of 10 mg/kg on metabolic rate at a thermoneutral (22 degrees C) ambient temperature (Ta) and in the cold (5 degrees C). Posttest colonic temperature (Tc) decreased dose-dependently in the behavioral

Dietary self-selection at cold temperatures

Physiology & Behavior, 1971
Abstract Animals housed in the cold (2°C) were given the opportunity to select the components of their diets from protein and carbohydrae fractions. Housing in the cold was accompanied by depressed growth, which was not affected by giving the animals the opportunity to select their diets. Animals in the cold increased total caloric intake relative to

Effects of Cold Temperature on the Skin

2016
The response of skin to the application of surface cooling is manifested primarily as a local vasoconstriction and reduced blood flow. Major functions of skin blood flow (SBF) are to sustain the metabolic process of the skin cells and to facilitate heat transfer between the body core and the environment via the cutaneous circulation. One consequence of

Cold Sintering Process: A Novel Technique for Low‐Temperature Ceramic Processing of Ferroelectrics

, 2016
Research on sintering of dense ceramic materials has been very active in the past decades and still keeps gaining in popularity. Although a number of new techniques have been developed, the sintering process is still performed at high temperatures.

Prediction of skin temperature of men in the cold

Journal of Applied Physiology, 1961
Skin temperatures of seminude men were measured during 2-hr exposures to various combinations of air temperature (90–25 F) and wind velocities (< 1, 5, 10 mph). The data were used to derive an expression for the estimation of mean weighted skin temperature as a function of duration of exposure (up to 180 min), air temperature (90 to -20 F), and ...

PLANT COLD ACCLIMATION: Freezing Tolerance Genes and Regulatory Mechanisms.

Annual Review of Plant Physiology and Plant Molecular Biology, 1999
Many plants increase in freezing tolerance upon exposure to low nonfreezing temperatures, a phenomenon known as cold acclimation. In this review, recent advances in determining the nature and function of genes with roles in freezing tolerance and the ...

Entropy, Coldness and Absolute Temperature

1971
The main objective of thermodynamics is the determination of the fields of density ρ(xk, t) velocity υi(xk, t) empirical temperature ϑ(xk, t).

Effects of cold temperature, moisture and freeze-thaw cycles on the mechanical properties of unidirectional glass fiber-epoxy composites

, 2010
´The durability of composite materials used for wind turbines blades exposed to a northern climate presents uncertainties as their behavior for very cold temperature applications is not completely understood.

Chaos in the cold

Nature, 2014
A marriage between theory and experiment has shown that ultracold erbium atoms trapped with laser light and subjected to a magnetic field undergo collisions that are characterized by quantum chaos. See Letter p.475 The ability to tune the interactions between atoms or molecules cooled to ultracold ...
