Artificial Selection to a Nonlethal Cold Stress in Trogoderma variabile Shows Associations With Chronic Cold Stress and Body Size

Cold stress and the cold pressor test.

Temperature and other environmental stressors are known to affect blood pressure and heart rate. In this activity, students perform the cold pressor test, demonstrating increased blood pressure during a 1- to 2-min immersion of one hand in ice water. The cold pressor test is used clinically to evaluate autonomic and left ventricular function. This activity is easily adapted to an inquiry format...

Stress Analysis and Energy Estimation in Cold-Roll Forming Process

In this article, stress analysis and energy estimation during cold-roll forming of symmetrical channel sections have been discussed. Geometry of sheet strip is pre-estimated by a shape function. Then longitudinal, transversal and shear strains have been calculated. Using both the Levy-Mises and the Prandtl Reuss equations, and also considering the Bauschinger effect, stress distributions have b...

Cold stress and cholinergic supersensitivity.

To the Editor: In the rat (adult male Sprague-Dawley) chronic forced swim stress (Dilsaver et al. 1986) and chronic inescapable footshock (Dilsaver and Alessi 1987) induce marked supersensitivity to the hypothermic effects of the muscarinic cholinergic agonist oxotremorine. These observations are consistent with a report that immobilization of 10 min duration activates the septohippocampal musc...
