stress relieving is a common practice among manufacturing codes for reducing the magnitude ofresidual stresses in welded, quenched, and tempered steel structures and pressure vessels. the presentwork investigates the effect of stress relieving at 480, 560, 620, and 680°c on the microstructure andmechanical properties of 20 mm astm a517 gr. b steel plate weldments produced by shielded metal arcw...

introduction: it is known that acute and chronic stress induce hormonal and neuronal changes which affecting both pain threshold and nociceptive behaviours. orexin plays an important role in modulation of pain and stress. considering pain modulation during stress and the role of orexin in pain and stress, orexin might be involved in pain modulation during stress.we evaluated the involvement of ...

microdialysis was used to measure the effect of benzodiazepines (bdzs) on basal levels and on stress-induced increases of 5 -hydroxytryptamine (5 -ht), 5 - hydroxyind oleacetic acid (5 -hiaa) , noradrenaline (na), and dihydroxyphenylacetic acid (dop ac). the stressors used were a 5 min tail pinch or a 10 min period of restraint. a subcutaneous injection of 5 mg/kg diazepam decreased basal level...
