We report a piezoelectric effect in cholesteric liquid crystalline elastomer gels. When we apply a shear stress to a cholesteric elastomer gel in the direction perpendicular to its helical axis, a polarization can be induced in the direction perpendicular to both the stress and the helix. This experimental observation agrees with the theory proposed by Pelcovits and Meyer ͓J.

The lateral line system allows a fish to respond to changes in its surroundings by detecting flow stimuli. The velocity, acceleration, pressure gradient, and shear stress of water at the surface of a fish may all serve as stimuli that yield cues about environmental change. All of these stimuli are governed by hydrodynamics. Therefore, an application of hydrodynamic principles offers insight int...

It is well established that stress is related to changes in eating patterns. Some individuals are more likely to increase their overall food intake under conditions of stress, whereas others are more likely to consume less food when stressed. Attachment style has been linked to disordered eating and eating disorders; however, comparisons of eating behaviors under attachment versus other types o...

conclusions de-stress training program significantly decreased the stress of mothers with show paced children, and the training effect was persistent. results data presented a significant difference between the control and experiment groups. also, results did not show a significant difference between the post-test and follow up. it means that the effect of training was persistent. background ha...

a pot experiment in randomized complete blocks design (rcbd) with six treatments in four replications was conducted to study the effect of water stress on morphological characteristics and essential oil content of improved basil (ocimum basilicum c.v. keshkeni luvelou). the irrigation treatments for induction of water stress were: a: (125 ml/ 12 h), b: (250 ml/ 24 h), c: (250 ml/ 48 h), d: (500...

objective: the determinants of satisfaction of life (swl) are poorly described among iranian employed ‎nurses. this study aimed to assess the effect of various factors including age, gender, marital ‎status, depression, anxiety and stress on swl among iranian nurses.‎ method: employed nurses in three teaching hospitals were invited to participate in this study. ninety-four ‎nurses (65 women and...

this study was conducted to evaluate the genetically effective traits that related to drought tolernace using 14 bread wheat lines and cultivars where in previous experiment clusterd into two resistant and susceptible groups under non-stress and stress conditions using randomized complete block design replicated three times. the combined analysis based on north carolina desing ii for studied tr...

to study the effect of drought stress during using organic and chemical fertilizers on morphological, agronomic traits and the essential oil of coriander, a field experiment was conducted as split plot based on randomized complete block design in three replications at agricultural research station, college of agriculture, university of torbat heydarieh, iran during growing season of 2010-2011. ...
