Recently, the stability calculation of functionally graded (FG) plate has attracted many scientists, especially when considering FG with cracks. In this work, is made from a new generation composite material consisting two components, ceramic and metal, law continuous exponential distribution. The placed on Winkler - Pasternak elastic foundation background parameters. Then, we used third-order ...

In this study, a realistic model for dynamic instability of embedded single-walled nanotubes (SWCNTs) conveying pulsating fluid is presented considering the viscoelastic property of the nanotubes using Kelvin–Voigt model. SWCNTs are placed in longitudinal magnetic fields and modeled by sinusoidal shear deformation beam theory (SSDBT) as well as modified couple stress theory. The effect of slip ...

1 Receptors have been implicated in the modulation of opioid analgesia. In the current study, we examined the role of 1 systems in the periaqueductal gray (PAG), the rostroventral medulla (RVM), and the locus coeruleus (LC) of the rat, regions previously shown to be sensitive to morphine. Morphine was a potent analgesic in all three regions. Coadministration of the 1 agonist ( )-pentazocine dim...

The elastic foundation beam theory has been widely used in civil engineering, including railway, tunnel, and building foundations. With the development of fabricated structures, more beams need to be prestressed. In order explore frame with anchor-cable slope reinforcement project, this article, prestress is applied both ends beam. Then, according calculation method internal force deformation u...
