in this research, the buckling and bending behaviour of smart nanocomposite plate reinforced by single- walled carbon nanotubes (swcnts) under electro-magneto-mechanical loadings is studied. the extended mixture rule approach is used to determine the elastic properties of nanocomposite plate. equilibrium equations of smart nanocomposite plate are derived using the hamilton’s principle based on ...

objective: results obtained from literature reviews and human studies have shown the analgesic effects of clove plant in toothache. the present work was undertaken in order to investigate the possible analgesic effect of clove oil in mice. materials and methods: fifty mice were divided into 5 groups: 1) saline; 2) essential oil (ess) 2%, 3) ess 5%, 4) ess10% and 5) ess 20%. the hot plate test (...

in recent years, more attention is paid to stainless steel 316l as fracture plate and fixation in human's body. present studies are focused on surface and metallurgical properties of this material. biocompatibelity of this material and its superior mechanical properties has made it the most demanded biomaterial. in this research, four different implants are investigated in three stages. four co...

some small gabbro patches emplaced along the thrust fault with w-e trend in the vicinity of maien bolagh village at the ht/mp metapelites, a part of the central iran zone (near to sanandaj-sirjan zone). the coarse-grained dark gabbro samples consist of amphibole, clinopyroxene, plagioclase, minor quartz, titanite, and biotite. gabbros have high potassic calc-alkaline to shoshonitic affinity. th...

previous studies have shown that morphine administration could inhibit neural tube development in rat embryos and produce behavioral defects in human and animals. in the present study, the effects of maternal morphine consumption on embryonic neural plate development in wistar rats were investigated. methods: twenty-four female wistar rats (250-300 g) were crossed with males. after pregnancy, t...

background and purpose: active learning, combined with computer-assisted instruction, can enhance medical students’ performance and learning. this article is an attempt to introduce a new web-based approach to information technology instruction for medical students. methods: eight topics were selected to be instructed in web-based workshops. phpbb forum was used for web-based collaborative lear...

The broad application of steel and steel-concrete bridges has caused significant vibration noise problems. Although the channel composite girder is a commonly used bridge type, transmission performance structural optimization design (concrete deck, stiffeners, transverse connection components, etc.) from perspective control have not been well studied. In this paper, experimental numerical appro...

Welding-induced residual stress is known to reduce the ultimate compressive strength of moderately slender stiffened panels under longitudinal compression. This paper contributes a quantified measure this reduction and draws some qualitative observations linking significance influence collapse mode panel. A series nonlinear finite element analyses are completed which covers range plate slendern...
