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...
Controlling the microbiological quality of water is important for its uses. Microbiological requirements of drinking water ensure the absence of coliforms, but may indicate the potential presence of other potentially pathogenic microorganisms and viruses of fecal origin. A total of 36 water samples, representing the drinking water of the whole city of Aradan, Semnan, Iran, were randomly collect...
Knowledge of Nubia/Somalia relative motion since the Early Neogene is of particular importance in the Earth Sciences, because it (i) impacts on inferences on African dynamic topography; and (ii) allows us to link plate kinematics within the Indian realm with those within the Atlantic basin. The contemporary Nubia/Somalia motion is well known from geodetic observations. Precise estimates of the ...
It is considered to re-formulate quantum theory as it appears: A theory of continuous and causal time evolution, interrupted by discontinuous and stochastic jumps. Relying on a global reduction process, a hypothesis is introduced postulating spontaneous collapse of superpositions of states which describe spontaneous absorption or emission. The collapse probability determines a mean collapse tim...
The polymerase chain reaction (PCR) was used to isolated five Xenopus homeobox clones (X-dll1 to 5) that are related to the Drosophila Distal-less (Dll) gene and we propose a subdivision of the vertebrate distal-less gene family according to sequence similarities. cDNA clones were isolated for X-dll2, 3 and 4, and their expression was studied by RNase protection and in situ hybridization. X-dll...
Accurate and reliable methods for the quantitative measurement of the growth of pleuropneumonia-like organisms have never been developed. Studies on members of this group of organisms have advanced in recent years to the stage at which further developments will be impeded by the lack of such methods. Generally techniques employed for rapid quantitation of bacterial growth, such as turbidity, pa...
