The nonlinear dynamic analysis of imperfect hemispherical shell under pressure was executed. finite element model hemisphere in the software NASTRAN built. wall form three-cornered and four-cornered net presented. Shape imperfection as a lower buckling (Buckling) perfect action static modelled. Value amplitude set proportionally to thickness. Two boundary conditions rigid hinged supports on nod...
In this study, the dynamic buckling of the embedded laminated nanocomposite plates is investigated. The plates are reinforced with the single-walled carbon nanotubes (SWCNTs), and the Mori-Tanaka model is applied to obtain the equivalent material properties of them. Based on the sinusoidal shear deformation theory (SSDT), the motion equations are derived using the energy method and Hamilton's p...
HE last few years have witnessed the accumulation of a considerable body experimental data dealing with the isolation of mitochondrial mutants in yeast conferring resistance to various inhibitors and with the results of two, three or four factor crosses using these mutants as genetic markers. All these results can be classified as belonging to two types of experimental approaches: one based ess...
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 ...
In the late 1980s, a group of researchers interested in the alkaline phosphatase of Escherichia coli discovered something odd. In their paper, the authors briefly described a strange genomic topology consisting of a series of 32 nucleotides of unique sequence, flanked by short invariable palindromic repeats on the 3' end of the phosphatase gene that they had been studying (Ishino et al., 1987)....
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
manganese in RT-PCR eliminates PCR artifacts resulting from DNase I digestion. BioTechniques 22:1128-1132. 3.Bolotin, A., S. Mauger, K. Malarme, S. Ehrlich, and A. Sorokin. 1999. Low-redundancy sequencing of the entire Lactococcus lactis IL1403 genome. Antonie Van Leeuwenhoek 76:27-76. 4.Buchman, G., D. Schuster, and A. Rashtchian. 1993. Selective RNA amplification: a novel method using dUMP-co...
