Research ArticleOpen accessIn the abstractNew Analysis for The FGM Thick Cylinders Under Combined Pressure and Temperature LoadingK. Abrinia, H. Naee, F. Sadeghi, F. DjavanroodiAn analytical solution for computing the radial and circumferential stresses in a FGM thick cylindrical vessel under the influence of internal pressure and temperature is presented in this paper. It has been assumed that the modulus of elasticity and thermal coefficient of expansion were varying through thickness of the FGM material according to a power law relationship. Nevertheless the value … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,123 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Heat Treatment Parameters on Distribution and Volume Fraction of Mg2Si in the Structural Al 6063 AlloyG. Al-MarahlehAluminum Profiles -Production by extrusion from aluminum billets require a certain degree of homogeneity because of the segregated second phase particles, which are available in the as cast structure of the billets. Worldwide practice suggests a long homogenizing process at elevated temperatures in order to achieve such condition. This study showed that profiles extruded from homogenized and unhomogenized billets did … …American Journal of Applied Sciences, Vol. 3, Issue 5 · 8 May 2006 · 7,783 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Murine Charged Multivesicular Body Protein 2A, CHMP2A Interacts with the 5' and 3' Terminal Regions of Dengue Virus Complementary Minus-strand RNASuchita Chaudhry, Sathyamangalam Swaminathan, Navin KhannaDengue (DEN) viruses, of which there are four distinct serotypes (DEN-1, -2, -3 and –4), belong to the Flaviviridae family. Their ‘plus’ sense RNA genomes contain Non-Translated Regions (NTRs) at their 5’ and 3’ ends. Replication of viral genomic RNA, which takes place in close association with host cell membranes, involves the initial synthesis of the complementary minus sense RNA … …American Journal of Infectious Diseases, Vol. 2, Issue 1 · 31 Mar 2006 · 7,314 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFourier Series With Spectral and Wave Number DecompositionJung-Hua Chou, Raylin WuIn this study, the generic nature of Fourier series is pointed out and the requirement of dimensional homogeneity for physical systems is emphasized. By suitable application of non-dimensional variables, both time versus frequency and spatial versus wave number decomposition of Fourier series are included properly to put the physics involved into the right physical meanings. Furthermore, the high frequency noise … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,249 accessesView PDF Cite
