The purpose of this paper is to draw attention to an innovative use of literature in social science research where the literature may not only be seen as a secondary source of data (Strauss & Corbin 1990) but may also serve as the basis for theory building (Lewis & Grimes 1999; Saunders et. al. 1999). This will be exemplified by attempting to construct a theory of ‘IS business value’ from the l...

CO recombination kinetics has been investigated in the type II truncated hemoglobin from Thermobifida fusca (Tf-trHb) over more than 10 time decades (from 1 ps to ∼100 ms) by combining femtosecond transient absorption, nanosecond laser flash photolysis and optoacoustic spectroscopy. Photolysis is followed by a rapid geminate recombination with a time constant of ∼2 ns representing almost 60% of...

in the present study, the onset of double diffusive reaction-convection in a uid layer with viscous fluid, heated and salted from below subject to chemical equilibrium on the boundaries, has been investigated. linear and nonlinear stability analysis have been performed. for linear analysis normal mode technique is used and for nonlinear analysis minimal representation of truncated fourier serie...

in this paper, thermo-elastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient, internal pressure and external pressure is presented. given the existence of shear stress in the conical shell due to thickness change along the axial direction, the governing equations are obtained based on first-order shear deformation theory (fsdt). these equations are so...

abstract: the present study deals with the buckling analysis of the laminated composite truncated conical sandwich shells with flexible core subjected to combined axial compressive load and external pressure. higher order governing equations of the motion are presented for conical composite sandwich shells, where they are derived from the hamilton principle. then, by the use of improved higher-...

autosomal dominant congenital cataract (adcc) is the most common form of inherited cataracts and accounts for one-third of congenital cataracts. heterozygous null mutations in the crystallin genes are the major cause of the adcc. this study aims to detect the mutational spectrum of four crystallin genes, cryba1/a3 , crybb1 , crybb2 and crygd in an iranian family. genomic dna was isolated from w...
