Abstract In this paper,using a structural decomposition analysis (SDA) and the latest available input-output tables we investigate the sources of labor productivity growth in Norway, South Korea and Iran. Then, the contribution of each source in the growth of labor productivity is discussed. The results show that among six factors, value added coefficient is the most influencing factoracross al...

Bacillus spp. are Gram-positive spore-forming bacteria used commercially as probiotics in the larviculture of fish. Bacillus spp. can act positively on cultured organisms by enhancing their survival and growth, stimulating their digestive and immune systems, and improving water quality. In this present study, grass carp larvae were fed on Artemia urmiana, Artemia fransiscana and Artemia parthen...

Internal radiation was investigated using the finite volume method for the heat exchanger method (HEM) growth of oxide crystals. Special attention was devoted to the temperature and thermal stress distributions in the bottom region of the grown crystal at the end of the solidification process. The numerical results show that internal radiation strongly strengthens heat transport through the cry...

We give a convergence criterion for stationary iterative schemes based on subproper splittings for solving rectangular systems and show that, for special splittings, convergence and quotient convergence are equivalent. We also analyze the convergence of multisplitting algorithms for the solution of rectangular systems when the coefficient matrices have special properties and the linear systems ...

A polynomial is expansive if all of its roots lie outside the unit circle. We define some special determinants involving coefficients a real and formulate necessary sufficient conditions for expansivity using these determinants. show how can be turned into an algorithm, which, integer polynomials, avoids exponential coefficient growth. also examine question close to circle are integers. give se...

Although during recent years in the field of special education there has been much debate regarding inclusion and people’s beliefs around disability, it is suggested that what has been lacking in many of the discussions is any coherent guiding philosophy that helps direct research in this area. The paper proposes that critical realism, developed by philosopher Roy Bhaskar, may provide such a fr...
