the aim of this study was to produce some of data needed for completing the iranian feed composition tables. the analyzed data in this research was from eilam range plants. the information about the range plants was collected from laboratory of animal science research institute of iran and some data was obtained from the final reports of research projects. the metabolized energy of range plants...

The building sector accumulates approximately a third of the final energy consumption. Consequently, the improvement of the energy efficiency in buildings has become an essential instrument in the energy policies to ensure the energy supply in the mid to long term moreover is the most cost-effective strategy available for reducing carbon dioxide emissions This paper is studying the main objecti...

The problem of recovering the asymptotics of a short range perturbation of the Euclidean Laplacian on R n from xed energy scattering data is studied. It is shown that for n 3 that a magnetic potential is determined, modulo Gauge invariance, by its scattering matrix at a xed non-zero energy. This result also holds for a wide class of scattering manifolds.

let $a = (a_{i,j})_{1 leq i,j leq n}$ be an $n times n$ matrixwhere $n geq 2$. let $dt(a)$, its second immanant be the immanant corresponding to the partition $lambda_2 = 2,1^{n-2}$. let $g$ be a connected graph with blocks $b_1, b_2, ldots b_p$ and with$q$-exponential distance matrix $ed_g$. we given an explicitformula for $dt(ed_g)$ which shows that $dt(ed_g)$ is independent of the manner in ...

In this paper, we present a method for characterizing the evolution of time-varying complex networks by adopting a thermodynamic representation of network structure computed from a polynomial (or algebraic) characterization of graph structure. Commencing from a representation of graph structure based on a characteristic polynomial computed from the normalized Laplacian matrix, we show how the p...
