this study investigated the inhibitory effects of bacillus licheniformis on g1 and g2 aflatoxins in culture media and kilka fish meal. two concentrations of aflatoxins (8 and 12 ppb for g1 and g2) and (2 and 4 ml from aflatoxins standard per 50g of fish meal) were used in culture media and kilka fish meal respectively. the doses of bacillus were 3 and 4% for this experiment. changes of aflatoxi...

Abstract. Given two graphs G1, with vertices 1, 2, ..., n and edges e1, e2, ..., em, and G2, the edge corona G1 ⋄G2 of G1 and G2 is defined as the graph obtained by taking m copies of G2 and for each edge ek = ij of G, joining edges between the two end-vertices i, j of ek and each vertex of the k-copy of G2. In this paper, the adjacency spectrum and Laplacian spectrum of G1 ⋄ G2 are given in te...

Checkpoint response to DNA damage involves the activation of DNA repair and G2 lengthening subpathways. The roles of nibrin (NBS1) and the ATM/ATR kinases in the G2 DNA damage checkpoint, evoked by endogenous and radio-induced DNA damage, were analyzed in control, A-T and NBS lymphoblast cell lines. Short-term responses to G2 treatments were evaluated by recording changes in the yield of chromo...

Maize leaf blades differentiate dimorphic photosynthetic cell types, the bundle sheath and mesophyll, between which the reactions of C(4) photosynthesis are partitioned. Leaf-like organs of maize such as husk leaves, however, develop a C(3) pattern of differentiation whereby ribulose bisphosphate carboxylase (RuBPCase) accumulates in all photosynthetic cell types. The Golden2 (G2) gene has prev...

Given a system G = (G1,G2, . . . ,Gm) of m graphs on the same vertex set V , define the “joint independence number” α∩(G) as the maximal size of a set which is independent in all graphs Gi . Let also γ∪(G) be the “collective domination number” of the system, which is the minimal number of neighborhoods, each taken from any of the graphs Gi , whose union is V . König’s classical duality theorem ...

We compute the algebra of differential invariants unparametrized curves in homogeneous G2 flag varieties, namely G2/P. This gives a solution to equivalence problem for such curves. consider cases integral and generic relate problems all three choices parabolic subgroup P.

We find closed form formulas for the Kemeny’s constant and Kirchhoff index cluster G1{G2} of two highly symmetric graphs G1, G2, in terms parameters original graphs. also discuss some necessary conditions a graph to be symmetric.
