The mangrove sediment from the Mae Klong River (MK) and Khon Canal (KK) revealed microplastics contamination in Estuary environment. Microplastic analyses were analyzed by using ZnCl2 density separation H2O2 digestion process. average concentrations of microplastic was 580 1690 items kg-1 dry weight samples MK KK. contained more coarse grain than KK sediment. lower concentration mainly related ...

For a set of graphs F, let ex(n,F) and spex(n,F) denote the maximum number edges spectral radius an n-vertex F-free graph, respectively. Nikiforov (LAA, 2007) gave version Turán Theorem by showing that spex(n,Kk+1)=λ(Tk(n)), where Tk(n) is k-partite graph on n vertices. In same year, Feng, Yu Zhang (LAA) determined exact value spex(n,Ms+1), Ms+1 matching with s+1 edges. Recently, Alon Frankl (a...

1, the KK heuristic performs poorly as n increases. This is despite the fact that these problems have perfect partitions that can often be found with little search. 1 1e+10 1e+20-40-20 0 20 40 60 80 100 "n=6" "n=12" "n=18" "n=24" Figure 9.

Superoxide excess plays a central role in tissue damage that results from diabetes, but the mechanisms of superoxide overproduction in diabetic nephropathy (DN) are incompletely understood. In the present study, we investigated the enzyme superoxide dismutase (SOD), a major defender against superoxide, in the kidneys during the development of murine DN. We assessed SOD activity and the expressi...

We extend some recent results on sufficient conditions for Hamiltonian paths and cycles in G. Let G be a graph of order n and λ (G) be the spectral radius of its adjacency matrix. One of the main results of the paper is the following theorem: Let k 2, n k3 + k + 4, and let G be a graph of order n, with minimum degree δ (G) k. If λ (G) n k 1, then G has a Hamiltonian cycle, unless G = K1 _ (Kn k...

A structural description is given of the separable C algebras that are contractible in KK theory or E theory Subsequently it is shown that two separable C algebras A and B are KK equivalent if and only if there is a bundle of separable C algebras over which is piecewise trivial with no more than six points of non triviality such that the kernel of each ber map is KK contractible all ber maps ar...

We construct the effective action of the KK-monopole in a massive Type IIA background. We follow two approaches. First we construct a massive M-theory KK-monopole from which the IIA monopole is obtained by double dimensional reduction. This eleven dimensional monopole contains two isometries: one under translations of the TaubNUT coordinate and the other under massive transformations of the emb...
