With the aid of techniques developed by Edmonds, Ringel, and Youngs, it is shown that the genus of the cartesian product of the complete bipartite graph K2m,2m with itself is l + 8m2(m — 1). Furthermore, let ßi" be the graph K„,s and recursively define the cartesian product ßi," = ß?L x x Klfl for nä2. The genus of ß(„" is shown to be 1 + 2" " 3s"(sn—4), for all n, and í even ; or for n > 1, an...

A set of vertices S resolves a graph G if every vertex is uniquely determined by its vector of distances to the vertices in S. The metric dimension of G is the minimum cardinality of a resolving set of G. Let {G1, G2, . . . , Gn} be a finite collection of graphs and each Gi has a fixed vertex v0i or a fixed edge e0i called a terminal vertex or edge, respectively. The vertex-amalgamation of G1, ...

OBJECTIVES The aim of this study was to determine the effect of epigallocatechin gallate (EGCG) on the shear bond strength of composite resin to bleached enamel. MATERIALS AND METHODS Ninety enamel surfaces of maxillary incisors were randomly divided into 9 groups as follows: G1: control (no bleaching); G2: bleaching; G3: bleaching and storage for seven days; G4 - 6: bleaching and application...

Given two genomic maps G1 and G2 each represented as a sequence of n gene markers, the maximal strip recovery (MSR) problem is to retain the maximum number of markers in both G1 and G2 such that the resultant subsequences, denoted as G ∗ 1 and G∗ 2 , can be partitioned into the same set of maximal substrings of length greater than or equal to two. Such substrings can occur in the reversal and n...

The canine golden retriever muscular dystrophy (GRMD) model is the best animal model for studying Duchenne muscular dystrophy in humans. Considering the importance of glucose metabolism in the muscles, the existence of metabolic and endocrine alterations in a wide range of muscular dystrophies, and the pre-existing relationship between blood insulin concentration and muscular atrophy, the prese...

the main aim of this study was to obtain the crimean-congo hemorrhagic fever virus (cchfv) glycoprotein, through either stable transgenic plants or using a transient expression system, and determine the yield, quality and finally the immunogenicity of the plant-made cchfv glycoprotein in a mouse model. we designed and synthesized a codon-optimized g1/g2 gene from the g1 and g2 parts of the cchf...

In the framework of Regge phenomenology, masses of the charmed states cq̄ (q = u, d, s) lying on the 13S1-like trajectories are estimated. The overall agreement between our estimated masses and the recent predictions given by modified quark models[hep-ph/0605019, hep-ph/0608011, hep-ph/0608139] is good. Masses of the observed charmed statesDs0(2317), DsJ (2860) and DsJ(2690)/DsJ(2700) can be rea...
