Let G be a graph with vertex set V (G) and edge set E(G), and let g and f be integer-valued functions defined on V (G) such that 0 ≤ g(x) < f(x) for all x ∈ V (G), and let H1 and H2 be two edge-disjoint subgraphs of G. We prove that G has a (g, f) -factor F such that E(H1) ⊆ E(F ) and E(H2) ∩ E(F ) = ∅ if G satisfies (1) g(x) + dH2(x) ≤ dG(x) and f(x) ≥ dH1(x) for all x ∈ V (G), and (2) (f(x)− ...
Studies of gene x environment (G x E) interaction in ADHD have previously focused on known risk genes for ADHD and environmentally mediated biological risk. Here we use G x E analysis in the context of a genome-wide association scan to identify novel genes whose effects on ADHD symptoms and comorbid conduct disorder are moderated by high maternal expressed emotion (EE). SNPs (600,000) were geno...
For assessment of genotype × environment (G × E) interaction effects and determination of the most sustainable genotypes 20 barely lines were analyzed in at eight different experimental field stations. The experiments were performed based on Randomized Complete Block Design (RCBD) with three replicates. Grain yield was obtained and the results of the combined analysis of variance revealed genot...
In 1970, Menegazzo [Gruppi nei quali ogni sottogruppo e intersezione di sottogruppi massimali, Atti Accad. Naz. Lincei Rend. Cl. Sci. Fis. Mat. Natur. 48 (1970), 559--562.] gave a complete description of the structure of soluble $IM$-groups, i.e., groups in which every subgroup can be obtained as intersection of maximal subgroups. A group $G$ is said to have the $FM$...
Definition: If (G, *) and (H, •) are groups, then a function f : G −→ H is a homomorphism if f (x * y) = f (x) • f (y) for all x, y ∈ G. Example: Let (G, *) be an arbitrary group and H = {e}, then the function f : G −→ H such that f (x) = e for any x ∈ G is a homomorphism. In fact, f (x * y) = e = e • e = f (x) • f (y).

Only finite simple graphs are considered in this paper. For the most part, our notation and terminology follows that of Bondy and Murty [4]. Let G = (V ,E) denote a graph with vertex set V = V(G) and edge set E = E(G). We will use the following notation and terminology for a typical graph G. Let V(G) = {v1,v2, . . . ,vn} and E(G) = {e1,e2, . . . ,em}. We use |S| to denote the cardinality of a s...
Background: Critical macromolecules of cells such as DNA are in exposure to damage of free radicals that induced from the interaction of ionizing radiation with biological systems. Selenium and vitamin-E are natural compounds that have been shown to be a direct free radical scavenger. The aim of this study was to investigate the radioprotective effect of selenium and vitamin-E separately and sy...
Bi-directional communication, which enhances the effectiveness of education through question-and-answer and/or discussion sessions, is important in asynchronous e-Learning systems. Assignments are also important for e-Learning programs to motivate students and track their learning. However, assigned reports in e-Learning programs are submitted online, and it is very easy for students to plagiar...
