Forgotten Index and Forgotten Coindex of Graphs
...Show More Authors

F index is a connected graph, sum of the cubes of the vertex degrees. The forgotten topological index has been designed to be employed in the examination of drug molecular structures, which is extremely useful for pharmaceutical and medical experts in understanding the biological activities. Among all the topological indices, the forgotten index is based on degree connectivity on bonds. This paper characterized the forgotten index of union of graphs, join graphs, limits on trees and its complements, and accuracy is measured. Co-index values are analyzed for the various molecular structure of chemical compounds

Further Results on Graceful Antimagic Graphs
...Show More Authors

     Graceful labeling of a graph  with q edges is assigned the labels for its vertices by some integers from the set such that no two vertices received the same label, where each edge is assigned the absolute value of the difference between the labels of its end vertices and the resulting edge labeling running from 1 to  inclusive. An edge labeling of a graph G is called vertex anntimagic, if all vertex weights are pairwise distinct, where the vertex weight of a vertex under an edge labeling is the sum of the label of all edges incident with that vertex.  In this paper, we address the problem of finding graceful antimagic labelin for split of the star graph ,  graph,  graph, jellyfish graph , Dragon graph , ki

Background: Colostomy minimizes the risk of leakage at expense of requiring a second operation. In Iraq, published on colostomy closure in penetrating abdominal wall injuries is scarce.

Objective: to Study the prognosis of colostomy closure in post-conflict patients in Iraq.

Objective: to Study the prognosis of colostomy closure in post-conflict patients in Iraq.

Method: This is a retrospective study of 52 patients subjected to colostomy closure, recruited for the period 2008 to 2009 from Al-Yarmouk Teaching Hospital and Children Central Teaching Hospital. Demographic data and information about colostomy (type, methods of preparation … etc.) were studied.

Results: Trauma was noticed in 57.7% patients. Transverse colon was the commone

Topological Structure of Generalized Rough Graphs
...Show More Authors

The main purpose of this paper, is to introduce a topological space , which is induced by reflexive graph and tolerance graph , such that  may be infinite. Furthermore, we offered some properties of  such as connectedness, compactness, Lindelöf and separate properties. We also study the concept of approximation spaces and get the sufficient and necessary condition that topological space is approximation spaces.

More on Result Involution Graphs
...Show More Authors

     The result involution graph of a finite group , denoted by  is an undirected simple graph whose vertex set is the whole group  and two distinct vertices are adjacent if their product is an involution element. In this paper, result involution graphs for all Mathieu groups and connectivity in the graph are studied. The diameter, radius and girth of this graph are also studied. Furthermore, several other graph properties are obtained.

Resultant Graphs of Block Designs
...Show More Authors

In this paper we have made different regular graphs by using block designs. In one of our applicable methods, first we have changed symmetric block designs into new block designs by using a method called a union method. Then we have made various regular graphs from each of them. For symmetric block designs with  (which is named finite projective geometry), this method leads to infinite class of regular graphs. With some examples we will show that these graphs can be strongly regular or semi-strongly regular. We have also propounded this conjecture that if two semi-symmetric block designs are non-isomorphic, then the resultant block graphs of them are non-isomorphic, too.
