Mobile ad hoc network is nothing but the temporary network which is having the collection of mobile nodes. Routing and broadcasting are major operations of MANET network. The major operation in ad hoc mobile network is the broadcasting which sometime results to storm problem of the broadcast if the forwarding mechanism is not properly designated. Thus the challenges in the MANET are to reduce the broadcasting redundancy and under high transmission error rate provides high delivery ratio. Hence in our proposed research, we are introducing and investigating the new mechanism of broadcasting called Dual Covered Broadcast. This method takes the broadcast redundancy advantage order to improve packet delivery ratio especially under environments where transmission error rate higher. According to proposed approach, among the senders 1-hop neighbors, forwarding nodes which are selected are only retransmit the broadcasting message. There are two ways for selection of forwarding nodes and either of one is used depending on the network conditions. The source node provides forwarding node retransmission as acknowledgement of reception of packet. If the source node not getting the retransmissions of its forwarding nodes, source node resend the packets until the maximum threshold will reach. For the simulation of this project we used the Microsoft .Net framework and our simulation results shows that proposed method performing well under the high transmission error rate. From the simulated results we claim that investigated approach for the broadcasting is more efficient as compared to the existing approaches.
Background: Varicose veins are common in Iraq. Increasing incidence is associated with available jobs of bodyguards, barbers and computer workers.
Objectives: To highlight the frequency, presentation, methods of accurate diagnosis and surgical procedures which are commonly used by Vascular Surgeons in Medical City Teaching Complex, Al-Shaheed Ghazi Al-Hariri Subspecialties hospital and to compare this study with other international studies.
Patients and methods: This is a retrospective study of hundred patients with varicose veins, who were admitted and surgically treated at Al-Shaheed Ghazi Al-Hariri subspecialties hospital during one year period (1st of July 2010

This study aims to show the markers of the Arabic noun(genitive, nun nation articles,
vocative, definite article and predication). These markers distinguish the noun from other
parts of sentence. It alsoaims at showing why these markers are peculiar to nouns.
Objectives: To document electromyographic changes in thyrotoxic patients, and to categorize the type of myopathic process in thyrotoxicosis.
Design: This case control study was designed to show the electromyographic changes in thyrotoxic patients and to compare these findings with that of normal aged matched controls to
show the significance of these changes in thyrotoxic patients. Student’s test was applied on the results and P value was extracted.
Subjects: Subjects in this study were chosen according to certain criteria depending mainly on their blood level of thyroid hormone (T3, and T4) and TSH. All of them are thyrotoxic patients, their ages range between 15 to 45 years. They were 25 patients (15

Free – living or limax amoebae are small free-living protozoans which exist in fresh water and soil environment. These amoebae were found infective to man causing a fatal disease affecting the central nervous system. Fowler and Carter were the first to report four fatal human cases of acute pyogenic meningitis caused by free-living amoebae1. The genera Naegleria and Acanthamoeba are incriminated in such infections2. Swimming in contaminated water has been frequently postulated as the way of infection through the intranasal mucosa. Since
that time more than one hundred cases of primary amoebic meningoencephalitis were reported from different parts of the world. On&
Background:
The aim of this article is to introduce a new definition of domination number in graphs called hn-domination number denoted by . This paper presents some properties which show the concepts of connected and independent hn-domination. Furthermore, some bounds of these parameters are determined, specifically, the impact on hn-domination parameter is studied thoroughly in this paper when a graph is modified by deleting or adding a vertex or deleting an edge.
