The role of multi-detector CT (MDCT) in patients presented with non-traumatic acute abdominal conditions
...Show More Authors

Background: Acute abdominal pain classically refers to pain within the abdomen that has been present for less than 7 days from the time of presentation. The use of CT scan in the evaluation of acute abdominal pain has increased to a large extent due to high accuracy of CT in the diagnosis of specific diseases like appendicitis and diverticulitis, especially with the use of multidetector CT scanners. It has been shown that the use of intravenous contrast media increases the diagnostic accuracy of CT scan examination, with a positive predictive value of 95% in the cases of acute appendicitis. The accuracy of CT scan imaging in patients with acute abdominal pain was not affected by the lack of entral contrast material.
Objectives: To evaluate the real usefulness of multi-detector CT( MDCT) in non-traumatic acute abdomen, to determine the cause of acute abdomen in those with uncertain pathological diagnosis.
Patients and methods: This prospective study had been conducted at Al-Sader medical city from the first of January to the first of September 2015. Our study includes all patients presented to the emergency department with non-traumatic acute abdominal conditions with uncertain underlying cause inspite of detailed history and physical examination with negative or non-conclusive U/S, plain abdominal XR finding and the surgeon failed to identify the exact underlying pathology. This study included (80) patients, (44 male and 36 female) . Non-enhanced CT scan was done first for all patients which was sufficient to reach the diagnosis in (22) patients, contrast material were not used because blood urea was elevated in (6) patients . In (8) patients, CT angiography protocol was performed for patients with suspected mesenteric vessels pathology. In the remaining (44) patients, intravenous contrast was given manually via a wide bore cannula ( gauge 18) and post contrast scan done in the portal phase (delay time 45-50 second).
Results: In this study, which was performed on (80) patients with undiagnosed nontraumatic acute abdominal conditions. We found that acute pancreatitis (20 patients)(25%) was the most common cause of undiagnosed acute abdominal pain, followed by intestinal obstruction (12 patients)(15%).While acute cholecystitis (8 patients)(10%) , portal or mesenteric vein thrombosis (8 patients ) (10%) , perforated viscus ,(6 patients)(7.5%), mesenteric arterial thrombosis (4 patients) (5%) ,left gastric artery aneurysm (2patient))(2.5%) , acute appendicitis(2 patient ) (2.5%)diverticulitis (2patient) (2.5%) and ectopic pregnancy (2patient) (2.5%). In (14 patients) (17.5%), no specific pathology could be detected.
Conclusion: The role of multi-detector CT (MDCT) has an important role in the management undiagnosed acute abdominal conditions in the emergency department. Acute pancreatitis is one of the main cause of undiagnosed acute abdominal conditions.

Fuzzy Soc-Semi-Prime Sub-Modules
...Show More Authors

     In this paper, we study a new concept of fuzzy sub-module, called  fuzzy socle semi-prime sub-module that is a generalization the concept of semi-prime fuzzy sub-module and fuzzy of approximately semi-prime sub-module in the ordinary sense.  This leads us to introduce level property which studies the relation between the ordinary and fuzzy sense of approximately semi-prime sub-module. Also, some of its characteristics and notions such as the intersection, image and external direct sum of fuzzy socle semi-prime sub-modules are introduced. Furthermore, the relation between the fuzzy socle semi-prime sub-module and other types of fuzzy sub-module presented.

Network Performance Analysis Based on Network Simulator NS-2.
...Show More Authors

     NS-2 is a tool to simulate networks and events that occur per packet sequentially based on time and are widely used in the research field. NS-2 comes with NAM (Network Animator) that produces a visual representation it also supports several simulation protocols. The network can be tested end-to-end. This test includes data transmission, delay, jitter, packet-loss ratio and throughput. The Performance Analysis simulates a virtual network and tests for transport layer protocols at the same time with variable data and analyzes simulation results based on the network simulator NS-2.

Objective: The aims of research to identify sample of websites of Arabian medical periodicals and exam applying to
standards for publishing on the internet.
Methodology: A survey method is applied about nine medical periodicals websites and data are collected through
forms include five international standards to assessing websites.
Results: of data collected, the following findings are obtained:
1. Through examining website addresses, unsuitability was found in using Universal Resources Locater, because six of
periodicals use com. in URL. While, all of them not relevance commercial but scientific aim.
2. To measure Credibility Standard by adopting numbers values, the results found, four of periodicals obtained (level

Content Based Image Retrieval (CBIR) by Statistical Methods
...Show More Authors

            An image retrieval system is a computer system for browsing, looking and recovering pictures from a huge database of advanced pictures. The objective of Content-Based Image Retrieval (CBIR) methods is essentially to extract, from large (image) databases, a specified number of images similar in visual and semantic content to a so-called query image. The researchers were developing a new mechanism to retrieval systems which is mainly based on two procedures. The first procedure relies on extract the statistical feature of both original, traditional image by using the histogram and statistical characteristics (mean, standard deviation). The second procedure relies on the T-

A COMPARISON BETWEEN SOME HIERARCHICAL CLUSTERING TECHNIQUES
...Show More Authors

In this paper, some commonly used hierarchical cluster techniques have been compared. A comparison was made between the agglomerative hierarchical clustering technique and the k-means technique, which includes the k-mean technique, the variant K-means technique, and the bisecting K-means, although the hierarchical cluster technique is considered to be one of the best clustering methods. It has a limited usage due to the time complexity. The results, which are calculated based on the analysis of the characteristics of the cluster algorithms and the nature of the data, showed that the bisecting K-means technique is the best compared to the rest of the other methods used.

Towards Solving Fractional Order Delay Variational Problems Using Euler Polynomial Operational Matrices
...Show More Authors

     In this paper, we introduce an approximate method for solving fractional order delay variational problems using fractional Euler polynomials operational matrices. For this purpose, the operational matrices of fractional integrals and derivatives are designed for Euler polynomials. Furthermore, the delay term in the considered functional is also decomposed in terms of the operational matrix of the fractional Euler polynomials. It is applied and substituted together with the other matrices of the fractional integral and derivative into the suggested functional. The main equations are then reduced to a system of algebraic equations. Therefore, the desired solution to the original variational problem is obtained by solving the resul

      Field of translation is sampled with many types of translation, such as the literary, scientific, medical, etc. The translation of grammatical aspects has always been with difficulties.

Political translation is the focus here. There are many general problems faced by translators when translating political texts from Arabic into Spanish. The aim here is to clarify the definition of functions or terms within the text, and to arrive at the correct from of translation of such texts from Spanish into Arabic.  It is worth mentioning that the paper is of two parts: the first exemplifies what is meant by translation, the prerequisites of a translator, along with mentioning the methods followed&nbs

Direction Finding Using GHA Neural Networks
...Show More Authors

 This paper adapted the neural network for the estimating of the direction of arrival (DOA). It uses an unsupervised adaptive neural network with GHA algorithm to extract the principal components that in turn, are used by Capon method to estimate the DOA, where by the PCA neural network we take signal subspace only and use it in Capon (i.e. we will ignore the noise subspace, and take the signal subspace only).
