Transatrial approach for total tetralogy of Fallot TOF correction: analysis of 24 cases.
...Show More Authors

Background: Tetralogy of Fallot TOF is the most common cause of congenital cyanotic heart disease. It is the most common congenital lesion that is likely to result in survival to adulthood and encountered in adult after repair. Tetralogy of Fallot comprises around 7.5 % of all congenital heart diseases in Iraq.
Objective: The aim of this study is to analyse the transatrial strategy for total correction of tetralogy of Fallot TOF.
Methods: Cross-sectional study was done during the period between 2012-2014 for twenty-four patients that admitted to Ibn Al-Bitar hospital in Baghdad with amenable TOF pathology for transatrial repair.
Results: Twenty-four patients, 16 were males and 8 were females. Ages ranged from 2-31 years. There was no early or late postoperative mortality in this review for follow-up period ranged from 6 – 24 months. The early and late postoperative echocardiography data in regard to pulmonary and tricuspid regurgitation and right ventricle RV function were delineated. Normal pulmonary valve (62.5%, 58.3%), mild pulmonary regurgitation (29.2%, 37.5%), moderate pulmonary regurgitation (8.3%, 4.2%). Normal tricuspid valve (75%, 70.8%), mild tricuspid regurgitation (20.8%, 20.8%), moderate tricuspid regurgitation (4.2%, 8.3%) respectively. No severe pulmonary or tricuspid regurgitation was reported. Postoperative RV function was normal in (87.5%, 83.3%), mild RV dysfunction in (8.3%, 12.5%), moderate RV dysfunction in (4.2%, 4.2%) respectively. No severe RV dysfunction was reported. The mean RVOT pressure gradient was 36.8 mmHg. This gradient decreased on follow-up echocardiography, mean 24.5 mmHg. P values were less than 0.05%.
Conclusion: The transatrial approach is a feasible technique for total repair of TOF in adequate pulmonary annulus size with satisfactory late postoperative echocardiography performance.

الخلفية:ان رباعية فالوت هي اكثر اسباب مرض ازرقاق الدم الولادي شيوعآ. وهو اكثر تشوهات القلب الخلقية التي تستمر في الحياة الى البلوغ، وتصادف عند البالغين بعد عمليات التصليح. ويشكل تشوه رباعية فالوت حوالي ٧.٥٪ من امراض القلب الخلقية في العراق.  

الهدف:ان الهدف من هذه الدراسة هو اجراء تحليل لطريقة عبر الاذين في عملية التصليح الكامل لرباعية فالوت.

الطرائق. هي دراسة مستعرضة تمت للفترة من ٢٠١٢ ولغاية ٢٠١٤. تم دراسة ٢٤ طفل ادخلوا في مستشفى ابن البيطار في بغداد، كان لديهم تشوه يسمح بالتداخل عبر الاذين.

النتائج٢٤ حالة، ١٨ ذكور و ٨ اناث. الاعمار تتراوح من ٢ ـ٣١ سنة. لم تسجل حالة موت بدائية او متقدمة في الدراسة الحالية ولمدة متابعة ٦ الى ٢٤ شهرا. معدل وقت دوران ماكنة القلب الصناعية كان ١٢٧ دقيقة. ومعدل غلق الشريان الابهر كان ١٠٣ دقيقة. ان مشاهدات فحص الامواج الصائتة القلبية مبكرا و متأخرا بعد العملية كان كما يلي، صمام رئوي طبيعي ٦٢.٥٪ و ٥٨.٣٪ ، تهدل الصمام الرئوي البسيط ٢٩.٢٪ و ٣٧.٥٪، تهدل الصمام الرئوي المعتدل ٨.٣٪ و٤.٢٪. صمام ثلاثي طبيعي ٧٥٪ و ٧٠.٨٪، تهدل الصمام الثلاثي البسيط ٢٠.٨٪ و ٢٠.٨٪، تهدل الصمام الثلاثي المعتدل ٤.٢٪ و ٨.٣٪. لاتوجد حالة تهدل صمام رئوي او ثلاثي شديد. كانت فعالية البطين الايمن الطبيعية ٨٧.٥٪ و ٨٣.٣٪، بسيطة الاعتلال ٨.٣٪ و ١٢.٥٪ معتدلة الاعتلال٤.٢٪ و ٤.٢٪، ولم تسجل شديدة الاعتلال. ان معدل نسب فرق الضغط عبر منفذ البطين الايمن كان ٣٦.٨ ملم زئبق. ان هذا الفرق يتضائل مع امتداد الفترة الزمنية، معدل ٢٤.٥ ملم زئبق. قيم معامل p كانت اقل من  ٠.٠٥ ٪.

الاستنتاج: ان طريقة عبر الاذين هي الية ممكنة في الاصلاح الكامل لرباعية فالوت بوجود حجم حلقة رئوية كافي مع اداء مرضي لفحص الامواج الصائتة القلبية المتأخر.

Correction Factor for Methods of Installation of Piles Group in Sandy Iraqi Soils
...Show More Authors

Many problems are facing the installation of piles group in laboratory testing and the errors in results of load and settlement are measured experimentally may be happened due to select inadequate method of installation of piles group. There are three main methods of installation in-flight, pre-jacking and hammering methods. In order to find the correction factor between these methods the laboratory model tests were conducted on small-scale models. The parameters studied were the methods of installation (in-flight, pre-jacking and hammering method), the number of piles and in sandy soil in loose state. The results of experimental work show that the increase in the number of piles value led to increase in load carrying ca

Free Vibration Analysis for Dynamic Stiffness Degradation of Cracked Cantilever Plate
...Show More Authors

 

In the present work a dynamic analysis technique have been developed to investigate and characterize the quantity of elastic module degradation of cracked cantilever plates due to presence of a defect such as surface of internal crack under free vibration. A new generalized technique represents the first step in developing a health monitoring system, the effects of such defects on the modal frequencies has been the main key quantifying the elasticity modulii due to presence any type of un-visible defect. In this paper the finite element method has been used to determine the free vibration characteristics for cracked cantilever plate (internal flaws), this present work achieved by different position of crack. Stiffness re

A Comparative Analysis of the Zernike Moments for Single Object Retrieval
...Show More Authors

Zernike Moments has been popularly used in many shape-based image retrieval studies due to its powerful shape representation. However its strength and weaknesses have not been clearly highlighted in the previous studies. Thus, its powerful shape representation could not be fully utilized. In this paper, a method to fully capture the shape representation properties of Zernike Moments is implemented and tested on a single object for binary and grey level images. The proposed method works by determining the boundary of the shape object and then resizing the object shape to the boundary of the image. Three case studies were made. Case 1 is the Zernike Moments implementation on the original shape object image. In Case 2, the centroid of the s

Determine The Factors Affecting Product Quality Using FMEA Analysis: A Case Study in Al Zawraa State Company
...Show More Authors

 

The research aims to identify the factors that affect the quality of the product by using the Failure Mode and Effect Analysis (FMEA) tool and to suggest measures to reduce the deviations or defects in the production process. I used the case study approach to reach its goals, and the air filter product line was chosen in the air filters factory of Al-Zawraa General Company. The research sample was due to the emergence of many defects of different impact and the continuing demand for the product. I collected data and information from the factory records for two years (2018-2019) and used a scheme Pareto Fishbone Diagram as well as an FMEA tool to analyze data and generate results.

The Absence of the Applied Semiotic Approach in Analyzing the Media Phenomenon
...Show More Authors

the contemporary Arab scholars deal with semiotics as an approach that helps them understand the texts, its meaning, and its structural functionalism . that’s why every now and then we find some
studies and researches using semiotics as an approach in study and comparatives, some of them even used the semiotic approach in analyzing old and new texts, while others think that semiotic holds and important place in critical approaches .
even though some of them considers semiotic just a trend of fashion this really didn’t lessen the value of semiotic as a scientific and procedural approach in literary and media studies as well as in analyzing literary and journalistic texts. for this reason it is considered as an important approa

The bony pelvis has a major role in weight transmission to the lower limbs. The complexities of its geometric form, material properties, and loading conditions render it an open subject to biomechanical analysis.

 The present study deals with area measurement, and three-dimensional finite element analysis of the hip bone to investigate magnitudes, load direction, and stress distribution under physiological loading conditions.

 The surface areas of the auricular surface, lunate surface, and symphysis pubis were measured in (35) adult hip bones. A solid model was translated into ANSYS parametric design language to be analyzed by finite element analysis method under different loading conditions.
