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.

Facial Emotion Images Recognition Based On Binarized Genetic Algorithm-Random Forest
...Show More Authors

Most recognition system of human facial emotions are assessed solely on accuracy, even if other performance criteria are also thought to be important in the evaluation process such as sensitivity, precision, F-measure, and G-mean. Moreover, the most common problem that must be resolved in face emotion recognition systems is the feature extraction methods, which is comparable to traditional manual feature extraction methods. This traditional method is not able to extract features efficiently. In other words, there are redundant amount of features which are considered not significant, which affect the classification performance. In this work, a new system to recognize human facial emotions from images is proposed. The HOG (Histograms of Or

Spike neural network as a controller in SDN network
...Show More Authors

The paper proposes a methodology for predicting packet flow at the data plane in smart SDN based on the intelligent controller of spike neural networks(SNN). This methodology is applied to predict the subsequent step of the packet flow, consequently reducing the overcrowding that might happen. The centralized controller acts as a reactive controller for managing the clustering head process in the Software Defined Network data layer in the proposed model. The simulation results show the capability of Spike Neural Network controller in SDN control layer to improve the (QoS) in the whole network in terms of minimizing the packet loss ratio and increased the buffer utilization ratio.

Splitting the one-Dimensional Wave Equation, Part II: Additional Data are Given by an End Displacement Measurement
...Show More Authors

     In this research, an unknown space-dependent force function in the wave equation is studied. This is a natural continuation of [1] and chapter 2 of [2] and [3], where the finite difference method (FDM)/boundary element method (BEM), with the separation of variables method, were considered. Additional data are given by the one end displacement measurement. Moreover, it is a continuation of [3], with exchanging the boundary condition, where  are extra data, by the initial condition. This is an ill-posed inverse force problem for linear hyperbolic equation. Therefore, in order to stabilize the solution, a zeroth-order Tikhonov regularization method is provided. To assess the accuracy, the minimum error between

Multicomponent Inverse Lomax Stress-Strength Reliability
...Show More Authors

In this article we derive two reliability mathematical expressions of two kinds of s-out of -k stress-strength model systems; and . Both stress and strength are assumed to have an Inverse Lomax distribution with unknown shape parameters and a common known scale parameter. The increase and decrease in the real values of the two reliabilities are studied according to the increase and decrease in the distribution parameters. Two estimation methods are used to estimate the distribution parameters and the reliabilities, which are Maximum Likelihood and Regression. A comparison is made between the estimators based on a simulation study by the mean squared error criteria, which revealed that the maximum likelihood estimator works the best.

Phenol removal by electro-Fenton process using a 3D electrode with iron foam as particles and carbon fibre modified with graphene
...Show More Authors

The 3D electro-Fenton technique is, due to its high efficiency, one of the technologies suggested to eliminate organic pollutants in wastewater. The type of particle electrode used in the 3D electro-Fenton process is one of the most crucial variables because of its effect on the formation of reactive species and the source of iron ions. The electrolytic cell in the current study consisted of graphite as an anode, carbon fiber (CF) modified with graphene as a cathode, and iron foam particles as a third electrode. A response surface methodology (RSM) approach was used to optimize the 3D electro-Fenton process. The RSM results revealed that the quadratic model has a high R2 of 99.05 %. At 4 g L-1 iron foam particles, time of 5 h, and
