atrogenic atrial septal defect (IASD), post Catheter ablation during electrophysiological study simply can be assess with Echocardiography nowadays ablation consider the main line in the managements of patients with various type of arrhythmia. This study aims to de-termine the outcomes of Iatrogenic Atrial Septal Defect (IASD) six months post radiofrequency ablation (RF) procedure of left atrial arrhythmia using non-invasive Transtho-racic Echocardiography (TTE) parameters (LVEF, E/e` and ASD size) with sheath size as predictors of atrial septal defect closure. Patients and methods: A prospective study was con-ducted in Iraqi Centre for Heart Diseases included 47 patients post Electrophysiology procedure and ablation of left atrial SVT were selected after non complicated tran-septal puncture using two size of sheath in three type of arrythmia and follow up done simply with Transthoracic echocardiography (TTE) was used to evaluate the atrial septal defect (ASD) (from May 2019-May 2020) in Iraqi centre for heart diseases. Results: After Electrophysiology study, results of this study were analysed and collected according to duration of procedure, sheath size and number that used in sep-tostomy, size of IASD and Echocardiographic parameters. The mean age of the patients (36.28±10.34 years), males were 23 (48.9%) while females were 24 (51.1%), without structural heart diseases and good LV function with mean EF (64.68± 5.23%). Iatrogenic atrial septal defects (IAS-Ds)were detected by TTE in all patients with range from (2-5) mm with mean of (3.47±0.92), performed by Trans-septal puncture (TSP), either with single 8 French sheath in 24 (51.06%) patients or single 12 French sheath in 17 (36.17%) patients while 6 (12.77%) patients the defect was performed by double transseptal sheath. spontane-ous closure occur in 35(74%) patients within first three months with clear significant association between size of ASD that related to the sheath size and duration of procedure (P<0.0001). We notice that some Echocardiographic parameters were also associated with IASD without any clinical complications and/ or deterioration. Conclusions: post catheter ablation number and size of sheath and duration of ablation consider as a predictor to closure of residual atrial septal defect post atrial sep-tostomy and can simply assess with non-invasive Trans-thoracic Echocardiography parameters such (Atrial septal defect size and body surface area) during initial six months follow up. © 2021, Venezuelan Society of Pharmacology and Clinical and Therapeutic Pharmacology.

Commercial graphite (CGT) powder was used as an adsorbent surface for cationic dye, Janus green (JG), from aqueous solutions. This study aims to highlight the practical significance of using inexpensive CGT as an efficient adsorbent for the removal of JG dye from industrial wastewater. CGT was characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, and X-ray diffraction. The adsorption process was investigated by examining parameters like the weight of the adsorbent, contact time, and temperature. Pseudo-second-order kinetic (PSO), pseudo-first-order, and intraparticle diffusion were used for analyzing the kinetic data. JG dye's adsorption kinetics fit the PSO kinetic model well (R2= 0.999).

The aim of the current study is to explore the related relationship between the Islamic blazon and its visual publicity message. The sample is contained Five of Islamic blazon in the Mamelukes period which is between 1250 to 1517. The methodology is descriptive-analytical, and the result is that there is a clear relation between the Islamic blazon with its visual publicity message. This study's recommendation is to go towards analyzing the meanings of the cultural legacies of the Islamic civilization, and researching the implicit meanings accompanying these features leads to a deeper understand
... Show MoreIn this study, we focused on the random coefficient estimation of the general regression and Swamy models of panel data. By using this type of data, the data give a better chance of obtaining a better method and better indicators. Entropy's methods have been used to estimate random coefficients for the general regression and Swamy of the panel data which were presented in two ways: the first represents the maximum dual Entropy and the second is general maximum Entropy in which a comparison between them have been done by using simulation to choose the optimal methods.
The results have been compared by using mean squares error and mean absolute percentage error to different cases in term of correlation valu

This research aims to design a multi-objective mathematical model to assess the project quality based on three criteria: time, cost and performance. This model has been applied in one of the major projects formations of the Saad Public Company which enables to completion the project on time at an additional cost that would be within the estimated budget with a satisfactory level of the performance which match with consumer requirements. The problem of research is to ensure that the project is completed with the required quality Is subject to constraints, such as time, cost and performance, so this requires prioritizing multiple goals. The project

The study also looked into their concepts, forms, dimensions and types and the role of e-Government on fraud reduction, corruption in administration and finance and its impact on the government performance. From the result, it is revealed that there is need for electronic government for implementation in order to curb the rate of fraud and administrative and financial corruption and improve the quality of service provision for better performance
The A.C conductivity of three samples of lanthanide oxide : zinc oxide (La2O3)1-x(ZnO)x pellets with different zinc oxide content which were sintered 1273 K temperatures were studied using LRC meters in the frequency range of 50–106 Hz at temperature of 30 °C. The a.c conductivity, was analyzed depending of the universal power law proposed by Jonsher,. The slope of the relation between logarithm of a.c conductivity and angular frequency represent the s value were in the range (0.44-0.77) which found to increase by increasing of zinc oxide content which coincided with the small po
