Analysis of Steel Communication Towers in Iraq Under the Effect of Seismic Loading

The telecommunication industry launched in Iraq two decades ago through three mobile network operators which are holding national licenses; Korek Telecom, Zain Iraq and Asiacell. Since the launch date till now, more than twelve thousand of telecommunication towers have been installed in Iraq holding and transmitting the telecommunication traffic between the Iraqi regions. However, this huge number of towers have been analyzed under the effects of wind loading only without taking into considerations the seismic effects with noting that there are many tremors which have been receded in the recent past. Accordingly, a specific type of towers with different heights have been selected and analyzed under the effects of seismic loading using both equivalent static and response spectrum methods and then the results were compared with the gained results from the wind analysis. After obtaining and analyzing the results, it could be used as a milestone for such a study for the coming telecommunication towers or the existing towers with different topologies and categories

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely

ANDIN-MU: Development of Android-Based Descriptive Text Interactive Multimedia Materials in High School English Subjects

In learning there is a process of changing the behavior of a person who is initially unaware of something then becomes aware. In other words, there is a process of conveying knowledge between teachers and students or using learning materials. The purpose of this study was to develop interactive multimedia based on Android descriptive text material for Class X SMA Pasuruan English. This study uses the ADDIE model. In this development model there are five steps in the process, but in this study the researchers modified some of the steps used and adapted them to the environmental conditions affected by the Covid-19 pandemic climate. The steps taken are 4 out of 5 steps, namely (1) analysis (2) design (3) development and (4) evaluation. Collecting data in this study through interviews, documentation and questionnaires. The results showed that the media validation results scored 80%, while the content validation results obtained a score of 78%. The Likert scale used in the data calculation process shows that the developed interactive multimedia is very feasible to use in Pasuruan High Schoo

Experimental study on the performance of emulsions produced during ASP flooding

Abstract ASP (Alkaline/Surfactant/Polymer) flooding is one of the most promising techniques that has proven to have successful application in several laboratory and pilot tests. However, the formation of persistent and stable emulsions is one of the associated problems with ASP flooding. The present work investigated the effect of sodium carbonate alkaline, Alpha Olefin Sulfonate (AOS) surfactant, and GLP100 polymer on produced crude oil emulsion. The study was conducted by measuring the emulsion stability in terms of water separation and rag layer volume using a TurbiScan analyzer, the dispersed droplet size using cross-polarization microscopy, the interfacial tension using spinning drop tensiometer, and rheological properties using rheometer. The experimental results have shown that AOS presence increased the emulsion stability only when its concentration is above 100 ppm. Meanwhile, below 100 ppm, the presence of AOS promoted water separation and reduced the rag layer volume. In a less significant manner, a high concentration of sodium carbonate alkali increased the stability of the emulsion. The use of GLP100 Polymer has shown substantial ability in promoting water separation and reducing the rag layer volume to a minimal level. It is believed that the outcomes of this work will aid in developing a suitable destabilization process to enhance the oil–water separation and produced water treatment from ASP flooding in the oil production fields. Further investigations on AS, AP, SP as well as the ASP's combined effect on emulsion stability, droplet size, interfacial tension and rheological properties are highly recommended to support the decision-makers on the EOR implementations with chemical additives

The success rate of radiofrequency catheter ablation in Wolff-Parkinson-White-Syndrome patients: A systematic review and meta-analysis

Introduction: radiofrequency catheter ablation (RFA) is the first-line therapy for symptomatic Wolff Parkinson White (WPW) patients according to the American Heart Association. We conducted this study to assess the success rate, recurrence rate, and rate of complications associated with the utilization of radiofrequency catheter ablation for managing patients with WPW. Method: We searched PubMed, Cochrane library, Web of Science and Scopus databases using all identified keywords and index terms through 4 January 2022. We included all studies conducted on WPW patients who were treated with ablation. We conducted the analysis using Open Meta Analyst and MedCalc version 19.1. Results: Among 2268 unique articles identified, only 11 articles met our inclusion criteria. The pooled effect estimates showed high success rate (94.1%[95%CI:92.3–95.9], p < 0.001)), low recurrence rate (6.2% [95%CI:4.5–7.8, p < 0.001]) and low rate of complications (1%[95%CI:0.4–1.5, p < 0.001]). Conclusion: RFA showed a high success rate, low recurrence rate and low rate of complications in WPW patients
