Delayed Coronary Ostial Stenosis after Surgical Aortic Valve Replacement and Root Enlargement Treated with Beating Heart On-Pump CABG

引用

World Journal of Cardiovascular Diseases 2023年第10期13卷 657-663页

作者： Majed Tolah marwan Sadek Muhammed Tamim Yasser Elkady Cardiac Surgery Department Cardiac Center King Fahad Medical Military Complex Dhahran Saudi Arabia Cardiac Surgery Department Madinah Cardiac Center Madinah Saudi Arabia

Coronary ostial stenosis after surgical aortic valve replacement (SAVR) is a rare but potentially fatal complication. Surgeons must have a high level of vigilance regarding the presentation of acute myocardial ischemia, arrhythmia, and heart failure after AVR. According to most reports, this event can be time-dependent divided into two groups;early acute phase that mostly happens intraoperative during weaning of CPB or in early ICU stay, and late presentation usually appears 1 - 6 months post surgery. Here, we describe an unusual subacute presentation of right coronary ostial stenosis 12 days after SAVR, which was treated successfully with redo beating heart coronary artery bypass grafting (CABG).

Thermomechanical Testing of GGG 40 Spheroidal Graphite Cast Iron Alloy

引用

Materials Sciences and Applications 2017年第3期8卷 273-280页

作者： marwan Faisal Eman El-Shenawy Mohamed A. Taha Mechanical Design and Production Department Ain Shams University Cairo Egypt Department of Plastic Deformation Central Metallurgical R&D Institute Cairo Egypt

Spheroidal graphite cast iron GGG 40 was thermo-mechanically tested using thermo-mechanical simulator Gleeble-3500. Three deformation steps were successively applied on test-specimen at temperatures namely;900°C, 850°C and 750°C within the austenitic zone, at the same strain rate of 0.1 s-1. No cracks were observed, up to 50% deformation, after successive deformation steps. Stress-strain relationship obtained is correlated with previous work on SGCI with a different carbon equivalent. It was found that by decreasing the deformation temperature;for the same CE, young’s modulus, yield strength and strain hardening exponent increase. Microstructure of the deformed zone, for a specimen quenched after the final deformation step, reveals fine elongated ferrite and pearlite, as well as elongated graphite. While microstructure of the non-deformed zone subjected to the same treatment, includes coarser ferrite and pearlite with graphite spheres embedded in the matrix.

Journal of Water Resource and Protection 2012年第7期4卷 545-559页

作者： Hani Al-Amoush Elias Salameh marwan Al-Raggad Al al-Bayt University Mafraq Jordan Jordan University Amman Jordan

In this article the potential stoarativity of groundwater in the alluvial deposits along the King Abdullah Canal (KAC) in Deir Alla-Sulikhat area is studied. In this study geological, geoelectrical and Hydro-geochemical methods were used with the aim of storing some water of the Canal during water excess times in the underground to be extracted for use as drinking source for human during shortages in the Canal water and in emergency causes of Canal water pollution. The results show the existence of appropriate underground space in the alluvial deposits for water storage and that the water/ water and water/rock interactions are also be minimal and will not present and detriment to the different groundwater bodies. Implementing groundwater artificial recharge in the Jordan Valley area to create storage for King Abdullah Canal (KAC) water will enhance the drinking water supply during the dry season and it will also serve as a reserve for emergency causes, especially pollution accidents in King Abdullah Canal (KAC), such as those taking place almost every year.

Effect of Deformation Parameters on Microstructural Evolution of GGG 40 Spheroidal Graphite Cast Iron Alloy

引用

Materials Sciences and Applications 2019年第6期10卷 433-450页

作者： marwan Faisal Eman El-Shenawy Mohamed A. Taha Faculty of Engineering Ain-Shams University Cairo Egypt Central Metallurgical Research and Development Institute (CMRDI) Cairo Egypt

Studying the thermo-mechanical behavior of ductile iron is necessary to develop the rolling process for ductile iron sheet/strip production, thus, extending its application by replacing steel in several fields such as machine casing, constructional applications, etc. In order to predict the safe rolling conditions for producing sheets and strips, the thermo-mechanical behavior of a ductile iron alloy, with CE of 4.48, is studied by physical simulation of hot rolling process using Gleeble-3500 simulator. The test was conducted on specimens at a range of deformation temperatures from 800°C to 950°C while three different strain rates;namely 0.05, 0.1 and 0.5 s-1 were used. The results obtained, show minimum values of flow stresses at 850°C. By increasing the deformation temperature up to 900°C, the flow stresses increased to reach maximum values, beyond which the flow stress decreased again. A remarkable dynamic recrystallization is observed at the deformation temperatures of 850°C and 800°C with applied strain rates of 0.05 and 0.1 s-1. Gleeble test results are correlated with microstructure observations on samples quenched at their deformation temperatures, where the changes in structure and graphite morphology are reported. The deformation process at high temperatures namely 950°C and 900°C result in changing the graphite shape from a spheroidal-like to a saucer-like shape. However, by decreasing the deformation temperature to 850°C as well as 800°C, graphite with lamellar shape is observed. As a conclusion, ductile iron could be successfully deformed without cracking at the applied conditions.

Groundwater Pollution Due to Pesticides and Heavy Metals in North West Bank

引用

Journal of Environmental Protection 2011年第4期2卷 429-434页

作者： marwan Ghanem Subhi Samhan Erick Carlier Wasim Ali Bir Zeit University P.O.Box 14 Ramallah West Bank Polytech Lille Universite lille1 Lille France PWA Ramallah Wasim Ali KIT Karlsruhe Germany.

This study aims at determining the quantitative effect of pesticides including 2, 4-D dichlorphenoxy acetic acids, Paraquat, Atrazine (2-chloro-4-ethylamino-6-isopropylamino-striazine), and MCPP 2-(2-Methyl-4-chlorophenoxy) pro-panioic acid on groundwater quality due to agricultural in Jenin and Tulkarem, northern part of the West Bank. The concentrations of pesticides in Jenin was found to be higher than those in Tulkarem where the majority of the samples taken had concentration 10 μg/L. It is concluded that the contamination of the tested wells was due to pesticides and not wastewater disposal, since most of the samples were free from pathogenic indicators. Results revealed that using these wells for drinking purposes has a potentially high health risk. This is mainly due to the uncontrolled industrial and agricultural activity as well as the lack of monitoring. Concentrations of heavy metals including cadmium (Cd), lead (Pb), iron (Fe), zinc (Zn), chromium (Cr) and copper (Cu) were also quantitatively determined for the same period extending from April, 2004 to May, 2005. Concentrations of Pb and Cr in most of the tested wells in Tulkarem complied with the WHO guideline;while nitrate (NO3) and potassium (K) concentrations exceeded the permissible concentra-tions.

汉阿交替传译在产出过程中常常会出现不当停顿问题,这是影响口译质量的重要因素。译员在交替传译的过程中,由于多种原因,会产生译语不当停顿,影响产出语流,降低口译效率与质量,给听众的理解造成障碍,影响对译员的信任,同时也影响译员的自信。因此,笔者选择不当停顿作为研究和分析的主题,总结了造成笔者在模拟会议口译中出现不当停顿的原因并提出应对策略。本文以2020年周小川在“外滩金融峰会”演讲的模拟会议为例,笔者在模拟会议上负责整场会议的交传,笔者尽力做到清楚完整的翻译。会议完成后,笔者对源语和译语进行了转写和比较,分析了笔记和译语中不当停顿的例子,并研究了成因及对策。通过分析发现,案例中出现不当停顿的主要原因有对源语同音近音词辨析能力不足、笔记不当、译语标准语掌握不足、心理素质欠佳。为应对不当停顿、提高口译质量,笔者给出了相应策略:提高源语同音近音词的辨析能力、完善笔记系统、提升译语标准语表达能力、提升译员的心理素质。笔者参考了相关文献,并结合自身案例撰写本论文,希望本文案例中的不当停顿成因分析和解决策略,能帮助阿拉伯口译学习者更准确流利地进行汉阿口译,减少不当停顿,提高汉阿口译质量。
