Refaat Alareer’s “If I Must Die”: The Death of the Author, the Afterlife of the Tale
No full textThis article traces the performative role of tales and storytelling in late Refaat Alareer’s life, career, (creative) writing, activism, and death. It ultimately examines this performativity’s intensification and culmination in Alareer’s Saidian late-style poem “If I Must Die.” The article combines close textual analysis and comparative literary criticism to investigate the intricate relationship between storytelling, mortality, and resistance in Alareer’s poem. Paying attention to nuance, the article examines the poem’s intertextual connections with Claude McKay’s “If We Must Die” (1919) to demonstrate how Alareer transforms storytelling into a powerful mode of cultural survival and a means of transcending physical destruction and preserving collective memory in the face of systematic oppression. Additionally, the research traces Alareer’s evolving conceptualization of storytelling from a personal imperative to a collective form of resistance, culminating in “If I Must Die” whose stylistic and thematic treatment of his impending death anchor his poem locally/nationally, namely in Gaza/Palestine
Advanced Atmospheric Water Vapor Dial Detection System
No full textMeasurement of atmospheric water vapor is very important for understanding the Earth\u27s climate and water cycle. The remote sensing Differential Absorption Lidar (DIAL) technique is a powerful method to perform such measurement from aircraft and space. This thesis describes a new advanced detection system, which incorporates major improvements regarding sensitivity and size. These improvements include a low noise advanced avalanche photodiode detector, a custom analog circuit, a 14-bit digitizer, a microcontroller for on board averaging and finally a fast computer interface.
This thesis describes the design and validation of this new water vapor DIAL detection system which was integrated onto a small Printed Circuit Board (PCB) with minimal weight and power consumption. Comparing its measurements to an existing DIAL system for aerosol and water vapor profiling validated the detection system
The Vertical Greening Envelope and its Effect on Energy Consumption Efficiency in a Residential Building, Case Study: Twin House, 6th of October City
No full textEgypt has suffered from Energy problems, especially in the last 10 years, as it transformed from exporter to importer of oil and gas. [1]. The residential buildings consume over 40% of Electricity. Moreover, most of this consumption is for using HVAC systems to reach the thermal comfort inside spaces, as it used non-environmental material, which led to maximizing heat gain. The study aims to measure the vertical greening envelope and its variables such as; LAI and air gap effect on energy consumption. The research methodology includes reviewing the literature and methods of Vertical greening systems (VGS) and their types, plantations… Etc. and its effect on the buildings’ external envelope to achieve maximum energy efficiency. A practical study was carried out by simulating one direction Town House on 6th October, Egypt, every 30° starting from the north using a design-builder simulation program.The research compared the energy consumption of the building’s initial case with 12cm concrete bricks and VGS installation with a 60cm air-gap. The VGS reduced energy consumption by 19.6:29% in the different installation directions, and 240° SW recorded the highest saving in the case of LAI was 2.0 and to measure the effect of LAI beside the installation orientation the LAI 2.0 compared to LAI 4.0 in 240° SW and the saving has increased to 32.3%. In the case of no air-gap, the saving was 29.3% which means that the LAI and air gap distances affected the performance of VGS as the installation direction did
Utility of the exercise electrocardiogram testing in sudden cardiac death risk stratification
No full textBackground Sudden cardiac death (SCD) remains a major public health problem. Current established criteria identifying those at risk of sudden arrhythmic death, and likely to benefit from implantable cardioverter defibrillators (ICDs), are neither sensitive nor specific. Exercise electrocardiogram (ECG) testing was traditionally used for information concerning patients' symptoms, exercise capacity, cardiovascular function, myocardial ischemia detection, and hemodynamic responses during activity in patients with hypertrophic cardiomyopathy. Methods We conducted a systematic review of MEDLINE on the utility of exercise ECG testing in SCD risk stratification. Results Exercise testing can unmask suspected primary electrical diseases in certain patients (catecholaminergic polymorphic ventricular tachycardia or concealed long QT syndrome) and can be effectively utilized to risk stratify patients at an increased (such as early repolarization syndrome and Brugada syndrome) or decreased risk of SCD, such as the loss of preexcitation on exercise testing in asymptomatic Wolff-Parkinson-White syndrome. Conclusions Exercise ECG testing helps in SCD risk stratification in patients with and without arrhythmogenic hereditary syndromes. © 2014 Wiley Periodicals, Inc.Adler A, 2012, HEART RHYTHM, V9, P901, DOI 10.1016-j.hrthm.2012.01.026; Atta S, 2012, J CLIN EXP CARDIOLOG, V3, P223; Bastiaenen R, 2013, HEART RHYTHM, V10, P247, DOI 10.1016-j.hrthm.2012.10.032; Bershader RS BC, 2007, HEART RHYTHM, V4, pS138; Calloe K, 2013, CIRC-ARRHYTHMIA ELEC, V6, P177, DOI 10.1161-CIRCEP.112.974220; Chattha IS, 2010, HEART RHYTHM, V7, P906, DOI 10.1016-j.hrthm.2010.03.006; Cohen MI, 2012, HEART RHYTHM, V9, P1006, DOI 10.1016-j.hrthm.2012.03.050; Elhendy A, 2002, AM J CARDIOL, V90, P95, DOI 10.1016-S0002-9149(02)02428-1; Engel G, 2004, CURR PROB CARDIOLOGY, V29, P365, DOI 10.1016-j.cpcardiol.2004.02.007; Frolkis JP, 2003, NEW ENGL J MED, V348, P781, DOI 10.1056-NEJMoa022353; Gimeno JR, 2009, EUR HEART J, V30, P2599, DOI 10.1093-eurheartj-ehp327; Goldberger Jeffrey J, 2008, Heart Rhythm, V5, pe1, DOI 10.1016-j.hrthm.2008.05.031; Haissaguerre M, 2008, NEW ENGL J MED, V358, P2016, DOI 10.1056-NEJMoa071968; HINDMAN MC, 1973, ANN INTERN MED, V79, P654; Horner JM, 2011, HEART RHYTHM, V8, P1698, DOI 10.1016-j.hrthm.2011.05.018; Josephson ME, 2000, ANN INTERN MED, V133, P901; Kentta T, 2012, HEART RHYTHM, V9, P1083, DOI 10.1016-j.hrthm.2012.02.030; Lahat H, 2001, AM J HUM GENET, V69, P1378, DOI 10.1086-324565; Laitinen PJ, 2001, CIRCULATION, V103, P485; Makimoto H, 2010, J AM COLL CARDIOL, V56, P1576, DOI 10.1016-j.jacc.2010.06.033; MARIEB MA, 1990, AM J CARDIOL, V66, P172, DOI 10.1016-0002-9149(90)90583-M; Meli AC, 2011, CIRC RES, V109, P281, DOI 10.1161-CIRCRESAHA.111.244970; Morshedi-Meibodi A, 2004, CIRCULATION, V109, P2417, DOI 10.1161-01.CIR.0000129762.41889.41; O'Neill JO, 2004, J AM COLL CARDIOL, V44, P820, DOI 10.1016-j.jacc.2004.02.063; Priori SG, 2002, CIRCULATION, V106, P69, DOI 10.1161-01.CIR.0000020013.73106.D8; Priori SG, 2013, EUROPACE, V15, P1389, DOI 10.1093-europace-eut272; Raju H, 2011, HEART RHYTHM, V8, pS41; Roux-Buisson N, 2012, HUM MOL GENET, V21, P2759, DOI 10.1093-hmg-dds104; Steinhaus DA, 2012, AM HEART J, V163, P125, DOI 10.1016-j.ahj.2011.09.016; Sy RW, 2011, CIRCULATION, V124, P2187, DOI 10.1161-CIRCULATIONAHA.111.028258; Tseng ZH, 2009, HEART RHYTHM, V6, P1315, DOI 10.1016-j.hrthm.2009.06.034; van der Werf C, 2010, CIRC-ARRHYTHMIA ELEC, V3, P96, DOI 10.1161-CIRCEP.109.877142; Watanabe J, 2001, CIRCULATION, V104, P1911; Zheng ZJ, 2001, CIRCULATION, V104, P2158, DOI 10.1161-hc4301.098254; Zipes DP, 2006, J AM COLL CARDIOL, V48, pe247, DOI DOI 10.1016-J.JACC.2006.07.0100

Pilot study for early prognosis of Azoospermia in relation to Y-STR Profiling
No full textAbstractBackgroundAzoospermia constitutes 20% of male infertility situations and affects 1% of the total male population (Jarvi et al., 2010). This condition is classified into three major types; pre-testicular, testicular and post-testicular Azoospermia (Sermondade et al., 2012). Genetic defects causing Azoospermia are due to chromosomal or non-chromosomal alterations on the Y-Chromosome (Lee et al., 2011). Initial diagnosis of Azoospermia is established when no spermatozoa are detected on microscopic examination of semen (World Health Organisation, 1999).ObjectiveTo evaluate the correlation of Y-STR Profiling results and the prevalence of Azoospermia, to help for early prognosis of Azoospermia before puberty.MethodsBuccal swab samples were taken from two groups of individuals (50 fertile and 50 Azoospermic patients), then DNA was isolated using QIAamp DNA Micro kit. DNA quantification was done using a Real-time PCR utilizing Quantifiler Kit. PCR was done using PowerPlex® Y PCR Amplification Kit, then amplified products were typed using a 3130 Genetic Analyzer.ResultsFive haplotypes in four different Y-STR loci were found to possess significantly higher occurrence percentages in Azoospermic than in fertile Saudi individuals, which can serve as a group of pre-diagnostic markers for early prognosis of Azoospermia in Saudi population.ConclusionThere was a significant correlation of Y-STR Profiling results and the prevalence of Azoospermia condition, which supports the idea of using Y-STR Profiling in early prognosis of Azoospermia
Under siege : remembering Leningrad, surviving Gaza
No full textHow does one communicate what life is like under siege? Much has been written to describe the besieged Gaza Strip yet Al-Shabaka Policy Member Ayah Abubasheer and Guest Author Esther Rappaport bring new insights and perspectives in this Roundtable. Ayah Abubasheer lives under the siege of Gaza at the present time; Esther Rappaport’s family lived under the siege of Leningrad during World War II. Ayah and Esther came to know each other through social media during the Summer 2014 attack on Gaza and first thought of writing this piece during this war. In their reflections and analysis of the two sieges they ably communicate the stark reality of life under siege. The reflections of each of the two authors are given in their own voice. They also provide some additional factual information and background, and this part of their discussion, conversation, and argument is presented in the voice of a “narrator”
