Low-Carbon Concrete For Sustainable Construction: A Comprehensive Review Of Performance Characteristics, Implementation Challenges, And Decarbonization Pathways, Fazel Azarhomayun, Jingjie Wei, Kamal H. Khayat

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Reducing the carbon footprint of concrete has become a central objective in sustainable construction. Low-carbon concrete (LCC), developed primarily through clinker reduction, supplementary cementitious materials, and alternative binder strategies, offers a promising route for lowering embodied emissions while maintaining the performance requirements of structural concrete. This comprehensive review consolidates the current state of knowledge on LCC, identifies critical research and implementation gaps, and examines its material composition, mixture-design methodologies, performance characteristics, structural applications, implementation challenges, and decarbonization pathways. Single-SCM systems have been reported at clinker-replacement levels approaching 50%, although durability at these replacement levels, particularly carbonation resistance, remains system- and …

Atypical Presentation Of Acromegaly With Isolated Finger Pain Despite Severe Biochemical Disease, Neha Syed, Nathan Fletcher, Allison Isabelli, Tharani Rajeswaran

Advocate GME

Introduction: Acromegaly, typically caused by a pituitary somatotroph adenoma, often presents insidiously. The average diagnostic delay is 7-10 years due to the slow progression of somatic changes. While classic features include frontal bossing and macroglossia, subtle musculoskeletal symptoms can be the primary presenting complaint. We present a case of severe biochemical acromegaly where localized finger pain and swelling were the initial manifestations, masking a significantly elevated IGF-1 level. Case Presentation: A 45-year-old woman with an 8-year history of prediabetes presented for evaluation of persistent, localized pain and swelling in a single digit of the right hand.

Objects Of Atrocity: Material Culture And The Challenges Of Difficult Histories, Robert M. Ehrenreich, Jane E. Klinger, Gabriel H. Pizzorno, Caroline Sturdy Colls

Purdue University Press Books

The vast majority of people throughout history have left few written traces. That is especially the case for those who were brutally forced from their homes, stripped of their possessions, and swiftly imprisoned, enslaved, or murdered. Objects of Atrocity: Material Culture and the Challenges of Difficult Histories addresses how we return humanity to these people in order to avoid their erasure from history. Academics and practitioners from a variety of disciplines and cross-disciplinary approaches grapple with the challenges and possibilities relating to the collection, conservation, storage, and display of objects in the aftermath of mass atrocities. This collection confronts a …

Work Precarity, Mental Health, And Performance Among Humanitarian Aid Workers In Egypt Post-2025 U.S. Funding Reduction, Mariam Allam

Theses and Dissertations

The humanitarian sector is increasingly characterized by precarious employment conditions and work precarity, including short-term contracts, unclear renewal terms, inadequate compensation, heavy workloads, and job insecurity, exacerbated by volatile donor funding. The 2025 U.S. funding cuts have intensified these vulnerabilities, particularly in countries like Egypt, with massive humanitarian operations because of being a significant destination for asylum applications and one of the largest refugee host countries. Despite the prevalence of precarious work in the humanitarian sector, limited research examines its effects on workers' mental health and work performance, especially during funding crises. This qualitative study explores the perceived effect of …

Integrative Assessment Of Body Composition And Micronutrient Status In An Adult Egyptian Population, Roua Aref Nouh

Theses and Dissertations

Integrative Assessment of Body Composition and Micronutrient Status in an Adult Egyptian Population: A Functional and Biochemical Approach

Obesity and metabolic dysfunction are increasingly recognized as heterogeneous conditions that cannot be sufficiently characterized by body mass index (BMI) alone. Alterations in body composition, particularly central adiposity and skeletal muscle mass, may coexist with micronutrient imbalances even among individuals who fall outside conventional BMI-based obesity classifications. In clinical settings, such metabolic vulnerability is frequently accompanied by non-specific functional symptoms, highlighting the need for integrative assessment approaches that extend beyond weight-centered metrics. This cross-sectional study aimed to investigate the associations between micronutrient …

Philosophia From Dialectic To Dying Before Death: Traces Of Plato’S Spirit In The Encounters Between The Falāsifa, Mutakallimūn, And Sūfiyya, Fadhil Yunus Alsagoff

Theses and Dissertations

This thesis offers a fresh approach to the question “What is philosophy?” by reconsidering Plato’s vision of philosophiaand seeking its traces in the encounters between the Falāsifa, the Mutakallimūn, and the Sūfiyya of the classical Muslim world. I argue that Plato’s true legacy lies in a vision of philosophia as dialectical inquiry that ultimately leads – due to the inextricable limitations of propositional language – to aporia and what he called “practicing for dying and death.” I then argue that this vision of philosophia finds resonance in the classical Muslim world in the embodied encounters between …

The Experience Of Newly Formed Syrian Female-Headed Households Refugees In Egypt: Challenges And Opportunities, Wasim Dia

Theses and Dissertations

This thesis examines the lived experience of Newly Formed Syrian Female-Headed Households in Egypt. It focuses on how the extended displacement reshapes gender roles, decision-making, and survival strategies. Since the beginning of the Syrian conflict in 2011, extensive family separation, death, disappearance, and male migration have occurred, leading to a significant rise in female-headed Syrian refugee households. As a result, displacement has intensified women’s vulnerability, generating new responsibilities and limited spaces for agency, especially within restrictive legal and socio-economic environments.

Based on in-depth qualitative interviews conducted in 2023, this research explores how Syrian refugee women navigate everyday life in Egypt …

Sense Of Belonging Among Undergraduate Students At The American University In Cairo: Demographic Trends, Barriers And Facilitators, Lamiaa M. Mohamed

Theses and Dissertations

A sense of belonging is widely recognized as a key determinant of undergraduate students’ academic success, well-being, and persistence in higher education. However, existing research is largely grounded in Western contexts and often emphasizes institution-level measures, with limited attention to how belonging is experienced and constructed by students in non-Western settings. This study examines undergraduate students’ sense of belonging at the American University in Cairo, focusing on factors that shape belonging and institutional practices that may strengthen it. Using a sequential mixed-methods design, the study examined 87 responses from a quantitative survey adapted from the University Belonging Questionnaire, followed by …

Humanitarianism Through Alan Kurdi Photograph: A Discourse Of Governing Suffering, Nada Mahmoud

Theses and Dissertations

Humanitarianism has become one of the powerful languages of modern times, in which compassion, ethics, and moral obligations are mediated to alleviate suffering. This thesis investigates humanitarianism not exclusively on the basis of its moral sentiments but on its functioning as a system of power that governs people’s conduct. It examines how different technologies of power feed into the operationalization of humanitarianism to transform it into a system for governing suffering. By decoding the elements of its power, the thesis aims to understand humanitarian reason through the humanitarian loop, from generating knowledge, categorization and representation, to the legal and normative …

Energy Efficient Load Balancing In Multi-Band Cellular Networks Via Reinforcement Learning, Ahmed Shoukry El Soukkary

Theses and Dissertations

This thesis investigates energy-efficient load balancing in homogeneous multi-band cellular networks through the joint design of user association (UA) and transmit power allocation (PA). The original mixed-integer nonlinear formulation is decomposed into two coupled yet tractable subproblems: a UA stage and a PA stage for high-frequency bands. For UA, a SINR-ratio-based heuristic is proposed to prioritize users that are most sensitive to suboptimal band assignments, and it is benchmarked against a Max- SINR baseline. For PA, the high-band power control problem is addressed using reinforcement learning, where a Proximal Policy Optimization (PPO) agent learns power levels and band-activation decisions under …

Scruples Before Religion: Muslim Waraʿ Of The Formative Period, Omar Laaroussi

Theses and Dissertations

This thesis studies the conceptual history of waraʿ and its role as a normative paradigm existing in the formative centuries of the Islamic world. To do so, I consider the Hellenic concepts that ground Near Eastern understandings of virtue and piety before the rise of Islam. This, I then use to contextualise a focused discussion on the textual history of waraʿ before moving on to discuss its properties in a ascetic social-world through the analysis of those very texts. I attempt to place those properties in conversation with modern philosophers’ work on disciplinary regimes and their impacts upon the self. …

Parental Gender Bias In Youth Employment Standards: Evidence From Upper Egypt, Mahmoud Saeed

Theses and Dissertations

Youth unemployment remains a critical challenge in Egypt, with female labor force participation among the lowest globally. While structural factors such as limited job creation and public sector contraction are well-documented, the role of family-level decision-making in constraining women's labor market entry has received limited quantitative attention. This thesis examines parental gender bias in employment standards in Upper Egypt, investigating whether and how parents impose systematically different job requirements for daughters compared to sons. Using primary survey data from 17,284 unemployed youth aged 18-35 across six governorates, paired with responses from their parents, this study analyzes parental preferences across six …

Mobilizing Social Capital In Social Entrepreneurship: Strategies, Networks, And Growth In The Egyptian Context, Doaa Alaa

Theses and Dissertations

This thesis examines how social entrepreneurs in Egypt strategically mobilise social capital to access resources, legitimacy, and opportunities within a fragmented and institutionally ambiguous ecosystem. Drawing on qualitative case studies of eight legally registered, mission-driven for-profit enterprises, the study analyses how founders build and leverage offline and online networks through practices such as emotional bonding, community formation, knowledge sharing, symbolic positioning, ecosystem engagement, and digital presence. Through thematic analysis of semi-structured interviews and secondary data, the research identifies a set of relational strategies that function as core mechanisms for entrepreneurial growth in contexts where formal support structures and legal definitions …

Tuning Ion Mobility And Molecular Confinement In High-Performance Polymer Electrolytes For Energy Storage, Ezzeldien Yousef Muhammed Yousef

Theses and Dissertations

This research addresses the critical energy density limitations of aqueous supercapacitors, which are traditionally constrained by the narrow electrochemical stability window (ESW) of water 1.23 V. By employing two distinct molecular engineering strategies, this study developed high-performance electrolyte systems that significantly extend voltage stability and thermal resilience.

The first system, CsBr@PAM/HA, utilizes a polyacrylamide and hyaluronic acid hydrogel matrix. This system exploits the chaotropic nature of Cs⁺ ions to disrupt the aqueous hydrogen-bonding network, enhancing ionic conductivity to 104 mS cm^-1. Through systematic salt screening, CsBr was identified as the optimal electrolyte, enabling a stable 2.0 V …

Social Identity And Language Learning/Teaching Trajectories: Egyptian English Teachers’ Reflections On Being Taught By Native English- Speaking Instructors, Asmaa Mohamed Badawy

Theses and Dissertations

This study explores how teacher social identity is shaped by Egyptian English teachers’ past learning experiences, particularly in relation to native and non-native English-speaking teachers. It seeks to understand how these experiences influence teachers’ perceptions of themselves within English-speaking contexts and how they make sense of dominant language ideologies surrounding nativeness. The study is guided by the following research questions: how participants perceive their sense of social belonging within English-speaking contexts; how ‘native’ and ‘non-native’ English teachers understand and interpret nativeness; and how past educational and social experiences shape teachers’ sense of ownership and legitimacy. Situated within the framework of …

How Disability Inclusion Shapes Student Experiences In Egyptian Public Universities, Ramez Maher

Theses and Dissertations

The inclusion of students with disabilities in higher education is a critical aspect of equity, social justice, and human rights, particularly in Egypt, where systemic barriers continue to hinder access to education for this demographic. Despite the enrollment of approximately 19.4 million students in 2018, only 38,135 students with disabilities were admitted, highlighting the significant challenges they face in accessing higher education.   Through a qualitative approach employing reflexive thematic analysis, this study explores the interplay of institutional policies, cultural attitudes, and accessibility challenges that affect the educational experiences of students with disabilities in Egyptian public universities. The analysis of 21 …

From Aspiration To Obligation: A Contractual Sustainability Framework For The Egyptian Construction Industry, Salma Ali

Theses and Dissertations

The construction industry is responsible for approximately 40% of global energy consumption and 35% of total waste generation, making it one of the most significant contributors to the global sustainability challenge. In Egypt, that challenge takes a specific contractual form. Egypt’s construction sector contributes approximately 23% of national energy consumption, yet the survey findings reveal that 63.5% of construction professionals report that sustainability clauses rarely or never appear in contracts, and only 11.5% confirm the presence of enforceable provisions with measurable targets. This gap is structural rather than attitudinal. Competitive procurement penalises voluntary sustainability investment, and without contractual obligation, awareness …

The Informal Impact Of The Headscarf Ban On Veiled Students’ Everyday University Experiences In Paris, Farah K. Lotfy

Theses and Dissertations

This study examines the informal impact of the 2004 headscarf ban on the everyday university experiences of veiled students in Paris. Although the ban applies formally to public schools rather than universities, the wider social climate surrounding laïcité and the veil continues to influence how veiled students experience visibility, belonging, and participation in higher education.

Using a qualitative approach based primarily on semi-structured interviews, supported by informal observations conducted within university spaces in Paris, the study explores how exclusion is experienced through stereotypes, scrutiny, social discomfort, self-monitoring, and anticipation of discrimination rather than through formal university policy. The research focuses …

Engineering Nanoelectrocatalytic Systems For Co2 And Nitrate Conversion Into Value-Added Chemicals, Abdelrahman Mohamed Abdelmohsen

Theses and Dissertations

The thesis addresses two major related environmental crises: nitrate pollution of water systems and the ever-increasing levels of atmospheric carbon dioxide. Both challenges are closely linked to anthropogenic disturbance of nitrogen and carbon cycles and require sustainable, energy efficient mitigation techniques. In this study, we investigate electrochemical conversion routes as a unified approach to convert these pollutants into value-added compounds: ammonia (NH3) via nitrate reduction (NO3-RR) and ethylene (C2H4) via carbon dioxide reduction (CO2RR). The first half of this work deals with the design and engineering of Cu-Zn alloy electrocatalysts for efficient NO3-RR. Tuning the alloy composition and surface nanostructure …

Flexible-Mode Multi-Skilled Resource-Constrained Project Scheduling Problem With Setup Times: Application In The Oil And Gas Industry, Safinaz M. El Dawody

Theses and Dissertations

Turnaround maintenance (TAM) in the petroleum refining sector requires coordinating geographically dispersed project portfolios under stringent resource, schedule, and budget constraints. Conventional scheduling models treat tasks in isolation, failing to account for shared resources, crew fatigue, or inter-site transit. To bridge this gap, this study introduces and empirically validates a Flexible-Mode Multi-Skilled Resource-Constrained Project Scheduling Problem with Setup Times (FM-MS-RCPSP-ST). Applied to a real-world portfolio of 76 TAM projects across five governorates in Egypt, the framework is operationalized through an 11-stage pipeline integrating NSGA-II multi-objective optimization, GIS-based routing, and 500-trial Monte Carlo disruption simulations.

Results demonstrate that incorporating mandatory crew-rest …

The Effect Of Mwcnt-Oil Impregnation Of Sintered Components On Their Wear And Corrosion Resistance, Maha Khaled Abdelfadeel

Theses and Dissertations

Powder Metallurgy (PM) offers an advantageous route for manufacturing complex and near net-shape components. Their inherent interconnected porosity that promotes the action of self lubrication compromises their structural integrity by creating pathways for corrosion and excessive wear. This research investigates the efficacy of Multi-Walled Carbon Nanotubes (MWCNTs) as a nano additive within the impregnating base oil (SN-150 base oil). An experimental matrix was designed to evaluate the influence of MWCNTs with different concentrations of 0.05, 0.1, and 0.2 wt.% and ultrasonic dispersion with varying sonication times of 30 and 60 minutes on the tribological and electrochemical performance of sintered steel …

Who Moderates? A Polycentric Framework For Allocating Regulatory Responsibility In Online Content Moderation, Farh A. El Wishi

Theses and Dissertations

The question of who is responsible for content moderation on the internet remains one of the key topics relating to internet governance. Legislation has been adopted, platforms have utilized self-regulation methods, and users have flagged and reported content, all often happening simultaneously, yet rarely according to any coherent principle for deciding which actor should bear primary responsibility for which aspect of the problem. This research argues that the absence of a principled allocative framework is the central governance failure of the internet's regulatory history, and that addressing it requires a structured distribution of regulatory responsibility across the three actors who …

Michigan's Automotive Workforce Transition, Erik Vasilauskas, Michael Horrigan
