Green Roofs For Grey Water Treatment – Comparative Study Of Economic And Environmental Impacts, Shaden S. Attia

Theses and Dissertations

Cities are under more pressure than ever to use sustainable methods for managing water and other resources because of urbanization, climate change, and a lack of water. Standard greywater treatment systems (SGTSs) work well, but they use a lot of resources and don't provide a lot of ecosystem services. Greywater-treating green roofs (GTGRs) have emerged as a promising Nature-Based Solution (NBS), combining wastewater recycling with benefits like regulating temperature, reducing greenhouse gas (GHG) emissions, and reducing the urban heat island (UHI) effect. Even with this potential, there is still not enough real-world research on how GTGRs affect both the economy …

Prephiral Bacterial Infectious Agent Triggers Neuroinflammatory Responses And Neurobehavioral Impairment In Wild-Type Mice, Hadeer Atalah

Theses and Dissertations

Neurodegenerative diseases, including Alzheimer's and Parkinson's, present an increasing global challenge, with chronic neuroinflammation identified as a principal factor alongside genetic, environmental, and infectious influences (Boyd et al., 2022).  Epidemiological data associate bacterial infections with a 40% heightened risk of Parkinson's disease; however, the mechanisms—especially the direct connection between peripheral sepsis and the silent onset of central nervous system pathology absent acute meningitis—are inadequately investigated (Smeyne et al., 2021), particularly concerning common pathogens like Klebsiella pneumoniae in high-burden areas such as Egyptian ICUs, where it constitutes 30% of cases (Alkompoz et al., 2023). This study filled the gap by creating …

Hardness Of (Hf,Ti,W,Zr)B2/(Hf,Ti,W,Zr)C-Based Ceramics With Varying Wb Content, Suzana Filipović, William G. Fahrenholtz, Gregory E. Hilmas, Nina Obradović, Stefano Curtarolo

Materials Science and Engineering Faculty Research & Creative Works

Compositionally complex (Hf,Ti,Zr,W)B₂/(Hf,Ti,Zr,W)C-based ceramics were produced with different boride and carbide phase contents by varying the C/B₄C molar ratio used in boro/carbothermal reduction. A monoboride phase based on WB was detected in all compositions. As the C/B₄C ratio was varied, the WB content decreased from 23.7 vol% for a C/B₄C ratio of 6.0–15.3 vol% for a C/B₄C ratio of 10.3. Further increases in the C/B₄C ratio increased the WB content. The monoboride phase contained mainly W and Ti in a solid solution with the nominal composition of (W …

A Critical Examination Of International Education Mobility Regimes: Comparative Insights From Vietnamese Students In Canada, France, And The United Kingdom, Anne-Cécile Delaissea, Tamsin Barberb, Suzanne Huota

Journal of Comparative & International Higher Education

Amidst the neoliberal commodification of international education, countries have taken various approaches to governing international students’ mobilities. This paper examines Vietnamese students’ navigation of different ‘regimes of mobility’ in Canada, France and the United Kingdom (UK). Drawing on Manderscheid’s (2020) “critique of mobility” we highlight how these regimes vary not only in openness, but also in the power dynamics they perpetuate. Based on two qualitative interpretive studies, including 25 interviews with Vietnamese students in Vancouver, Paris, and the UK (London, Northampton and Aberdeen), our thematic analysis addresses how mobility regimes affect students’ choice of destination, legal status, and post-graduation plans. …

Parallel Concepts Found In The Thousand And One Nights And Sufi Hagiography, Walaa Kamal Emam Kamel

Theses and Dissertations

This thesis argues that The Thousand and One Nights functions as more than mere populist entertainment; rather, it constitutes a literary corpus imbued with Sufi mystical epistemologies that reflect the spiritual quests and Sufi concepts evident in hagiographical traditions. Through discourse and intertextual analysis of two Nights stories, “The City of Brass” and “The Porter and the Three Ladies of Baghdad,” alongside Farīd al-Dīn ʿAṭṭār’s Tadhkirat al-awliyāʾ, this study demonstrates how shared rhetorical strategies—specifically David Pinault’s Leitwörter analysis and L.A. Paul’s Transformative Experience concept—reveal a narrative and rhetorical emphasis on the metamorphosis of the self from worldly attachment toward …

In Her Words: The Silent Battles Of Egyptian Women With Breast Cancer, Nada Mohamed Ahmed Hassan Nh

Theses and Dissertations

This study investigates the emotional, social, and economic difficulties encountered by Egyptian women from middle- to working-class origins after a breast cancer diagnosis. Despite being a worldwide health concern, local cultural, institutional, and economic circumstances have a significant impact on the lived consequences of breast cancer. Women's post-diagnosis experiences in Egypt are greatly exacerbated by deeply ingrained gender stereotypes, stigma associated with cancer, and systemic injustices in the healthcare system. This research emphasizes women's situated knowledge and views their bodily experiences as crucial sources of insight into larger societal power relations. It is based on feminist perspective theory, especially the …

Nlp-Based Comparative Assessment Of Clauses Quantifying Risk Transfer In Construction Contracts, Hoda M. Elshamy

Theses and Dissertations

Employers in the construction industry mostly deviate from standard contract forms such as FIDIC and NEC, by introducing alterations to the contract conditions that shift a great portion of risks from the client to the contractor. Originally, these risks were distributed more equitably between all contracting parties in the standards forms. The imbalances in the contractual conditions create fertile ground for conflicts, and if not resolved, will escalate to disputes during the project execution phase, leading to significant cost overruns and time delays. The contractors, therefore, attempt to restore the original balance through making amendments to the communicated contract, through …

Law And The (Re)Production Of Class Hierarchies In Egypt, Ahmad Abdelnaby

Theses and Dissertations

This thesis investigates how Egypt’s legal system, structurally tilted toward the elite and constitutive of inequality, has interacted with the country’s entrenched culture of class-based discrimination to produce a legal culture uniquely comfortable with hierarchy. It contends that class-based discrimination in Egypt has evolved from a social prejudice into a juridical condition, one in which the law does not merely mirror inequality but actively constructs and rationalizes it. By examining the intersection between legal structure and Egypt’s entrenched moral order of class-based discrimination, the study reveals a legal culture that no longer hides its hierarchies behind the veil of neutrality …

Lived Experiences Of Limited Sexual And Reproductive Health Education Among Egyptian Women, Nada Abdelhamid

Theses and Dissertations

In Egypt, sexual and reproductive health (SRH) education remains largely absent from national education and youth policy frameworks, reflecting a broader governance gap at the intersection of education, health, and gender policy. This qualitative study explores how the lack of formal sexuality education shapes women’s knowledge, perceptions, and sexual and reproductive experiences across the life course, drawing on in-depth interviews with twelve Egyptian women from diverse marital backgrounds. The findings point to persistent gaps in basic SRH knowledge, early exposure to shame and stigma, and reliance on informal and often unreliable sources of information, which participants linked to fear of …

Two Decades Since Cms V. Argentina: Concession Contracts, Necessity Doctrine, And The Imf’S Impact On Sovereign Economic Governance, Esraa S. Saied Abdallah

Theses and Dissertations

In the evolving landscape of international trade, particularly within the framework of Bilateral Investment Treaties (BITs), the primary aim has been to promote and protect foreign investment. The 1980s witnessed a notable increase in investment treaties, coinciding with a global shift toward privatization that was significantly influenced by the impact of international financial institutions, including the International Monetary Fund (IMF) and the World Bank. By the 1990s, BITs had evolved to offer specific guarantees aimed at reducing the risks foreign investors faced in host states. However, despite the growth and transformation brought about by foreign investments, disputes arising under investment …

The results indicate that education and skill mismatches are common among employed Gen Z, with a considerable percentage of 38-45%. This is despite the fact that …

The Impact Of Violent Content Media Exposure On Behavioral Outcomes: The Mediating Role Of Media Engagement, Melissia Emad Eskander

Theses and Dissertations

This study explores how repeated exposure to violent content in films, television series, and video games may influence behavioral outcomes among Egyptian media consumers. Drawing on the General Aggression Model, Social Learning Theory, and Cultivation Theory, it examines how individual interpretation, emotional involvement, and narrative absorption mediate the effects of media violence. It also considers how personality traits shape audience responses, specifically aggression, empathy, and narrative immersion.

A mixed-methods approach was adopted. A structured survey of 200 Egyptians aged 18 and above assessed media exposure, aggression, empathy, narrative engagement, and behavioral outcomes. In parallel, a content analysis of Egyptian films …

Inspect: Intelligent Node-Based System For Ifc Processing And Evaluation, With Conversational Tool Support —Llmassisted Natural Language Ifc Querying, Basel Abdelshaheid

Theses and Dissertations

Industry Foundation Classes (IFC) enables the open exchange of Building Information Models, yet effective validation of real-world IFC deliveries remains challenging. Project models frequently contain incomplete, inconsistent, or incorrectly exported metadata, and explicit IFC relationships are often missing or degraded during conversion from proprietary formats. Many validation questions are inherently spatial, including connectivity, containment, proximity, and clashes, and therefore cannot be answered reliably from properties alone. As a result, federated model validation is often slow, fragmented across tools, and dependent on specialized IFC expertise.

This challenge is increasingly important for coordination, quality assurance, and information management across disciplines and lifecycle …

Scalable And Fault-Tolerant Network Architectures For Real-Time Video Transmission In Industrial Networked Control Systems, Moustafa Awad

Theses and Dissertations

This thesis addresses the challenge of transporting supervisory video alongside time-critical control traffic in industrial Networked Control Systems (NCS) without violating stringent real-time constraints. A simple yet scalable network architecture is developed and evaluated for a plant-level deployment comprising three interconnected workcells with sensors, controllers, actuators, and cameras. The design explicitly accommodates bandwidth-intensive video streams while preserving the responsiveness of watchdog/control traffic. Analytical delay modeling decomposes end-to-end latency into transmission, propagation, processing, and queuing components, and Riverbed-based simulations are used to validate the model under realistic mixed-traffic conditions. A traffic-engineering strategy - phase-shifting supervisory camera transmissions - effectively desynchronizes frame …

Groove Goes The Distance: An Initial Inquiry Into Jazz Music In Egypt, Farida Gohar

Theses and Dissertations

Jazz music has been a historically contentious site of social, cultural, and political signification. From the violent subjugation that characterized its origins and aspirational freedom that animated its practice, to its transformation into a distinctly “American” music instrumentalized by the US State Department to counter Soviet influence, jazz’s capacity for the inscription of meaning is vast and regularly cause for debate. The particular configuration of jazz music in Egypt is no less complicated although seldom studied. This thesis ventures an initial mapping of the dynamics and negotiations that historically defined the initiation of “Egyptian” jazz, as well as the ones …

An Ethnographic Exploration Of The Lived Experiences With Gynecologic Cancers, Norma Naser Aldeen

Theses and Dissertations

Abstract

This thesis stays close to conversations with nine women who spoke about living with and through gynecologic cancers, from moments of finding out, through treatment, and into what follows. These encounters unfolded primarily through digitally mediated exchanges across Baalbek, Beirut, and other translocal settings shaped by distance and movement. Rather than approaching illness as a bounded biomedical event, this thesis attends to how gynecologic cancer is narrated as something that lingers—pressing into everyday life through bodily sensations, altered rhythms, and ongoing recalibrations of care, responsibility, and what remains possible.

Across these encounters, care rarely appears as a stable system …

Refugees In Egypt: State Framing, Ministerial Narratives, And The Politics Of Representation On Social Media, Habiba Kohail
