This thesis studies the transformations of architecture and social life in the city of Balat in Dakhla oases in the Western Desert in Egypt. I explore the inhabitants' conceptions of modernity in relation to architecture and other aspects of social life. I investigate how the prevalent discourses of modernity that the inhabitants encounter through their interaction with state institutions, stay in Cairo, and exposure to media products inform their practices towards architecture and other aspects of social life. Moreover, I investigate how such discourses are received and appropriated by the people of Balat.I argue that the prevalent discourses on modern architecture and modernity in general, have largely influenced the choices of the people of Balat. These discourses present reinforced concrete buildings as modern and the mud-brick ones as primitive, backward, and old-fashioned. They present the urban architecture and life styles of Cairo and Western countries as modern and superior in contrast to vernacular architecture and rural life styles that are portrayed as backward and inferior. Thus, many people in Balat build their houses either of reinforced concrete or of white limestone bricks, explicitly rationalizing this decision in terms of the modernness and newness of these types. Yet, these discourses do not entirely account for their decisions, as there are other factors that contribute to this choice. Moreover, I show that when the inhabitants accept these discourses; they appropriate some of them to serve symbolic needs. What seems to be blind imitation of the people of Cairo turns out to be rational techniques for presenting the self as modern. Imitation is their rational technique to get ahead in a world that associates the rural with backwardness and the urban with modernity. I also show that the architecture of Old Balat that I view as aesthetically impressive was a rational response to certain conditions and needs in the past, many of which no longer exist; the changing circumstances and needs of the people in Balat have produced different architecture that the inhabitants see as suitable to the present time.Furthermore, I argue that contrary to the conceptualization in Western thought of modernity as a condition that is discontinuous with the past and tradition (Harvey, 1989), modernity in Balat reveals that the past and the present, the traditional and the modern are intertwined. In building their houses in New Balat, the inhabitants adopt and appropriate newly introduced architectural elements because they are practical and prestigious, yet, they do not break from their traditions. I show that the inhabitants of Balat perceive modernity as progress which manifests in experiencing and adopting all that is new to them, that which improves and renovates their lives, provided that it does not contradict religion and customs. I investigate how conceptions of modernity in Balat combine cosmopolitan imaginations of economic and cultural progress with local traditions and morality. I show how modernity is not one thing; rather, it is a concept that mediates between the past and future, the local and the universal.I show that though the inhabitants' visions of modernity are informed by several discourses of modernity, they are not passive receivers of these discourses; they often appropriate them to serve their own purposes. The inhabitants of Balat selectively appropriate what they consider modern of the ideas, technologies, lifestyles, and fashion that they get from several sources. I show that though the majority of the informants view progress as change that is mainly positive, they think that it has a few negative aspects. Thus, they resort to religion, as well as their customs and traditions to help them counter the negative aspects of progress. This reveals that modernization in Balat is far from Westernization or Americanization, a fact that challenges widespread assumptions of classic social theory. People in Balat see religion as an important part of their lives, and some of them view the increased religiosity in their community as an aspect of progress that goes hand in hand with the other aspects. I argue that conceptions of modernity in Balat reveal that modernity is not an end-point, to which all peoples seek to reach, but some kind of imaginary that mediates between what is local and what is universal.

This Ph.D. dissertation deals with the photocatalytic degradation of toxic dyes and phenol in aqueous suspension of pure and doped semiconductor metal oxides. The nanoparticles such as Pure WO3, ZnO and NiO were synthesized by precipitation and sol gel while noble metal doped semiconductor oxides were prepared using wet incipient impregnation method. The synthesized nanomaterials were characterized by high-resolution transmission electron microscopy (HRTEM), field emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD). These studies revealed that the synthesized metal oxide nanoparticles were having the range of 7 to 50 nm. The nano-catalysts were applied for removal of carcinogenic organic pollutants (phenol and dyes). The effect of different experimental parameters like calcination temperature, dopants content, laser energy, catalyst concentration, pH and exposure time on photo-catalytic removal of dyes and phenol from aqueous solutions was investigated. The experimental results demonstrated that various parameters mentioned above have strong influence on the photocatalytic degradation process of dyes and phenol. The reaction kinetics for these degradation processes was also discussed.

The rapid population growth, increased global demand for crops, challenges posed by climate change, and heavy reliance on food imports led to many countries facing food insecurity. In hot arid regions, the combination of high ambient temperatures, intense solar irradiation, limited freshwater resources, and lack of fertile soil create a harsh environment for agriculture production. Without sustainable and innovative solutions, cultivation in hot arid regions will become energy-intensive, expensive, and susceptible, if not entirely unattainable. Therefore, this dissertation models, simulates, and analyzes innovative greenhouse technologies for hot arid climates. This dissertation initially evaluates alternative cooling approaches in contrast to conventional refrigeration systems. It presents investigations into the development of a sustainability performance index for comprehensively and accurately comparing different cooling approaches. Twenty-one different cooling cycles and refrigerants were assessed based on three main groups: vapor-compression cycles, thermally-driven cycles, and emerging cycles. Secondly, this research investigates the thermoeconomic performance of four different passive-cooled greenhouse configurations in hot arid climates based on natural ventilation, shading, and buried greenhouse structure. Assessments of thermal performance, water requirements, and detailed economic analyses were conducted. Significant reductions in greenhouse inside temperature and water requirements were computed. However, passive cooling was found to be insufficient to maintain adequate interior temperatures in the summer. Consequently, the third part of this research proposes innovative, resilient, and sustainable integrated greenhouse systems for controlling indoor climate within the cultivation range. The systems utilized advanced renewable energy, cooling, desalination, and storage technologies to sustainably produce cooling, electricity, and irrigation water. Four greenhouse configurations were simulated: closed, shaded, buried, and buried and shaded. The research work revealed significant reductions in cooling demand and water usage and provided a comprehensive life cycle cost analysis of the integrated systems. Finally, the research introduced two novel greenhouse designs optimized for hot arid regions. The first design incorporated four cost-effective and innovative techniques: (1) a fully sunken greenhouse, (2) a fully shaded roof with openings for diffuser lenses, (3) a thermally insulated roof, and (4) a horizontal earth-to-air heat exchanger. Computational modeling (CFD simulations) involved developing a ray-tracing model and a heat transfer model. The results demonstrate that the proposed greenhouse achieves sufficient and well-distributed solar irradiation for plant growth, with a remarkable 85.5% reduction in cooling load and a 67.8% reduction in the lifetime cost of greenhouse cooling. The second innovative design integrated three energy- and cost-efficient techniques: (1) wind tower natural ventilation, (2) a sunken greenhouse structure, and (3) evaporative cooling downdraught. A comprehensive computational model was developed. The results showed efficient ventilation rates and great improvement of the greenhouse's internal microclimate in terms of temperature and relative humidity, reducing interior temperatures by up to 12.9°C from the ambient and increasing humidity by up to 54%. Comparatively, a non-sunken greenhouse faced temperatures up to 8.9°C higher and humidity 39.4% lower.
