Colonialism radically transformed the cultures of colonized peoples, often rupturing Indigenous traditions and folklore. Whether creating colonial discourse, promoting orientalist literature, advocating western educational institutions, or through biased media representations, imperial powers systematically oppressed Indigenous and Native peoples. Subjugated communities, however, created, and still form postcolonial discourse from their knowledge systems. This discourse insists on Indigenous and Native culture as central to Indigenous and Native peoples identity. This study examines the postcolonial literature of three groups: Kānaka Maoli, African Americans, and Iraqis. The scope of this dissertation scrutinizes how folklore is employed as resistance in the postcolonial literature of Kānaka Maoli, African Americans, and Iraqis. Folklore as Resistance in Postcolonial Narratives and Cultural Practices: Hawaiian, African American, and Iraqi focuses on the centrality of folklore and cultural histories in the literature of these three groups. Kānaka Maoli emphasize the mo’olelo (hi/story) in their literature. Moʻolelo acts not only as a means to pass down hi/story and culturally significant stories from generation to generation (a genealogy) but also as a mode of resistance to hegemonic and imperial powers. Moʻolelo are not merely legends or myths; instead, they represent ancestral knowledge and connection to Kānaka history. Kānaka Maoli claim and revive ancestral moʻolelo in their literature and cultural performance to illuminate their relationship to place, ʻāina, and their country, the Hawaiian Kingdom. In this work, Dhiffaf al-Shwillay suggests that there are similar tendencies in the literature of Kānaka Maoli, African American, and Iraqis. The folklore and literature of these groups signify the histories of oppression and/or colonization and its aftermath. Al-Shwillay finds that Kānaka Maoli, African American, and Iraqi folklore in literature can be read as resistance to orientalism, oppression, and stereotyping. Following the trajectory of the historical and cultural context for the literary productions of these three communities, she offers analysis and reading of Sage Takehiro, Dana Naone Hall, Haunani-Kay Trask, Brandy Nālani McDougall, Zora Neale Hurston, Badr Shakir al-Sayyab, and Selim Matar. This dissertation concludes by emphasizing the dynamic political and cultural value of moʻolelo and folklore in postcolonial narratives. Al-Shwillay asserts that literature that draws upon folklore and cultural histories transmits evidence of oppressive powers and, crucially, resistance. In this mode of examination of postcolonial literature, al-Shwillay asserts that folklore records the resistance of peoples through their literary production. Folklore carries the knowledge of ancestors, cultural, and history.
In the present work, the thermo-fluid characteristics of a heat exchanger formed of helical coiled tubes immersed in cold water are investigated experimentally. Two types of helical coiled tube are tested, a conventional vertical single helical coiled tube and a new triple vertical helical coiled tube in parallel connection called as meshed coils. The effect of hot water flow rates inside the tubes (ranges from 2.67 to 7.08 l/min), and its inlet temperatures (namely 50, 60, 70 and 80 °C) are investigated. The experimental results show that increasing the flow rate inside the meshed coils leads to decrease the temperature difference between inlet and outlet. An enhancement of heat transfer for meshed coils compared to single coil has been n

of locally made closed loop solar hot water system using a shell and helical coiled tube
heat exchanger as a storage tank. Several measurements are taken include inlet and outlet
temperatures of both collectors and supply water and temperature distribution within the
storage tank. This is beside the water flow rate in both collectors and load cycle. The
main parameters of the system are obtained.
Text Clustering consists of grouping objects of similar categories. The initial centroids influence operation of the system with the potential to become trapped in local optima. The second issue pertains to the impact of a huge number of features on the determination of optimal initial centroids. The problem of dimensionality may be reduced by feature selection. Therefore, Wind Driven Optimization (WDO) was employed as Feature Selection to reduce the unimportant words from the text. In addition, the current study has integrated a novel clustering optimization technique called the WDO (Wasp Swarm Optimization) to effectively determine the most suitable initial centroids. The result showed the new meta-heuristic which is WDO was employed as t

Solar energy, which is abundant as well as widely available in various fields, has the potential to solve the global challenges of long-term freshwater and energy reduction. Researchers are attempting to address the problem in a variety of methods. Due to the fact that solar energy is the foundation for freshwater, several researches have applied it for improving the effectiveness of solar desalination, evaporation, and wastewater treatment. One of the novel methods used for achieving this is known as “hydrogel,” which comes in a variety of forms. As a un

Show MoreA group of amine derivatives [4-aminobenzenesulfonamide derivatives, 2-aminopyridine and 2-aminothiazole] incorporated to α-carbon of diclofenac a well known non-steroidal anti-inflammatory drug (NSAID) to increase bulkiness were designed and synthesized for evaluation as a potential anti-inflammatory agents with expected COX-2 selectivity. In vivo acute anti-inflammatory activity of the selected final compounds (9, 12 and 13) was evaluated in rats using egg-white induced edema model of inflammation in a dose equivalent to (3 mg/Kg) of diclofenac sodium. All tested compounds produced a significant reduction in paw edema with respect to the effect of propylene glycol 50

Show MoreMesoporous silica (MPS) nanoparticle was prepared as carriers for drug delivery systems by sol–gel method from sodium silicate as inexpensive precursor of silica and Cocamidopropyl betaine (CABP) as template. The silica particles were characterized by SEM, TEM, AFM, XRD, and N2adsorption–desorption isotherms. The results show that the MPS particle in the nanorange (40-80 nm ) with average diameter equal to 62.15 nm has rods particle morphology, specific surface area is 1096.122 m2/g, pore volume 0.900 cm3/g, with average pore diameter 2.902 nm, which can serve as efficient carriers for drugs.
