    AbstractThrough comparison of three poetic texts describing the career of Rana Raj Singh of Mewar (r. 1652–1680), this paper demonstrates how representations of Aurangzeb could vary dramatically even when they were produced for the same Rajput court. Much of the paper focuses on Rāj-vilās, a vernacular-language work with a lengthy account of conflict between Aurangzeb and the Rajput lords of Marwar and Mewar. Rāj-vilās is also noteworthy for its negative portrayal of the Mughal emperor, whom it castigates as a wicked killer of kin who was duplicitous and vengeful. Sometimes thought to be modern constructions, the criticisms of Aurangzeb found in Rāj-vilās reveal that certain ideas about Indian historical figures have continued to be deployed and repurposed over the centuries. Yet Rajput views during Aurangzeb's lifetime were not uniformly unfavourable, as the Sanskrit texts Rāja-ratnākara and Rāja-praśasti attest. Although these two works resembled Rāj-vilās in covering the reign of Rana Raj Singh and were written at roughly the same time, they cast Aurangzeb in a considerably more positive light. This difference can be attributed to the fluctuating political relationship between the Mughal empire and the Mewar kingdom in the decade between 1677 and 1687, underscoring the need to carefully identify the historical contexts within which representations of Aurangzeb were produced and circulated.</jats:p

    Orthographic influences, vocabulary development and phonological awareness in deaf children who use cochlear implants

    In the current study, we explore the influence of orthographic knowledge on phonological awareness in children with cochlear implants and compare developmental associations to those found for hearing children matched for word reading level or chronological age. We show an influence of orthographic knowledge on syllable and phoneme awareness in deaf and hearing children, but no orthographic effect on rhyme awareness. Nonorthographic rhyme awareness was a significant predictor of reading outcomes for all groups. However, whereas receptive vocabulary knowledge was the most important predictor of word reading variance in the cochlear implant group, rhyme awareness was the only important predictor of word reading variance in the reading level matched hearing group. Both vocabulary and rhyme awareness were equally important in predicting reading in the chronological age-matched hearing group. The data suggest that both deaf and hearing children are influenced by orthography when making phonological judgments, and that phonological awareness and vocabulary are both important for reading developmen

    Genetic variation at the apolipoprotein B gene and associations with coronary heart disease and its factors.

    PhDCoronary heart disease (CED) is the major cause of mortality in Western societies. The main risk factors are plasma lipoprotein concentrations, smoking, blood pressure and family history. The effect of family history implies a genetic contribution to the aetiology, support for which has also come from twin, and other heritability studies. The genetic component of CHID may be studied by the candidate gene approach, whereby the genes of products most likely to be involved in the processes leading to CHD, and in its risk factors, are analysed. The plasma concentration of apolipoprotein (apo) B, the major protein component of low density lipoprotein (LDL), is positively correlated with the risk of developing CHD. In this research, the gene for apo B was analysed for restriction enzyme fragment length polymorphisms (RFLPs). A RFLP is caused by a sequence change in the DNA, and results in length variation in the fragments. RFLPs for apo B have been shown to be associated with CHD and the plasma concentrations of cholesterol, triglycerides and apo B in some population studies. However, other studies have failed to confirm these relations. The work described in this thesis was designed to overcome some of the problems which niay have produced these inconsistencies. A random sample of 300 men, aged 49-65 years, residing in South Wales was studied. RFLPs determined in these individuals were used to generate genotypes and haplotypes (arrangements of specific alleles on a single chromosome). Significant associations were found between some genotypes and some haplotypes with altered concentrations of plasma total cholesterol and LDL cholesterol and with risk of CHD and/or with obesity. Presence of Xbal site (X2X2 genotype) was significantly associated with higher concentrations of plasma LDL cholesterol (p=0.0 19). Absence of Mspl site (M 1) was associated with significantly elevated concentrations of plasma total and LDL cholesterol (p < 0.05) by both the techniques of genotype and haplotype analysis. EcoRl RFLP (absence of the site - El) was the minimum haplotype necessary to detect a significant association with decreased plasma cholesterol J Rajput- Williams Ph. D. Thesis Page 3 concentrations (p < 0.05). Genotypes generated from alleles defined by the Mspl-EcoRl RFLPs were associated with significant variation in serum cholesterol concentration (p < 0.03), showing a stratification of concentration with the highest being associated with loss of the Mspl site and the lowest with the presence of the EcoRl site. Both these RFLPs result in charged aminoacid alterations, and lie close to the LDL receptor binding domain of apo B. The minimum haplotype necessary for detection of apo B with CHD was Xbal-Mspl (p < 0.05). The minimum haplotype associated with obesity was the RFLP pair Pvull-Xbal (p < 0.05). Further examination for mutations of the CpG dinucleotide which may influence cholesterol metabolism was undertaken by screening around the putative LDL receptorbinding domain (RBD) of the apo B gene. One variant was detected for aminoacid residue 3500 (Arg,,,,, 4 Gln) mutation, and two variants for aminoacid residue 3611 which also corresponds to the MspI mutation (Arg,,, ,4 Gln)

    Kingship and Polity on the Himalayan Borderland: Rajput Identity during the Early Colonial Encounter

    No full text
    This book explores the modern transformation of state and society in the Indian Himalaya. Centred on three Rajput-led kingdoms during the transition to British rule (c. 1790-1840) and their interconnected histories, it demonstrates how border making practices engendered a modern reading of 'tradition' that informs communal identities to date. By revising the history of these mountain kings on the basis of extensive archival, textual, and ethnographic research, it offers an alternative to popular and scholarly discourses that grew with the rise of colonial knowledge. This revision ultimately points to the important contribution of borderland spaces to the fabrication of group identities

    Permutations of Rajput identity in the West Himalayas, c. 1790-1840

    No full text
    The sustained interaction of local elites and British administrators in the West Himalayas over the decades that surrounded the early colonial encounter (c. 1790-1840) saw the emergence of a distinctly new understanding of communal identity among the leaders of the region. This eventful period saw the mountain ('Pahari') kingdoms transform from fragmented, autonomous polities on the fringes of the Indian subcontinent to subjects of indigenous (Nepali, Sikh) and, ultimately, foreign (British) empires, and dramatically altered the ways Pahari leaders chose to remember and represent themselves. Using a wide array of sources from different locales in the hills (e.g., oral epics, archival records and local histories), this thesis traces the Pahari elite's transition from a nebulous group of lineage-based leaders to a cohesive unitary milieu modelled after contemporary interpretations of Hindu kingship. This nascent ideal of kingship is shown to have fed into concurrent understandings of Rajput society in the West Himalayas and ultimately to have sustained the alliance between indigenous rulers and British administrators.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

    Metallic nanowires (NWs) are the key performers for future micro/nanodevices. The controlled manoeuvring and integration of such nanoscale entities are essential requirements. Presented is a discussion of a fabrication approach that combines chemical etching and ion beam milling to fabricate metallic NWs. The shape modification of the metallic NWs using ion beam irradiation (bending towards the ion beam side) is investigated. The bending effect of the NWs is observed to be instantaneous and permanent. The ion beam-assisted shape manoeuvre of the metallic structures is studied in the light of ion-induced vacancy formation and reconfiguration of the damaged layers. The manipulation method can be used for fabricating structures of desired shapes and aligning structures at a large scale. The controlled bending method of the metallic NWs also provides an understanding of the strain formation process in nanoscale metals

    Mechanism and performance evaluation of spent-coffee grounds-derived nanocomposite materials for highly efficient photocatalytic degradation of organic pollutant

    The study demonstrates a facile and environmentally friendly method for synthesizing crystalline TiO2 nanoparticles on the surface of hydrochar generated from readily available biomass waste, i.e., spent coffee grounds (SCGs), using a simple sol–gel process. The hydrochar served as a support for TiO2, reducing the rate at which electrons and holes recombine during photocatalysis, thereby facilitating the effective binding of TiO2, enhancing its adsorption capacity, and the convenient separation of the photocatalyst after usage. The materials were tested in the photocatalytic degradation of an organic pollutant, methylene blue (MB) dye. TiO2-hydrochar obtained at 210 ⁰C has the best performance, giving a degradation efficiency of 98.5 % and a mineralization efficiency of 87.1 % in 90 min at neutral pH. Radical trapping experiments showed being the dominant species, followed by . Besides, it showed superior stability with an activity loss of ∼ 9.2 % after five runs. The superior performance of the HCT210 was ascribed to the enhanced interfacial charge transfer kinetics between the TiO2 and hydrochar through bond formation, better light absorption, and the high surface area of the materials. Performance metrics show that synthesized nanocomposites are promising photocatalysts, providing a biomass-assisted method for robust photocatalytic wastewater treatment.Killam TrustsNatural Science and Engineering Research Council (NSERC
