Indigeneity and Development: Emerging Contradictions in the Case of the Misings and the Dam on Obonori
(2026) Pegu, Pranab Kumar
The thesis delves into a central question: in a context of agrarian crises and changing political economy, how do Indigenous rural communities engage with development projects that introduce a new structure of accumulation? It explores the relationship between an Indigenous community and a development project, specifically focusing on the under-construction dam on the Obonori River in the Assam- Arunachal Pradesh border. The community faces numerous threats and is acutely aware of the negative impacts associated with the dam. Nevertheless, a significant portion of those affected by its construction has opted to engage in the construction economy that surrounds it in order to sustain their livelihoods. This situation creates a paradoxical relationship with the dam. The thesis seeks to investigate the implications of this involvement, arguing that the conflicting nature of this relationship stems from individuals' struggles for social reproduction. It posits that indigenous populations, often perceived as strong defenders of their land, may not always align with this image. This reveals a complex and dynamic relationship. Hence, the thesis highlights that these intricacies are influenced by a combination of historical capitalist agrarian change, ecological factors, landlessness, joblessness, aspirations, and growing capitalist relationships within the community. Thus, this thesis critically interrogates the dominant narrative that posits Indigenous populations as uniformly opposed to development projects that jeopardise their territories, water resources, and forests. By advancing our understanding of indigeneity, this research emphasises the necessity of contextualising Indigenous experiences within historical, material, and aspirational frameworks. It critiques the prevalent inclination to uphold simplistic and generalised representations of Indigenous communities, which can contribute to the reinforcement of stereotypes that portray these groups as ahistorical and static. Furthermore, the thesis contests reductionist critiques of indigeneity that seek to undermine and delegitimise the claims and agency of Indigenous communities, often without considering the situated nature of claims that are contingent on historical and material contexts.
Studies on Poly (Lactic Acid)/Chitosan based Bioresorbable Composites for Orthopaedic Applications
(2025) Bose, Devleena
The ageing global population, coupled with an increasing number of trauma cases such as accidents and sports injuries, has led to a higher incidence of bone fractures. These fractures require immediate medical attention, often in the form of orthopaedic surgery that involves implanting external or internal fixation devices. The choice of internal fixation devices, such as bone plates, screws, and pins, depends on the severity of the injury and the location of the fracture.
Performance Analysis of Coexistence Based Integrated Communication and Sensing Systems
(2025) Mishra, Aparna
Intelligent transportation systems (ITSs) have emerged as a promising technology to address two major challenges in the road transportation system; road accidents and traffic congestion. ITS require smart vehicles to provide both radar and communication capabilities. This in turn requires a large bandwidth for the effective deployment of both. However, the bandwidth and space constraint at vehicular terminals poses a major challenge for the effective deployment of ITS.
Metal nitrosyl and dinitrosyl complexes as small molecule models for NOD and FNOR
(2025) Ghosh, Riya
The PhD dissertation entitled, “Metal nitrosyl and dinitrosyl complexes as small molecule models for NOD and FNOR” contains five chapters on the topic of mainly the non-heme iron nitrosyls and dinitrosyls and a chromium nitrosyl. The reactivity of these metal nitrosyls with dioxygen (O2) and other reactive oxygen species such as H2O2 have been described in this thesis. Chapter 1 provides a review of recent literature on Fe, Co, Cu, Mn, and Cr nitrosyls, focusing on their reactivity with dioxygen and other reactive oxygen species. The reactivity of the metal nitrosyls with O2 and H2O2 was explored with an aim to understand the mechanism of the nitric oxide dioxygenase (NOD) enzyme, as discussed in chapters 2 to 4. For instance, in chapter 2, the formation of Fe(III)-peroxynitrite intermediate was observed, which decomposes to [FeIV=O] and NO2, leading to the ligand modification. In chapter 3, study of the dioxygen reactivity of two iron-nitrosyls having same ligand framework but different spin-states suggest that the reaction proceeds through different pathways based on M-NO bond strength. In chapter 4, a [CrV=O] intermediate was observed in the reaction of chromium nitrosyl with H2O2. These findings definitely enhance our current understanding of NOD chemistry and make a substantial contribution to the field of metalloenzyme chemistry. In chapter 5, a diiron dinitrosyl complex was synthesized as a model complex of flavodiiron nitric oxide reductase (FNOR). This diiron dinitrosyl complex promotes N–N bond formation leading to transient hyponitrite species through a {Fe(NO)2}9 intermediate to result in the spontaneous release of N2O.
Integrated Biorefinery Approach Towards Production of Sustainable Chemicals and Fuel from Passion Fruit Rind
(2025) Borah, Kakali
Agro-industrial waste represents significant potential for the production of biofuels and value-added chemicals, supporting sustainable waste management and resource sustainability. Passion fruit, a tropical fruit, produces over 60% of its weight as byproducts that are rich in bioactive compounds. This study focuses on investigating the antioxidant properties of yellow passion fruit rind from Northeast India and its prospective application in nutraceuticals, food, and biofuels. Polyphenolic compounds from yellow passion fruit rind (YPFR) were extracted utilising green methods, specifically ultrasound-assisted extraction (UAE) and supercritical fluid extraction (SFE). Each extraction technique was optimised by Response Surface Methodology (RSM) and statistically (p < 0.05) validated substantial correlations between the process variables and extraction efficiency. The extracts from SFE and UAE demonstrated significant concentrations of phenolics, flavonoids, and carotenoids, which contributed to their enhanceddb of xylose which was detoxified to reduce inhibitor concentration and fermented with Pichia (Scheffersomyces) stipitis yielding 9.7 g/L of ethanol. However, the residual biomass obtained following dilute acid pretreatment (PUH-PFR) was treated with 2% NaOH, which removed 92.35% lignin with negligible cellulose loss (7.33%). The enzymatic saccharification of the cellulosic fraction released 67.19 g/L of glucose, which yielded 30.12 g/L of ethanol upon fermentation with Saccharomyces cerevisiae. This approach illustrates the possibilities of utilising passion fruit rind waste for sustainable bioethanol production and environmental sustainability.
