Some experimental investigations of the fine scale structure of turbulence
In this thesis some properties of the fine scale structure have been investigated experimentally. The terminology “fine scale structure” means, in the author's opinion, small eddies which are different from energy?containing ... -
Nonequilibrium wake flows
In order to study the memory of the larger eddies in turbulent shear flow, experiments have been conducted on plane turbulent wakes subjected to external pressure gradients. In some of these experiments the pressure gradient ... -
Design of a thermostable pan-sarbecovirus vaccine
Coronaviruses (CoVs) are a global health threat due to their potential for widespread transmission including in humans. Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the etiological agent responsible for ... -
Quantization using Side-Information for Distributed Optimization: Theory and Practice
This thesis aims to systematically study the role of side-information for different problems arising in distributed quantization and optimization. In the first part of the thesis, we study a universal version of the ... -
Time-Series Prediction for Intent Aware Robot Learning
The study of time-series prediction and intent modeling forms a fundamental component of intelligent and adaptive systems in robotics and human–machine interaction. Accurately modeling temporal dependencies and anticipating ... -
Structure-Activity Correlation Studies of Mononuclear Mn(I) Carbonyl Complexes as Photoactive Carbon Monoxide Releasing Molecules
Carbon monoxide (CO) is a recognized gasotransmitter, similar to nitric oxide (NO) and hydrogen sulphide (H₂S). It is endogenously produced in mammals as a result of haem catabolism, catalysed by haem oxygenase enzymes. ... -
Studies on the reactivity of dicopper (II) tetraacetate dihydrate towards N-donor ligands
Abstract not available -
Combustion synthesis and properties of fine particle oxide materials: studies on Ferrites
Synthesis of oxide materials with desired structure and properties is of prime importance in Solid State Chemistry and Materials Science. Since the discovery of superconductivity in oxide ceramics, there has been renewed ... -
Overcoming Processing Constraints in Organic Electronics: Crosslinking Strategies and Ultra-Thin Film Integration
The evolution of modern electronics has been dominated by Si-based technologies for many years, as they have enabled reliable, powerful, and compact devices. While the silicon-based technologies are powerful, they face ... -
Studies of Arabinomannan Glycans in Carbohydrate-Protein Interactions and Thermotropic Liquid Crystal Behavior
This thesis investigates the structural and functional roles of multivalency and self-assembly of arabinomannan-based glycoconjugates and glycolipids. Synthetic arabinomannan oligosaccharides were prepared, with defined ... -
Characterizing the role of claudins in C. elegans neurons
Cell adhesion molecules (CAMs) play important roles in neurons, contributing to nervous system development, synapse formation and plasticity. A subset of CAMs, Claudins, known for their roles at tight junctions, remain ... -
Synthesis, spectra and structure of hydrazinium metal chloride and thiocynate complexes.
Coordination compounds containing positively charged ligands occur rather seldom in marked contrast with neutral and negatively charged ligands. The presence of positive charge in the vicinity of a potential donor atom in ... -
Contributions to the chemistry of phosphorus fluorine compounds and a few complex fluorides
The thesis incorporates the results of the investigations on (1) Oxidative reactions of sulphur trioxide, iodine monochloride and nitryl chloride with phosphorus trifluoride and thiophosphoryl fluoride, (2) Reactions of ... -
Studies on fine particle alpha alumina and related oxides prepared by a novel combustion process
Aluminous oxides form one of the major and most important classes among oxide ceramics. Their technological applications as refractories, abrasives, cutting tools (?-Al?O?, MgAl?O?), high alumina cement (CaAl?O?), catalysts ... -
Complex plane and DC polarographic studies of lead (11) ethanolamine (mono-D1 and TR1-) systems
A detailed investigation on the polarographic (d.c. and complex plane) behavior of lead ion in sodium perchlorate, potassium nitrate, potassium chloride, ethanolammonium (mono-, di-, and tri-) perchlorates and the respective ... -
35 CI NQR instrumentation and investigation of some chloropyridinols and chloropyridine-N-Oxides
The detection of quadrupole resonance absorption requires application of a radio frequency magnetic field H? of suitable frequency. The rf field H? should be such that ?H?T?T? ? 1 to avoid saturation, but not be so small ... -
Kinetics and mechanism of the transient behaviour of magnesium anodes
The main objective of the present investigation is to study the mechanism of delayed dissolution of magnesium anodes during discharge of magnesium dry cells. A supplementary part of the work is devoted to the development ...
