A syntactic model for representing the behaviour of mechanical artefacts in product models
Product models are being proposed as information models to drive the entire product lifecycle. CAD models that drive the product development cycle presently are primarily a repository of shape information and, therefore, ... -
Fracture Processes in Sustainable Fibrous Cementitious Composites: Insights from Statistical Mechanics and Natural Time Analysis
In recent years, there has been a growing demand in the construction industry for slender, durable, and high performance structural elements. This has led to the development of an advanced cementitious composite material ... -
Understanding Strain Rate Response of Geomaterials through Orthogonal Cutting Experiments
Cutting is a complex, large deformation process used for the removal of material during various engineering operations. In geomaterials, such as soils and rocks, the mechanism of cutting is encountered during operations ... -
Passive Interfacial Evaporation-based Thermal Desalination Systems
Desalination offers a promising solution to the global water shortage by utilizing the vast resource of seawater. With 26% of the world’s population lacking access to potable water currently, there is a growing need to ... -
Behavioural and neural signatures of interactions between conflicting emotion and reward
Reward-related events seldom occur in isolation in our everyday lives — a component of emotion processing remains intertwined in many cases. For instance, individuals often work under hostile conditions for higher pay or ... -
Development of Perception Systems to Enhance Robustness for Robotic Applications
Robotic systems are composed of interconnected modules such as planning, control, and perception, where inaccuracies in the perception module can trigger cascading failures throughout the entire pipeline. To achieve reliable ... -
Studies on the metabolism of aminophenols
Certain o-aminophenols like 3-hydroxykynurenine and 3-hydroxyanthranilic acid are known to be precursors of nicotinic acid as well as of certain phenoxazinone antibiotics and insect pigments. The metabolism of 3-hydroxyanthranilic ... -
Studies on the action of nbromsuccinimide on Hemoglobin and lysozyne
The above detailed account of the role of various groups in enzyme function amply illustrates the approaches to the study of the structural basis of enzyme action. One particular fact emerges out of the present account. ... -
Studies on the amino-acid composition and nutritive value of some Indian food stuffs
The thesis entitled “Studies on the Amino Acid Composition and Nutritive Value of Some Indian Foodstuffs” presents the following pieces of research work carried out by the candidate: Standardisation of the microbiological ... -
Metabolism of naphthalene and methylnaphthalenes in Pseudomonas putida : Elucidation of catabolic pathways and purification and properties of 1,2-Dihydroxynaphthalene dioxygenase
I. Polycyclic aromatic hydrocarbons (PAHs), which include naphthalene and alkyl-substituted naphthalenes, are universal products of combustion of organic matter. The mutagenic and carcinogenic nature of several PAHs makes ... -
Studies on the antibiotic principles of garcinia morella and allium sativum
Part I Section A: The preparation, purification and properties of morellin, the active principle of Garcinia morella, have been described. By chromatographic technique on silica gel columns three distinct pigments viz., ... -
Some aspects of the metabolism of mandelic acid by Aspergillus Niger
The two first enzymes in the pathway for the metabolism of mandelic acid by Aspergillus niger, namely D(-)-mandelate oxidase and L(+)-mandelate oxidase, which respectively catalyze the oxidation of the two enantiomers of ... -
some studies on the mean Meriodional circulation droughts
It has been observed that during a break in the Indian southwest monsoon, the middle latitude circulation enters low index regime or Rossby regime. These Rossby waves are found to propagate southwards even up to Indian ... -
Structure of shock waves in a partially ionized gas. Ph.D. Thesis
A unified picture of the structure of steady one-dimensional shock waves in a partially ionized gas in the absence of externally applied electric or magnetic field is presented. The investigation is based on a two-temperature, ...
