Repeat Purchase Behaviour of Online Customers for Grocery Products
Anecdotal evidence, from industry reports, suggest that consumption patterns in India are increasingly moving away from functional needs to lifestyle considerations. However, there is not much empirical evidence regarding ... -
Online Consumer Behaviour in Low Involvement Products: Cognitive Attributes and Purchase Behaviour
The internet has created fundamental shifts in business and consumer behaviour, akin to the industrial revolution of the 1800s. The internet serves as a ubiquitous and limitless information platform, and is leading to ... -
Predicting Innovation Capability at Team Level: An Exploratory Analysis
Innovation is one of the major concerns for technology-driven organizations. Extensive amount of literature is available on ‘managing innovation’ within organizations at individual level as well as firm level. However, ... -
Behaviour of Granular Materials Under Shock and Blast Loading - A Shock Tube Investigation
Granular and porous materials based protective layers have proven to be very good shock absorbing medium. Although sand material is widely used (as sand bags) till date in civil and military applications as a blast mitigating ... -
HIV-1 Immunogen Design : Envelope Protein Minimization, Stabilization and Glycan Removal
Effective vaccines exist for a number of viral diseases. However, despite much effort, there is no successful vaccine against the Human Immunodeficiency Virus (HIV-1). The envelope glycoprotein (Env) of HIV-1 gp120, the ... -
Design, Development and Performance Study of Microneedle & Micropump-based Transdermal Drug Delivery System
Transdermal drug delivery is the most preferred drug delivery method, due to its high efficiency and less side effects. In conventional transdermal drug delivery, the delivery of macromolecular drugs (ex: Insulin, vaccines ... -
Synthesis and Phase Transformation Studies of Al45Mn55 Ferromagnetic Heusler Alloy
The aim of the present thesis work was to synthesize and explore the phase transformation behavior of a binary Heusler alloy based on AlMn system. The intermetallic phase with the stoichiometry AlMn, which is usually termed ... -
Carbon Starvation Genes Mediate the Cross-talk Between Metabolism and Pathogenesis of Salmonella Typhimurium
