In Vitro Spectroscopic studies on adenine and membrane binding properties of a cytotoxin, ricin and its constituent polypeptides
Toxins are poisonous substances that in small amounts are quite lethal to organisms, causing them serious injury or death. They include proteins, alkaloids and small molecules produced by plants (phytotoxins), fungus ... -
Structural State of plagioclases and petrogenesis
This study pertains to the determination and analysis of the structural state of plagioclases and to evolve a petrogenetic model for the anorthosites of the Holenarasipur Supracrustal Belt, based on geological relations, ... -
Microwave synthesis and consolidation of advanced ceramics and ceramic composites
Advanced ceramics constitute an important class of materials. There exists today a wide spectrum of electrical, optical, magnetic and structural applications for advanced ceramics. Structural ceramics are employed in ... -
Topics in amine chemistry
The thesis entitled “Topics in Amine Chemistry” is in three parts-A, B and C-as well as an Appendix. Part A describes, in two chapters, the development of an alternative to Gabriel’s amine synthesis based on the chemistry ... -
Utility of microbes in organic synthesis : (i) Selective transformations of acyclic terpenes and (ii) Purification and characteriation of a novel secondary alchohol dehydrogenase
Exploration of microbes in carrying out transformations of natural products has been an important and fascinating method in synthetic organic chemistry. Microbes offer the opportunity to effect selective transformations-a ... -
