Studies in sulphonamides, sulphones and allied compounds
Studies in Sulphonamides, Sulphones and Allied Compounds Part I – Introduction The present thesis consists of four parts. Introduction under Part I deals in brief with: (1) the history of sulphonamide chemotherapy, (2) the ... -
Studies on sulphone and allied compounds
Introduction The present thesis consists of 5 parts excluding introduction. Introduction deals in brief with: (1) the discovery and the development of sulfone series of drugs, (2) the chemistry of the more important ... -
Microbiological transformations of terpenes and steroids
The thesis entitled "Microbiological transformations of terpenes and steroids" is divided into three main chapters. Chapter I. Microbiological transformations of monoterpenes. This chapter commences with a review of the ... -
A Systems approach for utility assessment of Energy resources in rural Applications
The main objective of the thesis is to develop a systems approach to assess the utilities of alternative energy resources in the context of rural India. The methodology proposed includes those energy resources also which ... -
Radiative interactions in boundary layers
The flow of a compressible, viscous, heat-conducting, radiating gray gas parallel to a gray semi-infinite flat plate is considered. The radiation field is described by using the differential approximation. N, the ratio of ... -
Lectin from mimosa invisa L and its role in rhizobium recognition
Understanding the specificity of the legume-Rhizobium symbiosis may help in improving biological nitrogen fixation in several ways. The causes for this specificity have been studied in only a few systems like clover, ... -
Studies on the mode of inhibition of avian myeloblastosis virus multipulication by cupric isonicotinic acid hydrazide complex
The primary objectives of cancer chemotherapy programs include the screening and evaluation of new chemicals and natural products in experimental systems for their anticancer activity and the recommendation of new anticancer ... -
Conformational studies on polynuc leotides and nucleic acids
After an introduction to the nucleic acids and the conformational studies on them at the monomeric and polymeric levels, the need for investigations on the conformations of 3?-nucleotides is outlined. The significance of ... -
Studies on O-H-O Hydrogen Bonds and conformation of cyclic hexa depsipeptides
The working criteria which have been developed for both O-H...O and N-H...O types of hydrogen bond can be utilised. FIG. 3.5. FLOW CHART OF THE PROGRAM MODULE Read input data: (a) coordinates of the hydrogen bond forming ... -
Motifs in proteins: Disulfide constraints and their applications to protein engineering and peptide modelling
By carrying out a detailed data analysis of 175 PP motifs in proteins, sequence–structure relationships were identified for linking loops 1–5 residues long. Conformational families were recognized in 1-, 2-, 3-, and 4-residue ... -
X-ray crystallagraphic studies on the effect of chirality in amino acids aggregation
A programme of systematic X-ray studies on crystalline complexes involving amino acids and peptides is currently under way in this laboratory. These studies, apart from providing a wealth of information on non-covalent ... -
Theoretical studies on peptide conformation
It is now well established that the biological activities of polypeptides and proteins are intimately connected with their 3-dimensional structures and so the determinations of these provide insight into their mode of ... -
Theoretical studies on the influence of exo-anomeric effect,geometry of sugar linkage on the unperturbed dimensions of polysaccharides
Recently, application of conformational energy calculations in the field of carbohydrates has led to a number of interesting and important results. A few attempts have also been made to compute the unperturbed dimensions ... -
Studies on cation exchange membranes (perpmaplex-C-20)
The investigations described in this thesis have been aimed at contributing to the understanding of equilibrium and non-equilibrium phenomena in ion-exchange membranes. Towards this end, Permaplex C-20 has been chosen as ... -
Physiocochemical investigations on urea-nitrate calcium phosphate system
The experimental results obtained in the present investigation clearly demonstrate that when urea nitrate is ground with tribasic calcium orthophosphate, a reaction takes place in the solid-state even at laboratory temperature ... -
Substitutent and solvent effectson the electronic adsorption spectra of organic molecules, spectroscopy of nonbonded electrons.
The above results show that both the substituent and nitrogen on the N-transition of alkyl iodides are similar to those on the N-alkylamines, and the differences lie in rather three points. This is not surprising because ...
