Queen Succession in the Primitively Eusocial Wasp Ropalidia Marginata
(2018-01-04)Social insects are the most dominant terrestrial fauna for the last 50 million years. This tremendous ecological success is accompanied by the fact that sociality has evolved multiple times independently and achieved highest ... -
Queens And Their Succerssors : The Story Of Power In The Primitively Eusocial Wasp Ropalidia Marginata
(2009-04-30)Ropalidia marginata is characterized as a primitively eusocial wasp due to the absence of morphological differentiation between the queen and worker castes. Unlike other primitively eusocial wasps, however, the queen in ... -
Quest for New Chalcopyrite Semiconductors for Photodetector Applications
Photodetectors are widely used as image sensors, in optical communication, remote sensing etc. IR detectors find widespread applications in night vision cameras and medical diagnostics. In this thesis a new chalcopyrite ... -
Quinone studies
CHAPTER I First chapter contains a brief review on the oxidation-reduction potentials of quinones. Various factors like resonance energy, substituents, solvents and pH of the medium that influence the oxidation-reduction ... -
Racemases in Salmonella : Insights into the Dexterity of the Pathogen
(2018-02-27)Chapter -I Introduction Salmonella is a pathogen well-known for its ability to infect a wide variety of hosts and causes disease ranging from mild gastroenteritis to typhoid fever. During infection, it is exposed to a ... -
Radiative effects of aerosols over land and ocean
The last two centuries have witnessed tremendous growth on all fronts (especially industrial) compared to what had occurred in the past thousands of years. This growth brought along, in addition to the awareness of safety ... -
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 ... -
Radical and Lewis Acid Mediated Syntheses of Panaginsene, Indole-Fused Azabicyclo[3.3.1]Nonane and Davanoids
The thesis contains radical and Lewis acid-mediated syntheses of panaginsene, indole-fused azabicyclo[3.3.1]nonanes, and davanoids. The thesis includes three chapters; chapter-I contains the total synthesis of panaginsene, ... -
A Radio Study Of Gas Loss Processes In Nearby Galaxies
(2008-10-17)The work in this thesis involves detailed multi-frequency radio continuum (from 325 MHz to 15 GHz) and Hi spectroscopic studies of a few represent tative nearby galaxies which are experiencing gas-loss from their disks ... -
Radiotracer and soliometric investigations
The thesis consists of two parts: the first part deals with a radiotracer study of the source of sulphur pick?up in manganese deposits obtained from a manganous sulphate (0.2 M) – ammonium sulphate (1.0 M) bath containing ... -
Rainbow Colouring and Some Dimensional Problems in Graph Theory
(2018-04-05)This thesis touches three different topics in graph theory, namely, rainbow colouring, product dimension and boxicity. Rainbow colouring An edge colouring of a graph is called a rainbow colouring, if every pair of vertices ... -
Rainbow Connection Number Of Graph Power And Graph Products
(2014-09-09)The minimum number of colors required to color the edges of a graph so that any two distinct vertices are connected by at least one path in which no two edges are colored the same is called its rainbow connection number. ... -
Raman and Brillouin Nonlinearities in High Power Fiber Lasers: Novel Effects and Applications
High power fiber lasers due to their immense utility in both industry and research divisions, have seen a dramatic level of power scaling in the last two decades. This is due to the superior beam quality, thermal handling ... -
Raman and infrared study of vibrational and rotational relaxations
Our data on the area-ratio of the split components of the Ag Raman line in potash alum show a clear departure from the Boltzmann distribution at temperatures below 150 K. Modification of the phonon-induced transition rates ... -
Raman and IR Spectroscopic Studies of Bacteria, Endotoxin, DNA and Lipoproteins
In the past few decades, vibrational spectroscopy has emerged as a powerful technique in biomedical research. Raman and IR spectroscopy, which are based on signatures specific to molecular vibrations, has found a wide ...
