A Synthesis study of the radio sky at decametre wavelengths.
This thesis describes an all-sky survey made at 34.5 MHz using the low frequency telescope situated at Gauribidanur, near Bangalore (latitude 13.36 12 N). The antenna system is made up of 1000 dipoles arranged in the ... -
Effect of a QSO on its host galaxy
Various arguments and observations have led to a general belief that QSO phenomenon is a form of violent activity in the nuclei of galaxies. It is natural to expect that a powerful source of high energy radiation like a ... -
Fluorescence of Manganese in mixed sulphate glasses and Crystalline medium.
The observed fluorescence decay of Mn²? in potassium sulphate–zinc sulphate glass is of single exponential at low (3 mole %) and high concentrations (12 mole %) of manganese. At higher concentrations of manganese, concentration ... -
NMR spectroscopy of oriented systems: studies at and near magic angle sample spinning
The experiments described in this chapter are important in the context of applications mentioned in section 2.2, viz., (i) analysis of spectra of oriented molecules and (ii) use of liquid crystals for measurement of spinning ... -
Some exact analytic models of time dependent collisionless stellar systems.
This thesis began with the general theme of studying the time-dependent behavior of collisionless self-gravitating systems. It is rather hard to obtain exact, general results by analytical methods (see Mathur 1986 for an ... -
Wide-line and pulsed NMR instrumentation and investigations in certain Hydrazinium metal halides.
This thesis describes the wide-line and pulsed NMR instrumentation and investigations in certain hydrazinium double salts. Proton second moment and proton spin-lattice relaxation time as a function of temperature in the ...
