Mass spectroscopic and some optical spectroscopic studies ontrace element analysis in solids
This thesis deals with certain aspects of the chemical analysis of solids, viz., the accuracy and precision of measurements and phenomena connected with RF?spark and other discharge processes. Results have been obtained ... -
Geochemistry and geochronology of charecteristics rock types of the dharwar craton
Abstract not available -
X-ray studies on some crystalline complexes between amino acids with ionisable sile chains
The structure, assembly, and function of proteins critically depend upon different types of non?covalent interactions involving amino acid residues. In fact, it is increasingly clear that the extreme subtlety and high ... -
X-ray crystallographic investigations of some analgetic pyrazole derivatives and their crystalline complexes
This thesis reports the single?crystal X?ray diffraction studies on: Antipyrine, a 1:1 complex between antipyrine and salicylic acid (salipyrine), Amidopyrine, Phenylbutazone, and a 2:1 complex between phenylbutazone and ... -
Rb-Sr Geochronology and Trace Elements studies on precambrian granitic rocks of Mysore
Abstract not available -
Investigations in high temperature X-ray crystallography
The field of X?ray single?crystal structure analysis beyond 1000?°C is, at present, highly underdeveloped and hardly explored. Structure determinations, as are routinely performed at room and low temperatures, have not ... -
Balloon-borne far infrared observations of galactic star forming regions
Stars are born predominantly within dense cores of giant molecular clouds having number densities > 10? cm?³. This premise is strongly supported by a wealth of observations showing that the hallmarks of newly formed ... -
Multiscaling in three-dimensional fluid turbulence
Fluid turbulence remains one of the most fascinating unsolved problems in Physics. Different aspects of it have attracted physicists and fluid dynamicists for decades. This thesis studies multiscaling of velocity structure ... -
Star formation in giant extragalactic H II regions
We have compared the B V R H? photometry of a sample of giant extragalactic H?II regions with an evolutionary population synthesis model, after correcting for extinction by dust. The basic diagnostic diagrams used are the ... -
Nuclear quadrupole resonance and relaxation - instrumentation and investigations in group V Trihalides
In the present investigation, we have used nuclear quadrupole resonance (NQR) as a local probe to study the structural and dynamical aspects of Group V trihalides. For this purpose, we have set up a pulsed NQR spectrometer ... -
Study of the Environmental influences on spiral galaxies in clusters
A study is made of some of the environmental factors that affect the dynamics and content of both the gas and stars in cluster spiral galaxies. Two issues form the focus of this thesis: (1) the H?I?deficiency of cluster ...
