Effect of pre-rotation on cavitation in centrifugal and mixed flow pumps.
It has been theoretically shown that introduction of prerotation at the impeller inlet at design point improves the cavitation performance. A qualitative assessment of this from existing data on centrifugal pump impellers ... -
Investigations on the total synthesis of testorterone and its isomers : A thesis submitted to the I.I.Sc. for the degree of doctor of philosophy.
The thesis entitled "Investigations on the Total Synthesis of Testosterone and its Isomers" is divided into two parts. Part I consists of a comprehensive review of the earlier work done on the chemistry of testosterone and ... -
Some magneto-hydrodynamical problems with an application to astoronomy
Part A: A steady flow with the effect of a controlling field of low conductivity past a rotating cylindrical surface in the case of a dissipative medium and its corresponding flow past a magnetized sphere. Part B: The ... -
Studies in sesquiterpenes.
The thesis “Studies in Sesquiterpenes” is divided into three parts: Part I A brief account of the chemistry of naturally occurring cadinenes, cadinols, and related compounds possessing the cadinane skeleton has been given. ... -
Studies in solid state chemistry : Polymorphic transformations of titanium dioxide
The kinetics and energetics of the transformation of pure anatase (tetragonal) to rutile (tetragonal) have been studied. The rate data fit a first-order rate equation, and the activation energy is approximately 90 kcal·mol?¹. ... -
Studies on the metabolism of riboflavin nucleotide coenzymes in plants
A survey of literature indicates that although the occurrence of B-vitamins in higher plants is well known and also that several plant enzymes require the presence of these for their action, very little work has been carried ... -
Studies on transition from laminar to turbulent flow in a pipe
This thesis describes some investigations on the transition from laminar to turbulent flow in a straight pipe of circu lar cross-section. It is found that Emmons* Theory of transition by the formation and growth of ... -
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 ... -
Synthetic investigations in steroids
Hydrolysis of Agave F Hydrolysis of Agave F gave only sugars, indicating that the polysaccharide was a glucan-fructosan in proportions of 92.7% (calculated) glucose and 7.3% (estimated) fructose. Hydrolysate indicates that ...
