Antifungal antibiotics by actinomycetes formation of champamycin - B By Streptomyces Champavatii
Presently, the chemotherapeutic treatment of the widely prevalent fungal infections in humans, animals and plants is far from satisfactory and is in marked contrast to that of bacterial diseases which are controlled successfully ... -
Chemical and biological studies on some natural and synthetic antimicrobial substances
The eventful developments of chemotherapy and the growth in our concepts of the treatment of infective diseases, from Ehrlich to the present day, have been briefly traced, stressing the outstanding practical achievements. ... -
Effect of viscocity and surface tension on the taylor instability of the surface of a cavitation bubble
This thesis is devoted to a consideration of the following problem: A spherical mass of fluid of density ??, viscosity ?? and external radius R is surrounded by a fluid of density ?? and viscosity ??. The fluids are ... -
Investigations in nuclear magnetic resonance
This thesis describes the investigations carried out by the author in nuclear magnetic resonance, a subject which has shown a phenomenal expansion both in experimental techniques and in the range of applications in the ... -
Physico-chemical investigations on rare earth compounds
The work on the hydrolysis of lanthanum ion described in this thesis has revealed the existence of the following hydroxy complexes: LaOH²?, La(OH)??, La?OH³? and La?OH??. The various reactions that occur in this system ... -
Prediction of cavitation damage
A theory which gives a unified picture of (1) the bubble collapse, (ii) the transmission of the collapse pressure, and (iii) the deformation of the material due to the work done by the bubble is proposed, incorporating ... -
Satisfaction and Productivity: A Study of Morale and Team Work in Industry With Respect to Productivity
The present study is an attempt at contributing to our understanding of the problems of satisfaction and productivity in the work groups of industry. The cultural setting of India, in which this investigation has been ... -
Some studies on the hydraulic jump
An air concentration probe has been developed which is ideally suited for measurements in a jump. Complete air concentration studies of the jump have been made for nine Froude numbers from 2.42 to 11.72. It has been ... -
Studies in infrared spectroscopy (Vibrational spectra of molecules and crystals)
Abstract not available -
Studies in laminar boundary layer theory with suction or injection
Chapter I deals with the solution of the full Navier-Stokes equations in the neighbourhood of the leading edge in the presence of suction. We obtain exact solution further downstream on the basis of boundary layer equations ... -
Studies in vitamins A1 and A2
Today we know a great deal about the chemistry of vitamin A and the ill?effects produced in humans and animals through its deficiency. But apart from the function of a small portion of this vitamin in the retina, with ... -
Studies on some fatty acid collectors in the flotation of beach sand minerals of travancore thesis
The beach sands of Travancore contain ilmenite, rutile, monazite, zircon, and garnet among others. The present investigations were undertaken not only with a view to find out the effect of some unsaturated and saturated ... -
Studies on submerged jets
This thesis deals with the studies on submerged jets. In the first part of the thesis, a critical survey of the existing literature has been made with a bibliographical chart on the subject up to date. The second part ... -
Studies on the raman spectra of crystals (PHY)
The Raman spectra of crystals have formed a very fruitful topic of study in the past and such studies, particularly on single crystals in specific orientations, have contributed in a large measure to a better understanding ...
