DYUTHI PHD THESIS

The directional responses are compared with the output from an array in an infinite homogenous fluid. The pressure field is determined by using geometrical and physical acoustics. They also serve as useful synthetic building blocks for lactones and furans and are the precursors of a wide variety of biologically important heterocyclic systems. Log In With social network: Co-existence of dilferent types of ions or structures. Such correlations help to narrow down the search for a good catalyst for a given reaction. The investigation of mechanisms involving different models of hepatocyte proliferation contributes to our knowledge about serotonergic regulation of cell growth, apoptosis and carcinogenesis of liver.

Anu Pavithran, V; Dr. The development of altemative strategies for the preparation of these heterocycles is therefore of considerable importance or continues to be a challenge. Preparation method of catalyst , surface area and nature of heat treatment. The thesis is comprised of seven chapters. Summary and Conclusion of the study is presented in Chapter 7, followed by References and Appendices.

The researcher recommends a plan of action with long term perspective and suggests appropriate strategies for the export development of the traditional and nontraditional agricultural items. Numerical results are presented for a circular array with 32 hydrophones and 12 hydrophones in each sector. These systems were expected to undergo thermal rearrangement to give furanones and spirofuranones.

Or enter first few letters: The solution to the Helmholtz equation and the displacement continuity condition at the interface between the array and the surrounding water are used to determine the pressure.

Although a number of syntheses of furanones were known they were in many cases limited to specific substitution thrsis. Many of these investigations remain isolated and further research is needed to bridge the gap in the present knowledge of the field.

The directional responses, to the plane wave, of sectors of a circular array of uniformly distributed hydrophones in the embedded cylinder are then computed. Summary and Conclusion of the study is presented in Chapter 7, followed by References and Appendices. New mathematical methods to analytically investigate linear acoustic radiation and scattering from cylindrical bodies and transducer arrays are presented.

Eventhough generic level identification is possible by traditional phenotypic methods, species level identification necessitate a polyphasic approach including both phenotypic and genotypic characterization.

Now showing items of Next Page. Also these systems can be categorised as quinonemethides which are valuable synthetic intermediates. Anuradha, P K; Dr. Hence we propose to synthesis a few phenanthro-2 3H -furanones to study the effect of a radical stabilising group at 3-position of furanone ring on photolysis. Three problems of interest involving cylinders in an infinite fluid are studied. To explore the tripletmediated transformations of 2 3H -furanones in polar and nonpolar solvents a few 3,3-bis 4-chlorophenyl aryl-3H-furanones and 3,3-di p-tolyl aryl- 3H-furanones were synthesised from the corresponding dibenzoylstyrene precursors by neat thermolysis.

The regulatory role of 5-HT1A and 5-HT2C receptor during neoplastic transformation and apoptosis could lead to possible therapeutic intervention in the treatment of cancers and have immense clinical importance. The protocol developed by us employs readily available phenanthrenequinone and various 4-substituted acetophenones as starting materials and provides easy access to the required 3 2H -furanone targets. These furanone derivatives have immense potential for further investigations.

Solid state heterogeneous catalyst materials such as metal oxides and metal particles on ceramic oxide substrates are most common. Comments Our site Facebook Disqus. Our aim was to study the nature of intermediates involved in these transformations. Hence we propose to synthesis a few phenanthro-2 3H -furanones to study the effect of a radical stabilising group at 3-position of furanone ring on photolysis. Chapter 1 gives a general introduction to marine actinomycetes; Chapter 2 gives an account on the morphological, biochemical and physiological characterization of marine actinomycetes.

Taken together, these unleash grave demands on formulating equitable standards. The work is thesos attempt to understand the role of 5-HT, 5-HT1A and 5-HT2C receptors in the regulation of liver cell proliferation using in vivo and in vitro models. Some of the thesiz photoreaction pathways of unsaturated lactones include decarbonylation, solvent addition to double bonds, decarboxylation, migration of aryl substituents and dimerisation.

In-spite of the phenomenal increase since independence in the number of institutions imparting education and the number of beneficiaries, India being the second largest nation in terms of population of the young finds its resources spread thin in meeting the demand for education.

Although a number of syntheses of furanones were known they were in many cases limited to specific substitution pattems. The present study explored thesid potential of marine actinomycetes especially Streptomycetes as a promising source of bioactive molecules for application in aquaculture and dyutthi industry. The directional responses, to the plane wave, of sectors of a circular array of uniformly distributed hydrophones in the embedded cylinder are then computed.
