We also aimed the synthesis of a few dibenzoylalkene-type systems such as acenaphthenone-2—ylidene ketones and phenanthrenoneylidene ketones. 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. Acid-Base, Surface electron donating and catalytic properties of binary oxides of Zr with rare earth elements. Preparation method of catalyst , surface area and nature of heat treatment. Adsorption sites and adsorbed species such as oxygen.

Chapter 6 illustrates the study on chitinolytic Streptomyces as antifungal and insecticidal agents. Research theses submitted to Cochin University of Science and Technology Cusat have to pass the plagiarism check before it is approved.

The problem is of interest because arrays of hydrophones are housed inside sonar domes and acoustic plane waves from distant sources are scattered by the dome filled with fresh water and cause deterioration in the performance of the array. The present thesis concentrates largely on sound radiation from floating structure due to moving load. Log In With social network: The synthesis and reactions of simple derivatives of 2 3H – and 3 2H furanones have attracted considerable attention in recent years, primarily in connection with development of routes to antitumor agents that contain this ring as central structural unit.

It is in this context that identifying the deserving for favourable consideration becomes all the more important. On action against any researcher for plagiarism sincethe Sanskrit university authorities came out with a vague reply, saying that research scholars had been directed yhesis re-submit theses if they were found to have been plagiarised.

We propose to develop new and general approaches to the synthesis of furanone ring systems from simple and readily available starting materials since we were interested in examining their rich photochemistry. Thssis the third problem, a high-frequency ray-acoustics method is presented and used to determine the interior pressure field when a plane wave is normally incident on a fluid cylinder embedded in another infinite fluid.

The present thesis concentrates largely on sound radiation from floating structure due to moving load Thesi Many of these investigations remain isolated and further research is needed to bridge the gap in the present knowledge of the field. Catalysis research underpins the science of modern chemical processing and fuel technologies.

Biochemical, Molecular and Functional Thessi. These systems were expected to undergo thermal rearrangement to give furanones and spirofuranones. We also aimed the synthesis of a few dibenzoylalkene-type systems such as acenaphthenone-2—ylidene ketones and phenanthrenoneylidene ketones. These furanone derivatives have immense potential for further investigations.

The problem is of interest because cylindrical arrays of projectors are often used to search for underwater objects.

The tjesis helps in detecting possible plagiarism in a document and generates a report showing similarities with other documents. The present thesis concentrates largely on sound radiation from floating structure due to moving load.

Ph.D THESES : [2697]

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. Catalysis is commercially one of the most important technologies in national economies. New mathematical methods to analytically investigate linear acoustic radiation and scattering from cylindrical bodies and transducer arrays are presented.

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.

The study reveals that the alteration of the 5-HT1A and 5-HT2C receptor function and gene expression in the brain stem, cerebral cortex and hypothalamus play an important role in the sympathetic regulation of cell proliferation, neoplastic transformation and apoptosis.

Although a number of syntheses of furanones were known they were in many cases limited to specific substitution pattems. In the second problem, the errors, when using data-independent, classical, energy and split beam correlation methods, in finding the direction of arrival DOA of a plane acoustic wave, caused by the presence of a solid circular elastic cylindrical stiffener near a linear array of hydrophones, are investigated.

Chapter 1 gives a general introduction to marine actinomycetes; Chapter 2 gives an account on the morphological, biochemical and physiological characterization of marine actinomycetes. Such correlations help to narrow down the search for a good catalyst for a given reaction.

It is shown that the uniform displacement required for generating a source level of dB ref. Selective oxidation catalysts of hydrocarbon feedstocks is the dominant process of converting them to key industrial chemicals, polymers and energy sources. Solid state heterogeneous catalyst materials such as metal oxides and metal particles on ceramic oxide substrates are most common. In the first problem, a method is presented to determine the omni-directional and directional far-field pressures radiated by a cylindrical transducer array in an infinite rigid cylindrical baffle.

Username or Email Address. The work is an 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.

The sectors are used to simulate linear arrays with uniformly distributed normals by using delays. The pressure field is determined by using geometrical and physical acoustics. The universities disclosed data on plagiarism check, done from the academic yearin response to a Right to Information RTI application filed by The Hindu.
