Abstract:
In the present study the preparation and characterisation of rubber ferrite
composites (RFC) containing barium ferrite (BaF) and strontium ferrite (SrF) have
been dealt with. The incorporation of the hard ferrites into natural and nitrile rubber
was carried out according to a specific recipe for various loadings of magnetic
fillers. For this, the ferrite materials namely barium ferrite and strontium ferrite
having the general formula MO6Fe2O3 have been prepared by the conventional
ceramic techniques. After characterisation they were incorporated into the natural
and nitrile rubber matrix by mechanical method. Carbon black was also incorporated at different loading into the rubber ferrite composites to study its
effect on various properties. The cure characteristics, mechanical, dielectric and
magnetic properties of these composites were evaluated. The ac electrical
conductivity of both the ceramic ferrites and rubber ferrite composites were also
calculated using a simple relation. The investigations revealed that the rubber ferrite composites with the
required dielectric and magnetic properties can be obtained by the incorporation of
ferrite fillers into the rubber matrix, without compromising much on the
processability and mechanical properties.

Abstract:
The thesis entitled An Evaluation of Primary Health Care System in Kerala. The present study is intended to examine the working of primary health care system and its impact on the health status of people. The hypothesis tested in the thesis includes,
a. The changes in the health profile require reallocation of resources of primary health care system,
b. Rate of utilization depends on the quality of services provided by primary health centers, and c. There is a significant decline in the operational efficiency of the primary health care system.
The major elements of primary health care stated in the report of AlmaAta International Conference on Primary Health Care (WHO, 1994)” is studied on the basis of the classification of the elements in to three: Preventive, Promotive, and Curative measures. Preventive measures include Maternal and Child Health Care including family Planning. Provision of water and sanitation is reviewed under promotive measures. Curative measures are studied using the
disease profile of the study area. Collection of primary data was done through a sample survey, using pre-tested interview schedule of households of the study area. Multi stage random sampling design was used for selecting the sample. The design of the present study is both descriptive and analytical in nature. As far as the analytical tools are concerned, growth index, percentages, ratios, rates, time series analysis, analysis of variance, chi square test, Z test
were used for analyzing the data. Present study revealed that no one in these areas was covered under any type of health insurance. Conclusion states that considering the present changes in the health profile, traditional pattern of resource allocation should be altered to meet the urgent health care needs of the people. Preventive and promotive measures like health education for
giving awareness among people to change health habits, diet pattern, life style etc. are to be developed. Proper diagnosis and treatment of the disease at the beginning of the stage itself may help to cure majority of disease. For that, Public health policy must ensure the primary health care as enunciated at Alma- Ata international Conference. At the same time Public health is not to be treated as the sole responsibility of the government. Active community participation is an essential means to attain the goals.

Abstract:
Transport of live aquatic organisms which is more than a century old,
perhaps started in the 1870's (Norris et al, 1960). Live fish transportation is
an essential practice in aquaculture particularly in rural areas of developing
countries representing the only means of supplying fry to small scale aqua
culturists (Taylor and Ross, 1988). Very often, large numbers of fry,
fingerlings, juveniles and adult fish are being transported from the hatchery
to fish farms, fish farms to market, processors and consumers. Live fish
command large economic importance in the fresh fish market than dead and
iced fish. Medina Pizzali (2001) observed that live fish in the Kolkata market
was usually sold at higher prices than dead fish and most consumers were
prepared to pay premium prices for live fish, which is considered as the best
guarantee of freshness, quality, and intrinsic characteristics of its flesh (better
texture and delicate flavour) in comparison with fresh/chilled seafood.
Various government and private agencies undertake transport of live fish for
commercial live fish market or for artificial propagation of game

Abstract:
Drainage basins are durable geomorphic features that provide insights into the long term evolution of the landscape. River basin geometry develop response to the nature and distribution of uplift and subsidence, the spatial arrangement of lineaments (faults and joints), the relative resistance of different rock types and to climatically influenced hydrological parameters . For developing a drainage basin evolution history, it is necessary to understand physiography, drainage patterns, geomorphic features and its structural control and erosion status. The present study records evidences for active tectonic activities which were found to be responsible for the present day geomorphic set up of the study area since the Western Ghat evolution. A model was developed to explain the evolution of Chaliar River drainage basin based on detailed interpretation of morphometry and genesis of landforms with special emphasis on tectonic geomorphic indices and markers.

Abstract:
This thesis entitled Exceptions and limitations to intellectual property rights with special reference to patent and copyright law.The study on the limitations and exceptions to copyright and patent was mainly characterized by its diversity and flexibility. The unique feature of limited monopoly appended to intellectual property was always a matter of wide controversy.The historical analysis substantiated this instrumentalist philosophy of intellectual property.the study from a legal space characterized by diversity and flexibility and end up in that legal space being characterized by homogeneity and standardization. The issue of flexibility and restrictiveness in the context of TRIPS is the next challenging task. Before devising flexibility to TST, the question to be answered is whether such a mechanism is desirable in the context of TRIPS.In conclusion it is submitted to reorient the intellectual property framework in the context of the noble public interest objectives.

Abstract:
The thesis entitled “Exploration of Novel Organic Reactions Catalyzed by
Nucleophilic Heterocyclic Carbenes (NHCs)” embodies the results of the
investigations carried out to explore the synthetic potential of N–heterocyclic carbenes
(NHCs) as organocatalyst towards various electrophiles for the synthesis of heterocyclic
and carbocyclic systems. Recent investigations in the generation of homoenolates by the
addition of NHCs to conjugated aldehydes have made it possible to study the reactivity of
this unique three carbon synthon.

Abstract:
Gelation provides a unique medium, which often induces
organization of molecules resulting in the modulation of their
optical, morphological and electronic properties thereby opening a
new world of fascinating materials with interesting physical
properties at nano- meso- and macroscopic levels. Supramolecular
gels based on linear π-systems have attracted much attention due to
their inherent optical and electronic properties which find
application in organic electronics, light harvesting and sensing. They
exhibit reversible properties due to the dynamic nature of noncovalent
forces. As a result, studies on such soft materials are
currently a topic of great interest. Recently, researchers are actively
involved in the development of sensors and stimuli-responsive
materials based on self-assembled π-systems, which are also called
smart materials.
The present thesis is divided into four chapters
