Abstract:
The study on the concept of sanctity of human life is a journey in finding out what
is it said to be “human” in human life. It is an evaluation of the universal concept and
the role it plays in controlling and moulding human conduct and relationships. This
concept is a foundational principle of human rights law and the grundnorm of every legal
system. However, of late, the challenges by way of certain advances in human genetic
research had prompted the need to evaluate the significance and extent of the concept in
human endeavours.
Scientific advances by way of human genetic research promises significant
diagnostic and therapeutic advances but at the same time pose threat to fundamental
notions and assumptions on humanity, hence there is a global concern to derive common
legal standards, Thus the major challenge is to analyse universal principles which can be
a common criteria for evolving legal standards to control certain advances in human
genetic research. Hence the relevance of the study.
The study aims at analysing the content, scope, extent and limitation of the
concept of sanctity of human life. In this attempt it evaluates the extent to which the
concept had been accommodated by legal systems and international human rights
regimes. The problem which had been undertaken in the study is the extent of intrusion
made to the concept by virtue of certain advances in human genetic research.

Abstract:
In the present investigation, an attempt is made to document various episodes of transgression and regression during the late Quaternary period from the study of coastal and shelf sequences extending from the inland across the beach to the shelf domain. Shore parallel beach ridges with alternating swales and occurrence of strand line deposits on the shelf make the northern Kerala coast an ideal natural laboratory for documenting the morpho-dynamic response of the coast to the changing sea level. The objectives of the study are lithographic reconstruction of environments of deposition from the coastal plain and shelf sequences; documentation of episodes of transgression and regression by studying different coastal plain sequences and shelf deposits and evolve a comprehensive picture of late Quaternary coastal evolution and sea level changes along the northern Kerala coast by collating morphological, lithological and geochronological evidences from the coastal plain and shelf sequences. The present study is confined to two shore-normal east-west trending transects, Viz. Punjavi and Onakkunnu, in the northern Kerala coast.

Abstract:
Experimental Neutrino Physics is an active area of research in high energy
physics. The investigation of the properties of this elusive particles
has started since it’s discovery itself. In the standard model of particle
physics, neutrinos are massless, the discovery of neutrino oscillation is the
first evidence that demands the extensions of standard model. It is well
established the existence of three active neutrinos, e, μ and , but recent
experiments like LSND and MiniBooNE has found some anomalies
in their data. These experimental data could not be explained using three
flavour neutrino oscillation physics, but they could explain the anomaly
by adding a fourth type neutrino called sterile neutrinos. The evidences
obtained from these experiments are not yet conclusive. Search for sterile
neutrino is an extensive research area in the field of neutrino physics. The
main work presented in this thesis is a sterile neutrino search at MINOS
(Main Injector Neutrino Oscillation Search) experiment at Fermilab, USA.
MINOS is a two detector experiment at Fermilab, which studies the
neutrinos produced at Fermilab Main Injector particle accelerator. MINOS
Near Detector is situated at 1 km away from the source and the Far
Detector is at Soudan Mine at Minnesota, 735 km away from the neutrino
source. The experiment is built to study neutrino oscillation phenomena
in the atmospheric sector and has made world class measurements on neutrino
oscillation parameters. The MINOS experiment is also capable of
looking for small perturbation in the energy spectra caused by any fourth
type of neutrino and can extract the oscillation parameters.

Abstract:
This thesis entitled seasonal and interannual variability of sea level and associated surface meteorological parameters at cochin.The interesting aspect of studying sea level variability on different time scales can be attributed to the diversity of its applications.Study of tides could perhaps be the oldest branch of physical oceanography.The thesis is presented in seven chapters. The first chapter gives, apart from a general introduction, a survey of literature on sea level variability on different time scales - tidal, seasonal and interannual (geological scales excluded), with particular emphasis on the work carried out in the Indian waters. The second chapter is devoted to the study of observed tides at Cochin on seasonal and interannual time scales using hourly water level data for the period 1988-1993. The third chapter describes the long-term climatology of some important surface oceanographic and meteorological parameters (at Cochin) which are supposed to affect the sea level. The fourth chapter addresses the problem of seasonal forecasting of the meteorological and oceanographic parameters
at Cochin using autoregressive, sinusoidal and exponentially weighted moving average techniques and testing their accuracy with the observed data for the period 1991-1993. The fifth chapter describes the seasonal cycles of sea level and the driving forces at 16 stations along the Indian subcontinent. It also addresses the observed interannual variability of sea level at 15 stations using available multi-annual data sets. The sixth chapter deals with the problem of coastal trapped waves between Cochin and
Beypore off the Kerala coast using sea level and atmospheric pressure data sets for the year 1977. The seventh and the last chapter contains the summary and conclusions and future outlook based on this study.

Abstract:
The present study which is the first of its kind in this region is an
attempt to generate adequate information on the relative abundances, the
seasonal and spatial variations as well as on the source and fate of organic
compounds found associated with the dissolved, particulate and
sedimentary compartments of Chalakudy river system. The study aimed at
investigating variations, the relative proportion of dissolved, particulate and
sedimentary fractions of these materials as well as the pollution extent so as
to be able to comment on the present condition of this river-estuarine
system. This thesis focuses attention on the role of biogeoorganics in modifying the ecological and environmental condition of the dissolved,
particuIate and sediment compartments with their minute variability
subjected to various physical, chemical and biogeochemical processes. A
scheme of study encompassing all these objectives provides the frame work
for the present investigation.

Abstract:
The thesis describes the importance of Indian EEZ, definition and the various factors affecting primary production, general account of phytoplankton and its importance in marine ecosystem etc. In review of literature, general oceanography of Arabian Sea and Bay of Bengal and hydrography of eastern Arabian Sea and western Bay of Bengal. It deals with the distribution patterns of primary production, chlorophyll a, phytoplankton composition and particulate organic carbon in the eastern Arabian Sea and western Bay of Bengal during different seasons. Factors that affect primary productivity are irradiance, temperature, stability of the surface waters, nutrients and zooplankton grazing. The differential biological response of eastern Arabian Sea and western Bay of Bengal to monsoonal regimes. A precise estimation on the primary production of the entire EEZ of India on a regional basis and on a seasonal scale would be the only way to achieve any kind of predictive assessment on the fish stock and their sustainable yield. This study mainly envisages the qualitative and quantitative aspects on the magnitude of phytoplankton standing crop and production of organic carbon and their relationship to environmental characteristics during summer monsoon, Inter monsoon and winter monsoon periods in the east and west coasts of the Indian EEZ.This study revealed that the seasonality exerts a great impact on the biological production in the eastern Arabian Sea and western Bay of Bengal. High biological production may be the reason why most of the fish landings are Concentrated in the west coast of India than east coast. The present data on Phytoplankton production rate and the species composition will provide a meaningful ground for evaluations of exploitable renewable resources of the IndianEEZ

Abstract:
The SST convection relation over tropical ocean and its impact on the South Asian monsoon
is the first part of this thesis. Understanding the complicated relation between SST
and convection is important for better prediction of the variability of the Indian monsoon
in subseasonal, seasonal, interannual, and longer time scales. Improved global
data sets from satellite scatterometer observations of SST, precipitation and refined reanalysis
of global wind fields have made it possible to do a comprehensive study of
the SST convection relation. Interaction of the monsoon and Indian ocean has been
discussed. A coupled feedback process between SST and the Active-Break cycle of the
Asian summer monsoon is a central theme of the thesis. The relation between SST and
convection is very important in the field of numerical modeling of tropical rainfall. It is
well known that models generally do very well simulating rainfall in areas of tropical
convergence zones but are found unable to do satisfactory simulation in the monsoon
areas. Thus in this study we critically examined the different mechanisms of generation
of deep convection over these two distinct regions.The study reported in chapter 3 has shown that SST - convection relation over the
warm pool regions of Indian and west Pacific oceans (monsoon areas) is in such a way
that convection increases with SST in the SST range 26-29 C and for SST higher than
29-30 C convection decreases with increase of SST (it is called Waliser type). It is found that convection is induced in areas with SST gradients in the warm pool areas of
Indian and west Pacific oceans. Once deep convection is initiated in the south of the
warmest region of warm pool, the deep tropospheric heating by the latent heat released
in the convective clouds produces strong low level wind fields (Low level Jet - LLJ)
on the equatorward side of the warm pool and both the convection and wind are found
to grow through a positive feedback process. Thus SST through its gradient acts only
as an initiator of convection. The central region of the warm pool has very small SST
gradients and large values of convection are associated with the cyclonic vorticity of the
LLJ in the atmospheric boundary layer. The conditionally unstable atmosphere in the
tropics is favorable for the production of deep convective clouds.

Abstract:
The present investigation has looked exclusively into the aspect of
the biological phenomenon of settling behaviour by two serious fouling offenders
encountered in the tropical seas mainly on the hulls of ships and stationary structures
in the harbours. The cue to study the behaviour was adopted from the observations
so far made by scientists on the epizoic growth of these organisms on the surfaces
of algal fronds of variegated shape, texture, size etc. The results do indicate that
there are sufficient qualities of bioactive substances produced by plants occupying
the lowest categories in organic evolution and curiously enough these substances
have withstood the test of time.
