Abstract:
In the present study an attempt has been made to understand the microzooplankton community along the easr coast of India. Most of the earlier studies projected Bay of Bengal as an oligotrophic system where phytoplankton growth is limited by a number of factors among which nutrients are the foremost. Hence it is logical to consider that the most of the primary production in the Bay of Bengal could be contributed by small sized phytoplankton harnessing the available resources, which in turn can be utilized effiency by the microzooplankton only. Hence microzooplankton could play in transferring primary organic carbon to higher tropic levels in this region.

Abstract:
The main objectives of the present investigation were to evaluate the qualitative and quantitative distribution of natural cyanobacterial population and their ecobiological properties along the Cochin estuary and their application in aquaculture systems as a nutritional supplement due to their nutrient-rich biochemical composition and antioxidant potential. This thesis presents a detailed account of the distribution of cyanobacteria in Cochin estuary, an assessment of physico-chemical parameters and the nutrients of the study site, an evaluation of the effect of physico-chemical parameters on cyanobacterial distribution and abundance, isolation, identification and culturing of cyanobacteria, the biochemical composition an productivity of cyanobacteria, and an evaluation of the potential of the selected cyanobacteria as antioxidants against ethanol induced lipid peroxidation. The pH, salinity and nutritional requirements were optimized for low-cost production of the selected cyanobacterial strains. The present study provides an insight into the distribution, abundance, diversity and ecology of cyanobacteria of Cochin estuary. From the results, it is evident that the ecological conditions of Cochin estuary support a rich cyanobacterial growth.

Abstract:
The objectives of the present study are to provide a systematic descriptive documentation of the nature of air pollution of the Cochin industrial agglomeration, estimate the willingness to pay for morbidity reduction due to air pollution in observed and hypothetical markets and to estimate the value of welfare loss in the purchase of property due to reduced air quality. This study is an attempt to examine economic impacts of air pollution on the human health and property values in the industrial capital of Kerala. The process of industrialization in Kerala and the increase in air pollution created damages to human, natural and economic resources in the state. The study documents the extent of air pollution and applied econometric approaches to estimate economic impacts of air pollution on human health and property values. The Important sources of air pollution identified in Cochin are emissions from industries and automobiles.

Abstract:
Ongoing changes in global economic structure along information revolution have produced an environment where knowledge and skills or education and training are considered increasingly valued commodities. This is based on the simple notion that nation’s economic progress is linked to education and training. This idea is embodied in the theory of human capital, according to which the knowledge and skill found in labour represents valuable resources for the market. Thus the important assumptions of the Human capital theory are 910 Human capital is an investment for future (2) More training and education leads to better work skills (3) Educational institutions play a central role in the development of human capital(4) the technological revolution is often cited as the most pressing reason why education and knowledge are becoming valuable economic commodities . The objectives of the present study are, the investment and institutional or structural framework of higher education in Kerala, the higher education market and the strengths and weakness of supply demand conditions , cost and the benefits of higher education in Kerala , impact of recent policy changes in higher education,need for expanding higher education market to solve the grave problem of Un employment on the basis of as systematic manpower planning and the higher education and its association with income and employment.

Abstract:
Comprehensive studies integrating production, consumption and
marketing of ornamental fishes were never conducted in the past in
Kerala and this study is an attempt to highlight the dynamics in a
systematic manner by making a primary empirical study. The
advantages of such an approach are many. First, the study entails
detailed empirical data under a given time frame on various inter linked
economic activities in ornamental fisheries sector. Second, the study
tries to improve upon the previous discipline-bound studies by adopting
an integrated approach. As Kerala has diverse ecological and climatic
conditions, case studies on various ornamental fish production
systems help identifying suitable culture practice for selected
environmental conditions. One of the major conclusions of this study
as explained in the concluding chapter is that although Kerala is
blessed with favourable geographic and climatic conditions needed for
developing ornamental fishery, diverse local conditions and
requirements contain adopting modern methods of enterprise
development.Consumer studies conducted would help to identify the demand of
ornamental fishes and the factors leading to it. Market studies would
help in understanding the forces behind domestic market, which is very
promising, but neglected. Viability studies throw light on the economic
performance of both the production systems and the trading units of
ornamental fishes. Despite the economic significance of ornamental
fisheries industry, its development has been constrained due to various
bio-technical, cultural, socio-economic, organisational and above all,
institutional and policy failures. The outcome of the study would identify
constraints facing the industry and institutional arrangements for
development.

The world demand for fish and fishery products is increasing steadily and it is
generally accepted that it will not be possible to meet the heavy demand with resources
exploited from capture fishery alone. Now aquaculture is well established and fastdeveloping
industry in many countries and is a major focus sector for development.
During recent decades, aquaculture has gained momentum, throughout the world
especially in developing countries. According to Food and Agricultural Oganisation
(FAO, 2000), global aquaculture production was 26.38 tones in 1996 have reached
32.9 million tonnes during 1999. Only marine aquaculture sector has contributed 13.1
million tonnes during 1999.India is a major fish producing country. About one half of lndia’s brackish
water lands are currently being utilized for farming in order to reduce the gap between
supply and demand for fish. Aquaculture has become a major source of livelihood for
people and its role in integrated rural development, generation of employment and
earning foreign exchange, thereby alleviating poverty is being greatly appreciated
around the world.Among the infectious agents, bacteria are becoming the prime causal
organisms for diseases in food fishes and other marine animals. Sindermann, (1970)
reported that bacterial fish pathogen most commonly found among marine fishes is
species of Pseudomonas, Vibrio and Mycobacterium. These can be categorized into
primary pathogens; secondary invaders that may cause systemic disease in
immunocompromised hosts; and normal marine flora which are not pathogenic but
may occur on body surfaces or even within the tissues of the host. I-Iigh density of
animals in hatchery tanks and ponds is conducive to the spread of pathogen and the
aquatic environment with regular application of protein rich feed, is ideal for culturing
bacteria. Bacteria, which are normally present in seawater or on the surface of fish, can
invade and cause pathological effects in fishes, which are injured or subjected to other
environmental stresses.Mycobacteria except parasites are known as nontuberculosis mycobacteria
(NTM), atypical mycobacteria or mycobacteria other than tuberculosis(MO'l'l"). This
group of mycobacteria includes opportunistic pathogens and saprophytes.
Environmental mycobacteria are ubiquitous in distribution and the sources may
include soil, water, warm-blooded as well as cold-blooded animals. Disease caused by
environmental mycobacterial strains in susceptible humans (Goslee & Wolinsky,
1976; Grange, 1987), animals and fishes are increasingly attracting attention. Greatest
importance of environmental mycobacteria is believed to be their role in
immunological priming of humans and animals, thereby modifying their immune
responses to subsequent exposure to pathogenic species.

Abstract:
Biosocial profile can produce variations in Gender-role Orientation of executives.
Biosocial variables are not responsible for the development of Communication
Style except in cases of number of children, dual career family and fathers
occupation. Gender-role orientation is a function of Communication Style.
Executive performance is a function of Communication Style.Gender- role orientation can have a decisive influence on executive performance.
The cumulative effect of Communication Style and gender role orientation can
produce variations in executive performance. Open Communication Style is
predominantly responsible for the creation of a higher level executive
performance than other Communication Styles.

Abstract:
In the present scenario of energy demand overtaking energy supply top priority is given
for energy conservation programs and policies. Most of the process plants are operated
on continuous basis and consumes large quantities of energy. Efficient management of
process system can lead to energy savings, improved process efficiency, lesser operating
and maintenance cost, and greater environmental safety. Reliability and maintainability
of the system are usually considered at the design stage and is dependent on the system
configuration. However, with the growing need for energy conservation, most of the
existing process systems are either modified or are in a state of modification with a view
for improving energy efficiency. Often these modifications result in a change in system
configuration there by affecting the system reliability. It is important that system
modifications for improving energy efficiency should not be at the cost of reliability. Any
new proposal for improving the energy efficiency of the process or equipments should
prove itself to be economically feasible for gaining acceptance for implementation. In
order to arrive at the economic feasibility of the new proposal, the general trend is to
compare the benefits that can be derived over the lifetime as well as the operating and
maintenance costs with the investment to be made. Quite often it happens that the
reliability aspects (or loss due to unavailability) are not taken into consideration. Plant
availability is a critical factor for the economic performance evaluation of any process
plant.The focus of the present work is to study the effect of system modification for improving
energy efficiency on system reliability. A generalized model for the valuation of process
system incorporating reliability is developed, which is used as a tool for the analysis. It
can provide an awareness of the potential performance improvements of the process
system and can be used to arrive at the change in process system value resulting from
system modification. The model also arrives at the pay back of the modified system by
taking reliability aspects also into consideration. It is also used to study the effect of
various operating parameters on system value. The concept of breakeven availability is
introduced and an algorithm for allocation of component reliabilities of the modified
process system based on the breakeven system availability is also developed. The model
was applied to various industrial situations.
