Abstract:
This thesis Entitled Post-Environmental Evaluation of The Rajjaprabha Dam In Thailand.
This post evaluation of environmental consequences of Rajjaprabha dam IS conducted ten years after its commencement. The Rajjaprabha dam project was planned and implemented as a multipurpose
project, mainly for hydropower production, flood protection, fisheries, recreation and irrigation. The project includes the dam and reservoir with a 240 MW hydropower plant located about 90 km upstream from Surat Thani province, and irrigation systems covering the coastal plain in Surat Thani. The upstream storage reservoir (with about 5,639 mcm storage) and the hydropower plant had already been implemented. The first phase of irrigation system covers an area of 23,100 hectares. The second phase is envisaged to cover about 50,000 hectares.
This study was conducted with the following objectives: (I) to assess all existing environmental resources and their values with the help of input-output analysis (2) to findout the beneficial impacts of the project (3) to evaluate the actual positive effects vis-a-vis the estimated effects before the project was implemented and (4) to identify all significant changes in relatives to the impacts previously assessed.
The study area includes the Phum Duang river basin of about 4,668 km2 (placed on the areas that are upstream and downstream to the damsite), The duration of study is limited to 10 years after the dam has become operational i.e. from 1987-1997.
The results of the study reveal that there is no significant changes in climatic and ground water resources, with respect to the study area inspte of the fact that the physical and chemical properties of the soil have slightly changed. Sedimentation in the reservoir does not have much effect on the function of the dam.

Abstract:
The present study is an attempt to understand the link between natural resource degradation and poverty among people dependent on these resources. This is done by examining the impact of depletion of marine resources on the livelihood and socio-economic condition of the small-scale marine fishery community in South Kerala. In Kerala, nearly ten lakh fisherfolk depend on the marine fishery resources for their livelihood. The overall level of education of the small-scale fishing community is lower than that of the State’s rural population. Almost all the households surveyed, is one way or other, depend on fishery resources for livelihood. Low levels percapita income and high levels of inequality imply the existence of a large proportion of poor people in the community who are vulnerable to external shocks. The study reveals that poverty was comparatively higher among households with no fishing assets, with only one earner, with more than two children, and depending entirely on pensions/remittances. The study has not provided any evidence to show that poverty in the community is the result of depletion of marine resources.

Abstract:
The Power Of Taxation Under The lndian Constitution, the subject of the present thesis has a
wide ambit covering the entire federal field end deep constitutional significance traversing many of the principles like pith and substance, colourability, severebility etc. However, considerations of time, space and areas already investigated have indicated that the present study may be confined to the fundamental constitutional limitations end the federal problem. Thus the effect of fundamental rights, the commerce clause, immunity of instrumentalitis and the principle limiting the power of legislative delegation on the power of taxation has been studied. The distribution of taxes between the Union and units of the Indian federation leans so much over to the former and that part of this study has been directed to discover what devices can help the units to gain economic viability

Abstract:
Managers are central to any fuction in a complex and developed society. Their talents are reckoned to be cardinal in developed economies and a basic yearning of all developing economies.In order to survive and produce results in a turbulent and transient environment, the task is to understand the nature of factors contributing to managerial effectiveness. This study is an attempt towards this core issue of the present from a different perspective. This study tries to focus attention on a group of managers functioning in the field of banking, a core sector in the country's economy. The gamut of economic activities in Kerala being predominantly service-oriented, importance of commercial banking is almost indisputable. Though economists would argue that the disproportionate development of service sector is anomalous when viewed against the hazy scenarios in the primary and secondary sectors of the state’s economy, the extent and pace of growth in the banking sector has had its dole meted out by ambitious and productive managers fiinctioning in the field. Researcher’s attempt here is to thresh the grain and chaff among bank managers in terms of their effectiveness and to account for the variations in the light of their ability to affect the thoughts and actions of their subordinates. To put it succinctly, the attempt herein is to explain the effectiveness of bank managers in the light of their ‘Power Profile’ taken to be comprising Power Differentials, Power Bases, their Visibility and Credibility in the organisation and, the Power Styles typically used by them for influencing subordinates.

Abstract:
In spite of the far longed practices of technical analysis by many
participants in Indian stock market, none have arrived at the exact position of
technical analysis as a tool for foretelling share prices. There is no evidence
supporting that one has established its definite role in predicting the behaviour of
share price and also to see the extent of validity (how far reliable) of technical tools
in Indian stock market. The problem is the vacuum in the arena of securities market
analysis where an unrecognised tool is practised, i.e., whether to hold on to technical
analysis or to drop it. Again, as already stated in this chapter, its validity need not
continue forever. It may become futile as happened in developed markets.
Continuous practice of a tool, which is valid only during discontinuous times is also
an error. The efficacy of different market phenomena in terms of their ability to
foretell the extent and direction of the price movements and reliability thereof
remain as not yet proved in. This requires further study in this area so that this
controversy may be settled. A solution to the problem requires enquiring and
establishing the applicability of technical analysis, if any, there is in the Indian stock
market. The study has the following two broad objectives for the purpose of
confirming the applicability, if any, of technical analysis in the Indian stock market.
The first objective is to ascertain the current validity of ‘traditional holding with
respect to patterns’ and the second objective is to ascertain the ‘consistent
superiority’, if any, of technical indicators over non-signal strategies in return
generation. The study analyses the five patterns, which are widely known and
commonly found in publications. They are: (1) Symmetrical Triangles, (2) Rising
Wedges, (3) Falling Wedges, (4) Head and Shoulders Top and (5) Head and
Shoulders Bottom.

Abstract:
Post purchase behaviour is the response of a consumer after purchasing a product.
This is influenced by attitudes, product and dealer related factors, subjective norms
and perceived behavioural control.Realising the significance of these factors on the
marketing strategies of a product, the present research is undertaken to study the
influence of these factors on the post purchase behaviour of consumers of pre owned
cars in Kerala. This work also identifies the profile of pre-owned car consumers of
Kerala. The specific objectives are a) To identify the demographic profile of
consumers who purchased pre owned cars b) To study the relationship between
product related factors and consumer attitude towards the purchase of pre owned cars
c) to study the relationship between dealer related factors and consumer attitude
towards the purchase of pre owned cars d) To analyse the relationship between
consumers’ attitude and post purchase behavior e) To analyse the relationship
between subjective norms and post purchase behavior and f) To analyse the
relationship between perceived behavioural control and post purchase behaviour
The study is confined to consumers who own and use pre owned cars purchased from
authorised dealers in Kerala. The study was based on field research and made use of
both primary and secondary data. Primary data were collected from 750 respondents
distributed in five districts of Kerala. The study found that product and dealer related
factors plays a vital role in shaping attitude of consumers towards pre owned cars
which in turn influence the repurchase intention and decision to recommend to friends
and relatives. Repurchase intention of pre owned car consumers are significantly
influenced by the subjective norms and perceived behavioural control. This study
would help marketers to understand the post purchase behaviour of pre owned car
consumers and formulate the marketing strategies accordingly.

Abstract:
There is an increasing demand for renewable energies due to the limited availability of fossil and nuclear fuels and due to growing environmental problems. Photovoltaic (PV) energy conversion has the potential to contribute significantly to the electrical energy generation in the future. Currently, the cost for photovoltaic systems is one of the main obstacles preventing production and application on a large scale. The photovoltaic research is now focused on the development of materials that will allow mass production without compromising on the conversion efficiencies. Among important selection criteria of PV material and in particular for thin films, are a suitable band gap, high absorption coefficient and reproducible deposition processes capable of large-volume and low cost production. The chalcopyrite semiconductor thin films such as Copper indium selenide and Copper indium sulphide are the materials that are being intensively investigated for lowering the cost of solar cells. Conversion efficiencies of 19 % have been reported for laboratory scale solar cell based on CuInSe2 and its alloys.
The main objective of this thesis work is to optimise the growth conditions of materials suitable for the fabrication of solar cell, employing cost effective techniques. A typical heterojunction thin film solar cell consists of an absorber layer, buffer layer and transparent conducting contacts. The most appropriate techniques have been used for depositing these different layers, viz; chemical bath deposition for the window layer, flash evaporation and two-stage process for the absorber layer, and RF magnetron sputtering for the transparent conducting layer. Low cost experimental setups were fabricated for selenisation and sulphurisation experiments, and the magnetron gun for the RF sputtering was indigenously fabricated. The films thus grown were characterised using different tools. A powder X-ray diffractometer was used to analyse the crystalline nature of the films. The energy dispersive X-ray analysis (EDX) and scanning electron microscopy
i
(SEM) were used for evaluating the composition and morphology of the films. Optical properties were investigated using the UV-Vis-NIR spectrophotometer by recording the transmission/absorption spectra. The electrical properties were studied using the two probe and four probe electrical measurements. Nature of conductivity of the films was determined by thermoprobe and thermopower measurements. The deposition conditions and the process parameters were optimised based on these characterisations.

Abstract:
The objectives of the proposed work are preparation of ceramic nickel zinc ferrite belonging to the series Ni1-XZnXFe2O4 with x varying from 0 to 1in steps of 0.2, structrural, magnetic and electrical characterization of Ni1-XZnXFe2O4, preparation and evaluation of Cure characteristics of Rubber Ferrite Composites (RFCs), magnetic characterization of RFCs using vibrating sample magnetometer (VSM), electrical characterization of RFCs and estimation of magnetostriction constant form HL parameters. The study deals with the structural and magnetic properties of ceramic fillers, variation of coercivity with composition and the variation of magnetization for different filler loadings are compared and correlated. The dielectric properties of ceramic Ni1-XZnXFe2O4 and rubber ferrite composites containing Ni1-XZnXFe2O4 were evaluated and the ac electrical conductivity (ac) of ceramic as well as composite samples can be calculated by using a simple relationship of the form ac = 2f tan 0r, with the data available from dielectric measurements. The results suggest that the ac electrical conductivity is directly proportional to the frequency

Abstract:
Present work deals with the Preparation and characterization of high-k aluminum oxide thin films by atomic layer deposition for gate dielectric applications.The ever-increasing demand for functionality and speed for semiconductor applications requires enhanced performance, which is achieved by the continuous miniaturization of CMOS dimensions. Because of this miniaturization, several parameters, such as the dielectric thickness, come within reach of their physical limit. As the required oxide thickness approaches the sub- l nm range, SiO 2 become unsuitable as a gate dielectric because its limited physical thickness results in excessive leakage current through the gate stack, affecting the long-term reliability of the device. This leakage issue is solved in the 45 mn technology node by the integration of high-k based gate dielectrics, as their higher k-value allows a physically thicker layer while targeting the same capacitance and Equivalent Oxide Thickness (EOT). Moreover, Intel announced that Atomic Layer Deposition (ALD) would be applied to grow these materials on the Si substrate. ALD is based on the sequential use of self-limiting surface reactions of a metallic and oxidizing precursor. This self-limiting feature allows control of material growth and properties at the atomic level, which makes ALD well-suited for the deposition of highly uniform and conformal layers in CMOS devices, even if these have challenging 3D topologies with high aspect-ratios.
ALD has currently acquired the status of state-of-the-art and most preferred deposition technique, for producing nano layers of various materials of technological importance. This technique can be adapted to different situations where precision in thickness and perfection in structures are required, especially in the microelectronic scenario.

Abstract:
Use of short fibers as reinforcing fillers in rubber composites is on an
increasing trend. They are popular due to the possibility of obtaining anisotropic
properties, ease of processing and economy. In the preparation of these composites
short fibers are incorporated on two roll mixing mills or in internal mixers. This is a
high energy intensive time consuming process. This calls for developing less energy
intensive and less time consuming processes for incorporation and distribution of
short fibers in the rubber matrix. One method for this is to incorporate fibers in the
latex stage. The present study is primarily to optimize the preparation of short
fiber- natural rubber composite by latex stage compounding and to evaluate the
resulting composites in terms of mechanical, dynamic mechanical and thermal
properties. A synthetic fiber (Nylon) and a natural fiber (Coir) are used to evaluate
the advantages of the processing through latex stage. To extract the full reinforcing
potential of the coir fibers the macro fibers are converted to micro fibers through
chemical and mechanical means.
The thesis is presented in 7 chapters
