Abstract:
India is on the threshold of industrial and economic
development. The growth would be retarded if harmonious
employer-employee relations are not maintained. 'Wages'
plays a fundamental role in establishing this relationship.
However, much controversy in the industrial sphere revolves
round the question of wages. Though formerly the laissez
faire doctrine prevailed, with the emergence of the welfare
state ideology, notions of national economy and social
justice gained prominence. The problem of wages has became
one with social, political, economic, psychological and
legal dimensions.
Formulation of a proper wage policy is thus a riddle.
Realities of the present have to be fused with perspectives
about the future. With due recognition of all significant
factors, a proper balance has to be struck, which should
be the hard core of any wage policy. This study emphasises
the need for a wage policy which may meet the requirements
of rapid economic growth and stable industrial relations.
The study also indicates the proper bases for the promotien
of such a policy.

Abstract:
Heavy metals are major toxic pollutants with severe health effects on
humans. They are released into the environment from a variety of industrial
activities. Cadmium, lead, zinc, chromium and copper are the most toxic
metals of widespread use in industries such as tanning, electroplating,
electronic equipment manufacturing and chemical processing plants. Heavy
metals contribute to a variety of adverse health environmental effects due to
their acute and chronic exposure through air, water and food chain.
Conventional treatment methods of metal removal are often limited by their
cost and ineffectiveness at low concentrations. Adsorption, the use of
inactivated biomass as adsorbents offers an attractive potential alternative to
their conventional methods. Mango peel and Alisma plantago aquatica are
naturally occurring and abundant biomass can offer an economical solution for
metal removal.The Cd(II), Pb(II), Zn(II), Cr(III) and Cu(II) adsorption by milled
adsorbents of mango peel and Alisma plantago aquatica were evaluated in
batches.

Abstract:
At intermediate depths of the Arabian Sea, the circulation and characteristics of water are more
influenced by the high saline waters from the north and low saline waters from the south of equator. The interaction of these waters which greatly differ in characteristics is less understood compared to that at the upper layers. An understanding of the nature of the intermediate waters is of vital importance not only because of the unusual characteristics of the waters but also due to the influx of the different water masses from the neighbouring Red Sea and Persian Gulf. Hence, in the present investigation, it is proposed to study the water characteristics and current structure of the intermediate waters in the Arabian Sea through the distribution of the water properties on the isanosteric surfaces of 100, 80, 60 and 4O—cl/t, vertical sections, and scatter diagrams An attempt is also made to present the potential vorticity between different steric levels to understand the circulation and mixing processes. Data collected during and subsequent to International Indian Ocean Expedition (IIOE) are used for this study. The thesis has been divided into six chapters with further sub divisions

Abstract:
The Kerala Water Authority requested the School of Environmental Studies to
carry out investigations on the mechanism of sporadic mobilization of iron and
odour in the raw water drawn to the drinking water treatment plant. The
currently used treatment process failed to remove iron completely. This led to
problems in the filter and complaints of taste and colour due to iron in the
finished water. The sporadic nature of the problem itself made the trouble
shooting difficult.
The problem was looked in from three points of view.
1. Influence of environmental (climatic) conditions on the dynamics of
the relevant basin of the reservoir.
2. Influence of the physical dynamics on the physico — chemical quality
of water.
3. Identification of cost-effective treatment processes to suit the existing
plant.
Since the problem emerged only during the post- monsoon to pre-monsoon
months, a related problem was investigated, namely, influence of anions on
the oxidation of Fe(II) in natural waters by air. This is presented in Part II of
the dissertation.

Abstract:
Investigations on the water relations and gas exchange of/tcacia aun'culiji_2rmis
were carried out in natural and controlled environments. The experiments were
performed in both seedlings and five year old trees. Different sets of experiments
were conducted in Acacia plantations, at Kothachira, Palakkad District and in
.seedlings, at KFRI campus nursery mainly during the summer months. Investigations
were also extended to seedlings of A.mangium, Aaulacocarpa and /Lholocericea,
which are also phyllodinous species with the intention of comparing their physiology
with Acacia auriculifomus.
Potted seedlings of four species of Acacia viz., A. auriculi/E)/7r:i.r, /I.
aulacocarpa, A. holocericea and A. mangium were used for the study.
Measurements of relative water content (RWC), water potential, photosynthetic rate,
transpiration, stomatal conductance, water use efficiency etc. of phyllodes were
measured diumally in plants subjected to three stress conditions namely, drought,
salinity and flooding

Abstract:
There are basically two methods for prediction of
shallow water waves, viz. the graphical method and the
numerical method. The numerical methods are being widely
used, now—a—days, because they are fast, accurate and are
especially useful when the prediction over a large spatial
frame is required. Practically little has been done on the
development of numerical models for the prediction of height
and spectral transformation of waves as applicable to our
coasts. Synchronized deep and shallow water wave measurements
which are essential for study of wave transformation are
very much lacking for our coasts. Under these
circumstances, a comprehensive study of the wave
transformation in the shallow waters of our coast was felt
very important and is undertaken in the present
investigation.

Abstract:
The Doctoral thesis focuses on the factors that influence the weather and climate
over Peninsular Indias. The first chapter provides a general introduction about the climatic features over peninsular India, various factors dealt in subsequent chapters, such as solar forcing on climate, SST variability in the northern Indian Ocean and its influence on Indian monsoon, moisture content of the atmosphere and its importance in the climate system, empirical formulation of regression forecast of climate and some aspects of regional climate modeling. Chapter 2 deals with the variability in the vertically integrated moisture (VIM) over Peninsular India on various time scales. The third Chapter discusses the influence of solar activity in the low frequency variability in the rainfall of Peninsular India. The study also investigates the influence of solar activity on the horizontal and vertical components of wind and the difference in the forcing before and after the so-called regime shift in the climate system before and after mid-1970s.In Chapter 4 on Peninsular Indian Rainfall and its association with meteorological and oceanic parameters over adjoining oceanic region, a linear regression model was developed and tested for the seasonal rainfall prediction of Peninsular India.

Abstract:
The present study is the first comprehensive approach towards histopathology of White Spot Syndrome Virus (WSSV) in Penaeus indicus. WSSV could be demonstrated in the nuclei of all tissues, except those of midgut, subjected of electron microscopic observation. They were the nuclei of gill, foregut, heart, hepatopancreatic connective tissue, hindgut, nerve and dorsal aorta. A comparison was made between the electron microscopic and histopathological observations and a greater degree of correlation between the two in depicting the severity of the infection of the infection was unraveled. The study also illustrated variations in response and susceptibility of various tissues to WSSV infection. Accordingly, out of the tissues investigated, gill, foregut, hindgut and dorsal aorta exhibited advanced viral multiplication than the other tissues such as heart, midgut, nerve and hepatopancreas. Even though hepatocytes were not infected the connective tissue nuclei were packed with virions.

Abstract:
The onset of spontaneous seizures triggers a cascade of molecular and cellular events that eventually leads to neuronal injury and cognitive decline. The present study investigated the effect of Withania somnifera (WS) root extract and Withanolide A (WA) in restoring behavioural deficit by inhibiting oxidative stress induced alteration in glutamergic neurotransmission. The subdued performance in
behavioural tests shows impaired motor coordination and memory. Histopathological investigations revealed significant neuronal loss in hippocampus of epileptic rats indicating glutamate mediated excitotoxicity. The treatment with WS and WA restored behavioural deficit and ameliorated neuronal loss. An altered redox homeostasis leading to oxidative stress is a hallmark of TLE. The antioxidant potential was afflicted in epileptic rats, evident from altered activity of SOD and CAT, down regulation of SOD and GPX expression and enhanced lipid peroxidation. The antioxidant property of WS and WA restored altered antioxidant capacity. Alteration in GDH activity and down regulation of GLAST expression resulted in enhanced glutamate content in the brain regions. The metabolism of glutamate was altered in the form of down regulated GAD expression. The alteration in synthesis, transport and metabolism resulted in further increase of the glutamate concentration at the synapse leading to glutamate mediated excitotoxicity. The decreased NMDA and AMPA receptor binding and down
regulated NMDA R1, NMDA 2B and AMPA (GluR2) mRNA expression indicated altered glutamergic receptor function. The treatment with WS and WA reversed altered glutamergic receptor function, synthesis, transport and metabolism. The enhanced levels of second messenger IP3 responsible for Ca2+ mediated toxicity was reversed after treatment with WS and WA. Neurotoxics concentration of glutamate resulted in up regulation of pro apoptotic factors Bax and Caspase 8 and down regulation of anti apoptotic factor Akt resulting in neuronal death. The treatment with WS and WA resulted in activation of Akt and down regulation of Bax and caspase 8 leading to blocking of apoptotic pathway.
The treatment with WS and WA resulted in reduced seizure frequency and amelioration of associated alterations suggesting the therapeutic role of Withania somnifera in temporal lobe epilepsy

Abstract:
The corporate views on wives roles and their subsequent involvement in their husbands career seem to be quiet surprising .Even though the corporate magnates are aware of wives influence on husbands professional advancements they seldom give credit to this factor. Again it may be an eye opener for the corporations which hardly take note of the executives wives their likes or dislikes, their expectations or frustrations. They are to understand that man in his totality and decisions affecting his family have to be taken seriously. More over they should respect the right of the wives by understanding the exact role played by them. Thus this study is to understand the roles and contributions of executives wives to the success of their husbands in their professions. The study tries to minimize the gap between the corporations and the wives ,and also to make the wives aware of their peculiar role in the career advancement of their executive husbands.
