Abstract:
In everyday life different flows of customers to avail some service facility or other at some service station are experienced. In some of these situations, congestion of items arriving for service, because an item cannot be serviced Immediately on arrival, is unavoidable. A queuing system can be described as customers arriving for service, waiting for service if it is not immediate, and if having waited for service, leaving the system after being served. Examples Include shoppers waiting in front of checkout stands in a supermarket, Programs waiting to be processed by a digital computer, ships in the harbor Waiting to be unloaded, persons waiting at railway booking office etc. A queuing system is specified completely by the following characteristics: input or arrival pattern, service pattern, number of service channels, System capacity, queue discipline and number of service stages. The ultimate objective of solving queuing models is to determine the characteristics that measure the performance of the system

Abstract:
This is a study in labour law.. Dismissal of workmen in private lndustrial sector is the area of this study. Confined within the framework of the Industrial Disputes act 1947, the study is an analytical assessment of the decisions of the supreme Court of India. on dismissal in industrial
employment. Few attempts were made in the past to analyse on identical lines the problems in this area. Hence what is| written in this thesis is ones own. Dismissal carries a stigma. the dismissed employee may find it difficult to get alternative employment especially in a land of severe unemployment. The need for law with built in safeguards against arbitrary dismissal cannot be overemphasized. From this perspective the study examines to what extent the industrial disputes act 1947 provides protection and how far the protection is adequate.

Abstract:
This thesis Entitled distribution ,diversity and biology of deep-sea fishes the indian Eez.Fishing rights and responsibilities it entails in the deep-sea sector has been a vexed issue since the mid-nineties and various stakeholders have different opinion on the modalities of harnessing the marine fisheries wealth, especially from the oceanic and deeper waters. The exploitation and utilization of these esources requires technology development and upgradation in harvest and post-harvest areas; besides shore infrastructure for berthing, handling, storing and processing facilities. At present, although deep-sea fishes don’t have any ready market in our country it can be converted into value added products.
Many problems have so far confronted the deep-sea fishing sector not allowing it to reach its full potential. Hence, there should be a sound deep-sea fishing policy revolving round the upgradation of the capabilities of small scale fishermen, who have the inherent skills but do not have adequate support to develop themselves and to acquire vessels having the capability to operate in farther and deeper waters. Prospects for the commercial exploitation and utilization of deep-sea fishes were analyzed using SWOL analysis.

Abstract:
The thesis deals with the prevalence and distribution of motile aeromonads in selected ornamental fishes. The presence of motile aeromonads in ornamental fishes and associated carriage water is well documented. Though aeromonads are a part of autochthonous flora of natural waters, disease outbreak occurs as a result of
environmental stress on the cultured species and virulence of the pathogens.
While ornamental aquaculture in many parts of the world is highly organized and
practiced scientifically, it is highly unorganized in India. The culture ponds/tanks
are often maintained in very poor manner and the fishes are subjected to high
degree of stress during transportation from the production facility to retail
vendors. The situation is no better at retail outlets, where fishes are maintained in
crowded condition without proper aeration or food. All these could result in high
prevalence of diseases caused by motile aeromonads. No systematic study has been carried out to understand the prevalence of motile aeromonads in ornamental fishes and carriage water . It also gives an account of the production of extracellular virulence factors and the antibiogram of the different species of motile aeromonads isolated. The growth characteristics and virulence potential of a representative strain of Aeromonas hydrophila is also studied. The nucleotide sequencing of the strain was carried out and sequences deposited in Genbank. Survival and immune response of Cyprinus carpio under different stress conditions and on probiotic treatment with Bacillus NL110, when challenged with A. hydrophila is also dealt within this thesis.

Abstract:
The study revealed stress and localized impact of industrial waste on the biota, predominance of stress tolerant species and low diversity in the vicinity of the effluent discharge point. These studies on impact of environmental parameters on the distribution of macrobenthos thus indicate the quantum of endurance warranted by the infauna to tide over the wide range of environmental stress. Low diversity and lower number of benthic fauna near discharge site can be attributed to the stress caused by cumulative toxic effects of effluents. The results of the physico-chemical parameters highlight the effects of pollution. The results of the study indicated the changes due to the large-scale movements of the estuarine water under the influence of tide, monsoon and land runoff coupled with its heterogenous nature owing to the effluent discharge from the industries

Abstract:
When we consider Kerala and Karnataka States according
to their levels of decentralisation. Kerala is at the beginning
of the scale of decentralisation whereas Kamataka has moved far
ahead along this scale. Therefore I in order to conduct a comparative
study of the SUbject under analysis t Kamataka has been selected
owing to the fact that it is in an advanced stage in the experience
of district planning compared to Kerala , Karnataka could successfully
implement district planning and it is me of the pioneering states
in this regard. But Kerala has not gained much experience in
the field of decentralised district planning till now. Furthermore
Kerala and Kamataka states are selected for the present study
due to operational reasons I besides the author I s familiarity with
the socia-economic conditions of these states. Thus. an analysis
of the district planning experience of Kamataka will provide
constructive and valuable information. which will be of great
importance to Kerala State, which is now aspiring to introduce
ful.I-f'Iedge district planning by constituting elected District Coancils
in every district of Kerala. Moreover. the findings and policy
implications of the present study will be of immense help to
planners, politicians. administrators, academicians and people
at large.

Abstract:
The basic objective of the present study has been to observe the process and pattern of employment diversification among the rural women workers in Ernakulam district. The evidences are that the women workers in the rural areas of the state are being increasingly diversified into the tertiary sector. The clear cut evidence for the fact that in Kerala non-agricultural employment of rural women is increasing with more and more of them getting diversified into the tertiary sector. The women get more self esteem and recognition in terms of the work being done by them. In the urban areas of the state as a poverty eradicating measure the Kerala government has already introduced a new scheme under the banner of Kudumbasree. Another fact noticed in the study that the sectoral shift of women workers has posed a grave problem to the agricultural sector. The reluctance of workers to do manual jobs on land and the prevalence of high wages among the agricultural labours has left many a cultivable area fallow or has induced farmers to shift to less labour –intensive crops. The situation is expected to worsen in future as even the high wages fail to attract the young generation to this sector. To conclude the study has fulfilled all its objectives, viz; highlighting the rural employment structure in Kerala, examining the process, pattern, determinants and consequences of diversification among rural women workers in the sample villages. Being the first of its kind at the micro level in the state it contributes to the available literature in the area enriching the database that is crucially lacking for devising projects at the village and block-level. There exists ample scope for future research of similar nature in an urban background where the secondary data-sources are hinding towards a reversal of trends from non-agriculture to agriculture.

Abstract:
The study deals with the diversity in structural and spectural characteristics of some transition metal complexes derived from aldehyde based thiosemicarbazone ligands thiosemicarbazones are a family of compounds with beneficial biological activity viz., anticancer,antitumour, antifungal, antibacterial, antimalarial, antifilarial, antiviral and anti-HIV activities. Many thiosemicarbazone ligands and their complexes have been prepared and screened for their antimicrobial activity against various types of fungi and bacteria. The results prove that the compounds exhibit antimicrobial properties and it is important to note that in some cases metal chelates show more inhibitory effects than the parent ligands. The increased lipophilicity of these complexes seems to be responsible for their enhanced biological potency. Adverse biological activities of thiosemicarbazones have been widely studied in rats and in other species. The parameters measured show that copper complexes caused considerable oxidative stress and zinc zinc complexes behaved as antioxidants. It has applications on analytical field also. Some thiosemicarbazones produce highly colored complexes with metal ions. This thesis aims to synthesis some novel thiosemicarbazone ligands and their transition metal complexes together with their physico-chemical characterization.

Abstract:
The object of every law is to render justice. But sometimes the strict implementation of low may result in injustice. Under such circumstances equity will step in to prevent the injustice. Estoppel is one such concept evolved by equity for rendering justice even deviating from strict legal principles. This study is an analysis of the essence of the principle of estoppel, its scope, circumstances and application. The related principles known as estoppel by record, estoppel by deed, estoppel by representation, promissory estoppel, estoppel against public authority is also considered. Estoppel, originated from the sense of justice, equity and good consciousness has since developed through various judicial pronouncements. Further section 115 of the Evidence Act has statutorily recognized and laid down the principles of estoppel. But Section 115 of the Evidence Act or any other statute does not cover the modern development of estoppel in the form of promissory estoppel.

Abstract:
This is a study in international trade law. Documentary credits are the
most common method of payment for goods in international trade. In India also
these instruments are used both in national and international trade. The law
governing these transactions remains haphazard. This study identifies the
deficiencies in the regulatory framework for documentary credits in India. It
primarily focuses on those areas which exhibits a lack of equality and justice in
its operation. An attempt has also been made to identify the rights and duties of
parties involved in the transaction. The reasons for the increase of fraudulent
activities associated with the documents executed in the documentary credit
transactions are also examined. How far the law in India is sufficient to ensure
fair business practice in international trade financing is also examined.
Methodology adopted for the study is analytical. The statutory provisions, rules
and case laws under these provisions have been examined. An empirical study
by personal interview with the bankers is also made to ascertain the practice of
bankers in India.

Abstract:
In the present study a detailed investigation on the alterations of dopamine
and its receptors in the brain regions of streptozotocin induced diabetic and insulin
induced hypoglycaemic rats were carried out. Glutamate receptor, NMDARI gene
expression in the hypoglycaemic and hyperglycaemic brain was also studied. EEG
recording in hypoglycaemic and hyperglycaemic will be carried out to measure brain
activity. in vitro studies on glucose uptake and insulin secretion, with and without
specific antagonists were carried out to confirm the specific receptor subtypes - DA
D1, DA D2 and NMDA involved in the functional regulation during hyperglycaemic
and hypoglycaemic brain damage. The molecular studies on the brain damage
through dopaminergic and glutamergic receptors will elucidate the therapeutic role in
the corrective measures of the damage to the brain during hypoglycaemia and
hyperglycaemia. This has importance in the management of diabetes and antidiabetic
treatment for better intellectual functioning of the individual.

Abstract:
Neuronal dopamine and serotonin receptors are widely distributed in the central and the peripheral nervous systems at different levels. Dopaminergic and serotonergic systems have crucial role in aldehyde dehydrogenase regulation Stimulation of autonomic nervous system during ethanol treatment is suggested to be an important factor in regulating the ALDH function. The ALDH enzyme activity was increased in plasma, cerebral cortex, and liver but decreased in cerebellum. The ALDH enzyme affinity was decreased in plasma, brainstem and liver and increased in cerebral cortex and cerebellum. Dopamine and serotonin content decreased in liver and brain regions - cerebral cortex, corpus striatum of ethanol treated rats with an increased HVA/DA, 5-HIAA/5-HT tumover rate. Dopamine content decreased in brainstem with an increased HVA/DA turnover rate and serotonin content decreased with an increased 5-HIAA/5-HT turnover rate in the brainstem of ethanol treated rats compared to control. Serotonin content increased in hypothalamus with a decreased 5-HIAA/5—HT turnover rate where as dopamine content decreased in hypothalamus with an increased HVA/DA tumover rate of ethanol treated rats compared to control.alterations of DA D2 and 5-HTQA receptor function and gene expression in the cerebellum, hypothalamus, corpus striatum, cerebral cortex play an important role in the sympathetic regulation of ALDH enzyme in ethanol addiction. There is a serotonergic and dopaminergic functional regulation of ALDH activity in the brain regions and liver of ethanol treated rats. Gene expression studies of DA D2 and 5'HT2A studies confirm these observations. Perfusion studies using DA, 5-HT and glucose showed ALDH regulatory function. Brain activity measeurement using EEG showed a prominentfrontal brain wave difference. This will have immense clinical significance in the management of ethanol addiction.
