L’injonction thérapeutique à l’égard des toxicomanes : comparaison des systèmes français et québécois

In Canada, the total amount of accusations, in compliance with the laws on drugs, show a slight but constant progression. More than half of the sentences for drug-linked offenses have lead to incarceration, a third of the people sentenced for a simple drug possession have been jailed. The relevance of these sentences, making the Canadian detention centres populated with more drug addicts than the rehabilitation centres, is questionable. In France, legislation is mostly based on the December 31st, 1970 law: drug use and trafficking are severely punished. However, for a first arrest, the prosecutor can enjoin the arrestee to treatment: this is what is called therapeutic injunction. Even though therapeutic injunction spares substance users from a jail term, some limitations are encountered this measure is selective, based on social and judicial criteria, making it more forgiving than the average characteristics of drug addicts, it is only accepted and applied by half of the subjects. A specific inquiry has been done in a department in the Paris region, where drug addiction activity is abundant, and suggested a preventive role for the injunction in cases of recidivism. Global appreciation of the therapeutic injunction remains nuanced in a context of new measures in drug addiction, but it translates into the increasing necessity to introduce professional networks between the judicial and sanitary systems, intended for a young population dealing with the modern difficulties of social adaptation and high risk behaviour.

Étude des discours experts sur la régulation et la criminalisation du trafic d'organes

La présente recherche décrit et examine la problématique posée par le trafic d’organes, de tissus et de cellules d’origine humaine, ainsi que les modes de régulation envisagés au niveau mondial pour lutter contre ce trafic, appréhendés sous l’angle de l’analyse de plusieurs conventions et protocoles internationaux et de leurs recommandations. Nous avons sélectionné, analysé et comparé les discours les plus significatifs de quatre types d’organisations internationales, les associations médicales internationales, l’Organisation des Nations Unies, l’Organisation mondiale de la Santé et le Conseil de l’Europe. Nous avons cherché à connaître leur point de vue sur la commercialisation des organes humains et plus spécifiquement sur le trafic des organes humains, à travers 17 textes que ces acteurs ont produit de 1987 jusqu’en 2014. L’analyse de ces discours experts révèle que la perspective éthique domine l’ensemble des documents. Elle met en évidence les convergences des discours sur la nécessité d’adopter une double stratégie fondée à la fois sur la prévention et la criminalisation du trafic d’organes ainsi que sur l’analyse du lien existant entre la pénurie croissante d’organes et l’avènement du trafic d’organes. Les discours sur la régulation et la criminalisation ont évolué vers un degré de précision et de complexification de la notion du trafic d’organes, une notion qui reste encore peu consensuelle dans sa définition. Quant aux stratégies, il faut observer que l’évolution des discours est assez significative et inégale à ce chapitre. C’est surtout dans les discours experts produits à partir des années 2000 que nous retrouvons des propositions plus concrètes sur les stratégies. La régulation des transactions financières, notamment par les balises de pratiques médicales et celles des intermédiaires, ainsi que les prescriptions entourant le consentement forment les deux types de stratégies les plus souvent mises de l’avant par les experts, toutes organisations confondues. Au fil de l’analyse des textes sur la régulation il est possible d’entrevoir des nuances et des brèches dans le principe d’interdiction de la commercialisation des organes humains, plus précisément en ce qui concerne les types d’organes, de tissus ou de cellules.

La génétique inverse dans l'étude des réovirus: Progrès, obstacles et développements futurs

En génétique dite « classique », l’examen d’un phénotype conduit à l’étude des gènes impliqués dans son obtention. La génétique inverse est une méthode expérimentale très puissante dans laquelle, au contraire, le matériel génétique est modifié et utilisé pour reconstruire un organisme complet, afin de déterminer le résultat de ces modifications. Cette approche est spécialement bien adaptée à l'étude des virus, compte tenu de la relative simplicité et de la petite taille de leurs génomes; l’obstacle principal demeure de récupérer des virus infectieux à partir de génomes viraux clonés. Au cours des années, cet exploit a été accompli pour des représentants de presque toutes les familles de virus de mammifères. Jusqu’à récemment, les Reoviridae, virus à génome d'ARN bicaténaire segmenté, faisaient toutefois exception. Dans cette revue, les progrès réalisés vers la mise au point de la génétique inverse pour l'étude du réovirus seront discutés. La génétique inverse pourrait avoir un impact majeur dans l'optimisation de nouvelles souches de réovirus pour leur utilisation en thérapie comme agents oncolytiques et pour le développement de vaccins dans le cas des rotavirus et des orbivirus. Les travaux actuels font toutefois ressortir les limites de l'approche, la nécessité d’une analyse prudente des résultats obtenus, ainsi que le besoin de développer des systèmes plus efficaces et polyvalents.

Vers une autre temporalité de la "parthénos" : entre mythe, littérature et disciplines du corps

Cette thèse trace la généalogie culturelle de la jeune fille en Occident en ciblant les moments charnières de son devenir femme au sein de structures de savoir qui ont activement participé à forger cette figure hétéronormative. Mon objectif est de produire une analyse culturelle en forgeant une cartographie des adolescences au féminin. Afin de sortir de la temporalité téléologique de la virginité et de la défloration, j’emprunte un mot étranger, parthénos, qui fait appel à l’idée de la jeune fille, sans nécessairement se limiter à ses connotations conventionnelles. La première partie, intitulée « La virginité, une affaire de jeunes filles », laisse place à une analyse du concept de parthénos à partir d’une lecture au carrefour de la médecine, de la loi et du mythe. Une lecture du traité hippocratique De la maladie des jeunes filles dévoile comment la défloration et la grossesse deviennent une cure érotique, une discipline du corps, qui décide du passage de la jeune fille dans une temporalité utile à la Cité. Un déplacement paradigmatique s’opère au 19e siècle dans les écrits médico-légaux, parce que l’hymen, auparavant inexistant dans la doxa hippocratique, devient le signe matériel par excellence pour examiner le statut de virginité de la fille. L’analyse de ces traités (frères Beck, Ambroise Tardieu, Paulier et Hétet) révèle la configuration de pratiques et de discours d’infantilisation des victimes de viol, et le refus des médecins légistes de reconnaître qu’une femme mariée puisse être violée. À partir d’une lecture contemporaine des tragédies L’Orestie d’Eschyle et Antigone de Sophocle, je montre que les figures d’Antigone et d’Électre constituent des exemples et des symboles convaincants de ce destin funeste de la parthénos qui n’accède jamais au statut de femme mariée. À ces figures mortelles, se télescopent les figures d’Artémis et des Érinyes pour montrer le potentiel de régénération inhérent à la figure de la parthénos. La deuxième partie, qui porte le titre « Le liminaire. Repenser les devenirs de l’adolescence », engage une réflexion à la lisière du contexte contemporain des Girlhood Studies, de la psychanalyse sociale et des études féministes sur le corps et le sexe, pour faciliter le déploiement d’une cartographie plus contextualisée du concept de parthénos. Je montre ici les écueils et les effets du danger qu’engendre la rationalité économique (cf. Henry A. Giroux) pour les espaces de liberté et d’exploration propres à l’adolescence. Cette posture est appuyée sur une lecture des récentes études en psychanalyse sociale (Anne Bourgain, Olivier Douville et Edmond Ortigues). Il est ainsi question d’identifier ce qui marque le passage entre l’adolescence et l’âge adulte : la crainte de la disparition et le fantasme de la naissance de soi. La théorie de la volatilité corporelle qu’élabore Elizabeth Grosz à propos de la sexualité féminine, ainsi que les théories de Michel Foucault, reprises par Judith Butler, en ce qui concerne les disciplines du corps, répondent à mon objectif de sortir de l’écueil d’une temporalité téléologique pour saisir les effets et les ramifications du discours sur la matérialité du corps de la jeune fille, sur ce qui lui arrive lorsqu’elle ne correspond pas tout à fait à l’idéal de régulation. Enfin, la dernière partie, qui porte le titre « Temporalités de la parthénos en tant que sujet liminaire », est traversée par les modalités particulières de la parthénia qui semble désincarnée dans la littérature contemporaine. L’objectif est de prouver que la virginité est toujours un marqueur symbolique qui déploie le destin de la fille dans un horizon particulier, trop souvent celui de la disparition. En proposant un éventail de cinq textes littéraires que j’inscris au sein d’une posture généalogique, je souhaite voir dans la littérature contemporaine, une volonté, parfois aussi un échec, dans cette pensée de la parthénos en tant que sujet liminaire. Le récit Vu du ciel de Christine Angot montre que l’ascension vers le statut d’ange concerne seulement les victimes enfants. Le récit d’Angot met donc en lumière la distinction entre la vraie victime, toujours innocente et pré-pubère, et la fausse victime, l’adolescente. Contrairement à Vu du ciel, The Lovely Bones d’Alice Sebold met en scène la possibilité d’une communauté politique de filles qui sera en fait limitée par le refus du potentiel lesbien. La question du viol sera ici centrale et sera abordée à partir de l’insistance sur la voix de la narratrice Susan. La littérature devient un espace propice à la survie de la jeune fille, puisqu’elle admet la reprise de l’expérience de la première relation sexuelle. Si la communauté est convoquée dans The Lovely Bones, elle est associée à l’image de l’identité sororale dans le roman Virgin Suicides de Jeffrey Eugenides. La pathologie virale et la beauté virginale que construit le narrateur polyphonique et anonyme font exister le discours médical sur la maladie des vierges dans un contexte contemporain. Le récit médical rejoint alors le récit érotique puisque le narrateur devient médecin, détective et voyeur. À la différence de ces trois récits, Drames de princesses d’Elfriede Jelinek montre une parthénos, Blanche Neige, qui fait face à son agresseur pour s’inscrire dans une historicité discursive. Cette collision dialogique ranime le cycle tragique (celui d’une Antigone confrontant Créon) et traduit de nouveau le danger d’une superstructure sociétale composée d’images et de discours où la fille est construite comme un accessoire pour le plaisir éphémère de l’homme. À l’inverse de l’image de la vierge sacrée et désincarnée que proposent les récits d’Angot, de Sebold, d’Eugenides et de Jelinek, Virginie Despentes offre une autre réflexion dans Apocalypse bébé. Le personnage de Valentine est configuré comme une sœur des parthénoi qui préfère le suicide et la terreur à la domestication, faisant ainsi appel à une temporalité radicale et inachevable, celle de la fin de la jeune fille. Mon souhait est enfin de souligner la nécessité de penser au mérite autant épistémologique, intime que politique, d’explorer le temps des éclosions sexuelles de la fille par delà l’idée de la première relation sexuelle.

La pensée politique à l’époque de Justinien (527-565) : l’Ekthesis d’Agapète et le Dialogue de science politique

Le présent mémoire se donne pour fin d'étudier, en les replaçant au sein du contexte politique de leur époque, deux textes importants de la pensée politique de Justinien : l'Ekthesis d'Agapète le diacre, et le Dialogue de science politique. Ces deux textes représentent le point de vue de deux groupes d'acceptation de Constantinople – à savoir des groupes qui peuvent participer à l’élévation ou à la destitution d’un empereur : le clergé, et l'élite des sénateurs et des hauts-fonctionnaires. À partir de ce cadre conceptuel, il s'agira, pour ce mémoire, de définir les problématiques ayant trait à la fonction et la conception du pouvoir impérial et à la forme de l'État, telles que les présentent ces deux textes. À terme, devra émerger comme cadre interprétatif l'affrontement de deux tendances: d'une part, un hellénisme politique christianisé (associé au clergé), et, d'autre part, une romanité conjuguée à une vision néoplatonicienne du monde (associée à l'élite sénatoriale et fonctionnaire). Ces deux traditions posent des questions différentes. D'un côté, celle de l'orthodoxie de l'empereur et de la nécessité, pour ce dernier, de suivre les préceptes de l'éthique chrétienne, de se montrer digne de Dieu, dont il est le serviteur; de l'autre, celle de la sauvegarde de l'héritage romain, portant notamment sur le rôle du Sénat et l’importance de la loi, de même que le lien entre empereur et philosophe.

Bodies, stories, cities : learning to read and write (in) Montréal with Gail Scott

Cette lecture, tant critique, comparative, et théorique que pédagogique, s’ancre dans le constat, premièrement, qu’il advient aux étudiantEs en littérature de se (re)poser la question des coûts et complicités qu’apprendre à lire et à écrire présuppose aujourd’hui; deuxièmement, que nos pratiques littéraires se trament au sein de lieux empreints de différences, que l’on peut nommer, selon le contexte, métaphore, récit, ville; et, troisièmement, que les efforts et investissements requis sont tout autant couteux et interminable qu’un plaisir et une nécessité politique. Ces conclusions tendent vers l’abstrait et le théorique, mais le langage en lequel elles sont articulées, langage corporel et urbain, de la dépendance et de la violence, cherche d’autant plus une qualité matérielle et concrète. Or, l’introduction propose un survol des lectures et comparaisons de Heroine de Gail Scott qui centre ce projet; identifie les contextes institutionnels, historiques, et personnels qui risquent, ensuite, de décentrer celui-ci. Le premier chapitre permet de cerner le matérialisme littéraire qui me sert de méthode par laquelle la littérature, à la fois, sollicite et offre une réponse à ces interrogations théoriques. Inspirée de l’œuvre de Gail Scott et Réjean Ducharme, premièrement, et de Walter Benjamin, Elisabeth Grosz, et Pierre Macherey ensuite, ‘matérialisme’ fait référence à cette collection de figures de pratiques littéraires et urbaines qui proviennent, par exemple, de Georges Perec, Michel DeCerteau, Barbara Johnson, et Patricia Smart, et qui invitent ensuite une réflexions sur les relations entre corporalité et narrativité, entre la nécessité et la contingence du littéraire. De plus, une collection de figures d’un Montréal littéraire et d’une cité pédagogique, acquis des œuvres de Zygmunt Bauman, Partricia Godbout, et Lewis Mumford, constitue en effet un vocabulaire nous permettant de mieux découvrir (et donc enseigner) ce que lire et apprendre requiert. Le deuxième chapitre propose une lecture comparée de Heroine et des romans des auteures québécoises Anne Dandurand, Marie Gagnon, et Tess Fragoulis, dans le contexte, premièrement, les débats entourant l’institutionnalisation de la littérature (anglo)Québécoise et, deuxièmement, des questions pédagogiques et politiques plus larges et plus urgentes que nous pose, encore aujourd’hui, cette violence récurrente qui s’acharna, par exemple, sur la Polytechnique en 1989. Or, cette intersection de la violence meurtrière, la pratique littéraire, et la pédagogie qui en résulte se pose et s’articule, encore, par le biais d’une collection de figures de styles. En fait, à travers le roman de Scott et de l’œuvre critique qui en fait la lecture, une série de craques invite à reconnaître Heroine comme étant, ce que j’appelle, un récit de dépendance, au sein duquel se concrétise une temporalité récursive et une logique d’introjection nous permettant de mieux comprendre la violence et, par conséquent, le pouvoir d’une pratique littéraire sur laquelle, ensuite, j’appuie ma pédagogie en devenir. Jetant, finalement, un regard rétrospectif sur l’oeuvre dans son entier, la conclusion de ce projet se tourne aussi vers l’avant, c’est-à-dire, vers ce que mes lectures dites matérialistes de la littérature canadienne et québécoise contribuent à mon enseignement de la langue anglaise en Corée du Sud. C’est dans ce contexte que les propos de Jacques Rancière occasionnent un dernier questionnement quant à l’historique des débats et des structures pédagogiques en Corée, d’une part, et, de l’autre, les conclusions que cette lecture de la fiction théorique de Gail Scott nous livre.

STUDY OF INFLUENCE OF SAFETY ENGINEERING AND MANAGEMENT PRACTICES IN SELECTED INDUSTRIES IN KERALA

In the twentieth century, as technology grew with it. This resulted in collective efforts and thinking in the direction of controlling work related hazards and accidents. Thus, safety management developed and became an important part of industrial management. While considerable research has been reported on the topic of safety management in industries from various parts of the world, there is scarcity of literature from India. It is logical to think that a clear understanding of the critical safety management practices and their relationships with accident rates and management system certifications would help in the development and implementation of safety management systems. In the first phase of research, a set of six critical safety management practices has been identified based on a thorough review of the prescriptive, practitioner, conceptual and empirical literature. An instrument for measuring the level of practice of these safety conduction a survey using questionnaire in chemical/process industry. The instrument has been empirically validated using Confirmatory Factor Analysis (CFA) approach. As the second step. Predictive validity of safety management practices and the relationship between safety management practices and self-reported accident rates and management system certifications have been investigated using ANOVA. Results of the ANOVA tests show that there is significant difference in the identified safety management practices and the determinants of safety performance have been investigated using Multiple Regression Analysis. The inter-relationships between safety management practices, determinants of safety performance and components of safety performance have been investigated with the help of structural equation modeling. Further investigations into engineering and construction industries reveal that safety climate factors are not stable across industries. However, some factors are found to be common in industries irrespective of the type of industry. This study identifies the critical safety management practices in major accident hazard chemical/process industry from the perspective of employees and the findings empirically support the necessity for obtaining safety specific management system certifications

Analytical Investigations 0n Collapse of Cylindrical Submarine Shells

Submarine hull structure is a watertight envelope, under hydrostatic pressure when in operation. Stiffened cylindrical shells constitute the major portion of these submarine hulls and these thin shells under compression are susceptible to buckling failure. Normally loss of stability occurs at the limit point rather than at the bifurcation point and the stability analysis has to consider the change in geometry at each load step. Hence geometric nonlinear analysis of the shell forms becomes. a necessity. External hydrostatic pressure will follow the deformed configuration of the shell and hence follower force effect has to be accounted for. Computer codes have been developed based on all-cubic axisymmetric cylindrical shell finite element and discrete ring stiffener element for linear elastic, linear buckling and geometric nonIinear analysis of stiffened cylindrical shells. These analysis programs have the capability to treat hydrostatic pressure as a radial load and as a follower force. Analytical investigations are carried out on two attack submarine cylindrical hull models besides standard benchmark problems. In each case, the analysis has been carried out for interstiffener, interdeepframe and interbulkhead configurations. The shell stiffener attachment in each of this configuration has been represented by the simply supported-simply supported, clamped-clamped and fixed-fixed boundary conditions in this study. The results of the analytical investigations have been discussed and the observations and conclusions are described. Rotation restraint at the ends is influential for interstiffener and interbulkhead configurations and the significance of axial restraint becomes predominant in the interbulkhead configuration. The follower force effect of hydrostatic pressure is not significant in interstiffener and interdeepframe configurations where as it has very high detrimental effect on buckling pressure on interbulkhead configuration. The geometric nonlinear interbulkhead analysis incorporating follower force effect gives the critical value of buckling pressure and this analysis is recommended for the determination of collapse pressure of stiffened cylindrical submarine shells.

Development of Best Practices for Ship Recycling Processes

Ship recycling has been considered as the best means to dispose off an obsolete ship. The current state of art of technology combined with the demands of sustainable developments from the global maritime industrial sector has modified the status of erstwhile ‘ship breaking’ involving ship scrap business to a modern industry undertaking dismantling of ships and recycling/reusing the dismantled products in a supply chain of pre owned product market by following the principles of recycling. Industries will have to formulate a set of best practices and blend them with the engineering activities for producing better quality products, improving the productivity and for achieving improved performances related to sustainable development. Improved performance by industries in a sustainable development perspective is accomplished only by implementing the 4E principles, ie.,. ecofriendliness, engineering efficiency, energy conservation and ergonomics in their core operations. The present study has done a comprehensive investigation into various ship recycling operations for formulating a set of best practices.Being the ultimate life cycle stage of a ship, ship recycling activities incorporate certain commercial procedures well in advance to facilitate the objectives of dismantling and recycling/reusing of various parts of the vessel. Thorough knowledge regarding these background procedures in ship recycling is essential for examining and understanding the industrial business operations associated with it. As a first step, the practices followed in merchant shipping operations regarding the decision on decommissioning have been and made available in the thesis. Brief description about the positioning methods and important preparations for the most feasible ship recycling method ie.,. beach method have been provided as a part of the outline of the background information. Available sources of guidelines, codes and rules & regulations for ship recycling have been compiled and included in the discussion.Very brief summary of practices in major ship recycling destinations has been prepared and listed for providing an overview of the global ship recycling activities. The present status of ship recycling by treating it as a full fledged engineering industry has been brought out to establish the need for looking into the development of the best practices. Major engineering attributes of ship as a unique engineering product and the significant influencing factors on her life cycle stage operations have been studied and added to the information base on ship recycling. Role of ship recycling industry as an important player in global sustainable development efforts has been reviewed by analysing the benefits of ship recycling. A brief synopsis on the state of art of ship recycling in major international ship recycling centres has also been incorporated in the backdrop knowledgebase generation on ship recycling processes.Publications available in this field have been reviewed and classified into five subject categories viz., Infrastructure for recycling yards and methods of dismantling, Rules regarding ship recycling activities, Environmental and safety aspects of ship recycling, Role of naval architects and ship classification societies, Application of information technology and Demand forecasting. The inference from the literature survey have been summarised and recorded. Noticeable observations in the inference include need of creation of a comprehensive knowledgebase on ship recycling and its effective implementation in the industry and the insignificant involvement of naval architects and shipbuilding engineers in ship recycling industry. These two important inferences and the message conveyed by them have been addressed with due importance in the subsequent part of the present study.As a part of the study the importance of demand forecasting in ship recycling has been introduced and presented. A sample input for ship recycling data for implementation of computer based methods of demand forecasting has been presented in this section of the thesis.The interdisciplinary nature of engineering processes involved in ship recycling has been identified as one of the important features of this industry. The present study has identified more than a dozen major stake holders in ship recycling having their own interests and roles. It has also been observed that most of the ship recycling activities is carried out in South East Asian countries where the beach based ship recycling is done in yards without proper infrastructure support. A model of beach based ship recycling has been developed and the roles, responsibilities and the mutual interactions of the elements of the system have been documented as a part of the study Subsequently the need of a generation of a wide knowledgebase on ship recycling activities as pointed out by the literature survey has been addressed. The information base and source of expertise required to build a broad knowledgebase on ship recycling operations have been identified and tabulated. Eleven important ship recycling processes have been identified and a brief sketch of steps involved in these processes have been examined and addressed in detail. Based on these findings, a detailed sequential disassembly process plan of ship recycling has been prepared and charted. After having established the need of best practices in ship recycling initially, the present study here identifies development of a user friendly expert system for ship recycling process as one of the constituents of the proposed best practises. A user friendly expert system has been developed for beach based ship recycling processes and is named as Ship Recycling Recommender (SRR). Two important functions of SRR, first one for the ‘Administrators’, the stake holders at the helm of the ship recycling affairs and second one for the ‘Users’, the stake holders who execute the actual dismantling have been presented by highlighting the steps involved in the execution of the software. The important output generated, ie.,. recommended practices for ship dismantling processes and safe handling information on materials present onboard have been presented with the help of ship recycling reports generated by the expert system. A brief account of necessity of having a ship recycling work content estimation as part of the best practices has been presented in the study. This is supported by a detailed work estimation schedule for the same as one of the appendices.As mentioned earlier, a definite lack of involvement of naval architect has been observed in development of methodologies for improving the status of ship recycling industry. Present study has put forward a holistic approach to review the status of ship recycling not simply as end of life activity of all ‘time expired’ vessels, but as a focal point of integrating all life cycle activities. A new engineering design philosophy targeting sustainable development of marine industrial domain, named design for ship recycling has been identified, formulated and presented. A new model of ship life cycle has been proposed by adding few stages to the traditional life cycle after analysing their critical role in accomplishing clean and safe end of life and partial dismantling of ships. Two applications of design for ship recycling viz, recyclability of ships and her products and allotment of Green Safety Index for ships have been presented as a part of implementation of the philosophy in actual practice.

Investigations on Structural response of Water Backed Perforated plates

The study envisaged herein contains the numerical investigations on Perforated Plate (PP) as well as numerical and experimental investigations on Perforated Plate with Lining (PPL) which has a variety of applications in underwater engineering especially related to defence applications. Finite element method has been adopted as the tool for analysis of PP and PPL. The commercial software ANSYS has been used for static and free vibration response evaluation, whereas ANSYS LS-DYNA has been used for shock analysis. SHELL63, SHELL93, SOLID45, SOLSH190, BEAM188 and FLUID30 finite elements available in the ANSYS library as well as SHELL193 and SOLID194 available in the ANSYS LS-DYNA library have been made use of. Unit cell of the PP and PPL which is a miniature of the original plate with 16 perforations have been used. Based upon the convergence characteristics, the utility of SHELL63 element for the analysis of PP and PPL, and the required mesh density are brought out. The effect of perforation, geometry and orientation of perforation, boundary conditions and lining plate are investigated for various configurations. Stress concentration and deflection factor are also studied. Based on these investigations, stadium geometry perforation with horizontal orientation is recommended for further analysis.Linear and nonlinear static analysis of PP and PPL subjected to unit normal pressure has been carried out besides the free vibration analysis. Shock analysis has also been carried out on these structural components. The analytical model measures 0.9m x 0.9m with stiffener of 0.3m interval. The influence of finite element, boundary conditions, and lining plate on linear static response has been estimated and presented. Comparison of behavior of PP and PPL in the nonlinear strain regime has been made using geometric nonlinear analysis. Free vibration analysis of the PP and PPL has been carried out ‘in vacuum’ condition and in water backed condition, and the influence of water backed condition and effect of perforation on natural frequency have been investigated.Based upon the studies on the vibration characteristics of NPP, PP and PPL in water backed condition and ‘in vacuum’ condition, the reduction in the natural frequency of the plate in immersed condition has been rightly brought out. The necessity to introduce the effect of water medium in the analysis of water backed underwater structure has been highlighted.Shock analysis of PP and PPL for three explosives viz., PEK, TNT and C4 has been carried out and deflection and stresses on plate as well as free field pressure have been estimated using ANSYS LS-DYNA. The effect of perforations and the effect of lining plate have been predicted. Experimental investigations of the measurement of free field pressure using PPL have been conducted in a shock tank. Free field pressure has been measured and has been validated with finite element analysis results. Besides, an experiment has been carried out on PPL, for the comparison of the static deflection predicted by finite element analysis.The distribution of the free field pressure and the estimation of differential pressure from experimentation and the provision for treating the differential pressure as the resistance, as a part of the design load for PPL, has been brought out.

Development of Safety and Quality Management System in Shrimp Farming

Shrimp Aquaculture has provided tremendous opportunity for the economic and social upliftment of rural communities in the coastal areas of our country Over a hundred thousand farmers, of whom about 90% belong to the small and marginal category, are engaged in shrimp farming. Penaeus monodon is the most predominant cultured species in India which is mainly exported to highly sophisticated, quality and safety conscious world markets. Food safety has been of concem to humankind since the dawn of history and the concern about food safety resulted in the evolution of a cost effective, food safety assurance method, the Hazard Analysis Critical Control Point (HACCP). Considering the major contribution of cultured Penaeus monodon to the total shrimp production and the economic losses encountered due to disease outbreak and also because traditional methods of quality control and end point inspection cannot guarantee the safety of our cultured seafood products, it is essential that science based preventive approaches like HACCP and Pre requisite Programmes (PRP) be implemented in our shrimp farming operations. PRP is considered as a support system which provides a solid foundation for HACCP. The safety of postlarvae (PL) supplied for brackish water shrimp farming has also become an issue of concern over the past few years. The quality and safety of hatchery produced seeds have been deteriorating and disease outbreaks have become very common in hatcheries. It is in this context that the necessity for following strict quarantine measures with standards and code of practices becomes significant. Though there were a lot of hue and cry on the need for extending the focus of seafood safety assurance from processing and exporting to the pre-harvest and hatchery rearing phases, an experimental move in this direction has been rare or nil. An integrated management system only can assure the effective control of the quality, hygiene and safety related issues. This study therefore aims at designing a safety and quality management system model for implementation in shrimp farming and hatchery operations by linking the concepts of HACCP and PRP.

Judicial Creativity in Constitutional Interpretation

The focus of study in this thesis is on the necessity and extent of judicial creativity in interpreting provisions in certain crucial areas in the Constitution of India. Judicial innovation was essential to adapt the constitutional provisions to modern changed context. Creativity of the Court has been mainly in the creation and introduction of certain new concepts not found in any specific provision of the Constitution which, but were essential for its meaningful interpretation.Independence of the judiciary, basic structure and certain elements of social justice cherished as ideal by the makers of the Constitution are some such concepts infused into the Constitution by the judiciary. The second aspect of creativity lies in the attempt of the Court to construe provisions in the Constitution with a view to upholding and maintaining the concepts so infused into the Constitution. Introduction of those concepts into the Constitution was necessary and is justified. all important features of the Constitution like democratic form of government, federal structure, judicial review, independence of judiciary and rule of law were thus included in the doctrine to prevent their alteration by amendments.As a result of such a construction, the nature of those directive principles itself has changed. They ceased to be mere directives for state action but became mandate for it. If left to legislative or executive will for their implementation, the directives would have remained enforceable as ordinary right.To conclude, notwithstanding the errors committed by the Supreme Court in construing the provisions in the above areas, they stand testimony to its creative and innovative response in interpreting the Constitution. If this trend is continued, it will be possible to achieve through the judicial process, maintenance of independence of the judiciary, avoidance of destruction of the Constitution through the process of amendment and realisation of social justice envisaged in the directive principles. It can be hoped that the Court would maintain its energetic and vibrant mind and rise up to the occasions and extend the same to other areas in future.

Studies on the meteriological aspects of air pollution over Cochin

Pollutants that once enter into the earth’s atmosphere become part of the atmosphere and hence their dispersion, dilution, direction of transportation etc. are governed by the meteorological conditions. The thesis deals with the study of the atmospheric dispersion capacity, wind climatology, atmospheric stability, pollutant distribution by means of a model and the suggestions for a comprehensive planning for the industrially developing city, Cochin. The definition, sources, types and effects of air pollution have been dealt with briefly. The influence of various meteorological parameters such as vector wind, temperature and its vertical structure and atmospheric stability in relation to pollutant dispersal have been studied. The importance of inversions, mixing heights, ventilation coefficients were brought out. The spatial variation of mixing heights studies for the first time on a microscale region, serves to delineate the regions of good and poor dispersal capacity. A study of wind direction fluctuation, σθ and its relation to stability and mixing heights were shown to be much useful. It was shown that there is a necessity to look into the method of σθ computation. The development of Gausssian Plume Model along with the application for multiple sources was presented. The pollutant chosen was sulphur dioxide and industrial sources alone were considered. The percentage frequency of occurrence of inversions and isothermals are found to be low in all months during the year. The spatial variation of mixing heights revealed that a single mixing height cannot be taken as a representative for the whole city have low mixing heights and monsoonal months showed lowest mixing heights. The study of ventilation co-efficients showed values less than the required optimum value 6000m2/5. However, the low values may be due to the consideration of surface wind alone instead of the vertically averaged wind. Relatively more calm conditions and light winds during night and strong winds during day time were observed. During the most of the year westerlies during day time and northeasterlies during night time are the dominant winds. Unstable conditions with high values of σθ during day time and stable conditions with lower values of σθ during night time are the prominent features. Monsoonal months showed neutral stability for most of the time. A study σθ of and Pasquill Stability category has revealed the difficulty in giving a unique value of for each stability category. For the first time regression equations have been developed relating mixing heights and σθ. A closer examination of σθ revealed that half of the range of wind direction fluctuations is to be taken, instead of one by sixth, to compute σθ. The spatial distribution of SO2 showed a more or less uniform distribution with a slight intrusion towards south. Winter months showed low concentrations contrary to the expectations. The variations of the concentration is found to be influenced more by the mixing height and the stack height rather than wind speed. In the densely populated areas the concentration is more than the threshold limit value. However, the values reported appear to be high, because no depletion of the material is assumed through dry or wet depositions and also because of the inclusion of calm conditions with a very light wind speed. A reduction of emission during night time with a consequent rise during day time would bring down the levels of pollution. The probable locations for the new industries could be the extreme southeast parts because the concentration towards the north falls off very quickly resulting low concentrations. In such a case pollutant spread would be towards south and west, thus keeping the city interior relatively free from pollution. A more detailed examination of the pollutant spread by means of models that would take the dry and wet depositions may be necessary. Nevertheless, the present model serves to give the trend of the distribution of pollutant concentration with which one can suggest the optimum locations for the new industries

Personal Finance of Gazetted Officers in Kerala

The purpose of personal financial management is achievement of personal financial freedom. It is a stage where finance will not be a hindrance against the fulfilment ofthe financial objectives of persons. After counting individual values and preferences we arrive at a standard or normal financial behaviour. Even though individuals differ in their tastes and preferences, there are a very large amount of commonality among them. The financial manager should list out the various financial objectives ofthe family. Then he should make the best choice from among the various alternatives on a priority based system. In short personal finance is concerned with the way in which a person manages his income and expenditure to achieve his personal financial objectives. Thus a proper personal financial planning is essential in every family for attaining financial discipline in the family. The fall ofthejoint family system, the growing financial responsibilities of modern families, limited chance ofincreasing income, growing population, financial insecurity of the government employees, lack of financial freedom, lack of proper personal financial practice and its awareness, the growing suicide rate on account offinancial crisis etc.,make the study a necessity

Development of Zero Water Exchange Shrimp Culture System Integrated With Bioremediation of Detritus and Ammonia- Nitrogen

Aquaculture is one of the fastest growing food sectors in the world. Amongst the various branches of aquaculture, shrimp culture has expanded rapidly across the globe because of its faster growth rate, short culture period, high export value and demand in the International market. Indian shrimp farming has experienced phenomenal development over the decades due to its excellent commercial viability. Farmers have adopted a number of innovative technologies to improve the production and to maximize the returns per unit area. The culture methods adopted can be classified in to extensive, modified extensive and semi intensive based on the management strategies adopted in terms of pond size, stocking density, feeding and environmental control. In all these systems water exchanges through the natural tidal effects, or pump fed either from creek or from estuaries is a common practice. In all the cases, the systems are prone to epizootics due to the pathogen introduction through the incoming water, either brought by vectors, reservoir hosts, infected tissue debris and free pathogens themselves. In this scenario, measures to prevent the introduction of pathogen have become a necessity to protect the crop from the onslaught of diseases as well as to prevent the discharge of waste water in to the culture environment.The present thesis deals with Standardization of bioremediation technology for zero water exchange shrimp culture system
