Contribution pulmonaire à l’élimination systémique du propofol chez le patient sous anesthésie générale

Diverses études cliniques ont démontré l’existence d’un métabolisme extrahépatique du propofol. Le lieu exact de ce métabolisme n’est pas encore complètement élucidé chez l’homme. Des données chez l’animal suggèreraient que le poumon pourrait contribuer à la clairance totale du propofol. Le présent projet vise à investiguer la contribution pulmonaire à l’élimination systémique du propofol chez des patients sous anesthésie générale. Quatorze patients de type ASA I ou II, âgés entre 35 et 70 ans, pour lesquels une chirurgie cardiaque de routine était prévue, ont été inclus dans la présente étude. Le protocole a été préalablement approuvé par le comité d’éthique et les patients ont tous donné par écrit leur consentement éclairé. Le recrutement des patients a eu lieu à l’hôpital Royal Victoria. Le propofol a été administré en induction sous forme de bolus intraveineux, suivi d’une perfusion continue de 50 g/kg/min. Chez un même patient, des prélèvements sanguins pré- et post pulmonaires ont été pris simultanément de l’artère radiale et de l’artère pulmonaire, sous des conditions de ventilation contrôlée ou apnéiques, dans le but de mesurer les concentrations plasmatiques du propofol. Le gradient artério-veineux a été évalué à l’état d’équilibre afin de déterminer la contribution du poumon à l’élimination totale de propofol. Nous n’avons pas pu démontrer l’existence d’une extraction pulmonaire du propofol chez l’humain. Ceci pourrait être dû à plusieurs facteurs méthodologiques.

Aspirations de la relève et nécessité de convaincre dans le culte du Teyyam

Le Teyyam est un rituel de possession hindouiste du Kerala (Inde du Sud) qui nécessite une pratique intransigeante : restrictions, jeûnes, exploits physiques, résistance à la chaleur du feu. Vêtus de costumes spectaculaires, des performeurs de caste intouchable dansent l’épée à la main, au son des tambours frénétiques, et font entendre la parole du dieu qu’ils incarnent; ils auront même le droit de critiquer le système des castes devant la communauté assemblée, le temps d’une inversion rituelle. Alors qu’autrefois il s’agissait d’un devoir de caste associé à une grande précarité, aujourd’hui il s’agit d’un métier que l’on peut choisir d’exercer ou non. Bien qu’on ait déploré un manque de relève à cause des conditions jugées trop difficiles, il y a toutefois de jeunes hommes qui ont décidé de poursuivre cette tradition ancestrale. Au Kerala, de nombreux jeunes aspirent à la classe moyenne et misent sur l’éducation pour espérer un bon emploi, il y a des opportunités, mais pas pour tous, et surtout beaucoup de compétition. C’est dans ce contexte que de jeunes hommes éduqués souhaitent poursuivre une tradition qu’ils admirent et dont ils sont fiers, mais sans avoir à sacrifier leurs chances de réussite sociale. Quelles sont leurs aspirations, quel sens donnent-ils à ce qu’ils souhaitent accomplir? Traditionnellement les relations de patronage dans le Teyyam ont été très dures sous le joug du système des castes, qu’en est-il aujourd’hui? Comment ces performeurs arrivent-il à négocier la réalisation de leurs aspirations dans les coulisses du Teyyam?

Effect of dietary sodium restriction on taste perception of sodium chloride

The effect of dietary sodium restriction on perceived intensity of and preference for the taste of salt was evaluated in 76 adults, 25-49 years, with diastolic blood pressure between 79-90 mmHg. Participants were volunteers from clinical Hypertension Prevention Trials (HPT), at the University of California, Davis and the University of Minnesota, Minneapolis. Participants followed one of four HPT diets: 1600 mg Na+/day (NA, n=lS), 1600 mg Na+ plus 3200 mg K+/day (NK, n=lS), 1600 mg Na+/day plus energy restriction to achieve weight loss (NW, n=l3) and weight loss only (WT, n=l3). All participants attended regularly scheduled nutri­tion intervention meetings designed to help them achieve the HPT dietary goals. A fifth, no-intervention group, consisted of 20, no-diet-change controls CCN). Sodium, potassium and energy intakes were monitored by analysis of single, 24-hour food records and corresponding overnight urine speci­mens, obtained at baseline and after 12 and 24 weeks of intervention. Hedonic responses to sodium chloride in a prepared cream of green bean soup were assessed by two methods : 1) scaling of like/dislike for an NaCl concentration series on 10-cm graphie line scales and 2) ad libitum mixing of unsalted and salted soups to maximum level of liking. Salt content of the mixes was analyzed by sodium ion-selective electrode. The concentration series was also rated for perceived saltiness­intensity on similar graphie line scales. Tests were conducted at base­line and after approximately 1, 3, 6, 8, 10, 13 and 24 weeks of intervention. Reduction in sodium intake and excretion in NA, NK and NW partici­pants was accompanied by a shift in preference toward less saltiness in soup. The pattern of hedonic responses changed over time: scores for high NaCl concentrations decreased progressively while scores for low concentrations increased. Hedonic maxima shifted fran a concentration of 0.55% at the onset to 0.1-0.2% added NaCl at week 24. During the same time period, the preferred concentration of ad libitum mixes declined 50%. These shifts occurred independently of changes in salti­ness intensity ratings, potassium or energy intakes, and were consistent across the two participating study sites. Like/dislike and sd. libitum responses were similar after 13 and 24 weeks of diet, as were measures of sodium intake and excretion. These findings suggest that after three months of sodium restriction, preference for salt had readjusted to a lower level, reflective of lower sodium intake. Mechanisms underlying the change in preference are unclear, but may include sensory, context, physiological as well as behavioral effects. In contrast, few changes were noted within WT and CN groups. The pattern of hedonic responses varied little in controls while the WT group showed increased liking for mid-range NaCl concentrations. Small, but significant fluctuations in ad libitum mix concentration occurred in both of these groups, but the differences appeared to be random rather than systematic. The results of this study indicate that preference for the taste of salt declines progressively toward a new baseline following reductions in sodium intake. These alterations may enhance maintenance of low­sodium diets for the treatment and prevention of hypertension. Further investigation is needed to establish the degree to which long-term com­pliance is contingent upon variation in salt taste preference.

Trends in Financial Intermediation by the Banking System in Kerala

The study documents the long-term trends in financial intermediation by the principal player in Kerala’s credit system i.e., banking. The process of financial intermediation by the banking system, involving mobilization of deposits from savers and disbursal of credit to investors, is considered to be crucial in the process of economic development. The objective of the study is to explore the interrelationship between financial intermediation and economic growth in Kerala. In order to pursue this objective, the study examine, the trends in intermediation by the banking system in Kerala over a long period, the trend and pattern of bank deposits and credit in the State and Kerala’s economic growth, the trend in the growth and performance of financial intermediaries like the All India Financial Institutions, the links between banking and economic variables, and the difference in the growth trends of banking and economic variables between Kerala and India and the probable reasons for the difference

Studies Using Computer Simulation Models to Solve Problems Related to Logistics Terminals

This thesis deals with the use of simulation as a problem-solving tool to solve a few logistic system related problems. More specifically it relates to studies on transport terminals. Transport terminals are key elements in the supply chains of industrial systems. One of the problems related to use of simulation is that of the multiplicity of models needed to study different problems. There is a need for development of methodologies related to conceptual modelling which will help reduce the number of models needed. Three different logistic terminal systems Viz. a railway yard, container terminal of apart and airport terminal were selected as cases for this study. The standard methodology for simulation development consisting of system study and data collection, conceptual model design, detailed model design and development, model verification and validation, experimentation, and analysis of results, reporting of finding were carried out. We found that models could be classified into tightly pre-scheduled, moderately pre-scheduled and unscheduled systems. Three types simulation models( called TYPE 1, TYPE 2 and TYPE 3) of various terminal operations were developed in the simulation package Extend. All models were of the type discrete-event simulation. Simulation models were successfully used to help solve strategic, tactical and operational problems related to three important logistic terminals as set in our objectives. From the point of contribution to conceptual modelling we have demonstrated that clubbing problems into operational, tactical and strategic and matching them with tightly pre-scheduled, moderately pre-scheduled and unscheduled systems is a good workable approach which reduces the number of models needed to study different terminal related problems.

The Right to Freedom of Information in Inida

This thesis entitled “The right to freedom of information in india”.In a democracy, the citizens being the persons to choose their own governors, the right to know from the Government is a pre-condition for a properly evaluated election. Freedom of speech and expression, one of the repositories of self~government, forms the basis for the right to know in a wider scale. The functions which the free speech rights serve in a society also emphasize the need for more openness in the functioning of a democracy.Maintanance of law and order and investigation of crimes are highly important in a country like India, where no risk may be taken on account of the public‘s right to know. The Indian situations relating terrorist activities, riots based on language, region, religion and caste are important in this respect. The right to know of the citizens may be regulated in the interests of secrecy required in these areas.On the basis of the conclusions reached in this study, a draft Bill has been proposed for the passing of an Access to Public Documents Act. This Bill is appended to this Thesis.

Legal Control of Industrial Pollution

Industries constitute the main spring of development. Without industrial development no country could reach a stage in which a decent living for its citizens would be achieved. Increasing production to meet the basic needs of society augmented scientific invention and machine oriented industrial order.Environmental pollution ls a burning global issue. It is more serious and dangerous than terrorism. Started with the discovery of fire and development of civilization. Pollution went unnoticed throughout the centuries of human growth until its adverse effects on human environment become explicit.National concern tor environment started in our country only atter the cause of protection of environment received global attention. At present legal control ot industrial pollution is in a scattered framework of piece meal processes with overlapping provisions and authorities.Environmental protection- should be an item not only in the concurrent list of schedule 7 to the Constitution but also in the list of matters entrusted to the panchayati institutions in the Schedule 11. It is heartening to note that so far as municipalities are concerned the Constitution of India lives up to the expectation. In the wake of New Industrial Policy based on liberalisation a long list of small scale industries fall outside the purview of environmental clearance. The Indian concept of environmental im»act assessment introduced under the Environment Act by notification excludes the entire gamut of small scale industries and r.elates only to scheduled industries covered by the notifica~ion. Most of them are subjected to ETA only it the investment goes above ~.50 crores. This provision dilutes the impact assessment considerably A mandatory impact assessment with public partiCipation and with provision for a review by specialized environmental courts will eliminate the possible evils of this judicial passiveness.

Social Justice and Weaker Sections: Role of the Judiciary

The Constitution of India. which has been described by an eminent writer as a "Corner stone of a nation". Has bestowed sufficient thought on the underprivileged. A number of provisions incorporated in it for their benefit tell the tale of statesmanship of the framers of the Constitution. for the vitality of a Constitution depends on the extent to which it affords protection to the under—priveleged. One such laudable provision in the Constitution relates to "weaker sections of the people", which has directed the State to promote with special care the educational and economic interests of such people. Besides. the Constitution has laid great stress on social justice. No comprehensive analysis in a single work seems to have been made so far of the connotations of social justice and the scope of the constitutional safeguards provided in favour of the weaker sections of the people. This thesis is the result of an attempt to analyse the connotations of social justice and the scope of the constitutional provisions made for the benefit of the weaker sections and the role played by the judiciary in this field The weaker sections, which are sought to be covered in this work, are "Backward C1asses". socially and educationally Backward Classes", "Scheduled Castes and Scheduled Tribes" and women. The first two categories of weaker sections have not been defined in the Constitution. So, their meaning and the criteria to determine them have to be gathered from the reports submitted by various Backward Class Commissions and judicial decisions rendered in a number of cases. The main thrust in this work is to understand the meaning and contents of social justice, identify the relevant weaker sections and to examine the extent to which the social justice has been rendered to the said weaker sections. The scope of this thesis is confined to the examination of the role of the judiciary in this field. So, the enquiry has been focussed mainly on the decisions of the judiciary bearing on the subject with a view to assessing the role of the judiciary in rendering social justice meaningful to the weaker sections in particular and to the Indian Society in general.

Customer perceptions of Banking Products and Services in Kerala with reference to Specific Customer Segments in the Urban Area

As of 1999. the state of Kerala has 3210 offices of scheduled commercial banks (SCBS). In all, there are 48 commercial banks operating in Kerala, which includes PSBs, OPBs, NPBS. FBs, and Gramin Banks. The urban areas give a complete picture of the competition in the present day banking scenario with the presence of all bank groups. Semi-urban areas of Kerala have 2196 and urban areas have 593 as on March 1995.“ The study focuses on the selected segments ofthe urban customers in Kerala which is capable of giving the finer aspects of variation in customer behaviour in the purchase of banking products and services. Considering the exhaustive nature of such an exercise, all the districts in the state have not been brought under the purview of the study. Instead. three districts with largest volume of business in terms of deposits, advances, and number of offices have been short listed as representative regions for a focused study. The study focuses on the retail customer segment and their perceptions on the various products or services offered to them. Non Resident Indians (NRIs), and Traders and Small—ScaIe Industries segments have also been included in the study with a view to obtain a comparative picture with respect to perception on customer satisfaction and service quality dimensions and bank choice behaviour. The research is hence confined to customer behaviour and the implications for possible strategies for segmentation within the retail segment customers

Accessing Education: Legal Perspectives

Access to education becomes an issue of equity with diverse claims from stakeholders justifying their rights based on perceptions of equity — both social and individual. In-spite of the phenomenal increase since independence in the number of institutions imparting education and the number of beneficiaries, India being the second largest nation in terms of population of the young finds its resources spread thin in meeting the demand for education. Quality education comes at a premium in India whether it is provided in the private or in the public sector. Education seemingly enables the individuals, singly and collectively. to overcome the social barriers perpetuated by the caste system. Taken together, these unleash grave demands on formulating equitable standards. It is in this context that identifying the deserving for favourable consideration becomes all the more important. In this sea of claims and counter-claims, this thesis tries to identify the issues involved on the question of equitable access to education on the basis of the factual position in the field of education. Identifying the issues correctly provides the necessary impetus for framing the questions that provide meaningful answers. The objective of this research is to help formulate the policy guidelines governing the principles of equity that is needed to ensure universal access to education in India.

Design And Development Of A Named Entity Based Question Answering System For Malayalam Language

This is a Named Entity Based Question Answering System for Malayalam Language. Although a vast amount of information is available today in digital form, no effective information access mechanism exists to provide humans with convenient information access. Information Retrieval and Question Answering systems are the two mechanisms available now for information access. Information systems typically return a long list of documents in response to a user’s query which are to be skimmed by the user to determine whether they contain an answer. But a Question Answering System allows the user to state his/her information need as a natural language question and receives most appropriate answer in a word or a sentence or a paragraph. This system is based on Named Entity Tagging and Question Classification. Document tagging extracts useful information from the documents which will be used in finding the answer to the question. Question Classification extracts useful information from the question to determine the type of the question and the way in which the question is to be answered. Various Machine Learning methods are used to tag the documents. Rule-Based Approach is used for Question Classification. Malayalam belongs to the Dravidian family of languages and is one of the four major languages of this family. It is one of the 22 Scheduled Languages of India with official language status in the state of Kerala. It is spoken by 40 million people. Malayalam is a morphologically rich agglutinative language and relatively of free word order. Also Malayalam has a productive morphology that allows the creation of complex words which are often highly ambiguous. Document tagging tools such as Parts-of-Speech Tagger, Phrase Chunker, Named Entity Tagger, and Compound Word Splitter are developed as a part of this research work. No such tools were available for Malayalam language. Finite State Transducer, High Order Conditional Random Field, Artificial Immunity System Principles, and Support Vector Machines are the techniques used for the design of these document preprocessing tools. This research work describes how the Named Entity is used to represent the documents. Single sentence questions are used to test the system. Overall Precision and Recall obtained are 88.5% and 85.9% respectively. This work can be extended in several directions. The coverage of non-factoid questions can be increased and also it can be extended to include open domain applications. Reference Resolution and Word Sense Disambiguation techniques are suggested as the future enhancements

Customary Laws of Lakshadweep Islands

The customary laws of Union Territory of Lakshadweep islands are a challenge for judicial institution as well as administrative machinery. With the peculiarities of socio-legal institutions, Lakshadweep system stands apart from the mainstream of legal systems in India. How far do the charismatic modernisation trends flowing into the Lakshadweep society affect the people already protected by the uncodified laws of the past? Many are the issues at this stage. This study analyses them. It examines the growth, evolution and development of the legal system in the islands vis-a-vis the administrative mechanism imposed by the mainland ethos and culture.

Automated Transcription System for Malayalam Language

Malayalam is one of the 22 scheduled languages in India with more than 130 million speakers. This paper presents a report on the development of a speaker independent, continuous transcription system for Malayalam. The system employs Hidden Markov Model (HMM) for acoustic modeling and Mel Frequency Cepstral Coefficient (MFCC) for feature extraction. It is trained with 21 male and female speakers in the age group ranging from 20 to 40 years. The system obtained a word recognition accuracy of 87.4% and a sentence recognition accuracy of 84%, when tested with a set of continuous speech data.
