Production of Alkaline Protease by Free and Immobilised Cells of VIBRIO sp. Under Different Fermentation Systems and Its Application on Deproteinisation of Prawn Shell Waste for Chitin Recovery

This thesis presents a detailed account of a cost - effective approach towards enhanced production of alkaline protease at profitable levels using different fermentation designs employing cheap agro-industrial residues. It involves the optimisation of process parameters for the production of a thermostable alkaline protease by Vibrio sp. V26 under solid state, submerged and biphasic fermentations, production of the enzyme using cell immobilisation technology and the application of the crude enzyme on the deproteinisation of crustacean waste.The present investigation suggests an economic move towards Improved production of alkaline protease at gainful altitudes employing different fermentation designs utilising inexpensive agro-industrial residues. Moreover, the use of agro-industrial and other solid waste substrates for fermentation helps to provide a substitute in conserving the already dwindling global energy resources. Another alternative for accomplishing economically feasible production is by the use of immobilisation technique. This method avoids the wasteful expense of continually growing microorganisms. The high protease producing potential of the organism under study ascertains their exploitation in the utilisation and management of wastes. However, strain improvement studies for the production of high yielding variants using mutagens or by gene transfer are required before recommending them to Industries.Industries, all over the world, have made several attempts to exploit the microbial diversity of this planet. For sustainable development, it is essential to discover, develop and defend this natural prosperity. The Industrial development of any country is critically dependent on the intellectual and financial investment in this area. The need of the hour is to harness the beneficial uses of microbes for maximum utilisation of natural resources and technological yields. Owing to the multitude of applications in a variety of industrial sectors, there has always been an increasing demand for novel producers and resources of alkaline proteases as well as for innovative methods of production at a commercial altitude. This investigation forms a humble endeavour towards this perspective and bequeaths hope and inspiration for inventions to follow.

Farm Programmes of Electronic Media: A Comparative Study of Audience Perception in Kerala

Farm communication and extension programs are vital part of the farm development attempts. Electronic media plays a major role in farm extension activities. Kerala, the consumer state, which was a complete agricultural state in pre-independence period, is the sprouting land of agricultural extension and publication activities in print media. Later AIR (All India Radio) farm programs and farm broadcasting of Doordarshan enriched the role of electronic media in farm extension activities. The media saturated southern state of India received this new electronic media farm communication revolution whole heartedly. However, after 1990, Kerala witnessed a flood of private T V channels and currently there are 24 channels in this regional language, named Malayalam. All major news and entertainment channels are broadcasting farm programs. Farm programs of AIR and Doordarshan, broadcasted in Malayalam language, have been well accepted to the farmers‘ in Kerala. However, post-independence period, witnessed the formation of Kerala state in Indian Union and the first ballot-elected communist Government started its administration. After the land reform bills, the state witnessed a gradual decrease in agricultural production. Even if it is not reflected much in the attitude and practices of farm community and farm broadcast of traditional electronic broadcasting, a change is observable after the post-liberalization era of India. Private Television channels, which were focused on entertainment value of programs, started broadcasting farm programs and the parameters of program production went through certain changes. In this situation, there is ample relevance for a study about the farm programs of electronic media in terms of a comparative study of audience perception. The study is limited in the state of Kerala as it is the most media saturated state in India. The study analyzes the rate, nature and scope of adoption of farming methods transmitted through electronic media (T.V. and Radio) in Malayalam language.All kinds of Farm programs including comprehensive program serials, success stories, seasonal cropping methods, experts opinion, been analyzed on the basis of the following objectives.  To find whether propagating new farm methods through farm programs in electronic media or the availability of adequate infrastructure and economic factors make a farmer to adopt a new farming method.  To find which electronic media has more influence on farmers to adopt agricultural programs.  To find which form of electronic media gets better feedback from farmers  To find out whether the programs of T.V. or Radio is more acceptable to farmers than the print media.  To find whether farmers gets the message through their preferred medium for the message. The researcher recorded opinions from a panel of agricultural officers, farm Information officers, agro extension researchers and experts. According to their opinions and guidelines, a pilot study is designed and conducted in Kanjikuzhy Panchayath, in Alappuzha district, Kerala. The Panchayath is selected by considering its ideal nature of being the sample for a social Science research. Besides, the nature of farming in the Panchayath, which devoid of the cultivation of cash crops also supported its sample value. As per the observations from the pilot study, researcher confirmed the Triangulation method as the methodology of research. The questionnaire survey, being the primary part contained 42 Questions with 6 independent and 32 dependent variables. The survey is conducted among 400 respondents in Idukki, Alappuzha and Pathanamthitta districts considering geographical differences and distribution of different types of crops. The response from a total of 360 respondents, 120 from each district, finally selected for tabulation and data analysis.The data analysis, based on percentage analysis, along with the results from focus group discussion among a selected group of 20 farmers, together produced the results as follows. Farmers, who are the audience of farm programs, have a very serious approach towards the medium. They are maintaining a critical point of view towards the content of the programs. Farmers are reasonably aware about the financial side of the programs and the monitory aspirations of both private and Government owned Television channels. Even though, the farmers are not aware on the technical terminology and jargons, they have ideas about success stories, program serials and they are even informed about channels are not maintaining an audience research section like AIR. Though the farmers accept Doordarshan as the credential source of farm information and methods, they are inclined to the entertainment value of programs too. They prefer to have more entertainment value for the programs of Doordarshan. Surprisingly, they have very solid suggestions on even about the shots which add entertainment value to the farm broadcasting methods of Doordarshan. Farmers are very much aware about the fact that media is just an instrument for inspiration and persuasion. They strongly believe that the source of information and new methods is agricultural research and an effective change happens only when there are adequate infrastructure and marketing facilities, along with the proper support from Government agricultural guideline and support systems like Krishi Bhavans. They strongly believe that media alone cannot create any magic in increasing agricultural production. Farmers are pointing out the lack of response to the feedback and queries of farmers on farming methods, as an evidence for the difference in levels of commitment of Government and private owned Television channels.Farmers are still perceiving AIR farm programs are far more committed to farmers and farming than any other electronic medium. However, they are seriously lacking Radio receivers with medium wave reception facility. Farmers perceive that the farming methods on new crops are more adoptable than the farming methods of traditional crops in both private and Government owned Television channels. There are multiple factors behind this observation from farmers. Farmers changed in terms of viewing habits and they prefer success stories, which are totally irrelevant and they even think that such stories encourage people to go for farming and they opined that such stories are good sources of inspiration. However, they are all very much sure about the importance and particular about the presence of entertainment factor even in farm programs. Farmers expect direct interaction of any expert of the new farming method to implement the method in their agriculture practices. Though introduction of a new idea in the T.V. is acceptable, farmers need the direct instruction of expert on field to start implementing the new farming practices Farmers still have an affinity towards print media reports and agricultural pages and they have complaints to print media on the removal of agricultural information pages from news papers. They prefer the reports in print media as it facilitates them to collect and refer articles when they need it. Farmers are having an eye of doubt about the credibility of farm programs by private T.V. channels. Even if they prefer private Television channels for listening and adopting new farming methods and other farm information, they scrutinize programs to know whether they are sponsored programs by agrochemical or agro-fertilizer manufacturer.

A Comparative Study Of The Organisation And Management Of Notihed Markets In Bangladesh With The Organisation And Management Of Regulated Markets In West Bengal India

For improving agricultural marketing, which has been discussed in the previous chapter, the Government has intervened in different ways. The direct regulatory role through the regulation of markets and market practices is one of the ways in which governmental intervention can improve agricultural marketing. This study is an enquiry of the direct regulatory role of the government through regulation of markets and market practices. By restructuring the operational methods and redesigning the existing physical markets, this system gives direct benefit to the cultivating class and protects them from the market manipulations of organised and powerful private traders. If traders do not continue their trade for the time being they will not be affected financially, because they are resourceful or financially solvent. On the other hand, Cultivators must sell their produce immediately after harvesting for the lack of additional facilities or to satisfy other needs for which finance is required. Another important reason is that Cultivators/farmers are not organised and because of lack of their organisation, they sell their produces individually. In this situation, a farmer is helpless when astute traders indulge in manipulations at the time of purchase of the produces. So it is the government's obligation to protect the interest of the farmers. Protection of the farmer/cultivator is necessary not only from the point of social justice but also from that of economic growth. If the farmers are assured of a remunerative or incentive price for their produce, they will get the inspiration to produce more and through more production, economy will be developed and the nation as a whole will be benefitted. This study will examine the management system of the markets through the direct regulatory role played by the governments to control markets and market practices in West Bengal and Bangladesh.

Continuation and discontinuation of local institution in community based natural resource management

Currently the push toward frontier areas, which until twenty years ago were still largely untouched by commercial agriculture, is taking place on a massive scale. This push is being driven not the least by global economic developments, such as the price increase of agriculture commodities like coffee and cocoa. In most cases the indigenous communities become trapped between the state monopoly in natural resource management and the competition for resources by external actors. In this processes the indigenous communities start to lose their access to resources. Another victim in this process is the environment where the natural resources are imbedded. International and national organizations working to conserve environment have became conscious of the important role that indigenous people could fulfill as partners in this endeavour. This partnership in struggle has produced a new discourse on the relationship between indigenous people and their environment. As a further consequence, programs were set up to develop what became known as Community Based Natural Resource Management (CBNRM) with its numerous variations. Based on a case study in a village on the eastern border of the Lore Lindu National Park in Central Sulawesi, this study questioned the basic assumption behind the concept of Community Based Natural Resource Management (CBNRM). Namely the assumption that communities living at the margin of forest are socially and culturally homogenous, still more or less egalitarian, and basically living in harmony with their natural environment. This study was inspired by the persistent critique – although still a minority – on the basic assumption the CBNRM from academicians and practitioners working through the Entitlement perspective. Another inspiration was the mounting critique toward the participatory approach. In its effort the study explore further the usefulness of certain approaches. One of the approach much relied on in this study was the local history of the community studied, through exerting oral and local written documents on local history, legends and local stories. These sources proofed quite capable in bringing the local history into the light. Another was the actor oriented approach, which later came to be supported by the concept of Social Pool Resources. The latter concept proofed to be useful as analytical instrument to integrate social institutions and the common pool resources, as a field of action for the different actors as human agencies.

De la désorganisation à l’organisation apprenante en milieu rural

ZUSAMMENFASSUNG Von der „Chaosgruppe“ zur lernenden Organisation. Fallstudien zur Induzierung und Verbreitung von Innovation in ländlichen Kleinorganisationen im Buruli (Zentral-Uganda). Die oft fehlende Nachhaltigkeit landwirtschaftlicher Projekte in Afrika allgemein und in Buruli (Zentral-Uganda) insbesondere gab den Anstoß zu der Forschung, die der vorliegenden Dissertation zugrunde liegt. Ein häufiger Grund für das Scheitern von Projekten ist, dass die lokale Bevölkerung die landwirtschaftliche Innovation als Risiko für die Ernährungssicherheit der Familie betrachtet. Die vorliegende Arbeit ist daher ein Beitrag zur Suche nach einem Weg zur Nachhaltigkeit, der dieser Tatsache Rechnung trägt. Als Forschungsmethode wurden die Gruppendiskussion und die Beobachtung mit den beiden Varianten „teilnehmender Beobachter“ und „beobachtender Teilnehmer“ gemäß Lamnek(1995b) angewendet. Es stellte sich heraus, dass die ablehnende Haltung der Zielbevölkerung landwirtschaftlicher Innovation gegenüber durch finanzielle Anreize, Seminare oder die Überzeugungskunst von Mitarbeitern der Entwicklungsorganisationen kaum behoben werden kann, sondern nur durch den Einbezug der Menschen in einen von ihnen selbst gesteuerten Risikomanagementprozess. Die Prozessberatung von Schein (2000) und die nichtdirektive Beratung von Rogers (2010) haben sich im Rahmen unserer Untersuchung für die Motivierung der Bevölkerung für eine risikobewusste Entwicklungsinitiative von großem Nutzen erwiesen ebenso wie für die Beschreibung dieses Prozesses in der vorliegenden Studie. Die untersuchten Gruppen wurden durch diesen innovativen Ansatz der Entwicklungsberatung in die Lage versetzt, das Risiko von Innovation zu analysieren, zu bewerten und zu minimieren, ihre Zukunft selbst in die Hand zu nehmen und in einem sozialen, ökonomischen und physischen Umfeld zu gestalten sowie auf Veränderungen im Laufe der Umsetzung angemessen zu reagieren. Der Erwerb dieser Fähigkeit setzte eine Umwandlung einfacher Bauerngruppen ohne erkennbare Strukturen in strukturierte und organisierte Gruppen voraus, die einer lernenden Organisation im ländlichen Raum entsprechen. Diese Transformation bedarf als erstes eines Zugangs zur Information und einer zielorientierten Kommunikation. Die Umwandlung der Arbeitsgruppe zu einer lernenden Bauernorganisation förderte die Nachhaltigkeit des Gemüseanbauprojekts und das Risikomanagement und wurde so zu einem konkreten, von der Umwelt wahrgenommenen Beispiel für die Zweckmäßigkeit des oben beschriebenen Forschungsansatzes. Die Herausbildung einer lernenden Organisation ist dabei nicht Mittel zum Zweck, sondern ist selbst das zu erreichende Ziel. Die Beobachtung, Begleitung und Analyse dieses Umwandlungsprozesses erfordert einen multidisziplinären Ansatz. In diesem Fall flossen agrarwissenschaftliche, soziologische, linguistische und anthropologische Perspektiven in die partnerschaftlich ausgerichtete Forschung ein. Von der Entwicklungspolitik erfordert dieser Ansatz einen neuen Weg, der auf der Partnerschaft mit den Betroffenen und auf einer Entemotionalisierung des Entwicklungsvorhabens basiert und eine gegenseitige Wertschätzung zwischen den Akteuren voraussetzt. In diesem Prozess entwickelt sich im Laufe der Zeit die „lernende“ Bauernorganisation auch zu einer „lehrenden“ Organisation und wird dadurch eine Quelle der Inspiration für die Gesamtgesellschaft. Die Nachhaltigkeit von ländlichen Entwicklungsprojekten wird damit maßgeblich verbessert.

Variación de volumen sistólico como predictor de hipovolemia en pacientes pediátricos con choque séptico

El compromiso del sistema cardiovascular es frecuente en los pacientes en estado crítico, por tanto la monitorización hemodinámica es esencial para un tratamiento apropiado dirigido a objetivos terapéuticos en este grupo de pacientes. La monitorización hemodinámica del gasto cardíaco y la estimación del volumen intravascular son fundamentales para el manejo de los pacientes pediátricos en estado crítico, la medición del gasto cardíaco es uno de los principales elementos para evaluar la situación hemodinámica y la perfusión tisular de un paciente ayudando a dirigir el tratamiento y a monitorizar la respuesta clínica en pacientes con choque séptico. La hipovolemia es una causa común para la falla circulatoria en pacientes en condición crítica, el encontrar un método confiable para medición de precarga es importante para guiar la administración de líquidos. Tradicionalmente se han utilizado medidas de la volemia asociadas como la presión venosa central (PVC), frecuencia cardiaca (FC), presión arterial (PA) y el gasto urinario. Estos indicadores tienen grandes factores de distracción que hacen que su valor sea limitado y por tanto se tengan que buscar alternativas más confiables. En años recientes se han postulado parámetros dinámicos para la evaluación de la precarga, entre ellos uno de los mas ampliamente estudiado es la medición de la variabilidad de Volumen sistólico (VVS); Este valor se basa en el concepto de que durante la inspiración, la disminución del retorno venoso produce una disminución del Volumen sistólico, lo cual se manifiesta como una disminución en la onda de pulso; Por tanto en una situación de hipovolemia esta diferencia será mayor, dado que será más evidente la disminución del volumen al final de la diástole. En adultos este parámetro se ha convertido en una herramienta útil para evaluar estado de volumen de los pacientes que se encuentran en estado crítico y ha demostrado su utilidad para predecir respuesta a administración de fluidos en diferentes poblaciones de pacientes. En la actualidad no hay estudios en niños que comparen la medición de VVS contra dichas medidas tradicionales de volemia.

Comparación de la presión del manguito del tubo orotraqueal estimada por palpación frente a la medición tomada con un manómetro

La presión que ejerce el manguito del tubo orotraqueal (TOT) sobre la mucosa al ser insuflado debe mantenerse en un rango de seguridad que evite complicaciones por sobreinflación o por desinsuflación. En nuestro medio, los instrumentos de medición objetiva no son de uso común. Objetivo: evaluar la concordancia de la presión del manguito del TOT estimada por palpación frente al uso de un manómetro manual en pacientes adultos sometidos a anestesia general. Materiales y métodos: se realizó un estudio de corte transversal que incluyó a 40 pacientes, a quienes, una vez intubados, dos anestesiólogos enmascarados, diferentes al que los intubó, palparon el manguito del TOT categorizándolo como sobreinflado, normal o desinflado; posteriormente, uno de los investigadores registró la medida con un manómetro en fase inspiratoria y espiratoria. Se consideró como rango normal de 20 a 30 cm H2O. Resultados: la concordancia de la estimación por palpación entre los dos anestesiólogos fue débil (Kappa = 0,21, ES: 0,11). La concordancia entre la estimación por palpación y la medición con el manómetro manual fue muy débil. Entre el primer anestesiólogo y el investigador en fase inspiratoria, . 0,08 (ES: 0,09), y en espiración, . 0,08 (ES: 0,07). Entre el segundo anestesiólogo y el investigador, . 0,05 (ES: 0,07) y 0,02 (ES: 0,06), respectivamente. Conclusión: el estudio muestra que la concordancia entre los métodos subjetivo y objetivo para determinar si el manguito del TOT está adecuadamente inflado fue débil. Se sugiere el empleo de métodos más objetivos para su determinación.

Bioinspired iron and manganese catalysts for the effective and selective oxidation of alkanes and alkenes

La gran eficiència, selectivitat i les condicions suaus exhibides per les reaccions que tenen lloc al centre actiu de les metal·looxigenases són la font d'inspiració per la present dissertació. Amb l'objectiu de dissenyar catalitzadors d'oxidació eficients hem fet ús de dues estratègies: la primera consisteix en el disseny de complexos amb baix pes molecular inspirats en aspectes estructurals de la primera esfera de coordinació del centre metàl·lic d'enzims de ferro i de manganès. Aquests complexos s'han estudiat com a catalitzadors en l'oxidació selectiva d'alcans i d'alquens fent servir oxidants "verds" com ara l'H2O2. La segona estratègia està basada en l'ús de la química supramolecular per tal de desenvolupar estructures moleculars auto-acoblades amb la forma i les propietats químiques desitjades. Concretament, la construcció de nanocontenidors amb un catalitzador d'oxidació incrustat a la seva estructura ens permetria dur a terme reaccions més selectives, tal com passa en les reaccions catalitzades per enzims.

O2 activation at bioinspired complexes: dinuclear copper systems and mononuclear non-heme iron compounds. Mechanisms and catalytic applications in oxidative transformations

L'activació d'oxigen que té lloc en els éssers vius constitueix una font d'inspiració pel desenvolupament d'alternatives als oxidants tradicionals, considerats altament tòxics i nocius. En aquesta treball s'utilitzen compostos sintètics com a models del centre actiu de proteïnes dinuclears de coure i mononuclears de ferro de tipus no-hemo que participen en l'activació d'oxigen en els éssers vius. Els sistemes dinuclears de coure mostren un centre de tipus coure(III) bis(oxo) que és capaç de dur a terme l'ortho-hidroxilació de fenols de manera similar a la reacció que catalitza la proteïna tirosinasa. Per altra banda, els sistemes de ferro desenvolupats en aquest treball actuen com a models de les dioxigenases de Rieske i poden dur a terme l'hidroxilació estereoespecífica d'alcans i l'epoxidació i cis-dihidroxilació d'olefines utilitzant peròxid d'hidrogen com a agent oxidant. Tot plegat demostra que el desenvolupament de sistemes model constitueix una bona estratègia per l'estudi dels sistemes naturals.

Theoretical studies of systems of biochemical interest containing Fe and Cu transition metals

La presència de la química teòrica i computacional està augmentant en quasi tots els camps de la recerca en química. Els càlculs teòrics poden ajudar a entendre millor l'estructura, les propietats i la reactivitat de compostos metàl·lics d'àrees tan diferents com la química inorgànica, organometàl·lica i bioinorgànica. No obstant això, és imprescindible utilitzar la metodologia adequada per obtenir resultats teòrics fiables. Els estudis d'aquesta tesi es poden dividir en dos grups diferents. El primer grup inclou l'estudi teòric del mecanisme de reacció de diversos sistemes que contenen coure i tenen diferents estructures Cun-O2. Aquests estudies s'han dut a terme amb l'objectiu de profunditzar en la natura dels processos oxidants químics i biològics promoguts per sistemes que contenen coure. En la segona part de la tesi, s'estudia la fiabilitat de diferents tècniques utilitzades per estudiar l'estructura electrònica i la reactivitat de sistemes que contenen coure, ferro i altres metalls de transició.

Edificio Lúdico de livre utilização: anti-edificio contemporâneo

A presente dissertação centra-se num estudo sobre, a conceção de um edifício lúdico, de utilização livre, sendo o projeto uma proposta atualizada e contemporânea de um edifício, relativamente utópico, que encontra no Fun Palace de Cedric Price o seu melhor antecedente. Apresenta-se uma breve referência a dois espaços sociais que sofreram influência deste anti edifício: o centro George Pompidou em Paris e Jaaga, na India. Os dois casos de estudo aqui apresentados, Downtowm Athletic Club em Nova Iorque e o pavilhão da Holanda em Xangai, revelam características relacionadas com o tema do dissertação – liberdade no espaço lúdico e enquanto locais onde o mote da sexualidade é integrado. O projeto resulta da análise das evoluções sofridas, desde 1960, no que diz respeito aos novos conhecimentos científicos que vieram contribuir para a geração de novas formas de apropriação de conceitos como é o caso do conceito da liberdade em espaços públicos e o da sexualidade. O conceito da sexualidade que evolui com os avanços que as neurociências atingem sobre o conhecimento do cérebro e das emoções e que se traduzem em novas demandas do viver contemporâneo

Cual los imbéciles, buscando un bastón (En torno al enmarañado viaje de Henri Michaux al Ecuador)[Estudio]

En Ecuador. Journal de Voyage (1929) Henri Michaux quisiera ir más allá del vértigo del vacío y de la nada, dar con los significados que se le escapan, dar quizás con lo “transreal”. Con esa lente, y teniendo en cuenta el contexto histórico e ideológico, hay que entrar en la relación del autor belga-francés a lo largo del Atlántico, por la región andina ecuatoriana, y por la Amazonía. Por eso vale ilustrar, aunque sea tangencialmente, la práctica literaria que caracteriza esa obra para no hacer de ella un mero reportaje de viaje cuando, en efecto, se trata de un libro de exigente lectura, de un esfuerzo, por no decir de un tratado, de inspiración poética, teórica, que responde a una estética y a un diseño, a una estilizada y hasta sistemática cosmovisión. Las analogías y yuxtaposiciones de inspiración vanguardista entregan un mundo en que coinciden, estallan y contrastan lo exterior y lo interior, lo dinámico y lo estático, lo cotidiano y lo extraño, lo íntimo y lo vasto, lo sagrado y lo profano, lo limitado y lo infinito. Palabras clave: Henri Michaux, viaje, búsqueda, historia, Ecuador/ecuador, Europa, Atlántico, Andes, Amazonía, yuxtaposición, contraste, analogías, espacio, viviendas rústicas, música, remedos, límites, borroso, infinito.

Memory-based Embodied Cognition: a computational architecture

At its most fundamental, cognition as displayed by biological agents (such as humans) may be said to consist of the manipulation and utilisation of memory. Recent discussions in the field of cognitive robotics have emphasised the role of embodiment and the necessity of a value or motivation for autonomous behaviour. This work proposes a computational architecture – the Memory-Based Cognitive (MBC) architecture – based upon these considerations for the autonomous development of control of a simple mobile robot. This novel architecture will permit the exploration of theoretical issues in cognitive robotics and animal cognition. Furthermore, the biological inspiration of the architecture is anticipated to result in a mobile robot controller which displays adaptive behaviour in unknown environments.

Introduction

Lying at its core, antiquity has saturated Western culture so thoroughly as to be present everywhere, and it is continually revealing itself in new ways. The aspects of the ancient world which we imitate, ridicule, fantasise about, shudder at or privilege tell us who we are—as they always have. As long as our culture continues to evolve, there will always be new things to be learned about its ancient Greek and Roman heritage. Classics For All invites both academic (from a variety of disciplines) and non-academic readers to take a fresh look at the ancient world as inspiration in mass culture.
