Full textAbstract:
In the last years, the European countries have paid increasing attention to renewable sources and greenhouse emissions. The Council of the European Union and the European Parliament have established ambitious targets for the next years. In this scenario, biomass plays a prominent role since its life cycle produces a zero net carbon dioxide emission. Additionally, biomass can ensure plant operation continuity thanks to its availability and storage ability. Several conventional systems running on biomass are available at the moment. Most of them are performant either in the large-scale or in the small power range. The absence of an efficient system on the small-middle scale inspired this thesis project.
The object is an innovative plant based on a wet indirectly fired gas turbine (WIFGT) integrated with an organic Rankine cycle (ORC) unit for combined heat and power production. The WIFGT is a performant system in the small-middle power range; the ORC cycle is capable of giving value to low-temperature heat sources. Their integration is investigated in this thesis with the aim of carrying out a preliminary design of the components. The targeted plant output is around 200 kW in order not to need a wide cultivation area and to avoid biomass shipping.
Existing in-house simulation tools are used: They are adapted to this purpose. Firstly the WIFGT + ORC model is built; Zero-dimensional models of heat exchangers, compressor, turbines, furnace, dryer and pump are used. Different fluids are selected but toluene and benzene turn out to be the most suitable. In the indirectly fired gas turbine a pressure ratio around 4 leads to the highest efficiency. From the thermodynamic analysis the system shows an electric efficiency of 38%, outdoing other conventional plants in the same power range. The combined plant is designed to recover thermal energy: Water is used as coolant in the condenser. It is heated from 60°C up to 90°C, ensuring the possibility of space heating.
Mono-dimensional models are used to design the heat exchange equipment. Different types of heat exchangers are chosen depending on the working temperature. A finned-plate heat exchanger is selected for the WIFGT heat transfer equipment due to the high temperature, oxidizing and corrosive environment. A once-through boiler with finned tubes is chosen to vaporize the organic fluid in the ORC. A plate heat exchanger is chosen for the condenser and recuperator.
A quasi-monodimensional model for single-stage axial turbine is implemented to design both the WIFGT and the ORC turbine.
The system simulation after the components design shows an electric efficiency around 34% with a decrease by 10% compared to the zero-dimensional analysis. The work exhibits the system potentiality compared to the existing plants from both technical and economic point of view.

Woodcock, Frederick C. "Use of a knelson unit to quantify gravity recoverable gold in an ore." Thesis, McGill University, 1994. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=55416.
Full textAbstract:
A method to determine the amount of gravity recoverable gold in an ore sample with a 7.5 cm (3 inch) Knelson Centrifugal Concentrator is presented. The method is based on sequential comminution and recovery steps, the first at 100% $-$841 $ mu$m, the second at approximately 50% $-$74 $ mu$m and the third at final grind (typically 75 to 90% $-$74 $ mu$m). The mass processed depends on the gold grade and particle size, and commonly varies from 25 to 100 kg.The method was used to determine the gravity recoverable gold in nine different ore samples. The grade of these ores ranged from 3 g/t to 45 g/t. Both massive sulfide and silicate ores were tested. Gold in the ores ranged from fine (90% $-$210 $ mu$m) to coarse (60% +841 $ mu$m). The amount of gravity recoverable gold ranged from 29 to 93%. Results from the proposed test compare favorably with mineralogical studies and data from industrial gravity recovery circuits. Some problems arose while testing the various ores; minor adjustments to the procedure were made to correct these. These corrections and other caveats for the test procedure are discussed.
This test yields an essential component of an algorithm that can be used to predict the amount of gold that can be recovered by installing a gravity circuit. This algorithm is referenced and an example of its use is included. Information from the test can be used to evaluate circuit performance and indicate if the performance is equipment or process limited. The test will quickly indicate if a gravity circuit is an option.
Results indicate that sizing material before it is processed with a Laboratory Knelson Concentrator leads to significant increases in recovery (48% without screen to 64% with). Industrial results are not yet available to verify this.

Full textAbstract:
Le conflit agricole entre les Etats-Unis et l'Europe demeure le conflit le plus récurrent au sein du GATT et de l'OMC. Afin de comprendre pourquoi, une étude préliminaire permet de constater que l'agriculture est un secteur très sensible, à tel point que même les Etats-Unis acquis aux thèses libérales doivent soutenir ce secteur. Apparait donc un antagonisme entre l'obligation imposée par le GATT de libéraliser le commerce et la nécessité de maintenir les politiques agricoles. Au sein du GATT, les Etats-Unis parviennent à exempter leur agriculture de la libéralisation, mais ouvrent les hostilités à l'encontre de la CEE et de la PAC en 1962. Le conflit entamé à cette époque existe encore aujourd'hui. En dépit des nouvelles règles établies à l'issue de l'Uruguay round, les conflits traités au sein de l'OMC deviennent plus complexes : des questions touchant à l'intérêt général et à la souveraineté des Etats sont apparues rendant la tâche de l'Organe de règlement des différends plus ardueThe agricultural conflict between Europe and the United States remains the most persistent conflict within the GATT and the WTO. So as to understand why, a preliminary study testifies that agriculture is a very sensitive sector, so that even the United States had to support it, in spite of their liberal convictions. Arises then an antagonism between the GATT obligation to liberalise trade and the duty to preserve agricultural policies. Within the GATT, the United States are allowed to exempt their agriculture from the obligation of liberalisation, but start to struggle against the EEC and the CAP in 1962. The conflict that started then is still existing nowadays. Despite the new rules established after the Uruguay Round, the agricultural conflicts within the WTO are multifaceted : the dispute settlement Body has to deal with more complex questions concerning general interest and States' sovereignty

Full textAbstract:
This master's thesis evaluates data annotation, semantic segmentation and Docker for use in AWS. The data provided has to be annotated and is to be used as a dataset for the creation of a neural network. Different neural network models are then to be compared based on performance. AWS has the option to use Docker containers and thus that option is to be examined, and lastly the different tools available in AWS SageMaker will be analyzed for bringing a neural network to the cloud. Images were annotated in Ilastik and the dataset size is 276 images, then a neural network was created in PyTorch by using the library Segmentation Models PyTorch which gave the option of trying different models. This neural network was created in a notebook in Google Colab for a quick setup and easy testing. The dataset was then uploaded to AWS S3 and the notebook was brought from Colab to an AWS instance where the dataset then could be loaded from S3. A Docker container was created and packaged with the necessary packages and libraries as well as the training and inference code, to then be pushed to the ECR (Elastic Container Registry). This container could then be used to perform training jobs in SageMaker which resulted in a trained model stored in S3, and the hyperparameter tuning tool was also examined to get a better performing model. The two different deployment methods in SageMaker was then investigated to understand the entire machine learning solution. The images annotated in Ilastik were deemed sufficient as the neural network results were satisfactory. The neural network created was able to use all of the models accessible from Segmentation Models PyTorch which enabled a lot of options. By using a Docker container all of the tools available in SageMaker could be used with the created neural network packaged in the container and pushed to the ECR. Training jobs were run in SageMaker by using the container to get a trained model which could be saved to AWS S3. Hyperparameter tuning was used and got better results than the manually tested parameters which resulted in the best neural network produced. The model that was deemed the best was Unet++ in combination with the Dpn98 encoder. The two different deployment methods in SageMaker was explored and is believed to be beneficial in different ways and thus has to be reconsidered for each project. By analysis the cloud solution was deemed to be the better alternative compared to an in-house solution, in all three aspects measured, which was price, performance and scalability.

Full textAbstract:
The analysis carried out in this thesis is made from two different points of view, the qualitative and the quantitative, by using the case study of Malmö intermodal terminal. The first analysis is focused on how the intermodal terminals works and which elements of it interact and how, in order to achieve the purpose of the terminal, and how the Intelligent Video Gate is able to affect in any way to this functioning, mainly in a positive way that allows the better functioning of the terminal.From the quantitative point of view what is carried out is a timing and economic analysis of the Malmö Intermodal Terminal, which is based on the information obtained from the qualitative analysis and from the data provided by the terminal operators that allow to make different simulations to compare the effect of the Intelligent Video Gate implementation in this specific terminal, and that could be extended to similar intermodal terminals located in regions with similar labour conditions and that as the European Union have a huge standardized freight system.Finally, what is stated with the provided data, despite not allowing to make the most complex and representative simulation, is that the aim of the Intelligent Video Gate is reached successfully with a great improvement of the efficiency what allows to ensure with quite certainty that the system implementation is recommended in this kind of terminals.

Full textAbstract:
The motivation for this investigation into microturbine and desalination processes is the desire to combat problems caused by frequent high temperature conditions related to the spread of global warming. The small-scale power microturbine C200, designed by the Capstone Co., was chosen. Also, a single effect absorption chiller was employed in this study. The method of thermal vapor compression multi-effect distillation desalination was chosen as a potable water producer. Also, the organic Rankine cycle was powered by low-grade heat energy. Each model was simulated and investigated on a stand-alone basis under ISO conditions using off-design simulations. The ORC, absorption chiller and TVC-MED desalination process were separately driven with the same amount of fuel consumption into microturbine. All the base and proposed models were simulated by using a software package called IPSEpro. The economic accessibility and profitability of all the proposed models was examined. Integrating the microturbine with the ORC unit led to the generation of an extra 4.10% of electric power compared to that produced by the absorption chiller, and 7.80% for TVC-MED desalination. However, the lowest carbon emission rate for all models was achieved by using a microturbine with TVC-MED desalination with a reduction of 46.80%. Accordingly, the EUF of the TVC-MED desalination was 9.20% higher than when an absorption chiller was used, and 42.40% higher than when ORC was used. ORC gained the lowest EUF. The higher rate of exergetic efficiency was found when utilising the microturbine with the single effect absorption chiller with a value of 31.00%, as compared to ORC and TVC-MED, which registered rates of 23.11%, and 22.42% respectively. The results of economic study showed that, if the selling price was £0.023/kWh, then the profitability evaluation results would not be attractive for investment. However, if investment was made into a microturbine, then the electricity price could be set at £0.040/kWh or £0.060/kWh, resulting in a desirable economic feasibility for all combined models.

Full textAbstract:
Las recuperaciones de oro y plata no siempre reflejan, los niveles de recuperación logrados en las pruebas metalúrgicas del estudio de factibilidad del proyecto. Las Auditorias del circuito de Flotación nos confirman que la mayoría de pérdidas están en las mallas finas. También se observa una concentración de oro y plata en el circuito de molienda secundaria. Pruebas de mineralogía, flotación flash y gravimetría coinciden en la conclusión de que existe una porción del oro y la plata en el mineral que se comporta como GRG (oro recuperable por gravimetría). La implementación de un proceso que recupere este oro que recircula; incrementaría la recuperación de oro que se esta obteniendo actualmente. Para ello existen 2 procesos probados: la Gravimetría mediante un concentrador centrífugo (Falcón) y la Flotación Flash. La flotación Flash solo ha sido probado a nivel de laboratorio, obteniendo recuperaciones de 88.4% de este oro que recircula, el cual es un resultado muy superior a la gravimetría de 27.57% del oro recirculante, la siguiente etapa es mediante una prueba piloto de la Flotación Flash para confirmar el resultado obtenido a nivel de laboratorio. Debido a que no se cuenta con la celda de pilotaje; para estimar este incremento se realizo un programa de simulación matemática con el método de recuperaciones parciales para predecir su efecto. El costo total de instalación de un circuito de flotación flash, seria de 54 611 US$, lo cual se paga con tan solo el 1% de mejora en la recuperación de oro durante 3.5 meses. Se espera una mejora mayor del 2% de recuperación de oro. La simulación determino un incremento de hasta 92% en plata y a 95.1 en oro, dependiendo de la carga circulante del oro. Por varios motivos detallados en este presente trabajo, se concluye que la recuperación de oro y plata puede ser incrementada con la instalación de un equipo Skim Air de Outokumpu. La mejora mínima del 1%, en la recuperación de oro significa un ingreso de 16295 dólares mensuales, los resultados de la Flotación Flash a nivel laboratorio indican una mejora mayor al 2 y 3%.

International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, NevadaThe Remote Unit (RU) for a decentralised on-board base-band telemetry system is designed for use in launch vehicle missions of the Indian Space Research Organisation (ISRO). This new design is a highly improved and miniaturised version of an earlier design. The major design highlights are as follows. Usage of CMOS Field Programmable Gate Array (FPGA) technology in place of LS TTL devices, the ability to acquire various types of data like high level single ended or differential analog, bi-level events and two channels of high speed asynchronous serial data from On-Board Computers (OBCs), usage of HMC technology for the reduction of discrete parts etc. The entire system is realised on a single 6 layer MLB and is packaged on a stackable modular frame. This paper discusses the design approach, tools used, simulations carried out, implementation details and the results of detailed qualification tests done on the realised qualification model.

Full textAbstract:
In Aotearoa New Zealand, M?ori are overrepresented in criminal and mental health contexts, comprising only 14.9% of the nation, yet over 50% of institutional populations. These figures are not unique, but represent a broader struggle to overcome the legacy of colonization affecting indigenous communities worldwide. In response to these issues, I examine the impacts of M?ori cultural expression in forensic mental health through an ethnography of the kapa haka r?p? (group) in the Kaupapa M?ori forensic psychaitric unit, Te Papak?inga O T?ne Whakapiripiri. This unit reconceptualizes Western frameworks for mental health service provision, incorporating cultural education as an integral aspect of treatment, such as M?ori performing arts (i.e., kapa haka). The unit also imbues M?ori cultural values, practices, and forms of expression into daily life, an act that transforms the experience of institutionalization for t?ngata whai i te ora (patients) and the practice of forensic mental health more broadly. In this dissertation, I first unpack the collaborative methodology developed in this research, providing a set of recommendations for a more ?codetermined? research process. I then explain the research?s broader academic and social contexts, tracing the history of M?ori music scholarship, and then the history of New Zealand?s cultural and political transformation from 1840 to the present. This culminates in an ethnography of T?ne Whakapiripiri, where I examine the impacts of the kapa haka program and the unit?s broader musical activities on t?ngata whai i te ora and the clinical environment in four domains: te taha wairua (the spirit), te taha hinengaro (the mind), te taha tinana (the body), and te taha wh?nau (the community). Overall, this research illustrates that embedding forms of cultural expression such as kapa haka into the clinical model positively impacts t?ngata whai i te ora, improving their understanding and experiences of themselves, their illnesses, and their environment. Such cultural expression also shows how a Kaupapa M?ori framework transforms the institutional environment from a Western model emphasizing individualism, hierarchy, and isolation toward a more holistic, collective, and wh?nau-centered model that holds the potential to shift our understanding of what forensic mental health is and can be.

Full textAbstract:
Several lipopeptidyl nucleoside antibiotics that inhibit bacterial translocase I (MraY) involved in peptidoglycan cell wall biosynthesis contain an aminoribosyl moiety, an unusual sugar appendage in natural products. A-90289 and muraminomicin are the two representative antibiotics that belong to this family. Bioinformatic analysis of the biosynthetic A-90289 gene clusters revealed that five enzymes are likely involved in the assembly and attachment of the aminoribosyl unit. These enzymes of A-90289 are functionally assigned by in vitro characterization. The results reveal a unique ribosylation pathway that highlighted by uridine-5′-monophosphate as the source of the sugar, a phosphorylase strategy to generate a sugar-1-phosphate, and a primary amine-requiring nucleotidylyltransferase that generates the NDP-sugar donor. Muraminomicin, which has a structure similar to A-90289, holds the distinction in that both ribose units are 2-deoxy sugars. The biosynthetic gene cluster of muraminomicin has been identified, cloned and sequenced, and bioinformatic analysis revealed a minimum of 24 open reading frames putatively involved in the biosynthesis, resistance, and regulation of muraminomicin. Similar to the A-90289 pathway, fives enzymes are still likely involved in the assembly of the 2,5-dideoxy-5-aminoribose saccharide unit, and two are now functionally assigned and characterized: Mra20, a 5′-amino-2′,5′-dideoxyuridine phosphorylase and Mra23, a UTP:5-amino-2,5-dideoxy-α-D-ribose-1-phosphate uridylyltransferase. The cumulative results are consistent with the incorporation of the ribosyl appendage of muraminomicin via the archetypical sugar biosynthetic pathway that parallels A-90289 biosynthesis

Full textAbstract:
L’intérêt pour la politique industrielle a fait un retour remarqué dans le contexte post consensus de Washington. Mais ce regain d’intérêt de la littérature survient dans un environnement international qui pose des défis majeurs pour la conduite de politiques industrielles. En effet, le mode dominant d'insertion dans l'économie mondiale au cours des trois dernières décennies a été celui de la libéralisation des comptes courants et de capitaux, réduisant les marges de manœuvre des gouvernements pour le choix et la conduite de politiques industrielles aussi bien de facto que de jure. La thèse procède à une évaluation qualitative et comparative des contraintes sur l’utilisation des instruments de la politique industrielle sur 36 Accords Commerciaux Régionaux de types Nord-Sud et Sud-Sud : 10 accords avec les États-Unis, 12 avec l’Union Européenne, 6 avec la Chine et 8 avec l’Inde. La thèse cartographie les engagements de ces accords qui influent sur les instruments de la politique industrielle dans trois domaines interdépendants : la régulation des investissements étrangers, les règles sur les brevets, et les règles relatives à la normalisation. Les résultats de cette étude établissent que les accords de type Nord-Sud dépassent systématiquement des engagements des accords de l’OMC, donc rétrécissent voire éliminent leurs flexibilités. En conséquence, l'espace de politique industrielle de jure des pays partenaires se rétrécit à un niveau historiquement bas. Alternativement, les modes de régulation de type Sud-Sud préservent, dans une large mesure, les flexibilités de l'OMC comme résultat de (i) l’affirmation explicite de ces flexibilités ; (ii) la non-inclusion des engagements substantiels allant au-delà des accords de l’OMC. Contrairement aux accords des États-Unis et de l’Union Européenne, la possibilité de jure d’utiliser les mesures de la politique industrielle est donc largement préservée dans le cadre des accords avec la Chine et l’Inde en ce qui concerne : (i) les mesures relatives à la régulation des investissements étrangers qui garantissent leur contribution au développement industriel, tout en évitant les risques associés à ce type d'investissement ; (ii) la mise en place d'un système national de brevet facilitant l’accès à et la diffusion des technologies et des connaissances ; (iii) l’utilisation des normes et des règlements techniques comme instruments pour surmonter les problèmes de coordination inefficiente des investissements, ainsi que comme mécanisme de contrôle accompagnant les différents soutiens apportés par l’État à la production localeLately, interests in industrial policy have made a remarkable comeback in an international environment that holds serious challenges as the integration into the wold economy that took the form of trade, investment, and financial liberalization, in last three decades, has reduced de facto and de jure industrial policy space.The thesis provides a qualitative and a comparative assessment of constraints on the use of industrial policy instruments in the context of the rising regionalism. It reviews 36 North-South and South-South regional trade agreements: 10 Agreements of the United States, 12 Agreements of European Union, 6 Chinese Agreements and 8 Indian Agreements, all with developing countries. It maps commitments that affect industrial policy instruments in three interrelated areas: foreign investment regulation, patent, and standardization. It compares the agreements’ engagements against WTO obligations and each other.Results show that North-South modes of regulation of investment and trade relations go systematically beyond WTO Agreements commitments, narrowing and eliminating its “flexibilities”. As a result, de jure industrial policy space of partner countries shrinks to a historically low level. In turn, the South-South modes of regulation of trade and investment relations preserve WTO “flexibilities” to a large extent, as result of (i) explicit affirmation of these flexibilities, and (ii) the non-inclusion of substantial commitments going beyond WTO agreements.Contrary to the agreements of the United States and the European Union, the de jure possibility to use industrial policy instruments is substantially preserved under the agreements of China and India with respect to: (i) measures aimed at regulating foreign investments in a manner that permits to trigger its industrial development benefits and to avoid its associated risks, (ii) the design of national patent system in manner that facilitates the access to and diffusion of technologies and knowledge, and (iii) the use of standards and technical regulations as instruments to overcome investment coordination failure, and as tools of control mechanism that should be associated with the State’s distributed rent to local producers

Full textAbstract:
Introduite en 1933 par Garrett Birkhoff, la théorie des treillis semble s’établir, en une quinzaine d’années, comme un domaine autonome des mathématiques, dont l’essor se situe dans un contexte de circulation de l’algèbre moderne aux États-Unis. Ce travail questionne l’apparition et le développement d’une théorie des treillis, ses liens avec l’algèbre moderne et le rôle de l’American Mathematical Society (AMS) dans ce processus. Après avoir problématisé la catégorie historiographique de théorie, nous envisagerons la théorie des treillis selon trois biais différents. Premièrement, nous l’aborderons à travers les articles de G. Birkhoff et Øystein Ore, souvent considérés comme fondateurs de la théorie. Ici, la théorie est un objet explicitement reconnu par les acteurs pour désigner et relier leurs travaux. Comme catégorie d’analyse, elle masque cependant leur diversité en les agrégeant sous une même dénomination non-problématisée. Deuxièmement, la théorie sera envisagée à une échelle plus large, à partir de publications de membres de l’AMS s’intéressant aux treillis. Elle apparaît alors comme un ensemble de pratiques partagées par un collectif de mathématicien·ne·s. Enfin, dans un dernier chapitre nous aborderons la promotion de la théorie des treillis au sein de l’AMS. Je tenterai de montrer qu’elle profite à la fois d’un statut d’« algèbre abstraite américaine » et des positions de ses promoteur·rice·s dans la sociétéIntroduced in 1933 by Garrett Birkhoff, Lattice Theory seems to settle, in about fifteen years, as an autonomous domain of mathematics, whose rise takes place in a context of circulation of modern algebra in the United-States. The current work questions the appearance and development of a theory of lattices, its links to modern algebra and the role of the American Mathematical Society (AMS) in this process. After problematizing the historiographical category of a theory, we will consider the theory of lattices through three different biases. First, we will approach it through the article of G. Birkhoff and Øystein Ore, often considered as founders for the theory. Here, the theory is an object explicitly identified by the actors to designate and link their works together. However, as an analytical category, it hides their diversity by joining them into a same non-problematized denomination. Secondly, the theory will be considered at a larger scale, from the publications of members of the AMS interested in lattices. From here, it appears as a set of practices shared by a collective of mathematicians. Finally, in a last chapter we will approach the promotion of Lattice Theory within the AMS. I will try to show that it benefits from both the status of an « american abstract algebra » and the positions of its promoters within the society

Full textAbstract:
La Politique de Cohésion (PC), principal instrument de la 'solidarité européenne', est en passe de devenir le premier poste budgétaire de l'Union Européenne (UE). Bien que précieuses, les théories économiques traditionnellement sollicitées pour éclairer cette politique sont insatisfaisantes, notamment car elles considèrent comme exogènes des facteurs politiques, institutionnels et organisationnels en réalité cruciaux. Nous construisons donc un schème d'interprétation politico-économique de la PC, qui souligne l'importance et l'enchaînement des décisions, des interactions entre acteurs, des processus décisionnels et du processus de politique, pour la physionomie de la PC. Notre étude empirique, outre qu'elle valide notre conception théorique de la PC et en enrichit la compréhension, montre que la phase de définition est déterminée par un impératif de stabilité politique plus que par un souci d'allocation optimale des ressources. Cela permet de mettre en exergue le rôle plus large joué par la PC dans le processus d'intégration européenne. Son caractère flexible fait d'elle un instrument efficace de prise des décisions relatives à l'approfondissement et à l'élargissement. Ensuite, bien que l'évaluation de la PC soit difficile, nous montrons que les décisions institutionnelles et organisationnelles ont un impact sur l'efficacité de la politique de cohésion à la phase de mise en oeuvre.

Full textAbstract:
L’objectif de la thèse est de comprendre dans quelle mesure le conflit entre l’Amérique du Nord et l’Europe sur l’utilisation d’hormones de croissance en élevage a participé à l’histoire institutionnelle de la régulation du commerce mondial de denrées alimentaires. Entre 1980 et la période contemporaine (2016), plusieurs épisodes critiques ont mis en évidence la perspective atypique de l’Union européenne à l’égard de l’emploi de ces médicaments vétérinaires ainsi que la contestation suscitée par cette réglementation spécifique dans le cadre de la mondialisation commerciale. Ce conflit se joue sur plusieurs scènes : au sein de la Communauté européenne qui, pendant la décennie 1980, peine à trouver un accord interinstitutionnel quant à une législation commune sur les hormones de croissance ; dans le cadre du General agreement on tariffs and trade (GATT) puis del’Organisation mondiale du commerce (OMC) ; et enfin au sein du Codex Alimentarius, l’organisation internationale chargée d’élaborer des normes alimentaires. Dans chacune de ces instances, la gestion du conflit coïncide avec une phase importante du point de vue institutionnel : création d’organes spécifiques, nouveaux principes et procédures de travail. Dès lors, notre travail visait à détailler l’impact éventuel du conflit sur les hormones de croissance sur chacune de ces institutions ainsi quesur la façon dont, globalement, elles participent à la régulation du commerce international dans le domaine agroalimentaire.Notre travail s’est appuyé sur une enquête socio-historique utilisant un matériau riche et varié permettant de couvrir l’ensemble des institutions identifiées sur la période 1980-2016 : un corpus documentaire a été constitué grâce aux archives des différentes institutions, une trentaine d’entretiens semi-directifs ont été menés. Enfin, plusieurs centaines d’heures d’observationethnographique ont pu être réalisées, la plupart grâce à notre statut de fonctionnaire française du ministère de l’agriculture. Il met en évidence l’évolutivité des fonctions remplies par le conflit sur les hormones de croissance : celui-ci a en premier lieu permis de fédérer l’ensemble des acteurs concernés de la nécessité de renforcer les institutions supranationales, que ce soit à l’échelon européen ou international. Il a ensuite participé à l’élaboration concrète des institutions en permettant d’en tester les instruments au fur et à mesure de leur création, et ainsi, de permettre de réaliser les ajustements jugés nécessaires. De ce point de vue, la gestion du conflit sur les hormones révèle la perception des relations internationales des différents acteurs et sa variabilité temporelle. Enfin, constituant un paramètre pérenne que les acteurs intègrent à leur stratégie de négociationinternationale, le conflit sur les hormones est devenu un point d’ancrage autour duquel s’est structurée une communauté. Il doit ainsi être considéré pour son potentiel socialisateur.Notre enquête apporte également des informations concernant les attentes d’un certain nombre d’acteurs privés en termes de régulation internationale. Le cas des hormones mobilise l’attention des grandes firmes pharmaceutiques qui poussent à l’établissement de normes internationales contraignantes pour le commerce de produits agricoles et concentrent plus particulièrement leur action sur les instances productrices de normes (comme le Codex Alimentarius). Ce comportement semble indiquer que ces acteurs utilisent les instruments de régulation mondiale pour la diffusion de principes d’action publiqueThe goal of this work is to understand how deep the commercial war between North America and Europe regarding the use of growth hormones in food-producing animals impacted institutional history of global food trade regulation. Between 1980 and the contemporary period (2016), several crises revealed the atypical nature of the European Union ban. As a result, the European Union views legitimacy was contested in the globalization context. The conflict takes places in several arenas. First of all, it constitutes an issue for Europe, which strived to find an interinstitutional agreement on how to legislate on growth hormones at the European level during the 80ies. Then, it has been one of the most talked about disagreements of the General agreement on tariffs and trade (GATT) and the World trade organization (WTO) negotiations from 1987 onwards. Finally, it involves the CodexAlimentarius Commission, the international organization in charge of setting food standards. In each of these institutions, the beef-hormones conflict management goes with important institutional changes: new specific units, working principles and procedures were created. Thus, my work aimed to precisely describe what consequences the beef-hormones conflict might have had on any of these institutions. As a result, I show how this specific case contributed to the instauration of internationalfood trade regulation.My work relies on a socio-historical inquiry based on diverse and rich empirical data, in order to cover the three aforesaid institutions between 1980 and 2016. I constituted a documentary corpus from institutional archives, and I performed about thirty sociological interviews. I spent several hundreds of hours realizing ethnographing observation, most of which being facilitated by my belonging to the ministry of agriculture’s services. Analysis of this data emphasizes the transforming role of the beef-hormones conflict at an international scale. The conflict first convinced all the stakeholders that it was crucial to strengthen supranational institutions (be it at the European or at the global level). It also allowed to test newly created instruments in their practical functioning. From this prospective, the beef-hormones conflict management reveals the different actors’ internationalrelations perceptions and their evolution during the studied period. Finally, as the beef-hormones conflict has constituted a pattern to the establishment of negotiation strategies, it became a cultural reference structuring an international community. It is therefore a socializing factor.My inquiry also enables a better understanding of private actors’ expectations about international regulation. Veterinary drug industries are actively involved in the institutional discussions surrounding the beef-hormones case, requesting for binding international food trade standards. They are more particularly interested in the activity of standard-setting bodies like Codex. This attitude indicates that those actors use global regulation instruments to advocate for their preferred collective action principles

Full textAbstract:
La réinitiation de la traduction est un mécanisme permettant de traduire des ORF qui sont présents dans la région leader de différents ARNm cellulaires (uORF). La majorité des cas de réinitiation de la traduction chez les eucaryotes concerne des uORF de petite taille. Des stratégies alternatives ont été développées, entre autres par les virus, afin de réinitier la traduction après un long uORF. Le virus de la mosaïque du chou-fleur (CaMV) exprime un ARNm polycistronique codant la totalité des protéines virales. L’une d’entre elle, la protéine TAV (TransActivateur/Viroplasmine) est un facteur essentiel qui rend possible la réinitiation de la traduction après de longs ORF et qui, de plus, active la protéine kinase TOR. La sous-unité h du facteur d’initiation de la traduction eIF3, requise pour promouvoir la reinitiation après un petit ORF chez les plantes, a été identifiée comme étant une nouvelle cible de phosphorylation de la voie de signalisation de TOR. L’objectif principal de ma thèse a été d’élucider la fonction de la protéine eIF3h dans la réinitiation après un petit ORF ainsi que dans la réinitiation de la traduction, assurée par TAV, après un long ORF. Nous avons exploité les lignées transgéniques eif3h-1 d’Arabidopsis exprimant la protéine eif3h tronquée de son extrémité C-terminale, qui sont déficientes pour la réinitiation mais pas pour l’initiation de la traduction. Nous avons montré que la phosphorylation de eIF3h est essentielle pour stabiliser eIF3 au niveau des ribosomes durant l’élongation, ce qui favorise la ré-acquisition par le ribosome de facteurs nécessaires à la réinitiation de la traduction, et que la délétion de sa région Ct abolit son intégration dans le complexe eIF3. De plus, nous avons montré que eIF3h, la cible de la voie de signalisation de TOR, interagit avec S6K1. Des protoplastes préparés à partir des plantes mutantes eif3h-1 sont incapables de promouvoir la réinitiation après de longs ORF en présence de TAV. La surexpression de eIF3h, indifféremment de son état de phosphorylation, est indispensable pour restaurer la reinitiation assurée par TAV dans les protoplastes eif3h-1. Par ailleurs, les plantes eif3h-1 déficientes dans la réinitiation, sont résistantes à l’infection par le CaMV démontrant l’importance de eIF3h pour la réplication du CaMV. En revanche, ces plantes eif3h-1 peuvent être infectées par d’autres virus dont la traduction de l’ARN génomique est coiffe- ou IRES-dépendante. Ainsi, nos résultats suggèrent que eIF3h est un facteur de reinitiation important aussi bien pour la reinitiation après un petit qu’après un long ORF (controlée par TAV), et que TAV exploite cette machinerie cellulaire, et plus particulièrement TOR et eIF3h, pour exprimer ses propres protéines par réinitiation de la traductionTranslation of mRNAs that harbor upstream open reading frames (uORFs) within their leader regions operates via a reinitiation mechanism. In plants, reinitiation is up regulated by the target of rapamycin (TOR) signaling via phosphorylation of the subunit h of initiation factor 3 (eIF3). The eif3h-1 mutant expressing the C-terminally truncated eIF3h while maintaining high translation initiation efficiency is not active in reinitiation. Cauliflower mosaic virus (CaMV) pregenomic polycistronic RNA is translated via an exceptional mechanism of reinitiation after long ORF translation under control of CaMV protein TAV, which ensures activation of TOR. To find the link between underlying mechanisms, we examined eIF3h function in cellular and viral context. Here we show that eIF3h, if phosphorylated, has a role in recruitment of eIF3 into actively translating ribosomes that is a prerequisite for formation of reinitiation-competent ribosomal complexes. C-terminal truncation of eIF3h abolished its integration into the eIF3 complex and eIF3 loading on polysomes as manifested by the eIF3 core subunit c. We also show that eIF3h as a putative target of TOR/S6K1 binds S6K1 in vitro. eIF3h phosphorylation is not required for eIF3 complex formation. We demonstrated that eIF3h is essential for TAV to activate reinitiation after long ORF translation. Protoplasts derived from eif3h-1 mutant failed to support TAV function in reinitiation, which is restored only upon overexpression of recombinant eIF3h indifferent to its phosphorylation status. eif3h-1 mutant defective in reinitiation was found resistant to CaMV infection suggesting that eIF3h is critical for virus amplification. In contrast, viruses that evolve translation initiation dependent on either cap or the internal ribosome entry site infect reinitiation deficient mutant. Thus, we conclude that TAV exploits the basic cell reinitiation machinery, particularly TOR and eIF3h, to overcome cellular barriers to reinitiation after long ORF translation

Full textAbstract:
Extensive work is reported in literature on the reduction of iron oxides with carbonaceous reductants. Most of this work considered isothermal reaction of the material mixture, although as shown in some studies, isothermal reaction conditions are not often the norm because of sample size and heating arrangement in the experiment. In industrial processes, such as the rotary hearth type processes and the IFCON® process for iron ore reduction, the norm is non-isothermal reaction. Simulation of industrial processes should take non-isothermal reaction into account if the heat transfer effects within the process are to be investigated. To avoid the complications of coal volatiles in the experimental set-up, few studies were done with coal as reductant. The primary aim of the work presented here is to quantify radiation heat transfer to the surface of an iron ore and coal mixture heated uni-directionally from the sample surface to show the importance of heat transfer in the IFCON® process. Secondary aim of this work are to show the effects of layer thickness, coal volatiles, phase chemistry and particle size in this reaction system. The experimental set-up consists of a tube furnace modified to transport the sample into and out of the experimental tube furnace heating zone under a protected atmosphere, whilst the product gas is analysed throughout the experiment by quadropole mass spectrometer. The sample surface temperature, heating zone temperatures and material bed temperatures were measured throughout the experiment. A sample cutter-splitter was developed to divide the reacted sample into three horizontal segments for chemical analyses. The sample surface temperature and the heating zone temperatures were used as inputs to a radiation network calculation to quantify radiation heat transferred to the sample surface. The radiation network calculation was calibrated against heat-mass balance calculations for pre-reduced ore and graphite samples reacted at furnace temperatures of 1300, 1400 and 1500°C. The results show that radiative and conduction heat transfer control prevails for 16 mm to 40 mm material layers heated uni-directionally from the material layer surface. It is shown that coal volatiles contribute to reduction in the stagnant material layer. Also, smaller particle sizes result in increased reaction rates because of a decrease in the diffusion limited effects which were seen in reaction of the base size of coal and ore particles.Thesis (PhD (Metallurgical Engineering))--University of Pretoria, 2009.
