Full text[Resorting to Group Technology (GT) which is based on the exploitation of product similarities is always topical. Using this technique, we treat two essential problems that belong to the sequence classification. The first meeted is the analyse of assembly logic sequences of product. It is a question to select an alternative sequences verifying criteria in order to reach economic or technique objectives fixed by the firm. The second problem is the classification into families of manufacturing sequences that have similar manufacturing process for FMS (Flexible Manufacturing System) design. So, we propose an original method to solve the first problem. This method, based on hypergraphs generated by tree structure , permit : - the representation of binary sequences by describing the product assembling steps, highlight the parallel character and / or sequential logic of the assembly process , - the analyse of all sequences by calculation of distance between all admissible sequences. This method is used in dynamic control of assembling sequences. To solve the second problem, we propose a new approach based on language theory for sequences classification with keeping the prior approaches based on hierarchic classification : - we treat fundamental case of linear sequences. We propose distance between sequences that verify criteria described in the prior works. - after, we treat the case of arborescent sequences. We propose an algorithm for distance calculation between trees generally and binary trees in particular. This work permit to generalize the works that treat only linear sequences and permit to exploit the task parallelism in assembly sequence. - we solve too the data representation problem when an operation is repeating himself any times into a sequence. ]

Full textAmong the 24 species of Pantoea described so far, five have been reported up to 46 times in 21 countries as phytopathogens of at least 31 crops. Indeed, P. ananatis and P. agglomerans have been reported as phytopathogenic bacteria for at least ten economically important crops, including rice. Recently, Africa Rice Center and its partners have suspected the presence of an emerging bacterium that causes rice bacterial blight in several African countries, and the causal agent has been confirmed as belonging to the genus Pantoea. The objectives of our thesis project were (i) to improve the collection of existing AfricaRice isolates by new collections (ii) to develop diagnostic and characterization tools for fine analysis of genetic, phenotypic and epidemio-follow-up studies. Our results showed that bacteria capable of producing bacterial blight symptoms of rice in Africa form a species complex composed mainly of P. ananatis, P. stewartii and P. agglomerans. Different types of diagnostic tools and characterizations were then developed and validated. The results from the use of these tools helped to point out the presence of this bacterial complex in several African countries and to provide details on its geographical structure. Thus, in total, we diagnosed a bacterial species complex, phytopathogenic of rice in 11 African countries (Benin, Burkina Faso, Burundi, Ghana, Ivory Coast, Mali, Niger, Nigeria, Senegal, Tanzania, Togo). In addition, analyzes of three genomes of african P. ananatis and the development, evaluation, and application of Multiple Locus VNTR Analysis (MLVA) tools provided insights into the phylogenetic and phylogenomic relationships that exist between P. ananatis strains isolated from rice and strains from other sources (plants, animals and environment). Indeed, preliminary results showed that several strains of P. ananatis isolated from rice in Africa, Asia and Europe were phylogenetically linked and formed a group that differentiated them from P. ananatis from other sources. In conclusion, the results of this thesis project provide a solid foundation that will facilitate future studies of Pantoea spp in Africa

Full textThis thesis looks at the evolution of dairy farming and agrarian systems in New Zealand. It explains and characterizes the original path followed by dairy production in this country, which relied on low-input grazing systems until the 90s before moving away from it. It aims also at describing mechanisms underlying the emergence of financialised dairy production structures. Finally, we assess the socio-economic implications of both the shift toward higher-input dairy systems and the financialization of dairy production. This research uses the theoretical framework of Comparative agriculture supplemented by the Anglo-Saxon branch of Agrarian studies. It relied on the analysis-diagnosis the agrarian situation of two small rural areas (the Upper Thames Valley and the Selwyn district). Our work shows how fundamental has been the economic context to explain the focus on low-input grazing systems which characterised dairy farming in the New Zealand until the 90s. It argues that the economic liberalization has been a huge incentive for farmers to shift towards higher-input systems during the 90s. The economic analysis show that low-input systems are nevertheless more efficient in terms of added value and farm income generated per hectare. For its part, financialization permitted to accelerate the development of dairy production, but did not lead to more efficient production systems in terms of added value generated. However, it allows investors who do not take parts into the productive process to capture a significant part of this added value. Finally, the question arises whether or not the agricultural development observed in New Zealand since the 90s is relevant in terms of sustainable development

Full textTelemedicine has been practiced in France since the 1980s. In 2009, the HPST law proposes a legal definition: Telemedicine is “a form of medical practice remotely using ICT”. From this date, the practice has been institutionalized, a national development strategy has been implemented and a sectoral public policy is applied. The objective is to remove regulatory and organizational barriers to the practice of telemedicine. Telemedicine is also becoming a tool for the renewal of public action. However, public policies are unsuccessful. Telemedicine is not developing as the public authorities have desired. The general hypothesis of our research is that instead of removing barriers to the development of telemedicine, public policies dedicated to its practice are actually impeding it. That is why we analyze power relations among stakeholders of regulation. To do this we adopt an institutionalist approach. We question the relevance of the governance model used for for deployment of telemedicine. We highlight that the solutions provided by the institutions in charge of the development of telemedicine can be improductive

Full textProduction is incontestably a very complex activity, in particular for the production of buildings. The control of productivity in construction industry is a real problem since companies are confronted with a great challenge : for a given selling price, the company engages, in front of the owner, to complete the project. The margin obtained at the end of project is not easily foreseeable. We propose to insert a new powerfull approach based on a computer-integrated and logistic on the building sites and their organization for ensuring a better control of production. Then, we develop a whole methodology based on a new cost and productivity indicators model (CIPM) allowing to access the project cost and to measure the productivity according to various evaluation modes. Finely, we propose a new generation of decision support tools facilitating the comparison and follow-up tasks. The prototype OSEP was developed for the organization, follow-up and assessment of the production on building sites. It is validated on a real construction operation of sixty flats in Chambéry (France)

Full textThe aim of this thesis was to isolate new glycoside hydrolases from a Bacillus strain isolated from a Biotope in the south of Tunisia. This strain was able to produce a lichenase and an amylase at 45 ° C and pH 9. The production of these two hydrolases was optimized in solid state fermentaion using millet, a low cost. agro-resource as solid substrate. This optimization was carried out using response surface methodology (RSM) based on Doehlert design. We obtained production levels of around 540 units of amylase activity per gram of solid substrate and 503 U / g of lichenase activity.Both proteins were subsequently purified and characterized biochemically. The amylase has a pH and a temperature optimum of activity of 5 and 70 ° C, respectively. The lichenase showed a remarkable thermostability which distinguish it from described lichenases. Indeed, the enzyme retained more than 20% of its activity at 100 ° C, and more than 60% of its activity after incubation for 30 min at 90 ° C. The gene encoding this protein was isolated by the construction of genomic a library in E. coli. Comparison of its sequence with the NCBI database showed that the gene coding for UEB-S lichenase has a very high homology with that of Bacillus subtilis 168, with a difference in the position of only two amino acids A model for UEB-S lichenase built during this study suggests that one of these two amino acids (Val 69) could be involved in its thermostability probabely by changing the geometry of the calcium binding site
El, Maiss Janwa. "Conception des matériaux à faible énergie de surface : une nouvelle étape pour la production durable." Thesis, Nice, 2015. http://www.theses.fr/2015NICE4073.
Full textTwo types of Low surface energy materials LSEMs can be recognized; those which are firstly applied on solid surfaces to elaborate superhydro/oleophobic surfaces that are micro and nano structured, and secondly at the water/air interface to synthesize new ecofriendly surfactants. LSEMs are essentially made from fluorinated compounds due to their unique properties of being both hydro and oleophobic as well as, their thermal and chemical stability in corrosive media. This project shows that the creation of superhydrophobic materials with high oleophobic properties does not necessarily require the utilization of long and bioaccumulative perfluorocarbon chains. Two approaches were adopted in this field. The first strategy was to develop ProDOT derivatives bearing short fluorinated chains to study the influence of the fluorinated chain length on the surface wettability. The proceeding part was to explore the effect of the introduction of a hydrocarbon tail and study the effect of their type and chain length on the surface properties. Another important aspect of this research involves the application of LSEMs on soft materials like surfactants as alternatives to toxic perfluorinated homologues. This study was done to explore the effect of the variant hydrocarbon chains with a short fluorinated tail of hybrid surfactants as well as the effect of the polar head. In this area, two families of hybrid sulfate and bisulfates were synthesized. Their physico-chemical properties were investigated and interesting results were obtained

Full textThis work is focused on the design and fabrication of a new print head for biological sample deposition to elaborate DNA biochips. Biochips allow to analyse and to detect thousands of DNA samples (or proteins) in few hours. Biochips fabrication consists in arranging biological samples in form of spots on a solid substrate forming a microarray. Among current fabrications techniques, pin microarrayer is a simple and versatile recognized process. This process is based on direct contact between thin pins and the biochip support. The deposition is made through capillary forces. We propose two mechanical solutions for the improvement of the production performances in term of production time, flexibility and precision, in correspondence with the evolution of biological analysis methods. The first consists in compliant mechanism design for pin guiding. It makes it possible to offer an accurate positioning of each print pin and increases touching force control during spot deposition operation. Low space is available for each flexible guiding and we propose a new flexible structure. The second solution is selecting pins at each printing operation by up-and-down movement of pins. Proposed print head has 1536 pins. Operations of printing are decreased and vertical displacements of pins are reduced productivity is significantly increased. Reliability and flexibility are significantly improved. Shape memory alloy microactuators are developed for pin selection

Full textLa reconfiguration de l’énonciation dégage les ressorts d’une écriture nouvelle marquée par une narration éclatée, une spatialité multiple et une innovation thématique. La transgression narrative s’intègre au rang des discours de la déconstruction caractéristique de la postmodernité et se donne à lire comme le reflet de l’être de l’entre-deux qu’est l’écrivain migrant comme d’ailleurs son protagoniste. L’espace dans lequel évolue ce dernier peut être interprété comme une transteritorialité dans laquelle se moule la création littéraire marquée du sceau de l’altérité et traduit la « transidentité » du personnage évoluant dans cet espace. La perspective thématique renforce cette idée de l’altérité mondiale structurant le récit africain contemporain. Elle s’engage dans la voie des mutations et des transgressions caractéristiques de la mise en relation de l’africanité et de la mondialisation comme lieu de l’écriture/lecture du roman contemporain.
Le mode d’écriture nous offre un cadre linguistique et stylistique dans lequel se joue l’altérité africanité-mondialisation. Le romancier de la nouvelle génération retravaille la langue française à l’aide des ingrédients des langues et des cultures dans lesquelles il baigne. Cette manipulation linguistico-stylistique est rendue possible par le jeu interlinguistique et le registre humoristico-ironique qui produisent une esthétique du « risible » face aux défis de l’altérité. L’écrivain africain contemporain, décomplexé par ces manipulations linguistique et stylistique, exploite les ressources de l’oralité en vue de concilier la pluralité des formes d’expression et des pratiques langagières de son environnement. Cette stratégie d’écriture produit une esthétique de l’oraliture, celle-là même qui, tout en exaltant les vertus de l’écriture, recourt aux différents procédés offerts par l’oralité, versant de l’africanité du texte contemporain, pour marquer une opposition contre l’écriture et l’Occident qui l’incarne./The African novel by the new generation is made at the meeting point of languages and cultures. In its theoretical and paratextual orientation, the fiction discourse by the new generation can be summed up as a « universality-oriented modernity », a place of dialectic link between africanity and globalization. The ideological context of creation of this literature and the identity questioning bring us to consider africanity as a dynamic notion and the literary globalization as a way to competition and literary legitimacy.
The peritextual discourse, which is a high place of readability/visibility, initiates the strategies of this otherness which the novelist develops largely in textual enunciation.
Reshaping the enunciation shows the motivation of a new writing characterized by a breaking up narration, a multiple area coverage and a thematic innovation. Narrative transgression is integrated in the rank of discourses of deconstruction characterizing postmodernity. It is to be read as a reflection of the being in the space between, this is the migrant writer as well as his protagonist. The space in which the latter evolves can be interpreted as a transterritoriarity in which is moulded literary creation sealed by otherness and shows « transidentity » of the character evolving in that space. The thematic perspective reinforces this idea of global otherness structuring the African contemporary narration. It moves into mutations and transgressions characterizing the relationship between africanity and globalization as a place of writing/reading of contemporary novel.
The writing mode gives us a linguistic and stylistic framework in which takes place the otherness africanity-globalization. The new generation novelist works on the French language he uses by means of ingredients of languages and cultures surrounding him. This linguistic and stylistic manipulation is made possible by an interlinguistic game and the humoristic and ironic register which produce aesthetics of the “funny” in front of otherness challenges. The contemporary African writer, encouraged by these linguistic and stylistic manipulations, exploits the oral ressources in order to reconcile the plurality of forms of expression and of language practices of his environment. This writing strategy produces aesthetics of orality, the one which, in addition to exalting the virtues of writing, has recourse to different procedures of orality, showing thus africanity of contemporary text, to mark an opposition against writing and the Western world which embodies it.

Full textThe preparation of new tungsten based catalyst using Surface Organometallic Chemistry is described in this thesis. These catalysts have been prepared for the production of propylene from ethylene and/or butenes. Two types of catalyst have been developed. Supported tungsten hydrides, resulting from the surface reaction of [W(CtBu)(CH2 tBu)3] with -alumina followed by a treatment under H2 at 150°C have been prepared. The characterizations by several spectroscopic techniques (IR, SSNMR, Raman and EXAFS) and stoichiometric reactivity combined by with theoretical calculations (DFT) have demonstrated the presence of two tungsten hydride surface species: a neutral and a cationic. This catalyst have shown outstanding reactivity for the direct conversion of ethylene to propylene 150°C following a tri-functional mechanism (dimerization, isomerization and crossmetathesis). The deactivation pathway has been attributes to ethylene oligomerization mainly due to the presence of cationic surface species. To circumvent this deactivation, other reactions affording propylene have been developed (butenes conversion, ethylene/2-butene and isobutene/2-butene cross metathesis). The conversion of 2-butene to propylene, until then unreported, has been notably studied. Finally, a second type of catalyst, models of the active site of supported tungsten hydrides and of WO3/SiO2 catalyst, has been prepared and characterized. These new catalysts, bearing an oxide ligand, have been shown to be more active than their imido counterparts. These later deactivates quikely by metallacyclobutane decomposition leading to the reduction of the tungsten non observed in the case of oxo systems

Full textPrevious works on marine bacteria led to the discovery of molecules of great biotechnological interest. Under unusual physical and chemical conditions some microorganisms have developed various survival strategies including exopolysaccharides (EPS) and Poly-3-hydroxyalkanoates (PHAs) production. Due to their many interesting biological, physical and chemical properties, those polymers have found applications in many industrial sectors. Due to interesting physical and chemical properties, EPS can find applications in many industrial sectors including the food industry, cosmetics, for oil and metal recovery from industrial waste and in the mining industry as well. During the last decades EPS have also been demonstrated as interesting bioactive molecules with many applications for human health. PHAs are biopolyesters accumulated as granules in bacteria in order to endure long starving periods. Those biodegradable biopolymers can be used as an alternative to petroleum derived polymers and can be produced from renewable carbon sources. PHAs exhibit a wide variety of properties and structures depending of the carbon source available and the microorganism used for the production. New Caledonia (NC) is frequently referred as a hotspot biodiversity. During a prospection campaign performed in different marine costal ecosystems of NC, a great number (770) of bacteria were isolated from different locations. Screening showed that 55% of the isolates were able to produce under lab conditions EPS and 53% to produce PHA. Partial chemical characterization was performed on purified samples using colorimetric methods, infrared spectrometry (FTIR), gas chromatography (GC) and nuclear magnetic resonance (NMR). Marine bacteria from New Caledonian ecosystems were shown to produce EPS with unusual chemical composition with potential applications in cosmetics. Preliminary experiments also showed high metal-binding capacity with applications in bioremediation. Different PHAs were also produced using different types of sugars and oil as renewable resources. Blue biotechnologies can have various applications in many industrial sectors (Health, food industry, environment, cosmetics etc…) and there is a great international demand for new molecules issue from marine areas. New Caledonian marine bacteria have proved their capacity for producing innovative biopolymers with a wide range of application that can be valuating in on short time period (environment, cosmetics) or at long time (pharmaceutics, surgeries). These applications are promising in order to develop
Keoshkerian, Houry. "Mesure de la production de di-bosons WZ auprès du LHC avec l'expérience ATLAS." Thesis, Grenoble, 2014. http://www.theses.fr/2014GRENY030/document.
Full textThis thesis is performed in the frame of the ATLAS experiment at the LHC.A first part of the work presented in this document consists on the time calibration of the ATLAS Liquid Argon (LAr) calorimeter. The control of the time alignment of the calorimeter is important for the goodness of the quality of the energy reconstructed in the calorimeter. The results presented in this thesis have allowed an improvement of 30% of the global time resolution of the LAr calorimeter.The Standard model of particle physics predicts, during proton collisions, the production of the W and Z weak bosons as a pair due to the interaction of a quark with an anti-quark. The diboson production can be sensitive to the couplings between vector bosons.An anomalous deviation of these couplings from the prediction of the SM would point to the presence of new physics.The use of the full statistics of the 2012 ATLAS data allowed us to increase the precision of the measurement of these couplings compared to previous results based on smaller datasets.This thesis presents therefore the measurement of the WZ dibosons production cross section using the full 2012 data collected by the ATLAS experiment from the p-p collisions at the LHC at a center-of-mass energy of 8~TeV. Also, with the available statistics the ratio of the production cross sections of W^+Z and W^-Z events were measured. This measurement was not performed previously using the 2011 data due to a lack of statistics. Finally, measurements of the normalized differential cross section as a function of four kinematic variables were also performed.The precision on the measured integrated cross section is 5.5% which is reached mainly by the reduction of the statistical uncertainty by 55% with respect to the previous ATLAS results. Therefore, the order of magnitude of the experimental uncertainties on the measurement started to approach that of the theoretical predictions. This is promising for future measurements at the LHC as with higher statistics the experimental precision is expected to overcome the theoretical one

Full textThis thesis examines and shows ways in which the structure of networks can provide a new matrix for the production of artworks. In order to answer this question we start by studying: the evolution of the term ‘network’ from the ancient times up to nowadays; the theories that refer to network structure or network dynamics. Then we present the applications of these theories into both art and science. We list and analyze eight different types of networks and then we feature artworks which have been inspired by these network types or have used the network structure of a certain type as a matrix for art making. We propose the Imaginary Lines project, a three-dimensional network model which is based on the concept of a metro composed of imaginary lines. More precisely Imaginary Lines metro network encompasses seven paradoxical lines which move, (dis)appear and produce supplementary infrastructure. The Imaginary Lines metro unveils the importance of geography and spatiality, in contrast with topological network graphic representations, which remain insufficient, in terms of utmost accuracy in representation and comprehension of network structure. Additionally, the Imaginary Lines network innovation lays in its infrastructure dynamics as well as in its self-organisation. The objective of the Imaginary Lines artistic project is to visualise a concept by creating an unusual metro, which goes beyond traditional fixed-route transport networks and can support alternative forms of urban transport development

Full textThis thesis aims to document the context in which metallurgy occured during the transition period and the colonisation of New France and, through the application of theoretical concepts, principally that of the chaînes opératoires of Leroi-Ghouran developed in his study, L’homme et la Matière, conducted in 1943, to provide a better understanding of an important period in the colonial history of North America. Topics specifi c to the processing of metals, the craftsmanship of objects and the infl uence of technology have only been briefly described in studies of material culture in North America. Knowledge concerning metalworkers as well as the social and economic impact of their craft during the 17th and 18th centuries is limited. This research focuses on the study of the chaînes opératoires and the metallurgical techniques employed by Native American and European artisans, as well as the technological choices made throughout the process of metal production during a period of technological adaptation to the environment of New France. The artefacts are studied using tomography (CT scan) and by principles of materials engineering with the goals of identifying the source of the metal, the technical sig nature of the artisans, and the technological problems related to a lack of raw material, as well as to climate and fuel.

Full textIn the last 40 years, climate change has been increasingly taken intoaccount. Various observers have started to tell a story: the story of small Pacific atollisland states that might disappear beneath the rising seas. The argument developedin this thesis is that this story is a "public action narative" which aims at drawingattention towards those states and at inciting policy makers to prevent the risk or tofind a solution. Those "sinking island States narratives" display two particularcharacteristics: they are not linked to an existing policy and they are used by variousactors from the political sphere and the civil society.Building on the policy narratives literature, this thesis aims at analysing theproduction, the dissemination and the framing of the sinking island states narratives.It is based on mixed methods and combines a qualitative framework and a statisticalanalysis of textual data

Full textThis thesis focuses on the role of French film producers as central figures in the production process of each film. Notwithstanding their important contribution, film producers are largely forgotten in the history of the seventh art and little known to the general public, the studies having focused more on actresses, screenwriters and directors. It is precisely this lack that the present research proposes to fill by exploring the careers, the motivations, the difficulties encountered and the daily life of the French film producers, by highlighting what they brought, by showing how they made to evolve the profession of producer and in particular how much they influenced the economy of the cinema and shaped, by their work, our imagination. Our analysis is articulated in three stages, in order to understand the process that has favored the advent of women in French film production since the Nouvelle Vague until today. The project to enhance the role of producers not only reveals a part of the history of the seventh art, but also to ask the question of film production declined to the feminine at the heart of the reflection on the work. Our thesis aims to reveal, through the words, actions and management of producers, the history of the seventh art through a new perspective, to better understand the cultural reality and its contradictions. It is certain that there can be no question of the history of cinema without these women

Full textThis thesis shows how local social and educational policy, deployed at the crossroad of several public sectors (educative, social, health, leisure, ...) and representative of the current trends in social intervention paths (individualisation, activation, contracting, ...) is appropriate, constructed and transformed by actors on the field, as well as in the interaction with users. From the study of the Educational Success operation in Toulouse from 2006 to 2009, this research highlights the different phases that have marked the integration and structuring of this new local social public action. From a critical reception by the local socio-educative professionals to a progressive acceptance and mobilization, our investigations show how local actors contributed to transforming the operation into a "palliative" and presentist policy in answer to the deficiencies and malfunctions of the local Socio-educative system. We then observe a "relative" adherence to this new public policy, in the sense that the reluctances expressed by the actors at the outset do not disappear, but are set aside considering the existing needs and the situations priorities. The actors are not fooled by the attempts to change the system and continue to resist them seeking to manipulate the operation. However, even if the adherence is limited, it could end by gradually opening the path to change under the influence of the a series of operation creation, including the Educational Success operation, which tend to promote a new social paradigm

Full textMuseum mediation as a prefigurative system is studied here through a semio-pragmatic approach. Particular attention is given to the processes of meaning production as well as to communicational contexts. Starting from the expographic study of the Musée International de la Parfumerie as a mediating situation, this research considers museum mediation from two different angles : epistemological ( as a cultural practice and as a concept per se) and pragmatic through the notion of mediation system. Within the museum space, the notion of a mediation system synergizes the two conceptions of the exhibit, ie the exhibit as text (responding to a constitutive and communication intentionality) and the exhibit as a discursive construction (which sets up a triple discursive dimension : prefigurative, configurative and refigurative). The analysis of mediation systems thus permits questioning the status of museum objects (material as well as immaterial), the role of space and the place of the public in the process of meaning production as a form of mediation

Full textHousing production in France is at the heart of several academic debates concerning State intervention, private production models and local governance. In each of them, some authors have expressed the idea that western countries have been affected by a neoliberalization process since the 1970s. But our study of the fiscal aid to rental investment, which is one of the tools of national housing policy, shows the limits of this interpretation, especially in the 2000s. Based on a methodology combining qualitative and quantitative analysis, our research however shows that a new political economy of housing production is emerging. Along with decentralization, there are now two public authorities involved in regulating the market: the State by law and the local governments by negotiation with private parties. And this duality creates contradictions between national issues (especially macroeconomic) and local priorities. In this context, the property development sector has witnessed major changes: if State incentives have induced the emergence of new participants and of a specific model of production, the new public regulation implies a change in strategies. Urban production is concerned by these changes. Not only because State regulation has an impact on supply but also because the unequal ability of local governments to negotiate with developers make small and medium-sized cities more exposed to a gap between real housing production and public expectations

Full textSince the end of the eighties, plantation economy based on coffee and cocoa is facing in Côte d’Ivoire a deep crisis. The imminent disappearance of last forest masses and the reduction of access to labour force witch is linked to it, are indeed threatening reproduction within the system. What possible solutions are there today? Are we seeing the beginning of intensification work or technology or are we seeing a slow disappearance of the system through emigration and labour forces? How does one explain the current changes? To follow and fully understand the evolution of this agricultural system of production, our research work is based on the following hypothesis: migrants are more concerned with the survival of their domestic group and the social link with their community of origin than with safeguarding their space of production. Migration, in the sense that it constitutes the instrument of this desire of social reproduction, naturally serves as the "revealing" factor and basis for "analysis" of the economic system based on coffee and cocoa. Through this migration factor, we aim at demonstrating how the logic of family and community reproduction command the structuring and de-structuring of the plantation economy

Full textOriginally identified as dietary lipid detergents, bile acids (BA) are now recognized as signaling molecules which bind to the transmembrane receptor TGR5 and the nuclear receptor FXR (Farnesoid X Receptor). Upon binding to TGR5 at the surface of enteroendocrine L cells, bile acids (BA) promote the secretion of the incretin GLP-1 which potentiates the glucose-induced insulin secretion by pancreatic beta-cells. More than 50% of the insulin secretion in response to glucose is mediated by GLP-1 and the other incretin Glucose-dependent Insulinotropic Polypeptide (GIP). Once secreted, GLP-1 is rapidly (2-3 minutes) degraded by the endothelial enzyme Dipeptydil Peptidase 4 (DPP4). GLP-1 analogues and DPP4 inhibitors are successfully used for the treatment of T2D. FXR is a ligand-activated nuclear receptor highly expressed in the liver and in the distal intestine. FXR controls BA, lipid and glucose metabolism. Whether FXR is expressed, functional in intestinal enteroendocrine L cells and in which extend its activation affects GLP-1 production are not yet reported. Encouraging data were obtained during my M2 training course. The aim of my thesis was thus to assess whether FXR in enteroendocrines cells could participate in the control of the deregulation of glucose homeostasis. Multiple in vitro, ex vivo and in vivo human and murine models allowed us to show that FXR is present and functional in L cells. FXR activation decreases GLP-1 production and secretion in L cells by inhibiting glycolysis pathway through an interference with the carbohydrate responsive transcription factor ChREBP. Finally, I identified an additional mechanism of action of the bile acid sequestrant Colesevelam, a molecule currently successfully used in USA for treating type 2 diabetic patients

Full textHypertriglyceridemia (HTG) correspond to an increase of triglyceride-rich lipoproteins (TGRL) circulating concentration, as a consequence of an increase in the synthesis of or a decrease in their catabolism, most classically described. In nearly 50% of patients with severe hypertriglyceridemia (HTG), no genetic cause is identified, either in familial chylomicronemia syndrome (FCS) or in multifactorial chylomicronemia syndrome (MCS). To gain new insights and to improve patient’s characterization, it remains important to conduct accurate phenotype-genotype association studies through close collaboration with referent lipidologists, and to develop high-performance tools for molecular diagnosis. Firstly, the assessment of pre-heparin LPL concentration as well as LPL activity 60 minutes after heparin injection, enabled the identification of two subgroups within 62 genotyped MCS patients Secondly, the development of a new sequencing generation workflow exploring simultaneously the 9 most prevalent genes in dyslipidemia, allowed the detection of single nucleotide variations with sensitivity equivalent to Sanger sequencing, but also allowed the detection of copy number variations. Collective consideration of the results underlines the complexity of the regulation mechanisms of TGRL metabolism and the interest of gene-gene interactions study. Thus, the studies presented herein bring new hypothesis to explore for understanding the pathophysiological mechanisms of severe HTG and to improve molecular diagnosis tools available for phenotype-genotype association studies

Full textSustainable chemical production is one of the endeavour of the post-oil era. Amongst the possible techniques, metabolic engineering which aims at producing novel compounds through genetic engineering of micro-organism is seen as one of the most promising techniques. One of the problem met by metabolic engineers is often the absence of diffusion or pumping mechanism expelling the compound of interest produced in the cell cytoplasm towards the outer environment, which reduces the process efficiency because of kinetic and toxicity concerns.During this PhD, we explored the possibility of producing impermeable compounds on the surface of a cell by anchoring the last reaction enzyme using « Yeast surface display » techniques.As PhD disputation we first looked at the industrial interest of metabolic engineering in the whole bioeconomy framework. We then looked at the membrane permeability issues met for the production of some compounds. We evaluated the different membrane permeability techniques and explored the possibility realizing a predictive technique using quantitative structure-property relationship (QSAR). We evaluated the different yeast-display systems available and paved the way for the discovery of new systems more suitable for metabolic engineenering. We developped a dedicated program tool for large PCR fragment library design. Finally we built several toy metabolic pathways in yeast in order to evaluate the interest of the technique
