Perrin, Adrien. "Biocicatrisation des structures en béton par injection et aspersion de milieux rhéofluidifiants inoculés". Electronic Thesis or Diss., Ecole nationale supérieure Mines-Télécom Lille Douai, 2022. http://www.theses.fr/2022MTLD0003.
Concrete, the most widely used construction material, can deteriorate on contact with its environment, leading to cracks which may negatively impact its durability. The most commonly used method for repairing fine cracks is the injection of resins (epoxy, polyurethane, etc.). However, these potentially polluting materials can have a limited lifespan and are sometimes incompatible with concrete. The objective of this thesis is to develop a biological crack repair method for concrete structures. Crack sealing is achieved by injecting an inoculated thickened liquid, leading to the production of bio-based calcium carbonate and biofilm into the crack. The development has two main innovations : a specific microbial inoculum and a predictive model for the design and the production of shear thinning injection liquid specifically optimized for the opening of the crack to be repair.The microbial inoculum is a consortium of native microorganisms adapted to cementitious materials. The consortium grows rapidly and produces significant amount of calcite and vaterite from the metabolization of calcium lactate under typical environmental conditions found in a crack (humidity, 20°C and alkaline pH). The predictive model has demonstred its effectiveness in designing injectable and biocompatible formulations in cracks with opening ranging from 40 to 1000 µm. A selected formulation inoculated with the microbial consortium was injected into mortar samples with a range of cracks opening, and then stored under laboratory conditions (20°C, 100% relative humidity). For fine cracks (approximately 100 µn) injection of the inoculated thickened formulation reduced the apparent crack opening by 84-90%. For larger cracks (250 and 450 µm), the apparent crack opening was reduced by 77%. The same biocicatrisation system was used to bio-repair two 400 µm cracks in a concret slab (1 x 2 x 0,5) stored in laboratory conditions (20°C). Biotreatment of the cracks resulted in a 99% reduction in water permeability for both cracks, with the confirmation that some scaling materials formed in the cracks are the result of a biological process. Two injection methods suitable for dry and wet cracks have been developed for bio-treatement tests performed on larger scale concrete structures : for dry cracks, the EDF VeRCoRs mock-up, which is 1/3 scale nuclear reactor enclosure ; anf for wet cracks, a dam in the hydroelectric power plant of Weedon, Canada. These two on-site trials have produced promising results and are a significant contribution to the proof of concept of this new approach for biotreament of cracks

Chenut, Charles-Henry. "Le contrat de consortium". Paris 10, 2001. http://www.theses.fr/2001PA100110.
The consortium contract is a particular partnership. Although there is no legal definition in French law, a consortium - which is a kind of contractual joint-venture - may be described as an agreement of cooperation between independent parties (generally of similar economic weight) who venture into a common objective and who negociate as equals. Contractual joint ventures generally do not include the main activities of the members of the consortium but are used either for specific operations or for ancillary activities where the joint venturers need assistance. Consortium contracts should be selected when a common entity structure is not justified because the common activities are to be carried out on a short term or experimental basis, do not require significant financing or for confidentiality reasons. A consortium is created by a direct contractual relationship between joint venturers through one or several contrats without formation of a entity such as a partnership or corporation. It is in fact a simple contrat of cooperation between two or several partners pursuing the same objectives. However, in addition to a statement on their objectives and the mean to be taken to achieve them, the parties must be define 'who does what' in a very precise manner as by definition there is no common entity through which the parties' joint endeavours will be channelled. This consitutes a fundamental différence with the other types of joint ventures which give rise to legal entities having a independent legal statuts. In spite of the absence of a separate legal entity, the members of the consortium have certain obligations, which, if not complied with pursuant of the joint venture contrats, will entail general penalties under the applicable contractual law and possibly specific penalties which may be stipulated in such contrats, enforceable through court proceedings or, more often, arbitration proceedings. Under french law, consortium contract is known as undesignated contrat as it is not specifically categorised in French civil code. Contractual joint ventures are diverse and numerous. However, an analysis of joint venture contracts reveals that they have common points, whaterver the object of the consortium may be. Then, a specific status of this particular cooperation appears. It is the aim of our work to demonstrate its existence

Effects of caffeine on microbial consortia were studied using denaturing gradient gel electrophoresis (DGGE), providing a community-scale view of changes in microbial consortia upon caffeine addition. Surprisingly, caffeine removal was achieved indigenously by the microbial consortium. Principal component analysis was used to analyze differences in DGGE banding patterns between control and caffeine-exposed mixed cultures.

A gasoline-degrading consortium was readapted in liquid using gasoline/methyl tert-butyl ether and was tested for its hexane-degradation kinetics in liquid microcosm and in a bench-scale biofilter. On the 28 last days, Elimination Capacity and CO2 production rate in the biofilter remained constant. A sample was collected to characterize the biodiversity and compare it with that of the initial gasoline consortium and the same consortium adapted on hexane in liquid microcosm. Significant differences between the populations were observed, indicating a probable adaptation to the culture conditions. Three strains including two Actinomycetes were isolated from the consortium. One of them, SP2B, degrade hexane and other short-alkane compared with the type strain phylogenetically related (Rhodococcus ruber DSM 43338T). Cellular fatty-acid profiles on various alkanes, as well as the growth in the presence of hexane-metabolism intermediaries identical for both strains didn't allow to understand the phenotypic differences. Moreover, an identical gene, alkB, was found in both strains. It codes for an alkane monooxygenase, which product is probably involved in long-chain-alkane degradation. Another alkB gene, identified in SP2B, could therefore be involved in the degradation specificity of the strain. Studies are in progress in order to precisely characterize this new gene and to understand the regulations on the expression of all the elements involved in hexane degradation

Distillery effluent from sugarcane molasses leads to an environmental pollution due to its large volume and the presence of dark brown colored compounds, known as melanoidins. In this study, a bacterial consortium CONS8 isolated from waterfall sediments in Maehongsorn province was selected as a molasses-decolorizing consortium. Consortium CONS8 was able to decolorize, only within 2 days, in Erlenmeyer flasks, three different synthetic wastewaters containing either Viandox sauce (13.5% v/v), beet molasses wastewater (41.5% v/v) or sugarcane molasses wastewater (20% v/v) at 9.5, 8.0 and 17.5%, respectively. Four predominant bacteria present in the consortium CONS8 were identified by the 16S rDNA analysis. To achieve the highest decolorization, the artificial bacterial consortium MMP1 comprising Klebsiella oxytoca, Serratia mercescens (T2) and unknown bacterium DQ817737 (T4), was constructed. Under optimized conditions (aeration, pH), the bacterial consortium MMP1 was able to decolorize the synthetic melanoidins-containing wastewater at 18.3% within 2 days. The comparison of decolorization by the consortium MMP1 with abiotic control proved that the color removal for synthetic melanoidins-containing wastewater medium was mainly due to biotic activity of bacterial cells, without any adsorption phenomena. Supplement of nutrients and vitamin B did not promote melanoidins decolorization by bacterial consortium MMP1. Finally, the performance of a membrane bioreactor (MBR) for synthetic melanoidins-containing wastewater treatment was investigated at laboratory scale, with a mineral membrane. The reactor seeding was made with the MMP1 bacterial consortium inoculum. The reactor was performed with several hydraulic retention times (HRT) of 15, 20, and 40 hours. The performances were analyzed in terms of COD, color removal and biomass in the reactor. The results indicated that the higher COD and color removal efficiency were achieved with the longer HRT

Symbiotic agriculture is a new cultivation process that involves the use of microbial inoculants, such as fungi, bacteria and yeasts that make the rhizosphere (the space from 1 to 3 millimeters that envelops the roots of plants), extremely rich in beneficial microorganisms. These microorganisms constitute the microbial biota which, in addition to acting as a support for the well-being of the plants that host them, can contribute to the antagonistic action against potentially pathogenic microorganisms. Several products based on microorganisms are available on the market: they are advertised as biofertilisers, biostimulants, biopesticides, growth enancers, resistance inducers, etc... Therefore, the aim of the research is to set up rules, procedures and protocols to be used during the industrial production of microbials, in order to obtain an efficient, effective and sustainable microbial formulation, whose quality is checked along the production chain. Only by performing quality control checks, microbials can be a valid alternative to chemical pesticides. Research started from a well known, commercial biosimulant, namedMicosat F UNO, consisting of a microbiological consortium. Research was oriented towards the development of a "quality protocol" considering both the individual microorganisms present in the product and the consortium as a whole. The individual components were selected, thoroughly identified, studied and characterized considering their microbe-microbe and plant-microbe interactions. Full genome sequence and biochemical pathways were done and characterised for one particular benficial organism, in order to scietifically support its role as beneficial organisms and as possible, patentable active substance. Additionally, the production process was analyzed and control points were identified in order to obtain a qualitatively valid commercial product.

The intensification of agricultural production systems is increasing in the current agriculture. In this sense, the simultaneous planting forage to grain crops, constitutes an alternative in the intensification of the production system, which can increase or not the productivity of the main crop, and produce straw for mulching. In order to check the occurrence of changes in the physical properties of the soil and in corn yield and dry matter production due to the corn consortium / forage in two sowing dates, this study was conducted in the experimental area of the Department of Agricultural Engineering of the Federal University of CearÃ. The design was used in a randomized block design in a factorial scheme (3x2) + 1 with four replications, totaling 28 experimental units. The treatments consisted of three forages: Brachiaria, Panicum maximum cv. MombaÃa and Crotalaria spectabilis intercropped with maize in two of fodder sowing dates, between the lines of simultaneous sowing maize (season 1 - E1) and corn leading the V4 stage of corn (season 2 - E2), and the control. The results showed that intercropping maize / forage did not interfere in phytotechnical characteristics of corn, nor in productivity, however produced changes in soil physical properties when the day of sowing in season 1. Despite the changes that have occurred in the soil, they were not sufficient to enhance the productivity of maize, which could possibly be related assessments on only one crop cycle. But when the goal was the production of dry straw, it is concluded that fodder Brachiaria brizantha and Mombasa at the time 1 (E1) are recommended
A intensificaÃÃo dos sistemas de produÃÃo agrÃcola à cada vez maior na atual agricultura. Nesse sentido, o plantio simultÃneo de forrageiras com culturas produtoras de grÃos, constitui em uma alternativa na intensificaÃÃo do sistema de produÃÃo, que poderà incrementar ou nÃo a produtividade da cultura principal, alÃm de produzir palha para cobertura do solo. Com o objetivo de verificar a ocorrÃncia de mudanÃas nas propriedades fÃsicas do solo, bem como na produtividade do milho e produÃÃo de matÃria seca em funÃÃo do consÃrcio milho/forrageiras em duas Ãpocas de semeadura, o presente trabalho foi conduzido na Ãrea experimental do Departamento de Engenharia AgrÃcola da Universidade Federal do CearÃ. Foi utilizado o delineamento em blocos ao acaso, no esquema fatorial (3x2) + 1 com quatro repetiÃÃes, totalizando 28 unidades experimentais. Os tratamentos foram constituÃdos por trÃs forrageiras: Brachiaria brizantha, Panicum maximum cv. MombaÃa e CrotalÃria spectabilis consorciadas com o milho em duas Ãpocas de semeadura das forrageiras, na entrelinha do milho simultÃneo a semeadura (Ãpoca 1 â E1) e na entrelinha do milho no estÃdio V4 do milho (Ãpoca 2 â E2), alÃm da testemunha. Os resultados permitiram concluir que a consorciaÃÃo milho/forrageiras nÃo interferiram nas caracterÃsticas fitotÃcnicas do milho, nem tampouco, na produtividade, porÃm proporcionaram modificaÃÃes nas propriedades fÃsicas do solo quando da realizaÃÃo da semeadura na Ãpoca 1. Apesar das modificaÃÃes ocorridas no solo, as mesmas nÃo foram suficientes em incrementar a produtividade do milho, o que possivelmente pode estar relacionado as avaliaÃÃes em apenas um ciclo da cultura. Jà quando o objetivo foi a produÃÃo de matÃria seca de palha, conclui-se que as forrageiras Brachiaria Brizantha e MombaÃa na Ãpoca 1 (E1) sÃo recomendadas

This study analyzes the industry of consortium since banks started retailing it. It tries to understand the most relevant transformations that have taken place since that day. In order to do so, the following aspects of the product consortium are analyzed: its origin and evolution, the way it works, its peculiarities as a way to acquire goods and its attractiveness. The consortium is also compared to other modes of good acquisition. In an attempt to justify the interest of retail banks in managing and assembling consortia, the recent history of the National Financial System of Brazil is reviewed. This review highlights the importance of the income which is a result of services offered in a stabilized price-economy. The changes in behavior and the modifications in the consortium industry caused by the joining of the retail banks in this business are analyzed on the base of the participation of these institutions in this particular industry.

The Role of Research Consortia through the Eyes of Principals No Child Left Behind legislation calls for educational leaders to use evidence to inform practice. Principals are charged with improving student achievement by adjusting resources and policies based on most recent evidence and research available to them. A research consortium is an institution that partners with a school district to engage in ongoing research for the purpose of improving practice.
The purpose of this study was to understand principals' perceptions of research consortia associated with their district and to discover how principals used evidence produced by consortia. The overarching question of the study was "How do principals learn about and utilize evidence produced by research consortia associated with their district."
To address my research question, I interviewed 22 principals in two school districts that work with research consortia. The participants included 10 Baltimore City Public School principals and 12 Chicago Public School principals. The Baltimore Education Research Consortium (BERC) is associated with Baltimore City Public Schools. The University of Chicago Consortium on Chicago School Research (CCSR) is associated with Chicago Public Schools.
Using an interpretivist interview design, four major findings emerged from this study: (1) principals, who are aware of the evidence produced by research consortia, use it to inform practice and decision-making, (2) principals do not have many direct interactions with researchers in the consortia and do not see a pathway to connect with researchers in the consortia, (3) principals who knew about the research consortium in their district have positive perceptions of it, however some principals are skeptical of survey data regardless of the source, and (4) principals in this study explained that consortia do address the evidence to practice gap, but principals did not see an opportunity to contribute to research design.

Xyloglucan (XyG), galactoglucomannan (GgM) and glucuronoarabinoxylan (GAX) are key hemicelluloses regulating plant cell wall functions in dicots. However, the impact of their diverse sugar composition and distribution in planta remains unclear. To detail their fine structure, degradation by commercial enzymes of purified native acetylated XyG, GgM and GAX fractions from apple revealed structural variations between different XyG and GgM populations and demonstrated first evidence for arabinose and/or xylose substitution on GAX. However, more detailed fine structural aspects of these polysaccharides require new enzymatic tools with regard to cleaving site specificities. In this aim, we used a genome mining approach coupled with a medium- through put screening procedure to identify hemicellulose-degrading enzymes from marine and land bacteria. Based on the presence of potential hemicellulases in their annotated genome, 4 culturable aerobic and nonpathogenic bacterial strains from marine (Pseudoalteromonas atlantica, Cellulophaga algicola), oligotropic (Caulobacter crescentus) and terrestrial (Paenibacillus sp. ) environment were selected. Of the 4 strains, P. Altantica was chosen for its culture supernatant appreciable activity towards fruit hemicelluloses. The secretomes were fractionated by ion-exchange chromatography to isolate β-glucanase, β- xylanase, β-xylosidase and α-arabinofuranosidase. The analysis of hydrolyzates revealed different substrate specificities, which together with structural analyses of isolated oligosaccharides provided novel insights of apple hemicelluloses complexity

Within the sediment, microbial communities play a pivotal role by driving essential processes such as nutrient cycling and organic matter degradation. Chronic hydrocarbons contamination represents almost 80% of the total input in the oceans. However, as compared to oil spills, its impact on microbial communities remains poorly understood. In this study, we first used a meta-analysis approach to decipher the global effect of hydrocarbons contamination in different habitats. Bacterial community response to the contamination was found to be dependant of the habitat studied, with soils being more impacted than other habitats, like marine sediments. Because bacteria are in interactions with other important members of microbial communities such as Archaea and Eukaryotes, we focused on microbial communities from the three domains of life in coastal marine sediments from the Mediterrranean and the French Atlantic coasts. Independently of the domains of life, chronic hydrocarbons contamination appeared to be a poor driver of communities structuration, and alpha diversity was not reduced in contaminated sediments. However, the comparison of co-occurences networks of contaminated and non-contaminated samples showed that the network from the contaminated samples exhibited a different topology, which suggests a higher vulnerability to eventual environmental perturbations. Potential indicators species identified using the meta-analysis approach were targeted to study the impact of chronic contamination on the ecological services they provide (i.e. organic matter and hydrocarbons degradation) using the Micro-FISH method
