The structures built during the Seventies present a significant reserve of resistance in spite of the local failures observed. The objective of this research task is the examination of the impact of the through cracks on metal offshore structures made up of welded tubes. The idea is to model at the total level the effect of a through crack using a criterion of the type evolution of total potential energy or evolution of the displacement of a strategic node of the structure. Indeed, these structures, conceived in the Seventies, are very redundant and profit from a reserve of significant integrity. All the dubious or random sizes, length of crack, loading of swell. . . , are modelled and integrated by approaches of the probabilistic types. One use for that the method of response surfaces by coupling the mechanical analysis (Rouhan 1999) and the requests (Schoefs 1996)

Traditionally, a scientist carries out experiments in a sequential way by varying the parameters the ones after the others. This method gives results but is very expensive in time because it inevitably requires the realization of a great number of experiments. This is why it is important to help the scientist to achieve his experiments with data analyses and experimental design methods. Data analysis makes it possible to collect, summarize and present data so as to optimize the way to implement next experiments. By using experimental design, the scientist knows how to plan experiments. This experimental step will help him to structure his research in a different way, to validate his own assumptions, with better understanding the studied phenomena, and to solve the problems. The objective of this thesis is to present, through examples of applications related to the development of deposits, the elaboration and the interest of these methods

Rapeseed and sunflower are the most cultivated oilseed plants in Europe in general, and in France in particular. Some industrialists are currently focusing on the development of industrial processes for the extraction/purification of proteins from the oil cakes of these two plants. These processes generate co-products which are saline aqueous effluents rich in phenolic compounds such as cholorgenic acid (CGA, for sunflower) and sinapine (SP, for rapeseed). The capture of these phenolic compounds, which can act as natural antioxidants and/or anti-inflammatory agents in nutrition and health, is therefore a promising way of valorization. The main objectives of this work were: 1) to characterize and identify the phenolic compounds of protein isolate by-products from SFM and RSM; 2) to select the best macroporous resins and to study the adsorption mechanism of phenolic compounds; 3) to optimize the conditions in the phenolic compounds adsorption column; and 4) to evaluate the biological activities of the obtained phenolic fractions, especially the antioxidant and anti-inflammatory properties.By different analytical methods, we determined that the liquid effluents consisted of phenolic compounds, amino acids, carbohydrates, and salt, which have a low molecular weight and can easily pass through a UF/DF membrane. All phenolic compounds were identified by HPLC and HPLC-ESI-MS analysis in comparison with standards. CGA is the main phenolic compound in the sunflower effluent. The main phenolic compound of rapeseed effluents is MS. Unlike sunflower, they also contain many other minor compounds. The adsorption/desorption of sunflower and rapeseed phenolic compounds was evaluated using different macroporous resins including XAD4, XAD7, XAD16, XAD1180 and HP20. We found that all phenolic compounds adsorbed readily onto the resins. XAD7 and XAD16 resins showed the best adsorption/desorption properties in sunflower and rapeseed liquid effluents, respectively. The results showed that the adsorption of all phenolic compounds follows a Langmuir model. According to the determined thermodynamic parameters, the adsorption process, is in all cases physical and is exothermic.The optimal condition for column adsorption was determined on the selected resins by experimental planning and multicriteria optimization. A multicriteria optimization methodology based on design of experiments showed the optimal conditions were adsorption flow rate of 15 BV/h at pH 2.7 for CGA from SFM. Meanwhile, adsorption flow rate of 13.3 BV/h and at pH ranging from 2 to 5 were the optimal conditions for sinapine from RSM. Ethanol solutions 50% (v/v) for chlorogenic acid, 70% (v/v) for sinapine were used for desorption.These approaches successfully produced the phenolic fractions for biological activities such as antioxidation and anti-inflammation. Phenolic fraction showed a higher antioxidant capacity than vitamin C in DPPH and ABTS assays (IC50/phenolic fractions < IC50 vitamin C, p < 0.05. In addition, it was discussed whether the phenolic fractions obtained in this project also showed an inflammatory effect. The sunflower fraction (CGA) effectively inhibited the production of TNF-α, which is a pro-inflammatory marker when a sample is treated with LPS. However, the rapeseed fractions were not effective against proinflammatory mediators. None of the fractions showed cytotoxicity

Plantain is a fruit commonly consumed in Congo - Brazzaville in its cooked form, as an accompaniment. The process of deep frying plantain is a widespread practice, often poorly mastered, given the prolonged use of frying oils, leading to the formation of compounds harmful to health. Indeed, for a number of years, the consumption of local oils (soybean, palm) and their degradation after heating are cause of major concern for consumer safety. The objectives of this study were to investigate the influences of the deep frying process applied on the Musa AAB plantain of "harton" variety, maturity level 7, as consumed in sliced form. We initially applied response surface methodology (RSM) to the deep frying process to determine the influence of three parameters (time / temperature / quantity) on different responses (color, hardness, oil uptake and water content) according to the type of oil used (soybean, palm, Frial oils). Once optimal conditions were obtained from the plantain in domestic conditions, the study focused on the evolution of frying oil stability, by monitoring physicochemical parameters of the degradation of the aforementioned (total polar compounds, free fatty acids, primary and secondary oxidation products). Analyses of color, crystallization point and viscosity, were added to the study and helped establish the optimal duration of use for these oils depending on the quantity of plantains fried. Lastly, the mechanisms of water transfer and oil uptake in the matrix has been studied and modeled according to temperature, thickness and immersion time

The quality by design (QbD) approach is a recent concept initiated by quality control which has led to new requirements from regulatory authorities, particularly in the pharmaceutical industry. Among these, the guideline ICHQ8 explains that quality should not be tested on finished products but should be integrated throughout, from design to finished product. This approach is characterised by different steps, one of which is risk assessment, which mainly involves identifying the critical parameters in a process or formulation. To do this, experiments must be carried out and suitable experimental designs will enable the phenomena studied to be modelled and then represent response surfaces in the experimental space to be explored. In this space, the Food and Drug Administration recommends delimiting a sub-space, called "Design Space", characterised by a certain probability that the output parameters comply with the specifications. This Design Space usually has any geometric shape, which means that the acceptable variation range of a parameter will depend on the value of another parameter. To overcome this constraint and thus define "Proven Acceptable Independent Range" for each parameter studied, we have used and adapted different methods. Their respective performance, in terms of defining acceptable variation range for each parameter independently, has been tested in different case studies
Malbert, Yannick. "Flavonoid glucodiversification with engineered sucrose-active enzymes." Thesis, Toulouse, INSA, 2014. http://www.theses.fr/2014ISAT0038/document.
Flavonoid glycosides are natural plant secondary metabolites exhibiting many physicochemical and biological properties. Glycosylation usually improves flavonoid solubility but access to flavonoid glycosides is limited by their low production levels in plants. In this thesis work, the focus was placed on the development of new glucodiversification routes of natural flavonoids by taking advantage of protein engineering. Two biochemically and structurally characterized recombinant transglucosylases, the amylosucrase from Neisseria polysaccharea and the α-(1→2) branching sucrase, a truncated form of the dextransucrase from L. Mesenteroides NRRL B-1299, were selected to attempt glucosylation of different flavonoids, synthesize new α-glucoside derivatives with original patterns of glucosylation and hopefully improved their water-solubility. First, a small-size library of amylosucrase variants showing mutations in their acceptor binding site was screened in the presence of sucrose (glucosyl donor) and luteolin acceptor. A screening procedure was developed. It allowed isolating several mutants improved for luteolin glucosylation and synthesizing of novel luteolin glucosides, which exhibited up to a 17,000-fold increase of solubility in water. To attempt glucosylation of other types of flavonoids, the α-(1→2) branching sucrase, naturally designed for acceptor reaction, was preferred. Experimental design and Response Surface Methodology were first used to optimize the production of soluble enzyme and avoid inclusion body formation. Five parameters were included in the design: culture duration, temperature and concentrations of glycerol, lactose inducer and glucose repressor. Using the predicted optimal conditions, 5740 U. L-1of culture of soluble enzyme were obtained in microtiter plates, while no activity was obtained in the soluble fraction when using the previously reported method of production. A structurally-guided approach, based on flavonoids monoglucosides docking in the enzyme active site, was then applied to identify mutagenesis targets and generate libraries of several thousand variants. They were screened using a rapid pH-based screening assay, implemented for this purpose. This allowed sorting out mutants still active on sucrose that were subsequently assayed for both quercetin and diosmetin glucosylation. A small set of 23 variants, constituting a platform of enzymes improved for the glucosylation of these two flavonoids was retained and evaluated for the glucosylation of a six distinct flavonoids. Remarkably, the promiscuity generated in this platform allowed isolating several variants much more efficient than the wild-type enzyme. They produced different glucosylation patterns, and provided valuable information to further design and improve flavonoid glucosylation enzymatic tools
