Suite aux travaux préalablement initiés au Laboratoire de Pharmacie industrielle et de Cosmétologie, nous nous sommes attachée à améliorer la connaissance de l'efficacité des différents filtres et écrans pouvant être utilisés actuellement dans les produits solaires. Notre travail a tout d'abord consisté en l'étude de l'efficacité des filtres dans le domaine UVA. On observe des niveaux d'efficacité variables selon les molécules utilisées. Le filtre le moins efficace est la benzophénone¬3. Le filtre UVA le plus efficace est en réalité un filtre à spectre large, à savoir l'anisotriazine. Côté photostabilité, on distinguera 2 catégories de filtres : ceux qui perdent plus de 10% de leur efficacité après deux heures d'irradiation (et c'est le cas pour la majorité des filtres étudiés) et ceux qui sont stables même après deux heures d'irradiation. Pour cette dernière catégorie, il s'agit des benzophénones 3 et 5, de la triazine commercialisée sous le nom de Tinosorb M® et du bisimidazylate. Ces filtres dont l'efficacité peut être bonne ou médiocre selon la molécule considérée présentent l'avantage d'être photostables, ce qui en fait des ingrédients de choix pour la formulation des produits solaires. Partant du principe qu'un produit solaire est un mélange de filtres et qu'il comporte, la plupart du temps, à la fois des filtres organiques et des filtres inorganiques, il nous a paru intéressant de tester l'effet de l'association des filtres entre eux sur le niveau de photoprotection obtenu. Des combinaisons filtres organiques – dioxyde de titane ou bien filtres organiques – oxyde de zinc ont été réalisées et ont permis de conclure à une meilleure synergie lorsque l'on associe les filtres organiques à l'oxyde de zinc. Si au regard de ces résultats, il semble plus simple d'associer l'oxyde de zinc que le dioxyde de titane, il faut toutefois bien noter que les associations incluant du dioxyde de titane permettent d'atteindre des niveaux de photoprotection beaucoup plus élevés. La meilleure association est celle avec l'anisotriazine puisque l'on obtient un SPF supérieur à 50
Following the work initiated in the Laboratory of industrial Pharmacy and Cosmetology, we tried to increase our knowledge on the efficacy of different filters organic and inorganic used in suncare products. First of all we studied the efficacy of the filters in the UVA range. Depending on the molecules used we observed a range of results in terms of efficacy. The less efficient is the benzophenone¬3. The best UVA filter which has a wide spectrum is the anisotriazine. In terms of photostability, we will distinguish 2 categories of sun filters: the ones which are loosing more than 10% of their efficacy after 2 hours irradiation (it is the case for the majority of the filters studied) and the ones which are stable even if after 2 hours irradiation. This last category groups the benzophenone 3 and 5, the triazine sold under the name Tinosorb® S and the bismidazylate. The pros of those sun filters, which are efficient or not depending on the molecule, is their photostabilty. In fact, they will be the first choice to formulate sunscreens with. Knowing that a suncare product is a combination of different filters organic and inorganic, we decided to test their association against the photoprotection obtained. Associations between organic and inorganic filters, such as titanium dioxide or zinc oxide, have been done. The best synergy is obtained when organic sun filters are combined with zinc oxide. Regarding those results, zinc oxide is easier to combine than titanium dioxide with other filters. However, the combinations with titanium dioxide result in higher photoprotection. The best combination is with the anisotriazine, as the SPF obtained is higher than 50

Les produits pétroliers formulés actuels tels que les carburants et les lubrifiants doiventrépondre à des cahiers des charges bien précis pour garantir les meilleures performances,fiabilité et longévité des moteurs tout en limitant l’émission de polluants. Ce travail de thèse porte sur le développement de méthodologies d’analyse pour l’identification d’additifs polymériques dans les gazoles et la caractérisation des polyalphaoléfines. L’analyse des additifs a été effectuée par couplage de la chromatographie liquide, de la spectrométrie de mobilité ionique et de la spectrométrie de masse (LC-IMSMS), l’ionisation étant obtenue par electrospray (ESI). Après ajustement des paramètres expérimentaux, les différents additifs ont été identifiés dans les gazoles sans préparation d'échantillon. Le couplage de la chromatographie liquide aux conditions critiques (LCCC) avec la spectrométrie de masse a également été évalué dans l’objectif d’améliorer la séparation des additifs de la matrice gazole. La caractérisation des polyalphaoléfines (PAO) a été réalisée par couplage IMS-MS associé à la source ASAP (sonde d’analyse de solide à pression atmosphérique) ou la source APPI (photoionisation à pression atmosphérique). En ASAP, outre les ions de pyrolyse, des espèces intactes peuvent être détectées pour les PAO de faible grade. Dans le cas des PAO de haut grade, seuls des ions fragments pyrolytiques ont été détectés, permettant toutefois d’identifier les alpha-oléfines utilisées pour produire les PAOs. En APPI, l’utilisation de solvants halogénés et de toluène, a permis d’observer des espèces intactes pour les PAOs de haut grade via la formation d’adduits halogénés. Le couplage IMS-MS a permis de différencier les polyalphaoléfines par l’étude des temps de dérive et des largeurs de signaux IMS
Nowadays, formulated petroleum products such as fuels and lubricants must respond toprecise technical requirements to ensure the best performance, reliability and longevity ofengines while limiting the emission of pollutants. This thesis work focused on the development of analytical methodologies for the identification of polymeric additives in diesel fuels and the characterization of polyalphaolefins. The additive analysis was performed by coupling of liquid chromatography, ion mobility spectrometry and mass spectrometry (LC-IMS-MS), the ionization was performed by electrospray (ESI). After adjusting the experimental parameters, all additives were identified in the diesel fuel without sample preparation. The coupling of liquid chromatography at the critical condition chromatography (LCCC) with mass spectrometry was also evaluated in order to improve the separation of additives from the diesel fuel matrix. The characterization of polyalphaolefins (PAO) was carried out by IMS-MS with ASAP (atmospheric solids analysis probe) or APPI (atmospheric pressure photoionization) sources. With ASAP, in addition to pyrolysis ions, intact species were detected for low PAO grades. In the case of high PAO grades, only pyrolytic fragments were detected, yet it was possible to identify the alphaolefins used to produce the PAOs. In APPI, the use of halogenated solvents and toluene, allowed to observe intact species for high PAO grades through the formation of halogenated adducts. With IMS-MS coupling polyalphaolefins were differentiated the by the study of drift times and full width at half maximum

Ces travaux de recherche ont pour objectif de développer une méthodologie en vue d'optimiser les conditions opératoires d'un procédé de polymérisation en émulsion, permettant de synthétiser des latex possédant des propriétés d'usage ciblées. Les propriétés suivies sont celles des particules de latex (morphologie, composition chimique) et celles des films formés à partir de ces dernières (module élastique, composition, topologie, température minimale de formation du· film). Une importance particulière est accordée aux propriétés des latex utilisés pour des applications dans le domaine des peintures. La résistance à l'abrasion humide de ces peintures constitue une propriété déterminante. Dans un premier temps, une synthèse bibliographique aborde les notions de base nécessaires à la compréhension du sujet. Les principes de la polymérisation en émulsion sont détaillés, de même que les phénomènes intervenant lors de la formation du film à partir d'un latex. Par ailleurs, le contrôle de la morphologie des particules est abordé. Enfin, quelques notions relatives aux applications des latex en peinture sont présentées. Puis, après l'exposé les techniques expérimentales utilisées, une méthodologie expérimentale originale est mise en place. L'objectif de cette méthodologie vise à définir l'influence des caractéristiques physicochimiques des particules de latex sur leurs propriétés d'usage. La stratégie expérimentale mise alors au point consiste d'abord à détem1iner les principales caractéristiques physicochimiques des particules de latex ou facteurs influençant les propriétés d'usage. Par la suite, un plan d'expériences de ces facteurs a été optimisé grâce à l'utilisation des concepts de D-optimalité et d'isovariance par rotation. Un logiciel comprenant un modèle cinétique de copolymérisation, qu'il a fallu élaborer, ainsi qu'un algorithme évolutionnaire, ont permis de fixer les conditions opératoires du procédé permettant de mener à bien les synthèses des latex du plan d’expériences. Cette opération s'est déroulée suivant une procédure établie et vérifiée expérimentalement. La méthodologie a ensuite été appliquée à l'étude de latex composés de particules structurées ayant une morphologie de type cœur/écorce. L'analyse des propriétés d'usage des produits synthétisés a enfin permis d'aboutir à la définition des caractéristiques physicochin1iques optimales des latex et à la mise au point des conditions opératoires à mettre en œuvre pour les obtenir
The aim of this study is to develop a methodology in order to optimize the pararneters of an emulsion polymerization process, so as to synthesize latexes with defined properties. The properties that are to be determined are those of the particles (composition, morphology), and those of the film Formed using the latex (Young's modulus, composition, topology, minimum film formation temperature). The main application field of the latexes concerns paints. Consequently, the web scrub resistance of the paints is a determining property. Firstly, a literature study is carriecl out about the principles of the emulsion polymerization, and the film formation. Besicles, the control of the particle morphology is developed. The latexes that are studied will be used to enter in the formulation of paints. Therefore, the composition of the paints and the main properties of the paint films are explained. After presenting the experimental techniques that are used in this study, a new experimental methodology is developed. It aims at understanding the influence of the physical and chemical properties of the latex particles on the application properties of the latex. The experimental strategy consists fïrstly in determining the particle characteristics that control the latex properties when used as films or formulatecl in paints. Afterwards, an experimental strategy is designed for the elaboration of latexes having different properties. The concepts of D-optimality and rotatability are used so as to realise this design. The following step of this experimental strategy is to define the process parameters (temperature, feecl composition and feed flow rates) that have to be applied in order to synthesize each latex. In that purpose, a software has been completed with a kinetic model of the process and a optimization algorithm (evolutionary algorithm). Besicles, a procedure has been defined and validatecl with experiments. In thiswork, the tools used to delevelop the experimental methodology are defined and set. Then, the strategy of experiments is applied to latexes composed with core / shell particles. The analysis of the properties of the latexes allowed to defined the optimal physical and chemical characteristics of the latexes and, finally, the operating experimental conditions to obtain them. The latexes were formulated in paints, and the physical properties of the paints were linked to the characteristics of the latex particles

Le génie des produits formulés propose une démarche pour essayer de comprendre et contrôler le lien entre les propriétés micro-, méso- et macroscopiques d'un produit fini. Dans cette démarche, la compréhension du comportement global du produit nécessite la caractérisation de ses trois échelles constitutives, afin de maîtriser ses propriétés d'usage et pouvoir remplir un cahier de charges (généralement imposé). Cette approche s'adapte à l'étude des systèmes hors-équilibre et à plusieurs composants. Les émulsions de Pickering, ou émulsions stabilisées avec des particules solides, représentent un terrain expérimental riche pour utiliser cette approche. Dans le cadre de cette thèse, nous avons travaillé avec des particules de silice commerciales pour stabiliser les émulsions. La taille et la mouillabilité des particules ont été caractérisées. La nature des émulsions pouvait être directe inverse eau-dans-huile ou directe huile-dans-eau. De plus, nous avons testé trois agitateurs différents : turbine Rushton, rotor-stator et sonde à ultrasons pour les préparer. Les caractérisations systématiques des émulsions concernaient la taille de goutte moyenne, le comportement rhéologique et la répartition des particules de silice entre les interfaces liquide/liquide et la phase continue. Nous avons trouvé que le couplage composition-procédé permettait de contrôler ces propriétés. Dans un premier temps, nous nous sommes intéressés aux émulsions inverses et directes préparées avec un même procédé d'émulsification. Dans un deuxième temps, nous avons proposé une étude systématique d'émulsions directes préparées principalement avec deux procédés d'émulsification. Et dans un dernier temps, nous avons essayé de pousser les limites de la composition de ces émulsions ainsi qu'une modélisation de leur comportement rhéologique
The chemical product design approach tries to understand and control the link between the micro-, meso- and macroscopic properties of a finished product. In this approach, the understanding of the global behavior of the product requires the characterization of its three constitutive scales, in order to control its end-use properties and to be able to fulfill a specification, which is generally imposed. This approach is adapted to the study of non-equilibrium and multi-component systems. Pickering emulsions, or particle-stabilized emulsions, are a rich experimental field to apply this approach. In this thesis, we worked with commercial silica particles to stabilize the emulsions. The size and wettability of the particles were characterized. The nature of the emulsions could be direct reverse water-in-oil or direct oil-in-water. In addition, we tested three different stirrers: Rushton turbine, rotor-stator and ultrasonic probe to prepare them. Systematic characterizations of the emulsions concerned the average drop size, the rheological behavior and partitionning of the silica particles between the liquid/liquid interfaces and the continuous phase. We found that the composition-process coupling allowed to control these properties. In a first step, we focused on reverse and direct emulsions prepared with the same emulsification process. In a second step, we proposed a systematic study of direct emulsions prepared mainly with two emulsification processes. And in a third time, we tried to push the limits of the dispersed phase fraction of these emulsions as well as a modeling of their rheological behavior

Cette thèse vise à développer des formules cosmétiques éco-responsables à faible nombre d’ingrédients, en lien avec le contexte actuel du « Clean-label » dans ce secteur. Nous nous sommes intéressés à des dispersions de particules d’huile gélifiée, nommées « dispersions de gélosomes », encore inexplorées pour une utilisation cosmétique. Connues pour être stables et capables d’encapsuler des actifs hydrophobe, la question de leur texture et de leur application sur la surface de la peau reste aujourd’hui non renseignée. Elles sont préparées par émulsification à chaud d’un organogel, composé d’huile et de gélifiant lipophile (acide 12-hydroxystéarique), en présence d’un agent stabilisant (alcool polyvinylique hydrolysé à 80%). L’émulsion formée conduit, après refroidissement, à une dispersion de particules d’organogel. Nous avons d’abord démontré la possibilité de réaliser des dispersions de gélosomes avec des huiles cosmétiques et un conservateur. Des textures très variées ont été obtenues allant de liquides fluides à des gels fermes et cassants. L’analyse physico-chimique et l’observation microscopique de ces nouvelles formules ont permis d’identifier leurs microstructures : dans certaines conditions, des connexions se forment entre les gélosomes, et un hydrogel colloïdal est obtenu. L’étude des interactions à l’interface a permis de déterminer les facteurs et les mécanismes menant à des gélosomes individualisés ou connectés. Les dispersions de gélosomes, même les plus fluides, ont montré une grande stabilité. Enfin, de nouvelles dispersions de gélosomes ont pu être formulées à partir de stabilisants de nature et de modes de stabilisation variés. La méthodologie employée au cours de ce travail a permis d’établir un lien entre le stabilisant et les propriétés des dispersions. Des mécanismes différents ont pu être identifiés, induisant des microstructures et des propriétés applicatives intéressantes et variées. Pour la première fois, les propriétés de texture des dispersions, caractéristiques d’une application topique ont été collectées sur l’ensemble des systèmes par une approche combinée d’analyses rhéologiques in vitro et d’analyses sensorielles in vivo ; les perceptions ont été décrites et explicitées en fonction de l’influence de la nature de l’huile, du stabilisant et du type de microstructure
This thesis aims to develop eco-responsible cosmetic formulas with a low number of ingredients, in line with the current context of “Clean-label” in this sector. We focused on dispersions of gelled oil particles, called “gelosome dispersions”, which have not yet been explored for cosmetic use. Known to be stable and capable of encapsulating hydrophobic active ingredients, the question of their texture and their application onto the surface of the skin remains unanswered to date. They are prepared by hot emulsification of an organogel, composed of oil and a lipophilic gelator (12-hydroxystearic acid), in the presence of a stabilizing agent (80% hydrolyzed polyvinyl alcohol). Upon cooling, the emulsion leads to a dispersion of organogel particles. We first demonstrated the possibility of making gelosome dispersions with cosmetic oils and a preservative. A wide variety of textures was obtained, ranging from fluid liquids to firm and brittle gels. Physicochemical analysis and microscopic observation of these new formulas made it possible to identify their microstructures: under certain conditions, connections are formed between the gelosomes, and a colloidal hydrogel is obtained. The factors and mechanisms leading to individualized or connected gelosomes were determined by the study of interactions at the interface. Gelosome dispersions, even the most fluid, showed great stability. Finally, new dispersions of gelosomes were formulated using stabilizers of various types and stabilization modes. The methodology used during this work enabled the establishment of a link between the stabilizer and the properties of the dispersions. Different mechanisms could be identified, inducing interesting and varied microstructures and application properties. For the first time, the texture properties of the dispersions, characteristic of a topical application, were collected across all systems using a combined approach of in vitro rheological analyzes and in vivo sensory analyses; the perceptions were described and explained according to the influence of the nature of the oil, the stabilizer and the type of microstructure

There is a formula by the string theorists Dijkgraaf, Moore, Verlinde and Verlinde, expressing the orbifold elliptic genus of the symmetric powers of an almost complex manifold M in terms of the elliptic genus of M itself. We show that from the point of view of elliptic cohomology an analogous p-typical statement follows as an easy corollary from the fact that the map of spectra corresponding to the genus preserves power operations. We define higher chromatic versions of the notion of orbifold genus, involving h-tuples rather than pairs of commuting elements. Using homotopy theoretic methods we are able to prove an integrality result and show that our definition is independent of the representation of the orbifold. Our setup is so simple, that it allows us to prove DMVV-type product formulas for these higher chromatic orbifold genera in the same way that the product formula for the topological Todd genus is proved. More precisely, we show that any genus induced by an H[omega]-map into one of the Morava-Lubin-Tate cohomology theories Eh has such a product formula and that the formula depends only on h and not on the genus. Since the complex H[omega]-genera into Eh have been classified in [And95], a large family of genera to which our results apply is completely understood. Loosely speaking, our result says that some Borcherds lifts have a well-known homotopy theoretic refinement, namely total symmetric powers in elliptic cohomology.

A partir d'un terrain mené dans une grande banque d'investissement française, cette thèse étudie la mise en marché d'une nouvelle classe de produits financiers - les produits à capital garanti - en suivant, des salles de classes aux salles de marché, les formules qui font ces produits. Ce sont ces formules qui sont les fils conducteurs de cette ethno-économie : elles donnent accès aux techniques pédagogiques déployées pour saisir leurs spécificités, elles font entrer dans les techniques de vente propres à ces produits et elles éclairent les difficultés rencontrées par une organisation marchande tiraillée entre différents impératifs. Le succès de ces produits financiers exposent le capital de la banque à la prédation des autres grandes banques. Par son approche ethnographique, cette étude contribue à la nouvelle anthropologie de l'économie mais elle éclaire aussi la question des rapports entre le capital financier et le capital industriel
Using a fieldwork in a french investment bank, this research studies the way to the market of a new class of financial products - the capital garantee product - by following the formulas that make the products, from the classroom to the trading room. The formulas pave the way to this ethno economy : they give access to the pedagogical techniques used to grasp their specificity, they open up the realm of the sale techniques necessary to circulate these products and they highlight the difficulties met by an organisation under the pressure of different imperatives. The success of the capital garantee products threaten the capital of the bank. Through its ethnographic approach, this study belongs to the new anthropology of the economy but it also highlights the question of the relationship between finance capital and industrial capital

Avec les progrés opérés depuis quelques années dans le domaine de la synthèse chimique et les performances nouvelles générées, à la fois par la chimie combiantoire et les études de en plus sophistiquées de "screening" de molécules nouvelles, la Recherche et Développement Pharmaceutique se trouve très fréquemment confrontée à la formulation de principes actifs à très faible solubilité aqueuse et pour lesquels, cliniciens et services de marketing souhaitent mettre au point et commercialiser des formes solides pour administration par voie orale. Dans le contexte de la gestion de la qualité pharmaceutique, cette problématique oblige le formulateur à concevoir des formules et/ou proposer de nouveaux procédés de mise en forme. Ainsi, et pour un composant actif donné, les études de pré-formulation, essentiellement basées sur la sélectionqualitative d'excipients fonctionnels, puis les études de formulation considérant la définition quantitative de ces substances auxiliaires pour élaborer une forme de présentation donnée, obligent les acteurs du Développement à considerer une approche couplée Produit/Procédé. Dans cet esprit du Génie des produis formulés, l'objectif essentiel de cette étude, est, à partir d'un composant actif modèle, reconnu pour sa faible capacité à se solubiliser dans l'eau (l'ibuprofène) de développer des microparticules formulées permettant d'améliorer sa vitesse de dissolution en faisant appel à un procédé robuste, prenant en compte la protection de l'environnement, respectant les bonnes pratiques de fabrication et par ailleurs, économiquement applicable. Ainsi, une étude de mélanges physiques, puis celle du broyage, de l'évaporation de solvant et enfin de l'atomisation de suspensions actives en phase liquide majoritairement aqueuse a été menée. Des travaux réalisés, il ressort que l'amélioration de la vitesse de dissolution de l'ibuprofène dépend de la nature des adjuvantes de formulation et des méthodes de préparation utilisées. Dans les conditions expérimentales testées, nous avons pu démontrer tout l'intérêt de la valorisation du procédé d'atomisation, pour fournir des microparticules de morphologie et de granulométrie maîtrisées et présentant par ailleurs une aptitude à la dissolution in vitro qualifiée de rapide, comparativement à la matière actif originelle. Les performances de l'atomisation et la qualité des atomisats développées sont cependant très variables et dépendent : du type de surfactant et d'agent de séchage, mais également des paramètres propres au procédé (température notamment). Parmi les agents de séchage sélectionnées, nous avons pu dégager l'intérêt de l'utilisation de l'Aerosil 200® et tout particulièrement sa fonctionnalité à fournir des rendements de production satisfaisants. Pour ce qui est de l'utilisation de surfactants, les matières grasses gras (Tween 80®) se sont révélées peu efficaces comparativement aux surfactants solides de type lauryl sulfate de sodium et cétrimide. Pour ce qui est de la partie propre au procédé, il a été mis en évidence un intérêt à retenir et valorises le procédé d'atomisation pour ce type de production, intérêt que nous avons démontré, par une étude chimiométrique en plans d'expériences et une approche de transposition d'échelle sur un équipement pilote.

A covariant Wigner-Weyl quantization formalism on the manifold that uses pseudo-differential operators is proposed. The asymptotic product formula that leads to the symbol calculus in the presence of gauge and gravitational fields is presented. The new definition is used to get covariant differential operators from momentum polynomial symbols. A covariant Wigner function is defined and shown to give gauge-invariant results for the Landau problem. An example of the covariant Wigner function on the 2-sphere is also included.

Pendant la phase de conception, 80 % des coûts d'un produit sont engagés par les décisions prises par les concepteurs. De plus, c'est durant cette phase que les possibilités de réduire son coût total sont les plus importantes et que les possibilités d'étude des solutions alternatives et des modifications sont les moins onéreuses. Or, en phase de conception, la définition du produit n'est que partielle, et les conditions et les moyens de production quasiment inconnus. Il est donc essentiel de fournir aux concepteurs des outils d'estimation de coûts efficaces, adaptés à ses connaissances sur le produit, et intégrant l'expertise et les connaissances "métier" de l'entreprise. Après avoir souligné les limites des outils traditionnels d'évaluation économique en phase de conception, le travail réalisé dans cette étude vise à formaliser et à valider une démarche de création d'outils d'estimation de coût spécifiques, intermédiaires aux modèles universels et aux modèles analytiques. L'approche est basée sur la méthode paramétrique des formules d'estimation de coût (FEC) dont le principe général est de fournir des relations mathématiques reliant le coût d'un produit à certains de ses paramètres techniques descripteurs. Dans notre travail, nous avons particulièrement développé les points suivants : 1 - le développement de l'ensemble de la méthodologie de création de modèles spécifiques d'estimation de coûts, depuis la définition du cadre de l'étude et la récupération de données jusqu'à la sélection de formules et leur validation. 2 - l'utilisation de paramètres descripteurs de coût originaux palliant au problème de l'estimation du coût d'un produit partiellement défini. 3 - la mise au point de méthodes de sélection de formules ayant le meilleur compromis qualité statistique/cohérence technique. Enfin, ces différentes approches ont été testées sur une application réelle, l'usinage de pièces prismatiques
Eighty per cent of the costs of a product are detemined by decisions taken by the designers. Moreover, it is during the design phase that possibilities of reducing the total cost are the most important. Early studies of alternative solutions and design modifications are less expensive and more efficient. However, in the design phase, the product is never completely defined and the conditions and means of production are note fully known. Therefore, it is necessary to provide the designer with efficient cost estimation tools adapted to the available knowledge about the product, and including the expertise and the experience of the compagny. After having emphasized the limits of traditional tools for the economic evaluation during design phase, the objective of this work is to formalize and validate the processes for the creation of specific cost estimation tools, which are intermediary between universal models and analytic methods. The approach is based on the parametric method using cost estimation relationship (CER) which model the cost of a product according to some of its technical descriptor parameters. In this work, we have developed the following topics : 1 - the methodology for the creation of specific cost estimation tools, from the definiton of the scope of the study, the collection of data, to the selection of formulae and their validation. 2 - the definiton of new cost drivers palliating to the cost estimation problem of a partially defined product. 3 - practical methods for the selection of cost estimation relationships taking into account the statistical quality criteria and the technical coherence. These approaches have been tested and validated on a real project, the estimation of manufacturing cost for prismatic parts

La programmation des maladies non transmissibles est désormais un paradigme établi. Les événements indésirables encourus au cours de la vie foetale peuvent affecter le développement du foetus et sa santé future. Ce risque de pathologies à l'âge adulte est majoré lorsqu'il est associé à un environnement défavorable. Plusieurs arguments scientifiques viennent étayer le rôle des contaminants alimentaires dans les processus de la programmation développementale. Parmi ces contaminants, aucune mention n'est faite aux produits de la glycation issus des traitements thermiques des aliments et dont l'implication dans les désordres métaboliques et rénaux et dans le vieillissement est largement connue. Afin de vérifier leur implication dans la programmation du stress oxydant et de l'inflammation, nous avons administré à des porcs RCIU deux formules laitières. Une formule fortement chauffée à 120°C pendant 10 minutes (HHF) et une formule faiblement chauffée à 37°C pendant 5 minutes (LHF).Nous avons montré que la consommation de la formule HHF induit: 1) l'augmentation de la CML libre dans le sang des porcelets nourris avec ce régime ; 2) la présence d'un marquage de la CML dans les noyaux des cellules épithéliales rénales. Cette présence a également été observée dans les reins des animaux nourris avec le régime LHF mais pas chez les porcs allaités ; 3) une activation du récepteur soluble RAGE et l'augmentation de l'expression de gènes du système rénine-angiotensine, de l'inflammation, de l'apoptose ainsi que de l'oxydation des protéines dans le rein et dans le foie ; 4) des modifications importantes dans l'expression et le niveau d'activité de certaines enzymes antioxydantes dans le foie et le rein. Ces effets à long terme de la consommation postnatale de la formule HHF témoignent incontestablement d'un phénomène de programmation du système oxydant et de l'inflammation. Au niveau du colon, la formule HHF a contribué à l'augmentation transitoire des Bifidobactéries et des bactéries lactiques et à l'activation d'enzymes antioxydantes, démontrant le rôle joué par le microbiote intestinal dans la défense contre la présence des AGEs alimentaires pro-oxydants. Des études impliquant le MG dans les processus de programmation foetale ont été initiées sur le modèle rongeur. Elles montrent que le MG module la sécrétion d'insuline pancréatique de la descendance à l'âge adulte. Au regard de ces résultats, ce travail apporte des preuves nouvelles sur l'implication des AGEs alimentaires dans les processus de programmation développementale et souligne l'importance du contrôle de la présence de ces composés dans l'alimentation de la mère et de l'enfant
Programming of non-communicable diseases is now a well-established paradigm. Adverse events occurring during fetal life can affect fetal development and future health. This risk of disease in adulthood is increased in unfavorable environments. Several scientific studies support the role of dietary contaminants in developmental programming. Among these contaminants, no mention is made of glycation end products generated by heat treatment, which are largely implicated in metabolic disorders, kidney disorders and aging. In order to test their possible involvement in the programming of oxidative stress and inflammation, we administered two dairy formulas to IUGR pigs. First, a formula heated at 120 °C for 10 minutes (High Heated Formula: HHF), followed by a formula heated at 37 °C for 5 minutes (Low Heated Formula: LHF). We showed that the consumption of HHF formula did the following: 1) induced an increase in the level of free CML in the blood of IUGR animals during artificial suckling. 2) Resulted in the labelling of CML in the nuclei of renal epithelial cells. This labelling has also been detected in kidneys of animals fed with the LHF formula, but not in the kidneys of natural suckling piglets. 3) Activation of the soluble RAGE receptor, an increase in gene expression of the renin-angiotensin system, and an increase in inflammation, apoptosis and protein oxidation in the kidney and liver. 4) Significant changes in the expression and activity levels of certain antioxidant enzymes in the liver and kidney. These long-term effects of postnatal consumption of HHF formula undoubtedly demonstrate a programming phenomenon of oxidative stress and inflammation. In the colon, the HHF formula contributed to the transient increase in Bifidobacteria and Lactobacilli, and the activation of antioxidant enzymes, demonstrating the role of the gut microbiota in the defense against the presence of dietary pro-oxidant AGEs. Studies involving the ethyglyoxal the fetal programming process were initiated in the rodent model. They show that the MG modulates the secretion of pancreatic insulin by progeny during adulthood. In view of these results, this work provides new evidence for the involvement of dietary AGEs in the developmental programming process, and underlines the importance of controlling the presence of these compounds in the diet of both the mother and child

Les petits groupes de conception de produits technoculturels interviennent dans un secteur où règnent des contraintes économiques fortes et dans lequel la quête du succès suppose de faire des choix entre la reproduction de formules éprouvées et la conception de produits nouveaux. La première option qui permet d'augmenter les chances de succès au prix d'investissements lourds, se distingue de la seconde qui s'accommodent de moyens plus modestes au prix d'un risque d'échec accru. Les produits sur lesquels portent notre recherche, la musique enregistrée et les jeux video, sont de plus en plus complexes à concevoir et demandant un éventail de compétences qui les met hors de portée du créateur individuel, nécessitant des équipes qui rassemblent des connaissances et des compétences très variées (artistiques, techniques, financières, organisationnelles, communicationnelles, etc. ). Si la reproduction de formules éprouvées-permet la mobilisation de procédures déjà connues, chaque création d’un produit intégrant une importante part de nouveauté est une incursion dans l'inconnu. L'objet de notre recherche consiste, après avoir consisté que nouveauté échappe à l'approche algorithmique, à voir de quelle façon les groupes chargés de la réalisation de tels produits peuvent gérer l'émergence de la nouveauté en leur sein. Nous proposons une méthodologie d'évaluation de l'émergence de nouveauté et traçons des pistes pour une nouvelle approche opérationnelle de la créativité de groupe.

Dissertação de Mestrado Integrado em Medicina Veterinária
Anthelmintic resistance in horses has increased in recent years and the continuous search for alternative control methods has led to the development of complementary approaches such as biological control. This approach can make use of parasiticide fungi, such as Duddingtonia flagrans and Mucor circinelloides, in parasite population control and recent research has been focused on the development of new administration methods. Following this line of research, a new and alternative formula has been developed by using a lyophilized product that contained both D. flagrans and M. circinelloides spores for the control of gastrointestinal nematodes in horses. After the product manufacture and the normal spore morphology were assessed, these were tested for in vitro growth. A total of 20 Petri dishes were assembled with a mix of 0.1 g of product and 0.5 ml of water in solid media. The assembled plaques were kept at 25ºC in total darkness and all showed the development of new fungi spores after 10 days. Following the in vitro assessment, the product was administered per os to horses in order to observe their effect in the faecal egg count (FEC) of eggs per gram (EPG). Thus, one group of 5 horses in a pasture was chosen to receive 10 g of product (with M. circinelloides spores and a total of around 105 D. flagrans chlamydospores per horse), 3 days a week starting in September, and another group of 7 horses in an adjacent pasture remained as control. Following treatment with Ivermectin pour-on in September 2017, a faecal sample was collected from each horse on a monthly basis and FEC was assessed using a Modified McMaster technique. Only gastrointestinal nematode eggs, namely strongyle eggs, were observed with this technique. The EPG average from each group was compared for each individual month and overall to see the reduction effect achieved with the fungi treatment. Statistically significant differences were found between the two groups in February (72% reduction), March (64% reduction), and overall, 66% reduction. The horses in the test group only reached a cut-off value of 300 EPG two months after the horses in the control group. In November and January, faecal culture method was applied to all faecal samples, showing only the presence of cyathostomin larvae. This study allowed the successful development of a new formula for the administration of parasiticide fungi to horses, based on lyophilized product, which increases the possibilities for future product development and application. New and improved ways of biological control should be developed and implemented to increase parasite control and reduce anthelmintic resistance cases.
RESUMO - NOVA FÓRMULA DE ADMINISTRAÇÃO DE FUNGOS PARASITICIDAS PARA PREVENIR INFEÇÃO POR NEMÁTODES GASTROINTESTINAIS EM CAVALOS DE PASTOREIO (LUGO, ESPANHA) - A resistência a anti-helmínticos em cavalos tem vindo a aumentar recentemente e a procura por métodos de controlo alternativos levou ao desenvolvimento de abordagens complementares como o controlo biológico. Esta abordagem usa fungos parasiticidas, como Duddingtonia flagrans e Mucor circinelloides, no controlo da população parasitária e estudos recentes têm-se focado no desenvolvimento de novos métodos de administração. Seguindo esta tendência, uma fórmula nova e alternativa foi desenvolvida utilizando um produto liofilizado que contém esporos de D. flagrans e M. circinelloides para o controlo de nematodes gastrointestinais em cavalos. Após fabrico do produto e verificação da morfologia normal dos esporos, estes foram testados para crescimento in vitro. Um total de 20 placas de Petri foram semeadas com uma mistura de 0.1 g de produto e 0.5 ml de água em meio sólido. As placas foram mantidas a 25ºC em escuridão total e todas demonstraram desenvolvimento de novos esporos passados 10 dias. Após a verificação in vitro, o produto foi administrado per os a cavalos para observar o seu efeito nas contagens fecais de ovos (CFO) por grama (OPG). Assim, um grupo de 5 cavalos em pastoreio foi escolhido para receber 10 g de produto cada (com esporos de M. circinelloides e um total de cerca 105 clamidosporos de D. flagrans por cavalo) 3 vezes por semana, de setembro a março. Outro grupo de 7 cavalos numa pastagem adjacente foi utilizado como controlo. Após tratamento com unção contínua de Ivermectina em setembro de 2017, uma amostra fecal de cada cavalo foi colhida mensalmente e o CFO foi avaliado utilizando a técnica de McMaster modificado. Apenas ovos de nemátodes gastrointestinais, nomeadamente estrongilídeos, foram observados com esta técnica. A média de OPG de cada grupo foi comparada para cada mês e no total do estudo para observar o efeito de redução do tratamento fúngico. Diferenças estatisticamente significativas entre os dois grupos foram observadas em fevereiro, redução de 72%, março, redução de 64%, e no total, 66% de redução. Cavalos no grupo de teste só passaram o limiar de 300 OPG dois meses depois dos cavalos do grupo controlo. Em novembro e janeiro foram realizadas culturas fecais em todas as amostras, demonstrando apenas a existência de larvas de ciatostomíneos. Este estudo permitiu com sucesso o desenvolvimento de uma nova fórmula para administração oral de fungos parasiticidas para cavalos com base num produto liofilizado, aumentando as futuras possibilidades de desenvolvimento e aplicações de produtos. Novas e aperfeiçoadas formas de controlo biológico devem ser desenvolvidas e implementadas para aumentar o controlo de parasitas e diminuir os casos de resistência a anti-helmínticos.

Dans ce travail on caractérise l'image de Fourier de plusieurs espaces de distributions sur certains groupes de Lie et on donne des applications. Les théorèmes de Paley-Wiener sont décrits par rapport à une famille fondamentale de compacts et d'opérateurs de multiplication. Ces objets sont construits via une fonction sous-multiplicative propre continue. L'espace de Paley-Wiener des distributions à support compact devient donc l'espace des opérateurs sur un espace de type Sobolev, vérifiant quelques propriétés. Les théorèmes de Paley-Wiener sur l'espace des fonctions indéfiniment différentiables à support compact (resp sur l'algèbre des fonctions de carrés intégrables a support compact) sont étudiés. Pour des cas particuliers de groupes de Lie, des simplifications interviennent et les opérateurs étudiés sont alors de Hilbert-Schmidt. On donne ensuite une formule de Plancherel sur le produit semi-direct de groupes et par conséquent nous étudions la résolubilité locale d'une classe d'opérateurs différentiels. La notion de p-convexité et "surjectivité" d'une famille d'opérateurs différentiels est aussi étudiée. Enfin à partir d'une formule de Kirillov sur les nilpotents, nous étudions certains caractères sur ces groupes.

As the world's most populous country, with more than 16 million births every year, China has emerged as a large importer of baby formula. China's relaxation of the one-child policy, which was announced in 2015, is expected to increase the number of births significantly and therefore increase the demand for Chinese and imported baby formula. While information on parent preferences for baby formula is very important for understanding and predicting China's import demand for baby formula and other products used to produce baby formula, like milk powder, there are very limited empirical studies on Chinese parent preferences for baby formula in the literature due to data limitation and other reasons. This research collects primary data from China through a parent survey, uses the data to analyze parent preferences and willingness to pay (WTP) for selected baby formula attributes, and derives implications for U.S. dairy product exports. Specifically, with detailed data from a total of 433 respondents, this study first examines parent purchase behavior of baby formula through descriptive analysis, then assesses parent preferences and WTP for selected baby formula attributes through the estimation of a random utility model, and finally derives implications for U.S. exports of milk powder, whey, and other dairy products. The descriptive analysis suggests that education level and income play an important role in parent purchase behavior of baby formula. The estimation results of the random utility model differed according to whether the survey was administered online or as a hardcopy. The results from the online survey indicate that imported, organic, and more reputable brands of baby formula are more attractive to respondents than domestic, non-organic, and less reputable brands. While respondents who completed the hardcopy survey also indicated a preference for organic baby formula from a reputable brand, they preferred domestic baby formula to imported formula. Further analysis of the WTP from the online survey for baby formula showed that parents have a strong preference and are willing to pay significantly more for baby formulas produced in Australia and the U.S. as compared to that produced in China. They are willing to pay more for organic baby formula and baby formula with an excellent reputation. The WTP results from the hardcopy survey indicate that parents are willing to pay more for domestic baby formula. They are also willing to pay more for organic baby formula and baby formula with an excellent reputation. China's emerging demand for imported baby formula, milk powder, and whey may bring more opportunities for the U.S. dairy industry, but U.S. dairy products are also facing increasing competition from similar products from other nations in the Chinese market. More studies are needed to identify the comparative advantages of U.S. baby formula and other dairy products in the Chinese market and to develop effective trade policies for enhancing U.S. exports to China.

The advanced glycation endproducts (AGEs) constitute a large variety of compounds formed from nonenzymatic amino-carbonyl interactions between reducing sugars or oxidized lipids and proteins, nucleic acids or aminophospholipids. The AGEs formation in foods and biological systems is a topic of increasing interest for the science, since they are involved in proinflammatory and pro-oxidative effects related to the pathogenesis of chronic degenerative diseases such as diabetes, Alzheimer's disease and renal failure. The Nε-carboxymethyllisine (CML) was the first AGE identified in foods and, since then, has been the compound of choice in studies on which a single product is used as an AGE marker. Immunochemical or instrumental methods are available for the AGEs determination, but they present limitations and there is not an ideal method yet. Thus, in order to compare and optimize different analytical methods, this study aimed to determine the CML content on enteral and parenteral nutrition formulas by ELISA and LC-MS/MS. So, in order to compare and optimize different analytical methods, this study aimed to determine the content of CML in nutritional enteral and parenteral formulas by ELISA and by liquid chromatography coupled to tandem mass spectrometry (LC-MS / MS). Thus, 5 parenteral and 17 enteral commercially available formulations were investigated. All samples studied showed detectable levels of CML, regardless of the method of analysis used. The parenteral formulations presented CML contents measured by ELISA ranging from 529.9 ± 33.47 to 1948.88 ± 3.68 ng CML/mL of sample and showed positive linear correlations to their content in lipids (0.9259) and carbohydrates (0.9426), but they were not submitted to the LC-MS/MS analysis due to the impossibility of applying the established purification protocol for this group of samples. Enteral formulations analyzed by ELISA presented CML contents ranging from 1076.91 ± 76.87 to 55950.71 ± 1891.29 ng CML/mL of sample and showed positive correlations to its contents in carbohydrate (0.6057), lipid (0.5264) and protein (0.6157). They showed a variation from 0.09 to 0.503 μg CML/mg of protein of the diets when analyzed by LC-MS/MS and there was no correlation between CML and the variables "lipid", "carbohydrate" or "protein" calculated for this group. The investigation conducted during the samples preparation prior to injection into the LC-MS/MS showed a significant loss of CML during the different stages of the protocol, compromising the reliability of the results obtained through this method of analysis, while the comparison between the results obtained through different methods applied to similar samples showed the reliability of the anti-CML ELISA test used in this experiments. The results of this study indicate the need for improvement of AGEs analysis protocols in food and should guide future research on this area. The determination of reliable methods of detection, which enable the measurement of AGEs structures in body fluids, tissues and also in food, in a sensitive, specific, fast and not too expensive way is a challenge that remains present on this field.

Os produtos da glicação avançada (AGEs, do inglês Advanced Glycation Endproducts) constituem grande variedade de substâncias formadas a partir de interações amino-carbonilo, de natureza não-enzimática, entre açúcares redutores ou lipídeos oxidados e proteínas, aminofosfolipídeos ou ácidos nucléicos. A formação de AGEs nos alimentos e em sistemas biológicos constitui tema de crescente interesse, desde que estão associados a efeitos pró-oxidativos e pró-inflamatórios envolvidos na patogênese de diversas doenças crônico-degenerativas como o diabetes, o mal de Alzheimer, a insuficiência renal. A Nε-carboximetilisina (CML) foi o primeiro AGE a ser identificado em alimentos e tem sido o composto de escolha em estudos em que um único produto é usado como marcador de AGEs de um sistema. Métodos imunoquímicos ou instrumentais estão disponíveis para a determinação da CML, mas ambos apresentam limitações, não havendo ainda um método considerado ideal. Assim, a fim de comparar e otimizar diferentes métodos analíticos, o presente estudo teve como objetivo determinar o conteúdo em CML de fórmulas nutricionais enterais e parenterais através das técnicas de ELISA e de cromatografia líquida acoplada à espectrometria de massa tandem (LC-MS/MS). Para tanto, foram investigadas 5 formulações parenterais e 17 enterais comercialmente disponíveis. Todas as amostras investigadas apresentaram níveis detectáveis de CML neste estudo, independentemente do método de análise utilizado. As fórmulas parenterais apresentaram conteúdos mensurados através de ELISA que variaram de 529,9 ± 33,47 a 1948,88 ± 3,68 ng de CML/mL de amostra e apresentaram correlações lineares positivas quanto aos seus conteúdos em lipídeos (0,9259) e em carboidratos (0,9426), mas não foram submetidas às análises através do LC-MS/MS devido à inviabilidade da aplicação para esse grupo de amostras do protocolo de purificação estabelecido nesta investigação. As formulações enterais apresentaram conteúdos em CML que variaram entre 1076,91 ± 76,87 e 55950,71 ± 1891,29 ng de CML/ mL de amostra e evidenciaram correlações positivas quanto aos seus conteúdos em carboidratos (0,6057), lipídeos (0,5264) e proteínas (0,6157), quando analisadas através de ELISA, e apresentaram uma variação de 0,09 e 0,503 μg CML/ mg de proteína das dietas quando analisadas através do LC-MS/MS, não havendo correlações entre a CML e as variáveis “lipídeos”, “carboidratos” ou “proteínas” para esse grupo. A investigação conduzida durante o processo de preparo das amostras, anterior à injeção no LC-MS/MS, evidenciou uma expressiva perda da CML durante as diferentes etapas do protocolo, comprometendo a confiabilidade dos resultados obtidos através desse método de análise, enquanto a comparação entre os resultados encontrados através dos diferentes métodos aplicados a amostras semelhantes em composição e preparo demonstrou a confiabilidade do teste de ELISA anti-CML utilizado nas condições deste experimento Os resultados do presente estudo apontam a necessidade de aperfeiçoamento dos protocolos de análise de AGEs em alimentos e deverão guiar futuras investigações nesta área. Dentre os desafios que permanecem presentes no campo de estudo dos AGEs está a definição de métodos de detecção confiáveis, que possibilitem a mensuração de estruturas nos fluidos ou tecidos corporais e nos alimentos, de maneira sensível, específica, rápida e não muito dispendiosa.

A partir d'un vaste corpus de sources imprimées et manuscrites, cette thèse entend d'abord définir ce que sont les cosmétiques de la période moderne: destinés au visage ou aux cheveux, ces fards, ces poudres et ces pommades sont décrits sur le plan de leur matérialité sensible dans le cadre d'un temps long (XVIe-XVIIIe), puis dans celui de la seconde moitié du XVIIIe siècle, période qui permet de lire des changements significatifs dans leur confection et dans leurs usages. Les cadres intellectuels et techniques qui permettent leur conception et leur fabrication, depuis les affinités avec les pratiques culinaires jusqu' aux frontières de la médecine, et les savoir-faire artisanaux que leur production nécessite et transforme peu à peu sont l'objet d'une seconde partie. La troisième est consacrée à l'analyse de leur consommation, à celle de leur diffusion sociale de plus en plus large et à l' élaboration dans le Paris de la seconde moitié des Lumières d'un véritable marché des cosmétiques.

Cette thèse comporte deux parties. Tout d'abord nous étudions la fonction de Hardy Z(t,\chi) liée à la série L(s,\chi) de Dirichlet. Cette fonction réelle a les mêmes zéros que la fonction L sur la droite critique. Nous regardons ici sa primitive F(T,\chi)=\int_{0}^{T} Z(t,\chi) dt. Dans le cas de la fonction zêta de Riemann, Ivic (2004) a montré la majoration F(T)=O(T^{\frac{1}{4}+\epsilon} et conjecturé que F(T)=\Omega_{\pm} T^{\frac{1}{4}. Cette dernière conjecture a été démontrée par Korolëv (2007) et d'une façon plus précise par Jutila (2011). Ces deux auteurs exhibent aussi un comportement surprenant de F(T). Jutila montre une formule de type Atkinson pour F(T) et en déduit les résultats de Korolëv. La preuve de Jutila demande des adaptations importantes mais nous parvenons à étendre ces résultats à une grande classe de fonctions L de Dirichlet. Nous montrons également que le comportement de F(T,\chi) dépend notamment de la parité de \chi et de celle du conducteur. Les modèles asymptotiques posent de nombreuses questions arithmétiques. Dans la seconde partie, nous étudions certaines fonctions sommatoires des nombres premiers en vue d'estimations explicites dans la lignée de Rosser et Shoenfeld (1962). Nous donnons des estimations explicites pour les sommes de Mertens \sum_{p\leq x} 1/p, \sum_{p\leq x} \log p/p, \sum_{n\leq x} \Lambda(n)/n et les produits eulériens \prod_{p\leq x} (1+z/p); des estimations explicites très précises sont données au moyen d'une région sans zéros pour la fonction zêta de Riemann. La méthode utilisée est celle suggérée par un récent article de Ramaré (Acta Arith., 2014)
This thesis consists of two parts. First of all, we study the Hardy function Z(t,\chi) associated to the Dirichlet L-function L(s,\chi). This real-valued function has the same zeros as L(s,\chi) on the critical line. We look at its primitive F(T,\chi)=\int_{0}^{T} Z(t,\chi) dt. In the case of the Riemann zeta function, Ivic (2004) showed the bound F(T)=O(T^{\frac{1}{4}+\epsilon} and conjectured that F(T)=\Omega_{\pm} T^{\frac{1}{4}. This last conjecture was proved by Korolëv (2007) and in a more precise way by Jutila (2011). These two authors also proved a surprising behaviour of F(T). Jutila proves an Atkinson-like formula for F(T) and deduces the results of Korolëv. Jutila's proof requires significant adaptations but we succeed to extend these results to a large class of Dirichlet L-functions. We also show that the behaviour of F(T,\chi) depends notably on the parity of \chi and of the conductor. The asymptotic models pose many arithmetical questions. In the second part, we study some summatory functions of primes in view of explicit estimates in the line of Rosser and Shoenfeld (1962). We give explicit estimates for the Mertens sums \sum_{p\leq x} 1/p, \sum_{p\leq x} \log p/p, \sum_{n\leq x} \Lambda(n)/n and the Euler products \prod_{p\leq x} (1+z/p); very precise explicit estimates are given by means of a zero-free region for the Riemann zeta function. The method used is suggested by a recent article of Ramaré (Acta Arith., 2014)

One of the main polluting industries in the world with high environmental impact is the construction industry which also generates a huge amount of waste. To overcome the seburdens, we need to reduce the impacts through new solutions, technologies and by injecting circular economy concept into the industry. Construction and building material industry are responsible for nearly 11% of all GHG emissions and the usage of residential/commercial buildings is contributing to 28% of all GHG emissions globally. the construction industry is also responsible for 35% of the total wastes in the European Union. Both linear economy and emissions of the construction sector are becoming more important in recent years that led to the development of many standards, frameworks and innovations. Reporting environmental burdens of the construction elements, products and construction works or construction projects is one of the ways for emissions accounting. Therefore, a report on environmental impacts of goods or services is called environmental product claims which can be based on a single criterion (like CO2 emission or % of recycled content) or based on a complete LCA study with multiple impacts. These reports have been classified by ISO 14020 series in three types, Type I (third-party certified label), Type II (self-declared claims) and Type III (the third party verified declaration based on LCA study). The third type is known as Environmental Product Declaration (EPD). To make the LCA results in EPD:s comparable, Product Category Rules (PCR) are developed. The regulations for the construction materials are defined in EN 15804 so the declarations of the building materials and construction works according to these regulations are compliant with EN 15804. Another framework for environmental declarations called, Product Environmental Footprint (PEF) is developed in Europe. Besides Business to Business declarations that are the target group for EN 15804, PEF also includes environmental labelling (type I) with consumers as the target group. The PCR:s from the updated version of EN15804:2012+A2:2019 can be regarded as the parallel methodology specification for the construction materials in the PEF system. Other product groups' rules and specifications are based on the PEF guidance document. The overall aims of this study are to compare the EN 15804 and PEF formulas concentrating on credits at the end of life and after the end of life stage and to reduce the subjectivity of two variables, energy margin, and recycling rate in the assessment of recycling alternatives after the end-of-life stage. Calculated credits can be included differently in the environmental declarations depending on the methodological approach. PEF includes the End-of-Life (EoL) credits into the Life Cycle Assessment (LCA) study and adds them to the product's performance results, while EN 15804 mandates to report the credits from recycling/recovery separately as supplementary information to the products environmental performance. To compare the credits that are calculated according to PEF and EN 15804, a separate indicator is virtually defined for PEF in order to calculate all the credits separately and compare the results with EN 15804 Module Dresults to give the reader an overview of the most beneficial uses of the construction waste according to PEF and EN 15804. Reducing subjectivity of choosing recycling rate has been addressed by developing more transparent and less subjective tool by integrating and using DGNB (German Sustainable Building Council) and BRE (center for building research in the UK) methods. For energy margin, this has been done by integrating energy margin calculation tool by CDM (Clean Development Mechanism, United Nations) and find the contribution of different materials to the environmental benefits in and after the end of life stage of the building lifecycle. However, the DGNB and BRE methods require further development, since they are not originally developed for LCA studies and just used as the only current options available in order to make recyclability assessment methods compatible with LCA studies. Other methods, specifically for LCA, can also be developed in the future. Based on an inventory of the components and materials used in a real building, the most environmental benefits (credits) from downstream recycling/recovery considering all materials are generated for the wooden products when using the EN 15804 formula, while aluminium is in the second place. On the other hand, aluminium is in the first place and wood is second using the PEF formula. Aluminium has by far the most benefits (credits) considering the credits per kg of each material, due to the huge recycling potential that aluminium has and will replace primary aluminium in the future. Unlike PEF, EN 15804 reports all credits separately outside of the LCA system boundary. This is very beneficial since the correct verified LCA will not beaffected by the credits that are given based on current technologies when the end of life of the building components are between 40 to 120 years away from today.
En av de industrier i världen med högst miljöpåverkan är byggbranschen som också genererar en enorm mängd avfall. För att hantera detta måste vi minska effekterna genom nya lösningar, teknologier och genom att använda konceptet cirkulär ekonomi i byggbranschen. Bygg- och byggnadsmaterialindustrin är ansvarig för nästan 11% av alla växthusgasutsläpp och användningen av bostäder / kommersiella byggnader bidrar till 28% av allaväxthusgasutsläpp globalt. Byggbranschen ansvarar också för 35% av det totala avfallet i EU. Både linjär ekonomi och utsläpp från byggsektorn har blivit viktigare under de senaste åren vilket har lett till utveckling av många standarder, ramverk och innovationer. Att rapportera miljöbelastningar för byggelement, produkter och bygg- och anläggningsarbeten är ett av sätten för utsläppsredovisning. Därför kallas en rapport om miljöpåverkan av varor eller tjänster Miljömärkning som kan baseras på ett enda kriterium (som CO2-utsläpp eller procent av återvunnet innehåll) eller baserat på en fullständig LCAstudie med flera effekter. Dessa rapporter har klassificerats enligt ISO 14020-serien i tre typer, typ I (tredjepartscertifierad märkning), typ II (självdeklarerade påståenden) och typ III (tredjepart verifierad deklaration baserad på LCA-studie). Den tredje typen är känd som Miljövarudeklaration/Environmental Product Declaration (EPD). För att göra LCA-resultat i EPD:er jämförbara, utvecklas Product Category Rules (PCR) (Produktkategoriregler). Regler för byggnadsmaterialen definieras i EN 15804, så deklarationerna om byggnadsmaterial och byggnadsarbeten enligt dessa regler överensstämmer med EN 15804. Ett annat ramverk för miljödeklaration är ProductEnvironmental Footprint (PEF) som är utvecklad inom EU. Förutom Business to Businessdeklarationer som är målgruppen för EN 15804 inkluderar PEF också miljömärkning (typ I) med konsumenter som målgrupp. PCR:erna från den uppdaterade versionen av EN 15804:2012 + A2: 2019 kan betraktas som den parallella metodspecifikationen för byggmaterialen i PEF-systemet. Andra produktgruppers regler och specifikationer är baserade på PEFs vägledningsdokument. De övergripande syftena med denna studie är att jämföra formlerna EN 15804 och PEF som koncentrerar sig på krediter i slutet av livscykeln och att minska subjektiviteten för två variabler, energimarginal och återvinningsgrad vid bedömningen av återvinningsalternativ i slutet av livscykeln. Beräknade krediter kan inkluderas olika i miljödeklarationerna beroende på den valda metoden. PEF inkluderar slutet av livscykeln (EoL)-krediter i livscykelanalys (LCA) -studien och lägger dem till produktens resultat, medan EN 15804 kräver att krediterna från återvinning rapporteras separat som kompletterande information till produkternas miljöprestanda. För att jämföra krediter som beräknas enligt PEF och EN 15804, definieras en virtuell separat indikator för PEF för att beräkna alla krediter separat och jämföra resultaten med EN 15804 Modul D-resultat för att ge läsaren en översikt över de mest fördelaktiga användning av byggavfall enligt PEF och EN 15804. Olika sätt att minska subjektiviteten i valet av återvinningsgrad behandlas genom att utveckla mer transparenta och mindre subjektiva verktyg med hjälp av metoder från DGNB (German Sustainable Building Council) och BRE (Center for building research, UK). Energimarginal behandlas genom att integrera ett verktyg för energimarginaler från CDM (Clean Development Mechanism, FN) och hitta bidraget från olika material till miljöfördelarna i och efter livscykeln för byggnaden. DGNB och BRE metoderna kräver emellertid ytterligare utveckling, eftersom de inte ursprungligen är utvecklade för LCA-studier och bara används som de enda tillgängliga alternativen för att göra utvärderingsmetoder för återvinningsbarhet kompatibla med LCA-studier. Andra metoder, speciellt för LCA, kan också utvecklas i framtiden. Baserat på en inventering av komponenter och material som används i en riktig byggnad, genereras de största miljömässiga fördelarna (krediter) av nedströms återvinning av träprodukter när man använder EN 15804-formeln, medan aluminium ligger på andra plats. Å andra sidan är kommer aluminium i första hand och trä kommer på andra plats med PEFformeln. Aluminium har överlägset flest fördelar (krediter) per kg av varje material, på grundav den enorma återvinningspotentialen som aluminium har och kommer att ersätta primärt aluminium i framtiden. Till skillnad från PEF rapporterar EN 15804 alla krediter separat utanför LCA-systemgränsen. Detta är mycket fördelaktigt eftersom den korrekta verifierade LCAn inte kommer att påverkas av de krediter som ges baserat på nuvarande teknik när byggnadskomponenternas livslängd är mellan 40 och 120 år från idag.

In the context of the world's increasing environmental challenges and the rise of green consumerism, promoting sustainable consumer behavior is more important than ever. This study aims at extending the understanding of consumers' purchase intention of environmentally friendly cosmetic products. With a theoretical starting point in theories of green promotion and the theory of planned behavior, a total of ten hypotheses and sub-hypotheses were formulated to answer the research question how green promotional cues can be used to affect consumers' beliefs and increase purchase intention. Central concepts in the study’s constructed conceptual framework are intrinsic cues which represent concrete characteristics of a product such as ingredients and formula, and extrinsic cues which are attributes not present within the product itself such as packaging and brand. A quantitative approach using an online survey in an experimental vignette designed questionnaire generated responses from a sample of 325 participants in three treatment groups, and the data was subsequently examined through statistical analysis. The study’s main findings show that intrinsic cues have a stronger influence on purchase intention than extrinsic cues but that extrinsic cues seem to have a stronger influence on consumers’ subjective beliefs. The study provides implications on how cosmetic companies can use the insights generated by the study when developing promotional strategies for green cosmetics.

This thesis provides the explicit expression of the star-exponential for the action of normal j-groups on their coadjoint orbits, and of the so-called modified star-exponential defined by Gayral et al. Using this modified star-exponential as the kernel of a functional transform between the group and its coadjoint orbits yields an adapted Fourier transform which is also detailed here. The normal j-groups arise in the work of Pytatetskii-Shapiro, who established the one-to-one correspondence with homogeneous bounded domains of the complex space; these groups are also the central element of the deformation formula recently developed by Bieliavsky & Gayral (a non abelian analog of the strict deformation quantization theory of Rieffel). Since these groups are exponential, the results given in this text illustrate the general work of Arnal & Cortet on the star-representations of exponential groups.

As this work is meant to be as self-contained as possible, the first chapter reproduces many definitions introduced by Bieliavsky & Gayral, in order to obtain the expression of the symplectic symmetric space structure on normal j-groups, and of their unitary irreducible representations. The Weyl-type quantizer associated to this symmetric structure is then computed, thus yielding the Weyl quantization map for which the composition of symbols is precisely the deformed product defined by Bieliavsky-Gayral on normal j-groups. A detailed proof of the structure theorem of normal j-groups is also provided.

The second chapter focuses on the expression and properties of the star-exponential itself, and exhibits a useful tool for the computation, namely the resolution of the identity associated to square integrable unitary irreducible representations of the groups. The result thus obtained satisfies the usual integro-differential equation defining the star-exponential. A criterion for the existence of a tempered pair underlying a given tempered structure on Lie groups is proven; the star-exponential functions are also shown to belong to the multiplier algebra of the Schwartz space associated to the tempered structure. Before that, it is shown that all Schwartz spaces that appear in this work are isomorphic as topological vector spaces.

The modified version of this star-exponential is computed in chapter three, first for elementary normal j-groups and then for normal j-groups. It is then used to define an adapted Fourier transform between the group and the dual of its Lie algebra. This transform generalizes (to all normal j-groups) a Fourier transform that was already studied in the “ax+b” case by Gayral et al. (2008), as well as by Ali et al. (2003) in the context of wavelet transforms.

The classical Euler decomposition expresses a product of two Riemann zeta values as double Euler sums and it leads to a weighted sum formula among double Euler sums. Through a particular integral representation of Riemann's zeta values, we are able to carry out the shuffle product of $n$ Riemann zeta values. As results, we produce some weighted sum formulas among multiple zeta values of depth 2, 3 and 4. In particular when the depth $n=4$, the weighted sum formula is given by \begin{align*} &\sum_{|\balpha|=k+7}\zeta(\alpha _{1},\alpha_2,\alpha_3,\alpha _{4}+1)\left \{ 2^{\alpha _{2}-1}3^{\alpha _{3}-1}\left ( 4^{\alpha _{4}}-3^{\alpha _{4}} \right ) \right.\\ &\qquad \quad\quad\quad\quad \left. -\left ( 2^{\alpha _{2}+\alpha _{3}-2}+2^{\alpha _{3}-1} \right ) \left ( 3^{\alpha _{4}}-2^{\alpha _{4}} \right )+\left (2^{\alpha _{4}} -1\right )\right \}\\ &-\sum_{|\balpha|=k+6}\zeta(1,\alpha_2,\alpha_3,\alpha _{4}+1)\left \{ 2^{\alpha _{3}-1}\left ( 3^{\alpha _{4}}-2^{\alpha _{4}} \right )-\left (2^{\alpha _{4}} -1\right )\right \}\\ & +\sum_{|\balpha|=k+5}\zeta(1,1,\alpha_3,\alpha_4+1)\left \{ 2^{\alpha _{4}}-1 \right \}-\zeta \left ( 1,1,1,k+5 \right)\\ & =\frac{1}{24}\sum_{\left | \mathbf{a} \right |=k}\zeta(a_{1}+2)\zeta(a_{2}+2)\zeta(a_{3}+2)\zeta(a_{4}+2).

In the early years, engineers designed logical circuits with hand drawing which is very inefficient and costly. Now, circuit design using high-level hardware description languages is a new trend. High-level hardware description languages can be used to describe, synthesize, and simulate hardware circuits. With the standard of hardware description language developed up in recent years, we will use mathematical formulas to describe computational problems, then to synthesize hardware description language programs from mathematical formulas. The synthesizing results may be efficiently used in hardware circuit design, and optimizing circuits. In this thesis, we present a system to translate tensor product formulas to VHSIC Hardware Description Language (VHDL) programs. Tensor product formulas are used to represent block recursive algorithms. Operations of tensor product formulas can be mapped to programming language constructs. We use VHDL as our target programming language for program synthesis. VHDL contains high-level programming language constructs as well as low-level constructs for describing hardware components. Hence, VHDL is suitable for VLSI circuit design. In our system, a tensor product formula is written in a LISP-like form and translated into VHDL code containing bit-level objects and operations. We use the parallel prefix problem as an example to illustrate program synthesis.

For a multi-index $\mfa = (\seq{a}{1}{2}{p})$ of positive integers with $a_{p} \geq 2$, a multiple zeta value of depth $p$ and weight $\av{\mfa} = \fsum{a}{1}{2}{p}$ or $p$-fold Euler sum is defined to be \[ \zeta(\seq{a}{1}{2}{p}) = \sum_{1 \leq n_{1} < n_{2} < \cdots < n_{p}} n_{1}^{-a_{1}} n_{2}^{-a_{2}} \cdots n_{p}^{-a_{p}}, \] which is a natural generalization of the classical Euler sum \[ S_{a, b} = \sum_{k=1}^{\infty} \frac{1}{k^{b}} \sum_{j=1}^{k} \frac{1}{j^{a}}, \quad a, b \in \bn, \quad b \geq 2. \] Multiple zeta values can be expressed as Drinfel'd iterated integrals over a simplex of weight dimension and the shuffle product of two multiple zeta values can be defined. In this dissertation I shall provide a number of algebraic relations among multiple zeta values using a modified shuffle product formula to certain integrals. Furthermore, the shuffle product of two multiple zeta values of weight $m$ and $n$, respectively, will produce $\binom{m+n}{m}$ multiple zeta values of weight $m+n$. By counting the number of multiple zeta values in relations produced from the shuffle product of two particular multiple zeta values, we obtain many specific combinatorial identities such as \[ \binom{m+n+4}{i+j+2} = \sum_{m_{1}+m_{2}=m} \brac{\binom{m_{1}}{i} \binom{m_{2}+n+3}{j+1} + \binom{m_{1}}{m-i} \binom{m_{2}+n+3}{n-j+1}} \] and \begin{align*} \binom{i+j}{i} \binom{m+n+4}{i+j+2} &= \binom{i+j}{i} \brac{\binom{m+j+3}{i+j+2} + \binom{i+n+2}{i+j+2}} \\ &\quad + \sum_{m_{1}+m_{2}=m} \sum_{n_{1}+n_{2}=n} \binom{n_{1}+i-m_{2}}{n_{1}} \binom{n_{1}+m_{1}+2}{m-i+1} \binom{m_{2}+j-n_{1}}{m_{2}} \binom{m_{2}+n_{2}+1}{n-j}, \end{align*} where $(m, n, i, j)$ is a quadruple of nonnegative integers with $i \leq m$ and $j \leq n$.

We study central derivatives of L-functions of cuspidal automorphic representations for unitary groups of even variables defined over a totally real number field, and their relation with the canonical height of special cycles on Shimura varieties attached to unitary groups of the same size. We formulate a precise conjecture about an arithmetic analogue of the classical Rallis' inner product formula, which we call arithmetic inner product formula, and confirm it for unitary groups of two variables. In particular, we calculate the Néron-Tate height of special points on Shimura curves attached to certain unitary groups of two variables. For an irreducible cuspidal automorphic representation of a quasi-split unitary group, we can associate it an ε-factor, which is either 1 or -1, via the dichotomy phenomenon of local theta liftings. If such factor is -1, the central L-value of the representation always vanishes and the Rallis' inner product formula is not interesting. Therefore, we are motivated to consider its central derivative, and propose the arithmetic inner product formula. In the course of such formulation, we prove a modularity theorem of the generating series on the level of Chow groups. We also show the cohomological triviality of the arithmetic theta lifting, which is a necessary step to consider the canonical height. As evidence, we also prove an arithmetic local Siegel-Weil formula at archimedean places for unitary groups of arbitrary sizes, which contributes as a part of the local comparison of the conjectural arithmetic inner product formula.

This thesis consists of two topics. First we study F-virtual Abelian varieties of GL2-type where F is a number field. We show the relation between these Abelian varieties and those defined over F. We compare their l-adic representations and study the modularity of F-virtual Abelian varieties of GL2-type. Then we construct their moduli spaces and in the case where the moduli space is a surface we give criteria when it is of general type. We also give two examples of surfaces that are rational and one that is neither rational nor of general type. Second we prove a crucial case of Siegel-Weil formula for orthogonal groups and metaplectic groups. With this we can compute the pairing of theta functions and show in this case that it is related to the central value of Langlands L-function. This new case of Rallis inner product formula enables us to relate nonvanishing of L-value to the nonvanishing of theta lifting.

We present explicit central value formulae for certain triple product L-functions over a totally real number field by using Ichino''s formula. In particular, we carry out explicit computations for the local period integrals at the real defined in the Ichino''s formula in very general settings. As applications, we first establish the rationality of the central critical values of these triple product L-functions. Base on this result, we prove the Deligne''s conjecture for the central critical values of certain class of automorphic L-functions for GL(2)xGL(3).

Hyperlipidemia is regarded as the main risk factor of cardiovascular disease (CVD) and atherosclerosis. Previous study suggested that the increase of dietary fiber intake could be additive for blood lipid-lowering. For this reason, there are many blood lipid-regulating products available in market. The present study was to investigate the effect of resistant maltodextrin formula product on blood lipid-regulating in hamster model. Hamsters were fed by high-fat diet containing 15% fat (5% soybean oil, 10% butter) and 0.2% cholesterol to induce hyperlipidemia, then given the dietary fiber product at different dosages for 8 weeks. Our results showed that compared with HF group, medium and high dose groups could significantly (p < 0.05) decreased serum triglyceride (14.4-15.9%), serum total cholesterol (13.5-22.7%), HDL-C (10.7-16.6%) and LDL-C (19.4-48.7%). Furthermore, HDL / TC ratios were slightly elevated in the medium and high dose groups, however, significant (p < 0.05) decreases in LDL / TC and LDL / TC ratios were observed . On liver lipids and fecal moisture content, there was no obvious effect on liver cholesterol concentration. However, compared with HF group, liver triglycerides were significantly (p < 0.05) decreased by 16-31% in medium and high dose groups. Meanwhile, fecal moistures content were significantly (p < 0.05) increased by 10-13%. With the liver lipids being reduced, the liver weights were slightly decreased. Overall, it was confirmed that the resistant maltodextrin formula product could moderate blood lipid and had dosage effect. In addition, it also had an ability to lower liver lipids and increase fecal water content. These findings could be useful for confirming the effective dosage of the resistant maltodextrin formula product.

Atherosclerosis and cardiovascular disease are common health problems in the world, especially in developed countries. diseases, hyperlipidemia is regarded as the major risk factor. In these Previous researches suggested that increasing dietary fiber intake could improve hyperlipidemia, and many high-fiber products are available in the market. Soy protein and oligosaccharide have been shown to have promising lipid-lowering effects in many studies. U.S. Food and Drug Administration has claimed that intake of 25 g of soy protein daily may reduce risk factors of cardiovascular disease. In this study, a soy protein oligosaccharide formula which was developed by using soy protein and oligosaccharide was examined for its lipid-lowering ability, by using a hamster model. Hamsters were divided into five groups; they were fed with different high fat diets (with 14% fat, 0.2% cholesterol) and soy protein oligosaccharide formula with different dosages for 8 weeks. Our results showed that the middle-dose group (1X) and high-dose group (2X), compared to the high fat control group (HF), apparently (p < 0.05) decreased serum total cholesterol (20%), high-density lipoprotein cholesterol (12-14%) and low-density lipoprotein cholesterol (30-40%) concentrations. In addition, a significant (p < 0.05) decrease in LDL-C/TC and LDL-C / HDL-C ratio was observed in high-dose group. The results showed that the oligosaccharide portion of the sample was the major component that regulated blood lipids. The liver total cholesterol were significantly (p < 0.05) reduced by 12% in the high-dose group, as compared to the high-fat control group. The moisture in feces is significantly (p < 0.05) increased by 5-12% in the high-dose group. In conclusion, this study suggested that consumption of the soy protein-oligosaccharide formula had a positive effect on regulating blood lipids in middle-dose and high-dose groups, which resulted in the effective reduction in liver cholesterol and increase in fecal moisture content.

The purpose of this study was to investigate the effects of isolated soy protein (ISP) formula product on improvement of exercise capacity through different exercise models in mice. This study was based on the protein RDA of athletes, which is 1.6 g/kg body weight. In other words, the daily supplementation of protein to athletes is double the normal dietary protein intake of 0.8 g/kg body weight. Different exercise models, including swimming, running using rota-rod and treadmill (end point and fixed time) apparatus, and hanging on a horizontal bar, were selected to assess sports performance of control and sample groups. The result of this study showed that blood glucose of sample group was higher than control group, while blood lactate of sample group was lower than control group in short swimming duration (0-5 minutes) and short treadmill running duration (0-10 minutes). The experimental outcome suggested that daily supplementation of ISP formula product by consuming 0.8 g/kg body weight improves exercise capacity.
