A l'occasion de cette étude, à la suite des travaux d'Anne-Marie Lecoq (1987), nous sommes revenus sur le discours héraldique de la comtesse et duchesse d'Angoulême, Louise de Savoie, l'influente mère de François Ier. Nous avons présenté et explicité ses devises favorites, à savoir la cordelière, qui évoque autant le nœud de Savoie que la cordelière franciscaine, le vol, sans doute choisi puisque l’aile évoque le L de Louise par homophonie, le bouquet de lis ou le cygne « navré », mais aussi les écus et les monogrammes qui lui sont associés et qui ponctuent enluminures, tapisseries, bas-reliefs et éléments sculptés de l’architecture. Notre intention a été de montrer d’une part comment Louise de Savoie manifeste, par l’intermédiaire de ces signes emblématiques, son identité et son pouvoir, d’autre part comment elle construit, par leur biais, un patrimoine, mental, susceptible de renforcer son clan et ses héritiers.

Comtesse puis duchesse d’Angoulême, Louise de Savoie (1476-1531) est l’une des personnalités les plus influentes de la première Modernité européenne. Elle n’est pas seulement la mère de deux enfants illustres, Marguerite, future reine de Navarre, et François, futur François Ier, elle est aussi la sœur de Philibert II le Beau, duc de Savoie. Une fois son fils monté sur le trône de France, Louise domine le Conseil et assure, à deux reprises, la régence du royaume. Son action concerne encore les arts et les lettres : amatrice d’objets d’art et bibliophile avertie, elle demande à Léonard de Vinci d’imaginer une ville et un palais neuf à Romorantin, participant de la sorte à la diffusion en France des idées et des formes venues d’Italie. Curieusement, alors que son influence fut considérable, Louise de Savoie n’a pas fait l’objet d’une monographie récente (un ouvrage collectif à son propos paraîtra toutefois en 2015). Son emblématique n’a plus été analysé depuis les travaux d’Anne-Marie Lecocq (1987), qui s’était essentiellement concentrée sur les signes présents dans les livres qu’elle commanda pour soutenir l’éducation de ses enfants. À l’occasion de cette communication – prolongeant ainsi une recherche entreprise avec Pierre-Gilles Girault – nous voudrions revenir sur le discours héraldique de Louise de Savoie, en explicitant l’une de ses devises favorites, la cordelière. Pour la mère de François Ier, la corde à plusieurs nœuds revêt plusieurs significations. D’abord, puisqu’elle se compose de nœuds de Savoie, un emblème largement diffusé au début du XVIe siècle, notamment sous l’influence de Philibert II le Beau et Marguerite d’Autriche, elle souligne l’appartenance de la dame à la maison de Savoie. Ensuite, et ce de façon inédite au sein de la maison de Savoie, la cordelière de Louise associe nœuds de Savoie et cordon franciscain, une référence que nous proposons d’expliquer non pas uniquement, comme on le fait traditionnellement, par les liens prétenduement étroits qui reliaient la mère de François Ier avec l’ordre des Franciscains. Pour Louise, il s’agit sans doute aussi de se situer dans la lignée d’Anne de Bretagne, à laquelle la cordelière est indéniablement liée. [less ▲]

We present in this paper a new generic approach to variable branching in branch-and-bound for mixed- integer linear problems. Our approach consists in imitating the decisions taken by a good branching strategy, namely strong branching, with a fast approximation. This approximated function is created by a machine learning technique from a set of observed branching decisions taken by strong branching. The philosophy of the approach is similar to reliability branching. However, our approach can catch more complex aspects of observed previous branchings in order to take a branching decision. The experiments performed on randomly generated and MIPLIB problems show promising results. [less ▲]

The organocatalytic coupling of CO2 with oxetanes is investigated under solvent-free conditions. The influence of the main reaction parameters (type of organocatalytic system, pressure and temperature) on the yield, the product formed and the selectivity of the reaction are discussed. An onium salt combined with a fluorinated alcohol promotes the efficient and selective organocatalytic synthesis of ?,?-hydroxyl oligocarbonates by coupling CO2 with oxetanes at 130°C and at a CO2 pressure as low as 2 MPa. NMR characterizations were correlated with MALDI-ToF analyses for elucidating the structure of the oligomers. Online FTIR studies under pressure, NMR titrations and DFT calculations allowed an in-depth understanding of the reaction mechanism. Finally, CO2- based poly(carbonate-co-urethane)s were synthesized by step- growth polymerization of hydroxyl telechelic oligocarbonates with MDI. The organocatalytic system described in this paper constitutes an innovative sustainable route to the selective preparation of hydroxyl telechelic carbonates, of high interest for many applications, notably for the polyurethane business, especially for coatings or foams.

A multi-methodological approach was used to study the isothermal crystallization of cocoa butter (CB) in the presence of sunflower oil based cocoa butter equivalents (CBEs). pNMR, DSC, oscillatory rheology, XRD, and PLM were used for this purpose. All the techniques confirmed that at 20°C isothermal crystallization of all the blends is a two-step process with formation of α crystals in the first step and formation of β’ crystals in the second step. The blends with high amount of CBEs contained more high-melting triacylglycerols (TAGs) and diacylglycerol (DAG) in compare with CB acting as seed crystals enhancing the formation of a- crystals in the first crystallization step. Therefore, the induction time of the first crystallization step was inversely related to the amount of CBE. In contrast, the subsequent polymorphic transition was delayed by the presence of the CBE due to their low-melting TAGs. However, adding up to 5% CBE did not change the Foubert’s parameters for isothermal crystallization significantly. All the blends (except 5% HOSO CBE), had a mediated β’ crystallization. Picturing of the microstructure showed that for the CB and the blends up to 50% large microstructures, indicative of the bV polymorph developed during storage. At 100%, a dense network of spherulites was formed at the beginning of the crystallization period, but upon further storage, no large morphological changes were observed. Practical applications: In recent years, the production of CB has been delayed owing to its cultivation difficulty and low yield due to pest attack, while the world cocoa prices have increased with rising demand and higher chocolate consumption. Therefore, there is a need to develop low-priced and appropriate alternatives to CB. Accordingly, in this study two sunflower oil based CBEs were produced with fatty acid mixtures in the presence of immobilized 1,3-regiospecific lipase. The results from this study could help the fats and oils industries to extend their knowledge on the crystallization and polymorphic behavior of two enzymatically produced sunflower oil based CBEs.

Introduction : La procrastination est définie comme une tendance à reporter ce qui est nécessaire pour atteindre un objectif. Ainsi, la procrastination concerne une intention qui ne se traduit pas en action. L’intention d’implémentation se définit notamment à travers le désengagement face au problème, l’orientation vers les buts, et l’activation des ressources et cette étude examine la part explicative de ces trois dimensions dans le processus de procrastination. Méthodologie : Un échantillon de 197 étudiants ont complété les versions françaises du Solution Focused Inventory (SFI), et du Procrastination Assessment Scale for Students (PASS). Résultats : L’intention d’implémentation intervient dans 32% de la variance de la procrastination. Le désengagement face au problème et l’orientation vers les buts expliquent de manière significative la fréquence de procrastination.  Conclusion : Le processus de procrastination pourrait en partie être expliqué par manque d’intentions d’implémentation, plus particulièrement par une difficulté à se désengager du problème (tendance à être bloqué dans sa réflexion en se focalisant davantage sur les problèmes) et à s’orienter vers les buts (présenter des difficultés à mettre au point des plans d’action efficaces).

Production and purification of hydrophobin HFBII has recently been the subject of intensive research, but the yield of production needs to be further improved for a generic use of this molecule at industrial scale. In a first step, the influence of different carbon sources on the growth of Trichoderma reesei and the production of HFBII was investigated. The optimum productivity was obtained by using 40 g/L lactose. Carbon starvation and excretion of extracellular enzyme were determined as two main conditions for the production of HFBII. In the second phase, and according to the physiological mechanisms observed during the screening phase, a bioreactor set up has been designed and two modes of cultures have been investigated, i.e. the classical submerged fermentation and a fungal biofilm reactor. In this last set-up, the broth is continuously recirculated on a metal packing exhibiting a high specific surface. In this case, the fungal biomass was mainly attached to the metal packing, leading to a simplification of downstream processing scheme. More importantly, the HFBII concentration increased up to 48.6 ± 6.2 mg/L which was 1.8 times higher in this reactor configuration and faster than the submerged culture. X-ray tomography analysis shows that the biofilm overgrowth occurs when successive cultures are performed on the same packing. However, this phenomenon has no significant influence on the yield of HFBII, suggesting that this process could be operated in continuous mode. Protein hydrolysis during stationary phase was observed by MALDI-TOF analysis according to the removal of the last amino acid from the structure of HFBII after 48 h from the beginning of fermentation in biofilm reactor. Hopefully this modification does not lead to alternation of the main physicochemical properties of HFBII. [less ▲]

Hydrogels based on polyurethane (PU) are promising (bio-) materials because of their bio- compatibility, biodegradation and excellent mechanical properties. In this publication, polyurethane hydrogels were produced for the first time by a non-isocyanate route by solvent-free step-growth copolymerization between a CO2-sourced hydrophilic polyethy- lene glycol bi-cyclic carbonate with diamines in the presence of a cross-linker. Kinetic of poly(hydroxyurethane) (PHU) synthesis was monitored by ATR-IR and the chemical cross-linking was confirmed by rheology and gel contents measurements. Hydrogels were obtained by immersion of PHUs in water and the influence of the diamine/cross-linker ratio and the nature of diamine on the water swelling and compression properties (compression modulus, strain and stress at break) of PHU hydrogels was evaluated. Additionally, the compression properties of the hydrogels were improved by the addition of Montmorillonite as nanofiller in the PHU formulation. This work opens new application fields for CO2-sourced PHUs. [less ▲]
