Arabinoxylans (AXs) were extracted from destarched wheat bran (DWB) according to different processes, with a view to their production at industrial scale. Two fractions (F3a and F3b, respectively purified on 10 kDa and 100 kDa ultrafiltration membranes) were obtained with low yields by treating DWB with an endoxylanase and this process left a solid residue exhausted in enzyme-extractable AXs (EDWB). F1 and F2 AX fractions were obtained by treatment with sodium hydroxide of respectively DWB and EDWB. The fraction F4 resulted from a hydrothermal treatment of EDWB in a pressure reactor, followed by ethanol precipitation. The different AX fractions were characterized and compared for the composition in monosaccharides, for the contents in fats and in ferulic, phytic and uronic acids, for the molecular mass distribution and the degrees of methylation and acetylation. The alkaline extractions gave one desesterified AX population with molecular mass (MM) higher than 670 kDa and arabinose/xylose ratios (Ara/Xyl) around 1. The enzyme and thermal treatments yielded AXs with two main populations in size-exclusion chromatography (the largest one at 5-12.5 kDa and a second one at 140-160 kDa), having overall Ara/Xyl of respectively 0.7 and 0.5 for both processes. These data bring information about the influence of the process on the characteristics of AX fractions obtained from pretreated wheat bran. Here are also reported processes that enabled to recover enzyme-unextractable AXs from DWB, including an original and up-scalable hydrothermal extraction. Phytate contents of isolated AXs are described for the first time. [less ▲]

Objective: The operatic singing technique is frequently employed in classical music. Several acoustical parameters of this specific technique have been studied but how these parameters combine remains unclear. This study aims to further characterize the Western operatic singing technique by observing the effects of melody and technique on acoustical and musical parameters of the singing voice. Methods: Fifty professional singers performed two contrasting melodies (popular song and romantic melody) with two vocal techniques (with and without operatic singing technique). The common quality parameters (energy distribution, vibrato rate and extent), perturbation parameters (standard deviation of the fundamental frequency, signal-to-noise ratio, jitter and shimmer) and musical features (fundamental frequency of the starting note, average tempo, and sound pressure level) of the 200 sung performances were analyzed. Results: The results regarding the effect of melody and technique on the acoustical and musical parameters show that the choice of melody had a limited impact on the parameters observed, whereas a particular vocal profile appeared depending on the vocal technique employed. Conclusions: This study confirms that vocal technique affects most of the parameters examined. In addition, the observation of quality, perturbation and musical parameters contributes to a better understanding of the Western operatic singing technique. [less ▲]

A horizontal tubular fixed bed bioreactor (HFBR) and an anaerobic biodisc-like reactor (AnBDR) were designed to both fix Clostridium biomass and enable rapid transfer of the hydrogen produced to gas phase in order to decrease the strong effect of H2 partial pressure and H2 supersaturation on the performances of Clostridium strains. The highest H2 production rate (703 mL H2/L.h) and yield (302 mL/g glucose consumed i.e. 2.4 mol/mol) with the pure culture were recorded in the AnBDR with 300 mL culture medium (total volume 2.3 L) at pH 5.2 and a glucose loading rate of 2.87 g/L.h. These results are about 2.3 and 1.3-fold higher than those achieved in the same bioreactor with 500 mL liquid medium and with the same glucose consumption rate. Therefore, our experimentations and a short review of the literature reported in this paper emphasize the relevance of performing bioreactors with high L/G transfer. [less ▲]

La notion de « crise » revêt une acuité particulière pour le droit économique. L’effondrement boursier de 1929, le choc pétrolier de 1978 et les crises bancaires et financières de 2008 et 2011 en constituent des illustrations spectaculaires. Outre le fait qu’une crise affecte la vie quotidienne des hommes et des femmes dans de nombreuses régions du monde, celle-ci génère des réponses juridiques nouvelles, souvent précipitées ou improvisées, de la part des pouvoirs publics et privés. À l’occasion de son trentième anniversaire, l’Association Internationale de Droit Économique a souhaité consacrer une réflexion de fond à ce phénomène. Le symposium organisé à Wroclaw pour célébrer ce jubilé avait ainsi pour ambition de porter un regard critique sur trois domaines en lien avec la thématique générale de la crise : le sort des institutions et de la gouvernance, la confection et l’application des normes et la remise en cause des valeurs sous-jacentes aux systèmes économiques hérités des Trente Glorieuses. L’objet des travaux ainsi réunis consiste dès lors dans une analyse en profondeur des mutations juridiques induites des périodes de crise, qui intéressera dès lors non seulement le praticien soucieux de mesurer le contexte socio économique dans lequel il intervient mais aussi les chercheurs en sciences humaines ouverts à l’interdisciplinarité (droit, économie, gestion, sciences politiques, philosophie).
