Properties of shooks ageing by a treatment in a solution of natural enzymes. A speeding up of the ageing of shooks is possible by a treatment with a solution of natural enzymes. However its repercussion on physical, mechanical characteristics of wood and on its absorption potential of an hydro-alcoholic solution must be tested. Normalized samples have been extracted from 150 shooks selected on a ring width criteria from three cooperages located on different supplying area in France. The three factors cooperage, ring width class and treatment are used for statistical analysis. The cooperage factor, reflection of the supply area of each of them, affect the young modulus and the modulus of rupture in static bending but not the other characteristics. The improvement of the wood properties is closely linked to the ring width increaseof the samples. The enzymatic treatment has no significant effect on physical and mechanical characteristics of oak wood, except on the hardness and, to a lesser extent, on the absorption potential. Considering the absence of negative effect on characteristics of shooks and the positive contribution of enzymatic treatment on their ageing, this treatment could bring a very interesting economical alternative permitting to avoid long lasting storage of the shooks before assembly.

Les diurétiques d'épargne potassique se répartissent en deux groupes: les inhibiteurs compétitifs de l'aldostérone représentés par la spironolactone et ses métabolites canrénone et acide canrénoïque, d'une part, et l'amiloride et le triamtérène d'autre part. Agissant au niveau du tube distal, l'effet de ces diurétiques est caractérisé par un effet natriurétique faible, mais surtout une diminution de l'excrétion urinaire d'ions K+ et H+. De par leur mode d'action, le principal effet secondaire est représenté par le risque d'hyperkaliémie. Certains effets secondaires liés à la structure même de la molécule en limitent l'utilisation chronique tels les effets anti-androgènes de la spironolactone: gynécomastie, impuissance, trou bles des règles, etc. .. En dehors de l'hyperaldost éronisme primaire et secondaire, leur principale indication réside dans le traitement et la prévention de l'hypokaliémie induite par l'utilisation des thiazides, en particulier dans le traitement de l'hypertension artérielle.

Interfacial properties of gluten proteins are important in determining flour breadmaking quality especially the gas bubbles stability in dough, which influences the loaf volume and crumb texture. The interfacial properties of gluten extracted from four commercial flours have been studied. The behaviour of gluten monolayer spread at the air-water interface is influenced by the gliadins/glutenins ratio. Films of gluten extracted from flours with high gliadins/glutenins ratio spread more quickly, present a higher stability (Pi c) and are more resistant under high compression. [less ▲]

The use of in-flight Oxygen Collection has shown to significantly improve space launcher performance. The conceptual approach followed by the Royal Military Academy of Brussels (RMA) has tried to widen the available design margins in order to reduce the required technological leap and limit the economical risk associated with such a development. The aim of the ESA-funded theoretical and experimental study on an air separation device is to demonstrate the possibility of performing efficient air distillation in a compact rotating column. An integration of the vehicle, propulsion system and separation unit designs is presented aiming to optimise the overall vehicle performance while keeping technological difficulty and system complexity at a reasonable level. Reference vehicles are presented in their specific mission profiles with an emphasis on TSTO’s. Different layouts of the internal energy and mass flowsheets have been studied and were compared in order to make best use of the refrigeration capacity of the hydrogen fuel running though the propulsion system during the first phase of the flight considering the separator as a classical distillation column. This analysis provides the requirements in terms of heat exchange capacity, compression ratios and number of so-called transfer units needed in the separator. Here, the system is intentionally kept simple, to limit complexity, but the analysis is thorough and accurate, including, for example, the effect of the presence of argon. Results for a supersonic carrier are presented. An analysis of the separation unit to reach those requirements has been performed. That includes internals, practical building with estimates of pressure drop, separation performance and flow limitation. The sizing of the separator bed is provided for a carrier plane showing that such on-board separator is indeed practical. [less ▲]

Different layouts of the internal energy and mass flowsheets have been studied and were compared in order to make best use of the refrigeration capacity of the hydrogen fuel running through the propulsion system during the first phase of the flight. In those flowsheets, the separator is considered as a classical distillation tray column. That analysis provides the requirements in terms of heat exchange capacity, compression ratios and number of so-called transfer units needed in the separator. The system is intentionally kept simple to limit complexity, but the analysis is thorough and accurate, including, for example, the effect of the presence of argon. Results for a supersonic carrier are presented. A compact separation unit has been designed in order to reach those requirements. That includes internals, practical building with estimates of pressure drops, separation performance and flow limitation. Main results are given, sizing of the separator bed is provided for a carrier plane showing that such on-board separator is indeed practical. (C) 2007 Elsevier Masson SAS. All rights reserved.
