La fabrique politique de la métropole du Grand Paris
Authors: Le Lidec Patrick 
Published: January 2019

Cet article analyse les mécanismes qui influencent l’élaboration des statuts métropolitains. Il mobilise une approche de « process tracing » déductif pour comprendre un cas : la mise en place d’une scène métropolitaine puis la création d’un gouvernement métropolitain du Grand Paris. La forme particulière prise par cette métropole à l’issue des lois de 2014 et 2015 est saisie à l’articulation de quatre mécanismes : la reproduction d’un héritage institutionnel local, caractérisé par la fragmentation et la polarisation ; la mobilisation d’entrepreneurs institutionnels locaux cherchant à manipuler à leur avantage les statuts métropolitains ; l’intervention des membres de l’exécutif politique central, soucieux de la viabilité parlementaire et des bénéfices partisans associés à la mise en place de la métropole ; le rôle de cadrage d’une administration centrale, porteuse d’un projet rationalisation institutionnelle par fusion verticale.
Topoï et légitimation des politiques austéritaires. Une étude des éditoriaux de La Presse de 1980 à 2015
Authors: Dufour Mathieu , Laurin-Lamothe Audrey , Peñafiel Ricardo 
Published: January 2019

Cet article s’intéresse à la diffusion des topoï d’une vulgate néolibérale, à travers une analyse discursive longitudinale, de 1980 à 2015, des éditoriaux de La Presse , l’un des principaux quotidiens québécois. L’analyse thématique, argumentative, pragmatique et énonciative de ce corpus est menée en dialogue avec les théories économiques impliquées dans les énoncés des éditoriaux. Car, bien que les lieux communs ( topoï ) développés ou mobilisés par La Presse simplifient à l’extrême ces théories, les relations entre ces deux niveaux de circulation sont constitutives des règles de dispersion de l’événement discursif austéritaire. Cette étude montre comment la construction d’un topos anti-déficits dans les années 1980 réfute d’emblée (sans besoin d’argumentation) toute politique impliquant des dépenses publiques. Étudiant comment ce topos s’adapte à différents changements de conjoncture en engendrant et en s’articulant à d’autres topoï austéritaires, l’analyse montre les conditions de possibilité d’une austérité permanente, légitimant entre autres une criminalisation de la grève et une normalisation de lois d’exception, décrétant les conditions de travail des salariés.

Malthus is still breathing: Environmental concerns and attitudes towards immigration in Europe
Authors: Puskarova Paula , Dancakova Ivana 
Published: January 2019

Le travail porte sur les préoccupations environnementales des populations européennes face à la crise des réfugiés. À l’aide de l’enquête sociale européenne de 2016, nous estimons les effets des craintes concernant l’environnement tout en contrôlant les facteurs individuels et institutionnels. Les résultats suggèrent que, même si les questions de sécurité expliquent la plus grande part des attitudes vis-à-vis de l’immigration, les préoccupations environnementales dépassent nettement les effets statistiques de la religion, du revenu ou de l’expérience de la vie à l’étranger.

Published: January 2019

An oil from Pacific krill (Euphausia pacifica) has a high content of PUFAs and phospholipids. The sediment was formed with homogenization of krill oil and maltodextrin (MD; dextrose equivalent (DE) = 19) solution using sodium caseinate, gum arabic, hydrolyzed whey protein or modified starch as a surfactant. Quillaja saponin could form the emulsion without the sediment. MD (28.5 wt%) was solubilized with distiller water (50 wt%) and mixed with krill oil (20wt%) and Quillaja saponin (1.5 wt%). The homogenized solution was spray-dried using Okawara-L8 spray dryer with a centrifugal atomizer. Spray-dried powder was evaluated in the oil-droplet size and surface-oil content. Keywords: krill oil, emulsion, Quillaja saponin, spray drying, PUFAs

Published: January 2019

The physical properties of 12 commercially available infant milk formula (IMF) and follow-on (FO) powders were assessed. Polarised light micrographs of powders revealed that two types of powders existed: Type I - homogenous mixtures of milk powder particles and Type II – heterogeneous mixtures of milk powder particles and tomahawk-shaped a-lactose monohydrate crystals. Conventionally employed correlations between particle size, flowability and compressibility were found to be highly dependent on the presence of crystalline lactose in powders. Overall, results showed the importance of micro-structural evaluation during analysis of physical properties of dairy powders and, in particular, IMF/FO powders. Keywords: max.

Published: January 2019

The aim of this work was to determine the microwave drying kinetics of Eucalyptus Gomphocephala wood and to investigate the influence of intermittent and continuous heating processes on the end quality of dreid samples. The average moisture content evolution and temperature of wood samples under different microwave powers were analyzed in terms of drying time and internal temperature level. Results show that the increase of microwave power level decreses the drying time and increases the internal wood temperature. Based on qualitative observations on the state of dried samples, the intermittent microwave powers intensity process present the optimal processing parameter in microwave drying of Eucalyptus wood species.Keywords: microwave drying; power; intermittent; continuous; Eucalyptus wood.
Determination of the moisture content of white and yellow corn from ohaji in imo state of nigeria using the dry-weight technique
Authors: Chigozie Offurum Julius , Morgan C.M. 
Published: January 2019

The water content determination of two maize species (Yellow corn- and White corn- ) located at Ohaji in Imo State of Nigeria were considered in this study. This was motivated by the regular reported cases of the seed post-harvest spoilages, especially in the local communities. And the moisture content of a particular seed could vary according to the various location of crop, presumably due to the soil texture. The moisture content of a given crop seed can influence its storage value, as well as its choice of selection during manufacturing processes. It was, thus, necessary to determine the moisture content of the two maize species (white and yellow corn) from Ohaji in Imo State of Nigeria, in order to identify their dispositions, especially during storage. Modified High Constant Temperature Oven method, as prescribed by the International Seed Testing Association (which involves preliminary pre-drying and grinding), was employed, at a temperature of 102oC. This involved the use of dry-weight technique, which is expressed as a percentage of the dry weight of the seeds. The procedure for each sampling was replicated accordingly, and the mean value identified as the actual result. The moisture content for Sample A (white corn) was found to be 31.7%, while that of Sample B (yellow corn) was found to be 21.5%, which shows that the yellow corn would always have longer storage value than the white corn. As any change in the seed moisture content has a way of affecting its storage life, it is advisable not to store the white corn longer than it could be applied in the yellow corn for a better storage value.Keywords: Determination, Moisture Content, White Corn, Yellow Corn, Dry-weight Basis

Published: January 2019

Organic acids, sugar and colour define the quality and the taste of mangoes. The quality deteriorates during drying on a single-layer-dryer. Quality losses can be reduced by using drying parameters that influence the quality less. In this research, the contents of ascorbic acid, organic acids and sugar as well as colour changes and shrinkage are analysed. Analyses are carried out at different temperatures, dew point temperatures and air velocities using HPLC, IC and UV/Vis- spectrometry. The quality criteria showed the lowest changes at a temperature of 60°C, dew point temperature of 20°C and an air velocity of 0.9 m/s.Keywords: organic acids; sugars; colour; shrinkage; thin-layer-dryer.

Authors: Tsuruta Takaharu , Ogawa Takuma , Abe Ryosuke , Tanigawa Hirofumi 
Published: January 2019

High quality drying of therapeutic protein-solution is important in medical and pharmaceutical processing. Freeze-drying is mostly used, but it takes a long drying-time and causes damages of protein structures. In order to improve the drying quality, we propose a microwave vacuum drying performed at ambient temperatures under low-pressure conditions. We are focusing on the Parma-Zyme method for the evaporative drying of protein solutions such as egg white or lysozyme with vitrification. Circular dichroism (CD) spectroscopy is used to detect protein conformation changes due to the drying, and it is found that the ambient temperature drying can preserve the protein conformation.

Published: January 2019

Dehydration is widely involved in tobacco processing such as tobacco leaf curing, tobacco trip redrying and cut tobacco drying, which plays a key role due to its effect on the physical and chemical quality of tobacco. The current drying methods in tobacco processing mainly use heat conduction, heat convection or their combination to dehydrate tobacco materials. However, radiation heat transfer as one of basic heat transferways has not been investigated in the tobacco drying. In the present work, infrared radiation dryer was designed to explore the tobacco infrared radiation drying characteristics. The effect of radiation heat transfer conditions and vacuum on the drying kinetics and temperature of tobacco leaves was investigated. Diffusion coefficient of middle tobacco leaves C2F is between 0.848×10-10 ~ 1.597×10-10 m2/s. At the same time, the pore structure andpetroleum ether tobacco extracts in dried tobacco were also analyzed in order to explore the different effects of infrared radiation drying and traditional drying technology on tobacco quality.

Published: January 2019

Nowadays most studies of drying processes dynamics are established on empirical models without clear physical meanings, which could not predict the drying characteristic on different dryers. In order to describe the change of temperature and water content in the cut tobacco in different dryers, a mathematical model based on heat and mass transfer phenomena was developed, and the model employed the relationship of equilibrium moisture content and air humidity as basis, the difference of moisture between biomass and wet air as mass transfer driver, and the difference of temperature between biomass and wet air as heat transfer driver. The drying experiments under different air temperature and humidity are carried out on the batch rotary dryer, and the variance of temperature and moisture content in the biomass is obtained by using infrared thermometer and oven. The model is validated by two parameters with experiment data under each condition of air temperature and humidity. The results show that the drying dynamic model is well on accuracy and universality, and it could be applied on different drying device to predict the characteristic of kinds of drying processes.Keywords: cut tobacco; drying dynamics; equilibrium moisture content; heat transfer; mass transfer.

The results of this study made it possible to have the sorption curves. The results of this study made it possible to obtain the sorption curves necessary for know the storage conditions of the plant and the study of its drying kinetics. The static gravimetric method was used to determine sorption isotherms of Warionia saharae leaves at 30and 40 ◦C and in the range of water activity varying from 0.063 to 0.898. The Gab, Peleg models was found to be the most suitable for describing the sorption curves. The isosteric heat calculated by applying the Clausius–Clapeyron equation .The desorption isosteric heat was higher than the isosteric heat of adsorption and both decreased continuously with increasing of the equilibrium moisture content. The experimental results obtained allowed us to determine the temporal evolution of the drying kinetics as a function of the moisture content. The curve of the evolution of the water content as a function of time shows the absence of the phases product temperature and constant drying rate Keywords: Sorption isotherm, isosteric heats, modelling, kinetics, Warionia saharae.
Comparison between bubbling and turbulent regime for the simulation of batch pharmaceutical powders fluidized bed drying
Authors: Zammouri Amel , Boudhrioua Mihoubi N. , Kechaou N. 
Published: January 2019

The two-phase theory has been frequently used to model fluidised bed drying. At high air velocities, a transition from the bubbling regime to the turbulent regime may occur. In this work, we compare a bubbling model and a turbulent model for the simulation of a two pharmaceutical powders drying in a pilot plant and an industrial plant fluidised bed. The bubbling model was based on a discrete variable bubble size. Heat and mass transfer coefficients were based on the Kunii and Levenspiel correlation [1]. Flow regime was supposed to be completely mixed for the emulsion phase. For the turbulent model, the bubble size is not anymore discrete but continuous and bubble phase is less distinguishable than in the bubbling regime. Heat and mass transfer were those proposed by Foka[2]. In addition, the freeboard section was considered since high entrainment is specific of this regime. Gas backmixing was taken into account by considering a plug flow with axial dispersion for the interstitial gas flow. The bubble phase being dilute, was modeled by a plug flow. A plug flow was also considered for the freeboard gas. The solid phase was supposed to be completely mixed. The bubbling regime simulation gave good agreement with experiment in the case of the pilot plant experiment, while the turbulent model better simulated the industrial scale experiment.

Published: January 2019

Chayote (Sechium edule) is a fruit that is said to be a nutritional and have healing properties. 90% of its weight is made up of water which makes this fruit highly perishable. Convective drying is an excellent option to reduce the loss of this product as well as prolong its shelf life. Thus, the main objective of this work was to assess the physicochemical characteristics of different chayote samples (slices, cubes and strips) during its drying and rehydration process. Results suggest that cubes represent an alternative for commercial use as an additive in foodstuffs due to their size.Keywords: chayote; convective drying; rehydration process; physiochemical properties.
Simultaneous wetting and drying; fluid bed granulation and tablet film coating
Authors: Kemp Ian C , Van Millingen Alex , Khaled Houda , Iler Lewis 
Published: January 2019

Simultaneous wetting and drying occur in processes such as fluid bed (top spray) granulation, Wurster coating and tablet film coating. This gives control challenges, as the spraying and evaporation processes must be carefully balanced and the operating window is significantly narrower than for standalone drying processes. Significant recent advances in modelling have led to effective scale-up and operational strategies. Factors such as flow cessation during filter bag shaking can have a major effect. A design space can be predicted which is often non-orthogonal, and pharmaceutical regulatory authorities have accepted filing submissions using a design space justified by mechanistic modelling.

Published: January 2019

The evaporation of water is a major energy consumer around the world where the evaporation of water from agricultural products, natural resources, processed foods and feeds, and petrochemical products is required for long term storage, subsequent processing or other desired attributes. The control of product attributes associated with drying can also be challenging in terms of measurement and modelling which may lead to inefficiencies in the operation of a dryer. This discussion below will address solutions to improve the thermal efficiency of dryers and to control the critical properties of the product being dried. In addition, the benefits of haring information between the dryer supplier and the dryer operator will be discussed through the use of the Industrial Internet of Thing Keywords: heat recover; design; control.

Published: January 2019

A one stage drying process for dried cranberry production, employing a vacuum microwave technique, is proposed. The process consists of a specific sequence of microwave energy dosage at a given vacuum level. During the 60 minute process, three sub-stages can be identified: osmotic dehydration, intensive water evaporation and stabilization. Mass transfer, as well as quality changes during the process, has been described, and the final product quality compared to purchased control. The proposed method of dried cranberry production resulted in a microbiologically stable product (aw=0.62) of a decent sensory quality, with an antioxidant potential three times higher than traditional products.
