Hydrodistillation assisted by microwave (HDAM) and Head space solid phase micro-extraction (HSSPME) of Myristica fragrans houtt (MF) were investigated. A kinetic study was performed for MF seeds using two techniques (HDAM: Hydrodistillation assisted by microwave and SDAM: steam distillation assisted by microwave). The effect of the cryogenic grinding (CG) showed differences in yields and composition of volatile oils compared to the simple grinding (SG). HDAM–SG (3.4%) and SDAM–SG (2.55%) allowed extraction of substantial amounts of volatile oils in less time compared with HDAM–CG (4.75%) and SDAM–CG (3.8%). The kinetic study (differential and accumulated yields) of essential oil extraction was quantitatively and qualitatively performed showing a significant variation of composition with the extraction time, especially for accumulated yields such as sabinene (31.48–38.78%), α-pinene (12.74–14.09%) and β-pinene (10.01–12.11%). Similarly, the HS-SPME–GC–MS analysis showed also a significant variation of MF seeds volatile composition according some parameters as the type of fibre coating (PDMS: Polydimethylsiloxane and PDMS– DVB: Polydimethylsiloxane divenylbenzene), particle size, grinding mode and the mass used. The chemical groups (monoterpenoids, aliphatic and aromatic alcohols and esters) showed specific behaviour in SPME analysis. SPME sampling parameters were optimized for these components. [less ▲]

Les études contemporaines autour des cultures alimentaires, menées au départ de différentes perspectives disciplinaires, mettent en évidence le dynamisme interne et interrelationnel qui caractérise les gastronomies, plutôt qu’une « pureté » et un « immobilisme » originels (La Cecla, 1998). Cependant, lorsque l’analyse est portée sur le rapport entre alimentation et migration, une essentialisation des pratiques est souvent produite, plaçant ces dernières dans l’un ou l’autre de deux pôles opposés : le modèle alimentaire associé au pays d’origine et celui majoritairement diffusé dans le pays d’accueil. Une évaluation de ces habitudes ainsi que d’une éventuelle résistance au changement, permettrait d’établir la disposition des migrants à « s’intégrer » à la société locale (Bastenier et Dassetto, 1993 ; De Lesdain, 2002 ; Scardella et al., 2003). Dans ce contexte discursif, où l’inclusion des individus dans certains groupes (la communauté majoritaire, la collectivité « saine » etc.) se fait par l’adhésion aux normes locales, les familles issues de la migration performent leur quotidien alimentaire. Bricoler avec ces normes surdéterminées leur permet d’exprimer une créativité qui se met en œuvre à plusieurs niveaux : celui de l’approvisionnement, celui de la préparation des repas, celui de la transmission des savoir-faire entre les générations. Ces dynamiques seront explorées au travers de l’analyse des données collectées lors d’un travail de terrain mené pendant dix-huit mois au milieu d’un groupe de femmes marocaines résidant dans la province de Milan en Italie. Observations et entretiens ont été conduits à la fois dans les maisons et dans les espaces publics. Ils portaient sur les (micro-)pratiques alimentaires entendues comme facteurs centraux dans la définition du Soi, suivant une approche praxéologique à la subjectivation (Warnier, 2001). Grâce à cette analyse, il sera possible de constater qu’un modèle alimentaire composite se redéfinit au niveau familial, bien qu’il ne soit pas exempté de l’effet de dynamiques culturelles, sociales, économiques et politiques plus amples et apparemment structurantes. On assiste en fait à une diversification et innovation des pratiques. D’un côté, avec leurs déplacements pour faire leurs achats, femmes et hommes dessinent des chorégraphies complexes à l’intérieur de la ville, et ils engagent aussi une circulation transnationale de biens alimentaires. D’un autre côté, mères et filles puisent de savoirs et savoir-faire différents et s’appuient sur une pluralité d’outils (mémoire incorporée, bouche à oreille, livres de recettes, internet) pour faire face à leurs exigences alimentaires. Ainsi, les familles continuent d’effectuer un choix actif en matière d’alimentation. [less ▲]

Objectives: To describe the mean voice changes of 22 female teachers during a typical workday, examine the inter- and intra-subject variability, and establish a typology of different voice patterns during the workday. Methods: For each participant, fundamental frequency (F0), harmonics-to-noise ratio (HNR), jitter, and shimmer were measured on sustained vowels at the beginning and at the end of the workday, at three different times during the school year. Results: The group mean pattern showed significant increases in F0 and HNR during the workday and significant decreases in jitter and shimmer. However, considerable inter- and intra-subject variability was observed. Based on the variation in the acoustic parameters during the workday, three different voice patterns were identified. The first is characterized by a greater F0 increase during the day, interpreted as a common, appropriate adaptation to vocal load. The second is characterized by a greater increase in HNR during the day and greater decreases in jitter and shimmer, interpreted as hyperfunctional voice production. The third is characterized by greater decreases in F0 and HNR and greater increases in jitter and shimmer, suggesting acute inflammation or muscle fatigue following the workday. Conclusions: The observed variety of vocal patterns during the workday emphasizes the need to study this phenomenon individually and target different types of behaviors in order to develop tailored prevention and treatment methods.

L’oeuvre de Rimbaud peut largement s’envisager à travers le prisme d’une parole magique, performative et créatrice de possibles : au fil de compositions hantées par le motif de la magie, des « flots abracadabrantesques » du « Coeur volé » jusqu’à l’« Alchimie du Verbe », le poète cherche à s’affranchir de la tradition pour tenter d’« arrive[r] à l’inconnu », selon la formule programmatique de la lettre à Demeny du 15 mai 1871. Dans la même missive, ce qui s’énonce d’abord comme un projet prométhéen (« Le poète est vraiment voleur de feu ») se résume en trois mots supposant davantage un engagement dans l’expérimentation : « Trouver une langue. » Au poète de tenter, d’éprouver, de faire bouger les cadres et de secouer les structures établies. La présente contribution envisage les rouages de la poésie rimbaldienne en matière d’incantation à l’aune d’une poétique du détournement. [less ▲]

Of all the royal families of ancient or modern fame, few are as iconic as the eighteenth dynasty of pharaohs of the New Kingdom of Egypt, whose opulence and deeds we are still familiar to nearly 3,500 years after their time. Tenth pharaoh of this dynasty and father of Tutankhamun, Akhenaten (Amenhotep/Amenhotep IV) still fascinates Egyptologists and history lovers through the many questions surrounding his atypical rule. One of the most striking aspects of the so-called Amarna period concerns the representations of the pharaoh himself, very confusing compared to the traditional iconography of the New Kingdom. These intriguing portraits of Pharaoh raised a whole lot of medical assumptions, more or less substantiated. We review here the main theories developed throughout history. [less ▲]

The present paper focuses on the development steps of heat exchangers dedicated to single room ventilation unit with heat recovery (SRVHR) by proposing a numerical approach. A methodology is suggested in order to determine the best trade-off between hydraulic and thermal performance given a specific geometry. The methodology consists in a mapping of the coefficient of performance (COP) of the unit. The latter is defined as the ratio between recovered heat and the fan energy use, given a specific indoor/outdoor temperature difference. However, the energy performance should not be the only criterion to be taken into account in the frame of the design steps of a heat recovery exchanger: technical, economic and acoustic aspects should also be considered. This numerical methodology is illustrated by means of a real example of a newly developed heat exchanger dedicated to a SRVHR. The optimization is first performed while using a semi-empirical model (based on the use of correlations and on a spatial division of the studied heat exchanger). The semi-empirical model allows for the creation of a COP map in order to identify the most effective geometry parameters for the heat exchanger. The decision concerning the final geometry is made accounting for the so-called technical, economic and acoustic considerations. A discussion on some parameters needed for the COP establishment is also proposed. [less ▲]

Common clay deposits from five localities in Foumban (West Cameroon) were investigated for their morphological, mineralogical and geochemical properties to determine their potential source rocks and suitability in ceramic product. The analytical results were obtained by X-ray diffraction, X-ray fluorescence spectrometry, Thermogravimetric Analysis, Scanning Electron Microscopy, and Fourier Transform Infrared Spectrometry. Morphologically, an homogeneous clayey layer was found in the upper part of a laterite cover on interfluves, and a clayey heterogeneous hydromorphic material in valleys. They are minerallogically composed of kaolinite (25-84%), illite (0-18%), smectite (0- 31%), and chlorite (0-8 %), associated with quartz (2-44 %), K-feldspars (0-27 %.), plagioclase (0-26%), goethite; (0-9%) with traces of rutile and hematite (≤5 %). The geochemical analysis shows a 115 relative large amount of SiO2 (45-71%), Al2O3 (14-31%), and low Fe2O3 (up to 11 %) suggesting weathering of mainly granitic and rhyolitic parent rocks. Most studied clays could be applied to building ceramic product such as bricks (refractory or not) and tiles. Illite may promote the glassy phase responsible for the densification of the final product. In addition, the relatively high proportion of alkali elements (K2O + Na2O, 6-8%) in some samples from Marom, Koutaba and is responsible for low firing temperature. However the presence of smectite (up to 5 %) limits the application of some Koutaba and Marom clays for ceramic building. The high Fe2O3 contents (> 8 %) in some Bangourain clays implied some pretreatment. [less ▲]
