Identification and Quantification of Stilbenes in Some Tunisian Red Wines Using UPLC-MS and HPLC-DAD
Volume 51 > Number 3 > 2017 Identification and quantification of stilbenes in some Tunisian red wines using UPLC-MS and HPLC-DAD Kamel Arraki *, Élodie Renouf, Pierre Waffo-Téguo, Jean-Michel Mérillon, Tristan Richard and Alain Decendit Université de Bordeaux, Unité de Recherche Œnologie EA 4577, USC 1366 INRA, INP Équipe Molécules d’Intérêt Biologique (Gesvab) Institut des Sciences de la Vigne et du Vin CS 50008 - 210, chemin de Leysotte 33882 Villenave d’Ornon cedex, France Abstract Seven Tunisian red wines mainly from the Mornag appellation were analyzed for resveratrol and analogues. The wines of each variety were evaporated, concentrated, and then subjected to fractionation and purification using XAD16 and DOWEX column chromatography. In addition to resveratrol, seven stilbenes were identified by UPLC- MS. The stilbenes derived were shown to be piceatannol, piceid, α-viniferin, e-viniferin, hopeaphenol and isohopeaphenol. From the point of view of the presence of resveratrol derivatives, one wine, Sidi Zahia, was the richest qualitatively.

Le Corbusier's Cité De Refuge
DOI: http://dx.doi.org/10.4995/LC2015.2015.796 Le Corbusier’s Cité de Refuge: historical & technological performance of the air exacte L.M. Diaz, R. Southall School of Arts, Design and Media, University of Brighton Abstract: Despite a number of attempts by Le Corbusier to implement the combination of ‘respiration exacte’ with the ‘mur neutralisant’ he was never able to test the viability of his environmental concepts in a realised building. The Cité de Refuge, which was built with a more conventional heating system and single glazed facade, is however unique in that unlike the other potential candidates for the implementation of these systems, the building, as built, retained a key design feature, i.e. the hermetically sealed skin, which ultimately contributed to the building’s now infamous failure. It is commonly argued that Le Corbusier, however, abandoned these comprehensive technical solutions in favour of a more passive approach, but it is less well understood to what extent technical failures influenced this shift. If these failures were one of the drivers for this change, how the building may have performed with the ‘respiration exacte’ and ‘mur neutralisant’ systems becomes of interest. Indeed, how their performance may have been improved with Le Corbusier's later modification of a brise-soleil offers an alternative hypothetical narrative for his relationship to technical and passive design methodologies. Keywords: environment, technology, performance, history, Cité de Refuge. 1. Introduction There are two technical building concepts that represent, perhaps more than any others Le Corbusier’s early drive to find comprehensive and exclusively mechanical approaches to the heating and ventilation of modern buildings: a) the mur neutralisant, a double-skin glazed wall with conditioned air circulated within the cavity to moderate heat exchange between the interior and exterior, and b) the respiration exacte, a mechanical ventilation system for providing conditioned air to interior spaces at a constant temperature of 18˚C. -
Nostalgias in Modern Tunisia Dissertation
Images of the Past: Nostalgias in Modern Tunisia Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By David M. Bond, M.A. Graduate Program in Near Eastern Languages and Cultures The Ohio State University 2017 Dissertation Committee: Sabra J. Webber, Advisor Johanna Sellman Philip Armstrong Copyrighted by David Bond 2017 Abstract The construction of stories about identity, origins, history and community is central in the process of national identity formation: to mould a national identity – a sense of unity with others belonging to the same nation – it is necessary to have an understanding of oneself as located in a temporally extended narrative which can be remembered and recalled. Amid the “memory boom” of recent decades, “memory” is used to cover a variety of social practices, sometimes at the expense of the nuance and texture of history and politics. The result can be an elision of the ways in which memories are constructed through acts of manipulation and the play of power. This dissertation examines practices and practitioners of nostalgia in a particular context, that of Tunisia and the Mediterranean region during the twentieth and early twenty-first centuries. Using a variety of historical and ethnographical sources I show how multifaceted nostalgia was a feature of the colonial situation in Tunisia notably in the period after the First World War. In the postcolonial period I explore continuities with the colonial period and the uses of nostalgia as a means of contestation when other possibilities are limited. -
Bugs, Tariffs and Colonies the Political Economy of Wine Trade 1860-1970 Giulia Meloni and Johan Swinnen
Bugs, Tariffs and Colonies The Political economy of Wine Trade 1860-1970 Giulia Meloni and Johan Swinnen Commentator : Ugo Gragnolati How to drive a country thirsty Other than by attempting the debellation of Phylloxera, France coped with wine shortage through trade policies. The combination of these policies explains much of the wine trade in 1860-1970. 1/11 Trade policies ● 1870-1900: Import wine from Spain and Italy, but with growing tariffs from 1890. ● 1875-1900: Import raisins from Greece, but with growing tariffs from 1890. ● 1880-1930: Stimulate wine production in North Africa, but with growing tariffs on Tunisia and Morocco from 1880 and non-tariff measures also on Algeria from 1930. 2/11 Change of trade partners 3/11 Turning point By 1880 grafting and hybridization produced solid outcomes. By 1900, French domestic production had recovered, with two consequences: ● Increasing supply led wine prices to fall between 1880-1905. ● French domestic producers lobbied for protectionism. 4/11 World wars and aftermath 5/11 Question 1: Effect of wine export on locals Did the expansion of vine plantations in North Africa occur on new plots of land or did it substitute other cultivations? 6/11 Question 2: Battling Phylloxera Apparently, the spread of Phylloxera in North Africa was less dramatic than it was in France. Is this an example of laggard’s advantage? 7/11 Question 3: Knowledge transfer Did winemakers in North Africa employ and train the local labor force, or did they import most of it from France? What accounts do we possibly have of knowledge transfer? 8/11 Question 4: Quality and Tunisian export According to the 1890 trade agreement, Tunisian wine exported to France had to be kept below 11°. -

Conçu comme un centre d’accueil et d’hébergement de 282 lits pour sans-abris, ce vaste édifice remplit peu ou prou les mêmes fonctions 80 ans plus tard. Restaurer ce monument historique tout en s’adaptant à un environnement social et humain profondément bouleversé était un véritable pari.

La Maison La Roche Construite Entre 1923 Et 1925 Par Le Corbusier Et Pierre Jeanneret, La Maison La Roche Constitue Un Projet Architectural Singulier
Dossier enseignant Maison La Roche – Le Corbusier et Pierre Jeanneret. Photo Olivier Martin Gambier La Maison La Roche Construite entre 1923 et 1925 par Le Corbusier et Pierre Jeanneret, la Maison La Roche constitue un projet architectural singulier. En effet, l’originalité de cette maison est de réunir une galerie de tableaux et les appartements du propriétaire et collectionneur : Raoul La Roche. La Maison La Roche est située au fond de l’impasse du Docteur Blanche dans le 16ème arrondissement de Paris, dans un quartier qui, à cette époque est en cours d’aménagement. L’utilisation de matériaux de construction nouveaux tels que le béton armé permet à Le Corbusier de mettre en œuvre ce qu’il nommera en 1927, les «Cinq points d’une architecture nouvelle». Il s’agit de la façade libre, du plan libre, des fenêtres en longueur, du toit-jardin, et des pilotis. La Maison La Roche représente un témoignage emblématique du Mouvement Moderne, précédant celui de la Villa Savoye (1928) à Poissy. De 1925 à 1933 de nombreux architectes, écrivains, artistes, et collectionneurs viennent visiter cette maison expérimentale, laissant trace de leur passage en signant le livre d’or disposé dans le hall. La Maison La Roche ainsi que la Maison Jeanneret mitoyenne ont été classées Monuments Historiques en 1996. Elles ont fait l’objet de plusieurs campagnes de restauration à partir de 1970.

They are adhering less and less to the Mediterranean Diet, despite the fact that it is the basis of their identity and one of the major assets of the region. Pressures on natural resources and the emergence of new private actors are compounding the complexity of diet-related issues. THE MEDITERRANEAN DIET > Already the subject of widespread sociocultural and scientific debate and research, the Mediterranean Diet merits reconsideration from the political point of view FOR SUSTAINABLE REGIONAL given the growing awareness of the strategic dimension of agriculture and the crucial role played by food production in the stability and development of societies. DEVELOPMENT This diet, whose health-promoting virtues are widely recognised and which UNESCO has now listed as part of the intangible cultural heritage of humanity, is now raising questions in the fields of environmental responsibility and political action to promote greater regional cooperation.

EEC/TUNISIA COOPERATION AGREEMENT SUMMARY The main object of the agreement between Tunisia and the EEC signed in Tunis on 25 April 1976 is to establish a wide are of cooperation between the two sides and contribute to Tunisia's economic and social development. The agreement covers the whole area of cooperation. This includes not only trade, economic, and technical cooperation, but also social policy and financial aid totalling 95 million European units of account (1 EUA = 2.1 Dinars). (1). Because the agreement is for an unlimited period, there is a stable contractual framework for making long term planning decisions. Projects giving far reaching benefits, e.g., investment in basic infrastructure such as roads and power supplies, as well as measures to open up the Community market to Tunisian exports, can be implemented. The agreement is also dynamic in the sense that it is capable of continuous improvement based on the principle of interdependence, equality, and joint management. -
Ochratoxin a and Ochratoxigenic Fungi in Tunisian Grapes and Wine
IV International Symposium „Agrosym 2013“ 10.7251/AGSY1303686C OCHRATOXIN A AND OCHRATOXIGENIC FUNGI IN TUNISIAN GRAPES AND WINE Samir CHEBIL*, Salma LASRAM, Ahmed MLIKI , Abdelwahed GHORBEL Laboratory of Molecular Physiology of Plants - Borj-Cedria Biotechnology Center. Tunisia *(Corresponding author: [email protected]) Abstract This work summarizes the results of a large study on the occurrence of ochratoxigenic fungi and Ochratoxin A (= OTA) from wine and table grapes in Tunisia. Black aspergilli were the dominant genus among the filamentous fungi isolated from grapes and were the only potential OTA-producing fungi found. The most abundant species were member of Aspergillus niger aggregate than Aspergillus carbonarius. Uniseriate aspergilli were rarely present. Of the A. carbonarius isolates, 97% were OTA positive but only 3% of the A. niger aggregate isolates produce this toxin. During grape maturation, the frequency of black aspergilli increased due to increase of the number of A. carbonarius. Thereafter musts produced from mature grapes were analysed for their OTA content. More than the half of the samples contained detectable levels of OTA, (between 0.01 and 5.85µg OTA l-1). The most contaminated musts were obtained from the region of Raf-Raf located in the North-Est and characterized by a humid climate, however, musts obtained from the region of Regueb located in the center, which is a new area for the grapevine cultivation and characterized with an arid climate were rarely contaminated. For the contamination of tunisian wine, OTA was detected 85% of the analyzed samples. The results show OTA levels ranged between 0.09 and 1.5 µg/L. -
