Foot and mouth disease (FMD) is a highly contagious disease of cloven-hoofed animals, including cattle, pigs, sheep, goats, and certain wildlife species. The disease can cause massive economic losses when introduced into countries that were free from the infection, generating negative effects due to reduced animal productivity and restrictions on international livestock trade. Following 15 year...

An integrative conflict analysis approach, incorporating an Analytic Hierarchy Process (AHP) based preference ranking method into the Graph Model for Conflict Resolution (GMCR), is employed to investigate the Canadian west coast port congestion dispute. The Canadian west coast has historically been an important gateway connecting North America to Asia thanks to its specific geographical and str...

STOCK DEFINITION AND GEOGRAPHIC RANGE Gray whales formerly occurred in the North Atlantic Ocean (Fraser 1970, Mead and Mitchell 1984), but this species is currently found only in the North Pacific (Rice et al. 1984). The following information was considered in classifying stock structure of gray whales based on the phylogeographic approach of Dizon et al. (1992): 1) Distributional data: two iso...

The Entoprocta is a poorly known lineage of suspension-feeding animals, with 180 described species, most of which are colonial or commensal. A small number of interstitial entoprocts are known, and these are from very few localities in Europe and the eastern coast of North America. We found the solitary entoproct reported here while undertaking a meiofaunal biodiversity survey off the western c...

At the Sidi Bouzid area located in Central Tunisia, Cenomanian-Turonian reservoir rocks are well outcropping, especially in the Jebel el Kébar and Meloussi areas. The present work confirms that these carbonate intervals constitute the lateral equivalent of the Early-Middle Turonian Biréno and Late Turonian-Coniacian Douleb reservoir Members which are included within the pelagic marls of the Tur...

The centipede genus Eupolybothrus Verhoeff, 1907 in North Africa is revised. A new cavernicolous species, Eupolybothruskahfi Stoev & Akkari, sp. n., is described from a cave in Jebel Zaghouan, northeast Tunisia. Morphologically, it is most closely related to Eupolybothrusnudicornis (Gervais, 1837) from North Africa and Southwest Europe but can be readily distinguished by the long antennae and l...

This study presents measurement of changes using image processing techniques, Digital Shoreline Analysis System (DSAS) and Landsat images along the coast of the island of Djerba, Tunisia. Three regions of this island were selected: Rass Errmall, El Kastil and Aghir. Accretions as well as erosion processes were observed in the study areas between 1984 and 2009. The average of the erosion was aro...

The main purpose of this study in order to estimate fat soluble vitamins contents Mackerel fillets from the northeastern coast of Tunisia. Retinol, α-tocophérol and cholecalciferol were analyzed using HPLC system. The experimental procedure used for extraction consisted on saponification, normal phase separation with UV and fluorescence detection for tocopherol and retinol. While cholecalcifero...

Ruta species are known as a potential source of natural products with biological activities. They are used in several fields such as in therapeutic and traditional medicine. In order to contribute to the valorization of these plants, this work investigated the chemical composition and antibacterial activity of the essential oils of Ruta montana and Ruta gravelons growing in tunisia (north o...
