a b s t r a c tThe Jeffara escarpment spans 400 km from southeastern Tunisia to sorthwestern Libya, and marks the northern edge of the Berkine-Ghadames Basin. Its horseshoe shape provides a good 3D control of regional-scale depositional architecture. Historically, the political border between Tunisia and Libya hindered the integration of studies over its entirety, which led to the establishment of separate litho-biostratigraphic frameworks. Field-work undertaken on both sides of the border has allowed the unification of lithostratigraphic schemes developed in both countries. Published stratigraphic ages of the different formations and members are compared and integrated in order to propose a unified bio-lithostratigraphic framework. The correlation of serial sections along the Jeffara escarpment shows that two major tectonic unconformities divide the Early Cretaceous sedimentary pattern. The first one is dated as Late Aptian and is commonly associated with the European ''Austrian" tectonic phase. The second, which has previously not been recognized as a regional significant surface in Libya, occurs during the Middle Albian and marks moreover the transition from a siliciclastic to a carbonate-dominated sedimentation regime. These two important regional unconformities form the lower and upper boundaries of the Kiklah-Aïn el Guettar Formations, and can be associated with intra-plate deformation linked with the opening of the central segment of the South Atlantic and the Equatorial Atlantic oceans.

This paper provides an overview of the main technologies currently being investigated in the textile industry as alternatives to contemporary fashion fabrics. The present status of the textile industry and its impact on the environment is discussed, and the key drivers for change are highlighted. Historical use of bioinspiration in synthetic textiles is evaluated, with the impact of these developments on the fashion and apparel industries described. The review then discusses the move to nature as a supplier of new fabric sources with several alternatives explored, drawing special attention to the sustainability and performance aspects of these new sources.

The International Centre for Digital Content explores the relationship of technology to societyóthrough present and emerging applications. This paper outlines ICDCís rapid application development methodology, focusing specifically on a current project partnership with Healthcare Services. The aim of this project is to provide the Primary Care Group (PCG) healthcare specialists with a suite of interoperable devices that can provide breast cancer patients with personalized educational information at any point throughout the course of their treatment. The first phase of the project focuses on the development of a Personal Digital Assistant (PDA) prototype. The patient will have access to educational multimedia content relating to their condition at any time and in any context.
