We address a complex scheduling problem arising in the wood panel industry with the objective of minimizing a quadratic function of job tardiness. The proposed solution strategy, which is based on an effective genetic algorithm, has been coded and implemented within a major Tunisian company, leader in the wood panel manufacturing. Preliminary experimental results indicate significant decrease o...

alkaline crude enzymes from the viscera of the tunisian barbel (barbus callensis) were extracted and characterized. proteolytic crude extract from barbel viscera was active and stable in alkaline solution. the optimum ph and temperature were 11.0 and 55 °c, respectively, using casein as a substrate. the crude alkaline protease was extremely stable in the ph range of 5.0-12.0. zymography activit...

chemokines and their receptors  play an important  role in the  late inflammatory stage of asthma. in this study, we aimed to investigate polymorphisms of mcp-1 (ccl2), ccr2 and ccr5 which can affect qualitatively and/or quantitatively their production and thus influence both susceptibility and severity of asthma and its clinical and biological features. mcp-1   (a/g   -2518),  ccr2   (+/64i), ...

The wave of popular uprisings that spread across the Middle East and North Africa (MENA) in late 2010 brought together a number of societal actors that have since pushed for a significant transformation of their countries. Civil society movements have been at the forefront of this change. However, they currently struggle to define their role and face many obstacles. This Issue Brief explores th...
