Sodium alginates were extracted from brown seaweeds (Cystoseira schiffneri) collected a Tunisian island (Kerkennah, Sfax) in different seasons (December, April, July and September). The structural features antioxidant properties of C. schiffneri sodium (CSSA) characterized. Micro-elementary analysis showed the absence nitrogen sulfur alginate fractions. All isolates high uronic acids (47.4–66.4...

Based on the works elaborated by De Nicolo and Kwast (2002), Schüler (2003), Schüler and Schröder (2003), Gropp and Vesala (2003) and Aglietta et al (2000), this article aims at to study the systemic risk within the European Union. Indeed, the correlation between market model residues have been applied for the purpose of highlighting advancing the interdependence among the European banks domest...

Knowledge development in organizations relies on Sensitive Business Processes (SBPs), which are characterized by a high complexity and dynamism in their execution, high number of critical activities with intensive acquisition, sharing, storage and (re)use of very specific crucial knowledge, diversity of knowledge sources, and high degree of collaboration among experts. In this paper, we propose...

For the purpose of biometric applications, we explore in this paper a new approach to characterize palmprint features. In recent years, the contactless system emerges as a new viable option to address hygienic issues and improve the user acceptance. In this paper, we examine the issues related to the contactless imaging and we propose a new approach for palmprint recognition captured in contact...
