In this paper we present an algorithm for approximating the range of the real eigenvalues of interval matrices. Such matrices could be used to model real-life problems, where data sets suffer from bounded variations such as uncertainties (e.g. tolerances on parameters, measurement errors), or to study problems for given states. The algorithm that we propose is a subdivision algorithm that explo...

In order to distribute new multimedia applications on a high scale, the mostly used and analyzed wide area networks (WAN) are the Internet on one side and ATM based networks on the other side. One of the current research activities in the networking area consists in trying to federate the Internet new mechanisms / protocols (IP new Generation : IPnG) and the ATM ones, in order to allow applicat...

ERCIM News is the magazine of ERCIM. Published quarterly, it reports on joint actions of the ERCIM partners, and aims to reflect the contribution made by ERCIM to the European Community in Information Technology and Applied Mathematics. Through short articles and news items, it provides a forum for the exchange of information between the institutes and also with the wider scientific community. ...

Objective: Alpha-glucosidase, as a carbohydratase catalyses the liberation of alpha-glucose from the nonreducing end of some carbohydrates from foods in digestive tract.  Consequently, retard absorption of glucose by the inhibition of carbohydrate hydrolyzing enzymes is one of the therapeutic approaches to decrease the postprandial hyperglycemia. Recently, a great deal of attention has been pai...

The glucosinolate autolysis products of crushed seeds of DesclIrainia sophia L. (khakeshi) and Brassica napus L. (shelghem) were administered orally to rats in doses representing 8,16 and 32 gm seeds/kg body weight/day at intervals of 10, 20 and sometimes 30 days. Serum T3 and T4 concentrations were reduced in 10 day•autolysate treated animals in a similar fashion to that found with methim...
