Rebeccamycin is an indolocarbazole class inhibitor of topoisomerase I. In the course of structure-activity relationship studies on rebeccamycin derivatives, we have synthesized analogs with the sugar moiety attached to either one or both indole nitrogens. Some analogs, especially those with substitutions at the 6' position of the carbohydrate moiety, exhibit potent inhibitory activity toward checkpoint kinase 1 (Chk1), a kinase that has a major role in the G(2)/M checkpoint in response to DNA damage. Some of these compounds retained a genotoxic activity either through intercalation into the DNA and/or by topoisomerase I-mediated DNA cleavage. We explored the structure-activity relationship between these compounds and their multiple targets. These rebeccamycin derivatives represent a novel class of potential antitumor agents that have a dual effect and might selectively induce the death of cancer cells. [less ▲]

A ball dropped over a solid surface bounces several times before a complete stop. The bouncing can be reduced by introducing a liquid into the ball; however, the first rebound remains largely unaffected by the fluid. Granular materials can also work as dampers. We investigated the rebound of a container partially filled with a given mass of grains mi. During the collision, the kinetic energy of the container is partially transferred to the grains, the rebound is damped, and the fast energy dissipation through inter-particle collisions and friction decreases the bouncing time dramatically. For grain-filled cylinders, a completely inelastic collision (zero rebound) is obtained when mi≥1.5εomc, where εo and mc are the coefficient of restitution and mass of the empty container. For grain-filled spheres, the first rebound is almost undamped, but the second collision is completely inelastic if mi>>mc. These findings are potentially useful to design new granular damping systems. [less ▲]

This paper presents the reframing approach developed by Michel Monroy. His approach deals more particularly with the reframing of conflictual situations experienced within the frame of a family as well as at work.

Rooting of wild-type tobacco (Nicotiana tabacum cv. Xanthi) shoots raised in vitro was promoted by polyamines in the absence of any other growth regulator and was inhibited by two inhibitors of polyamine metabolism. The auxin insensitive and recalcitrant to rooting rac mutant shoots did not respond to the same treatments. The activities of arginine decarboxylase (ADC), ornithine decarboxylase (ODC), diamine oxidase (DAO), polyamine oxidase (PAO) and transglutaminases (TGases), and the titres of free and conjugated polyamines were estimated in the whole shoots and the basal parts of the stems of both tobaccos in the course of multiplication in vitro. The rac shoots grew at a lower rate. The wild-type rooted from the 7th day without special treatment. During the second week of culture, the shoots of both tobaccos were actively growing and showed an increase in ADC, ODC, DAO, PAO and TGase activities. Afterwards all these activities declined. These changes were concomitant with an increase in the polyamine contents (free and conjugated). Biosynthesis and oxidation of polyamines apparently occurred simultaneously and seemed directly correlated. In the basal part of the mutant stems however, the accumulation of free and conjugated putrescine as well as the transient increase in biosynthetic enzyme activities were delayed compared to the wild-type. These results are discussed in relation to growth behaviour and to root formation. (C) 2000 Editions scientifiques et medicales Elsevier SAS. [less ▲]

Several findings showed that semantic information is more likely to be retrieved from recognised faces than from recognised voices. Earlier experiments, which investigated the recall of biographical information following person recognition, used stimuli that were pre-experimentally familiar to the participants, such as famous people’s voices and faces. We propose an alternative method to compare the participants’ ability to associate semantic information with faces and voices. The present experiments allowed a very strict control of frequency of exposure to pre-experimentally unfamiliar faces and voices and ensured the absence of identity clues in the spoken extracts. In Experiment 1 semantic information was retrieved from the presentation of a name. In Experiment 2 semantic and lexical information was retrieved from faces and/or voices. A memory advantage for faces over voices was again observed. [less ▲]

In this paper, a receding-horizon multi-step optimization is proposed to correct non viable transmission voltages and prevent long-term voltage instability. The proposed control scheme is based on real-time control, inspired by model predictive control, and steady state power-flow-based equations. In order to anticipate load behavior and avoid using dynamic equations in the control scheme, explicit formulations are used to model evolution of load with time. The simulation results of the proposed technique are presented on the Nordic32 test system. [less ▲]

Le prix de revient de la structure métallique d'un navire réside principalement dans la main d'oeuvre nécessaire à l'assemblage des pièces et éléments constitutifs. Deux gisements importants de réduction de ce prix sont : - minimiser le coût inhérent à chaque opération (mécanisation, outillages, méthodes, précision, formation ouvrier, ...) ; - minimiser le nombre de ces opérations en diminuant le nombre d'éléments à assembler. Aux Chantiers de l’Atlantique, le premier axe fait depuis plusieurs années l'objet de nombreuses actions et on souhaite aujourd'hui explorer plus avant le second thème. Avant d'envisager la faisabilité et la rentabilité d'actions fortes dans ce domaine, une étape préliminaire visant à établir une connaissance plus fine des éléments constitutifs est nécessaire, c'est à cette première phase que nous avons apporté notre contribution. L’objectif de l'étude est d’établir un recensement et une caractérisation des pièces constitutives de la structure métallique d'un navire à passagers afin de mettre en lumière, le cas échéant, les gisements potentiels d’économie. Deux axes d’études ont été choisis. Le premier s’oriente vers une analyse du « produit fini », le second s’oriente vers la « phase de production ». Il s’agit plus précisément, pour l’analyse du « produit fini » de recenser et caractériser en nombre, en masse, en distribution géographique et en niveau de sollicitation, les pièces constitutives des grandes familles structurelles d’un paquebot de référence choisi parmi les plus récents. Par exemple, il sera question de quantifier le nombre et le poids des pièces constituant les ponts. Par contre, pour l’analyse orientée vers la « phase de production », il s’agit de déterminer et de repérer à quel stade de production les pièces du pont sont montées et vérifier la pertinence de leur lieu de montage. Par exemple, il sera question de quantifier le nombre et le poids des pièces constituants chaque panneau. En final, nous proposons des pistes d’investigation visant à réduire le nombre de pièces constructives s’intégrant dans la structure métallique des paquebots et à en fournir tous les éléments nécessaires à leur analyse.
