Abstract: L'invention concerne un procédé de préparation de polyestercarbonates, dans lequel un mélange d'au moins un carbonate de diaryle activé réagit dans des conditions de polymérisation avec au moins un composé dihydroxy aromatique avec au moins un acide dicarboxylique. On obtient ainsi des polyestercarbonates possédant jusqu'à environ 10 % en mole de résidus d'acide dicarboxylique en fonction de la quantité totale d'unités structurelles dérivées de composés de dihydroxy aromatiques. Ce procédé fournit des niveaux élevés d'incorporation d'acide dicarboxylic dans le squelette de polyestercarbonates et un niveau élevé de coiffage terminal des polymères.

Abstract: Network nodes (10, 15, 20, 25, 30 40) of a communication network (100) determine whether the queue position (56, 57) of a data packet (60) exceeds a threshold (55). Data packets which are placed in a queue that has a depth greater than the threshold, and therefore will experience increased delay at this node, are remarked to a higher priority for expedited handling at the next hop. The next hop network node which handles that data packet will put it in a higher priority queue (51) such that it will experience less delay at the that node. In this way, a negative correlation in node-to-node delay is achieved and overall delay variation is reduced.

Abstract: L'invention concerne un procédé de forage d'un trou à l'aide d'un fluide de forage présentant les avantages d'un fluide de faible viscosité en matière de pompabilité et ceux d'un fluide très visqueux en termes de capacité de suspension des déblais de forage. De plus, la viscosité de ce fluide peut être ajustée facilement et rapidement, de sorte que la rhéologie dudit fluide peut être adaptée en cours de forage à mesure que les conditions souterraines varient. Pour obtenir ces avantages, on ajoute à ce fluide un polymère réticulable de manière réversible et un activateur de réticulation encapsulé. Cet activateur de réticulation provoque la réticulation après l'introduction du fluide dans le trou de forage. Ensuite, on détruit cette réticulation à la surface du puits, de manière à réduire la viscosité du fluide et à permettre un retrait aisé des déblais de forage. Un activateur de réticulation est à nouveau ajouté au fluide et ce dernier est réintroduit dans le trou de forage. On peut ajuster la quantité d'activateur de réticulation et/ou de polymère réticulable dans le fluide pour modifier sa rhéologie afin d'adapter ce fluide aux variations des conditions du puits qui sont surveillées en temps réel.

Abstract: In an image projection on a screen, an image projection
apparatus improves the safety of entry into a proj ection region
by the human body and does not bring about the increase of
complexity of the configuration thereof owing to the
improvement of the safety. A monitoring area is regulated
on the outside of the projection area (3) of the screen (2).
A detection wave such as infrared rays is emitted from a
detection wave source (1c) of the image projection apparatus
(1) . A reflection wave from the monitoring area is detected
by reflection wave detection means (1d) such as a CCD sensor.
Whether the human body or an obstacle enters the monitoring
space, which is surrounded by a detection wave (4) between
the main body unit of the image projection apparatus (1) and
the screen (2), or not is detected. Once the entry is detected,
the intensity of the radiation light traveling toward the
projection area (3) is reduced or cut off according to the
situation or the degree of the entry.

Abstract: Anti-swirl baffles are provided in a mass transfer column to reduce the swirling motion of a vapor or mixed phase feed stream introduced into the column. The column is of the type having an upper region of a preselected diameter, a lower region of reduced diameter, and an intermediate transition region that has a diameter that transitions from the preselected diameter of the upper region to the reduced diameter of the lower region. The column includes a vapor or mixed phase feed nozzle and a feed device such as a vapor horn located at least partially within the upper region for delivering the vapor or mixed phase feed stream into the column. The anti-swirl baffles are positioned in the intermediate transition region of the column to disrupt the swirling motion of the vapor or mixed phase feed stream as portions of it descend from the feed device into the transition region of the column. An annular shield positioned in the transition region and spaced inwardly of the column shell defines a liquid flow passage that is shielded from the swirling motion of the vapor or mixed phase feed stream to reduce liquid entrainment.

Abstract: L'histone désacétylase est une métallo-enzyme comportant du zinc au niveau de son site actif. Les composés possédant un groupe caractéristique de liaison au zinc, par exemple un groupe alpha-chalcogenméthylcarbonyle, tel qu'un groupe alpha-cétothio, peuvent inhiber l'histone désacetylase. L'inhibition de l'histone désacétylase peut réprimer l'expression de gènes, notamment l'expression de gènes associés à la suppression des tumeurs. En conséquence, l'inhibition de l'histone désacétylase peut constituer une voie détournée de traitement du cancer, des troubles hématologiques, par exemple des hémoglobinopathies, des affections autosomiques dominantes, telles que la maladie d'Aran-Duchenne et la maladie de Huntington, des troubles métaboliques d'origine génétique, tels que la mucoviscidose et la leucodystrophie avec insuffisance surrénale, ou un moyen de stimulation ex vivo des cellules hématopoïétiques.

Abstract: Toner compositions have a post-blended particulate additive which comprises aluminum oxide and aluminum hydroxide with, optionally, a third component such as silica or a wax, which is a tribo-charging additive which, upon tribo-charging of the toner particles, shifts the charge distribution in either the positive or negative direction. As well as providing toner compositions having adequate fluidity, the use of pre-extrusion charge-control additives can be avoided. There are also advantages, for example, in terms of charge distribution characteristics, stability of charge distribution, and avoidance of matting effects. Developer compositions are formed by admixture with suitable carrier particles.
