  • Publication number: 20140379894
    Abstract: Connectivity is tested using different locations and contexts selected from different possible failure zones. The failure zones may include: client failure zones; Internet failure zones; and online service failure zones. The results relating to different connectivity tests performed using the different failure zones are correlated and analyzed in an attempt to determine a root cause of the connectivity issue. For example, the root cause may be determined to be a configuration problem of the client, a problem with the client's networking equipment, an ISP problem, an Internet backbone problem; a problem of the online service, and the like. Different contexts may also be used when performing the tests. These results may be compared to the other connectivity test results. The results from the tests may be provided to the client experiencing the problem. Aggregated test results may also be used to detect service wide issues and trigger an alert.

  • Publication number: 20140120058
    Abstract: The present invention relates in general to polymer-drug conjugates. In particular, the invention relates to polymer-drug conjugates wherein the conjugated drugs are selected from prostaglandins and substituted prostaglandins, to a method of delivering such prostaglandin drugs to a subject, to a sustained drug delivery system comprising the polymer-drug conjugates, to a method of preparing the polymer-drug conjugates, and to an implant comprising the polymer-drug conjugates.

  • Publication number: 20140046018
    Abstract: The invention relates to a biodegradable polymer comprising a plurality of releasable bioactive moieties, the releasable bioactive moieties being pendant from and covalently bonded to the biodegradable polymer backbone, wherein the biodegradable polymer backbone is formed from monomeric units that are each coupled via a biodegradable moiety, and wherein the bioactive moieties are capable of being released at a rate equal to or faster than the rate of biodegradation of the polymer backbone.

  • Publication number: 20070142576
    Abstract: A polyolefin production system, comprising a polymerization reactor (such as a polyethylene loop slurry reactor) and a fractionation system that receives reactor effluent processed in a diluent/monomer recovery system for recycle to the reactor and to suppliers. A conduit diverts a portion of a reflux flow comprising monomer, such as ethylene, from within the fractionation system to the polymerization reactor, providing for less venting of monomer, such as ethylene, to the supplier. Accordingly, monomer yield is advantageously increased, as the monomer returned to the reactor displaces monomer feedstock to the reactor. The reflux flow may originate from a condensed overhead lights from a diluent recycle column disposed in the fractionation subsystem. The diluent recycle column may receive a stream comprising diluent and monomer as feed from the diluent/monomer recovery subsystem, and may receive the non-diverted portion of the reflux flow as reflux.

  • Publication number: 20060287442
    Abstract: A method for transferring polymer within a polymerization system, comprising continuously withdrawing the polymer from the reactor and conveying the polymer from a reactor to a flash chamber via a pressure differential between the reactor and the flash chamber. A method for transferring polymer within a polymerization system comprising conveying the polymer from a reactor to a flash chamber via a pressure differential between the reactor and the flash chamber and purging interstitial gases from the polymer prior to conveying the polymer from the sash chamber to a purge column. A method for transferring polymer within a polymerization system comprising conveying the polymer from a flash chamber directly to a purge column via a pressure differential between the flash chamber and the purge column.

  • Publication number: 20050034968
    Abstract: Polymer solids are maintained in an intermediate pressure zone for a desired polymer solids residence time and then transferred to a purge zone or other lower pressure zone. An increase in the polymer solids residence time in the intermediate pressure zone allows more diluent to flash or separate, thereby avoiding or reducing the need for a low pressure flash zone. A fluff chamber may be disposed between the intermediate pressure zone and a lower pressure zone. A transporter tank may be used to transport polymer solids after the intermediate pressure zones.
