Abstract:
The invention relates to a system and a method for tracking and executing a job comprising a series of tasks. Each task is executable on a separate computing device. The method comprises: utilizing a workload manager to identify an initial schedule of implementation for the job; utilizing agents to selectively control execution of the tasks; and for each agent, utilizing a publish/subscription interface to isolate communications of the workload manager from each agent and to communicate with other publish/subscription interfaces of other agents to determine when to activate its task. The interface utilizes a broker adapted to communicate with other brokers to disseminate communications amongst the agents.

Abstract:
Disclosed are degradable materials including molded products, laminates, foams, nonwoven materials, adhesives, coatings and films, and particularly packaging films. The materials are made using polydioxaneone polymers comprising at least two different dioxaneone-based repeating units. Preferred polymers are polydioxanediones. First repeating units have less carbon atoms in constituent groups extending from the polymer backbone than second repeating units. Physical characteristics and degradation of the materials can be varied by varying the choice and/or relative proportions of first and second repeating units in the polydioxaneone polymers. Methods for preparing polydioxaneone polymers that can be used in the manufacture of the materials are also discussed, as are suitable monomers and methods for preparing such monomers.

Abstract:
The invention is concerned with a hidden image product, an identification device which shows the hidden image information, an identification system, the produce method of the produce and the identification equipment, the identification equipment contains a single layer or multi-layer lens with the specified array micro-structure. The produce contains the array pixels with same-level array-distance corresponding with the identification equipment array micro-structure. The selected area of the array pixels and the identification equipment array micro-structure has the entirely or partly controlling phase excursion, shows the micro-structure or the hidden image in the pixel when the array of pixels of the product or the array of the identification equipment array micro-structure is superposition or spacedly squaring with distance. The invention overcomes the low anti-false precision and the inconvenience of the existing hidden image identification technique.
Abstract:
Disclosed is a novel integrated process for production of cyclic esters which includes recovery of starting materials, such as lactic acid from a dilute aqueous lactic acid-containing solution, by solvent extraction. The starting materials are then formed into cyclic esters by removal of water wherein the concentration of higher molecular weight oligomers is maintained below about 20 wt % of the reaction composition. The process further includes providing a recovery solvent for the reaction composition and separating the cyclic esters from the starting materials and higher molecular weight oligomers by liquid-liquid equilibrium separation. The present invention is further directed toward independent novel unit operations of the overall process. The present invention provides for the efficient production and recovery of cyclic esters due to integration of the various unit operations by use of appropriate solvents and recycle streams. In addition, high rates of conversion of starting materials and high rates of selective production of cyclic esters are achieved by appropriate control of process parameters.
Abstract:
Disclosed is a method for producing cyclic esters by the conversion of hydroxy carboxylic acids and their derivatives to their respective cyclic esters. Such cyclic esters, including lactide or glycolide, are particularly useful for producing polymers which can be used to make biodegradable materials, such as biodegradable packaging material. Various methods of cyclic ester production are disclosed, including liquid phase and vapor phase reactions. Also disclosed are various methods for recovering cyclic esters from product-containing streams.
