Abstract: Polyazacrown polymers based on the azacrown monomer 1,4,7,10,13,16,21,24-octaazabicyclo[8.8.8]hexacosane (“H6Aza222”) are disclosed. Azacrown monomer units are preferably linked with a suitable linking agent, and the resulting polymers are can absorb mercury from a water stream and form a stable complex therewith. Methods of making and using the polyazacrown polymers are also disclosed. The polymers have a high absorption capacity for and selectivity towards mercury, which properties are useful for the remediation of mercury-contaminated water. The polymers can be regenerated by the efficient removal of the absorbed mercury. Further, the absorbed mercury that is liberated from the polyazacrown polymers can be effectively concentrated and captured to prevent its re-release into the environment.

Abstract: A mechanism controls global synchronization, or registration floods, that may result when a large number of endpoints in a Voice over Internet Protocol (VoIP) network such as an Internet Protocol Multimedia Subsystem (IMS) come online simultaneously after a catastrophic failure. The mechanism allows the Domain Name System (DNS) infrastructure to efficiently control the overload condition by registering user end points with backup border elements, and by staggering and by randomizing the time-to-live (TTL) parameter in registrations with backup border elements.

Abstract: A mechanism is provided for recovering from a catastrophic failure that results in a large number of user endpoints attempting to come on line simultaneously after an NGN is restored. In an enhanced DNS load balancer, DNS queries from the user end points relating to a particular NGN edge device are selectively dropped if a rate of queries for the particular edge device suddenly increases or exceeds a threshold. The query dropping may also be based in part on the class of service assigned to the user endpoint.

Abstract: The invention provides a method, system, and program product for discovering relevant information in a dynamic information system (DIS). An illustrative method according to the invention includes comparing information provided by the user to information in a network, determining whether the network contains information relevant to the information provided by the user, and displaying to the user an object containing the relevant information.

Abstract: This invention discloses the concept of a dynamic metasystem managing a dynamic system, achieved through the use of, and an environment (i.e., tools and ontologies) supporting dynamic artifacts. A system for generating a dynamic information system comprises a persistent dynamic repository of data and an integration metasystem. The repository forms an asymmetric navigational database, and the database includes an ontology model. The ontology model has an abstract model framework that supports creation and use of multi-dimensional and asymmetric abstract models of data, and views which define the content and form of presentation of that data using a computer. The integration metasystem includes components that describe components of shared infrastructure and services of an enterprise architecture, and a dynamic information system software tool generating artifacts representing information and views that define the presentation of data.

Abstract: A process for the preparation of propylene glycol from glycerol by a high pressure and temperature hydrogenation reaction is described. In a particular embodiment, a base is present in the solvent mixture with an alkanol or ether of the alkanol. The reaction progresses over a transition metal catalyst. Propylene glycol is used for antifreeze and deicing compositions.

Abstract: A process for producing compound 1,4,7,10,13,16,21,24-octaazabicyclo[8.8.8]hexacosa, 4,6,13,15,21,23-hexaene (2) and then compound 1,4,7,10,13,16,21,24-octaazabicyclo[8.8.8]hexacosane (1) from compound (2) is described. The process uses a reaction between triaminoethylamine and glyoxal in the presence of water, alcohol and tertiary amine at low temperature to produce compound 2. Then compound 1 is produced from compound 2 by reduction with an alkali metal containing ammonia as the reductant. The compounds are aza cryptands which are used to bind metals and the like for electrides, and in alkalides, medicine and water treatment, for instance.

Abstract: Hexose and pentose monosaccharides are degraded to lactic acid and glyceric acid in an aqueous solution in the presence of an excess of a strongly anionic exchange resin, such as AMBERLITE IRN78 and AMBERLITE IRA400. The glyceric acid and lactic acid can be separated from the aqueous solution. Lactic acid and glyceric acid are staple articles of commerce.

Abstract: A process for the separation of a polyol or multiple polyols in admixture with other organic compounds, usually those produced with the polyol, is described. The process uses a distillation in a column (11) of a cyclic acetal from an aqueous solution which acetal is formed in a reaction mixture of the polyol and an aldehyde or ketone. The polyols, such as ethylene glycol and propylene glycol, are staple articles of commerce with many uses.

Abstract: Apparatus and method of manufacture therefor for containing heated substances without cover deformation. The apparatus has a container bottom and a lid member, where the container bottom has integrated within it a support structure such that when the lid member engages the container bottom, the support structure provides additional support to the lid member. The integrated structural support can be provided substantially at the area of the container bottom where the lid member, when attached, has relatively weak support at a predetermined temperature range.
