摘要:
Organic-inorganic composites were prepared as colloidal particles of a cross-linked, thermally responsive polymer. Hybrid PNIPAM-polysiloxane particles and composite polymeric particles with embedded nanoparticles of an inorganic metal-oxide (MOx) such as CeO2 and TiO2 were formed. To promote the incorporation of unaggregated nanoparticles, temperature responsive microspherical gels (microgels) of N-isopropylacrylamide (NIPAM) with interpenetrating (IP) linear chains of poly(acrylic acid) (PAA) were used. The organic-inorganic composition of the hybrid polymer network was controlled by changing the time for condensation and hydrolysis of the siloxane monomer during synthesis. Experimental results indicated that the planarization of silicon oxide wafers using these hybrid particles and composites exhibited lower topographical variations and surface roughness as compared to slurries consisting of only silica or ceria nanoparticles while achieving similar removal rates and better or similar frictional characteristics.
摘要:
Disclosed are complexes of an antipneumocystic compound and an antimalarial compound, processes for their preparation, pharmaceutical compositions and methods of using said complexes or compositions for the treatment and/or prophylaxis of parasitic infections.
摘要:
Disclosed herein are biodegradable hydrogel scaffolds for use in tissue engineering. The hydrogel scaffolds are composed of synthetic terpolymers complexed with polyvinyl alcohol (PVA), which facilitate cell-sheet and tissue growth. In the presence of a monosaccharide, the PVA-hydrogel is dissolved and cell-sheets are released for harvesting. Further disclosed herein are methods for producing PVA hydrogels which support tissue growth. Tissue engineering applications and methods are also disclosed.
摘要:
A query cache stores queries and corresponding results of the queries, the results of the queries being derived from a primary store. A differential store stores a pointer to data of the primary store which has changed and which affects the result of the queries stored in the query store. A new query may be satisfied by accessing the corresponding query in the query store and determining, by reference to the differential store, whether data relating to the query in the primary store has changed since the query store was compiled and, completing the new query, by accessing the corresponding data in the primary store, if applicable. Data in the differential store may be arranged and partitioned according to labels. The partitioning may be varied according to predetermined rules.
摘要:
New compounds, namely, (7aS,2′S)-2-oxoclopidogrel and its pharmaceutically acceptable salts thereof are disclosed for treatment or prophylaxis of thrombo-embolism and/or cardiovascular diseases.
摘要:
A method includes providing identifying information for a customer premises communication device to a provider network, wherein the customer premises communication device is a node of a customer premises network. The method may further include registering a communication channel between the customer premises communication device and the provider network. In addition, the method may include receiving at least one service alert message from the provider network using the communication channel. The type of service alert message is selected based on the customer premises communication device.

摘要:
A consumable compressed tobacco product adapted to dissolve in an oral cavity. The compressed tobacco product is formed from a composition that includes at least one tobacco component, at least one flavorant, at least one filler-binder, at least one lubricant, at least one desiccant and at least one glidant. The compressed tobacco products are adapted to dissolve and provide tobacco satisfaction. A method of making a dissolvable compressed tobacco product is also provided.
摘要:
An approach is provided for monitoring traffic over a network link that is used to provide one or more services to one or more customers. A determination is made regarding whether a failure mode of the network link has occurred by comparing the monitored traffic to predetermined bandwidth criteria. A corrective action to be taken in response to the failure mode is selected, where selection of the corrective action to be taken is determined based on the failure mode. Further corrective actions selected iteratively from a predetermined list of successive actions are applied until the failure modes are addressed.
