摘要:
A novel hydrogel system is provided. The hydrogel system comprises a biocompatible hydrogel core having dispersed therein a covalently crosslinked polymer matrix. The hydrogel system is useful per se or as an encapsulation system.
摘要:
A clock circuit with delay functions includes a first clock tree and a delay module. The first clock tree provides a first clock signal and includes a first clock root and a plurality of first sub-trees. The delay module is coupled to the first clock root or a designated sub-tree among the plurality of first sub-trees for delaying the first clock signal. The delay module includes at least two delay segments, wherein each delay segment includes a delay and a connection net. The delay time caused by each delay segment is substantially the same.
摘要:
In a particular embodiment, a controller is adapted to perform a garbage collection operation to remove redundant data, to predict a performance parameter associated with performance of the garbage collection operation, and to abort the garbage collection operation when the predicted performance parameter exceeds a threshold.
摘要:
Biomedical materials are encapsulated in ionically crosslinked polymer capsules, preferably alginate microcapsules. The alginate capsules are then subjected, in a liquid vehicle, to an ethylenically unsaturated monomer and an initiator, to induce polymerization of the unsaturated monomer and therey enhance the strength of the capsule wall. The microcapsules can be after-treated with, for example, polysine and alginate to reduce their tendency to elicit an immune response if implanted in an animal. The invention extends to the microcapsules and also to a method of treating or preventing medical conditions in an animal particularly a human, by implanting microcapsule containing biomedical material in the animal.
摘要:
Exemplary emulsion admixture for use in hydraulic cement compositions formed by emulsifying an antifoaming agent, surfactant, and a comb polymer having a carbon-containing backbone to which are attached cement-anchoring members and oxyalkylene groups. A method of making a stable emulsion admixture comprising the comb polymer, as well as a hydraulic cement composition comprising the admixture, are also described.
摘要:
A device is described having a first surface having a plurality of first areas and a second surface having a plurality of second areas. The first surface and the second surface are opposed to one another and can move relative to each other from at least a first position where none of the plurality of first areas, having a first substance, are exposed to plurality of second areas, having a second substance, to a second position. When in the second position, the plurality of first and second areas, and therefore the first and second substances, are exposed to one another. The device may further include a series of ducts in communication with a plurality of first second areas to allow for a substance to be disposed in, or upon, the plurality of second areas when in the first position.
摘要:
In a particular embodiment, a controller is adapted to control read/write access to a storage media including a pre-allocated area having multiple meta-blocks. The controller includes logic adapted to control the multiple meta-blocks as a first in first out (FIFO) circular queue. The logic selects one or more meta-blocks from the multiple meta-blocks based on an order associated with the FIFO circular queue and selectively writes a logical block address (LBA) mapping table to the selected one or more meta-blocks.
摘要:
A power strip has a stationary base, at least one rotating base, at least one pintle and a power cable. The at least one rotating base is mounted rotatably on the stationary base. Each of the at least one rotating base has a top surface facing along a Z-axis and at least one socket mounted on the top surface and selectively covered by the stationary base by rotating each of the at least one rotating base to align with the stationary base. The at least one pintle faces along the Z-axis and rotatably connects the at least one rotating base to the stationary base. The power cable is mounted on the stationary base. The socket may be covered to prevent malfunction and shorting problems due to dust accumulation on the socket and prevent penetration by objects.
