摘要:
A mono cusped patch for repairing cardiac outflow tract is disclosed in the present invention, which comprises an inner patch, an external supporting patch and a leaflet. An approximate semicircular slit is provided on the inner patch. The inferior border of the leaflet is set between the inner patch and the external supporting patch along the slit. The inner patch, the inferior border of the leaflet and the external supporting patch are stitched together along the slit edge of the inner patch with sutures. The inferior border of the leaflet is fixed between the inner patch and the external supporting patch. According to this special stitching structure, the present invention also provides a valved conduit of good performance. The leaflets of mono cusped patch and valved conduit are sutured with the inner patch/conduit and external supporting patch/conduit to repair cardiac outflow tract, and the inferior border of leaflet is provided between the inner patch/conduit and external supporting patch/conduit, so that the present invention avoids fixing leaflet only with sutures, makes leaflets more durable and improves postoperative longtime treatment effect of patients significantly.
摘要:
A simulated eye capable of being changed between a normal and a dilated state. The simulated eye includes an eyeball, a receiving member, at least one first electromagnets, at least one second electromagnets, and magnetic powder. The receiving member includes a translucent portion and a cylindrical portion. The at least one first electromagnets is received in the cylindrical portion and is adjacent to the translucent portion. The at least one second electromagnets is fixed to the cylindrical portion and engages with the translucent portion to close the cylindrical portion to form a closed receiving space. The magnetic powder is received in the closed receiving space. When the first and second electromagnet operates to move the magnetic powder toward and away from the translucent portion, a size of a color area of the translucent portion is changeable, whereby the simulated eye is changed between the normal state and the dilated state.

摘要:
Nanostructured manganese-containing compositions having reduced manganese dissolution and methods of making and using the same are provided. In one embodiment, a composition of matter comprises a nanostructured oxide or hydroxide doped with Mn4+. The composition of matter can be made by forming a nanostructured oxide or hydroxide material doped with Mn3+ and oxidizing the Mn3+ to Mn4+ to reduce dissolution of the manganese in the nanostructured oxide or hydroxide material. In another embodiment, a method of reducing dissolution of manganese present in a nanostructured MnO2 material comprises: doping a nanostructured MnO2 material with Fe3+ to reduce the dissolution of the manganese.

The present invention also relates to application and usage method in preparing medicaments for treatment of various lesions and ulcers, especially corneal lesions and corneal ulcers.
摘要:
A method for producing a mixture of ethylene and carbon monoxide by contacting ethane and an oxygen source with a catalyst comprising synthetic cryptomelane or octahedral molecular sieve. The method further comprises condensing the alkyl propionate with formaldehyde to produce an alkyl methacrylate.
摘要:
A computer-implemented method and system for improved data flow analysis and optimization are disclosed. The method and system generates data flow analysis information from vectorized processing components, the data flow analysis information including an input information set and an output information set, generates hole information from the vectorized processing components, selects needed holes based on the input information set, the output information set, and the hole information, and modifies a portion of the data flow analysis 10 information by retaining needed holes and removing holes not identified as needed holes from the vectorized processing components.
摘要:
The invention relates to low temperature curable spin-on glass materials which are useful for electronic applications, such as optical devices. A substantially crack-free and substantially void-free silicon polymer film is produced by (a) preparing a composition comprising at least one silicon containing pre-polymer, a catalyst, and optionally water; (b) coating a substrate with the composition to form a film on the substrate, (c) crosslinking the composition by heating to produce a substantially crack-free and substantially void-free silicon polymer film, having a a transparency to light in the range of about 400 nm to about 800 nm of about 95% or more.
摘要:
An arriving cell is admitted when a flow occupancy level is less than a flow minimum threshold. When the flow occupancy level is not less than the flow minimum threshold, a drop probability based on per-class thresholds is applied to determine if the arriving is to be rejected. When the arriving cell is not to be rejected after applying the drop probability based on the per-class thresholds, a drop probability based on per-flow thresholds is applied.
