This invention provides novel nanofiber enhanced surface area substrates and structures comprising such substrates for use in various medical devices, as well as methods and uses for such substrates and medical devices. In one particular embodiment, methods for enhancing cellular functions on a surface of a medical device implant are disclosed which generally comprise providing a medical device implant comprising a plurality of nanofibers (e.g., nanowires) thereon and exposing the medical device implant to cells such as osteoblasts.

This invention provides novel nanofiber enhanced surface area substrates and structures comprising such substrates for use in various medical devices, as well as methods and uses for such substrates and medical devices. In one particular embodiment, a method of administering a composition to a patient is disclosed which comprises providing a composition-eluting device, said composition-eluting device comprising at least a first surface and a plurality of nanostructures attached to the first surface, and introducing the composition-eluting device into the body of the patient.

Protective garments that can keep the front of the wearer's clothes clean and dry are provided. The bibs include a substantially overlapping slit formed in the center of a lower section of a front panel. The bibs with the slit are easy to put on and provide substantial coverage of frontal position of a wearer. The bibs can be used during eating, drinking, sitting, playing, crawling, etc. In some examples, the open back can enable the bib to be easily slipped on an already seated person without the need to stand. One or more bibs provide the ability to fasten the apron around each leg separately resulting in mobility and coverage, as well as the ability to use in seating where there is a vertical obstruction between the legs.

A soil cutting head for a mount of an agricultural implement includes a head having a leading extremity for cutting into soil ahead of the mount, and a fertilizer tube extending through the head to a discharge end for discharging a stream of fertilizer into the soil from the head.

The invention relates to a straw comprehensive utilization method, and belongs to the technical field of biomass raw material comprehensive utilization. The method mainly comprises the following key steps: straw cutting treatment, dry-process dedusting, hot-water washing for sand removing, continuous cooking, spraying and receiving, multi-stage countercurrent washing, multi-stage high-concentration pulp grinding, fiber classification treatment, long-fiber concentration, long-fiber curing treatment, long-fiber pulp grinding and production of corrugated paper through long fibers, short-fiber concentration, and enzymolysis, fermentation and distillation of short fibers for production of fuel ethanol and solid granular fuel. The method has the beneficial effects that high-value comprehensive utilization of all components of the straw material is realized, chemicals are not added, a water system is closed and circulated, and the zero discharge of wastewater is realized; the specific surfacearea of a fine fiber component is large, and the enzymolysis efficiency is high; corrugated paper produced by the long fiber component is high in strength and good in quality; when the fine fiber component is used for an enzymolysis system, not only is the enzymolysis property of the material improved, but also the cost of enzymolysis sugar is greatly reduced, so that the development of a biomasscomprehensive utilization technology is promoted.

The present invention discloses a frequent item set mining method based on frequent pattern tree for localized differential privacy protection, which is applied to a scenario where an untrustworthy third-party data aggregator A and n users form, and the steps include: S1, initialization stage; S2, data pruning stage; S3, tree building stage; S4, data mining stage. The present invention can estimate all frequent itemsets and corresponding support degrees satisfying a given support threshold under the condition that the third-party data aggregator A does not hold any user privacy record information, thereby ensuring that the third party can dig out useful information based on the obtained results. association rules to provide support for possible decisions.
