Abstract: A porous electrospun polymeric nanofiber liquid filtration medium, such as an electrospun mats, used for the removal of viral particles (e.g., parvovirus) and other particles in the 18 nm to 30 nm size range from fluid streams, having a mean flow bubble point measured with perfluorohexane above 100 psi. The electrospun medium includes nanofibers having an average fiber diameter of about 6 nm to about 13 nm, and the nanofiber liquid filtration medium has a mean pore size ranging from about 0.01 ?m to about 0.03 ?m, a porosity ranging from about 80% to about 95%, a thickness ranging from about 1 ?m to about 100 ?m, and a liquid permeability greater than about 10 LMH/psi. The high porosity of the electrospun mats enable much higher water fluxes, thus reducing the time required to complete virus filtration steps on a fluid stream.

Abstract: The instant invention relates to a system that in one form is a referral system for use in various healthcare sectors, which utilizes patient profiles, created using patient trackers, to monitor patient follow-up care. The instant invention allows physicians and providers to communicate about patient’s care in its entirety, beginning with the originating provider creating a patient tracker, sharing that patient tracker with referred physicians, and discharging the patient once the patient tracker’s plans have concluded. This uninterrupted flow of communication amongst all providers and physicians allows for a secured method of tracking each patient’s healthcare plan, provides for efficient healthcare referral follow-ups, and updates the originating HCPs records to ensure there are no gaps in terms of patient treatment.

Abstract: An abrasive article may include an organic bond material, abrasive particles contained within the organic bond material and a plasticizer contained within the organic bond material. The plasticizer may include at least one of an aromatic phenyl group, a heteroaromatic furyl group, or a saturated aliphatic hydrocarbon. The plasticizer may further include a polar group.

The electrospun medium includes nanofibers having an average fiber diameter of about 6 nm to about 13 nm, and the nanofiber liquid filtration medium has a mean pore size ranging from about 0.01 um to about 0.03 um, a porosity ranging from about 80% to about 95%, a thickness ranging from about 1 um to about 100 um, and a liquid permeability greater than about 10 LMH/psi. The high porosity of the electro-spun mats enable much higher water fluxes, thus reducing the time required to complete virus filtration steps on a fluid stream.

Abstract: A method and process for the treatment of wastewater containing phosphorous and nitrogen. The wastewater is first anaerobically treated to produce an anaerobic effluent from which insoluble organic carbon is separated to form a sludge rich in organic carbon that is used as a substrate during anoxic treatment of the wastewater by de-nitrifying phosphorous accumulating organisms (DPAO's) and ordinary de-nitrifying organisms. The separation of insoluble organic carbon is normally conducted using a clarifier located intermediate the anaerobic and anoxic bio-reactors. In one embodiment, the ammonia rich clarifier supernatant is directed to an aerobic reactor for nitrification and the nitrate produced is recycled to the anoxic bio-reactor. The final effluent may be membrane filtered to retain nitrifying biomass within the aerobic bio-reactor. The invention reduces overall hydraulic residence time and sludge volume, which results in a smaller, less expensive wastewater treatment system.
