Abstract: A menstrual device having a storage volume. The menstrual device has a frame and a fluid harrier seal layer attached to the exterior surface of the frame. The menstrual device has an expanded configuration that includes an at rest configuration and a deployed configuration. The menstrual device has a compact configuration where the menstrual device is confined to a size, shape and/or geometry smaller than an expanded configuration such that it can be more easily inserted into the body. The menstrual device in a compact configuration is contained within an applicator, where the applicator assists in ejecting the menstrual device into the body.

Abstract: A string, identifying an item to be assigned to a physical resource, is hashed to obtain a numeric hash value. The numeric hash value is downscaled to obtain a bucket identifier that identifies a bucket that will hold the numeric hash value. The bucket is then deterministically mapped to a physical resource so that it can be retrieved without accessing a stored data structure representative of the mapping.

Abstract: The anthocyanin synthesized from date palm may include co-pigmented anthocyanin complexes synthesized by extracting an anthocyanin from date palm leaves and reacting the anthocyanin with phenolic compounds also resulting from date palm leaf extraction in order to produce a co-pigmented anthocyanin complex. Date palm leaf powder may be mixed with water containing about 1.08% hydrochloric acid in a glass or ceramic lined reactor, and extraction may be performed by boiling the mixture for an hour or more. The color of the co-pigmented anthocyanin complex produced by this method may be adjusted by continuing the heating in half hour increments, in order to deepen the hue of the co-pigmented anthocyanin complex. The co-pigmented anthocyanin complex may be separated from the liquid mixture by first filtering the liquid mixture, refining the liquid mixture by adding gelatin to form a colloidal solution, and freeze-drying the refined liquid mixture.

Abstract: In one aspect, the present disclosure provides a system and method for the identification and characterization of a transglutaminase. Further, the present disclosure provides transglutaminase enzymes for forming isopeptide bonds, methods of forming isopeptide bonds in the presence of transglutaminases, and substrate tags for use with transglutaminases. In another aspect, the present disclosure provides glutamine-containing substrates (or Q-tag substrates) that are more resistant to proteases/clipping and therefore, more stable, than other Q-tag substrates, and their uses in substrate tags for cross-linking to an amine-donor tag via an isopeptide bond mediated by a microbial transglutaminase.

Abstract: A thrust balancing apparatus for a pump includes a housing, a balancing chamber, a connecting tube, a balancing disk, a bushing, a washer, and a pair of upthrust washers.

Abstract: A compact applicator has a two-piece telescoping plunger. The compact applicator, with such telescoping plunger, has a full-size barrel region while maintaining an overall applicator length that is the same and/or slightly shorter than current known compact applicators. In a non-deployed configuration, the inner sleeve of the plunger is generally telescoped within the outer sleeve of the plunger, and the outer sleeve of the plunger is generally telescoped within the applicator barrel.

Abstract: A system and method for detecting, positioning, and tracking objects, including drones, is provided. One provided method includes calculating first estimated location parameters of an object based on a first image from a first image sensor. The method also includes calculating second estimated location parameters of the object based on a second image from a second image sensor. Certain embodiments may also combine the first and second estimated location to determine first physical location parameters of the object.

Abstract: A gold nanoparticle-based assay for the detection of a target molecule, such as Hepatitis C Virus (HCV) RNA in serum samples, that uses positively charged gold nanoparticles (AuNPs) in solution based format. The assay has been tested on 74 serum clinical samples suspected of containing HCV RNA, with 48 and 38 positive and negative samples respectively. The developed assay has a specificity and sensitivity of 96.5% and 92.6% respectively. The results obtained were confirmed by Real-Time PCR, and a concordance of 100% for the negative samples and 89% for the positive samples has been obtained between the Real-Time PCR and the developed AuNPs based assay. Also, a purification method for the HCV RNA has been developed using HCV RNA specific probe conjugated to homemade silica nanoparticles. These silica nanoparticles have been synthesized by modified Stober method. This purification method enhanced the specificity of the developed AuNPs assay.
