Abstract: An ultrasonic preparation method of protein peptide-polysaccharide nanoparticles loaded with bioactive components is conducted as follows: Chitosan solution containing 1% glacial acetic acid is added gently to the casein phosphopeptide solution containing quercetin stock solution in an equal volume under constant magnetic stirring; pH is adjusted accordingly before subjecting the mixture solution to ultrasonic treatment; after ultrasonication, the quercetin-loaded casein phosphopeptide-chitosan nanoparticles are obtained by freeze-drying. In the process of using the electrostatic interaction between the casein phosphopeptide and the chitosan to embed the quercetin, the present disclosure employed the multi-mode ultrasonic processing technology to facilitate the cross-linking of the polypeptide and the polysaccharide through the physical force of ultrasound. This enabled the complex encapsulation to incorporate additional bioactive components.

Abstract: Embodiments described herein provide for evaluating call metadata and certificates of inbound calls for authentication. The computer identifies a service provider indicated by the SPID and/or the ANI (or other identifier) of the metadata and identifies a service provider indicated by the SPID and/or ANI (or other identifier) of the certificate, then compares identities of the service providers and/or compares the data values associated with the service providers (e.g., SPIDs, ANIs). Based on this comparison, the computer determines whether the service provider that signed the certificate is first-party signer (e.g., carrier) for the ANI or a third-party signer that is signing certificates as the first-party signer for the ANI.

Abstract: An anode for a zinc metal battery and a zinc metal battery using the same are provided. An anode for a zinc metal battery includes a zinc metal film and a protective layer formed on a surface of the zinc metal film, and the protective layer may be zinc phosphate.
