  • Publication number: 20180338513
    Abstract: Disclosed is a method for removing benzo[?]pyrene from a liposoluble natural extract. The method of the present invention comprises adding a suitable solvent to a crude natural extract product so as to obtain a mixed material; heating the mixed material, stirring until uniform, cooling and layering, and then separating the upper layer from the lower layer so as to obtain a precipitate and a filtrate; washing the precipitate with a small amount of a solvent so as to obtain a washed product and a washing solution; removing the solvent from the washed product at a low temperature so as to obtain a finished product; and directly recycling the filtrate and the washing solution as solvents. The present method achieves the purification of the crude natural extract product and the removal of benzo[?]pyrene in one step, and is a novel method which is simple, highly efficient, feasible and easy for industrial applications.

  • Publication number: 20170315203
    Abstract: The present disclosure is directed to methods and systems for fusing Phase Contrast Angiography (PCA) with anatomic images to create a perforator PCA (pPCA) data set. In the pPCA) method, vascular and anatomic information may be provided by different MRI sequences. A four-point acquisition scheme may be used for 3D PCA acquisition of vascular images. Anatomical MRI images are acquired and may be enhanced with image post-processing techniques. The vascular and anatomical images may be combined with image fusion to create a high resolution map of abdominal wall vasculature. This high resolution map visualizes not only the size and location of the DIEP perforators, but also their relationship with surrounding tissue, and the blood flow velocity within them. As such, the fused pPCA image has substantially higher SNR and CNR than CTA image of the same slice thickness.

  • Patent number: 8599831
    Abstract: The invention discloses a method for establishing a session between a caller and a callee, applying to a next generation network, after said callee picking up, which includes: restarting a session negotiation with said callee via a first application server corresponding to the callee, upon obtaining a session description protocol of said callee, sending an update request message containing a session description protocol of said callee to a second application server corresponding to the caller; renegotiating, by the second application server, session with a caller according to said session description protocol of said callee; after the caller completing session update, returning a response message containing a session description protocol of said caller to said callee. The method can realize the multi-service nesting triggering or the forwarding triggering of several flows in one service, and can guarantee the proper connection between the caller and the callee.

  • Publication number: 20080273671
    Abstract: A method and a system for preventing a crosstalk of color ring back tone are provided. When a plurality of entities in the network provide a color ring back tone service for a call simultaneously, an Application Server determines whether a ring back tone or prompt tone of a called party needs to be screened according to a predefined strategy. If the ring back tone or prompt tone of the called party needs to be screened, the Application Server screens the ring back tone played by the called party according to service logic and plays a ring back tone provided by the value-added service to the calling user. An Application Server is also provided.
