    摘要： An access device places a medical article within a body space of a patient. The device has a needle that includes an elongated body, a side fenestration on the elongated body, and a needle hub. The device further includes a dilator disposed on and slideable along the elongated body of the needle and a medical article. The medical article is disposed on and slideable along the dilator. The dilator and the needle form one or more spaces in communication with the side fenestration. At least portions of the dilator and the medical article are configured so as to allow visual determination of the presence of a bodily fluid within the space. The outer surface of the needle and the inner surface of the dilator can include a surfactant. Further, at least one of the needle and dilator can further comprise a vent in communication with the space that allows for the escape of air from the space and inhibits the escape of the bodily fluid from the space.

    摘要： A method and electronic device for verifying a user provides for secure speaker verification. The method includes activating a speaker verification process on the electronic device (step 305). A character string is then provided to a user of the electronic device in response to activating the speaker verification process (step 310). Next, an input utterance received from the user within a predetermined time period after providing the character string to the user is processed (step 315). The input utterance is then matched with the character string (step 320) and with stored speech data (step 325). The user is thus verified when the input utterance matches both the character string and the stored speech data.

Particularly, the present invention provides a slurry catalyst directly used in a slurry bed reactor for synthesizing methanol and dimethyl ether and a method for preparing the same, which uses the complete liquid phase preparation from solution to slurry without the conventional slurry-producing process of firstly forming a solid catalyst and dispersing it into an inert medium after crushing and milling. This catalyst mainly comprises Cu, Zn, Al and Zr, wherein atomic ratios of each of components are Cu/Zn/(Al+Zr)=1/0.1-5/0.15-15 and Zr/Al=1:1.0-1:30, and one or two selected from the group consisting of lanthanide metals, Mn, Mo, Si, V, W, Cr, Mg, Ni, K, Pd, Rh, Ru, Re, Pt and Sr is used a promoter. The catalyst prepared in the present invention has the advantages of good stability, high selectivity of alcohol and ether, good rheological behavior and strong wear resistance.
