Abstract: The present invention relates to a siRNA drug, a pharmaceutical composition, a siRNA-small molecule drug conjugate, and the application thereof. The siRNA molecules block the life cycle of virus replication by targeting and inhibiting the expression of key genes for influenza viruses, reduce viral infection, and ultimately clear the viruses. The present invention provides a drug based on the siRNA. The drug can be atomized into liquid droplets through an atomizing device, and the liquid droplets reach the lower respiratory tract and the lung by inhalation, so as to inhibit the replication of the influenza viruses. The pharmaceutical composition of the present invention can exert a synergistic antiviral effect through different mechanisms of action.

Abstract: Portable multimedia devices, and techniques for their manufacture, are provided that feature functional parts embedded with a resin matrix that obviates the need for traditional structural components such as midframes and/or outer casings. The resin matrix may be provided through the use of a flowable liquid resin that is flowed around the functional components within a mold cavity. The liquid resin may then be cured into the resin matrix.

Abstract: A non-dispersive infrared gas sensor provides the same light path for light used in a reference mode and a test mode for testing for the presence or concentration of one or more gases. A vacuum is formed in the light pipe in the reference mode. Gas flows into the light pipe before the test mode. The same emitter and detector maybe used for both the test and reference modes. The emitter transmits an electromagnetic wave through the light pipe in both the reference and test modes. The detected signals in both modes are compared to determine the concentration or presence of gas in the light pipe.

Abstract: A ceiling fan D.C. motor includes a stator and a rotor fitted around the outer circumference of the stator. The rotor is composed of a holder, annular base, a plurality of permanent magnets and a cover. The holder has its circumferential edge provided with an annular wall formed inside with an accommodating space, and its upper side formed with an opening. The annular base is secured inside the circumferential wall of the holder and has its circumferential edge disposed with a plurality of engage studs spaced apart, extending longitudinally toward the opening of the holder and respectively formed inside with an insert hole. The permanent magnets are respectively shaped as an arcuate plate with a preset thickness to be respectively positioned between every two adjacent engage studs, restrictedly fixing the permanent magnets in position.
