Abstract: A high-altitude wind power generation system with a cycloidal turbine and a motor-generator, and a method of operating the same. The system includes a buoyant apparatus configured to be inflated when buoyancy generating gas is injected therein; a cycloidal turbine configured to be placed under the buoyant apparatus, and comprise a rotary shaft arranged to be substantially horizontal to the ground, and a plurality of blades arranged along a circumferential direction of the rotary shaft while their pitch center lines are long extended to be parallel with a center line of the rotary shaft and are spaced apart from the rotary shaft at a preset distance as being arranged to be substantially perpendicular to a flowing direction of fluid blowing from a front, having pitch angles individually adjustable with respect to the pitch center line; and a motor-generator configured to connect with the rotary shaft of the cycloidal turbine.

Abstract: The present invention relates to a displayable wind turbine. The displayable wind turbine includes a central shaft arranged vertically to a flow direction of fluid. Radially extending upper spokes are coupled to an upper hub. Radially extending lower spokes are coupled to a lower hub. Blades have first ends connected to an end of the upper hub and second ends connected to an end of the lower hub. A pitch control unit adjusts a blade pitch angle. A detection unit includes a fluid direction detection unit, a fluid velocity detection unit, a central shaft speed detection unit, and a central shaft position detection unit. A light emitting unit includes a printed circuit board and light emitting devices. A control unit controls operations of the pitch control unit and the light emitting unit.

Abstract: The presence of diverse human Papillomavirus genotypes in a sample can be detected by 1 cycle of polymerase chain reaction using primers. The primers used in the method are general primers which can bind complementarily to specific nucleic acid sequences of all HPV genotypes related to cervical carcinoma and its pre-stage lesions and can be used to amplify cervical-neoplasia related HPV genotypes including oncogenic high-risk groups and low-risk groups.
