Abstract: The invention provides a special launching carrier with variable position platform and a method for bridge erection using the same. The special launching carrier with variable position platform comprises a special carrier for erection bridge beam and an under-bridge machine with platform. The special carrier for erecting beam comprises a main beam, a front wheel group, a rear wheel group and a lifting device; the under-bridge machine with platform comprises a under-bridge, a rotatable rear leg, a front roller, a middle roller, a rear roller and an erecting trolley arranged on the under-bridge, and the variable position platforms are installed on both sides of tail portion of the under-bridge. When erecting bridge beam, the front wheel group moves onto the variable position platforms, which may be elevated and folded in terms of conditions of the first and last spans of different bridges, so that the bridge erection is achieved.

Abstract: The present invention relates to a heat-dissipating fin capable of increasing surface turbulence, which includes a first heat-dissipating fin and a second heat-dissipating fin. A first surface of the first heat-dissipating fin is provided with a plurality of first protrusions arranged at intervals. The second heat-dissipating fin has a second surface toward the first surface. The second surface is also provided with a plurality of second protrusions arranged at intervals. The second protrusions are arranged to correspond to the first protrusions. The second heat-dissipating fin is overlapped with the first heat-dissipating fin. With the arrangement of the first protrusions and the second protrusions, the heat-dissipating area of the first heat-dissipating fin and the second heat-dissipating fin can be increased so as to increase the surface turbulence. Thus, the heat-exchange efficiency can be enhanced.

Abstract: A tissue homogenizer. The tissue homogenizer comprises a first chamber, a pair of blades, a first filter and a second filter. The first chamber has a first opening and a second opening. The blades are disposed in the first chamber. The first filter is disposed in the first chamber between the first opening and the blades. The second filter is disposed in the first chamber between the second opening and the blades. A tissue piece is placed between the first filter and the second filter cut by the blade, and moved by a fluid through the second filter to generate homogenized tissue pieces.

Abstract: A bioreactor system. A supply container receives a cultivation solution. A bioreactor container is connected to the supply container and includes a porous carrier. The porous carrier carries a plurality of cells. The cultivation solution circulates between the supply container and the bioreactor container, providing needed nutrients to the cells.

Abstract: In an implementation of a viewing selection management system, a first viewing selection is displayed as a primary display, such as on a display device. A task input corresponding to a new or pending task is received where the task input is an accept task input, a pause task input, a deny task input, or no input. If an accept task input is received, the new or pending task is displayed as a second viewing selection within the primary display, such as picture-in-picture display. If a deny task input is received, the new or pending task is deleted, and if a pause task input or no task input is received, a new task is stored on a stack memory and a pending task continues to be maintained with the stack memory.

Abstract: A heat sink structure, having a heat sink and a thermal conductive block. The heat sink has a receiving slot recessed from a central portion of a bottom thereof. The thermal conductive block has a plurality of uneven surfaces thereon and a plurality of conical through holes therein. The thermal conductive block is pressed into the receiving slot while the heat sink is softened by heating, and the heat sink has a thermal expansion coefficient larger than the thermal conductive block, such that a wall of the receiving slot is partly extruded into or through the conical through holes, and the wall outside of the conical through holes is partly contracted into the conical holes in a cooling process after the thermal conductive block is pressed into the receiving slot. The conical through holes also provides the function of expelling gas, such that the thermal conductive block is firmly attached to the heat sink, and the heat dissipation effect is further enhanced.
