摘要:
A heat exchanger including a first header having an inlet therein, a second header, an outlet in one of the first and second headers, and a plurality of flat tubes extending between the first and second headers for carrying a fluid between the first and second headers. A first connector is also provided for connecting a first exterior line to one of the first and second headers, the first connector being proximate and substantially parallel to an end of one of the flat tubes. In a compact cooling system, such heat exchangers may be disposed about a radial fan directing air flow outwardly away from the fan axis. One of a system inlet and a system outlet are connected via the first exterior lines to the first connectors of at least two of the heat exchangers.

An electrical junction box includes a casing, a first installation space, a second installation space, and a connection part arranged in the casing the connection part includes a main body, a first connection end, and a second connection end. The main body is used for connecting to a cable; the first connection end, connected to the main body, is located in the first installation space, and is used for connecting to a contactor; and the second connection end, arranged on the first connection end, is located in the second installation space, and may be used for connecting to a resistance wire. The resistance wire may be connected to the second connection end without passing over the junction box, which is not only advantageous for fastening and installing the junction box, but also facilitates the connection and installation of the cable.

The present disclosure provides transformed human pluripotent stem cell (t-hPSC). t-hPSCs are not dependent on Oct4 for renewal and survival, however exhibit a sensitivity to reduced levels of the transcription factor Nanog. Also provided are methods of culturing cells for use in a cell-based screening assay comprising placing one or more transformed human pluripotent stem cells into a receptacle and culturing said stem cells in the receptacle to form a monolayer of stem cells without cell overlap. Methods of screening compounds using t-hPSCs are also described.
摘要:
A nuclear transfer embryo is formed by destabilizing microtubules of an oocyte, whereby essentially all endogenous chromatin collects at a second polar body during meiosis of an oocyte. The oocyte is fused with the nucleus of a donor somatic cell of the same species of said oocyte prior to cessation of extrusion of the second polar body from the oocyte, thereby forming the nuclear transfer embryo. In one embodiment, the nuclear transfer embryo is employed to impregnate an animal, such as a mammal. In another embodiment, the donor nucleus is transgenic.
摘要:
A compact cooling system including a radial fan directing air flow outwardly and a plurality of heat exchangers disposed around the radial fan. Each heat exchanger has a plurality of tubes extending between an inlet header and an outlet header, with the headers extending generally in the same direction as the fan axis. A system inlet is connected to the inlet headers and a system outlet is connected to the outlet headers, whereby the length of the connection between each heat exchanger and the system outlet and system inlet is generally the same for each heat exchanger.

摘要:
A cooling system includes a radial fan rotatable by an axis to deliver radial air flow to the cooling system, a plurality of heat exchangers spaced radially from the fan and arranged around the fan in a box-like configuration to receive the radial air flow therefrom, with the heat exchangers bounding an interior space of the cooling system. One of the heat exchangers is provided in the form of a charge air cooler that includes a first flow path for a charge air flow in heat exchange relation with a second flow path for an engine coolant flow of the vehicle. The cooling system further includes a surface associated with the charge air cooler to substantially block the radial air flow from exiting the interior space through the charge air cooler.
