  • REFRIGERATOR
    Publication number: 20220282901
    Abstract: A refrigerator is proposed. Due to a first heater provided in a damper assembly, a damper assembly or the connection portion of the damper assembly with a supply duct is prevented from freezing, and due to a second heater provided in the supply duct, the connection portion of the supply duct with the damper assembly or the inside of the supply duct is prevented from freezing.

  • Nano-neurotoxicity bio-marker composition based on intracellular aggregates which are biomarkers of degenerative brain diseases
    Patent number: 11261475
    Abstract: A method of assessing neurotoxicity of nanoparticles, includes: preparing a tissue or cell sample of mammal exposed to the nanoparticles; analyzing at least one polyamine metabolite selected from the group consisting of putrescine, N1-acetylspermidine, N8-acetylspermidine, N1-acetylspermine and spermine in the sample; and comparing expression degree of the polyamine metabolite with that of a control.

  • REFRIGERATOR
    Publication number: 20210172670
    Abstract: A refrigerator includes a cabinet, an evaporator, a shroud, a grille panel coupled to a front surface of the shroud, and a blower fan module disposed between the grille panel and the shroud and configured to blow the cool air from the evaporator toward a freezing compartment. The blower fan module includes an installation frame defining a first plane that faces a rear surface of the grille panel, and a second plane that faces the front surface of the shroud, a hub part that is rotatably coupled to the second plane of the installation frame and faces an inlet hole of the shroud, and a blower impeller disposed in the hub part.
