    Abstract: A method for detecting genes sensitive to low-level ionizing radiation and genes detected by the method. More specifically, genes sensitive to low-level ionizing radiation and related to suppressing thymic cancer, discovered in a carcinogenic entity and verified in a normal entity are detected by subjecting a cancerous AKR/J mouse and a normal ICR mouse to low-level radiation. Thymus is collected therefrom, immunogenic and apoptotic genes are classified via microarray processing of the thymus. The genes are amplified and the levels of gene expression are measured. Thus, a gene having a specific reaction to radiation can be accurately detected by preventing the interference of confounding variables.

  • Publication number: 20190085414
    Abstract: Provided herein is a dual amplification method for detecting plant pathogens by analysis of pathogen DNA in an unpurified nucleic acid sample from the plant. Pathogen-specific primers are used to generate a first set of amplicons that are further amplified in a second amplification step using fluorescent tagged pathogen-specific primers. Fluorescent amplicons thus generated are hybridized with pathogen-specific nucleic acid probes that are immobilized on a solid support using bifunctional polymer linkers. The hybridized microarray is imaged to obtain fluorescent images of the amplicons and the nucleic acid probes, which are superimposed to detect the pathogen present in the plant. Also described herein is a method to simultaneously detect both plant DNA and pathogen DNA in a single assay.

    Abstract: Heat treatment of DRI is performed in order to form a DRI product with a metallic shell around at least a portion of the DRI. The heat treatment may be delivered through the use of a plasma torch, a gas burner, an oven, or any other like heat source. The heat treatment may heat the DRI for a fraction of a second and quickly cool the DRI in order to melt the surface and form the metallic shell without vaporizing a significant portion of the DRI and without losing a significant amount of the latent energy in the DRI. During storage and transport of the DRI product, the DRI product is less likely to fracture, the DRI product has less exposed surface area of DRI, and results in reduced DRI fines and/or DRI dust cause by the DRI product rubbing together when compared to traditional types of DRI.

    Abstract: “A method for thermally treating a flat steel product, a thermally treated flat steel product and use thereof. The method includes providing a flat steel product with a structure with a first hardness. The flat product is heated at least in sections to an austenitizing temperature. The heated flat product is cooled at least in sections so that a structure with a second hardness is formed within the flat product at least in sections, the second hardness having a higher level of hardness in comparison to the structure with the first hardness. The heating and the cooling down of the flat product are coordinated with each other such that the structure with the second hardness is formed across the thickness of the flat product and at least in one of said sections, the structure with the first hardness remains constant across the thickness of the flat product.
