Abstract: A millimeter-wave active antenna unit and an interconnection structure between PCBs is provided. The interconnection structure between PCBs comprises a mainboard and an AIP antenna module. The mainboard is a first multilayer PCB on which a signal transmission line and a first pad electrically connected to the signal transmission line are provided. The AIP antenna module is a second multilayer PCB on which a second pad, an impedance matching transformation branch, an impedance line and a signal processing circuit are provided. The mainboard and the AIP antenna module are interconnected by directly welding multiple PCBs.

Abstract: A method utilizing a humic acid substance for renovating and afforsesting slag is provided. A humic acid substance may be utilized for passivation, adsorption, reduction, chelation and immobilization of harmful heavy metal elements in slag, for example, Cr, As, Cd, Ni, Pb, Ba, Hg, Co, Se, Ag and Be, and aggregating the slag, thereby detoxifying the slag and producing artificial earth. The artificial earth may be used in combination with a carrier bacterial fertilizer to continuously produce the active humic acid substance, achieving an effect similar to the combination of blood transfusion and blood production, thereby forming a high-quality artificial soil.

Abstract: Providing a environment-friendly and in situ immobilized method of renovating heavy metal contaminated soil with humic acid substance, comprising: while the heavy metal contaminated soil being pulverized, adding humic acid substance into the soil according to weight ratio 5-20:1 of the humic acid substance to the total heavy metals contained in the soil, then aging the soil for more than 24 hours after the pulverization process; 2) adding 1-3 parts by weight of semi-coke bacterial fertilizer to 100 parts by weight of the water-stable granular structures, and mixing uniformly.

Abstract: An immunoassay suitable for point of care to assess liver disease or function comprising contacting a blood sample from a subject with a specific binding agent that recognizes an epitope of ALT1, that is not recognized by rodent antibodies when the rodent antibodies are in the presence of human plasma, to form an antigen-binding agent complex and detecting the complex using a second or further binding agent linked to or comprising a detectable reporter; and detecting liver disease or liver function in the subject contingent upon the mass concentration of ALT1 in the sample. Kits or devices comprising lagomorph antibodies or binding agents comprising the antigen binding component thereof suitable for measuring the mass concentration of ALT1 in a blood sample from a subject to determine liver function.
