Abstract: The disclosure provides an assay for detecting if a subject is seropositive for SARS-CoV-2, or not, comprising incubating a biological sample from the subject with uninfected cells and SARS-CoV-2-infected cells, where the uninfected cells and the SARS-CoV-2-infected cells are distinguishable from each other, to form an admixture, and determining an amount of antibodies in the biological sample bound to the uninfected cells and to the SARS-CoV-2-infected cells, thereby determining whether the subject whose biological sample was tested is seropositive for SARS-CoV-2, or not.

Abstract: An electrode case used to make a self-baking electrode that is consumed in a reducing arc furnace and the electrode made therefrom is described. The electrode case comprises an outer sleeve and a plurality of fins. The outer sleeve is divided into multiple sleeve sections made from a first metal, such that each sleeve section has an outer and inner surface, the multiple sleeve sections capable of being stacked together to form the outer sleeve. The plurality of fins is divided into multiple fin sections made from a second metal, such that each fin section is mechanically coupled to the inner surface of one sleeve section along its length and project radially therefrom along its width. Each fin section has an upper interface region, a central support region, and a lower interface region; the upper, central, and lower support regions having a lattice structure with at least 10% open area.
