Abstract: A pet sheet includes a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body disposed between the liquid-permeable top sheet and the liquid-impermeable back sheet. The liquid-impermeable back sheet has an adhesive surface. The liquid-permeable top sheet, the liquid-impermeable back sheet, and the absorbent body are disposed such that a light transmittance is 60% or less. The pet sheet is configured to be overlaid on an animal excrement disposal sheet.

Abstract: The present invention relates to an iridium complex compound represented by the following formula (1): in the formula (1), Ir represents an iridium atom, R5 to R14, R21, and R22 each independently represent a hydrogen atom, D, F, Cl, Br, I, or a substituent group, the groups adjacent to each other may be further bonded to each other to form a ring, and any one of R12 and R13 is a substituent group represented by the formula (2).

Abstract: According to an allele determining device 1 that determines a single nucleotide polymorphism of a gene, an approximating unit 4 approximates an optical measurement result obtained by observing a reagent that reacts with a specific base sequence of a gene, to a logistic curve that is a curve using light intensity and time as parameters. A determining unit 5 determines a single nucleotide polymorphism using a plateau value or an inflection point that is a characteristic point of the approximated logistic curve, the measured light intensity, and the like.
