Abstract: A method, in accordance with an embodiment of the present invention, for testing for mastitis in a domestic animal includes the step of measuring, by nuclear magnetic resonance (NMR), a spin-spin relaxation time of milk collected from a quarter of the domestic animal.

Abstract: A mucosal vaccine composition for preventing bovine mastitis, comprising: an antigen derived from Staphylococcus aureus; and a nanogel comprising a polysaccharide having a cationic functional group and a hydrophobic functional group in side chains. By administering the composition to cattle, it is possible to enhance the titer of an antibody against Staphylococcus aureus immediately after the contact with the bacteria in the udder, and prevent the bovine mastitis.

Abstract: To provide an ultrasonic flowmeter that prevents reduction in S/N ratio by suppressing the movement of a damping material applied to the pipe of the ultrasonic flowmeter, an ultrasonic flowmeter is provided. The ultrasonic flowmeter includes a first ultrasonic transceiver provided on a part of an outer periphery on an upstream side of a pipe in which gas flows, the first ultrasonic transceiver transmitting and receiving an ultrasonic wave, a second ultrasonic transceiver provided on a part of the outer periphery on a downstream side of the pipe, the second ultrasonic transceiver transmitting and receiving an ultrasonic wave, a main unit measuring a flow quantity of the gas, an ultrasonic absorber provided on the outer periphery of the pipe, the ultrasonic absorber including a first rubber layer formed on the outer periphery of the pipe and a second rubber layer formed on the first rubber layer.
