[Problem] To provide a new technology that enables reducibility to be maintained for a prolonged period of time.

[Solution] A composition having reducing ability, comprising a substance having reducing ability and a wet ball mill-treated product of yeast cell wall and/or a hydrothermal reaction-treated product of yeast cell wall.

A solids interceptor and methods of using the same. The solids interceptor includes a tank including an open end, a wastewater inlet, and one or more wastewater outlets. A basket assembly is removably attachable to the tank via the open end between an operable position and a removed position. The basket assembly may seal the open end when in the operable position and expose the open end of the tank to a surrounding environment when in the removed position. A first and second outlet may extend away from an interior of the tank in a first and direction, respectively, with the second direction being oriented at an angle with respect to the first direction. The basket assembly may include a seal that is compressed about a circumferentially extending corner provided on the tank to thereby seal the open end of the tank and the plumbing system.

This invention has an object to provide a method for producing a beryllium solution by dissolving beryllium oxide, the method being novel and having high energy efficiency. A production method (M10) for producing a beryllium solution includes a main heating step (S13) of dielectrically heating an acidic solution containing beryllium oxide to generate a beryllium solution.

A fluorescent member includes: a wavelength converter including an incidence part on which a light of a light source is incident and an output part from which a converted light subjected to wavelength conversion as a result of excitation by an incident light is output; and a reflecting part provided in at least a portion of a surface of the wavelength converter. The wavelength converter is comprised of a material whereby a degree of scattering of the light of the light source incident via the incidence part and traveling toward the output part is smaller than in the case of a polycrystalline material.
