Abstract

The present invention addresses the problem of providing: a technology that enables the homeostasis capacity in environments such as soil or in water to be continuously monitored; and a technology for predicting and quantifying the feeding amount for fish and other animals being raised in an environment, on the basis of the measurement results of the homeostasis capacity in the environment. As a means for solving the problem, provided is an environment homeostatsis measurement device which includes a potentiometer comprising an FTO electrode or an ITO electrode. Also provided is a feeding system comprising: a potentiometer that comprises an FTO electrode or an ITO electrode and that is disposed in the bottom material; a feeding device that supplies feed into water; and a control unit that controls the feeding device so as to adjust the feeding timing and/or feeding amount on the basis of the value of the potential measured by the potentiometer.

Abstract

By making the oil droplet diameter of a DHA-containing oil-based component in a mousse at least 20 µm, excellent absorbability of DHA into the body can be achieved. By producing a DHA-containing mousse such that the mousse includes a DHA-containing oil-based component with an oil droplet diameter of at least 20 µm, it is possible to provide a DHA-containing mousse that offers highly efficient absorption of the DHA-containing oil-based component into the body, is easy to chew, and enables DHA to be ingested efficiently and easily through meals.

Abstract

The purpose of the present invention is to provide a method for producing selenoneine with which it is possible to produce selenoneine on an industrial scale because selenoneine can be produced at a higher yield than in the prior art. This purpose is achieved by a method for producing selenoneine that includes a step for obtaining selenoneine by subjecting histidine and a selenium compound to the action of a transformant into which a gene that encodes an enzyme of (1) is inserted and which overexpresses the inserted gene. (1) An enzyme that catalyzes a reaction for producing hercynylselenocysteine from histidine and selenocysteine in the presence of S-adenosylmethionine and iron(II)

Abstract

Provided is a transverse metacenter height estimation device that includes: a history storage means for storing time sequence data of the roll angle of a hull; and a transverse metacenter height estimation means that estimates the transverse metacenter height of the hull on the basis of the time sequence data of the roll angle of the hull, such data stored by the history storing means. The transverse metacenter height estimation device is characterized in that the transverse metacenter height estimation means first calculates a roll natural frequency on the basis of the time sequence data of the roll angle of the hull, sets the calculated roll natural frequency as an observation model, carries out state estimation on the basis of a normal state spatial model in which the transverse metacenter height and the gyration radius of the hull are used as state variables, and thereby estimates the transverse metacenter height.
