Abstract: A method for diagnosing mastitis of cows, includes the steps of (1) irradiating visual light rays and/or near infrared rays in a wavelength range of 400 to 2500 nm into urine, raw milk or a mammary gland of a cow, (2) detecting an intensity of transmitted light rays, reflected light rays or transmitted and reflected light rays from said urine, raw milk or mammary gland, and (3) effecting multivariate analysis while using a classification model based on probability, separability or similarity, and (4) diagnosing the presence of the mastitis of the cow.

Abstract: Benzene, ascorbic acid acting as a reducing agent, and a vanadium-supported alumina catalyst are placed in an aqueous solution of acetic acid used as a solvent, and the reaction is carried out under an oxygen gas atmosphere having a pressure of at least 0.3 MPa so as to directly oxidize benzene and, thus, to obtain phenol at a high yield of at least 8%.

Abstract: Solanum stenotomum, Solanum phureja and Solanum goniocalyx, which are diploid potatoes native to the Andes, are crossed by open pollination, thereby forming a hybrid population rich in genetic variation. The hybrid population is raised while screening the hybrid population on the basis of selection criteria including a yield thereof, thereby reconstituting the hybrid population. The reconstituted hybrid population is raised for seedlings under short-day light conditions while limiting a rhizosphere thereof and controlling the growth at a slightly lower temperature during a potato-tuber growing period. A mini-potato edible whole (including skin) in one bite can be thus obtained.
