Abstract: An abrasive slurry regeneration method includes: collecting at least a used abrasive slurry containing an abrasive component and a constituent component of a polishing target object discharged from a polishing machine; inactivating a metal ion dissolved in the used abrasive slurry; dispersing the abrasive component and the constituent component of the polishing target object contained in the used abrasive slurry; separating the dispersed abrasive component and constituent component of the polishing target object to remove the constituent component of the polishing target object; and preparing a regenerated abrasive slurry containing the abrasive component.

Abstract: A plant cultivation method including irradiating a plant with first irradiation light including blue light and second irradiation light including red light. A first irradiation period T1 during which the first irradiation light is emitted and a second irradiation period T2 during which the second irradiation light is emitted are alternately provided in time series. The irradiation timings of the first irradiation light and the second irradiation light are determined by using a tide-generating force as an index.

Abstract: A method for producing a plant includes growing a plant from plant cells in which a promoter and a coding sequence under the control of the promoter have been artificially introduced; and selecting the plant in which an amount of phloem tissue is increased 2.0 times or more in comparison with a wild type plant of the same species. The promoter is a promoter for a gene encoding a protein having at least 60% identity with the amino acid sequence of tracheary element differentiation inhibitory factor (TDIF) receptor (TDR) of Arabidopsis thaliana. The coding sequence encodes either (i) a protein having three common sequences composed of the amino acid sequences of SEQ ID NOS: 1 to 3 in this order starting from the N-terminal side, or (ii) a protein having 95% or more identity with the amino acid sequence of SEQ ID NO:5.

Abstract: The invention provides a golf ball having a core and a cover of at least one layer. The core has a cross-sectional hardness which, letting (H?14) be a JIS-C hardness at a position 14 mm in from a surface toward a center of the core, (H?8) be a JIS-C hardness at a position 8 mm in from the surface toward the center of the core, (H?6) be a JIS-C hardness at a position 6 mm in from the surface toward the center of the core, and (H?4) be a JIS-C hardness at a position 4 mm in from the surface toward the center of the core, satisfies the formulas (1) H?14<70, (2) H?8<72, (3) H?6<75, and (3) H?4?H?8>8.

Abstract: The plant is cultivated by introducing, into plant cells, a promoter specifically expressed in the vascular cambium or phloem cells of a plant, and a cell growth-promoting gene encoding a protein that promotes cell growth under the control of the promoter.

Abstract: The invention provides a golf ball having a core and a cover of at least one layer. The core is formed of a rubber composition which includes a polybutadiene-containing base rubber, an unsaturated carboxylic acid and/or a metal salt thereof, an organic peroxide and sulfur, and for which the value of [sulfur (mol)÷available active oxygen content in organic peroxide] is at least 0.01 and not more than 0.019.
