摘要:
The invention provides a metalworking oil composition which is used for a very small amount of oil-feeding type metalworking method, said composition comprising a base oil selected from the group consisting of natural fats and oils, derivatives thereof and synthetic ester oils; and an antirust agent comprising a sorbitan fatty acid ester and a phospholipid, and a metalworking method using the composition and metalwork obtained by the metalworking method. The oil composition shows excellent lubricity and antirust property and is suitably used for metalworking of metallic materials such as cast iron, steel, stainless steel, and nonferrous metal (such as Al alloy and Mg alloy) by a method in which a very small amount of oil is supplied.

A method of selecting a barley variety comprising: a heat treatment step of heat-treating a crude enzyme solution extracted from a seed of a barley (e.g., at 57.5° C. for 30 minutes); an activity-determining step of determining the enzyme activity of β-amylase in the crude enzyme solution heat-treated; and a selection step of selecting the barley variety containing a β-amylase having a residual activity of from 85 to 90% as a result of the activity determination.
摘要:
An object of the present invention is to provide a novel solid reagent capable of solving the problems of conventional solid reagents based on resin beads.The present invention relates to a solid reagent comprising an organic polymer base in which a polymer side chain is introduced onto the backbone of the organic polymer base via graft polymerization and a reactive functional group is introduced onto the polymer side chain. The organic polymer base is preferably in the form of a fiber, a woven or nonwoven fabric consisting of an assembly of fibers, a porous membrane or a hollow fiber membrane. The graft polymerization is preferably a radiation-induced graft polymerization. Solid reagents according to the present invention can be used in various organic synthetic reactions.

An object of the present invention is to provide a separation functional material having more excellent adsorptive separation performance than previously. In order to attain this object, separation functional materials of the present invention are characterized in that they are formed by introducing a polymer side chain derived from a p-haloalkylstyrene onto the backbone of an organic polymer base and introducing a functional group onto the polymer side chain.
摘要:
The present invention provides a method for determination of the foam stability of a fermented malt beverage, wherein the concentration of protein Z7 (MZ7) in seeds of a barley which is used as a material for the fermented malt beverage, a malt obtained from the seeds, a wort obtained from the malt, a fermented malt beverage obtained by fermenting the wort, or a pre-fermentation or fermenting material solution of the fermented malt beverage, is used as an index having a negative correlation with the foam stability of the fermented malt beverage, to determine the foam stability of the fermented malt beverage. According to the determination method of the invention, it is possible to determine the foam stability from the concentration of a prescribed protein in the barley seeds, malt, wort, fermented malt beverage or the like without directly measuring the head retention of the fermented malt beverage.
