摘要:
A method for forming a semi-solid metal or alloy having non-dendritic grain structures using gas bubbles, includes heating metal or alloy above a melting temperature thereof to provide liquid metal or alloy, flowing gas bubbles through at least one solid medium inserted into or accommodates therein the liquid metal or alloy thereby cooling the liquid metal or alloy to a temperature below the melting temperature thereof while agitating the liquid metal or alloy with the gas bobbles and forming solid fractions therein, and stopping flowing the gas bubbles therethrough when the solid fraction of solid reaches a range of 0.01-0.5 by weight thereby providing the semisolid metal or alloy having non-dendritic grain structures.
摘要:
A method for the detection of alpha (α) thalassemia by the determination of hemoglobin (Hb) Bart's in the hemolysate. The reaction between a specific binding protein (monoclonal antibody) and the corresponding bindable substance (gamma 4, γ4) in an aqueous test sample occurs by applying the known binding affinity of such components for one another.
摘要:
The aromatic compound 2-acetyl-1-pyrroline (2AP) is the major potent flavor component of all aromatic rice. This present invention provides non-naturally occurring plants in which 2-acetyl-1-pyrroline is synthesized at a level greater than in naturally occurring non-aromatic varieties. Also provided are nucleic acids that can be used as molecular markers for selecting plants and fungi which synthesize a greater level of 2-acetyl-1-pyrroline.
