Abstract: This disclosure provides recombinant DNA constructs and transgenic plants having enhanced traits such as increased yield, increased nitrogen use efficiency, and enhanced drought tolerance or water use efficiency. Transgenic plants may include field crops as well as plant propagules and progeny of such transgenic plants. Methods of making and using such transgenic plants are also provided. This disclosure also provides methods of producing seed from such transgenic plants, growing such seed, and selecting progeny plants with enhanced traits. Also disclosed are transgenic plants with altered phenotypes which are useful for screening and selecting transgenic events for the desired enhanced trait.

Abstract: The present invention concerns a polyphonic reproduction of sounds and particularly individual notes produced by musical instruments or the sounds produced by a group of instruments. In the invention the sounds are separated across a notional aural spectrum by using audio signals which vary differentially in amplitude for the varying sound sources. The variation may be caused either electrically or by varying the positions of the transducers picking up the sound sources.

Abstract: This invention provides a method of concentrating a metaliferous ore containing also substantial quantities of pyrites and/or pyrrhotite and/or sphalerite and comprises subjecting an aqueous pulp of the ore to a froth flotation process in the presence of a depressant and in which (1) pyrites and/or pyrrhotite, and/or (2) sphalerite, is depressed by using as the depressant an amine in which at least 20% of the total number of amine groups are tertiary amine groups and in which the number of quaternary amine groups present is zero or is less than one-third the number of tertiary amine groups.

Abstract: A method of concentrating a metalliferous ore containing also substantial quantities of pyrites and/or pyrrhotite and/or sphalerite and comprises subjecting an aqueous pulp of the ore to a froth flotation process in the presence of a depressant and in which (1) pyrites and/or pyrrhotite, and/or (2) sphalerite, is depressed by using as the depressant a condensation product of an aldehyde with a compound containing at least two amine or amide groups.
