Abstract: An iron carbide heat source, particularly useful in smoking articles, is provided. The iron carbide particles making up the heat source have ignition temperatures that are substantially lower than conventional carbon particles normally used in carbonaceous heat sources, while at the same time provide sufficient heat to release a flavored aerosol from a flavor bed for inhalation by the smoker. In a preferred embodiment, the iron carbide heat source of this invention is substantially cylindrical in shape and has one or more fluid passages therethrough. Upon combustion, the heat source produces substantially no carbon monoxide.

Abstract: Improved expression vectors for amplifying expression of DNA sequence encoding a desired polypeptide beyond that expected by the vector copy number. The vector contains a DNA sequence within the replicon of the vector encoding RNA I and the primer RNA for initiation of DNA replication and their regulatory regions, said DNA sequence having an AT to GC mutuation at position 3029 in the two strands of pBR322; a promoter of RNA I or primer RNA and a restriction site for insertion of a DNA sequence encoding a desired polypeptide into the vector and operatively linking the DNA sequence to the expression control sequence. The AT to GC mutation causes an increase in the vector copy number and further amplifies the expression of the desired polypeptide operatively linked to the RNA I or primer RNA promoter beyond that expected by the copy number increase.
