Characterization of the alginate biosynthetic gene cluster in Pseudomonas syringae pv. syringae
(American Society for Microbiology, 1997-07)
Alginate, a copolymer of D-mannuronic acid and L-guluronic acid, is produced by a variety of pseudomonads, including Pseudomonas syringae. Alginate biosynthesis has been most extensively studied in P. aeruginosa, and a ...
Nature of conduction in doped silicon
(American Physical Society, 1997-02-10)
Via ultrafast optoelectronic THz techniques, we are able to test alternative theories of conduction by precisely measuring the complex conductivity of doped silicon from low frequencies to frequencies higher than the plasma ...
Identification of the inducing agent of the 2,4-dichlorophenoxyacetic acid pathway encoded by plasmid pJP4
(American Society for Microbiology, 1997-01)
The inducing agent of the 2,4-dichlorophenoxyacetic acid (2,4-D) pathway of Alcaligenes eutrophus JMP134 (pJP4) was determined through the analysis of promoterless lacZ transcriptional fusions with tfd structural genes. ...
Flea-borne rickettsioses: Ecologic considerations
(Centers for Disease Control and Prevention (CDC), 1997-07)
Ecologic and economic factors, as well as changes in human behavior, have resulted in the emergence of new and the reemergence of existing but forgotten infectious diseases during the past 20 years. Flea-borne disease ...
Purification and partial characterization of the OmpA family of proteins of Pasteurella haemolytica
(American Society for Microbiology, 1997-01)
This study was conducted to partially characterize and identify the purity of two major outer membrane proteins (OMPs) (with molecular weights of 32,000 and 35,000 [32K and 35K, respectively]) of Pasteurella haemolytica. ...
3-ethoxycarbonyl-5-methoxycarbonyl-2,6-dimethyl-4-(3-nitrophenyl)pyridinium nitrate, dineopentyl 2,6-dimethyl-4-(3-nitrophenyl)pyridine-3,5-dicarboxylate and dihexyl 2,6-dimethyl-4-(3-nitrophenyl)pyridine-3,5-dicarboxylate
(International Union of Crystallography, 1997)
The single-crystal X-ray structures of three oxidation products of 4-(3-nitrophenyl)-1,4-dihydropyridine, namely, 3-ethoxycarbonyl-5-methoxycarbonyl-2,6-dimethyl-4-(3-nitrophenyl)pyridinium nitrate, C18H19N2O6+.NO3-, ...
Demonstrated low radiative loss of a quadrupole ultrashort electrical pulse propagated on a three strip coplanar transmission line
(AIP Publishing, 1997-11-10)
We present an approach for reducing the absorption and dispersion due to Cherenkov radiation on coplanar transmission lines, which does not require the reduction of the permittivity mismatch between the substrate and the ...
