Nonlinear picosecond-pulse propagation through optical fibers with positive group velocity dispersion
(American Physical Society, 1981-09-28)
The predictions of the nonlinear Schrodinger equation have been tested by passing 5.5-psec optical pulses through a 70-m single-mode optical fiber. With use of a precise cross correlation technique based on pulse compression, ...
Mucoid conversion by phages of Pseudomonas aeruginosa strains from patients with cystic fibrosis
(American Society for Microbiology, 1984-05)
A total of 21 of 22 independent isolates of cystic fibrosis-associated Pseudomonas aeruginosa were found to be lysogenic for DNA-containing, complex capsid viruses. Several of the phages demonstrated the ability to select ...
Microwave sterilization of plastic tissue culture vessels for reuse
(American Society for Microbiology, 1982-10)
A simple protocol has been developed for recycling plastic tissue culture vessels. The killing properties of microwaves were used to decontaminate plastic tissue culture vessels for reuse. Nine bacterial cultures, four ...
Optical pulse compression based on enhanced frequency chirping
(AIP Publishing, 1982-07-01)
Through numerical simulations, we show that, under relatively general conditions, passage of an intense picosecond pulse through a single-mode optical fiber can cause the pulse to become strongly frequency broadened with ...
Cloning and characterization of the cl repressor of Pseudomonas aeruginosa bacteriophage D3: A functional analog of phage lambda cI protein
(American Society for Microbiology, 1987-05)
We cloned the gene (cl) which encodes the repressor of vegetative function of Pseudomonas aeruginosa bacteriophage D3. The cloned gene was shown to inhibit plating of D3 and the induction of D3 lysogens by UV irradiation. ...
Comparison of the Pasteurella haemolytica A1 envelope proteins obtained by two cell disruption methods
(American Society for Microbiology, 1989-04)
The French pressure cell and sonication methods of bacterial cell disruption were compared for the evaluation of surface proteins from Pasteurella haemolytica Ai. Several protein bands were quantitatively different when ...
Potential for transduction of plasmids in a natural freshwater environment: Effect of plasmid donor concentration and a natural microbial community on transduction in Pseudomonas aeruginosa
(American Society for Microbiology, 1987-05)
Transduction of Pseudomonas aeruginosa plasmid Rmsl49 by the generalized transducing bacteriophage phi-DS1 was shown to occur during a 9-day incubation of environmental test chambers in a freshwater reservoir. Plasmid DNA ...
Pasteurella haemolytica antigens associated with resistance to pneumonic pasteurellosis
(American Society for Microbiology, 1989-03)
Antigens associated with whole Pasteurella haemolytica biotype A serotype 1, a capsular arbohydrateprotein extract of the organism, and P. haemolytica leukotoxin were separated by sodium dodecyl sulfatepolyacrylamide gel ...
Assimilation of cholesterol by Lactobacillus acidophilus
(American Society for Microbiology, 1985-02)
Considerable variation was found among strains of Lactobacillus acidophilus isolated from the fecal flora of pigs with regard to the ability to grow well in the presence of bile and to assimilate cholesterol from a laboratory ...
Electromagnetic shock waves from transmission lines
(American Physical Society, 1987-10-12)
We have observed subpicosecond electrical pulses to propagate on 5-pm coplanar transmission lines at velocities faster than the phase velocity in the underlying dielectric. This situation produces an electromagnetic shock ...
