Purification and properties of two deoxyribonucleases of Pseudomonas aeruginosa
(American Society for Microbiology, 1976-08)
A survey of the major deoxyribonucleases in Pseudomonas aeruginosa strain PAO was undertaken. Two activities predominated in Brij-58 lysates of this organism. These have been purified from contaminating nuclease activities, ...
Triethyl-n-hexylammonium triethyl-n-hexylboride: A new antimicrobial showing activity against Candida albicans and gram-positive bacteria
(American Society for Microbiology, 1975-10)
The organic salt triethyl-n-hexylammonium triethyl-n-hexylboride (N2226 B2226) has biostatic effects against two gram-positive bacteria, Bacillus subtilis and Micrococcus luteus, and the yeast Candida albicans. Escherichia ...
Self-induced adiabatic rapid passage
(American Physical Society, 1975-09)
We show that, by virtue of the linewidth reduction provided by counter-propagating beams, it is possible to use the optical Stark shift to sweep a two-photon resonance through the sum frequency of the applied light while ...
Prophage F116: Evidence for extrachromosomal location in Pseudomonas aeruginosa strain PAO
(American Society for Microbiology, 1977-06)
F116 is a temperate-generalized transducing phage of Pseudomonas aeruginosa. Genetic evidence leads to the conclusion that F116 prophage DNA is maintained extrachromosomally as a plasmid. Preliminary physical evidence is ...
Doppler-tuned hyperfine spectroscopy of the lithium ion
(American Physical Society, 1978-11-20)
We have used the Doppler-tuned ion-beam, laser-spectroscopy method to measure the hyperfine intervals in the 2^3 S and 2^3 P^o states of Li+. Our resolution was 10 times that of the best previous measurement. In contrast ...
Light-controlled light modulator
(AIP Publishing, 1977-10-01)
A fast resonantly enhanced light-controlled light modulator is demonstrated. Optical switching action is obtained with driving laser pulses with intensities as low as 2 kW/cm^2. The switching mechanism is the optical ...
An algebraic determination of closed orientable 3-manifolds
(American Mathematical Society (AMS), 1979)
Associated with each polyhedral simple closed curve j in a closed, orientable 3-manifold M is the fundamental group of the complement of j in M, π₁(M — j). The set, K(M), of knot groups of M is the set of groups π₁(M — j) ...
Theory of the dispersive modulator
(AIP Publishing, 1975-02-15)
The recent observations by Loy of amplitude modulation and compression of infrared laser pulses caused by passage through the dispersive modulator (a cell containing dilute NH3 vapor with a Stark-modulated resonant frequency) ...
Self-defocusing of light by adiabatic following in rubidium vapor
(American Physical Society, 1972-10)
The narrow-line output of a dye laser on the low-frequency side of the 2P1/2 resonance line (7948 A) of rubidium was self-defocused by passage through dilute rubidium vapor. The defocusing was caused by the electronic ...
Frequency of F116-mediated transduction of Pseudomonas aeruginosa in a freshwater environment
(American Society for Microbiology, 1978-11)
Transduction of Pseudomonas aeruginosa streptomycin resistance by a generalized transducing phage, F116, was shown to occur during a 10-day incubation in a flow-through environmental test chamber suspended in a freshwater ...
