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) ... -
PaeExo IX: A unique deoxyribonuclease from Pseudomonas aeruginosa active in the presence of EDTA
(Oxford University Press, 1979)A new deoxyribonuclease, PaeExo IX, has been purified to electrophoretic homogeneity from extracts of Pseudomonas aeruginosa strain PAO. This enzyme, which is active in the presence of EDTA, is equally efficient in hydrolyzing ... -
Companionship of knots and the smith conjecture
(American Mathematical Society (AMS), 1980)This paper studies the Smith Conjecture in terms of H. Schubert’s theory of companionship of knots. Suppose J is a counterexample to the Smith Conjecture, i.e. is the fixed point set of an action of Zₚ on S³. Theorem. Every ... -
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, ... -
Solution of the kinetic equations governing trap filling. Consequences concerning dose dependence and dose-rate effects
(American Physical Society, 1981-11-01)The equations governing the traffic of charge carriers during the filling, by ionizing radiation, of traps and luminescence centers in an insulator are numerically solved. The numerical solution is that of a set of four ... -
Measurement of the velocity distribution of sputtered Na atoms from NaCl by Doppler shift laser fluorescence
(AIP Publishing, 1981-11-01)The velocity distribution of sputtered Na atoms from NaCI during 15 keV, Ar+ bombardment was measured by a Doppler shift laser fluorescence technique. Contrary to other measurements, the sputtered Na atoms were found to ... -
Velocity distributions of sputtered excited atoms
(American Physical Society, 1982-02-08)The first direct measurements are reported of the velocity distributions of sputtered atoms in excited states with electronic configurations completely different from the ground state. In contrast to previous work, the ... -
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 ... -
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 ... -
Demonstration of age-dependent capsular material on Pasteurella haemolytica serotype 1
(American Society for Microbiology, 1982-12)Extracellular capsular material was demonstrated on early log-phase cells of Pasteurella haemolytica serotype 1 by the fluorescent-antibody and several capsular staining techniques. The presence of this material was shown ... -
Electrophoretic and antigenic comparisons of the ixodid ticks Amblyomma maculatum and A. americanum (Acari: Ixodidae)
(Florida Entomological Society, 1982-12)Disc gel electrophoretic patterns of female and male Amblyomma maculatum Koch extracts are similar but not identical. A comparison of combined male-female A. americanum (L.) with male and female A. maculatum extracts ... -
Immunocytochemical localization of acrosin on both acrosomal membranes and in the acrosomal matrix of porcine spermatozoa
(Medknow Publications, 1983)Immunocytochemical techniques were employed to determine, at the ultrastructural level, the location of acrosin in porcine spermatozoa. Antisera to highly purified porcine acrosin was produced in rabbits. The (Fab') fragments ... -
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 ... -
Observation of the formation of the 0-pi pulse
(American Physical Society, 1984-08-06)We have measured with 0.5-psec resolution the reshaping of small-area 7-psec laser pulses to 0-pi pulses due to their passage through an optically thick sodium cell. The reshaped pulses have a picosecond oscillatory structure ... -
Further research on the classification of mucoid strains of Pseudomonas aeruginosa

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 ... -
Susceptibility of feline herpesvirus 1 and a feline calicivirus to feline interferon and recombinant human leukocyte interferons
(American Society for Microbiology, 1985-11)Feline lung monolayer cultures were treated with either a feline interferon (IFN) or one of two recombinant human alpha-IFNs and then challenged with feline herpesvirus 1 (FHV-1), feline calicivirus (F-9 strain), or vesicular ... -
Presence of common antigens, including major surface protein epitopes, between the cattle (intraerythrocytic) and tick stages of Anaplasma marginale
(American Society for Microbiology, 1985-12)Epitopes of major surface proteins of the intraerythrocytic cattle stage of Anaplasma marginale were demonstrated in the midgut stage of the organism within the infective tick host Dermacentor andersoni. These proteins ... -
Simple visual assay for determination of Pasteurella haemolytica cytotoxin neutralizing antibody titers in cattle sera
(American Society for Microbiology, 1985-12)A simple visual assay is described for determining the capacity of bovine serum to neutralize the cytotoxin produced by Pasteurella haemolytica serotype 1. The test was reproducible from day to day with different target ... -
