Autoxidation of tetralin in water catalysed by cobalt(ii)-pyridine complexes bound to polymer colloids
(Royal Society of Chemistry, 1988)
Cobalt(ii)-pyridine complexes bound to 60 nm diameter latex copolymers of styrene, divinylbenzene, and either acrylic or methacrylic acid catalyse autoxidation of tetralin in water faster than cobalt(ii)-pyridine complexes ...
High-brightness terahertz beams characterized with an ultrafast detector
(AIP Publishing, 1989-07-24)
We have significantly improved the emission and detection of electromagnetic beams of single-cycle 0.5 THz pulses, through the use of new dipolar antenna structures. The frequency response was extended to well beyond the ...
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 ...
Contractible open 3-manifolds which are not covering spaces
(Elsevier, 1988)
Monoclonal antibodies to Pasteurella haemolytica serotype 1 lipopolysaccharide: Demonstration of antigenic similarities among several serotypes
(American Society for Microbiology, 1988-05)
Murine monoclonal antibodies (MAbs) were produced which were specific for Pasteurella haemolytica serotype 1 lipopolysaccharide (LPS). The MAbs also reacted with LPS present in a partially purified antigen derived from a ...
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 ...
Subpicosecond electrical pulse generation using photoconductive switches with long carrier lifetimes
(AIP Publishing, 1989-03-13)
Using a new mechanism of electrical pulse generation, we have generated 350 fs (full width at half maximum) electrical pulses on a coplanar transmission line, fabricated on an unimplanted silicon-on-sapphire substrate.
Capacitance free generation and detection of subpicosecond electrical pulses on coplanar transmission lines
(Institute of Electrical and Electronics Engineers, 1988-02)
Based on a reanalysis of previous work and new experimental measurements, we conclude that the parasitic capacitance at the generation site is negligible for sliding contact excitation of small dimension coplanar transmission ...
Expression of the recA gene of Pseudomonas aeruginosa PAO is inducible by DNA-damaging agents
(American Society for Microbiology, 1988-05)
Western (immunoblot) analysis using Escherichia coli anti-RecA antiserum revealed that expression of the RecA protein of Pseudomonas aeruginosa PAO is induced upon exposure of the bacterium to UV irradiation or norfloxacin, ...
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 ...
