Catalysis of the deprotonation of β-diketones during formation of the 1:1 metal complexes
(Canadian Science Publishing, 1992-08-01)
Catalytic effects on the deprotonation rate constants of beta-diketones were observed during kinetic studies of the formation reactions of the 1:1 complexes of these ligands. When vanadium(IV), chromium(III), iron(III), ...

Catching the light curve of a flaring grb. the opportunity offered by gravitational lensing
(EDP Sciences, 1999-09-01)
The photometric history of the events related to Gamma-Ray Bursts can be studied from the very beginning, or even before, if they are repeated (at least two times after the first event) by effect of gravitational lensing. ...
Positive solutions for a class of nonlinear singular boundary value problems at resonance

Effect of helicobacter pylori lipopolysaccharide (lps) and lps derivatives on the production of tissue factor and plasminogen activator inhibitor type 2 by human blood mononuclear cells
(Oxford University Press (OUP), 1996-12-01)
Different Helicobacter pylori lipopolysaccharides (LPSs) and LPS-derivatives were studied for their ability to induce the production of procoagulant activity (PCA) and plasminogen activator inhibitor type 2 (PAI-2) by human ...
Limits to quantum gravity effects on energy dependence of the speed of light from observations of tev flares in active galaxies
(American Physical Society (APS), 1999-09-13)
We have used data from a TeV gamma-ray flare associated with the active galaxy Markarian 421 to place bounds on the possible energy dependence of the speed of light in the context of an effective quantum gravitational ...
The stereochemical course of reactions catalysed by the cellobiohydrolases produced bytalaromyces emersonii
(Portland Press Ltd., 1992-04-01)
Three forms of exocellobiohydrolase (EC 18.104.22.168), CBH IA, CBH IB and CBH II, were isolated to apparent homogeneity from culture filtrates of the aerobic fungus Talaromyces emersonii. CBH IA and CBH II appear to be native ...

Tectonic interpretation of regional conductivity anomalies
(Springer Nature, 1994-03-01)
This review paper selects key result, from electromagnetic induction studies of a variety of distinctive tectonic phenomena in the top 200 km of the Earth. Its main theme is that electromagnetic data are essential for an ...
