It is,demonstrated that certain cobalt compounds which are autoxidation catalysts a t low concentrations become inhibitors a t higher concentrations. I n all these cases inhibition implies a lengthening of the induction period, but only in a few systems (N-alkylamide + cobaltous acetate) is the inhibitory effect observable beyond the induction period. I n the case of hydrocarbons and cobalt(I1) salicylaldimines the rate of oxygen uptake beyond the substantially increased induction period is not reduced even at the highest catalyst concentrations. A reaction mechanism and a kinetic scheme, consistent with the novel experimental observations, are proposed.
ZUSAMMENFASSUNG:Es wird gezeigt, da13 gewisse Kobaltverbindungen, die in geringer Konzentration Sutoxydations-Katalysatoren sind, bei Konzentrationserhohung inhibierend wirken. I n allen diesen Fdlen fiihrt' die Inhibierung zu einer Verlangerung der Inkubationszeit, aber n u bei manchen Systemen (N-Alkylamid + Kobaltacetat ) wird Retardierung auch nach dem Ende der Inkubationszeit beobachtet. Im System Kohlenwasserstoff + Kobalt(I1)-Salicylaldiminkomplex wird trotz einer sehr bedeutsamen Verlangerung der Inkubationszeit nach deren Ende sogar bei den hochsten Konzentra+ionen keineVerzogerung der Sauerstoffaufnahme gefnnden. Ein Mechanismus und ein kinetisches Schema, welche die neuartigen Versuchsergebnisse erklaren, werden vorgeschlagen.(C22H44), 2,6,10,14-tetramethyIpentadecane, methyl linoleate, and cobaltous acetate in N-n-butylacetamide.

This modified Delphi panel sought to gain clarity from clinical experts surrounding the use of dressings in the management of chronic wounds. A full consensus statement was developed to help clinicians and policy makers improve the management of patients with these conditions.
with NPH therapy had changed their treatment. Conclusions: The prescription of modern therapies in the beginning of the treatment is preferred over the therapy with NPH, increasing the preference as time passes. Patients who start with modern therapies are more stable in their treatment than patients who start with NPH therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
