Summary.The autocatalytic equation in the form log x/(a â x) =K (tât1) may be used to express closely the changes which occur during growth.The constant k, as given by K = ka, is not a constant which is independent of environmental conditions.The changes in growth may be more suitably expressed by means of the equation dx/dt= (k1+ k2x) (a â x). In this

Artificial Life 14: Proceedings of the Fourteenth International Conference on the Synthesis and Simulation of Living Systems, 2014
Life on Earth must originally have arisen from abiotic chemistry. Since the details of this chemistry are unknown, we wish to understand, in general, which types of chemistry can lead to complex, life-like behaviour. Our recent work has shown that the inclusion of thermodynamic principles in simple artificial chemistry models can result in the ...

Autocatalysis in the formose reaction
Reaction Kinetics and Catalysis Letters, 1980It has been found that carbohydrates naturally present in ppm quantities in paraformaldehyde are the cause of the autocatalysis in the formose reaction of paraformaldehyde solutions. Paraformaldehyde sublimed into Ca(OH)2 suspension was not transformed to sugars by formose reaction, only to methanol and formate by Cannizzaro reaction. A minute trace of

Autocatalysis in prothrombin activation
American Journal of Physiology-Legacy Content, 1962Two enzymes, thrombin and autoprothrombin C, are derived from purified prothrombin by autocatalytic activation in 25% sodium citrate solution. The thrombin but not the autoprothrombin C activity is destroyed by diisopropylfluorophosphate. Autoprothrombin C is a procoagulant, which catalyzes the conversion of prothrombin to thrombin in a prothrombin ...

Autocatalysis and the Retooling of Society
BioScience, 1971with the quality of our environment. And yet the interpretation of what constitutes the public good is confounded by the human tendency to accept only that which is psychophysiologically comfortable while filtering out the painful components. Another confounding factor is the consciousness of immediate technological benefits while associated penalties ...
