Computational Simulation of Bray-Liebhafsky (BL) Oscillating Chemical Reaction

The computational simulation of the Bray-Liebhafsky (BL) oscillating chemical reaction by differential kinetic methodology is carried out in this work. According to the mechanism of Treindl and Noyes involving 10 reaction steps, the changes of the concentrations of I2 and O2 in solution are simulated. When the control parameters are α = 0.55, β = 0.2882 and δ < 0.6, the differential equations p...

Food-related bray calls in wild bottlenose dolphins (Tursiops truncatus).

Because cetaceans are difficult to study in the wild, little is known about how they use their sounds in their natural environment. Only the recent development of passive acoustic localization systems has enabled observations of the communication behaviour of individuals for correlation with their surface behaviour. Using such a system, I show that bottlenose dolphins in the Moray Firth, Scotla...

Teaching and learning audit 8 page profile – Bray Park shs

There is a strong and optimistic commitment by all staff to the school improvement strategy and a clear belief that further improvement is possible. Teachers take responsibility for the changes in their practice required to achieve school targets and are using data on a regular basis to monitor the effectiveness of their own efforts to meet those targets. The school has developed an agenda for ...

The Bray-liebhafsky and Briggs-rauscher Oscillating Reactions

The common points and differences between the Bray-Liebhafsky and BriggsRauscher reactions are discussed. The reactants of the non-catalyzed version of the Briggs-Rauscher reaction being the same as those of the Bray-Liebhafsky reaction plus a reducing organic compound, the mechanisms of these two systems must have several common points. The marked difference between the oscillating behaviours ...
