It is shown that the standard slope ratio and parallel line models for bioassay can be considered as approximations to the logistic in the extreme dose regions, while the parallel line model can be ...

Therefore, a mathematical model is proposed to utilize the logistic function. The function was defined as an overall response including time, temperature, and the interaction between time and ...

Although this model is in its early stages on the continent, aggregation shows strong potential for improving and unifying logistics for Africa’s importers and exporters.
