This paper proposes an assessment of African countries' growth patterns through the identification of acceleration episodes. About two-thirds of African countries have experienced at least one growth acceleration episode since the 1950s. In some cases, accelerations hardly contributed to long-term growth, as they led or lagged a crisis episode, but in most cases, which we define as growth ...

A positive value indicates an oxidized state, whereas a negative value indicates a reduced state. The Eh of milk is about +150 mV and that of cheese is about -250 mV.ORP / Redox. ORP (oxidation reduction potential) is typically measured to determine the oxidizing or reducing potential of a water sample. It indicates possible contamination, especially by industrial wastewater. ORP can be valuable if the user knows that one component of the sample is primarily responsible for the observed value. The reduction and oxidation potentials for a given species are identical in value but opposite in sign. In this chapter, only reduction potentials will be used to define redox properties, i.e., a higher reduction potential has a more positive value (see Fig. 1). Factors such as ionic strength, pH, temperature, or partial pressure of gasses can ...
