We show that in Chinese households there exists a threshold for electricity consumption with respect to income, which could be considered a measure of electricity poverty, and the threshold differs between rural and urban areas.
However, both Platyophyra and Colpoda failed to eliminate EcO157, possibly due to the exhaustion of supplemental nutrients required to stimulate grazing or for reaching a threshold level for consumption by protozoan cells, as observed for the efficient consumption of non-pathogenic E. coli by T. pyriformis [32].
This indicated that pH 4.4 probably was a threshold for acid flush, pH below 4.4 resulted in the termination of glucose consumption.
The second potential explanation was that there is a threshold for when problems are counted as problems, and that this may vary; when consumption decreases, what is counted as a problem may also change, especially as observed in surveys.
The general sugars consumption in Laos is still far below the 15-20 kg/year observed as a threshold for a significant level of dental caries in a population [ 18].
This latest news really crosses a threshold for brazenness.
In contrast to the failure of protozoan grazing at a certain critical density of prey discussed above, populations of EcO157 (Figures 1 and 6) inoculated into wastewater directly were eliminated without a noticeable threshold for the consumption of EcO157.
Initial trials to determine the threshold for ethanol consumption by C. butyricum showed that the microorganism can consume ethanol up to a concentration of 25 mM (data not shown) and this could possibly explain the lack of net ethanol production.
The inconclusive nature of the body of research does not allow for the establishment of a non-harmful threshold for maternal alcohol consumption, and therefore, the public health promotion of no alcohol use during pregnancy is the safest measure to reduce fetal harm.
With the goal of developing a practical, efficient energy consumption protocol for wireless sensor networks, we introduced a threshold policy for the nodes in the entire network, where the sensors are distributed activated, whenever they are required.
