In particular, Klein et al. (2008) show that clinical immunity can act as a refuge for the wild type, non-resistant, strain, and in so doing, oppose the emergence of drug resistance at high transmission levels for which population structure shifts towards providing such a refuge.
At high transmission levels, there may not be much difference in the human epidemiology as a result.
Such studies are labor intensive and require populations with sufficiently high transmission levels such that enough clinical events are captured to have sufficient statistical power.
This patent states that "high transmission levels of blue and violet light (wavelengths from about 390 nm to about 500 nm) has been linked to retinal damage, macular degeneration, retinitis pigmentosa and night blindness.
Although the benefits of controlling reservoirs of human parasite infection with therapeutic drugs are intuitive, appealing, and well established, only limited impact can be expected where high transmission levels persist 18, 46, 50, 53 and the dangers of applying strong selection pressure for drug resistance upon robust parasite populations are also obvious.
Similar success may be harder to achieve in countries like Cameroon and the Democratic Republic of the Congo, which had higher transmission levels before treatment began and are home to black fly species that spread the worms more efficiently, Remme says.
In addition, after optimizing the device structures, we have obtained high Q-factor values, but with reduced optical transmission - in agreesment with our previous analysis, where we obtained a reasonably high optical transmission level, together with high Q-factor values.
We can utilize high transmission power level (100 mW) to reduce end-to-end delay since it can travel through small hop counts.
In the lounge and the first bedroom, which are one wall away from the receiver, we observe excellent reception at high transmission power levels that gradually drops as we decrease the transmission power level.
The study was performed for two transmission power levels, i.e. 10 dBm and 20 dBm, and has shown that high transmission power levels can significantly increase the RCR and UCR distances.
