While wind energy production is relatively free from environmental externalities such as air pollution, it is frequently considered to negatively impact landscapes' visual aesthetic values, thereby inducing negative effects on tourism demand.
Parasites thereby exert negative frequency-dependent selection on their hosts, with the most common host genotypes having low fitness and declining in frequency as parasites infect them.
When added to the samples, successful amplification of this mimic demonstrated the absence of substances inhibitory to PCR, thereby validating negative results.
Amplification of these internal controls was used to confirm that rRT-PCR inhibitors were absent from clinical samples, thereby verifying negative assay results.
The elevated pH may have impacted the underlying soil by increasing soil pH and thereby increasing negative charge on the surfaces of variable charged minerals, which are abundant in oxisols.
The tryptophan repressor blocks the transcription and expression of the genes, thereby creating negative feedback regulation of the tryptophan synthesis process.
