However, the above qualitative estimates of antimicrobial usage is different of the quantitative estimate of usage, where sulfonamides was by far the most used in quantitative terms, followed by tetracyclines and fluoroquinolones.
We ascribed to each stretch of line the estimate of usage (1=low, 2=medium, 3=high, 4=very high) presented in Atlas of Great Britain (1975), which was based on both passenger numbers and train frequency derived from a survey in 1975.
For background, eMarketer forms its estimates for advertising spending on Twitter through an analysis of estimates of consumer usage, marketer usage, ad pricing, and impressions on Twitter, as well as revenue estimates from research firms and other sources.
Estimates of test usage in Germany indicate that for use of FOBT within the past year, only 14% of men and 22% of women were compliant, and that colonoscopy use within 10 years was 23% for men and 26% for women [ 8] though in most instances the colonoscopy was diagnostic rather than for screening.
First, estimates of antibiotic usage that are based on prescription data are likely to result in considerable underreporting of antibiotic usage in the community.
Half received water-saving tips and weekly estimates of their usage; the other half served as a control.The households that were urged to use less water did so: their consumption fell by an average of 6% compared with the control group.
We assume the wind patterns at each site are representative of the county as a whole and, using capacity factors of 20% (residential) and 35% (commercial), we estimate the amount of electricity that can be generated for the county and compare it to county-based estimates of electricity usage.
It seems relevant to include the effects of substitutional asymmetries in estimates of codon usage bias.
Even though distinguishing such small values is beyond the ability current technology, estimates of isoform usage occasionally contain them.
Estimates of isoform usage were often similar between IUTA and Cuffdiff2 even when they differed in declaring a gene to have differential isoform usage between tissues.
