Fluctuation in reported POAF incidence due to differences in rhythm follow-up is illustrated by the comparison of the following three studies.
"The UK's welcoming approach to Bitcoin contrasts with the approach of other countries, amid concerns about its use for tax evasion and money laundering as well as its notoriety for wide fluctuations in value," reports The Financial Times.
Although some of the annual fluctuation in reports and cases might be attributable to an actual increase or decrease in disease, the substantial changes seen indicate that the principal factor most likely resulted from changes in surveillance method over time.
Whereas a shorter period, such as in the UK, USA or Australia, could have overwhelmed the health services, causing larger fluctuations in the reporting delay.
As our reported error rates are based on a sampling of facts from the respective databases, we expect fluctuation in the reported error rates each time the validation exercise is repeated.
Table 3 shows the average nutrient contents (Nitrogen, Phosphorus and Potassium) of various types of vermicomposts reported by different authors, which show that vermicompost is a rich source of nitrogen phosphorus and potassium but there is high fluctuation in compositions reported by different workers.
Current temporal outbreak detection evaluation methods include testing using long outbreak-free datasets, and inserting a simulated outbreak at multiple points during this dataset to enable reporting of averaged detection abilities which account for typical fluctuations in baseline disease reports over time (e.g. [ 24]).
In D. subobscura no seasonal fluctuations were reported in some works [ 50, 51], but fluctuations and seasonal changes of associations between chromosomal inversions and allozymes were reported in others, specially in the O chromosome from original populations [ 52, 53].
Measurements of mean and fluctuating velocity and temperature fields, mean concentration of major chemical species, correlation between velocity and temperature fluctuations, and dissipation of temperature fluctuations are reported in a turbulent round jet non-premixed propane flame, Re=20 400 and 37 600, issuing vertically in still air.
The foaming cause could be the temperature fluctuations as reported in the case of BP A. According to Eder and Schulz [24], sudden temperature changes of more than 1 K are very problematic, especially for thermophile biogas processes.
