Our findings demonstrate that cereals used as animal feeds are generally contaminated with variable levels of mycotoxigenic fungi and mycotoxins, with maximum levels being present in mixed cereals and maize samples.
Despite the consistency shown in these studies between adult rated AoA and objective AoA based on child data, recent studies, however, have also found that the objective AoA is a more powerful determinant of naming latency than rated AoA [13], probably because the former is less contaminated by other variables [14], [15].
Our development is carried out under a practical setting where a validation sample is impossible but repeated measurements of error-contaminated variables are available.
Crops imported for feed production have often been contaminated with highly variable concentrations of aflatoxins; an estimated average concentration of at least 140 micrograms aflatoxin B1 kg-1 prepared mixed cattle feed prevailed in the past, yielding a daily intake for workers via the respiratory route of approximately 170 ng.
A linear regression model using COF as the dependent variable and tread groove width, tread groove orientation, footwear material, floor, and contaminated conditions as independent variables was established.
For the dependent variable, surfaces contaminated with C. difficile, statistically significant contrasts were identified between C. difficile exposed patient rooms versus MRSA exposed patient rooms (OR 14.88; P = 0.012) and cork surfaces versus fabric surfaces (OR 10.33; P = 0.009).
Regression data often suffer from the so-called Berkson measurement error which contaminates the design variables.
Nevertheless, even in the latter option, the welfare variable can be contaminated by differences in preferences.
Initial colony size was used for statistical analyses, rather than colony size averaged over the incubation interval, because we wanted to avoid contaminating the independent variable (colony size) with parameters that could be influenced by the dependent variable (growth rate).
However, similar work has not been done when the random variables or vectors are contaminated with measurement errors.
Two sum scores were constructed from 5 variables yielding "Transmission through contaminated instruments"(unsafe blood transfusion, contaminated blood transfusion, contaminated sharp instruments) and "Transmission through shaking hands and eating" (shaking hands, eating). in addition to the one item assessing "Condoms are safe prevention".
