In addition, the countries studied differed in standard of living, which may affect outcome [ 23] and therefore indirectly, the prevalence of stigma.
We first tested for differences between groups (Baltic coast, coastal lakes, inland no predators, inland predators) using a general linear mixed model (GLMM) using group as a fixed factor and population nested within group as a random factor to ascertain whether groups significantly differed in standard length and the number of dorsal spines.
Commonly used generic drugs are usually made by a variety of companies, which differ in manufacturing standards and quality.
"Standards differ in different parts of the country," he said, explaining that crud in Utah might mean powder in Michigan.
Studies might differ in the gold standard, severity of disease, or in the application of the diagnostic test.
We applied a label-free quantification method using nano-flow liquid chromatography coupled with tandem mass spectrometry (nanoLC MS/MS) to assess X. laevis liver proteins that differ in abundance between standard laboratory rearing temperature (22°C, control condition) and low environmental temperature (5°C, cold exposure).
Services may differ in their quality standards and intervention intensity.
Males paired in trials differed in their standard length by 0.1 1.5 cm and in the red dorsal fin area by 0.4 21.9%.
It is shown that methods proposed earlier by Myers and Prausnitz [14], by Cook and Basmadjian [16], by Lewis [11] and by Arnold [3] are based upon the assumption of an ideal adsorbed solution but differ in their choice of standard states.
Given that adjacent probes within a single gene may differ in signal with a standard deviation >1 (on a log2 scale) [35] we have the option to create a very conservative dataset by selectively removing probes using the results of the gcRMA algorithm [11] run on the original raw dataset, in comparison to the dataset returned by the normalization procedure described above.
