At least two biological replicates should always be performed to use the within-treatment variation for determining statistical significance.
MR imaging in adenocarcinoma of the prostate: interobserver variation and efficacy for determining stage C disease.
Complete color development was attained instantaneously, however for higher precision readings, the reaction was allowed to proceed for 5 min. The developed color remained stable at room temperature for at least a further 30 min. Job's method of continuous variation was used for determining the molar ratio of ATR-Ca to DDQ.
Understanding patterns of adaptation in relation to spatial scale, gene flow and environmental variation is important for determining appropriate seed sourcing zones for restoration.
Determination of the emitted radiant energy released during biomass combustion episodes (the so-called fire radiative energy or FRE) has been suggested as a new tool for determining variations in biomass combustion rates and the rate of production of atmospheric pollutants.
This large range may be due to variations in techniques, criteria for determining positivity, and interobserver variability [ 7, 8, 15, 20, 28].
In addition, the hypervariable region is often particularly critical for determining variation among individuals that are closely related (i.e., intrapopulation variation).
Job's method of continuous variation [26] was used for determining the molar ratio of OLM to pCA.
Job's method of continuous variation [31] was used for determining the molar ratio of CLM to DDQ.
In the present paper, the authors suggest a new technique for determining variation in the geomagnetic field by using the H-component and present related methods of extracting geomagnetic perturbations, estimating their intensity, and determining periods of increased geomagnetic activity.
