Although patients will be aware of the existence of two treatment arms, they are not informed about the exact content of the other treatment arm (e.g. determining intensity) to prevent influence on outcomes.
For example, light intensity appears to influence the beneficial effects of ocean acidification on N2 fixation in cyanobacteria and its detrimental effects on calcification in coccolithophores (Kranz et al. 2010; Rokitta and Rost 2012).
These results indicate that grazing intensity and precipitation interact to influence carbon cycling on mixed-grass prairie ecosystems.
Gender of the farmer, dependency ratio, credit access, presence of cash crop, distance to extension services and agro-ecological potential were found to influence intensity of fertilizer use.
However, the effectiveness of various educational strategies is not conclusive and factors such as time and intensity have been proposed to influence outcomes [ 18].
Likewise, dim nocturnal light at moonlight intensity has been shown to influence circadian clock gene expression levels and timing in Drosophila, resulting in elevated nocturnal activity under laboratory conditions (Bachleitner et al., 2007).
As the context of the primary health care setting makes it difficult for GPs to provide the intensity of intervention required to influence health literacy and behaviour change it is important the referral mechanisms to intensive programs or other health professionals are available.
The stretching and relaxation classes were optional and considered light-intensity physical activity inadequate to influence CRF or produce significant increases in strength.
A robust signal certainty is also adapted to the sample intensities to minimize the influence of outliers.
Also, many parameters such as wind direction, foliage density, and urban configuration are believed to influence the intensity of trees effects.
