The bombardment of planetary and satellite surfaces by debris left over from the main accretionary stage continued intensively for another 600 million years, but these impacts contributed only a few percent of the mass of any given object.
As matter of fact, the bulk of participants contribute only a few moves before leaving the system.
Taken together, our results indicate that high affinity hydrogenase activity is proportional to the abundance of H2-oxidizing bacteria in soil and, that abiontic hydrogenases contribute only a few percent of the total high affinity H2 oxidation activity detected in soil.
It can be argued that xenoestrogenic equivalents contribute only a few percent to the endogenous hormone activity – even when possible higher bioavailability of the xenobiotics is taken into consideration.
Amid this regulatory controversy, it may appear puzzling that in order to reduce exposure to a cumulative toxicant like Cd, the European Union amended the regulation by selectively targeting only foods eaten during infancy and cocoa, a healthy food contributing only a few percent of dietary Cd intake (EFSA 2012).
The analysis of variance was performed by GLM-ANOVA and subsequent pairwise comparisons were assessed with Tukey's procedure accounting for both animal factor and stage factor and the fact that some animals contribute to only a few stages.
Individual neurons may contribute only with a few spikes to the visual processing during each fixation, suggesting precise spike timing as a relevant mechanism for information processing.
While many countries contributed to both journals, only a few of them were responsible for the majority of all articles.
Many variants with small effects may contribute to fracture risk, but only a few vitamin D-related genetic polymorphisms have been reported to be associated with fracture risk [ 33].
Among the other psychosocial variables only a few contributed to the prediction and included some variables that were assessed in early adolescence, namely, low scores on the internalizing dimension which is just the correlate of the externalizing problems, heightened self-awareness, and a feeling of lacking possibilities to participate at school.
