Using a Heckman two-step approach, the results confirmed that the decision to contribute depends on behavioural and motivational factors, while the amount is income-dependent.
But how much they can contribute depends very much on how much they are forced to spend in the primary.
This empirical study shows that derivational analogy is almost always more efficient than problem solving from scratch, but the amount it contributes depends on its ability to overcome mismatches and to usefully interleave reuse with from-scratch problem solving.
In other circumstances there is a shared stability scenario and the amount contributed depends on fragment contact and the fracture pattern.
Numerous experiments with EF-Tu mutands and modified aa-tRNAs have established that, while all three regions contribute to the affinity of aa-tRNA to EF-Tu, the relative amount that each region contributes depends strongly upon the identity of both the tRNA body and its esterified amino acid.
We have a number of ongoing research projects on which a student could take the lead or contribute depending on interests and background, particularly related to improving risk prediction for lethal prostate cancer, developing genetic signatures for prostate cancer risk factors, analyzing gene expression profiling data, and metabolomics.
Nor can users easily find communities to which they may contribute, depending on their competencies, skills and centres of interest.
The motion of dislocations 1/2 <110] is achieved by either or both glide and climb, the degree to which these various mechanisms contribute depending on the temperature and strain rate.
The number of surrounding follicle layers that contributed depended on the species and radioiodine isotopes and was 2, 1 and 8 for 123I, 125I and 131I, respectively, in the human model.
On the positive side, the main source of vitamin D is usually endogenous synthesis from exposure of the skin to solar ultraviolet-B (UV-B) [ 2], although dietary intake can contribute, depending on food types, fortification and supplementation practices [ 3].
