We find producing oxygen vacancies at high temperature that are active in N2 reduction is the energetically limiting reaction step of the redox cycle.
We hypothesized that if breeding behaviour is energetically limited, then males should lose body condition between their first and last night in the breeding chorus.
This criteria may be met in long-tailed macaques as alpha males are able to discern the females' fertile phase (Engelhardt et al. 2004) are not energetically limited in their ability to mate-guard females (this study) and female fertile phases do not overlap (Engelhardt et al. 2006).
We also found that ATP hydrolysis is poorly coupled to nucleosome repositioning, suggesting that DNA translocation by ISWI is not energetically rate-limiting for the repositioning reaction.
As the ATP coupling efficiency for DNA translocation by other DNA translocases, including chromatin remodelers, is between 0.5 ATP/bp and 3 ATPs/bp, our result argues against the possibility that DNA translocation by ISWI is energetically rate-limiting for the repositioning reaction.
In fact, such consilience between two very different modeling frameworks raises the possibility of new hypotheses about energetically-regulated limits that amount to a global "carrying capacity" for fire.
In contrast, under nutrient deprivation, animals need to alter their metabolism to limit energetically costly processes, restrict growth and promote survival.
We find that formation of defect complexes is energetically favorable and limits hysteresis during inter-tube displacement of DWCNTs.
Angela Merkel, Germany's chancellor, is sufficiently worried about her industrial champions to lobby energetically against European Union limits on automotive carbon emissions.In this section Saving the Bush presidency Losing their vrroooom?
The redox pathways, even when energetically favourable tend to be limited by very slow reactions and must be aided by cofactors and ribozymes.
Non-wetting topographies, like the Sharklet micropattern, maintain air pockets among features that limit microorganism interaction and provide energetically unstable surfaces for bio-adhesion [37,61].
