An harmonic lattice theory is used, in conjunction with Mura’s theory of eigendistorsions, to study the structure and energetics of nascent dislocation loops in face-centredcubic (FCC) crystals. An analytical expression for the activation energies of such loops is derived. The results obtained herein indicate that thermal activation of small dislocation loops is possible at high stress levels s...

The database used by Hemmingsen (1960) to compute energy metabolism in unicellular organisms was reassembled and submitted to linear (log-log) analysis. As Hemmingsen noted, this data set includes marine zygotes, which are not unicellular organisms. If no temperature correction factors are applied to the data the best-fit regression line has a slope of 0.698 +/- 0.024. Application of the temper...

Methods of estimating riverine hydrokinetic (HK) power for localized and regional studies are reviewed, evaluated, compared. It was found that HK were not entirely consistent, with the most common discrepancies being discharge variability characterization, uncertainty analysis, amount data used to derive results. The issues associated assessments amplified assessments. Regional less common, met...
