Alternatives: "a minimal effect" or "a slight influence."
An incomplete curing and a high dose UV exposure have a weak impact on losses.
Capillary underfill and GSG transition pitch have been evaluated to have a weak impact.
However, excluding birds had no or only a weak impact on leaf damage.
The martensite hardness has a weak impact on the initial yield strength, but it significantly affects the flow behavior for sufficiently large martensite volume fraction.
Our study suggests that variations in precipitation that occur at a geological time scale (> 106 years) may have a weak impact on the erosion of landscapes and on the delivery of siliciclastic material to large rivers and sedimentary basins.
Michael Saunders of Salomon Brothers reckons that one leading source of recent M4 growth the bank deposits of what are categorised as "other financial institutions" (OFI), pension funds and life insurers among others will have a weak impact on inflation, because this money will mostly be saved, not spent like much of the deposits of individuals and other firms.
Modern earthquakes are more frequent, smaller in magnitude, and have a weaker impact on the region.
It has already been discussed elsewhere [26, 27] that the width of the InAs layer in these QWs is strongly correlated with the emitted wavelength, whilst the variation of the GaInSb layer thickness usually has a weaker impact on the transition energy.
Experimental studies of macroalgal impacts on P. astreoides led us to expect a weaker impact than that found for A. agaricites because P. astreoides has been found to be relatively resistant to Lobophora encroachment [32] and contact with Dictyota has reduced coral growth rate but not led to mortality [26].
In contrast, because RNA polymerases bind dNTPs weakly and their cellular concentration is low, dNTPs would exert a weaker impact on RNA polymerization.
