This indicates that life achieved a relatively rapid global presence and had diversified enough (Kandler 1994; Altermann and Schopf 1995; Ueno et al. 2006; Blank 2009; David and Alm 2011) to occupy a wide variety of ecological niches by the Paleoarchean, even in places that may have been severely disturbed by asteroid impacts (see Walsh 1992and references therein).
This TCE disappearance was more rapid in presence of 0.2% benzene and 0.2% chloroform as compared to that of 0.2% toluene.
An accelerated failure time model with a Weibull survival function was used to assess the effect of test type (i.e., real-time RT-PCR or rapid culture), presence of measured or subjective fever, and viral load (of the first available serial sample) on duration of viral shedding.
In our initial model using data from all 16 participants, which included test type (real-time RT-PCR vs. rapid culture), presence of fever (measured and subjective), and viral load as predictors of shedding duration, test type was the only significant variable (p = 0.02).
In a semi-final billed as the battle of the attacking guns it was Cristiano Ronaldo, a relentless, rapid-fire presence, who finally zeroed his sights and settled this game.
A popular guest on TV news programs and talk shows, a Google-booster often quoted in print, and a rapid-fire presence on San Francisco's social scene, she is the rare executive who has become — at least in the sometimes cloistered world of computer geeks — a celebrity.
Catalyst deactivation was more rapid in the presence of sulfur, at low S/C ratios, and at lower temperatures.
The reaction is also extremely rapid in the presence of up to a 10 6 -fold excess of noncomplementary sequences, establishing that renaturation is specific and relatively independent of heterologous DNA.
However, the decay of the peak calcium response to histamine was more rapid in the presence, compared to the absence, of estradiol.
Transport of d-xylose has been found to be related to d-glucose transport, since the influx of d-xylose or d-arabinose is more rapid in the presence of glucose under anaerobic conditions than under aerobic conditions (Jeffries 1983).
It is generally observed that NW growth is rapid in the presence of a catalyst [35] in accordance with the fact of vapor liquid solid synthesis mechanism where the radius of NWs is measured by the size of the catalyst particle; although compared to conventional CVD growth, the interplay between the NWs and metallic catalysts seems to be more complicated.
