Although many shareware options do not offer as many features as the Adobe Acrobat program, they cost less and might be better for those with a less frequent need to create PDF files.
Positive selection of sperm proteins, combined with frequent retrotransposition to create genes encoding sperm-specific proteins, results in the faster evolution of genes involved in sperm function [ 44].
Although Sulfolobus, like bacteria and other archaea, do not reproduce sexually, recombination is frequent enough to create a discontinuous signature of interacting evolutionary forces in the genome.
This correlation further suggests that, even between these species with different current population sizes, selection is frequent enough to create a significant relationship between polymorphism- and divergence-based comparisons of selection in both species.
Thanks to the ubiquity of smartphones and big data, gamification is now prevalent in practically every industry, though some of its roots are in travel, going back to the early 1980s, when American Airlines introduced its AAdvantage frequent flier program to create brand loyalty.

"In the first place he was too busy", explains Saintsbury, "in the second he would not have been at home there.... [H]e felt it was his business not to frequent society but to create it".
After discarding trials with artifacts (e.g., eye blinks, large eye movements), MEG trials from Blocks 1 and 3 were concatenated, as were the trials from Blocks 2 and 4. For each wrist, ~150 trials of rare MEG responses and ~850 trials of frequent responses were averaged to create two averaged files––one for rare and one for frequent responses.
Montessori techniques build on these skills and habits, with the goal of improving quality of life and independence by using cognitive strengths to neutralize weaknesses, making frequent use of repetition to create unconscious learning.
These wells of space and color exemplify Judd's frequent use of surprise to create suspense and clarity; they also reflect his origins in painting and his lifelong admiration for the simple forms and strong colors of painters like Barnett Newman, Mark Rothko and Josef Albers.
