The dates given here are only approximations of the time of the documentary fixation of the dates.
Think of an idea for a date.
This database contains the following data: country, age, sex, operated side, diagnosis, date of primary THA, hospital code, type of fixation of the prosthesis, type of bone cement, date of death (if applicable), and cause and date of eventual revision.
According to Enard et al 2002, the fact that these two differences are fixed in the human genome, whereas no fixed substitutions occurred in the lineage of our closest relatives, the chimpanzees, suggests that those changes were strongly selected for in our lineage; Enard et al. put the date of fixation of these changes in the human population at around 200,000 years ago.
Thus, fixation of the adenine at position −237 in Symphalangus likely dates to a point in gibbon evolution after the fixation of the thymine at position −1072 and is a derived condition in that clade.
The age of the blocks/sections was determined by identifying the duration between the date of fixation (date of surgery) and the date of extraction (arrival date at the Peter MacCallum Cancer Centre).
But the fixation of New Yorkers on the two other incidents reflected a darker cast of mind.
A major improvement on the fixation of biological specimen occurred with the introduction of cryo-fixation.
We have a word — dogged — to describe the dedicated fixation of canine attention.
Moreover, by integrating chromosome painting data, molecular dating, and an explicit phylogenetic framework, one can infer evolutionary trajectories and estimate rates of fixation of chromosome rearrangements within particular lineages [ 13].
