(1) The Osserman scale is a common classification scheme used to stratify patients with myasthenia gravis.

(2) Cold and moist conditions are necessary in order to stratify and break the seeds' dormancy.

(3) Untreated seed can be planted in the late summer/early fall and allowed to stratify under natural conditions.

(4) The residues have begun to stratify

(5) The predictor lakes were Trout Lake, a strongly stratified lake, and Allequash, a poorly stratified lake.

(6) Nevertheless, even here the stratification of classes does not appear in its pure form.

(7) The continental crust is not stratified like the oceanic crust and so does not have a characteristic seismic velocity structure.

(8) To optimise treatment, patients should be stratified into risk categories to allow the most appropriate prophylactic measure to be used.

(9) The seeds were stratified and germinated in a greenhouse at Rutgers University.

(10) With this index, patients are stratified into three risk categories based on their total points.

(11) We stratified patients by age and sex and calculated rates for all observations.

(12) One hundred and fifty stratified seeds were not used in this trial and continued to be stored in the freezer for a total of six months.

(13) Within each plot, monitoring sites were stratified by topography (into slopes and drainage lines) and proximity to the remnant edge (into inner and outer zones).

(14) Researchers stratified patients undergoing urologic surgery by invasiveness of the procedure and degree of contamination.

(15) This switch can, in part, be accounted for by the marked fall in sea level noted above, whereby normally stratified conditions are likely to become more indistinct.

(16) Since plant communities could influence soil processes, the plots were stratified into two broad vegetation classes: conifer and hardwood.

(17) Seeds were stratified at approximately 5Ôö¼ÔûæC in damp paper towels for 2-4 weeks and planted in flats.

(18) In a society stratified by economic classes, economic slavery will continue to exist even if the conditions for its abolition are possible.

(19) Seeds were imbibed and cold stratified in darkness for 4 days at 4Ôö¼Ôûæ to induce germination.

(20) Seeds were collected from individual plants and sown on moist soil, stratified for 4 days, and grown for 4 weeks.
