Images from the RS and following subdivisions and layers of the hippocampus were taken: stratum moleculare, stratum granulosum, and stratum polymorphe of the dentate gyrus; stratum oriens, stratum pyramidale, and stratum lucidum of the CA3 region; and stratum oriens, stratum pyramidale, and stratum radiatum of the CA1 region.
Finally, using the three sets of estimates created by the separate covariate analysis models in each of the direct strata, and taking the population distribution of the direct standardization variable, each site's quality indicators were weighted to a common population distribution on the direct standardization measure.
The urban and rural areas of each of the four provinces of Pakistan were taken as strata.
Surface concentrations are calculated by dispersing emissions in horizontal strata, taking chemical reactivity and transport processes into account.
By all accounts, they infiltrated the top political and economic strata, while taking command of a burgeoning mafia that spread murderously through the post-Soviet countries.
In statistics, stratified sampling is obtained by taking samples from each stratum or sub-group of a population, i.e., a mini-reproduction of the population is achieved; conversely, according the random sampling method, each sample is chosen entirely by chance in order to reduce the likelihood of bias.
Recruitment was done house-by-house, following stratified random sampling taking into consideration socioeconomic stratum, which was classified in 6 levels (A, B, C+, C, D+, D, from higher to lower) [ 9].
The results from this analysis were compared with the results of a sibling analysis in which we included a sibling stratum variable, taking the same value for individuals being full siblings.
Electron micrographs covering 64 µm2 (final magnification 20,000×) were randomly taken from the stratum radiatum and the stratum lacunosum-moleculare of the hippocampus, and the number of synaptic contacts was counted (n = 50 77 micrographs per layer and group).
As the strata take form, these brahma deities gradually descend into the lower realms and eventually become the first inhabitants of the new earth, from whom all humans descend.
