Convective flow of oxygen into oil-sands-containing strata involves the influx of oxygenated, precipitation-derived (meteoric) waters, which are accommodated by current upward expansion following the melting of a 2-km-thick icecap overlying this region 10 000 years ago.
That is not to say that the transition from one stratum to another always involves sudden changes in morphology; on the contrary, fossil forms often persist virtually unchanged through several geologic strata, each representing millions of years.
Miliaria crystallina involves the stratum corneum, producing clear vesicles without erythema.
The upper epidermal layers were mostly involved (stratum spinosum, granulosum and corneum) and the authors identified cytokeratin 10 (CK10) (expressed by differentiated keratinocytes) as a target protein for CML modification.
Subsequently, however, surface uplift of the intermontane basin involved strata within the AB and resulted in the deposition of coarser sediments of the San Felipe Formation (Figs 1 and 2 35.
During the latter half of the 20th century, a coherent picture evolved of the underlying strata of matter involving two types of subatomic particles: fermions (baryons and leptons), which have odd half-integral angular momentum (spin 1/2, 3/2) and make up ordinary matter; and bosons (gluons, mesons, and photons), which have integral spins and mediate the fundamental forces of physics.
"The higher socio-economic strata is equally involved in such practices," she said.
The second involves adjusting for each individual stratum.
Due to the surface proximity of coal seams, mining has predominantly been open-cut which involves removing large volumes of overlying strata (referred to as spoil) to rapidly and completely extract economic coal seams at depths up to 200 m.
A stratified Cox model is performed with time-to-event outcomes, and involves calculating a hazard ratio within each stratum, then combining the results for a final estimate.
