It turns out that sediment and rock — the compressed geological strata of the ages — do not bury anyone as irrecoverably as does the invisible, accumulating strata of time itself.
Although the term craton is often taken as synonomous with tectonic quiescence, the North American craton is not simply an unchanging, stable platform accumulating strata and influenced only by changes in global sea-level.
Following topical administration, CMS accumulated in the stratum corneum without penetration into deeper viable epidermal layers.
e, h FLIM analysis confirmed that CMS-ICC exclusively accumulated in the stratum corneum in healthy mice and in mice with atopic dermatitis, based on data analysis of unique fluorescence decay curves (g, j) from tissue autofluorescence (cyan) and from CMS-ICC (red).
If the glucosylceramides accumulated in the stratum corneum in dogs with atopic dermatitis while ceramides decreased, the glucosylceramide ceramide ratio would increase.
Thus, substances accumulated in the stratum disjunctum are rapidly eliminated by the shedding of the outermost layers, whereas the SC can function as a reservoir for those particulate materials penetrating deeper.
When the tracer molecule biotin was applied to the dermal side of organotypic skin models, it did not reach the stratum corneum in control samples (Fig. 6A, left panel), whereas the substance readily penetrated through all nucleated epidermal layers and accumulated in the stratum corneum of histamine-exposed samples (Fig. 6A, right panel).
Fine materials accumulated primarily at lower strata (<1 m) throughout the chronosequence, whereas leaves and coarse materials accumulated first at lower strata, and then progressively occupied the upper strata (>1.5 m).
In most instances of such cyclic sedimentation, the bedding, or stratification, is horizontal or essentially so; that is, the transporting, sorting, and depositing agents of wind, running water, and lake and ocean currents and waves accumulated the laminae and strata in a flat-lying or horizontal arrangement.
I lay on my back considering the strata of accumulated road filth, spots of tar, and oil coating the wheel wells, tires, and front axle.
