The 9-million-year-old sediment coarse at creek level becomes finer grained as Rigsby traces the layer upward.
The epithelial cells increase in size as they migrate from the basal layer upward toward the superficial layer [ 29].
This process starts when proliferating keratinocytes of the basal layer move upward to the suprabasal layers and progressively acquire the ability to express sequentially the specific gene products that are required for differentiation [45].
These currents create sedimentary deposits called turbidites, which are layers up to several metres thick composed of sediment particles that grade upward from coarser to finer sizes.
The layer with sedimented drug or textile material was oriented downwards, and the mucoadhesive layer faced upward.
The gas hydrate layer builds upward from the base of the stability zone with a thickness of less than 100 m.
They turned on the radiogenic heat of the lowermost mantle, sent slabs descending from the top, and found that the bottom layer swelled upward in places and thinned beneath slabs--just like a lava lamp.
We are most interested, herein, in one form of ESF, equatorial plasma bubbles (EPBs), which are initiated in the bottomside of the equatorial F layer, with upward development into the topside ionosphere.
Retinas were flat mounted with the ganglion cell layer facing upward on Millicell-CM chamber (0.4 μm culture plate insert, 30mm diameter; Millipore,Bedford, MA, USA).
The coverslips were then mounted with the cell layer facing upward on aluminum scanning electron microscopy (SEM) stubs using sticky tabs.
