Our data testify to ubiquitous and continuous transport of stone artefacts of a wide variety of forms, picked by Neandertals using selection criteria that were sometimes far removed from what archaeologists have traditionally considered, and to some degree still consider, to be desired end products of knapping activities.
In this work, a new contactor is described in which continuous, countercurrent transport of dense particles in a stationary, liquid fluidized bed of light particles is exploited to obtain selective and continuous transport of the dense phase.
There is therefore continuous transport of sodium from the lumen into the interstitial space [29].
The continuous transport of mucus toward the proximal trachea and esophagus limits any accumulation of particles within the conducting airways.
On the other hand, the concentration of salt in FC decreased due to the continuous transport of ions from these compartments.
The former occurs upstream and is responsible for continuous transport of the particles, whereas the latter occurs downstream and rapidly traps the particles delivered from upstream.
Besides, continuous transport of electrons among CdSe NTs would be confined and interrupted at times if the interconnection of CdSe NTs is destroyed by the many surrounding CdTe NTs, a thick potential barrier inhibiting electron transfer.
The fact that alkaline phosphatase activity in the conditioned medium continued to increase for up to 60 min (Figure 1B), whereas no difference in cell surface levels was observed, indicates that continuous transport of substrate to the plasma membrane occurs, which is then immediately processed.
As the nascent polypeptide chain emerges into the cytosol, interaction with Hsp70 is crucial for the continuous transport of the polypeptide through the ribosome channel into the cytosol (Nelson et al., 1992).
In response to the potential generated by the continuous transport activity of LacY, the voltage dependence of k4 leads to a decay of the currents at >20 ms, which is taken into account in the model.
