Data from northern and western parts of the Horn suggest slow migration of Sudanese groups and/or dense contacts with transfer of techniques and practices, beginning in foothills near today's Sudan border and, at least in the North, slowly spreading deep into the highlands of the Horn.
Also the characteristic dense contacts between type A cells (Doetsch et al., 1997) were less evident in the SVZ of EAE mice (Supplementary Fig. 2).
When neutrophils are in more-dense contact with CD4+ T cells, as in the spleen, they can provide co-stimulatory signals promoting T-cell differentiation.
The increase of the MWCNTs will lead to the formation of a dense physical contact network.
At an injection current of 20 mA, the LEDs with GRIN ITO AR coating show 24.3%% higher light output than the reference LEDs with dense ITO contact.
Culturing HepG2 in 3D resulted in hepatocyte-like morphology with expression of bile canaliculi and dense cell cell contacts (Kelm et al. 2003).
It is possible that hypoxia (and also dense intercellular contacts) upregulate expression of endosialin to relieve pericyte endothelial interactions and/or to modulate local tumour stroma, and thereby facilitate migration of dividing endothelial cells and sprouting of new blood vessels.
One can see that three layers between the porous PSFC cathode, SDC or SDC LiNaSO4 (20 wt%), and the dense YSZ electrolyte contact each other well.
As a matter of fact, the connection between rivet and laminate can be modelled with FE models presenting 3D dense meshes and contact elements (Urban 2003; Al-Emrani and Kliger 2003) obtaining a high accuracy in local results, but at the same time very large calculation times when multi-joined parts are studied.
