DDT limits of ethanol–air in an obstacles-filled tube
(2018-06-09)
Experiments were performed to study flame acceleration and deflagration-to-detonation transition (DDT) in ethanol–air mixtures in a tube filled with orifice plates with a blockage ratio of 0.44. Tests were conducted at ...
Mechanisms of prey size selecon in a suspension feeding copepod, Temora longicornis
(Inter-research, 2014-12-15)
We examined size-dependent prey detection and prey capture in free-swimming Temora longicornis using video observations, particle image velocimetry (PIV), and bottle incubations with phytoplankton prey sizes within the ...
Signaling-Dependent Control of Apical Membrane Size and Self-Renewal in Rosette-Stage Human Neuroepithelial Stem Cells
(Cell Press, 2018-06)
In the developing nervous system, neural stem cells are polarized and maintain an apical domain facing a central lumen. The presence of apical membrane is thought to have a profound influence on maintaining the stem cell ...
Particular features of gonadal maturation and size at first maturity in Atrina maura
(2012)
The gonadal maturation of Atrina maura was examined by means of histological analysis and quantitative criteria. Particular features not previously described for this species are reported in this study: in both males and ...
Size diversity as an expression of phytoplankton community structure and the identification of its patterns on the scale of fjords and channels
(Elsevier, 2011-03-01)
Large microalgae, such as diatoms can generate high levels of biomass, unlike small phytoplankton components in the austral Fjords and estuarine systems of Chile. We propose a cell-size-based diversity index (H'(size)) ...
