Interestingly, the GT densities of upper leaves in Ex1 in several stress treatments (Fig. 3A) were decreased, as opposed to the increased densities of upper leaves observed in several treated groups of Ex2.
Investigation of control plants during a 5-week period (Fig. 6A) showed constant densities of GT on lower leaves, whereas GT densities of upper leaves increased slightly, but non-significantly.
Kernel density estimation of upper and lower density for the parameters.
The significant decrease in GT density on upper leaves of Ex1 (Fig. 3A) was possibly due to the dilution effect mentioned above.
An article in Pravda, broadcast by Moscow radio, said such a project was plausible in the light of available data about the density of the upper layers of the atmosphere.
Comprehensively, the cross-arranged graded honeycomb cores with higher density of the upper layer performs the best under the blast loading compared with the other configurations, taking the effects of graded cores and arranged orientations into consideration.
Then the isostatic vertical motion forms the EB (density of the upper layer around the equator is lower than the density in the polar regions).
The average density of the upper crust, which mainly consists of sedimentary cover, greenschist and granite, is 2750 kg/m3 (Hou et al. 2010; Wang et al. 2014b).
As a secondary objective, the instrument suite on board of the Swarm satellites allows the derivation of the neutral density of the upper atmosphere, i.e. the thermospheric density, and, if conditions are favorable, also thermospheric winds.
The density of the upper atmosphere varies according to many factors, and this means that Hubble's predicted position for six weeks' time could be in error by up to 4000 km.
