However, as the material density increased, the minimum fluidization velocity increased.
This occurred without any change in either material density or trabecular thickness (Tb.Th). in the oim/oim mice, while in the +/+ mice, material density increased slightly but significantly (+3%, P = 0.004), and Tb.Th.
The mean Bone Material Density (BMD) increased to 29.2 34.5% in 3-month-old OVXed rats compared to control-vehicle group (P < 0.001) and increased to 17.5 22.3% compared to sham-operated groups (P < 0.01).
Degradation of polymers is usually manifested in a reduction of molecular weight, increase of crystallinity in semicrystalline polymers, increase of material density, a subtle increase in yield strength, and a dramatic reduction in toughness.

In fact, such a reactive material presents antagonist behaviors for heat conductivity and gas permeability: increasing the reactive material density (i.e. the energy density) increases heat conductivity, but dramatically decreases permeability.
The density changes have a significant effect on the low-Z material, for example, when density increases from 0 to 1, gold represents a temperature difference of about 20 eV, while plastic represents a temperature difference about 160 eV; high-Z materials such as gold flow into their radiation emission (radiation regime), earlier than low-Z materials.
The increase in the calcination temperature increases the particle average size, reduces the surface area and increases the material density, considering the same phase and crystalline structure.
An increase in material density, i.e., shrinkage of the degraded layer is constrained by adjacent unchanged material results in a buildup of tensile stress within the degraded layer and compressive stress in the adjacent unchanged material due to increasing incompatibility between the two.
Although the infusing caused a detrimental 15 20% increase in core material density, the infused resin had little or no affect on toughness compared to non-infused balsa.
