0 the mass of a particular volume of a substance when compared with the mass of an equal volume of water at 4°C. A more modern name for this is relative density.
Hosts arranged in order of increasing specific gravity and hardness (see table 4).
The specific gravity and moisture content (w/w) of each wood sample were determined by displacement and oven drying methods, respectively.
We therefore assumed a mean wood specific gravity equal to 0.63 g cm-3 for all the trees in the plots.
The introduction of a slight negative buoyancy (with specific gravity 1.03) helped to retain the beads in the bottom layer during motion.
The long life span of this species may be caused by wood durability with a high specific gravity and abundant defensive compounds.
We also developed a different strategy to estimate the wood specific gravity of the trees in our plots.
The simplest method of measuring the specific gravity of a liquid is the hydrometer.
Using this method, it is possible to obtain the specific gravity of 1 cc. of fluid.
