gravity

 [grav´ĭ-te]
1. the phenomenon by which two bodies having mass are attracted to each other.
2. the gravitational attraction near a large body having mass, particularly near or on the surface of a planet or star.
specific gravity see specific gravity.
standard gravity (€g) the acceleration due to gravity at mean sea level, 9.80616 meters per second squared.

specific

 [spĕ-sif´ik]
1. pertaining to a species.
2. produced by a single kind of microorganism.
3. restricted to a particular structure or function, such as in application or effect.
4. a remedy specially indicated for a particular disease.
5. in immunology, pertaining to the special affinity of antigen for the corresponding antibody.
specific gravity the weight of a substance compared with the weight of an equal amount of some other substance taken as a standard. For liquids the usual standard is water. The specific gravity of water is 1; if a sample of urine shows a specific gravity of 1.025, this means that the urine is 1.025 times heavier than water. (The normal specific gravity of urine is 1.003–1.030.) Specific gravity is measured by means of a hydrometer.

spe·cif·ic grav·i·ty (sp. gr.),

specific gravity

Lab medicine A measure of the solutes in a fluid; SG is detected in the urine, based on the response of a polymeric acid to surrounding ions. See Dipstick. Cf Nitrites Nephrology The SG reflects the kidney's ability to concentrate urine: if a random urine specimen has an SG > 1. 023, the kidney's ability to concentrate is assumed to be normal ; SG ↑ in SIADH, uncontrolled DM, proteinuria, eclampsia and obstructive uropathy and ↓ in renal tubular damage, chronic renal insufficiency, diabetes insipidus, malignant HTN Occupational safety A physical parameter of a liquid that indicates how heavy it is in relationship to air–≤ 1.0 = lighter than water; ≥ 1.0 = heavier than water, a datum of interest to OSHA, which requires listing of SGs in its Materials Safety Data Sheets

In the work the different RVE models of structure were created and their properties were compared at different relative density, different numbers and the size and structure of the arrangement of voids.
However, some species had markedly high relative density in all sampling sites, such as Geitlerinema splendidum (Greville ex Gomont) Anagnostidis, Trachelomonas volvocina Ehrenberg and some diatoms (e.

Yes, there is a test to measure the minimum density: ASTM D 4254 Test Methods for Minimum Index Density of Soils and Calculation of Relative Density.
It was also revealed that addition of 15 wt.% aluminium titanate has increased the relative density and decreased thermal expansion coefficient (TEC) (6.9A-10-6/C) and electrical conductivity (3.1A-10-4 Ohm.cm) in comparison with other composites.
