Studying three types of foraminifera, single-celled organisms that make up much of the world's plankton, the scientists have discovered that northern and southern specimens of the same species display some identical genetic variation.
Although magnetite has been found in some skulls of the common dolphin (Delphinus delphis), it has not been found in other specimens of the same species, and no conclusive data indicate its biological use.
For example, a hoard of some 70 Roman gold coins found at Vidy, Switzerland, did not contain any two specimens of the same type, which implies that the coins were collected during the period of Roman rule in that town.
Also, it sometimes diverges among specimens of the same material subjected to similar experimental conditions.
For the first time, researchers have specimens of the same type--canine teeth, in this case--from all three hominids.
Mechanical recycling consisted of regrinding of specimens and further injection moulding the granules into specimens of the same type.
Between specimens of the same method, the percentile deviations were 11.5%% (CCM), 10.3 % (CBT) and 14.1 % (CBBM).
In this paper, fourteen independent sets of laboratory measurements were performed on specimens of the same porous materials.
New fossils uncovered in northeastern China show that two specimens of the same species of dinosaur, one juvenile and one adult, featured distinctly different feathers.
Few disparities that were observed in this otherwise general trend may be attributed to varying surface properties of the AIBC, even among specimens of the same group.
Finally, the fatigue strength of the additively manufactured specimens was compared with that exhibited by vacuum melted specimens of the same steel reported in literature.
