Although we cannot clearly associate the tortoise carapaces with Grave VIII (Figure 3), articulated tortoise remains are not found in any other contexts at the site.
This study corroborates previous studies showing increased liver cancer mortality, but we cannot clearly associate rectal, stomach, and intestinal cancers with PCB exposure.
The present study adds to the body of knowledge regarding PCB-related health effects and corroborates previous studies showing an increase in mortality from liver cancers; however, we cannot clearly associate intestinal and rectal cancers with PCB exposure.
According to the fossil record, eukaryotes were already well diversified by ~ 1,500 Mya at the latest; however, these fossils cannot be clearly associated with any of the extant eukaryotic lineages [ 26- 29].
This result fits well with a previous study in yeast, which reported that non-conserved disordered proteins cannot be clearly associated with any function, and are expressed at low levels [ 5].
At least 46 transposases correspond to ISMae 1A/2/3/4 that had previously been characterized in strain PCC7806 [ 22], but a large majority of the other transposases cannot be clearly associated with any known insertion sequence (only 17 are associated to IS 30, 7 to IS 1 and 3 to IS 5).
An ambiguous (or uncertainty) zone can be defined around a membership degree value of 0.5, representing those patients for which a low or high risk profile cannot be clearly associated, i.e. their molecular grade profile is really intermediate (see "gray rectangle" on Figure 2).
One of these is specific to grasses, two are found in eudicots, and one is a collection of more distantly-related polypeptides, found in C. reinhardtii, P. patens, and S. moellendorffii, that cannot be clearly associated with any of the higher plant isoforms.
"That this focus on exports has persisted through periods both of economic success, as during the 1950s and 1960s, and of economic decline, as during the last 25 years and thus cannot be said to be clearly associated with one or the other seems to have escaped notice".
Direct 14C-dating of the pottery is thus necessary, as we cannot be sure which terrestrial samples are clearly associated with the pottery.
These findings cannot be attributed to influences of age, both of which are clearly associated with estradiol and grey matter density, since all the individuals included in the current cohort were 12 years at the time of the assessment.
