These nanocrystals extend all the way through the thickness of the specimen forming the columnar structure observed in the cross-sectional analysis.
The presence of mucus strands, normal flora, enzymes and inhibitory factors in sputum specimens forms the major hurdle in developing a standard diagnostic assay.
It contains more than 800,000 specimens of vascular plants, bryophytes, algae, lichens, and fungi, including almost 2000 nomenclatural type specimens; vascular plants (>400,000 specimens) form the bulk of the collection.
Natural history specimens form the core of a large, integrative network of information that can be used to address numerous questions regarding environmental and climate change.
Fossils as old as the Miocene have been referred to C. niloticus [2], [17]; whether these are conspecific with C. niloticus (or even assignable to Crocodylus) is doubtful [62], but some geologically younger specimens (e.g. specimens forming the basis of C. niloticus kaisensis from the Pleistocene of Uganda [63]) are more consistent with the living species than with C. anthropophagus (pers. obs).
One clade combined the marine cyclopoid copepods species, whereas the freshwater species specimens formed the second clade.
These biological specimens form the Generation R Study Biobank, which enables future epidemiological studies focused on environmental exposures, genetic determinants and their interactions in relation to growth, health and development from fetal life onwards.
The specimen forms a sample of initial cracks: the larger specimen, the larger is the sample.
The specimen that forms the core of the description is gorgeous, with dark grey bones preserved in exquisite detail, and that palaeontological happenstance is what has set off the hubbub over tyrannosaur foreplay.
